Full-automatic annular iron core winding equipment

The utility model relates to a full-automatic annular iron core winding device which comprises a machine frame structure, a belt conveying structure is arranged on the machine frame structure, a speed reduction rod is fixed on the machine frame structure, an inner welding structure is arranged on the machine frame structure, and a control key is fixedly installed in the middle of the front face of the machine frame structure. After the winding machine is powered on, coiled equal-width steel belts are fixed to the belt unwinding disc and connected to the speed reduction rod through the belt conveying structure, the steel belt tension sensor and the belt unwinding disc have different unwinding speeds along with different tensions of the steel belts, when the number of winding turns reaches the outer diameter size of a product, an outer diameter detection signal is received and fed back to the PLC, and the winding shaft stops winding immediately; then the cutter structure automatically cuts off the steel belt, t
