  The robot transport device 15 is used in combination with, for example, a horizontal articulated robot and an elevating mechanism, and transports the workpiece W or the molded product M to the robot hand 15a using both gripping or mechanical holding and suction. . FIG. 1 shows an example of holding a circular (round) semiconductor wafer as a workpiece. The workpiece W is gripped by pressing at least one holding claw while in contact with the holding claws 15b provided at three places on the robot hand 15a. The robot hand 15a is rotatably connected to the arm because the direction in which the workpiece W is set in the mold differs from the direction in which the workpiece W is accommodated in each accommodating portion.

  In addition, the workpiece processing unit Uw performs workpiece W thickness measurement (die count, semiconductor chip height measurement, etc.), workpiece W array (plurality) as pre-processing for the workpiece W before being formed and taken out from the workpiece storage unit 13. The pre-processing unit 16 that performs at least one of the work W and the reverse of the front and back of the work W may be provided. In this case, the amount of resin supplied by the resin supply unit Ud may be determined by measuring the thickness of the workpiece W, or an identification mark (such as a square type two-dimensional code or barcode) previously given to the workpiece W may be used. The amount of the resin supplied may be determined by reading the height of the semiconductor chip measured in advance by reading. The robot transfer device 15 delivers the workpiece W from the workpiece storage unit 13 to the preprocessing unit 16 and delivers the workpiece W preprocessed by the preprocessing unit 16 to the work loader 1.

In addition, the work processing unit Uw performs post-processing on the molded product M taken from the work loader 1 by turning the molded product M upside down, inspecting the molded product M, post-curing the molded product, cooling the molded product M, and post-use film You may provide the post-processing unit 17 which performs at least 1 process among accommodation of these.

The robot transfer device 15 receives the molded product M from the work loader 1 and delivers it to the post-processing unit 17, and stores the molded product M post-processed by the post-processing unit 17 in the molded product storage unit 14.

Note that the configuration of the work processing unit Uw is not limited to the above-described mode, and may be configured to be divided into a first processing unit 18 and a second processing unit 19, for example, as shown in FIG. In this case, the 1st process part 18 is good also as a structure provided with the workpiece | work accommodating part 13, the molded article accommodating part 14, and the functional unit which performs at least 1 process among the pre-processing unit 16 and the post-processing unit 17. FIG. For example, the work storage unit 13, the preprocessing unit 16, and the post-processing unit 17 (cooling unit) are arranged in the first processing unit 18, and the molded product storage unit 14 and the post-processing unit 17 (curing unit) are arranged in the second processing unit 19. A furnace) may be arranged.

In the case where a film collection unit is provided as the post-processing unit 17, the work loader 1 can also remove the used single-wafer film F and the suction pad 4c when the work hand 4 takes out the molded product M from the mold 21. The single-wafer film F taken out by being held by suction may be collected by a film collection unit (not shown).
Further, instead of providing a film recovery unit in the post-processing unit 17, a film recovery mechanism may be provided in the vicinity of the mold die 21 of each press unit, and the operation of recovering the single wafer film F by the work loader 1 may be omitted. .

Next, an example of the molding operation of the resin molding apparatus will be described with reference to FIGS. The workpiece W will be described assuming a semiconductor wafer as an example.
FIG. 4 shows an operation of transporting the workpiece W before molding to the workpiece storage unit 13 to the pretreatment unit 16 by the robot transport device 15. The workpiece W is gripped from the magazine by the robot hand 15a and transferred to the preprocessing unit 16. In the pre-processing unit 16, since the workpiece W is stored in an arbitrary direction in the magazine, uniform orientation is achieved by aligning the orientation by aligning the orientation of the workpiece W by rotating the workpiece W. Is possible. Further, die count of the workpiece W, thickness measurement of the workpiece W, and the like are performed. At this time, the work W is in a state in which the semiconductor chip mounting surface faces upward as in the case where the work W is accommodated in the magazine.

  Next, as shown in FIG. 5, the robot transport device 15 receives the workpiece W from the preprocessing unit 16 and delivers the workpiece W to the workpiece loader 1 that is waiting at the end of the rail 2 on the workpiece processing unit side. At this time, the hand drive unit 5 rotates 90 degrees counterclockwise with respect to the longitudinal direction of the work loader body 3 around the rotation shaft 3a, and waits in a direction in which the work hand 4 follows the rail 2.

On the other hand, in the robot transfer device 15, the robot hand 15 a holding the workpiece W is rotated 180 degrees, and the posture of the semiconductor chip mounting surface is changed from upward to downward, and then the outer periphery of the workpiece W is placed on the workpiece holder 4 b of the workpiece hand 4. Deliver by holding.

  Further, the preprocessing operation of the work processing unit Uw shown in FIG. 5 and the resin supply operation in the resin supply unit Ud are performed in parallel. In other words, while the pre-processing operation is performed in the work processing unit Uw, the resin supply operation is performed in a superimposed manner in the resin supply unit Ud. Specifically, the film cutout portion 10b is cut (cut) into a rectangular shape of an arbitrary size in a state where the film end is drawn out from the roll film 10a, and cut out on the resin mounting portion 10c as a single wafer film F. . A resin R (granular resin) stored in the hopper 10d in a state where a rectangular conveyance jig 12 is superimposed on the sheet film F and a necessary tension is applied to the sheet film F and supported. ) Is uniformly supplied onto the single wafer film F through the trough 10e that can be scanned in the XY direction. For example, the uniform resin R can be supplied by moving the trough 10e into a shape such as a shape in which parallel lines are arranged within a circular range, a concentric circle shape, or a spiral shape. At this time, the resin loader 6 stands by at the end of the rail 2 extending toward the resin supply unit Ud.

  Next, as shown in FIG. 6, the work loader 1 that has received the workpiece W moves along the rail 2 to a position (intermediate position) facing the first press portion P1 and the second press portion P2. The hand drive unit 5 rotates 90 degrees in the clockwise direction around the rotation shaft 3 a and the posture of the work hand 4 is changed to a position where it overlaps the work loader body 3. Then, the work hand 4 is caused to enter the linear motion rail 5a provided in the hand drive unit 5 toward the mold die 21 of the first press part P1 which is opened. The workpiece W held by the workpiece holding portion 4b of the workpiece hand 4 is delivered after being aligned with the clamp surface of the upper mold 23. Specifically, the workpiece hand 4 is lifted with respect to the upper clamp surface, and the surface of the workpiece W on which the semiconductor element is not mounted is pressed against and held by the upper clamp surface provided with the suction holes. (See FIG. 2).

