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.

[0003] The utility model with the publication number CN220710379U proposes a negative pressure restraint integrated tray. By directly installing the negative pressure mechanism on the battery tray, the negative pressure nozzle is directly connected to the filling port of the lithium battery, omitting the common infusion catheter connection link between the negative pressure nozzle and the battery, and enhancing the airtightness of the process of negative pressure extraction of gas in the battery. However, the battery tray used in this design is large in size, which is prone to inaccurate precision when docking with the negative pressure mechanism and difficult to adjust; the size between the negative pressure mechanisms also has errors caused by processing, resulting in the inability of the negative pressure nozzle to accurately align with the battery filling port, affecting the efficiency of exhaust gas extraction. In addition, the up and down strokes of the negative pressure nozzle cannot be accurately adjusted, which can easily lead to insufficient or excessive docking between the negative pressure nozzle and the battery filling port. Insufficient docking will cause poor sealing and air leakage, and excessive docking will cause the negative pressure nozzle to be damaged. Summary of the invention

[0004] In view of the above problems, the present invention proposes an integrated negative pressure restraint pallet, the design concept of which is to integrate the negative pressure suction nozzle on a whole negative pressure fixing plate connected to the restraint tray assembly, and to fine-tune the height of the negative pressure fixing plate through an additional positioning device, so as to accurately align the negative pressure suction nozzle and the battery filling port while ensuring air tightness.
