Circuit-component transferring apparatus

摘要

A circuit-component transferring apparatus including a sucker which holds a circuit component by applying a negative pressure thereto; a sucker moving device which supports the sucker such that the sucker is movable upward and downward relative thereto and which moves the sucker in a direction intersecting a direction of the upward and downward movements of the sucker; an elevating and lowering device which includes a drive member and which moves the sucker upward and downward by elevating and lowering the drive member; a pressure switching valve which is supported by the sucker moving device and which includes a movable switch member; and a valve control device which is actuated by the elevating and lowering device and which is selectively placed in one of a component-sucking control state in which, when the elevating and lowering device moves the sucker downward by lowering the drive member, the valve control device moves the switch member to a negative-pressure supplying position at which the switch valve permits a negative pressure to be supplied to the sucker and a component-releasing control state in which, when the elevating and lowering device moves the sucker downward by lowering the drive member, the valve control device moves the switch member to a negative-pressure removing position at which the switch valve permits a pressure not lower than an atmospheric pressure to be supplied to the sucker.
