According to the present invention, the resin material can be supplied at multiple locations.

Hereinafter, the directions shown by arrow U, arrow D, arrow F, arrow B, arrow L, and arrow R in the figure are defined as up, down, front, back, left, and right directions, respectively. .

First, the structure of the resin molding apparatus 1 of this embodiment is demonstrated using FIG. 1. FIG. The resin molding apparatus 1 resin-encapsulates electronic components such as semiconductor chips to manufacture a resin molded product. Particularly in this embodiment, the resin molding apparatus 1 adopting a compression molding method (compression method) in which a resin material in a cavity is compressed and molded is exemplified.

The resin molding apparatus 1 includes a substrate carry-in/out module 10, a substrate transfer module 20, a molding module 30, a resin supply module 40, and a control unit 50 as structural elements. Each structural element can be detached from other structural elements and can be replaced.

The board carry-in and carry-out module 10 carries in the substrate P on which the electronic components are mounted, and carries out the substrate P in which the electronic components are sealed with a resin. In this embodiment, it is assumed that a relatively large substrate P is used. For example, the substrate P is formed in a rectangular plate shape whose one side is 450 mm or more, 500 mm or more, or 600 mm or more. The board carry-in and carry-out module 10 mainly includes: a carry-in part 11, a carry-out part 12, an inspection part 13 and an arm mechanism 14.

The carrying-in part 11 is a part where the board|substrate P which is not resin sealed is arrange|positioned. The carrying-out part 12 is a part where the board|substrate P sealed with resin is arrange|positioned. The carrying-in part 11 and the carrying-out part 12 can accommodate a plurality of substrates P, respectively.

The inspection part 13 is a part that performs inspection of the resin-sealed substrate P. The inspection part 13 includes a mounting part on which the resin-sealed substrate P is mounted, an inspection mechanism (not shown) that inspects the substrate P, and the like.

The arm mechanism 14 moves the substrate P. The arm mechanism 14 includes a suction hand 14a for sucking the substrate P, an arm 14b for attaching the suction hand 14a, a driving unit 14c for rotating or moving the arm 14b appropriately, and the like.

The substrate transfer module 20 is a part that performs transfer of the substrate P between the substrate carry-in/out module 10 and the molding module 30 described later. The substrate transfer module 20 mainly includes a loader 21 and an unloader 22.

The loader 21 receives the substrate P that is not resin-sealed from the arm mechanism 14 and conveys it to the molding die 31 of the molding module 30 described later. The unloader 22 receives the resin-sealed substrate P from the molding die 31 described later, and conveys it to the substrate carry-in/out module 10. The loader 21 and the unloader 22 are movable along guide rails La extending in the left-right direction. In this embodiment, the loader 21 and the unloader 22 are connected to each other so as to move integrally.

The molding module 30 uses a resin material supplied from a resin supply module 40 described later to resin-seal the electronic components mounted on the substrate P. In this embodiment, two forming modules 30 are arranged side by side. By using the two molding modules 30 to perform resin sealing of the substrate P in parallel, the production efficiency of the resin molded product can be improved. The forming module 30 mainly includes a forming die 31 and the like.

The molding die 31 compresses and molds the substrate P using a molten resin material. The forming mold 31 includes a pair of upper and lower molds (an upper mold and a lower mold). A concave cavity (not shown) for accommodating the resin material is formed in the lower mold. In addition, a heater (not shown) for melting the resin material is provided in the forming mold 31.

The resin supply module 40 supplies the resin material to the molding die 31 of the molding module 30. The resin supply module 40 mainly includes: a resin supply mechanism 100, a small tray 41, a small tray transport mechanism 42, a large tray 43, and a large tray transport mechanism 44.

The resin supply mechanism 100 supplies a resin material to a small tray 41 described later. The resin supply mechanism 100 can supply the resin material to the two small trays 41 in parallel. In addition, the detailed structure of the resin supply mechanism 100 will be described later.

The small tray 41 supplies the resin material received from the resin supply mechanism 100 to the large tray 43 described later. The small tray 41 can hold a resin material on the upper surface. The small tray 41 is formed so that the size in a plan view becomes about a quarter of the size of the large tray 43 described later.

