More in the component supply device 50 includes a receiving portion with respect to the pallet 52, 52 housed in the horizontal direction in two lines arranged in 60, two each lead mechanism for driving independently 70,70, lifting mechanism 7 9, 79, component transfer mechanisms 80 and 80 are arranged, and thereby two independent electronic component supply paths are formed from the storage unit 60 to the mounting machine body 10.

  Next, the operation of the mounting machine will be described focusing on the operation until the electronic component Q is supplied from the component supply device 50 to the mounting machine body 10. In the component supply apparatus 50, two component supply paths are formed as described above. However, since each component supply path performs substantially the same operation, two component supply paths are used in the following description. The parts supply route will be described collectively.

  First, in the component supply device 50, a large number of pallets 52 are stored in a plurality of upper and lower stages in two horizontal rows in the storage unit 60. Note that a component tray 51 in which electronic components are stored and held in a matrix is placed on the pallet 52 in a fixed position.

  From this state, when the drawer mechanism 70 is moved up and down by driving the lifting mechanism 79, the both-side rails 71 of the drawer mechanism 70 are moved to the height position of the predetermined pallet 52 to be pulled out, and the leading ends of the both-side rails 71 are moved. It is arranged opposite to both sides of a predetermined pallet 52.

  Subsequently, the clamp mechanism 76 in the drawer mechanism 70 moves to the pallet 52 side along the intermediate rail 75, and the grip portion 521 of the pallet 52 is gripped by the clamp 761 of the clamp mechanism 76.

  After the clamp 761 is gripped in this way, the clamp mechanism 76 moves in the pull-out direction along the intermediate rail 75, whereby the pallet 52 is pulled out from the storage portion 60 onto the both-side rails 71, 71, and the rails 71, 71 It moves along 71.

When the pallet 52 is moved to a position of Jo Tokoro, if necessary, by extraction mechanism 70 is raised by the drive of the lifting mechanism 79, the electronic component Q of the pallet 52 in the part tray 51 is, the component transfer mechanisms 80 The transfer head 851 moves to a pickup area (pickup area).

  Next, as shown in FIG. 8, the head unit 85 moves to the pickup area along the arm 81, and the two transfer heads 851 and 851 in the head unit 85 are held on the predetermined tray 2 held on the component tray 51 of the pallet 52. It is arranged at a position corresponding to one electronic component. At this time, the alignment of the transfer heads 851 and 851 with respect to the electronic components Q and Q in the Y-axis direction is performed by moving the pallet 52 in the loading / unloading direction by the drawing mechanism 70, and the alignment in the X-axis direction is needless to say. This is performed by moving the head unit 85 along the arm 81.

  Thereafter, the nozzles 90 and 90 of the transfer heads 851 and 851 advance and simultaneously hold and hold the corresponding two electronic components Q and Q, respectively.

  With the electronic components Q and Q held by the heads 851 and 851, the head unit 85 moves to the mounting machine body 10 side along the arm 81 as shown in FIG. 9, and the head unit 85 is lowered. It is arranged above the mounting table 86.

  Next, when the nozzles 90, 90 of the head unit 85 advance and release the suction, the electronic components Q, Q are transferred to the component mounting table 86, and simultaneously with the transfer, the suction portion of the component mounting table 86 is transferred. Electronic parts Q and Q are sucked and held by 864 and 864, respectively.

  Subsequently, as shown in FIG. 10, the head unit 85 moves to the pickup area along the arm 81 to transfer the next electronic component Q, while the component mounting table 86 holds the electronic components Q and Q by suction. Rise in state. As a result, the electronic components Q and Q of the component mounting table 86 are arranged in the operating region M1 (component supply position) of the mounting head 41 in the mounting machine body 10.

  Thereafter, the head unit 40 of the mounting machine body 10 moves up to the raised component mounting table 86. Subsequently, the suction to the electronic components Q and Q by the component mounting table 86 is released, and the electronic components Q and Q are sucked and held by the suction nozzles 41a of the predetermined heads 41 in the head unit 40.

  The electronic component Q held by the mounting head 41 moves to above the printed circuit board P arranged on the conveyor 20 and is mounted at a predetermined position on the printed circuit board P.

  After the electronic component is delivered to the mounting head 41, the component mounting table 86 descends, returns to the operation area M <b> 2 of the transfer head 851, and waits until the next electronic component is transferred by the transfer head 851.

