This invention discloses an automated process control system for ceramic coatings with prebaked anodes designed for oxidation prevention, relating to the field of spraying control technology. The system includes a prebaked anode spraying pretreatment module, a spraying fluctuation monitoring module, a spraying fluctuation correction and optimization module, and a spraying post-treatment module. This invention uses an automated spraying robot to spray prebaked anode carbon blocks. Based on the robot's built-in driver, it monitors the fluctuation of the end spray gun in real time, enabling preliminary judgment of spray gun movement fluctuations and determining whether to perform auxiliary judgment. Then, based on the results of the auxiliary judgment, it determines whether to perform robot spraying correction. Finally, the sprayed prebaked anode carbon blocks are transported to a flash-drying area for flash-drying before primer spraying. This improves the adhesion of the ceramic coating to the prebaked anode, solving the problem in existing technologies where inaccurate control of the ceramic coating affects the oxidation prevention effect of the prebaked anode carbon blocks.
