Abstract
A clamping device includes the stainless steel carriage, the upper and lower two pieces of toughened glasses, on the carriage, the flat panel display part positioned between the toughened glasses. Several toughened glass pad pillars cut from same plate are evenly distributed between the upper toughened glass and the stainless steel plate which is above the glass, as well as between the lower toughened glass and carriage. Under effect of these evenly distributed pad pillars, the temperature differences of each point on the flat panel display screen in not more than 2 deg.C. Thus, the invented reasonable clamping device makes display screens be heated evenly forming the flattening plane of screens so as to provide the good condition of successful sealing operation.
Description
Technical field
The invention belongs to vacuum type flat-panel display device manufacturing technology field, the anchor clamps that particularly a kind of planar display device is used.
Background technology
The main process of vacuum type planar display device is to be coated in the glass powder with low melting point slurry on the sealing ring equably, remain on certain height and certain width, heat treated in baking oven then makes the low-melting glass fusing and flat-panel display device cathode base and anode substrate is bonded to each other together.Because the panel display screen spacing between the two substrates glass up and down has only hundreds of microns, will guarantee in the sealing-in process that two substrates glass can be fully parallel, the anchor clamps that must have the pinpoint accuracy sealing-in to use.Simultaneously, in order to make that in the sealing-in process, panel display screen can be heated equably, make that display screen does not break in the sealing-in process, guarantee sealing-in quality and high rate of finished products, the anchor clamps that use sealing-in rational in infrastructure to use are most important.
The anchor clamps that existing planar display device is used have two kinds usually, and a kind of metal holder that is to use clamps panel display screen up and down around the two substrates glass.Because in the sealing-in process, between needing to heat 400 ℃ to 500 ℃, and keep one or two hour, used metal holder deforms behind high-temperature baking several times and loss resilience easily, can't repeatedly use repeatedly, this anchor clamps itself need special metal material simultaneously, and price is also somewhat expensive, therefore cause with high costs.On technology,, can only be clipped in four corners and the edge of display screen, and elasticity is smaller, can't guarantee panel display screen closely being closed between the two substrates up and down because this metal fixture is smaller.Concerning the large-area flat-plate display, because part does not have stressed outside the metal fixture clamping point, in the sealing-in process, be easy to arch upward, cause between the sealing-in rear plate display screen two substrates not parallel, gap difference between the two substrates is bigger, reduce the quality of sealing-in screen, had influence on the performance of display screen.Another kind of sealing-in anchor clamps are directly with two plate glass display screen to be clipped in the middle, though problem that this anchor clamps can eliminate that glass arches upward etc., but fail to guarantee that sealing-in process middle plateform display device can be parallel to each other between the two substrates up and down, and because the plate glass anchor clamps itself are the non-conductors of heat, have a temperature gradient with the centre around can causing display screen, display screen breaks in the sealing-in process because of non-uniform temperature causes easily.
Summary of the invention
In order to overcome above-mentioned deficiency, the purpose of this invention is to provide the sealing-in anchor clamps that a kind of follow-on flat panel display is used, it can make flat-panel display device stressed and be heated evenly in whole sealing-in process, thereby guarantee that upper and lower base plate glass can be parallel to each other, do not break in the sealing-in process, improved the sealing-in quality.
The object of the present invention is achieved like this:
The present invention comprises the stainless steel bracing frame and places two toughened glass up and down on the bracing frame, flat-panel display device places between two toughened glass, there is a corrosion resistant plate to be pressed on the toughened glass of upper strata, it is characterized in that having some contour pad posts to be uniformly distributed between upper strata toughened glass and the corrosion resistant plate, and be uniformly distributed between lower floor's toughened glass and the stainless steel bracing frame.
Described pad post is toughened glass pad post or ceramic blanket post.
The spacing that between the described pad post with the distance is 50mm～100mm evenly distributes, and forms pad post square formation.
Described pad post is that the length of side is 10mm～15mm, and height is the toughened glass tetragonal prism of 20mm～60mm.
Described toughened glass pad post is that the some length of sides are 10mm～15mm, and height overlaps for the toughened glass tetragonal prism of 10mm～20mm.
Described corrosion resistant plate heavily should be looked screen size and be decided to be 20Kg～80Kg.
The present invention has solved flat-panel display device unreasonable variety of issue that occurs owing to clamp structure in the sealing-in process effectively, under the effect of equally distributed pad post, it can make panel display screen each point temperature differ and be no more than 2 ℃, thereby make panel display screen energy thermally equivalent, and can form very smooth plane, make the panel display screen each point stressed equal, thereby successfully have laid a good foundation for sealing-in.
Description of drawings
Fig. 1 is the structure chart of invention.
Specific implementation method
As shown in Figure 1, the present invention is made up of stainless steel bracing frame 1, toughened glass 2,4,6,7, some pad posts 3 and a slice corrosion resistant plate, and tiling a slice toughened glass 2 can flatly be placed the panel display screen on it on stainless steel bracing frame 1.On toughened glass 2, be evenly distributed with some pad posts 3, this pad post 3 is that the some length of sides that cut down by order on same block of sheet material are 10mm～15mm, height stacks for the toughened glass tetragonal prism of 10mm～20mm, also useful ceramics pad post, the height of each pad post all equates, forms pad post square formation 9.Identical according to this method can form pad post square formation 10 and pad post square formation 11.Wherein remain on the distance of 50mm～100mm between each pad post, the heat in the baking oven can waltz through between each blockage along with the air-flow that air blast took to of baking oven like this, and has guaranteed evenness, has guaranteed thermal uniformity again.Having folded up flat-panel display device 5 between two thickness are toughened glass 4,6 about 3mm is placed on the square formation 9.Stacking pad post square formation 10, toughened glass 7, pad post 11 and weight on it successively is the corrosion resistant plate 8 of 50Kg～100Kg, wherein filling up a slice thickness respectively at the upper and lower surface of panel display screen is toughened glass about 3mm, mainly be for the each point temperature that makes panel display screen is more even, corrosion resistant plate then is for two plate base glass up and down closely being bonded together.
With the method for above-mentioned making pad post, solved effectively in the panel display screen sealing-in process, owing to fixed precision causes the uneven defective of panel display screen two substrates after the sealing-in inadequately.With the placement schemes of the above-mentioned panel display screen that proposes, solved the even problem of heat in the panel display screen sealing-in process effectively simultaneously.
