Description
Technical Field
The utility model relates to a lithium cell electricity core screening frock specifically is a lithium cell electricity core external dimension detects and positive negative pole ear position's detection and positive negative pole ear wide, high detection frock, belongs to check out test set technical field.
Background
Lithium batteries have penetrated into our lives for many years as novel convenient energy sources, and consumer electronics such as mobile phones, watches, electric toothbrushes, sweeping robots, electric tools and the like are applied to all-around visible lithium batteries; carbon peak reaching, carbon neutralization and environmental protection requirements cause electric automobiles to play more and more important positions in urban vehicles; the lithium battery is more and more important as an energy device in production and life due to the expanding demand of the increasingly huge energy storage field. The method reduces the cost from the raw materials to qualified batteries, does not cause unnecessary waste, improves the yield, and really achieves the purpose that low carbon from the source is also the focus of attention of lithium ion battery production enterprises. In the battery cell assembly section, after the battery cell winding or lamination is completed, the hot-pressing or cold-pressing process is performed, and then the processes of tab welding and shell entering are transferred, generally, the battery cell produced by the assembly line has relatively good consistency, and the tab welding and the shell entering are performed on the battery cell after the hot-pressing and the cold-pressing. However, in a pilot plant test line or a small production line, the mechanical automation degree is far lower than that of a full-automatic production line, many of the production lines are semi-automatic production or manual operation, tension control in the production process of the battery cell cannot be quantized in many times, most of the tension control is judged by the experience of operators, and the consistency of the battery cell wound or laminated is relatively poor. Therefore, the battery cell needs to measure the size of the battery cell before the tab is welded into the shell, and the tab position and the alignment degree of the tab can be evaluated, so that the battery cell is prevented from being successfully inserted into the shell, and the waste of the tab and the labor cost, the machine loss and the time cost generated when the tab is welded are avoided.
