Description

Technical Field

[0001] This invention relates to the field of screen cleaning technology, and in particular to a cleaning device for liquid crystal display components. Background Technology

[0002] Liquid crystal displays (LCDs) are a type of flat panel display used in televisions and computers. LCDs use a liquid crystal solution in two polarizing materials. When an electric current passes through the liquid, the crystals rearrange to achieve the purpose of image formation.

[0003] If air bubbles, foreign objects, or poor bonding occur during the assembly or bonding of LCD screens, the OCA adhesive must be peeled off and re-bonded. In multi-layer OCA adhesive bonding processes, if a layer of adhesive is defective, the OCA adhesive must also be removed and recoated.

[0004] Existing technologies for removing OCA adhesive from LCD screens typically employ a rolling removal method. This method uses silicone rollers to push the OCA adhesive out of the screen, thus removing it. However, when these rollers push the OCA adhesive, the adhesive not only accumulates and moves in the pushing direction but also to the sides of the screen, leaving residue on the screen after cleaning. Additionally, adhesive residue may remain on the silicone rollers themselves. Furthermore, after the rollers push the adhesive out, some residue remains at the edges of the screen, requiring manual removal or moving the screen to the next step for edge removal. This necessitates the use of multiple devices to remove the adhesive from the entire screen, resulting in a cumbersome and inefficient removal process.

[0005] Therefore, there is an urgent need to provide cleaning devices that can improve the adhesive removal effect and efficiency on the surface of LCD screens. Summary of the Invention

[0035] To make the above-mentioned objects, features, and advantages of the present invention more apparent and understandable, specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings. Many specific details are set forth in the following description to provide a thorough understanding of the present invention. However, the present invention can be practiced in many other ways different from those described herein, and those skilled in the art can make similar modifications without departing from the spirit of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0036] See Figures 1-3 A liquid crystal display assembly cleaning device includes a workbench 1, with a moving assembly 2 and a pressing assembly 3 connected to the upper end of the workbench 1.

[0037] See Figure 1 and Figure 4 The movable assembly 2 includes two guide rail rods 20 symmetrically mounted on the upper end of the worktable 1 via mounting bases. Sliding blocks 21 are sleeved and connected to both guide rail rods 20. Movable plates 22 are mounted on both sliding blocks 21. A connecting protrusion is integrally formed in the middle of the lower end of the movable plate 22. A transmission screw 23 is threadedly connected to the connecting protrusion. The transmission screw 23 is rotatably connected to the mounting base via bearings. The mounting base is fixedly connected to the upper end of the worktable 1. A drive motor 24 is fixedly connected to the end of the transmission screw 23. The drive motor 24 is fixedly connected to the upper end of the worktable 1 via a motor mount.

[0038] In actual operation, the workbench 1 is the existing control console. The workbench 1 is fixed in the working position, and then the drive motor 24 is connected to the external power supply. The drive motor 24 drives the transmission screw 23 to rotate. The transmission screw 23 drives the moving plate 22 to move through the connecting protrusion, thereby realizing the function of moving the display screen. The two guide rails 20 guide the movement of the moving plate 22 through the two sliding blocks 21.

[0039] See Figure 1 , Figure 4 and Figure 5 The LCD screen assembly cleaning device also includes a support group 4, which is connected to the movable group 2 and is used to place the LCD screen. The support group 4 includes a support plate 40 connected to the movable group 2. The upper end of the movable plate 22 is fixedly connected to the support plate 40, and a collection frame 41 is detachably connected to the left end of the support plate 40.

[0040] See Figure 1 , Figure 4 and Figure 5 The collection frame 41 has an upward-facing U-shaped structure. An installation strip 410 is integrally formed on the right end of the collection frame 41. The installation strip 410 is fixedly connected to the support plate 40 by bolts. An inclined baffle 411 is integrally formed on the upper end of the left side wall of the collection frame 41.

[0041] See Figure 1 , Figure 4 and Figure 5 The support assembly 4 also includes a limiting strip 42 installed on the upper surface of the support plate 40, the limiting strip 42 being located at the upper side of the support plate 40.

