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 system for dispensing a viscous material onto a substrate which includes a dispensing element, a viscous material reservoir and a metering device coupled between the reservoir and the dispensing element for metering a variable amount of a viscous material through the dispensing element. The dispensing element and metering device can be moved by a positioner along a predetermined pattern adjacent a surface of a substrate. A weigh scale located adjacent the substrate receives a metered amount of the viscous material and produces signals representative of a variable weight of the material dispensed during a predetermined time interval. A controller adjusts a speed of movement of the positioner along the predetermined pattern to cause the dispensing element to dispense a desired amount of material based on a calculated flow rate. Alternatively, the controller adjusts a rate of delivery of the metering device based on the calculated flow rate to cause the dispensing element to dispense the desired amount of material along the predetermined pattern. Closed loop temperature control may be provided for the dispensing element and/or the substrate to ensure a substantially constant viscosity and a substantially constant flow rate. A prime and purge station may be provided adjacent the substrate for sucking air bubbles from the dispensing element and metering device.

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.

摘要： A quilting machine includes a frame sized and configured to support a sheet of fabric and a tilting sewing assembly. The tilting sewing assembly includes a needle beam defining a needle beam longitudinal axis, and a needle head attached to the needle that translates along the needle beam longitudinal axis. The assembly includes a hook beam defining a hook beam longitudinal axis disposed separate from and parallel to the needle beam longitudinal axis, and an axis of rotation parallel to the needle beam and the hook beam with the hook beam disposed between the needle beam and the hook beam. The needle head is between the needle beam and the hook beam. The tilting sewing assembly is configured to pivot about the axis of rotation with the needle beam and the hook beam translating laterally about the axis of rotation to move the needle head relative to the frame.
