  The suction nozzle 15 can be moved up and down by a vertical axis motor 20, and by rotating the mounting head 16 around the vertical axis by a θ-axis motor 21, as a result, each suction nozzle 15 of each mounting head 16 is moved in the X direction. And can be moved in the Y direction, can rotate around a vertical line, and can move up and down.

  Reference numeral 18 denotes a component recognition camera that images the electronic component sucked and held by the suction nozzle 15, and reference numeral 22 denotes a board recognition camera that picks up a board recognition mark attached to the printed circuit board 6 and is mounted on each mounting head 16. Yes.

  23 is a nozzle stocker for storing various suction nozzles 15, two can be installed at the back side position of the transport device 12 and two at the near side position, and because the shape and size of the suction nozzle 15 are different, Different types are prepared.

  Next, a control block diagram according to the electronic component mounting apparatus 1 of FIG. 3 will be described. First, reference numeral 30 is a control means for comprehensively controlling the operation related to the mounting of the mounting apparatus, determination means for making various determinations, comparison means for making various comparisons, a CPU as an execution means, and 31 in the order of electronic component mounting step numbers. Mounting data (see FIG. 5) including mounting coordinate information including the X direction, Y direction, and angular position in the printed circuit board 6 and the arrangement number information of each component supply unit 13B (see FIG. 5), and the component supply unit 13B. RAM (Random Access Memory) as storage means for storing component placement data (see FIG. 6) related to the component ID for each placement number, component library data composed of electronic component size data for each electronic component, etc. Reference numeral 32 denotes a ROM (Read Only Memory) for storing a program.

  The mounting data, component arrangement data, component library data, and the like stored in the RAM 31 are also stored in the data server 7. In the data server 7, the serial number of the component supply unit 13B and the component ID are associated with each other and stored as feeder / component related information.

  The CPU 30 controls the operation related to the component mounting operation of the electronic component mounting apparatus according to the program stored in the ROM 32 based on the data stored in the RAM 31. That is, the CPU 30 controls driving of the X-direction linear motor 19, the Y-direction linear motor 17, the vertical axis motor 20, and the θ-axis motor 21 via the interface 33 and the drive circuit 36.

  A recognition processing device 26 is connected to the CPU 30 via an interface 33. The recognition processing device 26 performs recognition processing of images captured by the component recognition camera 18 and the board recognition camera 22. The processing result is sent to the CPU 30. In other words, the CPU 30 outputs an instruction to the recognition processing device 26 so as to perform recognition processing (such as calculation of a displacement amount) on the images picked up by the component recognition camera 18 and the board recognition camera 22, and recognizes the recognition processing result. It is received from the processing device 26.

  That is, when the amount of displacement of the electronic component is grasped by the recognition processing of the recognition processing device 26, the result is sent to the CPU 30, and the CPU 30 adds the amount of displacement of the electronic component to the amount of displacement of the printed circuit board 6. The beams 4A and 4B are moved in the Y direction by driving the Y-direction linear motor 17, and the mounting head 16 is rotated in the X direction by driving the X-direction linear motor 19, and the θ-axis motor 21 is rotated by θ. , X, Y directions and rotation angle positions around the vertical axis are corrected.

  The CPU 30 also has a monitor 27 for displaying an operation screen, a touch panel switch 28 as an input device formed on the display screen of the monitor 27, and component information (components) attached to a supply reel on which a storage tape is wound and stored. A barcode reader 29 for reading a barcode representing (ID) and a barcode representing a serial number assigned to the component supply unit 13B is connected via an interface 33.

  The component supply unit 13B disposed on the feeder base 13A is provided with the other connector 33B connected to one connector 33A provided on the front surface of the feeder base 13A. The component supply unit 13B includes a control device 34 composed of a microcomputer and a memory 35 in which a serial number is stored.

  Next, description will be made based on FIG. 4 of the flowchart relating to the control of the electronic component mounting apparatus 1 of the present invention. Initially, the electronic component was mounted on the printed circuit board 6 of the model “1” until now, but it is used for the production of the printed circuit board 6 of the model “1” when the mounting operation is currently stopped. When an abnormality or an out of electronic component occurs in the component supply unit 13B to be operated, the work manager uses the feeder A (a component supply unit 13B) used in the model “1” of the printed circuit board 6 as the feeder base 13A. Then, the abnormal state is repaired, or the supply tape storing the storage tape storing the new electronic components is replaced with the supply reel, and mounted on the feeder base 13A (step S01).

