Abstract
A work mounting apparatus according to the present invention comprises a rotating drum composed of separate upper and lower drums, a head unit arranged on the lower drum, a circular work head attached to the head unit and movable in the radial direction of the rotating drum, and a suction nozzle protruding from the outer peripheral surface of the work head toward a workbench. While the lower drum is rotating, the suction nozzle of the work head repeats cycloid motion along the workbench with its posture kept fixed with respect to the workbench. While repeating the cycloid motion, the nozzle receives a work from a work feeder of the workbench by suction, and mounts the work on a printed board on the workbench. The work mounting position on the printed board is determined by the cycle of the cycloid motion and by the distance of movement of the work head in the radial direction of the rotating drum.
