Abstract
Description
Technical Field
[0001] This utility model relates to the field of pressing device technology, and more specifically, it relates to an alignment pressing device for LCD screen processing. Background Technology
[0002] In existing technologies, in existing LCD screen alignment and pressing devices, the unloading after pressing usually requires manual operation by workers. This manual operation not only greatly increases the labor intensity of workers, but also makes the unloading process very dangerous because the equipment and pressure head may be kept at a certain high temperature or high pressure during the pressing process.
[0003] In practical use, existing pressing devices are difficult to achieve precise alignment and stable pressing of LCD screens. Most devices rely on manual operation for initial alignment and manual adjustment of the workpiece to complete the pressing. This operation method is prone to positional deviations, affecting product quality. As the size and complexity of LCD screens increase, relying solely on manual adjustment cannot meet the high precision requirements.
[0004] For the fixing process of LCD screens, most existing pressing devices use static fixing or temporary clamping methods. This means that during the pressing operation, the LCD screen often requires manual intervention to ensure that it is fixed on the pressing platform. However, this fixing method cannot guarantee stability and may lead to positional displacement or uneven pressure distribution during the pressing process. Utility Model Content

[0016] (III) Beneficial Effects
[0017] Compared with the prior art, the present invention provides an alignment and pressing device for LCD screen processing, which has the following advantages:
[0018] 1. The striking component drives the actuating block to move the moving plate through the meshing of the rack and pinion, thereby moving the striking rod on the moving plate.

[0030] Please see Figures 1-5 An alignment and pressing device for LCD screen processing includes a fixed frame 1. A striking assembly is provided on the fixed frame 1. The striking assembly includes an operating table 2, a cylinder 3, a rack 4, a gear 5, and a toggle block 6. The operating table 2 is mounted on the fixed frame 1. The cylinder 3 is fixedly mounted on the operating table 2. The rack 4 is connected to the output end of the cylinder 3 and is slidably connected to the operating table 2. The gear 5 is rotatably connected to the operating table 2 and meshes with the rack 4. The toggle block 6 is connected to one end of the gear 5. A pressing assembly is provided on the operating table 2. The pressing assembly includes a fixed column 7, a top plate 8, and a hydraulic cylinder 9. The fixed column 7 is located on the operating table 2. The top plate 8 is located on the top of the fixed column 7. The hydraulic cylinder 9 is fixedly mounted on the top plate 8.
[0031] A fixed plate 10 is installed on the operating table 2, and a movable groove 11 is opened on the operating table 2. A movable plate 12 is slidably connected to the movable groove 11.
[0032] A striking rod 13 is evenly installed on the movable plate 12, and a spring 14 is sleeved on the striking rod 13. The two ends of the spring 14 are connected to the fixed plate 10 and the movable plate 12.
[0033] The output end of the hydraulic cylinder 9 is connected to a pressure plate 15, and a pressure block 16 is installed on the pressure plate 15. A guide rod 17 is slidably connected on the top plate 8, and one end of the guide rod 17 is connected to one end of the pressure plate 15. A motor 18 is installed on the operating table 2.
[0034] The output end of the motor 18 is connected to a threaded rod 19, and a pressing table 20 is threadedly connected to the threaded rod 19. The pressing table 20 is adapted to the pressing block 16. A guide rail 21 is installed on the operating table 2, and the pressing table 20 is slidably connected to the guide rail 21.
[0035] In this embodiment, during use, after the screen pressing process is completed, when it needs to be removed, the cylinder 3 is activated, causing the output rack 4 to move. During this movement, the rack 4, which meshes with the rack 5, rotates. This rotation causes the actuating block 6 on the rack 5 to rotate, continuously actuating the moving plate 12. This actuation causes the moving plate 12 to slide along the operating table 2, moving the striking rod 13. During use, this compresses the spring 14 between the moving plate 12 and the fixed plate 10. As the striking rod 13 moves, it passes through the fixed plate 10 and strikes... The screen is struck onto the pressing table 20, thus completing the striking process and allowing the screen to be easily removed from the pressing table 20. During use, after the screen is placed on the pressing table 20, the motor 18 is started, which drives the threaded rod 19 at the output end to rotate. During the rotation, the pressing table 20, which is threadedly connected to it, slides along the guide rail 21 to move to the appropriate position. Then, the hydraulic cylinder 9 on the top plate 8 is started, which drives the pressing plate 15 at the output end to move. During the movement, the guide rod 17 at one end of the plate slides along the top plate 8, thereby moving the pressing block 16 to a position that fits against the pressing table 20, thus completing the pressing process of the screen.
[0036] Please see Figure 4-5 As an embodiment of an LCD screen processing alignment and pressing device for fixing components: a fixing component is provided on the operating table 2. The fixing component includes a connecting box 22, a connecting hose 23, an air pump 24, and an air extraction hole 25. The connecting box 22 is installed on the operating table 2, the air pump 24 is installed at one end of the connecting box 22, the connecting hose 23 is connected between the pump body and the pressing table 20, and the air extraction holes 25 are evenly opened on the pressing table 20 and are connected to the connecting hose 23.
[0037] A stop block 26 is installed on the pressing table 20.
[0038] A rotating block 27 is rotatably connected to the pressing table 20, and one end of the rotating block 27 is in contact with the abutment block 26.
[0039] More specifically, during use, after the screen is placed on the pressing platform 20, the air pump 24 is activated, which uses the connecting hose 23 and the air extraction hole 25 on the pressing platform 20 to complete the adsorption process of the screen. During use, the rotating block 27 is rotated along the pressing platform 20, so that one end of it is attached to the abutment block 26, thereby abutting the screen and completing the fixing process.
[0040] In summary, during the use or operation of the overall equipment: After the screen pressing process is completed, when it needs to be removed, the cylinder 3 is activated, causing the output rack 4 to move. During this movement, the rack 4, which meshes with the gear 5, rotates. This rotation causes the actuating block 6 on the actuating block 6 to rotate, continuously actuating the moving plate 12. This actuation causes the moving plate 12 to slide along the operating table 2, moving the striking rod 13. During use, this compresses the spring 14 between the moving plate 12 and the fixed plate 10. As the striking rod 13 moves, it passes through the fixed plate... The fixed plate 10 strikes the pressing table 20, thus completing the striking process of the pressing table 20, making it easy to remove the screen from the pressing table 20. In use, after the screen is placed on the pressing table 20, the motor 18 is started, which drives the threaded rod 19 at the output end to rotate. During the rotation, the pressing table 20, which is threaded on it, slides along the guide rail 21, thus moving it to the appropriate position. Then, the hydraulic cylinder 9 on the top plate 8 is started, which drives the pressing plate 15 at the output end to move. During the movement, the guide rod 17 at one end of the pressing plate 15 slides along the top plate 8, thus moving the pressing block 16 to a position that fits against the pressing table 20, thereby completing the pressing process of the screen.
[0041] During use, after the screen is placed on the pressing platform 20, the air pump 24 is started, which uses the connecting hose 23 and the air extraction hole 25 on the pressing platform 20 to complete the adsorption process of the screen. During use, the rotating block 27 is rotated along the pressing platform 20, so that one end of it is attached to the abutment block 26, thereby abutting the screen and completing the fixing process.
