[0002] Lithium battery is a type of battery that uses lithium metal or lithium alloy as the negative electrode material and non-aqueous electrolyte solution. In 1912, lithium metal battery was first proposed and studied by Gilbert N. Lewis. In the 1970s, MS Whit Tingham proposed and began to study lithium-ion batteries. Due to the very active chemical properties of lithium metal, the processing, storage and use of lithium metal have very high environmental requirements. Therefore, lithium batteries have not been used for a long time. With the development of science and technology, lithium batteries have now become mainstream.

[0003] Lithium batteries can be roughly divided into two categories: lithium metal batteries and lithium ion batteries. Lithium ion batteries do not contain metallic lithium and are rechargeable. The fifth generation of rechargeable batteries, lithium metal batteries, was born in 1996. Their safety, specific capacity, self-discharge rate and performance-price ratio are better than lithium ion batteries. Due to its own high technical requirements, only companies in a few countries are currently producing such lithium metal batteries.

[0004] Lithium batteries are equipped with cells, which are connected to tabs, and cell protection plates are installed on the tabs. During the production process, the welding points of the tabs need to be checked and the cell protection plates need to be bent. The existing production process of checking the tab welding points and bending the cell protection plates relies on manual operations, which makes it difficult to control quality, has a high defect rate, and is inefficient.

[0007] The feeding mechanism is arranged at the feeding station of the station rotating disk, and is used to convey the battery cells to be processed and perform two corrections on the battery cells;

[0008] The station rotating disk is driven by a motor to rotate, so as to transfer the battery cells between various stations;

[0009] The tab leveling mechanism is used to perform leveling processing on the tab;

[0010] The welding point detection mechanism is used to detect the welding points of the battery core and the tab to determine whether the welding points are qualified;
