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. A component that can be taken out by the peeling device through the slit and removed from the electronic component sent to the component take-out position, and the peeled cover tape is collected by the collecting device to the cover tape collecting and storing unit. The present invention relates to an electronic component mounting apparatus including a supply device.

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 in the cover tape collecting and storing unit. When the remaining number of electronic components decreases, splicing is performed by adding storage tapes that store electronic components of the same type. At this time, the cover tape collected in the cover tape collection storage unit is cut out, removed, and discarded. Thus, processing is performed so as to reduce the amount of cover tape in the cover tape collecting and storing unit.

Normally, the XY stages 12 and 12 of both the component mounting parts 4 and 4 are alternately operated.

  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 along the beam 12A by the X-axis drive motor 12X. It will move in the XY direction.

  Each component supply unit 5 includes a component supply unit 6 which is a large number of component supply devices on a feeder base 19 so as to be detachable side by side. Each component supply unit 6 is provided with a storage tape C in which a large number of electronic components D are stored in the respective component storage portions Cb of the carrier tape Cc at regular intervals, and the storage tape C is intermittently fed and the cover tape Ca. Is peeled and the electronic components D are sent to the component suction position, whereby the electronic components D are supplied one by one from the tip of the component supply unit 6 to the component mounting portion 4.

  In the operation based on the mounting data of the electronic component mounting apparatus main body 1, first, the XY stage 12 is driven, the head unit 13 faces the component supply unit 6, and then the suction nozzle 18 provided on the mounting head 16 is lowered. A desired electronic component D is picked up (taken out) from the carrier tape Cc from which the cover tape Ca has been peeled off.

  Next, the component supply unit 6 will be described with reference to FIGS. 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 before the pickup position of the electronic component. The

  As shown in FIG. 6, the storage tape C fed out from the storage tape supply reel is fed to the pickup position PU so as to lie under the suppressor 23 disposed in the tape path in front of 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 from the carrier tape Cc by the cover tape peeling mechanism 20 through the slit 23B, and stored in the cover tape collecting and storing part 26 having the storage space S. Is done. 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 feed mechanism 22 and is adsorbed 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. 7) that 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. Accordingly, when the detection sensor 67 for detecting the cover tape tension detects the operating piece 66, a predetermined tension is applied to the cover tape, and when the operating piece 66 is not detected, a predetermined tension is not applied to the cover tape. 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 collecting and housing section 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, an operator holds the handle 70 and the guided member 71 is guided by a pair of guide members provided on the feeder base 19. Is moved in the depth direction, and 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 that forms the storage space S of the cover tape collecting and storing part 26, is attracted to the magnet provided in the external opening so as to wind the support shaft 74. It is comprised so that it can rotate and is supported.

  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 driving of the X-axis drive motor 12X, the Y-axis drive motor 12Y, the θ-axis drive motor 18A, the vertical axis motor 18B, and the like 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

  Because of the above configuration, the operation will be described below based on the flowchart of FIG. First, the CPU 110 determines whether or not a tape feed command for the storage tape C has been generated (ON). If it is determined that it has been generated, the CPU 110 controls to start driving the servo motor 25 for tape feed.

  Accordingly, the feeding operation of the storage tape by the drive of the servo motor 25 is started, and the detection of the tension of the cover tape and the collection control are performed thereafter. That is, first, the CPU 110 determines whether or not the cover tape tension detection sensor 67 is in the light-off state. In other words, the detection sensor 67 for detecting the cover tape tension determines whether or not the operating piece 66 is in the light-transmitting state where the operating piece 66 is not positioned between the light emitting element 68 and the light receiving element 69.

  In this case, just after the feeding operation is started, the cover tape Ca has tension and no looseness occurs. Therefore, the detection sensor 67 detects the light shielding state, and the CPU 110 turns off the cover tape collecting drive motor 42 ( And the monitoring timer 121 for the operation time of the recovery drive motor 42 is reset.

