Description

  The present invention relates to a mounting apparatus and a mounting method.

  Conventionally, as a mounting device, at the start of production, the tray base is temporarily retracted backward from the component suction position, the obstacle that can be placed at the component suction position is detected by a sensor, and the tray base is in a normal state where no obstacle is detected. Has been proposed in which the production is started by returning it to the suction position (see, for example, Patent Document 1). In this mounting apparatus, it is possible to appropriately inspect an obstacle present at the component suction position. Also, the height of the component already mounted on the board is read, and the angle at which the XY table on which the board is placed can be moved is determined at this height, and the motor is driven when the cam positioner detects this angle. The one that moves the XY table has been proposed (see, for example, Patent Document 2). In this mounting apparatus, the time required for positioning the substrate can be increased without interference between the mounted component and the nozzle.

  In the mounting apparatus described above, for example, there is a case where a component is placed on a tray, and a suction head performs a mounting process of sucking the component from the tray and mounting it on the substrate. In addition, for example, a plurality of nozzle holders having different sizes (heights) with different numbers of nozzles for sucking components may be mounted on the suction head, and the mounting process may be executed. In addition, parts placed on the tray may be large in size or high in height. In such a case, for example, when a component housed other than the tray is mounted, the tray, the component on the tray, and the suction head may interfere with each other such as contact. However, in the mounting apparatuses described in Patent Documents 1 and 2 described above, such a point is not taken into consideration, and the efficiency of the mounting process may not be good.

  The present invention has been made in view of such a problem, and a main object of the present invention is to provide a mounting apparatus and a mounting method capable of performing component mounting processing more efficiently and more reliably.

That is, the mounting apparatus of the present invention is
An acquisition means for acquiring component information including information on the tray and head information including information on a suction head that sucks the component;
Determining means for determining whether the suction head interferes with the tray and / or the component placed on the tray based on the component information and the head information;
A setting means for setting a predetermined standby position where the tray and / or a component placed on the tray and the suction head do not interfere with each other when the determination result interferes with the tray position;
It is equipped with.

  In this mounting apparatus, component information including information related to the tray and head information including information related to the suction head that sucks the component are acquired, and the tray and / or the tray is placed based on the acquired component information and head information. It is determined whether or not the manufactured component interferes with the suction head. When it is determined that interference occurs, a predetermined standby position where the tray and / or the component placed on the tray and the suction head do not interfere is set as the tray position. For example, parts placed on a tray are often relatively large in size or high in height. Here, the position of the tray is set according to whether or not the suction head and the component placed on the tray interfere with each other. Therefore, the contact between the suction head, the tray, and the components placed thereon can be further suppressed, and the component mounting process can be executed more efficiently and more reliably. At this time, when the determination unit determines whether to interfere based on the component information and the head information, the tray and / or the upper area of the component placed on the tray based on the component information It may be determined whether or not the lower area of the suction head based on the head information overlaps, and the interference is determined when it is determined that they overlap.

  Here, the “information about the tray” is, for example, at least one of tray type information, tray size information including the height of the tray, and component size information including the height of the component placed on the tray. May be included. “Suction head information” includes, for example, head size information including the height of the suction head, type information of the member mounted on the suction head, member size information including the height of the member mounted on the suction head, In addition, at least one of the information on the height at the time of movement of the suction head may be included. The term “interference” refers to the case where the suction head and / or the article attached thereto and the tray and / or the components placed on the tray come into contact with each other, the suction head and / or the article attached thereto, and the tray. And / or a case where there is a possibility of contact with a component placed on the tray. The articles attached to the suction head include, for example, a member attached to the suction head, a component that is sucked by the suction head, and the like. The “mounting process” includes a process of placing, mounting, inserting, joining, and adhering components on a substrate.

  In the mounting apparatus of the present invention, the suction head is set to suction the components placed on the tray after the suction processing of the components accommodated in the reel, and the setting means It is good also as what sets the said tray position when performing the adsorption | suction process of the accommodated components. For example, a part accommodated in a reel may be smaller in size or lower in height than a part placed on a tray. For this reason, depending on the position of the tray, when the suction head is moved so as to suck the components housed in the reel, the suction head may interfere with the tray or the components placed on the tray. Here, since the tray position is set when picking up the components housed in the reel before mounting the components on the tray, it is possible to smoothly switch to mounting the components on the tray, and more efficiently Therefore, the component mounting process can be executed more reliably. At this time, the determination means determines whether or not the suction head and the tray and / or the component placed on the tray interfere with each other when suction processing of the component accommodated in the reel is performed. It is good. Further, the suction head may have a lower height for sucking a component accommodated in the reel than a height for sucking the component placed on the tray. In this way, when the reel parts are sucked, interference between the tray and the sucking head is likely to occur, and the significance of applying the present invention is high.

  In the mounting apparatus according to the aspect of the invention, the setting unit may set, as the tray position, a suction position where the suction head sucks the component when the determination result does not interfere. In this way, since the tray is arranged at the suction position, the suction head can immediately pick up the components placed on the tray, and more efficiently and more reliably execute the component mounting process. it can.

