  Hereinafter, an electronic component mounting apparatus including a component supply apparatus and an electronic component mounting apparatus main body will be described with reference to the accompanying drawings. This electronic component mounting apparatus is a so-called multifunctional chip mounter, and various electronic components can be mounted on the printed circuit board P.

  FIG. 1 is a plan view of an electronic component mounting apparatus. An electronic component mounting apparatus main body 1 includes a machine base 2, a conveyor unit 3 extending in the left-right direction at the center of the machine base 2, and a front of the machine base 2. Two sets of component mounting portions 4 and 4 and two sets of component supply portions 5 and 5 are provided respectively at a portion (lower side in the drawing) and a rear portion (upper side in the drawing). Then, a plurality of component supply units 6 that are electronic component supply devices are detachably incorporated in the component supply unit 5 to constitute an electronic component mounting device.

  The conveyor unit 3 includes a central set table 8, a left supply conveyor 9, and a right discharge conveyor 10. The printed circuit board P is supplied from the supply conveyor 9 to the set table 8, and is fixedly set at a predetermined height so as to receive mounting of electronic components on the set table 8. Then, the printed circuit board P on which the mounting of the electronic components is completed is discharged from the set table 8 to the downstream device via the discharge conveyor 10.

  Each component mounting portion 4 is provided with an XY stage 12 on which a head unit 13 is movably mounted, as well as a component recognition camera 14 and a nozzle stocker 15. The head unit 13 is equipped with two mounting heads 16 and 16 for sucking and mounting electronic components, and one substrate recognition camera 17 for recognizing the position of the printed circuit board P.

  In each XY stage 12, the beam 12A is moved in the Y direction by the Y axis drive motor 12Y, and the head unit 13 is moved in the X direction by the X axis drive motor 12X. As a result, the head unit 13 is moved in the XY direction. It becomes.

  As will be described later, each component supply unit 5 includes a number of component supply units 6 on a feeder base 19 that are detachable side by side. Each component supply unit 6 is equipped with a storage tape C (described later) in which a large number of electronic components are stored in each storage unit at regular intervals. By intermittently feeding the storage tape C, the front end of the component supply unit 6 is mounted. The electronic components are supplied to the component mounting unit 4 one by one.

  The operation based on the mounting data stored in the storage unit of the electronic component mounting apparatus main body 1 is performed by first driving the XY stage 12 so that the head unit 13 faces the component supply unit 6 and then the suction nozzle provided on the mounting head 16. A desired electronic component is picked up (taken out) by lowering 18. Subsequently, after the mounting head 16 is raised, the XY stage 12 is driven to move the electronic component to a position directly above the component recognition camera 14 to recognize the suction posture and the positional deviation with respect to the suction nozzle 18. Next, after the mounting head 16 is moved to the position of the board P on the set table 8 and the position of the board P is recognized by the board recognition camera 17, based on the recognition result by the component recognition camera 14 and the board recognition camera 17, The X-axis drive motor 12X, the Y-axis drive motor 12Y of the XY stage 12 and the θ-axis drive motor 18A of the suction nozzle 18 are corrected and moved to mount the electronic component on the printed circuit board P.

The tape feeding mechanism (tape feeding device) 22 intermittently feeds to the pickup position (suction take-out position), and a cover tape peeling mechanism 20 to be described later for peeling the cover tape Ca of the storage tape C before the pickup position. The

  The storage tape C fed out from the storage tape reel is fed to the pickup position so as to dive under the suppressor 23 disposed in the tape path before the pickup position. The suppressor 23 has an opening for pickup. A slit is formed in the suppressor 23, and the cover tape Ca of the storage tape C is peeled off from the slit and stored in the storage unit 26. That is, the electronic component mounted on the storage tape C is sent to the pickup opening in a state where the cover tape Ca is peeled off, and is picked up by the suction nozzle 18.

The tension of the cover tape Ca is strengthened, and the mounting body 59 resists the urging force of the spring 63. When swinging in the direction, the hanging piece of the operating piece 66 is positioned between the light emitting element 68 and the light receiving element 69, and the detection sensor 67 detects the operating piece 66.

