The invention discloses a vision inspection device for appearance defects of rollers, and relates to the technical field of vision inspection devices. The device comprises a first conveying belt, a second conveying belt, a first image device, a first image processing system and a first inferior-quality product removing device and further comprises a rotating disc, a rotating disc driving device, roller sucking devices, a second image capturing device and a second image processing system. The first conveying belt conveys rollers to be inspected, the second conveying belt conveys qualified rollers, and the first image capturing device, the first image processing system and the first inferior-quality product removing device inspect the appearance defects of the upper sides of the rollers and remove unqualified inferior-quality products; and the rotating disc, the rotating disc driving device, the roller sucking devices, the second image capturing device and the second image processing system are used for inspecting the appearance defects of the lower sides of the rollers and remove the unqualified inferior-quality products. Vision inspection can be comprehensively carried out on the rollers in a no-dead-corner manner, and meanwhile, the unqualified inferior-quality products are removed; and automation and intelligence of the whole process are achieved, and precision and efficiency of roller inferior-quality product inspection can be improved.
