Q&A

Frequently Asked Questions
COMMON PROBLEM
1. When using the gripper to pick up, there is a requirement for rotational concentricity, so the gripper fingers are close to each other on both sides. Is it always stopped in the middle position each time?
Answer: Yes, there is a symmetrical error of <0.1mm, with a repeat accuracy of ±0.02mm.
2. Do claw products include the front fixture part?
Answer: No, users need to design the fixture themselves based on the actual items to be gripped. In addition, Huiling also provides a few fixture libraries. Please contact the sales personnel to obtain them.
3. Where is the drive controller for the claw, and does it need to be purchased separately?
Answer: The driver is built-in and does not need to be purchased separately.
4. Can the Z-EFG gripper move with a single finger?
Answer: No, grippers that can move with a single finger are currently under development. For specific details, please contact the sales representative.
5. What are the gripping forces of Z-EFG-8S and Z-EFG-20, and how are they adjusted?
Answer: The gripping force of Z-EFG-8S is between 8-20N, and it can be manually adjusted via the potentiometer on the side of the gripper. The gripping force of Z-EFG-12 is 30N and is not adjustable. The default gripping force of Z-EFG-20 is 80N. If customers require other gripping forces, they can specify this at the time of purchase. The value is set to the customer’s custom specifications before leaving the factory.
6. How are the strokes of Z-EFG-8S and Z-EFG-20 adjusted?
Answer: The strokes of Z-EFG-8S and Z-EFG-12 are not adjustable. The Z-EFG-20 is a pulse-type gripper, with 200 pulses corresponding to a 20mm stroke and 1 pulse corresponding to 0.1mm stroke.
7. For the Z-EFG-20 pulse-type gripper, 200 pulses correspond to a 20mm stroke. What will happen if 300 pulses are sent?
Answer: For the standard 20-pulse-type gripper, the extra pulses will not be executed and will not cause any impact.
8. Z-EFG-20 pulse-type gripper, if I send 200 pulses, but the gripper grabs the object at 100 pulses, will it stop after grabbing? Are the remaining pulses still useful?
Answer: The gripper will maintain a fixed clamping force at the current position after gripping the object. After the external force removes the object, the fingers will continue to move.
9. How to determine if the electric gripper has grabbed something?
Answer: The IO-type series of Z-EFG-8S, Z-EFG-12, and Z-EFG-20 can only determine if the gripper has stopped. For the Z-EFG-20 pulse-type gripper, the feedback pulse count reflects the gripper’s current position, so the user can determine if the object has been gripped based on the number of feedback pulses.
10. Is the electric gripper Z-EFG series waterproof?
Answer: Not waterproof, special requirements can be consulted with the sales staff.
11. Can objects larger than 20mm be gripped using the Z-EFG-8S or Z-EFG-20 grippers?
Answer: Yes, here 8S and 20 refer to the effective stroke of the gripper, not the size of the object being gripped. If the maximum to minimum size difference of the object being gripped is within 8mm, it can be gripped using Z-EFG-8S. Similarly, if the maximum to minimum size difference of the object being gripped is within 20mm, it can be gripped using Z-EFG-20.
12. If working continuously, will the motor of the electric gripper overheat?
Answer: After professional testing, the Z-EFG-8S can work continuously at an ambient temperature of 30 degrees, and the surface temperature of the gripper will not exceed 50 degrees.
13. Does the Z-EFG-100 gripper support IO or pulse control?
Answer: Currently, the Z-EFG-100 only supports control via 485 communication. Users can manually set parameters such as movement speed, position, and gripping force.
