Description

Apparatus for pouring electrolyte in capacitor}

The present invention relates to a capacitor electrolyte impregnation apparatus for impregnating an electrolytic solution with an electrical material including a cathode material, a cathode material, a separator, and the like in a capacitor case.

Capacitors are widely used in many devices of important elements of electrical and electronic equipment, and the capacitor manufacturing process includes a capacitor case, and an electrical material including a cathode material, a cathode material, and a separator (hereinafter referred to as a capacitor device). After the impregnation process of impregnating the capacitor element is performed, the capacitor element impregnated into the capacitor case is installed.

At this time, since the electrolyte used in the impregnation process evaporates quickly, if the assembly process of inserting the impregnated capacitor element into the case and sealing is not performed quickly, the electrolyte impregnated in the capacitor case evaporates and the quality of the capacitor deteriorates. Problems have arisen, and thus various inventions have been made for an apparatus and a method for quickly installing an inside of a capacitor case in a state in which evaporation of an electrolyte impregnated in a capacitor element is suppressed after an impregnation process.

In addition, the control device 20 is 5 to 10% of the remaining electrolyte solution 4 when the electrolyte solution (4) contained in the impregnation container (3) reaches the minimum appropriate amount to recover the electrolyte solution 4 is the second storage unit ( 12, so that the impurity eroded to the lower portion of the electrolyte solution 4 during the impregnation process is disposed of by being supplied to the waste storage unit (not shown) to the outside.

In addition, the control device 20, when all the electrolyte solution 4 contained in the first storage unit 11 designated as the supply tank is exhausted, the first storage unit 11 to the recovery tank, the second storage unit supply tank 12 In the following process, the same process is re-executed as described above, so that the electrolyte is not inefficiently recycled through a simple algorithm, thereby reducing the manufacturing cost.

In addition, when the capacitor to be manufactured is an electric double layer capacitor (EDLC), the expensive oil-based electrolyte is recycled and used to further reduce manufacturing costs.

As described above, the capacitor impregnation device 1 according to the embodiment of the present invention does not have the rubber cover 6 installed because the rubber cover 6 is installed on the upper portion of the capacitor element 2 when the capacitor element 2 is impregnated. Compared to the case, the electrolyte evaporation rate drops to 5%, and as the electrolyte evaporation rate is reduced, the product quality is excellent and the defective rate is reduced.

In addition, the capacitor impregnation device 1 includes a plurality of capacitor elements 2 and rubber covers 6 mounted on the element seating plate 9 so that each of the capacitor elements 2 and the rubber covers 6 is impregnated with the impregnation tube 3. Since the impregnation process and the assembling process of the coupling device 5 are performed, a large amount of capacitor processing is possible in one device, and thus the yield is significantly increased.