  Accordingly, when the cover tape Ca is peeled off, when the drive motor 42 is driven, the rubber roller 48 and the rubber roller 51 are rotated via the rotating gear 41, gear 43 and gear 47, that is, attached by the spring 55. The urged rubber rollers 51 and 48 are rotated with the cover tape Ca sandwiched therebetween, and the cover tape Ca of the storage tape C is peeled by one pitch from the slit of the suppressor 23, and the parts are supplied without causing slack. The unit 6 is stored in a storage unit 26 provided at the end of the unit 6.

  Reference numeral 45 denotes a label attached to the rear surface of the handle 52 of the component supply unit 6, and a bar code representing a serial number of the component supply unit 6 is written on the label 45. Accordingly, the barcode can be read by a barcode scanner (not shown) even when the plurality of component supply units 6 are attached to the electronic component mounting apparatus main body 1 in close proximity to each other.

  Next, a large number of component supply units 6 are detachably arranged in parallel on the feeder base 19, and the configuration thereof will be described. First, as shown in FIGS. 2, 7, and 8, a pair of guide members 70 having parallel side surfaces 70 </ b> A for guiding the component supply units 6 are provided on the upper surface of the feeder base 19 via a plurality of mounting pins 101. Provided on the bottom surface of the component supply unit 6 is a guided member 71 having a U-shaped cross section in which a concave portion 71A is formed on each outer surface to which the pair of guide members 70 are fitted and guided. Yes. The front end portions of the pair of guide members 70 are inclined upward, and the opposing side surfaces 70B are formed in communication with the parallel side surfaces 70A so that the distance between them becomes farther toward the front. .

  A pair of guide members 70 are provided corresponding to the component supply unit 6. However, since a plurality of component supply units 6 are arranged side by side, the guide member 70 is a guide member 70 of the adjacent component supply unit 6. Also used as

  When the guided member 71 is guided by the pair of guide members 70 and the guided member 71 is slid on the feeder base 19 and moved to attach the component supply unit 6, A front-rear restricting member 72 is provided at the end of the feeder base 19 on the depth side to restrict the position of the component supply unit 6 in the front-rear direction by contacting the guided member 71.

  Further, on the feeder base 19 between the side surfaces 70A of the front portion of the guide member 70, a cylindrical shape that fits in the restriction groove 71B of the guided member 71 and restricts the position of the component supply unit 6 in the left-right direction. Rear left and right restricting pins 73 are provided. Further, a cylindrical front left / right restriction pin 74 that fits in a restriction groove 71B of the guided member 71 in the vicinity of the front / rear restriction member 72 where the guide member 70 is not provided and restricts the position in the left / right direction. Is formed.

  However, the regulation groove 71B of the guided member 71 is engaged with the front left / right regulation pin 74 having a larger diameter than the rear left / right regulation pin 73 and regulates the position of the component supply unit 6 in the left / right direction. When the component supply unit 6 is mounted and fixed on the feeder base 19, the width of the restriction groove 71 </ b> B is restricted to restrict the position in the left and right direction. It is formed to be approximately the same as the diameter of 74 and is formed to be approximately the same as the diameter of the rear left / right regulating pin 73 at a position where the rear left / right regulating pin 73 is fitted.

  In addition, a handle 52 is formed at the rear part of the component supply unit 6, and a lock release lever 79 that is rotatable about the support shaft 78 is provided. The lock release member 81 provided with the abutting portion 81A and rotatably supported with the support shaft 80 as a fulcrum, and the lock release lever 79 are connected to the connection plate 84 rotatably supported by the support shafts 82 and 83. Are connected through. The lock release member 81 is urged to rotate counterclockwise by a spring 85, but counterclockwise rotation is restricted by a restriction pin 86.

  A coil spring 90 is stretched between the attachment member 87 of the feeder base 19 and a locking member 89 that can be rotated with the support shaft 88 as a fulcrum, and is locked with the first lock member 92 provided in the component supply unit 6. A locking member 89 having a possible first locking portion 89A is urged to rotate clockwise. The first lock member 92 includes a roller 92A and a support member 92B on which the roller 92A is provided. A release device that releases the lock between the first lock portion 89A of the lock member 89 and the roller 92A of the first lock member 92 is configured from the lock release lever 79, the lock release member 81, the connecting plate 84, and the like. Is done.

