Description

  In the present invention, a plurality of component supply units that supply electronic components in a storage tape to a component extraction position by a feed drive source are arranged in parallel on a feeder base of the apparatus main body, and the electronic components taken out from the component supply units are placed on a printed circuit board. The present invention relates to an electronic component mounting apparatus to be mounted on a machine.

In this type of electronic component mounting device, particularly a high-speed gantry-type mounting device, the component supply unit is fixed and does not move. Therefore, so-called splicing replenishment in which storage tapes are connected and replenished during automatic operation is employed. The number of users is increasing rapidly. The splicing replenishment timing manages the remaining number of electronic components, notifies the operator when the predetermined remaining number is reached, and the worker performs the splicing replenishment for the target component supply unit. And this kind of connection method of storage tape is disclosed by patent document 1, etc., for example.

  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, 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). A plurality of component supply units 6 that are electronic component supply devices are detachably incorporated in each 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.

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 11 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 provided with a storage tape C (described later) in which a large number of electronic components are stored in each storage portion Cb at regular intervals. By intermittently feeding the storage tape C, the component supply unit 6 One electronic component is supplied from the tip to the component mounting portion 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 motor 12Y of the XY stage 12 and the θ-axis motor 18A of the suction nozzle 18 are corrected and moved down by the vertical axis motor 18B to mount the electronic component on the printed circuit board P.

  The component supply unit 6 that is a dual lane feeder will be described below with reference to FIGS. The component supply unit 6 attached to the cart detachable from the electronic component mounting apparatus main body 1 is configured so that electronic components can be separately and independently supplied from the two storage tapes C by two drive sources. This component supply unit 6 includes a unit frame 21, two supply reels (not shown) that are rotatably mounted on a cart, and a storage tape C that is sequentially wound in a state of being wound around each supply reel. From two tape feeding mechanisms (tape feeding devices) 22 that intermittently feed to the (suction take-out position), and two later-described cover tape peeling mechanisms 23 for peeling the cover tape Ca from the carrier tape Cc before the pickup position. Composed.

  The storage tape C fed out from the storage tape reel is fed to the pickup position so as to dive under the suppressor 24 disposed in the tape path before the pickup position. The suppressor 24 has an opening 25 for pickup. A slit 26 is formed in the suppressor 24, and the cover tape Ca of the storage tape C is peeled off from the carrier tape Cc from the slit 26 and stored in the storage portion 27. That is, the electronic component housed and mounted on the carrier tape Cc is sent to the pickup opening 25 with the cover tape Ca peeled off, and is picked up by the suction nozzle 18.

  Next, the tape feeding mechanism 22 will be described with particular reference to FIGS. Each tape feeding mechanism 22 includes a servo motor 31 having a gear 30 on its output shaft and a reversible servo motor 31 and a gear 33 having a timing belt 32 stretched between the gear 30 at one end. 34 is provided with a rotation shaft 36 rotatably supported by a bearing 35 and a worm wheel 38 meshing with a worm gear 37 provided at an intermediate portion of the rotation shaft 36, and in a feed hole Cd formed in the carrier tape Cc. The sprocket 39 is configured to mesh and send the same. The worm wheel 38 and the support shaft 40 of each sprocket 39 pass through the intermediate partition of the unit frame 21.

  Accordingly, when one of the servo motors 31 is driven to rotate in order to supply the electronic components in the one storage tape C in the component supply unit 6, the gear 30 and the gear 33 are rotated via the timing belt 32. Only the rotary shaft 36 rotates, and the sprocket 39 rotates intermittently by a predetermined angle in the feed direction via the worm gear 37 and the worm wheel 38, whereby one storage tape C is intermittently fed through the feed hole Cd.

  Next, the cover tape peeling mechanism 23 will be described with reference to FIGS. Each cover tape peeling mechanism 23 rotatably supports a drive motor 42 provided with a worm gear 41 on its output shaft and a gear 45 and a gear 43 meshing with the worm gear 41 via a support shaft 46 to rotate the unit frame 21. The support body 44 fixed to the unit frame 21 and the support body 49 fixed to the unit frame 21 via the attachment body 48 by rotatably supporting the gear roller 47 engaged with the rubber roller 51 and the gear 45 via the support shaft 50. An oscillating body 54 that is supported by a spring 55 so as to be able to rotate through a support shaft 56 and can swing through a support shaft 53, and a cover. The roller 57 for guiding the tape Ca and the cover tape guided by the roller 57 to the end of the attachment body 59 that can swing on the unit frame 2 via the support shaft 58. It consists biased to swing in the clockwise direction in FIG. 1 by a spring 61 Metropolitan tension applying member 62 for applying tension to the cover tape Ca provided with a roller 60 for guiding the Ca. Reference numeral 63 denotes a stopper for restricting the swing of the mounting body 59.

