[0002] Cells are the main core components of solar panels, and their main function is to generate electricity. The mainstream on the market are crystalline silicon solar cells and thin-film solar cells, each of which has its own advantages and disadvantages. Crystalline silicon solar cells have relatively low equipment costs, but the consumption and cell costs are very high, but the photoelectric conversion efficiency is also high, and it is more suitable for generating electricity under outdoor sunlight; thin-film solar cells have relatively high equipment costs, but the consumption and battery costs are very low, but the photoelectric conversion efficiency is more than half of that of crystalline silicon cells, but the weak light effect is very good, and it can also generate electricity under ordinary lights, such as the solar cells on the calculator. A large number of cells are needed in the production process of solar panels, so the cells need to be cut. In order to cut the cells, people have designed a variety of cutting tools.

Due to the lack of a dust collection mechanism, the debris and dust will be scattered around the device, affecting the surrounding environmental hygiene and even people's health. Therefore, we need to propose a cutting device for crystalline silicon battery cells. Utility Model Content
