[Detailed description of the invention]

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a holding jig for holding a wire in a step of cutting the wire after winding the wire around a bobbin of a coil.

[0002]

2. Description of the Related Art As shown in FIG. 4, in order to manufacture a coil 3 in which a very fine wire 2 is wound around a bobbin 1 in a multiple manner, one end of the wire 2 is fixed to an end of the bobbin 1 by means such as heat welding. Thereafter, the bobbin 1 is rotated to wind the wire 2 around the outer periphery thereof, and after winding, the wire 2 is cut by holding the wire 2 in the middle by a holding device, and the cut end is fixed to the bobbin 1. I have.

FIG. 5 shows a holding device for holding the wire in the wire cutting step, and a pair of holding jigs 5 and 5 facing both lower sides of the head portion 4.
The holding jigs 5 and 5 are moved toward and away from each other by, for example, an air cylinder, and the approaching movement of the holding jigs 5 and 5 holds the wire between the opposing surfaces. I have.

Conventionally, the holding jigs 5, 5 used in the above-described holding apparatus have thicknesses on opposite surfaces of a jig body 6 made of steel, as shown in FIGS. 0.5-1.0mm
A degree of silicone rubber 7 is adhered with an adhesive, and the wire 2 is sandwiched and held from both sides by utilizing the friction coefficient and elasticity of the opposed silicone rubber 7.

[0005]

When the wire 2 is directly sandwiched between the silicon rubbers 7, the silicon rubber 7 is worn, the holding surface is recessed, and when the wire 2 is sandwiched, the silicon rubbers 7 are mutually engaged. Therefore, when the holding jigs 5 and 5 are separated from each other, one silicon rubber 7 may be suddenly peeled off from the jig main body 6 and fall off.

[0006] Therefore, there is a problem that the holding of the wire becomes uncertain, a wire cut mistake or a drop of a discarded wire occurs, and the non-defective product rate, the operation rate, and the workability of coil production are reduced.

[0007] In order to solve the above-mentioned problems, the present invention uses a rigid body for the holding portion of the wire, does not cause abrasion or falling off, and improves the yield rate, operation rate and workability of coil production. It is an object of the present invention to provide a wire holding jig that can be made to work.

[0008]

Means for Solving the Problems] To solve the above problems, this invention has the opposed surfaces of the jig body, adopts the configuration in which the rigid body for holding the wire attached via a rubber Things.

[0009]

[Function] The jig body holds and holds the wire with a rigid body by the approaching movement of the jig body. The rigid body is attached to the jig body via rubber , so the wire can be elastically sandwiched and the wire of any diameter In addition to the use of a rigid body, there is no wear due to the wire, and the durability is improved.

Further, the rigid bodies do not adhere to each other when the wires are sandwiched, and there is no peeling or falling.

[0011]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described below with reference to FIGS.

As shown in the figure, a wire holding jig 11 opposed to both sides is composed of a hard jig main body 12 and a rigid body 14 attached to mutually facing surfaces of the jig main body 12 via an elastic body 13. When the two holding jigs 11 move close to each other, the wire 2 is sandwiched between the rigid bodies 14, and the elastic body 13 elastically holds the wire.

The jig body 12 is formed using various metals, acrylic plates, and the like. In the case shown in the figure, a concave portion 15 slightly larger than the rigid body 14 is provided on the surface on which the rigid body 14 is mounted.

[0014] filled with the elastic member 13 made of rubber such as silicone rubber as the recess 15 FIG. 2 (A), the Paste rigid 14 on the surface of the elastic body 13, as the Couto 2 (B), the bullet
By cutting off the surrounding part of the sexual body 13 to which the rigid body 14 is not bonded, the elastic body 13 has an elastic function by securing the surrounding space.

The rigid body 14 is made of stainless steel, various metal plates, an acrylic plate or the like, and the elastic body 13 can be made of not only silicon rubber but also other rubbers .

The jig body 12 has a rectangular shape having a notch 16 from the upper part in the middle, and a rigid body 14 attached to both sides of the notch 16 via an elastic body 13. However, the shape of the jig body 12 and the number of rigid bodies 14 to be attached may be freely selected.

The holding jig of the present invention has the above-described configuration, and both holding jigs 1 are provided in the same manner as the holding device shown in FIG.
1 are arranged so as to freely move toward and away from each other, and after the coil is wound around the bobbin, both holding jigs 11 are moved close to each other, and the wire is held by holding the wire between the opposed rigid bodies 14 as shown in FIG. Is performed.

The rigid body 14 directly hit by the wire is hardly worn by the wire 2 and has improved durability.
Due to the elasticity of the elastic body 13, the rigid body 14 elastically sandwiches the wire 2 and can securely hold the wire 2.

Moreover, the rigid body 14 does not adhere to each other when the wire 2 is sandwiched, and it is possible to prevent a trouble such as peeling off.

[0020]

[Effects of the Invention] As described above, according to the present invention, the rigid body is attached to the jig body via the rubber , so that the rigid body does not wear due to the wire, the durability is improved, the replacement frequency is reduced, and the operation is performed. In addition to improving the rate, the wire can be securely held, so that wire cutting mistakes and discarded drops can be prevented, and the yield rate of the coil is improved, and workability is improved.

Further, the elasticity of the rubber makes it possible to cope with holding wires of all diameters, and since the wires are sandwiched between rigid bodies, there is no possibility that they adhere to each other, and the rigid bodies do not peel off. The occurrence of unexpected defective products and mechanical troubles can be prevented, and the rate of non-defective products and the operating rate of coil manufacturing can be improved.
