When processing circuit boards, it is necessary to pre-apply a special glue to the position of the surface patch to protect the circuit board. When applying the glue, a coating machine is needed. The coating machine is an automated mechanical equipment that specifically controls the fluid and applies the fluid to the surface of the product.

[0003] When people use coating machines to process circuit boards, in order to coat the circuit boards in their entirety, they will turn the circuit boards over after processing one side of the circuit boards, so as to coat the other side. When turning over the circuit boards, people usually do it manually. Since the paint just covering the circuit boards has not dried completely, it is very easy to get on people's hands, which will affect the coating quality of the circuit boards and reduce the neatness of the coating work.
