[0017] Reference Figures 1 to 4As shown, this utility model provides a liquid crystal glass substrate cutting and positioning mechanism, including: a carrier plate 2, with sealing plates 1 symmetrically connected to both ends of the carrier plate 2, a main lead screw 4 movably connected to one end of the sealing plate 1 via a bearing, a main motor 8 connected to the main lead screw 4 via a coupling, and the main motor 8 fixedly connected to the surface of the sealing plate 1, and main slide grooves 3 symmetrically opened on both sides of the carrier plate 2, a main slider 7 slidably connected to the main slide groove 3 via the screwed main lead screw 4, and a positioning plate 6 fixedly connected to the surface of the main slider 7, with a secondary lead screw 11 movably connected to the upper end of the surface of the positioning plate 6 via a bearing, and a moving plate 9 slidably connected to the surface of the positioning plate 6 via the screwed secondary lead screw 11, with the bent part of the positioning block 5 fixedly connected to the upper surface of the moving plate 9, and the main body of the positioning block 5 slidably connected to the surface of the positioning plate 6 away from the secondary lead screw 11.

[0018] In this embodiment, the liquid crystal glass substrate to be cut is placed on the upper surface of the carrier plate 2. The main motor 8 is turned on, and the output shaft of the main motor 8 drives the main lead screw 4 to rotate through the coupling. The main lead screw 4 drives the two sets of positioning plates 6 to move relative to each other through the screwed main slider 7. This allows the two sets of positioning plates 6 to abut against the two sides of the liquid crystal glass substrate through the buffer groove, completing the initial positioning of the liquid crystal glass substrate. When the auxiliary lead screw 11 is rotated, the auxiliary lead screw 11 drives the positioning block 5 to move synchronously through the screwed moving plate 9. Then, the two sets of positioning blocks 5 at both ends of the same set of positioning plates 6 can move relative to each other, so that the positioning blocks 5 can perform corresponding positioning and clamping on both ends of the liquid crystal glass substrate. This allows the liquid crystal glass substrate to be positioned and fixed in multiple directions on the surface of the carrier plate 2, enhancing the positioning and fixing effect of the liquid crystal glass substrate, avoiding the problem of accidental displacement of the liquid crystal glass substrate during subsequent cutting, and ensuring the cutting effect of the liquid crystal glass substrate.

[0019] In a preferred embodiment, the two sets of sealing plates 1 fixedly connected to both ends of the carrying plate 2 are both rectangular in structure, and the size of the sealing plate 1 is adapted to the size of the end face of the carrying plate 2. A set of main screws 4 is movably connected between the two sets of sealing plates 1, and the main screws 4 are movably connected in the main sliding groove 3 opened on the side of the carrying plate 2.

[0020] In this embodiment, as Figure 1 , Figure 2 and Figure 3 The sealing plate 1 can close both ends of the main slide 3, thereby limiting the movement range of the main slider 7 and also assisting in the installation of the main lead screw 4 and the main motor 8. The main motor 8 can be a servo motor.

[0021] As a preferred embodiment, the two sets of main slide grooves 3 opened on both sides of the carrier plate 2 are both long strip structures. The cross-section of the main slide groove 3 is square, and the size of the main slide groove 3 and the main slider 7 are matched. The positioning plate 6 fixedly connected to the main slider 7 is U-shaped, and the lower surface of the middle part of the positioning plate 6 is attached to the upper surface of the carrier plate 2.

[0022] In this embodiment, as Figure 1 , Figure 2 and Figure 3 The main slide groove 3 and the main slider 7 are matched in size, which helps to enhance the stability of the main slider 7 and the positioning plate 6 when they move, thereby avoiding the problem of the positioning plate 6 tilting and shaking unexpectedly when positioning and fixing the liquid crystal glass substrate.

[0023] As a preferred embodiment, two sets of secondary sliding grooves 13 are provided on the side of the positioning plate 6 near the sealing plate 1, and both sets of secondary sliding grooves 13 are elongated structures. Both sets of secondary sliding grooves 13 penetrate the end faces of both ends of the positioning plate 6. Meanwhile, the other side of the positioning plate 6 is fixedly connected to a buffer layer through a groove, and the buffer layer is rectangular in structure.

[0024] In this embodiment, as Figure 2 , Figure 3 and Figure 4 The buffer layer can be made of silicone, which can help enhance the positioning and contact effect of the positioning plate 6 on the side of the liquid crystal glass substrate, and also help reduce the chance of accidental damage to the side of the liquid crystal glass substrate due to excessive force during initial positioning.

[0025] In a preferred embodiment, the movable plate 9 has a rectangular structure, and the position of the movable plate 9 relative to the secondary slide groove 13 is connected to the secondary slider 10. Both sets of secondary sliders 10 have a square structure, and the movable plate 9 and the secondary sliders 10 are combined to form a Π-shaped structure.

[0026] In this embodiment, as Figure 1 , Figure 2 and Figure 3 The sizes of the secondary slider 10 and the secondary slide groove 13 are matched, which can help enhance the stability of the moving plate 9 and the positioning block 5 when they move on the surface of the positioning plate 6, thereby ensuring the positioning and clamping effect of the positioning block 5 on the liquid crystal glass substrate.

[0027] In a preferred embodiment, the mating block 12 fixedly connected to the upper surface of the movable plate 9 has a cubic structure, and a screw hole is opened in the middle of the upper surface of the mating block 12. The position of the bent part of the positioning block 5 relative to the position of the mating block 12 is provided with a mating groove, and the top of the inner cavity of the mating groove is provided with a through hole relative to the position of the screw hole. The bolt passes through the through hole and is screwed into the screw hole. At the same time, the movable plate 9 and the positioning plate 6 are fixedly connected by bolts.

[0028] In this embodiment, as Figure 2 , Figure 3 and Figure 4The size of the fitting block 12 and the fitting groove are matched, which helps to enhance the stability of the fixed connection between the moving plate 9 and the positioning block 5, and prevents the positioning block 5 from accidentally tilting or loosening when positioning and clamping the liquid crystal glass substrate. At the same time, the connection method between the moving plate 9 and the positioning block 5 makes it easy for workers to replace the positioning block 5 with different sizes and structures according to the actual situation, further enhancing the flexibility and convenience of the positioning mechanism in actual use.

[0029] In a preferred embodiment, the positioning block 5 has an L-shaped structure. The main body of the positioning block 5 is slidably connected to the surface of the buffer layer, and the positioning block 5 and the moving plate 9 are combined to form a U-shaped structure. At the same time, the lower surface of the main body of the positioning block 5 slides against the upper surface of the carrier plate 2.

[0030] In this embodiment, as Figure 1 , Figure 2 and Figure 3 The structural arrangement of the positioning block 5 and the moving plate 9 enables the positioning block 5 to slide stably on the surface of the positioning plate 6, thereby enhancing the positioning and fixing effect of the positioning mechanism on liquid crystal glass substrates of different sizes.

[0031] The liquid crystal glass substrate cutting and positioning mechanism of this utility model, through the cooperation of the main lead screw 4, the main slider 7, the positioning plate 6, the auxiliary lead screw 11, the moving plate 9 and the positioning block 5, enables the mechanism to position and fix liquid crystal glass substrates of different sizes on the surface of the carrier plate 2, thereby ensuring the stability during subsequent cutting and enhancing the flexibility of the positioning mechanism during use. At the same time, the surface of the carrier plate 2 is flat and smooth without grooves, which can avoid the residue of debris generated during the cutting of liquid crystal glass substrates and reduce the difficulty of subsequent cleaning.
