Abstract

The invention discloses a lithium ion battery pole piece winding device, which comprises a fixing seat, wherein one side of the outer wall of the top of the fixing seat is fixedly connected with a mounting plate, the outer wall of one side of the mounting plate is provided with a winding mechanism, one side of the outer wall of the top of the fixing seat is fixedly connected with a supporting frame, a connecting plate is rotationally connected between the outer walls of the two opposite sides of the supporting frame through bearings, two supporting rods are fixedly connected to one side of the outer wall of the top of the fixing base, a balance plate is rotationally connected between the outer walls of the opposite sides of the two supporting rods through bearings, and one side of the top outer wall of the balance plate is connected with one side of the bottom outer wall of the connecting plate through a hinge. According to the invention, the phenomenon that the battery pole piece is bent due to insufficient tension of the battery pole piece and the phenomenon that the battery pole piece is broken due to the fact that the battery pole piece is in a tight state for a long time can be prevented, dust adhered to the battery pole piece can be treated, and dust is prevented from adhering to the surface of the battery pole piece to corrode the battery pole piece.

Description

technical field [0001] The invention relates to the technical field of lithium-ion battery pole pieces, in particular to a lithium-ion battery pole piece winding device. Background technique [0002] Lithium-ion battery is a secondary battery (rechargeable battery), which mainly relies on lithium ions to move between the positive electrode and the negative electrode to work. During the charging and discharging process, Li+ intercalates and deintercalates between the two electrodes: , Li+ is deintercalated from the positive electrode, inserted into the negative electrode through the electrolyte, and the negative electrode is in a lithium-rich state; the opposite is true when discharging. With the rapid development of economy and technology, lithium-ion batteries have been used in various industries in recent years, and lithium-ion batteries in the production process In the process, the electrode sheet needs to be wound by a winding device. [0003] When the existing device i...
