In this process, the quality of the Nd-Fe-B magnet on the conveying belt 1 can be detected in real time by the plurality of quality detectors 15. The quality detector 15 is centrally symmetrically provided with two groups, which can realize double detection, thereby improving the accuracy of detection. At the same time, when the quality detector 15 detects that the produced Nd-Fe-B magnet is abnormal, it will transmit a signal to the peripheral controller. The peripheral controller controls the alarm 10 to issue an alarm and controls the conveying belt 1 to stop working. At this time, the worker can hold the detector 12 to detect the Nd-Fe-B magnet located below the alarm 10 which issues an alarm one by one. After the detection is completed, the Nd-Fe-B magnet with quality problems is picked out, and the control panel 2 is operated to start the conveying belt 1 again to convey the Nd-Fe-B magnet to be detected. Through the convenient pre-screening of the Nd-Fe-B magnet, the detection efficiency of the Nd-Fe-B magnet can be effectively improved, the detection efficiency is high, the detection effect is good, and the problem that the existing Nd-Fe-B magnet needs to be detected after production, and the Nd-Fe-B magnet produced is detected by manual holding of the detector 12.

The quality detectors 15 are symmetrically arranged along the center and can realize double detection, so as to improve the accuracy of detection. When the quality detector 15 detects that the produced neodymium iron boron magnets are abnormal, a signal is transmitted to the peripheral controller, the peripheral controller controls the alarm 10 to issue an alarm, and controls the conveyor belt 1 to stop working. At this time, the worker can hold the detector 12 to detect the neodymium iron boron magnets one by one under the alarm 10 which issues an alarm. After the detection is completed, the neodymium iron boron magnets with quality problems are picked out, and the control panel 2 is operated to start the conveyor belt 1 again to convey the neodymium iron boron magnets to be detected.
