Description

Technical Field

[0001] The present invention relates to the technical field of screen cleaning, in particular to a liquid crystal display screen component cleaning device. Background Art

[0002] Liquid crystal display is a type of flat panel display used for television and computer screen displays. Liquid crystal display uses a liquid crystal solution in two polarized materials. When electric current passes through the liquid, the crystals are rearranged to achieve the purpose of imaging.

[0003] During the LCD screen assembly or bonding process, if bubbles, foreign matter, or poor bonding are found, the OCA adhesive must be peeled off and re-bonded. In the multi-layer OCA bonding process, if a layer of adhesive has defects, the OCA adhesive must be removed and re-applied.

[0004] The existing technology usually adopts a rolling removal method to remove the OCA glue on the surface of the liquid crystal display screen. This glue removal method can push the OCA glue on the surface of the display screen out of the display screen through a silicone roller, thereby achieving the glue removal function. However, when the existing silicone roller pushes the OCA glue on the surface of the display screen, the OCA glue is not only accumulated and moved in the pushing direction after being subjected to force, but also accumulated and moved to both sides of the display screen, resulting in OCA glue residue on the cleaned display screen. At the same time, OCA glue may also remain on the surface of the silicone roller. After the silicone roller pushes the OCA glue out of the display screen, the OCA glue will remain at the end of the display screen, and the operator needs to manually remove the accumulated OCA glue or move the display screen to the next step to remove the end OCA glue. Therefore, multiple devices need to work together to remove the glue from the entire display screen, resulting in cumbersome display screen glue removal steps and low glue removal efficiency.

[0005] Therefore, there is an urgent need to provide a cleaning device that can improve the glue removal effect and efficiency of the liquid crystal display surface. Summary of the Invention

[0035] To make the above-mentioned objects, features, and advantages of the present invention more readily apparent, specific embodiments of the present invention are described in detail below with reference to the accompanying drawings. The following description sets forth numerous specific details to facilitate a full understanding of the present invention. However, the present invention can be implemented in many other ways than those described herein, and those skilled in the art may make similar modifications without departing from the scope of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0036] See Figure 1-Figure 3 A liquid crystal display screen component cleaning device includes a workbench 1, and the upper end of the workbench 1 is connected to a moving group 2 and a pressing group 3.

[0037] See Figure 1 and Figure 4 The moving group 2 includes two guide rods 20 symmetrically mounted on the upper end of the workbench 1 through a mounting seat, and a sliding block 21 is commonly sleeved and connected on the two guide rods 20. A moving plate 22 is commonly mounted on the two sliding blocks 21. A connecting protrusion is integrally formed in the middle of the lower end of the moving plate 22, and the connecting protrusion is threadedly connected to a transmission screw 23. The transmission screw 23 is rotatably connected to the mounting seat through a bearing, and the mounting seat is fixedly connected to the upper end of the workbench 1. The end of the transmission screw 23 is fixedly connected to a drive motor 24, and the drive motor 24 is fixedly connected to the upper end of the workbench 1 through a motor seat.

[0038] During specific operation, the workbench 1 is an 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, and the transmission screw 23 drives the movable plate 22 to move through the connecting protrusion, thereby realizing the function of moving the display screen. The two guide rods 20 guide the movement of the movable 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 receiving group 4, which is connected to the moving group 2 and is used to place the LCD screen. The receiving group 4 includes a supporting plate 40 connected to the moving group 2, the upper end of the moving plate 22 is fixedly connected to the supporting plate 40, and the left end of the supporting plate 40 is detachably connected to a collection frame 41.

[0040] See Figure 1 、 Figure 4 and Figure 5 The collection frame 41 is a U-shaped structure with an opening facing upward. A mounting bar 410 is integrally formed at the right end of the collection frame 41. The mounting bar 410 is fixedly connected to the support plate 40 by bolts. A baffle 411 is integrally formed at the upper end of the left side wall of the collection frame 41 in an inclined state.

