Description

Technical Field

[0001] This application relates to the field of cleaning and dust removal technology, and in particular to a surface cleaning mechanism. Background Technology

[0002] The production process of Micro LED display panels requires a high cleanliness level (Class 10 to Class 100). Before the Micro LED display panel is tested for illumination, its surface must be cleaned to prevent dust particles from affecting the test results. If the display panel surface is covered in dust, it will affect the test results of the testing equipment, leading to inaccurate testing and increased costs.

[0003] In existing technologies, dust removal devices are installed on conveyor belts. These devices are generally stationary, while the back of the display panel is a shell structure placed on the conveyor belt. The back of the display panel does not require cleaning or dust removal. The front of the display panel is placed facing upwards, and the dust removal device cleans the front of the LCD screen using the conveyor belt's transport power.

[0004] The dust removal device uses cleaning brushes to clean the display panel. After a period of use, this dust removal device needs to be shut down and manually disassembled and cleaned.

[0027] The beneficial effects of the technical solution provided in this application include:

[0028] This application provides a cleaning mechanism. The cleaning mechanism includes a blowing and adsorption mechanism, which comprises a blowing and dust-collecting hood. The blowing and dust-collecting hood has a hollow structure and a dust-collecting port at the bottom. Inside the blowing and dust-collecting hood is an air knife with the air outlet facing the dust-collecting port. A vacuum adsorption interface is provided at the end of the blowing and dust-collecting hood away from the dust-collecting port. A height adjustment structure is also provided, including a mounting plate. A height adjustment plate for fixing the blowing and adsorption mechanism is connected to the mounting plate. The mounting plate is provided with a vertical adjustment mechanism for adjusting the vertical movement of the height adjustment plate.

[0029] Therefore, the cleaning mechanism of this application utilizes a blowing and adsorption mechanism and a height adjustment structure in conjunction to clean the surface of the display panel. The blowing and adsorption mechanism includes a blowing and suction hood, inside which is an air knife that performs high-pressure blowing on the display panel surface. The air nozzle of the air knife faces the suction port of the blowing and suction hood. Dust blown away by the air knife is not only covered by the blowing and suction hood, but also adsorbed into a designated area using a vacuum adsorption interface, preventing the cleaned display panel from being contaminated again. This blowing and adsorption mechanism requires no downtime for cleaning, can be reused for extended periods, and prevents dust from spreading, thus improving the cleanliness level of the production workshop.

[0030] The cleaning mechanism of this application utilizes a height adjustment structure to adjust the distance between the blowing and adsorption mechanism and the display panel. By adjusting this distance, cleaning operations can be performed on display panels of different thicknesses. The height adjustment structure includes a height adjustment plate connected to the blowing and adsorption mechanism. A vertical adjustment mechanism on the mounting plate allows the height adjustment plate to move up and down vertically. This vertical adjustment mechanism can be automatic or manual. When the vertical adjustment mechanism moves the blowing and adsorption mechanism closer to the display panel, it enhances the blowing force of the mechanism, improving cleaning efficiency.

[0031] The cleaning mechanism of this application includes an air knife inlet chamber and an air knife outlet chamber connected to each other. Both the air knife inlet chamber and the air knife outlet chamber are hollow structures that run vertically through each other. The air knife inlet chamber has an air knife mounting base for introducing compressed gas, and the air knife mounting base has an air inlet channel communicating with the air knife. The air knife is fixed in the air knife outlet chamber, and the air knife's nozzle is recessed into the bottom opening of the air knife outlet chamber. The air knife mounting base in the air knife inlet chamber is used to connect compressed air and provide high-pressure gas to the air knife. The air knife outlet chamber is used to contain the air knife, and the gas blown out by the air knife and the dust swept away are both covered by the air knife inlet chamber and the air knife outlet chamber.

