Description

[Detailed Description of the Invention] The present invention determines whether or not a plurality of electric wires connected to a connector in a predetermined color arrangement order are actually connected in a predetermined color arrangement order. Regarding the method.

As is well known, colored wires, such as red, colored, yellow, etc., are connected to each terminal of the connector by hand.
It is necessary to inspect the parts thus obtained to see if they are connected in the correct color arrangement.

However, conventional inspections rely only on visual discrimination by the operator, and as a result, the worker not only has to put in a lot of effort, but also spends a considerable amount of time on the discrimination.
Not only is it inefficient, but especially when there are a large number of wires, color classification tends to lead to inaccurate judgments, and satisfactory results have not been obtained regarding the reliability of the product.

In view of these conventional problems, the present invention makes full use of optical color filters, line sensor cameras, computers, etc., to automatically and highly reliable correct and incorrect information by simply holding the test object in a predetermined state. It is intended to enable discrimination, and its characteristics are that the wire connection arrangement of several wires connected to a connector is determined by visual inspection. The light irradiated onto the wire or the light reflected from the wire is transmitted through optical color filters of the three primary colors of red, evening, and green in the desired order. This transmitted light is received by a line sensor camera, and the video signal from the camera is converted into an analog-to-digital signal by a CombiCo-Coo video converter, and this is converted into the master color array. The color arrangement of the above-mentioned test object is stored in the computer, and then the color arrangement of the above-mentioned test object is determined by the computer by performing the same procedure as the master described in 2. The method is to obtain a measurement result and compare the 1llll+detection result with the color arrangement stored in the master.

To explain the present invention in detail with reference to the drawings, as shown in FIG.
are extended from the connecting side 1' in an aligned state,
First, visually check only one of these parts, pick up the one (master) with the correct color arrangement of the electric wires 2.2, etc., and align the electric wires at a predetermined pitch.
In the embodiment of the same figure, the lamp 3 is held by means as described below.
A light beam t is irradiated onto the electric wire 2.2...φ.

And due to this, the reflected light l! from the electric wires 2.2... , 2 are directed toward the line sensor camera 4, but in this embodiment, the electric wires 2.2--
An optical color filter 5 is interposed between the --@ and the line sensor camera 4.

In the filter 5 exemplified above, the disk-shaped rotary plate 6 is separated by radial dividing lines 7, 7', 7'' to divide the three primary colors of red, blue, and green into filters R, B
. The colors listed above are the reflected light from the electric wires 2.2...
2 passes sequentially through the three primary color classification filters R1B and R1G and enters the line sensor camera 4. Accordingly, the camera 4 receives the light and sends a video signal, which is an analog signal, to the video processor 11 of the computer 10. However, the signal will be described in detail later.

In contrast to the embodiment shown in FIG. 1 above, in the case shown in FIG. The same optical color filter 5 as shown in FIG. For ..., the electrical signals corresponding to the spectral tristimulus values, which are the spectral sensitivities of the human eye, can be extracted, input into the computer 10, and analyzed as described below.
Reference numeral 13 in FIG. 2 is a condensing lens disposed on the hand Ail side of the line sensor camera 4.

Further, the optical color filter 6 shown in FIG.
They are arranged on the same radius and shifted by a rotation angle of 120 degrees, respectively, and are also provided with a rotation axis 8.

Furthermore, in the heterogeneous optical color filter 5 shown in FIG.
It is formed by connecting XB and G, and in this case, the same plate 6' is moved back and forth by a desired mechanism, for example, in front of the line sensor camera 4, thereby extracting signals for the three primary colors. That's what I do.

It is explained about an example of means for maintaining the aligned state according to the required pitch of the electric wires 2.2 and 2.
For example, it is preferable to use a rectangular parallelepiped alignment jig 14 as shown in FIGS. 5 and 6.

The jig 14 has a required plurality of penetration grooves 15, 15, .
... is provided, and for each connector 1 such as the LfC master, its connection side 1' is brought into contact with one side 14' of the jig 14, and at this time, the electric wires 2, 2, etc. are separated by color.
... into the above-mentioned penetration grooves 16, 15...,
Each electric wire 2.2... is pressed against the concave groove, and the electric wires are held at a predetermined pitch as shown in Fig. 6. It is preferable to hold down the colored electric wires 2, 2, etc. removed from the alignment jig 14 by appropriate removal.

Here, on the top of the alignment jig 14, there is a non-reflective surface part 16 made of black or the like, and the horizontally long jig 14.
It consists of reflective surface parts 17 and 17' formed on the left and right ends of the
Inside the recess 17.17' (1111 longitudinal edge 18.18'
However, from the adjacent Kansou-Ao 15.16..., 1st ff1i: 15.15's 1)fln self was set at a predetermined 1 pitch P (see Figure 5) to the 1st floor - to the right. I'm playing pat.

By using such an alignment jig 14, the video signal of 1.1 bits J of the line sensor camera 4 becomes as shown in FIG.

Since the resolution (CCU elements) of the licensor-camera 4 is 2048, the number CN of COD elements between the inner longitudinal edges 18 and 18' due to the reflective surface portions 17 and 17' is equal to the same number of COD elements CN on the right edge 18'. and C at each of the same end edge 18 on the left side.
This is the difference between CD elements CR and CLO. (CN=CR-CL
) and the color classification is 1 for electric wire 2.2...
The number of CCD elements CP in the pitch is 2.2...
・If the number of wires is N, then the value of each color in each concerned electric wire 2.2... is from CL -1-'< N・CP) to CL+(N
+1)・I1 corresponding to the number of each COD element between CP
It can be calculated by averaging 11.

The present invention can be carried out by using the apparatus and jig as described above, and as described above, if the master is applied to the apparatus as shown in FIG. 1 or FIG.
The light t1 irradiated on ...... is the same type 11N2.2.
The light reflected from... is the optical color filter 5
The transmitted light is transmitted through the segmentation filters 1t, B, and G in a predetermined order 9, and this transmitted light is received by the line sensor camera 4.

A video signal based on this transmitted light is then generated as an analog output of the camera 4 as described above with reference to FIG.
The video signal, which is an analog signal, is converted into a digital signal and becomes ready for processing by the computer/computer. . . . can be stored in the computer 11.

Next, for each π color, the test object with the electric wire connected to the connector is placed in the same <011 alignment jig 14 as the master, and then placed on the apparatus shown in FIGS. 1 and 2.

In this way, since the color arrangement of the electric wires can be measured for each color in the same way as before for the test object, it is compared whether or not the results match the stored color arrangement for the master mentioned above. This makes it possible to check whether there are any errors in the wire connection based on the color arrangement of the test object, that is, by color.

As described above, the present invention does not rely on human visual inspection and can determine correctness or incorrectness using a predetermined device. Therefore, it is possible to eliminate the errors caused by conventional methods, and therefore not only can provide highly reliable products, but also Since the work involves simply classifying the parts by color so that the electric wires are maintained at a predetermined pitch, the work efficiency is improved and the labor can be reduced to 1].
