Robot Breakdown Prediction System in Automobile Factories

System Overview

This system prevents long stoppages of production lines by the motor failure of manufacturing robots. When it detects a predictor of robot breakdown based on the actual current waveform of a robot motor compared with the normal one, it alerts to prevent production line stoppage through preventive maintenance or other precautions.

Systems Diagram

The motor currents in each axis of industrial robots are measured to monitor the load status of the motors. Current waveforms are obtained for each robot cycle. If the current value is out of threshold level, the system issues an alarm to notify the operator and prevent equipment stoppage.

This system is created using the industrial computers and analog data acquisition boards both from CONTEC.
