The automatic powder spraying system can automatically complete the powder spraying of the parts after the loading is completed. At the same time, it also communicates with the PLC, automatically calls different robot paths and spraying programs according to the recognized part information, and automatically unloads and discharges the enclosed room. The function of suspending dust inside. The automatic powder spraying equipment has a PLC communication port, and communicates with the main PLC through the Profinet communication form of the station status and parts information. The surface of the part and the inside of the hole are evenly sprayed, which meets the requirements of Aicon scanning measurement.
　　The powder spraying system is a fully automated system, equipped with a dust collection and dust removal system to meet the national environmental protection and explosion-proof safety requirements. Equipped with an automatic workpiece up and down table and rotation system, with the robot to complete the automatic spraying, it can realize the automatic completion of the work task without being on duty for 24 hours. Adopt a closed system to avoid dust spillage, built-in station information sensor (including at least alcohol concentration monitoring, nozzle flow monitoring, ethanol capacity monitoring, exhaust pipe airflow monitoring, temperature monitoring, etc.), automatic feedback and warning information.
　　The sprayed workpiece is aluminum machined plate and shell parts, aluminum machined parts, 60mm~1500mm, the widest workpiece carrier is 1m. The thickness of the coating is less than 0.01-0.02mm (subject to the detection effect), and the process of one coating and one baking is adopted. The spray composition mainly consists of titanium dioxide (the main component titanium dioxide) + ethanol.
The spraying method adopts two modes: robot offline profiling spraying and manual trial teaching program. The spraying cycle is 1.5m workpieces for 2 minutes (including the time of up and down workpieces), and the conventional parts do not exceed 80 seconds. The powder spraying robot uses automatic powder spraying guns for powder feeding. High rate (built-in high-voltage package, central electrode, flat nozzle), uniform and stable powder output (three air intakes), smooth and uniform spraying surface, strong penetration, safe use (millijoule energy control). The spraying method uses an air spray gun, air jet atomization spraying, the paint supply system is a line-side small circulation system, the spraying ratio is set by the manual operation panel to set the ratio parameters (automatically added by ethanol), the quantity of oil powder is 1~2 (main titanium dioxide) Content + ethanol), the oil powder flow control is Cor-flo flow closed-loop control.