  When the component supply unit 6 is attached to the feeder base 19, the operator holds the handle 52 and moves the component supply unit 6 in the depth direction while the guided member 71 is guided by the guide member 70. While the roller 92A is in contact with the guide portion 89C of the locking member 89 provided in the electronic component mounting apparatus main body 1, the roller 92A is rotated counterclockwise while the roller 92A is rotating in the first locking portion 89A. Will be locked.

  Reference numeral 93 denotes a lock cylinder that constitutes an operating member provided in the electronic component mounting apparatus main body 1. One end of a second lock member 95 that can be rotated about a support shaft 94 is biased by a spring 96 to the rod 93 </ b> A. Has been pressed. When the lock cylinder 93 is actuated and the rod 93A is extended, the second lock member 95 provided in the electronic component mounting apparatus body 1 is rotated counterclockwise, and the other end of the second lock member 95 is rotated. The lock lever 95 </ b> A is in contact with the second locking portion 89 </ b> B of the locking member 89 and restricts the rotation of the locking member 89 in the counterclockwise direction.

  The locking member 89 is provided corresponding to each component supply unit 6, but the locking cylinder 93 and the second lock member 95 are provided corresponding to a plurality of component supply units 6. Therefore, the lock lever 95 </ b> A extends in the direction in which the component supply units 6 are arranged.

  Next, the feeding operation of the storage tape C and the peeling operation of the cover tape Ca will be described. A CPU 110 (to be described later) of the electronic component mounting apparatus main body 1 corresponds to predetermined predetermined component supply units according to mounting data stored in the RAM 111 (data on which position, which direction on the printed circuit board, which electronic component is mounted). 6 tape feeding mechanism 22 is driven, and the storage tape C that stores a predetermined electronic component is intermittently fed once. That is, when the servo motor 28 is driven to rotate forward, the gear 27 and the gear 30 rotate to rotate the rotating shaft 33, and the sprocket 36 rotates intermittently by a predetermined angle in the feed direction via the worm gear 34 and the worm wheel 35. Thus, the storage tape C is intermittently fed through the feed hole.

  When the tape feeding mechanism 22 is driven, the cover tape peeling mechanism 20 is also driven in synchronization with this to peel the cover tape Ca. Subsequently, the servo motor 28 of the tape feeding mechanism 22 stops after intermittently feeding the storage tape C by one pitch (corresponding to one electronic component), but the drive motor 42 of the cover tape peeling mechanism 20 is stopped by the cover tape Ca. However, when the cover tape Ca is tensioned and the attachment body 59 rotates clockwise against the urging force of the spring 63 via the support shaft 58, the detection sensor 67 is actuated. When 66 is detected, the drive motor 42 is stopped.

  Therefore, the electronic component is sent to the pickup position, the electronic component is picked up by the suction nozzle 18, and the next intermittent feeding of the storage tape C and the peeling of the cover tape Ca are performed again. The electronic components sucked and held by the suction nozzle 18 are mounted on the printed circuit board P, but the details are omitted here.

  As shown in FIG. 4, the connecting tape 108A is for connecting the old storage tape C and the new storage tape C together with the connection tapes 108B and 108C to the old storage tape C. And a new cover tape Ca are connected by connecting tapes 18B and 108C.

  Next, a control block diagram of the electronic component mounting apparatus shown in FIG. 3 will be described. 110 is a CPU as a control unit that performs overall control of operations related to electronic component mounting of the electronic component mounting apparatus, 111 is a RAM (random access memory) as a storage device, and 112 is a ROM (read-only memory). ).

  In the RAM 111, mounting data (for each type of printed circuit board P such as X direction, Y direction and angle information in the printed circuit board P and arrangement number information of each component supply unit 6) for each mounting order (for each step number). FIG. 10) is stored, and information on the type (component ID) of each electronic component and the type of each suction nozzle corresponding to the arrangement number (lane number) of each component supply unit 6, that is, component arrangement data ( 11) is stored. Furthermore, component library data (see FIG. 12) configured with items representing the characteristics of electronic components for each component ID is also stored.

