Problems solved by technology

[0002] A wind turbine is a turbine powered by wind energy. In the manufacture of wind turbine blades, many processes, such as the laying of fiber cloth, are still done manually by workers. The problem is that workers lack sufficient guidance in these manual procedures. Such as the laying position of the fiber, etc., thus making the manufacturing efficiency lower and the quality lower

Embodiment 2

[0045] In this embodiment, the first auxiliary system 31 includes two first laser projection devices 310 respectively located on both sides above the blade mold 20, and two first optical imaging devices 311 respectively located on both sides above the blade mold 20. A laser projection device 310 and the first optical imaging device 311 are located at different positions along the longitudinal axis L of the blade mold 20 . In practice, in order to accurately shoot laser projection images and the blade manufacturing process, the camera device needs to use a telephoto lens. Due to the limited field of view, and considering the small area near the end surface of the root of the blade, the root can be arranged in the camera The proximal section of the area, the middle or tip of the blade is arranged at the far end of the imaging area. To sum up, in this embodiment, preferably, the first optical imaging device 311 is located closer to the mold root 22 of the blade mold 20 , and the ...

Embodiment 3

[0049] In this example, if Figure 4 and Figure 5 As shown, the blade mold 20 is divided into adjacent first section 20A and second section 20B, wherein the first section includes the mold root 22 of the aforementioned blade mold 20, and the aforementioned first auxiliary system 30 is used for the second A section 20A is projected and imaged. In addition, the blade manufacturing auxiliary system 30 also includes a second auxiliary system 32. The second auxiliary system 32 projects and images the second section 20B and includes at least one second laser projection device 320 and At least one second optical imaging device 321 and a second laser projection device 320 are installed above the blade mold 20 for projecting second operation guide graphics and structured light for assisting three-dimensional measurement on the blade. The second optical imaging device 321 is installed above the blade mold 20 to obtain the second operation guide pattern projected on the blade, the stru...

Embodiment 4

[0055] In this implementation, the blade manufacturing auxiliary system 30 also includes a control device (not shown), which is connected in communication with the first laser projection device 310 and the first optical imaging device 311 to read the blade drawing information , and obtain the three-dimensional model of the blade and / or the blade mold 20 in the blade manufacturing process through the imaging information collected from the first optical imaging device, and based on the blade drawing information and the three-dimensional model, control the first laser projection device 310 to project the required The first operation guide graphic. Wherein, the imaging information includes imaging of structured light for assisting three-dimensional measurement and imaging of leaves under ambient light. Further, the imaging information may also include a first operation guide graphic, and the position of the first operation guide graphic is adjusted based on an error of the project...

Abstract

The invention relates to a wind turbine blade auxiliary manufacturing system and device. The system comprises a first auxiliary system which is installed above a blade mold; the first auxiliary system comprises a first laser projection device used for projecting a first operation guiding graph and structured light used for assisting three-dimensional measurement on a blade, and a first optical imaging device used for obtaining the first operation guiding graph and a structured light image projected on the blade and an image of the blade under irradiation of ambient light; and the first laser projection device and the first optical imaging device are correspondingly arranged in pairs. Compared with the prior art, the system has the advantages of being high in projection precision, free of auxiliary positioning of a reflection target, free of invasion to the original blade production and manufacturing process and the like.
