The movable portion 84 is movably supported by the movable shaft 82, and its upper end is attached to the lower surface of the table surface 54A of the table 54 (see FIGS. 5 and 6).

  In the table moving mechanism, the table moving belt 86 is wound around the table moving motor 88 and is wound around the rear end portion of the movable shaft 82. When the table moving motor 88 is energized, the movable shaft 82 rotates, The movable portion 84 moves along the movable shaft 82 along the front-rear direction. Thereby, the table 54 fixed to the movable shaft 82 moves in the front-rear direction above the table support portion 56.

  Hereinafter, the position of the table 54 in a state where the movable portion 84 is located at the rear end portion of the movable shaft 82 (state shown in FIG. 6) is referred to as “rear end position BE” (an example of the first position). The position of the table 54 in a state where the movable portion 84 is located at the front end portion of the movable shaft 82 (state shown in FIG. 7) is referred to as “front end position FE” (an example of the second position). As shown in FIG. 7 and the like, the front end position FE is a position farther from the pallet housing part 52 than the table support part 56.

  As described above, in the tray supply device 50, the entire table 54 is moved in the front-rear direction between the rear end position BE and the front end position FE by the table moving mechanism. For this reason, when the whole table 54 moves forward, the dimension in the front-rear direction of the tray supply device 50 increases as a whole. Accordingly, when any device is arranged in front of the tray supply device 50, the table 54 moves forward, so that the tray supply device 50 and the device come close to each other, and the table 54 moves rearward to move the tray. A gap is formed between the supply device 50 and the device.

  The tray supply device 50 configured as described above is arranged in the following manner in the surface mounter 1. In the surface mounting machine 1, each tray supply device 50 is arranged on both sides of the transport conveyor 20 in the moving direction of the table 54 (the pulling direction of the pallet 60 and the moving direction of the hook 55) and the transporting direction of the printed circuit board P by the transporting conveyor 20. Are arranged in such a direction that they are orthogonal to each other.

  By arranging each tray supply device 50 in such a direction, in the tray 62 in each pallet 60 accommodated in the pallet accommodating portion 52, the conveyance direction (X-axis direction) and the direction orthogonal to the conveyance direction (Y The electronic components E are held in a matrix in the component housing portion 63 along the axial direction.

  In the surface mounter 1, the mounting operation of the electronic components E is performed in units of rows along the transport direction of the component housing portion 63 in the tray 62 (hereinafter, the transport direction in which the electronic components E that are the mounting targets are held). The column along the line is referred to as a “mounting target column”). The mounting target column is determined in order from the front side of the tray 62. That is, when the electronic component E to be mounted is held in the foremost row along the conveying direction of the component housing portion 63, the foremost row is set as the mounting target row. When the remaining number of electronic components E in the mounting target column becomes zero, the column one column after that column is set as the next mounting target column.

  As shown in FIG. 1, one (upper side shown in FIG. 1) tray supply device 50 has a front end portion and a reference position of the table 54 in a state where the table 54 is moved to the foremost (conveyor 20 side). It arrange | positions so that a big clearance gap may arise between the conveyor frames of 2nd conveyor 20B made. The other (lower side shown in FIG. 1) tray supply device 50 is the third conveyor in which the front end of the table 54 and the reference position are set in the state in which the table 54 is moved to the foremost (conveyor 20 side). It is arranged so as to be close to the 20C conveyor frame.

  Here, in the surface mounter 1, when the mounting operation is performed by the two head units 30 on the printed circuit boards P supported by the second conveyor 20B and the third conveyor 20C, depending on the mounting position, the two heads It is assumed that the units 30 interfere with each other. In this regard, since the tray supply device 50 is configured as described above, the conveyors 20B and 20C are moved to the rear end position BE by moving the table 54 of each tray supply device 50 to the limit offset shown in FIG. Can be placed in position. In the state where both conveyors 20B and 20C are at the limit offset position, as shown in FIG. 2, a predetermined width W1 is secured between the conveyors 20B and 20C in the direction orthogonal to the transport direction (Y-axis direction). Thus, such interference between the two head units 30 can be avoided.