  In this case, since the CPU 30 is connected to a power source (not shown), the power can be supplied to the component supply unit 13B by attaching the component supply unit 13B to the feeder base 13A and connecting the connectors 33A and 33B. Conversely, when the connection between the connectors 33A and 33B is released, the power supply to the component supply unit 13B is cut off to zero volts, and the CPU 30 can detect this cut-off state. Therefore, as a result, it is possible to detect the connection state (power supply state) and the non-connection state (power supply cutoff state) of the component supply unit 13B to the feeder base 13A.

  For this reason, the CPU 30 knows which component supply unit 13B associated with the arrangement number used for mounting the electronic component of the printed circuit board 6 of the model “1” has been detached, so that the component supply unit 13B which has been detached and attached to the RAM 32 and the data server 7. The arrangement number is stored for each detachment.

  At this time, for example, when the component supply unit 13B having the arrangement numbers “217” and “218” for handling the electronic components to be mounted on the model “1” of the printed circuit board 6 is removed from the feeder base 13A, the arrangement number Since the component supply unit 13B has been removed and the component ID is known from the mounting data of FIG. 5 and the component arrangement data shown in FIG. 6 stored in the RAM 31, the arrangement number “Fdr No. ( The CPU 30 displays the component supply unit arrangement number ”(“ 217 ”and“ 218 ”), the“ component ID ”(“ C1005T05B0 ”and“ R1005T04B0 ”), the remaining component count and the ACV check (“ not checked ”) on the monitor 27. In this case, even if the component supply unit 13B having the arrangement number “215” used for the next production model “2” is detached. The arrangement number "215" is not displayed, wherein are displayed only the component supply unit 13B to be used for production type "1".

  In addition to the component supply unit 13B used for the production of the printed circuit board 6 of the model “1” as described above, the model “2” of the next model or the printed circuit board 6 of the model after the next model “2” or the like. In the same way as described above, even when an abnormality or an out of electronic component occurs in the component supply unit 13B used for production, the work manager uses the feeder B (a certain component supply unit 13B) used for the model “2” or the like as described above. It is removed from the feeder base 13A and mounted (step S02).

  Therefore, since the CPU 30 knows which arrangement number of the component supply unit 13B is attached / detached, the arrangement number of the attached / removed component supply unit 13B is stored in the RAM 32 and the data server 7 each time this attachment / detachment is performed.

  Next, the touch panel switch displayed on the monitor 27 is used to confirm whether the component supply unit 13B used for the production of the printed board 6 of the model “1” attached to and detached from the feeder base 13A by the work manager. When the feeder ready switch is pressed (step S03), the CPU 30 performs a cross check of the component supply unit 13B with the model “1” attached / detached (step S04).

  That is, in this case, when the feeder ready switch is pressed, the CPU 30 triggers the serial number of the detached component supply unit 13B used for the model “1” of the printed circuit board 6, that is, the component supply unit 13B. From the data server 7 storing the feeder / component related information in which the serial number of the component supply unit 13B and the component ID are associated with each other based on the serial number obtained from the memory 35 provided in Get the part ID. The component ID of the component supply unit 13B obtained from the data server 7 and the component ID of the component arrangement data in FIG. 6 corresponding to the arrangement number of the mounting data shown in FIG. 5 (in the RAM 32 and the data server 7 at the time of attachment / detachment). Compared with the corresponding component ID obtained from the component arrangement data using the stored arrangement number as a clue, the cross check of the detached component supply unit 13B of the model “1” is executed.

  The result of the cross check is displayed on the screen of the monitor 27 as shown in FIG. That is, the arrangement number “Fdr No.” (“217” and “218”), “component ID” (“C1005T05B0” and “R1005T04B0”), the number of remaining components, and the ACV check (“not consistent”) are displayed on the monitor 27. Is displayed. In this case, even if the component supply unit 13B with the arrangement number “215” used for the next production model “2” is detached, this arrangement number “215” is not displayed, and here it is used for the production model “1”. Only the result of executing the cross check of the component supply unit 13B is displayed.

  In the case of “not consistent”, even if the work manager tries to start the production operation by pressing the operation start switch (not shown), the apparatus is abnormal and is controlled by the CPU 30 so that the production operation does not start. The In the case of “not consistent”, it means that the cross check matches but the consistency needs to be confirmed.

  Next, the CPU 30 determines whether or not the cross check is good (OK) based on the execution result of the cross check described above (step S05). If it is not good and it is determined that the crossing is wrong, the CPU 30 performs an abnormality process and displays it on the monitor 27, or notifies the abnormality by other notifying means and performs the electronic component registration process again (step S06). The process returns to step S03.

  If it is determined that the cross check is good, whether or not the component supply unit 13B to be used next has been detached, in other words, whether or not the component supply unit 13B related to the electronic component to be mounted on the printed board 6 of the model “1” has been detached. Is determined (step S07). In this case, since it can be known which component supply unit 13B related to which arrangement number has been attached, that is, since the arrangement number is stored in the RAM 32 and the data server 7, it can be determined.

  When the CPU 30 determines that the component supply unit 13B related to the electronic component mounted on the printed circuit board 6 of the model “1” is not attached / detached, the operation manager presses the operation start switch, thereby the model “1”. Is started (step S10).

  If it is determined that the component supply unit 13B related to the electronic component mounted on the printed circuit board 6 of the model “1” has been detached, the CPU 30 executes the consistency check of the electronic component of the model “1” (step S08). This consistency check is performed by comparing the component ID of the electronic component associated with the component supply unit 13B registered in the data server 7 and the component ID of the supply reel actually attached to the component supply unit 13B. Done.

  That is, the work manager uses the barcode reader 29 to read the barcode representing the component information (component ID) attached to the supply reel on which the storage tape is wound and stored, and to read the serial number attached to the component supply unit 13B. Read the bar code representing the number. Then, the CPU 30 obtains the component ID related to the read supply reel and the component ID corresponding to the serial number obtained by using the serial number read based on the feeder / component related information registered in the data server 7 as a clue. In comparison, the consistency check of the electronic component of the model “1” is executed.

  Then, it is determined whether or not the consistency check result is good (step S09). If it is determined that the consistency is not good, the CPU 30 performs an abnormality process and displays the abnormality on the monitor 27 or other abnormality by an informing means. The electronic component registration process is performed again (step S06), and the process returns to step S03. Then, the process returns from step S06 to step S03. Returning to step S03, if it is determined again whether the cross check is good, a screen as shown in FIG. That is, the arrangement number “Fdr No.” (“217” and “218”), “part ID” (“C1005T05B0” and “R1005T04B0”), the remaining part number and the ACV check (“OK (good)”) are displayed. It is displayed on the monitor 27. In this case, even if the component supply unit 13B with the arrangement number “215” used for the next production model “2” is detached, this arrangement number “215” is not displayed, and here it is used for the production model “1”. Only the result of executing the cross check of the component supply unit 13B is displayed.

  After confirming the consistency (step S08), it is determined that the above-described consistency confirmation result is good, and the detached arrangement used for mounting the electronic component on the printed circuit board 6 of the model “1” is used. If it is determined that the component supply unit 13B with the number “217” is good, the serial number (feeder SN) “GD08080-000002”, the registered component ID “C1005T05B0”, the component ID of the component supply unit 13B, as shown in FIG. When “C1005T05B0”, lane No. (arrangement number) “F217”, and determination result “OK (good)” are displayed on the monitor 27, and the component supply unit 13B with the arrangement number “218” is determined to be good. , As shown in FIG. 10, the serial number (feeder SN) “GD08080-000003” of the component supply unit 13B. , Registered part ID “R1005T04B0”, part ID “R1005T04B0”, lane number (arrangement number) “F218”, and determination result “OK (good)” are displayed.

  If it is determined that the result is good in step S09, the cross check result is displayed on the monitor 27 as shown in FIG. That is, the arrangement number “Fdr No.” (“217” and “218”), “part ID” (“C1005T05B0” and “R1005T04B0”), the remaining part number and the ACV check (“OK (good)”) are displayed. The operation of the model “1” is started by the operation manager pressing the operation switch (not shown) displayed on the monitor 27 (step S10).

  Here, the electronic component mounting operation of the electronic component mounting apparatus 1 will be briefly described. The printed circuit board 6 is received from the upstream work device (not shown), and the printed circuit board 6 is positioned and fixed by the substrate positioning unit. One beam 4A is moved in the Y direction by driving the Y direction linear motor 17, and the mounting head 16 provided on the beam 14A is moved in the X direction by the X direction linear motor 19, and the corresponding component supply unit according to the mounting data. 13B is moved to above the component take-out position, and the suction nozzle 15 provided in the mounting head 16 is lowered by driving the vertical axis motor 20 to take out the electronic component from the component supply unit 13B.

  After removal, the suction nozzle 15 of the mounting head 16 is raised and passed over the component recognition camera 18, and a plurality of electronic components sucked and held by the plurality of suction nozzles 15 during this movement are collectively imaged. Then, the recognition processing device 26 recognizes the captured image and grasps the positional deviation with respect to the suction nozzle 15.

  A board recognition camera 22 provided on each mounting head 16 moves to a position above the printed board 6 to pick up a board recognition mark attached to the printed board 6 and recognizes the taken image as a recognition processing device. 26 recognizes the position of the printed circuit board.

  Then, the electronic component is mounted on the printed circuit board 6 while the suction nozzle 15 corrects the positional deviation by adding the recognition processing result of the board recognition mark and each component recognition processing result to the mounting coordinates of the mounting data. When all the electronic components are mounted on the printed board 6 in this way, the board 6 is transferred from the board positioning unit to the post-process device via the board discharging unit, and the electronic components are placed on the printed board 6. The mounting operation ends.

  When the electronic component mounting production operation for all the printed circuit boards 6 related to the model “1” to be produced as described above is completed (step S11), the mounting operation is stopped, and the next printed circuit board to be produced is the next. The model is switched to a certain model “2” (step S12).

  That is, for the model “2” which is a printed circuit board of the next model, for example, replacement of the suction nozzle as work equipment, change of the conveyor width, rearrangement of backup pins, etc. are performed automatically or manually.

  Next, when the model is switched to the model “2”, which is the next printed circuit board 6 as described above, the CPU 30 makes a mistake in connecting the detached component supply unit 13B used for the model “2” of the printed circuit board 6. A check is executed (step S13).

  That is, in this case, the CPU 30 is based on the serial number of the detached component supply unit 13B used for the model “2” of the printed circuit board 6, that is, the serial number obtained from the memory 35 provided in the component supply unit 13B ( As a clue, the component ID is obtained from the data server 7 storing the feeder / component related information in which the serial number of the component supply unit 13B and the component ID are associated with each other. The component ID of the component supply unit 13B obtained from the data server 7 and the component ID of the component arrangement data in FIG. 6 corresponding to the arrangement number of the mounting data shown in FIG. 5 (in the RAM 32 and the data server 7 at the time of attachment / detachment). Compared with the corresponding component ID obtained from the component arrangement data using the stored arrangement number as a clue, the cross check of the detached component supply unit 13B of the model “2” is executed.

  The result of the cross check is displayed on the screen of the monitor 27 as shown in FIG. That is, the arrangement number “Fdr No.” (“215”, “217”, “218”), “part ID” (“C1005T05B1”, “C1005T05B0”, “R1005T04B0”), the remaining part number and the ACV check are displayed on the monitor 27. Is displayed. When this ACV check is “not consistent”, the CPU 30 controls the apparatus so that even if an attempt is made to start a production operation, the apparatus becomes abnormal and the production operation does not start.

  If the ACV check is “not consistent” and the work manager presses the operation start switch to start the production operation of the printed circuit board 6 related to the model “2”, the CPC 30 displays the monitor 32 on the monitor 32. 13 is displayed, and the component supply unit 13B with the removed arrangement number “215” used for mounting on the printed circuit board 6 relating to the model “2” is displayed with “F215, there is a component misplacement” "It has occurred."

