Abstract:
1. A parallelism measuring system, comprising: a measured module comprising a measured unit and an assisting unit, wherein a lower surface of the measured unit is a measured flat surface, an upper surface of the measured unit is attached to the assisting unit, and the assisting unit is used to adjust an inclination angle of the measured unit and to allow the measured unit to move upwards and downwards; a reference unit, wherein an upper surface of the reference unit is a flat reference surface used as a reference plane for parallelism measurement; and an optical measuring unit, wherein the optical measuring unit is used to measure parallelism of the measured surface and the reference surface, and comprises: wherein the light source unit is a laser, the sensing unit is a location aware device, the shift unit comprises a sliding rail structure and a servomotor, the sliding rail structure allows the supporting unit installed on the sliding rail structure to move along the sliding rail structure, and the servomotor to control the moving direction, speed and distance of the supporting unit installed on the sliding rail structure.
