[0030] The present invention will be further described below with reference to the accompanying drawings and specific embodiments, so that those skilled in the art can better understand and implement the present invention. However, the embodiments are not intended to limit the present invention.

[0031] Referring to Figures 1 and 2, in one embodiment of this utility model, a screen cleaning device is disclosed, comprising:

[0032] Support 1, which is provided with a conveying channel 11, through which a conveying line passes;

[0033] A cleaning assembly is disposed on the support 1 and located directly above the conveyor line. The cleaning assembly includes a lifting mechanism 2, an ion bar 23, and a dry ultrasonic dust collector (USC) and an electrostatic brush 21 disposed on the lifting mechanism 2. The electrostatic brush 21, the USC, and the ion bar 23 are arranged sequentially along the conveying direction of the conveyor line.

[0034] The screen cleaning device described in this embodiment uses a conveyor line to transport the screen through the conveyor channel 11 of the support 1. During the transport process, the screen is cleaned one by one by the cleaning components above, simplifying the screen cleaning process and improving the screen cleaning efficiency. When the screen passes under the electrostatic brush 21, it is swept and adsorbed by the electrostatic brush 21. At the same time, the electrostatic brush 21 uses insulating material to balance the charge distribution. When the screen passes under the USC, the ultrasonic high-frequency vibration of the USC combines with the gas turbulence, causing the particles on the screen surface to detach, achieving non-contact physical cleaning. Finally, when the screen passes under the ion bar 23, the ion bar 23 generates a large number of positive and negative charges through a high-voltage generator and blows the airflow containing positive and negative charges toward the screen to neutralize its static electricity, thus achieving the purpose of removing static electricity from the screen. The screen includes an OLED screen.

[0035] Referring to FIG1, in one embodiment of the present invention, the USC includes a gas turbulence generator 26 and an ultrasonic generator 22. The ultrasonic generator 22 is disposed above the conveyor line. The ultrasonic generator 22 and the gas turbulence generator 26 are connected by an air pipe 25. The ultrasonic generator 22 generates high-frequency vibration through ultrasonic waves, and the gas turbulence generator 26 generates turbulence through high-pressure airflow.

[0036] In one embodiment of this utility model, the electrostatic brush 21 is made of nylon material, which has the characteristics of not scratching the screen, not shedding lint, and not generating dust. The resistance value of the nylon material is 10 ohms. 6 ~10 8 Ohms have insulating properties and can maintain the distribution of charge.

[0037] Referring to FIG2, in one embodiment of the present invention, the ion fan rod 23 is disposed on the support 1. In other embodiments, the ion fan rod 23 may be disposed on the lifting mechanism 2 so as to flexibly adjust its height to meet the needs of different scenarios.

[0038] Referring to Figures 1 and 2, in one embodiment of this utility model, the electrostatic brush 21, the USC, and the ion bar 23 all extend laterally along the conveyor line to ensure that the horizontal edge of the screen is cleaned without dead corners, and can also meet the cleaning needs of wide screens. The horizontal direction refers to the direction along the width of the conveyor line.

[0039] Referring to FIG2, in one embodiment of the present invention, the ion fan rod 23 is rotatably mounted on the support 1, and the rotation axis 231 of the ion fan rod 23 extends along the lateral direction. The airflow spray angle of the ion fan rod 23 can be adjusted by flipping it up and down to enhance the uniformity of positive and negative charge coverage.

[0040] Referring to FIG2, in one embodiment of the present invention, the support 1 includes a first support column 12, a second support column 13, a crossbeam, and a mounting plate 16. The first support column 12 and the second support column 13 are disposed on opposite sides of the conveyor line. The crossbeam is disposed above the conveyor line, and the two ends of the crossbeam are respectively connected to the first support column 12 and the second support column 13. The mounting plate 16 is vertically connected to the crossbeam. The cleaning component is disposed on the mounting plate 16 to ensure the long-term stability of the device and prevent the vibration of the support 1 from interfering with the cleaning process.

[0041] Referring to FIG2, in one embodiment of the present invention, the first support column 12, the second support column 13, and the crossbeam are all made of profiles. The hollow structure inside the profiles reduces the overall weight, while the reinforcing rib design improves the compressive strength of the support 1.

