[0030] When the bearing to be inspected is conveyed by the conveyor belt 1 to the bottom of the outer diameter surface inspection mechanism 3, the first hydraulic cylinder 32 is activated to push the rotating motor 33 and the rotating frame 34 to move downward, so that the first inspection camera 35 corresponds to the outer diameter surface of the bearing. The rotating motor 33 is started, driving the rotating frame 34 and the first inspection camera 35 to rotate. The first inspection camera 35 takes a full-scale picture of the outer diameter surface of the bearing, and the first fill light 36 provides sufficient light for shooting to ensure the clarity of the captured image. By analyzing the captured image, the appearance quality of the outer diameter surface of the bearing, such as scratches, cracks and other defects, can be detected.

[0031] See also Figure 3 The upper end surface detection mechanism 4 includes a second support frame 41, which is fixedly mounted on the frame of the conveyor belt 1.

Due to the reverse thread action on the threaded rod 752, the two moving blocks 754 will move relative to each other, so that the two arc-shaped clamping blocks 755 approach and clamp the bearing. Then, the servo flip motor 72 is started, and the bearing is flipped 180° through the rotating shaft 73, the connecting block 74 and the clamping assembly 75, so that the lower end surface of the bearing faces upward, so as to perform the lower end surface inspection.
