    1515495 Colour television tubes INTERNATIONAL STANDARD ELECTRIC CORP 17 Feb 1977 [19 Feb 1976] 06688/77 Heading H1D The multi-gun assembly of a colour television tube is angularly aligned about its longitudinal axis with respect to the phosphor pattern on the screen of the tube by separately positioning the tube envelope and the gun, before assembly, in a sealing device with the gun assembly rotatable about its axis and provided with optically effective position marks, e.g. apertures 7 and 8 in the convergence pot 6, Fig. 1; illuminating the marks by one or more light sources 1; receiving light from the marks in one or more receivers 2; and evaluating the output of the receiver(s) to determine the rotation required for correct alignment. For the arrangement of Fig. 1, the gun assembly would be rotated to provide maximum output from receiver 2, which is the situation shown. Reflecting rather than transmitting optical, marks may be employed.

    one
    The invention relates to the production of cathode-ray tubes, in particular color picture tubes.
    Methods are known for adjusting a multipath spotlight in a cathode-ray tube during its welding. 1. The orientation and precise installation of a multi-gun electron-optical system is ensured by unambiguously fixing the leg of the system in the candle and the candle in the spindle of the brewing machine. However, the disadvantages of these methods include the lack of control alignment and the process of welding the tube.
    The closest technical solution to the invention is a method for adjusting a multipath projector, starting from a color kinescope, by aligning the reference alignment plane in the brewer, which is the plane of symmetry of positional markings, with its nominal position, including rotation spotlight relative to the longitudinal axis and control the position of the positional markings 2.
    In this method, when combining an electronic searchlight and a cathode ray tube in the brewing device, the projections of the torch cup electrodes touch the two mechanical calibers made in the form of movable rods. Calibres make it possible to constantly measure the distances between fixed points — the positional markings , and achieve its specified position by turning the searchlight within 0.5.
    The disadvantage of such a mechanical installation is low accuracy and danger of twisting or bending.
    15 spotlights in the process of alignment.
    The whole invention is to improve the accuracy of the alignment.
    This is achieved by positioning markings of the optical type, illuminating them with rays of light, determining the dependence of the intensity of the rays that interact with the markings on the angle of rotation of the searchlight,
    25 and establish the indicated angle of rotation in accordance with the aforementioned dependency.
    By additional features, markings can be made optically.
    30 transparent and reflective and oluchup
    with rays of light in a different range of light waves.
    FIG. 1 and 2 illustrate embodiments of the method using optically transparent markings; in fig. 3 and 4 are exemplary embodiments of the method in the case of reflective marcs.
    In the first case (see, figure 1), the beam of light 1, formed by a system containing a light source 2, a focusing lens 3 and a cutting diaphragm 4, passes through optically transparent markings 5 and 6, made in the form of holes in the side walls of the searchlight 7, and is focused by the optical system 8 on the light receiver 9. The light source preferably emits light in the infrared range, since this light is less sensitive to environmental influences than visible light, which can also be used. The searchlight 7 is rotated until it reaches a maximum of the radiation intensity at the receiver 9.
    Improving the accuracy of the adjustment can be achieved by determining the position corresponding to the maximum intensity, by performing an instrument differentiation of the dependence of the radiation intensity on the angle of rotation.
    It is useful to introduce a lower threshold level of intensity recorded by the receiver 9, according to which the cathode ray tube can be rejected at an early stage of production.
    Holes that play the role of optically transparent markings, it is advisable to perform in the accelerating (cup) electrode spotlight, because their influence on the optical properties of the spotlight in this case is the least
    A possible improvement of this method using transparent markings is illustrated in FIG. 2. In this case, two light beams 10 and 11 are directed at a small angle, such that part of the luminous flux of both beams passes through mark 6. When turning the searchlight 7 using receiver 9, two maxima of the intensity curve are recorded. The nominal position of the spotlight corresponds to the intermediate between the maxima.
    (Fig. 3 shows the alignment method when using reflective markings. Rays of light from sources 12 and 13 illuminate markings 5 and b located on diametrically opposite sides of the searchlight. Markings are performed in the form of multilayer coatings with reflectance falling from the center to the periphery. Markings can be applied to any spotlight electrodes.
    In this system, if the searchlight is twisted by an angle D. ot, relative to the nominal position, then the departure of the reflected light beam is 2 liters, which determines the increased sensitivity of the method. The nominal position corresponds to the maximum intensity at the receiver.
    As follows from Fig. 4, with the adjustment, the scattered light can be used, focused on the receivers 14 and 15 using systems 16 and 17. With a high degree of adjustment, the intensity maximum is reached simultaneously in both receivers.
    When implementing the method of any one of the variants, it is possible to encode the markings by, for example, arranging a number of several slots or marks indicating the amount of displacement.
    0 To reduce radiation detection errors, it is advisable to modulate the light rays used in intensity or frequency.
    The invention improves the accuracy of the adjustment and produces
    rejection of cathode-ray tubes at an early stage of production, excluding production costs for the implementation of subsequent operations ...
