  • Patent number: 10051770
    Abstract: A system including at least one inspection machine and an NG board discharge machine which moves an NG board to a checking position visible to a worker. The system acquires positional information of a circuit board during conveyance, and stores the NG board by associating a work result for the NG board with the positional information. In this manner, the positional information of the NG board is acquired. Based on the positional information, it is determined whether or not the circuit board conveyed to the NG board discharge machine is the NG board. When the circuit board conveyed to the NG board discharge machine is the NG board, a checking-purpose working machine discharges the NG board to the checking position.

  • Publication number: 20180228067
    Abstract: A control device that determines tape reference positions having a fixed positional relationship with first origin positions based on first positions of tape feeding devices when leading ends of carrier tapes are detected and the first origin positions of the tape feeding devices immediately before leading end detection. Then, after determination of the tape reference positions, an interval between cavities is calculated based on a detection cycle of transmitted light amounts detected by light being transmitted through empty cavities. In addition, when a phenomenon, in which a detected light amount is equal to or smaller than a threshold, consecutively occurs after calculation of the interval between the cavities, it is detected that components are accommodated in the cavities.

  • Publication number: 20180201446
    Abstract: A work machine including a conveyor belt is rotated such that a protruding section is positioned on the upstream side of an end face on the opposite side to a conveyance direction of a circuit board while the circuit board is clamped by a clamping device. Thereby, it is possible to prevent interference between the projecting portion and the circuit board, and reliably push out the circuit board toward the downstream side using the protruding section. In multiple work machines, the circuit boards are simultaneously conveyed after a clamp of the circuit board is released. Thereby, there is no need for the work machine on the upstream side to be on standby for conveyance of the circuit board using the work machine on the downstream side and it is possible to prevent a reduction of throughput.
