Description

Technical Field

[0001] The utility model relates to the technical field of module assembly into a box, in particular to a CTP module box - loading device. Background Technique

[0002] With the fierce competition in the current new - energy vehicle industry, the core competitiveness of electric vehicles has shifted to cost competition. With the reduction of the cost of battery cells, there is also a strong demand for cost reduction in the battery system other than the battery cells, namely long endurance and high energy density.

[0003] At present, the new - energy vehicle industry is committed to improving the energy density of power battery systems to meet the trends of vehicle lightweight and long endurance of new - energy vehicles. For various reasons, mainstream power battery manufacturers in China have adopted the module - less technology, that is, CTP technology (Cell To Pack); for CTP module box - loading, since there is no traditional module frame and the module is closely attached to the box wall when being boxed, it is necessary to pre - squeeze the module to the box - loading size and box it in a compressed state. The current CTP module box - loading device uses jaw extrusion for box - loading. When box - loading, the jaws are in hard contact with the module end plate, with large friction, which poses a risk of scratching the module, or it cannot be fully boxed due to excessive friction, resulting in poor consistency of the modules after being boxed, and having disadvantages such as low box - loading qualification rate, complex process, and high requirements for manual operation. Content of the Utility Model

When the extrusion cylinder 401 pushes the module into the box in the vertical direction, the belt rollers 4033 and the wide belt 4035 can roll as the module descends, so that the module is not affected by friction when entering the box, thereby preventing friction damage to the side plate of the module. The belt support plate 4034 plays a role in fixing and supporting the belt, ensuring that the rolling claw assembly 403 can completely clamp the lithium battery module and press it to the size for putting it into the box.

[0037] In use, the manually stacked modules are placed on the transfer trolley 500 and transferred to the lower part of the hoisting mechanism 200 of the device. The lifting cylinder 204 drives the suction cup 208 to move along the Z-axis to the transfer trolley 500, presses the suction cup 208 onto the surface of the module, sucks up the lithium battery module from the transfer trolley 500, and drives the lithium battery module to rise to a specified position through the lifting cylinder 204.
