Description

Technical Field

[0001] This utility model relates to the field of LCD screen repair, and in particular to a dustproof and cleaning device for LCD screen repair. Background Technology

[0002] After LCD screen repair is completed, a protective film is usually applied to the screen surface to prevent scratches or secondary damage during transportation and use. However, the repair workshop environment often contains a large number of suspended dust particles, which easily adhere to the LCD screen surface during the film application process. If not thoroughly removed, this can lead to problems such as air bubbles, residual impurities, or even poor adhesion under the protective film, seriously affecting the quality of the film application and the display effect. Currently, the most common cleaning method relies on manual wiping with lint-free cloths and cleaning solutions. However, this method has low dust removal efficiency, especially in open repair stations where dust continuously settles, severely affecting the adhesion and quality of subsequent film application. At the same time, repeated cleaning operations also prolong repair time and reduce overall work efficiency.

[0003] Therefore, there is an urgent need for a specialized device that can effectively isolate dust interference and achieve efficient dust removal and wiping in one step, so as to ensure the surface cleanliness of the LCD screen before applying the film and improve the overall efficiency and quality of maintenance.

[0029] Please see Figures 1-4 A dustproof cleaning device for LCD screen repair includes a dustproof box 1. Preferably, the vertical cross-section of the dustproof box 1 is pentagonal, meaning the front side of the dustproof box 1 is composed of an inclined panel and a vertical panel. A viewing window 1.4 is provided on the inclined panel, and the viewing window 1.4 is made of transparent glass and embedded in the inclined panel of the dustproof box 1, facilitating the maintenance personnel to observe the condition inside the box. Flow strips 2 are fixedly installed on the left and right sides inside the dustproof box 1. The flow strips 2 include an outer frame fixed to the dustproof box 1 and rollers rotatably installed inside the outer frame. The dustproof box 1 has two mounting ports, I and II, on its front side. A placement drawer 3 and a dust collection drawer 4 are movably installed in mounting ports I and II, respectively, with the dust collection drawer 4 located below the placement drawer 3. The placement drawer 3 is used to hold the LCD screen. The bottom of the placement drawer 3 is made of a frame and a mesh, and its left and right sides can roll into contact with the flow strip 2, allowing the placement drawer 3 to be pulled out from mounting port I. When the placement drawer 3 is fully pushed into the dustproof box 1, the flow strip 2 provides support. The dustproof box 1 is equipped with a dust removal component and a cleaning component, used to blow away dust from the surface of the LCD screen and wipe away dust from its surface, respectively. The blown-off dust falls into the dust collection drawer 4 for collection.

[0030] As a preferred embodiment, please refer to Figures 6-8Referring to the dust removal assembly, it includes a blower duct 7, air nozzles 8, a knob 9, a retaining ring 10, a filter box 11, and a fan 12. The blower duct 7 is located on the top inside the dustproof box 1, with its two ends rotatably mounted to the left and right sides of the dustproof box 1. Multiple air nozzles 8 are connected to the blower duct 7. The fan 12 is fixedly installed on the left side outside the dustproof box 1, and its output end is connected to the right end of the blower duct 7. When the fan 12 is started, it blows air into the dustproof box 1 through the blower duct 7 and air nozzles 8 to blow away dust from the LCD screen.

[0031] More specifically, the right end of the blower pipe 7 is rotatably mounted to the right side of the dustproof box 1 via a sealed bearing; a second through hole is provided on the left side of the dustproof box 1, and a retaining ring 10 is fixedly embedded in the second through hole. The inner side of the retaining ring 10 is provided with a groove 10.1, which includes a number of grooves arranged at intervals along the circumference of the retaining ring 10, and each groove extends along the axial direction of the retaining ring 10; a knob 9 is fixedly sleeved on the left end of the blower pipe 7. The knob 9 includes an integrally formed sleeve 9.1 and a hand-turning part 9.3. The sleeve 9.1 is fixedly sleeved on the left end of the blower pipe 7, and a protrusion 9.2 extending along its axial direction is fixedly provided on the outer side of the sleeve 9.1. The protrusion 9.2 can be made of rubber material and its radial cross section is semi-circular. The sleeve 9.1 passes through the retaining ring 10, and the protrusion 9.2 is movably engaged with the groove. The hand-turning part 9.3 extends out of the dustproof box 1. By setting the knob 9 and the retaining ring 10, when the maintenance personnel hold the knob 9.3, the protrusion 9.2 can be engaged in one of the grooves, and drive the air nozzle 8 on the blower pipe 7 to blow air at a certain angle towards the LCD screen, so that the blower pipe 7 will not rotate randomly.

[0032] More specifically, a filter box 11 is fixedly installed on the left side of the dustproof box 1. A fan 12 is fixedly installed on the left side of the filter box 11, and its output end is connected to the filter box 11. A first through hole is opened on the left side of the dustproof box 1. The left end of the blower pipe 7 passes through the first through hole and is rotatably connected to the right side of the filter box 11 via a sealed bearing. A filter screen 11.1 is detachably installed on the filter box 11, and the filter screen 11.1 is arranged between the blower pipe 7 and the fan 12. The filter screen 11.1 filters and removes dust from the air coming from the outside, preventing external dust from being blown into the dustproof box 1.

