Abstract
A robotic wash cell is provided and includes a six-axis robotic arm and end effector equipped with nozzles that spray unheated, solvent free, pure water at high-pressure to clean or debur objects by maintaining the nozzles in close proximity and substantially normal to each surface being cleaned or edge being deburred. The robotic cell wash is particularly useful for cleaning contaminants such as oil and grease from items having more complex shapes. The six-axis robotic arm positions the nozzles and their sprays substantially normal to each surface being cleaned or deburred. The nozzles produce a multi-zone spray pattern with a continuous effective cleaning zone. A water recycling and pressurizing system collects the used water, separates out the oil and grease contaminants to a level of about 5 ppm, and pressurizes the pure water to about 3,000 psi for washing operations or about 6,000 psi for deburring operations.
