The Six-axis industrial robot is a critical tool for improving the efficiency of manufacturing processes in industrial fields such as precision production and metal machinery. In addition to paying attention to their operating performance, operators cannot ignore their maintenance during daily use. This is a critical process. Combining many years of experience in manufacturing and maintenance, we will provide you with maintenance tips for six-axis industrial robots in this article, which operators can implement to extend their service life.

Regular lubrication of Six-Axis Industrial Robot to ensure smooth movement

Regular lubrication is essential for the optimal performance of six-axis industrial robots, guaranteeing smooth movement and enhancing overall operational efficiency. This maintenance practice involves the application of specific lubricants to the robot’s moving components, including joints, gears, and bearings. By reducing friction, preventing wear, and minimizing heat generation, lubrication contributes to the machine’s longevity and reliable functionality. Common lubricants include oils, greases, and dry lubricants, each chosen based on its suitability for specific applications. The benefits of regular lubrication include minimizing friction-related wear, reducing the risk of component failure, extending the robot’s service life, dissipating heat, and preserving smooth and precise movement, ultimately maintaining the machine’s precision and accuracy.

Perform calibration and accuracy checks on the six-axis industrial robot!

Calibration is a systematic process integral to fine-tuning the control systems, feedback devices, and sensors of six-axis industrial robots to meet established standards. These standards may be industry specifications or project-specific requirements. During calibration, parameters like joint angles, tool position, and end-effector orientation are adjusted to eliminate deviations from desired values.

Accuracy checks follow the calibration process, consistently evaluating a machine’s ability to achieve accurate and repeatable motion. These assessments involve measuring machine components’ position and orientation and comparing them to expected values. High-precision instruments such as laser trackers or coordinate measuring machines are often employed. Calibration and accuracy checks are tailored to the machine’s design, complexity, and application, considering factors like clearance, thermal expansion, and mechanical wear. Advanced techniques, including laser interferometry and kinematic modeling, are applied to highly complex six-axis industrial robots.

Perform inspections of cable and wiring systems

Regular inspections of cable and wiring systems are crucial for maintaining the reliability and safety of six-axis industrial robots. These inspections involve a comprehensive examination of electrical components, cables, and wire harnesses to identify potential issues that could impact the robot’s performance or pose safety risks.

Cables and wiring systems are vital in transmitting power, signals, and control commands between different robot parts. Inspectors conduct visual inspections to check for signs of wear, cuts, or exposed wires, with particular attention to areas experiencing repetitive motion. Additionally, operators perform electrical testing, including continuity testing, insulation resistance measurements, and signal integrity checks. These tests ensure safe electrical connections and reliable signal transmission, contributing to the overall reliability and safety of the six-axis industrial robot.

Perform software updates and system diagnostics

Software updates for six-axis industrial robots encompass enhancements to the robot operating system, control algorithms, programming interfaces, and application-specific software. These updates improve accuracy, speed, and efficiency while ensuring compatibility with new peripherals, sensors, or programming languages. Before initiating updates, operators perform a system backup to safeguard existing configurations and programming. This precaution allows for a seamless restoration to the previous state in case unexpected issues arise during the update process.

Operators install the new software version on the robot’s control system, potentially requiring rebooting, recalibrating, or reconfiguring specific parameters. Thorough testing and verification follow the update to confirm the robot’s proper operation and the intactness of safety features. System diagnostics play a vital role in maintaining a six-axis industrial robot. Diagnostics utilize built-in self-tests, remote monitoring systems, and external diagnostic equipment to evaluate hardware components, sensors, actuators, and communication interfaces. Operators leverage these diagnostics to minimize downtime and prevent unforeseen failures.

Perform emergency stop system testing

Activation of the emergency stop system is a critical safety feature in six-axis industrial robots, rapidly bringing the robot to a controlled stop to prevent accidents, protect operators, and avoid equipment or workpiece damage.

To conduct an emergency stop system test, operators follow predefined procedures or safety guidelines provided by the manufacturer. This may involve activating an emergency stop button switch or triggering the emergency stop function through a designated control interface. Activation mechanisms vary based on the robot’s design and implemented safety protocols.

Operators observe the robot’s response during the test, ensuring an immediate complete stop with all movements halted and power cut to relevant components. Visual and audible indicators confirm the successful activation of the emergency stop system. Post-test, operators verify that the system has effectively disconnected power and stopped all dangerous movements. A thorough check of the robot’s condition allows for any necessary maintenance or adjustments, enhancing the reliability of the emergency stop system.

Maintain regular maintenance

Proactive and regular maintenance ensures six-axis industrial robots’ longevity, accuracy, and reliability. By adhering to these maintenance practices, operators can streamline the production process, minimize downtime, and ultimately optimize the overall efficiency of the manufacturing process.
