The invention discloses an in-service precision intelligent diagnosis and calibration
industrial robot system and a diagnosis and calibration method. The
system comprises a parameter acquisition module, a fault diagnosis engine module, a collaborative
calibration algorithm module, a
laser tracking calibration module, an execution calibration module and a result feedback module. According to the method, joint,
tail end, load and environment parameters of the
robot are collected through the parameter collection module and transmitted to the fault diagnosis engine module, and features are extracted and faults are classified through a specific technology; the collaborative
calibration algorithm module calculates a calibration compensation amount in combination with the fault parameters, and the
laser tracking calibration module tracks and measures the motion trail of the
robot in real time; the execution calibration module adjusts controller parameters to complete calibration, and the result feedback module compares the parameters and adjusts the acquisition frequency and type. According to the
system and the method, in-service real-time diagnosis and calibration of the
robot are realized, the fault diagnosis accuracy and the calibration precision stability are improved, the production interruption is reduced, the flexible production requirement is met, and the operation precision and the production efficiency of the robot are guaranteed.
