Description

  The present invention intermittently feeds electronic components stored in a component storage portion formed on a carrier tape of a storage tape to a component pick-up position by a tape feeder, and opens a cover tape covering the upper surface opening of the component storage portion in the suppressor. The present invention relates to an electronic component mounting apparatus provided with a component supply device that enables removal of an electronic component that has been peeled off by a peeling device through a slit and has been sent to the component pick-up position, and that is capable of feeding the peeled cover tape. .

As disclosed in, for example, Patent Document 1, the component supply device, when a storage tape is fed by a tape feeding device, a peeling lever biased by a spring swings upward to peel the cover tape. Therefore, the movement of the peeling lever is detected, and the collecting motor is driven to collect the peeled cover tape. When the remaining number of electronic components decreases, splicing is performed by adding a storage tape that stores electronic components of the same type. In this case, since the splicing tape is applied, wrinkles or peeling of the cover tape is caught on the suppressor, and the suppressor The cover tape may be caught between the carrier tape and the carrier tape. Accordingly, when the entrainment occurs, the tension of the cover tape is not loosened even when the storage tape is fed by the tape feeding device, so that the tensioning state is maintained without the peeling lever swinging. For this reason, in the past, this was detected by a detection device to notify the abnormality and stop the mounting operation.

  Next, the component supply unit 6 will be described with reference to FIG. The component supply unit 6 includes a unit frame 21 which is a unit main body, and a storage tape C which is sequentially wound in a state of being wound around a storage tape supply reel which is rotatably mounted on the component supply unit 5. A tape feeding mechanism (tape feeding device) 22 that intermittently feeds to the component 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 in front of the pickup position PU.

  The storage tape C fed out from the storage tape supply reel is fed to the pickup position PU so as to dive under the suppressor 23 disposed in the tape path before the pickup position PU. The suppressor 23 is provided with an opening 23A for pickup. A slit 23B is also formed, and the cover tape Ca of the storage tape C is peeled off from the carrier tape Cc by the cover tape peeling mechanism 20 through the slit 23B and stored in the cover tape storage portion 26 having the storage space S. The That is, in a state where the cover tape Ca is peeled off by the cover tape peeling mechanism, the electronic component D mounted on the component storage portion Cb of the carrier tape Cc is sent to the pickup position PU by the feeding mechanism 22 and is sucked through the opening 23A. It is picked up by the nozzle 18.

  Next, the tape feeding mechanism 22 will be described. The tape feeding mechanism 22 has a first belt having a timing belt stretched between a servomotor 25 (see FIG. 6), which is a drive source capable of forward and reverse rotation, having a first gear on its output shaft. A rotary shaft (not shown) having two gears at one end and rotatably supported by a support via a bearing, and a worm wheel 28 meshing with a worm gear provided at an intermediate portion of the rotary shaft, The sprocket 27 is configured to mesh with a feed hole formed in the storage tape and feed it. The worm wheel 28 and the support shaft 29 of the sprocket 27 pass through the intermediate partition body of the unit frame 21.

  Accordingly, when the servo motor 25 is driven to rotate in order to supply the electronic components in the storage tape C in the component supply unit 6, only the rotation shaft is rotated by the rotation of the first and second gears via the timing belt. The storage tape C is intermittently fed through the feed hole of the storage tape C by intermittently rotating the sprocket 27 by a predetermined angle in the feed direction through the worm gear and the worm wheel 28.

  The suppressor 23 has a substantially U-shaped cross section from both vertical pieces serving as support portions and a horizontal piece that holds the storage tape C engaged with the teeth of the sprocket 27 so as not to come off. When the lock is released, the vertical piece is supported so as to be rotatable about the rear pin 30 as a fulcrum. When the front portion of the suppressor 23 is locked, the suppressor 23 is urged downward, and the suppressor 23 constantly presses the carrier tape Cc after the storage tape C and the cover tape are peeled against the tape guide chute 24. It acts so that the feed hole of the carrier tape Cc is not detached from the tape feed teeth of the sprocket 27.

