[0001] This invention relates to the field of CVD product cleaning technology, and in particular to an automatic high-pressure cleaning device. Background Technology

[0002] Chemical vapor deposition (CVD) is one of the core processes in the manufacturing of OLED displays. During the manufacturing process, the electrodes of the product require high-pressure cleaning to prevent the formation of stubborn deposits.

[0003] In related technologies, product cleaning relies on manual labor, requiring operators to hold high-pressure spray guns for cleaning. This is extremely difficult to perform, and the powerful reaction force generated by the high-pressure water jet can easily lead to operator fatigue, resulting in low cleaning efficiency, inconsistent results, and difficulty in thoroughly removing deposits from the product surface and hidden areas, thus affecting product quality. Furthermore, manual operation carries a significant risk of bumping and scratching the product, and the cleaning solution can easily splash into adjacent tanks, causing cross-contamination.

[0004] Therefore, there is an urgent need to design an automatic high-pressure cleaning device to solve the above technical problems. Summary of the Invention

[0017] As an optional technical solution for an automatic high-pressure cleaning device, the nozzle unit includes a second connecting plate, a cleaning nozzle, and a purging nozzle.

[0025] In this automatic high-pressure cleaning equipment, during product cleaning, the drive assembly moves the robotic arm outside the housing, aligning the nozzle unit with the cleaning area of ​​the product within the receiving cavity. The high-pressure cleaning program is then initiated, with the nozzle unit spraying high-pressure water jets to remove and clean the deposits on the product. Compared to traditional manual handheld spray gun cleaning, this invention achieves precise spray positioning through automated control of the robotic arm by the drive assembly. This solves the problems of uneven cleaning effects and cross-contamination of cleaning solutions caused by unstable spray distance and angle during manual cleaning, significantly improving cleaning efficiency and consistency. Simultaneously, it avoids operator fatigue caused by the reaction force of holding the spray gun, increasing production efficiency, reducing safety risks associated with manual operation, and minimizing the risk of operators bumping or scratching products, thus improving product quality.

Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.

[0045] The technical solution of the present invention will be further described below with reference to the accompanying drawings and specific embodiments.

[0046] This embodiment provides an automatic high-pressure cleaning device that requires no manual operation, improves cleaning efficiency and product quality, and reduces the risk of product damage and cross-contamination of cleaning solutions between adjacent tanks.

[0047] like Figures 1-6 As shown, the automatic high-pressure cleaning equipment mainly includes a housing 10, a drive assembly 20, and a cleaning assembly 30. The housing 10 has a receiving chamber for holding the product 100. The drive assembly 20 is mounted on the outer wall of the housing 10. The cleaning assembly 30 includes a robotic arm 31 and a nozzle unit 32. One end of the robotic arm 31 is connected to the drive assembly 20, and the other end is connected to the nozzle unit 32. The drive assembly 20 can move the robotic arm 31 so that the nozzle unit 32 faces the product 100.

[0048] Based on the above design, when cleaning product 100, the automatic high-pressure cleaning equipment uses the drive component 20 to move the robotic arm 31 outside the housing 10, aligning the nozzle unit 32 with the cleaning area of ​​product 100 within the accommodating cavity. This initiates the high-pressure cleaning program, where the nozzle unit 32 sprays high-pressure water jets to remove and clean the deposits on product 100. Compared to traditional manual handheld spray gun cleaning, this embodiment achieves precise spray positioning through the automated control of the robotic arm 31 by the drive component 20. This solves the problems of uneven cleaning effects and cross-contamination of cleaning solutions caused by unstable spray distance and angle during manual cleaning, significantly improving cleaning efficiency and consistency. Simultaneously, it avoids operator fatigue caused by the reaction force of the handheld spray gun, improving production efficiency, reducing safety risks associated with manual operation, and lowering the risk of operators bumping or scratching product 100, thus improving product 100 quality.

[0049] Optionally, the product 100 in this embodiment can be configured as an OLED display screen.

[0050] like Figure 1 , Figure 2 and Figure 5As shown, the drive assembly 20 in this embodiment includes a slide rail 21, a first connecting plate 22, and a first drive member 23. The slide rail 21 is disposed on the outer wall of the housing 10. The first connecting plate 22 is slidably connected to the slide rail 21. The end of the robotic arm 31 away from the nozzle unit 32 is fixedly connected to the first connecting plate 22. The first drive member 23 is drivenly connected to the first connecting plate 22 to drive the first connecting plate 22 to slide along the slide rail 21.

