Technical Field

[0001] The utility model relates to the technical field of lithium battery welding fixtures, in particular to a fixture for lithium battery production with a quick-change die. Background Art

[0002] Lithium batteries are a type of battery that uses lithium metal or lithium alloy as positive and negative electrode materials and a non-aqueous electrolyte solution. During the production and processing of lithium batteries, the required tabs and pole pieces will be connected to the lithium batteries through welding equipment. In order to prevent the lithium batteries from shaking during the welding process, welding fixtures are required to fix the lithium batteries to prevent the lithium batteries from shaking and causing inaccurate welding points, which will affect the production quality of the lithium batteries.

[0003] Now many manufacturers produce lithium batteries of different sizes. The fixtures used to weld the tabs at one end of the lithium battery are mostly fixed to the welding equipment by screws. It takes a long time to disassemble and replace the entire fixture when encountering lithium batteries of different sizes, which is quite troublesome.

[0004] Based on this, the utility model designs a quick-change mold clamp for lithium battery production to solve the above problems. Utility Model Content

[0011] Preferably, a handle is hingedly connected to one end of the threaded rod away from the top block.

[0012] Compared with the prior art, the beneficial effects of the utility model are as follows: different matching top molds and auxiliary molds can be set in advance according to the sizes of lithium batteries to be produced. When lithium batteries of different sizes need to be processed, the electromagnet in the top block disconnects the magnetic attraction with the first plug-in block, and the electromagnet in the auxiliary block disconnects the magnetic attraction with the second plug-in block. Personnel can remove the top mold and the auxiliary mold and reinstall top molds and auxiliary molds suitable for different sizes. The top mold uses the first plug-in block, and the auxiliary mold uses the second plug-in block and the electromagnet to maintain stability. Subsequently, when welding and processing lithium batteries of different sizes, the removal and replacement of the top mold and the auxiliary mold are more convenient and quick.
