Problems solved by technology

There is a separation between the various production steps, resulting in a significant increase in logistics costs and storage fees. In terms of output, there are wastes in the early stage of starting up every time the copper flat strip wool is processed, and the production efficiency and product quality are not high. , and in the repeated closing process, a certain tension will be applied to the copper strip, which greatly reduces the yield strength of the copper strip

Description

technical field [0001] The invention relates to a production process of a special copper flat belt for photovoltaic welding and converging belts, in particular to a production process for a special copper flat belt for photovoltaic welding and converging belts. Background technique [0002] At present, there are many kinds of production processes in the photovoltaic ribbon manufacturing industry, but generally speaking, there are two main types of copper flat ribbon forming processes for photovoltaic ribbon confluence belts: slitting and copper wire pressing. [0003] The production process of copper wire pressing and processing photovoltaic ribbon includes main steps such as calendering, drawing, and annealing. According to specific processing conditions and processing requirements, it also includes pre-drawing of copper wire, multiple calendering, and baking after annealing. Dry, the final closing and other steps. At present, for the production and processing of copper fla...
