Full-automatic needling crystal grain sorting equipment

Abstract

The invention discloses full-automatic needling crystal grain sorting equipment. The equipment comprises a rack, a controller, a lower blue film fixing mechanism, an ejector pin mechanism, an upper blue film fixing mechanism and a CCD visual mechanism, wherein the controller is arranged on the rack. Through the arrangement of the lower blue film fixing mechanism, the ejector pin mechanism, the upper blue film fixing mechanism and the CCD visual mechanism, crystal grains of a lower blue film can be directly ejected to a new blue film through the ejector pin mechanism when the blue film is sorted; compared with an existing swing arm type vacuum adsorption mode, the working efficiency is greatly improved, and the requirement for subsequent productivity can be met; and meanwhile, when the crystal grains are sorted, the crystal grains on the blue film can be monitored through the CCD visual mechanism, incomplete and bad crystal grains are removed in time, the quality of the crystal grains on the new blue film is guaranteed, and the influence on the subsequent process of the blue film is avoided.

Description

technical field [0001] The invention relates to the technology in the field of blue film grain separation, in particular to a fully automatic acupuncture grain separation equipment. Background technique [0002] In the LED industry, it is necessary to go through various sub-processes from the grain to the finished product, such as epitaxial growth, electrode plating, grinding, cutting, point measurement, sorting, etc. When sorting the grain, it is necessary to separate the grain According to different electrical grades, the crystal grains are picked from the wafer to the blue film of the same range (referred to as square wafers). [0003] The existing blue film grain sorting equipment generally adopts the swing arm vacuum suction method. During operation, the thimble below will lift up the grains to be placed (the thimble cover uses vacuum to suck the wafer blue film, and the thimble ejects from the middle The pinhole lifts the die from the wafer blue film), the swing arm w...

AI Technical Summary

Problems solved by technology

[0004] In view of this, the present invention aims at the deficiencies in the prior art, and its main purpose is to provide a fully automatic needle punching grain sorting equipment, which can effectively solve the problem of low working efficiency and inability of the existing blue film grain sorting equipment. Problems that meet production capacity requirements, cannot remove bad grains, and affect the quality of blue film
