摘要： An article visual inspection apparatus capable of detecting that the surface conditions of an article are so inferior as to render the article unusable as a product and rejecting the same as a defective article by inspecting the article for external defects, occurring on the surface of the article, such as streaks, dice marks and rough surfaces of an aluminum extruded shape. The visual inspection apparatus comprises an imaging device (1) for imaging the surface of the article, and an image processing device (3) for capturing the picked up image. The image processing device (3) has a plurality of image processing units that compare a captured image with a set judging reference value to evaluate the result, whereby the quality of surface conditions is evaluated based on external defects such as streaks, dice marks and rough surfaces of an aluminum extruded shape, and evaluations by the respective image processing units are weighted by a weighting unit to thereby comprehensively judge whether to accept or reject the article.

摘要： A method and a device for identifying an upper surface and a lower surface of a component having asymmetric upper and lower outer shapes are provided. In particular, a method and a device for identifying orientation of an item that hardly allows visual identification of the upper and lower surface. A disk-like, cylindrical, or annular component having asymmetric upper and lower outer shapes is placed on a reference surface having a reference block, an outer peripheral part of the component on the reference surface is brought into contact with the reference block, and identification of the upper and lower surface of the component is achieved in an inline system based on a gap created between the outer peripheral part of the component and the reference block, using a light source lighting device and a detection camera arranged across the reference block.

摘要： A method and a device for identifying an upper surface and a lower surface of a component having asymmetric upper and lower outer shapes are provided. The components include, for example, disk-like, cylindrical, or annular components, more specifically engine parts having an orientation such as piston rings. In particular, a method and a device for identifying orientation of an item that hardly allows visual identification of the upper and lower surface. A disk-like, cylindrical, or annular component having asymmetric upper and lower outer shapes is placed on a reference surface having a reference block, an outer peripheral part of the component on the reference surface is brought into contact with the reference block, and identification of the upper and lower surface of the component is achieved in an inline system based on a gap created between the outer peripheral part of the component and the reference block, using a light source lighting device and a detection camera arranged across the reference block.
