Professional, Scientific, and Technical Services/541330 -- Engineering Services

Specifications List for Atmospheric Pressure Plasma Robot (APPR)   Description:  A system that generates a plasma jet at approximately atmospheric pressure (or greater).   The system shall include a Cartesian robot (three dimensional) that allows dispensation of the plasma on  a surface (2D or 3D). The Cartesian robot shall accommodate components of at least 12’’ x 12’’ x 4’’ in  length x width x height. The robot must interface with a computer (can be supplied by APPR vendor or  other source) to program the path and speed of plasma dispensing.  The power, gas flow rate, frequency  of electrical arc, and type of gas used shall be adjustable.   Detailed Specifications of APPR system:  ? Plasma Power: 700 to 1100 W o Frequency Range: 200 kHz to 80 kHz ? Compatible carrier gases: Air, Nitrogen ? Flow rates: 30 to 70 l/min (Typical value is 40 l/min) ? Gas pressure 2.5 to 6 bars ? Plasma jet effective processing area: 5 to 20 mm ? Maximum temperature of plasma: 200 °C ? Optional capabilities: o Carrier gas can be doped with two other gases (i.e. oxygen, hydrocarbons, hydrogen, etc.) o One dopant gas line supplied with system o 2nd dopant gas line can be added
? Cartesian Robot o 3 axis: length > 300 mm, width > 300 mm, height = 100 mm o Speed up to 300 mm/s o Position repeatability: <1 mm o Programmable software for motion control ? Programmed with touchscreen interface with optional mouse/monitor interface o Stores multiple programs o System includes a frame and protective enclosure around robot system.
? Spare parts to be included with system: ceramic insulators and electrodes ? Power requirements for both robot and plasma generator (APPR system): 110 to 220 VAC, 5060Hz
