In addition, the static mechanism 2 can sequentially perform the static work on a plurality of pieces to be statically placed 100, improving the working efficiency of the static device. And the structure of the static device is simple and the manufacturing cost is low.

[0035] In one embodiment, as Figure 2 and Figure 3 shown, the transfer mechanism 1 further includes a plurality of first guiding members 14 annularly and spacedly installed on the turntable 12.

[0044] Specifically, during the process of the second driving member 23 driving the static box 21 to move, the second guide member 25 slides along the second guide hole, thereby ensuring the stability of the movement of the static box 21.

[0045] In one embodiment, as Figure 1 shown, the static mechanism 2 further includes a connecting pipe 26 and a pressure gauge 27 both installed on the static box 21. The connecting pipe 26 and the pressure gauge 27 are both communicated with the internal space of the static box 21.

The outside of the battery is a vacuum environment, and the gas inside the battery is at atmospheric pressure. Under the action of the pressure difference, the electrolyte will flow into the battery to accelerate the infiltration of the electrolyte, and the bubbles will move to the outside of the battery until they are discharged. The pressure gauge 27 monitors the air pressure value in the cavity and automatically disconnects when the set value is reached.

[0051] The packaging mechanism 8 is used to package the stationary object 100. It can be understood that the packaging mechanism 8 can press the battery cover onto the battery housing, thereby completing the automatic packaging of the battery.

[0052] The steps for the automatic liquid injection equipment to complete battery packaging are:

[0053] The box 132 with multiple batteries installed is placed in the injection mechanism 5, and the injection mechanism 5 can inject electrolyte into the batteries;

[0054] The injection transfer robot 6 moves the box 132 in the injection mechanism 5 to the turntable 12, and the turntable 12 rotates the box 132 to a normal pressure static station;

[0055] The turntable 12 then drives the box 132 of the normal pressure static station to rotate to the vacuum static station. At this time, the box 132 is located directly above the first driving member 22. The first driving member 22 drives the containing box 13 to move up and away from the turntable 12. The second driving member 23 drives the static box 21 to move down and cover the support plate 131. The static box 21 is evacuated, and the battery is transferred from the normal pressure environment to the vacuum environment. The outside of the battery is a vacuum environment, and the gas inside the battery is atmospheric pressure. Under the action of the pressure difference, the electrolyte will flow into the battery to accelerate the electrolyte infiltration, and the bubbles will move to the outside of the battery until they are discharged. The air pressure gauge 27 monitors the cavity air pressure value and automatically disconnects when the set value is reached;

[0056] The encapsulation transfer manipulator 7 then transports the box body 132 from the vacuum static station of the turntable 12 to the encapsulation mechanism 8, and the encapsulation mechanism 8 can perform the encapsulation work of the battery.
