METHODS AND DEVICES FOR JETTING VISCOUS MEDIUM ON WORKPIECE

摘要

In a method for jetting droplets of viscous medium on a workpiece, a jetting machine iteratively jets the droplets of viscous medium from a jetting nozzle onto a first surface of the workpiece to form a single continuous mass of material at an edge of the first surface of the workpiece. At least a portion of the single continuous mass of material extends past the edge of the first surface and adheres to a second surface of the workpiece.

1. A method for jetting droplets of a viscous medium on a workpiece using ejector-based non-contact jetting technology, the method comprising:
iteratively jetting droplets of the viscous medium from at least one jetting nozzle onto a first surface of the workpiece to form a single continuous mass of material at an edge of the first surface of the workpiece; wherein
the iterative jetting of droplets of the viscous medium onto the first surface is performed while the at least one jetting nozzle is in motion without stopping at each location on the workpiece where viscous medium is to be deposited, andat least a portion of the single continuous mass of material is carried past the edge of the first surface of the workpiece.