[0041] See Figure 1 、 Figure 4 and Figure 5 The placing group 4 further includes a limiting strip 42 installed on the upper end surface of the supporting plate 40 , and the limiting strip 42 is located at the side of the upper end of the supporting plate 40 .

[0042] During specific work, after the workbench 1 is fixed, the mounting bar 410 at the right end of the collection frame 41 is moved to the lower end of the support plate 40, and then the mounting bar 410 is fixed to the lower end of the support plate 40 by 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 in the same plane as the upper end of the limit bar 42. Then, the display screen whose surface 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 close to the limit bar 42 and the side wall of the collection frame 41 respectively. The height of the upper end face 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 limit bar 42 to ensure that the colloid 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 numerical control module 30 installed on the upper end of the workbench 1, and two lifting rods 31 are connected to the numerical control module 30.

[0044] See Figure 1 、 Figure 6 and Figure 7 The LCD screen assembly cleaning device also includes a rolling cleaning group 5, which is connected to the pressing group 3 and is located above the supporting plate 40. The rolling cleaning group 5 includes a support part 50 connected to the pressing group 3, and the support part 50 includes two symmetrically distributed support rods 500 that are slidably connected to the upper end of the workbench 1. The upper ends of the two support rods 500 are jointly installed with a support plate 501, and 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 rod 500 is provided with a support spring 502 that is fixedly connected to the lower end of the support plate 501.

[0045] During specific 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, and the two support rods 500 are slidably connected to the workbench 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 has a buffering effect on the descent of the support plate 501 and a resetting effect on the rise of the support plate 501.

[0046] See Figure 1 、 Figure 6 and Figure 7 A connecting frame 51 with a U-shaped structure and an opening facing downward and a scraper portion 54 are installed at the lower end of the support plate 501. A rolling roller 52 is rotatably connected to the connecting frame 51, and a side cleaning portion 53 is connected to the rolling roller 52.

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

[0048] During specific operation, in the initial state, the driving motor 2 534 is connected to the external power supply, and the support plate 501 drives the rolling roller 52 to the highest position through the connecting frame 51. Then, according to the width of the display screen, the driving motor 2 534 is started, and the driving motor 2 534 drives the threaded rod 532 to rotate. The threaded rod 532 drives the corresponding ring plate 530 to move through the connecting plate, and the moving ring plate 530 drives the 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 rolling roller 52, and the scraping surface of the side cleaning plate 531 and the axis of the rolling roller 52 are in the same vertical plane.

[0050] See Figure 1 、 Figure 6 and Figure 7 The rolling cleaning group 5 also includes a driving part 55 for driving the rolling roller 52 to rotate. The driving part 55 includes a driving motor 3 550 installed on the support part 50. Two pulleys 551 are provided on one side of the driving motor 3 550. The two pulleys 551 are respectively installed on the output shaft of the driving motor 3 550 and the end of the rolling roller 52. A transmission belt 552 is commonly connected between the two pulleys 551.

[0051] During specific operation, in the initial state, the driving motor three 550 is connected to the external power supply. After the distance between the two side cleaning plates 531 is adjusted, the CNC module 30 controls the two lifting rods 31 to drive the support plate 501 to move downward, and the support plate 501 drives the rolling roller 52 to move downward through the connecting frame 51 until the lower end of the rolling roller 52 is in the same plane with the upper end surface of the display screen. At this time, the rolling roller 52 is located at the end of the display screen, and the rolling roller 52 drives the two ring plates 530 to descend. The two ring plates 530 respectively drive the two side cleaning plates 531 to move to both sides of the display screen, and the lower ends of the side cleaning plates 531 pass over the upper end surface of the display screen. Then, the driving motor three 550 and the driving motor one 24 are started at the same time. The driving motor three 550 drives the corresponding pulley 551 to rotate, and the pulley 551 drives another pulley 551 to rotate through the transmission belt 552, thereby driving the rolling roller 52 to rotate. The side cleaning plates 531 scrape the colloid on both sides of the display screen and limit the display screen while scraping the colloid on both sides of the display screen.