  Then, the CPU 110 comprehensively controls operations related to the component mounting operation of the electronic component mounting apparatus according to the program stored in the ROM 112 based on the data stored in the RAM 111. That is, the CPU 110 rotates the X-axis drive motor 12X through the drive circuit 113, drives the Y-axis drive motor 12Y through the drive circuit 114, and rotates the suction nozzle 18 by θ through the drive circuit 115. The driving of the θ-axis motor 18A is controlled, and the driving of the vertical-axis motor 16A for moving the mounting head 16 up and down is further controlled via the drive circuit 116.

  A recognition processing device 117 is connected to the CPU 110 via the interface 118. The recognition processing device 117 performs recognition processing of an image captured by the component recognition camera 14 or the board recognition camera 17. The processing result is sent to the CPU 110. That is, the CPU 110 outputs an instruction to the recognition processing device 117 so as to perform recognition processing (calculation of misalignment amount, etc.) on the image captured by the component recognition camera 14 or the board recognition camera 17 and recognizes the recognition processing result. It is received from the device 117.

  That is, when the amount of positional deviation is grasped by the recognition processing of the recognition processing device 117, the result is sent to the CPU 110, and the CPU 110 detects the X axis drive motor 12X, the Y axis motor 12Y and the suction nozzle 18 of the XY stage 12. The θ-axis motor 18A is corrected and moved so that the electronic component is mounted on the printed circuit board P.

  The monitor 119A as a display device is provided with various touch panel switches 119B as input means for data setting. The operator can perform various settings by operating the touch panel switch 119B. Stored in

  The operation of removing the component supply unit 6 that has been cut off from the feeder base 19 as described above will be described in detail. First, when the operator operates the touch panel switch 119B displayed on the monitor 119A of the electronic component mounting apparatus, the CPU 110 is used for locking. The cylinder 93 is operated. Then, as shown in FIG. 9, the rod 93 </ b> A is retracted, and the second lock member 95 biased by the spring 96 rotates clockwise about the support shaft 94.

  For this reason, the lock lever 95A at the other end of the second lock member 95 is separated from the second lock portion 89B of the lock member 89, and the lock member 89 can be rotated counterclockwise. It becomes.

  Accordingly, for example, when the operator puts the thumb on the rotatable unlocking lever 79 and puts another finger in the handle 52 and pulls the thumb (see FIG. 9), the unlocking lever 79 uses the support shaft 78 as a fulcrum. Rotate clockwise. For this reason, the unlocking member 81 connected via the connecting plate 84 rotates clockwise against the urging force of the spring 85, and the abutting portion 81 </ b> A causes the guide portion 89 </ b> C of the locking member 89 to act as a coil spring. The locking member 89 is pushed up against the urging force 90, and the locking member 89 is rotated counterclockwise. For this reason, the roller 92A comes off from the first locking portion 89A (the locking is released).

  Thereafter, the operator pulls the component supply unit 6 in the forward direction while holding the handle 52, so that the guided member 71 can be moved in the forward direction while being guided by the guide member 70. The component supply unit 6 can be removed (see FIGS. 7 and 8).

  Then, the storage tape C is fed out to some extent from the storage tape reel storing the new storage tape C, and the new storage tape C is loaded into the component supply unit 6 in a state of being laid on the work table. In this case, the suppressor 23 serving as a peeling fulcrum of the cover tape Ca of the storage tape C is rotated upward, and the above described via the loading opening 39 communicating with the tape passage 38 from the side of the component supply unit 6. The storage tape C is loaded into the component supply unit 6.

  Then, the cover tape Ca peeled off from the leading portion of the storage tape C is taken out from the bottom through the slit of the suppressor 23, and the rollers 60, 64 of the tension applying body 65 and the upper wall of the mounting body 59 are Then, the operator swings the operating body 54 with the support shaft 53 as a fulcrum against the urging force of the spring 55 and is positioned between the rubber rollers 48 and 52 to store the tip portion. Guide to section 26. In this case, by operating the touch panel switch 119B displayed on the monitor 119A, the CPU 110 drives the drive motor 42 of the cover tape peeling mechanism 20, and the rubber roller 48 and the gear 47 via the gear 41, the gear 43, and the gear 47, When the rubber roller 51 is rotated and tension is applied to the cover tape Ca, and the attachment body 59 rotates clockwise via the support shaft 58, the detection motor 67 detects the operating piece 66, and the drive motor 42 is moved. Stop.

