[0002] In an intelligent fault diagnosis device for industrial robots, an intelligent detector is a key device for detecting faults in robots. It can collect various data during the operation of the robot through various sensors, such as current, voltage, temperature, vibration, etc., and then use built-in intelligent algorithms and analysis models to process and analyze these data, so as to quickly and accurately determine whether the robot has faults and the specific location and type of the faults. The structure and control system of the robot are relatively complex, and it is difficult for manual detection to comprehensively and accurately detect potential faults. However, the intelligent detector can collect and analyze a large amount of data in real time and automatically, improving the efficiency and accuracy of fault detection. The intelligent detector can monitor the robot in real time, detect early fault signs in time, give early warnings, and avoid serious production accidents and economic losses caused by the further development of faults. The intelligent detector can also record and store the detection data, providing important reference for subsequent fault analysis, equipment maintenance, and optimization and upgrading, which helps to continuously improve the reliability and operation efficiency of the robot.
