The invention relates to a gumming method for an amorphous alloy three-dimensional roll iron core. The method is carried out in a gumming device for the amorphous alloy three-dimensional roll iron core. According to the gumming method provided by the invention, epoxy resin automatically attaches to the bottom end face of the iron core after the amorphous alloy three-dimensional roll iron core is suspended into the gumming device. The time of iron core turning and secondary epoxy coating curing can be eliminated. The production efficiency of the amorphous alloy three-dimensional roll iron core is improved. The influence of turning on the performance of the amorphous three-dimensional roll iron core is reduced. The method is used to apply the epoxy resin to the surface of the amorphous alloy three-dimensional roll iron core. The problems of low gumming efficiency and degraded performance in the prior art can be solved.