  On the other hand, the storage tape C from which the cover tape Ca has been peeled is engaged with the teeth of the sprocket 36 in the feed hole so that the top of the storage tape C is slightly removed from the front end of the component supply unit 6 and the suppressor 23 is rotated downward to hold the storage tape C from above to prevent the storage tape C from being detached from the teeth of the sprocket 36.

  In this way, the loading operation is completed by attaching the component supply unit 6 loaded with the storage tape C to the feeder base 19.

  The operation of attaching the component supply unit 6 to the feeder base 19 will be described below. First, the operator holds the handle 52 and provides a pair of guide members 70 provided on the feeder base 19 and the bottom surface of the component supply unit 6. The guided member 71 is fitted. In this case, the front side ends of the pair of guide members 70 are inclined upward, and the opposing side surfaces 70B are formed so that the distance between them becomes farther toward the front. It can be easily fitted in the recess 71A of the guided member 71 provided on the bottom surface of the component supply unit 6.

  After the fitting, when the operation of pushing the component supply unit 6 in the depth direction is performed, the guided member 71 is guided by the pair of guide members 70, and the guided member 71 slides (slides) on the feeder base 19. However, the component supply unit 6 moves.

  Eventually, at the time of this movement, the rear left / right regulating pin 73 moves while fitting into the regulating groove 71B of the guided member 71, and further moving, the front left / right regulating pin 74 becomes wider in the regulating groove 71B. The part and the rear left and right restriction pin 73 are fitted to the narrowed part of the restriction groove 71B. Further, when the guide member 71 is further moved in the depth direction, the guided member 71 comes into contact with the front-rear regulating member 72 at the end of the feeder base 19 on the depth side and cannot move.

  Accordingly, the component supply unit 6 is positioned by restricting the left / right direction of the component supply unit 6 by the rear left / right restriction pin 73 and the front left / right restriction pin 74 and by the front / rear restriction member 72.

  In the middle of the movement of the component supply unit 6 in the depth direction from the state shown in FIG. 2, the roller 92A comes into contact with the guide portion 89C of the locking member 89 as shown in FIG. The roller 92A is locked to the first locking portion 89A while being rotated clockwise.

  Thereafter, when the operator operates the touch panel switch 119B displayed on the monitor 119A of the electronic component mounting apparatus, the CPU 110 operates the lock cylinder 93 and rotates the second lock member 95 counterclockwise by the extended rod 93A. The lock lever 95A at the other end of the second lock member 95 is brought into contact with the second lock portion 89B of the lock member 89, and the rotation of the lock member 89 in the counterclockwise direction is restricted. (See FIG. 6). As a result, the component supply unit 6 is securely locked, and the component supply unit 6 can be mounted and fixed on the feeder base 19.

  By the way, the old storage tape C and the new storage tape C with a reduced number of electronic parts are connected by the connecting tapes 108A, 108B and 108C. If the cover tape Ca is in a state of being tensioned for a long time, that is, the parts supply If the unit 6 is not used for a long time, sometimes the bonding portions of the connecting tapes 108A, 108B and 108C are peeled off, and the old storage tape C and the new storage tape C are separated.

  Therefore, as a first embodiment, the timer 120 measures the time when the component supply unit 6 is not used, and when the non-use time elapses, for example, 30 minutes, the detection sensor 67 detects and drives the operating piece 66. From the state where the motor 42 is stopped and the cover tape Ca is tensioned to some extent, the drive motor 42 is reversely rotated until the detection sensor 67 does not detect the operating piece 66 to loosen the tension.

  Specifically, the timer 120 starts counting from the start or stop of operation of the servo motor 28 of the tape feed mechanism 22, that is, from when the CPU 110 issues a drive command to the servo motor 28 via the drive circuit 121. Alternatively, when 30 minutes have elapsed since the encoder (not shown) has detected a predetermined rotation, the detection sensor 67 detects the operating piece 66 and the drive motor 42 is stopped, and the cover tape Ca is somewhat tensioned. Until the detection sensor 67 does not detect the operating piece 66, the drive motor 42 is reversely rotated to loosen the tension.