The small tray transport mechanism 42 transports the small tray 41 to an appropriate position. The small tray transport mechanism 42 can transport the small tray 41 between the resin supply mechanism 100 and the large tray 43 in such a manner that the small tray 41 reciprocates.

The large tray 43 supplies the resin material received from the small tray 41 to the molding die 31 of the molding module 30. The large tray 43 can hold the resin material on the upper surface. The large tray 43 is formed so as to have a planar shape (for example, a rectangular shape) corresponding to the planar shape of the cavity of the forming mold 31.

The large tray transport mechanism 44 transports the large tray 43 to an appropriate position. The large tray transport mechanism 44 can move along a guide rail La extending in the left-right direction. Here, a supplementary description is given to the small tray 41 and the large tray 43. The so-called "tray" herein may be used as long as the resin material in the form of particles can be stored therein, and the resin material storage portion may be single or multiple. For example, as a tray, a structure may be adopted in which the resin material storage portion is divided into a plurality of regions, and the resin material contained in the plurality of resin material storage portions is dropped using a shutter mechanism provided below. In addition, as the pallet, a structure may be adopted in which a plurality of cylindrical members that are partially open along the longitudinal direction and are hollowed out are arranged side by side in a single direction, so that the plurality of cylindrical members are arranged side by side in a single direction. Each member rotates to drop the resin material contained in the internal space of the cylindrical member.

The control unit 50 controls the operation of each module of the resin molding apparatus 1. The control unit 50 controls the operations of the board carry-in/out module 10, the board transfer module 20, the molding module 30, and the resin supply module 40. In addition, the operation of each module can be arbitrarily changed (adjusted) using the control unit 50.

Next, the outline of the operation (the molding method of the resin molded product) of the resin molding apparatus 1 configured as described above will be described.

First, the substrate P that is not resin-sealed and arranged in the carry-in section 11 is transported to the loader 21 by the arm mechanism 14.

Next, the loader 21 moves along the guide rail La to transport the substrate P to one of the forming modules 30. The substrate P conveyed to the forming module 30 is sucked and held by the upper mold of the forming mold 31.

Next, a release film is arranged so as to cover the lower mold of the forming mold 31.

Next, the resin material is supplied from the resin supply module 40 to the molding die 31 of the molding module 30. Here, in the resin supply module 40, the resin material previously supplied from the resin supply mechanism 100 is supplied to the large tray 43 via the small tray 41. Since the small tray 41 is formed to be about a quarter of the size of the large tray 43, a total of four small trays 41 are used to supply the resin material to the entire large tray 43 substantially uniformly.

By moving the large tray transport mechanism 44 along the guide rail La, the large tray 43 holding the resin material is transported to the molding die 31 of the molding module 30. After that, the resin material of the large tray 43 is supplied to the cavity of the forming mold 31 (lower mold). After the large tray transport mechanism 44 supplies the resin material to the molding die 31, it returns to the resin supply module 40.

Next, the resin material is melted by the heater of the forming mold 31. After that, in a state where the lower mold and the upper mold are close to each other and the electronic components of the substrate P are immersed in the resin material, pressure is appropriately applied to the resin material. By hardening the resin material in this state, a substrate P in which electronic parts are sealed with resin can be obtained.

Next, the unloader 22 moves along the guide rail La, and receives the resin-sealed substrate P of the electronic parts from the molding die 31. At this time, the new substrate P can be placed on the forming mold 31 by the loader 21 that moves together with the unloader 22. After that, the unloader 22 moves along the guide rail La and returns to the substrate transfer module 20.

Next, the substrate P held by the unloader 22 is transported to the inspection unit 13 by the arm mechanism 14. In the inspection part 13, the inspection of the board|substrate P whose electronic components are resin-sealed is performed.

Then, the substrate P after the inspection is conveyed to the unloading unit 12 by the arm mechanism 14. The board|substrate P arrange|positioned in the carrying-out part 12 is suitably carried out to the outside.

