Description

Technical Field

[0001] The invention belongs to the technical field of lithium battery formation testing, and in particular relates to a negative pressure restraint integrated tray. Background Art

[0002] With the rapid development of the lithium battery industry, the production effect and efficiency requirements of lithium batteries are becoming increasingly stringent. At present, in the production process of lithium batteries, negative pressure nozzles are required to extract and remove the gas inside the battery to prevent bubbles in the electrolyte from affecting the battery function. In conventional battery formation equipment, the negative pressure nozzle and the tray where the battery is placed are independent of each other. Due to insufficient airtightness, the battery filling port is exposed, resulting in electrolyte contamination. Therefore, the production process is usually carried out in a controlled plant with a high temperature of 45 degrees to prevent impurities from entering the electrolyte. In order to control the air humidity in the controlled plant, a large number of dehumidifiers are required, which consumes a lot of energy. Summary of the invention

[0003] The present invention aims to solve the above problems by providing a negative pressure restraint integrated tray that integrates a battery tray with a negative pressure suction nozzle. The idea is to directly connect the negative pressure suction nozzle with the battery's liquid injection port to increase the air tightness of the negative pressure suction nozzle during the vacuuming process, thereby significantly reducing the impact of ambient humidity on the battery formation process.
