US 2012/0132776 A1 · SUCTION DEVICE FOR ELECTRONIC COMPONENTS

Abstract

A suction device includes a suction cup, an operating member, a sealing member, an elastic member, and a stopping member. A gas hole is defined in the suction cup. A through hole is defined in the operating member, communicating with the gas hole. The suction cup is fixed to an end of the operating member. The sealing member includes a sealing portion to seal the gas hole, and a connection post connected to the sealing portion. A cross-sectional area of the connection post is smaller than that of the gas hole or the through hole. An end of the connection post extends through the gas hole and the through hole, and protrudes out from the operating member. The elastic member is sleeved on the connection post. The stopping member is fixed to the connection post. Opposite ends of the elastic member resist the operating member and the stopping member, respectively.
