Motoman Robots Painting

Two Motoman PX2850 robots use the same spray equipment to apply zinc primer and epoxy topcoat paint onto large, complex weldments fixtured on a headstock/tailstock positioner that uses an adjustable slide to accommodate part length variations.Heavy Equipment Weldments

Robot system meets or exceeds project objectives, significantly improving productivity and eliminating a production bottleneck. Flexible robot painting system accommodates variety of part sizes which are loaded/unloaded using a forklift truck. Robots paint parts 50%-60% faster than manual methods, and use same spray equipment for two-component zinc primer and epoxy top coat. Robotic spraying improves consistency of coating thickness and finish compared to manual process and significantly reduces paint usage and overspray, resulting in cleaner, safer environment.

Fixtures/Tooling Details

Motoman Robotics provided custom fixtures and associated tooling to deliver a flexible solution within a painting environment for one family of parts, including any inconsistencies/warping in the complex weldment. Fixtures are designed to allow loading/unloading using a forklift truck. Clamshell-type headstock tooling with manual latches provides positive, repeatable part loading/unloading and can hold the maximum load while the part is rotated upside down. No sensors are used.
