A work mounting apparatus comprises a nozzle head which repeatedly makes cycloid motion as a drum rotates while being held in a fixed orientation, a suction nozzle projecting downward from the nozzle head for receiving and mounting a work, and a liquid damper-type balancer for the nozzle head. The balancer contains a movable weight which relatively vibrates so as to cancel out vibration of the nozzle head.

Work mounting apparatus

In a parts mounting apparatus, suction nozzles are mounted on a rotating carrier driven by a motor. With rotation of the rotating carrier, parts are sucked by the nozzles at a feed station and carried to a mounting station where the parts such as electronic parts are mounted on substrates, for example. A counter counts output pulses from an encoder mounted in the motor driving the rotating carrier. A microcomputer determines the rotational speed and rotational position of the rotating carrier from the count value of the counter. Based on the result of the determination, the microcomputer calculates a timing for delivering a signal for switching the nozzles between two different pneumatic states.

Parts mounting apparatus

A work or component mounting apparatus according to the present invention comprises a rotating drum arranged above a workbench and divided into upper and lower drums, a head unit detachably mounted to the lower drum of the rotating drum, a circular work head (or, in other words, a component head) attached to the head unit, a suction nozzle protruding from the outer peripheral surface of the work head toward the workbench, and a controller housed in the upper drum of the rotating drum for controlling the turning motion of the work head and the supply of suction pressure to the suction nozzle. 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.