[0032] The cross-sections of the air knife air inlet chamber and the air knife air outlet chamber of the cleaning mechanism of the present application are both rectangular box structures. An air inlet joint is connected to the outside of the air knife air inlet chamber. The air knife mounting seat includes an air inlet connecting block communicating with the air inlet joint and an air knife fitting block. The air inlet connecting block is located at the top of the air knife fitting block and is connected to form a "convex" structure. The air inlet passage includes a horizontal passage located in the air inlet connecting block and communicating with the air inlet joint, and a vertical passage communicating with the horizontal passage and located in the air inlet connecting block and the air knife fitting block. The cross-sections of the air knife air inlet chamber and the air knife air outlet chamber are both rectangular box structures for accommodating the air knife mounting seat and the air knife respectively. The air inlet connecting block of the air knife mounting seat communicates with the air inlet joint, and the air knife fitting block of the air knife mounting seat communicates with the air knife, so that the high-pressure gas connected to the air inlet joint enters the horizontal passage of the air inlet connecting block, and then enters the vertical passage communicating with the horizontal passage and located in the air inlet connecting block and the air knife fitting block, and finally enters the air knife.

[0033] The air inlet connecting block of the cleaning mechanism of the present application is an isosceles trapezoid structure and is connected to the large surface parallel to the air knife air inlet chamber in the middle of the air knife air inlet chamber. The air knife fitting block is a long strip structure and is connected to the small surface parallel to the air knife air inlet chamber in the middle of the air knife air inlet chamber. Two symmetrically arranged upper adsorption channels are formed between the two sides of the air inlet connecting block and the small surface of the air knife air inlet chamber, and two symmetrically arranged lower adsorption channels are formed between the air knife fitting block and the large surface of the air knife air inlet chamber. The air inlet connecting block is connected to the large surface parallel to the air knife air inlet chamber, and the air knife fitting block is connected to the small surface parallel to the air knife air inlet chamber, so that two symmetrically arranged upper adsorption channels are formed between the two sides of the air inlet connecting block and the small surface of the air knife air inlet chamber, and two symmetrically arranged lower adsorption channels are formed between the air knife fitting block and the large surface of the air knife air inlet chamber. The upper adsorption channel and the lower adsorption channel are interconnected to adsorb the swept dust to the vacuum adsorption interface for discharge.

[0034] The air knife of the cleaning mechanism of the present application is a long strip structure. The top surface of the air knife is the air inlet end, and the bottom surface of the air knife is the air blowing end. The air inlet end is in mutual contact with the bottom surface of the air knife fitting block. An air inlet hole communicating with the vertical passage is provided in the middle of the air inlet end of the air knife, and a slit penetrating the air inlet end and the air blowing end is provided on the air knife, and the slit extends along the length direction of the air knife. The air knife adopts a long strip structure, so that the air knife has a wider coverage area when dust-removing and cleaning the surface of the display panel. The air inlet end of the air knife is in mutual contact with the bottom surface of the air knife fitting block, so that the slit of the air knife only blows the high-pressure gas towards the dust suction port. The width of the slit is narrow and extends along the length direction of the air knife to increase the blowing pressure of the high-pressure gas and quickly remove stubborn stains on the surface of the display panel.

[0035] The air knife of this cleaning mechanism is located in the middle of the air knife outlet chamber and connected to a small surface parallel to the air knife outlet chamber. Two symmetrically arranged bottom adsorption channels are formed between the air knife and the large surface of the air knife outlet chamber. The length direction of the air knife is parallel to the length direction of the air knife outlet chamber, and both ends of the air knife are fixed to two parallel small surfaces on the inner wall of the air knife outlet chamber. The two symmetrically arranged bottom adsorption channels between the air knife and the large surface of the air knife outlet chamber are interconnected with the upper and lower adsorption channels to adsorb the swept dust to the vacuum adsorption interface for discharge.

