The roller conveyor line 11 is used for unloading empty pallets; the belt conveyor line 12 is used for loading full pallets. A first lifting mechanism 13 is arranged between the roller conveyor line 11 and the belt conveyor line 12, which is used to transport the empty pallet that has been picked up from the belt conveyor line 12 to the roller conveyor line 11.

[0032] Preferably, in a liquid crystal panel handling device of this embodiment, the first lifting mechanism 13 includes a screw-nut driving mechanism vertically mounted on the frame 10, and an action output end of the screw-nut driving mechanism is fixedly connected to a bracket for lifting the tray.

[0033] Preferably, in a liquid crystal panel handling device of the present embodiment, the panel handling module 30 is arranged above the tray conveying mechanism 20, and the panel handling module 30 includes a first horizontal module arranged in the horizontal direction and a vertical module connected to the action output part of the first horizontal module, and the action output part of the vertical module is connected to the second panel suction cup mechanism 31. The second panel suction cup mechanism 31 includes a second mounting frame 32, and the second mounting frame 32 is provided with four second waist holes distributed along its diagonal direction, and the second suction cup brackets 33 are slidably installed in the four second waist holes. The second mounting frame 32 is also provided with a first driving cylinder 34, and the telescopic rod of the first driving cylinder 34 is connected to the second suction cup bracket 33, which is used to drive the second suction cup bracket 33 to slide in the second waist hole.

[0034] Preferably, in the liquid crystal panel handling device of the present embodiment, a height-adjustable limit block is provided at the bottom of the second mounting frame 32 to prevent the liquid crystal panel from being excessively squeezed when the vacuum suction cup adsorbs the liquid crystal panel.

[0035] Preferably, in a liquid crystal panel handling device of the present embodiment, a handling robot 40 is arranged at the unloading end of the frame 10, and its action output end is connected to a first panel suction cup mechanism 41.

[0036] It should be noted that, compared with the second panel suction cup mechanism 31, the first panel suction cup mechanism 41 is provided with more suction cups, because the first panel suction cup mechanism 41 needs to move along with the multi-axis of the transport robot 40 and requires a stable adsorption connection.

[0037] The roller conveyor line 11 includes a split roller conveyor line near the first lifting mechanism 13 and an integral roller conveyor line away from the first lifting mechanism 13.

[0038] Specifically, the split roller conveyor line is configured as two roller lines distributed on both sides of the lifting bracket. During actual operation, the lifting bracket of the first lifting mechanism 13 moves the empty pallet on the belt conveyor line 12 downward to the split roller conveyor line, and the lifting bracket continues to move downward and separates from the empty pallet. The split roller conveyor line moves the empty pallet to the integrated roller conveyor line for delivery.

[0039] A second lifting mechanism 14 is provided at one end of the belt conveyor line 12 away from the first lifting mechanism 13. The second lifting mechanism 14 includes slide plates that are horizontally slidably arranged on both sides of the belt conveyor line 12, and the moving direction of the slide plates is perpendicular to the running direction of the belt conveyor line 12. The two slide plates are driven by the screw nut to slide in opposite directions to adjust the spacing. A vertical lifting module is provided on the slide plate, and a clamping mechanism 15 for clamping the side of the bracket is fixedly connected to the action output end of the lifting module. By controlling the horizontal sliding of the slide plate and the lifting and lowering of the lifting module, the clamping mechanism 15 can accurately clamp and lift the fully loaded pallet, and transport it from the previous workstation at a high place to the loading end of the belt conveyor line 12.

When working, the two second driving cylinders are extended and retracted simultaneously to drive the hook claws to clamp or release the pallet.

[0041] On both sides of the end of the belt conveyor line 12 close to the first lifting mechanism 13, a second horizontal module parallel to the slide is slidably arranged, and the second horizontal module is horizontally slidably arranged on the table of the frame through a screw nut driving mechanism and a guide rail slider, and the sliding direction of the second horizontal module is perpendicular to the moving direction of its action output part. The action output parts of the two second horizontal modules are also respectively provided with a clamping mechanism 15, which is used to clamp the side of the bracket before the pallet is transported to the first lifting mechanism 13. A limited stop mechanism is arranged under the second horizontal module, including a lifting cylinder and a stopper connected to the lifting cylinder. When the fully loaded pallet moves to the feeding end of the second horizontal module, the lifting block of the lifting cylinder limits the fully loaded pallet, which is convenient for the panel handling module 30 to adsorb and handle the panel.

[0043] The working process of the utility model is as follows: first, the fully loaded pallet from the previous station is transported to the loading station of the second lifting mechanism 14, and the clamping mechanism 15 clamps the fully loaded pallet. Driven by the lifting module, the fully loaded pallet is placed on the belt conveyor line 12 below, and moves to the material picking station with the belt conveyor line. The clamping mechanism 15 where the second horizontal module is located clamps the fully loaded pallet, and the second panel suction cup mechanism 31 on the panel handling module 30 adsorbs the panel and transports it to the panel pallet 16. The first linear electric cylinder and the second linear electric cylinder drive the panel pallet 16 to move to the unloading station, and then the handling robot 40 drives the first panel suction cup mechanism 41 to adsorb the panel on the panel pallet 16 and transport it to the production loading station.

[0044] After the panel on the fully loaded pallet is taken away, the second horizontal module drives the empty pallet to move to above the lifting bracket of the first lifting mechanism 13, the lifting bracket rises and contacts the bottom of the empty pallet, the clamping mechanism 15 where the second horizontal module is located releases the empty pallet and moves to its original position, the lifting bracket moves downward to place the empty pallet on the split roller conveyor line, and is sent out along the integrated roller conveyor line.
