Description
Technical Field

[0002] Photovoltaic welding ribbon, also known as tinned flat copper wire or tin-coated flat copper wire, is divided into busbars and interconnecting strips. It is used to connect the cells of photovoltaic modules and plays an important role in conducting electricity. The production of photovoltaic welding ribbon includes two processes: rolling and tinning. First, the round copper wire of a certain wire diameter is rolled into a flat copper wire through a rolling wheel, and then tinned. In the tinning stage, the coating thickness accuracy of the tin on the flat copper wire is required to be ±0.05mm, so that the busbars and interconnecting strips produced can meet the welding requirements of solar panels.
[0003] At present, the conventional process flow of the existing tin-plating coating section is: the rolled and annealed flat copper strip is passed through a tin tank containing completely dissolved liquid tin so that its surface is covered with liquid tin, and then it is extracted; the excess tin is scraped back into the liquid tin tank through wind knife shaping; after wind knife shaping, the tin attached to the copper strip is immediately cooled and solidified rapidly, and the tin-plated copper strip reaches the required size standards.
[0004] In the above scheme, the existing wind knife position cannot be adjusted to place the flat copper strip in the middle of the two wind knives, resulting in unbalanced wind force on the flat copper strip during the production process, which is prone to shaking, resulting in poor thickness uniformity of the tin plating layer; at the same time, it is inconvenient to adjust the air outlet angle of the wind knife, and the adjusted wind knife cannot be locked well, resulting in vibration when the wind knife blows out the air flow, further resulting in poor thickness uniformity of the tin plating layer.
