[0002] Lithium battery rubber coating can effectively improve the safety and durability of the battery, and the rubber coating process is an important process in the production process of lithium batteries, which can prevent the battery structure from loosening. In the production process of large cylindrical lithium batteries, the winding core and the positive current collector are welded, and then the winding core positive terminal is rubber coated to prevent the positive current collector from contacting the inner wall of the steel shell.

[0003] The existing rubber coating equipment uses a battery transverse movement method, moves to the rubber coating station, and performs rolling rubber coating.

[0004] 1. The rolling rubber coating has high requirements for the diameter of the winding core. The rolling rubber coating uses a winding core transverse placement method. If the winding core diameter is too small, the winding core may not rotate smoothly and may be stuck, causing the winding core to be poorly or unsuccessfully rubber coated, affecting the entire process.

[0005] 2. The rolling rubber coating winding core transverse placement method has support rollers at both ends of the winding core, and a driving roller above the winding core. The driving roller rotates to drive the winding core to rotate. If the winding core diameter is too large, the winding core is unevenly stressed, and dark marks may appear on the surface of the pole piece, affecting the performance of the battery.
