Description

Technical Field

[0001] This utility model relates to the field of hot pressing technology, and more specifically, to a hot pressing device for liquid crystal displays. Background Technology

[0002] In existing liquid crystal display (LCD) hot-pressing devices, the LCD pushing process exhibits significant instability. Traditional devices often employ simple linear guide rails with slider structures, lacking effective shock absorption and buffering mechanisms. When the moving cylinder pushes the moving plate, the inertia at the moment of start-up and stop easily generates impacts and vibrations, causing the LCD to wobble or shift during the pushing process. After prolonged use, the clearance between the guide rail and the slider increases, leading to wobble and shifting during the pushing process, severely affecting the smoothness of the pushing operation.

[0003] During hot pressing, the guiding system needs to withstand high pressure and high temperature, which places higher demands on the lubrication system. Existing devices cannot meet these special requirements, resulting in increased friction in the guiding system during hot pressing, affecting the accuracy and quality of hot pressing. Traditional devices often use manual oil injection or simple drip lubrication, which cannot achieve a continuous and uniform lubrication effect. During long-term operation, the lubrication effect gradually weakens, leading to increased friction in the guiding system. The lubrication points of traditional devices are set too concentratedly or too dispersedly, failing to cover all critical friction parts, resulting in insufficient lubrication in some areas and aggravating wear.

[0029] Please see Figures 1-5A liquid crystal display hot pressing device includes a platform 1, a moving conveying mechanism, a lubrication guiding mechanism, and a one-way sealing mechanism. The moving conveying mechanism includes a guide rail 2, a moving plate 3, a mounting plate assembly 4, a sliding sleeve 5, a limiting plate 6, and a moving hydraulic cylinder 7. The guide rail 2 is mounted on the top end of the platform 1, the sliding sleeve 5 is mounted on the bottom end of the moving plate 3, and the sliding sleeve 5 is slidably mounted on the guide rail 2.

The lubrication guiding mechanism includes a top fixing frame 8 and a guide rod 9. The system includes a pressure plate 10, a guide sleeve 11, a one-way tube 12, a sealing plate 13, a sealing platform 14, and a sealing spring 15. A guide rod 9 is installed on the top end of the top plate 23. The guide sleeve 11 is installed on the pressure plate 10 and is slidably installed on the guide rod 9. The one-way tube 12 is set on the side wall of the guide sleeve 11. The sealing platform 14 and the top fixing frame 8 are installed on the inner wall of the one-way tube 12. The sealing plate 13 is slidably installed inside the one-way tube 12. The sealing spring 15 is installed between the sealing plate 13 and the top fixing frame 8. The sealing spring 15 pushes the sealing plate 13 to cooperate with the sealing platform 14 to set up a one-way sealing.

[0030] In this embodiment, the guide rail 2 is installed on the top of the platform 1, providing a stable guiding foundation for the entire moving system. The moving plate 3 slides on the guide rail 2 via the bottom sliding sleeve 5, ensuring the accuracy of the movement trajectory. The mounting plate assembly 4 is installed on the top of the moving plate 3 to fix the liquid crystal display to be processed. The limiting plate 6 is installed at one end of the guide rail 2 to limit the stroke range of the moving plate 3 and prevent excessive movement. One end of the moving cylinder 7 is connected to the moving plate 3, providing a smooth pushing force through hydraulic control, so that the moving plate 3 moves precisely along the guide rail 2, realizing the precise positioning of the liquid crystal display and providing a reliable foundation for the subsequent hot pressing process. The guide rod 9 is installed on the top plate. The top of the 23 provides a guide for the vertical movement of the pressure plate 10. The pressure plate 10 slides on the guide rod 9 through the guide sleeve 11 to ensure the verticality and stability of the hot pressing action. The one-way tube 12 is set on the side wall of the guide sleeve 11 and has a sealing platform 14 and a top fixing frame 8 inside. The sealing plate 13 slides in the one-way tube 12 and forms a one-way seal with the sealing platform 14 through the sealing spring 15. When the external oil supply mechanism applies pressure to the sealing plate 13 through the pressing block 28, the sealing spring 15 is compressed, allowing lubricating oil to enter the guide system through the one-way tube 12. The design not only ensures the lubrication effect but also prevents the backflow of lubricating oil, improving the reliability and service life of the system.

