The driving block 2086 and the limit seat 2081 are both rectangular in design, and the front limit opening 202 and the rear limit opening 204 are both rectangular in design. The plate removal robot 208 includes a mounting frame 20810, and a mounting area 2088 is provided inside the mounting frame 20810. At the same time, a gear 2087 is movably installed inside the mounting frame 20810.

[0034] Specific implementation seven: This implementation is a further limitation of specific implementation six. A drive motor 2089 is fixedly installed on the side wall of the installation frame 20810, and the output shaft of the drive motor 2089 is fixedly connected to the rotating shaft of the gear 2087. At the same time, a drive frame 2084 is movably installed on the left side of the interior of the installation frame 20810.

[0035] Specific embodiment eight: This embodiment is a further limitation of specific embodiment seven, a rack 2085 is fixedly mounted on the right side surface of the driving frame 2084, and the rack 2085 is adapted to the size of the gear 2087, and the rack 2085 is meshingly connected with the gear 2087, the interior of the driving frame 2084 is hollow, a guide seat 2083 is fixedly mounted on the left side surface of the driving frame 2084, and the guide seat 2083 is slidably mounted in a guide groove opened in the guide rail 2082, and the cross-sections of the guide seat 2083 and the guide groove are both dovetail-shaped.

[0036] Specific implementation nine: This implementation is a further limitation of specific implementation eight, wherein the driving frame 2084 is driven to rise and fall inside the mounting frame 20810 by a driving motor 2089, a gear 2087 and a rack 2085, and a sampling frame 20812 is fixedly mounted on the bottom of the driving frame 2084, and five rows of mounting plates 20813 are evenly mounted on the bottom of the sampling frame 20812, and a plurality of groups of vacuum suction cups 20814 are evenly mounted on the bottom of the five rows of mounting plates 20813.

[0037] The working mode of the first plate-taking robot 200 is as follows: when the glass needs to be transported, the sampling frame 20812 moves downward, so that the multiple groups of mounting plates 20813 at the bottom of the sampling frame 20812 move downward, and are pressed down on the upper surface of the glass by the vacuum suction cups 20814, so that the glass is positively adsorbed by the sampling frame 20812.
