摘要： This invention concerns a method and apparatus for dispensing minute quantities of highly viscous material from a jetting needle when an expelling mechanism is activated using a nozzle plate with a jetting chamber having a top formed by a diaphragm and a bottom in fluid communication with a jetting needle. Fluid enters the chamber from an inlet channel and is jetted from the chamber by deforming the diaphragm to block the channel and expel a drop of fluid from the needle. A diaphragm driven metering chamber and/or reservoir chamber can optionally be used provide fluid to the jetting chamber.

摘要： This invention concerns a method and apparatus for dispensing minute quantities of fluids and more particularly rapidly dispensing highly precise and repeatable, minute amounts of viscous fluids in a non-contact manner. An impacting element is impacted against a hardened insert on a flexible diaphragm to deflect the insert into a jetting chamber and against an outlet orifice in the jetting chamber. The movement of the diaphragm and insert force viscous fluid in the chamber through the outlet orifice and the impact jets that fluid from the outlet orifice, with the impact force being adjusted to jet the fluid from the orifice in a single drop.

摘要： A computer controlled system for high speed surface mount adhesive placement in circuit board production includes a dot generator supported for motion along the X, Y and Z axes. The dot generator ejects a jet of viscous adhesive that breaks away from the nozzle of the dot generator as a result of its own forward momentum. The system includes an automatic circuit board conveyor with adjustable width and pneumatically operated lift and lock mechanisms. The system runs through a self-diagnostic set-up procedure and dot calibration routine. Dot size and location are monitored through a video camera and vision circuit. A computer interfaces with the vision circuit and with motion, dot generator and conveyor controllers so that the system can operate in a high volume production assembly line. Application programs are executed by the system computer typically utilizing CAD data from a disk or a computer integrated manufacturing (CIM) controller. The system automatically assigns dot sizes to specific components based on user specifications or a component library. Dot placement paths are optimized by aligning the in-line points.

摘要： A computer controlled method for high speed viscous fluid dispensing includes the steps of providing a dot generator and moving the dot generator along at least X and Y axes. The dot generator is controlled to repeatedly eject jets of viscous fluid that break away from the dot generator as a result of their forward momentum and fly to the surface of an adjacent substrate to create dots. The method may further comprise the step of monitoring the size and location of the dots through a vision system. The method may further comprise the steps of assigning dot sizes to specific components based on user specifications or a component library. The method may further comprise the step of optimizing the dot placement paths by aligning the in-line points of dot formation.

摘要： A chamber that communicates with a viscous material reservoir has a flexible resilient diaphragm which forms an exterior wall thereof. An impact mechanism, which may comprise a solenoid actuated hammer, applies a predetermined momentum to the diaphragm for rapidly metering a predetermined minute blob of the viscous material from the chamber through a nozzle. The reservoir is pressurized with gas to force the viscous material into the chamber to refill the same. The chamber is heated to control the viscosity of the material. Dispensing rates in excess of four blobs per second can be achieved. Variations in the height of the nozzle from the surface of the workpiece are not critical to uniform rapid dispensing. An alternate embodiment eliminates the diaphragm and instead rapidly retracts a nozzle relative to a fluid feed conduit to eject very small blobs of viscous material. A strain gauge detects refill of the chamber inside the nozzle and sends a signal to control refill logic circuitry. A fiber optic droplet detector is utilized to correct dispensing defects.

摘要： A disposable nozzle assembly for connection to the lower end of a syringe in a viscous material dispensing apparatus. The disposable nozzle assembly includes a nozzle portion having an internal cylindrical drop generation chamber and an exit orifice. A cylindrical feed tube having a central feed passage has a lower end that can slide up and down within the cylindrical drop generation chamber. A dynamic seal is provided on the lower end of the feed tube that prevents viscous material from escaping between the feed tube and the inner wall of the drop generation chamber. The disposable nozzle assembly is further provided with a modified luerlock fitting having an internal hollow stem that mates with the tapered nozzle of a standard adhesive syringe in a manner which prevents the entrapment of an air bubble in the fluid path when an empty syringe is replaced.
