Description

Technical Field

[0001] This application belongs to the technical field of wind turbine blade production, and specifically relates to a glue application device for wind turbine blades with an asymmetric and automatically adjustable glue type. Background Technique

[0002] Currently, China's emphasis on the wind power generation industry has been continuously increasing, which undoubtedly puts more stringent requirements on the production efficiency and quality of wind turbine blades. In the production process of wind turbine blades, bonding the two halves of the blade with adhesive is a key step. Especially the web, as the main load-bearing component of the wind turbine blade, its bonding quality directly affects the structural strength of the entire wind turbine blade. At present, the glue application operation of wind turbine blades mainly relies on manual operation, and the technical level and quantity of workers have a decisive impact on the efficiency and quality of glue application; while manual control of the glue application thickness and width often leads to uneven or excessive glue application, which not only affects the glue application quality but also causes waste of raw materials. Therefore, developing an advanced device that can automatically adjust the glue application form according to the glue application process requirements is of crucial significance for improving the glue application efficiency and quality.

[0003] For the patent with the application number 202311729625.7 and the name "A Glue Application Device for Wind Turbine Blades with Automatic Glue Type Adjustment According to Glue Application Process", its main components include a glue application box, a glue width and thickness adjustment mechanism, and a length measurement feedback control component. The length measurement feedback control component controls the movement of the glue width and thickness adjustment mechanism by measuring the traveling distance of the glue application device, so as to adjust the left-right width and up-down thickness of the glue outlet, so that the size of the glue type meets the requirements. However, the length measurement feedback control adopted by this device cannot adjust the glue type width in real time, resulting in a deviation between the profile of the applied adhesive and the actual contour of the blade bonding surface, so the glue type size cannot accurately match the glue application process requirements.

[0004] For the patent with the application number 202411456446.5 and the name "A Glue Application Device for Wind Turbine Blades", its main components include a glue storage bin, two glue width adjustment plates, a glue thickness adjustment plate, and a control component. The control component controls the movement of the glue width adjustment plate and the glue thickness adjustment plate to adjust the left-right width and up-down thickness of the glue outlet, so that the size of the glue type meets the requirements, greatly improving the efficiency of glue application for wind turbine blades and controlling the glue application amount at the same time, saving the cost of glue application for wind turbine blades. The structure of this patent includes a glue application box, a scraper, two side plates, and a control device. Its scraper can move up and down to change the thickness of the glue outlet, and the two side plates can move symmetrically left and right to change the width of the glue outlet. However, the shape of the scraper of this patent is fixed, and the two side plates must move symmetrically, so its glue application size is relatively single and cannot meet various different glue types in actual production.
