AI Technical Summary

Technical Problem

Existing technologies suffer from loss of conformity accuracy and sheet displacement during the stacking, palletizing, bundling, and hoisting of fiber pultruded sheets, resulting in poor conformity of the main beam and consuming a lot of manpower and time, which affects the quality and efficiency of blade manufacturing.

Method used

An automated pultrusion beam stacking conformal automation device is adopted, including a bearing platform, a spray curing system and a fabric laying system. The device achieves automated spraying, curing and fabric laying through a spray nozzle, an LED UV curing light source and a fabric laying cylinder. The device uses an adjusting screw structure and a motor drive to achieve the bonding and movement of the sheet material, ensuring precise conformal shaping.

Benefits of technology

It has enabled automated production without human intervention, which has improved production efficiency, reduced labor costs, reduced material consumption, and enhanced safety and production quality.

Abstract

The present application relates to a kind of automatic equipment and method of pultrusion girder stack profile. The equipment includes: bearing platform, including bearing base plate, and profile assembly above bearing base plate and with the arc surface of different pultrusion plate is fitted;Glue spraying curing system is moved along the direction of two sides of bearing base plate, including several glue spraying heads arranged above profile assembly, and curing assembly arranged above profile assembly;And cloth laying system is moved along the direction of two sides of bearing base plate, including cloth laying shaft cylinder arranged above profile assembly. The method is that cloth laying shaft cylinder is laid to pultrusion plate placed above profile assembly, glue spraying head is sprayed to cloth on pultrusion plate, and curing assembly is used to cure glue and cloth. Compared with prior art, the present application has the advantages of automatically forming pultrusion girder, saving material, saving labor cost, and high safety and high production efficiency.