[0033] As a preferred embodiment, please refer to Figure 9 Referring to the cleaning components, the cleaning components include a sponge box 13, a handle 14, and a cleaning sponge 15. The sponge box 13 can be moved back and forth and is horizontally installed above the storage drawer 3. The cleaning sponge 15 is fixedly installed on the side of the sponge box 13. During operation, the cleaning sponge 15 can press against the upper surface of the LCD screen and wipe away the dust on its surface.

[0034] More specifically, the dust box 1 has a main moving groove 1.2 and a secondary moving groove 1.3 on its left and right sides, respectively. The sponge box 13 has a left sliding rod 13.1 and a right sliding rod 13.2 fixedly installed on its left and right sides, respectively. The left sliding rod 13.1 can slide through the main moving groove 1.2, and its left end protrudes from the moving groove 1.2 and is fixedly installed with a handle 14. The right sliding rod 13.2 can slide into the secondary moving groove 1.3. The second curtain 17 is fixedly nailed to the left side of the inside of the dust box 1 above the main moving groove 1.2. The bottom of the second curtain 17 can extend slightly beyond the bottom of the main moving groove 1.2 and can be made of rubber material. After the dust removal component finishes blowing, the fan 12 is turned off. The maintenance personnel pull the handle 14 forward, which moves the sponge box 13 and the cleaning sponge 15 forward to wipe the LCD screen and remove dust. The second curtain 17 can prevent external dust from entering the box or dust from being blown out of the box and affecting the external working environment when the cleaning component is not working. It is also easier to collect the dust blown off the LCD screen. When the handle 14 is pulled, the second curtain 17 will flip up due to the influence of the left slide bar 13.1, which can keep the box closed as much as possible without affecting the forward and backward movement of the sponge box 13 and the cleaning sponge 15.

[0035] More specifically, a receiving chamber 1.1 extends horizontally outward from the rear interior of the dustproof box 1. The sponge box 13 and the cleaning sponge 15 can be completely contained within the receiving chamber 1.1. A first curtain 16 is fixedly nailed above the receiving chamber 1.1 on the rear interior of the dustproof box 1. The bottom of the first curtain 16 is flush with or slightly longer than the bottom of the receiving chamber 1.1. The first curtain 16 can be made of rubber. When the cleaning components are not in operation, the sponge box 13 and the cleaning sponge 15 are contained within the receiving chamber 1.1. The first curtain 16 prevents dust from entering the receiving chamber 1.1 during dust blowing operations, reducing dust contamination of the cleaning sponge 15 and affecting its cleaning power. When the cleaning components need to be used, the sponge box 13 and the cleaning sponge 15 move forward. Due to the deformable nature of the first curtain 16, it will flip upward, thus not affecting the forward and backward movement or storage of the sponge box 13 and the cleaning sponge 15.

[0036] More specifically, the sponge box 13 includes mounting slots symmetrically arranged on its upper and lower sides. The cleaning sponge 15 includes a thin cleaning sponge 15.1 and a thick cleaning sponge 15.2, which are respectively fixedly embedded in the two mounting slots. Since the thickness of the LCD screen varies, by providing two cleaning sponges 15 of different thicknesses, the appropriate thickness of the cleaning sponge 15 can be switched to wipe the LCD screen. Switching is simply a matter of holding the handle 14 and turning the knob.

[0037] For a preferred embodiment, please refer to Figure 2Inside the dustproof box 1, dustproof plates a5 and b6 are fixedly installed from top to bottom. These plates are spaced apart between the storage drawer 3 and the dust collection drawer 4. Both plates are inclined relative to the horizontal direction, and their vertical projections overlap. When the dust removal assembly blows dust off the LCD screen, the blown-off dust is guided by the airflow through the plates a5 and b6, and is blown into the dust collection drawer 4 in a zigzag pattern. This combination prevents the dust collected in the dust collection drawer 4 from being blown back by the airflow, ensuring efficient dust collection.

[0038] The method of using this utility model is as follows: First, pull out the placement drawer 3, place the LCD screen inside, and then push it completely into the dustproof box 1. Then, start the fan 12. The fan 12 can blow air into the dustproof box 1 through the air pipe 7 and the air nozzle 8 to blow away the dust on the LCD screen. Turn off the fan 12 to stop blowing air. The maintenance personnel pull the handle 14 forward to move the sponge box 13 and the cleaning sponge 15 forward, so that the cleaning sponge 15 presses against the LCD screen to wipe it and remove dust. After the LCD screen is cleaned, the placement drawer 3 can be slowly pulled out, and at the same time, the screen protector can be applied to the LCD screen, which greatly improves the quality of the screen protector application. After a period of time, when the dust in the dust collection drawer 4 has accumulated to a certain extent, it can be pulled out for cleaning.
