Abstract

The invention provides a liquid injection method for capacitor liquid injection. The liquid injection method comprises the following steps: providing a capacitor to be injected with electrolyte; performing liquid injection on the capacitor for the first time; providing a vacuum device, and vacuumizing the capacitor; and second liquid injection is carried out on the capacitor. When the liquid injection method is adopted to perform liquid injection operation on the capacitor, the vacuumizing process is added between the two liquid injection steps, so that the filling rate of the electrolyte in the capacitor can be ensured, the injection precision of the electrolyte can be ensured, the liquid injection efficiency is ensured, and the use effect is good.

Description

technical field

[0001] The invention relates to the technical field of capacitor manufacturing equipment, in particular to a liquid injection method for capacitor liquid injection and capacitor liquid injection equipment. Background technique

[0002] When producing capacitors, the electrolyte must be injected into the capacitor. The current injection equipment generally injects liquid into the capacitor in a quantitative form. This method needs to be adjusted by a quantitative method, which is not only difficult to debug, but also difficult to operate. It is very inconvenient. If the liquid flow rate is too large, it is likely to overflow, resulting in insufficient electrolyte in the capacitor, thereby reducing the yield of the capacitor.

[0003] Therefore, how to ensure the liquid injection amount of the capacitor during the liquid injection process is an important issue to be solved urgently in the industry at present. SUMMARY OF THE INVENTION
