A painting robot, also known as a spray painting robot, is an industrial robot capable of automatically spraying paint or other coatings. It was invented in 1969 by the Norwegian company Trallfa, which later merged into the ABB Group. A painting robot mainly consists of the robot body, a computer, and a corresponding control system. Hydraulically driven painting robots also include a hydraulic power source, such as an oil pump, oil tank, and motor.
Most painting robots employ a 5- or 6-DOF articulated structure, giving their arms a large range of motion and the ability to perform complex trajectory movements. Their wrists typically have 2-3 degrees of freedom, allowing for flexible movement. More advanced painting robots utilize flexible wrists that can bend and rotate in all directions, mimicking the movements of a human wrist. This allows them to easily insert themselves into workpieces through small openings to spray their inner surfaces.
Main advantages of paint spraying robots:
First, it has good flexibility.
1. Large operating radius and good flexibility.
2. It can achieve spraying of both the inner and outer surfaces.
3. It can realize the mixed production of multiple vehicle types, such as the mixed production of sedan, station wagon and pickup truck bodies.
II. Improve coating quality and material utilization rate.
1. The contour spraying trajectory is precise, improving the uniformity of the coating and other appearance spraying quality.
2. Reduce the amount of over-spraying and cleaning solvent used to improve material utilization.
3. Easy to operate and maintain.
1. Offline programming is possible, greatly reducing on-site debugging time.
2. The plug-in structure and modular design enable quick installation and replacement of components, greatly reducing maintenance time.
3. All components are easily accessible for maintenance, facilitating upkeep.
IV. High equipment utilization rate.
1. The utilization rate of reciprocating automatic spraying machines is generally only 40%-60%, while the utilization rate of spraying robots can reach 90%-95%.
Painting robots are generally hydraulically driven and feature fast operation and good explosion-proof performance. Teaching can be achieved through manual instruction or point-to-point numerical display. Painting robots are widely used in automotive, instrumentation, electrical appliance, and enamelware manufacturing processes.