As described above, by resin-sealing the electronic components mounted on the substrate P, a resin molded product can be manufactured. In addition, although the description is omitted in the description of the operation described above, in the resin molding apparatus 1 of the present embodiment, the resin sealing of the substrate P can be performed in parallel by using the two molding modules 30 provided. Specifically, when one of the molding modules 30 is used for resin sealing (melting of the resin material, pressing against the substrate P, etc.), the other molding module 30 may be supplied with a resin material or the substrate P may be resin-sealed. In this way, it is possible to efficiently manufacture a resin molded product (a substrate P in which an electronic component is sealed with a resin).

Hereinafter, the resin supply mechanism 100 of the resin supply module 40 will be specifically described using FIGS. 2 to 11.

The resin supply mechanism 100 mainly includes: a frame 110, a container storage unit 120, a lifting mechanism 130, a rotating mechanism 140, a lateral movement mechanism 150, a lid opening mechanism 160, a resin storage unit 170, a dust collecting mechanism 180, a container recovery unit 190, and an air conditioner装置200。 Device 200.

The frame body 110 shown in FIG. 2 accommodates each part (container storage part 120 etc. mentioned later) which comprises the resin supply mechanism 100. The frame body 110 is formed into a box shape having an appropriate shape by an appropriate frame, wall surface, or the like. By accommodating the container storage portion 120 and the like in the housing 110, it is possible to prevent dust such as powder of the resin material from leaking to the outside of the resin supply mechanism 100, and to prevent contamination of the external air.

The container storage unit 120 shown in (d) of FIGS. 2 to 4 is a part that stores the container C for storing the resin material. The container C is formed in a substantially cylindrical shape having a bottom (for example, refer to Fig. 5(a), Fig. 5(b), etc.). The opening formed at one end of the longitudinal direction of the container C is closed by the cap C1. In this embodiment, it is assumed that a pelletized resin material is used, and the resin material is stored in the container C in a predetermined amount. Furthermore, as the resin material, not only granular materials but also materials in any form such as powder or liquid can be used. The container storage portion 120 mainly includes: a side wall 121, an inclined surface 122, a lower stopper 123 and an upper stopper 124.

The side wall 121 restricts the movement of the container C in the left-right direction. The side wall 121 is provided with a pair of left and right so as to face each other. The interval between the pair of left and right side walls 121 is formed to be approximately the same as the diameter of the container C.

The inclined surface 122 is used to guide the container C carried out from the container storage unit 120. The inclined surface 122 is arranged so as to be inclined toward the lower left from the lower end of one of the side walls 121 (the right side wall 121 in this embodiment).

The lower stopper 123 restricts the dropping of the container C. The lower stopper 123 is provided near the lower end of one of the side walls 121 (the right side wall 121 in this embodiment). A slit is provided on the side wall 121 so that the lower stopper 123 can protrude toward the container C. The lower stopper 123 can be expanded and contracted by an appropriate actuator (for example, an air cylinder, etc.). The lower stopper 123 is entirely located on the right side of the side wall 121 in a state of being contracted by the action of the actuator. In addition, when the lower stopper 123 is extended by the action of the actuator, the front end (left end) protrudes to the left from the side wall 121.

The upper stopper 124 restricts the dropping of the container C. The upper stopper 124 is arranged above the lower stopper 123. The upper stopper 124 and the lower stopper 123 are arranged at a predetermined interval (an interval substantially the same as the diameter of the container C). The structure of the upper stopper 124 is the same as that of the lower stopper 123. That is, when the upper stopper 124 extends, the front end (left end) protrudes from the side wall 121 to the left.

In addition, in the normal time (a state where the container C is stored in the container storage unit 120), only the lower stopper 123 is extended, and the upper stopper 124 is contracted (see FIG. 4(a)). That is, it is in a state where only the lower stopper 123 protrudes to the left of the side wall 121.

In the container storage unit 120 configured as described above, a plurality of containers C can be stored. Specifically, an appropriate door provided in the housing 110 is opened by the operator, and the container C is arranged between the pair of side walls 121. At this time, the container C is arranged in a state where the longitudinal direction faces the lateral direction (front and rear) (more specifically, the state where the lid C1 faces the front). The container C tries to move (fall down) downward between the pair of side walls 121 due to its own weight, but the movement of the container C is restricted by the lower stopper 123 (see FIG. 4(a)). Thus, the container C can be held between the pair of side walls 121. In addition, by arranging the containers C to be stacked up and down, a plurality of containers C can be stored in the container storage unit 120.