  In the mounting apparatus of the present invention, the standby position may be a predetermined position between an initial position of the tray and a suction position where the suction head sucks the component, or an initial position of the tray. For example, when the tray is arranged at a predetermined position that is closer to the suction position than the initial position, the tray can be moved to the suction position earlier when there is interference due to the above determination, so that the efficiency is higher. Further, when the tray is arranged at the initial position, the processing can be simplified.

  In the mounting apparatus of the present invention, the suction head is mounted by switching between a first nozzle holder and a second nozzle holder having a height different from that of the first nozzle holder. The component is picked up using a nozzle holder, and the determination unit determines whether the interference occurs using the head information including information on the first nozzle holder and information on the second nozzle holder. It is good also as what to do. For example, when the nozzle holders having different heights are switched and mounted, the suction head and the tray may or may not interfere with each other, so that it is more meaningful to employ the present invention. Further, interference can be determined using information on the first nozzle holder and information on the second nozzle holder. Here, the “nozzle holder information” may include, for example, at least one of nozzle holder type information, size information including the height of the nozzle holder, and the like. At this time, the determination means may determine that the interference occurs when a higher nozzle holder is attached. Further, the determination means may determine that the interference occurs when a predetermined nozzle holding body is mounted on the suction head among the first nozzle holding body and the second nozzle holding body. In this way, for example, by checking in advance the relationship regarding the interference between the tray and the nozzle holder, it is possible to determine whether or not the interference occurs according to the type of the nozzle holder that is mounted, and the determination process Can be made easier.

  In the mounting apparatus of the present invention, the head information includes information on the height of the component sucked by the suction head, and the determination means includes the height of the component sucked by the suction head. In addition, it may be determined whether or not the interference occurs. In this way, it is possible to execute the component mounting process more efficiently and more reliably in consideration of the height of the component sucked by the suction head.

  The mounting apparatus according to the present invention includes a suction head that sucks a component, a head moving unit that moves the suction head, an initial position of the tray on which the component is placed, and a suction position where the suction head sucks the component. It is also possible to include a tray moving unit that moves between the control unit and a control unit that controls the tray moving unit to move the tray to the tray position set by the setting unit.

  In the mounting apparatus of the present invention, the acquisition unit, the determination unit, and the setting unit may determine whether or not to interfere with the acquisition of the information in advance before performing a mounting process for placing a component on a board. The determination and the setting of the tray position may be executed. Alternatively, in the mounting apparatus of the present invention, the acquisition unit, the determination unit, and the setting unit determine whether or not to interfere with the acquisition of the information in advance while performing a mounting process of placing a component on a board. And the setting of the tray position may be executed.

The mounting method of the present invention is:
(A) acquiring component information including information regarding the tray and head information including information regarding a suction head that sucks the component;
(B) determining whether the suction head interferes with the tray and / or the component placed on the tray based on the component information and the head information;
(C) when the determination result interferes, a step of setting a predetermined standby position where the tray and / or the component placed on the tray and the suction head do not interfere with each other as a tray position;
Is included.

  In this mounting method, similar to the mounting apparatus described above, the position of the tray is set according to whether or not the suction head and the component placed on the tray interfere with each other. It is possible to further suppress the contact with the made component, and it is possible to more efficiently and more reliably execute the component mounting process. In this mounting method, various aspects of the mounting device described above may be adopted, and steps for realizing each function of the mounting device described above may be added.

The mounting line 10 is arranged such that the component mounting machines 11a to 11d and 11 that perform the mounting processes of the first to fifth steps are in ascending order from upstream to downstream. The first to fifth steps are all steps for mounting an electronic component (hereinafter referred to as “component”) on the substrate 16. In the present embodiment, the component mounter 11 on which the tray unit 50 and the reel unit 56 are mounted will be described, and the description of the component mounters 11a to 11d will be omitted. The mounting process includes a process of placing, mounting, inserting, joining, and adhering components on a substrate.

  As shown in FIG. 2, the component mounting machine 11 includes a base 12, a mounting machine main body 14 installed on the base 12, a tray unit 50 mounted on the mounting machine main body 14, and a mounting machine main body 14. And a reel unit 56 mounted on the machine.

  The base 12 is a heavy object formed in a rectangular parallelepiped, and casters (not shown) are attached to the four corners of the back surface.

  The mounting machine main body 14 is installed so as to be replaceable with respect to the base 12. The mounting machine body 14 includes a substrate transport device 18 that transports the substrate 16, a suction head 24 that can move in the XY plane, a suction nozzle 40 that is attached to the suction head 24 and can move to the Z axis, and a suction nozzle 40. A side camera 68 that photographs the picked-up components, a nozzle stocker 72 that stocks a plurality of types of suction nozzles that can be attached to the suction head 24, and a control device 74 (see FIG. 5) that executes various controls are provided. Yes.

