DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method for winding a wire in an electronic component such as a coil product.

[0002]

2. Description of the Related Art FIG. 1 shows a coil product formed by winding a wire 2 around a work 1. FIG. With reference to FIG.
And 6 are provided, and the end 3 of the wire 2 is connected to the electrode terminal 5, and the end 4 of the wire 2 is connected to the electrode terminal 6. Conventionally, such a coil product is shown in FIG.
It is manufactured by the method shown in FIG. Referring to FIG.
The end 3 of the wire 2 is passed through the nozzle 8 held by the nozzle holder 7, and the tip 3 a of the end 3 of the wire is attached to the electrode terminal 5 provided on the outer surface of the collar of the work 1. Have been.

In the conventional method, the end 3 of the wire rod to which the tip 3a is fixed is hooked on the collar at the upper end of the work 1 by moving the nozzle 8 in three directions of X, Y and Z, and thereafter the work 1 is wound. The wire 2 was wound around the work 1 by rotating in the direction.

[0004]

However, in these conventional methods, it is necessary to move the nozzle 8 in three directions of X, Y and Z. For this reason, the software for controlling the movement of the nozzle becomes considerably expensive, and a long time is required until the step of hooking the wire end is completed, which is not preferable in terms of production efficiency. there were. In addition, when the distance between the flanges at the ends of the work is small, or when the work itself is small, the movement of the nozzle and the nozzle holder is restricted, so that the work of hooking the wire end to the work becomes difficult. There was also the problem of becoming.

SUMMARY OF THE INVENTION It is an object of the present invention to provide a highly accurate and efficient electronic component without being limited by the size and shape of the electronic component.
An object of the present invention is to provide a method capable of winding a wire at low cost.

[0006]

According to the wire winding method of the present invention, an end of the wire is hooked on an electronic component having a wound portion on which the wire is to be wound and flanges provided at both ends of the wound portion. Then, a method of winding the wire around the winding part of the electronic component, in which the end of the end of the wire is fixed to the outer surface of the collar of the electronic component, and the end of the wire is guided by the guide member. It is characterized by comprising a step of pressing against the center side of the winding portion, and a step of hooking the end of the wire rod pressed by the guide member to the brim portion of the electronic component by rotating the electronic component in the winding direction. .

FIG. 3 is a side view for explaining an example of the method according to the present invention. Referring to FIG. 3A, a work 11 as an electronic component is configured by providing collar portions 11b and 11c at both ends of a winding portion 11a. The wound wire is passed through a nozzle 18, and first, a tip 13 a of a wire end 13 is fixed to a flange 11 b. Next, referring to FIG. 3B, a thin plate material 19 is used as a guide member, and the wire material end 13 is pressed against the center of the winding portion 11a by the plate material 19.

Next, referring to FIG. 3 (c), in this state, the work 11 is rotated half a turn as indicated by an arrow A to
3 is hooked on the collar 11b. The guide member used in the present invention is not limited to the above-mentioned plate member, but may be a member having another shape such as a rod-shaped or linear member.

[0009]

According to the present invention, the end of the wire is rotated in the winding direction while the end of the wire is pressed against the center of the winding of the electronic component by the guide member, so that the end of the wire is joined to the flange of the electronic component. I'm hooked on. For this reason, the end of the wire can be hooked on the flange of the electronic component without performing complicated movement of the nozzle as in the related art. Further, since there is no need to move the nozzle and the nozzle holder, there is no restriction due to such movement. Therefore, the wire can be wound even when the distance between the flanges is small or when the electronic component is small. Further, since the complicated movement of the nozzle and the nozzle holder as in the related art is not required, the completion time of the operation is shortened. Further, the wire can be wound at low cost.

[0010]

4 to 7 show a method of winding a wire in an embodiment according to the present invention. Referring to FIG. 4, in this embodiment, first, the tip 13 a of the wire rod end portion 13 is
It is attached and fixed to the electrode terminal 15 of the one flange portion 11b by crimping or the like. The wire is supplied through a nozzle 18. FIG.
4, the nozzle 18 is set at a position substantially at the center of the winding portion 11a of the workpiece 11 in the state of FIG.

Referring to FIG. 6, next, a thin plate material such as a thickness tape is lowered at a position as close to the work 11 as possible, and the wire end 13 is pressed to a position substantially at the center of the winding portion 11a of the work. This state is similar to the state shown in FIG. FIG. 9 is a cross-sectional view of the thickness tape used in this embodiment. This thickness tape has a length of 30 mm, a width of 12.7 mm and a thickness of 0.2 mm. As shown in FIG. 9, in this embodiment, an end face 19a that is in contact with the end of the wire rod is finished to a smooth R surface. FIG. 10 is a plan view showing the thickness tape. Referring to FIG. 10, thickness tape 1
9 have longitudinal holes 19 for attachment to the machine.
b and 19c are formed.

The material of the thickness tape used in this embodiment is stainless steel. In this embodiment, a thickness tape is used as a guide member. However, the guide member used in the present invention is not necessarily limited to the thickness tape, but may be any type as long as the end of the wire can be pressed. May be. Thickness tape is
Since it is plate-shaped, it can be easily attached to a machine and has durability, so that it is particularly preferable as the guide member of the present invention.

Referring to FIG. 7, as shown in FIG.
The work 11 is held in a state where the wire end 13 is pressed at 9.
Is rotated in the winding direction. Due to the rotation of the work 11, the wire rod end 13 is hooked on the collar 11b. After hooking the wire end 13 on the collar 11b in this manner,
The plate material 19 is lifted and removed, and thereafter, the work 11 is rotated in accordance with a normal method to wind the wire around the winding portion 11a of the work 11. As described above, in this embodiment, the end of the wire rod is pressed by the plate member 19, and the work 1
The end of the wire is hooked by rotating 1.
For this reason, the complicated movement of the nozzle as in the related art is not required, and the end of the wire can be easily hooked in a short time. In addition, there is no longer any restriction on the size and shape of the work as in the related art. A groove 11d as shown in FIG. 8 may be formed in the collar portion 11b to more securely hook the end of the wire.

[0014]

According to the wire winding method of the present invention, the end of the wire is hooked on the flange of the electronic component by rotating the electronic component in the winding direction while pressing the end of the wire by the guide member. ing. For this reason, complicated movement of the nozzle and the nozzle holder as in the related art becomes unnecessary,
The hooking operation can be completed easily and in a short time. Therefore, the wire can be efficiently wound at a lower cost than before.

Further, since a complicated mechanism for moving the nozzle is not required, a large space as in the prior art is not required. Further, since there is no movement of the nozzle and the nozzle holder as in the related art, there is no restriction due to the size and shape of the target electronic component. For this reason, a wire can be wound on electronic components of various sizes and shapes using the same device.