  Therefore, when the cover tape Ca is peeled off, when the drive motor 42 is driven, the gears 43 and 45 are rotated via the worm gear 41, and when the gear 45 is rotated, the gear 47 and the rubber roller portion 51 are rotated. Therefore, the rubber roller portion 52 rotates while the rubber roller portion 51 and the rubber roller portion 52 sandwich the cover tape Ca, and the cover tape Ca is peeled off from the carrier tape Cc by one pitch from the slit 26 of the suppressor 24. Then, it is housed in the housing portion 27 provided at the end of the component supply unit 6 without causing slack.

  Further, as shown in FIGS. 5 and 6, the suppressor 24 includes a vertical piece 24A serving as a support portion and a horizontal piece 24B for holding the storage tape C engaged with the teeth of the sprocket 39 so that the feed hole Cb is engaged with the horizontal piece 24B. The section is generally L-shaped, and a vertical piece 24A is supported on the unit frame 21 so as to be rotatable about a support shaft 24C at the rear end portion, and is locked to the front end portion of the horizontal piece 24B. A vertical locking piece 24D having a locking hole 24E that can be locked to a locking body (not shown) biased by a spring in the direction is provided.

  The suppressor 24 that serves as a peeling fulcrum of the cover tape Ca is communicated with the tape passage formed in the unit frame 21 from the side of the component supply unit 6 in a state where the suppressor 24 is rotated upward with the support shaft 24C as a fulcrum. The storage tape C is configured to be loaded into the component supply unit 6 through the loading opening 65. Reference numeral 66 denotes a prevention member for preventing the storage tape C loaded in the component supply unit 6 from being detached from the loading opening 65, and is provided in the vicinity of the rear end portion of the horizontal passage in the tape passage, in the middle portion, or in the oblique passage. It is provided in the vicinity of the upper end or at the boundary between the horizontal passage and the oblique passage (see FIG. 2).

  Reference numeral 67 denotes a power supply line for supplying power to the servo motor 31, the drive motor 42 and the like.

  Next, the feeding operation of the storage tape C and the peeling operation of the cover tape Ca will be described. A control device (not shown) of the electronic component mounting apparatus main body 1 responds according to mounting data (data on which electronic component is mounted in which position on which direction on the printed circuit board) stored in a RAM 81 to be described later. The tape feeding mechanism 22 of the predetermined component supply unit to be driven is driven, and the storage tape C that stores the predetermined electronic component in the storage portion Cb is intermittently fed once. That is, when one servo motor 31 is driven to rotate forward, the gear 30 and the gear 33 are rotated to rotate the rotating shaft 36, and the sprocket 319 is intermittently moved in the feed direction by a predetermined angle via the worm gear 37 and the worm wheel 38. By rotating, one storage tape C is intermittently fed through the feed hole Cd. At this time, since the other rotating shaft 36 does not rotate, the other storage tape C is not intermittently fed.

  When this tape feed mechanism 22 is driven, one corresponding cover tape peeling mechanism 23 peels (peels) one intermittent feed of the cover tape Ca in synchronism with this. Subsequently, when the tape feeding mechanism 22 and the cover tape peeling mechanism 23 are stopped, the electronic component is fed to the pickup position. Then, 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 component sucked and held by the suction nozzle 18 of the electronic component mounting apparatus is mounted on the printed circuit board P.

  Next, the remaining electronic components in the storage tape C are reduced, and the storage tape C (for convenience of explanation, “old storage” is used without removing the component supply unit 6 from the feeder base 19 during operation of the electronic component mounting apparatus. The operation (splicing replenishment) when the new storage tape C is connected to the tape “C” and loaded into the component supply unit 6 will be described.

  First, near the end of the old storage tape C extending from the unit frame 21, the carrier tape Cc and the cover are located at the intermediate position between the feed hole Cd and the feed hole Cd and at the center position in the feed direction of the storage portion Cb. Cut the tape Ca so that it is at the same surface position, and remove this old supply reel that is rotatably mounted on the cart.

  Next, separately from this, at the starting end of a new storage tape C wound on a new supply reel placed on the cart, like the old storage tape C, an intermediate position between the feed hole Cd and the feed hole Cd. Then, the cover tape Ca is cut longer than the carrier tape Cc at the center position in the feeding direction of the storage portion Cb.

