A Vacuum Suction Cup for Ultra-thin Optical Parts

Abstract

The invention provides a vacuum suction cup for absorbing ultra-thin optical parts, comprising: a vacuum passage part, which is disc-shaped, has a vacuum chamber arranged inside, and is arranged on the upper surface of the vacuum chamber through the center of the circle and uniformly arranged along the diameter direction The first through hole and the second through hole arranged in the center of the lower surface of the vacuum chamber; the rubber adsorption part is arranged above the vacuum passage part, which is disc-shaped, has an annular groove and is arranged below the annular groove with the The first through hole is aligned with the through hole; and the vacuum generator part is arranged under the vacuum passage part, which is disc-shaped, and the vacuum generator is arranged inside, and the center of the upper surface is provided with the second through hole. Aligned round holes, wherein the vacuum generator part, the rubber suction part and the vacuum passage part are sealed with sealant, and screwed and fixed with screws and nuts to form an integrated structure.

Description

technical field [0001] The invention relates to a vacuum chuck, in particular to a vacuum chuck for sucking ultra-thin optical parts. Background technique [0002] In today's increasingly developed industry, vacuum technology has been widely used in various industries and has achieved various important achievements. Traditional vacuum suction cups can be divided into flexible vacuum suction cups and rigid vacuum suction cups according to their properties. Although flexible vacuum suction cups can fully fit the adsorbed objects when absorbing objects, the deformation of the vacuum suction cups is relatively large, resulting in the suction of objects. The deformation is also large, especially when the picked-up object is an ultra-thin part. Rigid vacuum suction cups are the opposite. Although the deformation of the vacuum suction cup is small, when absorbing rigid objects, there will be gaps between the bonding surfaces, and air leakage will occur, resulting in unreliable ads...

AI Technical Summary

Problems solved by technology

Traditional vacuum suction cups can be divided into flexible vacuum suction cups and rigid vacuum suction cups according to their properties. Although flexible vacuum suction cups can fully fit the adsorbed objects when absorbing objects, the deformation of the vacuum suction cups is relatively large, resulting in the suction of objects. The deformation is also large, especially when the absorbed object is an ultra-thin part

Rigid vacuum suction cups are the opposite. Although the deformation of the vacuum suction cups is small, when absorbing rigid objects, there will be gaps between the bonding surfaces, and air leakage will occur, resulting in unreliable adsorption.

Moreover, the traditional vacuum suction cup is connected separately from the vacuum generator, which occupies a large space and has a complicated structure.