[0036] The cleaning mechanism of this application includes a top cover plate connected to the top of the air knife inlet chamber for sealing the top opening of the air knife inlet chamber, with a vacuum adsorption interface connected to the top cover plate; and an airflow stabilizing plate connected to the bottom of the air knife outlet chamber for distributing and stabilizing airflow. The airflow stabilizing plate has a rectangular frame structure and contains multiple parallel and spaced guide vanes. The top cover plate not only seals the top opening of the air knife inlet chamber but also connects to the vacuum adsorption interface. The vacuum adsorption interface is located far from the slit of the air knife, preventing the compressed gas blown out by the air knife from being directly sucked away by the vacuum adsorption interface, thus improving the utilization rate of compressed air. The multiple parallel and spaced guide vanes within the airflow stabilizing plate guide and divide the compressed gas blown out by the air knife, allowing the divided airflow to clean each area separately.

[0037] The cleaning mechanism of this application has a mounting plate with threaded holes for connecting a height adjustment plate. The height adjustment plate has an elongated hole that matches the threaded holes, with the length of the elongated hole parallel to the vertical movement direction of the height adjustment plate. The mounting plate and the height adjustment plate are connected by bolts. The mounting plate has threaded holes for connecting the height adjustment plate, and the height adjustment plate has an elongated hole that matches the threaded holes. The height adjustment plate can be adjusted relative to the mounting plate through the elongated hole.

[0038] The vertical adjustment mechanism of the cleaning system of this application includes a fixed block fixed to the top of a mounting plate, an adjusting screw rotatably connected to the fixed block and threadedly connected to a height adjustment plate; and a top block fixed to the height adjustment plate, with a longitudinal micrometer knob fixedly connected to the bottom of the top block on the mounting plate. The adjusting screw is rotatably connected to the fixed block and threadedly connected to the height adjustment plate. The adjusting screw is used for coarse vertical adjustment of the height adjustment plate, and the longitudinal micrometer knob is used for fine vertical adjustment of the height adjustment plate.

[0053] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0054] This application provides a cleaning mechanism that solves the problem in related technologies where dust removal devices need to be shut down after a period of use, requiring manual disassembly and cleaning, and dust is scattered everywhere, which has an adverse effect on production workshops with high cleanliness levels.

[0055] See Figures 1 to 3 and Figure 10 As shown, this application embodiment provides a surface cleaning mechanism for a display panel, including:

[0056] The blowing and adsorption mechanism 100 includes a blowing and dust-collecting hood 110, which is a hollow structure with a dust-collecting port 111 at the bottom. Inside the blowing and dust-collecting hood 110, there is an air knife 120 with its air nozzle facing the dust-collecting port 111. At the end of the blowing and dust-collecting hood 110 away from the dust-collecting port 111, there is a vacuum adsorption interface 151. The air knife 120 uses high-pressure gas to blow and clean the dust on the surface of the display panel. The blowing and dust-collecting hood 110 covers the blown-out dust in its inner cavity to prevent it from scattering, and the dust is adsorbed to a designated area for processing through the vacuum adsorption interface 151.

[0057] The height adjustment structure 200 includes a mounting plate 210, on which a height adjustment plate 220 for fixing the blowing and suction mechanism 100 is connected. The mounting plate 210 is provided with a vertical adjustment mechanism 230 for adjusting the vertical movement of the height adjustment plate 220. The vertical adjustment mechanism 230 is used to adjust the vertical height of the height adjustment plate 220 on the mounting plate 210, thereby adjusting the vertical height between the suction port 111 of the blowing and suction hood 110 and the display panel.

[0058] The surface cleaning mechanism for display panels in this embodiment utilizes a blowing and adsorption mechanism 100 and a height adjustment structure 200 in cooperation to clean the surface of the display panel. The blowing and adsorption mechanism 100 is equipped with a blowing and suction hood 110, and an air knife 120 is provided inside the blowing and suction hood 110 to perform high-pressure blowing on the surface of the display panel. The air outlet of the air knife 120 faces the suction port 111 of the blowing and suction hood 110.

[0059] The dust blown away by the air knife 120 is not only covered by the blowing and suction hood 110, but also collected in a designated area by the vacuum suction interface 151, preventing the cleaned display panel from being contaminated by dust again. This blowing and suction mechanism 100 does not require downtime for cleaning, can be reused for a long time, and prevents dust from spreading, thus improving the cleanliness level of the production workshop.

