Silicon wafer detecting sorting machine and sorting method thereof

Abstract

The invention relates to a silicon wafer detecting sorting machine and a sorting method thereof. The machine comprises a rack, a work platform is mounted on the rack, a loading station, a detecting station and a classifying station are sequentially mounted on the work platform from left to right, a power conveying belt penetrating through the loading station, the detecting station and the classifying station in sequence is mounted in the middle of the work platform, the detecting station comprises a first camera obscura and a second camera obscura, cameras are mounted in the first camera obscura and the second camera obscura correspondingly, one camera lens faces downwards and is located above the power conveying belt, the other camera lens faces upwards, the height of the camera lens is lower than the height of the power conveying belt, a transfer mechanism moves silicon wafers to the power conveying belt from a material frame one by one, the camera in the first camera obscura carriesout front face detection, under assistance of a rotating disc mechanism, the camera in the second camera obscura carries out reverse detection, the silicon wafers with qualified appearance flow to the classifying station to be sorted to different color system material boxes along with the power conveying belt, dual-face appearance detection and color system classifying of the silicon wafers can be achieved, work efficiency is high, and silicon wafer sorting is greatly facilitated.

Description

technical field [0001] The invention relates to the technical field of photovoltaic auxiliary equipment, in particular to a silicon wafer detection and sorting machine and a sorting method thereof. Background technique [0002] With the increasing demand for high-quality solar cells in the industry, higher requirements are put forward for the quality of solar cells, including requirements for their appearance quality and color; sorted by quality and color. [0003] The sorting of silicon wafers involves the judgment of the double-sided appearance and color of each piece. Because the silicon wafers themselves are thin and fragile, it is difficult to sort and detect them. It is necessary to avoid damage to the silicon wafers. The operation is difficult and the cycle time is long. Work efficiency is low. Contents of the invention [0004] Aiming at the shortcomings of the above-mentioned existing production technology, the applicant provides a silicon wafer detection and so...