  At this time, in the resin supply unit Ud, the resin hand 8 provided on the hand drive unit 9 of the resin loader 6 moves on the linear motion rail 9a and enters the resin mounting unit 10c. Then, the resin R is delivered to the resin loader 6 by gripping the opposite sides of the conveying jig 12 with the sheet film F to which the resin R has been supplied by, for example, a claw-shaped jig holding portion 8b. The resin hand 8 holding the resin R and the sheet film F via the conveying jig 12 is retracted from the resin mounting portion 10 c onto the hand driving portion 9.

Next, in FIG. 7, the work hand 4 that has entered the mold 21 that has been opened in the first press part P <b> 1 is retracted onto the hand driving unit 5, and the work loader 1 is moved along the rail 2 to the work processing unit. Move to Uw side and wait.
In this state, the resin supply operation by the resin loader 6 is started. The resin loader body 7 is moved along the rail 2 to a position (intermediate position) opposite to the first press part P1 and the second press part P2. The resin loader 6 moves the resin hand 8 provided on the hand drive unit 9 along the linear motion rail 9a to enter the first press part P1 that is opened. Then, the jig holding portion 8b aligns the conveying jig 12 and the lower mold 29 and lowers the resin hand 8 to release the chuck of the sheet film F by the conveying jig 12, and the lower mold clamping surface and lower By adsorbing and holding in the mold cavity, the resin R together with the sheet film F is delivered to the lower mold 29.

In the state where the resin hand 8 is returned to the hand drive unit 9, the resin loader main body 7 moves again along the rail 2 to the resin supply unit Ud side. Further, as indicated by an arrow in FIG. 7, it is preferable that the robot conveyance device 15 holds the next workpiece W from the workpiece container 13 and conveys it to the pretreatment unit 16 to perform the pretreatment.
Although not described in detail, the conveyance jig 12 held by the resin hand 8 of the resin loader 6 may be used for the next resin conveyance, or the jig storage unit 30 of the conveyance jig 12 (see FIG. 10). In addition, they may be stocked or cooled in preparation for the next resin supply operation.

  In the first press part P1, when the workpiece W is supplied to the upper mold 23 and the resin R is supplied to the lower mold 29 as shown in FIG. 11, the mold 21 is closed and compression molding is performed. Specifically, the lower mold movable platen 24 is raised with respect to the upper mold fixed platen 22, the upper mold 23 and the lower mold 29 are closed, and the resin R is heated and cured while the workpiece W is clamped.

  While the resin mold operation is performed in the first press part P1, the work supply operation to the second press part P2 is performed. As shown by the arrows in FIG. 8, the robot transport device 15 receives the next workpiece W that has been pre-processed from the pre-processing unit 16, and waits for the workpiece loader 1 ( Deliver the workpiece W to the workpiece hand 4). At this time, in the resin supply unit Ud, the resin R is supplied to the film F held by the transport jig 12 set in the resin mounting portion 10c.

  The work loader 1 that has received the workpiece W moves along the rail 2 to a position (intermediate position) facing the first press part P1 and the second press part P2 as shown in FIG. As shown by the arrows in the figure, the posture of the hand drive unit 5 is changed so that the work hand 4 overlaps the work loader body 3 by rotating 90 degrees counterclockwise about the rotation shaft 3a. Then, the work hand 4 is moved on the linear motion rail 5a provided in the hand drive unit 5 toward the mold die 21 of the second press part P2 which is opened. The workpiece W held by the workpiece holding portion 4b of the workpiece hand 4 is delivered after being aligned with the clamp surface of the upper mold 23.

  At this time, in the resin supply unit Ud, the resin hand 8 provided on the hand drive unit 9 of the resin loader 6 moves on the linear motion rail 9a and enters the resin mounting unit 10c. Then, the jig holding portion 8b retracts the sheet film F supplied with the resin R to a position where the resin hand 8 overlaps the hand driving portion 9 while holding the opposite sides of the conveying jig 12, and the resin R Is delivered to the resin loader 6.

  The work loader 1 is moved along the rail 2 to the work processing unit Uw side to be put on standby. In this state, resin supply operation to the second press part P2 by the resin loader 6 is started. The resin loader body 7 is moved along the rail 2 to a position (intermediate position) opposite to the first press part P1 and the second press part P2. Then, the hand drive unit 9 is rotated 180 degrees clockwise around the rotation shaft 7a to change the posture, and then the resin hand 8 provided on the hand drive unit 9 is moved along the linear motion rail 9a to form a mold. It enters into the opened second press part P2. Then, the conveying jig 12 and the lower mold 29 are aligned, the resin hand 8 is lowered, the chuck of the sheet film F by the conveying jig 12 is released, and the sheet film F is moved to the lower mold clamping surface and the lower mold cavity. The resin R is delivered to the lower mold 29 together with the sheet film F by being sucked and held inside.

  In the second press part P2, when the workpiece W is supplied to the upper mold 23 and the resin R is supplied to the lower mold 29 as shown in FIG. 11, the mold 21 is closed and compression molding is performed. Specifically, the lower mold movable platen 24 is raised with respect to the upper mold fixed platen 22, the upper mold 23 and the lower mold 29 are closed, and the resin R is heated and cured while the workpiece W is clamped.

  On the other hand, in the first press part P1, the molded product M after compression molding is received by the work loader 1 waiting at a position (intermediate position) opposite to the first press part P1 and the second press part P2, as shown in FIG. Then, the work hand 4 enters the mold mold 21 that has been opened, the molded product M is delivered from the upper mold 23 to the work holding portion 4b, and the sheet film F is sucked from the lower mold 29 by the suction pad 4c. to recover. Then, as shown in FIG. 5, the work loader 1 is moved along the rail 2 to the work processing unit Uw side, and the hand driving unit 5 is rotated 90 degrees counterclockwise to stand by. The robot transport device 15 receives the molded product M from the work hand 4 by the robot hand 15a, reverses it 180 degrees, and transports it to the post-processing unit 17 with the mold surface facing upward. Note that the used single-wafer film F adsorbed by the adsorption pad 4c is desirably collected in a separate collection box.

  In the post-processing unit 17, the molded product M is subjected to appearance inspection (post-cure is performed if necessary) and cooled, and the post-processed molded product M is held by the robot transport device 15 and is stored in the molded product storage unit. 14 in a magazine.

Similarly, the molded product M compression-molded by the second press part P2 is taken out by the work loader 1 and accommodated in the molded product accommodating part 14 via the post-processing unit 17 by the robot transport device 15 provided in the work processing unit Uw. .
Hereinafter, the workpiece conveyance operation and the resin supply operation for the first press part P1 are performed in parallel, and the same resin molding operation is repeatedly performed.