[0042] In practice, after the workbench 1 is fixed, the mounting strip 410 on the right end of the collection frame 41 is moved to the lower end of the support plate 40, and then the mounting strip 410 is fixed to the lower end of the support plate 40 with bolts, thereby realizing the function of installing the collection frame 41. The upper end of the side wall of the collection frame 41 that is in contact with the end of the support plate 40 is on the same plane as the upper end of the limiting strip 42. Then, the display screen that needs to be cleaned is placed on the upper end of the support plate 40. When placing it, ensure that the two sides of one corner of the display screen are in close contact with the limiting strip 42 and the side wall of the collection frame 41 respectively. The height of the upper surface of the display screen is higher than the upper end of the right side wall of the collection frame 41 and the upper end of the limiting strip 42 to ensure that the glue cleaned on the display screen can fall into the collection frame 41. At this time, the support plate 40 is located at the leftmost side of the workbench 1, which is the initial position of the glue removal work.

[0043] See Figure 1 and Figure 3 The pressing group 3 includes a CNC module 30 installed on the upper end of the workbench 1, and two lifting rods 31 are connected to the CNC module 30.

[0044] See Figure 1 , Figure 6 and Figure 7 The LCD screen assembly cleaning device also includes a roller cleaning group 5, which is connected to the lower pressure group 3 and located above the support plate 40. The roller cleaning group 5 includes a support part 50 connected to the lower pressure group 3. The support part 50 includes two symmetrically distributed support rods 500 that are slidably connected to the upper end of the worktable 1. The upper ends of the two support rods 500 are jointly mounted with a support plate 501. The lower ends of the two lifting rods 31 are fixedly connected to the upper end of the support plate 501. The outer periphery of the support rods 500 is fitted with a support spring 502 that is fixedly connected to the lower end of the support plate 501.

[0045] In actual operation, the CNC module 30 is an existing CNC hydraulic mechanism. The CNC module 30 controls the lifting and lowering of the two lifting rods 31. In the initial state, the two lifting rods 31 drive the support plate 501 to the highest position. The two support rods 500 are slidably connected to the worktable 1 and are in a vertical state, thereby realizing the guiding function of the movement of the support plate 501. At the same time, the support spring 502 plays a buffering role in the descent of the support plate 501 and a resetting role in the rise of the support plate 501.

[0046] See Figure 1 , Figure 6 and Figure 7 The lower end of the support plate 501 is equipped with a U-shaped connecting frame 51 with the opening facing downward and a scraping part 54. A roller 52 is rotatably connected to the connecting frame 51, and a side cleaning part 53 is connected to the roller 52.

[0047] See Figure 1 , Figure 6 and Figure 7 The side cleaning section 53 includes two ring plates 530 sleeved on the roller 52. The lower half of the ring plate 530 is provided with an avoidance opening, and the lower end of the ring plate 530 is provided with a material passage notch. Side cleaning plates 531 are installed at the opposite ends of the two ring plates 530. One ring plate 530 is fixedly connected to the inner end of the vertical section of the connecting frame 51 through a connecting seat. The other ring plate 530 is threadedly connected to a threaded rod 532 through a connecting plate. The threaded rod 532 is rotatably connected to the two vertical sections of the connecting frame 51. A scraper strip 533 fixedly connected to the connecting frame 51 is provided on one side of the roller 52. The side cleaning section 53 also includes a second drive motor 534 installed at the end of the threaded rod 532. The second drive motor 534 is fixedly connected to the vertical section of the connecting frame 51.

[0048] In actual operation, in the initial state, drive motor 534 is connected to an external power source. Support plate 501 drives roller 52 to its highest position through connecting frame 51. Then, according to the width of the display screen, drive motor 534 is started. Drive motor 534 drives threaded rod 532 to rotate. Threaded rod 532 drives corresponding ring plate 530 to move through connecting plate. The moving ring plate 530 drives corresponding side cleaning plate 531 to move, thereby changing the distance between the two side cleaning plates 531 to match the width of the display screen.

[0049] See Figure 1 , Figure 6 and Figure 7 The side cleaning plate 531 is located at the lower end of the roller 52, and the scraping surface of the side cleaning plate 531 is in the same vertical plane as the axis of the roller 52.

