Work mounting apparatus

摘要

A work mounting apparatus according to the present invention comprises a lower drum (28) of a rotating drum (4), a head unit (68) arranged on the outer periphery of the lower drum (28), a circular work head (70) attached to the head unit (68), and a suction nozzle (78) protruding from the outer peripheral surface of the work head (78) toward a workbench (2). While the lower drum (28) is rotating, the suction nozzle (78) of the work head (70) repeats cycloid motion along the workbench (2) with its posture kept fixed with respect to the workbench (2). While repeating the cycloid motion, the nozzle (78) receives a work (W) from a work feeder (6) of the workbench (2) by suction, and mounts the work (W) on a printed board (B) on the workbench (2). The work head (70) is rotated for a predetermined rotational angle during the process in which the suction nozzle (78) moves from the work feeder (6) toward the printed board (B) after the work (W) is received, or in the process in which the nozzle (78) moves from the printed board (B) toward the work feeder (6) after the work (W) is mounted. Thus, the region for the cycloid motion of the suction nozzle (78) is upwardly separated from the workbench (2).
