Description

Technical Field

[0001] This utility model relates to the field of glass etching and cleaning technology, specifically a flip-top spray structure for use in highly corrosive environments. Background Technology

[0002] In the fields of electronics, information technology, and optical instruments, chemical etching is one of the core processes in the manufacture of precision glass components. In this process, glass reacts with highly corrosive etching solutions such as hydrofluoric acid and nitric acid to form predetermined patterns or thicknesses. After etching, etching solution, reaction byproducts, and impurity particles remain on the glass surface. If these are not thoroughly removed, they will not only reduce the surface smoothness and light transmittance but also trigger "secondary corrosion" in subsequent processes, severely affecting the mechanical strength and performance of the glass components. Therefore, the post-etching cleaning process plays a decisive role in the final product quality.

[0003] Currently, the industry mainly employs two technical solutions for cleaning etched glass, but both have significant drawbacks in highly corrosive environments: To remove residual corrosive substances from the glass surface, existing processes primarily use "immersion cleaning," which involves immersing the etched glass in a tank containing cleaning solution (or diluted neutralizing solution), relying on liquid convection to dissolve and remove residual substances. However, this technology has the following unavoidable problems: during repeated use, the cleaning solution continuously accumulates etching residues and reaction products, leading to continuous deterioration of water quality. Subsequent cleaned glass is prone to "secondary contamination," and the cleaning pass rate decreases significantly with each use (typically, all cleaning solutions need to be replaced after 20-30 batches). To ensure sufficient dissolution of residual substances, the immersion time needs to be controlled at 15-30 minutes, much longer than other cleaning methods. Furthermore, for complex structures such as depressions and textures on the glass surface, insufficient liquid convection during immersion can easily create "cleaning blind spots," resulting in localized residue. Utility Model Content

[0004] The purpose of this invention is to provide a flip-top spray structure for use in highly corrosive environments, in order to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a flip-top spray structure for use in highly corrosive environments, comprising a box and a cover plate. An inner platform is provided at the center of the base at the bottom of the box. A rotary motor is provided at the bottom of the inner platform, and the output end of the rotary motor extends into the interior of the box and is connected to a support plate. A supporting inner frame is provided inside the box. A U-shaped frame with a plug slot is provided inside the supporting inner frame, and a docking seat is provided at the bottom of the U-shaped frame. One end of the docking seat extends to the outside of the supporting inner frame and corresponds to the supporting plate. A fixed platform is provided at the opening of the box. A servo motor is installed on one side of the fixed platform, and the output end of the servo motor is connected to a rotating shaft. A cover plate is connected to one side of the rotating shaft through evenly arranged bait plates. Spray heads are evenly arranged on the inner side of the cover plate through a distribution pipe. An inlet pipe connected to an external high-pressure pump is provided near the bottom of the fixed platform close to the cover plate, and the output end of the inlet pipe is connected to the input end of the distribution pipe through a flexible hose.

[0006] Preferably, a liquid-retaining ring is provided on the outer side of the opening of the fixed platform, and the inner area of ​​the liquid-retaining ring matches the area of ​​the cover plate.

[0007] Preferably, the side walls of the inner support frame are provided with mesh panels, and the connection between the inner support frame and the docking seat is provided with a bearing, and the bottom of the docking seat is provided with a cross groove.

[0008] Preferably, the top of the support plate is provided with a cross-shaped locking block that corresponds to the cross-shaped locking slot.

[0009] Preferably, the base outside the inner platform is provided with an annular groove, and the outer side of the base is provided with a waste liquid pipe communicating with the annular groove.

[0010] Preferably, the inner side of the fixed platform is provided with an inner boss, and brackets are provided on both sides of the inner boss. Furthermore, the top of both sides of the inner support frame is provided with a support frame that matches the bracket.

[0011] Preferably, the inner wall of the housing and the outer surface of the supporting inner frame are both coated with a Teflon anti-corrosion coating with a thickness of 0.2-0.5mm.