  The substrate transport device 18 is provided with support plates 20 and 20 provided at intervals in the front and rear direction of FIG. 2 and extending in the left-right direction, and conveyor belts 22 and 22 provided on the mutually opposing surfaces of the support plates 20 and 20 (FIG. 2 shows only one of them). The conveyor belts 22 and 22 are stretched over the drive wheels and the driven wheels provided on the left and right sides of the support plates 20 and 20 so as to be endless. The board | substrate 16 is mounted on the upper surface of a pair of conveyor belts 22 and 22, and is conveyed from the left to the right. The substrate 16 is supported by a large number of support pins 23 erected on the back side.

  The suction head 24 is attached to the front surface of the X-axis slider 26. The X-axis slider 26 is attached to the front surface of the Y-axis slider 30 that can slide in the front-rear direction so as to be slidable in the left-right direction. The Y-axis slider 30 is slidably attached to a pair of left and right guide rails 32, 32 extending in the front-rear direction. The guide rails 32 and 32 are fixed inside the component mounter 11. A pair of upper and lower guide rails 28, 28 extending in the left-right direction are provided on the front surface of the Y-axis slider 30, and the X-axis slider 26 is attached to the guide rails 28, 28 so as to be slidable in the left-right direction. The suction head 24 moves in the left-right direction as the X-axis slider 26 moves in the left-right direction, and moves in the front-rear direction as the Y-axis slider 30 moves in the front-rear direction. The sliders 26 and 30 are driven by drive motors 261 and 301 (see FIG. 5), respectively. The sliders 26 and 30 and the drive motors 261 and 301 constitute a suction head moving unit. The suction head moving unit is set to linearly move the suction head 24 so as to be the shortest distance to the next suction position after the components are arranged on the substrate 16. Thus, since the movement of the suction head 24 is the shortest, the mounting process can be executed more efficiently.

  As shown in FIG. 3, the suction head 24 has a head main body 41 that is detachably mounted on an X-axis slider 26 (head holding base). A nozzle holder 42 is supported on the head body 41 so as to be intermittently rotatable, and is intermittently rotated by a rotating device using a motor 43 as a drive source. A plurality of nozzle holders 44 are held up and down on the circumference of the nozzle holder 42, and suction nozzles 40 that suck parts are detachably held by these nozzle holders 44. The nozzle holder 44 positioned at a predetermined angular position by intermittent rotation of the nozzle holder 42 is moved in the Z-axis direction (vertical direction) perpendicular to the X-axis and Y-axis directions by a holder lifting device using a Z-axis motor 46 as a drive source. The component can be sucked by the suction nozzle 40 and mounted on the substrate 16. Further, the nozzle holder 44 is rotated (spinned) by a holder rotating device using the motor 47 as a drive source, and the angle of the component sucked by the suction nozzle 40 can be adjusted. The component mounter 11 includes a plurality of nozzle holders 42 having different numbers of suction nozzles 40 to be mounted and different heights. During the production, the nozzle holders 42 are switched and mounted on the head main body 41 for mounting. Execute the process. For example, as shown in FIG. 4, the first nozzle holder 42a where the component pickup height is lower than the upper end of the tray 52, or the component pickup height is located above the first nozzle holder 42a. It is assumed that the second nozzle holding body 42b and the third nozzle holding body 42c for picking up the components on the tray 52, which are higher than the upper end of the tray 52, are used. The first to third nozzle holders 42a to 42c are collectively referred to as the nozzle holder 42. The nozzle holder 42 that is not mounted on the suction head 24 is placed on a holder stocker 48 (see FIG. 4). The nozzle holder 42 is formed so that, for example, the height of the nozzle holder 42 to which a large number of suction nozzles 40 can be mounted is higher (the distance to the substrate 16 is shorter). For this reason, the movement time in the Z-axis direction is further shortened, and the mounting process can be executed more efficiently. In addition, the suction head 24 is provided with a side camera 68 for photographing the part sucked by the suction nozzle 40 from the side. The side camera 68 is disposed in the suction head 24 so as to be movable up and down, and has a height at which a part sucked by the suction nozzle 40 can be photographed according to the nozzle holder 42 attached to the suction head 24. Move to and be fixed.

  The suction nozzle 40 uses pressure to suck a component at the tip of the nozzle or to release a component sucked at the tip of the nozzle. As shown in FIG. 2, the suction nozzle 40 is connected to one of a vacuum pump 64 and an air pipe 66 via an electromagnetic valve 62. In order to suck the parts to the suction nozzle 40, the electromagnetic valve 62 is positioned so that the vacuum pump 64 and the suction nozzle 40 communicate with each other. As a result, the inside of the suction nozzle 40 has a negative pressure, and the component is sucked to the tip of the suction nozzle 40. On the other hand, in order to remove the component from the suction nozzle 40, the electromagnetic valve 62 is positioned so that the air pipe 66 and the suction nozzle 40 communicate with each other. As a result, the inside of the suction nozzle 40 becomes a positive pressure, and the part sucked at the tip of the suction nozzle 40 is removed.

