Background technique [0002] "Lithium battery" is a type of battery that uses lithium metal or lithium alloy as the negative electrode material and uses a non-aqueous electrolyte solution. The lithium metal battery was first proposed and studied by GilbertN.Lewis in 1912. In the 1970s, M.S.Whittingham proposed and Began to study lithium-ion batteries.

[0002] "Lithium battery" is a type of battery that uses lithium metal or lithium alloy as the negative electrode material and uses a non-aqueous electrolyte solution. The lithium metal battery was first proposed and studied by GilbertN.Lewis in 1912. In the 1970s, M.S.Whittingham proposed and Began to study lithium-ion batteries. Due to the very active chemical properties of lithium metal, the processing, storage, use and environmental requirements of lithium metal are very high. With the development of science and technology, lithium batteries have become the mainstream now. When performing hemming processing, in the face of the higher efficiency requirements of the new production line, the hemming mechanism of the old model can no longer meet the efficiency requirements. In order to solve this technical obstacle, it is urgent to develop a faster hemming Components replace older model bodies

[0003] In the existing folding process, the battery folding process is divided into two steps, which are first folding and second folding. In the first folding process, the 135° bending is completed, and then the 180° bending battery is obtained by flattening through the ironing mechanism, and then The whole process of edge folding is completed by folding 90° by the two-fold mechanism, which are one-fold and two-fold respectively. Although the number of steps in this step-by-step method is small, the action complexity of a single process is high, and the mechanism programming is difficult. High, the execution speed of the action is slow, and there will be restrictions on the way of moving materials after folding, which will seriously affect the speed of the production line when the production line is in progress, and the old model of folding mechanism can no longer meet the efficiency requirements. In order to solve this Due to technical obstacles, there is an urgent need to develop a faster folding assembly to replace the old model mechanism, so a soft-pack lithium battery 270-degree folding mechanism is proposed here to solve such problems
