Next, as illustrated in FIG. 6C, conveyor driving motor M2 is driven in the forward rotation direction and moves (arrow n) board 14 to the downstream side. When board 14 is detected by board detection sensor S3, conveyor driving motor M2 is stopped and board 14 is stopped at the stop position in work station [A1]. Next, as illustrated in FIG. 6D, after it is confirmed by board detection sensor S4 that overrun of board 14 does not occur, board lower receiver 10#1 is raised (arrow o). Therefore, work station [A1] is in a state of holding board 14.
As described above, in component mounting devices MC6 to MC9 including at least one board transporter constituting a part of board transport lines LA and LB for transporting board 14 from the upstream to the downstream, and the component mounting head for mounting the component on board 14 in the work station in the middle of the board transporter, a board transport method is configured of the following operation steps.
