Description

Technical Field

[0001] The utility model relates to the technical field related to photovoltaic welding tape processing, and in particular to a photovoltaic welding tape collecting device. Background Art

[0002] The welding ribbon is a welding material used on photovoltaic modules. Its main function is to connect and conduct electricity. 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] After massive searches, it was found that the prior art publication number is CN215557734U, which discloses a winding device for resistance welding strips, including a base plate, a stretching mechanism fixedly installed on the base plate, a winding mechanism fixedly connected to one side of the stretching mechanism, and a driving motor fixedly connected to the base plate. The welding strip is placed between the first pressure roller and the second pressure roller, and the welding strip is driven by the first rotating shaft and the second rotating shaft to advance in the first pressure roller and the second pressure roller, thereby improving the flatness of the welding strip and protecting the welding strip from being pulled and broken during the later winding process. Then the welding strip reaches the winding drum position, and the first rotating rod connected to the first turntable is driven to rotate through the rotating shaft of the hand crank, and the rotating rod drives the winding drum to rotate at the same time, so as to achieve the function of winding the welding strip. The force of the hand crank can be buffered by the spring to prevent excessive force and excessive speed of the winding drum from causing the welding strip to break, and to prevent the side of the welding strip from being deformed and wrinkled during the winding process.

[0004] To summarize, when the existing soldering strip is being wound, the distance between the unwinding roller and the winding roller is generally not fixed. When the distance is long, the soldering strip needs to be guided and supported. In addition, when the winding roller is winding the soldering strip, there is no limiting structure on both sides of the winding roller, which may cause problems such as soldering strip deviation.

[0005] In view of the above-mentioned defects, the designer actively carried out research and innovation in order to create a photovoltaic welding tape collecting device to make it more valuable for industrial use. Utility Model Content
