Vacuum chuck and bracket type vacuum adsorption equipment provided with vacuum chuck

Abstract

The invention provides a vacuum chuck and bracket type vacuum adsorption equipment provided with the vacuum chuck. The vacuum chuck is used for adsorbing at least one workpiece and comprises a chuck body with a gas inlet channel, a suction nozzle arranged on one side of the chuck body, and at least one friction gasket arranged on the bottom side of the suction nozzle, wherein the suction nozzle comprises an outer ring part and an inner ring part which are arranged on the bottom side of the suction nozzle; an annular gas gap which is gradually reduced in a direction from the bottom side of the suction nozzle to the gas inlet channel and is communicated with the gas inlet channel is arranged between the outer ring part and the inner ring part; when gas is blown out from the gas inlet channel to the annular gas gap to form an annular vacuum region for adsorbing the workpiece. When the workpiece is adsorbed by the annular vacuum region, the workpiece leans against the friction gaskets so that the disadvantages that the position of the suction nozzle needs to be adjusted additionally and a transportation and loading procedure can be carried out only when a framework fixes a side edge when the vacuum chuck is used for adsorbing the workpiece can be improved.

Description

technical field [0001] The present invention relates to a vacuum suction cup, especially a vacuum suction cup which can be used to absorb porous materials and increase the stability of the suction of the materials by means of friction pads, and also relates to a vacuum suction cup equipped with the vacuum suction cup Vacuum adsorption equipment. Background technique [0002] The prior art about vacuum chucks can be mainly divided into two types: one is a contact vacuum chuck, and the other is a non-contact vacuum chuck. [0003] Generally speaking, the more common and widely used technology is the contact vacuum chuck technology. Its principle is to directly apply the negative pressure generated by the flow of gas from the inlet to the outlet to the workpiece to be adsorbed. To achieve the purpose of absorbing the workpiece. Since the negative pressure is directly applied to the workpiece, when the workpiece is adsorbed on the suction cup, a vacuum-like environment can be ...

Problems solved by technology

In addition, Chinese Taiwan Patent No. 201240009 discloses a non-contact vacuum suction cup. The suction cup is provided with at least one anti-collision pad on the adsorption surface. The purpose of transferring the blank can be achieved, and in the state of use, the blank may still collide with the suction cup or the anti-collision pad on the suction cup due to the vibration generated during the transfer and turning over, causing damage to the surface of the blank. Repeated collisions with crash pads and damage to the surface of the blanks occur
