Description
Technical Field
[0001] The present invention relates to the technical field of energy storage battery cell assembly, and in particular to an energy storage battery cell assembly process and a device thereof. Background Art
[0002] Energy storage battery cells are a key part of energy storage systems. There are many types of energy storage battery cells, each with its own unique application scenarios and performance characteristics. The following is a detailed introduction to energy storage battery cells:
[0003] Battery cell classification:
[0004] Nickel-based batteries, such as nickel-metal hydride batteries, are known for their high energy density, rapid charge and discharge, light weight, long life, and environmental friendliness. However, they suffer from a slight memory effect and are difficult to manage.
[0005] Flow batteries: Suitable for large-scale stationary energy storage applications. Power and storage capacity can be designed independently. They have high efficiency, long life, deep discharge capability, and are environmentally friendly. They also have flexible layouts, but their energy density is relatively low.
[0006] Sodium-sulfur battery: A secondary battery with metallic sodium as the negative electrode and sulfur as the positive electrode. It has the advantages of high specific energy and no self-discharge, but its safety needs to be paid attention to in practical applications.
[0007] Development trend of energy storage cells:
[0008] With the continuous advancement of technology and market development, the capacity and performance of energy storage cells have continued to improve. For example, CATL's 280Ah large-cell energy storage cell has become a model for many battery cell manufacturers, ushering in the 280Ah era of energy storage cells. Subsequent large-capacity cells such as the 314Ah have also gradually become the industry's preferred choice.
[0009] The energy storage battery cell assembly consists of multiple groups of cells arranged in an alternating positive and negative manner. The positive electrode cover is connected to the positive electrode of the cell by laser ring welding, and the negative electrode cover is also connected to the negative electrode of the cell by laser ring welding. After welding is completed, the welded cell group is placed in the shell and connected to complete the assembly.
[0010] In the prior art, the Chinese invention patent with authorization announcement number CN114464868B specifically relates to an automated assembly station for new energy lithium battery cells; the cells are placed on a first conveyor belt and a second conveyor belt, and when the cells are conveyed to the first robotic arm and the second robotic arm, the positive and negative poles of the cells are identified by a camera component, and then the electric gripper is started to clamp the cells. Based on the image information identified by the camera component, it is determined whether the second rotating component needs to be started, and after adjusting the positive and negative directions of the cells, the first rotating component is started, so that the lifting arm rotates to the top of the assembly frame, and the cells are placed in the corresponding placement slots. The camera component, the first rotating component and the second rotating component cooperate with each other to arrange multiple cells in an alternating positive and negative manner in the assembly frame. Compared with the traditional manual arrangement method, the work efficiency is higher.
