Description

Technical Field

[0001] The utility model relates to the technical field of solar photovoltaic component production, in particular to a tin-coated soldering strip production device for solar photovoltaic components. Background Art

[0002] The welding ribbon is an important raw material in the welding process of photovoltaic modules. The quality of the welding ribbon will directly affect the current collection efficiency of the photovoltaic module and have a great impact on the power of the photovoltaic module.

[0003] In the prior art, in the production process of tin-coated solder strips, the tin material is generally heated and melted to coat the photovoltaic solder strips with tin. After tin coating, dripping is easily generated, resulting in uneven thickness of the tin coating layer, wasting tin material resources. In addition, the production process of tin-coated solder strips generally uses copper strips to slit round copper wires to produce flat copper strips, which are then tin-coated. The slit copper strips need to be rolled and then unrolled when tinning, which prolongs the production time of tin coating and reduces the efficiency of tin coating.

[0004] In view of this, the present utility model is proposed. Utility Model Content
