Problems solved by technology

[0002] The traditional LED sorting machine generally adopts a mechanical fixing method when fixing the wafer. Although the mechanical fixing method is used, although the fixing is firm, the structure is complicated. When the wafer is taken out, the mechanical fixing device needs to be opened first. Then take it, which reduces the processing efficiency, and the mechanical fixing method is easy to cause damage to the LED chip

Abstract

The invention discloses a vacuum hole bracket for an LED wafer automatic sorting machine. The vacuum hole bracket comprises a vacuum bracket body, wherein a vacuum hole bracket sealing cover is connected below the vacuum bracket body, and a gap is formed between the vacuum bracket body and the vacuum hole bracket sealing cover to form a negative pressure cavity; and the vacuum hole bracket is provided with an upper surface and a lower surface, the upper surface is a plane, the lower surface is a plane, a plurality of micropores are distributed in the lower surface of the vacuum hole bracket, the multiple micropores are arranged in a hexagonal shape, the arrangement shape of the micropores is matched with the shape of a wafer, the negative pressure cavity generates larger adsorption force by the negative pressure through the micropores, a blue film is adsorbed on the upper surface of the vacuum hole bracket, and the adsorption force generated by the plurality of micropores is uniform, so that the blue film is not deformed, and the flatness of the blue film of the welding wafer is guaranteed.

Description

technical field [0001] The invention relates to an automatic sorting machine for LED chips, in particular to a vacuum hole bracket for an automatic sorting machine for LED chips, which belongs to the technical field of LED chip manufacturing. Background technique [0002] The traditional LED sorting machine generally adopts a mechanical fixing method when fixing the wafer. Although the mechanical fixing method is used, although the fixing is firm, the structure is complicated. When the wafer is taken out, the mechanical fixing device needs to be opened first. Then take it, which reduces the processing efficiency, and the mechanical fixing method is easy to cause damage to the LED chip. Contents of the invention [0003] The problem to be solved by the present invention is to provide a vacuum hole bracket for an automatic LED wafer sorting machine in view of the above deficiencies. The vacuum hole bracket uses negative pressure to generate a large adsorption force in the mi...