[0060] This application provides a surface cleaning mechanism for Micro LED display panels with cleanliness levels ranging from Class 10 to Class 100. This mechanism is fixed above the moving path of the Micro LED display panel, and the panel is cleaned as it slowly passes through it. The cleaning mechanism is versatile and can be used to clean Micro LED display panels of a certain size range; only the distance between the cleaning mechanism and the upper surface of the Micro LED display panel needs to be adjusted.

[0061] It should be noted that the cleaning system provided in this application is applicable not only to Micro LED production lines, but also to OLED panels, LCD panels, wafer inspection, integrated circuit manufacturing, chip manufacturing and other fields. This application does not limit its application to these fields.

[0062] The surface cleaning mechanism for display panels in this embodiment utilizes a height adjustment structure 200 to adjust the distance between the blowing and adsorption mechanism 100 and the display panel. By adjusting the distance between the blowing and adsorption mechanism 100 and the display panel, cleaning operations can be performed on display panels of different thicknesses. The height adjustment structure 200 is provided with a height adjustment plate 220 connected to the blowing and adsorption mechanism 100.

[0063] The mounting plate 210 is equipped with a vertical adjustment mechanism 230 that allows the height adjustment plate 220 to move up and down in the vertical direction. The vertical adjustment mechanism 230 can be adjusted automatically or manually. When the vertical adjustment mechanism 230 moves the blowing and adsorption mechanism 100 toward the display panel, it can enhance the blowing force of the blowing and adsorption mechanism 100 and improve the cleaning efficiency.

[0064] The blowing and adsorption mechanism 100 in this embodiment uses compressed gas blown out by the air knife 120 to blow away dust from the surface of the display panel. The blown exhaust gas and dust are then adsorbed into a designated area for collection through the vacuum adsorption interface 151 on the blowing and dust suction hood 110. Furthermore, this application does not use an ultrasonic generator to blow away dust particles via ultrasonic vibration, thus avoiding damage to electronic components on the circuit board of the display panel caused by the ultrasonic generator vibrating.

[0065] In some alternative embodiments: see Figures 2 to 7 As shown in the figure, this application embodiment provides a surface cleaning mechanism for a display panel. The blowing and dust extraction hood of the surface cleaning mechanism includes an air knife inlet chamber 130 and an air knife outlet chamber 140 connected to each other. Both the air knife inlet chamber 130 and the air knife outlet chamber 140 are hollow structures that extend vertically. The air knife inlet chamber 130 is provided with an air knife mounting base for introducing compressed gas, and the air knife mounting base has an air inlet channel communicating with the air knife 120. The air knife 120 is fixed in the air knife outlet chamber 140, and the air outlet of the air knife 120 is recessed into the bottom opening of the air knife outlet chamber 140.

[0066] The air nozzle of the air knife 120 is recessed within the bottom opening of the air knife outlet chamber 140, so that the compressed gas blown out from the air nozzle of the air knife 120 is covered by the dust extraction hood 110, preventing the compressed gas from carrying dust out of the dust extraction hood 110 and causing environmental pollution. The air nozzle of the air knife 120 is located inside the dust extraction hood 110 and directly above the dust extraction port of the dust extraction hood 110, so that a cleaning chamber that can both blow out compressed gas and absorb dust and exhaust gas is formed between the dust extraction port 111 of the dust extraction hood 110 and the air nozzle of the air knife 120.

[0067] In this embodiment, both the air knife inlet chamber 130 and the air knife outlet chamber 140 are hollow structures that extend vertically. These hollow structures not only cover dust but also accommodate the air knife mounting base and the air knife 120. The air knife mounting base within the air knife inlet chamber 130 is used to connect compressed air and provide high-pressure gas to the air knife 120. The air knife outlet chamber 140 is used to accommodate the air knife 120. The gas blown out by the air knife 120 and the dust swept away are covered by the air knife inlet chamber 130 and the air knife outlet chamber 140, preventing the gas and dust blown out by the air knife 120 from escaping outside the blowing and dust extraction hood 110.

