Coordinate Calibration and Automatic Punch Design of Flexible Printed Circuit
2012
This project is aimed to study and manufacture a novel autochecking and punch system of FPC, which is based on computer vision, image processing and automatic control technique. The system realizes the auto-punching process by a serial of workflow, including catching material, taking photos, punching, dropping material and home moving. Coordinate calibration is the core of automatic punch system which accurately calculates the motor pluses by pre-calibrating system hardware coefficient and error, properly selecting reference coordinate system, realtime calculating location of reference point and twice image skew correction based on radon transform. Experiments show it satisfies the required precision standard of system.