(Operation mode of tray supply device)
Next, the operation | movement aspect of the tray supply apparatus 50 is demonstrated. In the tray supply device 50, when the electronic component E is mounted, the pallet 60 is put in and out and the table 54 is moved as follows.

  When the pallet 60 is pulled out from the pallet accommodating portion 52, first, the pallet 60 (the pallet 60 on which the electronic component E to be mounted is held) to be pulled out of the pallets 60 in the pallet rack 52B is lifted by the lifting mechanism. ) Is matched with the position of the pallet rail 70 in the vertical direction. Note that the operation of pulling out the pallet from the pallet accommodating portion 52 is performed in a state where the table 54 is moved to the rear end position BE. Next, the position of the pair of hooks 55 is controlled by the hook moving mechanism so as to coincide with the position of the locked portion of the pallet 60 to be pulled out.

  Next, the pair of air cylinders 72 is turned on, whereby the locked portion 66 of the pallet 60 to be pulled out is locked between the pair of hooks 55. Next, the pair of hooks 55 are moved along the hook rails 74 to the front end portion of the table 54 by the hook moving mechanism. As a result, the pallet 60 locked to the hook 55 is pulled out from the drawer opening 52A onto the table 54, and the front end of the pallet 60 is positioned at the front end of the table 54 (the solid line portion in FIG. 6).

  Next, the table 54 on which the pallet 60 is placed is moved according to the mounting mode of the electronic component E. Here, a case where the table 54 is moved forward is illustrated. When the pallet 60 is pulled out from the pallet accommodating portion 52 onto the table 54, the movable portion 84 is moved to the front end portion of the movable shaft 82 by the table moving mechanism, whereby the table 54 moves forward most along the table rail 80. It moves (see the dashed line portion in FIG. 5 and FIG. 7). Through the above operation, the pallet 60 holding the electronic component E to be mounted is supplied onto the base 10.

  When the pallet 60 on the table 54 is accommodated in the pallet accommodating part 52, such as when the remaining number of electronic components E in the pallet 60 is zero or when the electronic component E held on a different pallet 60 is mounted (pallet When the exchange of 60 is performed), the operation opposite to the above operation is executed. That is, first, the movable portion 84 is moved to the rear end portion of the movable shaft 82 by the table moving mechanism, whereby the table 54 moves most rearward along the table rail 80.

  Next, the pair of hooks 55 are moved along the hook rails 74 to the rear end of the table 54 by the hook moving mechanism. As a result, the pallet 60 locked to the hook 55 is pushed into the pallet accommodating portion 52 from the drawer opening 52A, and the front end of the pallet 60 is positioned in the drawer opening 52A. Next, the pair of air cylinders 72 are turned off, whereby the pair of hooks 55 are removed from the locked portions 66 of the pallet 60. The pallet 60 is again accommodated in the pallet accommodating part 52 by the above operation.

(Electrical configuration of surface mounter)
Next, the electrical configuration of the surface mounter 1 will be described with reference to FIG. The main body of the surface mounter 1 is entirely controlled by the control unit 90. The control unit 90 includes an arithmetic processing unit 91 configured by a CPU or the like. The arithmetic processing unit 91 is connected to a motor control unit 92, a storage unit 93, an image processing unit 94, an external input / output unit 95, a display device 96, and an input device.

  The motor control unit 92 drives the X-axis motor 30X, the Y-axis motor 30Y, the Z-axis motor 32Z, and the R-axis motor 32R of each head unit 30 according to a mounting program 93A described later. Further, the motor control unit 92 drives the elevating motor 52D, the hook moving motor 78, and the table moving motor 88 of each tray supply device 50 according to the mounting program 93A. Further, the motor control unit 92 drives the first conveyor motor and the second conveyor motor 22 of the conveyor according to the mounting program.

  The storage unit 93 includes a ROM (Read Only Memory) that stores a program for controlling the CPU, a RAM (Random Access Memory) that temporarily stores various data during operation of the apparatus, and the like. The storage unit 93 stores a mounting program 93A and various data 93B described below.

