Description

Technical Field

[0001] The invention relates to the field of new energy technology, and in particular to a double-row module stacking tray. Background Art

[0002] Due to the energy and environmental problems worldwide caused by the automobile industry, the development of new energy vehicles has become an urgent task in today's world. New energy vehicles are an effective way to solve the energy and environmental problems faced by automobile transportation. With the continuous advancement of the green environmental protection theme, the use of electric vehicles has increased year by year. The battery module is an important component of the electric vehicle power system, and the tray is a component in the battery module used to support the battery cell.

[0003] For example, in the manufacturing process of new energy battery packs, multiple battery cells are usually assembled together and the overall structure is fixed by side panels and end panels. Currently, the most common method is to weld the side panels and end panels together.

[0004] Therefore, before welding the battery pack, multiple battery cells, side panels and end plates need to be transported to the welding station in the prescribed quantity ratio for the production of the battery pack. At present, the transportation of battery cells adopts the stacking action as an important part of the module molding process. During the battery cell stacking process, the battery cells are usually automatically loaded and sorted, and the battery cells are fixed by a fixture and then transported to the belt line. The direction of the battery cells is identified by the rotation of the module manipulator, and then the battery cells are placed on the carrier for secondary stacking. This cycle completes the battery cell stacking. After the battery cell stacking is completed, the corresponding side panels and end plates are transported to the welding station by a manipulator or other conveying device, and the welding is completed after the battery cells, side panels and end plates are positioned. This method of stacking batteries and conveying side panels and end plates separately seriously reduces the degree of automation and results in low production efficiency. Summary of the invention