As described above, the press unit Up has a configuration in which the first press part P1 and the second press part P2 are arranged to face each other so as to intersect (orthogonal) the transport direction of the transport part C, so that the installation area is long. It can be prevented from becoming long in the direction and can be arranged compactly.
Further, since the distance that the work loader 1 moves on the rail 2 is the same between the first breath part P1 and the second press part P2, the transport distance of the work W and the molded product M is shortened.

  Further, in the resin molding apparatus, the first press part P1 and the second press part P2 are arranged to face each other so as to intersect (orthogonal) the rail 2 of the transport part C, and the work processing unit Uw and the resin supply unit Ud are arranged in the press unit Up. Since the rails 2 are arranged so as to be connected to both sides of the rail 2, the rails 2 can be shared by the first press part P1 and the second press part P2 for work conveyance and resin conveyance. Therefore, the conveyance distance of the work loader 1 required for the workpiece supply operation and the molded product storage operation from the workpiece processing unit Uw to the first and second press portions P1 and P2 can be similarly processed in a short time. Similarly, the transport distance of the resin loader 6 required for the resin supply operation to the second press parts P1 and P2 can be processed in a short time. Further, the expandability of the pre-processing function or the post-processing function in the work processing unit Uw is high, and the type and the supply method of the resin R of the resin supply unit Ud can be arbitrarily selected, so that versatility is improved.

  According to the press unit Up described above, the installation area can be reduced, the work area can be reduced, the operability can be improved, and the conveyance distance of the workpiece W and the resin R can be made uniform, thereby improving the molding quality. Moreover, by providing the press unit Up mentioned above, the resin mold apparatus with high expandability which is compact and has many functions can be provided.

  Moreover, although embodiment mentioned above demonstrated the case where the sheet | seat film F was conveyed and delivered to the lower mold | type clamp surface in which the lower mold cavity of the mold was formed, the upper mold in which the upper mold cavity was formed You may make it convey and deliver the sheet | seat film F with respect to a clamp surface.

  Moreover, the conveyance jig 12 mentioned above can be suitably used for resin-molding a workpiece W having an arbitrary shape such as an outer circular shape or an outer rectangular shape. For example, in order to resin mold an outer rectangular work W, the resin R is supplied in a rectangular shape by accommodating each part configured in a circular or annular shape in the above-described configuration and accommodated in a rectangular cavity. The formed rectangular workpiece W can be molded.

  For example, the workpiece W may be resin-molded on both surfaces of the workpiece W. In this case, after resin molding is performed on one surface of the workpiece W, the workpiece W is returned to the workpiece processing unit Uw, and the molded product M is reversed by the robot hand 15a of the robot transport device 15, and then the other side of the workpiece W (molded product M). A resin mold may be formed on the surface.

Also in this embodiment, the press unit Up described above, the resin supply unit Ud that supplies the resin R to the press unit Up, and the work processing unit Uw that supplies the workpiece W to the press unit Up and accommodates the molded product M are the same. This is common to the first embodiment in that it is provided in the order of arrangement. However, the work processing unit Uw is not necessarily provided as a configuration of a semi-automatic resin molding apparatus that automates only the supply of the resin R.

  Here, the configuration of the resin supply unit Ud will be described. The resin transport unit Ud is connected to one side surface (the right side surface in FIG. 1) in the longitudinal direction of the transport unit C so that the rail 2b extends from the transport unit C. The first resin supply unit 10 and the second resin supply unit 11 are arranged so as to be adjacent to the extended rail 2b in the same direction. The configuration of the first resin supply unit 10 is the same as that of the first embodiment with respect to functions other than the layout differing with respect to the conveyance unit C, and thus description thereof is omitted here.

Although the 2nd resin supply part 11 in this embodiment is provided with the function equivalent to the 2nd resin supply part 11 in 1st Embodiment in the point which can supply resin R on the sheet | seat film F, from a viewpoint of installation area reduction. Since the arrangement of the internal structure varies greatly, it will be described in detail.
That is, in the second resin supply unit 11, as shown in FIG. 14, a roll film storage unit 10A that stores the roll film 10a and a revolver type syringe supply unit 11c that rotatably holds a plurality of syringes 11b are vertically moved. Overlaid on. The film F drawn out from the roll film 10a is cut into strips at the film cutout portion 10b. Thereby, the roll film 10a and the syringe 11b can be exchanged from the front of the apparatus (the front of the apparatus), and the apparatus area can be reduced. In addition, the film cut portion 10b and the film cut into the film cut portion 10b between the syringe supply portion 11c and the roll film storage portion 10A, which are stacked one above the other, and the conveyance portion C (rail 2b) (inside the apparatus) A resin mounting portion 10c for mounting (supplying) liquid resin R on F is provided.

A remaining amount sensor 10g for detecting the remaining amount of the roll film 10a is provided in the vicinity of the installation position of the roll film 10a. For example, the remaining amount sensor 10g can be configured to provide an arbitrary position in the radial direction of the roll film 10a so as to sandwich the light emitting element and the light receiving element. In this case, the remaining amount sensor 10g generates a detection signal when the remaining amount (outer peripheral position) of the roll film 10a falls below a predetermined position, and prompts replacement of the roll film 10a.

  On the other hand, the syringe supply unit 11c is configured to be able to hold the plurality of syringes 11b at an arbitrary height by moving up and down the revolver structure that rotatably holds the plurality of syringes 11b. In other words, the 2nd resin supply part 11 is provided with the syringe raising / lowering part 11d which raises / lowers the syringe supply part 11c. The syringe elevating part 11d is configured by vertically arranging a linear motion mechanism including a linear guide, a ball screw, and a motor, for example. Thereby, it becomes possible to raise / lower the frame 11e which hold | maintains the revolver structure provided with the several syringe 11b. Here, the frame 11e is configured to open on the front surface side of the second resin supply unit 11 and on the inner side of the apparatus so that the syringe 11b can be transferred in the front surface direction (left side of the paper surface) and in the inner direction (right side of the paper surface). be able to.

  Moreover, as shown to FIG. 14 (A) (B), the 2nd resin supply part 11 hold | maintains the syringe 11b, the dispenser 11f which discharges the resin R, and the dispenser 11f in the XYZ direction (front-back, left-right, up-down direction) And a dispenser drive mechanism 11g to be moved. The dispenser 11f receives and holds the syringe 11b held in the syringe supply unit 11c by a syringe holding part provided in the columnar dispenser main body, and advances the piston in the syringe 11b, so that the tip (lower end) of the syringe 11b is moved. Resin R is discharged from the nozzle. Further, an elastic tube may be provided in the nozzle at the tip of the syringe 11b, and a pinch valve that sandwiches the tube and restricts the discharge of the resin R may be provided. In addition, a shutter (not shown) for closing the lower part of the nozzle may be provided so as not to contaminate the inside of the apparatus due to the resin dripping from the nozzle tip.