  Then, the new storage tape C and the old storage tape C are made to coincide with the cut end face of the carrier tape Cc so that the cover tape Ca of the new storage tape C is covered on the cover tape Ca of the old storage tape C. (See FIGS. 7 and 8). In the storage portion Cb formed so as to match, the carrier tape Cc is connected to each other with an adhesive connecting tape 68A so that both surfaces are sandwiched, and the cover tape Ca is connected to the connecting tape 68B. , 68C.

  Reference numeral 69 denotes a joint detection device for the storage tape C, which is provided at the rear end of the component supply unit 6. The seam detection device 69 includes a device main body in which a light emitting element and a light receiving element are provided at a distance of 8 millimeters, a prism at the upper end, a U-shaped cross section, and an intermediate portion accommodated. It is comprised from the channel | path formation body in which the opening part for tape channel | paths was provided so that the tape C might pass.

  In other words, in the case of the storage tape C having no seam along with the feeding operation of the storage tape C, the light from the light emitting element is retro-reflected by the prism through the feed holes (opened at intervals of 4 millimeters) Cb to receive the light. Since the light is received by B, the seam detection device 69 can detect the absence of a seam. In the storage tape C having a seam, the light from the light emitting element is shielded by the connecting tape 68A covering the feed hole Cb in accordance with the feeding operation. No light is received by the light receiving element, and the presence of a joint is detected.

  Next, a control block diagram of the electronic component mounting apparatus main body 1 and the component supply unit 6 of FIG. 9 will be described. Reference numeral 80 denotes a CPU (Central Processing Unit) as a control device that performs overall control of operations related to taking out and mounting of the electronic components of the electronic component mounting apparatus, 81 is a RAM (Random Access Memory) as a storage device, and 82 is ROM (Read Only Memory). Then, based on the data stored in the RAM 81, the CPU 80 operates in accordance with the program stored in the ROM 82 with respect to operations related to taking out and mounting the electronic component of the electronic component mounting apparatus via the interface 83 and the drive circuit 84. Etc.

  In the RAM 81, the X direction, Y direction, and angle information in the printed circuit board P for each mounting order (for each step number), and the component supply unit 6 arranged in parallel on the feeder base 19 of each component supply unit 6. , Ie, mounting data (for each printed circuit board type) such as arrangement number information is stored, and each electronic component type (component ID) corresponding to the arrangement number (lane number) of each component supply unit 6 is stored. Information, that is, component arrangement information. In addition, component library data composed of items representing the characteristics of electronic components for each component ID is also stored.

  Further, when performing splicing for connecting the storage tapes C to each other, an operator can set a serial number consisting of a barcode written on a label attached to a supply reel of the storage tape C loaded in the component supply unit 6. When read with a code reader (not shown), a predetermined number is traced back from the latest serial number read for each arrangement number (lane number) of the component supply unit 6 arranged side by side on the feeder base 19 For example, five serial numbers are stored (see FIG. 10).

  The storage of the last five serial numbers is performed for each arrangement number of the component supply unit 6. However, the present invention is not limited to this, and may be performed for each component supply unit 6 including the supply reel. These pieces of information are also stored in a server 96 provided outside the electronic component mounting apparatus main body 1 and the component supply unit 6.

  A recognition processing device 85 is connected to the CPU 80 via an interface 83, and recognizes an image captured and captured by the component recognition camera 14 and an image captured and captured by the board recognition camera 17. Recognition processing is performed by the recognition processing device 85, and the processing result is sent to the CPU 80. That is, the CPU 80 outputs an instruction to the recognition processing device 85 to perform recognition processing (calculation of misalignment amount, etc.) on the image captured by the component recognition camera 14 or recognition processing of the image captured by the board recognition camera 17. In addition, the recognition processing result is received from the recognition processing device 85.

  That is, when the amount of positional deviation is grasped by the recognition processing of the recognition processing device 85, the result is sent to the CPU 80, and based on the result of the component recognition processing and the board recognition processing, the CPU 80 performs the X-axis motor 12X and the Y-axis motor 12Y. The suction nozzle 18 is moved in the X and Y directions by this driving, and is rotated by θ by the θ axis motor 18A, and the rotational angular position about the X and Y directions and the vertical axis is corrected.

