Problems solved by technology

This process is cumbersome, consumes a lot of labor, and the production efficiency is low. In addition, the separator is easily pierced by the pole plate when the battery pole group is assembled, which greatly increases the short circuit probability of the pole group and increases the failure rate of the product.

Abstract

The invention discloses a battery pole group welding device. The battery pole group welding device comprises a base, a battery pole group clamping mechanism and a pneumatic compressing mechanism, wherein the battery pole group clamping mechanism and the pneumatic compressing mechanism are in driving connection. The battery pole group welding device further comprises a mold box base plate which is arranged on the base, wherein the battery pole group clamping mechanism is arranged on the mold box base plate and comprises a movable side plate group and a fixed side plate group. The invention further discloses a battery pole group welding method. According to the device and the method, a first movable side plate, a second movable side plate, a first fixed side plate and a second fixed side plate which are connected with the pneumatic compressing mechanism are arranged, the first movable side plate is pushed by the pneumatic compressing mechanism, the second movable side plate is driven by the first movable side plate through a first connecting rod, and battery poles and separation plates, which are placed between the movable side plate group and the fixed side plate group are simultaneously compressed, so that the aim that whole groups of battery poles are welded together can be realized.

Description

technical field [0001] The present application relates to the field of battery production equipment, in particular to a battery electrode group welding device and welding method. Background technique [0002] In the prior art, the general process for welding battery pole groups is as follows: weld butt weldments, poles, etc. on a single pole group, and then combine multiple pole groups. Separators are added between the groups, and finally the entire battery electrode group is packed into the battery case. This process is cumbersome, consumes a lot of labor, and the production efficiency is low. In addition, the separator is easily pierced by the pole plate when the battery pole group is assembled, which greatly increases the probability of short circuit of the pole group and increases the failure rate of the product. Contents of the invention [0003] The technical problem to be solved in this application is to provide a battery electrode group welding device and welding ...
