Description

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a fitting confirmation method and a type confirmation method for a fitting having two fitting bodies fitted to each other.

"Prior art" In devices such as automobiles and home electric appliances, a fitting having two fitting bodies fitted to each other, such as a connector having a plug and a socket fitted to each other, is used.
In the manufacturing process of these devices, it is necessary to confirm that the two fitting bodies of the fitting are fitted. Conventionally, this fitting is visually confirmed by a person.

When fittings are used in various parts of the equipment, confirm that the two fittings of each fitting are fitted together, and at the same time, It is necessary to confirm whether or not this is the case. Conventionally, however, a person also visually confirms the type of this fitting.

[Problems to be Solved by the Invention] However, when a person visually confirms the fitting and the type as in the related art, it takes time and effort for the confirmation, and may cause an erroneous recognition.

In view of the above, the present invention has been made so that the fitting can be easily confirmed without error and the type of the fitted object can be easily confirmed without error.

[Means for Solving the Problems] In the fitting that realizes the fitting confirmation method of the present invention, the two fittings are placed on the same plane when these two fittings are fitted. Consisting of a convex part and a concave part between them,
When the two fitting bodies are fitted, the fitting confirmation unevenness is formed continuously at a constant pitch.

In the fitting confirmation method according to the present invention, the fitting confirmation unevenness of the fitting is scanned by a reader, and the reader scans the projection of the fitting confirmation irregularity from the reader. A read signal having a different level is obtained between a period in which the concave portion is scanned and a time period of a specific period corresponding to one pitch or a convex portion or a concave portion of the read signal including a boundary between two fitting bodies of the fitting confirmation concave and convex portions. Is compared with one pitch of the fitting confirmation unevenness before and after the specific period or the time width of the period corresponding to the convex portion or the concave portion, and is determined by whether or not the ratio between the two is within a predetermined range. It is determined whether or not the fitting bodies are fitted.

In the fitting for realizing the type checking method of the present invention, the above-mentioned fitting confirmation unevenness is formed on a plane of the two fitting bodies which becomes the same surface when these two fitting bodies are fitted. Along with this, the type confirmation unevenness in a mode corresponding to the type of the fitting is formed.

Here, the “type” of the fitting is not only a difference in the type and structure of the fitting, but also a difference in a place where the fitting is used when the fitting is used in each place of one device. This also includes different types of fittings due to differences in the devices in which the fittings are used.

In the fitting confirmation method and the type confirmation method of the present invention, the fitting confirmation unevenness of the fitting is scanned by the first reader, and the type confirmation unevenness is simultaneously scanned by the second reader. From the first reader, the first reader obtains a first read signal having a different level during a period in which the first scanner scans the convex portion of the fitting confirmation unevenness and a period in which the first scanner scans the concave portion. , A second reader obtains a second read signal having different levels during a period in which the second reader scans the convex portion of the type confirmation unevenness and a period in which the concave portion scans the concave portion. It is determined whether or not the two fitting bodies are fitted by the above method, and the type of the fitted object is determined from the second read signal.

[Operation] In the present invention, it is possible to easily confirm the fitting, and it is determined whether or not the two fitting bodies are fitted to each other by the play of the fitting of the two fitting bodies and the reading of the reader. Accurate determination is made irrespective of the variation or fluctuation of the scanning speed, and the fitting can be confirmed without error.

In addition, since the type confirmation unevenness is formed side by side with the fitting confirmation unevenness, and both are simultaneously scanned by two readers,
The type of the fitting can be easily confirmed without error.
