However, the first side push rod, the second side push rod, the first end push rod, and the second end push rod respectively require a first driving mechanism, a second driving mechanism, a third driving mechanism, and a fourth driving mechanism for driving, which not only results in a complex overall structure, large volume, and high manufacturing cost, but also can only calibrate one liquid crystal glass substrate at a time, with low calibration efficiency.

[0038] Furthermore, a sensor 6 is provided in the correction station 3 and is staggered with the vacuum adsorption groove to detect whether there is material discharge, so as to avoid misoperation.
