Technical Field

Among them, battery cell injection is a relatively important process, which mainly refers to injecting a certain amount of electrolyte into the battery injection port. In the traditional injection process, there is a lack of effective fixing measures for lithium batteries. The existing electrolyte injection pipe clamp device mainly uses a single electric clamp valve arranged in sequence to control the fluid of the liquid addition. Although the control accuracy of the injection is guaranteed; however, there are still certain problems when the existing lithium battery production injection pipe clamp device is used:

[0003] For example, a liquid injection tube clamp device for battery production with publication number CN219801233U has the following technical solution: it includes a mounting bracket, a movable tube clamp portion for clamping the liquid injection tube, a driving portion for driving the movable tube clamp portion to move on the mounting bracket, and a supporting portion provided on the mounting bracket and cooperating with the movable tube clamp portion; the present application places a plurality of liquid injection tubes between the movable tube clamp portion and the supporting portion, and drives the movable tube clamp portion toward or away from the supporting portion through a driving portion to clamp or release the liquid injection tubes, thereby realizing the start-stop control operation of liquid injection of multiple quantities in the same batch. The arrangement of this structure is not only easy to operate, but also saves equipment operating space; and effectively saves labor resources. However, the existing liquid injection tube clamp device is prone to cause horizontal breakage and damage to the liquid injection tube when squeezing and resisting the liquid injection tube, which is prone to leakage and cannot accurately control the injection amount, affecting the use of the liquid injection tube.

[0004] In view of this, we conducted in-depth research on the above issues, which led to the present case.
