Description

Technical Field

[0001] The utility model belongs to the technical field of battery module production and manufacturing, and specifically relates to an aluminum shell module stacking and pressing device. Background Art

[0002] As the core component of new energy vehicles, power battery packs are the focus of people's attention and are closely related to the use of new energy vehicles. Power battery packs are mainly composed of modules, battery management systems and other electrical mechanical devices. The size of the modules of the power battery pack directly affects the size of the remaining space inside the power battery pack and the subsequent assembly of the power battery pack. In addition, the size of the preload force of the module will directly affect the structural stability and cycle life of the power battery pack. Therefore, during the production process of the power battery pack, the length of the module and the preload force during the module molding need to be strictly controlled. During the production process of the module, the battery, end plate and side plate need to be assembled and welded. The packaging and tightening of the end plate and the battery stacking directly affect the module length and the preload force during molding. The packaging and tightening of the end plate and the battery stacking generally use simple tooling to stack the batteries. The stacked batteries are placed on the mechanical positioning mechanism, and the mechanical tightening handle of the mechanical positioning mechanism is rotated to limit the length of the module, and then the module is packaged and tightened. The packaging and tightening of the modules cannot be carried out in a continuous manner, resulting in low production efficiency. During the stacking and molding process, the accuracy of the pressing stroke and pre-tightening force control is poor, and the consistency of the module length and the pre-tightening force during molding cannot be guaranteed during the module stacking process, which can easily lead to poor module length and affect the subsequent assembly and cycle life of the power battery pack.
