The device can be used as a diode and a triode. But this method is not the same as sealing a cathode ray tube. The present invention provides a method for sealing a cathode ray tube, in which a sealing plug and a three way branch tube (Three Way Branch Tube) covered with amorphous glass glue are used to extract the gas from the cathode ray tube until the sealing is completed. During the entire process, only the amorphous glass glue will melt. Figure 1A is a conventional method for extracting gas from a cathode ray tube and sealing the cathode ray tube. In the figure, the cathode ray tube 10 includes a neck portion 11 3 This paper size applies the Chinese National Standard (CNS) Λ4 specification (210X 297 mm) 494442 13 8 2 1 'VV 1' / .1 Λ S Ο Ν / 0 0 2 A 7 B7 V. Description of the invention (^) (Neck) and base 13 (Base). Among them, the neck 11 of the cathode ray tube 10 contains a cathode 14 and an electron gun 12; and on the base 13 of the cathode ray tube 10, there are several pins 16 for connecting with the filament, the cathode 14, and the electron gun 12; The base 13 of the cathode ray tube 10 has an exhaust hole 20 in addition, and the exhaust tube 18 is connected to the base 13 of the cathode ray tube 10 and covers the exhaust hole 20. The other end of the exhaust pipe 18 is connected to the pump pipe 22 with a 0-shaped pad 24 (0-Ring), and the other end of the pump pipe 22 is connected to a vacuum pump (not shown). The method is: when the pump tube 22 is evacuated, the gas in the cathode ray tube 10 is also evacuated, and after the gas in the cathode ray tube 10 is evacuated, the glass row near the substrate 13 of the cathode ray tube 10 is heated. The air pipe 18 melts a part of the exhaust pipe 18 and thereby seals the exhaust hole 20. Until the sealing is completed, the excess exhaust pipe 18 is removed. FIG. 1B shows the gasket 21 on the completed cathode ray tube 10. As shown in FIG. Printed by the Consumers' Cooperative of the Central Bureau of Standards, Ministry of Economic Affairs (please read the precautions on the back before filling this page). However, this conventional method of sealing the cathode ray tube 10 has some problems. When the glass exhaust pipe 18 is heated to seal the exhaust hole 20, the glass exhaust pipe 18 releases gas and is then sealed inside the cathode ray tube 10. These C-H gases increase the pressure in the cathode ray tube 10, which indirectly affects the operating characteristics and life of the cathode ray tube 10, and these gases remaining in the cathode ray tube 10 cannot be absorbed by barium. Fig. 2A shows another conventional method for sealing a cathode ray tube using a vacuum high temperature furnace. In this method, the cathode ray tube 10 is placed in a vacuum high temperature furnace 62. The vacuum high temperature furnace 62 has a gap 64 and is connected to a vacuum pump (not shown). Pins 16, 4 This paper size is applicable to China National Standard (CNS) A4 (210X 297 mm) Printed by the Consumer Cooperatives of the Central Bureau of Standards of the Ministry of Economic Affairs 494442 1 382TW [: / JASON / O02 A 7 B7 V. Description of the Invention (Today) The cathode 14 and the electron gun 12 are as described previously. The cathode ray tube 10Z substrate 13 has a heat exhaust hole 20 ′ axis center 36 (which has a first end and a first * end). The younger end is connected to the linear moving device 3 8 and the first end of the shaft center 36. It is connected to a tray 34. The second surface of the gasket 32 (which has a first surface and a second surface) is placed on the tray 34, and the non-crystalline glass glue 30 is disposed on the gasket 32. The method is as follows: first, the gas in the cathode ray tube 10 is evacuated, and the vacuum high-temperature furnace 62 is heated to melt the amorphous glass glue 30; Push upward to the exhaust hole 20 and cool the vacuum high-temperature furnace 62, and the amorphous glass glue 30 and the gasket 32 will condense on the exhaust hole 20 and seal it. Please refer to FIG. 2B. This method of using a vacuum high temperature furnace to extract the gas from the cathode ray tube and seal the cathode ray tube avoids the problems of the prior art, but because it is a batch process, it is slow and expensive. The main object of the present invention is therefore to provide an inexpensive method of sealing a cathode ray tube, which provides good vacuum characteristics and avoids leaving unwanted gases in the finished cathode ray tube. In order to achieve the above object of the present invention, the present invention uses a tee when extracting the gas in the cathode ray tube and the gas released from the amorphous glass glue. In the interim sealing process, only the non-crystalline glass glue will be melted '. Any gas generated in the cathode ray tube during the sealing process will be vacuum pumped II. Therefore, the present invention does not require a vacuum high-temperature furnace, and the heat source is provided by a high-temperature furnace that does not require batch operation.

