[0002] In the field of automation industry, grippers for picking up workpieces are often installed on robot terminals. The most widely used are pneumatic grippers, which use compressed air as power. Their working principle is to use an air compressor to convert other original output mechanical energy into air pressure energy, and then, under the action of the control element, the pressure energy is converted into mechanical energy in the form of linear motion or rotational motion through the actuator, thereby completing various actions. When positive pressure is input, the gripper is tightened to grasp, and when negative pressure is input, the gripper is loosened to release the object.

[0003] Traditional four-finger mechanical chucks are mostly pneumatic jaws, which have certain defects when used:

[0004] 1. Traditional pneumatic grippers are mainly driven by gas, which is often prone to accidental leakage and unstable air pressure.

[0005] 2. The power of the pneumatic gripper needs to be provided by compressed air, and the control of the cylinder movement needs to be controlled by pneumatic control elements, which increases the cost of using the equipment.

[0006] 3. Pneumatic grippers use compressed air as power, so they will produce exhaust noise. Utility Model Content

[0020] Working principle: During use of the utility model, the motor is first energized. When current flows through the stator winding on the stator core 11, the stator winding generates a vector magnetic field, which drives the rotor core 7 to rotate by an angle. A pulse signal is input to the motor, and the rotor core 7 rotates in one direction.
