1、 Why do industrial robots require regular maintenance?
In the era of Industry 4.0, the proportion of industrial robots used in an increasing number of industries is constantly increasing. However, due to their long-term operation under relatively harsh conditions, equipment failures often occur. As mechanical equipment, no matter how constant temperature and humidity the robot operates, it will inevitably wear out. If daily maintenance is not carried out, many precision structures inside the robot will experience irreversible wear and tear, and the service life of the machine will be greatly shortened. If necessary maintenance is lacking for a long time, it will not only shorten the service life of industrial robots, but also affect production safety and product quality. Therefore, strictly following correct and professional maintenance methods can not only effectively extend the lifespan of the machine, but also reduce its service life and ensure the safety of equipment and operators.
2、 How should industrial robots be maintained?
The daily maintenance of industrial robots plays an irreplaceable role in extending their service life. So how to carry out efficient and professional maintenance?
The maintenance inspection of robots mainly includes daily inspection, monthly inspection, quarterly inspection, annual maintenance, regular maintenance (50000 hours, 10000 hours, 15000 hours), and major repairs, covering nearly 10 main projects.
In daily inspections, the main focus is on conducting detailed inspections of the robot body and electrical cabinet to ensure smooth operation of the robot.
In regular inspections, replacing grease is the most important, and the most important thing is to check the gears and reducer.
1. Gear
Specific operation steps:
When supplementing or replacing grease, please supplement according to the prescribed amount.
2. Please use a manual oil gun to replenish or replace the grease.
3. If you need to use an air pump oil gun, please use the ZM-45 air pump oil gun (produced by Zhengmao Company, with a pressure ratio of 50:1). Please use a regulator to adjust the air supply pressure to be less than 0.26MPa (2.5kgf/cm2) during use.
During the oil replenishment process, do not directly connect the grease discharge pipe to the outlet. Due to the filling pressure, if the oil cannot be discharged smoothly, the internal pressure will increase, causing seal damage or oil backflow, resulting in oil leakage.
Before refueling, the latest Material Safety Data Sheet (MSDS) for grease should be followed to implement precautions.
When supplementing or replacing grease, please prepare a container and a cloth in advance to handle the grease flowing out from the injection and discharge ports.
7. The oil used belongs to the Industrial Waste Treatment and Cleaning Act (commonly known as the Waste Treatment and Cleaning Act). Therefore, please handle it correctly according to local regulations
Note: When loading and unloading plugs, use a hex wrench of the following size or a torque wrench attached to the hex rod.
2. Reducer
Specific operation steps:
1. Move the robot to zero the arm and turn off the power.
2. Unscrew the plug on the oil outlet.
3. Unscrew the plug on the injection port and then screw in the oil nozzle.
4. Add new oil from the injection port until the old oil is completely discharged from the drain port. (Judging old oil and new oil based on color)
5. Unscrew the oil nozzle on the oil injection port, wipe off the grease around the oil injection port with a cloth, wrap the plug around 3 and a half turns with sealing tape, and screw it into the oil injection port. (R1/4- Tightening torque: 6.9N · m)
Before installing the oil outlet plug, rotate the J1 axis of the oil outlet plug for a few minutes to allow excess oil to be discharged from the oil outlet.
7. Use a cloth to wipe off the grease around the oil outlet, wrap the plug around 3 and a half turns with sealing tape, and then screw it into the oil outlet. (R1/4- Tightening torque: 6.9N.m)
