Abstract: A defect inspection device for metal ring end faces of a Continuously Variable Transmission (CVT) V-belt which enables automated inspection of end face defects in the metal rings along with acquiring improved efficiency, superb precision and reproducibility. When end face defects in the metal ring are inspected by an inspection section, this task is accomplished by an angle modification portion which performs an angle modification operation continuously in a predetermined range (?1˜?5) relative to an inspectable surface for at least a first light guiding path and a second light guiding path included in the defect inspection section. Because this automated modification operation corresponds to processing by manual visual inspection and applies a common practice detection method used in labor-intensive visual inspections by changing the viewing angle to detect defects, such as a gloss mark, the object of the present invention can be achieved.

Abstract: A metal surface inspection device for metal rings of a Continuously Variable Transmission (CVT) V-belt which does not perform excessive detection of mackerel skins as a detrimental manufacturing flaw. This task is achieved by providing an “integral value calculation portion” for calculating an integral value of a difference value and a “difference value correction portion” for correcting the difference value in a decreasing direction as the integral value increases. When mackerel skins contained on an inspectable surface are detected the output (integral value of the difference value) of the integral value calculation portion increases. Accordingly, the difference value is corrected in a decreasing direction which enables the operation to control the signal of the mackerel skin portions and threshold values are not exceeded which prevents excessive detection.

Abstract: A metal surface inspection device which does not perform excessive detection of a harmless flaw, for example, a gloss mark. This task is achieved by providing a first discrimination portion which compares a difference value and a predetermined threshold value for discriminating the presence of a defect on an inspectable surface. This discriminated result is “provisional” and a final discrimination result is obtained by the operation of a second discrimination portion. Here, among the discriminated results of the first discrimination portion, the discrimination duration time corresponding to a harmful flaw is shorter and to the contrary the discrimination duration time corresponding to a harmless flaw is longer. Consequently, the difference between a harmful flaw and a harmless flaw are distinguishable by adjusting a discrimination reference value in the second discrimination portion.
