Five advantages of industrial robots with servo electric grippers

In the electric gripper or servo gripper, the motor controls the movement of the jaws through the electrical input of the robot controller. These robot arm end tools are increasingly appearing in the industrial market. Here are five advantages of using electric grippers compared with other types of robot grippers.

1. Control the position of fingers

By using a coded motor and an appropriate control scheme, the position of the jaws can be determined using an electric clamp. On the contrary, for traditional grippers, it is usually necessary to maintain the full stroke all the time. When using the electric gripper, you can flexibly use only the smallest necessary clearance to approach the part, and then make the smallest stroke to pick it up. Partial opening and closing help to select a wider range of part sizes without affecting the production cycle.

2. Test grip strength

Using the encoder, it is possible to determine whether the gripper has picked up the part. Some electric grippers transmit this information back to the robot controller. In many applications, the handle must be detected in order to prevent errors. Doing this at the gripper level avoids putting other sensors in the loop, simplifies integration and reduces overall costs.

3. Control grip and speed

Since the motor current is proportional to the applied torque, the grip paper force applied by the paper teeth can be controlled. The same is true of the closing speed. For example, this may be helpful when dealing with fragile parts.

4. No gas pipe: save power and maintenance costs

Many companies are switching from pneumatic to electric to reduce operating costs. An important aspect of this transformation is the reduction of the cost of pneumatic hardware and energy costs.

5. Cleaner grip

Some applications require a clean environment, otherwise air leakage may cause pollution. In this case, the electric gripper is the only feasible solution to pick up parts.
