Description
Technical field
The present invention relates to technical field of liquid crystal display, particularly relate to a kind of frame glue separating surface detection method and device.
Background technology
Along with the arrival of information age and popularizing of new technique, the application of liquid crystal display gets more and more.Liquid crystal display
Manufacturing process for produce TFT (thin film transistor (TFT)) and CF (colored filter) substrate respectively, be then coated with seal (frame glue) and make
TFT substrate and the adhesion of CF substrate, the liquid crystal in sealing frame.ODF (formula of dripping injection) coating process needs to add in frame sebific duct
Enter the seal/Au material frame glue that deaeration completes, utilize gas pressurized to make seal/Au material frame glue spue to base from nozzle (nozzle)
Position specified by plate.Frame glue is the important source material during liquid crystal panel produces, and its coating process and convenience are directly connected to processing procedure effect
Rate and material usage.
Seeing Fig. 1, it is frame glue wall cling phenomenon schematic diagram, and frame glue 2 imports in the cavity being stored in sebific duct 1 in advance, processing procedure
In outwards exported by the nozzle bottom sebific duct 1, owing to frame glue 2 has certain viscosity, frame segment glue 2 can stick to sebific duct 1
Inwall on, beyond the actual separating surface of frame glue 2.When new material imports, occur that frame glue " wall built-up " phenomenon makes separating surface fail to understand
Aobvious, personnel do not see frame glue separating surface, and in prior art, operator judge separating surface by experience or manual operation, cause
Cannot impregnation in time and change glue material, change and then cause too early material waste, change and the most then produce line generation fracture.The most accurate
Detecting frame glue separating surface is directly connected to material usage and process efficiency.
There is sebific duct " wall built-up " in existing frame glue coating process, the unconspicuous problem of boundary, for such problem, existing system
Journey solution is addition black piston in sebific duct, assists with the color of piston and judges.As in figure 2 it is shown, it is for solving
The prior-art illustration of frame glue wall cling phenomenon.Frame glue 2 imports in the cavity being stored in sebific duct 1 in advance, then adds and glue
The black piston 3 of the cavity minor diameter fit of pipe 1, connects at sebific duct 1 upper opening and has airway 4, and gas is inputted by airway 4
Sebific duct 1, as power, promotes frame glue 2 outwards to be exported by the nozzle bottom sebific duct 1.Sebific duct 1 uses transparent or semitransparent material
Making, after adding black piston 3, sebific duct 1 center glue 2 separating surface is more clear, can meet engineering and use.
But the shortcoming adding black piston is also apparent from:
One, piston matrix is macromolecular material, and is added with the additives such as pigment.Prolongation over time, macromolecule material
Material and additive all there will be degraded in various degree.Frame glue is also macromolecular material, and degradable component is easily added in frame glue.Frame
The very difficult instrument of trace impurity in glue detects, but the reliability of product is but had vital impact.
Two, the movement of piston is with CDA (compressed air) pressure as power, there will be piston position the most unavoidably
The situation of skew, causes stuck piston.Therefore in sebific duct, add black piston to use as short-term countermeasure, long-term production
Then need a kind of determination methods the most efficiently of design for processing procedure.
