Description

Technical Field

[0001] The utility model relates to the technical field of photovoltaic solder ribbons, in particular to a positioning device for processing photovoltaic solder ribbons. Background Technique

[0002] Photovoltaic solder ribbons, also known as tinned copper strips or tin-coated copper strips, are divided into busbars and interconnection bars, which are used for connecting battery cells in photovoltaic modules and play an important role in conducting and collecting electricity. When processing and producing photovoltaic solder ribbons, it is necessary to wind the solder ribbons onto a solder ribbon reel. When winding the solder ribbons onto the solder ribbon reel, due to the different specifications of the reels, a positioning device is required to fix the solder ribbon reel and the rotating device, and then the solder ribbon reel rotates for winding.

[0003] During the process of winding the solder ribbons, after a certain amount of solder ribbons are wound onto the solder ribbon reel, a new solder ribbon reel needs to be replaced. However, the existing positioning devices generally use bolts for fixation, and the disassembly process is relatively complex when the positioning needs to be released to replace the reel, resulting in an extended working time and thus a low processing and production efficiency. Content of the Utility Model
