Liquid injection system for battery and transfer device thereof

A transfer device, comprising:

• a base;
• a first jacking mechanism arranged on the base, wherein the first jacking mechanism is configured to drive a fixture of a liquid injection system to move in a height direction of the fixture so that the fixture is assembled to a turnplate of the liquid injection system or separated from the turnplate;
• a driving module configured to drive the first jacking mechanism to move in a first direction, the first direction being perpendicular to the height direction;
• a battery loading and unloading station arranged on a side of the transfer device away from the turnplate in the first direction, the first jacking mechanism being capable of moving the fixture away from the battery loading and unloading station or transferring the fixture to the battery loading and unloading station;
• and
• an adjustment mechanism arranged between the battery loading and unloading station and the turnplate, and configured to adjust a battery on the fixture so that the battery is assembled in place.

A liquid injection system for a battery, comprising:

• a rotatable turnplate, wherein a plurality of mounting regions are arranged on the turnplate, and the mounting regions are arranged at intervals in a circumferential direction of the turnplate;
• a fixture for carrying a battery, wherein one of the turnplate and the fixture is provided with a first plug-in slot, and the other is provided with a first plug-in piece, the first plug-in piece is plug-in fit with the first plug-in slot in a height direction of the fixture, so that the fixture is detachably mounted to the mounting region, and the fixture is capable of moving upward under the action of an external force to be separated from the turnplate, and the turnplate is rotated to drive the fixture to circulate in the circumferential direction of the turnplate;
• and
• a transfer device, comprising a base and a first jacking mechanism arranged on the base, wherein the first jacking mechanism is configured to drive the fixture to move in the height direction of the fixture so that the fixture is assembled to the turnplate or separated from the turnplate;
• wherein the turnplate comprises two carrying members for carrying the fixture, and the two carrying members are spaced apart to avoid the first jacking mechanism.
