[0002] The existing disc burst bead screening system is mainly realized by centrifugal force to screen burst bead, and the design screening speed is 1.4 million per hour, and after practical operation, it is found that the actual screening speed is about 800,000 per hour. After research, it is found that the burst bead screening speed of the above-mentioned existing disc burst bead screening system is closely related to the rotating speed of the rotating disc. Since the weight of the burst bead is light, when the rotating speed is too high, the burst bead will move uncontrollably due to the centrifugal force, so that the defective burst bead cannot be screened out. In order to make the burst bead screening qualified, the rotating speed has to be reduced, which results in the reduction of the screening speed and the inability to further improve the production capacity, which cannot meet the actual production needs.

[0021] The frame is equipped with a motor to drive the conveyor belt 2 and rollers to support the conveyor belt. The conveyor belt 2 has a receiving cavity 21 for accommodating the popping beads. The bottom of the receiving cavity 21 is a through hole. The receiving cavity 21 is preferably a rectangular perforation. The side length of the rectangular perforation is adapted to the diameter of the popping beads. Generally, after the popping beads are put into the receiving cavity, the lower half of the popping beads protrudes from the lower edge of the receiving cavity. The inscribed circle of the popping beads and the receiving cavity is located above the lower edge of the receiving cavity. Support plates 22 are provided below the conveyor belt 2 on both sides of the rubbing belt 3. Of course, the receiving cavity can also be other shapes, as long as the size is roughly adapted to the popping beads. When the conveyor belt moves forward, the receiving cavity pushes the popping beads forward. The frame 1 is also equipped with a cleaning roller brush 23 that rotates and contacts the conveyor belt for cleaning the conveyor belt 2. It also includes a hopper 74 set at the beginning of the conveyor belt 2. The burst beads to be tested are placed in the hopper. The discharge end of the hopper has a flat nozzle structure that can just accommodate a row of burst beads. When the hopper is opened, the burst beads fall in rows into the receiving cavity on the conveyor belt under the action of gravity.

A cleaning roller brush 32 is also mounted on the mounting frame 33 for cleaning the agitating belt 3 and rotatably contacts it. A light source 9 is also included, located below the agitating belt 3 and directed towards the intersection of the conveyor belt 2 and the agitating belt 3.
[0023] The camera 5 is positioned at the intersection of the conveyor belt 2 and the rubbing belt 3. During detection, the light source shines upwards, passing sequentially through the support plate, the rubbing belt, and the popping beads before being captured by the camera.
[0024] A straw is provided above the conveyor belt 2 in front of the camera 5, and an air blowing tube is provided below the conveyor belt corresponding to the straw. The number of air blowing tubes corresponds one-to-one with the number of the receiving cavities in a row on the conveyor belt 2. The straws include defective straws 61 and repairable straws 62, and the air blowing tubes include air blowing tube one 81 and air blowing tube two 82, which correspond to the defective straw 61 and the repairable straw 62, respectively.
[0025] The inner wall of the accommodating cavity on the conveying belt pushes the blasting bead to move forward, the rubbing belt pushes the bottom of the blasting bead to rotate laterally, the camera continuously takes pictures in the travel of the intersection of the conveying belt and the rubbing belt, then transmits the pictures to the image processing device for picture synthesis processing to obtain the complete three-dimensional scanning structure of the blasting bead, the real-time taken pictures and the synthesized pictures can clearly display the all-around picture information of the blasting bead, so as to judge whether the blasting bead has defects and whether the defects can be repaired, and then the valve of the suction pipe and the blowing pipe is opened or closed through the PLC control, the corresponding blasting bead is blown up at the specified position, is sent to the unqualified product box 71 or the repairable product box 72 through the suction pipe, and the qualified product falls into the qualified product box 73 along with the conveying belt.
