Abstract: The adhesive coating operation of wind turbine blades is one of the core steps in the main forming process of wind turbine blades, which directly affects the service life and power generation efficiency of the finished blades. In current blade production enterprises, manual hand-held scraper pushing of adhesive is still used, which results in poor adhesive quality and is greatly affected by employee proficiency. The matching rate between trial mold data and adhesive layer parameters is low, leading to serious adhesive waste and high labor costs. To solve the above problems, this article comprehensively considers the actual operational needs and functional analysis solutions on site. The design adopts the construction form of a gantry style mechanical arm, an industrial six axis robot, and intelligent adjustable adhesive boots. The programmable logic controller (PLC) is used to achieve collaborative control between various components, thereby realizing fully automatic adhesive pushing operation of large wind turbine blades. After the design was completed, experiments were conducted using the developed prototype, and the results showed that the application of the modified equipment can effectively reduce labor costs, improve operational efficiency, enhance adhesive quality, and reduce the amount of adhesive used.