In addition, the container storage unit 120 can carry out the containers C one by one to the elevating mechanism 130 described later as needed. Specifically, as shown in FIG. 4(b), first, the upper stopper 124 is extended, and the downward movement of the second container C from the bottom is restricted. Next, as shown in FIG. 4(c), the lower stopper 123 contracts, and the restriction of the lowermost container C is released. As a result, the lowermost container C moves downward due to its own weight, rolls on the upper surface of the inclined surface 122, and is guided to the elevating mechanism 130 arranged on the left. Finally, as shown in FIG. 4(d), the lower stopper 123 is extended, and the upper stopper 124 is contracted. As a result, the container C remaining in the container storage unit 120 moves downward.

The elevating mechanism 130 shown in FIGS. 2 to 4(d) raises and lowers the container C carried out from the container storage unit 120. The lifting mechanism 130 mainly includes: a placing part 131, a guide rail 132, a moving part 133 and a motor 134.

The motor 134 is a member (drive source) that generates driving force for moving the moving part 133 up and down. The motor 134 is connected to the moving part 133 via an appropriate power transmission mechanism. By controlling the movement (rotation direction, rotation speed, etc.) of the motor 134, the moving part 133 (and even the placing part 131) can be moved up and down to an arbitrary position.

The rotation mechanism 140 shown in FIGS. 2, 3, and 5(a) and 5(b) holds the container C and rotates it in a predetermined direction. The rotating mechanism 140 mainly includes a motor 141, a base portion 142, and a grip portion 143.

The motor 141 shown in FIGS. 5( a) and 5 (b) is a member (drive source) that generates a driving force for rotating the base portion 142 described later. The motor 141 is arranged such that the output shaft (not shown) faces to the right.

The base part 142 is a part which supports the grip part 143 mentioned later. The left end of the base portion 142 is connected to the output shaft of the motor 141. Thereby, the base portion 142 can rotate together with the output shaft of the motor 141.

The grip portion 143 is a part that grips the container C. The holding part 143 is provided with a pair of left and right. The grip portion 143 is provided so as to be able to move left and right with respect to the base portion 142. The grip 143 can be moved left and right by the driving force of an appropriate actuator (not shown).

The rotation mechanism 140 configured as described above is supported by the lateral movement mechanism 150 described later. As shown in FIG. 8(a), in a state where the container C is arranged between a pair of left and right grip portions 143, the grip portion 143 can be used to sandwich the container C by moving the grip portions 143 close to each other. To keep. By driving the motor 141 in this state, the container C can be rotated in any direction. For example, in (b) of FIG. 8, a state where the lid C1 of the container C is rotated in a face-up manner is shown.

The lateral movement mechanism 150 shown in FIGS. 2, 5(a), 5(b), and FIG. 6 moves the container C in the lateral direction (left-right direction). The lateral movement mechanism 150 mainly includes: a guide rail 151, a moving part 152 and a motor 153.

The guide rail 151 shown in FIG. 5(a), FIG. 5(b), and FIG. 6 guides the moving part 152 so that the moving part 152 mentioned later can move in a lateral direction (horizontal direction). The guide rail 151 is formed of an appropriate member extending in the left-right direction. The guide rail 151 is arranged so as to extend to the left from above the elevating mechanism 130 (near the upper end of the guide rail 132).

The moving part 152 is a part provided so as to be able to move left and right with respect to the guide rail 151 (the longitudinal direction of the guide rail 151). A rotating mechanism 140 is provided in the moving part 152.

The motor 153 is a member (drive source) that generates driving force for moving the moving part 152 left and right. The motor 153 is connected to the moving part 152 via an appropriate power transmission mechanism. By controlling the action (rotation direction, rotation speed, etc.) of the motor 153, the moving part 152 (and even the rotating mechanism 140) can be moved left and right to any position. In addition, for convenience, illustration of the motor 153 is omitted in FIG. 5(b).

