Measuring apparatus and controlling method thereof

摘要

The present disclosure provides a measuring apparatus including a platform, a measuring head movably arranged on the platform, pneumatic balls supporting the platform, an inflator, and a controlling device controlling the inflator to inflate the pneumatic balls while the measuring head is moving towards a next measuring point from a current measuring point. The controlling device controls the inflator to inflate the pneumatic balls with the required air inflation amount within the required time evenly during the movement of the measuring head, therefore, the vibration of the platform during the movement of the measuring head and the inflation of the pneumatic ball can be reduced, which can keep the platform horizontal quickly after the measuring head stops moving, reduce the measurement errors of the measuring head, further improve the productivity of the liquid crystal panel. The present disclosure further provides a controlling method of the above measuring apparatus.

主权项

1. A measuring apparatus, comprising:
a platform; a measuring head movably arranged on the platform; a plurality of pneumatic balls configured for supporting the platform; an inflator; and a controlling device configured for controlling the inflator to inflate a corresponding pneumatic ball while the measuring head is moving towards a next measuring point from a current measuring point;wherein the controlling device comprises an obtaining unit configured for obtaining an air inflation amount required to be inflated into the corresponding pneumatic ball after the measuring head moves to the next measuring point and obtaining a time required for the measuring head to move to the next measuring point from the current measuring point according to a moving speed of the measuring point and a distance between the current measuring point and the next measuring point.
