Problems solved by technology

Common grid member laying heads mostly use rollers for refeeding, and this mechanism is prone to blockage of prepreg in the tow channel during the refeeding process; Chances are that the volume of the placement head becomes larger
When multiple placement heads are used for simultaneous laying, the spacing of the ribs will be limited by the size of the grid placement head structure, which limits the design space of the grid structure
The common grid laying head, the clamping and shearing mechanism needs to use the wire guide groove, which will cause some interference to the prepreg feeding

Abstract

The invention discloses a composite material grid component automatic laying head and a laying method. The composite material grid component automatic laying head comprises a shearing mechanism, a clamping mechanism, a re-conveying mechanism and a wire bundle guiding assembly. The composite material grid component automatic laying head further comprises a pressing air cylinder, a connecting frameand a balance adjusting mechanism, and the re-conveying mechanism comprises a rotating cylinder, a working compression roller, an auxiliary compression roller and a supporting frame. The supporting frame is rotatably connected with the connecting frame, and the working compression roller and the auxiliary compression roller are arranged in a spaced manner and are rotatably arranged on the supporting frame. The balance adjusting mechanism is arranged above the re-conveying mechanism, the balance adjusting mechanism comprises an adjusting rod, connecting rods and positioning elements, the adjusting rod is slidably arranged on the connecting frame, the two ends of the adjusting rod are arranged on the two connecting rods on the connecting frame in a sleeving manner correspondingly, the position of the adjusting rod is positioned through the positioning elements arranged on the connecting rods, and a cylinder body of the rotating air cylinder is arranged on the adjusting rod in a rotatablemanner. It is guaranteed that the compression rollers can be perpendicular to the laying plane in the laying process, blockage is avoided in the wire bundle re-conveying process, and a wire bundle channel is not occupied by the clamping mechanism and the shearing mechanism.

Description

technical field [0001] The invention relates to a composite material laying equipment and process, in particular to an automatic laying head and a laying method of a composite material grid member. Background technique [0002] Composite mesh members have the characteristics of high specific stiffness, high strength, and anti-vibration, and are widely used in aerospace, vehicles, medicine, and weaponry. Although composite mesh components have better performance than metal materials, their manufacture is more difficult and costly. At present, the manufacturing technologies of composite mesh components include automatic fiber winding, resin molding transfer molding, 3D printing and automatic laying technology. The automatic laying technology has the characteristics of high efficiency, high quality and low waste rate, and is especially suitable for the forming of complex mesh components. There is still a big gap between the automatic laying equipment of composite grid compone...
