Automatic laying method

Abstract

The invention provides an automatic laying method, which comprises the following steps that step 1, an automatic prepreg tape laying head and a guide rail support are arranged; step 2, a prepreg tape coil is installed, and a tape head is fixed; step 3, the automatic prepreg tape laying head is laid in the forward direction along a beam guide rail; step 4, when laying on a current path is finished, laser cutting is carried out on a first prepreg tape and a second prepreg tape by controlling a double-head laser cutter; step 5, a reversing mechanism carries out reversing; step 6, the automatic prepreg tape laying head is laid reversely along the cross beam guide rail; and step 7, when laying on the current path is finished, the double-head laser cutter is controlled to perform laser cutting on the first prepreg tape and the second prepreg tape, and the steps 2-5 are repeated until the laying is finished. According to the automatic laying method of the invention, single laying layer by layer is not needed, the production efficiency is greatly improved, idle stroke return stroke or turning around is not needed, and the laying time is saved.

Description

technical field [0001] The invention relates to the field of automatic laying, in particular to an automatic laying method. Background technique [0002] The automatic laying technology has the characteristics of high efficiency, high quality, high reliability and low cost. It is especially suitable for the manufacture of large-scale components, which reduces the number of assembled parts, saves manufacturing and assembly costs, and greatly reduces the scrap rate of materials. It is widely used in the manufacture of aerospace high-performance composite structures. [0003] The automatic laying technology uses the prepreg tape as the raw material. After being heated, it is directly laid on the surface of the mold or the upper layer of prepreg tape under the action of the pressure roller to realize the automatic forming of the composite material layup. [0004] The disadvantages of the prior art are as follows. [0005] The automatic laying technology of the prior art is to ...

AI Technical Summary

Problems solved by technology

[0005] The automatic laying technology of the prior art is to lay the prepreg tape layer by layer on the surface of the mold, and after several layers of laying, the composite material component reaches a certain thickness. , can only be stacked layer by layer, and the laying efficiency is low

[0006] At the end of laying each path, the laying mechanism must go back and forth or turn around to lay the last laying path again, or to lay the next path. Therefore, in the automatic laying process, the laying mechanism needs to Back and forth or U-turn laying, wasting a lot of time

[0007] The existing cutting method is contact cutting with cutting board and anvil knife. Since the strip material is moving during laying, contact cutting is easy to cause adhesion and pulling of the anvil knife and the surface of the strip material, and generate unnecessary tension on the strip material , affecting the laying effect of the strip material at the moment of cutting
