Suction nozzle

Abstract

In a suction nozzle 66 which sucks and holds a component 150 on a suction surface by using negative pressure air and detaches the sucked and held component from the suction surface by using positive pressure air, the positive pressure air and the negative pressure air used when the component is held and detached selectively flow through through-holes 90, 94 and 96, air flow path 116, or the like. In addition, a rod 110 is held to be capable of being advanced and retracted toward the suction surface in an inside section of the suction nozzle. The rod protrudes from the suction surface by the positive pressure air flowing through the air flow path and is retracted to the inside section of the suction nozzle when the negative pressure flows through the air flow path. In other words, the through-hole, the air flow path, or the like is shared as a mechanism for moving the rod and a mechanism for sucking and holding the component by the suction nozzle. Accordingly, it is possible to make the device compact, simple or the like and to improve practicality of the suction nozzle.
