The article suggests several methods to reduce process variation in automated gasket dispensing. It notes that standoffs usually used for dispensing dots of materials can also be adopted in controlling the dispense height because they have less cycle time. It recommends ultrasonics, third-dimensional (3D) stereoscopic vision, laser triangulation and tactile sensors in automatic height measurement. The article advises combining tip calibration and height measurement systems to close the control loop in dispensing.
