Abstract: Based on the analysis of the structural features and working principle of the laying equipment, combined with the problems and shortcomings of the existing laying equipment in China, this article designs a composite processing device that combines placement and cutting by PTC Creo Parametric. The device not only enables basic 8 tow placement but also adds a cutting mechanism, it allows the laying and cutting to work in harmony and realizes the computer-defined three-dimensional solid forming. This paper adopts a stacking method to design the cutting module and the module of clamping and re-feeding. It uses press shoes to design a compaction module which can realize individual control of multiple tows and is suitable for laying complex workpieces. It adopts the ultrasonic cutting method to trim and cut the boundary of the carbon fiber ply after laying. This paper also simulates the model established by ADAMS and verifies the stability of the device movement. The various components in the device are modularly designed and have certain expansibility.
