Abstract

<P>PROBLEM TO BE SOLVED: To provide a component supply device capable of giving facilities for subsequent processing by a worker by letting the worker know that a cover tape storage unit is full of a peeled cover tape. <P>SOLUTION: When electronic components are repeatedly taken out of a component supply unit 6 and the amount of the cover tape peeled and stored in a storage space S of the cover tape storage unit 26 increases until the storage space S becomes full, a force opening an opening/closing door 50 exceeds the magnetic force of a magnet 58. Then a boundary part between an inclined plane 51A and an arcuate part 51B contacts and engages a lower part of a winding base 60A of a winding unit 60 in a state wherein the arcuate part 51B is in contact with an opposed plane part 60C, so that the opening/closing door 50 is held slightly open. Therefore, the worker understands the fullness and further opens the opening/closing door 50 so as to take the cover tape out of the storage space S and cut the cover tape while leaving it by a necessary amount, so that while the winding base 60A and opposed plane part 60C are in contact with the arcuate part 51B, the opening/closing door 50 is opened to be fully open. <P>COPYRIGHT: (C)2009,JPO&INPIT

  The present invention can provide a component supply device that can facilitate the subsequent processing by the operator by notifying the operator that the cover tape peeled in the cover tape storage portion is full.

  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 multifunctional chip mounter that is a so-called high-speed gantry mounting apparatus, 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 center set table 8, a supply conveyor 9 on the left side, and a discharge conveyor 10 on the right side. 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, and the head unit 13 is moved in the X direction by the X-axis drive motor. As a result, the head unit 13 is moved 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 equipped with a storage tape in which a large number of electronic components are stored in the respective component storage portions of the carrier tape at regular intervals. By intermittently feeding the storage tape, the front end of the component supply unit 6 is mounted. The electronic components are supplied to the component mounting unit 4 one by one.

  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 is picked up (taken out) from the carrier tape from which the cover tape has been peeled off. 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, the Y-axis motor of the XY stage 12 and the θ-axis motor of the suction nozzle 18 are corrected and moved to mount the electronic component on the printed circuit board P.

  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 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 a position) and a cover tape peeling mechanism (not shown) for peeling the cover tape of the storage tape before the pickup position.

  The storage tape fed out from the storage tape supply reel is fed to the pickup position so as to dive under the suppressor 23 disposed in the tape path before the pickup position. The suppressor 23 has an opening for pickup. The suppressor 23 is formed with a slit, and the cover tape of the storage tape is peeled from the carrier tape through the slit and stored in the cover tape storage portion 26 having the storage space S. That is, in a state where the cover tape is peeled off by the cover tape peeling mechanism, the electronic component mounted on the component storage part of the carrier tape is sent to the pickup opening by the feeding mechanism 22 and is picked up by the suction nozzle 18. Become.

  Next, the tape feeding mechanism 22 will be described. The tape feeding mechanism 22 is a second motor in which a timing belt is stretched between the first gear and a servo motor (not shown), which is a drive source capable of forward and reverse rotation, provided with a first gear on its output shaft. A rotating shaft (not shown) provided with a gear at one end and rotatably supported by a support via a bearing, and a worm wheel meshing with a worm gear provided at an intermediate portion of the rotating shaft and a storage tape And a sprocket 27 which meshes with and feeds the feed hole formed in the above. The worm wheel 28 and the support shaft 29 of the sprocket 27 pass through the intermediate partition body of the unit frame 21.

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

  Further, the suppressor 23 has a substantially U-shaped cross section from both vertical pieces serving as support parts and a horizontal piece that holds the storage tape meshed with the teeth of the sprocket 27 so as not to come off. When the locking is released and the locking 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 is urged downward to press the storage tape in which the feed hole of the storage tape is engaged with the feed dog of the sprocket 27 so as not to come off.

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

  Then, when the component supply unit 6 is attached to the feeder base 19, the guided member 41 is guided by a pair of guide members provided on the feeder base 19 by the operator holding the handle 40. While moving in the depth direction, the roller 42 is locked to a locking member provided in the electronic component mounting apparatus main body 1. When the guided member 41 is guided by the pair of guide members and the guided member 41 is slid (slid) on the feeder base 19 and moved to attach the component supply unit 6, the feeder A front-rear restricting member (not shown) that restricts the position of the component supply unit 6 in the front-rear direction by contacting the guided member 41 is provided at the end of the base 19 on the depth side.

  The suppressor 23 acts so that the carrier tape feed hole of the sprocket 27 does not come off from the tape feed teeth of the sprocket 27 by constantly pressing the carrier tape after peeling the storage tape and cover tape against the tape guide chute.

  Then, the lower end of the open / close door 50 that closes the external opening 52 (opening from the outside of the printed circuit board P) that forms the storage space S of the cover tape storage portion 26 can be rotated with the support shaft 51 wound around it. It is supported. That is, the support shaft 51 extends between the opposing side walls 54 that form the external opening 52 that opens obliquely so as to be outward as it goes downward, and at a lower position of the side walls 54. The opening / closing door 50, which is a magnetic body, is disposed so as not to rotate, and is supported rotatably so that the lower end of the door 50 is wound around the support shaft 51, and the upper portion can be opened and closed with the lower portion serving as a fulcrum.

