[0002] With the continuous development of battery technology, pole pieces, as an important part of the battery, have a vital impact on the overall performance of the battery. In the battery manufacturing process, the roller press, as a key equipment for pole piece processing, is mainly responsible for rolling the pole pieces to improve their physical properties and structure; the rolling process not only affects the density, thickness and flatness of the pole pieces, but is also directly related to the energy density, cycle life and safety of the battery; therefore, how to ensure the stability and quality consistency of the pole pieces during the rolling process has always been the focus of attention in the industry.
[0003] In the prior art, when processing pole pieces, roller presses in the industry usually attach Teflon material to the passing roller or tension roller in order to prevent the pole pieces from having wavy edges and pole ear wrinkles. Teflon is used to adjust the force balance of the collector in the coating area and the empty foil area during the rolling process due to its good physical properties. However, when the position of the pole piece or the coating area changes, the Teflon needs to be replaced or reattached to adapt to the new requirements. This process not only increases the complexity of the rolling process, but also increases the manufacturing cost. Each replacement involves equipment shutdown, which affects production efficiency, so it needs to be improved. Utility Model Content
