Description

Technical Field

[0001] The utility model relates to the technical field of cylindrical batteries, in particular to a support cup. Background Art

[0002] Cylindrical batteries are batteries with high capacity, long cycle life, and a wide operating temperature range. Their commercial standardization is relatively mature, and the manufacturing process has also achieved automated production. In order to improve production efficiency, in the automated production process of cylindrical batteries, it is usually necessary to place cylindrical batteries or cells in a tray and transfer them between various processes through a logistics line. Since existing trays are mostly made of insulating materials such as PET, their density is relatively low. After loading cylindrical batteries, when the logistics line is at high speed, the cup is prone to inversion, resulting in poor stability of the tray in the logistics line. In addition, the production conversion process involves product traceability, and the cylindrical battery shell has no directionality, which makes the barcode on the cylindrical battery shell random in direction, resulting in the inability to accurately trace during the production process. In addition, in order to achieve the standardization of the support cup and facilitate processing, and to adapt to the different diameters of the battery cells and batteries, the support cup is generally designed with a certain size of fitting gap. At the same time, the support cups may collide with each other in the high-speed transportation logistics line, and the internal battery cells or batteries may also collide with the support cups during transportation, which will generate noise and damage to the support cups and battery cells. At the same time, in some processes that require inspection or welding, the battery needs to be precisely positioned. If there is an internal fitting gap, the battery will shake, and it is very easy for the welding position to shift or the inspection to be inaccurate, resulting in a decrease in the yield rate of the finished battery product.
