Forming blind bond between components of wind energy plant rotor blade, involves applying adhesive on first and second adhesive surfaces of first and second components, placing components in final position, and curing second component

摘要

The method comprises applying an adhesive on a first adhesive surface of the first component and a second surface of second component, placing the two components in a final position, curing the second component, placing a mask on the first component, arranging first and second components in a predetermined position relative to one another, displacing the mask relative to the first component so that an edge of the mask bears on the second component when the two components are located in the predetermined position, and forming an adhesive layer on the first adhesive surface. The method comprises applying an adhesive on a first adhesive surface of the first component and a second surface of second component, placing the two components in a final position, curing the second component, placing a mask on the first component, arranging first and second components in a predetermined position relative to one another, displacing the mask relative to the first component so that an edge of the mask bears on the second component when the two components are located in the predetermined position, and forming an adhesive layer on the first adhesive surface before placing the two components in the final position, where an amount of the adhesive layer is predetermined relative to the edge of the mask. The displacement of the mask is performed by the second component while the two components are placed in the predetermined position. The mask comprises a fastener such as a vacuum cleaner that is attached on the first component and is slidably mounted on a plane perpendicular to the first adhesive surface oriented to a side face of the first component. A fastener holding force is increased after moving the mask and before forming the adhesive layer. The mask extends in longitudinal direction of first adhesive surface over a length of >= 1 m. The edge of the mask is adapted to a contour of second adhesive surface. The mask comprises a mark whose position is determined after the displacement of the mask, if a determined gap dimension lies in a predetermined range. The mask is removed before placing the two components in the final position. A side surface of the mask is arranged adjacent to the first adhesive surface after attachment of the mask on the first component. A contact surface of the fastener is arranged at a lateral distance from first adhesive surface after attachment of the mask. The application of the adhesive is carried out with a nozzle whose width corresponds to a width of the first adhesive surface. The step of forming the adhesive layer is carried out with a spatula. The arrangement of the two components in the predetermined position and in the final position takes place by folding of the two components with a folding device.
