The automated application of paint, gelcoat, fiberglass and other coatings has evolved significantly over the decades. This transformation has been driven by the need to guarantee consistent application, minimize health risks to workers and optimize overall process efficiency.
In this article, we'll explore the technical aspects of robotizing this application, the types of robots available, the benefits of using them, and finally, the crucial importance of working with a robot integrator.
The introduction of robots for coatings began in the 1980s, with General Motors pioneering the use of robots in its automotive plants. Since then, robotics giants such as ABB, Fanuc, Yaskawa and Kuka have developed specialized coating robots. This evolution has transformed the way various industrial sectors approach the finishing of their products.
Different types of robot can be used, depending on the complexity of the geometry of the objects to be coated. Linear" robots are ideal for flat surfaces, while "serial painting" robots offer increased flexibility with their ability to apply coatings at various angles. The integration of several robots, the use of linear axes, and conveyors can be effective strategies for handling large parts.
Repeatability is the key advantage of using robots. Their ability to follow precise trajectories at a constant speed guarantees uniform application, respecting minimum coating thickness tolerances. What's more, the use of robots reduces the risks to human health when handling potentially harmful coatings, while ensuring compliance with safety standards.
Automation reduces the level of risk to workers, but it's crucial that paint chambers comply with explosion-proof standards where necessary. Safety remains a priority even in a fully robotized environment.
The key to success in paint robotization lies in working with an experienced integrator. These experts will guide the selection of the right robot for your specific production needs, and facilitate its smooth integration into your existing processes.
Our main observation is the substantial benefits achieved in terms of raw material savings. This automated process, carried out by the robot, guarantees the precise application of the pre-defined quantity of raw material. Compared with a human operator, whose variations in the quantity applied can be significant, automation offers unrivalled precision.
This precision translates into substantial savings, particularly when applying large volumes. The robot's rigorous control of the amount of material applied makes a significant contribution to cost optimization and, consequently, to a remarkably rapid return on investment.
Automated coating application offers significant advantages in terms of quality, efficiency and safety. By choosing the right type of robot and working with specialist integrators, companies can improve productivity and stay at the cutting edge of technology in a constantly changing industrial world.
