Description

Technical Field

[0001] This utility model relates to LCD product material sorting and arrangement equipment, and more particularly to an LCD liquid crystal display panel arrangement and conveying device. Background Technology

[0002] LCD panel raw materials are typically stacked in multiple layers. During the assembly process, LCD panels need to be laid flat one by one on a conveyor belt for subsequent robotic arms to pick up. For multi-layered LCD products, current technology generally involves vertical feeding, with the picking device picking up one LCD product from the top layer at a time. This method occupies a lot of vertical space. When a row of LCD products is picked up, the machine needs to be stopped and re-stacked, resulting in low work efficiency. At the same time, it leads to a large installation height and vertical travel of the picking device, which is not conducive to achieving precise motion control. In addition, due to factors such as gravity and static electricity, when the picking device picks up the top layer of LCD products, it is easy to pick up the second and third layers at the same time. This not only easily damages the LCD products, but also makes it difficult for the LCD products to be arranged one by one in the unloading mechanism. Therefore, it cannot meet the process requirements of high-precision conveying. Utility Model Content

[0003] The technical problem to be solved by this utility model is to provide an LCD display panel arrangement and conveying device that can achieve non-stop feeding, high working efficiency, and facilitates one-by-one material picking, in order to address the shortcomings of the existing technology.

[0004] To solve the above-mentioned technical problems, the present invention adopts the following technical solution.

[0005] An LCD panel arrangement and conveying device includes: a stacking conveying mechanism for conveying multiple LCD products, the multiple LCD products being upright and stacked sequentially; an arrangement conveying mechanism adjacent to the discharge end of the stacking conveying mechanism, the arrangement conveying mechanism being used to sequentially convey LCD products placed flat thereon; and a picking and handling mechanism disposed between the discharge end of the stacking conveying mechanism and the inlet end of the arrangement conveying mechanism, the moving end of the picking and handling mechanism being provided with a flipping arm, the flipping arm being provided with multiple suction nozzles, the picking and handling mechanism being used to: drive the flipping arm to move to the discharge end of the stacking conveying mechanism, control the multiple suction nozzles to pick up the LCD products stacked at the foremost end of the stacking conveying mechanism, then drive the flipping arm to move above the inlet end of the arrangement conveying mechanism, control the flipping arm to flip, and place the LCD products picked up by the multiple suction nozzles flat on the arrangement conveying mechanism.

[0006] Preferably, the system includes an organic platform, and the stacking conveyor, the picking and handling mechanism, and the arranging conveyor are all mounted on the platform.

[0007] Preferably, the stacking conveyor mechanism includes a double-row conveyor belt, a feeding drive mechanism for driving the double-row conveyor belt, and two limiting stops. Multiple LCD products are stacked sequentially on the double-row conveyor belt. The limiting stops extend along the conveying direction of the double-row conveyor belt, and the two limiting stops are respectively located on both sides of the double-row conveyor belt.

[0008] Preferably, the stacking conveyor mechanism includes a first support, the double-row conveyor belt and the limiting stop are both disposed on the first support, a front support block and a rear support block are fixed on the machine base, the height of the front support block is greater than the height of the rear support block, the first support is slidably connected to the top of the front support block and the rear support block, and the first support is tilted by the supporting action of the front support block and the rear support block.

[0009] Preferably, the material handling mechanism includes a gantry frame fixedly connected to the machine platform and a tilting arm motion mechanism disposed on the gantry frame, wherein the tilting arm is disposed at the moving end of the tilting arm motion mechanism.

[0010] Preferably, the flipping arm is an L-shaped arm, the vertical end of the flipping arm is fixedly connected to the rotating end of the flipping arm motion mechanism, and the horizontal end of the flipping arm is fixed with a plurality of parallel support rods, each support rod being provided with at least two suction nozzles.

Based on the sequential stacking method, the stacking conveying mechanism can drive multiple LCD products forward one by one.

At the same time, the picking and handling mechanism picks up the LCD products from the front side each time, which can avoid the influence of adverse factors such as the gravity or static electricity of the LCD products, and the picking accuracy and reliability are higher.

[0017] The present invention will now be described in more detail with reference to the accompanying drawings and embodiments.

[0018] This utility model discloses an LCD liquid crystal display panel arrangement and conveying device, combined with Figures 1 to 4 As shown, it includes:

[0019] The stacking conveyor 1 is used to convey multiple LCD products 100, which are arranged upright and stacked sequentially.

[0020] The arranging conveyor 3 is arranged adjacent to the discharge end of the stacking conveyor 1. The arranging conveyor 3 is used to sequentially convey LCD products 100 placed flat on it.

[0021] The material handling mechanism 2 is located between the discharge end of the stacking conveying mechanism 1 and the inlet end of the arranging conveying mechanism 3. The moving end of the material handling mechanism 2 is equipped with a tilting arm 20, which has multiple suction nozzles 21. The material handling mechanism 2 is used for:

[0022] The flipping arm 20 is driven to move to the discharge end of the stacking conveyor mechanism 1, and multiple suction nozzles 21 are controlled to pick up the LCD product 100 stacked at the front end of the stacking conveyor mechanism 1. Then, the flipping arm 20 is driven to move above the inlet end of the arrangement conveyor mechanism 3, and the flipping arm 20 is controlled to flip, and the LCD product 100 picked up by the multiple suction nozzles 21 is placed flat on the arrangement conveyor mechanism 3.

