High-precision self-adaption battery module welding fixture

Abstract

The invention relates to the technical field of battery module production equipment, in particular to a high-precision self-adaption battery module welding fixture. The high-precision self-adaption battery module welding fixture comprises a platen for bearing an outer battery module, a first hold-down mechanism, a second hold-down mechanism pressing an outer long side plate to the long side face of the battery module in an attaching manner, a third hold-down mechanism pressing an outer short side plate to the short side face of the battery module in an attaching manner and a fourth hold-down mechanism used for carrying out fine adjustment on the long side plate. The first hold-down mechanism is used for abutting against the top of the battery module, the top of the outer long side plate and the top of the outer short side plate and is hinged to the platen. The second hold-down mechanism and the third hold-down mechanism are both connected to the platen in a sliding manner. The platen is provided with the second hold-down mechanism and the third hold-down mechanism, so that position pre-fixation of the battery module, the long side plate and the short side plate is achieved; and dueto the fact that the first hold-down mechanism presses the top of the battery module, the top of the long side plate and the top of the short side plate, the position fixation of the battery module,the long side plate and the short side plate is finally completed, and the production machining yield is increased.

Description

technical field [0001] The invention relates to the technical field of battery module production equipment, in particular to a high-precision self-adaptive battery module welding fixture. Background technique [0002] In the aluminum shell battery module manufacturing industry, a laser welding process is required in the assembly process of the aluminum shell battery module. After welding the end plates and side plates in the aluminum shell battery module assembly, the next step is performed. . However, if the relative position of the battery module, side panel and end panel cannot be accurately positioned before laser welding, it will directly affect the welding quality of the battery module, such as the problems of virtual welding, missing welding, welding deviation and welding seam depression. As a result, the overall size of the battery module is deviated, or the internal pressure of the battery module is uneven, and the production quality of the battery module is unstab...
