Description

Technical Field

[0001] The utility model relates to the technical field of photovoltaic component production devices, in particular to a mesh pressing tool used in photovoltaic components. Background Art

[0002] During the welding production process of the photovoltaic module string welding machine, a pressing tool is required to be placed on the welding strip. Each pressing pin in the pressing tool is pressed on the welding strip to fix the position of the welding strip so that the welding strip will not shift during welding. However, the placement and removal of the pressing tool is accompanied by the sliding of the pressing pin in the pressing pin hole. After the pressing tool is used for a long time, the pressing pin hole will be worn and the aperture will become larger. The pressing pin will shake in the enlarged pressing pin hole, thereby reducing the fixing stability of the welding strip. It is easy to cause the position of the welding strip to shift during welding, which in turn affects the welding quality of the module. Therefore, once the aperture of the pressing pin hole exceeds the specified size range, it will directly lead to the scrapping of the pressing tool. The cost of a pressing tool is about 1,500 yuan, which greatly increases the company's cost investment.

[0003] To this end, a mesh pressing tool for use in photovoltaic modules is proposed. Utility Model Content
