Title:
溶接部検査装置
Document Type and Number:
Japanese Patent JP6606202
Kind Code:
B2
Abstract:
The present invention relates to a welded section examining device. In order to examine whether welding is good or bad of a welded section joining tip portions of electrical conductors projecting from slots of a stator core, a welded section examining device includes a camera, a discriminating unit, a wavelength-converting sheet, and a masking member. The camera images the welded section. The discriminating unit performs discrimination of whether welding is good or bad based on an outline of the welded section recognized from an image of the welded section imaged by the camera. The wavelength-converting sheet irradiates the welded section with a light, from a rear surface side of an imaging target surface. The masking member is interposed between the wavelength-converting sheet and the rear surface of the welded section, such that the outline of the welded section is imaged in the camera in an emphasized state.