[0051] Specifically, the first driving component 23 uses a servo motor and a reducer to transmit power to the first connecting plate 22 through a gear and rack transmission mechanism. The first connecting plate 22 is in sliding engagement with the slide rail 21 fixed to the outer wall of the housing 10. The first driving component 23 can drive the first connecting plate 22 to slide linearly back and forth along the slide rail 21. The end of the robotic arm 31 away from the nozzle unit 32 is securely connected to the first connecting plate 22 by bolting or welding.

[0052] like Figures 3-6 As shown, the cleaning assembly 30 in this embodiment also includes a movable arm 33. One end of the movable arm 33 is movably connected to the end of the robotic arm 31 away from the slide rail 21, and the other end of the movable arm 33 is provided with a nozzle unit 32. The movable arm 33 has an extended posture and a retracted posture. When the movable arm 33 is in the extended posture, the nozzle unit 32 faces the product 100; when the movable arm 33 is in the retracted posture, the nozzle unit 32 is offset from the product 100.

[0053] It should be noted that, Figure 3 The movable arm 33 at the upper left corner of the middle shell 10 is in an unfolded position, and the movable arm 33 at the upper right corner is in a retracted position.

[0054] When the automatic high-pressure cleaning equipment is in the cleaning operation state, the movable arm 33 switches to the extended position, and the nozzle unit 32 faces the part of the product 100 to be cleaned; when the product 100 needs to be inspected manually, the movable arm 33 switches to the retracted position, and the nozzle unit 32 is staggered with the product 100 to avoid contact with the product 100.

[0055] like Figures 5-6 As shown, in order to realize the posture switching of the movable arm 33, the cleaning assembly 30 is also provided with a second driving member 34. One end of the second driving member 34 is fixed on the robotic arm 31, and the other end is connected to the movable arm 33 to drive the movable arm 33 to switch between the unfolded posture and the retracted posture.

[0056] Specifically, in this embodiment, the second driving component 34 includes a telescopic rod 341, a rotating arm 342, and a connecting shaft 343. The fixed end of the telescopic rod 341 is fixedly connected to the robotic arm 31, and the telescopic end of the telescopic rod 341 is hinged to one end of the rotating arm 342. One end of the connecting shaft 343 is fixedly connected to the other end of the rotating arm 342, and the other end of the connecting shaft 343 is connected to the movable arm 33. The connecting shaft 343 is partially disposed within the robotic arm 31. The telescopic end of the telescopic rod 341 can drive the rotating arm 342 to rotate, so that the rotating arm 342 drives the movable arm 33 to switch between an extended posture and a retracted posture via the connecting shaft 343. Exemplarily, the telescopic rod 341 can be a cylinder, a hydraulic cylinder, or an electric telescopic rod, and the rotating arm 342 can adopt a gear or linkage structure.

[0057] During operation, the telescopic end of the telescopic rod 341 extends and retracts, driving the rotating arm 342 to rotate around the axis of the connecting shaft 343. The rotating arm 342 then drives the movable arm 33 to rotate synchronously through the connecting shaft 343, realizing the switching between the extended and retracted postures of the movable arm 33.

[0058] The structure of the second drive component 34 transforms the linear motion of the telescopic rod 341 into the circular motion of the rotating arm 342, thereby driving the movable arm 33 to rotate. The power transmission path is clear and efficient, ensuring the accuracy and stability of the movable arm 33's posture switching. The connecting shaft 343 is installed inside the robotic arm 31 via bearings, which not only ensures rotational flexibility but also provides effective support for the connecting shaft 343, improving the stability of the second drive component 34.

[0059] like Figures 3-4 As shown, the nozzle unit 32 in this embodiment includes a second connecting plate 321, a cleaning nozzle 322, and a purging nozzle 323. The second connecting plate 321 is mounted on the movable arm 33. The cleaning nozzle 322 and the purging nozzle 323 are both disposed on the second connecting plate 321, and the spraying directions of the cleaning nozzle 322 and the purging nozzle 323 are both directed toward the part of the product 100 to be cleaned.

[0060] The cleaning nozzle 322 and the purging nozzle 323 are integrated on the second connecting plate 321, enabling the automatic high-pressure cleaning equipment to complete high-pressure cleaning and drying in one station. The cleaning process can be completed without transferring the product 100, significantly shortening the work cycle and improving production efficiency. The high-pressure jet from the cleaning nozzle 322 effectively removes stubborn deposits, while the purging nozzle 323 promptly dries any residual cleaning fluid on the surface of the product 100, preventing particle explosions or secondary deposit adhesion caused by residual cleaning fluid, thus significantly improving the cleaning quality of the product 100. The integrated design also reduces the installation space of the nozzle unit 32, making the automatic high-pressure cleaning equipment more compact.

