Abstract

The invention relates to a main grid-free solar cell piece welding device. The main grid-free solar cell piece welding device comprises a welding net welding device for welding welding wires into a welding net, a cell piece welding machine for welding the welding net and main grid-free solar cell pieces into a solar cell piece panel, a solar cell piece feeding device for conveying the solar cell pieces to the cell piece welding machine, and a welding net feeding device for conveying the welding net formed by the welding net welding device to the main grid-free solar cell pieces on the cell piece welding machine. The pre-woven welding net is adopted, and then the whole welding net is spread and welded, so that the welding efficiency of the cell pieces is improved, the exposure of the cell pieces is reduced, the welding quality of the cell pieces is better ensured, and the conversion efficiency of the cell pieces is improved.

Description

technical field [0001] The invention belongs to the technical field of automatic manufacturing equipment, and in particular relates to a busbar-free solar cell sheet welding device. Background technique [0002] Solar energy is a new type of energy that is non-polluting, non-regional, and inexhaustible. Using solar energy to generate electricity has become a major trend, and how to improve the conversion efficiency of battery cell components has also become the main direction of solar energy development. At present, there is a busbar-free anti-crack battery pack in the industry (such as a utility model patent for a busbar-free anti-crack battery component, application number 201620971285.8), which has low component loss and anti-crack compared with traditional battery packs. Advantages such as hidden cracks will become a development trend of solar modules in the future. Because of this kind of battery sheet group, a new welding process needs to be adopted, but the stringer ...