[0050] See Figure 1 , Figure 6 and Figure 7 The rolling cleaning assembly 5 also includes a drive unit 55 for driving the rolling roller 52 to rotate. The drive unit 55 includes a drive motor 550 mounted on the support unit 50. Two pulleys 551 are provided on one side of the drive motor 550. The two pulleys 551 are respectively mounted on the output shaft of the drive motor 550 and the end of the rolling roller 52. A transmission belt 552 is connected between the two pulleys 551.

[0051] In actual operation, initially, drive motor 3550 is connected to an external power source. After the spacing between the two side cleaning plates 531 is adjusted, CNC module 30 controls the two lifting rods 31 to move the support plate 501 downward. The support plate 501, through connecting frame 51, moves the rolling roller 52 downward until the lower end of the rolling roller 52 is on the same plane as the upper surface of the display screen. At this time, the rolling roller 52 is located at the end of the display screen. At the same time, the rolling roller 52 moves the two ring plates 530 downward. The two ring plates 530 respectively move the two side cleaning plates 531 to the two sides of the display screen. The lower end of the side cleaning plates 531 passes over the upper surface of the display screen. Then, drive motor 350 and drive motor 124 are started simultaneously. Drive motor 350 drives the corresponding pulley 551 to rotate. The pulley 551 drives the other pulley 551 to rotate through the transmission belt 552, thereby driving the rolling roller 52 to rotate. Simultaneously, the drive motor 24 drives the transmission screw 23 to rotate. The transmission screw 23 drives the moving plate 22 to move through the connecting protrusion. The moving plate 22 drives the display screen to move towards the lower end of the roller 52 through the support plate 40. The rotating roller 52 squeezes and removes the adhesive on the upper end of the display screen. The scraping surface of the side cleaning plate 531 is on the same vertical plane as the axis of the roller 52, which can ensure that the roller 52 first squeezes and removes the adhesive on the surface of the display screen. Then, the side cleaning plate 531 scrapes off the adhesive that has been squeezed and moved to both sides of the display screen, avoiding the presence of adhesive residue on the display screen after cleaning. This ensures that all the adhesive on the surface of the display screen can be removed. The roller 52 continues to work until the adhesive on the display screen is pushed to the end. While scraping off the adhesive on both sides of the display screen, the side cleaning plate 531 limits the display screen to prevent the display screen from tilting during the adhesive removal process.

[0052] See Figure 7 Both ring plates 530 are provided with placement openings 535 for placing scraper strips 533, and a scraper block 536 located above the scraper strips 533 is installed at the front end of the rear ring plate 530.

[0053] In actual operation, when the roller 52 removes adhesive from the display screen, the scraper strip 533 scrapes off the adhesive residue on the surface of the roller 52, preventing the adhesive residue on the surface of the roller 52 from causing secondary adhesion to the display screen and ensuring the adhesive removal effect of the roller 52.

[0054] See Figures 6-8 The scraping part 54 includes a scraper 540 located on the right side of the roller 52. The scraper 540 is used to remove residual adhesive from the side cleaning plate 531. The front end of the scraper 540 is on the same plane as the rear end face of the front side cleaning plate 531.

[0055] See Figures 6-8The scraping part 54 also includes a hydraulic push rod 541 mounted on the support part 50 via a push rod seat. A U-shaped sliding frame 542 is mounted on the left end of the hydraulic push rod 541. Z-shaped guide rail frames 543, which are fixedly connected to the push rod seat, are provided on both the front and rear sides of the sliding frame 542. Two vertical guide rods 544 are installed inside the sliding frame 542. A Z-shaped connecting plate 545 is sleeved on both guide rods 544. The lower right end face of the connecting plate 545 is close to the bottom wall of the sliding frame 542. The scraping part 54 is equipped with a return spring 546 and a moving groove opened at the left end of the connecting plate 545. A horizontal guide rod 547 is installed in the moving groove. A feed rod 549 is slidably sleeved on the guide rod 547. A return spring 548 is installed between the feed rod 549 and the end wall of the moving groove. The left end of the feed rod 549 is fixedly connected to the scraping plate 540. Two sliding rods are symmetrically installed at the front and back on the right side of the connecting plate 545. The connecting plate 545 is slidably connected to two guide rail frames 543 through the two sliding rods.

