Description
Technical Field

[0002] With the continuous development of electronic technology, TFT-LCD (Liquid Crystal Display) is widely used in various electronic products. High-generation substrates refer to larger glass substrates, usually referring to products from 8.5-generation lines and above. High-generation substrates are the core components of LCD panels. The larger the size of the substrate, the more small LCD panels can be cut, thereby reducing the cost per unit area. In the LCD glass substrate production process, the precision cutting process mainly involves cutting the long and short sides of the substrate. After the LCD glass substrate is cut and scribed, it is then broken to obtain LCD glass substrates of specific specifications. When cutting and scribing the glass, a cutting blade is usually used. However, in actual use, the cutting blade is directly exposed to the outside without a corresponding protective structure, and therefore the cutting blade is easily damaged by impacts from external objects.

[0017] Reference Figures 1 to 4 As shown, this utility model provides a high-generation substrate edge cutting device, including: a main fixing plate 2 and a guide assembly 4. The upper surface of the main fixing plate 2 is fixedly connected to a main motor 1, the lower surface of the main fixing plate 2 is fixedly connected to a secondary fixing plate 3, and the inner side of the secondary fixing plate 3 is fixedly connected to a reinforcing plate 19. The output shaft of the main motor 1 is movably connected to the reinforcing plate 19 through a bearing, and the lower surface of the secondary fixing plate 3 is fixedly connected to a servo cylinder 12 through a fixing frame 11. The telescopic rod of the servo cylinder 12 is fixedly connected to a moving plate 15 through a pressure sensor 14, and the lower surface of the moving plate 15 is fixedly connected to a cutting blade 17 through a groove. At the same time, symmetrical openings are made on both sides of the moving plate 15. A buffer groove is provided, in which a buffer block is slidably connected. The buffer block is fixedly connected to a side buffer plate 18. The two ends of the side buffer plate 18 are symmetrically connected to end buffer plates 16. The guide assembly 4 consists of a vertical plate 7, a main horizontal plate 6, a secondary horizontal plate 8, and a guide rod 9. The main horizontal plate 6, the secondary horizontal plate 8, and the guide rod 9 are fixedly connected to the surface of the vertical plate 7. The upper surface of the main horizontal plate 6 is fixedly connected to a guide plate 5. The lower surface of the main fixed plate 2 is connected to the main slide plate 20 relative to the guide plate 5. At the same time, a rack is fixedly connected to the side of the secondary horizontal plate 8. The rack meshes with the drive wheel connected to the output shaft of the main motor 1. The secondary fixed plate 3 has a guide hole corresponding to the position of the guide rod 9.
[0018] In this embodiment, when the liquid crystal glass substrate needs to be cut and scribed, the servo cylinder 12 is first activated by an external PLC component (not shown in the figure). The extension rod of the servo cylinder 12 pushes the moving plate 15 downward through the pressure sensor 14. The moving plate 15 can drive the cutting blade 17, the side buffer plate 18, and the end buffer plate 16 to move synchronously. The side buffer plate 18 and the end buffer plate 16 contact the surface of the liquid crystal glass substrate before the cutting blade 17. Therefore, during the subsequent downward movement of the moving plate 15 and the cutting blade 17, the side buffer plate 18 and the end buffer plate 16 generate relative movement with the moving plate 15, so that the cutting blade 17 can smoothly abut against the surface of the liquid crystal glass substrate. The pressure sensor 14 can transmit the pressure data of the cutting blade 17 to the electrically connected PLC component in real time to ensure that the cutting blade 17 makes real contact with the surface of the liquid crystal glass substrate. When the cutting pressure is within a suitable range, the main motor 1 is started by the PLC component. The output shaft of the main motor 1 drives the drive wheel to rotate at a low speed. The drive wheel, through the meshing rack, can drive the main fixing plate 2, the auxiliary fixing plate 3, the main motor 1, the servo cylinder 12, the moving plate 15, and the cutting blade 17 to move in the horizontal plane, thereby realizing the cutting blade 17 to cut and scribing on the surface of the liquid crystal glass substrate. When the cutting and scribing of the liquid crystal glass substrate is completed, the PLC component will control the servo cylinder 12 to reset, which will cause the cutting blade 17, the side buffer plate 18, and the end buffer plate 16 to detach from the surface of the liquid crystal glass substrate. This can prevent the cutting blade 17 from falling over on the surface of the liquid crystal glass substrate and ensure the quality of the cutting line. The side buffer plate 18 and the end buffer plate 16 can fall naturally under the action of gravity, thereby enhancing the protection effect on the cutting blade 17.
[0019] In a preferred embodiment, the main fixing plate 2 has a rectangular structure, and through holes are opened on the surface of the main fixing plate 2 corresponding to the position of the output shaft of the main motor 1. The auxiliary fixing plate 3, which is fixedly connected to the main fixing plate 2, has an L-shaped structure, and the guide hole opened at the end of the auxiliary fixing plate 3 away from the main fixing plate 2 is adapted to the size of the guide rod 9.
[0020] In this embodiment, if Figure 1 and Figure 2 The main fixing plate 2 and the secondary fixing plate 3 enable the cutting device to move stably in the horizontal direction via the guide assembly 4, thereby enhancing the cutting quality of the liquid crystal glass substrate.
[0021] In a preferred embodiment, the reinforcing plate 19 fixedly connected to the surface of the secondary fixing plate 3 has a rectangular structure. The end of the reinforcing plate 19 away from the secondary fixing plate 3 is fixedly connected to the auxiliary block 10, which has an L-shaped structure. The bent part of the auxiliary block 10 is slidably connected in the moving groove opened on the upper surface of the secondary horizontal plate 8. At the same time, the main fixing plate 2, the secondary fixing plate 3 and the reinforcing plate 19 are combined together to form an E-shaped structure.
[0022] In this embodiment, if Figure 1 , Figure 2 and Figure 4 The dimensions of the bending part of the auxiliary block 10 and the moving groove opened in the secondary horizontal plate 8 are matched, so it can help enhance the stability of the auxiliary block 10, the reinforcing plate 19, the secondary fixing plate 3 and the main fixing plate 2 when they move, and ensure the stability of the meshing between the rack and the drive wheel.
[0023] As a preferred embodiment, the fixed frame 11 has a U-shaped structure, and a positioning hole is opened on the lower surface of the fixed frame 11 corresponding to the position of the positioning rod 13. The positioning rod 13, which is slidably connected in the positioning hole, has a cylindrical structure. At the same time, the lower ends of the two sets of positioning rods 13 are fixedly connected to the two ends of the upper surface of the moving plate 15.
[0024] In this embodiment, if Figure 1 and Figure 2 The fixed frame 11 helps to enhance the stability of the fixed connection between the servo electric cylinder 12 and the auxiliary fixed plate 3, and the size of the positioning hole and the positioning rod 13 are compatible, which in turn helps to enhance the stability of the positioning rod 13 and the moving plate 15 when they move up and down.

At the same time, both sets of end buffer plates 16 have a convex structure, and the lower surface of the end buffer plate 16 has an arc-shaped structure.
[0028] In this embodiment, if Figure 1 , Figure 2 and Figure 3The lower surfaces of the side buffer plate 18 and the end buffer plate 16 are both fixedly connected with a buffer layer. The buffer layer is made of silicone, which can effectively reduce the probability of damage to the surface of the liquid crystal glass substrate when the side buffer plate 18 and the sub-buffer plate come into contact with it. In addition, the arc structure of the side buffer plate 18 and the end buffer plate 16 can effectively reduce the resistance when the side buffer plate 18 and the end buffer plate 16 slide on the surface of the liquid crystal glass substrate.
