Description
The present invention relates to the joining electronic parts of a kind of glass and metal, in more detail, relate to burn till glass component is engaged with hardware when becoming one by heating, prevent from crackles such as dry and cracked and scar take place near the glass component the bonding part, and improve the glass of precision and the joining electronic parts of metal.
The panel part of teletron is coated with red, green, blue 3 primary colours, and used electron tube electron beam gun such as colored visualization machine are towards making the luminous fluorescent screen emission electron beam corresponding with each 3 primary colours of these 3 primary colours.Electron beam will cover whole patterns ground by electromagnetic field and carry out deflection scanning, and video is reproduced.This electron tube has array or the assortment in one plane of assortment at certain intervals to become triangular form with electron beam gun, but all must be adjusted to 3 electron beams launching with electron beam gun by electron tube and on window of tube, concentrate on 1 point separately, this is adjusted when insufficient, can produce colour cast on image.
As the example of electron tube with electron beam gun, the electron tube that Fig. 3 (a) expression is made of negative electrode, G1 electrode (the 1st gate electrode), G2 electrode (the 2nd gate electrode) longitudinal sectional view of electron beam gun.This electron tube is with electron beam gun 20, and it has the front portion of the minim gap faces cathode 21 of the G1 electrode 22a of micro-holes and about 50-200 μ m, G2 electrode 22b with the arranged spaced of about 50-350 μ m after G1 electrode 22a.Stacked again G3-G6 electrode becomes the parts of electronic gun as composite part.
Electron tube is to burn till and engage with 27 heating of metal system housing by the cylindraceous metal negative electrode keeper 25 with glass 23, formation negative electrode 21 to make with electron beam gun 20.In other words, with the through hole that is provided for 3 negative electrode keepers 25 are inserted with becoming row, and be configured as the blocky glass 23 of platelet by compressing tablet shaping etc. and be housed in bottom surface sections and be provided with in the metal system housing 27 of peristome, and be fixed on and do not give on the illustrated anchor clamps.Then, after in 3 negative electrode keeper 25 patchholes, heat and burn till, glass 23, negative electrode keeper 25, metal system housing 27 is engaged and become one.Afterwards, G1 electrode 22a is placed on the negative electrode 21, again that G2 electrode 22b is thereon stacked, to finish manufacturing.
But using the stacked operation of negative electrode, G1 electrode and the G2 electrode of this method mainly is to carry out with handwork, thereby time-consuming and low precision, is the big operation of error.Therefore, now become in advance, heated and burn till and engage, made the incorporate electron tube of each member with electron beam gun (with reference to Fig. 3 (b)) with manufacturing with negative electrode, G1 electrode, G2 electrode layer poststack.
This electron tube roughly is with the bottom expansion of the G2 electrode 22b of the existing electron beam gun 20 shown in Fig. 3 (a) with electron beam gun 30 and bends to container-likely, becomes the structure that G1 electrode and negative electrode is contained in its inboard.The electron tube of this pattern is that negative electrode 31, G1 electrode 32a and G2 electrode 32b, glass 33 heating are burnt till with electron beam gun 30, realizes each member engages integrated.
At this, the big factor that hinders metal and glass bond is the stress-strain that the difference of the thermal contraction (thermal expansivity) of metal and glass in the process of cooling after burning till causes.Adopt as the general thermal expansivity of the glass that uses with metallic joint and to be 4.5-6.5 * 10 30-500 ℃ the time
-6/ ℃, for reducing this strain, be to use the Fe-Ni class alloy close with the thermal expansivity of glass as hardware.
Table 1 expression Fe-Ni is the thermal expansivity of alloy.
The thermal expansivity of table 1 Fe-Ni class alloy
| Thermal expansivity (10 -6/℃) | 42 alloys | Kovar alloy | Fe (soft steel) * |
| ?30-300℃ | ????4.1 | ????4.9 | ????13.0 |
| ?30-400℃ | ????5.8 | ????5.2 | ????13.9 |
| ?30-500℃ | ????8.1 | ????6.1 | ????14.6 |
* reference
Be heated as the negative electrode keeper of parts of electronic gun electronics, become high temperature, thereby generally use the Kovar alloy (Fe-29%Ni-17%Co) that at high temperature thermal expansivity is low owing to emission of cathode.In addition, other hardwares are not owing to be heated to the such high temperature of negative electrode keeper, thereby mainly use cheap 42 alloys (Fe-42%Ni).
Parts of electronic gun is that the electrode of G1-G6 is overlapping, by the acceleration of the electronics of emission of cathode, inhibition, dispersion, convergence direction etc., thereby is strict with the positional precision of each part with control when assembling.In the past, once assembled the electrode of G1-G6, but, also developed part, and can realize the easy and the high precision int of assembling operation G1, compoundization of G2 electrode for improving operation with handwork.
By compoundization of parts of electronic gun, solved the problem when assembling, but produced problem again at generation crackle on glass.Fig. 3 is the sectional view of existing part with G1 electrode and compoundization of G2 electrode.The reason that the inventor etc. are taken place this crackle has been carried out investigation and has been found: during with G1 electrode and compoundization of G2 electrode, because the hardware with glass bond increases, in the process of cooling after glass burns till, produce because the strain that the thermal contraction difference of glass and metal causes, in addition owing to the reasons such as glass attenuation of part folded between hardware, generation crackle as a result.
In addition, the part for compoundization requires high-precision size.The span that passes through of the electronics of G1 electrode and G2 electrode wants the precision good control in ± 5 μ m specifically.In addition, when part is carried out compoundization, the shortcoming of glass attachment on the edge of negative electrode keeper taken place also when the burning till of glass.When glass attachment on the negative electrode keeper, by the emission of cathode electronics time, the Ba ion of negative electrode is attached on its periphery, causes conduction, hinders the insulativity of glass.
Studied the whole bag of tricks for preventing to crack on glass, the result finds out: the hardware of use, the thermal expansivity of its metal in the time of 30-500 ℃ is glass in the scope of the 70-130% of the thermal expansivity of synthermal scope the time, can obtain good result.In other words, as shown in table 1, the material coefficient of thermal expansion coefficient shows different values according to each temperature, and it is worth according to temperature range, and the situation of reverse is also arranged at storeroom.Situation when the inventor etc. only investigate glass and burn till with regard to the relation of the thermal expansivity of the strain temperature of glass and thermal expansivity, metal is found: even such composite part, when glass and metallic joint, as mentioned above, if the thermal expansivity of metallic substance in the time of 30-500 ℃ is in the scope of the 70-130% of glass the time, suit for joint.
The object of the present invention is to provide a kind of optimum range of finding out in according to the present invention, even the difference that adds thermal expansivity of used glass component and hardware is big, burn till and when engaging heating, what crackles such as dry and cracked and scar can not take place near the glass component the bonding part yet comprises that electron tube is with the glass of electron beam gun and the joining electronic parts of metal.In addition, its purpose also is to provide simultaneously the glass of raising precision and the joining electronic parts of metal.
