Abstract

An alignment system includes: a light emitting device located on one side of an object to be aligned for emitting light towards the object to be aligned; a light receiving device located on the other side of the object to be aligned and at a standard position corresponding to an alignment mark disposed on the object to be aligned, the light receiving device being provided with a plurality of light sensors for sensing light emitting from the light emitting device on an end surface facing the object to be aligned; a processor configured to receive sensing signals transmitted from each of the light sensors and determine whether the object to be aligned is aligned accurately according to whether each of the light sensors sense the light emitted from the light emitting device. This alignment system shortens the processing time and enhances the processing efficiency.
