Description
Technical field
The utility model relates to a kind of vacuum pumping hardware, particularly a kind of vacuum pumping hardware that is used for PDP display.
Background technology
In the prior art, the PDP display principle of luminosity is very simple, and it is also uncomplicated to make principle, takes a lot of work but manufacture process is consuming time.Can see from cost structure; The glass substrate cost only accounts for 15% of whole section PDP display panel cost; And manufacturing expenses have just accounted for 30% of total cost; Main cause is because the complex structure of prior art ionic medium screen vacuum pumping hardware, with high costs, and it is also more loaded down with trivial details in use to vacuumize and charge into the operation of inert gas.
The utility model content
To the deficiency that exists in the prior art, the purpose of the utility model be to provide a kind of simple in structure, cost is low and vacuumize and charge into the vacuum pumping hardware of PDP display under the non high temperature environment simple to operate of inert gas.
The technical scheme of the utility model is achieved in that the vacuum pumping hardware of PDP display under a kind of non high temperature environment; Comprise screen body blast pipe, wireway, filling with inert gas valve, vacuum pump main valve, inert gas bottle and vacuum pump; Said inert gas bottle is successively through inert gas tube connector and wireway and said screen body blast pipe fluid communication; Said vacuum pump is through wireway and said screen body blast pipe fluid communication; On the said inert gas tube connector filling with inert gas valve is installed, on the said wireway between the tie point of said inert gas tube connector and said wireway and the said vacuum pump vacuum pump main valve is installed.
The vacuum pumping hardware of PDP display under the above-mentioned non high temperature environment; Be communicated with the encapsulation blast pipe on the said wireway between the tie point of said inert gas tube connector and said wireway and the said screen body blast pipe, a gas valve is housed on the said encapsulation blast pipe.
The vacuum pumping hardware of PDP display under the above-mentioned non high temperature environment; On the said wireway between said vacuum pump main valve and the said vacuum pump vacuum measuring instrument is installed, on the said wireway between the tie point of said inert gas tube connector and said wireway and the said vacuum pump main valve vacuum measuring instrument is installed also.
The beneficial effect of the utility model is: (1) maximum vacuum can reach 1.0 * 10
-5Pa, vacuum pumping speed is not less than 4L/S.(2) simple in structure, cost is low and vacuumize and charge into the simple to operate of inert gas.

Among the figure: 1-PDP display upper glass plates, 2-PDP display lower glass plate, 3-screen body blast pipe; The 4-wireway, 5-gas valve, 6-filling with inert gas valve; The 7-vacuum measuring instrument, 8-vacuum pump main valve, 9-inert gas bottle; The 10-vacuum pump, 11-inert gas tube connector, 12-encapsulates blast pipe.
Embodiment
In conjunction with accompanying drawing the utility model is done further explanation:
Referring to Fig. 1; The vacuum pumping hardware of PDP display comprises screen body blast pipe 3, wireway 4, filling with inert gas valve 6, vacuum pump main valve 8, inert gas bottle 9 and vacuum pump 10 under the present embodiment non high temperature environment; Said inert gas bottle 9 is successively through inert gas tube connector 11 and wireway 4 and said screen body blast pipe 3 fluid communication; Said vacuum pump 10 is through wireway 4 and said screen body blast pipe 3 fluid communication; On the said inert gas tube connector 11 filling with inert gas valve 6 is installed, on the tie point of said inert gas tube connector 11 and said wireway 4 and the said wireway 4 between the said vacuum pump 10 vacuum pump main valve 8 is installed.Be communicated with encapsulation blast pipe 12 on the said wireway 4 between the tie point of said inert gas tube connector 11 and said wireway 4 and the said screen body blast pipe 3, a gas valve 5 is housed on the said encapsulation blast pipe 12.On the said wireway 4 between said vacuum pump main valve 8 and the said vacuum pump 10 vacuum measuring instrument 7 is installed, on the said wireway 4 between the tie point of said inert gas tube connector 11 and said wireway 4 and the said vacuum pump main valve 8 vacuum measuring instrument 7 is installed also.
The operation principle of the vacuum pumping hardware of PDP display is following under the present embodiment non high temperature environment: after the PDP display upper glass plates 1 of PDP display body seals with glue with PDP display lower glass plate 2 all around; With 3 sealing-ins of said screen body blast pipe on the PDP display body; Close said gas valve 5, said filling with inert gas valve 6 and said vacuum pump main valve 8; Start said vacuum pump 10; Open said vacuum pump main valve 8 then; After vacuum degree meets the demands in the chamber between said PDP display upper glass plates 1 and the said PDP display lower glass plate 2, close said vacuum pump main valve 8 and close said vacuum pump 10, open said filling with inert gas valve 6; Through charging into inert gas (luminous gas) in the chamber of said inert gas bottle 9 between said PDP display upper glass plates 1 and said PDP display lower glass plate 2, keep after 2-4 hour said screen body blast pipe 3 being separated with said wireway 4.
The present embodiment vacuum pumping hardware simple in structure, cost is low and vacuumize and charge into the simple to operate of inert gas.
The foregoing description only be for clearly explain the utility model create done for example, and be not the qualification of the utility model being created embodiment.For the those of ordinary skill in affiliated field, on the basis of above-mentioned explanation, can also make other multi-form variation or change.Here need not also can't give exhaustive to all execution modes.Any conspicuous variation of being extended out within all spirit and principles at the utility model or change still are in the utility model and create among the protection range of claim.
