Abstract: This invention relates generally to systems for depositing a material onto a surface, and more particularly, to control systems for metering the amount of material being dispensed. The present invention provides an active compensation metering system that automatically compensates for material changes due to changes in material pressure, material temperature, and material viscosity.
Abstract: A compact spray valve that provides an extended atomizing air cap for reaching between tightly spaced electronic components. The compact spray valve of the present invention includes an air body, a fluid control body and an extended atomizing air cap. The atomizing air cap along with a seat extension provides a plurality of laminar air flow conduits causing atomization of a fluid into a spray. The resulting spray pattern can be controlled to provide a narrow line spray pattern with clearly defined edges. Another embodiment of the present invention provides a flat spray pattern.

Abstract: A robotic conformal coating system has a end effector and multiple tiltable valves coupled to the end effector. The end effector is capable of X, Y and Z axis motion, as well as rotation about the Z axis. A programmable controller controls the movement of the end effector and valves, as well as the actual dispensing and/or spraying of conformal coating.

Abstract: A valve is provided including a body made of anaerobic, reactive fluid resistant material. The valve also directs pressurized fluid in a substantially planar manner between adjacent port holes on a recessed area of a fluid body section of the valve. The flexible diaphragm can be actuated manually or programmed to dispense pressurized fluid, such as cyanoacrylate fluid. A method of dispensing anaerobic, reactive material is also provided.
