The detection mechanism inside the cabinet can sample images of the top and bottom of the processed stamping parts, facilitating computer comparison and detection of defective stamping parts. This device improves production speed and saves manpower by inspecting the appearance of the stamping parts. The tightness of the threaded rod and slide can be adjusted by turning the rotating block, and the height of the camera can be adjusted via the mounting block, facilitating the inspection of hardware stamping parts of different sizes.

[0039] A continuous conveying mechanism 4 for conveying the tailgate of a vehicle is installed on the base 1;

[0040] The base 1 is equipped with a defect marking component 5 for marking the detected defective parts;

[0041] In this invention, the tailgate is conveyed by the continuous conveying mechanism 4 to the area below the detection camera 2. The clamping assembly 34 clamps the tailgate, while the detection camera 2 detects the upper side of the tailgate. After detection, the driving assembly 31 drives the flipping assembly 33 to flip the tailgate. Then, the detection camera 2 detects the upper side of the flipped tailgate. When there are defects, the defect marking assembly 5 marks whether there are defects in the tailgate. Then, the tailgate after detection is output by the continuous conveying mechanism 4.

Then, a linear module 311 drives a rotating shaft 331 forward via a sliding block 312. At this time, a rack 333 drives a gear 332 to rotate. The gear 332, through the rotating shaft 331, drives the contour clamping rods 342 to rotate around the rotating shaft 331. When the rotating shaft 331 moves to the front end of the rack 333, the contour clamping rods 342 rotate 180 degrees. Then, the detection camera 2 detects the upper side of the tailgate. Then, the pneumatic gripper 341 drives the contour clamping rods 342 to release the clamp on the tailgate. The detection camera 2 continues to convey the tailgate, achieving continuous detection of the tailgate.

[0048] In this utility model, the belt conveyor 41 transports the tailgate of a vehicle to the conveyor wheel 43 on the left side of the base 1. The conveyor wheel 43 drives the tailgate to continue transporting it to the right. When the tailgate is transported to the middle position and is completely within the detection range of the detection probe, the pneumatic gripper 341 drives the contour clamping rod 342 to clamp and detect the tailgate. After the tailgate is clamped and flipped, the pneumatic gripper 341 drives the contour clamping rod 342 to release the clamp on the tailgate, and the conveyor wheel 43 continues to drive the tailgate to move to the right.

[0052] In this invention, when the detection camera 2 detects the tailgate and the tailgate is flipped, the driving end of the linear module 2 521 drives the lateral positioning plate 525 to avoid positional errors at the rightmost end of the linear module 2 521; when the detection camera 2 detects no defects in the tailgate, the spray head 513 sprays the corresponding color at a fixed position on the tailgate; when the detection camera 2 detects defects in the tailgate, the spray head 513 first sprays the corresponding color at a fixed position on the tailgate, and then...
