Introduction 1-3
1.7 Standard Equipment and Features
1.7.1 Automatic Pattern Recognition (Vision) System
The Vision System consists of a Dalsa-Coreco Genie M640 digital 640 x 480 pixel camera, light source,
and laptop computer. The software consists of Fluidmove for Windows and its pattern recognition engine.
The vision system serves three purposes:
•
It allows the operator to teach dispensing locations on the substrate. The operator views a live
image of the camera’s target and uses the graphical user interface to create the dispensing
sequence.
•
It automatically aligns the user generated dispensing sequence to the actual position of the
substrate during run operations. This is made possible by the advanced pattern recognition
system which compares expected and actual fiducial locations on the substrate. Corner finder
and bitmap model finders are supported as well as a pattern skip feature.
•
It is employed during the prompted setup routine to establish the vision-to-needle offsets and
service station locations.
The Dalsa-Coreco Genie M640 replaces the earlier analog cameras used with the ITI PCVision frame
grabber. It communicates bi-directionally to a host computer via Gigabit Ethernet. No frame grabber is
required. The camera is currently configured to run at 60 full frames per second which is twice as fast as
the analog PCVision cameras. A frame can be transferred in 16.67 milliseconds.
Diffuse, on-axis lighting (DOAL) provides for consistent substrate illumination with color temperature
and intensity controlled through the software interface. Substrate images taught during programming
(along with the lighting levels) are stored with the program, and are automatically retrieved when loading
the program.
1.7.2 Calibrated Process Jetting (CpJ™)
With this feature, volumetric repeatability can be maintained during long production runs to improve
process capability (Cpk) when dispensing fluids with one of Asymtek's DispenseJets. Dispense patterns
are programmed with a specified weight. CpJ periodically samples the dispense weight per shot, and then
computes the number of shots for each pattern. With this information, CpJ optimizes line speed based on
maximum specified shot interval.
1.7.3 Computer System
The Computer System consists of a laptop computer with an adjustable height bracket. It runs Fluidmove
for Windows XP (FmXP) software.
1.7.4 Conveyor
The Conveyor allows parts to be conveyed by a flat belt from upstream systems, to the dispensing station,
and then to downstream systems. The system is available with either a single lane or dual lane conveyor
configuration. All conveyors are SMEMA compatible and have adjustable rear rail width. The conveyor
system uses multi-move technology which allows parts to move concurrently. This aids throughput by
minimizing conveyor time. Previous technology only allowed one part to move at a time.
1.7.4.1 Single Lane
The Single Lane Conveyor provides continuous part processing.
