Eight precautions for daily maintenance of manipulators

As a traditional manufacturing enterprise, using manipulators to change production methods is the only way to reduce the enterprise’s dependence on labor, reduce production costs, and achieve sustainable development. However, many companies lack the awareness and professional knowledge of daily maintenance after the introduction of manipulators, resulting in varying degrees of damage to the manipulators, resulting in increased operating costs.

For operators, the daily maintenance of the manipulator is very important. Here are some things to keep in mind:

1. Guide rails and bearings

Guides and bearings at all shafts should be kept clean and well lubricated. If the robot operates in a dusty environment, the guide rails need to be cleaned frequently. If you find any metal shards or powder, it could be a sign of poor lubrication.In order to ensure proper lubrication, it is critical to have a proper linear guide system, and most Robots haveautomationlubrication system and parts that need to be replaced regularly.

2. Robot cycle

　　

　

One of the keys to keeping a robot running well is simply watching and listening, which can reveal a lot about the overall operation of the robot. The manipulator works with specific movements, so listen for any abnormal sounds, such as whistling, clicking, etc., which indicate that the bearing is not rotating properly or that some other component is stuck. The linking part of the manipulator moves along the guide rail with the power cable and vacuum hose, and makes a normal clicking sound, but this sound is smooth and stable. Check any observable bearings to make sure they rotate smoothly. Just checking and listening for some signs of wear or need for adjustment can go a long way in keeping your robot operating at its best.

3. Drive system

If the manipulator is driven by a jig-drive gear, pay attention to whether there is any hesitation or shaking during operation. Any movement other than smooth, smooth action can indicate a damaged drive system or some foreign matter lodged inside. When the manipulator pushes downward, a quick way to check the motion or backlash between the assembly beam and the transmission gear is to push and drag the motion arm and feel the abnormal motion (the back and forth motion is different). However, this test method will be very imprecise due to the very high precision of normal manufacturer tolerances. If you suspect there may be a problem with the assembly beam and drive gear, a better approach is to use a long-range magnetic mount. After adjusting the backlash according to the manufacturer’s instructions, check the full travel of the shaft to ensure that there is no tightness between the assembly beam and the drive gear. If the backlash cannot be adjusted, the mounting bracket and drive gear may be worn and need to be replaced. If it is necessary to repair the mounting bracket and the drive gear, it is best to replace both components at the same time to ensure long-term performance. As for belt-driven shafts, pay close attention to belt wear and tear and damage to the belt itself. Carefully inspect the pulleys for signs of dust originating from the belt material. Make sure that the belt and drive pulleys and sheaves are perfectly aligned. Belts that deviate from the direction will wear out very quickly. As long as it is a belt driven system, the preload of the belt itself can be checked according to the manufacturer’s instructions. These specifications will tell you the appropriate amount of error in the specific position of the conveyor belt relative to the pulleys.

4. Pneumatic system

Including multi-axis servo drives, almost all manipulators will have pneumatic functions as long as they have wrist rotation and vacuum gripping actions. Pay close attention to the suction cup of the filter regulator unit, accumulation of water in it can indicate excessive humidity in the compressed air
