Abstract
The invention discloses a vent pipe of a plasma display screen, comprising a pipe orifice and an S-shaped pipe body, wherein the pipe orifice is suitable for aligning with a vent hole of the plasma display screen; the S-shaped pipe body extends from the pipe orifice; and the S-shaped pipe body comprises at least three columnar straight pipe sections and transition bent pipe sections connected between every two adjacent columnar straight pipe sections. Sealing can be carried out for two times and even more times without grinding a connecting port of the vent pipe and a screen substrate, and the invention has reliable air tightness and high success ratio.
Description
Technical field
The present invention relates to the plasma display field, in particular to a kind of blast pipe of plasma panel.
Background technology
In plasma panel, discharge gas is sealed between the two sheet glass substrates with a plurality of electrodes.After the energising, discharge gas produces ultraviolet ray, and the ultraviolet ray excited fluorescence coating that forms in predetermined display unit sends visible light, forms image by this visible light.
In the manufacture process of plasma display panel (PDP),, need article on plasma body display screen to vacuumize charging into before the working gas.
Plasma panel is got rid of the foreign gas that is sealed in two sheet glass substrates and is charged into specific plasma gas by the blast pipe of the overshooting shape that is positioned at the bight usually.In order to make plasma display panel (PDP) become the product of separation instrumentation, blast pipe need be carried out sealing-in, be about to blast pipe and fuse from the centre, make plasma display panel (PDP) and device separates.Plasma display panel (PDP) just can flow to next process then, the promptly seasoned and inspection operation of lighting a lamp.
In the sealing-in, need a large amount of new screens or the screen that polishes sealing-in repeatedly to experimentize, consumed a large amount of labor costs and raw material experimental cost greatly the sealing-in of gas mixing ratio experiment.
Summary of the invention
The object of the invention is to provide a kind of blast pipe of plasma panel, and the connector that the blast pipe of this plasma display screen need not polish blast pipe and panel substrate can carry out 2 times even sealing-in repeatedly.
For this reason, the blast pipe of plasma panel provided by the invention comprises: the mouth of pipe, be suitable for the steam vent contraposition with plasma panel, and the S bend pipe body extends from the mouth of pipe.
Wherein, above-mentioned S bend pipe body comprises at least three column straight lengths and is connected in transition bend loss between the adjacent two column straight lengths.
Wherein, above-mentioned S bend pipe body comprises five column straight lengths and is connected in transition bend loss between the adjacent two column straight lengths.
Wherein, the above-mentioned mouth of pipe is a horn mouth, and this horn mouth is provided with low glass ring, and this low glass ring is suitable for connecting plasma panel and horn mouth when sealing-in.
Utilize blast pipe of the present invention, because the S shape of the pipe shaft of blast pipe, if need repeatedly sealing-in experiment, can block from pipe shaft, utilize the remaining part of blast pipe to carry out the experiment of sealing-in next time, need not polish the sealing-in mouth of blast pipe and screen according to existing method, air-tightness is reliable, the success rate height.
Except purpose described above, feature and advantage, the present invention also has other purpose, feature and advantage.Below with reference to figure, other purpose, feature and effect of the present invention is described in further detail.
Description of drawings
Accompanying drawing described herein is used to provide further understanding of the present invention, constitutes the application's a part.Among the figure,
Fig. 1 shows the structure of the blast pipe of plasma panel of the present invention; And
Fig. 2 show among Fig. 1 blast pipe for the second time or the structure during more times sealing-in.
Embodiment
Below with reference to the accompanying drawings and in conjunction with the preferred embodiments, describe the present invention in detail.
Fig. 1 shows the structure of the blast pipe of plasma panel of the present invention, Fig. 2 show among Fig. 1 blast pipe for the second time or the structure during more times sealing-in.As depicted in figs. 1 and 2, the blast pipe of plasma panel of the present invention comprises: the mouth of pipe 1, be suitable for the steam vent contraposition with plasma panel, and the S bend pipe body extends from the mouth of pipe 1.
The S bend pipe body comprises three column straight lengths 21,22,23 and is connected in transition bend loss 41 between adjacent two column straight lengths 21 and 22 and the transition bend loss 42 between straight length 22 and 23.
The mouth of pipe 1 is the horn-like mouth of pipe, also is provided with low glass ring on the mouth of pipe 1, and low glass ring is suitable for connecting plasma panel and horn mouth when sealing-in.
When carrying out the sealing-in experiment, the mouth of pipe 1 is fixedlyed connected with the panel substrate steam vent, the mouth of pipe 3 and fixedly sealing-in of vacuum system can carry out the sealing-in first time like this.For the second time or during more times sealing-in, the transition bend loss 41 of straight length 21 or more of pipe shaft blocked, form new blast pipe, can realize the sealing-in second time like this.
Expect easily, pipe shaft of the present invention can also comprise more column straight length and be connected in transition bend loss between the adjacent two column straight lengths, for example 5 joint straight lengths or 7 joint straight lengths and be connected in adjacent two transition bend loss between directly perceived can form 3 times or 4 sealing-ins like this.
In other embodiments of the invention, the pipe shaft of blast pipe of the present invention can have, and the same transition bend loss that is suitable for connects between the adjacent straight pipeline section.
Use blast pipe of the present invention, need not polish the mouth of pipe 1 and the sealing-in mouth that shields, need not to use the sealing-in again of new blast pipe according to existing method.The S pipe shaft structure of blast pipe can realize 2 sealed-off when 3 straight lengths according to the present invention, can realize 3 sealed-off when 5 straight lengths.The repeatedly use of blast pipe, thus labour's cost and raw material experimental cost reduced, and also air-tightness is reliable, the success rate height.
Be the preferred embodiments of the present invention only below, be not limited to the present invention, for a person skilled in the art, the present invention can have various changes and variation.Within the spirit and principles in the present invention all, any modification of being done, be equal to replacement, improvement etc., all should be included within protection scope of the present invention.
