Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of lithium battery manufacturing, and more specifically, to a flat push roller mechanism. Background Art
[0002] In recent years, with the development of science and technology, lithium batteries have become the most critical energy supply components in the fields of wireless communication equipment, electric vehicles, aircraft, and aerospace equipment due to their advantages such as high energy density and no memory effect. Their production process and product quality have an increasing impact on these industries. Among them, a key step in the production process of lithium batteries is the substrate coating and winding process.
[0003] However, in the existing lithium battery production process, a fixed winding mechanism is used, and its working principle is mainly driven by a motor, then transmitted through a sprocket, and finally driven by a chuck to rotate the reel to complete the winding of the substrate. Although this method greatly improves production efficiency, due to the design and operation of its winding mechanism, the substrate will inevitably produce horizontal or vertical wrinkles during the winding process. The generation of wrinkles is closely related to factors such as uneven thickness of the substrate itself, uneven crystallization of the coating slurry, and excessive tension during winding. Under the existing winding system, since it is impossible to effectively adjust the tension and thickness during the winding process in real time, these factors are difficult to be effectively controlled during the winding process. Once wrinkles are generated, wrinkles that are difficult to eliminate will be formed on the entire roll of substrate without external intervention. This wrinkle has a great impact on the performance of the substrate. It can be said that once there are serious wrinkles on the surface of the substrate, this part of the substrate is basically unusable and needs to be scrapped. This will result in a large amount of substrate waste, causing great damage to production costs. Utility Model Content
