[0002] At present, the new energy vehicle power battery industry is developing rapidly, various new energy vehicle models are constantly being introduced, and industries such as energy storage and battery replacement are also booming. Therefore, it is necessary to develop various modules, and the corresponding module tooling design also needs to be improved and innovated accordingly. In general, in the trial production of new modules or the production of small batches of module test pieces, simple tooling or even manual grouping of battery cells is often used in the industry. Although this grouping method can meet the requirements of short cycle and low cost in the design and development stage, the height of the battery cell pole and the consistency of the module size after the module are difficult to ensure, which affects the assembly of the subsequent process. In addition, the bus cannot completely fit the pole during welding, and the welding quality is difficult to ensure, and even the battery cell pole is welded through, leaving safety hazards. In short, the manual grouping method used in the early stage of trial production in terms of module grouping needs to be improved to overcome the problem of consistency of module size and battery cell height.
[0003] In order to meet the assembly quality requirements when such modules are grouped (in small batches), relevant battery manufacturers are in urgent need of designing a stable and reliable simple extrusion tooling. Utility Model Content

[0006] Furthermore, the workbench is composed of an aluminum profile bracket, a bracket base and a mold steel plate table top, and an antistatic insulating film with a thickness of 3 mm is provided on the workbench.
[0007] Furthermore, a fixed thrust pad is fixedly connected to the inner side of the fixed thrust baffle, and a sliding thrust pad is fixedly connected to the inner side of the sliding thrust baffle.
[0008] Furthermore, a tray self-locking mechanism is vertically installed on the side of the fixed thrust baffle. The tray self-locking mechanism is mainly composed of an L-shaped hook, a mechanism base and a return spring. The battery tray is hooked by the hook when it is close to the fixed thrust baffle, and the battery tray can be released by pressing the hook.
[0009] Furthermore, the fixed thrust pad and the sliding thrust pad are provided with magnets for adsorbing the module end plate onto the pads.
[0010] Furthermore, a battery cell tray limit block is provided at the right end of the slide rail.
[0011] Furthermore, the battery tray is provided with a plurality of bosses that cooperate with the battery poles, which play the role of lateral positioning of a single battery on the tray and maintaining the height of the battery poles.

When assembling the module, the single battery cell can be limited laterally and the height of the battery cell pole can be guaranteed to be consistent. During assembly, pressing the quick-pressing handle can press down the right end plate of the module. After adjusting the clamping stroke by sliding the joint on the thrust baffle, the module length can be guaranteed to be consistent, which greatly improves the module grouping quality. After installing the module bracket screws, loosen the self-locking device, and move the tray to the middle to easily remove the module. The anti-static insulating work surface reserved in front of the tooling can facilitate module flipping and subsequent operations. When using this simple tooling, if two people operate at the same time, the efficiency is relatively high, which can meet the tooling needs of the product in the small-batch trial production stage. The tooling is simple and practical, and can reduce the industrialization cost for the enterprise. BRIEF DESCRIPTION OF THE DRAWINGS