  Next, it is determined whether or not the tape feed servomotor 25 is in operation. Since the tape feed servomotor 25 is in operation, the operation returns to the determination operation as to whether or not the detection sensor 67 described above is in a light-transmitting state. Then, along with the feeding operation of the storage tape C driven by the servo motor 25, the peeling lever 59 swings counterclockwise to peel the cover tape Ca, and the cover tape is loosened. If it is determined that the light state is detected, it is determined whether or not the cover tape recovery drive motor 42 is in operation, and is not in operation. Therefore, the recovery drive motor 42 operates and the operation time of the recovery drive motor 42 is increased. A monitoring timer 121 for timing is set.

  Next, it is determined whether or not the time measured by the monitoring timer 121 for the operation time of the recovery drive motor 42 has exceeded a full notice determination time (arbitrarily set and can be changed). If it is determined that it does not exceed, a time-out determination time for an abnormal stop (which is arbitrarily set) is set to be longer than the full notice determination time by the monitoring timer 121. It is determined whether or not the change has been exceeded. In this case, if it does not exceed, it is determined again whether or not the tape feed servo motor 25 is operating. If not, it is determined whether or not the recovery drive motor 42 is operating and is operating. The operation returns to the operation for determining whether or not the detection sensor 67 is in the light-transmitting state and is in the OFF state as described above, but when the cover tape is stored in the cover tape recovery storage portion 26 by the operation of the recovery drive motor 42. Then, the peeling lever 59 swings clockwise, the cover tape Ca is not loosened, tension is generated, and the detection sensor 67 detects the light shielding state.

  Accordingly, the CPU 110 turns off (stops) the cover tape collection drive motor 42 and resets the collection drive motor 42 operating time monitoring timer 121. Then, it is determined again whether or not the tape feed servo motor 25 is in operation. Since it is not in operation, it is next determined whether or not the recovery drive motor 42 is in operation. However, since there is no abnormality registration, the process returns to the determination of whether or not the tape feed command for the storage tape C for taking out the next electronic component has been issued.

  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.

  By the way, the feeding operation of the storage tape as described above, the monitoring of the tension detection of the cover tape, and the recovery control are repeated. In this case, as the cover tape is collected, the cover tape is accommodated in the cover tape collecting / accommodating portion 26 by the operation of the collecting drive motor 42, but the amount of the cover tape collected and accommodated increases. As a result, it becomes difficult to store the cover tape in the cover tape collecting and storing unit 26 gradually. For this reason, the transition time from the state where the operating piece 66 is not located between the light emitting element 68 and the light receiving element 69 to the light shielding state is gradually increased, and the predetermined level of the detection sensor 67 for detecting the cover tape tension is detected. The time until the tension can be detected becomes longer, and as a result, the operation time of the recovery drive motor 42 becomes longer. In this case, it is timed by the monitoring timer 121 that the time measured for the operation time of the recovery drive motor 42 has exceeded the full notification time.

  That is, as described above, with the feeding operation of the storage tape C driven by the servo motor 25, the peeling lever 59 swings counterclockwise to peel the cover tape Ca, and the cover tape is loosened. If the detection sensor 67 determines that the light transmission state has been detected, it is determined whether or not the recovery drive motor 42 is in operation and is not in operation, so that the recovery drive motor 42 operates and the recovery drive motor 42 operates. A monitoring timer 121 for measuring the time is set, and it is timed that the monitoring timer 121 has exceeded the full notification time for the recovery drive motor 42.

  Then, the full notice notification flag is turned on, and the CPU 110 stores the full notice information in the RAM 111 and displays the full notice information on the monitor 119, and the inside of the cover tape collecting and storing unit 26 of the component supply unit 6. Informs that the amount of cover tape collected is full.

  Note that this notification is not limited as long as it is a notification means that can notify the worker visually or audibly. That is, when the component supply unit 6 is a dual lane feeder having dual lanes that can supply electronic components in parallel using two storage tapes, for example, on the upper surface of the handle 70 of the component supply unit 6. When one lane (right side) is in a full notice state in the liquid crystal display section 70A (see FIG. 2) provided, as shown in FIG. 9, the lower part of the right 7-segment display unit corresponding to one lane Is controlled to blink every 0.5 seconds, and when the other lane (left side) is in the full notice state, as shown in FIG. 10, the left 7-segment display unit corresponding to the other lane The lower part is controlled to blink every 0.5 seconds, and when both dual lanes are in full notice state, as shown in FIG. 11, the lower parts of the left and right 7-segment display units are changed every 0.5 seconds. same It is allowed to control the CPU110 is blinked by. Therefore, the operator can easily determine which lane is in the full notice state.

