[0027] As Figure 1As shown, the embodiment of the present application provides an automatic feeding vibration mechanism based on industrial vision, comprising: an external support plate 1, a vibrating disc 2, a turnover mechanism 3, a steering mechanism 4, a discharge guide rail 5, a camera A 7, a camera B 8, wherein the vibrating disc 2 is installed in the external support plate 1, the turnover mechanism 3, the steering mechanism 4, the camera A 7 and the camera B 8 are all installed on the side wall of the external support plate 1, so as to avoid damage to the turnover mechanism 3, the steering mechanism 4, the camera A 7 and the camera B 8 caused by the vibration of the vibrating disc 2; the discharge guide rail 5 is fixedly connected with the outer side wall of the vibrating disc 2 through a support rod 6; the turnover mechanism 3 is used for overturning the material on a vertical plane, and the steering mechanism 4 is used for rotating the material on a horizontal plane; from the advancing direction of the material, the camera A 7, the turnover mechanism 3 and the camera B 8 are arranged in sequence, and the steering mechanism 4 is located on one side of the camera B 8.

[0028] As shown in the figure, Figure 2 When the vibrating disc 2 is running, the material passes through the camera A 7, the turnover mechanism 3, the camera B 8 and the steering mechanism 4 in sequence, and finally enters the discharge guide rail 5; when the material passes below the camera A 7, the camera A 7 takes a photo of the material, judges the posture of the material based on the vision detection system, and generates an operation scheme of the turnover mechanism 3 according to the posture of the material. Similarly, the camera B 8 generates an operation scheme of the steering mechanism 4 based on the photo taken by the camera B 8.

[0029] In this way, the posture of the material in the conveying track can be adjusted in real time according to the detection results of the camera A 7 and the camera B 8.

[0032] As Figure 3 shown in one embodiment of the present application, the turnover mechanism 3 further comprises a baffle 36, which is driven by a linear transmission mechanism, such as a cylinder, and can move along the radial direction of the groove wheel 32. Since the material has a tendency to move towards the direction 5 when it is in the groove wheel 32, the baffle 36 can be moved to block the containing groove 35 when the groove wheel 32 is turned over, so as to avoid the material moving along the radial direction of the groove wheel 32 during the turnover process.

[0035] As Figure 6As shown, in one embodiment of the present application, the suction cup module 44 comprises a movable tube 441, a suction cup 442, a spacer 443, an interface 444, and a nut 445.
