  • Patent number: 10946585
    Abstract: A three-dimensional product manufacturing robot using a material constituted by plastic formable materials may be provided that includes: a head supply unit which includes an inlet into which the material is introduced; a transformer unit which includes a plurality of rollers guiding a moving direction of the material transferred from the head supply unit; and a head unit which discharges outwardly the material transferred from the transformer unit. As a result, the tension of a tow, i.e., a raw material can be adaptively controlled and the tow moving within the three-dimensional product manufacturing robot can be prevented from being solidified, cured or degraded. Also, the head unit can rotate precisely within a limited distance. Also, the rotation of the head unit does not accompany the rotation of the tow. That is, while the wheel assembly controls the rotation of the head unit, the tow which passes through the inside of the head unit can be discharged to the outside without rotation.
