XYZ Linear Translation Stages are Loaded To Client from UK

XYZ linear translation stages are precision mechanical devices used to move an object or a sample in a controlled and precise manner along three orthogonal axes: X, Y, and Z. These stages are commonly used in various applications such as microscopy, semiconductor manufacturing, metrology, and optical testing.

XYZ linear translation stages typically consist of a platform or carriage that can move along each axis, driven by precision screws, linear motors, or piezoelectric actuators. They are often equipped with position feedback sensors for precise positioning.

Eight precautions for daily maintenance of robotic arms/XYZ linear translation stages: 

1: Guide rails and bearings
All guide rails and bearings at the axis should be kept clean and have good lubrication performance. If the XYZ linear translation stages operate in a dusty environment, it is necessary to clean the guide rails regularly. If you find any metal fragments or powder, it may indicate poor lubrication. It is crucial to have an appropriate linear guidance system to ensure proper lubrication, as most robotic arms have automated lubrication systems and components that require regular replacement.
2: Mechanical arm cycle
One of the key points to maintaining good operation of XYZ linear translation stages is simple observation and listening, which can reveal a lot of information about the overall operation of the robotic arm. The robotic arm works through specific actions, so it listens to any abnormal sounds, such as whistling, clicking, etc., which indicate that the bearing cannot rotate properly or that some other component is stuck. The connecting part of the robotic arm moves along the guide rail equipped with power cables and vacuum hoses, producing a normal clicking sound, but this sound is smooth and stable. Check any observable bearings to ensure they rotate smoothly. Just checking and listening for signs of wear or adjustment can greatly help maintain the optimal operating state of the robotic arm.
3: Drive system
If the robotic arm is driven by an assembly frame transmission gear, pay attention to whether there is any hesitation or shaking during operation. All movements except smooth and smooth movements can indicate damage to the drive system or the presence of foreign objects inside. The method to quickly check the movement or backlash between the assembly beam and the transmission gear during the downward movement of the robotic arm is to push and drag the moving arm, feeling abnormal movement (different back and forth movements). However, due to the high precision of normal manufacturer tolerances, this test method will be very imprecise. If you suspect that there may be problems with the assembly beam and transmission gear, a better approach is to use a magnetic gauge holder with a long range. After adjusting the backlash according to the manufacturer’s manual, check the entire travel of the shaft to ensure that there is no too tight space between the assembly beam and the transmission gear. If the backlash cannot be adjusted, the assembly frame and transmission gears may wear out and need to be replaced. If it is necessary to repair the assembly frame and transmission gear, it is best to replace both components simultaneously to ensure long-term performance. As for the shaft driven by the conveyor belt, pay close attention to the debris falling from the worn conveyor belt and its own damage. Carefully inspect the pulley and pay attention to any signs of dust originating from the conveyor belt material. Ensure that the conveyor belt, drive pulleys, and groove pulleys are completely arranged in a row. A conveyor belt that deviates in direction will wear out very quickly. As long as it is a conveyor belt driven system, the preload of the conveyor belt itself can be checked according to the manufacturer’s instructions. These specifications will tell you the appropriate amount of error at the specific position of the conveyor belt relative to the pulley.

4: Pneumatic system
Including multi axis servo drive, as long as there is wrist rotation and vacuum gripping action, almost all robotic arms will have pneumatic function. Pay close attention to the suction cups of the pressure regulating valve unit, as water accumulation indicates excessive humidity in the compressed air source passing through the system. The presence of a small amount of water vapor can be transmitted to pneumatic valves and actuators, causing oxidation and internal contamination, ultimately leading to sticking of the pressure regulating valve or intermittent sticking or failure of the actuator. If the suction cup is equipped with an automatic dehumidification system, contamination or discoloration on the suction cup also indicates an increase in moisture before removal. If water accumulates in the suction cup, even for a short period of time, it can still enter the system, causing the above problems. If you notice any tangible damage to the pneumatic hose, there may be a leak in the system.
If the pneumatic circuit is filled with air at normal operating pressure and there is a leak somewhere in the circuit, you should be more likely to notice a noticeable hissing sound, which can help you determine the location of the leak.
5: Check the molding equipment
The standard configuration of XYZ linear translation stages is usually installed on the template of the forming equipment. When the equipment is running rapidly, vibrations from the forming equipment may be transmitted to the robotic arm and can cause damage. By simply observing the operation of the molding equipment, ensuring that the mold movement is adjusted to a reasonable state, reducing the number of shaking or vibration, the lifespan of the robotic arm can be extended. In high-speed operation, the vibration frequency may be very high, and it is best to install the robotic arm on a support structure independent of the forming equipment.
6: Pay attention to wiring wear and tear
When inspecting the surface of a mechanical watch, if black particles or powder are found, it indicates signs of wear in the wiring of the mechanical arm circuit. However, even if you cannot detect these wear signals, carefully examine all power, transformer, or encoder cables, both inside and outside of the wiring path, because during the production cycle, the wiring of the continuous friction manipulator or the wiring connected to the cable guide will eventually wear and fail. Ensure the safety of wiring ties and the proper installation of cables.
7: Check lubrication
The robotic arm uses spring loaded lubrication rods, which only need to be replaced once a year unless there is evidence of insufficient lubrication of the guide rail. Configure an automated lubrication system that can continuously lubricate along the movement of XYZ linear translation stages. However, if there are some surfaces on which the robotic arm cannot move normally, manual lubrication should be applied to these areas, or regular programmed lubrication actions should be implemented through automated systems for lubrication. If you find rust, corrosion, or wear on any moving surface, or if it is just too dry, it indicates that they are not lubricated enough. Always refer to the manual of the robotic arm for proper lubrication of metal components. The traditional gear system of the assembly beam is automatically lubricated through a lubricating oil storage unit, but it needs to be replaced annually.
