Robot Blasting System

Guyson Corporation has integrated a six-axis robot nozzle manipulator into an automated rotary blast machine for repetitive surface treatment operations. The blast system was developed to consistently perform critical surface preparation on irregularly shaped components, but also suitable for a variety of other blasting applications. The articulated robot arm is rigidly mounted at the rear of the blast cabinet on a welded base attracted to the frame of the finishing enclosure.

Guyson Corporation has integrated a six-axis robot nozzle manipulator into an automated rotary blast machine for repetitive surface treatment operations. The blast system was developed to consistently perform critical surface preparation on irregularly shaped components, but also suitable for a variety of other blasting applications.

The articulated robot arm is rigidly mounted at the rear of the blast cabinet on a welded base attracted to the frame of the finishing enclosure. Fitted tightly around the effector end of the robot that extends into the blast chamber through an opening in the back wall of the cabinet is a custom-tailored Hypalon-laminated nylon skirt to seal the rear of the blast machine and isolate the precision manipulator form the abrasive blasting environment. Workers are excluded from the area around the robot by a welded wire cage.

In addition to the motion capabilities of the robot, the rotary table of the blast machine is driven by a servomotor that is integrated with the robot controller as a seventh axis of motion. The radial orientation of a component fixtured on the table can be programmed with accuracy and synchronized with complex motions of the blast nozzle, allowing precise control of the distance and speed of the nozzle(s) in relation to the surface of the component.
