Hey there! As a supplier of the MHS Series 4 finger pneumatic gripper, I've seen my fair share of common problems that users might run into. In this blog, I'll walk you through how to troubleshoot these issues, so you can keep your gripper running smoothly.
1. Gripper Not Opening or Closing Properly
One of the most common problems is when the gripper fails to open or close as it should. There could be a few reasons for this.
Air Supply Issues
First off, check the air supply. A low or inconsistent air pressure can prevent the gripper from functioning correctly. Make sure the air pressure is within the recommended range specified in the product manual. You can use a pressure gauge to measure the air pressure at the inlet of the gripper. If the pressure is too low, check the air compressor and the air lines for any leaks. Look for any visible signs of air escaping, like hissing sounds or bubbles if you apply soapy water to the connections.
Valve Problems
The control valve might also be the culprit. If the valve is not working properly, it won't send the right signals to the gripper to open or close. Inspect the valve for any signs of damage or blockage. Sometimes, debris can get into the valve and prevent it from operating smoothly. You can try cleaning the valve or replacing it if necessary.
Mechanical Blockage
There could be a mechanical blockage inside the gripper itself. Check for any foreign objects that might be stuck between the fingers or in the moving parts of the gripper. Remove any debris carefully using a small tool like tweezers or a brush. Make sure not to damage any of the internal components while doing this.
2. Uneven Gripping Force
Another issue that users often face is uneven gripping force. This means that one or more fingers of the gripper might not be applying the same amount of force as the others.
Finger Alignment
Check the alignment of the fingers. If the fingers are not properly aligned, they won't grip the object evenly. You can use a straight edge or a gauge to check if the fingers are parallel to each other. If they are misaligned, you might need to adjust the mounting of the fingers or the gripper itself. Make sure all the mounting bolts are tightened securely.
Wear and Tear
Over time, the fingers of the gripper can wear out, which can lead to uneven gripping force. Inspect the fingers for any signs of wear, like scratches or deformation. If the fingers are worn out, you can replace them with new ones. It's a good idea to keep some spare fingers on hand for this kind of situation.
Air Flow Distribution
The air flow distribution to each finger might also be uneven. Check the air lines that supply air to each finger. Make sure there are no kinks or blockages in the lines. You can also try adjusting the flow control valves if your gripper is equipped with them to balance the air flow to each finger.
3. Excessive Noise During Operation
If your gripper is making a lot of noise during operation, it could be a sign of a problem.
Lubrication Issues
Lack of proper lubrication can cause excessive noise. The moving parts of the gripper need to be lubricated regularly to reduce friction and noise. Check the product manual to see what type of lubricant is recommended for your gripper. Apply the lubricant to the appropriate parts, like the joints and the sliding surfaces of the fingers.
Loose Components
Loose components can also create noise. Check all the bolts and screws that hold the gripper together. Make sure they are tightened properly. If any of the components are loose, they can vibrate and make noise during operation. Tighten them up to eliminate the noise.
Worn Bearings
If the gripper has bearings, they might be worn out. Worn bearings can cause a lot of noise and can also affect the performance of the gripper. Inspect the bearings for any signs of damage, like excessive play or rough surfaces. Replace the bearings if necessary.
4. Leakage
Leakage is another common problem that can occur with pneumatic grippers.
Seal Damage
The seals in the gripper are responsible for preventing air from leaking out. Check the seals for any signs of damage, like cracks or tears. If the seals are damaged, they need to be replaced. You can usually find replacement seals from the manufacturer or a supplier.
Connection Leaks
Check all the connections between the air lines and the gripper. Make sure they are tightened properly. Sometimes, the connections can loosen over time, causing air to leak. You can use a wrench to tighten the connections, but be careful not to over-tighten them, as this can damage the fittings.