[0031] The one-way sealing mechanism includes a sliding rod 16, a push block 17, a tightening spring 18, a tightening block 19, a bottom fixing frame 20, a stabilizing groove 21, and a spring rod 22. The sliding rod 16 is installed at one end of the sealing plate 13, and the push block 17 is installed at one end of the sliding rod 16. Multiple sets of tightening springs 18 are arranged in a ring on the inner wall of the one-way tube 12. The tightening block 19 is installed at one end of the tightening springs 18. The bottom fixing frame 20 is fixedly installed on the inner wall of the one-way tube 12. The stabilizing groove 21 is located at the top of the bottom fixing frame 20. The spring rod 22 at the bottom end of the tightening block 19 can extend into the stabilizing groove 21 step by step, so that the tightening block 19 can move stably. If the sliding rod 16 moves in the opposite direction, the push block 17 can push against the tightening block 19 to spread out, so that the one-way tube 12 communicates with the interior of the sliding sleeve.

[0032] In this embodiment, the sliding rod 16 is installed at one end of the sealing plate 13, the push block 17 is installed at the end of the sliding rod 16, multiple sets of tightening springs 18 are arranged in a ring on the inner wall of the one-way tube 12, the tightening block 19 is installed at the end of the tightening springs 18, and the bottom bracket 20 is fixed to the inner wall of the one-way tube 12. The stabilizing groove 21 at the top of the bottom bracket 20 cooperates with the spring rod 22 at the bottom of the tightening block 19. When the sliding rod 16 moves forward, the push block 17 pushes the tightening block 19, causing its spring rod 22 to extend into the stabilizing groove 21 step by step, forming a stable sealing state. When the sliding rod 16 moves in the reverse direction, the push block 17 pushes against the tightening block 19 to make it open, allowing the one-way tube 12 to communicate with the inside of the sliding sleeve. This achieves precise control of the lubrication system, ensuring that the lubricating oil can pass smoothly when needed and maintain a sealed state when not needed.

[0033] Please see Figures 1-5 As a supplementary embodiment of a liquid crystal display hot pressing device for a moving conveying mechanism, a lubrication guiding mechanism, and a one-way sealing mechanism: A top plate 23 is installed at the top end of the guide rod 9, and a hot pressing cylinder 24 is installed at the top end of the top plate 23. One end of the hot pressing cylinder 24 is connected to the pressure plate 10. Support legs 25 are installed around the bottom end of the platform 1, and the support legs 25 are in contact with the contact surface for support. A side platform 26 is installed on the side of the platform 1, and the bottom end of the moving cylinder 7 is installed on the side platform 26. A support tube 27 is installed on the side of the guide sleeve 11, and one end of the one-way tube 12 is connected to one end of the support tube 27. A pressing block 28 is installed on one end face of the sealing plate 13. An external oil supply mechanism presses against the pressing plate 10 to compress the push spring. A hot pressing assembly 29 is installed at the bottom end of the pressure plate 10, and one end face of the hot pressing assembly 29 can press against the top end of the mounting plate assembly 4.

[0034] More specifically, the operator places the LCD monitor to be processed on the mounting plate assembly 4, checks the status of each mechanism, activates the moving cylinder 7, pushes the moving plate 3 along the guide rail 2 to precisely position the LCD monitor at the hot pressing position, and the limiting plate 6 ensures that the moving plate 3 does not exceed the predetermined range. The external oil supply mechanism applies pressure to the sealing plate 13 through the pressing block 28, compressing the sealing spring 15 and opening the one-way sealing mechanism. Lubricating oil enters the guide system through the one-way pipe 12 to provide necessary lubrication for the hot pressing process. The hot pressing cylinder 24 is activated, pushing the pressure plate 10 along the guide rail. As lever 9 moves downwards, the hot-pressing assembly 29 at the bottom of pressure plate 10 contacts the LCD display, applying precise hot-pressing treatment. During the hot-pressing process, the one-way sealing mechanism, through the cooperation of tension spring 18 and tension block 19, controls the pressure of the lubrication system, ensuring the stability and accuracy of the hot-pressing process. After hot-pressing is completed, the hot-pressing cylinder 24 retracts, pressure plate 10 rises, and the moving cylinder 7 moves in the opposite direction, removing the processed LCD display from the working area. The external oil supply mechanism stops applying pressure, sealing spring 15 returns to its original state, and the one-way sealing mechanism closes to prevent backflow of lubricating oil. The system is ready for the next processing cycle.

