The electrolytic solution is sucked up and supplied to the vacuum impregnation tank by vacuum pressure to impregnate the electrolytic capacitor element with the electrolytic solution. BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method and an apparatus for electrolytically impregnating an electrolytic capacitor element with vacuum so as to manufacture a capacitor element.

及び装置が実用に供されている。2. Description of the Related Art Conventionally, the lead wires of a plurality of electrolytic capacitor elements are aligned and held by a clamp jig to convey the electrolytic capacitor elements into a vacuum impregnation tank, and the inside of the vacuum impregnation tank is evacuated to a main body of the electrolytic capacitor elements. A method and an apparatus for supplying an electrolytic solution and impregnating the electrolytic solution inside the main body of the device after removing the internal air have been put to practical use.

組立機の稼動率を低下させる原因ともなっていた。However, according to the conventional method and apparatus, since the electrolytic solution supplied to the vacuum impregnation tank is released into the atmosphere and contains air in the solution, the electrolytic solution is supplied to the vacuum impregnated tank. At this time, the air contained in the liquid diffuses as fine bubbles and a part of the air penetrates into the electrolytic capacitor element together with the electrolytic solution to form a pinhole-like unimpregnated portion. However, there is a drawback in that the electrical characteristics of the electrolytic capacitor using is deteriorated. Further, since the air in the electrolytic solution rapidly diffuses into bubbles in the vacuum impregnation tank, the electrolytic solution becomes a boiling state and jumps to various parts, for example, it adheres to the lead wire and is used in the soldering work in a later process. There was a drawback that caused poor soldering. This has also been a cause of lowering the operating rate of the automatic assembly machine.

In addition, there is a drawback in that it is impossible to sufficiently impregnate the central portion of the large-sized electrolytic capacitor element with the electrolytic solution. Further, such a phenomenon is remarkable in an electrolytic solution having a high viscosity used for a high-voltage electrolytic capacitor, and there is a drawback that a large-sized apparatus must be used to impregnate the electrolytic solution having a high viscosity.

ことができる。The above-mentioned impregnation cycle is repeated one after another to automatically impregnate the electrolytic capacitor element 10. And electrolyte
Since 11 is in vacuum most of the time of the impregnation process, there is little opportunity for air to enter from the outside, and since the electrolytic capacitor element 10 is impregnated in a defoamed state, only the conventional one with an outer diameter of about 16 mm, for example, can be used. Even in the case of a device that cannot be treated, the high-viscosity electrolytic solution 11 can be completely impregnated into the central portion of the electrolytic capacitor element 10 having an outer diameter of 18 mm or more. Further, since the exchange of the electrolytic solution 11 between the respective tanks is performed only by the vacuum pressure and no dedicated pump or the like is required, there is no fear of failure and the manufacturing cost of the device can be greatly reduced.
