Description

Technical Field

[0001] The utility model relates to a material rack for polar plate coils in lithium-ion battery production, belonging to the technical field of battery production. Background Art

[0002] In the production process of lithium-ion batteries, the polar plate coils formed after the coating process are the basic materials for subsequent processes. In the storage and management of polar plate coils, the existing material rack design has the following deficiencies, which not only affect the production efficiency, but also increase the operation difficulty and cost, and may pose a potential threat to product quality at the same time.

[0003] 1. Due to the large weight of the polar plate coils themselves, traditional material racks often require operators to use a lot of strength for the loading and unloading operations of the polar plate coils. High-intensity physical labor not only increases the burden on operators, but also may lead to safety accidents due to improper operation, such as sprains and strains.

[0004] 2. Due to the cumbersome and time-consuming process of loading and unloading polar plate coils, more human resources need to be invested in the entire production process. This not only reduces the overall production efficiency, but also increases the labor cost of the enterprise.

[0005] 3. During the process of manually operating the material rack, due to the uncontrollability of human operations, such as improper operation or negligence, it is very easy to damage the polar plate coils, such as the bending and breaking of the tabs or the indentation and deformation of the polar plate coils. These damages will not only affect the appearance quality of the polar plate coils, but may also have an adverse effect on their electrochemical performance, thereby reducing the overall performance and service life of the battery.
