Pole piece winding equipment for lithium battery manufacturing

Abstract

The invention discloses pole piece winding equipment for lithium battery manufacturing. The equipment comprises a base, wherein two supporting plates are fixedly arranged on the two sides of the top end of the base correspondingly, the bottoms of the two supporting plates are connected with the two ends of a first rotating shaft in an inserted mode through bearings correspondingly, sliding groovesare formed in the tops of the two supporting plates correspondingly, two sliding blocks are slidably arranged in the two sliding grooves correspondingly, the middles of the two sliding blocks are connected with the two ends of a second rotating shaft in an inserted mode through bearings correspondingly, and the top ends of the two sliding blocks are fixedly connected with the top ends of the inner walls of the two sliding grooves through two first springs correspondingly. According to the pole piece winding equipment for lithium battery manufacturing, a pole piece can be pressed to be flattened through a pressing roller in the winding process, wrinkles are avoided, and meanwhile, the position of the pressing roller can be changed along with the change of the thickness of a pole piece rollthrough the first springs, so that the pressing roller can continuously play a pressing flattening role, the winding efficiency is improved, manual pressing flattening is avoided, and the safety of workers is guaranteed.

Description

technical field [0001] The invention relates to a winding device, in particular to a pole piece winding device used for manufacturing lithium batteries. Background technique [0002] Lithium battery is a primary battery that uses lithium metal or lithium alloy as the negative electrode material and uses a non-aqueous electrolyte solution. It is different from rechargeable batteries. Lithium-ion batteries are different from lithium-ion polymer batteries. Lithium battery electrodes are produced and processed Rewinding is required in the process, and then rewinding equipment is required. [0003] At present, due to the low strength of the positive electrode sheet of the lithium battery, the electrode sheet is prone to wrinkles during the winding process. The existing winding equipment needs to manually flatten the electrode sheet during the winding process, which affects the winding efficiency. The safety of the staff is endangered, and the existing winding equipment cannot co...
