Full-automatic liquid injection equipment

Abstract

The invention discloses full-automatic liquid injection equipment which comprises a feeding part, a liquid injection part, a standing part and a discharging part, the liquid injection part is of an annular structure, and the feeding part, the standing part and the discharging part communicate with the liquid injection part; the liquid injection part comprises a liquid injection line communicated with the feeding part; and a feeding battery tray loading device, a leakage detection assembly, a liquid injection assembly and a discharging battery tray dismounting device are sequentially arranged on the liquid injection line. In the using process of the device, the battery and the tray are mounted and fixed once, thus, the whole production process can be completed, and, in the processes of liquid injection and standing, secondary assembling, disassembling and fixing of the battery are not needed; and each time when the tray is disassembled and assembled, the loaded tray is disassembled andassembled at the same station, and the unloaded tray is disassembled and assembled at the same station, so that the consistency requirement of the tray is greatly reduced, the problem that the liquidinjection nozzle deviates from the battery cell liquid injection port due to the tray matching problem is avoided, the liquid injection accuracy is improved, and the liquid leakage probability is reduced.

Description

technical field [0001] The invention relates to the technical field of battery liquid injection equipment, in particular to a fully automatic liquid injection equipment. Background technique [0002] Lithium batteries refer to batteries containing lithium (including metal lithium, lithium alloys, lithium ions, and lithium polymers) in the electrochemical system. Lithium batteries can be roughly divided into two categories: lithium metal batteries and lithium ion batteries. Lithium metal batteries are generally non-rechargeable and contain lithium in a metallic state. Li-ion batteries do not contain metallic lithium and are rechargeable. [0003] In the production process of lithium-ion batteries, liquid injection of lithium-ion battery hard-shell batteries has always been the core technical link of battery production. The current liquid injection equipment generally has a high failure rate, low equipment reliability, and short service life of the equipment. The main reas...

AI Technical Summary

Problems solved by technology

The current liquid injection equipment generally has a high failure rate, low equipment reliability, and short service life of the equipment

The main reason for the above problems is that the environment of the liquid injection process is poor, and there is electrolyte leakage in common equipment, which causes a series of equipment problems and production problems
