[0003] The traditional spraying method is manual dust removal, which cannot ensure the cleanliness of large surface products.

[0004] Therefore, we proposed a positioning and spray-blocking tooling for the back structure of the profiling product to solve the above problems. Summary of the invention

[0005] The present invention aims at the problems raised in the prior art and proposes the following technical solutions:
