Daily (Performed by operators): Clean the robot body surfaces, sensor probes, and electrical cabinet ventilation vents; check pneumatic system pressure (0.4–0.6 MPa) and inspect grippers/suction cups for wear; perform a test run to ensure joints operate smoothly without binding or abnormal noise.
Weekly (Performed by maintenance personnel): Inspect the cable/hose package for casing hardening or exposed wire cores; tighten any loose screws on the end-effector flange and base mounting bolts; replenish specialized grease at all moving joints.
Monthly (Performed by equipment engineers): Conduct a comprehensive inspection of cables and hoses for wear; calibrate robot positioning accuracy; replenish gearbox lubricant; test motor insulation performance; replace pneumatic system filter elements.
Annually (Performed by the manufacturer or senior engineers): Completely replace gearbox lubricant and all-machine grease; replace aged pneumatic seals; back up all control system programs; perform zero-point calibration and load testing for the entire unit.
