Description

Technical Field

[0001] The utility model relates to the technical field of fixture transfer, in particular to a battery fixture conveying mechanism. Background Art

[0002] During the production of soft-pack lithium batteries, electrolyte needs to be injected into the air bag. Existing lithium batteries generally use manual or automatic injection. Since the automatic injection production method has a high yield rate and a fast production speed, it is widely used. However, the existing automatic injection machine is an assembly line production, and the length of the production line is long, resulting in a large factory area, occupying too much production space, and the production space is not reasonably used, which is not conducive to reducing production costs. At the same time, multiple people are required to operate simultaneously, which makes the labor cost high and affects the benefits of the enterprise.

[0003] In this regard, the invention with application number CN201710560873.1 discloses a lithium battery soft-pack liquid filling machine, which mainly includes a frame, a turntable mechanism is arranged on the frame, and liquid filling tooling, vacuum nitrogen injection tooling and vacuum nitrogen injection heat sealing tooling are arranged in sequence along the outer edge of the turntable mechanism. The turntable mechanism is provided with a jig tooling for placing soft-pack batteries, and also includes a rotating drive mechanism that drives the turntable mechanism to rotate so that the jig tooling is located under the liquid filling tooling, vacuum nitrogen injection tooling and vacuum nitrogen injection heat sealing tooling in sequence. The lithium battery soft-pack liquid filling machine of the present invention has a compact structure and occupies a small space. Each device only requires one person to operate, and the operation is convenient. At the same time, the equipment can simultaneously perform liquid filling and packaging operations of multiple soft-pack batteries during the production operation, thereby improving production efficiency.

[0004] When the liquid injection fixture cooperates with the liquid injection mechanism, it needs to be transferred to the liquid injection station and sealed with the liquid injection cavity. The existing liquid injection fixture is prone to exceeding the stroke during transfer, resulting in the liquid injection fixture and the sealed cavity being unable to be aligned. When the liquid injection cavity approaches the liquid injection fixture, it collides with the liquid injection fixture, damaging the equipment and affecting the injection efficiency.
