The invention provides a battery module soldering clamp comprising a fixed plate, a first clamping mechanism and a second clamping mechanism. The first clamping mechanism comprises a first clamping plate, a second clamping plate, a first air cylinder and a second air cylinder, wherein the first clamping plate and the second clamping plate are opposite to each other; and the first air cylinder is used for driving the first clamping plate to move, the second air cylinder is used for driving the second clamping plate to move, and therefore the first clamping plate and the second clamping plate are made to cooperate with each other to clamp the two sides of a battery module. The second clamping mechanism comprises a first swing arm, a second swing arm, a third air cylinder and a fourth air cylinder, wherein the first swing arm and the second swing arm are opposite to each other; and the third air cylinder is used for driving the first swing arm to swing, the fourth air cylinder is used for driving the second swing arm to swing, and therefore the first swing arm and the second swing arm are made to cooperate with each other to clamp the two ends of the battery module. In this way, the battery module soldering clamp achieves automatic clamping and locating of the battery module, improves the production efficiency of the battery module and reduces the labor cost.
Description
technical field [0001] The invention relates to the technical field of lithium ion battery manufacturing, in particular to a battery module welding jig. Background technique [0002] With the development of the new energy vehicle industry, soft-pack lithium batteries are widely used. The production process of the soft-pack lithium battery module mainly includes: cell testing, cell insertion into the protective case, module cabin assembly, positive and negative electrode bronze plate assembly, positive and negative electrode laser welding, and module pole assembly. Among them, the welding process of the positive and negative electrodes of the battery module takes the longest time and belongs to the bottleneck link in the production process. [0003] In the prior art, when performing positive and negative laser welding, the battery module to be welded is manually transported to the workbench, and the battery module is manually positioned, and then the positioned battery modul...
