<Mounting work with electronic component mounting machine>
With the above-described configuration, the mounting machine 16 can perform an electronic component mounting operation with the mounting head 28 on the circuit board held by the transport device 26. More specifically, the circuit board is first transported to the mounting work position by the transport device 26, and the circuit board is fixedly held at that position. Next, the mounting device 28 is moved onto the circuit board by the moving device 30, and the circuit board is imaged by the mark camera 130. By the imaging, the type of the circuit board and the holding position error of the circuit board by the transfer device 26 are acquired. The electronic component corresponding to the acquired type of the circuit board is supplied by the tape feeder 74 of the supply device 32, and the mounting head 28 is moved by the moving device 30 to the supply position of the circuit component. Thereby, the circuit component is sucked and held by the suction nozzle 50 of the mounting head 28. In the present mounting machine 16, as described above, the two suction nozzles 50 can simultaneously suck electronic components from the two tape feeders 74.

  Subsequently, the mounting head 28 holding the electronic component is moved onto the parts camera 132 by the moving device 30, and the electronic component held by the mounting head 28 is imaged by the parts camera 132. The holding position error of the electronic component is acquired by the imaging. The moving device 30 moves the mounting head 28 to the mounting position on the circuit board, and the mounting head 28 rotates the mounting nozzle 50 based on the holding position error between the circuit board and the electronic component. Installed.

<Adjustment of electronic component supply position with tape feeder>
As described above, the mounting machine 16 sucks and holds the electronic component supplied by the tape feeder 74 of the supply device 32 by the suction nozzle 50 of the mounting head 28, and places the sucked and held electronic component on the circuit board. It is configured to be worn. In the mounting machine configured as described above, it is important to appropriately suck the electronic component by the suction nozzle 50, and it is desirable that the suction nozzle 50 sucks a preset portion of the electronic component. For this reason, it is desirable that the tape feeder 74 supplies the electronic component at a predetermined position. In order to define the supply position of the electronic component, the supply device 32 has the tape feeder 74 as described above. A mechanism for defining the position is provided.

  However, even if the position of the tape feeder 74 is defined by such a mechanism, the tape feeder 74 may slightly deviate from the predetermined position. As the tape feeder 74 is deviated, the supply position of the electronic component is also predetermined. There may be deviation from the position. In such a case, there is a possibility that the electronic component cannot be properly sucked by the suction nozzle 50. In particular, in the present mounting machine 16, it is possible to simultaneously suck electronic components from the two tape feeders 74 by the two suction nozzles 50. If the supply positions of the two tape feeders 74 are shifted, those 2 The distance between the supply positions of the two tape feeders 74 may change from the specific distance L. In such a case, there is a possibility that simultaneous suction of electronic components by the two suction nozzles 50 cannot be performed properly.

  Therefore, in this work machine 16, supply position adjustment control for adjusting the supply position of the electronic component is performed in order to correct the deviation of the supply position of the electronic component by the tape feeder 74. In this control, the supply position of the electronic component is adjusted by controlling the operation of the feeding device 76 of the tape feeder 74 and the rotation motor 110 of the positioning mechanism of the tape feeder 74 based on the deviation amount of the supply position. More specifically, first, the holding position of the electronic component by the suction head 50 is determined from the image data of the electronic component imaged by the parts camera 132 during the mounting operation, that is, the image data of the electronic component that is sucked and held by the suction nozzle 50. Get the error. Then, based on the holding position error, a deviation amount in the X-axis direction and a deviation amount in the Y-axis direction of the electronic component supply position are calculated. These processes are performed in the supply position deviation amount acquisition unit 150 of the controller 142 shown in FIG.

  Then, the position of the tape feeder 74 is adjusted in the X-axis direction by controlling the operation of the rotary motor 110 based on the obtained shift amount of the electronic component supply position in the X-axis direction, and the electronic component supply position is adjusted. Is adjusted in the X-axis direction. This process is performed in the tape feeder position adjustment unit 152 of the controller 142 shown in FIG. Further, by controlling the operation of the feeding device 76 of the tape feeder 74 based on the obtained shift amount of the electronic component supply position in the Y-axis direction, the feed amount of the taped component 70 is adjusted to supply the electronic component. Adjust the position in the Y-axis direction. This process is performed in the electronic component supply position adjusting unit 154 of the controller 142 shown in FIG. By the above processing, it is possible to eliminate the deviation of the electronic component supply position, and it is possible to appropriately suck the electronic component by the suction nozzle 50.
