For the maintenance of the Estun ER120-2400-PL four-axis robot, the following general recommendations and steps can be followed:

Routine inspection and maintenance

：

Lubrication of mechanical structures

• 

: Regularly check the lubrication of each joint area, and add or replace the lubricating oil according to the schedule recommended by the manufacturer's manual.

Inspection of transmission components

• 

: Check whether the transmission parts on each shaft, such as gears, reducers, timing belts, lead screws, etc., are working properly and whether there are signs of wear or looseness.

Connectors are fastened

• 

: Ensure that all mechanical connectors (e.g. bolts, pins) are tightened without loosening to prevent connection failure due to vibration.

Cable harnesses

• 

Check whether the robot power cable, signal cable, gas pipe, water pipe and other wiring harnesses are damaged and aging to ensure the safety of electrical and pneumatic systems.

Servo system maintenance

：

Servo motor

• 

: Monitor the working temperature, sound and vibration of the motor, regularly clean the heat sink of the motor, and keep the servo drive clean.

encoder

• 

: Confirm that the feedback signal of the encoder is accurate, so as to avoid affecting the accuracy due to contamination or damage.

Control system maintenance

：

Controller status

• 

: Check the operating log of the control system for error messages or warnings, and perform necessary software updates and calibrations.

Battery maintenance

• 

: If the controller contains a battery backup unit, replace the battery at a specified interval to protect the system settings from loss.

End effectors and other accessories

：

• 

If the robot is equipped with welding tools, grippers or other special end-effectors, its functionality and safety should be specifically checked and maintained, including wire feeding mechanisms, welding torch cooling systems, etc.

Planned maintenance

：

• 

Develop and execute a regular overhaul program based on the equipment manufacturer's recommendations, which may include replacement of wear parts, deep cleaning, accuracy correction, and more.

Recording & Tracking

：

• 

Record the content of each maintenance and repair, and establish a complete equipment maintenance file for long-term tracking and management of the robot status.

Please be sure to refer to the specific maintenance manual provided by Shandong Bensen Intelligence, because the maintenance requirements for different models of robots may be different.