  The tray unit 50 includes a magazine cassette (not shown) that houses a plurality of trays 52, a pallet 51 that fixes a desired tray 52 from the magazine cassette that is mounted, a pallet 51 that fixes the tray 52, and a predetermined initial position and suction position. A tray moving unit 54 (see FIG. 5). The tray 52 has a substantially rectangular outer shape using a resin, and has a number of rectangular pockets. Parts are accommodated in the pockets. The components accommodated in the tray 52 are larger in height and size than the components accommodated in the reel 57. Further, the tray 52 is higher than the reel 57. When the tray 52 is used for mounting processing, the tray 52 is attached to the pallet 51 with, for example, a pressing metal or a magnet. When the pallet 51 is pulled out from the magazine cassette by the tray moving unit 54 and disposed at the suction position, the components accommodated in the tray 52 can be sucked by the suction head 24. Here, as shown in FIG. 4, the tray 52 is between the initial position in the magazine cassette, the suction position where the suction head 24 sucks components, and the initial position and the suction position, and does not interfere with the suction head 24. It is placed either at the standby position (which does not touch). This standby position includes tray-side members such as the tray 52 and components placed on the tray 52, components sucked by the suction head 24 and suction nozzle 40, and suction-head-side members such as the side camera 68. Is determined at a position closer to the suction position. Note that “interference” refers to contact between the suction head 24 and an article attached to the suction head 24 (for example, a component sucked by the side camera 68 or the suction nozzle 40) and a component placed on the tray 52 or the tray 52. In addition to the case, the case where there is a possibility that the suction head 24 or an article accompanying the suction head 24 and the component placed on the tray 52 may come into contact with each other is included. This is because the position of the tray 52 may be displaced, and the component sucked by the suction head 24 may be rotated or shifted.

  As shown in FIG. 2, the reel unit 56 includes a plurality of reels 57 and is detachably attached to the front side of the mounting machine body 14. A tape is wound around each reel 57, and parts are held on the surface of the tape along the longitudinal direction. These parts are protected by a film covering the surface of the tape. Such a tape is unwound from the reel toward the rear, and is fed to a suction position where the tape is sucked by the suction head 24 in a state where the film is peeled off at the feeder portion 58 and the components are exposed.

  The nozzle stocker 72 is a box that stocks a plurality of types of suction nozzles 40. The suction nozzle 40 is detachably mounted on the nozzle holder 42 of the suction head 24, and is replaced with one suitable for the type of the board 16 on which the component is mounted and the type of the component.

  As shown in FIG. 5, the control device 74 is configured as a microprocessor centered on a CPU 741, a ROM 742 that stores processing programs, an HDD 743 that stores various data, a RAM 744 that is used as a work area, an external device and an electric device. An input / output interface 745 for exchanging signals is provided, and these are connected via a bus 746. The control device 74 outputs drive signals to the substrate transport device 18, the drive motor 261 of the X-axis slider 26, the drive motor 301 of the Y-axis slider 30, the motors 43, 46, 47 of the suction head 24 and the electromagnetic valve 62. The image signal from the side camera 68 is input. The control device 74 is connected to the tray unit 50, the reel unit 56, and the management computer 80 so as to be capable of bidirectional communication. Each slider 26, 30 is equipped with a position sensor (not shown), and the control device 74 controls the drive motors 261, 301 of each slider 26, 30 while inputting position information from these position sensors. .

  The control device 74 includes an information acquisition unit 747 as a functional block, an interference determination unit 748, and a position setting unit 749. The information acquisition unit 747 executes processing for acquiring component information including the type information of the tray 52 and head information including the type information of the nozzle holder 42 attached to the suction head 24. Here, it is set to acquire the information on the tray 52 as the component information 91 and the information on the nozzle holder attached to the suction head 24 as the head information 92 from the mounting information 90 stored in the HDD 743 ( (See FIG. 6). The interference determination unit 748 executes processing for determining whether or not the suction head side member and the tray side member interfere with each other based on the component information 91 and the head information 92. The position setting unit 749 sets a predetermined standby position as the tray position when the determination result interferes with the suction head side member and the tray side member, whereas when the determination result does not interfere with each other. Processing to set the suction position to the tray position is executed. Note that the position setting unit 749 executes a tray position setting process including a process for sucking the components accommodated in the reel 57.

  Mounting information 90 is stored in the HDD 743. As shown in FIG. 6, the mounting information 90 stores component information 91 that is information related to components, head information 92 that is information related to the suction head 24, and the like as information related to processing for mounting components on the substrate 16. The mounting information 90 also stores tray position information 94 set by the position setting unit 749. The mounting information 90 is managed by the management computer 80, and is transmitted from the management computer 80 to the control device 74 and stored in the HDD 743 based on an operator input to the management computer 80. The component information 91 includes, for example, component type information in the order of mounting processing, component size information including the height of the component, arrangement position information on the board 16, information on a device supplying the component, tray to be used 52 type information and tray size information including the height of the tray 52 are also stored. The head information 92 includes type information of the nozzle holder 42 used when sucking the component, size information including the height of the nozzle holder 42, and the like. The types of the first to third nozzle holders 42a to 42c are the holder Nos. 1-No. This will be described as 3. Further, although not shown, the head information 92 includes type information of the suction nozzle 40 that sucks the component, size information of the suction nozzle 40, and the like. The type information includes a name and an identification number. In the component mounting machine 11, the mounting information 90 is set so that the component placed on the tray 52 is subjected to suction processing after the suction head 24 performs suction processing on the component accommodated in the reel 57. Further, the height of the suction position for sucking the component placed on the tray 52 is higher than the height of the suction position for sucking the component accommodated in the reel 57. For example, since the components housed in the reel 57 are relatively small, the components are placed first from the nozzle holder 42 that is closer to the substrate 16 (the height of the nozzle holder 42 is high) and can be mounted with more suction nozzles 40. It is set to be implemented. By doing so, more components can be mounted by one reciprocating movement of the suction head 24, and the efficiency of the mounting process can be improved, for example, the moving distance of the suction head 24 is shortened.

