Abstract
The embodiment of the utility model discloses a steam checking machine which relates to the field of liquid crystal displays, and can realize uniform steam dispersion and improve the detection success rate and the product yield. The steam checking machine provided by the embodiment comprises a steam cabin for producing steam, a plurality of primary dispersion devices and a secondary dispersion device, wherein the plurality of primary dispersion devices are respectively connected with the steam cabin and are respectively connected with the secondary dispersion device; and the steam which is produced from the steam cabin is dispersed for the first time through the primary dispersion devices, and then enters the secondary dispersion device to be dispersed for the second time. The steam checking machine is applied to substrate detection during a liquid crystal display production process.
Description
Technical field
The utility model relates to field of liquid crystal, relates in particular to a kind of steam inspection machine.
Background technology
The steam inspection machine is that high-temperature water vapor is distributed to glass baseplate surface, because the influence of friction process, under illumination, hackly glass baseplate surface generation diffuse reflection, thus can reflect that glass baseplate surface is through the situation behind the friction process.
The steam inspection machine that prior art provides is drawn shower nozzle from steam compartment; Shower nozzle ejection water vapor; And appoint steam freely to be diffused on the glass baseplate surface; There is following defective in this steam inspection machine: when shower nozzle was worked, water vapour can receive the influence that ambient air flows in diffusion process, cause water vapour at the product surface skewness; Under the bigger situation of glass substrate, can't adhere to steam fully, thereby can not detect fully; If preliminary infusion is too much in the steam compartment, just have the globule and sputter at glass baseplate surface from shower nozzle, influence testing result, and the globule that sputters at substrate surface possibly also can influence post-order process, cause product bad.
The utility model content
The utility model technical matters to be solved is to provide a kind of steam inspection machine, realizes the even diffusion of steam, has improved to be detected as power and also to have increased the product yield.
For solving the problems of the technologies described above, the utility model steam inspection machine adopts following technical scheme:
A kind of steam inspection machine comprises: be used to produce the steam compartment of steam, also comprise:
Several disperser is connected with said steam compartment respectively;
The secondary disperser, said several disperser are connected with said secondary disperser respectively;
The steam that said steam compartment produces enters into said secondary disperser secondary diffusion after a said disperser once spreads.
Be connected through steam hose between said steam compartment and the said disperser.
A said disperser is a shower nozzle.
Also comprise:
Be arranged on the track of said secondary disperser side, said steam inspection machine moves back and forth along the orbital direction of said track.
In the technical scheme of present embodiment; Carried out the secondary diffusion through the water vapour of secondary disperser after to the diffusion of disperser; Make water vapour equably attached to the examine substrate surface, improved effectively and be detected as power, reduce false drop rate; Reduce the loss that error-detecting causes, improve product quality; Reduce the sputter of the steam compartment globule, the influence of avoiding substrate surface and back technology therefore to cause improves yields.
Description of drawings
In order to be illustrated more clearly in the utility model embodiment or technical scheme of the prior art; The accompanying drawing of required use is done to introduce simply in will describing embodiment below; Obviously, the accompanying drawing in describing below only is some embodiment of the utility model, for those of ordinary skills; Under the prerequisite of not paying creative work, can also obtain other accompanying drawing according to these accompanying drawings.

Embodiment
The utility model embodiment provides a kind of steam inspection machine, realizes the even diffusion of steam, has improved to be detected as power and also to have increased the product yield.
Below in conjunction with accompanying drawing the utility model embodiment is described in detail.
The utility model embodiment provides a kind of steam inspection machine, and is as shown in Figure 1, and this steam inspection machine comprises: be used to produce the steam compartment (not shown) of steam, also comprise: several disperser 1 is connected with said steam compartment respectively; Secondary disperser 2, said several disperser 1 are connected 2 with said secondary disperser respectively; The steam that said steam compartment produces enters into said secondary disperser 2 secondaries diffusion from said.Particularly; The water vapour that gives out from steam compartment is under the effect of steam compartment internal pressure; Once spread the back from several disperser 1 and in secondary disperser 2, fully merge diffusion; Make water vapour to diffuse out equably along the outlet of secondary disperser 2, thus make water vapour can be equably attached to the substrate surface of the examine that is positioned at steam inspection machine top.And; Further, the globule that steam compartment sputters will be more attached to the inwall of disperser 1 and secondary disperser 2, reduced the possibility that sputters at substrate surface; The influence of further having avoided substrate surface and back technology therefore to cause improves yields.
Further, be connected through steam hose 3 between said steam compartment and the said disperser 1.Because the pressure of steam compartment interface is bigger; Make water vapour spray from interface, via 3 to dispersers 1 of steam hose again to secondary disperser 2, because sectional area increases gradually; Effectively reduce water vapor pressure, make water vapour evenly come out lenitively.And; Be connected through steam hose 3 between steam compartment and the said disperser 1; Make a disperser 1 that is fixed together to carry out the switching of all angles with secondary disperser 2; Thereby the steam outlet of realizing secondary disperser 2 is to each angle direction diffusion water vapour, can make steam easily, accurately and equably attached to each surface location of substrate.
Further, in this enforcement, an above-mentioned disperser 1 is preferably shower nozzle, and several shower nozzles evenly distribute, and wherein the quantity of shower nozzle is provided with according to actual needs, and present embodiment does not limit.
For large-sized glass substrate; In order to make monoblock substrate attached water steam equably; Can secondary disperser 2 be moved back and forth below the examine substrate, therefore, can the track (not shown) be set at said secondary disperser 2 sides; Said steam inspection machine can move back and forth along the orbital direction of said track, thereby makes that water vapour can be equably attached on the large-sized examine substrate of monoblock.
In the technical scheme of present embodiment; Carried out the secondary diffusion through the water vapour of secondary disperser after to the diffusion of disperser; Make water vapour equably attached to the examine substrate surface, improved effectively and be detected as power, reduce false drop rate; Reduce the loss that error-detecting causes, improve product quality; Reduce the sputter of the steam compartment globule, the influence of avoiding substrate surface and back technology therefore to cause improves yields.
The above; Be merely the embodiment of the utility model; But the protection domain of the utility model is not limited thereto; Any technician who is familiar with the present technique field can expect changing or replacement in the technical scope that the utility model discloses easily, all should be encompassed within the protection domain of the utility model.Therefore, the protection domain of the utility model should be as the criterion with the protection domain of said claim.