The lid opening mechanism 160 shown in FIGS. 2, 5 (a ), 5 (b ), and FIG. 6 opens the lid C1 of the container C. The lid opening mechanism 160 is arranged above the lifting mechanism 130 (upper side than the rotation mechanism 140 and the lateral movement mechanism 150). The lid opening mechanism 160 mainly includes a motor 161, a grip portion 162 and a lifting cylinder 163.

The motor 161 shown in FIG. 5(a), FIG. 5(b), and FIG. 6 is a member (drive source) which generates the driving force for rotating the grip part 162 mentioned later. The motor 161 is arranged such that the output shaft 161a faces downward.

The grip portion 162 is a part that grips the lid C1 of the container C. A plurality of grips 162 are provided at the lower end of the output shaft 161a of the motor 161. The grip 162 is provided to be able to swing with respect to the output shaft 161a. The grip portion 162 can be arbitrarily swung by an appropriate actuator (for example, an air cylinder, etc.). The lid C1 of the container C can be grasped by swinging the lower end portions of the plurality of grasping portions 162 so as to approach each other.

The lift cylinder 163 shown in FIG. 5(b) is used to move the motor 161 up and down (lifting). The lift cylinder 163 is arranged so as to be able to expand and contract up and down. The lift cylinder 163 is connected to the motor 161. By expanding and contracting the lifting cylinder 163, the motor 161 can be raised and lowered.

With the lid opening mechanism 160 configured as described above, the lid C1 of the container C can be opened. Specifically, when the cap C1 is removed from the container C, as shown in FIG. 8(c), the motor is driven in a state where the cap C1 of the container C held by the rotating mechanism 140 is gripped by the gripping portion 162 161. As a result, the cap C1 can be rotated relative to the container C. Along with this, by gradually raising the motor 161 by the lift cylinder 163, as shown in FIG. 8(d), the cap C1 can be removed from the container C. As shown in FIG.

In addition, when the cap C1 is attached to the container C, as shown in FIG. 8( e ), the motor 161 is driven in a state in which the removed cap C1 is grasped by the grasping portion 162. In this state, by gradually lowering the motor 161 by the lift cylinder 163, the cap C1 can be attached to the container C held by the rotation mechanism 140.

The resin storage section 170 shown in FIGS. 2, 6, 7( a ), and 7 (b) is a part that temporarily stores the resin material supplied from the container C to the small tray 41. A plurality of resin storage parts 170 are provided along the guide rail 151 of the lateral movement mechanism 150 (two in this embodiment). Furthermore, FIG. 7(a) and FIG. 7(b) show a state where the right resin storage portion 170 of the two resin storage portions 170 is viewed from the right (right side view). The resin storage part 170 mainly includes a guide part 171, a stocker 172, a first feeder 173, a resin supply part 174, and a second feeder 175.

The guide part 171 shown in FIGS. 6 and 7(a) and 7(b) is a part that guides the resin material discharged from the container C to a hopper 172 described later. The guide portion 171 is formed in a cylindrical shape that is open up and down. The guide portion 171 is formed in a substantially funnel shape that is narrower than the upper portion at the lower portion.

The stocker 172 temporarily holds the resin material discharged from the container C, and supplies it to the resin supply part 174 mentioned later. The stocker 172 is formed in a substantially box shape with an upper opening. A supply port (not shown) for supplying the stored resin material downward (resin supply unit 174) is formed at the bottom of the stocker 172. The stocker 172 is provided with a sensor 172a.

The sensor 172a is used to detect whether a predetermined amount of resin material is stored in the stocker 172. The sensor 172a may be constituted by, for example, a reflective photoelectric sensor, but may also be constituted by a transmissive sensor.

The first feeder 173 is used to discharge the resin material from the hopper 172. The first feeder 173 is arranged at the lower part of the hopper 172, and can make the hopper 172 vibrate.

The second feeder 175 is used to discharge the resin material from the resin supply part 174. The second feeder 175 is provided at the lower part of the resin supply part 174 and can vibrate the resin supply part 174. By vibrating the resin supply part 174 by the second feeder 175, the resin material can be gradually dropped from the supply port of the resin supply part 174 and supplied to the small tray 41 arranged below (see FIG. 1).

