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 is used in which storage tapes are connected and replenished during automatic operation. Users are 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 tapes is disclosed by patent documents 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, 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. 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 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 is configured so that electronic components can be separately and independently supplied from the two storage tapes C by two drive sources. The component supply unit 6 is an electronic unit that receives a unit frame 21, two storage tape reels (not shown) rotatably mounted on the unit frame 21, and a storage tape C that is sequentially drawn out while being wound around each storage tape reel. Two tape feeding mechanisms (tape feeding devices) 22 that intermittently feed the parts to the pick-up position (suction take-out position), and two later-described cover tape peeling methods for peeling the cover tape Ca from the carrier tape Cc before the pick-up position And a mechanism 23.

  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 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. 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 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. It cut | disconnects so that the tape Ca may become the same surface position.

  Next, separately from this, at the starting end portion of the new storage tape C wound around the storage tape reel, similarly to the old storage tape C, it is an intermediate position between the feed hole Cd and the feed hole Cd and the storage portion Cb. The cover tape Ca is cut longer than the carrier tape Cc at the center position in the feed direction.

  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.

  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 according to 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.

  The RAM 81 is mounted 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). Data is stored, and information on the type (component ID) of each electronic component corresponding to the arrangement number (lane number) of each component supply unit 6, that is, component arrangement information is stored. Furthermore, component library data composed of items representing the characteristics of the electronic component for each component ID is also stored.

  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 causes the monitor 86 to slowly display a mode setting / cancellation operation screen on the assumption that the splicing replenishment timing for replenishing electronic components by connecting the old storage tape C and the new storage tape C is reached. Reference numeral 89 denotes a management timer, which starts timing when the mode is switched slowly, and controls the CPU 80 to switch from the slow mode to the normal mode when the predetermined time has elapsed.

  This normal mode is a mode in which the cycle time for feeding electronic components in the component supply unit 6 and taking out by the suction nozzle 18 is a normal length, and the slow mode is a mode in which the cycle time is longer than the normal mode. It is.

  The length of the storage tape C is managed instead of the number of electronic components stored as described above, and when the remaining storage tape C reaches a certain length, the mode setting / release operation screen is slowly displayed on the monitor 86. You may make it display.

  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 based on the timing shown in FIG. First, according to the mounting data stored in the RAM 81, the CPU 80 of the electronic component mounting apparatus 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 is completed, drives the vertical axis drive motor 18B to lower the suction nozzle 18, and picks up the electronic components to be mounted on the printed circuit board P. However, when the suction operation is completed (up of the suction nozzle 18 is completed), 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, as shown in FIG. 11, the electronic components are sequentially taken out from the storage tape C by the suction nozzle 18 and mounted on the printed circuit board P, and the electronic components in the storage tape C of the component supply unit 6 are reduced. When the count value by the counter 88 reaches a predetermined value after subtraction every time an electronic component is taken out, the splicing replenishment timing is reached, and the CPU 80 informs that by a notifying device (not shown) that visually or audibly notifies. At the same time, the “slow mode” setting / cancellation operation screen (see FIG. 12) is displayed on the monitor 86.

  Accordingly, in FIG. 12, when the operator slowly presses the mode switch portion 87A, the display color of the slow mode switch portion 87A becomes blue. Data is stored in the RAM 81.

  For this reason, as described above, a feeder feed command signal is sent from the CPU 80 to the CPU 90 of the corresponding component supply unit 6, and the CPU 90 sends the feeder preparation completion signal of this component supply unit 6 to the CPU 80 and turns it off. 6, when the tape feeding mechanism 22 is driven to intermittently feed the storage tape C storing a predetermined electronic component once, this slow mode is set, so the CPU 80 feeds the tape through the CPU 90 and the drive circuit 93. Control is performed so that the feeding operation by the servo motor 31 of the mechanism 22 is decelerated as compared with the normal mode.

  That is, as shown in FIG. 13, as described above, the feeder feed command signal is sent from the CPU 80 to the CPU 90 of the corresponding component supply unit 6, and the CPU 90 turns off the feeder preparation completion signal of the component supply unit 6. In addition, the storage tape C is intermittently fed once while the feeding operation by the servo motor 31 of the tape feeding mechanism 22 of the component supply unit 6 is decelerated.

  For this reason, the operator can calmly 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 without panicking. 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 so that Ca has the same surface position. Next, at the starting end portion of the new storage tape C wound around the storage tape reel, the cover tape Cc is covered by the carrier tape Cc 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. The tape Ca is lengthened and cut. 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 with 68B and 68C.

  As shown in FIG. 14, when an operation for switching from the normal mode to the slow mode is instructed and the mode is switched to the slow mode, the CPU 80 sets a management timer 89 to start timing and performs a mode extension operation instruction slowly. It is determined whether or not it has been done. If no instructions are given, return to the original.

  If the management timer 89 does not measure the lapse of time-up time, the mode is maintained slowly, but before the time-up time elapses, the mode switch unit 87A and the setting switch unit 87B as shown in FIG. 12 are pressed. When the slow mode extension switch 87C displayed on the monitor 86 shown in FIG. 15 is pressed, the slow mode management timer 89 is reset and reset, so that the slow mode is extended. The CPU 80 controls as described above.

  Then, when the management timer 89 measures the elapsed time, the CPU 80 slowly switches from the normal mode to the normal mode, and performs control at the timing of the electronic component feeding operation shown in FIG.

  As described above, the servo motor 31 of the tape feeding mechanism 22 is decelerated to delay the feeding speed of the storage tape C. However, the present invention is not limited to this, and the storage is performed using a timer as shown in FIG. After completion of the feeding operation of the tape C, the lowering of the suction nozzle 18 is not started immediately, but the lowering start time of the suction nozzle 18 is delayed without changing the suction operation time. In addition, the cycle time related to the suction and picking-out operation by the suction nozzle 18 and the mounting time (cycle time) per one electronic component are lengthened so that the operator can connect the old storage tape C and the new storage tape C. You may be able to calm down.

  Further, when the suction nozzle 18 descends for taking out the electronic component, the timing of starting the suction nozzle 18 is delayed by delaying the suction nozzle 18 by using a timer at its lowest limit level, In the case where the plurality of suction nozzles 18 are provided, the next suction nozzle indexing operation time for chain suction, in which electronic parts are sucked and held by more suction nozzles 18, or the ascending / descending speed of the suction nozzles 18 is increased. The cycle time related to the electronic component feeding operation and the suction taking-out operation by the suction nozzle 18, and thus the mounting time (cycle time) per electronic component may be extended.

  In the above embodiment, when the splicing replenishment timing is reached, the switching mode from the normal mode to the slow mode is set slowly. It may be possible to perform the switching setting to the mode slowly when the component supply unit 6 of this time comes. Therefore, if a single component supply unit comes at the splicing replenishment timing, or even if the splicing replenishment timing overlaps with multiple component supply units, the operator should not be overwhelmed when performing the splicing replenishment operation. Appropriate splicing replenishment work can be performed, and productivity can be improved. Moreover, even if it is not the timing of replenishment of splicing, it may be possible to perform switching setting at any time, or it may be possible to perform switching setting before starting the operation of the electronic component mounting apparatus.

  Also, when it comes to splicing replenishment timing, priority is given to parts supply and mounting from other parts supply units that store the same or different types of electronic parts, and during that time splicing replenishment work can be done without hesitation. Also good.

  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.

  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.
