Development of Automatic Copper Wire Locating System for HDD Manufacturing Process: Image Processing Part

Abstract:

This research presents the result of study and development of image processing program to monitor the copper wire placement process prior to the autonomous soldering process. The program has been developed using Visual Studio C++6.0 with Open CV, which is software that is on the command image processing. The experiment has 3 parameters to consider, focal length of camera, color of lighting and lighting control the pieces. The experiment shows the result that control ambient light improve the image processing output. Using focal length of 100 mm gives error of less using focal length of 130 mm. The light illuminated color affects the reflection, red-light gives low reflect, compare to white-light. The image processing using this setup can detect soldering point up to 98.5 % and 92.5 % of copper wire is detected. The setup using white-light cannot detect soldering coordinates, and able to detect copper wire only 42.5%. To control the ambient light, the focal length of 100 mm, and the red illuminating suited for the image processing system of the autonomous soldering and copper wire placement.
