Abstract

The invention relates to electrode sheet winding equipment, which comprises: an electrode sheet unwinding device used for driving a material roll to output an electrode sheet to a material receiving position; an electrode sheet feeding device arranged at the downstream of the electrode sheet unwinding device, wherein the electrode sheet feeding device comprises an electrode sheet clamping assemblyand a driving assembly, the electrode sheet clamping assembly is connected with the driving assembly, and the electrode sheet feeding device can clamp the roll-in section of the electrode sheet at the material receiving position through the electrode sheet clamping assembly; and drives the electrode sheet clamping assembly to reciprocate between the material receiving position and the material feeding position through the driving assembly; and an electrode sheet winding device arranged at the downstream of the electrode sheet feeding device, wherein the electrode sheet winding device comprises a winding needle for winding the electrode sheet, and at the feeding position, the electrode sheet feeding device can directly convey the roll-in section to the winding needle. According to the electrode sheet winding equipment, it can be guaranteed that the roll-in section of the electrode sheet has controllable tension force, and the possibility that the roll-in section is prone to displacement, bending, folding and the like when entering a winding needle is reduced.

Description

technical field [0001] The invention relates to the technical field of battery processing equipment, in particular to a pole piece winding equipment. Background technique [0002] In the production process of power lithium batteries, it is necessary to use winding equipment to wind the pole pieces into batteries. In the initial step of winding, the winding needle pre-winds a certain number of layers of inner and outer separators, and then sends the pole piece to the winding needle, and finally makes the pole piece and the separator be wound by the winding needle. However, in the winding process of the prior art, the winding-in section of the pole piece (which can be the initial section or the end section of the pole piece to enter the winding needle) will be in free suspension before it completely enters the winding needle. As a result, there is no tension in the winding section of the pole piece, so the winding section of the pole piece is easy to shift and deviate, result...
