Laser equipment for splitting battery pieces

Abstract

The invention provides laser equipment for splitting battery pieces. The laser equipment is easy to use and adjust, and damage to the battery pieces can be reduced. The laser equipment comprises a laser unit and a base. A lifting column is arranged on the base, a laser cover is mounted on the lifting column in an up-and-down sliding manner, the laser unit is arranged in the laser cover, a speed expander assembly connected with the laser unit is arranged in the laser cover in the laser beam emitting direction of the laser unit, the end of the speed expander assembly is connected with a pinboard, the pinboard is connected with a galvanometer cover, light outlets are formed in the pinboard and the galvanometer cover, the light outlets are horizontally flush with a laser beam output port of the laser unit, and a galvanometer assembly is arranged in the galvanometer cover in order to enable laser beams to be deflected on the battery pieces put below the galvanometer cover.

Description

technical field [0001] The invention relates to the technical field of laser equipment, in particular to a laser equipment for splitting battery slices. Background technique [0002] With the advancement of photovoltaic technology and the in-depth advancement of the "Top Runner" program, China's photovoltaic industry has entered an era of high-efficiency product competition. As one of the mainstream high-efficiency module technologies, the shingling technology is currently receiving widespread attention. The shingling module mainly uses the slicing technology to cut the grid-line redesigned cells into small pieces with reasonable graphics, stack and arrange each small piece, and weld them into strings. , and then laminated into modules after series-parallel typesetting, so that the cells are connected to each other in a more compact way. Under the same area, the shingled module can place more than 13% of the cells of the conventional module, which is more efficient and lower...

AI Technical Summary

Problems solved by technology

[0003] At present, the cutting and splitting process of the cell is to first use laser cutting, which mainly uses the laser to scratch the surface of the material, but the cell is still intact and has not been separated, and then uses a mechanical breaking mechanism to pull the material (or there is Bending) to break the material, but the structure of the mechanical breaking sheet is complex, the steps to use are cumbersome, and it is difficult to adjust. Once the adjustment is not good, the cells will be scrapped in batches
