[0010]

An embodiment of the present invention will be described below with reference to the drawings. (First Embodiment) FIG. 1 is a view showing a tape-shaped body 31 serving as a base of a carrier 30 according to a first embodiment of the present invention, which is before bending, and FIG. (B) is a sectional view showing an AA section of (a).
FIGS. 2A and 2B are views showing the carrier 30 formed from the tape-shaped body 31 of FIG. 1, wherein FIG. 2A is a plan view and FIG. 2B is a side view.

The tape-shaped body 31 is formed in a tape shape from a thin plate of a metal material or a resin material, and has a longitudinal direction in the left-right direction in the figure. First, a hole 32 is formed by punching in a U-shape at regular intervals in the longitudinal direction of the tape-shaped body 31. Then, a hole 32 in the longitudinal direction of the tape-shaped body 31 is formed.
A groove 33 having a V-shaped cross section is formed by bending or drawing between substantially the center of the outer edge of the tape-shaped member 31 and both side ends of the tape-shaped body 31. The groove 33 is for supporting a lead wire for an electrolytic capacitor, and is formed in such a size that the lead wire can enter the V-shaped portion.

Further, by forming the above-described hole 32, a tongue-like piece 34 is formed inside the hole 32. Tongue 34
Is for holding the lead wire, has a fixed end and a free end in the longitudinal direction of the tape-shaped body 31, and has a cantilever shape. Then, the vicinity of the fixed end of the tongue-shaped piece 34 is bent such that its free end faces the convex side of the groove 33. Here, the formation of the groove 33 and the tongue piece 34
Is bent once by press working. Thus, the carrier 30 is formed from the tape 31. Therefore, one punching process and one
Since the carrier 30 can be formed by performing the pressing twice, the manufacturing cost can be reduced.

Next, the mounting of the lead wire for the electrolytic capacitor to the carrier 30 will be described. The carrier 30 is attached to a device for mounting lead wires for electrolytic capacitors, and is transported intermittently. FIG. 3 is a side view showing a state where the electrolytic capacitor lead wire 21 is mounted on the carrier 30. On the lower side of the carrier 30 (projecting side of the groove 33) and substantially at the center position in the width direction of the carrier 30,
The lifting member 40 (in the figure, 2
(Dotted line). When the lead wire 21 is mounted on the carrier 30, the carrier 30 is positioned so that the vicinity of the free end of the tongue 34 is located above the lifting member 40, and the lifting member 40 is raised.

Thus, the lifting member 40 is connected to the tongue 3
4 comes in contact with the vicinity of the free end, and the tongue-shaped piece 34 is lifted upward (FIG. 3A). Accordingly, when viewed from the side of the carrier 30, the space formed by the groove 33 and the tongue-shaped piece 34 is widened.
It can be inserted inside. Furthermore, the space defined by the groove 33 and the tongue-shaped piece 34 at this time is much larger than the outer diameter of the lead wire 21, so that the lead wire 21 can be easily arranged. Therefore, the mounting work is simplified, and the work efficiency can be improved.

When the lead wire 21 is disposed, the lifting member 40 is lowered, and the contact between the lifting member 40 and the tongue 34 is released (FIG. 3B). As a result, the tongue-shaped piece 34 presses the upper part of the lead wire 21 and the lead wire 21
Is fixed. Accordingly, the lead wire 21 is supported at three places on the two inclined surfaces of the groove 33 and the lower surface of the tongue-shaped piece 34 and is pressed by the urging force of the tongue-shaped piece 34, so that the lead wire 21 is completely fixed to the carrier 30. . Therefore, it is possible to prevent the lead wire 21 from dropping from the carrier 30.

Furthermore, since the cross section of the groove 33 is V-shaped, the center of the cross section of the lead wire 21 is arranged on the center line of the cross section of the groove 33, so that the lead wire 21 is accurately positioned with respect to the carrier 30. You. Therefore, for example, only the lead wire 21 is mounted on the carrier 30 and the lead wire 2
1 can improve the welding position accuracy when welding the electrode terminals.

FIG. 4 is a plan view showing a state in which the lead wires 21 (to which the electrode terminals 20 are welded) are sequentially mounted on the carrier 30 as described above. The carrier 30
In this state, it is wound on a reel or the like and sent to the next step.

(Second Embodiment) FIG. 5 shows a tape-like body 3 serving as a base of a carrier 30A according to a second embodiment of the present invention.
FIG. 1A is a diagram showing one before bending.
Shows a plan view, and (b) shows a sectional view showing a BB section of (a). FIGS. 6A and 6B are views showing a carrier 30A formed from the tape-shaped body 31 of FIG. 5, wherein FIG. 6A is a plan view and FIG. 6B is a side view. Hereinafter, the second embodiment will be described mainly with respect to differences from the first embodiment.

First, as in the first embodiment, the tape 3
A hole 32 is formed in 1. Further, at a substantially central position of the hole 32 in the longitudinal direction of the tape-shaped body 31, at a predetermined position between the outer edge of the hole 32 and both side ends of the tape-shaped body 31,
A slit 35 is formed. The line of the slit 35 is formed so as to be in the longitudinal direction of the tape-shaped body 31. Here, the slit 35 can be formed simultaneously with punching of the hole 32.

Subsequently, a groove 33A having a V-shaped cross section is formed between the outer edge of the hole 32 and the slit 35 by drawing.
Thereby, the groove 33 in the width direction of the tape-shaped body 31 is formed.
The outside of A is a flat surface unlike the first embodiment. When viewed from the side of the carrier 30A, the space defined by the groove 33A and the flat surface of the tape-shaped body 31 has a size that allows the lead wire to easily enter. Next, the tongue piece 34 is bent as in the first embodiment. As described above, the carrier 30A is formed from the tape-shaped body 31. In the carrier 30A, a flat surface remains at both ends in the longitudinal direction of the tape-shaped body 31, and this flat surface serves as a guide portion of a roller when the carrier 30A is transferred, so that the carrier 30A can be easily transferred. Become.

Electrolytic capacitor lead wire carrier 30
The attachment to A can be performed in the same manner as in the first embodiment. That is, the tongue 34 is lifted, and the carrier 30A
May be inserted into the space defined by the flat surface of the tape-shaped body 31 and the groove 33A from the side surface of the tape-shaped body 31, and the lifting of the tongue-shaped piece 34 may be released. FIG. 7 is a plan view showing a state in which the lead wires 21 (the electrode terminals 20 are welded) are sequentially attached to the carrier 30A. In the second embodiment, the movement of the held lead wire 21 can be restrained by the flat surface outside the slit 35 in the width direction of the tape-shaped body 31 more than in the first embodiment. The lead wires 21 can be more effectively prevented from falling off.

The embodiment of the present invention has been described above. However, the present invention is not limited to the above-described embodiment, and various modifications can be made. For example, carrier 30,
The lead wire 21 welded to the electrode terminal 20 may be attached to 30A, or only the lead wire 21 may be attached first, and the electrode terminal 20 may be welded to the attached lead wire 21.

[0023]

According to the present invention, since the lead wire is arranged in a space much larger than the outer diameter of the lead wire, the work of mounting the lead wire on the carrier is simplified, and the work efficiency is improved. Can be planned. Furthermore, after the lead wire is arranged, the lead wire is held by the urging force of the groove and the tongue-shaped piece, so that the lead wire can be completely fixed to the carrier, and it is possible to prevent the lead wire from dropping off the carrier. it can.
