Description

Technical Field

[0001] The utility model relates to the technical field of battery side edge sealing and molding equipment, in particular to an L-shaped battery side edge sealing and molding automatic line. Background Art

[0002] Lithium batteries are a type of battery that can be charged and discharged multiple times and can be recycled. They are the mainstream battery today because of their large capacity. With the development of new energy companies, the demand for lithium batteries is increasing, and it is particularly important to improve the production efficiency of lithium batteries. However, the chemical properties of lithium metal are very active, and the processing, storage, and use of lithium metal have very high requirements on the environment.

[0003] In the production process of lithium batteries, packaging is a crucial link. After lithium batteries are carefully assembled and tested, they are packaged to protect the internal battery cells and ensure their safe use. In this process, the excess side seals need to be precisely cut off because the presence of the side seals may affect the size and appearance of the lithium battery. The side seals after cutting also need to be processed by gluing and folding to ensure their firmness and stability. However, the current lithium battery side seal molding equipment is mainly used for the side seal molding of square lithium batteries, and cannot be adapted to L-type lithium batteries. It has poor compatibility and low applicability. For example, when cutting the side seals, due to the different shapes of L-type lithium batteries and square lithium batteries, and the number and position of the cut side seals are different, the existing lithium battery side seal molding equipment cannot cut the side seals of L-type lithium batteries.

[0004] The above defects need to be solved urgently. Utility Model Content

If there is a leak on the L-type battery 7, the L-type battery 7 will bulge under the action of the high pressure, that is, the thickness of the L-type battery 7 will increase, so as to detect whether the L-type battery 7 is cut by the trimming machine 1 in the process of cutting off the excess side sealing edge. The leak detection moving component 222 is used to transport the L-type battery 7 into the high-pressure chamber 221 for leak detection.