  Specifically, the mounting program 93A stored in the storage unit 93 includes board information regarding the number of printed circuit boards P to be mounted and the number and type of electronic parts E mounted on the printed circuit board P. Information, mounting information on the mounting position of the electronic component E on the printed circuit board P, and the like are included.

  The various data 93B stored in the storage unit 93 includes substrate data such as dimensions of the printed circuit board P to be mounted, the number and types of electronic components E held on each pallet 60 in the tray supply device 50, and the like. , Data on the position of the electronic component E in the tray 62 of each pallet 60 (an example of position information) (including data on the interval between the individual electronic components E accommodated in the tray 62), and the like. .

  The image processing unit 94 is configured to capture image signals output from the board recognition camera C1 and the component recognition camera C2. In the image processing unit 94, analysis of the component image and analysis of the board image are performed based on the captured image signals from the cameras C1 and C2, respectively.

  The external input / output unit 95 is a so-called interface, and is configured to receive detection signals output from various sensors 95 </ b> A provided in the main body of the surface mounter 1. The external input / output unit 95 is configured to perform operation control on various actuators 95B such as a pair of air cylinders 72 provided in the tray supply device 50 based on a control signal output from the arithmetic processing unit 91. Has been.

  The display device 96 is composed of a liquid crystal display device having a display screen, and displays the state of the surface mounter 1 on the display screen. The input device 97 is a device that includes a keyboard or the like and receives input from the outside.

  In the surface mounter 1 according to the present embodiment, during automatic operation, the conveyance state in which the printed circuit board P is conveyed by the conveyance conveyor 20 and the mounting state in which the electronic component E is mounted on the printed circuit board P are alternately displayed. To be executed. The transport state includes a state in which the second conveyor 20B and the third conveyor 20C on which the printed circuit board P is supported move from the reference position to the offset position.

  In the surface mounter 1 of the present embodiment, the control unit 90 executes a mounting position determination process for determining the mounting position of the printed circuit board P, that is, the positions of the second conveyor 20B and the third conveyor 20C, in the transport state. The mounting position determination process is executed based on the mounting program 93A and various data 93B stored in the storage unit 93. In the mounted state, the electronic component E is mounted at the mounting position determined by the mounting position determination process.

(Mounting position determination process)
The surface mounter 1 according to the present embodiment has the above-described configuration. Next, the mounting position determination process executed by the control unit 90 in the transport state will be described with reference to the flowchart shown in FIG. . In the surface mounter 1, the mounting position determination process is similarly performed for the printed circuit board P supported by the second conveyor 20B and the printed circuit board P supported by the third conveyor 20C.

  In the mounting position determination process, the control unit 90 first reads the mounting program 93A from the storage unit 93, and is mounted on the printed circuit board P on which the electronic component E is mounted based on the component information and the like of the read mounting program 93A. It is determined whether or not the electronic component E is the electronic component E supplied by the tray supply device 50 (S2). That is, the control unit 90 determines whether to use the tray supply device 50 in the mounting operation of the electronic component E.

  When determining that the tray supply device 50 is to be used (S2: YES), the control unit 90 proceeds to S4. On the other hand, when determining that the tray supply device 50 is not used (S2: NO), the control unit 90 determines whether or not the table 54 of the tray supply device 50 is at the rear end position BE (S12).

  When the controller 90 determines in S12 that the table 54 is at the rear end position BE (S12: YES), the controller 90 proceeds to S14. When determining that the table 54 is not at the rear end position BE (S12: NO), the control unit 90 controls the amount of movement of the table 54 so that the table 54 is at the rear end position BE (S16), and proceeds to S14. To do. That is, in S16, the control unit 90 drives the table moving motor 88 via the motor control unit 92, and moves the table 54 to the rear end position BE.

  In S14, the control unit 90 determines the conveyor position of the second conveyor 20B (third conveyor 20C) as the limit offset position (S14), and ends the mounting position determination process. When the tray supply device 50 is not used, it is assumed that the feeder-type supply device 40 is used in the mounted state. In S14, the controller 90 determines the conveyor position as the limit offset position by setting the limit offset position, thereby avoiding the interference between the tray supply device 50 and the conveyor frame, and the second conveyor 20B (third conveyor 20C). This is because the mounting time of the electronic component E supplied by the feeder type supply device 40 can be shortened.