  The dispenser drive mechanism 11g is provided so as to be connected to the upper part of the dispenser main body of the dispenser 11f, and includes a plurality of linear motion mechanisms so that the dispenser 11f can be moved to an arbitrary position in the XYZ coordinates. Further, the dispenser drive mechanism 11g may have a structure including a parallel link mechanism instead of the linear motion mechanism. According to this, the dispenser 11f can be configured to be movable to an arbitrary position on the XYZ coordinates at a low cost.

  The resin loader 6 receives the sheet film F loaded with the resin R from either the first resin supply unit 10 or the second resin supply unit 11 together with the conveying jig 12, moves on the rail 2b, and moves to the first. It supplies to either the press part P1 and the 2nd press part P2 (refer FIG. 13). The resin loader 6 grips and conveys the opposite side of the transport jig 12 by the resin hand 8 (jig holding portion 8b). At this time, since the rails 2a and 2b are provided overlappingly, the work loader 1 whose movement range overlaps with the resin loader 6 is positioned so as not to interfere with the conveying operation of the resin loader 6 on the rail 2a (first press portion P1 and Retreat to a position avoiding the front of the second press part P2. The first resin supply unit 10 and the second resin supply unit 11 are not necessarily provided so as to coexist, and only one second resin supply unit 11 may be provided via the rail 2b. Only the second resin supply unit 11 may be provided side by side via the rail 2b.

  In FIG. 13, a configuration example of the work processing unit Uw will be described. The work processing unit Uw is connected to the other side surface (left side surface in FIG. 1) of the transport unit C in the longitudinal direction. The workpiece processing unit Uw is similar to the first embodiment in that the workpiece storage unit 13, the molded product storage unit 14, the robot transfer device 15, the preprocessing unit 16, and the postprocessing unit 17 are used. The difference is that a film recovery unit 17a for recovering the sheet F is provided independently. The film collection unit 17a in the present embodiment is provided between the robot transport device 15 and the press unit P1. In addition, the film collection unit 17a is provided with a rail 2a that is connected to the rail 2a of the press unit P1 so that the work loader 1 can move.

  For this reason, the rail 2a provided in the film collection | recovery part 17a also comprises a part of conveyance part C. FIG. Moreover, in the film collection | recovery part 17a, the delivery part 2c which hold | maintains the workpiece | work W or the molded article M temporarily is provided in the area | region which overlaps with the rail 2a extended from the press part P1. Specifically, when the work loader 1 that moves on the rail 2a moves on the rail 2a of the film collection unit 17a, the delivery unit 2c passes the workpiece W and the molded product M held by the workpiece hand 4. In the position.

  The delivery unit 2 c is configured to be able to hold and lift the workpiece W and the molded product M, and relays delivery of the workpiece W and the molded product M between the robot hand 15 a and the workpiece hand 4. That is, the delivery unit 2 c receives the work W for which preprocessing has been completed from the robot hand 15 a and delivers it to the work hand 4 of the work loader 1. Moreover, the delivery part 2c receives the molded product M resin-molded in the mold 21 from the work hand 4 of the work loader 1 and delivers it to the robot hand 15a. In this way, in the delivery of the workpiece W and the molded product M, the robot hand 15a and the work hand 4 are not directly delivered between the robot hand 15a of the robot transport device 15 and the work hand 4 of the work loader 1. It is not necessary to move to the position where the hand is delivered at the same time. Therefore, the plurality of workpieces W and the molded product M can be efficiently conveyed without causing these waiting times.

  Unlike the first embodiment, the robot transport device 15 has a configuration for more reliably preventing the workpiece W and the molded product M from falling off when the front and back are reversed. Prepare. That is, as shown in FIG. 15, the robot hand 15a includes a hand body 151, a fixed claw portion (holding claw) 152, a movable claw portion (holding claw) 153, a claw driving mechanism 154, a suction circuit 155, a suction hole 156, and a pad. Part 157. Here, FIG. 15A shows the configuration of the robot hand 15a in plan view, and FIG. 15B shows the configuration of the robot hand 15a in side view.

  The hand main body 151 is provided, for example, by branching into a plurality of (for example, two) claws, and supports the workpiece W and the molded product M as a whole. The hand main body 151 is configured to be rotatable in the circumferential (roll) direction Dr of the arm 15e at the tip of the arm 15e rotating with respect to the vertical axis in the horizontal articulated robot transport device 15. A plurality of the fixed claw portions 152 are provided by being erected on the branched tip portion of the hand main body 151. Further, the fixed claw portion 152 functions as a holding claw that presses and holds the main surface (front surface) of the outer edge of the workpiece W or the molded product M by expanding the diameter of the tip.

The movable claw part 153 has the same shape as the fixed claw part 152, and a plurality of movable claw parts 153 are provided on the base side of the hand main body 151. The shapes of the fixed claw portion 152 and the movable claw portion 153 may have a configuration (hook shape) other than the illustrated shape as long as the main surface (surface) at the outer edge of the workpiece W or the molded product M can be pressed and held. Further, the movable claw portion 153 moves back and forth with respect to the fixed claw portion 152 (in other words, the workpiece W and the molded product M to be held), thereby making the interval between the movable claw portion 153 and the fixed claw portion 152 variable.
The claw drive mechanism 154 includes a drive source such as an air cylinder (not shown), and drives the movable claw portion 153 in the advancing and retracting direction with respect to the workpiece W and the molded product M. The claw driving mechanism 154 advances and retracts the movable claw portion 153, so that the workpiece W and the molded product M can be switched between holding and releasing.

  The suction circuit 155 is provided in the hand main body 151 and is connected to a decompression device (not shown). The suction holes 156 are opened at a plurality of locations on the holding surface of the work W and the molded product M of the hand main body 151, and suck the air through the suction circuit 155 to suck the workpiece W and the molded product M. The pad portion 157 is made of an elastic body such as an O-ring or a rubber sheet, and is provided so as to surround the suction hole 156. Accordingly, the pad portion 157 elastically closes the gap between the workpiece W or the molding surface M to be held and the suction hole 156, and maintains these suction states.

  Note that it is preferable to use all of these configurations as one unit from the viewpoint of the effect described later. However, as a modified example of the robot hand 15a, a hand main body 151, a fixed claw portion 152, a movable claw portion 153, and a claw driving mechanism. It is good also as a mechanical holding structure provided only with 154. As another modification of the robot hand 15a, a suction holding structure including only the hand main body 151, the suction circuit 155, and the suction hole 156 may be used. In these cases, the workpiece W and the molded product M can be held with a thin configuration.