[0068] The air knife mounting seat and the air knife 120 are respectively fixed inside the air knife air inlet chamber 130 and the air knife air outlet chamber 140, forming a chamber for covering and vacuum - adsorbing dust and waste gas between the purging and dust - suction hood 110 and the air knife 120. Moreover, the space volume of this chamber can be larger, improving the dust - removing and adsorption efficiency on the surface of the display panel. There is no need to separately set up a vacuum - adsorption chamber inside the purging and dust - suction hood 110, simplifying the structure of the purging and adsorption mechanism 100, facilitating processing and assembly, and reducing production costs. In some alternative embodiments: Refer to Figures 2 to 7 As shown, the embodiment of the present application provides a surface cleaning mechanism for a display panel. The cross - sections of the air knife air inlet chamber 130 and the air knife air outlet chamber 140 of this surface cleaning mechanism are both rectangular box structures. An air inlet joint 133 is connected to the outside of the air knife air inlet chamber 130; the air knife mounting seat includes an air inlet connection block 131 communicating with the air inlet joint 133 and an air knife fitting block 132. The air inlet connection block 131 is located at the top of the air knife fitting block 132 and they are connected to form a "convex" - shaped structure.

[0069] The air inlet passage includes a horizontal passage 134 located inside the air inlet connection block 131 and communicating with the air inlet joint 133, and a vertical passage 135 communicating with the horizontal passage 134 and located inside the air inlet connection block 131 and the air knife fitting block 132. The cross - sections of the air knife air inlet chamber 130 and the air knife air outlet chamber 140 are both rectangular box structures, used to accommodate the air knife mounting seat and the air knife 120 respectively. The lengths of the air knife air inlet chamber 130 and the air knife air outlet chamber 140 are greater than the width of the display panel, so as to clean the surface when the display panel moves.

[0070] The air inlet connection block 131 of the air knife mounting seat is connected to the air inlet joint 133, and the air knife fitting block 132 of the air knife mounting seat is connected to the air knife 120. Thus, the high - pressure gas connected by the air inlet joint 133 enters the horizontal passage 134 of the air inlet connection block 131 in sequence, and then enters the vertical passage 135 communicating with the horizontal passage 134 and located inside the air inlet connection block 131 and the air knife fitting block 132, and finally enters the air knife 120.

[0071] In some alternative embodiments: Refer to Figures 2 to 7 As shown, the embodiment of the present application provides a surface cleaning mechanism for a display panel. The air inlet connection block 131 of this surface cleaning mechanism is an isosceles trapezoid structure and is connected to the large surface parallel to the air knife air inlet chamber 130 in the middle of the air knife air inlet chamber 130. The air knife fitting block 132 is a long - strip structure and is connected to the small surface parallel to the air knife air inlet chamber 130 in the middle of the air knife air inlet chamber 130.

[0072] Two symmetrically arranged upper adsorption channels 136 are formed between the two sides of the air inlet connecting block 131 and the small surface of the air knife inlet chamber 130, and two symmetrically arranged lower adsorption channels 137 are formed between the air knife bonding block 132 and the large surface of the air knife inlet chamber 130. The small surface of the air knife inlet chamber 130 is the side wall with a smaller inner wall area, and the large surface of the air knife inlet chamber 130 is the side wall with a larger inner wall area.

[0073] In this embodiment, the air inlet connecting block 131 is connected to the large surface of the air knife inlet chamber 130, which is parallel to each other, and the air knife fitting block 132 is connected to the small surface of the air knife inlet chamber 130, which is parallel to each other. This creates two symmetrically arranged upper adsorption channels 136 between the two sides of the air inlet connecting block 131 and the small surface of the air knife inlet chamber 130, and two symmetrically arranged lower adsorption channels 137 between the air knife fitting block 132 and the large surface of the air knife inlet chamber 130. The upper adsorption channels 136 and lower adsorption channels 137 are interconnected to adsorb the swept dust to the vacuum adsorption interface 151 for discharge.

