Abstract
In order to study how to improve splicing precision between galvanometer processing grids cut by dynamic-optic-type laser,a seamless splicing method for grids was introduced.Firstly,the area coefficients of laser points for both axes were compensated with linear interpolation.Then projective transformation was applied to establish the projective transformation matrixes of points in two optional planes to compensate trapezium and diamond distortion of dual galvanometers.After the above compensation,all coordinates in the entire scanning filed accord with a certain linear proportion relationship.Applying this method to cut flexible printed circuit board,experimental results showed that cutting precision and efficiency of this system were much higher than ordinary static-optic-type cutting.The splicing precision between grids of laser cutting system is greatly improved up to the precision and efficiency of the latest foreign system of the same kind.关键词