[0042] Referring to FIG1, in one embodiment of the present invention, the lifting mechanism 2 includes a linear motor, which drives the USC and the electrostatic brush 21 to lift synchronously, ensuring the repeatability of the lifting positions of the USC and the electrostatic brush 21 and avoiding overshoot or lag caused by inertia.

[0043] Referring to FIG1, in one embodiment of the present invention, the lifting mechanism 2 further includes two slide rails 27 disposed on the mounting plate 16. The two slide rails 27 extend vertically and are distributed on both sides of the linear motor. The USC and the electrostatic brush 21 are slidably connected to the two slide rails 27. The two slide rails 27 form a symmetrical guide structure to counteract the off-center load torque of the USC and the electrostatic brush 21 during the lifting process, thereby reducing the shaking of the cleaning components.

[0044] Referring to Figures 3 and 4, in one embodiment of this utility model, the height of the electrostatic brush 21 is lower than that of the ultrasonic generator. When the lifting mechanism 2 lowers the electrostatic brush 21 and the ultrasonic generator 22, the electrostatic brush 21 contacts the screen surface first, ensuring that the bristles of the electrostatic brush 21 bend significantly after contacting the screen, thereby increasing the contact area between the electrostatic brush 21 and the screen.

[0045] Referring to FIG2, in one embodiment of the present invention, the crossbeam includes a first crossbeam 14 and a second crossbeam 15 arranged vertically opposite each other. The upper and lower ends of the mounting plate 16 are respectively connected to the first crossbeam 14 and the second crossbeam 15, which can further improve the structural strength of the support 1.

[0046] Referring to FIG1, in one embodiment of the present invention, the conveying channel 11 is the space between the first support column 12 and the second support column 13, and the conveying channel 11 is disposed below the crossbeam, making full use of the space between the first support column 12 and the second support column 13.

[0047] Referring to FIG1, the lifting mechanism 2 includes a connecting plate 24. One side of the connecting plate 24 is slidably connected to the slide rail 27 and connected to the output end of the linear motor. The other side of the connecting plate 24 is connected to the ultrasonic generator and the electrostatic brush 21. The connecting plate 24 integrates the slide rail 27, the ultrasonic generator 22 and the electrostatic brush 21, simplifying the structure of the cleaning device.

[0048] Referring to FIG1, in one embodiment of the present invention, the ultrasonic generator is fixedly connected to both ends of the transverse direction by a first fixing member 3, and the first fixing member 3 is fixedly connected to the connecting plate 24.

[0049] Referring to Figure 1, in one embodiment of this utility model, the electrostatic brush 21 is provided with a second fixing member 4 at both ends along the transverse direction. The second fixing member 4 is provided with a strip hole 41 extending in the vertical direction. The screw passes through the strip hole 41 and is threaded to the first fixing member 3, thereby realizing the fixed connection between the first fixing member 3 and the second fixing member 4. The strip hole 41 is conducive to fine-tuning the height of the second fixing member 4, and thus fine-tuning the height of the electrostatic brush 21.

[0050] Referring to Figures 3 and 4, in one embodiment of this utility model, the ultrasonic generator 22 of the USC and the electrostatic brush 21 are disposed on the same side of the mounting plate 16, and the ion bar 23 is disposed on the other side of the mounting plate 16 relative to the electrostatic brush 21. The purpose is to isolate the airflow direction of the ultrasonic generator 22 from the airflow direction of the ion bar 23, so as to avoid cross-interference of airflow.

[0051] The working principle of the screen cleaning device described in this utility model is as follows:

[0052] The lifting mechanism adjusts the height of the electrostatic brush 21 and the ultrasonic generator 22 so that the electrostatic brush 21 can contact the screen on the conveyor line. Then, the power supply of the ion air bar 23 and the USC is turned on. As the conveyor line transports the screen through the conveyor channel 11, the electrostatic brush 21 sweeps across the screen surface to remove large dust particles. Then, the high-frequency vibration and eddy current of the USC remove the fine dust. Finally, the ion air bar 23 blows an airflow containing a large number of positive and negative charges toward the screen to neutralize the static electricity of the screen. After the screen is cleaned, it is conveyed to the next station.

[0053] Obviously, the above embodiments are merely illustrative examples for clear explanation and are not intended to limit the implementation. Those skilled in the art will recognize that other variations or modifications can be made based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. However, obvious variations or modifications derived therefrom are still within the protection scope of this invention.
