Description

Technical Field

[0001] The utility model belongs to the field of lithium battery manufacturing, in particular to a tool for cleaning a square lithium battery formation probe. Background Art

[0002] Cleaning the formation probe is a relatively difficult task in the industry. During the production process of the battery, according to the process flow, the battery enters the negative pressure formation and detection capacity division, and the probe is in close contact with the battery pole for charging and discharging operations. After the operation is completed, long-term use will cause dust to adhere to the probe. Dust adhered to the probe will affect the accuracy of the voltage and current collected during charging and discharging. Inaccurate current and voltage of the entire basket of batteries will affect battery performance. The probe needs to be cleaned in time to ensure battery performance. Since the existing equipment does not have probe cleaning tooling, manual cleaning is required. Each storage location has 48 probes, and employees need to work in a small environment, which is not easy to operate. It takes at least 10 minutes for one storage location. The efficiency is low and only a small part can be cleaned. Due to the height of the equipment, only the lower storage locations on the inside can be cleaned. The high-rise storage locations require climbing operations, which is very dangerous. Basically, if they are not cleaned, the probe contact impedance will increase over a long period of time, affecting the stability of the equipment.
