Abstract:
1. A suction nozzle for holding a component by suction, the suction nozzle comprising: an outer nozzle member defining a first suction passage for communicating with a suction source at one end thereof and a nozzle body accommodation bore; a nozzle body for holding the component at a distal end face thereof by suction, the nozzle body having a proximal side accommodated in the nozzle body accommodation bore so as to be slidable in a direction of an axis thereof, a distal side protruding from the outer nozzle member, and a first cylindrical portion protruding from a proximal end face thereof, the nozzle body defining a second suction passage extending in the axis direction thereof for communicating with the first suction passage, and the second suction passage having an opening at the distal end face of the nozzle body; and an urging member for urging the nozzle body in a direction away from the outer nozzle member, the urging member being accommodated in an urging member accommodation chamber defined by at least a wall surface of the nozzle body accommodation bore and a proximal end face of the nozzle body, the urging member accommodation chamber being shut from the first and second passages and communicated with atmosphere, wherein the nozzle body is movable against an urging force of the urging member from a first position where a distal end face of the first cylindrical portion is apart from a bottom wall surface of the nozzle body accommodation bore, to a second position where the distal end face of the first cylindrical portion contacts against the bottom wall surface of the nozzle body accommodation bore, wherein the nozzle body defines at least one lateral passage extending in a direction crossing the axis thereof, and wherein the lateral passage communicates with the second suction passage at one end thereof and communicates with the other end of the first suction passage of the outer nozzle member at the other end thereof.
