[Prior Art 3] For example, in the manufacturing process of the plasma display panel, there is a step of sealing the 10-terminal tube to the vent hole portion constituting one of the glass panels to the glass panel member. Conventionally, as shown in Fig. 9, the sealing treatment of the end tube is such that the open end of one of the glass end tubes 12 is hermetically held outside the exhaust head 11, and the other end portion 13 is opened. It is roughly concentrically placed in the vent hole portion 15 of the glass panel 14, and is placed in the furnace in a state where the glass panel 15 member 29 and the glass end tube 12 are integrally fixed by the clip 32. Specifically, the exhaust head 11 has an end tube loading space 11 formed at a center portion, and an elastic member formed in the end tube loading space 16 to form a hollow annular sealing portion 17; An annular water-cooling jacket 18 around the circumference of the annular seal portion 17; and the upper end surface member 19 and the lower end surface member 21 of the member are held up and down. The exhaust head 11 itself is supported by the fixed frame 23 via a spring 22 provided below the upper end surface member 19. Further, the 24 series exhaust pipe, the 26-series cooling water supply pipe, and the other 27 are the cooling water discharge pipes. 1280602 发明, the invention shows that the end tube 12 has a funnel-shaped open end 13 on the upper side of the fusion side, and the lower part of the fixed diameter of the end tube 12 is the inlet 28 of the upper end member 19, which penetrates the annular seal 17 is disposed at a predetermined position within the end tube loading space 16. In this state, the outer peripheral portion of the end pipe 12 can be hermetically held by the annular seal portion 17 which is expanded by the compressed air supplied from the compressed air flowing into the pipe 25 5 . The glass panel 14 is composed of a pair of glass members 29 and has a vent hole portion 15 at the lower portion. The vent hole portion 15 is in contact with the opening end portion 13 of the slightly concentric end tube 12 via the glass paste for fusion (glass frit) 31. Further, the glass panel 14 and the end tube 12 are integrally fixed by the sinker 32 which forms a notch portion at the end portion of the lower sheet. Further, the glass panel 14 is placed on the panel supporting member 5A of the base 5, and the panel supporting member 5A of the base 5 and the fixing frame 23 are held in a fixed positional relationship. The fixing frame 23 and the aforementioned base 5 are provided on, for example, an exhaust vehicle. Further, in this state, the end pipe 12 and the glass panel 14 held in the exhaust head 11 are placed in the furnace, and the end pipe 12 and the glass panel 14 are sealed by heating. SUMMARY OF THE INVENTION PROBLEM TO BE SOLVED BY THE INVENTION In the sealing method of the above-described conventional end tube 12 and glass panel 14, during the transportation, heating, sealing treatment, and the like, the above-mentioned respective portions should maintain a relative fixed positional relationship, but due to vibration and impact, or thermal expansion. The difference between the contraction and the contraction causes a relative positional shift between the exhaust head 11 and the glass panel 14. In this case, for example, when the annular seal portion 17 acts on the end tube 12 at 1,280,602, the force of the invention is too large, the force is greater than the force that integrally fixes the glass panel 14 and the end tube 12, and the end is The tube 12 is broken by the inclination of the clip 32, or the glass paste 31 is separated from the underside of the glass panel 14, and the sealing process cannot be performed. Further, when the relative position between the exhaust head 11 and the glass panel 14 in the horizontal direction is shifted, the exhaust head 11 cannot be moved in parallel and inclined. In this case, an improper force such as rotation may act on the end tube 12, and an excessive bending moment acts on the end tube 12 to tilt the end tube 12, causing the end tube 12 to be broken or unable to be sealed. The situation arises. [Explanation of the Invention] In order to solve the above problems, in the sealing method of the end pipe which is sealed to the end portion of the vent hole of the glass panel, the end pipe is constructed such that The opening end of the melting side faces upward, and the end pipe is held 15 on the exhaust head supported by the pressing member that generates the reaction force, and the opening end is pushed by the reaction force of the pressing member. The state of the vent hole portion under the glass panel is pressed, and the sealing treatment is performed in this state. Further, the present invention is configured in an exhaust head for holding a 20-end tube sealed to a vent hole portion of a glass panel, comprising: a space portion for evacuating the vacuum, and a peripheral portion for the end tube The annular seal portion is hermetically held in the space portion, and the exhaust head is supported by the pressing member that generates the reaction force and is formed to be displaceable only in the vertical direction. 