Abstract

A double-layer bidirectional laying method of a prepreg tape automatic laying device. The prepreg tape automatic laying device includes a feeding mechanism, a laying mechanism, a cutting mechanism, a guiding mechanism and a reversing mechanism. The two-way laying method includes the first laying mechanism laying the first layer, and the second laying mechanism at a distance behind the first laying mechanism then laying the second layer, so that two layers of prepreg tapes can be laid simultaneously, and the Reversing the direction of the mechanism, respectively guiding the first prepreg tape and the second prepreg tape to be conveyed to the first pressing roller and the second pressing roller in the opposite direction to the previous laying process, and the next laying process can be carried out. Realize two-way laying. The double-layer two-way laying method does not need to lay one by one layer by layer, which greatly improves the production efficiency, and at the same time, it does not need to return or turn around in an empty way, which saves the laying time.

Description

technical field

[0001] The invention relates to the field of automatic laying, in particular to a method for automatic laying of prepreg tapes. Background technique

[0002] The automatic laying technology has the characteristics of high efficiency, high quality, high reliability and low cost, and is especially suitable for the manufacture of large-sized components, reducing the number of assembled parts, saving manufacturing and assembly costs, and greatly reducing the waste 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 heating, it is directly laid on the surface of the mold or the upper layer of the prepreg tape under the action of the pressing roller to realize the automatic forming of the composite material laying.

[0004] Disadvantages of the prior art:

[0005] 1. The automatic laying technology of the prior art is to...
