The detection method of the watch case BC surface adopts a computer vision technology based on the principle of binocular stereo vision. The first station camera and the second industrial camera capture images of the same scene from different angles to calculate the parallax information of each pixel in the image, and then obtain the three-dimensional information of the object in the actual space;

[0066] The action process of FC surface detection: the rotating drive member 511 drives the rotating disk 512 to rotate a certain angle, and the rotating disk 512 drives the case which is currently located at the second BC surface detection mechanism to rotate to the bottom of the FC surface detection mechanism. During this process, the rotating drive module 509 drives the gear disk 507 and the case to rotate to a first preset angle, and the two third industrial cameras 517 capture the image of the FC surface of the case from the first preset angle. The rotating drive module 509 drives the gear disk 507 and the case to rotate to a second preset angle again, and the two third industrial cameras 517 capture the image of the FC surface of the case from the second preset angle. The detection method of the FC surface of the case adopts a computer vision technology based on the principle of binocular stereo vision. The two third-station cameras capture images of the same scene from different angles to calculate the parallax information of each pixel in the image, and then obtain the three-dimensional information of the object in the actual space.

[0067] The scanning process: the rotating driving member 511 drives the rotating disk 512 to rotate a certain angle, and the rotating disk 512 drives the watch case located at the FC surface detection mechanism to rotate to the front side of the scanning mechanism, and the scanning gun 513 scans the QR code information on the watch case.

[0068] The defective product sorting process: the rotating drive part 511 drives the rotating disk 512 to rotate a certain angle, and the rotating disk 512 drives the watch case located at the code scanning station to rotate to the unloading position, and the unloading robot performs the sorting action. The unloading robot drives the clamping module to move above the unloading position, and the lifting cylinder 629 drives the clamping module to descend, and the clamping cylinder 631 drives the clamping arm 632 to clamp the watch case. If the watch case is not detected as defective, the unloading robot transfers the watch case to the material tray of the product unloading bin assembly. If the case is judged to be a defective product on the BC side or the FC side, the unloading robot clamps the defective case and transfers it to the tray of the third defective product unloading bin assembly. When the tray of the third defective product unloading bin assembly is full of defective products or the tray of the product unloading bin assembly is full of products, the unloading robot drives the tray clamping module 627 to move to the empty tray upper bin assembly. The tray clamping module 627 clamps the empty tray from the empty tray upper bin assembly and places it in the accommodating cavity 204 of the third defective product unloading bin assembly or the product unloading bin assembly.
