Description

Technical Field

[0001] The utility model belongs to the technical field of photovoltaic component production equipment, and in particular relates to a bending device for photovoltaic components. Background Art

[0002] Photovoltaic welding ribbon, also known as tinned copper ribbon or tin-coated copper ribbon, is divided into busbar and interconnection strip. It is used to connect the solar cells of photovoltaic modules and plays an important role in conducting electricity.

[0003] In the process of connecting the cells of photovoltaic modules, bent photovoltaic welding ribbons are used. At present, the welding ribbons used in photovoltaic modules are manually bent and cut, and the cut welding ribbons are manually bent into shape. This is purely manual production, which has high labor costs. In the process of bending the welding ribbons, the welding ribbons are basically bent based on the personal experience of the operators. This not only leads to inconsistent bending angles of the welding ribbons for each cell, but also causes the welding ribbons to break when adjusting the bending angle, which is not conducive to the continued processing of the cell in the next process.
