Description

Technical Field

[0002] The electrolyte of a lithium battery is the carrier of ion transmission in the battery. It can ensure that there are enough lithium ions moving back and forth between the positive and negative electrodes during the charge and discharge process, thereby achieving a reversible cycle. Therefore, the amount of electrolyte injected and the degree of absorption of the electrolyte by the positive and negative electrodes are key factors affecting battery performance. The filling of the electrolyte usually needs to be completed through a filling device.

[0003] The current filling device is generally composed of a bracket, a conveying device, a lifting frame, a delivery pump and a filling head. When working, the conveying device drives the battery to move to the center of the filling device, and then drives the filling head downward through the lifting frame, so that the filling head enters the battery, and then the delivery pump adds the filling liquid to the battery through the delivery pipe. However, the existing filling device is usually unable to fix the battery, resulting in the battery being easily displaced when the electrolyte is added to the battery, which in turn causes the electrolyte to spill to the outside of the battery, thereby polluting the battery and affecting the battery quality. Therefore, the inventor proposes a liquid injection device for lithium battery processing to solve the above problems. Utility Model Content
