Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a wiring method by automatic wiring.

[0002]

2. Description of the Related Art As a conventional example of this kind of wiring material supply by automatic wiring, for example, a technique described in Japanese Patent Laid-Open No. 61-117899 is known. FIG. 6 shows a vertical cross section of a supply head according to this conventional example, and reference numerals 12 and 13 in the drawing denote straightening rollers for straightening the winding behavior of the wire material 14 in the horizontal and vertical directions. This allows
The winding curb removing work in the previous step of the wiring work is omitted, and the shape of the wire rod 14 after wiring is stabilized. In addition, in the wiring device, it is often the case that the end of the wiring material or the defective portion is found in the middle of wiring. In such a case, new wiring material is newly supplied or the defective portion is removed, I was laying the wire from the beginning.

[0003]

However, in the above-mentioned wiring method, when the terminal or defective portion of the wiring material is found in the middle of the wiring, the wiring up to that point must be interrupted, and However, there is a possibility that the wiring material having the defective portion may be directly wired. Therefore, in such a case, the wiring must be redone from the beginning, and there is a problem that workability is significantly reduced.

The present invention has been made in order to solve such a problem, and an object thereof is to provide a notice mark at a predetermined interval in front of the end or defective portion of the wiring material so that the wiring material may be provided in the middle of the wiring. Is to provide a wiring method capable of preventing the work from being redone by preventing the end of the wiring material or the defective portion from appearing.

[0005]

In order to solve the above-mentioned problems, the present invention provides a notice mark at the end of the wiring material or before the defective portion at a wiring length of one work. When the mark detecting sensor detects the advance notice mark, the wiring of the work is performed to the end, the wiring is completed, and the next wiring cannot be performed.

[0006]

According to the present invention, with the above construction, a notice mark is provided at the end of the wiring material or before the defective portion at a distance of the wiring length of one work, and the notice mark is provided by the wiring device. The notice mark detection sensor provided in the wire rod supply section detects that the wiring is completed until the end of the work, and after the wiring is completed, the termination or defective part of the wire rod will appear in the next wiring. At the same time, the next wiring work cannot be performed unless the wiring head is returned to the singular point (origin). As a result, the defective portion is not laid, and the end of the wiring material or the defective portion does not appear in the middle of the wiring.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT A preferred embodiment of the present invention will be described below with reference to the drawings. FIG. 1 is a diagram showing an outline of the wiring method of the present invention. In the figure, 1 is a wiring pin, 2 is a wiring pallet, and 3 is an X- that can freely travel on the wiring pallet 2.
Wiring heads 4 having a Y drive mechanism are sensors for detecting a notice mark. The sensor 4 uses a reflection type photoelectric switch in the embodiment, but may use an image processing device. Further, 6 is a case containing the wiring material 5, and A (inside the broken line) is an area for providing a notice mark when the end of the wiring material 5 or a defective portion is found. After finding, a notice mark is attached to the wire material 5 with the marking machine 8.

That is, when the sensor 7 detects the end of the wiring material 5 or a defective portion, a notice mark is provided on the wiring material 5 by the marking machine 8 installed at intervals of the length of one work. That is.

The wiring material 5 is pulled out from the case 6, passes through the area A, and is supplied through the notice mark detection sensor 4 and the wiring head 3, and the wiring head 3 is placed on the wiring pallet 2.
Is laid with a constant tension by running while hooking the wiring material on the wiring pin 1. At this time, the wiring pins 1 are arranged on the wiring pallet 2 along the wiring pattern, as shown in FIG.

In FIG. 3A, a notice mark 10 is provided in front of the defective portion 9 of the wiring material 5 with a space of a length of one work.
FIG. 3B shows an example in which the end 11 of the wire material 5 is provided.
In this example, the notice mark 10 is provided in front of, with a space corresponding to one work.

Next, the wiring method of this embodiment will be described with reference to the flow chart of FIG. Here, a series of flows from the start of wiring to the end of wiring will be referred to as a wiring step (see the broken line in FIG. 4). In step 30, the pallet is conveyed, and in step 32, it is determined whether wiring is started. If NO, the process proceeds to step 33, and if YES, the process proceeds to step 34. When the wiring is started, the wiring head 3 runs on the wiring pallet 2, and the wiring material 5 is pulled out from the case 6 to perform wiring. At this time, in step 34, if the terminal end 11 of the wiring material 5 or the defective portion 9 is not pulled out from the case 6, the process proceeds to step 36, and the notice mark 10 is detected.

If the notice mark 10 is not detected, in step 38, after finishing the wiring as it is, the wire rod end processing is performed and the wiring is started to the next wiring pallet. When the notice mark 10 is detected in step 36,
In step 40, the wiring process at that time is performed until the wiring process is completed, but at the same time the next wiring process is prevented from moving, and at the same time, the terminal or defective portion of the wiring material 5 appears during the next wiring process. Let us know. Then, the wiring material is replaced or the defective portion is removed, and in step 42,
When the wiring head 3 is once returned to the singular point (origin) P1 in FIG. 2 and then the wiring device is reset, the wiring becomes possible.

FIG. 5 shows a flow chart of the marking process for the wiring material. That is, when the wiring material is supplied in step 50, the wiring material 5 is supplied in step 52.
Judge whether the end of the
If the result is ES, the process proceeds to step 54, where the notice mark 10 is applied to the end of the wiring material 5 or a defective portion and a length of one work. If NO in step 52, the advancement mark 10 is not applied and the process proceeds to the next wiring process.

[0014]

As described above, according to the present invention, the notice mark is provided at the end of the wiring material or in front of the defective portion at a distance of the wiring length for one work, and the sensor for detecting the mark is provided. When the notice mark is detected, the wiring of the work is performed to the end, the wiring is completed, and the next wiring cannot be performed. Can be prevented and the work can be prevented from being redone.
