Embodiment Construction
[0029] Such as figure 1 As shown, the six-axis robot 10 is an industrial robot used for spot welding, arc welding, spraying, handling and other purposes. On the end effector 4 , the wrist 5 is located at the front end of the arm 6 . The robot 10 performs actions according to instructions from the robot diagnostic device 4, so as to position the wrist 5 and even the end effector 4 at any position; The robot diagnostic system 2 is a digital computer with a known hardware structure, and the known hardware structure includes CPU, ROM, RAM, non-volatile memory, display module and input and output interfaces.
[0030] Specifically, the multi-fault cause diagnosis system applied to industrial robots of the present invention includes a fault cause determination module 21 , a speed monitoring module 22 , a temperature monitoring module 24 , a data recording module 25 , and a display module 26 .
[0031] The shaft speed monitored by the speed monitoring module 22 is not limited to the...

The invention discloses a multi-fault cause diagnosis system and method applied to an industrial robot. The system comprises a speed monitoring module, a temperature monitoring module, a data recording module, a fault cause determining module and a display module, wherein the speed monitoring module is used for monitoring the shaft speed of each joint shaft of the six-axis robot according to a certain period; the temperature monitoring module is used for monitoring the temperature of a motor of each joint shaft of the six-axis robot according to a certain period; the data recording module is used for recording and storing the shaft speed data collected by the speed monitoring module and the temperature data collected by the temperature monitoring module; the fault cause determining moduleis used for carrying out feature extraction on a fault state signal and is used for performing preliminary analysis on the fault state signal after feature extraction and is used for performing jointtreatment on the preliminary analysis result and the shaft speed data and the temperature data recorded by the data recording module, the results of the the joint treatment are transmitted to the datarecording module, and data display is carried out through the display module. According to the multi-fault cause diagnosis system and method applied to the industrial robot, the fault cause determining module is set up, the fault cause of the six-axis robot is found in real time, and the display module is adopted for display, so that the fault cause is timely solved.
Description
technical field [0001] The invention relates to the technical field of industrial robots, in particular to a multi-fault cause diagnosis system and a diagnosis method applied to industrial robots. Background technique [0002] An industrial robot is a multi-joint manipulator or a multi-degree-of-freedom machine device for the industrial field. It can automatically perform work and realize various functions by its own power and control capabilities. During the operation of the robot, sometimes it is affected by the surrounding If the failure occurs due to the interference of people or objects, or the failure of the robot is caused by the robot itself, the following technology is mainly proposed to protect the people who work around the robot when a failure occurs. [0003] The purpose of the prior art is mainly to protect people working around the robot during an emergency stop. However, when the robot is stopped in an emergency for safety, the life of the robot is shortened...
