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 7):
A component placing device comprising:\n a placing head that has a plurality of nozzles of which suction paths are put under a negative pressure to hold components and that 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; a plurality of flow path switchers, each of which is disposed for each of the nozzles and selectively connects each of the suction paths of the nozzles to a negative pressure flow path leading to a negative pressure source and a positive pressure flow path leading to a positive pressure source; and a component detector that detects the components, which are at tips of the nozzles, at the component detecting station, wherein in a case where work of placing the components is performed by the nozzles at the component holding and placing station, the flow path switchers switch the suction paths of the nozzles, which perform the work of placing the components, to a state connected to the positive pressure flow path from a state connected to the negative pressure flow path to put the suction paths under a positive pressure, such that the components are detached from the nozzles of which the suction paths are put under a positive pressure, before the nozzles, of which the suction paths are put under a positive pressure, reach the component detecting station, the flow path switchers connect the suction paths to the negative pressure flow path to put the suction paths under a negative pressure, and in a case where take-away components, which remain in a state of being attached to the nozzles without being detached from the nozzles in the components placement, are detected by the component detector, the take-away components are discarded at a predetermined component collection position.
