For the preparation of carbon fiber composite blades as non-rotational parts, this paper divides the part model into several ellipsoidal surfaces, ellipsoidal surfaces and planar surfaces, and calculates the geodesic equations of ellipsoidal surfaces and ellipsoidal surfaces by the method of differential geometry, and then designs a six-degree-of-freedom wrapping robot for complex surface processing according to the requirements of the wrapping molding process. Then a virtual prototype is designed according to the requirements of complex surface machining, and a simulation program of winding carbon fiber prepreg tape on the blade by a six-degree-of-freedom winding robot is generated through the joint trajectory simulation of Matlab and Adams, and the feasibility of the winding molding process is verified through the trajectory simulation.
