Description
Technical field
The present invention relates to the manufacture field of liquid crystal display, a kind of method that relates in particular to liquid crystal panel sliver apparatus and use this device sliver.
Background technology
Liquid crystal display, or claim LCD(Liquid Crystal Display), being the display device of planar ultra-thin, it is comprised of colour or the monochrome pixels of some, is positioned over light source or reflecting surface the place ahead.The liquid crystal display power consumption is very low, and has high image quality, little, the lightweight characteristics of volume, and therefore extremely everybody favors, and becomes the main flow of display.
The main body of general liquid crystal display is liquid crystal cells, is mainly to consist of two transparency carriers and the liquid crystal that is enclosed between substrate.Liquid crystal display is with thin film transistor (TFT) (Thin Film Transistor at present, TFT) liquid crystal display is main, and the making of general Thin Film Transistor-LCD can roughly be divided into three parts: thin film transistor (TFT) array (TFT Array) preparation process and color filter preparation engineering, liquid crystal display assembling (LC Cell Assembly) preparation process, LCD MODULE (Liquid Crystal Module, LCM) preparation process.
In the process of liquid crystal panel, normally first the large panel of a monoblock is processed, and then large panel is cut into to needed undersized panel.In this process, mainly be divided into cutting and two steps of sliver: cutting is to use the break bar with certain degree of hardness, under certain pressure, streaks liquid crystal panel surface, thereby forms together dark cutting groove on its surface; Then carry out sliver technique, effective panel of the liquid crystal panel after making to cut separates with offal timber.
The sliver technique adopted at present comprises separating effective panel and offal timber.The mode that the separation of offal timber can be adopted offal timber folder gripping and deflect from, this method is comparatively stable because offal timber separates, and can reduce offal timber and the effectively scratch between panel, has reduced the loss of liquid crystal panel in sliver technique.But along with the development of liquid crystal panel to the large scale direction, the quantity of the offal timber adopted in sliver process folder can increase thereupon, like this, just can't guarantee the levelness between several offal timber folders, thereby therefore can increase circuit scratch probability, reduce yield rate.The another kind of mode that the sliver of offal timber adopts is to utilize roller to roll to assist sliver, as depicted in figs. 1 and 2, liquid crystal panel 100 after cutting comprises effective panel 110 and offal timber 120,200 pairs of the sliver unit offal timber 120 that employing is provided with a roller applies downward pressure, and along the opposite direction of cutting, namely the first end 120A along offal timber 120 rolls to the direction of the second end 120B.Offal timber 120, because the gravity that is subject to downward pressure and self drops naturally, causes the circuit scratch so be difficult for.Therefore utilizing roller to roll to assist sliver is the usual way of current large scale liquid crystal panel.
But, existingly utilize a roller to roll to assist the mode of sliver also to have certain problem.As shown in Figure 3, because what cutting was adopted at present is high infiltration flywheel knife, so offal timber can split very soon in the cutting rear section, and the liquid crystal panel 100 used at present is larger, cutter head is after cutting, splitting and hanging down easily appears in the offal timber of the second end 120B part, but does not break away from the phenomenon of effective panel 110 fully; When roller rolls, first end 120A along offal timber 120 rolls to the direction of the second end 120B due to roller, so when roller rolls in the position near first end 120A, the offal timber of first end 120A part drops downwards, may cause oppositely upspringing and getting to effective panel 110 near the second end 120B position sagging offal timber that split in advance, thereby the effective panel 110 of scratch, can improve the fraction defective of product, increases production cost.
Summary of the invention
