Abstract

The invention discloses a precise vacuum sealing device. The device comprises a sealed cavity, a head assembly, a bayonet assembly, a cell positioning assembly and an air bag pressing plate assembly,wherein the head assembly, the bayonet assembly, the cell positioning assembly and the air bag pressing plate assembly are arranged in the sealed cavity. The cell positioning assembly and the air bagpressing plate assembly are located on both sides of the head assembly respectively. The bayonet assembly is located on the air bag pressing plate assembly. The air bag pressing plate assembly is provided with a bayonet hole corresponding to the bayonet assembly. A suction assembly is sealedly connected with the lower part of the air bag pressing plate assembly. The suction assembly comprises a liquid receiving tank and a suction nozzle. The bayonet hole penetrates the air bag pressing plate assembly and is communicated with the liquid receiving tank. The suction nozzle is arranged below the liquid receiving tank and protrudes from the lower part of the sealed cavity. According to the invention, only the puncture opening of an air bag is used as a suction port, which ensures that an electrolyte can be sucked into the liquid receiving tank in accordance with the vacuum flow direction without splashing; the head and the battery surface are prevented from pollution and corrosion; and thequality of a cell is improved.

Description

technical field [0001] The invention relates to the technical field of lithium battery packaging, in particular to a precision vacuum sealing device. Background technique [0002] Lithium-ion battery cells need to pre-seal the side of the air bag immediately after the electrolyte is injected, referred to as a letter. After the letter is completed, the battery needs to be formed. A certain amount of gas will be generated during the formation process, and the exhaust gas needs to be pumped out. Then carry out the second encapsulation, referred to as the second encapsulation. During the second sealing, the main body of the cell needs to be placed on the backing plate, the air bag is pierced with a bayonet, and the waste gas and excess electrolyte are pumped out at the same time, and then sealed in the second sealing area with a head. In the prior art, the electric core is placed in the sealed cavity to puncture the air bag with a bayonet, and then the sealed cavity is pumped b...
