This system is suitable to be installed on the AOI visual inspection machine to cooperate with the vision sorting machine; to realize the sorting of the wrong magnetics magnetic pole. The system can automatically detect, automatically sorts, and automatically alarm.
The principle of BKN magnetic imaging detection technology is to distinguish the magnetic pole direction by testing the relationship between the magnetic field intensity H of the magnetics and the induced magnetic induction intensity B.
Working process: Using a magnet with the correct magnetic pole passes through the probe to obtain a complete signal. OK and NG is distinguished by comparing the similarity between defective and qualified products. Detect whether there is a difference in the magnetic pole of the magnetics, to ensure that the detection result is 100% accurate.
1. It can distinguish any magnetics with the wrong magnetic pole;
2. No magnetization will be generated after testing;
3. The setting is fast, accurate and convenient, can be completed in 3 minutes;
4. Good test repeatability;
5. Simple operation, touch screen operation mode, adopts man-machine dialogue interface;
6. The display is clearly, and the test results NG and OK are displayed in real-time;
7. It is suitable for the needs of large-scale testing and guarantees qualified product quality;
8. Non-destructive testing, no special requirements on the surface of the workpiece;
9. The detection speed is 60～480 pieces/minute (the posture of the magnetic material on the glass plate must be consistent, and the two materials must be separated);
