[0075] In addition, the mounting plate 211 in the embodiment further comprises a seventh driving member 2113, the seventh driving member 2113 is configured to drive the second clamping module 230 to move along the vertical direction, and when the second clamping module 230 moves to the grinding jig, the seventh driving member 2113 drives the second clamping module 230 to move along the vertical direction instead of the mechanical hand 210, so as to ensure that the pressing block 150 clamped by the second clamping module 230 can be accurately overlaid above the glass sheet, so as to avoid that the pressing block 150 clamped by the second clamping module 230 shakes along the horizontal direction and is not overlaid above the glass sheet according to the preset path, thereby avoiding that the pressing block 150 collides with the glass sheet to cause damage to the glass sheet.

[0076] It can be understood that the seventh driving member 2113 can be a linear driving structure such as a pneumatic cylinder or an electric cylinder, which is not specifically limited in the embodiment.

[0077] After the grinding is completed, the second clamping module 230 needs to take the pressing block 150 away from the first carrier 110, in order to avoid that the pressing block 150 sticks to the glass sheet below when the second clamping module 230 takes the pressing block 150, the second clamping module 230 in the embodiment further comprises a spring plunger 234, the spring plunger 234 can press against the glass sheet above when the second clamping module 230 clamps the pressing block 150 from the grinding jig, so as to separate the pressing block 150 and the glass sheet below when the second clamping module 230 takes away the pressing block 150.