[0023] In the above structure, during loading, multiple LCD products 100 stacked sequentially are placed horizontally on the stacking conveyor 1. Based on the sequential stacking method, the stacking conveyor 1 can drive multiple LCD products 100 forward one by one. During material retrieval, the material retrieval and handling mechanism 2 first moves the flipping arm 20 to the discharge end of the stacking conveyor 1, then controls multiple suction nozzles 21 to pick up the LCD product 100 stacked at the front end of the stacking conveyor 1, then drives the flipping arm 20 to move above the inlet end of the arranging conveyor 3, and finally controls the flipping arm 20 to flip, thereby placing the LCD product 100 picked up by the multiple suction nozzles 21 flat on the arranging conveyor 3. Compared with the prior art, in the process of the stacking conveyor 1 conveying multiple LCD products 100 forward, when the LCD product 100 is about to be picked up, multiple LCD products 100 can be directly added to the rear side. The replenishment process does not require stopping the machine, which can ensure the continuous and efficient operation of the equipment. At the same time, the picking and handling mechanism 2 picks up the LCD product 100 from the front side each time, which can avoid the influence of adverse factors such as the gravity or static electricity of the LCD product, and the picking accuracy and reliability are higher.

[0024] For its load-bearing function, please refer to Figure 1 This embodiment includes an organic platform 4, on which the stacking conveying mechanism 1, the picking and handling mechanism 2, and the arranging conveying mechanism 3 are all mounted.

[0025] As a preferred method, please refer to Figure 1 and Figure 2 The stacking conveyor mechanism 1 includes a double-row conveyor belt 10, a feeding drive mechanism 11 for driving the double-row conveyor belt 10 to operate, and two limiting rods 12. Multiple LCD products 100 are stacked sequentially on the double-row conveyor belt 10. The limiting rods 12 extend along the conveying direction of the double-row conveyor belt 10, and the two limiting rods 12 are respectively located on both sides of the double-row conveyor belt 10.

[0026] In the above structure, a double-row conveyor belt 10 is used to transport multiple stacked LCD products 100. The double-row conveyor belt 10 can avoid excessive contact with the sides of the LCD products 100, thereby preventing the sides of the LCD products 100 from cracking or being damaged by force. The limiting stop bar 12 mainly serves to limit and block the LCD products 100 from the side.

[0027] Based on this, please see Figure 2 and Figure 3 The stacking conveying mechanism 1 includes a first support 13. The double-row conveyor belt 10 and the limiting stop bar 12 are both mounted on the first support 13. A front support block 40 and a rear support block 41 are fixed on the machine base 4. The height of the front support block 40 is greater than the height of the rear support block 41. The first support 13 is slidably connected to the top of the front support block 40 and the rear support block 41. The support of the front support block 40 and the rear support block 41 causes the first support 13 to tilt. Because the top height of the front support block 40 is higher than the top height of the rear support block 41, the front end of the first support 13 can be raised. The front ends of the multiple LCD products 100 stacked sequentially are slightly tilted upwards. This posture can prevent the front LCD products 100 from tipping over and helps the material handling mechanism 2 to accurately pick up the materials.

[0028] For a preferred structure of the material handling mechanism 2, please refer to [link / reference]. Figure 2 The material handling mechanism 2 includes a gantry frame 22 fixedly connected to the machine base 4 and a tilting arm motion mechanism 23 mounted on the gantry frame 22. The tilting arm 20 is located at the moving end of the tilting arm motion mechanism 23. The tilting arm motion mechanism 23 may be composed of a linear motion module, a rotary cylinder, or other mechanisms.

[0029] Furthermore, the tilting arm 20 is an L-shaped arm. The vertical end of the tilting arm 20 is fixedly connected to the rotating end of the tilting arm motion mechanism 23. The horizontal end of the tilting arm 20 is fixed with multiple parallel support rods 24, each support rod 24 having at least two suction nozzles 21. The L-shaped tilting arm 20 allows the suction nozzles 21 to extend outward relative to the tilting arm motion mechanism 23, preventing positional interference between the tilting arm 20 and the tilting arm motion mechanism 23. In addition, each support rod 24 can be provided with a negative pressure suction hole communicating with the suction nozzle 21 to facilitate connection to a negative pressure air source.

[0030] For a preferred structure of the arrangement and conveying mechanism 3, please refer to [link / reference]. Figure 4The arrangement and conveying mechanism 3 includes a base plate 30, which is fixedly connected to the machine base 4. The base plate 30 is provided with two parallel slide rails 31 that extend in the left and right directions. The two slide rails 31 are provided with slide tables 32. The slide tables 32 are provided with a feeding conveyor belt 33. The feeding end of the feeding conveyor belt 33 is located below the tilting arm 20. The machine base 4 is provided with a feeding drive mechanism 34 for driving the feeding conveyor belt 33 to operate.

[0031] In the above structure, by setting two slide rails 31 and the slide table 32, the left and right positions of the unloading conveyor belt 33 can be easily adjusted, so as to better match the unloading position of the material handling mechanism 2.

[0032] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. All modifications, equivalent substitutions or improvements made within the technical scope of the present utility model should be included within the scope of protection of the present utility model.
