The second component supply device 3D includes a lid body 20 that has a door body 19 that covers an opening having one side and that can open and close an opening for taking out the magazine 15 for replacement at upper, middle, and lower positions. A supply device main body 21, two magazines 15 for storing a plurality of pallets 14 on which trays 13 in which a large number of electronic components are arranged and arranged in the supply device main body 21 are stored, and a predetermined one of the magazines 15 An elevator mechanism 17 that vertically conveys the pallet 14 to a drawer level position (a position of the chute 16 provided in the electronic component mounting apparatus 1), which is a predetermined movement level position, and a magazine 15 replacement position, and the pallet 14 to the elevator mechanism 17 and a pallet introducing mechanism 18 that conveys in a horizontal direction from the pickup area of the apparatus main body 2 to the pickup area. The pallet introduction mechanism 18 may be provided in the first component supply device, and the second component supply device may be attached to the apparatus main body 2 via the first component supply device.

  As shown in FIGS. 4 and 5, the elevator mechanism 17 includes two guide rails 22 and a slider 23 that can move up and down along the guide rails 22, and places the magazine 15 thereon.

  The upper door body 19 is provided with an operation switch 35 for raising the upper magazine 15, and the middle door body 19 is provided with operation switches 36 and 37 for raising and lowering the upper or lower magazine 15, and the lower door body. 19, an operation switch 38 for lowering the lower magazine 15 is provided. Each door body 19 is similarly provided with a handle 19A and a transparent or translucent window 19B.

  When the electronic component mounting apparatus is stopped when the magazine 15 is replaced for the replacement of the printed circuit board P, or when a large number of pallets 14 for mounting the tray 13 for storing predetermined components are replaced. When any one of the operation switches 35, 36, 37, 38 is operated, the CPU 41, which is a control device that comprehensively controls the electronic component mounting device, drives the lifting drive motor 27 for the vertical movement of the corresponding magazine 15. Then, it is moved to a position corresponding to the door body 19, and with this movement stop, a drive source of a lock mechanism (not shown) of the door body 19 is driven to release the lock.

  That is, when the operation switch 35 is operated, the upper lifting / lowering drive motor 27 is driven to move the upper magazine 15 to a position corresponding to the upper door body 19, and when the operation switch 36 is operated, the upper lifting / lowering drive motor 27 is moved. The upper magazine 15 is moved to a position corresponding to the middle door body 19 by driving, and when the operation switch 37 is operated, the lower magazine 15 corresponds to the middle door body 19 by driving the lower lifting drive motor 27. When the operation switch 38 is operated, the CPU 41 controls the lower magazine 15 to be moved to a position corresponding to the lower door body 19 by driving the lower raising / lowering drive motor 27. .

  FIG. 8 is a control block diagram for control related to electronic component mounting of the electronic component mounting apparatus 1 and will be described below. Each element of the electronic component mounting apparatus 1 is centrally controlled by a CPU (central processing unit, which serves as both a control unit and a calculation unit) 41, and a ROM (read An only memory (RAM) 42 and a RAM (random access memory) 43 which is a storage means for storing various data are connected via a bus line 44. Further, a monitor 45 for displaying an operation screen and the like and a touch panel switch 46 as an input means formed on the display screen of the monitor 45 are connected to the CPU 41 via an interface 47. Further, the Y-direction linear motor 51 and the like are connected to the CPU 41 via a drive circuit 48 and an interface 47. The signal line and the power line of the lifting motor 27 are connected to the drive circuit 48 by a connector (not shown).

  In the RAM 43, for each mounting order, mounting data including X direction, Y direction and angle information of mounting coordinates of each electronic component in the printed circuit board P, arrangement number information of each component supply unit 5, and the like. Is stored. The RAM 43 stores information on the type of each electronic component corresponding to the arrangement number of each component supply unit 5, and a component library relating to the characteristics such as the size and feed pitch of the electronic component for each electronic component. Data etc. are stored.

  A recognition processing device 49 is connected to the CPU 41 via the interface 47, and the recognition processing device recognizes an image captured by the component recognition camera 12 by picking up an electronic component sucked and held by the suction nozzle 7. At 49, the processing result is sent to the CPU 41. That is, the CPU 41 outputs an instruction to the recognition processing device 49 so as to perform recognition processing (calculation of the amount of positional deviation with respect to the suction nozzle 7) on the image captured by the component recognition camera 12, and also recognizes the recognition processing result. Is received from.

  A pallet drawer side end on the upper magazine base 24 is provided with a dog 56 having a vertical length of 7 mm, and on the main body side of the second component supply device 3D that does not interfere with the pallet 14 withdrawal. A transit sensor 57 composed of an optical sensor is provided on a chute 16 to detect the dog 56. That is, the light emitted from the light emitting element of the transit sensor 57 is shielded by the dog 56 and the presence of the dog 56 is detected.

