[0120] The working principle of the above technical scheme is as follows: in order to realize a multi-stage vacuum glue filling system, the present invention proposes a colloid metering module, which is used to add the first colloid and the second colloid into their respective corresponding tanks, and use a PLC controller to control the metering module to meter the first colloid and the second colloid in the tank; a colloid mixing module is proposed, which is used to use a PLC controller to control the colloid mixing module to mix the measured first colloid and the second colloid to obtain a mixed colloid; a colloid perfusion implementation module is proposed, which is used to use a PLC controller to control the vacuum module to control the vacuum degree of the vacuum chamber; control the glue amount module to control the glue amount of the mixed colloid; control the glue filling module and the three-axis servo manipulator in the vacuum chamber to perfuse the mixed colloid after the glue amount control into the glue-filled battery.

[0121] The beneficial effect of the above technical solution is: adopting the solution provided by this embodiment, by adopting a multi-stage method to set different vacuums and different glue filling speeds to fill the battery, there will be no bubbles in the glue inside the battery, so that the battery module can be fully wrapped, and the battery module will not be corroded by water, making the battery more stable and safer underwater. According to the same volume of the inner cavity, multiple vacuums and multiple glue filling speeds can be used to adjust the glue filling by themselves, reducing the error amount, so that there will be no voids in the glue inside the product, thereby solving the safety and waterproofness of using batteries underwater.