1280602 发明, DESCRIPTION OF THE INVENTION t 3 EMBODIMENT OF THE INVENTION Hereinafter, an embodiment of the present invention will be described with reference to Fig. 1 . Figs. 1 and 2 show an exhaust head 1A and a peripheral portion thereof for use in a sealing method for the end pipe 12 of the present invention, and a portion common to the respective portions of the structure shown in Fig. 9 (4) and The same reference numerals are used and the description is omitted. In the structures shown in Figs. 1 and 2, a slide guide 2A is provided between the fixed stand 23 and the lower end member 21. The sliding guide portion 10 is composed of a cylindrical body 3 and a rod member* slidably inserted into the cylindrical body 3. The cylindrical body 3 is fixed to the lower surface of the fixed frame 23, and the rod member 4 is It is erected on the lower end surface member 21. Further, the sliding guide portion restricts the exhaust head 1 to relatively move laterally to the fixed frame 23, and can only move in the up and down direction. Next, the operation of the exhaust head 1 15 will be described with reference to Figs. 3 to 6. Eight y First, as shown in Fig. 3, the exhaust head 1A is prepared such that the end pipe U of the open end portion 13 of the glass paste 31 is placed directly above the end pipe charging space 16 as shown in Fig. 4 The lower portion of the end tube 12 is loaded into the loading space 16 by the loading port 28, and the compressed air is sent to the annular seal ... to airtightly hold the outer circumference of the end tube 12 by the annular sealing portion 17: here The lower end is the upper end of the upper end of the melted side of the end tube 12, and the upper end is higher than the lower surface of the base 5 that is placed on the exhaust vehicle, for example, located above (1). The glass panel is next as shown in Fig. 5, so that the open end portion 13 of the end tube 12 is slightly the same as the through hole 20 1280602, and the vent portion 15 is kept in the same state, and as shown in Fig. 6, The glass panel 14 is charmed on the aforementioned base 5. As a result, the end pipe 12 is pressed downward by the weight of the glass panel 14, and when the above-mentioned amount is decreased (for example, 1 to 3 mm), the open end portion 13 becomes a spring 5 spring 22 which is an example of a pressing member. The reaction force is pressed against the vent hole portion 15 via the glass paste 31. At this time, the end pipe 12 is not subjected to the lateral force by the sliding guide portion 2A, and can be displaced only in the up and down direction. 10 15 Next, in this state, the end tube 12 and the glass panel 14 are simultaneously charged into the furnace and heated according to a predetermined heating curve, and then the end tube 12 and the glass panel 14 are sealed. Since the friction between the glass paste 31 and the glass panel 14 is greater than the friction between the glass panel 14 and the base plate 5 by the above-mentioned open end portion η toward the vent hole portion 15, the sealing step is performed in the sealing step. The 'heated' panel 14 is expanded with the vent hole portion 15 pressed by the σ end portion 13 as a base point, and the positional displacement between the opening end portion 13 and the vent hole portion 15 does not occur. Further, in the sealing treatment step, even if the glass panel 14 generates a material, since the end tube 12 is biased upward by the spring 22, no gap is formed between the glass panel 14 and the glass paste 31. In the seventh embodiment and the description, the exhaust head 1Β and its peripheral portion for the other methods of the end pipe of the present invention are applied. (4) The parts of the structure shown in Fig. 2 and the second embodiment are given the same reference numerals and are omitted. . In the exhaust head 1B, the sliding guide bow portion 2 attached to the lower surface of the solid σ 23 is disposed near the water-cooling jacket > π solid < 3 or more. Further, by the sliding guide portion 2β, the lateral displacement of the nipple 1Β is restricted, and the invention is described, and only the displacement in the up-and-down direction is allowed, and the same effect as described above can be produced. Furthermore, the pressurizing member of the present invention is not limited to the spring 22, and may be any member that can generate a reaction force. In addition to the spring 22, for example, the principle is used to make the exhaust head 1A opposite to the fixed frame 23. The upward trend of 5 can also be. Further, the pressing member may include a cam mechanism and a mechanism for using a weight. According to the invention of the present invention, the opening end portion of the melt side of the end pipe sealed to the vent hole portion of the glass panel is upwardly held on the exhaust head 10 and the open end portion is provided. The vent hole portion under the glass panel is pressed, and the sealing process is performed in this state. That is, since the glass panel and the end tube are integrally fixed without a clip for sealing treatment, it is possible to avoid impact or vibration when the end tube and the glass panel are loaded into the furnace, or to perform sealing and vacuum evacuation treatment. When the thermal deformation caused by the difference between the thermal expansion and the contraction of the respective portions 15 causes an excessive force to act on the end, in particular, the force for rotating the end tube by the side can be avoided, and the damage caused by the clip can be prevented. The damage of the tube can also achieve the effects of simplifying the early preparation of the sealing treatment and improving the reliability thereof. Further, according to the second aspect of the invention, the exhaust head that is kept sealed to the end pipe of the glass panel is supported by a spring, and is formed to be displaced only in the up and down direction. Therefore, the male and the sealed end pipe are pressed toward the glass panel. And the vertical direction is maintained, and the direction force other than the vertical direction does not act on the end tube, and the effect of easily maintaining the pushing state of the end tube can be achieved. 10 1280602 & Description of the Invention [Simple description of the cabinet] Fig. 1 is a cross-sectional view showing the application of the end pipe of the present invention, the exhaust head and its peripheral portion.
