Description

[Detailed Description of the Invention] Background and Objectives of the Invention When tape-shaped electric wires are used to connect electronic devices, conventionally, a connector plug is connected to the terminal end of the tape-shaped electric wire, and the wire is inserted into a socket.

Recently, people have begun to use plugs instead of using plugs, instead using the ends of tape-shaped wires themselves.

That is, the end of the tape-shaped electric wire is exposed and inserted directly into the socket, and the conductor functions as a contact.
However, in that case, the tape-shaped electric wire itself is too thin and lacks strength when inserted.

Therefore, a tape electric wire as shown in "Fig. 6" has been proposed (Utility Model Application No. 53-97392). This is done by sandwiching and gluing the conductor 10 with two pieces of polyester tape 12, etc. to make a regular long tape wire, cutting it to an appropriate length (Fig. 1), and cutting only one side of each end. Peel off the skin (Figure 8), then add a reinforcing layer 3 such as polyester to both ends.
60.362 is attached. In the above publication,
As for the manufacturing method, it is stated that the ends are stripped using a commercially available stripper, and that the reinforcing layer 360 and the like are lined with an adhesive.

Therefore, at this stage, it seems that they were made by hand. Naturally, in order to commercialize this tape electric wire, it must be mechanized and produced in large quantities, but so far nothing has been announced regarding the manufacturing method.

By the way, in the above-mentioned tape electric wire, the adhesive force between the conductor 10 and the insulating tape 12 is weak, and as the tape is repeatedly connected to and removed from the socket, the gap between them may become separated.

For this purpose, as shown in "Figure 1", the insulating tape 12 on both ends
A tape electric wire has been proposed in which both sides of the reinforcing layers 360 and 362 are peeled off and the reinforcing layers 360 and 362 are attached using a strong adhesive.

The present invention relates to a method of manufacturing such a tape-shaped electric wire with terminals treated.

Example This method consists of the following steps (see FIG. 2).

1) Step of superimposing tape 12 with windows 16 on both sides of conductor 10.

2) A step of fusing the conductor 10 and tape 12.

3) A step of fusing the reinforcing tape 36, which is the basis of the reinforcing layer 360, etc., onto the window 16.

4) Process of cutting at the center of the window 16 to make the product.

The explanation will be given below in this order. (1) Step of layering window tape on both sides of the conductor [Fig. 2] In the step, 10 is the conductor.

Those with a round or rectangular cross section are used. These are arranged in parallel at equal intervals and sent out in succession. 12A and 12B are plastic tapes.

It is continuously sent out from both the upper and lower sides of the conductor 10. The material is polyester glued with thermoplastic adhesive, etc.
A material having a thickness of about 50 to 100 μm is used. Rectangular windows 16A, 16 are formed in opposing positions at predetermined intervals by known drilling devices 14A, 14B, respectively.
B is vacant. 18 is a guide roll.

Thereby, the tapes 12A and 12B are overlapped on both the upper and lower sides of the conductor 10.

At this time, the positions of both windows 16A and 16B are made to match tightly. (2) The conductor and tape fusing step 20 is performed using an attraction roll.

This allows conductor 10 and tape 12A. B and are fused together. Through the above steps, a continuous body 100 of tape-shaped electric wires is produced in which windows 16 are provided at predetermined intervals and conductors 10 are exposed at the windows 16.

Note that the steps up to this point are known (for example, Japanese Patent Application Laid-open No. 5
1-71979). 22 is an accumulator, 24 and 26 are its fixed position rolls, 28 is a feed roll, and 30 is an upper and lower roll.

(3) Fusion process of reinforcing tape 36 1) Description of the equipment used in this part.

32 is a moving table.

It can be moved by wheels 33 on rails 34 parallel to the flow of continuous body 100 .

36 is a reinforcing tape.

It becomes the source of the reinforcing layer 360 and the like.

The material is polyester bonded with an adhesive, and the thickness is about 100 to 250 μm. Further, the width A is appropriately wider than the width B of the window 16. 37 is a supply roll thereof, which is provided on the movable table 32.

38 is a feed roll that feeds the reinforcing tape 36 in a direction perpendicular to the continuous body 100.

Note that the reinforcing tape 36 is a thin plastic tape, so when it is fed out in a cantilevered manner, the tip will sag. Therefore, the leading end of the reinforcing tape 36 is supported and placed on the continuous body 100 by a suitable means such as a guide plate or a suction cup using a vacuum (not shown). 40 is a tape tip detector.

