    • The invention is concerned with the problem of providing an automatic inspection device, with which it is possible to determine, with little effort and without contact, whether packages, particularly sealed blister packages consisting of a blister container and a cover film, are free of defects. This problem is solved by the use of at least two light sources, which are arranged at a certain distance from one another and each emit a light bundle at a predetermined wavelength range, whereby the emission maxima of the two light sources are offset in relation to one another. The light sources are arranged such that the packages are vertically illuminated. The light reflected by the packages is recorded by a CCD camera and the digital images are stored in a computer, so that they are available in a computer-supported image-processing and documentation system.
    • 本发明涉及提供自动检查装置的问题,通过该检查装置可以很小的努力并且不接触地确定由泡罩容器和覆盖膜组成的包装,特别是密封的泡罩包装是否没有缺陷 。 通过使用至少两个光源来解决这个问题,这两个光源彼此间隔一定距离,并且每个光源以预定的波长范围发射光束,由此两个光源的发射最大值相对于 另一个。 光源被布置成使得包装件被垂直照明。 由CCD照相机记录由包装盒反射的光线,并将数字图像存储在计算机中,以便在计算机支持的图像处理和文档系统中可用。