  In S4, the control unit 90 reads various data 93B relating to the electronic component E to be mounted from the storage unit 93 (S4), and executes a calculation process to be described later based on the read various data 93B. When the calculation process ends, the control unit 90 controls the movement amount of the table 54 based on the calculation result of the calculation process (S8), and proceeds to S10. That is, in S8, the control unit 90 drives the table moving motor 88 via the motor control unit 92 based on the suction position calculated in the calculation process, and moves the table 54 of the tray supply device 50.

  In S10, the control unit 90 determines the position of the conveyor of the second conveyor 20B (third conveyor 20C) close to the table 54 (S10), and ends the mounting position determination process. In the surface mounter 1 of the present embodiment, when the mounting position determination process ends, the conveyors 20B and 20C move based on the conveyor position determined in the mounting position determination process, and shift to the mounting state.

(Calculation process)
Next, the calculation process executed by the control unit in S6 will be described with reference to the flowchart shown in FIG. In this calculation process, the control unit 90 attracts the electronic component E when the mounting time of the electronic component E is the shortest for the electronic component E to be mounted based on the information read from the storage unit 93. Calculate the position. In the surface mounter 1, the calculation process is similarly performed for the printed circuit board P supported by the second conveyor 20B and the printed circuit board P supported by the third conveyor 20C, similarly to the mounting position determination process. .

  In the calculation process, the control unit 90 first determines whether or not the suction position of the electronic component E can be overlapped with the component recognition camera C2 in the transport direction (S22). In other words, the control unit 90 determines whether or not a position that overlaps the recognition position in the transport direction is included in the range that is the suction position (the electronic component E can be sucked by the head unit 30).

  For example, when the electronic component E is not held on the front side of the tray 62 in the pallet 60 and the electronic component E to be mounted is held only on the rear side of the tray 62, the table 54 is moved to the front end position FE. Even if the electronic component E is moved, the position that overlaps the recognition position in the transport direction may not be included in the suckable range of the electronic component E. In this case, in S22, the control unit 90 determines that they cannot be overlapped.

  When the control unit 90 determines that the stacking cannot be performed in S22 (S22: NO), the suction position when the table 54 is moved to the front end position FE is calculated as the suction position when the mounting time is the shortest. (S34). For example, when the electronic component E is held only on the rear side of the tray 62 as described above, the suction position P1 is moved to the mounting position P3 by moving the table 54 to the front end position FE as shown in FIG. This is because the head unit 30 can be close to each other, and the mounting time from the suction position P1 through the recognition position P2 to the mounting position P3 can be shortened. Note that reference numeral A <b> 1 in FIG. 14 indicates a suckable range of the head unit 30. When the process of S34 ends, the control unit 90 ends the calculation process.

  If the control unit 90 determines that they can be matched in S22 (S22: YES), the control unit 90 determines whether or not the pallet 60 needs to be replaced during the mounting of the printed circuit board P on which the electronic component E is mounted (S24). . That is, the control unit 90 determines whether the electronic component E to be mounted is distributed and held on the plurality of pallets 60.

  If the controller 90 determines that no replacement is required in S24 (S24: NO), the controller 90 calculates the suction position of the electronic component E that overlaps the recognition position in the transport direction as the suction position when the mounting time is the shortest ( S32). For example, as shown in FIG. 15, by moving the table 54 to a position where the recognition position P2 and the suction position P1 overlap in the transport direction, the distance between the suction position P1 and the recognition position P2 becomes the shortest. This is because the mounting time from when the head unit 30 reaches the mounting position P3 through the recognition position P2 through the suction position P1 can be shortened.