The resin accommodating portion 170 configured as described above accommodates the resin material, and the resin material can be appropriately supplied to the small tray 41. Specifically, the resin material supplied from the container C is stored in the stocker 172. To the resin supply unit 174, the resin material is appropriately supplied from the stocker 172 based on the detection value of the weight sensor so as to always store a predetermined amount of resin material. The resin material contained in the resin supply unit 174 is supplied to the small tray 41 at an appropriate timing. In addition, when the sensor 172a detects that the resin material contained in the stocker 172 has decreased, as described later, the resin material of the container C is supplied to the stocker 172.

The dust collecting mechanism 180 shown in FIGS. 2 and 3 collects dust such as powder of resin material by sucking the air in the housing 110. The dust collection mechanism 180 mainly includes a main body 181, a suction port 182 and a hose 183.

The main body 181 shown in FIG. 3 is a unit formed by a fan for sucking air, a filter for collecting dust, and the like. The main body 181 is arranged at an appropriate portion of the housing 110.

The hose 183 connects the main body 181 and the suction port 182. The hose 183 is appropriately branched and connected to a plurality of suction ports 182 respectively.

The container recovery part 190 shown in FIGS. 2 and 3 is a part that recovers the container C that has been emptied by supplying the resin material to the resin storage part 170. The container recovery part 190 mainly includes a recovery box 191 and an inclined surface 192.

The collection box 191 shown in FIG. 3 accommodates the empty container C. The recovery box 191 is formed in a substantially box shape with an upper opening. The collection box 191 is arranged below the container storage unit 120.

The inclined surface 192 guides the container C to the recovery box 191. The inclined surface 192 is arranged at the lower left of the inclined surface 122 of the container storage unit 120. The inclined surface 192 is arranged so as to be inclined from the upper left end of the collection box 191 toward the upper left. The inclined surface 192 is arranged in the middle part (lower part) of the path in which the mounting part 131 of the lifting mechanism 130 is raised and lowered. The inclined surface 192 is formed with a slit (not shown) through which the mounting portion 131 of the elevating mechanism 130 can pass up and down.

The air conditioner 200 shown in FIGS. 2 and 3 adjusts the temperature or humidity in the housing 110. The air conditioner 200 mainly includes a main body 201 and a hose 202.

The main body 201 shown in FIG. 3 performs air cooling and dehumidification. In FIG. 3, the main body 201 is arranged outside the housing 110, but the hose 202 may be included, and the entire air conditioner 200 is arranged inside the housing 110. The main body 201 can introduce air from the outside of the housing 110 to appropriately perform cooling and dehumidification.

The hose 202 guides the air cooled and dehumidified by the main body 201 into the housing 110. The hose 202 is connected to appropriate parts of the main body 201 and the frame 110, respectively. By supplying the cooled and dehumidified air to the housing 110 through the hose 202, the temperature or humidity in the housing 110 can be appropriately adjusted.

Next, the operation of the resin supply mechanism 100 configured as described above (specifically, the operation of supplying the resin material contained in the container C to the resin storage portion 170) will be described.

When the sensor 172a provided in the stocker 172 detects that the resin material in the stocker 172 has decreased to some extent (the resin material contained in the stocker 172 is less than a predetermined amount), the container is started The resin material stored in C is supplied to the resin storage section 170. In addition, the following description of the operation assumes that the resin material in the hopper 172 of the resin storage portion 170 on the right side of the two resin storage portions 170 is reduced.

First, as shown in FIG. 3, one of the stored containers C (the lowermost container C) is carried out to the elevating mechanism 130 by the container storage unit 120. The container C carried out to the elevating mechanism 130 is placed in the concave portion 131 a of the placing portion 131.

Next, as shown in FIGS. 3 and 6, the container C is lifted by the lift mechanism 130 and is arranged in the lifted position that can be held by the rotation mechanism 140. In this state, the container C is held by the rotation mechanism 140 (refer to FIG. 8(a)), and the cover C1 is rotated in a face-up manner (refer to FIG. 8(b)).

Next, as shown in FIGS. 8( c) and 8 (d ), the lid C1 of the container C is opened by the lid opening mechanism 160.