  The work processing unit Uw has the same configuration as that of the first embodiment with respect to the preprocessing unit 16 and the postprocessing unit 17. Also in the work processing unit Uw shown in the present embodiment, for example, as shown in FIG. 10, the first processing unit 18 and the second processing unit 19 may be arranged separately.

  Next, an example of the molding operation of the resin molding apparatus will be described with reference to FIGS. As an example, the workpiece W is assumed to be a round workpiece (semiconductor wafer, carrier) having a chip mounted on the surface, and the operation in the workpiece processing unit Uw is basically the same. Therefore, it demonstrates, referring each figure in 1st Embodiment. First, the robot conveyance device 15 conveys the workpiece W before molding to the workpiece storage unit 13 to the pretreatment unit 16 (see FIG. 4). In this operation, first, the hand main body 151 is inserted into the work accommodating portion 13 to hold the work W.

  Here, the holding | maintenance operation | work of the workpiece | work W using the robot hand 15a shown to FIG. 15 (A) (B) is demonstrated. First, the hand main body 151 is inserted so as to overlap the work W accommodated in the slit magazine in the work accommodating portion 13 shown in FIG. Specifically, the hand main body 151 is inserted to a position where the diameter-enlarged portion of the fixed claw portion 152 is slightly advanced so as not to contact the workpiece W when the workpiece W to be described later is attracted. Next, the hand main body 151 is raised to approach the back surface (chip non-mounting surface) of the work W, and the hand main body 151 is moved to a height at which the enlarged diameter portion of the fixed claw portion 152 exceeds the surface of the work W. Subsequently, the work W is sandwiched between the fixed claw part 152 and the movable claw part 153 by pressing the movable claw part 153 so as to approach the work W (fixed claw part 152) by the claw driving mechanism 154. In this case, the fixed claw portion 152 and the enlarged claw portion of the movable claw portion 153 are arranged at positions where the workpiece W is overlapped with the workpiece W in plan view, so that the workpiece W is mechanically formed by the fixed claw portion 152 and the movable claw portion 153. The workpiece W is securely held (see FIGS. 15A and 15B).

  Subsequently, the back surface of the work W is sucked from the suction hole 156 through the suction circuit 155 by a decompression device (not shown) connected to the robot transport device 15, thereby being sucked at a plurality of positions of the work W. Is retained. Here, by providing the pad portion 157 made of an elastic body, it is possible to prevent the suction failure of the workpiece W.

  The workpiece W thus held is conveyed to the preprocessing unit 16 while being held by the robot hand 15a. In the pre-processing unit 16, predetermined processing is performed, but the workpiece W is in a state in which the semiconductor chip mounting surface faces upward as in the case where the workpiece W is accommodated in the magazine.

  Next, the robot transport device 15 receives the workpiece W from the preprocessing unit 16, and delivers the inverted workpiece W to the delivery unit 2c (see FIG. 13). Thereby, the delivery operation | work of the workpiece | work W of the robot hand 15a is completed. In this way, since the delivery operation of the workpiece W in the delivery unit 2c can be completed without waiting for the arrival of the workpiece hand 4, the waiting time of the robot hand 15a becomes unnecessary, and the other workpiece W and the molded product M are transported. Can do. In addition, the operation | movement which cancels | releases holding | maintenance of the workpiece | work W using the robot hand 15a can be implemented by performing the holding | maintenance operation | work of the workpiece | work W reversely.

  At this time, the robot transport device 15 rotates the robot hand 15a holding the workpiece W by 180 degrees in the circumferential direction Dr of the arm 15e, and changes the posture so that the semiconductor chip mounting surface is directed downward. At this time, since the workpiece W is mechanically held by the fixed claw portion 152 and the movable claw portion 153, even if the workpiece W is not sufficiently held due to insufficient adsorption, the workpiece W is surely dropped. Can be prevented. Specifically, the distance between these four fulcrums is smaller than the diameter of the workpiece W due to the two fixed claw portions 152 and the movable claw portions 153 provided, and even if the robot hand 15a is tilted, the workpiece is viewed from the side. It is possible to prevent W from falling off and falling off. Further, since the back surface of the workpiece W is sucked and held, if the mechanical holding force by the fixed claw portion 152 and the movable claw portion 153 is insufficient, the robot hand 15a is tilted and the workpiece W is tilted. Even if the posture is easy to drop off, the workpiece W is attracted and held at a plurality of locations, so that the workpiece W can be reliably prevented from falling off.

  Subsequently, the work loader 1 moves to a position where the work hand 4 overlaps the delivery unit 2c. Next, the work hand 4 relatively approaches the delivery unit 2c in the ascending / descending direction to hold and receive the work W.

  On the other hand, the preprocessing operation of the workpiece processing unit Uw and the resin supply operation in the resin supply unit Ud are performed in parallel. That is, the resin supply operation is performed in a superimposed manner in the resin supply unit Ud while the pre-processing operation and the like are performed in the work processing unit Uw. Specifically, the roll film 10a provided below the apparatus of the second resin supply unit 11 is guided upward via the guide roller 10f, and the film is supplied to the resin mounting unit 10c. Here, in the film cutout portion 10b, the film edge is drawn out from the roll film 10a, and is cut (cut) into a rectangular shape of an arbitrary size, and cut out on the resin mounting portion 10c as a sheet film F. The remaining amount sensor 10g detects the remaining amount of the roll film 10a provided below the apparatus, and displays a notification according to the remaining amount (replacement time, unusable) on the display unit. For this reason, the operator does not need to visually confirm the lower part of the apparatus in order to confirm the film remaining amount of the roll film 10a.

  In addition, the roll film 10a provided below the apparatus of the 2nd resin supply part 11 is replaced | exchanged at arbitrary timings after the notification in a display part is given. In this case, the front cover (not shown) of the second resin supply unit 11 is opened, the roll film 10a (film roll) having no remaining amount is removed, and the unused roll film 10a is set. Here, the end of the roll film 10a is pulled out and set while passing through the guide roller 10f, and reaches the resin mounting portion 10c. Thus, according to the 2nd resin supply part 11 in this embodiment, the roll film 10a can be replaced | exchanged from the front side of the 2nd resin supply part 11, and the same surface as other operations, such as operation of press part P1, P2. Because it is possible to access from, it is excellent in workability and operability. Moreover, since the syringe supply part 11c is a structure which can be raised / lowered, when replacing | exchanging the roll film 10a, as shown to FIG. 14 (A), the syringe supply part 11c is raised, roll film 10a and guidance The roller 10f can be positioned so as to be easily accessible. Moreover, you may provide the protective cover 10h which covers the upper direction of the roll film 10a, and can be removed only at the time of replacement | exchange.

