International Classification:

F25B 21/02

US Classification:

62 34, 62 364

Abstract:

Apparatus and methods for dispensing small amounts of a viscous material onto a workpiece. The narrow-profile dispensing apparatus includes a fluid chamber, a nozzle, and a valve seat disk representing individual components that are removable from a main body of the dispensing apparatus for cleaning and/or replacement. The nozzle is coupled with the fluid chamber by a heat transfer body that may be cooled by, for example, a cooling fluid routed through an air pathway defined in the heat transfer body. The main body of the dispensing apparatus may be cooled by air exhausted from an air cavity of a pneumatic actuator regulating the movement of a needle to control the flow of viscous material in the dispensing apparatus.

US Classification:

4274211, 13762413, 137 1, 118696

Abstract:

An improved pneumatic jetting valve includes a housing with first and second chambers. A pneumatic piston is enclosed between the chambers. First and second solenoid valves are configured to respectively supply air pressure to the chambers and to exhaust the chambers. A controller is operable to regulate the pressurization and venting of the chambers. The controller controls the timing of control signals for the first and second solenoid valves to control the overlap time during which both the first and second chambers are pressurized. By controlling this overlap time, the controller controls the speed of the drive pin of the jetting valve and thereby the speed at which the valve closes to jet a droplet of material. This allows a valve speed to be selected that is most appropriate for the viscosity of the material being jetted. Numerous new methods for utilizing the improved jetting valve and system are disclosed.

International Classification:

B05C 500

B05B 1500
B05B 102

US Classification:

118663

Abstract:

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.

International Classification:

B05C 1100
B05C 500

US Classification:

118668

Abstract:

A syringe or other suitable dispensing device is coupled to conventional controls for dispensing viscous material such as adhesives or solder paste through a tip thereof. The syringe is supported on a motor driven carriage for movement along a Z axis in response to height control signals. A camera also mounted on the carriage generates output signals representative of an image of the surface of a workpiece such as a PC board. Circuity processes the output signals from the camera to determine when the image is maximally in focus and generates the height control signals necessary to maintain the tip of the syringe a predetermined constant height above the surface of PC board. This ensures the dispensing of uniform balls of solder paste or adhesive at various locations on the PC board despite warpage in the board.

International Classification:

B05D 512
B05C 500

US Classification:

427 96

Abstract:

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.

International Classification:

B05C 1100

US Classification:

427 8

Abstract:

A method is provided for dispensing viscous materials which first requires the step of providing a dispensing device for holding a quantity of a viscous material to be dispensed through a tip thereof. Next, the dispensing device is coupled to a dispensing control so that a metered amount of viscous material will be dispensed in response to a dispensing control signal. Next, the dispensing device is moved along an axis to selectively position the tip a predetermined distance away from the surface of a workpiece positioned adjacent thereto in response to an applied height control signal. The height control signal is generated by processing output signals from a camera which is moved along the axis with the dispensing device to determine when an image of the workpiece surface is maximally in focus. The final step of the method is to cause the dispensing control to apply the dispensing control signal to cause a metered amount of the viscous material to be dispensed from the tip of the dispensing device onto the workpiece surface.

International Classification:

B05C 502

US Classification:

222 1

Abstract:

A syringe or any other dispensing device is coupled to a conventional dispensing control unit for dispensing viscous material such as adhesives and solder paste through a hollow needle thereof as metered amounts of pressurized gas are supplied to the syringe in response to a valve control signal applied to the dispensing control unit. The syringe is mounted on an automated frame for independent movement along the X, Y and Z axes in response to drive signals. Predetermined pattern and fluid flow functions are selected for each of a plurality of consecutive movement elements by operator actuation of corresponding discrete manually actuable switches to thereby create a workpiece program which can be automatically executed on command to dispense the viscous material over the upper surface of a workpiece such as a PC board in the prescribed manner.

Abstract:

Methods of dispensing fluid are disclosed. A first applicator is positioned above a first dispense site at a first dispense region of a first electronic substrate by moving the first applicator using a primary positioner. A second applicator is simultaneously positioned above a first dispense site at a second dispense region of the first electronic substrate by moving the second applicator together with the first applicator using the primary positioner and moving the second applicator relative to the first applicator using a secondary positioner. It is then determined that the first or the second dispense region is misaligned relative to the other of the first or the second dispense region. Fluid is dispensed from the first applicator while moving the first applicator using the primary positioner to form a first fluid pattern at the first dispense region and fluid is simultaneously dispensed from the second applicator while moving the second applicator using the primary positioner and the secondary positioner.
