[0002] As an essential piece of equipment in photovoltaic cell string production, the series connection machine's main function is to connect multiple cells together via welding strips to form a cell string. During the production process, the welding strip tail clamp assembly on one side of the welding belt needs to clamp or release the welding strip. The existing welding strip tail clamp assembly operates on the following principle: the left and right jaws are driven by corresponding cylinders; guide wheels engage with oblong holes on the base plates of the left and right jaws, and wear-resistant plates press the jaws together, causing them to move only in the X-direction, thus achieving the function of clamping the product. However, in the existing cell string welding process, the difference in the intake and exhaust times of compressed gas in the left and right cylinders affects the clamping accuracy of the welding strip. Therefore, a welding strip tail clamp mechanism and series connection machine are provided to solve this problem. Utility Model Content
