[0002] With the growing global demand for clean energy, wind power, as a clean, renewable energy source, has gained widespread adoption worldwide. Wind turbine blades are key components of wind turbines, and their performance directly impacts power generation efficiency and service life. Edge grinding is a crucial step in blade manufacturing. High-quality edge grinding not only improves blade aerodynamic performance but also extends blade service life.

[0003] Traditional blade edge grinding methods mainly rely on manual operation or semi-automatic equipment, which has the following problems:

[0020] The vibration and noise generated during the grinding process not only affect the working environment, but may also lead to a decline in grinding quality.

[0021] Long-term exposure to high noise environments may damage the operator's hearing. Utility Model Content
