S3: after the etching of the liquid crystal glass is finished, the spray nozzle 466 is closed, then the telescopic air cylinders 22 drive the lower pressure plate 23 and the suction disc 25 to move downwards, so that the suction disc 25 adsorbs and fixes the etched liquid crystal glass, then any one telescopic air cylinder 22 drives the liquid crystal glass to move upwards through the lower pressure plate 23 and the suction disc 25, so that the liquid crystal glass is in an inclined state, the residual etching agent and reactants at the upper end of the liquid crystal glass are poured into the discharge hopper 42, then the lower pressure plate 23 and the liquid crystal glass are restored to a horizontal state through the telescopic air cylinders 22 and then move upwards, at the moment, the liquid crystal glass is positioned below the bearing plate 274, and then the etched liquid crystal glass is taken down from the lower end of the suction disc 25.
The above description is only of the preferred embodiments of the present invention and is not intended to limit the present invention, but various modifications and variations can be made to the present invention by those skilled in the art. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
