Arm sewing synchronous device and method

Abstract

An arm sewing synchronous device for use in conjunction with a servo sewing machine, and the arm sewing synchronous device includes a driver, a control unit and a robot arm. The driver drives the servo sewing machine to drive a needle insertion shaft. The control unit is electrically connected to the driver in a closed-loop, the control unit receives a first feedback signal from the driver, and sends a first command signal to the driver. The robot arm is electrically connected to the control unit in a closed-loop, the control unit receives a second feedback signal from the robot arm, and sends a second command signal to the robot arm, where the control unit synchronously receives the second feedback signal and sends the first command signal through a calculation method.