For example, it consists of a limit switch, etc., and has a continuum of 100
A continuous body 1 is placed at a position facing the reinforcing tape 36 across the
It is provided at a position adjacent to 00.

Then, it is detected that the leading end of the reinforcing tape 36, which is being fed while sliding on the continuous body 100, has reached the edge of the continuous body 100. 42 is a support.

Two on each side of the continuum 100, a total of four moving platforms 32
stand upright on top of

43 is a fusion block.

This is for fusing the reinforcing tape 36 to the continuous body 100, and consists of a hot plate 44 and a lower die 46.

Both of these are guided at their four corners by the pillars 42, and are moved up and down by, for example, an air cylinder (not shown). In addition, convex portions 44 are provided at the portions that correspond to the windows 16.
0,460 (Figure 3). Further, a cutter 48 is attached to the hot plate 44. 50 is a gripping device.

For example, air cylinders 52 are provided at opposite positions across the continuum 100, and a pad 54 is attached to the tip of the air cylinders 52.

Note that the upper cylinder 52 is supported by a bracket 56 protruding from the column 42. The lower cylinder 52 is placed upright on the movable table 32. When a signal is input from the outside, the cylinder 52 operates and the pad 54 grips the continuous body 100.

Then, the fusing block 43 and the supply roll 37 are moved to the moving table 3.
2 and moves at the same speed as the continuum 100. 57 is a return means for the movable table 32.

For example, a single-acting air cylinder 52 or the like is used.

The rod is attached to the moving table 32 and is operated only when returning the moving table 32. 58 is a window detector.

This is to detect that the window 16 has come to the exact side of the reinforcing tape 36 as the continuous body 100 has progressed.

Any known sensor (contact type, optical type, pneumatic type, etc.) can be used. Its mounting position may be, for example, fusion block 4.
Window 1 to be fused so as not to interfere with window 3 etc.
Place it on the window 16 one or two places in front of 6. 2) Explanation of operation.

As the continuum 100 advances as described above, when the window 16 comes right next to the reinforcing tape 36, the window detector 58 is activated.

Then, the gripping device 50 operates to grip the continuous body 100, and the movable table 32 moves together with the continuous body 100.

At the same time, the feed roll 38 rotates and the reinforcing tape 36
send out.

The reinforcing tape 36 slides over the continuum 100 and closes the window 16.
cover up.

Then, when the leading end contacts the tape leading end detector 40, it stops.

Then, the fusing block 43 operates.

The hot plate 44 moves downward and the lower die 46 moves upward, respectively, to fuse the reinforcing tape 36 to the continuous body 100. At the same time Katsuta 4
8 cuts the tape 36 at the edge line of the continuous body 100.
When the hot plate 44 and the lower die 46 return after the fusion is completed, the gripping device 50 also returns at the same time to release the continuous body 100.

Then, the return means 57 operates to return the movable table 32 to the place where it was initially waiting.

3) Repeat this to attach the reinforcing tape 36 on the window 16.
A continuous body 100 is made by gluing
Wind it to 0.

(4) Cutting the continuous body 100.

Once the continuous body of tape-shaped electric wire 100 is wound up as described above, it is sent out again and cut along the center lines 62 and 64 of the adjacent windows 16, as shown in "Fig. 3".

i Then, the reinforcing tape 36 is also divided into two parts and the reinforcing layers 360, 3
Becomes 62.

In this way, a tape-shaped electric wire 200 whose terminals have been treated is produced.
If you invert what is shown in Figure 3, it will look like Figure 1.

(5) Note that the continuous body 100 of the tape-shaped electric wire may be immediately cut along the center lines 62 and 64 of the window 16 without being wound around the take-up roll 60.

(6) When the reinforcing tape 36 is fused to every other window 16 as shown in [Fig. 4], the end-treated tape-shaped electric wire becomes like 201 in the same figure.

(7) As shown in [Fig. 5], when the reinforcing tape 36 is fused top and bottom alternately, the end-treated tape-shaped electric wire 20
It will be like 2. Effects of the Invention In the conventionally known process of making a continuum of tape-like electric wires with windows, a reinforcing tape with a width wider than the window is added to either the upper or lower surface of the continuum of tape-like electric wires. Since the process of fusing at a position that covers the window and the process of cutting the continuous tape-shaped electric wire at the center line of the adjacent window are combined, (1) with code 200; Tape-shaped electric wires as shown can be automatically and continuously produced.

(2) By changing the pasting position of the reinforcing tape,
Tape-shaped electric wire 201 (FIG. 4) and tape-shaped electric wire 202
A structure like the one shown in FIG. 5 can be easily made.
