[0002] In the process of the vigorous development of modern spraying industry, the spraying production positioning mechanism as a key component to ensure the spraying quality and production efficiency directly affects the appearance quality, coating uniformity and stability of the production process. At present, most traditional positioning mechanisms adopt simple mechanical clamps or manual positioning methods, which are difficult to realize accurate positioning and stable clamping when facing various shapes and sizes of workpieces to be sprayed. For example, when spraying some products with complex curved surfaces or high-precision size requirements (such as automobile parts, electronic product housings, etc.), due to positioning deviation, the spraying coating thickness may be uneven, the edge coverage may be incomplete or the spraying may be missed, which seriously affects the appearance quality and protection performance of the products. In addition, inaccurate positioning may also cause the workpiece to shift or sway during spraying, resulting in scratches, sagging and other defects on the coating surface, increasing the scrap rate and reducing the production efficiency.