  As described above, the level position of the desired pallet 14 of the upper and lower magazines 15 is matched with the level position of the chute 16 by the lifting operation by the elevator mechanism 17, and the desired pallet 14 is moved by the pallet introduction mechanism 18. The tray 13 on the pallet 14 is pulled out and introduced into the pickup area along the chute 16 so that the suction nozzle 7 can take out the suction. Therefore, if the level position of the desired pallet 14 of the magazine 15 does not match the level position of the chute 16, the pallet introduction mechanism 18 reliably pulls out the desired pallet 14 from the magazine 15. I can't.

  For this reason, when the first component supply device is removed from the electronic component mounting device 1 and the second component supply device 3D is newly attached to the electronic component mounting device 1, for example, the teaching relating to the pallet drawer offset is automatically performed. The following description will be made according to the flowchart shown in FIG.

  First, the work manager does not enter the electronic component mounting apparatus 1 and presses the touch panel switch 46 formed on the display screen of the monitor 45 to display the menu screen and display this teaching screen. To start. In this case, the upper magazine 15 will be described as an example. First, in the state where the upper magazine 15 (elevator mechanism 17) is at the origin position, the corresponding elevator mechanism 17 is driven to place the upper magazine 15 in the design position. Move down to. That is, the CPU 41 drives and controls the upper lift drive motor 27 to drive the elevator mechanism 17, and the predetermined position of the upper magazine 15 as shown in FIG. 6, for example, the level position of the lower pallet 14 and the chute 16. Control is performed so that the upper magazine 15 moves downward to a design position where the level position coincides, that is, the distance between the optical axis LB of the light emitting element of the transit sensor 57 and the upper end of the dog 56 is 12 mm. Note that the magazine 15 was at the original position before starting teaching, but it may be moved to the original position first after starting teaching.

  In this case, the level shift between the electronic component mounting device 1 and the component supply device 3D when the second component supply device 3D is brought close to or away from the distance of 12 mm is actually controlled by the above-described downward movement control of the magazine 15. The magazine 15 stops at a distance obtained by adding α, that is, 12 + α.

  Next, after the upper magazine 15 is moved down to the design position and the lifting drive motor 27 is stopped, the CPU 41 drives and controls the upper lifting drive motor 27 to drive the elevator mechanism 17, and the upper magazine 15. Move up. Then, along with this movement, the connecting sensor 57 detects the upper end of the dog 56 (the optical axis LB of the connecting sensor 57 and the upper end of the dog 56 are at the same height level) and is turned on. The drive motor 27 (elevator mechanism 17) is controlled to stop.

  Next, the CPU 41 drives and controls the elevating drive motor 27 to raise the magazine 15 via the elevator mechanism 17 so as to raise the connecting sensor 57 by 3.5 mm from the position where the dog 56 is detected. After the 3.5 mm rise, the CPU 41 controls the elevator drive motor 27 (elevator mechanism 17) to stop. Since the length of the dog 56 in the vertical direction is 7 mm, the elevator mechanism 17, that is, the magazine 15 is stopped at the intermediate position of the dog 56 (the position at which the transfer sensor 57 detects the magazine). Will be.

  Next, the CPU 41 drives and controls the upper lift drive motor 27 to drive the elevator mechanism 17 so that the magazine 15 is lowered, and to control the dog 56 to be lowered from the position where it is raised by 3.5 mm. .

  Then, the connection sensor 57 moves to a position where the upper end of the dog 56 is not detected (position where the connection sensor 57 does not detect the magazine 15). That is, when the magazine 15 moves down by 3.5 mm, the connection sensor 57 is turned off. Therefore, the CPU 41 controls the elevator drive motor 27 (elevator mechanism 17) to stop. Further, the current position of the magazine 15 at this time, more precisely, the height level position of the lowermost pallet 14 of the magazine 15 (in other words, the actual length from the origin position of the upper magazine 15) is stored in the RAM 43. To control.

  Then, the counter 58 counts the number of teachings, and the CPU 41 performs control so that the above teaching is repeated, for example, five times. When the five teachings are completed, the CPU 41 calculates a pallet drawer offset value. That is, the average value of the five teaching results is obtained, and 12 mm (the difference between the position of the optical axis LB of the connecting sensor 57 at the pull-out position of the lowermost pallet 13 and the upper end position of the dog 56) is subtracted from this average value. Further, the CPU 41 calculates the pallet drawer offset value by drawing the design position related to the drawer position of the lowermost pallet 14 of the magazine 15. In the present embodiment, the current position of the magazine 15 is calculated five times. However, the present invention is not limited to this, and it may be one or more times.

