Abstract
A roll stocker includes a plurality of roll fixing units for fixing a plurality of rubbing rolls; shaft connection parts having a plurality of radially extended end portions connected with each roll fixing unit; and a rotational shaft for fixing the center of the shaft connection parts and rotating the shaft connection parts. A plurality of rubbing rolls can be rotated, and by keeping the plurality of rubbing rolls in storage in the closed roll stocker, contamination of a rubbing cloth due to external particles can be prevented, space utilization can be enhanced, and deviation of eccentricity of the rubbing rolls kept in storage can be prevented.
Claims18
A method for fabricating an LCD device comprising:
- providing mother substrates each having a plurality of array substrates or a plurality of color filter substrates formed thereon;
- performing an array process on the array substrates and performing a color filter process on the color filter substrates;
- forming an alignment film on surfaces of the mother substrates;
- performing rubbing on the mother substrates with the alignment film formed thereon;
- taking out a required rubbing roll from a roll stocker, which includes a plurality of roll fixing units for fixing a plurality of rubbing rolls, a shaft connection part having a plurality of radially extended end portions connected with each roll fixing unit, a rotational shaft for fixing the center of the shaft connection part to rotating the shaft connection part, a driving unit for rotating the rotational shaft and a roll entrance for allowing a certain rubbing roll to be fed in and out therethrough so as to be kept in storage in the roll stocker or taken out of the roll stocker, as necessary, and continuously performing a rubbing process,
- wherein in order to take the required rubbing roll out of the roll stocker,
- rotating the rotational shaft so that the required rubbing roll to be positioned toward the roll entrance;
- pulling the pair of roll fixing units positioned at both ends of the rubbing roll to fix the rubbing roll in both outward directions;
- and
- taking the required rubbing roll out through the roll entrance;
- attaching the pair of rubbing process-finished mother substrates;
- and
- cutting the attached mother substrates into a plurality of unit liquid crystal display panels.
