[0002] During LCD panel production, edge micro-crack detection is required to identify edge defects caused by processes such as cutting and grinding. These defective panels need to be sorted out after inspection. Current technology typically involves manual sorting, where workers transfer defective LCD panels to a defective product unloading roller conveyor for unloading. However, manual transfer suffers from high labor intensity and low efficiency. Utility Model Content

Both the main gripping mechanism and the auxiliary gripping mechanism are used to grip the LCD panel; the auxiliary lifting mechanism is used to drive the auxiliary gripping mechanism to move back and forth in the vertical direction.

[0008] The beneficial effect of adopting the above-mentioned further solution is that by setting the main and auxiliary gripping mechanisms, multiple LCD panels can be gripped simultaneously, improving gripping efficiency; at the same time, by setting the auxiliary lifting mechanism, the gripping height of the auxiliary gripping mechanism can be adjusted by the auxiliary lifting mechanism, allowing the main and auxiliary gripping mechanisms to grip LCD panels of different heights respectively.

The suction port of the suction cup 22 is connected to the air pipe connector 25 through the central holes of the suction cup connecting rod 23 and the threaded rod 24, allowing air to be drawn from the suction port of the suction cup 22 through the air pipe connector 25, creating a negative pressure state within the suction port of the suction cup 22, thus enabling the suction cup 22 to suction the LCD panel through negative pressure. When installing and fixing the negative pressure suction cup mechanism, a through hole is opened in the suction mounting plate 15, the threaded rod 24 is inserted into the through hole, and two nuts are fitted on the threaded rod 24.
