Technical Field

[0001] The present invention relates to the technical field of battery nozzle extraction, and specifically to an automatic nozzle extraction tooling for square batteries. Background Art

[0002] The negative pressure formation process is one of the most important processes in the latter stage of square lithium-ion batteries. The purpose of formation is to form a protective film on the positive and negative electrodes. The quality of this film depends on formation systems, conditions, temperature, etc. During the formation process, the battery will generate gas, which needs to be extracted through a negative pressure nozzle. Over time, electrolyte crystals will remain in the negative pressure nozzle during production, affecting the air extraction effect. The negative pressure nozzle needs to be regularly removed and cleaned to ensure the use effect. A Chinese invention patent with the application publication number CN117324923A discloses an automatic nozzle extraction device for a lithium battery formation negative pressure device, including a base, a nozzle extraction assembly, and a power system. When the formation device changes models, resulting in changes in the number and position of the nozzles, the clamping space of the nozzle extraction tongue can compensate for the position and number changes of the nozzles. Therefore, there is no need to adjust and replace the nozzle extraction assembly, improving the adaptability of the nozzle extraction device.