Fig. 3 is a cathode ray tube 10 including a neck 51 and the base 13. The cathode ray tube 10 is additionally wrapped It includes a cathode 14, an electron gun 12, a filament (not shown), and a pin 16 that is welded to the substrate 13 for connection with the internal cathode 14, electron gun 12, and filament. On the substrate 13 of the cathode ray tube 10 There is an exhaust hole 20 with a diameter of about 3-5mm. The first end of the exhaust pipe 18 (which has a first end and a second end) has a trapezoidal section 60 (Tapered Section) which is welded to The outside of the base 13 of the cathode ray tube 10 is used to cover the exhaust hole 20, and the diameter of the second end of the exhaust tube 18 is about 10-20 mm. In the preferred embodiment, the material of the exhaust pipe 18 is glass. Printed by the Consumer Cooperative of the Central Bureau of Standards of the Ministry of Economic Affairs (please read the precautions on the back before filling this page) Place the cathode ray tube 10 and the exhaust tube 18 in a high-temperature furnace 42 with a hole on one side. The exhaust tube The second end of 18 protrudes from the opening on the side of the high-temperature furnace 42. The high-temperature furnace 42 may be a high-temperature furnace commonly used in the market. The tee 44 is made of stainless steel and has a first end 45, a second end 47, and a third end 46. The second end of the exhaust pipe 18 is connected to the first end 45 of the tee 44 by using a 0-type vacuum seal 37 (〇Ring Seal). A linear moving device 38, such as a vacuum actuator, is connected to the second end 47 of the tee 44. The shaft center 36 is located inside the tee 44 and can be made of glass, stainless steel or the like, and includes a first end and a second end.

Description of the Invention (f) The first end connected to the shaft center can be moved in the exhaust pipe 18 along with the shaft center 36 and the linear moving device 38. A vacuum pump (not shown) is connected to the third end 46 of the tee 44. A trapezoidal sealing plug 35 has a first surface, a second surface, and a trapezoidal surface, and the second surface is placed on the tray 34. The non-crystalline glass glue 30 covers the first surface and the trapezoidal surface of the sealing plug 35 and has the same trapezoidal surface as the sealing plug 35. First, the position of the tray 34 is adjusted by the linear moving device 38 so that the exhaust hole 20 is opened. Then, the vacuum pump starts to extract the gas from the cathode ray tube 10 so that the pressure in the cathode ray tube 10 is maintained at 4 X 10.5 To 5 X 10_6torr. Next, raise the temperature of the cathode ray tube, the sealing plug 35, and the amorphous glass glue 30 in the high-temperature furnace 42 to between about 400 ° C and 500 ° C, and let the amorphous glass glue 30 melt, as described in Section 4. As shown. Furthermore, the position of the tray 34 is adjusted by the linear moving device 38 so that the amorphous glass glue 30 contacts the trapezoidal section 60 at the first end of the exhaust pipe 18. The trapezoidal section 60 at the first end of the exhaust pipe 18 and the trapezoidal surface of the sealing plug 35 have the same trapezoidal angle. Then, the high-temperature furnace 42 starts to cool down, and the amorphous glass glue 30 is allowed to set. The sealing plug 35 and the condensed amorphous glass glue 30 are used to seal the exhaust hole 20. After that, the cathode ray tube 10 and the exhaust tube 18 are removed from the high-temperature furnace 42. The tee tube 44 and the exhaust tube 18 are cut off from the position of the point 33, and the sealing plug 35 is cut off below the point 33. Refer to Figure 5.