  In the state where the suppressor 23 serving as a peeling fulcrum of the cover tape of the storage tape C is rotated and held upward, the side of the component supply unit 6 passes through the loading opening 31 formed in the unit frame 21. The storage tape can be loaded into the component supply unit 6.

  Next, the cover tape peeling mechanism 20 will be described with reference to FIGS. The cover tape peeling mechanism 20 has a worm gear 41 on its output shaft and feeds a cover tape that can be rotated forward and backward (hereinafter referred to as a recovery drive motor) 42, and can rotate via a support shaft 46. 41, a gear 43 and a first spur gear (not shown) that engage with the gear 41, and a second spur gear 52 that engages with the first spur gear and a gear 47 that are rotatable via the support shaft 50 and are fixed to the unit frame 21. A support body 44 and a gear 51 that can rotate through a support shaft 56 and mesh with the gear 47 are supported by the unit frame 21 through a support shaft 53 so as to be swingable. The support pin 6 fixed to the bottom surface 59A of the operating body 54 urged so as to engage with the pin 51 and the peeling lever 59 that can swing through the support shaft 58 with the roller 60 interposed therein. The release lever 59 is biased counterclockwise (in FIG. 2) by a spring 63 that is wound around and attached between the mounting piece 62 fixed to the unit frame 21 and the other end of the release lever 59. And a tension applying body 65 for applying tension to the cover tape Ca guided by the roller 60.

  Reference numeral 66 denotes an operating piece which is a detected portion having an L-shaped cross section provided at the lower end of the side wall of the peeling lever 59. The tension of the cover tape Ca is strengthened and the spring 63 is resisted against the urging force of the spring 63. When the peeling lever 59 swings in the clockwise direction in FIG. 2, the operating piece 66 is positioned between the light emitting element 68 and the light receiving element 69, and the detection sensor 67 for detecting the cover tape tension as the detecting device is operated. 66 will be detected.

  When collecting the cover tape Ca, when the drive motor 42 is driven, the worm gear 41 is rotated, and the gear 43, the gear 47, and the gear 51 are rotated, that is, urged by the spring 55 to be urged by the gear 47 and the gear. 51 rotates with the cover tape Ca interposed therebetween, and the cover tape Ca is housed in the cover tape housing portion 26 provided at the end of the component supply unit 6 without being loosened.

  Further, the gear 47 and the gear 51 have the same shape, form two teeth at intervals, and make the teeth 47A and 51A rounded. By setting it as such a shape, a crease | fold is not formed in the cover tape Ca after peeling which passed between the gear 47 and the gear 51. FIG.

  A scraper 48 is fixed to the upper wall of the operating body 54 with screws 49 so that the peeled cover tape Ca is attached along the gear 51 and does not go upward. Therefore, the regulation guide portion 48A formed to project from one side surface of the scraper 48 is fixed so as to enter the groove 51B while the two teeth are formed.

  When the component supply unit 6 is attached to the feeder base 19, the guided member 71 is guided by a pair of guide members provided on the feeder base 19 by the operator holding the handle 70. While moving in the depth direction, the roller 72 is locked to a locking member provided in the electronic component mounting apparatus main body 1. When the guided member 71 is guided by the pair of guide members and the guided member 71 is slid on the feeder base 19 and moved to attach the component supply unit 6, the feeder is moved. A front-rear restricting member (not shown) that restricts the position of the component supply unit 6 in the front-rear direction when the guided member 71 abuts is provided at the depth side end of the base 19.

  Then, the lower end of the open / close door 73, which is a magnetic body that closes the external opening forming the storage space S of the cover tape storage 26, is attracted to the magnet provided in the external opening so as to wind the support shaft 74. It is comprised in this way and is supported so that rotation is possible.

  Next, a control block diagram of the electronic component mounting apparatus will be described with reference to FIG. 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). ).

  The RAM 111 has 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). Further, the electronic component type (component ID) corresponding to the arrangement number of each component supply unit 6 and the information (component arrangement data) of each suction nozzle type are stored. Furthermore, component library data composed of items representing the characteristics of the electronic component 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 controls the driving of the X-axis drive motor 12X, the Y-axis drive motor 12Y, the θ-axis drive motor 18A, and the vertical axis motor 18B via the drive circuit 113.