[0052] See Figure 7 The two ring plates 530 are both provided with a placement opening 535 for placing the scraping roller strip 533 , and the front end of the ring plate 530 located at the rear side is installed with a scraping block 536 located above the scraping roller strip 533 .

[0053] During specific operation, when the rolling roller 52 removes glue from the display screen, the scraping roller strip 533 scrapes off the glue remaining on the surface of the rolling roller 52 to avoid the glue sticking to the surface of the rolling roller 52 causing secondary adhesion to the display screen, thereby ensuring the glue removal effect of the rolling roller 52.

[0054] See Figure 6-Figure 8 The scraping part 54 includes a scraping plate 540 located on the right side of the rolling roller 52. The scraping plate 540 is used to remove the residual colloid on the side cleaning plate 531. The front end of the scraping plate 540 is in the same plane as the rear end surface of the front side cleaning plate 531.

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

[0056] During specific operation, after the rolling roller 52 pushes the glue to the end of the display screen, the driving motor 3 550 and the driving motor 1 24 are stopped, and the driving motor 2 534 is started again. The driving motor 2 534 drives the threaded rod 532 to rotate, and the threaded rod 532 drives the corresponding ring plate 530 to move toward the other ring plate 530 through the connecting plate. The avoidance 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 the glue at the end of the display screen. The scraped glue 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 The glue on the end of the screen is completely scraped off, which effectively avoids the operator having to go through the steps of clearing the colloid accumulated on the end of the display screen. The efficiency of display screen glue removal is significantly improved. After the display screen glue removal is completed, the display screen after glue removal can be removed from the supporting plate 40. At the same time, the moving ring plate 530 drives the scraper 536 to move, and the scraper 536 pushes the colloid accumulated on the scraper roller strip 533. The scraper block 536 pushes the colloid from the scraper roller strip 533 through the inclined surface and drops it into the collection frame 41. Then, the driving motor 2 534 drives the threaded rod 532 to rotate in the opposite direction, and the threaded rod 532 drives the corresponding ring plate 530 to move the required distance. At this time, the spacing between the two side cleaning plates 531 matches the length of the scraper plate 540. Then the hydraulic push rod 541 is started, and the hydraulic push rod 541 drives the sliding frame 542 to move. The sliding frame 542 drives the two slide bars on the connecting plate 545 to move along the guide of the two guide rail frames 543 through the two guide rods 1 544. The connecting plate 545 drives the scraper plate 540 to move between the two side cleaning plates 531 through the feed rod 549 and cleans the colloid remaining on the opposite surfaces of the two side cleaning plates 531. When the scraper plate 540 moves to the left end of the two side cleaning plates 531, the movement of the scraper plate 540 is stopped, and the driving motor 2 534 drives the threaded rod 532 to rotate forward, and 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, and the moving The movable side cleaning plate 531 first contacts the rear end of the scraper plate 540, and the rear end of the scraper plate 540 removes glue from the scraping surface of the movable side cleaning plate 531 until the movable side cleaning plate 531 contacts the feed rod 549. The movable side cleaning plate 531 continues to push the feed rod 549, and the feed rod 549 drives the scraper plate 540 to move along the guide of the guide rod 2 547 and stretches the return spring 2 548. The front end of the scraper plate 540 removes glue from the scraping surface of the fixed side cleaning plate 531 to avoid the colloid on the side cleaning plate 531 affecting the subsequent work. The feeding notch at the lower end of the two ring plates 530 is used for the scraper plate 540 to pass through to avoid affecting the glue removal of the side cleaning plate 531.

[0057] After the two side cleaning plates 531 have completed degumming, the driving motor 2 534 drives the threaded rod 532 to rotate in the opposite direction, and the threaded rod 532 drives the corresponding ring plate 530 to reset. At this time, the reset spring 2 548 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 1 544. 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 driving motor 1 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 supporting plate 40. The operator places the display screen that has not been degummed, and repeats the steps of display screen cleaning and degumming until all the display screens are completely degummed and cleaned.
