Abstract:
The invention provides an apparatus and method for dispensing material onto a substrate. The apparatus comprises a dispensing system having a dipenser and a control system adapted to adjust a quantity of material to be dispensed onto the substrate. It also includes an image capturing system adapted to acquire an image of the material that is dispensed onto the substrate, a measuring system to analyze the image and measure the quantity of material dispensed, and a compensation system adapted to provide a correction signal to the control system to vary the quantity of material dispensed.
Abstract:
The invention provides an apparatus and method for calibrating a dispensing system. A dispenser dispenses a controlled quantity of material into a container for receiving material. A system, preferably a vision system comprising an image capturing device and an imaging system, is adapted to capture an image of a physical dimension of a quantity of dispensed material in a given time. The physical dimension may be a width of a top surface area, a height or a cross-sectional area of the dispensed material. A calibrating system is adapted to calculate a volume of the quantity of material based upon said physical dimension.
