Engine blade machining is a complex and elaborate process. High quality engine blades can be manufactured by casting, roughing, heat treating, finishing, inspection and quality control, surface treating and assembling, etc. These blades play an important role in the engine, affecting the performance and reliability of the engine. Therefore, during blade machining, the quality and process requirements of each process step need to be tightly controlled to ensure that the final quality and performance of the blade meets design requirements.
The surface treatment process is to treat the blade to prevent corrosion, increase lubricity and improve appearance by electroplating, spraying or coating and other processes in order to improve the surface quality and corrosion resistance of the blade. The surface treatment can improve the service life and performance of the blade, and is an indispensable procedure in the processing of the engine blade.

The regular shapes that are not common for aerospace engine blades, when they are surface sprayed using conventional spraying processes or devices, tend to suffer from several problems:
1. coating splashing easily occurs in the spraying process, so that the resource waste and the environmental protection problem are caused.
2. The problem of inconvenient clamping and unloading dismantlement of the material loading of engine blade. Specifically, the special shape of the engine blade and the spraying processing mode can cause the problem that the clamping position is difficult to select in the clamping process.
3. Because of the special appearance characteristics of the engine blade, when the surface of the engine blade is sprayed by adopting a traditional spraying mode, the thickness of a spraying coating is greatly different due to the uncertainty of a spraying mechanism and a spraying position on the distance, so that the problem of uneven spraying is caused; in addition, in the spraying process, a spraying dead angle is easy to appear.
4. If the paint sprayed on the surface of the engine blade is not dried in time, the paint flows, and the integral spraying effect is affected.
In summary, it is clear that the prior art has inconvenience and defects in practical use, so that improvement is needed.
