Automatic prepreg tape laying device

Abstract

The invention discloses an automatic prepreg tape laying device. The device comprises a feeding mechanism, a laying mechanism, a cutting mechanism, a guiding mechanism and a reversing mechanism, and the feeding mechanism comprises a left tape coil, a right tape coil, a first clamping roller pair, a second clamping roller pair, a first prepreg tape and a second prepreg tape. The laying mechanism comprises a first heating roller pair, a first pressing roller, a first laying roller pair, a second laying roller pair, a second pressing roller and a second heating roller pair, the guiding mechanism comprises a first guiding mechanism, a third guiding mechanism and a second guiding mechanism, and the cutting mechanism comprises a double-head laser cutter and a supporting frame. The reversing mechanism comprises a first reversing mechanism and a second reversing mechanism. According to the automatic prepreg tape laying device, single laying layer by layer is not needed, the production efficiency is greatly improved, meanwhile, idle stroke returing 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 device 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 automatic laying technology of ...

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