Next, as shown in FIG. 9, the lateral movement mechanism 150 is used to move the rotation mechanism 140 (even the container C) to the left. In addition, based on the start timing of the movement of the container C by the lateral movement mechanism 150, the dust collection mechanism 180 is operated. Here, when the container C is started to be moved by the lateral movement mechanism 150, the fan of the main body 181 is operated, and suction from the suction port 182 is started. By operating the dust collecting mechanism 180, dust and the like from the opened container C can be sucked. The container C is stopped at a position (resin supply position) where the resin material can be supplied to the resin storage section 170. Specifically, the container C stops at a position overlapping with the resin storage portion 170 (guide portion 171) on the right side when viewed from the front. Furthermore, the start of the operation of the dust collection mechanism 180 can be advanced/delayed by a certain time relative to the start timing of the movement of the container C by the lateral movement mechanism 150 based on the start timing of the movement of the container C by the lateral movement mechanism 150. control.

Next, as shown in FIG. 7( b ), the container C is rotated by the rotation mechanism 140. Thereby, the opening part of the container C faces downward, and the resin material in the container C is supplied to the stocker 172 via the guide part 171.

When a predetermined time elapses with the container C facing downward, the opening of the container C faces upward again by the rotation mechanism 140.

Furthermore, the resin material in the container C is supplied to the stocker 172, and when it is detected by the sensor 172a that a predetermined amount of resin material is accommodated in the stocker 172, the dust collection mechanism 180 stops.

On the other hand, even if the resin material in the container C is supplied to the stocker 172, when the sensor 172a detects that the predetermined amount of resin material is not contained in the stocker 172, the dust collecting mechanism 180 does not Stop and continue to run.

After the opening of the container C faces upward, the container C is moved to the right by the lateral movement mechanism 150. The container C stops immediately below the lid unsealing mechanism 160.

Next, as shown in FIG. 8( e ), the cap C1 of the container C is attached by the cap opening mechanism 160. Furthermore, as shown in (f) of FIG. 8, the container C is rotated laterally (with the lid C1 facing forward) by the rotation mechanism 140.

Next, as shown in FIG. 10, the holding of the container C by the rotation mechanism 140 is released, and the container C is moved downward by the lifting mechanism 130. When the placing portion 131 moves below the inclined surface 192 through the slit of the inclined surface 192, the container C placed on the placing portion 131 is guided by the inclined surface 192 and collected into the collection box 191.

In this way, the supply of the resin material contained in one container C to the resin storage portion 170 is completed. Here, in the case where the resin material in the hopper 172 is still small (when the sensor 172a detects that the predetermined amount of resin material is not accommodated in the hopper 172), then another container The resin material of C is supplied to the stocker 172. In this manner, the supply of the resin material of the container C to the stocker 172 is repeated until a predetermined amount of resin material is stored in the stocker 172. During this period, the dust collection mechanism 180 continues to operate.

In addition, in the operation description, the case where the resin material of the hopper 172 on the right side is reduced is exemplified, but when the resin material of the hopper 172 on the left side is decreased, the resin material of the container C is also supplied in the same manner. In this case, as shown in FIG. 11, the container C is moved by the lateral movement mechanism 150 to a position that overlaps with the resin storage portion 170 (guide portion 171) on the left side when viewed from the front, and the resin material of the container C is supplied to the left side.的stocker 172.

In this way, in this embodiment, the container C can be moved to a plurality of positions (positions corresponding to the left and right resin storage portions 170) by the lateral movement mechanism 150. Thereby, the resin material can be supplied to the resin accommodating part 170 provided in a plurality of places. Since the resin material can be supplied to the small tray 41 in parallel from the plurality of resin storage parts 170 to which the resin material is supplied in the above manner, the production efficiency of the resin molded product can be improved.

In addition, the operation of the dust collection mechanism 180 starts and stops at an appropriate timing. That is, the dust collecting mechanism 180 collects dust intermittently. Thereby, while dust collection is performed, it is possible to prevent the temperature or humidity in the housing 110 adjusted by the air conditioner 200 from being disturbed. Here, the timing of stopping the operation of the dust collecting mechanism 180 can be controlled based on the timing of attaching the lid C1 to the container C after the resin supply by the lid unsealing mechanism 160, or based on the recycling of the container C after the resin supply to the recovery box 191. The internal timing is controlled, or based on the detection by the sensor 172a that a predetermined amount of resin material is stored in the stocker 172.

