Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a method of manufacturing a capacitor having the same element.

Generally, when forming a multi-element capacitor by coaxially winding two metallized films with vapor-deposited electrodes, a separator is created between the electrodes by scattering part of the vapor-deposited charge or cutting the metallized film. It is insulated and wound with a .

Conventionally, capacitors such as those described above are manufactured using vapor-deposited electrodes 11L, 2 of metallized film 1.2 as shown in FIG. 1 or 2.
The vapor deposited electrode 1a is divided into the core side and the outer peripheral side by scattering a part of &, and the metallized film 1.2 is placed between the divided electrodes G.
A capacitor element 4 is formed by coaxially winding it with the other metallized film 2 with a wider insulating separator 3 made of paper, plastic, etc. It was configured. 1b
, 2b is a plastic film. Therefore, the metallicon metal adheres to the ends of the insulating separator 3.
Mechanically remove the metallicon metal 5 by scraping off the metallicon metal 5 adhering to the insulating separator 3 or cutting the protrusion 3 & of the insulating separator 3 by one or two rotations,
Although the capacitor elements on the core side and the outer circumferential side were insulated, there were problems such as requiring a lot of man-hours, making automation difficult, and causing sparks if metal powder remained in the area where the metallcon metal 5 was removed.

In order to solve the above-mentioned problem, the present invention involves pasting an adhesive tape on at least one end surface of an insulating pallet in advance, adhering metallicon metal, and then peeling off the deso to remove metallicon metal adhering between the elements. This is a method of manufacturing a capacitor characterized by the following.

The present invention will be explained below with reference to embodiments shown in FIGS. 4 to 8.

FIG. 4 shows an insulating separator, and an adhesive tape 6 is attached to the end face of the insulating separator 3. As shown in FIG.

Zetsu&Se/<V-Yu 3 is made of paper, glass film, etc., and is coated with a release material such as silicone resin.

The insulating separator 3 having the adhesive tape 6 is inserted between the divided electrodes G of the metallized film 1.2 in the same manner as in FIG. 1 or 2 and wound to form a multi-element capacitor,
Metallicon metal 5 such as zinc or solder is attached to both end surfaces by a spray method. At this time, metallicon metal 5
is uniformly adhered to the end face of the insulating separator 3, as shown in FIG. Next, when the adhesive tape 6 affixed to the end face of the insulating separator 3 is peeled off, the metallicon metal 5 attached to the adhesive tape 6 is removed from the end face of the capacitor element 4 along with the adhesive tape, and as shown in FIG. Metallikon gold R5 attached between the side and outer peripheral side elements is reliably removed.

Figure 7 shows the capacitor element 4 after the adhesive tape has been peeled off, and since the metallcon metal 5 has been removed from the protrusion 3a of the insulating separator 3, there is insulation isolation between the elements on the core side and the outer circumferential side. It will be done.

Next, the above-mentioned metallikon gold R5 attachment part and the external terminal are connected with a lead-out lead, and the product is housed in an exterior case and sealed to complete the product.

Therefore, according to the manufacturing method of the present invention, it is possible to reliably and easily remove the entire set of metallcones 5 attached between the elements on the core side and the outer peripheral side by peeling off the adhesive tape 6, and no sparks are generated. The withstand voltage between each element is stabilized, and an extremely safe high-b capacitor can be obtained.

FIG. 8 shows another example of the insulating separator 3 with adhesive tape 6 pasted thereon, (a) shows one in which the adhesive tape 6 is folded back and pasted on the end face, (b) shows one in which it is pasted on one side, and (c) 2) has a slit 7 near the end surface that can be pasted on the entire surface and is easy to cut and peel off, and 2) has a slit 7 near the end surface that can be pasted on one side and is easy to tear off, and is the same as above. You can get the following effect. Furthermore, when the above insulating tapes (c) and 2) are used, there is no peeling or lifting of the insulating tape during the winding process, and infiltration of metallicon metal can be reliably prevented.

As mentioned above, the capacitor manufacturing method of the present invention is extremely advantageous in terms of productivity and safety, and is of great industrial and intellectual practical value.