[0074] In some alternative embodiments: see Figures 2 to 7 As shown in the figure, this application embodiment provides a surface cleaning mechanism for a display panel. The air knife 120 of the surface cleaning mechanism has an elongated structure. The top surface of the air knife 120 is the air inlet end 122, and the bottom surface of the air knife 120 is the air blowing end 123. The air inlet end 122 is in contact with the bottom surface of the air knife bonding block 132. The air inlet end 122 of the air knife 120 has an air inlet hole 121 in the middle that communicates with the vertical channel 135. A slit 124 is opened on the air knife 120, penetrating the air inlet end 122 and the air blowing end 123. The slit 124 extends along the length direction of the air knife 120.

[0075] The air knife 120 in this embodiment adopts a long strip structure, which allows for a wider coverage area when cleaning the surface of the display panel. The air inlet 122 of the air knife 120 is in contact with the bottom surface of the air knife bonding block 132, so that the slit 124 of the air knife 120 blows high-pressure gas only towards the dust suction port 111. The slit 124 is narrow and extends along the length of the air knife 120 to increase the blowing pressure of the high-pressure gas, quickly removing stubborn stains from the surface of the display panel.

[0076] In some alternative embodiments: see Figures 2 to 7As shown, this application embodiment provides a surface cleaning mechanism for a display panel. The air knife 120 of this surface cleaning mechanism is located in the middle of the air knife outlet chamber 140 and connected to a small surface parallel to the air knife outlet chamber 140. Two symmetrically arranged bottom adsorption channels 141 are formed between the air knife 120 and the large surface of the air knife outlet chamber 140. The small surface of the air knife outlet chamber 140 is a side wall with a smaller inner wall area, and the large surface of the air knife outlet chamber 140 is a side wall with a larger inner wall area.

[0077] In this embodiment, the length direction of the air knife 120 is parallel to the length direction of the air knife outlet chamber 140, and both ends of the air knife 120 are fixed to two parallel small surfaces on the inner wall of the air knife outlet chamber 140. Two symmetrically arranged bottom adsorption channels 141 are formed between the air knife 120 and the large surface of the air knife outlet chamber 140. The bottom adsorption channels 141 are interconnected with the upper adsorption channel 136 and the lower adsorption channel 137, and are used to jointly adsorb the swept dust to the vacuum adsorption interface 151 for discharge.

[0078] In some alternative embodiments: see Figures 1 to 3 , Figure 8 and Figure 9 As shown, this application embodiment provides a surface cleaning mechanism for a display panel. The blowing and dust suction hood 110 of the surface cleaning mechanism also includes an upper cover plate 150 connected to the top of the air knife inlet chamber 130 for sealing the top opening of the air knife inlet chamber 130, and a vacuum adsorption interface 151 connected to the upper cover plate 150. Additionally, an airflow stabilizing plate 160 is connected to the bottom of the air knife outlet chamber 140 for distributing and stabilizing airflow. The airflow stabilizing plate 160 has a rectangular frame structure, and multiple parallel and spaced guide vanes 161 are provided inside the airflow stabilizing plate 160.

[0079] In this embodiment, the top cover 150 not only seals the top opening of the air inlet chamber 130 of the air knife, but also connects to the vacuum adsorption interface 151. The vacuum adsorption interface 151 is far from the slit 124 of the air knife 120, preventing the compressed gas blown out by the air knife 120 from being directly sucked away by the vacuum adsorption interface 151, thus improving the utilization rate of compressed air. Multiple parallel and spaced guide vanes 161 within the airflow stabilizing plate 160 guide and divide the compressed gas blown out by the air knife 120, allowing the divided airflow to purge each area separately.

[0080] A flexible steel wire hose 152 is connected to the vacuum adsorption interface 151. One end of the flexible steel wire hose 152 is connected to the vacuum adsorption interface 151 via a stainless steel hose clamp 153, and the other end of the flexible steel wire hose 152 is connected to a vacuum pump. The vacuum pump is used to generate a vacuum source, and the negative pressure generated by the vacuum source adsorbs dust inside the blow-and-suction hood 110. The blow-and-suction hood 110 is relatively small in size, and placing the vacuum adsorption interface 151 at the top of the blow-and-suction hood 110 facilitates the arrangement and installation of the larger inner diameter flexible steel wire hose 152, thereby improving the adsorption efficiency of exhaust gas and dust.

