The present invention relates to an appearance inspection device for a ceramic molded article, which photographs an inspection portion of a ceramic molded article formed by sintering, and reads the image of the photographed inspection portion to inspect whether cracking occurs at the inspection portion. The appearance inspection device for a ceramic molded article according to the present invention comprises: a fixing jig which is provided with a placement space for a ceramic molded article provided with a hollow inspection section; a flood lamp which irradiates light in a direction from an outer surface to an inner surface of the hollow inspection section of the ceramic molded article placed on the fixing jig, to project a crack generated in the hollow inspection section to the inner surface; a camera module which photographs the inner surface of the hollow inspection section of the ceramic molded article to acquire an inspection image; and a reading unit which reads the inspection image acquired through the camera module, detects whether a crack image acquired by projecting the crack generated in the hollow inspection section in the inspection image is formed, and determines whether a crack occurs in the hollow inspection section. The crack formed in the hollow inspection section is projected to the inner surface of the hollow inspection section by light diverged from the flood lamp and projected to the hollow inspection section. |
