Vacuum suction cup and vacuum adsorption structure

Abstract

The invention discloses a vacuum suction cup and a vacuum adsorption structure. The vacuum suction cup comprises a suction cup bottom face, an airtight gasket and a rear cover. An annular step is arranged on the rear cover, and the airtight gasket is arranged on the annular step between the suction cup bottom face and the rear cover. The suction cup bottom face and the rear cover are connected through a fastener, and a groove is formed in the inner side of the suction cup bottom face. A separation strip is arranged on the groove, and the separation strip divides the groove into multiple cavityareas. The separation strip is attached to the inner side of the rear cover, and first through holes are formed in the positions, corresponding to the cavity areas, of the rear cover correspondingly.A same number of second through holes are formed in the positions, corresponding to the cavity areas, of the suction cup bottom face, and hollow fixed columns are arranged at the positions, corresponding to the second through holes, of the outer side of the suction cup bottom face. According to the vacuum suction cup and the vacuum adsorption structure, the multiple cavity areas are arranged in the suction cup bottom face, all the cavity areas do not influence one another, and therefore adsorption force is evenly distributed at the adsorption ends of the fixed columns.

Description

technical field [0001] The invention relates to the technical field of negative pressure adsorption, in particular to a vacuum suction cup and a vacuum adsorption structure. Background technique [0002] Vacuum suction cup, also known as vacuum spreader, is one of the actuators of vacuum equipment. Vacuum suction cups are usually made of nitrile rubber and have a large tearing force, so they are widely used in various vacuum holding equipment, such as in construction, printing, glass and other industries, to achieve holding and transporting thin and thin glass, paper, etc. The task of light goods. [0003] The suction cup usually includes a disk body and a suction head, the disk body is provided with an inner cavity, and the inner cavity is respectively connected with the suction head and the vacuuming device. If there is only one suction head, it can only absorb small-sized objects, and it is difficult to maintain balance during adsorption; if there are multiple suction h...

AI Technical Summary

Problems solved by technology

If there is only one suction head, it can only absorb small-sized objects, and it is difficult to maintain balance during adsorption; if there are multiple suction heads, uneven suction is likely to occur between the suction heads, resulting in uneven force on the suctioned objects. In severe cases, the surface of the sucked object will be damaged
