Abstract:
1. A part mounting apparatus comprising: a pickup head having a pickup tool for picking up a part; a pickup head supporting unit supporting the pickup head; a pickup head supporting arm having one end portion where the pickup head is disposed and an other end portion rotatably mounted to the pickup head supporting unit; a pickup head inverting unit vertically inverting the pickup head with respect to the pickup head supporting unit; a pickup tool rotating unit rotating the pickup tool about a rotational axis of the pickup tool; and a shaft disposed on the pickup head supporting arm so as to be movable in a direction of the rotational axis, both end portions of the shaft respectively projecting from the both end portions of the pickup head supporting arm, wherein the pickup tool rotating unit includes a driving force generating unit and a driving force transmitting unit transmitting a driving force of the driving force generating unit as a rotational force of the pickup tool; and the driving force generating unit is disposed on the pickup head supporting unit, wherein the driving force generating unit imparts a force for moving in the direction of the rotational axis of the pickup head supporting arm from one end portion of the shaft to the shaft; and the driving force transmitting unit converts the translatory movement of an other end portion of the shaft into rotary movement of the pickup tool, wherein the driving force generating unit causes a driven member disposed at one end portion of the shaft to follow rotary movement of an eccentric cam disposed on the pickup head supporting unit so as to impart to the shaft a force for moving in the direction of the rotational axis of the pickup head supporting arm.