  Therefore, the operator can understand that the amount of the cover tape collected in the cover tape collecting and storing unit 26 is in a full notice state. Therefore, the operator opens the door 73 and takes out the cover tape from the collecting and storing unit 26. It is possible to perform an operation of cutting the cover tape and reducing the collected storage amount. Therefore, if the control of stopping the operation of the device is suddenly performed because the battery is suddenly full, the operation rate of the electronic component mounting operation is deteriorated. However, according to the present embodiment, the operation rate is deteriorated. Can be avoided. Note that, after the operator performs an operation to reduce the collected storage amount, the display of the liquid crystal display unit 70A is reset and the blinking stops by pressing a reset button (not shown) of the component supply unit 6. .

  However, if the full notice state is not canceled and the operation for reducing the collected storage amount is not performed, the full state will eventually be reached. In this case, the time measured for the recovery drive motor 42 exceeds the time-out determination time longer than the full notice determination time, so the time measured by the monitoring timer 121 for the operation time of the recovery drive motor 42 is exceeded. When it is determined whether or not a timeout determination time (abnormal stop) longer than the full notice determination time has been exceeded, the operation of the recovery drive motor 42 is turned off (stopped), the monitoring timer 121 is reset, and the timer is full. In order to register the abnormality, the CPU 110 stores in the RAM 111 that the component supply unit 6 is in a full state due to the cover tape being full.

  Therefore, after this full abnormality registration, it is determined whether or not the tape feed servo motor 25 is in operation and not in operation. Next, it is determined whether or not the recovery drive motor 42 is in operation. Instead, when the CPU 110 determines whether there is an abnormality registration, if it is determined that there is an abnormality registration, the CPU 11 performs an abnormality notification process.

  That is, information indicating that there is an abnormality is displayed on the monitor 119 to notify that the amount of the cover tape collected in the cover tape collection and storage section 26 of the component supply unit 6 is full and an abnormal state has occurred. The notification is not limited as long as it is a notification means that can notify the worker visually or audibly. When full, notification of full notice is stopped and a 7-segment display unit may be used to display, for example, “E0.” For the right lane and “E.0” for the left lane. .

  Further, the CPU 11 controls the electronic component mounting apparatus to be abnormal and stop the operation of the apparatus, that is, stop the component adsorption and the component mounting operation on the printed circuit board. Further, instead of stopping the operation of the apparatus, the parts feeding of the target part supply unit 6 and the recovery of the cover tape may be stopped, that is, the parts supply operation of the target part supply unit 6 may be stopped. In this case, if there is a component supply unit 6 that can supply the same component, the component supply unit 6 may supply (alternate) the component and continue the operation of the electronic component mounting apparatus, provided that When the alternate cannot be performed, the operation of the electronic component mounting apparatus is stopped. Further, since the parts cannot be taken out from the full supply part 6 without being alternated, the full supply part 6 passes, and the next part is supplied with a non-full part. It may be supplied from the unit 6 and mounted, and then the components may be supplied from the component supply unit 6 that is in a full state where the cover tape is cut and mounted, and the printed circuit board may be finished (recovered later).

  In any case, as described above, the display of the liquid crystal display unit 70A is reset when the operator presses the reset button (not shown) of the component supply unit 6 after the cover tape is full. Then, the notification that it is full and becomes abnormal is stopped.

  In addition, since the feed pitch and the length at the time of collection differ depending on the type of the storage tape C, the above-described full notice determination time and timeout determination time (full determination time) may be changed for each type of storage tape.

  Since the detection device for controlling the recovery of the cover tape recovery device is used for full notification and full notification, the component supply unit 6 can be made compact and the mechanism can be simplified.

  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 embodiments described above without departing from the spirit of the present invention. It encompasses alternatives, modifications or variations.