  As shown in FIG. 5, the management computer 80 is configured as a microprocessor centered on a CPU 801. A ROM 802 that stores processing programs, an HDD 803 that stores various types of information, a RAM 804 that is used as a work area, and an external device and an electrical device. An input / output interface 805 for exchanging signals is provided, and these are connected via a bus 806. Further, the management computer 80 can input signals from an input device 82 typified by a mouse and a keyboard via an input / output interface 805 and is connected to the display 84 so that various images can be output. The HDD 803 stores mounting information including the mounting contents of the board, component information unique to the component, head information regarding an article to be mounted on the suction head 24, and the like. Here, the mounting information is the same information as the mounting information 90 shown in FIG. 6, which component is mounted on the circuit board in each of the component mounters 11 a to 11 d, 11, and is mounted as such. This information includes how many circuit boards are produced. Further, the component information and the head information are the same as the component information 91 and the head information 92 described above.

  Next, the operation of the component mounting system 1 of the present embodiment configured as described above, first, the processing for setting the arrangement position of the tray 52 in the mounting processing of the component mounting machine 11 will be described. FIG. 7 is a flowchart illustrating an example of a tray position setting process routine executed by the CPU 741 of the component mounter 11. This routine is stored in the HDD 743 of the component mounter 11, and is executed by a start instruction from the operator. This routine is a process for setting the first-out process for moving the tray 52 to the suction position as early as possible when the component mounting process of the reel 57 is being executed. This routine is executed by the CPU 741 using the functions of the information acquisition unit 747, the interference determination unit 748, and the position setting unit 749, for example. When this routine is started, the CPU 741 of the component mounter 11 first sets a determination target component for setting the position of the tray 52 (step S100). Here, for example, it is determined that the last component in the mounting order is set as the head, and the first component in the mounting order is set in the last order. When the determination target component is set, the mounting information 90 is read, and the component information 91 and the head information 92 regarding the determination target component are acquired (step S110). Here, information on the type of the tray 52 to be used is acquired from the component information 91, and information on the type of the nozzle holder 42 used when sucking the determination target component is acquired from the head information 92.

  Next, the CPU 741 has a tray-side member such as the tray 52 or a component placed on the tray 52, a component sucked by the suction head 24 or the suction nozzle 40, and a suction head side such as the side camera 68. It is determined whether or not the member interferes (step S120). Here, it is assumed that the suction head side member and the tray side member interfere with each other when the first nozzle holder 42a closest to the substrate 16 is attached to the suction nozzle 40 (see FIG. 4). Further, in the second nozzle holding body 42b in which the suction nozzle 40 is positioned above the first nozzle holding body 42a and the third nozzle holding body 42c in which the suction nozzle 40 is further positioned above, The description will be made on the assumption that the suction head side member and the tray side member do not interfere even if the component is sucked by the suction nozzle 40. In such a case, the interference can be determined by acquiring the type of the tray 52 and the type of the nozzle holder 42. Here, it is determined that there is interference when the suction head 24 is mounted on the first nozzle holder 42a, and it is determined that there is no interference when the other is mounted. It should be noted that a component whose supply device is the tray 52 may be determined to have no interference in step S120. This is because when the suction head 24 sucks components from the tray 52, the suction head side member and the tray side member do not necessarily interfere with each other. When it is determined in step S120 that there is interference, the standby position is set to the tray position when picking up the part to be determined (step S130), and when it is determined that there is no interference, the suction position is set to the tray position (step S130). S140).

  After steps S130 and S140, the CPU 741 determines whether or not the determination process has been completed based on whether or not the above determination has been made for all components (step S150). The processes after step S110 are repeatedly executed. That is, whether or not the suction head side member and the tray side member interfere with each other in the process of setting the next component (the previous component in the mounting order) as the determination target component, and sucking and arranging the component. Determine. Then, the process of setting the position of the tray 52 in the process of sucking and arranging the determination target component is repeatedly performed. On the other hand, when the determination process is finished in step S150, the tray position information 94 is stored in the HDD 743 (step S160), and this routine is finished. Here, this information is stored in the tray position information 94 of the mounting information 90.

