Abstract:
A component is placed by a nozzle of a placing head, which holds the component by means of a negative pressure. A flow path switcher that selectively connects a suction path of the nozzle to a negative pressure source and a positive pressure source is included. During component placement, the flow path switcher switches the nozzle to a positive pressure flow path from a negative pressure flow path to put the nozzle under a positive pressure and detaches the component from the nozzle. Before detection of the component is performed by a component detector, the flow path switcher connects the suction path of the nozzle to the negative pressure flow path to put the suction path under a negative pressure. The component detector that detects the component at a tip of the nozzle is included.

Claim (Index 13):
A component placing method for a component placing device that includes a placing head which has a plurality of nozzles, of which suction paths are put under a negative pressure to hold components, and which moves the plurality of nozzles in turn to a plurality of stations including a component holding and placing station where operation of holding the components or placing the held components at predetermined placement positions on a workpiece is performed by the plurality of nozzles and a component detecting station where detection of the components held by the plurality of nozzles is performed, and a component detector which detects the components, which are at tips of the plurality of nozzles, at the component detecting station, the method comprising:\n moving the plurality of nozzles in turn to the component holding and placing station; holding the components by the plurality of nozzles by putting the suction paths of the plurality of nozzles under a negative pressure; moving the plurality of nozzles in turn to the component holding and placing station and the component detecting station; placing the plurality of components at the plurality of placement positions on the workpiece by putting the suction paths of the plurality of nozzles under a positive pressure at the component holding and placing station to detach the components from the plurality of nozzles; before the nozzles, which have finished placement of the components at the component holding and placing station, reach the component detecting station, putting the suction paths of the nozzles, which have finished the placement of the components, under a negative pressure; examining presence or absence of take-away components for the plurality of nozzles at the component detecting station; and in a case where the take-away components are detected, discarding the take-away components at a predetermined component collection position.
