The conveying module 100 is used to convey the workpieces 500, and the workpieces 500 are evenly distributed on the conveying module. The image acquisition module 200 is used to acquire surface image information of the workpiece 500, and the image acquisition module 200 is installed on the conveying module 100, and the image acquisition module 200 is electrically connected to the comparison module 600. The comparison module 600 is used to compare the collected image information of the workpiece 500 with the standard image information, and the comparison module 600 is electrically connected to the control module 400. The control module 400 is used to control the operation of the rejecting module 300 .

[0017] The rejection module 300 is used to reject the workpiece 500 with surface defects. The workpiece 500 is a bottle-shaped structure, and has an annular protrusion at the bottle mouth of the workpiece 500 .

[0018] When the system is implemented, the conveying module 100 conveys the workpiece 500, and then the image acquisition module 200 can acquire images of the workpiece 500. The acquired image information can be marked as T1. After receiving the T1 information, the comparison module 600 can compare it with the image information of the intact workpiece 500 T0 therein. After the comparison is completed, when there is no defect on the surface of the workpiece 500, the conveying module 100 can convey the workpiece normally, and when there is a defect on the surface of T1, the comparison module 600 can transmit a signal to the control module 400, so that the rejection module 300 starts working to reject the damaged workpiece.

[0019] The rejection module includes a shell 1, in which a fixed frame 2 capable of moving up and down is arranged, the fixed frame 2 is a door-type structure with an opening facing downward, and two symmetrically distributed movable frames 4 are arranged on the fixed frame 2, the movable frames 4 can approach / move away from each other, and when the movable frames 4 approach each other, the movable frames 4 can combine with the bottle mouth of the workpiece 500, and a slidable blanking plate 13 is also arranged on the shell 1.

[0020] When the fixed frame 2 moves downward, the two movable frames 4 approach each other until the two movable frames 4 are combined with the bottle mouth of the workpiece 500, and then the fixed frame 2 moves upward to remove the workpiece 500 from the conveying module 100. When the fixed frame 2 moves upward to a predetermined height, the unloading plate 13 can move to the bottom of the workpiece 500, and at this time the workpiece 500 can fall from the movable frame 4.

[0021] A threaded rod 6 is fixedly connected to the movable frame 4, and the threaded rod 6 passes through the fixed frame 2. A rotating mechanism is rotatably provided in the fixed frame 2.

During this process, one of the rotating wheels 8 can cooperate with the first rack 9, so that the rotating block 16 rotates. When the rotating block 16 rotates, the threaded rod 6 can move to one side so that the two movable frames 4 are close to each other and the workpiece 500 is clamped; then the fixed frame 2 moves upward. At this time, the two rotating wheels 8 and the first rack 9 do not contact each other. When it rises to a predetermined height, the other rotating wheel 8 cooperates with the other first rack 9, so that the rotating wheel 8 can also move to the other side during the rotation process.
