Composite material fiber winding forming device based on robot

Abstract

The invention discloses a composite material fiber winding forming device based on a robot. The composite material fiber winding forming device is characterized by comprising a multi-degree-of-freedomindustrial robot body, a fiber winding head device and a core mold rotating device, wherein the core mold rotating device comprises a rotating winding core mold and a support used for supporting thewinding core mold, the fiber winding head device comprises a fiber releasing device used for releasing a fiber material, a fiber wheel train adjusting module used for adjusting a fiber material releasing path, and a fiber tension detecting device used for detecting the tension of the fiber material and feeding back the tension to the fiber releasing device, and the fiber releasing device releasesthe fiber material to the winding core mold for winding through the fiber wheel train adjusting module. According to the winding forming device, constant-tension winding of the fiber material on the winding core mold along a designed path is achieved, the adaptability of the winding device to a product structure is improved, fiber line type design constraints are reduced, and the structural performance of a fiber winding forming product is improved.
