Description
[technical field]
The present invention is a kind of single-piece type pressurized deairing device, and it is especially in regard to a kind of loophole that in light shielding part, is provided with, and frame glue is located in the loophole, with promote frame glue and colored filter substrate contact area single-piece type pressurized deairing device.
[background technology]
Please with reference to Fig. 1; Polaroid 2 is positioned on the polaroid substrate; Wherein the attaching face 3 of polaroid 2 is that vacuum attaches face, colored filter substrate and the thin film transistor base plate of liquid crystal panel 6 for having fitted in the processing procedure, utilize mechanical arm 4 that liquid crystal panel 6 is carried to attaching place after; Polaroid 2 is attached to one of colored filter substrate or thin film transistor base plate of liquid crystal panel 6 with the vacuum suction mode; And with cylinder 8 polaroid 2 is flattened, often, be difficult to reach abswolute level (promptly round inadequately) because of out of roundness of cylinder 8 (Roller) itself; And (the pressure sensitive adhesives of the pressure-sensing glue on polaroid 2; PSA) have the situation generation of starved among a small circle unavoidably, so often there are trickle minute bubbles 10 to result between polaroid and colored filter substrate (or thin film transistor base plate), the mode that prior art solves these minute bubbles 10 is these minute bubbles to be removed (removing: reach visual invisible degree) with the intensification pressing mode.
The present solution of prior art is to realize the removal of micro-bubble through pressure defoaming machine 12 warming and pressurizing.Prior art adopts the mode of heating, and mainly polaroid 2 is attached the pressure-sensing glue softening (helping " breaing up " bubble) of face.The purpose of pressurization then is that the minute bubbles that these are trickle " are broken up " (dissolving), and is attached at the surface of colored filter substrate or thin film transistor base plate more closely, and PSA itself when being under pressure viscosity also can strengthen thereupon.Please in the lump with reference to Fig. 2; Fig. 2 prior art is removed the structural scheme of mechanism of these minute bubbles; Prior art provides an airtight cell body 14, and still having heaters 16 and backflow fan 18 in cell body 14 utilize heater 16 and backflow fan 18 to keep cell bodies 14 to keep even temperature.When the such equipment of practical operation, need the thing to be processed 19 (problematic panel) of accumulation some earlier, once send in the cell body 14 and handle, handle a collection of problematic panel end half an hour approximately.After when the lazy weight of the panel of problem, must waiting until certain quantity, just can send in the cell body 14 and process.This is for get rather inconvenience in the production process in reality.
At first this pressure defoaming machine 12 often can not be arranged near the Polarizer chip mounter, no matter is to be sent to pressure defoaming machine 12 automatically with manpower or machine, all needs extra time cost.Moreover, must accumulate and just can handle after some has the problem panel, more difficult in the control of time cost for manufacturer.
