Fluid dispensing gun monitoring apparatus for use in plastic industry measures delay between detection of transition signals that turn on gun for detection of dispensed fluid, based on transition and feedback signals

摘要

A diagnostic monitor (60) automatically measures delay between detection of transition signals that turn on the gun (22) for corresponding detection of edges (72,74) of fluid dispensed on substrate (28), based on transition signals and feedback signals output from a sensor (70). An Independent claim is included for fluid dispensing gun monitoring method.
