Multi-cavity type vacuum suction cup

Abstract

The invention discloses a multi-cavity type vacuum suction cup. An air distribution cavity is formed in the center of a cover plate and communicates with an air pipe connector. The bottom face of thecover plate is provided with ventilation grooves which are distributed in a radial manner with the bottom face center of the cover plate as the original point and do not intersect, and the ventilationgrooves communicate with the air distribution cavity. The bottom face edge of the cover plate is provided with a positioning boss. The top face edge of a suction cup body is provided with a positioning groove matched with the positioning boss. The top face of the suction cup body is provided with conical through hole sets which are distributed in a radial manner with the top face center of the suction cup body as the original point, and the conical through hole sets correspond to the ventilation grooves. The bottom face of the suction cup body is vertically provided with a spider web type partition plate assembly, a plurality of suction cup cavities are formed in the bottom face of the suction cup body in a staggered manner through the spider web type partition plate assembly, and the suction cup cavities communicate with correspondingly-arranged conical through holes. According to the multi-cavity type vacuum suction cup, the characteristics of multiple air chambers of royal water lily leaves are used for reference, the capability of adaptation to the workpiece surface through the suction cup is greatly improved, and the probability of adsorption failures due to suction cup edgeleakage is reduced.

Description

technical field [0001] The invention relates to the technical field of vacuum chucks, in particular to a multi-cavity vacuum chuck. Background technique [0002] With the continuous acceleration of the upgrading of my country's industrial structure, more and more enterprises are responding to the decrease in profits brought about by the continuous increase in labor and energy costs by improving the automation level of their own equipment. Vacuum suction cups are widely used as terminal components in automated production equipment. They have the advantages of wide application range, low energy consumption, safe production, and low cost of use. Therefore, they are more and more popular and favored by enterprises. [0003] Judging from the current existing vacuum chucks, they generally have disadvantages such as weak adsorption capacity, poor adaptability, and high requirements for the surface quality of workpieces, which limit their use in some aspects. Therefore, improving t...
