Abstract: A nozzle holder that detachably holds a nozzle in a lower end portion of a main shaft is configured to have a tubular shape having an insertion hole into which an installed portion of the nozzle is inserted, and to include a holder tube portion in which an opening portion leading to the insertion hole is formed on one side surface of the holder tube portion, a clamp lever which has an engaging portion engaged via the opening portion with the installed portion of the nozzle inserted into the insertion hole, and a clamp spring which biases the engaging portion to the installed portion of the nozzle inserted into the insertion hole.

Abstract: A component placing device has a configuration where a plurality of nozzle shafts are moved in turn to a plurality of stations including a component holding and placing station and a component detecting station by rotating a rotating object having the plurality of nozzle shafts, in which nozzles are installed, about a rotation axis. A configuration where a flow path switcher, which selectively connects a suction path of each of the nozzles to a positive pressure source and to a negative pressure source by movement of a spool, is disposed on an inside of a corresponding one of the nozzle shafts, and air for power to drive the spool is supplied to the rotating object via a manifold, in which a communication plug for power air that comes into contact with an exterior surface of the rotating object is provided, is adopted.

Abstract: A nozzle holder is configured to include an insertion hole for inserting and storing a cartridge from an entrance thereof, a tubular holder tube portion having a vent hole for introducing a negative pressure into the insertion hole, and a clamp lever in which an engaging portion engaged with an engaged portion of the nozzle inserted into the insertion hole in a state where the entrance of the insertion hole is blocked, is formed. Accordingly, when the nozzle is detached from the nozzle holder, the clamp lever prevents the cartridge from coming off the insertion hole by being displaced toward the insertion hole.

Abstract: A component mounter includes a side imaging camera that is provided to be integral with the placing head having a plurality of suction nozzles, that moves relatively with respect to the plurality of suction nozzles, and thereby that images, from a side, peripheral regions of front ends of the plurality of suction nozzles, respectively, in order. Incidentally, a component presence/absence determiner (determiner) determines the presence or absence of a component sucked on the front end of the suction nozzle, based on primary image data obtained by the side imaging camera and the calculator calculates a thickness of the component sucked on the front end of the suction nozzle, based on secondary image data obtained by the side imaging camera.

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.
