ABSTRACT:
A method and apparatus for measuring and controlling the size of drops of viscous material dispensed from a dispensing system. A dispensing apparatus in accordance with embodiments of the present invention includes a housing, a dispenser that dispenses a quantity of the viscous material, a measuring apparatus having a bottom plate to receive the viscous material, a top plate that is positioned over the bottom plate after the viscous material has been dispensed, and a compressing apparatus that compresses the material between the top and bottom plates. The dispensing apparatus further includes a viewing system that views the compressed material to determine the quantity of material dispensed by the dispenser. In one embodiment, the dispensing apparatus includes a controller that controls the quantity of viscous material dispensed based on the quantity of material determined by the viewing system.
