Abstract

PROBLEM TO BE SOLVED: To easily detect whether or not data stored in a memory in a harness checker are abnormal, by comparing the data stored in the memory in the harness checker with inspection data stored in a memory card after a wire harness is completely inspected. SOLUTION: Data stored in a memory in a harness checker are naturally coincident with inspection data stored in a memory card. Therefore, whether or not data stored in the memory of the harness checker are abnormal can be easily detected by comparing the data with the inspection data stored in the memory card after a wire harness is finished to be inspected. If the data stored in the memory in the harness checker include abnormalities, data are again stored in the memory in the harness checker and then the wire harness is re-inspected. Whether the product is good or not can thus be surely detected.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a wire harness inspection method for inspecting the electrical continuity of a wire harness.

[0002]

2. Description of the Related Art A wire harness is formed by bundling a plurality of electric wires, and the plurality of electric wires are connected at predetermined positions so as to form a predetermined electric circuit. After the wire harness is assembled into a predetermined shape, it is electrically inspected to check whether the electric circuit has an error.

Conventionally, when conducting an electrical continuity inspection of a wire harness, a memory card storing inspection data of the wire harness to be inspected is prepared,
The data stored in the memory card is stored in the memory inside the harness checker, and the electrical continuity test of the wire harness is performed based on the data stored in the memory inside the harness checker.

[0004]

However, in the conventional inspection method, the data stored in the memory in the harness checker may be rewritten for some reason. In such a case, the product is defective. Nevertheless, there was a problem that it was judged as a good product, or it was judged as a defective product even though the product was a good product.

[0005]

SUMMARY OF THE INVENTION The present invention has been made in view of the above problems. Even if the data stored in the memory inside the harness checker is rewritten for some reason, it is detected. It provides a method of inspecting the wire harness that enables you to judge the quality of the product.
That method, the inspection data stored in the memory card is stored in the memory inside the harness checker, in the inspection method of the wire harness based on the data stored in the memory inside the harness checker, in the inspection method of the wire harness, After the inspection of the wire harness is completed, the data stored in the memory inside the harness checker is compared with the inspection data stored in the memory card.

[0006]

[Operation] It is premised that the data stored in the memory inside the harness checker and the inspection data stored in the memory card originally match. For this reason, after the inspection of the wire harness is completed, by collating the data stored in the memory inside the harness checker with the inspection data stored in the memory card,
It is possible to easily determine whether or not there is an abnormality in the data stored in the memory inside the harness checker. If the data stored in the memory inside the harness checker is abnormal, the data can be stored again in the memory inside the harness checker, and then the inspection can be performed again, so that the quality of the product can be surely determined.

DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will be described below in detail with reference to the drawings. FIG. 1 is a block diagram showing steps of a method for inspecting a wire harness according to the present invention.

First, a memory card in which inspection data of a wire harness to be inspected is stored is prepared. Next, this memory card is set in the harness checker, and then the power 1 of the harness checker is turned on. By turning on the harness checker,
The data stored in the memory card is transferred 2 to the memory in the harness checker and stored there.
Then, the start switch 3 of the harness checker is inserted and the inspection 4 of the electric circuit of the wire harness is performed. This inspection is performed based on the data stored in the memory inside the harness checker.

If the inspection is passed 5, then the data stored in the memory inside the harness checker is compared 6 with the inspection data stored in the memory card. This makes it possible to easily determine whether or not the data stored in the memory inside the harness checker is abnormal. If the result of comparison is a mismatch 7, an error display 8 is displayed. On the other hand, if the result of collation is a match 9, a pass signal 10 is output, and then the inspection of the electric circuit is started.

By performing the above method for each electric circuit, it is possible to eliminate an erroneous inspection due to an abnormality in the data stored in the memory in the harness checker.

In the above embodiment, after the inspection of the wire harness has passed the inspection, the data stored in the memory inside the harness checker is compared with the inspection data stored in the memory card. However, even if the inspection of the wire harness is unsuccessful, the data stored in the memory inside the harness checker is compared with the inspection data stored in the memory card after that. By doing so, it is possible to easily determine whether or not the reason why the inspection fails is due to an error in the data stored in the memory in the harness checker. In addition, the data stored in the memory inside the harness checker can be checked against the inspection data stored in the memory card not only after the inspection of the wire harness has been completed, but the data stored in the memory card can be checked in the harness checker. It may be done after transferring to memory. By doing so, it is possible to easily confirm whether or not there is an error in the data transfer.

[0012]

As described above, according to the wire harness inspection method of the present invention, the data stored in the memory inside the harness checker and the inspection data stored in the memory card after the inspection of the wire harness are completed. It is possible to easily determine whether or not there is an abnormality in the data stored in the memory inside the harness checker in order to check the above. Therefore, it is possible to reliably prevent an inspection error based on the abnormality of the data stored in the memory inside the harness checker.
