Meanwhile, a large-scale wind-power blade fiber laying manufacturing system is combined and comprises an ultraviolet light / electron beam in situ curing fiber laying head, a presoaking belt conveying system, a core mold supporting device, an integral wind-power blade core mold, a horizontal or vertical multi-freedom machine tool system and a laying control system so as to realize the automatic manufacturing of the integral large-scale wind-power blade.

Description

Technical field: [0001] The invention belongs to the technical field of wind power blade manufacturing, and relates to an integral wind power blade ultraviolet light / electron beam in-situ curing fiber laying and forming device and method. Background technique: [0002] As a renewable and clean energy, wind energy has been paid more and more attention by countries all over the world, so the manufacture of wind power equipment has become the key to the development of this green energy. In wind turbines, the manufacturing cost of wind power blades accounts for about 15% to 22% of the total cost; and because the blades are the key parts for capturing wind energy, they are also the most affected by the environment and the most vulnerable parts, the current wind power blades mainly use Manufactured by infusion and mold splitting process, the upper blade surface, lower blade surface, and girder are manufactured respectively by using infusion technology such as RTM; then, the girder...

AI Technical Summary

Problems solved by technology

This process method has the following problems: 1. Segmented bonding leads to low overall performance of the blade; 2. The blade layup cannot be optimally designed so that the advantages of composite materials cannot be fully utilized; 3. The degree of automation is low and the labor intensity is high; 4. Infusion defects such as poor glue, rich glue, and fiber buckling are not easy to control; 5. It is difficult to manufacture large-scale wind power blades, and auxiliary process equipment such as molds, ovens, and infusion systems are required

However, this technology also adopts resin infusion and molding and curing molding, which has problems such as low degree of automation, high labor intensity, and difficult control of resin infusion defects.
