The invention relates to the technical field of winding machines, and in particular to a compact transformer coil winding robot which comprises a bottom plate. The bottom plate is provided with a framework feeding mechanism, a fixing base, a discharging mechanism, a framework expanding mechanism, a rotating mechanism, a first moving mechanism, a winding arm, a wire feeding mechanism, a wire cutting and bending mechanism, a second moving mechanism and an ejecting mechanism used for moving a framework of the framework feeding mechanism to the framework expanding mechanism. The coil framework isfixed through the framework expansion mechanism, fixing is stable and reliable, and the situation that the product quality is reduced due to the fact that the framework loosens and shifts in the coilwinding process is prevented; an included angle of 20 degrees is formed between the coil framework and the bottom plate, so automatic feeding and discharging of the coil framework are facilitated, andproduction efficiency is improved; and the wire ends are automatically fixed, so that the problem of poor consistency of manually fixed products is avoided, and meanwhile, the production efficiency is also greatly improved.
