[0002] Lithium-ion batteries are secondary batteries (rechargeable batteries) that rely primarily on the movement of lithium ions between the positive and negative electrodes to work.

[0003] For example, a positioning mold for lithium-ion battery pack production with authorization announcement number "CN219476886U" can realize arbitrary size adjustment of the positioning mold along one direction; or when loosening any three butterfly nuts, the corresponding clamps can be displaced to realize arbitrary size adjustment of the positioning mold in two vertical directions at the same time, which effectively solves the problem of a wide variety of positioning fixture models and types in the production process of lithium-ion battery packs, improves the versatility of the mold, and thus reduces the investment in the mold. However, before the positioning mold for lithium-ion battery pack production processes the lithium-ion battery, it is necessary to first locate the position of the lithium-ion battery before subsequent production and processing. The lithium-ion battery positioning of the equipment requires manual operation and positioning, which increases the labor force. At the same time, after the positioning mold for lithium-ion battery pack production locates the lithium-ion battery, the subsequent processing position of the lithium-ion battery is fixed and the processing position can no longer be adjusted. The work of the equipment has limitations. Utility Model Content