[0056] In practice, after the roller 52 pushes the adhesive to the end of the display screen, the operation of drive motor 3 550 and drive motor 1 24 is stopped, and drive motor 2 534 is started. Drive motor 2 534 drives the threaded rod 532 to rotate. The threaded rod 532 drives the corresponding ring plate 530 to move towards another ring plate 530 through the connecting plate. The clearance opening on the ring plate 530 can prevent the ring plate 530 from colliding with the end of the display screen. The moving ring plate 530 drives the corresponding side cleaning plate 531 to move and scrape off the adhesive at the end of the display screen. The scraped adhesive falls into the collection frame 41 by its own gravity until the moving side cleaning plate 531 contacts the fixed side cleaning plate 531. At this time, the moving side cleaning plate 531 will display. All the adhesive at the end of the screen is scraped off, effectively avoiding the step of operators cleaning the adhesive accumulated at the end of the display screen. The adhesive removal efficiency of the display screen is significantly improved. After the adhesive removal is completed, the display screen can be removed from the support plate 40. At the same time, the moving ring plate 530 drives the scraper 536 to move. The scraper 536 pushes the adhesive accumulated on the scraper strip 533. The scraper 536 has an inclined surface for pushing the adhesive. The scraper 536 separates the adhesive from the scraper strip 533 through the inclined surface and it falls into the collection frame 41. Then, the drive motor 534 drives the threaded rod 532 to rotate in the opposite direction. The threaded rod 532 drives the corresponding ring plate 530 to move the required distance. At this time, the distance between the two side cleaning plates 531 matches the length of the scraper plate 540. Then, the hydraulic push rod 541 is activated, which drives the sliding frame 542 to move. The sliding frame 542, through two guide rods 544, drives two sliding rods on the connecting plate 545 to move along the guide of the two guide rail frames 543. The connecting plate 545, through the feed rod 549, drives the scraper 540 to move between the two side cleaning plates 531 and clean the residual adhesive on the opposite surfaces of the two side cleaning plates 531. When the scraper 540 moves to the left end of the two side cleaning plates 531, the movement of the scraper 540 stops. The drive motor 534 drives the threaded rod 532 to rotate forward. The threaded rod 532 drives the corresponding ring plate 530 to move. The moving ring plate 530 drives the corresponding side cleaning plate 531 to move again. The moving side cleaning plate 531 first contacts the rear end of the scraper plate 540. The rear end of the scraper plate 540 removes adhesive from the scraping surface of the moving side cleaning plate 531 until the moving side cleaning plate 531 contacts the feed rod 549. Then, the moving side cleaning plate 531 continues to push the feed rod 549. The feed rod 549 drives the scraper plate 540 to move along the guide rod 547 and stretches the reset spring 548. The front end of the scraper plate 540 removes adhesive from the scraping surface of the fixed side cleaning plate 531 to prevent the adhesive on the side cleaning plate 531 from affecting subsequent work. The material passage notches at the lower ends of the two ring plates 530 are used for the scraper plate 540 to pass through, so as to avoid affecting the removal of adhesive from the side cleaning plate 531.

[0057] After the adhesive is removed from the two side cleaning plates 531, the second drive motor 534 drives the threaded rod 532 to rotate in the opposite direction. The threaded rod 532 drives the corresponding ring plate 530 to reset. At this time, the second return spring 548 in the stretched state resets and drives the feed rod 549 to reset. Then, the hydraulic push rod 541 drives the sliding frame 542 to reset. The sliding frame 542 drives the connecting plate 545 to reset through the two guide rods 544. The connecting plate 545 drives the scraper plate 540 to reset through the feed rod 549. The CNC module 30 controls the two lifting rods 31 to drive the support plate 501 to reset upward. The first drive motor 24 drives the transmission screw 23 to rotate in the opposite direction. The transmission screw 23 drives the moving plate 22 to move through the connecting protrusion. The moving plate 22 drives the cleaned display screen to reset through the support plate 40. The operator places the display screen that has not been de-adheded and repeats the steps of cleaning and de-adheding the display screen until all the display screens are completely de-adheded and cleaned. The cleaning of the display screen is then completed.