  The monitor 86 as a display device is provided with various touch panel switches 87 as input means for data setting. The operator can perform various settings by operating the touch panel switch 87. The setting data is stored in the RAM 81. Stored in Reference numeral 88 denotes a counter which subtracts “1” for each feeding of the storage tape C from the set number of stored electronic components or adds for every feeding. When the remaining number reaches the predetermined number stored based on the count value of the counter 88. The CPU 80 connects the old storage tape C and the new storage tape C and turns on the illumination lamp or the like by the notification means 89 and sounds the buzzer or the like by assuming that the splicing supply timing for supplying the electronic parts has come.

  It is also possible to manage the length of the storage tape C instead of the number of electronic components stored as described above, and to notify the notification means 89 when the length of the remaining storage tape C reaches a certain length. Good.

  90 is a CPU mounted on a printed circuit board (not shown) built in the component supply unit 6, 91 is a RAM, 92 is a ROM, and 93 and 93 are connected to the CPU 90 via an interface 94. 2 is a drive circuit of each servo motor 31 of the tape feeding mechanism 22 and a drive motor 42 of the cover tape peeling mechanism 23;

  Next, the feeding operation of the storage tape C will be described. First, according to the mounting data stored in the RAM 81, the CPU 80 of the electronic component mounting apparatus main body 1 confirms that the feeder preparation completion signal is ON from the corresponding component supply unit 6, and the feeder supply command signal from the CPU 80 corresponds to the corresponding component supply unit. 6 to CPU 90.

  Then, the CPU 90 turns off the feeder preparation completion signal of the component supply unit 6 and sends it to the CPU 80, and also drives the tape feeding mechanism 22 of the component supply unit 6 to intermittently feed the storage tape C for storing predetermined electronic components once. Let That is, when the servomotor 31 is driven to rotate forward, the gear 30 and the gear 33 rotate to rotate the rotating shaft 36, and the sprocket 39 rotates intermittently by a predetermined angle in the feed direction via the worm gear 37 and the worm wheel 38. Thus, the storage tape C is intermittently fed through the feed hole Cd. When the tape feeding mechanism 22 is driven, the cover tape peeling mechanism 23 peels the cover tape Ca for one intermittent feed in synchronization with this, and then the tape feeding mechanism 22 and the cover tape peeling mechanism 23 are stopped. Then, the electronic component is sent to the pickup position.

  Then, when the feeding operation by the tape feeding mechanism 22 is completed, the feeder preparation completion signal turned off during the operation is turned on, and the CPU 90 outputs a feeder preparation completion signal on to the CPU 80. Receiving this, the CPU 80 determines that the storage tape feeding operation has been completed, and drives the X-axis motor 12X and the Y-axis motor 12Y to move the electronic component to be extracted to the component extraction position 6 above the component extraction position. The suction nozzle 18 that has been moved is lowered by driving the vertical axis drive motor 18B to pick up electronic components and are mounted on the printed circuit board P. However, the suction operation is completed (the suction nozzle 18 is lifted). At the time of completion, the CPU 80 again sends a feeder feed command signal to the CPU 90 of the corresponding component supply unit 6.

  The above operations, that is, the electronic component feeding operation, taking-out operation, and mounting operation are repeated, and the printed circuit board P is produced. Then, electronic components are sequentially taken out from the storage tape C by the suction nozzle 18 and mounted on the printed circuit board P. The number of electronic components in the storage tape C of the component supply unit 6 decreases, and is subtracted every time the electronic components are taken out. When the count value by the counter 88 reaches a predetermined value, the splicing replenishment timing is reached, and the CPU 80 notifies the fact by the notification means 89.

  For this reason, the operator can perform the operation of connecting the new storage tape C to the old storage tape C and loading it into the component supply unit 6. That is, near the end of the old storage tape C extending from the unit frame 21, the carrier tape Cc and the cover tape are located at the intermediate position between the feed hole Cd and the feed hole Cd and at the central position in the feed direction of the storage portion Cb. Cut the old supply reel from the cart while cutting so that Ca is in the same plane position.

  Next, before attaching to the unit frame 21, the serial number and the electronic component type (component ID) consisting of the barcode written on the label attached to the supply reel of the new storage tape C connected to the old storage tape are set. The operator reads it using a bar code reader (not shown). When read in this manner, a predetermined number, for example, five serial numbers, is stored retroactively from the latest serial number for each arrangement number of the component supply unit 6 stored in the RAM 81 and the server 96 and arranged in parallel on the feeder base 19. Are sequentially stored.

  And, at the starting end of the new storage tape C wound on the new supply reel placed on the cart, at the intermediate position between the feed hole Cd and the feed hole Cd and in the central position in the feed direction of the storage part Cb, Cut the cover tape Ca longer than the carrier tape Cc. Then, the cut end surfaces of the carrier tapes Cc of the old and new storage tapes C are matched, and the cover tape Ca of the new storage tape C is superposed on the cover tape Ca of the old storage tape C, and the connecting tape 68A, It connects by 68B and 68C (refer FIG.7 and FIG.8).

