Patent ID: 8334023

Claim:
A method for calibrating a dispensing system having a position detector with a detection point and an applicator with an application point downstream from the detection point, the method comprising: specifying a target start position on a workpiece for receiving an amount of a material transporting a first plurality of the workpieces and a second plurality of the workpieces in a direction intersecting the detection point and the application point; as the first plurality of the workpieces are transported past the application point, dispensing the amount of the material onto each of the first plurality of workpieces with a first operating parameter of the dispensing system set at a first value; as the second plurality of the workpieces are transported past the application point, dispensing the amount of the material onto each of the second plurality of workpieces with the first operating parameter of the dispensing system set at a second value; detecting an actual start position of the amount of the material on each of the first plurality of the workpieces and on each of the second plurality of the workpieces; comparing the actual start position for the amount of material on each of the first plurality of the workpieces and each of the second plurality of the workpieces with the target start position for the amount of material to yield a plurality of start errors correlated with the first parameter; and deriving a mathematical relationship from the plurality of start errors correlated with the first parameter, the first value of the first operating parameter, and the second value of the first operating parameter describing a start response compensation time for the dispensing system as a function of the first operating parameter of the dispensing system.
