Abstract
A dispensing system for jetting a material onto a substrate is disclosed. The dispensing system includes a plate defining a first surface, a second surface opposite the first surface in a first direction, and at least one slot that extends through the plate from the first surface to the second surface, and an actuator assembly that contains a piezoelectric element and is operatively coupled to the needle. The dispensing system also includes at least one fastener that extends through the actuator assembly and the at least one slot, where the at least one fastener is configured to selectively engage the plate such that 1) in a disengaged configuration, the at least one fastener is movable within the slot and the actuator assembly is movable relative to the plate, and 2) in an engaged configuration, the at least one fastener is not movable within the slot and the actuator assembly is not movable relative to the plate such that a stroke length of the needle is adjusted.
