the double pressing roller of automated prepreg placement apparatus for composite materials

摘要

The present invention relates to a double compression roller of a prepreg automatic lamination device for a composite material. The double compression roller is applied to a prepreg automatic laminating device attaching prepreg, to which heat is applied, when a mold is pressed. The double compression roller comprises a front roller and a rear roller connected to the front roller in parallel with a link; the rear roller constitutes a large number of segment disks with pressurization holes formed therein; a tube is formed in the pressurization hole; and a cylinder is combined with the link. According to the present invention, prepreg can be closely attached to a mold by the double compression roller regardless of the surface structure of the mold since the prepreg is pressed by the front roller, the rear roller and the cylinder to adhere closely to the mold and the segment disk of the rear roller pressurizes with a tube, into which fluid is injected, while changing corresponding to the shape of a mold surface despite a bending or irregularities on the mold surface.
