Abstract
Description
Technical Field
[0001] This utility model belongs to the field of current collector technology, specifically relating to a winding device for current collector production. Background Technology
[0002] A current collector, as the name suggests, refers to a structure or component that collects current. In lithium-ion batteries, it mainly refers to metal foil, such as copper foil or aluminum foil. More broadly, it can also include the tabs. Their main function is to collect the current generated by the battery's active materials to form a larger current output. Therefore, the current collector should have sufficient contact with the active materials, and its internal resistance should be as low as possible.
[0003] During production, the current collector needs to be wound onto a paper roll. However, conventional winding devices cannot properly clamp and fix the current collector, causing it to become loose and affecting the winding effect. Furthermore, the clamping width is fixed and cannot be adjusted, thus affecting the performance. Utility Model Content

A crank handle is connected to one end of the threaded sleeve, and a threaded inner rod is threadedly connected inside the threaded sleeve. A limiting arc block is connected to one end of the threaded inner rod, and a limiting inner rod is provided at one end of the limiting arc block.