  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 displacement is grasped by the recognition processing of the recognition processing device 117, the result is sent to the CPU 110, and the CPU 110 drives the X-axis drive motor 12X, the Y-axis drive motor 12Y and the θ-axis drive of the XY stage 12. Control is performed so that the motor 18A is corrected and moved to mount the electronic component on the printed circuit board P.

  The monitor 119 as a display device is provided with various touch panel switches 120 as input means for data setting, and various settings can be performed by an operator operating the touch panel switch 120. The setting data is stored in the RAM 111. Stored in

  With the above configuration, the operation will be described below with reference to FIGS. First, the CPU 110 turns off the READY signal of the component supply unit 6 and performs the tension recovery process of the cover tape Ca before the feeding operation of the storage tape C. That is, as shown in FIG. 8, first, the detection sensor 67 for detecting the cover tape tension is turned off, ie, the light-transmitting state where the operating piece 66 is not positioned between the light emitting element 68 and the light receiving element 69. Determine. In this case, normally, since there is a predetermined tension and the light is blocked and turned on, the routine returns to the routine of FIG. 7, but if it is determined that the predetermined tension is not applied, the recovery drive motor 42 is recovered. CPU 110 controls to rotate normally.

  In order to monitor the drive time of the drive motor 42, a monitoring timer 121 is set. By the forward rotation of the drive motor 42, the peeling lever 59 swings clockwise (in FIG. 2) with the support shaft 58 as a fulcrum against the urging force of the spring 63. When the proper tension can be recovered, the detection sensor 67 is shielded from light by the operating piece 66. When the detection sensor 67 is determined to be on, the forward drive of the drive motor 42 is stopped and the monitoring timer 121 is cleared. Return to the routine. However, at this time, when the detection sensor 67 cannot be turned on because the proper tension state cannot be recovered and the monitoring timer 121 expires after a predetermined time, the forward driving of the drive motor 42 is stopped and the monitoring timer 121 is stopped. Is cleared, the CPU 110 controls to abnormally register in the RAM 111, and returns to the routine of FIG. The contents of the abnormality in this case are considered that the storage tape C is not loaded in the component supply unit 6 or that the cover tape Ca is cut.

  When the cover tape tension recovery process before the feeding operation of the storage tape C is performed, the CPU 110 next determines whether or not an abnormality has occurred (there is an abnormality registration). Control (not shown) is performed so as to notify abnormality through visual or auditory sense, and control is performed so as to stop the operation state of the electronic component mounting apparatus. Therefore, the operator understands that it is abnormal, and loads the storage tape into the component supply unit 6 or connects it because the cover tape is broken, returns to the normal state, and resumes operation. be able to.

  When the cover tape tension recovery process is performed and it is determined that the abnormality is not registered, the forward transfer operation of the storage tape by the forward rotation drive of the servo motor 25 is started, as shown in FIG. Therefore, the detection of the tension of the cover tape and the recovery control are performed. That is, first, it is determined again whether or not the detection sensor 67 for detecting the cover tape tension is in the light-transmitting state. When the peeling lever 59 swings counterclockwise to peel off the cover tape and it is determined that the cover tape has become loose, the cover tape collecting drive motor 42 is rotated in the forward direction to remove the cover tape from the cover tape storage section. The CPU 110 controls so as to be accommodated in the H.26.

  Then, in order to monitor the drive time of the drive motor 42, a monitor timer 121 is set, and the cover tape loosening history is stored in the RAM 111. Next, since the separation lever 59 swings clockwise (in FIG. 2) by the normal rotation drive of the recovery drive motor 42, the detection sensor 67 is shielded by the operating piece 66 and determined to be on. Then, the forward drive of the drive motor 42 is stopped and the monitoring timer 121 is cleared, and the routine returns to the routine of FIG. However, even if the recovery drive motor 42 is rotated forward, the proper tension state cannot be recovered and the detection sensor 67 is not turned on. If the monitoring timer 121 expires after a predetermined time has elapsed, the drive motor 42 rotates forward. The driving is stopped and the monitoring timer 121 is cleared, and the CPU 110 performs control so as to register the abnormality in the RAM 111, and returns to the routine of FIG. The content of the abnormality in this case is considered that the storage tape is not loaded in the component supply unit 6 or the cover tape is cut.