  The setting of the tray position will be specifically described with reference to FIGS. 4 and 6. Here, in order from the start of mounting, the components A to D are mounted from the reel 57 by the first nozzle holder 42a, and the components E to H are mounted from the reel 57 by the second nozzle holder 42b. Is set to perform mounting processing from the tray 52 by the third nozzle holder 42c. Prior to execution of this tray position setting processing routine, nothing is stored in the tray position information 94. When the tray position setting processing routine is executed, the component information 91 and the head information 92 are acquired from the mounting information 90, and the determination target component is set. Here, the part L is set as the first determination target part. Then, whether or not the suction head side member and the tray side member interfere with each other is determined based on the type of the nozzle holding body 42 attached to the suction head 24. Since the supply device is the tray unit 50, the component L is determined not to interfere, and the suction position is set to the tray position. Next, the parts K to E are similarly determined, and the suction position is set to the tray position. Subsequently, when the component D is set as the determination target component, the nozzle holding body 42 attached to the suction head 24 is the first nozzle holding body 42a, and the suction head side member and the tray side member interfere with each other. It is determined to do. As a result, the standby position is set to the tray position. Then, the parts C to A are similarly determined, and the standby position is set to the tray position. When the tray position is set in this way, the tray 52 can be advanced in advance during the mounting process with the reel 57, and the process can proceed to the mounting process with the tray 52 without moving the tray 52 as it is. Unlike the above-described case, when the standby position and the suction position are set in a mixed manner, in order to keep the tray 52 from being moved frequently, for example, the last position in the mounting order may be used. What is necessary is just to set so that the tray 52 may be moved to the suction position at the part next to the part set at the standby position (set at the suction position).

  Next, a process for mounting various components on the board 16 using the set tray position will be described. FIG. 8 is a flowchart illustrating an example of a mounting process routine executed by the CPU 741 of the component mounter 11. This routine is stored in the HDD 743 of the component mounter 11, and is executed by a start instruction from the operator. When this routine is started, the CPU 741 first reads the mounting information 90 to acquire the mounting conditions (step S200), and executes the substrate transport and fixing process (step S210). Next, based on the mounting order of the mounting information 90, a component to be suctioned is set (step S220), and the nozzle holder 42 and the suction nozzle 40 corresponding to the component are mounted (step S230). If the suction nozzle 40 and the nozzle holder 42 to be used are already attached to the suction head 24, the process of step S230 is skipped.

  Next, the CPU 741 determines whether or not the tray 52 is at the suction position (step S240). When the tray 52 is not at the suction position, the tray position of this component set in the tray position information 94 is examined (step S240). Step S250). When the set tray position is the standby position, the tray 52 is moved to the standby position (step S260). When the tray 52 is already in the standby position, the tray 52 is set as the standby position as it is. On the other hand, when the set tray position is the suction position, the tray 52 is moved to the suction position (step S270). After step S260 or S270, component pick-up processing and placement processing are performed (step S280), and it is determined whether the current board mounting processing is completed (step S290). In step S280, when the tray 52 is in the standby position, the component suction process is performed from the reel 57. When the tray 52 is in the suction position, the supply device (the tray 52) according to the component set in step S220. Alternatively, the component suction processing is performed from the reel 57).

  When the current board mounting process has not been completed, the CPU 741 executes the processes after step S220. That is, components are mounted one after another on the current board. At this time, after the tray 52 is set to the suction position in step S270, it is determined in step S240 that the tray 52 is in the suction position, and the processes in steps S250 to S270 are omitted. As described above, the mounting process is repeatedly executed while the tray 52 is changed to the initial position, the standby position, and the suction position as set in the tray position information 94. In this way, the tray 52 is moved as close to the suction position as possible without causing interference between the suction head side member and the tray side member, the suction head 24 is moved linearly, and the suction nozzle 40 is further moved up and down. It is possible to execute the mounting process more efficiently with suppression.

  On the other hand, when the mounting process of the current board is completed in step S290, the board 16 that has been mounted is discharged (step S300), the tray 52 is moved to the standby position (step S310), and it is determined whether or not the production is completed. (Step S320). When the production is not completed, the processes after step S210 are repeatedly executed. That is, the process of mounting the components on the board 16 is repeatedly performed while the new board 16 is transported and fixed, and the tray 52 is first advanced. Note that during the repetition of this process, if there are no more parts on the tray 52, the mounting process is executed while switching to the new tray 52 as appropriate. On the other hand, when the production is completed in step S320, this routine is finished as it is.

  Here, the correspondence between the components of the present embodiment and the components of the present invention will be clarified. The information acquisition unit 747 of this embodiment corresponds to the acquisition unit of the present invention, the interference determination unit 748 corresponds to the determination unit, and the position setting unit 749 corresponds to the setting unit. The suction head 24 corresponds to the suction head, the X-axis slider 26, the Y-axis slider 30, and the Z-axis motor 46 correspond to the head moving unit, the tray moving unit 54 corresponds to the tray moving unit, and the control device 74 It corresponds to the control means. Further, the component information 91 corresponds to the component information, and the head information 92 corresponds to the head information. In the present embodiment, an example of the mounting method of the present invention is also clarified by describing the operation of the component mounter 11.

