Description
Technical field
The present invention relates to display device manufacturing technology field, particularly relate to a kind of friction cloth stripping off device and friction cloth stripping means.
Background technology
The agent structure of liquid crystal indicator comprises box color membrane substrates together and array base palte, and is filled in liquid crystal molecule therebetween.Liquid crystal indicator is in original state, and state when namely not applying voltage to liquid crystal indicator, the liquid crystal molecule of its inside has same pretilt angle, presents even, consistent arrangement.For making liquid crystal molecule have identical tilt angle in original state, usually can arrange alignment films on the relative surface of color membrane substrates with array base palte, the surface of alignment films is formed with the groove with certain orientation, to produce grappling effect to liquid crystal molecule.At present, alignment films is formed groove and mainly adopts friction process, namely on friction roller, paste friction cloth, utilize friction cloth to rub in alignment films, form groove.
In actual production, different products may need to adopt different alignment film material to form alignment film, and different alignment film material needs again to mate different friction cloth, at this moment just needs friction cloth to be stripped down from friction roller, to change friction cloth.The method of usual stripping friction cloth is: utilize glutinous cloth rewinder roll to be pasted on the surface of friction cloth by pasting film, then utilize glutinous cloth rewinder roll from the end of friction cloth, peel off this and paste film, pasting film by peeling off this, peeling off pasting with this friction cloth that film is pasted together from friction roller.
But, be pasted onto in the Long-Time Service process on friction roller in friction cloth, friction cloth can more and more firmly be pasted onto on friction roller, causes when film is pasted in stripping, pastes the viscous force of film to friction cloth and is not enough to make to paste peeling off from friction roller of film and friction cloth one.And, because the friction cloth be pasted on friction roller cuts off from the friction cloth of reel and comes, therefore the end being pasted on the friction cloth on friction roller is the section tilted, this causes pasting the end that film is difficult to be close to friction cloth, thus paste film and cannot apply stronger viscous force to the end of friction cloth, and then also just cannot peel off from the end of friction cloth.
And if by improving the mode of pressing force, will film be pasted firmly be close to the end of friction cloth especially friction cloth, although more effectively can peel off friction cloth, improving pressing force can cause damage to friction roller.
