Erecting welding tool for soft package battery module

Abstract

The invention belongs to the technical field of electric car battery production and processing, and particularly relates to an erecting welding tool for a soft package battery module. The erecting welding tool for a soft package battery module comprises an overturn frame, a support and a base, wherein the overturn frame is rotationally arranged on the support along the horizontal axis, the support is installed on the base, a limiting device is arranged on the support, and the overturn frame can be locked to stay in the horizontal state or the vertical state by the limiting device. The overturn frame comprises a rectangular frame body and two end plates, wherein the rectangular frame body is formed by a bottom plate, two side plates and a top plate in an enclosure manner, each end plate is arranged at one end of the rectangular frame body, the distance between the top plate and the bottom plate is set to be adjustable, at least the end plate on one side is detachably connected with the rectangular frame body, a chamber for containing a battery module is formed inside the overturn frame, and notches for exposing the welding positions of the battery module are formed in each of the two end plates. With the erecting welding tool for a soft package battery module, the position of the battery module can be fixed, it is guaranteed that all the soft package batteries are aligned accurately, and meanwhile, the shell of the battery module can be tightly clamped, it is guaranteed the batteries inside the shell of the battery module are pressed tightly, and the accuracy of welding is guaranteed.

Description

technical field [0001] The invention belongs to the technical field of battery production and processing for electric vehicles, and specifically designs an assembly and welding tool for a pouch battery module. Background technique [0002] The battery module of an electric vehicle is generally composed of multiple battery cells connected in series. The battery cell can be a single battery cell or multiple battery cells connected in parallel. The soft pack battery is one of the battery cells. During the assembly process of the pack battery, firstly, multiple soft pack batteries must be glued, stacked neatly, and then welded and fixed by the battery module shell. In the prior art, the operator only manually stacks the soft white batteries together, which cannot ensure the precise alignment of the soft white batteries. At the same time, it is difficult to ensure that the shells are pressed tightly during the welding process, which affects the welding quality. Contents of the ...