  According to the component mounter 11 described above, the component information 91 including information regarding the tray 52 and the head information 92 including information regarding the suction head 24 are acquired, and based on the acquired component information 91 and the head information 92. It is determined whether or not the tray side member and the suction head side member interfere with each other. When it is determined that interference occurs, a predetermined standby position where the tray-side member and the suction head-side member do not interfere is set as the tray position. For example, the parts placed on the tray 52 are often relatively large in size or high in height. Here, the position of the tray 52 is set according to whether or not the suction head 24 and the component placed on the tray 52 interfere with each other. Therefore, the contact between the suction head side member and the tray side member can be further suppressed, and the component mounting process can be executed more efficiently and more reliably.

  Further, the suction head 24 is set so as to suction the components placed on the tray 52 after the suction processing of the components contained in the reel 57, and the position setting unit 749 Sets the tray position when performing the suction process. For example, the part accommodated in the reel 57 may be smaller in size or lower in height than the part placed on the tray 52. For this reason, depending on the position of the tray 52, if the suction head 24 is moved so as to suck the components housed in the reel 57, the member on the suction head side may interfere with the member on the tray side. Here, by setting the tray position when performing the adsorption process of the component accommodated in the reel 57, the component mounting process can be executed more efficiently and more reliably.

  Furthermore, if the determination result does not interfere, the suction position at which the suction head 24 sucks the component is set as the tray position, so the suction head 24 can immediately suck the component placed on the tray 52, The component mounting process can be executed more efficiently and reliably. Furthermore, the standby position is a position between the initial position of the tray 52 and the suction position where the suction head 24 picks up the components, that is, a position closer to the suction position than the initial position. It can move and is more efficient. And in order to determine whether it interferes using the head information 92 containing the information of the 1st-3rd nozzle holding body 42a-42c from which height differs, for example, switching and mounting the nozzle holding body from which height differs In doing so, the suction head 24 and the tray 52 may or may not interfere with each other, and the significance of employing the present invention is higher. Moreover, it can be determined whether it interferes using the information of the 1st-3rd nozzle holding body 42a-42c. Further, since it is determined that the suction head side member and the tray side member interfere with each other when the predetermined third nozzle holding body 42c is attached to the suction head 24, the determination process is performed relatively easily. can do. Still further, the information acquisition unit 747, the interference determination unit 748, and the position setting unit 749 acquire the component information 91 and the head information 92 before performing the mounting process of placing the component on the board 16, and the suction head side. Since the determination whether or not the member on the tray side and the member on the tray side interfere with each other and the setting of the tray position are executed in advance, the first-out point of the tray 52 can be determined in advance.

  It should be noted that the present invention is not limited to the above-described embodiment, and it goes without saying that the present invention can be implemented in various modes as long as it belongs to the technical scope of the present invention.

  For example, in the above-described embodiment, the type of the tray 52 is acquired as the component information 91. However, the present invention is not particularly limited thereto. For example, the size information of the tray including the height of the tray 52 is used as the component information 91. Also, at least one of the component size information including the height of the component placed on the tray 52 may be acquired. Further, although the type of the nozzle holder 42 is acquired as the head information 92, the present invention is not limited to this. For example, the size information including the height of the suction head 24, the type information of the member mounted on the suction head 24, the size information of the member including the height of the member mounted on the suction head, and the height when the suction head is moved It is good also as what acquires at least 1 among the information regarding thickness. The component information 91 and the head information 92 acquired by the information acquisition unit 747 are not particularly limited as long as the information can determine whether or not the suction head side member and the tray side member interfere with each other.

  For example, a case will be described in which it is determined whether the suction head side member and the tray side member interfere with each other using the height of the tray 52 or the height of the nozzle holder 42. FIG. 9 is a flowchart showing an example of another tray position setting processing routine. Here, the same steps as those in the tray position setting processing routine described above are denoted by the same step numbers, and description thereof is omitted. When this routine is started, the CPU 741 of the component mounter 11 first sets a determination target component in step S100, reads the mounting information 90, and acquires component information 91 and head information 92 related to the determination target component (step S100). S410). Here, information on the height of the tray 52 and information on the height of the component placed on the tray are acquired from the component information 91. Further, from the head information 92, information on the height of the nozzle holder 42 used when sucking the determination target component, information on the height of the suction nozzle 40, information on the height of the determination target component, and the like are acquired. . Next, the height of the member on the suction head side is calculated from the height of the determination target component, the height of the nozzle holder 42, the height of the suction nozzle 40, and the like (step S420). The height of the member on the tray side is calculated from the information on the height of the component placed on the tray (step S430). Here, as shown in FIG. 4A, an extension surface of the surface of the circuit board 16 fixed to the substrate transfer device 18 is used as a reference surface, and the height from the reference surface, for example, the height of the tray 52 is used. Ht, the height Hp of the component Pt on the tray, the height Hn to the lower surface of the component Ph sucked by the suction head 24, and the like are obtained. The height Hn can be obtained from the position of the mounting surface of the nozzle holder 42, the height of the nozzle holder 42, the height of the suction nozzle 40, and the height of the component Ph to be sucked. In step S120, it is determined whether or not the tray-side member and the suction head-side member interfere with each other. In this determination, it is determined whether or not the upper region of the tray side member and the lower region of the suction head side member overlap with each other based on whether or not the height Hn is lower than the heights Ht and Hp. It is determined that these interfere with each other. In addition, since the position of the tray 52 and the components may be attracted to the suction nozzle 40 while being displaced or rotated, the “upper region of the member on the tray side” and the “lower part of the member on the suction head side” More preferably, the “range” includes a predetermined margin. This margin may be determined empirically at the time of mounting by taking the state of the upper area of the tray side member and the lower area of the suction head side member as data. When it is determined in step S120 that there is interference, in step S130, the standby position is set to the tray position for picking up the part to be determined. On the other hand, when it is determined that there is no interference, in step S140, the suction position is set to the tray position. Set to. In step S150, it is determined whether the determination process has been completed. In step S160, the tray position information 94 is stored in the HDD 743, and this routine ends. Even in this case, as in the above-described embodiment, the contact between the suction head side member and the tray side member can be further suppressed, and the component mounting process can be executed more efficiently and reliably. In addition, taking into account the height of the component sucked by the suction head 24, the component mounting process can be executed more efficiently and more reliably. Here, it is determined whether or not the suction head side member and the tray side member interfere with each other, including the height of the component Ph attracted to the suction head 24. However, the height of the suctioned component Ph is determined as follows. It may be omitted to determine whether or not the suction head side member and the tray side member interfere with each other.

