1. An automatic backup pin arrangement system for a component mounting machine, comprising:
a backup plate on which backup pins are placed, the backup pins holding, from below, a circuit board on which a component is mounted;
an XY-robot configured to perform a component mounting operation of mounting the component on the circuit board and an automatic backup pin arrangement operation of automatically arranging the backup pins on the backup plate; and
a control device configured to control an operation of the XY-robot,
wherein the control device is configured to control the XY-robot to
use at least a part of a region of the backup plate not facing a lower surface of the circuit board, as a stock area for storing the backup pins,
pick up the backup pins stored in the stock area, and
automatically arrange the backup pins at positions of the backup plate designated in a production job, and
the control device is configured to change the arrangement of the backup pins by
acquiring information on the mounted component on a lower surface side of the circuit board when the production job is switched,
determining whether there is a free space where the unnecessary backup pin removed from the backup plate is retracted to the stock area, and
when it is determined that there is no free space where an unnecessary backup pin removed from the backup plate is retracted to the stock area, controlling the XY-robot to
use as a retraction area, at least a part of a region of the backup plate facing a lower surface of the circuit board, which does not interfere with a mounted component on a lower surface side of the circuit board, and
retract the unnecessary backup pin that cannot be retracted to the stock area to the retraction area.
