Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a wire laying head for a wire conductor in a wire laying apparatus used when wire laying a wire conductor on a wire laying surface such as a film.

[0002]

2. Description of the Related Art A flat cable in which a conductor pattern is sandwiched between two films is usually formed by laying a linear conductor on a base film to form a predetermined conductor pattern and then covering the same with a cover. Lay films are laminated to form a laminate film in which the conductor pattern is sandwiched, and the laminate film is manufactured by cutting the laminate film into a predetermined shape including the conductor pattern. For the work, as shown in FIG. 7, a conductor wiring device 50 provided with a wiring head 52 that two-dimensionally moves in the X direction and the Y direction on an installation surface 51 of a base film having an adhesive layer on the upper surface is used. Is done.

The wiring head 52 is shown in FIG.
As shown in (b), a head body 54 is integrally formed at the lower end of the support portion 53, and a conductor that guides the linear conductor to the conductor pressing portion at the lower end is formed on the head body 54. A guide groove 55 is formed.

As shown in detail in FIGS. 9 and 10, the head main body 54 is a substantially cylindrical metal block having a conical portion 54a at the tip thereof, and the conical portion 54a extends upward from the vicinity of the center point of the tip. The left half of the drawing has a cutout portion 54b that is hollowed out in a spherical shape. Then, from the right side of the peripheral edge of the remaining conical portion 54a toward the center point, the width thereof is tapered, and the depth thereof is gradually reduced so that the distal end edge 54c of the cutout portion 54b.
A conductor guide groove 55 that disappears at is formed.

The wiring head 52 constructed as described above
11, the linear conductor A is drawn out from the tip end side along the conductor guide groove 55, and the drawn linear conductor A disappears in the conductor guide groove 55, as shown in FIG. 54b of the tip edge 54c as the conductor pressing portion,
The linear conductor A can be attached to the wiring surface B by moving the entire wiring head 52 on the wiring surface B while pressing the wiring surface B which is the adhesive surface of the base film. You can do it.

[0006]

However, in the wiring head 52 as described above, the linear conductor pressing portion (tip edge 54) is used.
Since the linear conductor A is pressed against the wiring surface B by c), there is a problem that the pressing area is very small and the linear conductor A cannot be sufficiently attached to the wiring surface B. is there.

Further, since the depth of the conductor guide groove 55 becomes gradually shallower toward the tip thereof and the groove disappears in the conductor pressing portion, a linear shape along the conductor guide groove 55 is formed. There is also a problem that the conductor A is easily detached from the conductor guide groove 55 on the tip side thereof.

SUMMARY OF THE INVENTION Therefore, an object of the present invention is to provide a wire laying head for wire conductors, which can secure a sufficient adhesive force of the wire conductors to the wire laying surface and which is difficult for the set wire conductors to come off. .

[0009]

In order to solve the above-mentioned problems, the present invention has a conductor guide groove for guiding a linear conductor to a conductor pressing portion at the lower end, and a linear wire fed from the tip of the conductor guide groove. In the wiring head of the linear conductor for laying the linear conductor by moving the conductor while pressing the conductor against the wiring surface by the conductor pressing portion, the conductor pressing portion is provided with the open end of the conductor guide groove. It is formed by a flat pressing surface including.

It is preferable that the pressing surface is formed in a circular shape, and the pressing surface and the conductor guide groove are coated with a material having a small frictional resistance with the conductor.

More preferably, it is formed by the roller surface of the guide roller provided at the boundary between the guide groove and the pressing surface.

Further, a conductor pressing spring for pressing the linear conductor passing through the conductor guide groove toward the conductor guide groove is provided so as to cross the conductor guide groove, and the conductor pressing groove is provided on the surface where the conductor guide groove is formed. An accommodating groove shallower than the conductor guide groove into which the spring fits may be formed.

[0013]

In the wire-laying head of the linear conductor configured as described above, since the conductor pressing portion is formed by the flat pressing surface including the open end of the conductor guide groove, the pressing area of the linear conductor is reduced. The size of the conductor guide groove is increased, and the depth of the conductor guide groove near the conductor pressing portion is sufficiently secured.

Further, in the case where the pressing surface is formed in a circular shape, the linear conductor is uniformly pressed even when the wiring head is rotated when the wiring is performed while bending the linear conductor.

Further, in the case where the conductor guide groove and the pressing surface are coated with a material having a small frictional resistance with the conductor, the linear conductor is smoothly fed in the conductor guide groove and the pressing surface. .

A curved surface connecting the bottom surface of the conductor guide groove and the pressing surface is formed at the boundary portion between the conductor guide groove and the pressing surface, or the curved surface is formed by the roller surface of the guide roller. In the case of the formed one, the feeding of the linear conductor from the conductor guide groove to the pressing surface is smoothly performed.

Particularly, in the case where the conductor pressing spring and the accommodation groove into which the conductor pressing spring is fitted are formed, the depth of the conductor guide groove in the vicinity of the conductor pressing portion is sufficiently secured, Can secure a sufficient depth of the accommodation groove,
Even if the conductor pressing spring is arranged in the vicinity of the conductor pressing portion, the conductor pressing spring does not project and does not hinder the wiring.