  A magnet 58 is embedded in a rear surface 57 of the upper wall 56 that forms the external opening 52. When the opening / closing door 50 is attracted by the magnetic force of the magnet 58, the external opening 52 is closed.

  The support shaft 51 has a circular cross section, ie, a cross-section in a direction perpendicular to the longitudinal direction, which is formed by an arc and a chord as shown in FIG. An inclined surface 51A that is cut in an oblique direction so as to approach the (storage space S direction) and an arc portion 51B having a central angle of about 290 degrees are formed. As shown in FIGS. 2 and 3A, the open / close door 50 in a state of being attracted by the magnetic force of the magnet 58 closes the external opening 52 in an inclined state so that the upper part is located inward. ing.

  A winding portion 60 of the opening / closing door 50 that is wound around the support shaft 51 so as to be rotatable is a flat winding base portion 60A and an arc portion of the support shaft 51 that is continuous with the winding base portion 60A. The first arc portion 60B having a large diameter but concentric circles, the opposing flat surface portion 60C that is continuous to the first circular arc portion 60B and parallel to the winding base portion 60A, and the opposing flat surface portion 60C are connected to the first flat portion 60C. It comprises a first arc portion 60B and a second arc portion 60D having the same radius. And the space | interval of the said winding base part 60A and the opposing plane part 60C is the intersection of the vertical line which passes along the center of the inclined surface 51A of the said spindle 51, and the string which forms this inclined surface 51A, and the circular arc part 51B. It is formed slightly longer than the length.

  Due to the above configuration, in the component supply unit 6, the storage tape fed from the storage tape supply reel is fed under the suppressor 23 disposed in the tape path in front of the pickup position and is sent to the slit of the suppressor 23. The cover tape is peeled off from the carrier tape by the cover tape peeling mechanism through the cover and stored in the cover tape storage portion 26 having the storage space S. That is, in a state where the cover tape is peeled off by the cover tape peeling mechanism, the electronic component mounted on the carrier tape component storage portion is sent to the pickup opening by the feeding mechanism 22 and is picked up and peeled off by the suction nozzle 18. The covered cover tape is stored in the storage space S of the cover tape storage unit 26. In this way, the electronic component sucked and held by the suction nozzle 18 is mounted on the printed board P.

  By repeatedly taking out the electronic component from the component supply unit 6 and mounting it on the printed circuit board P as described above, the amount of the cover tape that is peeled off and stored in the storage space S of the cover tape storage unit 26 increases. When the cover is full, the cover tape pushes the door 50, and the force for opening the door 50 exceeds the magnetic force of the magnet 58. Then, as shown in FIGS. 5 and 3B, the boundary between the inclined surface 51A of the support shaft 51 and the circular arc part 51B is wound around the opening / closing door 50 in a state where the circular arc part 51B is in contact with the opposing flat part 60C. The opening / closing door 50 is held in a state of being slightly opened by inclining outward from the state of FIG.

  Therefore, with respect to the component supply unit 6, the operator sees a state in which the opening / closing door 50 is slightly opened, and the amount of the cover tape that is peeled off and stored in the storage space S of the cover tape storage portion 26 increases. I can understand that it was full. When the opening / closing door 50 is slightly opened by marking the rear surface 57 or the magnet 58, the operator can easily confirm that the opening / closing door 50 is open by looking at the mark, and thus easily filling the door. Understandable.

  Thus, since the opening / closing door 50 is slightly opened, the operator understands that the door is full, and then removes the cover tape from the storage space S of the cover tape storage portion 26 and leaves only the necessary amount. When the operator further performs an opening operation of the opening / closing door 50, the opening / closing door 50 is in contact with the arcuate portion 51B of the support shaft 51 while the winding base portion 60A and the opposed flat surface portion 60C of the winding portion 60 are in contact with each other. Is opened to the state shown in FIG. 6 and FIG. 3C, and further opened to a substantially horizontal state to the fully opened state shown in FIG. 7 and FIG.

  In this fully opened state, the cover tape is taken out from the storage space S of the cover tape storage portion 26 and cut to leave only a necessary amount, and the opening / closing door 50 is rotated in the reverse direction to cause the magnet 58 to open and close the opening / closing door 50. Adsorb and close.

  Next, a second embodiment in which the opening / closing operation of the opening / closing door 50 is slightly different from the first embodiment will be described with reference to FIG. First, although the opening / closing door 50 is not changed in the second embodiment, the structure of the support shaft that rotatably supports the opening / closing door 50 is different, and will be described below.

