ABSTRACT:
A work mounting apparatus or component mounting apparatus according to the present invention comprises a lower drum of a rotating drum, a head unit arranged on the outer periphery of the lower drum, a circular work head or component head attached to the head unit, 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 or component, such as an electronic component from a work feeder of the workbench by suction, and mounts the work on a printed board on the workbench. The work head is rotated for a predetermined rotational angle during the process in which the suction nozzle moves from the work feeder toward the printed board after the work is received, or in the process in which the nozzle moves from the printed board toward the work feeder after the work is mounted. Thus, the region for the cycloid motion of the suction nozzle is upwardly separated from the workbench.
