Abstract

The invention relates to swirl non-contact type sucker, belonging to semiconductor manufacture technical field, which comprises a cup body, an intracavity aerodynamic body and a nozzle, wherein the cup body inner is a cylindrical hole body; the intracavity aerodynamic body is arranged at the bottom of the cup body; the column annular clearance is reserved between the cup body and the intracavity aerodynamic body; a nozzle is arranged at the lateral face near the bottom of the cup body. The invention can realize two purpose of workpiece sucking and guaranteed non-contact of workpiece and sucker. The swirl non-contact type sucker has the advantages of simple technology, small air consumption and big suction.

Description

technical field [0001] The invention relates to a suction cup in the technical field of conveying equipment, in particular to a swirling flow non-contact suction cup. Background technique [0002] Due to the development of the semiconductor industry, the traditional contact handling method is no longer suitable for handling semiconductor wafers, plasma display substrates, liquid crystal display substrates and other devices. The improvement of traditional conveying methods can no longer meet the needs of conveying, and improving the yield rate of products is the goal that LCD factories are constantly pursuing. According to the characteristics of liquid crystal substrates, non-contact conveying equipment can enter people's field of vision. Conveying and cleaning have become indispensable. [0003] After searching the literature of the prior art, it is found that the Chinese Utility Model Patent Publication No. is CN2269673, which mentions a pneumatic suction machine, which is...
