Description

Technical Field

[0001] This utility model relates to the field of screen coating technology, and in particular to an anti-glare screen component coating device. Background Technology

[0002] The main functions of anti-glare screen component coating equipment are as follows: By covering the surface of the anti-glare screen component with a protective film, it can effectively prevent the screen from being scratched, worn, stained with fingerprints, dust, and corroded by chemicals, thereby extending the screen's lifespan and maintaining its good performance and appearance. This type of equipment can achieve automated or semi-automated coating operations. Compared with manual coating, it has higher coating accuracy and efficiency, can ensure the consistency of coating quality, and reduces errors and defects caused by manual operation. It is suitable for enterprises that produce anti-glare screen components on a large scale, and helps to improve production efficiency and product quality stability.

[0003] However, existing technologies, such as Chinese Publication No. CN217834729U, "A Fully Automatic Mobile Phone Screen Coating Device," provide a fully automatic mobile phone screen coating device. This device includes a base, a height adjustment mechanism, a positioning mechanism, and a coating mechanism. The height adjustment mechanism, comprising a telescopic rod and a support plate, is connected to the base. The support plate is fixedly connected to the upper surface of the base via two symmetrically arranged telescopic rods, and the positioning mechanism is connected to the support plate. This fully automatic mobile phone screen coating device, during use, allows the height of the support plate to be adjusted according to the operator's height through the height adjustment mechanism, improving the device's applicability. The positioning and coating mechanisms first position the mobile phone and screen protector, then automatically apply the screen protector, resulting in more precise coating and improved efficiency.

[0004] However, this device lacks a retractable cleaning blade structure, which prevents the cleaning blade from being adjusted according to the thickness of the screen components to accommodate screens of various sizes and thicknesses. It also fails to accurately conform to the screen edges for cleaning, compromising the device's versatility and flexibility. Furthermore, the device lacks a quick workflow switching structure, which prevents the device from rapidly applying the film to the cleaned screen, increasing downtime for adjustments and reducing production efficiency.

[0025] Please see Figures 1 to 5 This utility model provides a technical solution: an anti-glare screen component coating device, including a movable plate 1, a housing 2 fixedly connected to the bottom of the movable plate 1, a telescopic shell 3 movably embedded in the inner surface of the housing 2, a scraper 4 fixedly connected to the bottom of the telescopic shell 3, a liner 5 fixedly connected to the inner surface of the housing 2, a lead screw 6 rotatably connected inside the liner 5, an internal thread block 7 threadedly connected to the outer surface of the lead screw 6, and fixed plates 8 fixedly connected to both sides of the internal thread block 7.

The internal thread block 7 is fixed inside the telescopic shell 3 by the fixed plates 8, so rotating the thread will cause the telescopic shell 3 to extend and retract inside the housing 2, and cause the scraper 4 to contact the top of the screen.

[0026] like Figures 1 to 5 As shown, a power rod 11 is fixedly connected to one side of the drive bevel gear 10. The outer surface of the power rod 11 is rotatably connected to one side of the housing 2. A knob 12 is fixedly connected to the end of the power rod 11 away from the drive bevel gear 10. The knob 12 drives the power rod 11 to rotate on one side of the housing 2.

[0027] like Figures 1 to 5As shown, a limiting sleeve 13 is fixedly connected to one end of the movable plate 1. A limiting rod 14 is movably embedded in the inner surface of the limiting sleeve 13. A worktable 15 is fixedly connected to both ends of the limiting rod 14. The limiting sleeve 13 at the other end of the movable plate 1 can only move along the axial direction of the limiting rod 14.

[0028] like Figures 1 to 5 As shown, the end of the movable plate 1 away from the limiting sleeve 13 is fixedly connected to an internal threaded sleeve 16. The inner surface of the internal threaded sleeve 16 is threadedly connected to a threaded rod 17. The outer surface of the threaded rod 17 is rotatably connected to the inside of the worktable 15 and extends out one end. Rotating the thread will drive the internal threaded sleeve 16.

[0029] like Figures 1 to 5 As shown, a mounting sleeve 18 is fixedly connected to one side of the workbench 15. A first motor 19 is fixedly embedded on the inner surface of the mounting sleeve 18. The output end of the first motor 19 is fixedly connected to one end of the threaded rod 17. When the first motor 19 is powered on, it will drive the threaded rod 17 to rotate, and the thread will drive the inner threaded sleeve 16.

[0030] like Figures 1 to 5 As shown, a pressure plate 20 is fixedly connected to the bottom of the workbench 15, and a laminating machine 21 is fixedly connected to the top of the workbench 15. The laminating machine 21, as a prior art, can accurately cover the screen assembly with the adsorbed protective film.

[0031] like Figures 1 to 5 As shown, a rotating rod 22 is rotatably connected to the bottom of the workbench 15, and an intermittent rotating wheel 23 is fixedly connected to the bottom of the rotating rod 22. Multiple force grooves 24 are opened on one side of the intermittent rotating wheel 23, and force-applying rods 25 are installed inside the force grooves 24. The force-applying rods 25 will drive the intermittent rotating wheel 23 to rotate under the action of the force grooves 24 opened on the intermittent rotating wheel 23.

[0032] like Figures 1 to 5 As shown, a crank 26 is fixedly connected to the bottom of the force-applying rod 25, a second motor 27 is fixedly connected to the bottom of the crank 26, the bottom of the second motor 27 is fixedly connected to the top of the pressure plate 20, a turntable 28 is fixedly connected to the top of the rotating rod 22, and a positioning rod 29 is fixedly connected to the top of the turntable 28. When the second motor 27 is powered on, it will drive the crank 26 and the force-applying rod 25 to rotate.

[0033] Working principle: First, place the device to be coated above the turntable 28 and inside the positioning rod 29. Then, drive the power rod 11 to rotate on one side of the housing 2 by turning the knob 12. The driving bevel gear 10, which rotates with the power rod 11, will drive the lead screw 6 to rotate inside the liner 5 under the meshing action of the driven bevel gear 9. The rotating thread will drive the internal thread block 7. The internal thread block 7 is fixed inside the telescopic housing 3 by the fixing plate 8. Therefore, the rotating thread will drive the telescopic housing 3 to extend and retract inside the housing 2, so that the scraper 4 contacts the top of the screen. Then, start the external power supply of the first motor 19. The first motor 19 is fixed to one side of the worktable 15 by the mounting sleeve 18. After the first motor 19 is powered on, it will drive the threaded rod 17 to rotate. The thread will drive the internal thread sleeve 16, and the limit at the other end of the moving plate 1. The sleeve 13 can only move along the axis of the limiting rod 14, so the rotating thread will drive the scraper 4 to move along the axis of the limiting rod 14 and clean the surface of the screen. Then, the external power supply of the second motor 27 on the top of the pressure plate 20 is turned on. After the second motor 27 is powered on, it will drive the crank 26 and the force rod 25 to rotate. Under the action of the force groove 24 opened on the intermittent rotating wheel 23, the force rod 25 will drive the intermittent rotating wheel 23 to rotate. For every one rotation of the force rod 25, the intermittent rotating wheel 23 and the rotating rod 22 will rotate a quarter rotation. When the force rod 25 rotates twice, the intermittent rotating wheel 23 will rotate half a rotation, so that the screen is located under the laminating machine 21. The laminating machine 21, as a prior art, can accurately cover the screen assembly with the adsorbed protective film.