  On the other hand, in the second resin supply unit 11, the dispenser 11f that discharges the resin R from the syringe 11b is moved in the XYZ directions by the dispenser drive mechanism 11g, so that the single-sheet film F cut out on the resin mounting unit 10c Then, the resin R is mounted (applied) in an arbitrary shape.

  As the resin R for compression-molding the round workpiece W such as the semiconductor wafer of this embodiment, it is preferable to apply (supply), for example, spirally (or concentrically). Specifically, the dispenser drive mechanism 11g controls the position of the dispenser 11f in the XY direction (front-rear direction in the horizontal direction) to move the dispenser 11f from the inside to the outside (or from the outside to the inside) along the spiral trajectory. Let At this time, the piston inserted into the syringe 11b is lowered by a predetermined amount, and the resin R is discharged from the nozzle of the dispenser 11f by a predetermined amount. Thereby, the spirally-shaped resin R is applied to the sheet film F. When stopping the discharge of the resin R from the nozzle (liquid draining), the tube of the nozzle is sandwiched between pinch valves and the discharge path of the resin R is closed to stop the discharge. An operation of rotating the syringe 11b can also be performed so as to follow the outer periphery of the supply region. Further, the resin R hanging from the nozzle may be forcibly drained by a configuration such as a shutter that closes the lower part of the nozzle.

Here, with reference to FIG. 14 (A) (B), the operation | movement of replacement | exchange of the syringe 11b with respect to the dispenser 11f and the operation | movement of replacement | exchange of the syringe 11b with respect to the syringe supply part 11c are demonstrated.
Since the syringe 11b is filled with a predetermined amount of the liquid resin R, it is necessary to receive the dispenser 11f from the unused syringe 11b held in the syringe supply unit 11c every time the molding is performed a predetermined number of times. In this case, first, the syringe supply unit 11c moves up and down to a height position where the syringe 11b can be delivered to the dispenser 11f. That is, as shown in FIG. 14B, the height of the syringe 11b held by the syringe supply unit 11c and the height of the syringe 11b held by the dispenser 11f are set to the same height. Next, the dispenser 11f approaches the syringe supply unit 11c by the dispenser driving mechanism 11g, and delivers the used syringe 11b with no resin R remaining to the syringe supply unit 11c. Subsequently, the syringe supply unit 11c rotates the unused syringe 11b to a position facing the dispenser 11f by the revolver structure. Next, the dispenser 11f approaches the syringe supply unit 11c by the dispenser drive mechanism 11g, and receives an unused syringe 11b from the syringe supply unit. By such an operation, the operation of exchanging the syringe 11b with respect to the dispenser 11f is completed. Subsequently, the resin R can be supplied without waste by supplying the shortage with respect to the total amount to which the resin R is to be applied from the new syringe 11b.

  On the other hand, a plurality of (for example, eight) syringes 11b can be held in the syringe supply unit, but when all of the syringes 11b held in the syringe supply unit 11c are used by repeating the above operation, The operation | movement (operation | work) of replacement | exchange of the syringe 11b with respect to the syringe supply part 11c is needed. In this case, first, the syringe supply part 11c is lowered to a position below the position shown in FIG. 14B, for example, so that the operator moves the syringe supply part 11c up and down to a height at which the syringe 11b can be easily set. Next, the operator opens the front cover (not shown) of the second resin supply unit 11 to expose the syringe supply unit 11c. Subsequently, the used syringe 11b is replaced with an unused syringe 11b while rotating the revolver structure. When the replacement of the syringe 11b is completed, the front cover of the second resin supply unit 11 is closed, and the replacement of the syringe 11b with respect to the syringe supply unit 11c is completed.

  In the replacement operation (work) of these syringes 11b, the syringe supply unit 11c can be moved up and down to an arbitrary position, so that it can be moved to a position corresponding to each replacement operation. Further, as described above, when replacing the roll film 10a, the syringe supply unit 11c can be raised as shown in FIG. 14A so as not to hinder the work. In addition to these replacement operations, when a steady operation of discharging the resin R from the syringe 11b is performed, the syringe supply unit 11c is raised to the position of FIG. By moving from the front of the part 10c, the worker's field of view can be secured and the application shape of the resin R by the dispenser 11f can be visually recognized from the outside of the second resin supply part 11 (for example, a front cover provided with a transparent part). It may be.

  By the way, as operation | movement performed in the work loader 1 as mold operation | movement continuously, the work loader 1 which delivered the workpiece | work W moves to the position which faces the 1st press part P1 along the rail 2a. The hand drive unit 5 does not rotate as in the first embodiment, and the mold die in which the first press part P1 is opened on the linear motion rail 5a provided with the work hand 4 on the hand drive unit 5. Enter toward 21. The workpiece W held by the workpiece holding portion 4b of the workpiece hand 4 is delivered after being aligned with the clamp surface of the upper mold 23. Specifically, the workpiece hand 4 is lifted with respect to the upper clamp surface, and the surface of the workpiece W on which the semiconductor element is not mounted is pressed against and held by the upper clamp surface provided with the suction holes. (See FIG. 2). Next, the work hand 4 that has entered the mold 21 is retracted onto the hand drive unit 5, and the work loader 1 is moved to the work processing unit Uw side along the rail 2a to stand by.

  On the other hand, the resin loader 6 waiting on the rail 2b provided in the second resin supply unit 11 moves on the linear motion rail 9a and enters the resin mounting unit 10c. For example, the resin R is delivered to the resin loader 6 by gripping the opposite sides of the conveying jig 12 with the jig holding portion 8b such as a claw of the sheet film F supplied with the resin R. The resin hand 8 holding the resin R and the sheet film F via the conveying jig 12 is retracted from the resin mounting portion 10 c onto the hand driving portion 9.

  In this state, the resin supply operation by the resin loader 6 is started. The resin loader 6 is moved along the rail 2b to a position facing the first press portion P1. The resin loader 6 moves the resin hand 8 provided on the hand drive unit 9 along the linear motion rail 9a to enter the first press part P1 that is opened. Then, the jig holding portion 8b aligns the conveying jig 12 and the lower mold 29 and lowers the resin hand 8 to release the chuck of the sheet film F by the conveying jig 12, and the lower mold clamping surface and lower By adsorbing and holding in the mold cavity, the resin R together with the sheet film F is delivered to the lower mold 29. In addition, about the shaping | molding operation | movement of the workpiece | work W in this 1st press part P1 and the 2nd press part P2, since it is the same as that of 1st Embodiment, description is abbreviate | omitted.

