Servo electric gripper motion control

Servo electric gripper is a common industrial robot equipment, which has a wide range of applications. In practical applications, precise motion control plays an important role in the performance and efficiency of the gripper. This paper will discuss the motion control of servo electric gripper, including its principle, control method and application.

Servo electric gripper is a mechanical and electrical integration product using the motor as the power source. Its basic principle is to use the rotating torque of the motor to drive the mechanical parts to achieve the operation of clamping and loosening the workpiece. Servo electric gripper is usually composed of motor, reducer, sensor, controller and gripper body. Among them, the motor is responsible for providing power, the sensor is used to monitor the position of the claw, speed and strength and other parameters, the controller according to the sensor feedback signal and preset control algorithm to control the motor speed and steering, so as to achieve the motion control of the claw.

The control method of servo electric claw

1. Position control The position control of servo electric gripper is to control the gripper to stop or move at a specific position. Position control can be realized through closed-loop control, that is, the sensor is used to monitor the position information of the claw, and the target position is compared, the error is calculated, and the control signal is adjusted according to the error to drive the motor to achieve accurate position control.

2. Speed control The speed control of the servo electric gripper is to control the motion speed of the gripper. Speed control can be realized by closed - loop or open - loop control. The closed-loop control method usually uses the speed feedback sensor to monitor, so as to realize the precise control of the motor speed. The open loop control mode realizes the control by driving the motor with preset control signal.

3. Force control The force control of the servo electric gripper refers to the control of the gripper's clamping strength. Force control can be realized by closed - loop or open - loop control. The closed-loop control method usually uses force sensor to monitor, so as to achieve accurate control of the clamping force of the gripper. The open loop control mode realizes the control by driving the motor with preset control signal.

The application of servo electric claw

Servo electric gripper is widely used in automatic production lines and robot systems, mainly used for clamping, transporting and placing workpiece operations. Specific applications include automobile manufacturing, electronic manufacturing, food processing and other industries.