[0081] In some alternative embodiments: see Figures 1 to 3 and Figure 10 As shown in the figure, this application embodiment provides a surface cleaning mechanism for a display panel. The mounting plate 210 of this surface cleaning mechanism has a threaded hole for connecting to a height adjustment plate 220. The height adjustment plate 220 has an elongated hole 221 adapted to the threaded hole, and the length direction of the elongated hole 221 is parallel to the vertical movement direction of the height adjustment plate 220. The mounting plate 210 and the height adjustment plate 220 are connected by bolts. The height adjustment plate 220 can adjust its height relative to the mounting plate 210 through the elongated hole 221.

[0082] The vertical adjustment mechanism 230 for the surface cleaning mechanism of the display panel in this embodiment includes a fixing block 231 fixed to the top of the mounting plate 210, an adjusting screw 232 rotatably connected to the fixing block 231 and threadedly connected to the height adjustment plate 220, and a top block 233 fixed to the height adjustment plate 220. A vertical micrometer knob 234 located at the bottom of the top block 233 is fixedly connected to the mounting plate 210. The adjusting screw 232 is rotatably connected to the fixing block 231 and threadedly connected to the height adjustment plate 220. The adjusting screw 232 is used for coarse vertical adjustment of the height of the height adjustment plate 220, and the vertical micrometer knob 234 is used for fine vertical adjustment of the height of the height adjustment plate 220.

[0083] Working principle

[0084] This application provides a surface cleaning mechanism for a display panel. The surface cleaning mechanism for a display panel includes a blowing and suction mechanism 100. This blowing and suction mechanism 100 includes a blowing and suction hood 110, which is a hollow structure with a suction port 111 at the bottom. Inside the blowing and suction hood 110, there is an air knife 120 with its air outlet facing the suction port 111. At one end of the blowing and suction hood 110 away from the suction port 111, there is a vacuum suction interface 151. A height adjustment structure 200 includes a mounting plate 210. A height adjustment plate 220 for fixing the blowing and suction mechanism 100 is connected to the mounting plate 210. A vertical adjustment mechanism 230 is provided on the mounting plate 210 to adjust the vertical movement of the height adjustment plate 220.

[0085] Therefore, the surface cleaning mechanism for display panels in this application utilizes a blowing and adsorption mechanism 100 and a height adjustment structure 200 in cooperation to clean the surface of the display panel. The blowing and adsorption mechanism 100 includes a blowing and suction hood 110, within which is a high-pressure air knife 120 that blows the display panel surface. The air nozzle of the air knife 120 faces the suction port 111 of the blowing and suction hood 110. Dust blown away by the air knife 120 is not only covered by the blowing and suction hood 110, but also adsorbed into a designated area by the vacuum adsorption interface 151 for collection, preventing the cleaned display panel from being contaminated by dust again. This blowing and adsorption mechanism 100 requires no downtime for cleaning, can be reused for extended periods, and prevents dust from scattering, thus improving the cleanliness level of the production workshop.

[0086] The surface cleaning mechanism for display panels disclosed in this application utilizes a height adjustment structure 200 to adjust the distance between the blowing and adsorption mechanism 100 and the display panel. By adjusting the distance between the blowing and adsorption mechanism 100 and the display panel, cleaning operations can be performed on display panels of different thicknesses. The height adjustment structure 200 is equipped with a height adjustment plate 220 connected to the blowing and adsorption mechanism 100. A vertical adjustment mechanism 230 is provided on the mounting plate 210 to adjust the vertical movement of the height adjustment plate 220. The vertical adjustment mechanism 230 can be adjusted automatically or manually. When the vertical adjustment mechanism 230 moves the blowing and adsorption mechanism 100 closer to the display panel, it can enhance the blowing force of the blowing and adsorption mechanism 100 and improve cleaning efficiency.