[0035] In summary, during the use or operation of the overall equipment: when the moving conveyor mechanism is required, it is responsible for the precise positioning and transport of the LCD display. The guide rail 2 is installed on the top of the platform 1, providing a stable guiding foundation for the entire moving system. The moving plate 3 slides on the guide rail 2 through the bottom sliding sleeve 5, ensuring the accuracy of the movement trajectory. The mounting plate assembly 4 is installed on the top of the moving plate 3 to fix the LCD display to be processed. The limiting plate 6 is installed at one end of the guide rail 2 to limit the travel range of the moving plate 3 and prevent excessive movement. One end of the moving cylinder 7 is connected to the moving plate 3, providing a smooth pushing force through hydraulic control, so that the moving plate 3 moves precisely along the guide rail 2, realizing the precise positioning of the LCD display and providing a reliable foundation for the subsequent hot pressing process.

[0036] When the lubrication guide mechanism is in operation, it ensures precise guidance and lubrication during the hot pressing process. The guide rod 9 is installed on the top of the top plate 23 to provide vertical guidance for the pressure plate 10. The pressure plate 10 slides on the guide rod 9 through the guide sleeve 11 to ensure the verticality and stability of the hot pressing action. The one-way tube 12 is set on the side wall of the guide sleeve 11 and has a sealing platform 14 and a top fixing frame 8 inside. The sealing plate 13 slides in the one-way tube 12 and forms a one-way seal with the sealing platform 14 through the sealing spring 15. When the external oil supply mechanism applies pressure to the sealing plate 13 through the pressing block 28, the sealing spring 15 is compressed, allowing lubricating oil to enter the guide system through the one-way tube 12. The design ensures the lubrication effect and prevents the backflow of lubricating oil, thereby improving the reliability and service life of the system.

[0037] When the one-way sealing mechanism is required to operate, the sliding rod 16 is installed at one end of the sealing plate 13, the push block 17 is installed at the end of the sliding rod 16, multiple sets of tightening springs 18 are arranged in a ring on the inner wall of the one-way tube 12, the tightening block 19 is installed at the end of the tightening springs 18, and the bottom bracket 20 is fixed to the inner wall of the one-way tube 12. The stabilizing groove 21 at its top cooperates with the spring rod 22 at the bottom of the tightening block 19. When the sliding rod 16 moves forward, the push block 17 pushes the tightening block 19, causing its spring rod 22 to extend into the stabilizing groove 21 step by step, forming a stable sealing state. When the sliding rod 16 moves in the reverse direction, the push block 17 pushes against the tightening block 19 to make it open, allowing the one-way tube 12 to communicate with the inside of the sliding sleeve. This achieves precise control of the lubrication system, ensuring that the lubricating oil can pass smoothly when needed and maintain a sealed state when not needed.

[0038] The operator places the LCD monitor to be processed on the mounting plate assembly 4, checks the status of each mechanism, activates the moving cylinder 7, pushes the moving plate 3 along the guide rail 2 to precisely position the LCD monitor at the hot pressing position, and the limiting plate 6 ensures that the moving plate 3 does not exceed the predetermined range. The external oil supply mechanism applies pressure to the sealing plate 13 through the pressing block 28, compressing the sealing spring 15 and opening the one-way sealing mechanism. Lubricating oil enters the guiding system through the one-way pipe 12 to provide necessary lubrication for the hot pressing process. The hot pressing cylinder 24 is activated, pushing the pressure plate 10 along the guide rod 9. Moving downwards, the hot-pressing assembly 29 at the bottom of the pressure plate 10 contacts the LCD display, applying precise hot-pressing treatment. During the hot-pressing process, the one-way sealing mechanism, through the cooperation of the tightening spring 18 and the tightening block 19, controls the pressure of the lubrication system, ensuring the stability and accuracy of the hot-pressing process. After hot-pressing is completed, the hot-pressing cylinder 24 retracts, the pressure plate 10 rises, and the moving cylinder 7 moves in the opposite direction, moving the processed LCD display out of the working area. The external oil supply mechanism stops applying pressure, the sealing spring 15 returns to its original state, and the one-way sealing mechanism closes to prevent backflow of lubricating oil. The system is ready for the next processing.
