Abstract

The invention relates to a yarn guide structure of fibers, in particular to a yarn guide device for fiber laying, and aims to solve the problems that a traditional floor type creel yarn guide mechanism limits the degree of freedom of motion of a robot, needs to use a multi-degree-of-freedom mold rotary table to increase the size of winding equipment and is high in equipment cost. The fixed end of the rotating mechanism is fixedly connected with the yarn guide frame, the rotating end of the rotating mechanism is connected with the fixed end of the pitching mechanism, the movable end of the pitching mechanism is connected with the fixed end of the swing mechanism, the movable end of the swing mechanism is connected with the yarn guide frame, and a fiber tow sequentially penetrates through the pitching mechanism and the swing mechanism from the rotating mechanism. The invention belongs to the processing field of fiber laying.

Description

technical field [0001] The present invention relates to a yarn guiding structure for fibers, in particular to a yarn guiding device for laying fibers. It belongs to the processing field of fiber placement. Background technique [0002] Carbon fiber composite components formed by automatic fiber placement technology have a wide range of applications in the aerospace field. Fiber placement technology is a molding method of resin-based fiber-reinforced composite materials, which lays fiber bundles on a mold according to a certain trajectory, and then solidifies and shapes to obtain the final product. With the development of robotics technology, 6-DOF serial robots have been widely used in the field of fiber placement. When it is on the wrist, the yarn storage capacity of the laying system will be limited by the rated load of the robot, and at the same time, the creel will occupy the space of the laying head, which will bring difficulties to the design of the laying head. The...
