The Flashlamp
Subsystem consists of the high-energy pulsed power supply, de-ionized
water-cooling system, cooling water lines, and high-energy power cable.
During FLASHJET Coatings Removal System operation the high-energy pulsed
power supply converts input voltage to high-energy output voltage, which is
delivered to the Stripping Head Subsystem. The Flashlamp in the Stripping
Head Subsystem provides the pulsed-light energy necessary for ablation of
the surface coating. Flashlamp Module cooling is provided by the de-ionized
water-cooling system. The Flashlamp Subsystem Block Diagram is shown at
right. |

The CO2 Pellet Subsystem
consists of the liquid CO2 storage vessel, Pelletizer and Blast Units, air
compressor/aftercooler, air dryer, oil/water separator, receiver and hoses
for delivery of clean high-pressure blast air and dry ice particles to the
nozzle assembly. During FLASHJET Coatings Removal Process operation, the
dry ice particle stream sweeps away the soot residue resulting from ablation
of the coating, provides substrate cooling, and provides a CO2
rich atmosphere, which prevents combustion within the effluent
capture shroud. The CO2 Pellet Subsystem Block Diagram is shown at right.
The Process Controller controls the main functions of the CO2 Pellet
Subsystem in FLASHJET Coatings Removal Process operation. |

The Effluent Capture
System (ECS) is a high volume, high velocity vacuum system. The ECS Block
Diagram is shown at right. The ECS consists of a motor and fan vacuum
source that is connected to a combination of traveling aperture (zipper
ducts), rigid ducting, flexible ducting, and the Stripping Head Assembly ECS
duct and shroud. The ECS collects the effluent that results from the
stripping process. The effluent is routed through the ECS large particle
collector, blower section (motor/fan), pre-filters, HEPA filters, and the
activated charcoal “tub scrub”. These filtration stages collect virtually
all particulate matter and neutralize gaseous compounds so that the output
of the tub scrub is extremely clean and proven environmentally safe. |

(The following is a
description of the WR-ALC Gantry Robot.
Robots may have unique characteristics, based on their intended use.)
The Gantry Robot Subsystem controls all movement of the Stripping Head
Subsystem. The Gantry Robot Subsystem is comprised of a Gantry Assembly
that provides "X," "Y," and "Z” directional travel, a “Z” mast arm which
allows extended reach of 8 feet rotationally about the “Z” axis, a Wrist
Assembly that provides yaw, pitch, and roll orientations, and a Robot
Controller Assembly. The stripping head is physically mounted to the Wrist
Assembly. All FLASHJET Process umbilicals are routed like the gantry robot
umbilicals in articulated cable carriers (cat track). The Gantry Robot
Subsystem block diagram is shown at right.

The Process Control
Subsystem hardware/software is responsible for controlling all the FLASHJET
Process Subsystems, such as the CO2
Pellet, Flashlamp, Stripping Head, Effluent Capture, and Mobile
Manipulator. It is the User Interface to control the FLASHJET Coatings
Removal Process. The Process Control Subsystem Block Diagram is shown at
top
right. The Process Control Subsystem consists of a Process Controller
Assembly and a Remote Operator Station (ROS).

The Stripping Head
Subsystem, referred to also as the “end-effector”, consists of the major
working components of the FLASHJET Coatings Removal System. This assembly
is mounted to the mobile manipulator wrist assembly, and consists of the dry
ice particle stream nozzle assembly, color sensor assembly, flashlamp
module, effluent capture duct and shroud, collision sensors, standoff
distance sensors, and zone feature lasers. The Stripping Head Subsystem
Block Diagram is shown at top right.
A typical Stripping Head Assembly is
