Embodiment 1
[0030] With reference to Fig. 4 according to the processing method of adjusting color picture tube electron beam arrangement of the present invention:
[0031] 1) Adjust the converging state of the blue, green and red beams in the center of the fluorescent screen with the color-purity converging magnetic piece installed on the tube neck to make it meet the general manufacturing standards;
[0032] 2) Adjust the magnetic field of the deflection yoke (1) so that the converging states of the blue, green and red beams on the entire screen meet the general manufacturing standards;
[0033] 3), adjust the front and rear positions of the color pure converging magnetic part and the deflection coil (1) on the tube neck, and observe the landing state of the screen reference point with a microscope, so that the landing state of the green electron beam meets the general manufacturing standard;
[0034] 4), use a microscope to observe the blue, green and red three electron beam landing sta...
Embodiment 2
[0038] With reference to Fig. 5 according to the technological method of adjusting color picture tube electron beam arrangement of the present invention:
[0039] Steps 1)-3) are the same as steps 1)-3) of Example 1.
[0040] 4), use a microscope to observe the blue, green and red three electron beam landing states on the periphery of the fluorescent screen. If it is consistent with the state shown in Figure 5, according to Figure 3, the belt (2) can be tightened on the deflection coil (1). ) on the left and right sides, 16mm to 26mm away from the center of the pipe neck, each attaches a magnetic block (3) with a magnetic flux of 0.96mT, the S pole of the left magnetic block is upward, and the S pole of the right magnetic block is downward;
[0041] 5). Use the color-purity converging magnetic piece installed on the tube neck to readjust the converging state of the blue, green and red beams in the center of the screen to make it meet the general manufacturing standards;

Embodiment 3
[0044] With reference to Fig. 6 according to the technological method of adjusting color picture tube electron beam arrangement of the present invention:
[0045] Steps 1)-3) are the same as the steps 1)-3) of Embodiment 1 and 2) process.
[0046] 4), use a microscope to observe the blue, green and red three electron beam landing states on the periphery of the fluorescent screen. If it is consistent with the state shown in Figure 6, as shown in Figure 3, the belt (2) can be tightened on the deflection yoke (1). ) on the left and right sides, 16mm to 26mm away from the center of the pipe neck, each attaches a magnetic block (3) with a magnetic flux of 0.96mT, the S pole of the left magnetic block is downward, and the S pole of the right magnetic block is upward;
[0047] 5). Use the color-purity converging magnetic piece installed on the tube neck to readjust the converging state of the blue, green and red beams in the center of the screen to make it meet the general manufactur...
