The utility model discloses an
electric vehicle hub motor appearance detection device based on a
computer vision system, which comprises a conveying mechanism, a carrier, a
camera module, a
light source module and a computer
system, the carrier is connected to the conveying mechanism and can move along the surface of the conveying mechanism, the carrier is used for placing and fixing a hub motor to be detected, and the
camera module is connected to the
camera module. A rack is fixedly connected above the conveying mechanism, the camera module, the
light source module and the computer
system are all connected to the rack, the camera module is used for shooting and identifying a hub motor, the
light source module is used for illuminating the hub motor, and the computer system is connected with and controls the camera module and the light source module. The camera module can automatically detect and judge the problems of omission, deformation and the like of
laser etching characters of products by using an OCR technology, and judges whether the problems of omission of oil seal installation, reverse installation of oil seal, missed installation of screws, valve hole
dislocation after
assembly of a hub and a side cover and the like exist or not by using a
visual comparison technology, so that omission and misjudgment caused by manual inspection are completely eradicated.
