Description

Technical Field

[0001] This utility model relates to the field of lithium battery production and processing technology, and in particular to an electrode tab straightener. Background Technology

[0002] Electrode tab aligners are key auxiliary equipment in the manufacturing process of lithium-ion batteries. Their core function is to correct positional deviations and morphological defects of the tabs on the battery electrodes, ensuring that the tabs are accurately aligned in subsequent processes, thereby guaranteeing the safety, consistency and performance stability of the battery.

[0003] However, some traditional electrode tab processing devices still rely on manual operation in the core leveling and alignment stages. This not only results in low work efficiency and difficulty in adapting to the pace of mass production, but also suffers from insufficient electrode leveling accuracy and large deviations in tab alignment, making it difficult to consistently ensure the positional accuracy of the tabs. This limitation not only directly leads to reduced production efficiency and increased product scrap rate, but also has a chain reaction of negative impacts on the quality of subsequent cell assembly and the core performance of the battery. On the other hand, the electrode clamping structure of traditional devices has poor adaptability. When changing to different specifications of electrodes, it is necessary to manually disassemble and replace special clamps, which is a cumbersome and time-consuming process. At the same time, the clamping force depends entirely on manual adjustment. Insufficient clamping force can easily lead to misalignment of the electrode during processing, while excessive clamping force can cause the active material of the electrode to fall off or the substrate to be damaged, failing to flexibly meet the diverse electrode processing needs.

Beneficial effects

[0013] 1.
