Description

Technical Field

[0001] The utility model belongs to the technical field of busbars, and more specifically relates to a busbar forming and handling assembly for a photovoltaic assembly. Background Art

[0002] In the production of photovoltaic silicon cells, several relatively small unit cells are first arranged into cell strings, and then several cell strings are arranged in columns to form rectangular sheets, thereby producing larger solar panels.

[0003] The battery strings need to be welded through bus bars. The existing bus bar forming and handling device needs to load and cut all the bus bars required for welding, and the battery string layout is not single-string step-by-step. The bus bars need to be uniformly transported to the welding site for welding. In this process, it is necessary to wait for the bus bars to be processed one by one. When welding the battery string, it is necessary to wait for the bus bars to be transported. Only after all the bus bars are transported can the battery string be welded. The cut bus bars cannot be immediately sent to the battery string for welding. The bus bar forming journey time is long, which will take up more time, thereby delaying the production efficiency of the entire processing flow. Summary of the invention

[0004] The technical problem to be solved by the utility model is to provide a busbar forming and handling assembly for a photovoltaic module, which can reduce the cutting and forming stroke of the busbar. The cut busbar can be immediately transported and transferred without waiting for all the busbars to be cut.
