The invention relates to the field of circuit board production equipment, and discloses a spherical circuit transfer printing machine. The spherical circuit transfer printing machine comprises a spherical base that can freely rotate. The spherical base is driven by a plurality of friction wheels that can be precisely controlled. A printing mechanism, a powder spraying mechanism, and a mould are arranged on the base. The powder spraying mechanism sprays a layer of iron powder on the base, and due to the iron powder, demoulding becomes easy. The printing mechanism draws circuits on the rotating base by using melted printing materials, and then the drawn circuit is transfer-printed to a base material in the mould so as to produce the spherical circuit boards. The invention provides a spherical circuit transfer printing machine to produce spherical circuit boards.
