Description

Technical Field

[0001] The utility model relates to the technical field of photovoltaic component processing and production, in particular to a positioning component of a string welding mould for a solar panel string welding machine. Background Art

[0002] Photovoltaic cells are usually connected by welding. Specifically, the cells are welded by an automatic stringing machine. During the welding process, the interconnection strip (the welding strip used to string photovoltaic cells together) contacts the electrode area of ​​the cell after a positioning step, and a press is used to make the interconnection strip fit tightly to the electrode surface. It then enters the heating light box. Under the action of an external heat source, the interconnection strip and the cell electrode are welded into shape. The main function of the press is to maintain a good contact state between the solar panel cell and the pad, ensuring a good connection between the pad and the solder.

[0003] In the prior art, the tooling of the string welding machine is generally an integrated welding pin pressing mold, and the pin pressing mold is suspended as a whole above the welding strip. When the front of the battery cell is welded, the heat radiated by the infrared lamp tube is absorbed by the pin pressing mold, and only the part of the welding strip in contact with the pin can quickly transfer the heat to the welding strip, so that the welding strip at this position quickly melts and welds.

[0004] However, due to different battery specifications, the width of the main grid lines on the battery cells is inconsistent, and the position of the pin row in the pin pressing mold is fixed and cannot be adjusted. During use, the entire row needs to be replaced and disassembled. Frequent replacement leads to low production efficiency of the battery panels. Utility Model Content

[0026] The purpose of setting the fixing plate 5 is to enable the pressing plate strip 1 to slide in the needle pressing mold 2 for position adjustment. The plug-in plate 11 is plugged into the fixing plate 5 to fix the fixing plate and the needle pressing mold 2.

[0027] Embodiment 3

[0028] See also Figures 4 to 5On the basis of the second embodiment, in order to realize that the pressure plate strip 1 can be fixed on the surface of the needle pressing mold 2, the plug-in plate 11 has a cylindrical structure, and the surface of the plug-in plate 11 is rotatably connected with a handle 10, and the handle 10 is buckled in the handle groove 9 opened on the surface of the fixed plate 5.
