    • 专利摘要:
    An electrode of the electron gun assembly has two accurately positioned alignment apertures therein, a line connecting the centers of the alignment apertures being transverse to the central longitudinal axis of the gun assembly. The alignment method includes holding the electron gun assembly relative to the cathode-ray tube envelope and directing a collimated light source toward the alignment apertures. Next, the position of the electron gun assembly is rotationally stepped about its central longitudinal axis while the light source is pulsed in coordination with the steps in position of the electron gun assembly. During the rotation, the number of light pulses passing through the alignment apertures are counted up. Thereafter, the stepping direction of the electron gun assembly is reversed and the number of light pulses passing through the alignment apertures are counted down. The reverse rotation of the electron gun assembly is stopped when the number of counted down light pulses are half of the maximum number of light pulses counted up.

    The invention relates to the field of vacuum-vacuum technology and can be used in the technology of producing electron-beam tubes (CRT) when centering a multi-beam gun in the neck of an ELT
    The purpose of the invention is to improve the accuracy due to the orientation of the gun in the neck of the tube using a beam of light from a funny source that is directed through the holes of the ring collimator: mounted on the gun, recording and counting the number of pulses passed through the collimator when rotation of the gun around the longitudinal axis of the tube.
    The drawing shows a diagram of the device for implementing the method.
    The device contains a supporting structure 1, mounted for rotation around a longitudinal axis and made with a lever 2, into the screw hole of which a screw 3 is inserted, made in the form of an engine shaft 4, controlled by two inputs. One of the control inputs of the engine 4 is connected to a pulse generator 5, which is electrically connected to a light source ™, made in the form of a laser 6, installed with the possibility of a beam of light 7, using a mirror 8 on the photodiode 9, connected to a converter 10 current to voltage that is connected to a meter connected to a second control input of the motor 4.
    The method is implemented as follows.
    A multipath gun 12 with an annular collimator 13 fixed on it, which is extra-wide with holes 14, is mounted on the supporting structure 1 and placed in the neck of a non-CRT coaxially. Laser is turned on 6 and the gun 12 is oriented so that beam 7 of light falls on the lateral surface of the ring collimator 13 Then turn on the impulse generator 5, the pulses of which start the engine 4, drive the supporting structure 1 into rotation together with the gun 12 mounted on it, and also modulate the light beam generated by the laser 6.
    The pulse frequency of the generator 5 is set constant and proportional to the angular velocity of the engine 4, while rotating the gun 12 using the photodiode 9, pre

    The detector 10 and the counter 11 register light pulses and count their number during the time when the beam 7 of the light passes through both apertures 14 of the ring collimator 13, which is reversed by rotation and again counts the pulses when the light 7 passes through the holes 14 the collimator 13, the Rotation is stopped when the number of pulses counted after reversing the rotation is half the number of pulses counted during the rotation of the gun 12 in the original direction and then fix the gun 7 at the CRT neck.
    The engine 4 can be used as a motor providing a constant angular speed of rotation, as well as a stepping wheel.
    The method makes it possible to improve the accuracy of mounting the mcap-seam gun in the neck of the tube and, consequently, improve the quality of CRT assembly.
