The conveyor belt 3 is installed between the drive base 1 and the mounting base 2. A rodless cylinder 4 is embedded and fixedly fixed on the top of the drive base 1. The movable end of the rodless cylinder 4 is fixedly connected to a mounting support column 5. An L-shaped support plate 6 is connected to the right side of the mounting support column 5. A first telescopic cylinder 7 is fixedly connected to the top of the L-shaped support plate 6. The first telescopic cylinder 7 penetrates the inner side of the L-shaped support plate 6 and is fixedly connected to a laser cutter 8. A material handling mechanism 9 is connected to the top of the mounting base 2. The mounting support column 5 includes a moving... The movable column 10 and the mounting column 11 are fixedly connected at the middle right side of the movable column 10 and the mounting column 11. A first servo motor 12 is fixedly connected to the front side of the mounting column 11. A second telescopic cylinder 13 is fixedly connected to the lower front side of the movable column 10.

A guide rod 16 is provided on one side of the lead screw 15. A movable block 17 is sleeved on the outer side of the lead screw 15 and the guide rod 16. The output shaft of the first servo motor 12 is fixedly connected to the front end of the lead screw 15. The right side of the movable block 17 is connected to the mounting column 11. The L-shaped support plate 6 is fixedly connected. A lead screw nut is installed inside the moving block 17 via a bearing, and the lead screw nut is threadedly connected to the lead screw 15. The fixed end of the second telescopic cylinder 13 passes through the rear side of the moving column 10, and the movable end is fixedly connected to a pusher plate 18. By activating the conveyor belt 3 and the second telescopic cylinder 13, the conveyor belt 3 can move the liquid crystal glass laterally between the drive seat 1 and the mounting seat 2. The movable end of the second telescopic cylinder 13 drives the pusher plate 18 to push and guide the liquid crystal glass on the conveyor belt 3, preventing it from being transported... If belt 3 deviates during the conveying process, the first servo motor 12 is started. The output shaft of the first servo motor 12 drives the lead screw 15 to rotate. Under the guidance and limiting action of the guide rod 16 on the moving block 17, the lead screw 15 and the moving block 17 on the outside of the guide rod 16 can drive the laser cutting machine 8 to make lateral adjustments. The second telescopic cylinder 13 drives the laser cutting machine 8 to make vertical lifting adjustments, and the rodless cylinder 4 drives the moving column 10 to make lateral displacement, which can more accurately cut the fed liquid crystal glass.

[0025] Preferably, the material handling mechanism 9 includes a rotating shaft 19 and a connecting block 20.

Flip-turn plates 22 are equidistantly sleeved and fixed on the outer wall of the rotating shaft 19. Rubber suction cups 23 are equidistantly connected to the front side of the flip-turn plates 22. By starting the second servo motor 21, the output shaft of the second servo motor 21 drives the rotating shaft 19 to rotate, so that the flip-turn plates 22 on the outer wall of the rotating shaft 19 are adjusted forward, so that the rubber suction cups 23 on the bottom side of the flip-turn plates 22 press against the surface of the cut liquid crystal glass. Then, the second servo motor 21 is controlled again to drive the rotating shaft 19 to rotate backward to a horizontal state, which can quickly and timely handle the cut liquid crystal glass.

A vacuum suction cup 28 is fixedly connected through the top side of the inner wall of the rubber suction cup 23. The rear end interface of the vacuum suction cup 28 is connected to the T-shaped pipe 27 through a solenoid valve. The T-shaped pipe 27 is connected to an external vacuum generator, so that the front of the T-shaped pipe 27... The vacuum suction cup 28 on the side, together with the rubber suction cup 23, adsorbs and fixes the cut liquid crystal glass. Then, the material picking mechanism 9 can stably adsorb and pick up the cut liquid crystal glass. New liquid crystal glass can be placed on the rubber suction cup 23, and the vacuum suction cup 28 adsorbs and fixes the new liquid crystal glass. Then, the material picking mechanism 9 flips the new liquid crystal glass and places it on the conveyor belt 3. The entire feeding and picking operation does not require the staff to manually contact the liquid crystal glass for a long time, avoiding fingerprints and stains left on the surface of the liquid crystal glass, and further improving its practicality.

[0027] In summary, with the help of the above-mentioned technical solution of this utility model, when this device is in use, by activating the conveyor belt 3 and the second telescopic cylinder 13, the conveyor belt 3 can move the liquid crystal glass laterally between the drive seat 1 and the mounting seat 2. The movable end of the second telescopic cylinder 13 drives the pusher plate 18 to push and guide the liquid crystal glass on the conveyor belt 3, preventing the conveyor belt 3 from deviating during the conveying process. By activating the first servo motor 12, the output shaft of the first servo motor 12 drives the lead screw 15 to rotate. Under the guidance and limiting action of the guide rod 16 on the moving block 17, the lead screw 15 and the moving block 17 outside the guide rod 16 can drive the laser cutting machine 8 to perform lateral adjustment. The second telescopic cylinder 13 drives the laser cutting machine 8 to perform vertical lifting adjustment, and the rodless cylinder 4 drives the moving column 10 to perform lateral displacement. By starting the second servo motor 21, the output shaft of the second servo motor 21 drives the rotating shaft 19 to rotate, causing the flip-turn plate 22 on the outer wall of the rotating shaft 19 to be adjusted forward, so that the rubber suction cup 23 on the bottom side of the flip-turn plate 22 presses against the surface of the cut liquid crystal glass. Then, the second servo motor 21 is controlled again to drive the rotating shaft 19 to rotate backward to a horizontal state. The T-shaped pipe 27 is connected to an external vacuum generator, so that the vacuum suction cup 28 on the front side of the T-shaped pipe 27 cooperates with the rubber suction cup 23 to adsorb and fix the cut liquid crystal glass. Then, the material picking mechanism 9 can stably adsorb and pick up the cut liquid crystal glass, and place the new liquid crystal glass on the rubber suction cup 23. The vacuum suction cup 28 adsorbs and fixes the new liquid crystal glass, and then the material picking mechanism 9 flips and places the new liquid crystal glass on the conveyor belt 3.
