The invention relates to an intelligent automatic bobbin winder which comprises a machine frame. A thread breaking prevention device, a thread feeding wheel, a tension control length measuring mechanism, a yarn swinging device and a thread winding device which are sequentially arranged in the yarn moving direction are installed on the machine frame. The thread winding device comprises a rotating shaft which is arranged on the machine frame in a rotating mode, two barrel arms which are arranged on a spindle, and driving rollers. The barrel arms are provided with supporting pieces for yarn barrels. The machine frame is provided with a power box body and a bracket for the driving rollers. A rotating power mechanism for the driving rollers is arranged inside the power box body. The yarn swinging device comprises a swing rod, a cylindrical cam and a guide rod. A yarn guide ring and a swing shaft are arranged at the two ends of the swing rod correspondingly. The swing shaft is connected withthe machine frame in a rotating mode. The rotating power mechanism drives the cylindrical cam to rotate around the axis through a transmission device. The cylindrical cam is provided with a curve groove. One end of the guide rod abuts against the curve groove through a guide sliding block, and the other end of the guide rod is fixedly connected with the swing shaft. The intelligent automatic bobbin winder is simple in structure, the bobbin forming quality is high and maintenance cost is low.
