Description

TECHNICAL FIELD

[0001] The application belongs to the technical field of wind turbine blade glue application, and particularly relates to an easy-to-disassemble wind turbine blade glue application device capable of automatically adjusting a glue type. BACKGROUND

[0002] The application of wind turbine blade bonding glue is a very important step in the production and manufacturing process of wind turbine blades, and is related to the strength and service life of the finished blade. At present, the production of wind turbine blades mostly adopts a manual glue application mode, which is low in efficiency. In order to improve the production efficiency of wind turbine blades, it is necessary to design and develop corresponding mechanical equipment and apply it to the glue application process of wind turbine blades. However, the structural glue used for bonding wind turbine blades has problems such as high viscosity and difficulty in cleaning, and if the residual bonding glue on the equipment is not cleaned, it will hinder the movement of the mechanism after solidification, affecting the reuse of the equipment. At the same time, in order to ensure the glue application quality, the glue layer adjusting mechanism of the glue application device needs to have good sealing performance to prevent the occurrence of glue leakage. At present, the research on the mechanization of wind turbine blade glue application has just started, and most of the existing design schemes lack consideration of the above problems.

[0003] The patent with the application number 202210016354.X and the name "an automatic glue application device for bonding wind turbine blade webs" adjusts the glue layer width and thickness through the transverse movement of the glue width adjusting mechanism and the vertical movement of the thickness adjusting mechanism, but there is a certain gap between the two adjusting mechanisms, which makes it difficult to ensure the sealing performance during the glue application process. The patent with the application number 202210255299.X and the name "wind turbine blade adjustable glue application device" has a more portable structure design, and also has width and thickness adjusting mechanisms and a closer fit between the two mechanisms, but the adjusting mechanisms are not easy to disassemble, making it difficult to clean, and if the residual bonding glue solidifies at the position where the two mechanisms contact each other, it will hinder the movement of the adjusting mechanism, thereby affecting the reuse of the device.