  Next, a second embodiment will be described. As described above, in order to connect the old storage tape C and the new storage tape C with a reduced number of electronic components with the connection tapes 108A, 108B and 108C, In order to switch the model, the operation of removing the component supply unit 6 from the feeder base 19 is detected, and the drive motor is detected until the detection sensor 67 does not detect the operating piece 66 from a state where the cover tape Ca is tensioned to some extent. 42 is reversely rotated to loosen the tension.

  Specifically, when the operator operates the touch panel switch 119B displayed on the monitor 119A when performing the work of removing the component supply unit 6, as described above, the CPU 110 operates the locking cylinder 93 to move the rod 93A. Since this operation is detected by the detection switch 123 such as a micro switch, the CPU 110 that has received this detection signal reversely rotates the drive motor 42 until the detection sensor 67 does not detect the operating piece 66, thereby applying the tension. Loosen. The detection switch 123 detects that the rod 93A has been retracted by operating the lock cylinder 93. However, the operation state of the lock release lever 79 accompanying the removal work of the component supply unit 6 is not limited to this. Various embodiments are possible, such as grasping the change of the component supply unit 6 that is removed from the feeder base 19 and moved.

  In the above embodiment, the operation of removing the component supply unit 6 from the feeder base 19 is detected. However, a component supply carriage (see FIG. (Not shown) can be attached to and detached from the electronic component mounting apparatus main body 1 so that the CPU 110 receiving the detection signal detects the operation of removing the component supply carriage from the electronic component mounting apparatus main body 1. The drive motor 42 may be rotated in the reverse direction until the detection sensor 67 does not detect the operating piece 66 to loosen the tension.

  Next, a third embodiment will be described. In this embodiment, for example, an operation switch 124 is provided in the vicinity of the label 45 attached to the rear surface of the handle 52 of the component supply unit 6, and when it is detected that the operator has operated the operation switch 124, this detection signal is output. The received CPU 110 rotates the drive motor 42 in the reverse direction until the detection sensor 67 no longer detects the operating piece 66 to loosen the tension. The operation switch 124 is not limited to the above embodiment, and may be provided in any form, for example, a touch panel switch 119B displayed on the monitor 119A of the electronic component mounting apparatus.

  Next, a fourth embodiment will be described. In this embodiment, for example, when some trouble occurs in the electronic component mounting apparatus and the electronic component mounting apparatus is abnormally stopped, the timer 125 counts the abnormal stop time. The drive motor 42 is reversely rotated until the detection sensor 67 of the supply unit 6 does not detect the operating piece 66 to loosen the tension.

  Next, a fifth embodiment will be described. In this embodiment, for example, when the model of the printed circuit board is switched, the unused component supply unit 6 is connected to the feeder base 19 or the component based on the mounting data (see FIG. 10) related to the mounting of the electronic component on the new printed circuit board. When mounted on a supply carriage (not shown), the drive motor 42 is used until the detection sensor 67 does not detect the operating piece 66 in order to loosen the tension of the cover tape Ca of the unused component supply unit 6. The tension is loosened by rotating in reverse.

  Specifically, in the RAM 111, the type of the printed circuit board P such as the X direction, Y direction and angle information in the printed circuit board P and the arrangement number information of each component supply unit 6 for each mounting order (for each step number). Mounting data (see FIG. 10) is stored for each, and information on the type (component ID) of each electronic component and the type of each suction nozzle corresponding to the arrangement number (lane number) of each component supply unit 6; That is, since component arrangement data (see FIG. 11) is stored, when a printed circuit board on which an electronic component is to be mounted is selected by operating the touch panel switch 119B displayed on the monitor 119A and automatic operation is started. The component supply unit 6 that supplies electronic components that are not mounted on the selected printed circuit board is mounted on the feeder base 19. Rukoto is seen.

  Therefore, in order to loosen the tension of the cover tape Ca of the storage tape C mounted on the unused component supply unit 6, the CPU 110 reversely rotates the drive motor 42 until the detection sensor 67 does not detect the operating piece 66. Loosen.

  As described above, when the state in which the component supply unit 6 is not used continues for a long time, the bonded portions of the connecting tapes 108B and 108C are sometimes peeled off, and the cover tape Ca of the old storage tape C and the cover tape Ca of the new storage tape C However, the separation can be prevented by loosening the tension of the cover tape Ca of the component supply unit 6.
