Description
Technical Field
The invention relates to the technical field of detection of silicon nitride bearing balls, in particular to a nondestructive detection device for defects of a silicon nitride bearing ball with multi-level defect classification.
Background
The silicon nitride bearing ball has the properties of low density, high hardness, no magnetism and the like, and is widely applied to the fields of electronics, chemical industry, aviation, aerospace, automobiles, national defense and the like. The nondestructive testing device for the surface defects of the silicon nitride bearing ball is used for positioning, detecting and evaluating the defects of the tested object on the premise of not damaging the performance and the integrity of the silicon nitride bearing ball by a non-contact testing method.
The existing nondestructive detection methods for the surface defects of the silicon nitride bearing ball include a ray detection method, a machine vision detection method and the like. The ray detection method generates different scattering and absorption to rays according to the differences of the density, the thickness and the like of the silicon nitride bearing ball, and further judges indexes such as the size, the surface characteristics and the like of the silicon nitride bearing ball. The radiation detection method is to collect the transmitted radiation intensity distribution image obtained after the radiation irradiates the silicon nitride bearing ball through the detector, and analyze the defect of the silicon nitride bearing ball through the image. The method has long detection time, high cost and high environmental requirement, and is not suitable for industrial continuous detection. The machine vision detection method is simple in detection process, an industrial camera is used for collecting pictures of the surface of the silicon nitride bearing ball, and relevant image analysis software is used for identifying defects such as cracks, scratches and the like on the surface of the silicon nitride bearing ball. Compared with the ray detection method, the machine vision detection method has high detection efficiency, good continuity and higher flexibility, and can realize industrialized continuous detection. Therefore, the machine vision detection method has great advantages over the radiation detection method, but the prior art detection device adopting the machine vision detection method still has the following technical problems:
1. The collision among the silicon nitride bearing balls in the detection process is a main cause of secondary damage to the surfaces of the silicon nitride bearing balls. The existing nondestructive testing device for the surface defects of the silicon nitride bearing balls mainly uses a vibration disc for feeding, the hopper is vibrated in the vertical direction through pulse electromagnetic under the hopper of the vibration disc, and the hopper is driven by an inclined spring piece to perform torsional pendulum vibration around the vertical axis of the hopper. The parts in the hopper rise along the spiral track due to the vibrations. In the whole feeding process, the silicon nitride bearing balls collide with each other, and secondary damage to the silicon nitride bearing balls is easily caused.
2. The rotation of the silicon nitride bearing ball is realized through the friction force between the silicon nitride bearing ball and the detection device, for example, the silicon nitride bearing ball is driven to rotate through a plurality of cylindrical rollers, so that the image acquisition of the whole outer surface of the silicon nitride bearing ball is conveniently carried out through a CCD camera, and the acquired picture is compared with a standard picture to screen out the silicon nitride bearing ball containing defects. However, the rotation mode of the silicon nitride bearing ball based on friction force is also easy to cause secondary damage of the silicon nitride bearing ball, and the camera cannot be guaranteed to acquire images of the whole spherical surface.
3. The existing nondestructive testing equipment for the surface defects of the silicon nitride bearing balls has only two kinds of sorting discharge of the detected silicon nitride bearing balls, namely the defective silicon nitride bearing balls and the nondefective silicon nitride bearing balls. In practice, however, defective silicon nitride bearing balls can still be classified again to detect the reusable silicon nitride bearing balls based on the corresponding defect classification algorithm. If the secondary-usable silicon nitride bearing balls can be discharged in a classified manner, the production cost can be reduced, the resource waste can be reduced, and the detection device has a wider market prospect.

the silicon nitride bearing ball 36 to be detected is placed in the upper bin 4, the feeding cylinder 8 controls the feeding sucker 5 to suck the top of the silicon nitride bearing ball 36 from the upper bin 4 and extract the silicon nitride bearing ball, the silicon nitride bearing ball 36 is sent to the initial section of the horizontal feeding mechanism through the linear guide rail 7, and the silicon nitride bearing ball 36 is placed in a groove on the conveyor belt 35.
During the feeding process of the conveyor belt 35, the top detection mechanism detects the top of the silicon nitride bearing ball 36, namely, the line scanning camera I10 performs one-time image acquisition on the top surface of the silicon nitride bearing ball 36. After the end of one image acquisition, the silicon nitride bearing ball 36 reaches the end section of the horizontal feeding mechanism along with the conveyor belt 35.

In the process that the silicon nitride bearing ball 36 rotates along with the rotation of the cylindrical external gear I39, the lower detection mechanism detects the lower part of the silicon nitride bearing ball 36, namely, the line scanning camera II 24 performs secondary image acquisition on the surface of the silicon nitride bearing ball 36 except the top. After the secondary image acquisition is finished, the detection is finished.

The inspected silicon nitride bearing balls 36 reach the sorting turntable I48 from the discharge port of the discharging bin 45.
