Description

Technical Field

[0001] This utility model relates to the field of food processing technology, specifically to a modular assembly device for lithium-ion battery packs. Background Technology

[0002] Lithium-ion batteries are a type of rechargeable battery that primarily relies on the movement of lithium ions between the positive and negative electrodes to function. During charging and discharging, Li+ ions repeatedly insert and extract between the two electrodes. When charging, Li+ ions extract from the positive electrode, pass through the electrolyte, and insert into the negative electrode, which is then in a lithium-rich state. The opposite occurs during discharging. These batteries typically use lithium-containing materials as electrodes and are representative of modern high-performance batteries. Different modules need to be assembled when using lithium-ion batteries, thus requiring a lithium-ion battery pack module assembly device.

[0003] Chinese utility model patent CN219203375U discloses a lithium-ion battery pack module, relating to the field of oxygen purification technology. The module includes a module frame with a load-bearing frame welded to its bottom and stabilizing holes on its surface. The module frame has connecting holes on its outer side and a slide rail on its inner wall, with a telescopic placement platform movably connected to one end of the slide rail. This lithium-ion battery pack module, through a cover plate and rubber pads in the wire pressing mechanism, allows the cover plate to be closed via a round shaft during use. The rubber pads on the inner wall then flatten the wiring connected to the battery pack, maintaining its flatness and stability. The telescopic placement platform and adjustment mechanism allow for size adjustment during use, and the sliding mechanism allows for the movement of the support frame, thus accommodating different lithium-ion batteries and broadening its application range.
