Abstract

The invention discloses an automatic fiber laying system, the system comprises an automatic fiber laying device, a mold bearing device arranged corresponding to the automatic fiber laying device and acontrol subsystem, wherein the control subsystem comprises a compression roller pressure and laying track hybrid control module and a laying tension and speed decoupling control module which are usedfor controlling the automatic fiber laying device, and a temperature fuzzy self-adaptive control module for controlling the temperature of the mold bearing device. The invention further provides a planning method of the laying track of the automatic fiber laying device. According to the automatic fiber laying system and the planning method, precise control over laying process parameters can be achieved, so that laying quality is improved; and the laying track enables a cooperative mechanical arm to avoid singular poses, meanwhile, the joint stress condition of the cooperative mechanical arm is improved, interference is avoided, and the movement efficiency and safety are improved.

Description

technical field [0001] The invention relates to the technical field of laying composite materials. More specifically, the present invention relates to an automatic fiber laying system and a planning method for its laying trajectory. Background technique [0002] Carbon fiber composite materials have excellent properties such as high specific strength, high specific modulus, fatigue resistance and chemical corrosion resistance, and are widely used in aerospace, automobile, ship and sports equipment and other fields. Automatic lay-up technology is one of the important methods to achieve composite molding. According to the shape of fiber reinforced composite materials, automatic laying technology can be divided into two types: automatic tape laying and automatic wire laying. The automatic laying technology combines the advantages of automatic tape laying and fiber winding technology. The laying head combines the independent conveying of multiple prepreg tows in the winding te...