  Thus, after the storage tape feeding operation is started, the cover tape tension detection is monitored and recovered, but the storage tape fed out from the storage tape supply reel is in front of the pickup position. The tape is fed by the tape feeding mechanism 22 while diving under the suppressor 23 disposed in the tape path. When the storage tape is fed, the peeling lever 59 swings counterclockwise (in FIG. 2) by the urging force of the spring 63, and the cover tape Ca is peeled from the carrier tape Cc. That is, as the feeding operation of the storage tape C of the tape feeding mechanism 22 continues, the peeling lever 59 swings counterclockwise about the support shaft 58 by the biasing force of the spring 63, and the cover tape Ca is As a result, the amount of compression of the spring 63 gradually decreases, and the tensile tension force cannot be maintained.

  When the peeling lever 59 swings counterclockwise, when the operating piece 66 is not positioned between the light emitting element 68 and the light receiving element 69 and enters a light-transmitting state, the detection sensor 67 does not detect the operating piece 66. Therefore, the tape feeding operation is finished.

  In FIG. 7, if the tape feeding operation is completed and the drive motor 42 is stopped, the CPU 110 next determines whether or not an abnormality has occurred (there is an abnormality registration). Control is performed so as to notify the abnormality by the notification means, and control is performed so as to stop the operation state of the electronic component mounting apparatus. When it is determined that the abnormality is not registered, the CPU 110 generates looseness of the cover tape stored in the RAM 111. The history is checked (see FIG. 10).

  That is, in FIG. 10, if the cover tape slack occurrence history memory is on, the cumulative feed amount accumulated value of the counter 123 is cleared, the cumulative feed amount is set to zero, and if it is not on, the cumulative feed amount is set to zero. The current feed amount is added, the cumulative feed amount is integrated, and the process returns to the routine of FIG.

  In FIG. 7, the CPU 110 checks the cover tape loosening history to determine whether or not the cover tape has been entangled. That is, it is determined whether or not the cumulative feed amount is larger than the winding determination feed amount. If it is not larger, the READY signal of the component supply unit 6 is turned on. If it is larger, the cover tape winding state forcible return processing shown in FIG. I do. When the cumulative feed amount is larger than the predetermined winding determination feed amount, the cover tape Ca is wound between the suppressor and the storage tape C as shown in FIG. That is, when the remaining number of electronic components decreases, splicing is performed by adding a storage tape C that stores the same type of electronic components. In this case, since the splicing tape is applied, wrinkles or peeling of the cover tape Ca is caused on the suppressor 23. It is considered that the cover tape Ca is caught between the suppressor 23 and the carrier tape Cc.

  That is, when the cover tape is entangled, the counter 124 for counting the number of reverse feed (reverse) drive of the storage tape is set to “2”, and the reverse feed (reverse) drive of the storage tape is started. Reverse the specified pitch feed. When the reverse feed (reverse rotation) drive of the storage tape by the reverse rotation drive of the servo motor 25 is completed, the operation piece 66 is in a state where it is still tensioned by the reverse feed (reverse rotation) of the storage tape. If the detection sensor 67 is not in the light-transmitting state, the counter 124 is decremented by “1”, and then it is checked whether the content of the counter 124 becomes “0”. Since the content of the counter 124 is “1”, the reverse feed (reverse) drive of the storage tape is started again, the reverse of the designated pitch feed is performed, and the reverse feed (reverse) drive of the storage tape is completed. If the detection sensor 67 is not in the light-transmitting state, the counter 124 is decremented by “1” and then it is checked whether the content of the counter 124 becomes “0”. The CPU 110 performs abnormality registration in the RAM 111. That is, it is determined that the process of forcibly pulling back the cover tape that has been wound has been restored but has failed, and the routine returns to the routine of FIG.

