The conveyor chain stops when the position of the moving pallet is detected by a photoelectric sensor. Conveyor chain 212 transports the empty moving pallet to the loading position 1 for reuse, carrying the outer ring of the wheel hub bearing for inspection. At one end of the inspection equipment located on the loading device 1, a transport mechanism 01 is installed between conveyor chains 211 and 212 to transport the moving pallet to the first end-face inspection station 3 for inspection. At the end of the inspection equipment away from the loading device 1, a transport mechanism 02 is installed between conveyor chains 211 and 212 to transport the moving pallet from conveyor chain 211 to conveyor chain 212 for recycling. The transport mechanism uses a motor-driven lead screw in the translation module to move and transfer the moving pallet via the upper moving pallet conveying assembly.

[0022] According to a preferred embodiment of the present invention, the wheel hub bearing outer ring appearance inspection equipment is equipped with a lifting and rotating mechanism at its first inner bevel inspection station 4, first side inspection station 5, second side inspection station 7, and second inner bevel inspection station 9. When the moving tray 22 carrying the wheel hub bearing outer ring to be inspected moves to the first inner bevel inspection station 4, the first side inspection station 5, the second side inspection station 7, and the second inner bevel inspection station 9, the lifting and rotating mechanism lifts the wheel hub bearing outer ring to be inspected and drives the wheel hub bearing outer ring to rotate for inspection. Figure 4 This is a schematic diagram of the lifting and rotating mechanism of the wheel hub bearing outer ring appearance inspection equipment of this utility model. (See attached diagram) Figure 4 The lifting and rotating mechanism includes a first servo motor 01, a first lead screw module 02, a second servo motor 03, a rotary gear set 04, and a hollow rotating drum 05. The first servo motor 01 drives the lead screw inside the first lead screw module 02, causing the rotating components on the first lead screw module 02 to move up and down. The second servo motor 03 is specifically a servo geared motor; a small spur gear on the servo geared motor 03 drives a large spur gear to rotate the hollow rotating drum 05. The rotating hollow rotating drum 05 causes the outer ring 001 of the wheel hub bearing above it to rotate continuously for detection. According to a preferred embodiment of this utility model, the lifting and rotating mechanism also includes a lead screw stepper motor 06. The output shaft of the lead screw stepper motor 06 passes through the hollow rotating drum 05 and connects to a flat panel light source 07.

When the conveyor chain 211 conveys the outer ring of the wheel hub bearing to the second end face inspection station 7, the cylinder 74 lifts the light source 75 to provide supplementary lighting to the inside of the outer ring of the wheel hub bearing, and the electric cylinder 71 drives the camera to move up and down to automatically adjust the camera focal length to obtain images of the end face and machined surface of the outer ring of the wheel hub bearing after it has been flipped for inspection.

[0024] According to the wheel hub bearing outer ring appearance inspection equipment of this utility model, the feeding device 1 transports the wheel hub bearing outer ring to be inspected to the designated position. The conveying mechanism 01 transports the moving pallet 22 carrying the wheel hub bearing outer ring to the first end face inspection station 3 for end face and turning surface inspection. Then, the wheel hub bearing outer ring is transported to the first inner bevel inspection station 4 via the conveyor chain 211. The hollow rotating cylinder 05 of the lifting and rotating mechanism lifts the wheel hub bearing outer ring and drives it to rotate continuously. At the same time, the flat plate light source 07 inside the hollow rotating cylinder 05 moves up and down to provide supplementary lighting to the inside of the wheel hub bearing outer ring. The camera at the inner bevel inspection station 4 acquires the inner bevel image of the wheel hub bearing outer ring for inspection. Subsequently, the conveyor chain 211 transports the wheel hub bearing outer ring to the first inner bevel inspection station 4. At the surface inspection station 5, the camera at the first side inspection station 5 takes pictures of the continuously rotating outer ring of the wheel hub bearing to obtain its side image for inspection. Then, the conveyor chain 211 transports the object to be inspected to the first flipping station 6, where the flipping mechanism of the first flipping station 6 flips the outer ring of the wheel hub bearing 180° for subsequent inspection. After flipping, the outer ring of the wheel hub bearing continues to be transported by the conveyor chain 211 to the second end face inspection station 7, the second side inspection station 8, and the second inner oblique opening inspection station 9 for inspection. After inspection of each surface, the flipping mechanism of the second flipping station 10 flips the outer ring of the wheel hub bearing back to its initial direction. Finally, based on the inspection results, the outer rings of the wheel hub bearings inspected are sorted at the unloading station 11.

[0025] Preferred embodiments of the present invention have been described above with reference to the accompanying drawings, and many features and advantages of these embodiments become apparent from this detailed description. Furthermore, since many modifications and alterations will readily occur to those skilled in the art, the embodiments of the present invention are not intended to be limited to the precise structures and operations illustrated and described, but rather to encompass all suitable modifications and equivalents.
