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

1. Control the position of the gripper

By using coded motors and appropriate control schemes, electric clamps can be used to determine the position of the jaws. On the contrary, for traditional grippers, it is usually necessary to maintain the entire stroke. When using an electric gripper, it is possible to flexibly approach the part with only a small necessary gap and then perform a small stroke to pick it up. Partially opening and closing can help select a larger range of part sizes without affecting the production cycle.

2. Check the grip strength

Using an encoder, you can determine if the gripper has picked up the part. Some electric pliers will send this information back to the robot controller. In many applications, it is necessary to check the handle to prevent errors. Doing so at the gripper level can avoid placing other sensors in the loop, simplify integration, and reduce overall costs.

3. Control grip and speed

Due to the proportional relationship between motor current and applied torque, the clamping force exerted by the paper teeth can be controlled. The closing speed is also the same. For example, this may help with handling fragile parts.

4. Tracheal free: Save electricity and maintenance costs

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

5. Clean the handle

Some applications require a clean environment, otherwise air leaks may cause pollution. In this case, electric grippers are a feasible solution for picking up parts.

The above are the advantages of servo electric grippers, among which the main features of the robotic gripper are: driven by a motor, it can clamp and release the gripper fingers, and the positioning point and clamping force are controllable; By using PLC, industrial computer, microcontroller, and motion controller, the grasping and positioning functions of objects are achieved. It is a flexible execution terminal for mechanical equipment.

Mechanical grippers are used in the field of industrial automation. Some models have self-locking mechanisms to prevent damage to workpieces and equipment caused by power outages, which are safer than pneumatic grippers. The opening and closing of the gripper has programmable control function, realizing multi-point positioning, and can have more than 256 stopping points; Acceleration and deceleration can be controlled, and the impact on the workpiece can be reduced to a low level. Pneumatic grippers are a process of impact that exists in principle and is difficult to eliminate. The clamping force of the mechanical gripper can be adjusted and closed-loop control of force can be achieved. The clamping force accuracy can reach 0.01N, and the measurement accuracy can reach 0.005mm. Widely used in industrial automation, mobile phones, televisions, home appliances, and automotive/automotive parts manufacturing enterprises.