  The resin loader 6 that has handed over the sheet film F and the resin R is retracted from the first press part P1 onto the hand driving part 9 while the resin hand 8 holds the conveying jig 12. With the resin hand 8 returned to the hand drive unit 9, the resin loader 6 moves the resin loader body 7 again to the second resin supply unit 11 side along the rail 2b. While the resin molding operation is being performed in the first press portion P1, the operation of supplying the workpiece W, the single wafer film F, and the resin R to the second press portion P2 is performed. Since this is the same as the supply operation, the description is omitted here.

  Subsequently, in the first press part P1, the mold 21 is opened, and the molded product M after compression molding is received by the work loader 1 waiting at a position facing the first press part P1, and used. The sheet film F is collected. Next, the work loader 1 is moved to the work processing unit side end (the back position of the film collection unit 17a). Here, the work loader 1 moves to a position where the work hand 4 overlaps the delivery unit 2c. Subsequently, the work hand 4 approaches relatively to the delivery part 2c and delivers the molded product M. Subsequently, the work loader 1 puts the used single-wafer film F sucked on the suction pad 4c into a collection box provided in the film collection unit 17a. Subsequently, the upside down robot hand 15a approaches the delivery unit 2c and receives the molded product M. Thus, since the robot hand 15a can receive the molded product M without waiting for the work loader 1 (work hand 4), other workpieces W and the molded product M can be transported smoothly.

  Next, in the robot transport device 15 that has received the molded product M, the robot hand 15a holding the molded product M is rotated 180 degrees in the circumferential direction Dr of the arm 15e so that the semiconductor chip mounting surface is directed upward from below. Change posture. Since the robot hand 15a has the above-described configuration, it is possible to reliably prevent the molded product M from dropping off at this time as in the case of rotating the workpiece W. Further, since the molded product M is heavier than the workpiece W, for example, if the molded product M is held and reversed with a hand having only an adsorption function, the molded product M is likely to drop off. Further, in the molded product M, warpage may occur due to the heat shrinkage depending on the material of the resin R, and there is a case where it is difficult to reliably hold the molded product M only by adsorption. However, according to the robot hand 15a of the present invention, the suction pad 4c securely holds the back surface of the molded product M while pressing and holding the molded product M on the surface with the diameter-enlarged portions of the fixed claw portion 152 and the movable claw portion 153. The suction state at the suction hole 156 is ensured to prevent the molded product M from falling off (see FIGS. 15A and 15B).

  Next, the molded product M is delivered to the post-processing unit 17 by the robot hand 15a, and post-processing is performed. Subsequently, the molded product M is transferred from the post-processing unit 17 to the molded product storage unit 14 by the robot hand 15a, and the molded product M is stored, and the molding process for one workpiece W is completed. In addition, although the molding process with respect to the workpiece | work W using the 2nd press part P2 is also performed sequentially, since the operation | movement is the same as the operation | movement in the 1st press part P1, description here is abbreviate | omitted.

  As described above, the area of the entire apparatus is reduced in each part of the apparatus, and the installation area can be prevented from becoming longer in the longitudinal direction, and can be arranged compactly while ensuring workability and operability. it can. That is, the robot transport device 15 has a configuration in which the posture is changed by rotating the robot hand 15a holding the workpiece W or the molded product M, so that a separate configuration for changing the posture of the workpiece W or the molded product M is unnecessary. An installation area for the function can be eliminated. Further, the roll resin container 10A and the syringe supply part 11c are provided in the second resin supply part 11 so as to overlap each other so that the roll film 10a and the syringe 11b can be exchanged from the front of the apparatus. The area can be reduced.

  Further, the resin mold apparatus in the present embodiment includes a press unit Up in which press parts P1 and P2 for clamping the work W and the resin R and resin molding are arranged, a work accommodating part 13 for accommodating the work W, and a resin mold A molded product housing portion 14 for housing a molded product M, which is a workpiece W after molding, processing units 16 and 17 for performing pre-processing for the workpiece W or post-processing for the molded product W before and after resin molding, and a housing portion. And a workpiece processing unit Uw having a robot transfer device 15 which is a horizontal multi-indirect robot for transferring the workpiece W or the molded product M to and from the processing unit. The resin molding apparatus includes a work loader 1 that moves forward and backward with respect to the press unit Up to deliver the workpiece W and the molded product M, a conveyance area in which the work loader 1 conveys the workpiece W or the molded product M, and robot conveyance. The apparatus 15 is also provided with a delivery unit 2c that temporarily holds the workpiece W or the molded product M in a region that overlaps with the conveyance region in which the workpiece W or the molded product M is transported.

  According to such a configuration, the plurality of workpieces W and the molded product M can be efficiently transferred without causing the robot transfer device 15 and the work loader 1 to wait.

  Further, the resin mold apparatus in the present embodiment is provided in a press unit Up in which a plurality of press portions P1 and P2 are provided adjacent to each other and in a region adjacent to any of the plurality of press units Up. A transport unit C that transports the work loader 1 in a direction orthogonal to the advancing / retreating direction, a delivery unit 2c on one end side of the transport unit C, and a work processing unit Uw connected to the one end side of the transport unit C. It is the composition which is. Thereby, although it is the structure which can convey the workpiece | work W and the molded article M efficiently, the installation number of press part P1, P2 can be increased arbitrarily, using the delivery part 2c together. Moreover, the effect similar to the effect in embodiment mentioned above can also be show | played by installing the resin unit Ur in the other end side in the conveyance part C as needed.

  Further, as a modified example of the resin molding apparatus capable of reducing the installation area, a configuration as shown in FIG. 16 may be adopted. The resin mold apparatus as a modification shown in the figure has a simple structure by rearranging each unit structure in the resin mold apparatus in the second embodiment and adding a function in the unit.

  Specifically, the resin molding apparatus in the present modification includes a resin supply unit Ud in a press unit Up in which a function is added / converted to the press unit Up in the second embodiment, and a work processing unit Uw in the second embodiment. Is provided with a work processing unit Uw that integrates a part of the functions. For this reason, the apparatus part of the resin supply unit Ud is reduced and the installation area is made compact.

  Specifically, as shown in FIG. 17, the press unit Up in the present modification is provided with a feeding shaft 201 and a winding shaft 202 of the roll film 10 a facing each other with the mold die 21 interposed therebetween, and a film F Is provided with a film handler 204 that performs resin molding in a state where the outer diameter circular cavity 203 (mold surface) is covered with the film F by passing the mold surface from the shaft 201 to the winding shaft 202 while passing the mold surface. . The mold according to this modification can be said to be an “upper cavity type” mold configuration in which the configuration of the mold mold 21 shown in FIG. For this reason, in this modified example, as shown in FIG. 17, the resin R is supplied to the lower mold 29 while being supplied onto the workpiece W.

