IRB6700 robot maintenance information

Robot maintenance is not only crucial to the performance and life of the robot, but also plays an important role in improving production efficiency, ensuring operational safety, and reducing maintenance costs. Regular maintenance is a critical step in ensuring your robot continues to operate efficiently.

When repairing and inspecting the robot control cabinet, make sure the main power supply is turned off.

Part1: Precautions when replacing lubricating oil

1. The oil temperature may be higher than 90 degrees, replace it after cooling Wear gloves to prevent allergic reactions
2. Open the oil drain hole carefully and slowly to prevent oil from splashing.

Part 2: Gearbox oil level check and replacement

1-axis gearbox oil level inspection and replacement

1. Handling gearbox oil involves some safety risks. Before proceeding, please read the robot safety information
2. Turn off all power sources connected to the robot before entering the robot working area. For the hydraulic source and air pressure source, do not cut off the air source for the Foundry Prime version.
3. Open the oil filling plug and check
4. The required oil level is 5mm below the edge of the oil plug hole
5. Refuel as needed
6. Cover the oil plug hole. Note: Tightening torque: 24NM

1-axis gearbox oil replacement (oil drain)

1. Handling gearbox oil involves some safety risks. Before proceeding, please read the robot safety information
2. Turn off all power sources connected to the robot before entering the robot working area. For the hydraulic source and air pressure source, do not cut off the air source for the Foundry Prime version.
3. Use an oil collector to collect waste oil
4. Open the filling plug to drain oil more quickly
5. Open the oil drain plug and drain the waste oil into the oil collector. Note: The oil drain time is related to the oil temperature.
6. Cover the oil plug hole

1-axis gearbox oil replacement (refueling)

1. Handling gearbox oil involves some safety risks. Before proceeding, please read the robot safety information
2. Turn off all power sources connected to the robot before entering the robot working area. For the hydraulic source and air pressure source, do not cut off the air source for the Foundry Prime version.
3. Open the refueling hole and refuel
4. Add an appropriate amount of lubricating oil. The amount of oil depends on previous consumption.
5. Do not mix Kyodo Yushi TMO 150 lubricant with other models
6. Cover the oil plug hole. Note: Tightening torque: 24Nm