  The support shaft 61 has the same diameter as the support shaft 51. As shown in FIG. 8, the support shaft 51 has a circular cross section, that is, a cross section in a direction perpendicular to the longitudinal direction is an arc as shown in FIG. A first inclined surface 61 </ b> A that has a shape formed by two strings and is cut in an oblique direction so as to approach the inside (in the storage space S direction) as it goes upward, and a short connecting to the first inclined surface 61. The connecting portion 61B is formed with a second inclined surface 61C that is cut off in an oblique direction so as to rise toward the right portion and connect to the connecting portion 61B, and an arc portion 61D having a central angle of about 215 degrees. .

  When the amount of the cover tape peeled off and stored in the storage space S of the cover tape storage portion 26 increases and becomes full, the cover tape pushes the opening / closing door 50 and opens and closes the door more than the magnetic force of the magnet 58. Power to open 50 exceeds. Then, as shown in FIG. 8B, the first inclined surface 61 </ b> A of the support shaft 61 and the connecting portion in a state where the arc portion 61 </ b> D of the support shaft 61 is in contact with the opposed flat surface portion 60 </ b> C of the winding portion 60 of the opening / closing door 50. The boundary with 61B contacts and locks the lower part of the winding base 60A of the winding part 60, and the open / close door 50 is held in a slightly opened state from the state of FIG.

  Therefore, with respect to the component supply unit 6, the operator sees a state in which the opening / closing door 50 is slightly opened, and the amount of the cover tape that is peeled off and stored in the storage space S of the cover tape storage portion 26 increases. I can understand that it was full.

  Thus, since the opening / closing door 50 is slightly opened, the operator understands that the door is full, and then removes the cover tape from the storage space S of the cover tape storage portion 26 and leaves only the necessary amount. When the operator further opens the opening / closing door 50, the boundary between the first inclined surface 61A of the support shaft 61 and the connecting portion 61B is moved from the winding base 60A with a slight rotation. After that, when the door 50 can be rotated and opened gently, and the state shown in FIG. 8C is reached, and further opened so as to be substantially horizontal, the second inclined surface 61C and the arc portion 61D The fully opened state shown in FIG. 8 (D) is where the boundary part of the winding part 60A of the winding part 60 and the boundary part of the first arc part 60B coincide with each other.

  In this fully opened state, the cover tape is taken out from the storage space S of the cover tape storage portion 26 and cut to leave only a necessary amount, and the opening / closing door 50 is rotated in the reverse direction to cause the magnet 58 to open and close the opening / closing door 50. Adsorb and close.

  Next, a third embodiment in which the opening / closing operation of the opening / closing door 50 is different from the first and second embodiments will be described with reference to FIG. First, about this 2nd Embodiment, the spindle 71 is exhibiting the column shape, and is the embodiment by which the opening-and-closing door 50 is supported by this spindle 71 so that rotation is possible.

  In other words, it is disposed between the opposing side walls 54 forming the external opening 52 and at a lower position of the side walls 54 so as not to rotate, and the winding portion 72 of the open / close door 50 passes around the support shaft 71. It winds so that it may rotate, and it is comprised so that opening can be opened and closed by making a lower part into a fulcrum.

  A concave groove 26B is formed at the rear position of the bottom wall 26A forming the storage space S of the cover tape storage portion 26, and the lower end 73 of the torsion spring 72 wound around the support shaft 71 is placed in the concave groove 26. The inserted upper end 74 that is movable and bent in the concave groove 26 is inserted into an opening 50 </ b> X opened in the opening / closing door 50 and locked.

  Accordingly, in the state of FIG. 9A, the torsion spring 72 is not urged in the closing direction of the door 50, but the lower end 73 of the torsion spring 72 is inserted into the groove 26 to form the external opening 52. The opening / closing door 50 is attracted by the magnetic force of the magnet 58 embedded in the rear surface 57 of the upper wall 56 to close the external opening 52.

  When the amount of the cover tape peeled off and stored in the storage space S of the cover tape storage portion 26 increases and becomes full, the cover tape pushes the opening / closing door 50 and opens and closes the door more than the magnetic force of the magnet 58. Power to open 50 exceeds. Then, the state shown in FIG. 9A is changed to the state shown in FIG. 9B. That is, the open / close door 50 rotates through the support shaft 71 until the lower end of the torsion spring 72 comes into contact with the front end portion of the concave groove 26B of the bottom wall 26A.

  Therefore, with respect to the component supply unit 6, the operator sees a state in which the opening / closing door 50 is slightly opened, and the amount of the cover tape that is peeled off and stored in the storage space S of the cover tape storage portion 26 increases. I can understand that it was full.

  Thus, since the opening / closing door 50 is slightly opened, the operator understands that the door is full, and then removes the cover tape from the storage space S of the cover tape storage portion 26 and leaves only the necessary amount. When the operator further opens the door 50 against the urging force of the torsion spring 72 in order to cut it, the state shown in FIG. 9C is obtained, and when the door is further opened, It will be in the fully open state shown to 9 (D).

  While the operator holds the open / close door 50 by hand and maintains the fully open state, the cover tape is taken out from the storage space S of the cover tape storage portion 26 and cut to leave only the necessary amount, and the open / close door 50 is reversed. The opening / closing door 50 is attracted to the magnet 58 and closed.

  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.
