[0002] Liquid crystal screens use liquid crystal materials as their basic components. Liquid crystal materials are filled between two parallel plates. Voltage is used to change the arrangement of molecules inside the liquid crystal material to achieve the purpose of light blocking and light transmission to display images of varying depths and staggered patterns. Moreover, as long as a filter layer of three primary colors is added between the two plates, color images can be displayed. During the production process of LCD screens, film lamination is required, and film lamination equipment is required. A film lamination equipment has the following technologies:
[0003] 1. The equipment is equipped with a high-performance micro vacuum pump that can quickly generate negative pressure and tightly adsorb the screen onto the workbench, thereby ensuring stability during the film lamination process. This workbench is a mechanism for positioning the LCD screen during production and processing.
[0004] 2. Control system, used to control the switch of the micro vacuum pump and the movement of the workbench to achieve automatic control.
[0005] At present, the existing equipment is suitable for the bonding processing of various materials such as OCA (optically clear adhesive), polarizing film, protective film, etc., and can meet the production needs of different LCD screens. In order to ensure that some special screens maintain accurate position during the bonding or processing process, two limit plates will be installed on the workbench. The limit plates can position the two ends of the screen, and the limit plates are fixed to the workbench through threaded connections.
[0006] However, there is a problem in this process. The threaded connection method makes it difficult to adjust the position of the limit plate, which limits the adaptability of the limit plate to screens of different sizes. This application proposes a solution to this problem. By setting an adjustment mechanism, the position of the limit plate can be adapted to screens of different sizes, thereby improving the flexibility of the device. Utility Model Content

[0024] The embodiment of the present application provides a positioning device for the production and processing of liquid crystal screens, which effectively solves the problem that the limit plate 6 is fixed to the workbench 2 through a threaded connection to limit the movement of the screen during the film application process. However, the threaded connection method makes it difficult to adjust the position of the limit plate 6, which limits the adaptability of the limit plate 6 to screens of different sizes.
[0025] Example
[0026] like Figure 1 , Figure 2 , Figure 3 and Figure 4 The technical solution in the embodiment of the present application is to effectively solve the problem of fixing the limit plate 6 on the workbench 2 through a threaded connection to limit the movement of the screen during the film application process. However, the threaded connection method makes it difficult to adjust the position of the limit plate 6, which limits the adaptability of the limit plate 6 to screens of different sizes. The overall idea is as follows:
[0027] In response to the problems existing in the prior art, the utility model provides a liquid crystal screen production and processing positioning device, which includes a body 1, a workbench 2 is fixedly installed on the outside of the body 1, and an adjustment mechanism is provided on the outside of the body 1. The adjustment mechanism includes a mounting plate 3, a threaded rod 4, a rotating disk 5 and a limit plate 6. There are two mounting plates 3, and the two mounting plates 3 are fixedly mounted at both ends of the body 1. The two ends of the threaded rod 4 are respectively rotatably connected to the outside of the two mounting plates 3. The threaded rod 4 has two threads in different directions. The rotating disk 5 is fixedly mounted on the outside of the threaded rod 4. The rotating disk 5 is composed of a cylinder and a thread in the cylinder. The rotating disk 5 is located between the two mounting plates 3. There are two limit plates 6. One end of the two limit plates 6 is threadedly connected to the outside of the threaded rod 4. The other end of the two limit plates 6 is slidably connected to the upper surface of the workbench 2. The two limit plates 6 are located at both ends of the rotating disk 5. The two limit plates 6 are located between the two mounting plates 3. By setting the limit plates 6 and cooperating with the threaded rod 4, the rotating disk 5 is turned to rotate the threaded rod 4. At this time, the two limit plates 6 move. When the limit plates 6 move to the appropriate position, the rotating disk 5 can no longer be turned. The position of the limit plates 6 can be adjusted to adapt to screens of different sizes and shapes, thereby improving the flexibility of the positioning device.
[0028] Two limit plates 7 are fixedly installed at both ends of the threaded rod 4. The two limit plates 7 are respectively located at both ends of the mounting plate 3, which are the connection structure between the threaded rod 4 and the mounting plate 3 to prevent the connection between the threaded rod 4 and the mounting plate 3 from being released. Each mounting plate 3 is provided with a through hole 8, and a short plate 9 is slidably connected to the inside of each through hole 8. The short plate 9 is fixedly installed on the outside of the limit plate 6 to limit the vertical movement of the limit plate 6.
[0029] The outside of the body 1 is slidably connected to a baffle 10, and a pressure plate 11 is fixedly installed on the outside of the baffle 10. The pressure plate 11 is a concave body. A plurality of protrusions 12 are fixedly installed on the outside of the rotating disk 5. The baffle 10 is located between the two protrusions 12 to facilitate fixing the rotating disk 5. A groove 13 is provided on the outside of the body 1. A spring 14 is fixedly connected to the inside of the groove 13. The baffle 10 is fixedly connected to the outside of the spring 14. A built-in groove 15 is provided inside the groove 13. The built-in plate 16 is slidably connected to the inside of the built-in groove 15. The built-in plate 16 is fixedly installed on the outside of the baffle 10. The baffle 10 is prevented from being disconnected from the groove 13 by providing the baffle 10 and cooperating with the protrusion 12. When the rotating disk 5 rotates, the pressure plate 11 is pressed to drive the baffle 10 to move downward. At this time, the connection between the protrusion 12 and the baffle 10 is released, and the rotating disk 5 can be rotated. When the limit plate 6 moves to a suitable position, the pressure plate 11 is released. Under the action of the spring 14, the baffle 10 moves upward until the baffle 10 is located between the two protrusions 12. At this time, the rotating disk 5 is fixed, thereby reducing the probability of unintentional rotation of the rotating disk 5, thereby improving the stability of the limit plate 6.
[0030] Working principle:
[0031] In the first step, when the limit plate 6 is moved, the pressure plate 11 is pressed to drive the baffle 10 to move downward. At this time, the connection between the protrusion 12 and the baffle 10 is released, and the spring 14 is compressed. At this time, the rotating disk 5 can be rotated. Since the threaded rod 4 is composed of two screws with threads in opposite directions, when the threaded rod 4 is driven by the rotating disk 5 to rotate, the two limit plates 6 will move in one direction or in two directions at the same time;
[0032] In the second step, after the limit plate 6 moves to the appropriate position, the pressure plate 11 is released, and the baffle 10 moves upward under the action of the spring 14 until the baffle 10 is located between the two protrusions 12. At this time, the rotating disk 5 is fixed, thereby reducing the probability of the rotating disk 5 rotating unintentionally, thereby improving the stability of the limit plate 6. By adjusting the position of the limit plate 6 to adapt to screens of different sizes, the flexibility of the positioning device is improved.
[0033] Finally, it should be noted that the above embodiments are merely examples for the purpose of illustrating the present invention and are not intended to limit the embodiments. Those skilled in the art will readily appreciate that other variations or modifications based on the above description are possible. It is not necessary and impossible to provide an exhaustive list of all possible embodiments. However, any obvious variations or modifications arising therefrom remain within the scope of protection of the present invention.
