Problems solved by technology

[0002] In recent years, the sizes of the substrates adsorbed by the vacuum adsorption stages of the related art tend to be diversified. In order to cope with substrates of different sizes, tapes are usually used to close the temporarily unused vacuum suction grooves on the substrate stage, thereby closing the vacuum. The operation of the suction slot is inconvenient and wastes manpower

Abstract

The invention discloses a vacuum adsorption unit and a vacuum adsorption carrier. The vacuum adsorption unit includes: a shell defining an air passage hole inside, and an upper stop surface and a lower stop surface are arranged in the air passage hole; The piston in the air passage hole, the outer peripheral wall of the piston slides and fits with the inner peripheral wall of the air passage hole; The pressure passage is configured such that the pressure relief passage is closed only when the piston moves to the lower abutment surface. The vacuum adsorption unit of the present invention can control the adsorption state of the vacuum adsorption unit according to whether the end of the air passage hole used for adsorption is covered or not, and the different air pressure differences generated on the upper and lower sides of the piston, so as to realize the smooth operation of the vacuum adsorption unit. The automation realizes the purpose of automatically closing the one end of the uncovered gas passage hole used for adsorption.

Description

technical field [0001] The invention relates to the field of vacuum adsorption, in particular to a vacuum adsorption unit and a vacuum adsorption carrier. Background technique [0002] In recent years, the sizes of the substrates adsorbed by the vacuum adsorption stages of the related art tend to be diversified. In order to cope with substrates of different sizes, tapes are usually used to close the temporarily unused vacuum suction grooves on the substrate stage, thereby closing the vacuum. The operation of the suction slot is inconvenient and wastes manpower. Contents of the invention [0003] The present invention aims to solve at least one of the technical problems existing in the prior art. For this reason, the present invention proposes a vacuum adsorption unit, which can control the adsorption state of the vacuum adsorption unit according to the different air pressure differences generated on the upper and lower sides of the piston according to whether the end of t...
