Automatic prepreg tape laying head and guide rail bracket

Abstract

The invention relates to an automatic prepreg tape laying head and a guide rail bracket. The guide rail bracket comprises two U-shaped supporting columns, a rolling cross beam and a laying head fixing device; the two U-shaped supporting columns are symmetrically arranged on the two sides of the automatic prepreg tape laying head; a bracket guide rail is arranged in the top of each U-shaped supporting column; the rolling cross beam is fixed to a first rolling wheel through a first connecting shaft; the first rolling wheel can roll in the bracket guide rail; a cross beam guide rail is arranged in the rolling cross beam; an outer cover is arranged on the outer side of the automatic prepreg tape laying head and connected with the rolling cross beam through a laying head fixing device; and the automatic prepreg tape laying head comprises a feeding mechanism, a laying mechanism, a cutting mechanism, a guiding mechanism and a reversing mechanism. The automatic prepreg tape laying head does not need to be placed layer by layer in a single time, so that the production efficiency is greatly improved, and meanwhile, idle stroke return stroke or turning around is not needed, so that the laying time is saved.

Description

technical field [0001] The invention relates to the field of automatic laying, in particular to an automatic laying head and a guide rail support for prepreg tape. 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] 1. The automati...

AI Technical Summary

Problems solved by technology

[0005] 1. The automatic laying technology of the prior art is to lay the prepreg tape layer by layer on the surface of the mold. After laying several layers, the composite material component reaches a certain thickness. Therefore, for laying multi-layer prepreg tape The mold can only be stacked layer by layer, and the laying efficiency is low

[0006] 2. At the end of laying each path, the laying mechanism must go back and forth or turn around to re-lay the previous laying path or lay the next path. Therefore, during the automatic laying process, the laying mechanism needs to Multiple round trips or U-turn laying, wasting a lot of time

[0007] 3. The existing cutting method is the contact cutting of the cutting board and the anvil knife. Since the strip material is moving during the laying process, the contact cutting is easy to cause adhesion and pulling of the anvil knife and the surface of the strip material, which will cause unnecessary damage to the strip material. The tension will affect the laying effect of the tape at the moment of cutting
