Description

Technical Field

[0001] The utility model relates to the technical field of palletizing, in particular to a palletizing device for packing liquid crystal display screens. Background Art

[0002] Liquid crystal displays (LCDs) are active-matrix displays driven by thin-film transistors. During the manufacturing process, LCDs often need to be stacked for storage and transportation. Traditional palletizing systems typically use suction cup jigs. One or more suction cups adhere to the surface of one or more boxes, and a palletizing robot drives the boxes to a predetermined position. However, when the box dimensions vary or when ventilation holes are located in the boxes corresponding to the suction cups, the suction cups of the suction cup jigs are less effective.

[0003] After searching, the patent with announcement number CN220466873U discloses a stacking device for LCD production, including a frame, and legs are fixedly connected to the front and back sides of the bottom of the frame. The patent uses the setting of a frame, a fixing component 1 and a fixing component 2 to cooperate with each other. The fixing component 1 fixes the frame and the protective plate to prevent the protective plate from being quickly replaced when damaged. The T-slot is located inside the circular groove 2. The U-shaped plate and the U-slot cooperate with each other. The shaft rod 3 is fixed and limited by the T-axis on the inner wall of the rectangular groove 1. The shaft rod 3 drives the U-shaped plates on both sides to swing left and right through the rotation connection with the T-axis. The U-slots on both sides of the U-shaped plate drive the shaft rod 4 to swing left and right. The U-shaped plate drives the shaft rod 5 to swing left and right. The swinging of the shaft rod 5 makes replacement more convenient and more stable. When the fixing component is damaged or the effect is not good after long-term use, it can be replaced through the fixing component.

[0004] However, the equipment disclosed in the above patent has poor flexibility and can only perform reciprocating stacking work. At the same time, it cannot be flexibly adjusted according to the size of the display box, resulting in significant limitations in its use. Therefore, the present application proposes a stacking device for packaging liquid crystal display screens. Utility Model Content

[0019] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the accompanying drawings in the embodiments of the present invention. Example

[0020] See also Figures 1-4 The present invention provides a technical solution: a palletizing device for packing liquid crystal display screens, comprising a base 1 and a mechanical arm 2. The mechanical arm 2 is fixedly installed on the top of the base 1. Under the action of the mechanical arm 2, the packaging boxes can be stacked on pallets at different positions, which is conducive to improving the flexibility of palletizing. It also includes a mounting frame 3, which is fixedly installed on the front end of the mechanical arm 2, and the bottom of the mounting frame 3 is fixedly connected to a frame 6. The side of the frame 6 away from the base 1 is fixedly connected to multiple first suction cups 7, which can adsorb the large side of the box to ensure the adsorption effect of the box. Two clamping plates 8 are symmetrically provided inside the mounting frame 3, and the sides of the two clamping plates 8 that are close to each other are fixedly connected to a second suction cup 9, which can adapt to packaging boxes of different specifications to ensure the stability of clamping. Two clamping assemblies 10 that drive the clamping plates 8 to move are symmetrically provided inside the mounting frame 3. A driving assembly 11 for driving the two clamping assemblies 10 to move is provided inside the mounting frame 3.

[0021] Furthermore, the driving assembly 11 includes a driving shaft 111, which rotates inside the mounting frame 3, and a driven synchronous pulley 112 is fixedly connected to the outside of the driving shaft 111, and a motor 113 is fixedly connected to the outside of the mounting frame 3. The output end of the motor 113 is fixedly connected to an automatic synchronous pulley 114, and a synchronous belt 115 is provided between the driven synchronous pulley 112 and the automatic synchronous pulley 114. The clamping assembly 10 includes a track 101, and the track 101 is symmetrically fixedly connected to the inside of the mounting frame 3, and a sliding block 102 is slidably provided on the track 101. A screw rod 103 is rotatably connected to the inside of the mounting frame 3, and one end of the screw rod 103 is connected to the driving shaft 111 through a coupling. The external thread of the screw rod 103 is connected to an internal threaded sleeve 104, and the internal threaded sleeve 104 is fixed to the sliding block 102;

[0022] Through the above structure, the two screw rods 103 can be driven at the same time, thereby driving the two clamping plates 8 and the second suction cup 9 to move synchronously toward the box body to achieve clamping on both sides of the box body, adapting to packaging boxes of different specifications while ensuring the stability of clamping.

[0023] Furthermore, a roller conveyor belt 4 is provided on one side of the machine base 1, and the roller conveyor belt 4 is located directly below the mounting frame 3, so as to facilitate the transportation of boxes that need to be stacked and facilitate stacking and material removal.

[0024] Furthermore, a protective fence 5 is provided on the outside of the machine base 1 and the roller conveyor belt 4 to protect the equipment and prevent accidents from occurring during operation.

[0025] In summary: the boxes to be stacked are placed vertically on the roller conveyor belt 4 and conveyed by the roller conveyor belt 4. When the boxes move to the bottom of the mounting frame 3, the mounting frame 3 is driven to move by the robotic arm 2, so that the first suction cup 7 on the frame 6 adsorbs the side wall of the box, and then the motor 113 is started. The motor 113 cooperates with the automatic synchronous pulley 114 and the synchronous belt 115 to drive the driven synchronous pulley 112 and the drive assembly 11 to rotate. At the same time, the drive shaft 111 drives the two screw rods 103 at both ends to rotate, and the screw rod 103 drives the driven synchronous pulley 112 and the drive assembly 11 to rotate. The movable internal threaded sleeve 104 moves outside it, and then the internal threaded sleeve 104 drives the sliding block 102 to slide on the track 101. Since the directions of the two screw rods 103 are opposite, the two sliding blocks 102 approach the box body synchronously, and drive the clamping plate 8 and the second suction cup 9 to move, so that the second suction cup 9 clamps the two side walls of the box body to ensure the stability of the adsorption and clamping of the box body during the stacking process. The box body is then stacked on the pallet by the robot arm 2, and the equipment can be protected by the outer protective fence 5 to prevent accidents during the operation.