  As shown in FIG. 11, when the splicing replenishment operation is performed as described above, the operator presses the touch panel switch 87 displayed on the monitor 86 to perform the splicing replenishment operation. When the part arrangement number is specified and the bar code written on the label attached to the new supply reel is read using the bar code reader, the CPU 80 first checks whether the electronic part type (part ID) matches. If they do not match, the monitor 86 is abnormally displayed. If they match, the CPU 80 compares the read contents with the latest five serial numbers stored for each arrangement number of the component supply unit 6 arranged side by side on the feeder base 19.

  That is, the CPU 80 designates the latest serial number among the five serial numbers stored at the beginning, and determines whether or not it is the same as the serial number read this time. Display an error. Also, if it is determined that they are not the same, if it is not the last (fifth) serial number, the next serial number is designated, and similarly, it is determined whether it is the same as the serial number read this time. If it is determined that they are the same, an abnormality is displayed on the monitor 86, and if they are not all the same, they are stored in the RAM 81 and the server 96 as the latest serial numbers.

  In this manner, for example, five serial numbers are sequentially stored retroactively from the latest serial number for each arrangement number of the component supply units 6 arranged side by side on the feeder base 19.

  Thus, during operation of the electronic component mounting apparatus, the splicing replenishment operation is performed without removing the component supply unit 6 from the feeder base 19, but the electronic components are sequentially taken out and mounted on the printed circuit board P. It will be. And when there is a serial number that is the same as the serial number read this time (when the barcode of an old supply reel that is not a new supply reel is read), or when the electronic component type (component ID) does not match, An error is displayed on the monitor 86. However, in the former case, “serial number duplication error” is displayed, and in the latter case, “part ID mismatch” is displayed.

  Therefore, when the operator looks at the screen, the splicing replenishment operation of the component supply unit 6 relating to the abnormally displayed arrangement number on the monitor 86 has been mistakenly performed, or the supply reel check operation has not been performed reliably. Since the operator can know, the connection between the new storage tape C and the old storage tape C is released, and a new splicing replenishment operation for connecting the appropriate storage tape C is performed. The displayed touch panel switch 87 is pressed to designate the component arrangement number of the component supply unit 6 that will perform the splicing replenishment operation, and the barcode reading operation of the new supply reel barcode reader as described above is performed. Do.

  If it is determined that a new splicing replenishment operation for connecting the proper storage tape C is performed by performing this reading operation, there is no problem, but if the replacement reel is not replaced with a proper storage tape supply reel, a sequential mounting operation is performed. Before the seam detecting device 69 detects the joint where the connecting tape 68A has covered the feed hole Cb of the storage tape C of the component supply unit 6 relating to the arrangement number, the CPU 80 processes as follows.

  That is, the number of feeds from the joint detection device 69 until the electronic component reaches the suction extraction position is required N times, and before the component storage portion of the newly added storage tape C reaches the joint detection device 69, that is, it is old. When a counter (not shown) counts that the number of remaining parts of the storage tape has decreased to a number corresponding to the number of feeds slightly greater than N times, the CPU 80 performs the electronic component mounting operation by the electronic component mounting apparatus. Control to stop. Therefore, when the operation is stopped, an old storage tape having a length that can be used by the operator described below remains.

  Therefore, since the operation of the electronic component mounting apparatus has been stopped, the operator will further know that the splicing replenishment operation of the component supply unit 6 related to the arrangement number displayed abnormally on the monitor 86 has been erroneously performed. It is necessary to disconnect the new storage tape C and the old storage tape C that are connected in this manner, and connect the appropriate storage tape C.

  As described above, the abnormal display is performed, and then the proper splicing replenishment operation is not performed, and control is performed to stop the operation of the electronic component mounting apparatus when the joint is detected. You may control to stop driving | operation.

  Note that a predetermined number of serial numbers are traced back from the latest serial number read by the barcode reader for each component supply unit 6 or for each arrangement number of the component supply unit 6 arranged in parallel on the feeder base 19. Although it is stored in the server 96, the number is not limited to such a predetermined number, but may be a number stored within a predetermined capacity range allocated to the RAM 81 and the server 96.

  The electronic component mounting apparatus has been described by taking a so-called multi-function chip mounter as an example. However, the present invention is not limited to this and may be applied to a high-speed chip mounter such as a rotary table type.
