检查系统,用于和方法,用于检查印刷在工件上的沉淀通过印花网板,系统包括:照相机单元活动的相对印花网板,其中,包括主体,包括多个孔,以及工件上,其沉积物透印孔印花网板; 以及控制单元用于控制相机单元例如捕获图片至少一对对应区域印花网板以及工件,以及处理这些图片确定,用于每一个多个点定义图片的印花网板,是否点孔,以及,仅,其中尖头孔,判断对应点对应图片工件,如由多个对应点, 是沉积物,从而确定打印特性沉积物打印在工件从关系点确定沉积确定的点被孔。
Inspection system for and method of inspecting deposits printed on workpieces
An inspection system for and method of inspecting deposits printed on workpieces through a printing screen, the system comprising: a camera unit movable relative to a printing screen, where comprising a body including a plurality of apertures, and a workpiece on which deposits are printed through the apertures of the printing screen; and a control unit operable to control the camera unit such as to capture images of at least one pair of corresponding regions of the printing screen and the workpiece, and process the images to determine, for each of a plurality of points defining the image of the printing screen, whether the point is of aperture, and, only where the point is of aperture, determine whether the corresponding point of the corresponding image of the workpiece, as defined by a corresponding plurality of points, is of deposit, thereby enabling a determination of a print characteristic of deposits printed on the workpiece from a relationship of the points determined to be of deposit to the points determined to be of aperture.
