DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a conveyance guide device for a belt-shaped body, and more particularly, to an electrolytic paper formed to be extremely narrow and thin like an electrolytic paper for a small electrolytic capacitor element,
Like an electrode foil, it is extremely narrow and thin, and a strip-shaped body with a lead wire attached and extremely weak strength is lightly transported while sucking to the guide member by the negative pressure of air. The present invention relates to a transporting guide device for a strip which is extremely useful for manufacturing a highly reliable and stable electrolytic capacitor, which can be transported without damage such as damage or cutting of the surface of the strip by reliably guiding the strip.

[0002]

2. Description of the Related Art The negative and positive electrode foils for an aluminum electrolytic capacitor are manufactured so that the surface area is increased by roughening a smooth aluminum foil to increase the capacitance per unit area. But for the anode foil,
Since the surface is roughened, the minimum strength remains.

In recent years, in accordance with the demand for miniaturization of electronic components, when a lead wire is attached by caulking to an electrode foil having a particularly small width, the electrode foil is slightly bent in the width direction at the attaching portion. The phenomenon that turns to
If the electrode foil is forcibly pulled as it is, there is a possibility that the electrode foil may be torn from the mounting position of the lead wire.

On the other hand, a transport guide device provided in a conventional automatic winding machine for electrolytic capacitor elements guides strips such as a negative electrode, a positive electrode foil and an electrolytic paper for insulating them from different directions, and puts them in an overlapping state. The guide member is configured to be guided to the winding portion, for example, by using a leaf spring to press the belt member against the guide member, thereby suppressing the movement of the belt member in the thickness direction and guiding the belt member. Was.

[0005] When a belt such as an electrode foil is guided by using such a transport guide device, the frictional force generated on the surface of the belt increases, thereby causing, for example, an aluminum oxide film added to the surface of the electrode foil and its aluminum oxide film. There has been a problem that the edge is damaged due to a scratch, abrasion, or the like, and aluminum powder is dropped and scattered from the electrode foil roughened by an extra tension.

[0006] In the case of a capacitor element in which the aluminum oxide film is largely damaged, the capacitor element wound by an automatic caulking winder or the like is impregnated with a paste (electrolyte solution), sealed, sealed, and subjected to aging. At this time, it takes time to repair the damaged portion, and if aging is completed in a fixed period of time, the aging is insufficient, so that the leakage current becomes large or a short circuit accident occurs frequently, and the reliability is reduced. There is a problem in that the production of a high and stable electrolytic capacitor is hindered.

[0007]

SUMMARY OF THE INVENTION The present invention has been made in order to eliminate the above-mentioned drawbacks of the prior art, and an object of the present invention is to form a strip having a width slightly larger than the width of the strip. A guide member having a width just enough to fit the body is formed in parallel with the conveying direction of the belt-shaped body, and a guide member having at least one intake hole formed at the bottom of the guide groove; By having an air suction device that sucks the body into the guide groove, the strength is reduced by attaching a thin and low strength electrolytic paper or lead wire, and the width is extremely small. The purpose is to allow a thin, thin electrode foil or other strip-like material to be conveyed while being guided with a slight suction in the thickness direction by the negative pressure of air, thereby reducing the frictional force generated on the surface of the strip. With so and prevent damage, and to prevent the cutting of the strip caused by excessive tension in advance.

Another object of the present invention is to form an air chamber integrally below the guide groove of the guide member and communicate the air chamber with the guide groove through at least one intake hole. When the air in the air chamber is sucked, the air is sucked from the suction hole and a negative pressure acts on the band, and the band is sucked into the guide groove by the negative pressure. Thus, a negative pressure is applied to the strip in a stable manner, and the strip can be reliably guided so as not to be displaced in the width direction and fall off.

Still another object is to use a plurality of the above-mentioned guide members, guide a plurality of belt-shaped bodies which are separately conveyed by a plurality of guide members, collect them at one place, and stack them at a later step in a subsequent process. By providing a guide, the shadow of the electrolytic capacitor element, the anode foil and the electrolytic paper can be guided stably without damage, respectively, so that a reliable and stable electrolytic capacitor can be manufactured. It is.
