Illumination Sorting Station for Small Defects of Solar Cells

Abstract

A light sorting table for small defects of solar cells, including a smooth transparent glass plate, a frame-shaped tray, a lighting lamp and a desk, the frame-shaped tray is fixed on the desktop of the desk, and the lighting is fixed on the desk It is placed on the desktop of the desk, and is located in the frame-shaped tray. The smooth and transparent glass plate is placed above the frame-shaped tray, and there is a defective product box on the right side of the desk; using a smooth and transparent glass plate as the surface of the battery sheet on the table will not Scratches are generated; since the lighting lamp is installed on the desktop, the defects existing on the sheet-shaped battery sheet can be clearly displayed under the illumination of the lighting lamp, which is more convenient for naked eye observation and judgment, thus improving the accuracy of naked eye judgment The efficiency; the addition of a defective product box on the right side of the smooth and transparent glass plate can immediately separate the detected defective products from the genuine products, preventing the defective products from being confused with the genuine products on the table.

Description

Technical field: [0001] The invention relates to a detection device for solar cells, in particular to a sorting workbench for solar cells. Background technique: [0002] In the production process of solar cells, although most of the processes are completed by automatic assembly line equipment, defects such as color difference, poor printing, small cracks, and partial missing corners of cells cannot be fully identified on automatic assembly line equipment. Therefore, After mechanical sorting, it is necessary to manually sort again to pick out defective cells. Currently, the sorting stations used are figure 1 As shown, it is a wooden desk structure, including a desktop board 41, an open drawer 42 and a support frame 43, the desktop board 41 is horizontally installed on the support frame 43, and two open drawers 42 are arranged below the desktop board 41, and the desktop board 41 It is a wooden board with a relatively rough surface. This kind of sorting table has the followin...

AI Technical Summary

Problems solved by technology

[0003] ①The desktop board is rough, and the surface of the cell is prone to scratches during sorting and movement

[0004] ②The desktop board is opaque, and the light is not enough during sorting. It is difficult to see all the defects of the cells with the naked eye, and the cells to be sorted cannot be sorted thoroughly.

[0005] ③Due to the limited area of ​​the desktop board, both the defective product and the original product are placed on the desktop board, and the two are easily confused

[0006] ④Rough desktop boards can cause scratches on the surface of the solar cells. Defective cells are not easy to be found, and the rate of missed inspections is high.
