Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a circuit body laminating apparatus for aligning two insulating sheets sandwiching a conducting wire without misalignment.

[0002]

2. Description of the Related Art FIG. 5 shows a conventional circuit body laminating apparatus. The device 25 includes a pair of heat rollers 27 having elastic bodies 26 attached to the surface thereof, and a drive mechanism (not shown) for rotating the rollers 27. A heater (not shown) is incorporated inside the roller 27. The roller 2
7 between the two strip-shaped insulating sheet 28,2 made of synthetic resin
9 and a plurality of conductors 14 between the sheets 28 and 29.
And are supplied at the same time.

Each insulating sheet 28, 29 is provided with a connection hole 11 in advance at the same position corresponding thereto. The connection hole 11 is for exposing the conductive wire 14 and connecting it with another circuit body (not shown). Also each sheet 2
A thermoplastic adhesive is applied in advance to the inner surfaces of 8 and 29, and the insulating sheets 28 and 29 and the conductor 14 are sandwiched between a pair of heat rollers 27, heated, and adhered to each other.

[0004]

However, in the conventional apparatus, when the two insulating sheets 28 and 29 are adhered by the heat roller 27, there is a difference in tension applied to the sheets 28 and 29. For that reason, the positions of the connection holes 11 of both sheets 28 and 29 are displaced, and the exposed conductor 1 in the connection holes 11 is displaced.
There was a problem that the connectivity to 4 deteriorated. The present invention has been made in view of the above points, and an object thereof is to provide a circuit body laminating apparatus capable of preventing the positional displacement of the connection holes when adhering two insulating sheets.

[0005]

In order to achieve the above object, the present invention provides a two-row insulating sheet having a connection hole through which a conductor can be exposed, and a plurality of conducting wires arranged between the insulating sheets. In a circuit body laminating apparatus in which a pair of heat rollers are adhered to each other, a plurality of positioning holes are formed at equal pitches in the two insulating sheets, and the rigid roller of the heat roller is composed of an elastic roller and a rigid roller. It is based on a structure in which a plurality of guide protrusions for the positioning holes are provided on the outer peripheral portion. It is also possible to set the protruding length of the guide projection to be twice or more the plate thickness of one insulating sheet.

[0006]

The positioning holes of the two insulating sheets are engaged with the guide projections of the rigid roller in a state where the two insulating sheets are overlapped with each other or immediately before they are overlapped with each other. The engagement between the guide protrusion and the positioning hole is performed just before the two insulating sheets are laminated by the heat roller. Then, the two insulating sheets are heat-bonded with the positioning holes aligned with each other, that is, with the connection holes of each sheet aligned. The tip of the guide protrusion can bite into the elastic roller, which allows the elastic roller to press the sheet.

[0007]

1 and 2 show an embodiment of a circuit body laminating apparatus according to the present invention. This device 1 uses, as a heat roller 4, an elastic roller 2 having an elastic body 5 such as silicon rubber adhered to the surface thereof and a rigid roller 3 made of iron or the like for the elastic roller 2, and both sides of the rigid roller 3 are used. A plurality of guide protrusions 9 for the positioning holes 8 of the upper and lower insulating sheets 6 and 7 are provided on the circumference of the portion.

The positioning hole 8 has a hole making machine 10 which will be described later.
At the same time with the two insulation sheets 6 and 7 stacked,
Or, the sheets 6 and 7 are separately punched in a circular shape at equal pitches by another punching means (not shown). The pitch P of the positioning holes 8 is set to be smaller than the interval (not necessarily constant) of the connection holes 11 formed in the sheets 6 and 7 in advance. The positioning holes 8 are formed at the same position (on the same line) in the sheet width direction on both sides of the insulating sheets 6 and 7, and are also formed on the same line in the sheet longitudinal direction.

A guide protrusion 9 fitted in the positioning hole 8
As shown in FIG. 3, they are provided on both sides of the rigid roller 3 in the circumferential direction at the same pitch as the pitch P of the positioning holes 8. As shown in the enlarged view of FIG. 2, each guide protrusion 9 has, for example, a cylindrical pin 9 ′ made of iron and a pin hole 12 of the rigid roller 3.
It is provided by driving into. The protrusion length L of the pin 9'from the roller 3, that is, the guide protrusion 9 is set to about 2.5 times the plate thickness of one insulating sheet 6 to 7, and the diameter of the guide protrusion 9 is equal to or slightly larger than the inner diameter of the positioning hole 8. It is set small.

The guide protrusions 9 are provided on both sides of the rigid roller 3 so as to be aligned on the same line in the roller circumferential direction and at the same position (on the same line) in the roller axial direction. Although the tip end surface of the guide protrusion 9 is formed flat in this example, it may be curved according to the curvature of the rigid roller 3. A rod-shaped heater 13 is provided inside each of the rollers 2 and 3, and the sheets 6 and 7 are adhered to the inner surface of each of the sheets 6 and 7 with a thermoplastic adhesive previously attached to the conductive wire 14 sandwiched between the sheets. To be done.

As shown in FIG. 2, the guide projection 9 is formed by the rollers 2, 3
Engages with the positioning holes 8 immediately before laminating the insulating sheets 6 and 7, and aligns the sheets 6 and 7. As a result, as shown in FIG. 1, when the two sheets 6 and 7 are joined, the positions of the connection holes 11 of the respective sheets are aligned, and the conductive wire 1 is inserted into the circular connection hole 11.
4 is definitely exposed.

FIG. 4 shows an example of a flat circuit body manufacturing apparatus 15 including the circuit body laminating apparatus 1.
The manufacturing apparatus 15 has already been proposed separately from this case.
The laminating apparatus 1 is located substantially at the center of the circuit body manufacturing apparatus 15, and the lower rigid roller 3 is chain driven (17) by the drive motor 16. The upper elastic roller 2 is synchronously rotated in the opposite direction to the rigid roller 3 via a gear (not shown).

At the rear of the laminating apparatus 1, a pull-out roller 18 which is also chain-driven by a motor 16 is located. The draw-out roller 18 rotates at a slightly higher speed than the heat rollers 2 and 3, and straightens the flat circuit body 19 in which the insulating sheets 6 and 7 and the conductive wire 14 are laminated. The insulating sheets 6 and 7 are separately supplied from above and below between the heat rollers 2 and 3, and a plurality of conducting wires 14 are supplied from the side between the both sheets 6 and 7.

Before being separated by the pair of separating rollers 20, the sheets 6 and 7 are superposed by the guide rollers 21 and introduced into the punching machine 10. The punching machine 10 has a punching pin 22 for connecting holes and a punching pin (not shown) for positioning holes.
Are provided respectively, and the connection hole 11 and the positioning hole 8 can be formed at the same time.

[0015]

As described above, according to the present invention, since the guide projections of the rigid roller and the positioning holes of the insulating sheet are engaged with each other, the two insulating sheets are adhered to each other without displacement of the connecting holes. The conductor is surely exposed in the connection hole, and reliable connection with the counterpart circuit body or the like becomes possible. Even if the protruding length of the guide protrusion is set to be twice or more that of the insulating sheet, the elastic roller absorbs the protruding length of the guide protrusion, so that the engagement between the guide protrusion and the positioning hole becomes more reliable, and the elastic roller The insulating sheet is surely pressed by, and the adhesiveness of the sheet is not impaired.