[0061] The automatic high-pressure cleaning equipment in this embodiment also includes a cleaning fluid storage tank and a compressed air source. The cleaning nozzle 322 is connected to the cleaning fluid storage tank through a high-pressure pipeline. A high-pressure pump and a flow control valve can be installed on the high-pressure pipeline to adjust the pressure and flow rate of the cleaning fluid. The purging nozzle 323 is connected to the compressed air source through an air pipe. A pressure regulating valve and a solenoid valve can be installed on the air pipe to control the pressure and timing of the compressed air injection.

[0062] The cleaning fluid storage tank provides a stable supply of cleaning fluid to the cleaning nozzle 322, avoiding operational interruptions caused by manual addition of cleaning fluid and improving operational continuity. The compressed air source provides a continuous and stable supply of high-pressure air to the purging nozzle 323, ensuring effective drying. The control valves on the high-pressure pipeline allow for precise adjustment of cleaning pressure, flow rate, and purging pressure, adapting to the cleaning needs of different products 100. This ensures thorough removal of stubborn deposits while preventing damage to the product 100 due to excessive pressure. The automatically controlled valves respond quickly, enabling precise switching between cleaning and purging processes, further improving operational efficiency and cleaning effectiveness.

[0063] like Figure 4 As shown, in this embodiment, the second connecting plate 321 is L-shaped and includes an integrally formed first connecting portion 324 and a second connecting portion 325. The first connecting portion 324 is connected to the movable arm 33, and both the cleaning nozzle 322 and the blowing nozzle 323 are connected to the second connecting portion 325. Multiple blowing nozzles 323 are provided, and the multiple blowing nozzles 323 are equally spaced along the width direction and / or length direction of the product 100; multiple cleaning nozzles 322 are provided, and the multiple cleaning nozzles 322 are equally spaced along the width direction and / or length direction of the product 100.

[0064] The L-shaped second connecting plate 321 can adapt to the spatial structure of the accommodating chamber, allowing the nozzle unit 32 to be closer to the part of the product 100 to be cleaned, while avoiding interference with other components. The evenly spaced distribution of multiple cleaning nozzles 322 and multiple blowing nozzles 323 ensures that the surface of the product 100 is fully covered, eliminating cleaning dead zones and improving the uniformity of cleaning and drying. The spacing of the cleaning nozzles 322 ensures that the high-pressure water jet acts evenly on the surface of the product 100, avoiding damage to the product 100 due to excessive local pressure, while also reducing water consumption and saving cleaning costs.

[0065] In some alternative embodiments, the purge nozzle 323 is designed with a conical angle, which enhances the superposition effect of airflow, thereby increasing the drying intensity, shortening the drying time, and further improving production efficiency.

[0066] For example, the second connecting plate 321 is integrally stamped from stainless steel, providing high structural strength and corrosion resistance. The purge nozzle 323 consists of six omnidirectional air nozzles, evenly distributed in two rows and three columns, with a conical spray direction to achieve superimposed airflow. The cleaning nozzles 322 are evenly distributed in single or double rows, with partial overlap in the spray range of adjacent cleaning nozzles 322 to avoid cleaning dead zones. The nozzles are connected to the second connecting plate 321 via a threaded connection for easy disassembly and replacement.

[0067] like Figure 1 and Figure 3 As shown, multiple cleaning components 30 are provided, and the multiple cleaning components 30 are distributed on opposite sides of the product 100 to clean the front and back of the product 100.

[0068] For example, four cleaning components 30 can be provided, corresponding to the four sides of the product 100 respectively, or two symmetrical cleaning components 30 can be provided on the front and back. The drive components 20 of each cleaning component 30 can be synchronously controlled by the same controller to ensure that the movement trajectory and operation rhythm of each nozzle unit 32 are consistent.

[0069] In this embodiment, the nozzle unit 32 is located in the accommodating cavity, and a preset distance is provided between the nozzle unit 32 and the top of the housing 10 to prevent the cleaning liquid sprayed by the nozzle unit 32 from splashing out of the housing 10.

[0070] During the cleaning operation, after the high-pressure water jet impacts the surface of the product 100, the water flow falls vertically back under the action of gravity. Some of the splashed water droplets fly upward due to their initial kinetic energy, but their kinetic energy is exhausted when they reach a preset distance and they cannot jump out of the top opening of the housing 10. This effectively blocks the splashing of cleaning fluid during the cleaning process, preventing the cleaning fluid from splashing out of the housing 10 and causing pollution to the surrounding environment. It also prevents cross-contamination caused by the splashing of the cleaning fluid into other tanks, ensuring the cleanliness of the production environment and the normal operation of other equipment.

[0071] For example, the preset distance can be set to 100cm-200cm.
