Problems solved by technology

[0004] The detection results using traditional methods are easily affected by factors such as visual fatigue, proficiency level, and emotional fluctuations of quality inspectors. It is difficult to meet the current production speed and requirements in terms of accuracy, stability, and detection speed, resulting in misjudgments, missed judgments, Misjudgment occurs. In addition, human contact also has a certain probability of damaging the magnetic ring.

Example Embodiment

[0053] The following describes the implementation of the present invention in detail with reference to the drawings and embodiments.

[0054] Such as figure 1 with figure 2 As shown, the ring-shaped vibrating table 1 uses a conveyor belt to send the magnetic ring to the ring-shaped rotating device 4; the magnetic ring position fixing device 2 is located above the ring-shaped rotating device 4, and there are shields and fixed objects along the radial direction of the ring-shaped rotating device 4. The constraining magnetic ring makes a constant circular motion with a fixed radius on the annular rotating device 4 along with the annular rotating device 4. The magnetic ring is placed on the annular rotating device. The annular rotating device is transparent to ensure that the bottom surface of the magnetic ring can be used by the camera 5. Photographed. At the same time, fix the annular rotating device 4 to prevent it from shaking;

Abstract

The invention discloses a multi-vision magnetic ring defect detection method and a multi-vision magnetic ring defect detection system and aims to realize multi-camera simultaneous online detection and intercommunication. Eleven cameras are respectively connected with six mainframes to complete defect detection of different stations, the six mainframes send detection results to a master controller through serial ports, and the master controller judges six channels of signals; when the six channels of signals are all GOOD, the master controller controls an air pump to blow magnetic rings into one of holes through a detection outlet, and otherwise, the magnetic rings are blown into the other hole. According to a core concept of a detection algorithm, two of the cameras are used for taking images of upper and lower surfaces of the magnetic rings, one of the camera is used for taking height images of the magnetic rings, the other eight cameras in surrounding arrangement are used for taking inner and outer ring images of the magnetic rings and distributed uniformly to guarantee 360-degree shooting of inner and outer ring areas of the magnetic rings, and different defect detection programs run at different stations. By adoption of the method, the whole system reaches 240-260 magnetic rings per minute in detection speed, 0% in false collection rate and 3% in false detection rate, a detection radius can reach 29mm, and industrial production requirements can be met.
