Description

Technical Field

[0001] The utility model relates to the technical field of welding strip processing, in particular to a tinning device for processing triangular welding strips. Background Art

[0002] Photovoltaic welding ribbons are divided into busbars and interconnecting strips, which are used to connect the cells in photovoltaic modules. Photovoltaic welding ribbons are important raw materials in the welding process of photovoltaic modules. The quality of photovoltaic welding ribbons directly affects the current collection efficiency of photovoltaic modules and has a great impact on the power of photovoltaic modules.

[0003] The production process of photovoltaic welding ribbons usually includes important steps such as rolling, annealing, flux coating, and tin coating. The uniformity of tin coating has a greater impact on the quality of photovoltaic welding ribbons. At present, photovoltaic welding ribbons usually use triangular welding ribbons, which are divided into flat sections and triangular sections. The two inclined surfaces of the triangular sections can reflect more sunlight onto the cells of the photovoltaic modules to increase the conversion efficiency of the photovoltaic modules.

[0004] During the production process of triangular welding strips, they need to be tinned. However, the existing equipment is prone to incomplete coating during the tinning process, and after the coating is completed, it is necessary to continue pulling to dry it. Therefore, it is necessary to increase the drying process, which may cause deformation or winding creases during the repeated pulling and retracting process. For this reason, we propose a tinning device for triangular welding strip processing. Utility Model Content
