Industrial Robot Maintenance Cycle: By Time or Operating Hours? Methods for Developing a Plan

Even two robots of the same model installed in the same year can experience vastly different actual wear rates due to differences in cycle time, load, dust, temperature, and range of motion.

1. Key Inspection Points
2. Record daily operating time, number of motion cycles, load, and proportion of high-speed motion.
3. Differentiate the different cycles for control cabinet filter pads, batteries, fans, lubrication, and accuracy checks.
4. In environments with high temperature, dust, oil mist, or welding spatter, inspection intervals should be shortened.
5. Adjust the plan by combining alarm history, temperature rise, vibration, backlash, and historical replacement records.
6. Processing Steps
7. Establish a four-level task system: daily inspection, monthly inspection, quarterly inspection, and annual maintenance.
8. Bind critical items to operating hours or cycle counts, rather than relying solely on date-based reminders.
9. Record measured values, component status, materials used, and follow-up observation items during each maintenance session.
10. Regularly compare data from similar equipment to identify robots with abnormal wear rates.
11. Common Misconceptions
12. Using exactly the same maintenance cycle for all robots.
13. Only performing cleaning and lubrication, without checking brakes, backlash, and electrical connections.
14. Maintenance records only stating 'completed,' lacking actual measurements and component status.
15. Summary

The robot maintenance cycle should consider calendar time, operating hours, motion cycles, load, environment, and historical failures simultaneously, and cannot rely solely on a fixed annual cycle.