As described above, the resin supply mechanism 100 of this embodiment includes: The container storage unit 120 stores the container C containing the resin material; The lifting mechanism 130 raises the container C stored in the container storage unit 120 to a predetermined rising position; The lid unsealing mechanism 160 unseales the lid C1 of the container C in the raised position; The lateral movement mechanism 150 moves the container C unsealed by the lid unsealing mechanism 160 in the lateral direction and moves it to any one of a plurality of resin supply positions; and The rotating mechanism 140 rotates the container C located at the resin supply position to discharge the resin material contained in the container C.

By configuring as described above, the resin material can be supplied at a plurality of positions. That is, the lateral movement mechanism 150 can be used to move the container C to a plurality of positions (resin supply positions) to supply the resin material. As a result, the resin material can be supplied to a plurality of locations (in this embodiment, the plurality of resin storage portions 170), and the same manufacturing steps (in this embodiment, the supply of the resin material to the small tray 41) can be performed in parallel. Furthermore, the efficiency of manufacturing can be achieved.

In addition, the resin supply mechanism 100 further includes: The plurality of resin accommodating parts 170 are arranged to correspond to the plurality of resin supply positions, and accommodate the resin material discharged from the container C.

By configuring as described above, the efficiency of manufacturing can be achieved. That is, the resin material supplied to the plurality of resin storage parts 170 can be used to supply the resin material to the small tray 41 in parallel. As a result, the size of the resin molded product (substrate P) is promoted, and even if the resin material required for resin molding increases, it is possible to suppress deterioration in manufacturing efficiency (improve manufacturing efficiency).

In addition, the resin supply mechanism 100 further includes: The container recovery unit 190 recovers the container C after the resin material is discharged.

By configuring as described above, the efficiency of manufacturing can be achieved. In other words, there is no need for the operator to take out the empty container C every time, so that the efficiency of manufacturing can be achieved. In addition, as in the present embodiment, by providing the container recovery part 190 in the housing 110, it is possible to prevent dust and the like from the empty container C from leaking to the outside of the resin supply mechanism 100.

In addition, the resin supply mechanism 100 further includes: The dust collection mechanism 180 collects dust in the space (inside the housing 110) where the container C moves.

By configuring as described above, it is possible to suppress contamination of the air or each part. That is, along with the movement of the container C, the powder of the resin material contained in the container C may be scattered into the frame 110. Therefore, by collecting the dust in the housing 110, the scattered dust can be recovered, and the pollution of the air or each part can be suppressed. In addition, accompanying this, the outflow of dust to the outside of the housing 110 can be suppressed, and therefore, the pollution of the air outside the housing 110 can also be suppressed.

In addition, the dust collecting mechanism 180 collects dust intermittently.

With the configuration as described above, it is possible to prevent the temperature or humidity in the housing 110 from being disturbed while performing dust collection in the housing 110. In particular, as in the present embodiment, when the air conditioner 200 is used to perform air conditioning in the housing 110, the air conditioning in the housing 110 by the air conditioner 200 and the air conditioning in the housing 110 by the dust collecting mechanism 180 can be combined. Dust collection (suppression of contamination in the housing 110).

In addition, the dust collection mechanism 180 starts dust collection based on the timing when the movement of the container C by the lateral movement mechanism 150 is started.

By configuring as described above, dust can be collected efficiently. That is, it is considered that there is a high possibility that the powder of the resin material or the like will scatter from the container C along with the movement of the container C. Therefore, by starting the dust collection mechanism 180 with the movement of the container C, dust collection can be efficiently performed.

In addition, the container storage unit 120 can store a plurality of containers in a state where the longitudinal direction of the container C faces the lateral direction, so as to overlap up and down.

By configuring as described above, more containers C can be stored in a small area. That is, by stacking the container C up and down and storing it, it is possible to reduce the area required for storage (the width of the front and rear and the left and right). In addition, since the longitudinal direction of the container C faces the lateral direction, the height when stacking a plurality of containers C can be suppressed, and therefore more containers C can be stored.

In addition, the resin molding apparatus 1 of this embodiment includes the resin supply mechanism 100 described above.
