When the motor receives the starting signal of the control system, it will start rotating. The speed reducer is connected between the motor and the transmission device, and is used for reducing the rotating speed of the motor and increasing the torque. This makes the transmission device more efficient in power transmission, while reducing wear and energy consumption. The transmission device converts the rotating motion of the motor into the opening and closing motion of the clamping jaw. This usually involves a series of mechanical structures such as gears, chains or belt drives. Under the drive of the transmission device, the clamping jaw will realize the opening and closing action. The clamping jaw is internally equipped with precise sensors for real-time monitoring of the state of the clamping jaw and the position of the object. The control system is the core part of the rotating gripper, and is responsible for receiving and processing information from the sensors and other input devices.
