The invention provides an intelligent sewing device and system. The device comprises an industrial sewing machine for sewing cloth, a mechanical arm clamp, an industrial robot, a main controller and a sewing vision unit. The industrial robot operates the mechanical arm clamp for sewing matching. The industrial sewing machine, the mechanical arm clamp, an equipment protecting device and the industrial robot are connected through the main controller which then carries out control. The sewing vision unit is used for shooting sewing workbench images and obtaining cloth images. The system comprises a plurality of intelligent sewing devices, main controllers, exchangers, feeding controllers, loading devices, feeding devices and centralized control computers. The main controllers and the exchangers are in communication connection with the intelligent sewing devices. The feeding controllers are in communication connection to the exchangers. The loading devices are connected with the feeding controllers. The feeding devices are used for placing of cloth by the loading devices and conveying the cloth to the intelligent sewing devices. The centralized control computers are in communication connection with operation man-machine interaction platforms of the exchangers. Through the system, automatic loading, feeding and sewing are achieved, during a sewing process, the cloth can be used for locating or correcting an algorithm, sewing is accurate, and working efficiency and product yield are greatly improved.
