  • Method and apparatus for detecting a liquid spray pattern
    Patent number: 7188781
    Abstract: During a liquid spray pattern detection procedure, the sensor (50, 52) is operable to detect the presence or absence of an edge of the dispensed liquid spray pattern. The nozzle (18) of the liquid dispensing system is moved to a predetermined position (A) relative to the sensor (50, 52) to determine the presence or absence of the spray pattern and is then moved to a second predetermined position (B) relative to the sensor (50, 52) to again determine the presence or absence of the spray pattern. Based on these determinations, the width of the spray pattern can be verified. This provides a quick means to verify that the width of the dispensed pattern is within certain tolerances.

  • Viscous material noncontact jetting system
    Publication number: 20050001869
    Abstract: A viscous material noncontact jetting system has a jetting dispenser mounted for relative motion with respect to a surface. A control is operable to cause the jetting dispenser to jet a viscous material droplet that is applied to the surface as a viscous material dot. A device, such as a camera or weigh scale, is connected to the control and provides a feedback signal representing a size-related physical characteristic of the dot applied to the surface. The size-related physical characteristics of subsequently applied dots is controlled by heating and cooling, or adjusting a piston stroke in the jetting dispenser, in response to the size-related physical characteristic feedback. Dispensed material volume control and velocity offset compensation are also provided.
