Device for inspecting external appearance of electronic parts

Abstract

Abstract PURPOSE:To prevent the generation of undetection of defective parts and the dispersion of decision due to visual inspection by providing the titled device with an arithmetic means for calculating the height of electric parts from a substrate on the basis of information obtained from an image recognizing device. CONSTITUTION:A recognizing device provided with a top camera 53 and a lighting lamp 54 which are arranged so that an optical axis is vertical to the upper face of a substrate 4 and side camera 55, 55a-55c and lighting lamps 56, 55a-55c are arranged so that optical axis is oblique to the upper face of the substrate 4 is prepared. The titled device is also provided with the arithmetic means for calculating the height of the electronic parts 52 from the substrate 4 on the basis of information obtained from the recognizing device and and the recognizing device can be relatively rotated. Consequently, the defect, positional shift, floating, and solder state of the electronic parts 53 mounted on the substrate can be inspected.