  On the other hand, the above-described winding is canceled by the reverse or reverse drive of the storage tape for the first time or again, and the peeling lever 59 swings counterclockwise, so that the detection sensor 67 enters a light-transmitting state. Then, as shown in FIG. 14, when the stretched state of the cover tape Ca is eliminated, the CPU 110 drives the cover tape recovery drive motor 42 to rotate forward and sets the monitoring timer 121. The worm gear 41, the gear 43, the gear 47, and the gear 51 are rotated by the forward drive of the drive motor 42, and the gear 47 and the gear 51 are rotated with the cover tape Ca sandwiched between them by the spring 55, The tension of the loose cover tape Ca is restored to an appropriate tension (see FIG. 15), and the cover tape Ca is stored in the cover tape storage section 26.

  Then, when the drive motor 42 is driven to rotate forward, the gear 47 and the gear 51 rotate with the cover tape Ca sandwiched between them by being urged by the spring 55, and the cover tape Ca of the storage tape C gradually becomes an appropriate tension. When the peeling lever 59 swings in the clockwise direction and the operating piece 66 is positioned between the light emitting element 68 and the light receiving element 69 in a light shielding state, the forward drive of the drive motor 42 is stopped. The monitoring timer 121 is cleared and the routine proceeds to the routine of FIG.

  That is, when the servomotor 25 is driven to rotate forward to start the feeding operation of the storage tape C, the storage tape C is fed after the proper tension of the cover tape Ca is recovered, and the electronic component D is sent to the pickup position PU. Next, the detection sensor 67 determines whether or not a light transmission state has occurred due to the looseness of the cover tape. However, even if the feeding operation of the storage tape C is started, the light transmission state is generated. If not, it is determined whether or not the light transmission state has occurred until it is determined that the feeding operation of the storage tape C is completed and the cover tape collecting drive motor 42 is stopped.

  When it is determined that the light transmission state has occurred, if the drive motor 42 is not driven, the drive motor 42 is driven to rotate forward, the monitoring timer 121 is set, and the proper tension is restored. When the detection sensor 67 detects that the light shielding state has occurred, the forward drive of the drive motor 42 is stopped, the monitoring timer 121 is cleared, the feeding operation of the storage tape C is completed, and the cover tape collecting drive motor is completed. Since it is determined that 42 is stopped, the routine returns to the routine of FIG.

  However, if the monitoring timer 121 is set but the detection sensor 67 cannot detect that the light-shielding state has occurred without recovering the proper tension, when the monitoring timer 121 elapses for a predetermined time, the drive motor The forward rotation driving of 42 is stopped, the monitoring timer 121 is cleared, the CPU 110 registers the abnormality in the RAM 111, and the process returns to the routine of FIG.

  In the description of FIG. 11, as described above, after the drive motor 42 performs the reverse rotation drive once or twice to loosen the tension of the cover tape, the drive motor 42 is driven forward and the monitoring timer 121 is set. However, if the set monitoring timer 121 is not recovered to the proper tension and the time is up after a predetermined time has elapsed, the forward driving of the drive motor 42 is stopped and the monitoring timer 121 is cleared. Then, the control returns to the routine of FIG. The content of the abnormality in this case is considered to be a state where the cover tape is cut.

  As described above, when the forcible return processing of the cover tape winding state shown in FIGS. 11 and 12 is performed, as shown in FIG. If the abnormality is registered and the abnormality is registered, control is performed so that the abnormality is notified by the notification means, and the operation state of the electronic component mounting apparatus is stopped. The notification in this case includes the fact that the forced recovery was attempted but could not be resolved. If the winding is eliminated, the CPU 110 turns on the READY signal of the component supply unit 6 and ends the storage tape feeding operation.

  Accordingly, the electronic component D mounted in the component storage portion Cb of the carrier tape Cc is sent to the pickup position PU by the feeding mechanism 22 and the cover tape Ca is peeled off by the cover tape peeling mechanism 20 through the slit 23B, thereby opening the pickup. It is picked up by the suction nozzle 18 through 23A and mounted on the printed circuit board P.