  For this reason, the work processing unit Uw in this modification has a configuration in which a supply device for the liquid resin R is provided in the work processing unit Uw, as shown in FIG. In other words, the work processing unit Uw and the resin supply unit Ud are integrated. Thus, the workpiece processing unit Uw includes a resin supply unit 16a that supplies the resin R onto the workpiece W as a pre-processing of the workpiece W.

  The resin supply unit 16a has a function equivalent to that of the second resin supply unit 11 in the second embodiment in that the object can be supplied to the object to be coated, although the target is different between the single wafer film F and the workpiece W. For this reason, the resin supply unit 16a can be configured to omit the mechanism related to the roll film 10a. For example, the resin supply unit 16a includes a revolver-type syringe supply unit 11c that holds a plurality of syringes 11b rotatably at a position close to the side surface of the apparatus, a dispenser 11f that holds the syringe 11b and discharges the resin R, and a dispenser 11f. Can be configured to include a dispenser drive mechanism 11g that moves the XYZ in the XYZ directions (front and rear, left and right, up and down directions) (see FIG. 14).

  In the workpiece processing unit Uw in the present modification, the robot hand 15a receives the workpiece W whose orientation is uniformly aligned by, for example, the aligner as the preprocessing unit 16 in the molding operation described in the second embodiment, and the resin R It is conveyed to a resin supply unit (resin supply device) that performs supply.

  Here, the dispenser 11f discharges the liquid resin R onto the work W while moving the syringe 11b so that the locus of the nozzle follows a predetermined shape. For example, the resin R can be supplied to a substantially circular region by discharging and applying the resin R along the spiral trajectory on the workpiece W. In this case, when the width of the application path of the resin R applied is smaller than the resin R, the resin R can be supplied without exposing the surface of the workpiece W in the resin R supply region.

  In this case, the resin R may be supplied to a substantially circular region by starting application from the center of the workpiece W and moving the dispenser 11f so as to move the nozzle of the syringe 11b outward along the spiral trajectory. . By adopting the application (supply) method for applying the resin R in this way, the operation of discharging the resin R from the syringe 11 may be continued until the supply of a predetermined amount of resin is completed, and the resin R can be easily supplied. Can do.

  For example, a method may be adopted in which the dispenser 11f is moved so as to start application from the outer periphery of the workpiece W and move the nozzle of the syringe 11b inward along the spiral trajectory. Therefore, it is necessary to precisely control set values such as the viscosity of the resin R, the total supply amount of the resin R, the area of the region where the resin R is supplied, or the operation amount of the piston with respect to the syringe 11b. It is likely to be difficult to control the uniform supply to the entire surface. For this reason, for example, if the set value is not appropriate, the resin R is insufficient in the center of the area of the region where the resin R is supplied, which may cause a problem of unfilling. For this reason, an application method is preferred in which application starts from the center of the workpiece W and moves the dispenser 11f so as to move the nozzle of the syringe 11b outward along the spiral trajectory. In consideration of reliably applying the resin R to the center of the workpiece W, the dispenser 11f may discharge and supply the liquid resin R to the center position of the workpiece W without moving the syringe 11b.

  Subsequently, the robot hand 15a receives the workpiece W supplied with the resin R and delivers it to the workpiece loader 1 via the delivery unit 2c. Next, the work loader 1 delivers the work W to the upper surface of the lower mold 29 of the mold 21 as shown in FIG. In this modification, since the resin R is supplied onto the workpiece W, the workpiece W is not reversed.

  Here, as the mold 21 of this modification, as shown in FIG. 17, it can be set as the structure which can be pressure-reduced. Specifically, in the mold die 21 of this modification, the lower die 29 is provided with a seal ring 205 that faces the upper die clamper 208 and surrounds the work W mounting area. . Thereby, when the upper mold 23 and the lower mold 29 are closed, a sealed space is formed inside the seal ring 205. In addition, a decompression device 207 is provided for decompressing the sealed space through a suction hole 206 opened in an area surrounded by the seal ring 205 outside the work W mounting area.

  In this case, if the entire amount of liquid resin R is applied to the center position of the workpiece W, the resin R is thickly supplied to the central portion of the workpiece W. For this reason, in the decompression space of the mold 21, air and gas (air etc.) are attracted to the outside by the decompression from the resin R thus supplied. At this time, air or the like gathers while flowing in the resin R and becomes large air or the like and is discharged from the resin R. Therefore, when the air or the like is discharged from the resin R, the resin R on the surface greatly corrugates. It will deform into a non-uniform shape. For this reason, when the resin R is filled in the outer circular cavity 203 in the molding process, the timing at which the resin R reaches the cavity outer periphery (filling timing) is different, and the cavity outer periphery (that is, the molded product M) There is a risk of causing problems such as unfilling and resin leakage on the outer periphery).

  On the other hand, when performing molding using the workpiece W in which the liquid resin R is thinly supplied in a spiral shape as described above, air or the like is supplied from the resin R thus supplied in the decompression space of the mold die 21. Even if the resin R is attracted to the outside due to the reduced pressure, the inside of the resin R does not flow and the air is discharged as a small air and the like, so that the shape of the resin R is hardly deformed. By making the filling timing uniform, it is possible to prevent the occurrence of problems such as unfilling and resin leakage in the cavity outer periphery (that is, the molded product M), and high-quality molding becomes possible.

  Subsequently, the molded product M is transported by the work loader 1 and the robot transport device 15, is post-processed by the post-processing unit 17, and then accommodated in the molded product housing unit 14. Since the operation is performed, the description here is omitted.

  As described above, in the resin molding apparatus according to the present modification, by providing the resin supply unit 16a in the work processing unit Uw instead of the resin supply unit Ud, the effects and advantages of the configuration and method shown as the present modification can be achieved. Not only can this be done, but the resin supply unit Ud is unnecessary, and the installation area can be made compact.

  The configurations of the above-described embodiments and modifications can be used in any combination according to the purpose and application of the apparatus. That is, in the above-described configuration examples, the configuration examples according to the respective purposes are shown in order to explain the invention whose main purpose is to reduce the installation area. However, for example, both “liquid resin R” and “granular resin R” can be selectively used or used together, and any of the mold configurations of “upper cavity type” and “lower cavity type” Can also be used selectively or in combination. In this case, for example, in the resin molding apparatus of the second embodiment shown in FIG. 13, the press sections P1 and P2 are switched to the press sections P1 and P2 including the modified film handler 204 shown in FIG. 16, the resin supply unit 16a in the modification shown in FIG. According to this, it is possible to replace the members of the related parts (mold die 21 and work hand 4 etc.) as appropriate, or to make the function non-use and perform a large-scale response such as rearrangement or addition in units. Further, it is possible to carry out molding by combining these resins R and cavity types.
