When an industrial robot is incorporated into a manufacturing line, the goal is to minimize unintentional downtime and the likelihood of component failure or deterioration.
FREMONT, CA: Industrial robots maintenance has evolved significantly in recent years, with the introduction of preventive and predictive maintenance concepts.

Preventive Maintenance: It assists in preventing equipment failure by replacing failing components systematically and identifying and addressing problems before the collapse.
This procedure conducts a routine inspection of the electrical and mechanical systems, system evaluations, lubrication of the shaft and ball joints, oil change in the gearbox, measurements and corrections, arts being phased out, and backup of equipment degradation records.
Predictive Maintenance: A condition monitoring solution indicates the system's various pressure, temperature, and humidity conditions. The procedure would entail the amount of data about asset and process trends available in the current time and the past. It enables operators to detect and diagnose potential problems. It provides operators with analytics and alerts as needed. However, implementing this type of predictive maintenance system across an entire facility's assets is not profitable. Having a firm grasp on these concepts might assist us in saving time and money on upkeep.
Industrial robots, when properly maintained, can last for many years, if not decades, before needing to be replaced. By following a routine preventative maintenance schedule, engineers can significantly increase the robot's life. The many prominent robots brands propose scheduling preventative maintenance every 12 months, while others schedule it according to their working hours. After 10,000 hours, it is regarded as convenient to do so. It is critical to consult the documentation for the robot to determine when this is appropriate. Planning this maintenance is the most prudent course of action because, with it scheduled, the interruption of output will be minor compared to the time lost in the event of an unexpected shutdown. Each robot manufacturer has its maintenance manual, which they should consult when scheduling preventative maintenance. For instance, FANUC suggests performing specific preventive maintenance checks daily, after 600 hours of operation and after 5,000 hours of operation.
Engineers must schedule and perform preventative maintenance according to the manufacturer's recommended schedules. Regular inspections help prevent minor issues from growing into larger ones and enable the maintenance crew to operate around peak production schedules.
