Abstract

The invention is applicable to the technical field of lithium battery packaging, and provides a sealing device for lithium battery production. The sealing device comprises a base and a rack, and further comprises a pressing assembly arranged on the rack, a bottom die holder arranged on the base through a rotating mechanism, and a top die holder arranged opposite to the bottom die holder and connected with the rack through the pressing assembly; the opposite surfaces of the bottom die holder and the top die holder are rotationally and fixedly connected with a bottom pressing piece and a top pressing piece respectively, and a lithium battery to be sealed is accommodated between the top pressing piece and the bottom pressing piece. The sealing device also comprises a guide triggering assembly which is arranged between the bottom die base and the top die base; and a welding assembly which is arranged on one side of the top mold base and is used for welding the sealing position of the battery. According to the sealing device for lithium battery production, pressing and welding can be effectively matched, the sealing effect is guaranteed, the sealing procedure is simplified, and practicability is high.

Description

technical field [0001] The invention belongs to the technical field of lithium battery packaging, in particular to a sealing device for lithium battery production. Background technique [0002] Due to its small size, high energy density, and rechargeable use, lithium-ion batteries are widely used in smart wearable electronic devices and smart security, and have huge market potential. [0003] The battery casing includes a bottom case, a sealing ring and a cap. The cap is fastened on the bottom case, and the sealing ring is sleeved on the side wall of the bottom case. The side wall of the cap and the side wall of the steel case together form a squeeze on the sealing ring. , to deform the sealing ring to seal the housing. [0004] At present, the necking device is often used to reduce the diameter of the side wall of the assembled battery cap to achieve the purpose of squeezing the sealing ring. It is inconvenient to use, and only one direction is used to compress the seal, a...