  Next, the CPU 30 determines whether or not the cross check is good (OK) based on the execution result of the cross check described above (step S14). If it is not good and it is determined that the crossing is wrong, the CPU 30 performs an abnormality process and displays it on the monitor 27, or notifies the abnormality by other notifying means and performs the electronic component registration process again (step S15). When the work manager presses the feeder ready switch (step S16), the process returns to step S13, and the CPU 30 executes the cross check of the component supply unit 13B with the model “2” attached / detached again.

  If it is determined that the cross check is good, then the component supply unit 13B used for the model “2” has been detached, in other words, the component supply unit related to the electronic component mounted on the printed circuit board 6 of the model “2”. It is determined whether or not 13B has been detached (step S17). In this case, it is possible to determine which component supply unit 13B related to which arrangement number has been removed, that is, since the arrangement number of the detached component supply unit 13B is stored in the RAM 32 and the data server 7.

  When the CPU 30 determines that the component supply unit 13B related to the electronic component to be mounted on the printed board 6 of the model “2” is not attached / detached, the operation manager presses the operation start switch, thereby the model “2”. Is started (step S18).

  If it is determined that the component supply unit 13B related to the electronic component mounted on the printed circuit board 6 of the model “2” has been detached, the CPU 30 executes the consistency check of the electronic component of the model “2” (step S19). This consistency check is performed by comparing the component ID of the electronic component associated with the component supply unit 13B registered in the data server 7 and the component ID of the supply reel actually attached to the component supply unit 13B. Done.

  That is, the work manager uses the barcode reader 29 to read the barcode representing the component information (component ID) attached to the supply reel on which the storage tape is wound and stored, and to read the serial number attached to the component supply unit 13B. Read the bar code representing the number. Then, the CPU 30 obtains the component ID related to the read supply reel and the component ID corresponding to the serial number obtained by using the serial number read based on the feeder / component related information registered in the data server 7 as a clue. And confirming the consistency of the electronic component of model “2”.

  Then, it is determined whether or not the consistency check result is good (step S20). If it is determined that the consistency is not good, the CPU 30 performs an abnormality process and displays it on the monitor 27, or other abnormality is notified by the notification means. The electronic component registration process is performed again (step S15). When the work manager depresses the feeder ready switch (step S16), the process returns to step S13, and the CPU 30 supplies the component "2" with the model "2" removed. The cross check of the unit 13B is executed again.

  It is determined whether or not the consistency check result is good (step S20). If it is determined that the consistency check result is good, the cross check result is obtained as shown in FIG. 15, with the arrangement number “Fdr No.” (“215 ”,“ 217 ”,“ 218 ”),“ Part ID ”, remaining part number and ACV check (“ OK (good meaning) ”) are displayed on the monitor 27. Then, when the operation manager presses the operation start switch, the production operation of the printed circuit board 6 of the model “2” is started (step S18). In this case, the consistency check is executed (step S19), the result of the consistency check is determined to be good, and the detached arrangement used for mounting the electronic component on the printed board 6 of the model “2” is used. When it is determined that the component supply unit 13B with the number “215” is good, as shown in FIG. 14, the serial number (feeder SN) “GD08080-000001”, the registered component ID “C1005T05B1”, the component ID of the component supply unit 13B “C1005T05B1”, lane No. (arrangement number) “F215”, and determination result “OK (good)” are displayed on the monitor 27.

  After confirming the consistency of the component supply unit 13B with the arrangement number “215” (steps S19 and S20), the process returns to step S13, and the CPU 30 makes a mistake in the component supply unit 13B with the model “2” attached and detached. When it is determined that the check is good (step S14), as shown in FIG. 15, the arrangement number “Fdr No.” (“215”, “217”, “218”), “part ID” ", The number of remaining parts and the ACV check (" OK (good) ") are displayed on the monitor 27. That is, in addition to the ACV check result of the component supply unit 13B with the arrangement numbers “217” and “218” used for mounting the electronic component on the printed board 6 of the model “1”, the print of the model “2” The ACV check result of the component supply unit 13B having the removed arrangement number “215” used for mounting the electronic component on the board 6 is additionally displayed.

  Note that, after the production of the model “2” of the printed circuit board P is finished, the same control as described above (steps S16 to S20) is performed even after the model is changed to the next model.