  The pallet drawer offset value, which is the calculation result, is stored in the RAM 43 and is reflected as will be described later during the actual pallet drawer operation. The desired pallet 14 of the upper and lower magazines 15 is moved by the elevator mechanism 17. Can be matched with the level position of the chute 16. For this reason, the desired pallet 14 is pulled out by the pallet introducing mechanism 18, and the tray 13 on the pulled pallet 14 is introduced into the pickup area along the chute 16, so that the suction nozzle 7 can take out the suction. it can.

  With the above configuration, the operation of the electronic component mounting apparatus will be described. First, two printed circuit boards P from an upstream device (not shown) are supplied to the supply conveyor, two printed circuit boards P from the supply conveyor to the positioning unit 8 (having a conveyor), and two printed circuit boards P from the discharge conveyor. To the downstream device.

  At this time, when the two printed boards P are conveyed to the positioning unit 8, the printed boards P are positioned and fixed by the positioning mechanism. Then, each electronic component taken out by the suction nozzle 7 from the first component supply device 3A and the second component supply device 3D on the left printed circuit board P and the first component supply device 3B on the right printed circuit board P are also obtained. And each electronic component taken out from the 1st component supply apparatus 3C will be mounted | worn according to the mounting data stored in RAM43.

  That is, the Y direction linear motor 51 is driven in the Y direction to move each beam 10, and the X direction linear motor 52 is driven in the X direction to move the mounting head 6 along each beam 10 without colliding. Then, it moves so as to be positioned above the component supply device 3 for storing the electronic components to be sequentially mounted, and the suction nozzle 7 of each mounting head 6 is lowered by the vertical axis motor 53 to pick up and take out the electronic components. Then, the electronic component is moved upward above the corresponding component recognition camera 12 and picked up and picked up by the suction nozzle 7, and the recognition processing device 49 recognizes the position of the electronic component.

  Then, the CPU 41 calculates the amount of displacement based on the recognition result by the recognition processing device 49, adds the calculation result to the mounting data, moves the printed circuit board P and moves it around the vertical axis by the θ-axis motor 54. By rotating, an electronic component is mounted at a predetermined position (angle) on a predetermined position of the printed circuit board P.

  In this case, in the left part of the electronic component mounting apparatus 1, the front and rear beams 10 and the suction nozzle 7 of the mounting head 6 moving along each beam 10 mount the electronic component on the left printed board P. In the right part, the front and rear beams 10 and the suction nozzle 7 of the mounting head 6 moving along each beam 10 mount the electronic component on the right printed board P.

  At this time, when the electronic component to be mounted is stored in the second component supply device 3D, the drawing operation of the pallet 14 starts to mount the electronic component. That is, when the elevator drive motor 27 is controlled by the CPU 41 and the elevator mechanism 17 is driven to move the magazine 15, the magazine 43 is stored in the RAM 43 and the pallet drawer offset value is taken into account to store the electronic components to be mounted. The magazine 15 moves so that the level position of the 15 pallets 14 matches the level position of the chute 16 of the pallet introducing mechanism 18. Accordingly, the locking arm 31 can be advanced by the drive mechanism 32 and the hook can be securely locked to the tip of the pallet 14 accommodated in the magazine 15, and then the locking arm 31 can be moved backward to move the pallet. 14 is introduced along the chute 16 into the pickup region, and the suction nozzle 7 can suck and take out the electronic components.

  At this time, the suction nozzle 7 is lifted by the vertical axis motor 53 after picking up the components, and the suction operation is completed when it moves a predetermined distance, but the pallet introduction mechanism 18 returns the pallet 14 to the magazine 15.

  Depending on the type of electronic component to be mounted, the corresponding upper or lower magazine 15 for storing the pallet 14 mounted with the electronic component via the tray 13 is moved up and down by the elevator mechanism 17 at a predetermined level position. The pallet 14 is pulled out.

  Here, the first component supply device is removed from the electronic component mounting apparatus 1 in order to change the setup of the printed circuit board P to be processed, and this second component supply device is newly added to the electronic component mounting apparatus 1 instead. Although 3D is attached, teaching related to the pallet drawer offset as described above is performed at this time, and the description is omitted here.

  Note that a detection device that detects that the second component supply device 3D is attached to the electronic component mounting device 1 may be provided to automatically teach the pallet drawer offset as described above.

  Although the embodiments of the present invention have been described above, various alternatives, modifications, and variations can be made by those skilled in the art based on the above description, and the present invention is not limited to the various alternatives described above without departing from the spirit of the present invention. It includes modifications or variations.
