Abstract

PURPOSE:To prevent poor fusion by variably controlling the rotating force of a first heating roll by a second heating roll. CONSTITUTION:Plastic tapes 3, 4 are introduced into a heating fusing device 1 formed of paired heating rolls 5, 6 from the opposite directions, and conductors 2,..., 2 arranged in parallel to each other are guided so as to be vertically laid between the tapes 3, 4, and integrated therewith by heating and fusing. As the driving force is transmitted from the roll 5 to the roll 6 through an electromagnetic crack 60, the rotating speed difference between the rolls 5, 6 can be optionally set, and even if the kind and tension of the tapes 3, 4 are changed, the rotating speed difference can be controlled corresponding to this, so that the tapes 3, 4 are never wrinkled. Hence, a trouble of poor fusion can be prevented.

Description

Detailed Description of the Invention [Industrial Application Field] The present invention relates to a tape-like product in which a plurality of conductive wires are arranged in parallel in the longitudinal direction between two insulating tapes (plastic tapes) and are fused and fixed together. The present invention relates to a heat fusing device for tape-shaped electric wires used in the electric wire manufacturing process.

[Conventional technology] In recent years, with the development of electronic devices, electronic devices have become multifunctional.
Moreover, they tend to become smaller. As a result, electronic devices are becoming more densely packaged, and it is no longer possible to use conventional connector plugs, which take up a lot of space for wiring between each board. Thin and flexible tape-shaped electric wires, which are arranged and fixed together and have an exposed conductor part at the end thereof, have come to be widely used.

As shown in FIG. 2, this type of tape-shaped electric wire is constructed by guiding plastic chips 13 and 4 in opposite directions to a tape-shaped electric wire heating and fusing device 210 consisting of a pair of heating rolls 5 and 6. In addition, five conductors arranged in parallel @2.2. . . , 2 are guided vertically between the plastic tapes 3 and 4 as shown in the figure, and are heated and fused to form an integrated tape-like continuous body 20.

The heating roll 5 has a gear 52 and a pulley 54 on its shaft, and is driven by a drive motor 30 disposed adjacent to it as shown.

Further, the heating roll 6 has a gear 62 fitted to the gear 52 on its shaft portion, and is configured to receive driving force from the heating roll 5 as shown in the figure.
are designed to rotate in the directions of the arrows in the figure.

On the other hand, the heat fusing device 11 shown in FIG.
．． 6 is not provided with a Vj1 wheel or the like, and the driving force is transmitted from the heating roll 5 to the heating roll 6 by utilizing the pressure contact force (rubbing) between the heating roll 5 and the heating roll 6.

[Problems to be Solved by the Invention] In general, the plastic tape 3.4 is made of a thin, soft material, so during heat fusion, it may be affected by the strength of the pressing force or the difference in rotation between the heating rolls 5 and 6. , either of the plastic tapes 3 or 4 may be stretched, causing wrinkles or meandering in the plastic tapes 3 or 4, which may easily cause failures in heat fusion.

Therefore, in order to prevent such an accident, the heat fusing apparatus 10 shown in FIG. 2 has a gear 52.6 on the heating roll 5.6.
2 is installed so that they rotate synchronously, but since the rotation speed is fixed as -a by the gears 52 and 62, it is possible to adapt to changes in manufacturing conditions depending on the type of plastic tape 3.4 and the strength of tension. Therefore, it was not practical because it was not possible to set the i&appropriate rotation speed. On the other hand, the heat fusing device 1 shown in FIG.
No. 1 had the disadvantage that a difference in rotation was likely to occur due to slippage between the heating rolls 5 and 6.

[Object of the Invention] The present invention improves the disadvantages of the above-mentioned conventional example, and improves the production! f
'! - It is an object of the present invention to provide a heat fusing device for tape-shaped electric wires that can adjust the number of rotations of a heating roll to an optimum value.

[Means for Solving the Problems] Therefore, in the present invention, it rotates itself, and the first
a first heating roll provided with a gear; and a second heating roll provided with a second gear that comes into contact with the outer circumferential surface of the first heating roll and engages with the first gear at one end of the first heating roll. In the apparatus for heat fusing tape-like wires, the second heating roll is equipped with a rotation control means that can variably adjust the rotational force of the first heating roll. The aim is to achieve the above objectives.

[Example] Hereinafter, an example of a heat fusing apparatus for tape-shaped electric wires according to the present invention will be described based on FIG. 1.

Here, the same reference numerals are given to the same constituent members as in the above conventional example.

The tape-shaped electric wire heat-sealing device j11 shown in FIG. 1 includes a heating roll 5, a heating roll 6, and a drive motor 30.

As shown in the figure, the heating roll 5 includes a gear 52 and a pulley 54 on its shaft, and a drive motor 30 disposed adjacent to the shaft.
It's becoming more driven.

The heating roll 6 also has an electromagnetic clutch 60 as a rotation control means on the shaft portion, as shown in the figure.
The configuration includes a gear 62 directly connected to the primary side of 0.

This electromagnetic clutch 60 induces a magnetic force proportional to the driving force in the primary coil from a gear 62 that is fitted with the tooth TrL52 and receives the driving force, and variably controls the excitation current value of the secondary measurement coil. By doing so, the slippage between the primary coil and the secondary coil is adjusted, and the rotational speed of the heating roll 6 is adjusted to an optimum value in accordance with the type and tension of the plastic tape.

In order to manufacture the tape-shaped electric wire (tape-shaped continuous body) 20 using the tape-shaped electric wire heat-sealing apparatus 1 configured as described above, the above-mentioned conventional plastic tapes 3, 4
The heating rolls 5 are arranged in pairs in opposite directions.
．． 6 to the heating fusing device 1, and five conductive wires 2, 2.6 arranged in parallel. ...,
2 are guided vertically between the plastic tapes 3 and 4 as shown in the figure, and they are heat-fused and integrated. In this case, since the heating roll 6 receives the driving force from the heating roll 5 via the electromagnetic latch 60, the difference in rotation speed between the heating roll 5 and the heating roll 6 can be set arbitrarily. Even if the type or tension of the tape changes, the plastic tapes 3 and 4 can be adjusted accordingly to prevent wrinkles from forming.

[Effects of the Invention] The present invention is for manufacturing a tape-shaped electric wire using the above-described heating contact device for a tape-shaped electric wire, and in accordance with the manufacturing conditions,
It is possible to provide a practical heating fusing device for tape-shaped electric wires that can adjust the rotational speed of the heating roll to an optimum value and prevent accidents due to poor fusing.