  In the above-described embodiment, it is determined that the component placed on the tray 52 is suctioned after the component accommodated in the reel 57 is sucked. However, the present invention is not limited to this. For example, the components may be sucked from the reel 57 after sucking the components from the tray 52. Further, the components may be alternately sucked from the tray 52 and the reel 57. Even in this case, when the member on the suction head side and the member on the tray side interfere with each other, the tray 52 is positioned at the standby position, so that the contact between the member on the suction head side and the member on the tray side can be further suppressed. The component mounting process can be executed more efficiently and reliably.

  In the above-described embodiment, the standby position of the tray 52 is set between the suction position of the tray 52 and the initial position, but is not particularly limited thereto, and may be the initial position of the tray 52, for example. In this case, the tray 52 is moved when switching to suck the components on the tray 52, but interference between the suction head side member and the tray side member can be prevented, so that the component mounting process can be performed more reliably. Can be executed. Further, since the tray is arranged at the initial position, the processing can be simplified.

  In the above-described embodiment, the component mounting process is executed by switching the first to third nozzle holders 42a to 42c having different heights, but the present invention is not particularly limited thereto. For example, as long as the reels 57 and the tray 52 have different suction heights, the invention is not particularly limited to switching the plurality of nozzle holders 42.

  In the above-described embodiment, the information acquisition unit 747, the interference determination unit 748, and the position setting unit 749 of the control device 74 of the component mounter 11 set the tray position of the tray position information 94. For example, the management computer 80 may include an information acquisition unit, an interference determination unit, and a position setting unit, and these may set the tray position of the tray position information. That is, the apparatus for setting the tray position and the apparatus for executing the mounting process may be separated. At this time, the tray position information set by the management computer 80 may be transmitted to the control device 74. Even in this case, the same effect as the above-described embodiment can be obtained.

  In the above-described embodiment, the tray position in each component is set in the tray position information 94. However, the present invention is not limited to this. For example, the movement timing for moving the tray 52 from the standby position to the suction position is set. It may be a thing. For example, in the above-described embodiment, since the circuit board 16 and the tip of the suction nozzle 40 are set so as to be mounted and mounted in order from the nozzle holder 42, the tray 52 is mounted during the mounting process of one board. There is no reciprocal movement between the standby position and the suction position. In such a case, the movement timing (part E in FIG. 4) to the suction position may be set. In addition, if the tray position in each component is set as in the above-described embodiment, the tray 52 can be moved according to the component to be sucked.

  In the above-described embodiment, the mounting information 90 stores the component information 91, the head information 92, and the tray position information 94, but may be stored separately.

  In the embodiment described above, in step S100, the last component in the mounting order is set as the initial value, and the tray position is set in the order in which the first component in the mounting order is the last. However, the present invention is not limited to this. For example, the first component in the mounting order may be set as the initial value, and the last component in the mounting order may be set in the last order. Even in this case, the tray position can be set.

  In the above-described embodiment, the control device 74 has been described as controlling the tray unit 50 and the reel unit 56. However, the tray unit 50 and the reel unit 56 include a control device, and these control devices serve as the tray moving unit 54 and the feeder. The unit 58 may be controlled.

  In the above-described embodiment, the tray position of the tray position information 94 is set in advance by the control device 74 before executing the mounting process. However, the present invention is not limited to this. For example, the position of the tray 52 may be set while performing the mounting process, and the tray 52 may be moved to the set tray position. In the above-described embodiment, the mounting process is performed in a state where the tray 52 is in the suction position after the tray 52 is advanced. However, the present invention is not particularly limited to this, and for example, the tray 52 according to the component to be mounted. The mounting process may be performed while moving the position to the standby position or the suction position.

  In the above-described embodiment, the component mounting machine 11 as the mounting apparatus of the present invention has been described. However, the present invention is not particularly limited thereto, and a mounting method or a program form thereof may be used.

  The present invention can be used in the technical field of mounting components on a board.
