Fig. 6. Camera location
The result of calling COM modules can be seen clearly in the figure 5. The average
vertical ordinate of simulated PCB images is 11. Therefore, real positions can be
calculated by certain proportions. In my research, positions can be obtained through
PCB board simulating method under an ideal environment. Because PCB boards are
fixed on X-Y workbenches in real dispensing environments, PCB boards will move
when X-Y workbenches move and CCD cameras are fixed in installations, as shown
in figure 6. Hence, real positions can be obtained.
In position-settings, buttons of the upper computer is operated and X-Y workbench
moves to the position set. At the same time, the camera is opened and the current
position is captured. Finally, image processing button is pushed. Therefore, it can be
told whether the position of the dispensing is at the center of the image. If the position
is out of areas allowed, the position should be adjusted to its presets in order to ensure
the accuracy of the dispensing.
5 Conclusion
The image process software designed has been used successfully in multi-axis kinetic
control systems, through which the automatic level of dispensing systems has been
improved greatly. The software can also be used in similar kinetic control systems
with certain market value.
