ALIGNMENT APPARATUS

摘要

An alignment apparatus includes a base, an alignment roller and a mounting frame, the alignment roller being attached with an alignment rubbing-cloth, the mounting frame having two mounting portions for mounting one of two ends of alignment roller, respectively. The alignment apparatus further includes: at least one laser emitting unit disposed on a mounting portion where one end of alignment roller is located, light rays emitted from each laser emitting unit being distant from axis of alignment roller by preset distance; at least one laser blocking unit corresponding to at least one laser emitting unit, respectively, and disposed on a mounting portion where the other end of alignment roller is located; a controller in a signal connection with each laser emitting unit and configured for controlling a part or all of the laser emitting units to be activated while alignment roller is performing rubbing alignment on a surface of the substrate.

1. An alignment apparatus, comprising a base, an alignment roller and a mounting frame for pivotally mounting the alignment roller, the base having a supporting surface for supporting a substrate, the alignment roller being attached with an alignment rubbing-cloth, the mounting frame having two mounting portions which are used for mounting two ends of the alignment roller, respectively, wherein the alignment apparatus further comprises:
at least one laser emitting unit which is disposed on the mounting portion where one end of two ends of the alignment roller is located, light rays emitted from each laser emitting unit being distant from an axis of the alignment roller by a preset distance; at least one laser blocking unit which corresponds to the at least one laser emitting unit, respectively, and is disposed on the mounting portion where the other end of two ends of the alignment roller is located; and a controller which is in a signal connection with each laser emitting unit and is configured for controlling a part or all of the laser emitting units to be activated while the alignment roller is performing a rubbing alignment on a surface of the substrate.
