Further, as shown in fig. 6 and 7, the positioning driving member 1311 is a linear driving module, the linear driving modules of the side positioning assemblies 131 in the first direction are disposed in parallel on the cross beam 1321, and the linear driving modules of the side positioning assemblies 131 in the second direction are disposed in parallel on the longitudinal beam 1322. Alternatively, the positioning driver 1311 may be a linear driving cylinder, which is arranged in the same manner as the linear driving module.

In another embodiment of the present invention, as shown in FIG. 7, the positioning member 1312 is a roller member rotatably mounted on the output shaft of the positioning driving member 1311, and the roller axis of the roller member is perpendicular to the glass conveying plane 112.
