Abstract: A dispensing system includes a dispensing unit assembly configured to dispense viscous material and a gantry coupled to the frame. The gantry is configured to support the dispensing unit assembly and to move the dispensing unit assembly in x-axis and y-axis directions. The dispensing unit assembly includes a support bracket secured to the gantry and a movable bracket rotatably coupled to the support bracket by a first strain wave gear system configured to enable the rotation of the movable bracket with respect to the support bracket about a first axis. The dispensing unit assembly further includes a dispensing unit rotatably coupled to the movable bracket by a second strain wave gear system configured to enable the rotation of the dispensing unit with respect to the movable bracket about a second axis generally perpendicular to the first axis.

Abstract: A dispensing apparatus includes a frame having a gantry configured to provide movement in the X axis and Y axis directions, and first and second dispensing units coupled to the gantry and configured to dispense material onto a substrate. The second dispensing unit is coupled to the gantry by an automatic adjustment mechanism. The dispensing apparatus further includes a controller configured to control the operation of the gantry, the first dispenser, the second dispenser, and the automatic adjustment mechanism. The automatic adjustment mechanism is configured to move the second dispenser in the X axis and Y axis directions to manipulate a spacing between the first dispensing unit and the second dispensing. Methods of dispensing material on the substrate are further disclosed.

Abstract: A dispenser, configured to dispense material on a substrate, includes a dispensing unit having a housing with a chamber, a piston disposed in the chamber and axially movable within the chamber, and a nozzle coupled to the housing. The nozzle has an orifice co-axial with the chamber of the housing. The dispenser further includes an actuator coupled to the dispensing unit and configured to drive the up- and down movement of the piston, and a compliant assembly coupled to the actuator and the piston. The compliant assembly is configured to permit limited relative travel between the actuator and the piston. A method of dispensing is further disclosed.

Abstract: A method is used to identify and compensate for errors created by changes in the relative positions of a deposition unit and a vision system of a dispenser. The method includes calibrating the vision system, dispensing a pattern of features over a working area, moving the vision system over a deposition location to locate a deposition, obtaining an image of the deposition, tagging data associated with the image, calculating a relative distance between the deposition unit and the vision system, storing correction data with spatial location in a file for later use, and using the stored data to make small corrections prior to dispensing additional material.
