Abstract: A system and method for controlling a needle motion of a material applicator are disclosed. The system includes an actuator assembly that contains a piezoelectric device, where the actuator assembly is connected to a needle and translates the needle along a vertical direction, and a sensor assembly that includes an emitter for emitting light, where a portion of the actuator assembly occludes a portion of the light. The sensor assembly also includes a receiver for receiving a non-occluded portion of the light and a sensor holder that secures the emitter and the receiver. The system further includes a controller in electrical communication with the piezoelectric device, emitter, and receiver, where the controller adjusts operation of the actuator assembly based on feedback received from the receiver.

CPC classification number: B05C5/0225 , B05C5/0237 , B05C11/1028
Abstract: A valve module with floating member for use in a fluid applicator and a fluid applicator comprising said valve module are disclosed. The fluid applicator further includes a valve module that is configured to control a flow of fluid from the chamber to the cavity. The valve module includes an upper valve seat and a valve stem operatively coupled to the drive pin and extending from the chamber to the cavity. The valve module further includes a retaining tip attached to the valve stem and a floating member disposed in the cavity between the opening and the retaining tip such that the valve stem passes through the floating member and the floating member is movable along a longitudinal axis of the valve stem.
