All-tab battery roll core kneading device and kneading method

Abstract

The embodiment of the invention provides an all-tab battery roll core kneading device and a kneading method. The all-tab battery roll core kneading device comprises a battery clamping device and a kneading device. The kneading device can move along the direction close to or far away from the battery clamping device. A kneading head assembly is mounted on the kneading device. The kneading head assembly can feed along the radial direction parallel to the pre-kneading end surface of the full-tab battery roll core. The battery clamping device and the kneading device can rotate relatively, so that the kneading head assembly can press tabs on a full-tab battery roll core one by one from outside to inside. The kneading head assembly on the kneading device can press tabs on the full-tab battery roll core one by one from outside to inside along the radial direction of the pre-kneading end surface. Therefore, the pressing directions of the tabs of the roll core of the full-tab battery are consistent, the contact effect between the tabs is ensured, and the current collection effect of the full-tab battery is further improved. According to the kneading device, the tabs cannot be shattered, and the safety of the full-tab battery is greatly improved.

Description

technical field

[0001] The invention relates to the technical field of battery processing, in particular to a flattening device and a flattening method for an all-tab battery core. Background technique

[0002] In the production process of the all-tab battery, a tab rubbing process is required. The tab rubbing process is to overwhelm the originally upright tabs so that the tabs are in contact with each other for better current collection. At the same time, the tabs after kneading are in the same plane, which is also convenient for the subsequent welding work of the collector plate.

[0003] At present, there are mainly two methods of kneading and flattening the ear, mechanical kneading and ultrasonic kneading. Among them, most of the existing mechanical kneading methods are to knead the tabs by axial feeding. This method will lead to inconsistencies in the direction of the overwhelm of the tabs, deformation of the tabs, and affect the contact effect of each tab, thereby r...
