Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to an electrolytic capacitor element winding device that continuously winds an electrolytic capacitor element.

[Conventional technology]

An electrolytic capacitor has an electrolytic capacitor element sealed in an outer case, and external terminals for connecting the electrolytic capacitor element and an external circuit are drawn out from the outer case.

As shown in FIG. 8(A), the electrolytic capacitor element 2 includes a separator 8 between an anode foil 4 and a cathode foil 6 in the form of a strip.
, IO interposed therebetween, and tabs 12 and 14 serving as external terminals are connected to the anode foil 4 and the cathode foil 6.

The manufacturing process of this electrolytic capacitor element 2 consists of a processing process of the anode foil 4 and the cathode foil 6, and a winding process. In the processing process, the anode foil 4 and the cathode foil 6 are etched,
Chemical conversion treatment, cutting treatment, and connection treatment of the tabs 12 and 14 to the anode foil 4 and the cathode foil 6 are performed on the anode 'f34. Therefore, in the winding process, the separator 8.1 is placed between the anode fr34 and the cathode foil 6 to which the tab 12.14 is connected.
0 is inserted and rotated using the winding shaft to complete the electrolytic capacitor element 2. Then, as shown in FIG. 8(B), a holding tape 16 is attached to the wound electrolytic capacitor element 2 as a final step of the winding process to prevent loosening of the winding.

[Problems to be Solved by the Invention] Conventionally, such winding processing of electrolytic capacitor elements has had a great effect on reducing manufacturing costs, and has been automated.

By the way, the processing of one electrolytic capacitor element 2 includes supplying the anode foil 4, cathode foil 6, and separator 8, 10 to the winding shaft, rotating and stopping the winding shaft, and holding tape 16 for the wound electrolytic capacitor element 2. , and removal of the electrolytic capacitor element 2. Even if the rotational speed of the winding shaft is increased, it is impossible to increase production efficiency because other processes require time.

In addition, when multiple winding devices are placed side by side, the amount of winding can be increased in proportion to the number of winding devices, but the price of the winding device will affect the production cost, etc. Experience tells us that an increase in production efficiency does not necessarily lead to an increase in production efficiency.
