Automated Paint Spraying

A smooth, consistent finish is critical when painting vehicles. Automated paint spraying has made the process easier for manufacturers. Not only does a high-quality paint job look great, but paint and paint protection layers help shield the materials behind it from corrosion, rust or other damage. Ensuring the coating goes on accurately and repeatably without clogging is a must for truck and auto manufacturers. Preventing clogs and providing steady spraying keeps the line moving while ensuring the most uniform results.

In this application FQB2 mass flow controllers are piloting PSR volume boosters to control air pressure of a paint spraying robot. One assembly is controlling the shape of the plume and the other unit is controlling the atomization of the paint. The FQB2 units rapidly track requested flow rates, allowing for immediate corrections and on-the-fly changes to the spray pattern profiles. Upstream of these units are BVR manual pressure regulators to control the inlet pressure. The third unit, an ISQBX, is controlling the amount of paint going to the spray gun by piloting a fluid regulator. All of the units are mounted in an enclosure away from the paint booth in this automated paint spraying example.