  Further, as shown in FIG. 16, even when the remaining number of electronic components E in the front row of the tray 62 in the pallet 60 is zero, the suction located in the second row from the front of the tray 62 in the transport direction. The table 54 is moved so that the position P1 overlaps the recognition position P2, and the second row is set as the mounting target row, so that the distance between the suction position P1 and the recognition position P2 becomes the shortest. As a result, the head unit This is because the mounting time from the suction position P1 to the mounting position P3 through the recognition position P2 can be shortened. When the process of S32 ends, the control unit 90 ends the calculation process.

  When determining that the replacement is necessary in S24 (S24: YES), the controller 90 recognizes the suction position in the direction orthogonal to the transport direction and the mounting time when the recognition position and the suction position overlap in the transport direction. The mounting time when it is behind the position is compared (S26), and the process proceeds to S28. Here, the mounting time when the suction position is behind the recognition position refers to the mounting time in all cases where the suction position is behind the recognition position within the suction range.

  In S26, the mounting time when the control unit 90 is behind the mounting time when the control unit 90 overlaps is compared with the time required for replacing the pallet 60, that is, the table 54 is moved to the rear end position BE and then moved up and down. This is because the time required to put in and out the pallet 60 by the mechanism and the hook moving mechanism is much longer than the time required to move the table 54 to change the mounting target row of the tray 62 in the pallet 60. . Therefore, when the pallet 60 is exchanged, the mounting time may be shortened when the suction position is behind the recognition position than when the recognition position and the suction position are overlapped in the transport direction. .

  In S <b> 28, the control unit 90 determines whether or not the mounting time at the rear side can shorten the mounting time than the mounting time at the time of overlapping. When the control unit 90 determines in S28 that the mounting time when the overlapping overlaps the mounting time can be shortened compared to the mounting time when moving backward (S28: NO), the electronic component overlapping the recognition position in the transport direction The suction position E is calculated as the suction position when the mounting time is the shortest (S32). As described above, in this case, the distance between the suction position P1 and the recognition position P2 is the shortest. As a result, the mounting time required for the head unit 30 to reach the mounting position P3 from the suction position P1 through the recognition position P2. This is because it can be shortened (see FIG. 15). When the process of S32 ends, the control unit 90 ends the calculation process.

  When the control unit 90 determines in S28 that the mounting time at the rear can shorten the mounting time compared to the mounting time at the time of overlapping (S28: YES), the mounting in all the rear cases is performed. The suction position where the mounting time is the shortest in time is calculated (S30). For example, as shown in FIG. 17, even when the mounting target row is the front row of the tray 62 and the suction position P1 can be overlapped with the recognition position P2 in the transport direction, the pallet 60 is exchanged. When the mounting time at the rear can shorten the mounting time, the suction position P1 is calculated as the shortest mounting time among the mounting times at all the rear. When the process of S30 ends, the control unit 90 ends the calculation process.

(Effect of embodiment)
As described above, in the surface mounter 1 of this embodiment, when the tray supply device 50 is not used, that is, when only the feeder-type supply device 40 is used, the table 54 is moved to the front end position FE, and the conveyor position is limited. Since the offset position is set, the second conveyor 20B (third conveyor 20C) can be brought closest to the feeder-type supply device 40 while avoiding interference between the tray supply device 50 and the conveyor frame. The mounting time of the electronic component E supplied by 40 can be shortened.

  On the other hand, when the tray supply device 50 is used, the suction position when the mounting time is the shortest is calculated by the calculation process executed by the control unit 90. In this calculation process, when the suction position and the recognition position can be overlapped in the transport direction, when it is necessary to replace the pallet 60 during the mounting, the suction position and the recognition position are overlapped in the transport direction rather than the position where the suction position and the recognition position overlap. When the suction position is positioned behind the recognition position in the direction orthogonal to the transport direction, the suction position is calculated in various forms such as when the mounting time is shortened. Further, the second conveyor 20B (third conveyor 20C) may be closest to the tray supply device 50 while avoiding interference between the tray supply device 50 and the conveyor frame according to the suction position calculated in the calculation process. it can.

  As described above, in the surface mounter 1 of the present embodiment, when the tray supply device 50 is used, various mounting modes of the electronic component E to be mounted while avoiding interference between the tray supply device 50 and the conveyor frame. Accordingly, the mounting time of the electronic component E can be shortened.
