Abstract

The utility model belongs to a soft magnet, particularly a soft magnet compensation material which is used when a color picture tube neck assembly is assembled and landing compensation is adjusted. The utility model comprises a magnet of which the material is soft magnet composite material which is composed of magnetic powder and synthetic resin binder, and the magnet forms a V shape. One end of the magnet is N pole and the other end is S pole. The magnet can be in excellent contact with the cone of the picture tube and avoid or reduce magnet dropping percentage in order to ensure the red, the green and the blue three electron beams beating at corresponding tricolor phosphor strips in the entire screen and increase the color purity performance of the color picture tube.

Description

The color picture tube neck assembly assembles and is adjusting the screen compensation magnets
One, technical field
The utility model relates to a kind of soft magnetic bodies, particularly a kind of to color picture tube neck assembly assembling with adjusting the screen compensation magnets.
Two, background technology
Assembling of color picture tube neck assembly and adjustment are last procedures in the whole color picture tube manufacture process, and its quality of adjusting quality directly affects the image quality of color picture tube.When assembling of color picture tube neck assembly and adjustment, need to color picture tube screen adjust and check, guaranteeing that three electron beams of red, green, blue are beaten on each self-corresponding three toner bar in whole panel, thereby guarantee the colour purity performance of color picture tube.Therefore the quality that should adjust quality directly influences the tone rendering of color picture tube installation back-television set to colour picture.
Because factors such as technological fluctuation and manufacturing of each parts and rigging error, to color picture tube screen when adjusting, screen in limit, the part, bight of face often can not meet the demands, this moment just need be at the corresponding position of color picture tube cone, the material that has magnetic in the stickup relies on additional magnetic force, compensates facing to screen, make this local electron beam stressed, produce displacement and correct screen.
Traditional to color picture tube the magnetic material that compensates of screen mostly be hard magnetic body, shape mostly is rectangle or circle.Because the magnetic patch of hard magnetic body is thicker, and with the pipe cone between contact defective tightness, particularly be subjected to external force to do the time spent, stick on easier dropping on the pipe, and the magnet of soft magnetic bodies increases than Hard Magnetic piece adhesive property.But the large-screen pipe is being carried out when compensation screen and since screen compensation area increase, the area corresponding requirements of magnet, magnetic patch is increased.Because the picture tube outer surface of cone is an on-plane surface, the big magnet of rectangle sticks on the cone and also drops easily, and influences presentation quality.
Three, summary of the invention
In order to overcome above-mentioned weak point, goal of the invention of the present utility model provides a kind of can the contact with the cone of picture tube is fine, stop or reduce the probability that drops of magnet, ensured color picture tube neck assembly assembling that picture tube screen and colour purity performance and adjusted the screen compensation magnets.
The color picture tube neck assembly assembles and is adjusting the screen compensation magnets, comprises magnet, and its improvements are, the soft magnetic bodies composite material that magnet material adopts magnetic powder and synthetic resin cement to constitute, and its magnet shape is " V " shape.
Four, description of drawings
Accompanying drawing is a structural representation of the present utility model.
Five, embodiment
Accompanying drawing is a specific embodiment of the utility model;
Below in conjunction with accompanying drawing technology contents of the present utility model is described further:
The color picture tube neck assembly assembles and is adjusting the screen compensation magnets, comprises magnet 1, the soft magnetic bodies composite material that magnet material adopts magnetic powder and synthetic resin cement to constitute, and magnet 1 is shaped as " V " shape.
In the process of assembling of color picture tube neck assembly and adjustment, need to color picture tube screen adjust and check, guaranteeing that three electron beams of red, green, blue are beaten on each self-corresponding three toner bar in whole panel, thereby guarantee the colour purity performance of color picture tube.When to color picture tube screen when adjusting, on the limit of face, when the part at angle screen and all can not meet the demands, can use this compensative material that it is compensated this moment.Its course of work is: at first tear the two-sided tape protection sheet on this magnet off; in the picture tube face near the cone position of the correspondence of shielding the position that do not meet the demands; make this magnet plane approaching as far as possible with the awl plane; rotate the pole orientation of this magnet with hand; make desire compensation position screen state the best; keep pole orientation constant; move this magnet positions before and after again on the conical surface; after making the compensation position the screen state and meet the demands; this magnet is close to this position of cone can satisfying the screen requirement; guarantee in whole panel red; green; blue three electron beams are beaten on each self-corresponding three toner bar, improve the colour purity performance of color picture tube.Adopt this kind structure easy to use, cost is low, can extensively be used in the large-screen colored picture tube screen compensation.
