AI Technical Summary

Technical Problem

The challenge in manufacturing wind turbine blades is the precise positioning and adherence of preform elements on a blade mold, as adjacent elements with angled surfaces tend to slide off due to their weight, leading to unwanted overlap and making precise placement cumbersome and time-consuming.

Method used

A method utilizing an assembly rack with supporting elements arranged in a geometry corresponding to the desired section geometry of the shell section, where preform elements are arranged and adhered to each other using gripper elements and heating means to form a shell section, which is then turned upside down and lifted onto the blade mold using the assembly rack as a lifting yoke.

Benefits of technology

This method ensures precise positioning and adherence of preform elements, preventing sliding and overlap, and simplifies the handling and placement of shell sections on the blade mold, thereby enhancing the efficiency and accuracy of wind turbine blade manufacturing.

Abstract

Method for arranging a shell section on a blade mold for manufacturing a blade or a half shell of a blade of a wind turbine, and assembly rack for arranging a shell section on a blade mold for manufacturing a blade or a half shell of a blade of a wind turbine Method for arranging a shell section (20, 35, 53), particularly a half shell section, on a blade mold (22) for manufacturing a blade or a half shell of a blade of a wind turbine, wherein the method comprises the steps: - providing several preform elements (21, 36, 51), each comprising a stack of layers of fiber mats fixated to each other, - arranging the preform elements (21, 36, 51) on supporting elements (8) of a frame (2, 50) of an assembly rack (1) and adhering the preform elements (21, 36, 51) with each other to constitute the shell section (20, 35, 53), - gripping the shell section (20, 35, 53) to the frame (2, 50) by gripper elements (17) of the assembly rack (1), - turning the frame (2, 50) and the shell section (20, 35, 53) upside down by at least one swivel joint (26) which rotatably connects the frame (2, 50) with a stand (3) of the assembly rack (1), - lifting the shell section (20, 35, 53) and placing it on the blade mold (22), wherein the frame (2, 50) being disconnected from the stand (3) is used as a lifting yoke.
