With the continuous development of the electronic manufacturing industry, as well as electronic continuously shortening product development cycle, based on physical fast PCB engraving machine by numerous electronic laboratory, research institutes, such as research and development department. Based on the circuit board processing physical engraving, different from the traditional chemical etching plate method. Physical method is carving processing circuit board line information can be converted to track the location of the coordinate information, and then by controlling the engraving cutter guide moving along the x, y axis, remove copper clad in spare part line processing. When high speed engraving and milling machine processing and double panel, the underlying processing after the completion of the circuit board along the axis of the two pins to flip will be the top image processing data along the axis at the same time, to the top processing. If flip axis axis and the data is not completely overlap, or offset along the axis direction makes the solder hole center and bonding pad don't overlap, producing machining defects, as shown in the figure below. In order to eliminate positioning, need to detect the position deviation after turning to adjust processing data. The traditional positioning method has been difficult to meet the system position accuracy requirement, and computer vision technology with its unique advantages better solve PCB flap positioning in the process of machining process problems.
