Function overview
The equipment is mainly used for automatic conventional vacuum injection production of square aluminum shell power lithium batteries. It is equipped with conveyor belt incoming material, code scanning before injection, short-circuit Hi-pot test, weighing before injection, bad product sorting collection, automatic filling fixture, sealing detection before injection, automatic vacuum filling, high and low pressure circulation static, filling cup residual collection, cleaning of filling cup and nozzle, unloading conveyor belt fixture after injection, weighing after injection, automatic filling port DMC cleaning, filling port Rubber nail, rubber nail detection, conveyor belt discharge and other functions.

Technical characteristics
● Liquid injection test: no pressure difference inside and outside the battery is used
1) Prevent the battery from deforming the shell during the static process of positive and negative pressure during liquid injection;
2) Shorten battery static time and improve equipment efficiency;
3) During liquid injection, the positive nitrogen pressure inside and outside the battery is ≤0.6MPa;
● Before injection, add the injection cup and injection nozzle cleaning system to improve injection accuracy and avoid secondary pollution of the injection nozzle to the battery;
● After injection, add the injection nozzle to the residual liquid system to avoid electrolytic body fluid pollution of the battery housing;
● The injection nozzle adopts a conical insert type of injection, avoiding the step of the battery injection port, and the electrolyte at the right Angle connection can not be cleaned;
● The production capacity of the equipment is not limited by the static process time, when the production capacity is unchanged or increased and the process time is increased, the equipment can increase the liquid injection unit to meet the production requirements.