  In this way, an electronic component is appropriately supplied from the component supply device 50 to the mounting machine body 10, and the electronic component is mounted on the printed circuit board P by the mounting machine body 10 and supplied from the tape feeder 31 as described above. Small electronic components are mounted by the mounting head 41.

  When the mounting of the electronic components on the printed circuit board P is completed, the printed circuit board P is moved by a predetermined amount along the transport line X1 by the conveyor 20, and the next unprinted printed circuit board P is arranged at the mounting position of the mounting machine body 10. Is done.

  On the other hand, when all the electronic components are supplied from the pallet 52 in the pickup area to the mounter body 10 in the component supply device 50, the pallet 52 is returned to the predetermined pallet support portion 61 of the storage unit 60. That is, the drawer mechanism 70 is lowered by driving the lifting mechanism 79 as necessary, and the pallet 52 is disposed at a height position corresponding to the predetermined pallet support portion 61. Subsequently, the clamp mechanism 76 moves in the direction opposite to the drawing direction, and the pallet 52 is pushed into the predetermined pallet support portion 61. Thereafter, gripping of the pallet gripping portion 521 by the clamp 761 of the clamp mechanism 76 is released. In this way, the pallet 52 on which the empty tray 51 is placed is returned to the storage unit 60.

  Here, the component supply apparatus of this embodiment can supply electronic components freely by two independent component supply paths. Therefore, the supply of the electronic component through one component supply path and the supply of the electronic component through the other component supply path can be performed alternately at different times, and can be performed in parallel. It can also be done separately. In the present embodiment, if necessary, different types of electronic components may be stored in one pallet 52 and the other pallet 52, or different types of electronic components may be stored in one pallet 52. You may make it leave.

  As described above, according to the present embodiment, the electronic component is sucked and picked up by the transfer head 851 from the component tray 51 drawn to the pickup area, and the transfer head 851 is moved along the arm 81 to the mounting machine body 10. Therefore, the electronic component can be transferred from the component tray 51 to the mounting machine body 10 side while only the upper surface side of the electronic component is sucked. As described above, since the electronic component can be transferred only by the upper surface suction, for example, all types of electronic components can be securely held as compared with the case where the lower surface side of the electronic component is sucked and held. The electronic component can be stably supplied to the mounting machine body 10.

  In the present embodiment, since the transfer head 851 is transferred to the mounting machine main body 10 while the electronic component is picked up from the component tray 51 by the transfer head 851, the shuttle will be described in detail below. Like a transfer-type component supply device, it is possible to prevent excessive pressing of the transfer head against the electronic component. That is, the shuttle transfer type component supply apparatus transfers electronic components from the component tray to the shuttle and moves the shuttle to the mounting machine main body side. In this shuttle transfer type component supply apparatus, when an electronic component is transferred from the component tray to the shuttle, the electronic component in the component tray is sucked by air suction by the suction nozzle of the transfer head, and the transfer head is shuttled. It is moved to the top, the suction is released, and the electronic component is transferred onto the shuttle. However, since the height position of the shuttle is fixed, when an electronic component is transferred from the nozzle of the transfer head onto the shuttle, for example, when an electronic component having a large height is employed, The height dimension of the electronic component is larger than the dimension between the nozzle of the transfer head and the shuttle, and a transfer process (hard landing) is performed in which the electronic component is excessively pressed against the shuttle by the nozzle of the transfer head. Become.

  On the other hand, in the present embodiment, since the transfer head 851 is transferred from the component tray 51 to the mounting machine body 10 side while being picked up by the transfer head 851, the electronic components in the tray are It can be transferred directly to the mounting machine main body 10 side without being transferred to the shuttle. For this reason, it is possible to prevent the electronic component from being pressed by the suction nozzle when the electronic component is transferred to the shuttle.

  In this embodiment, since the component mounting table 86 is provided at the component supply position, the electronic component is transferred from the transfer head to the mounting table 86 when the electronic component is transferred from the transfer head 851 to the component mounting table 86. The transfer process by the transfer head 851 is completed. For this reason, the transfer head 851 can return to the pickup area immediately after the electronic component is transferred to the component mounting table 86 and can start the next transfer operation, and can efficiently transfer the component.

  In this embodiment, since the component mounting table 86 is provided so as to be movable up and down, when an electronic component is transferred from the transfer head 851 to the component mounting table 86, the component mounting table 86 is matched to the height dimension of the electronic component. The vertical position of the mounting table 86 can be adjusted, and even when an electronic component having a large height is adopted, the nozzle 90 of the transfer head 851 prevents the electronic component from being pressed against the component mounting table 86.
