Technical Problem
[0003]目前二次电池的电芯在卷绕时基本上都是使用圆形卷针进行高速卷绕并夹持抽针下料，这个过程受限于成型机构(卷针)的支撑，卷制品的内侧隔膜不会发生形变，待卷绕完成后卷制品与卷针分离时，卷制品的内侧隔膜失去卷针的支撑而不受控制，且压合卷制品生成电芯时，芯部隔膜整体会发生形变，该形变极易导致卷制品内部隔膜起皱等情况，进而导致卷制品品质降低，影响电池的安全性能
Benefits of technology
[0033] 1. This invention, by setting a smoothing mechanism and using a paddle-like method to smooth the uncontrolled core diaphragm of the rolled product according to the actual situation of the rolled product, and finally attaches it to the inner surface of the rolled product, can effectively solve the problem of wrinkling of the uncontrolled part of the inner diaphragm of the battery cell, effectively improve the safety performance of the battery cell, and has a simpler structure and stronger practicality compared with the prior art.

Abstract
The present application relates to the technical field of battery production, and provides a dial piece type winding product clamping device, which comprises a support, a lifting mechanism arranged on the support, and clamping mechanisms and flattening mechanisms respectively arranged on the lifting mechanism and capable of adjusting the vertical direction height thereof under the driving of the lifting mechanism, wherein the flattening rods of the flattening mechanisms are used for dialing the core separator on the inner side of the flattened winding product, so that the core separator can be attached to the inner side surface of the winding product. According to the present application, the flattening mechanism is arranged, and the flattening mechanism is driven to move according to the actual situation of winding, so that the uncontrollable core separator can be flattened and finally attached to the inner side surface of the winding product, the problem of uncontrollable wrinkling of the core separator of the battery cell can be effectively avoided, the safety performance of the battery cell is effectively improved, and the structure is simpler than that of the prior art.
