Inspection method of electric part, inspection apparatus of electric junction box and inspection apparatus of terminal fittings
First Claim
1. An inspection method of an electric part comprising the steps of:
- storing a plurality of images of a non-defective electric part in advance; and
judging whether or not an electric part to be inspected is non-defective on the basis of an image of the electric part to be inspected and a plurality of the images of a non-defective electric part.

Abstract
An inspection apparatus of an electric junction box is provided, by which improper mounting of electric parts can be detected. The inspection apparatus 1 has a CCD camera 5, an image-processing device 7 and a control device 8. The CCD camera picks up images of fuse 14 in the electric junction box 12 as a subject of the inspection. The image-processing device 7 stores an image consulting data 60. The image consulting data 60 includes a plurality of images of each fuse 14 having the same item symbol with regard to every item symbol, the fuses 14 being used in the electric junction box 12. The control device 8 stores normal data indicating the proper item symbol of the fuse 14 to be mounted on a corresponding mount 13. The image-processing device 7 extracts the image most analogous to the image picked up by the CCD camera 5 from the images in the image consulting data. The control device 8 judges the quality of the item symbol of the fuse 14 having the most analogous image on the basis of the normal data.