[0012] This utility model relates to a flip-top spray structure for use in highly corrosive environments, which has significant advantages over existing technologies, as detailed below: 1. A servo motor drives the rotating shaft to open and close the top cover, ensuring even coverage of the glass surface by the spray nozzles. This not only guarantees uniform spraying but also avoids the dead zones caused by the fixed position of traditional spray nozzles. The spray nozzles, evenly distributed through distribution pipes on the inner side of the cover, combined with the pressure provided by the high-pressure pump, efficiently remove dirt from the glass surface, improving cleaning efficiency. A liquid-retaining ring on the outer side of the fixed platform opening, with an inner area matching the cover area, effectively prevents acid splashing during spraying, ensuring operator safety.

[0013] 2. The internal support frame and U-shaped frame of the chamber are driven by a rotary motor, which allows the glass to rotate slowly during the high-pressure spraying process. This not only ensures the uniformity of the spraying, but also avoids the problem of glass breakage caused by uneven local stress.

[0014] In summary, the flip-top spray structure of this invention, used in highly corrosive environments, not only significantly improves spraying efficiency and uniformity, enhances structural stability and durability, and optimizes corrosion resistance, but also improves operational safety and convenience, saves resources, and reduces environmental pollution.

[0040] A fixed platform 4 is provided at the opening of the housing 3. A servo motor 11 is installed on one side of the fixed platform 4, and the output end of the servo motor 11 is connected to a rotating shaft 14. A cover plate 9 is connected to one side of the rotating shaft 14 through a uniformly arranged bait plate 13. Spray heads 8 are evenly arranged on the inner side of the cover plate 9 through a distribution pipe 10. An inlet pipe 15 connected to an external high-pressure pump is provided near the bottom of the fixed platform 4 near the cover plate 9, and the output end of the inlet pipe 15 is connected to the input end of the distribution pipe 10 through a hose 12.

[0041] A liquid-retaining ring 5 is provided on the outer side of the opening of the fixed platform 4, and the inner area of ​​the liquid-retaining ring 5 matches the area of ​​the cover plate 9.

[0042] A servo motor 11 is mounted on one side of the fixed platform 4. The servo motor 11 is mounted on the fixed platform 4 via a fixed bracket, and its output end is connected to a rotating shaft 14. The servo motor 11 is a high-precision, high-torque model to ensure that the rotating shaft 14 can rotate smoothly and accurately.

[0043] A cover plate 9 is connected to one side of the rotating shaft 14 via evenly spaced bait plates 13. The bait plates 13 are made of high-strength material to ensure they can withstand the weight of the cover plate 9 and the impact of the spray liquid when the rotating shaft 14 rotates. Spray heads 8 are evenly arranged on the inner side of the cover plate 9 via distribution pipes 10. The number and distribution of the spray heads 8 are optimized to ensure that the spray liquid can evenly cover the entire interior of the tank.

[0044] The bottom of the fixed platform 4 near the cover plate 9 is equipped with an inlet pipe 15 that connects to an external high-pressure pump. The inlet pipe 15 is made of high-pressure resistant material, and its output end is connected to the input end of the distribution pipe 10 via a hose 12. The hose 12 has good flexibility, which can adapt to the rotation of the rotating shaft 14, while ensuring smooth liquid transmission.

[0045] A liquid-retaining ring 5 is installed on the outer side of the opening of the fixed platform 4. The inner area of ​​the liquid-retaining ring 5 matches the area of ​​the cover plate 9 to ensure that liquid will not overflow from the opening of the tank 3 during spraying. The liquid-retaining ring 5 is made of corrosion-resistant material and can be used for a long time without deformation.

[0046] In this embodiment of the application, the servo motor 11 on one side of the fixed platform 4 is first started. The servo motor 11 drives the rotating shaft 14 to rotate clockwise. The rotating shaft 14 drives the cover plate 9 to flip upward through the evenly arranged bait plates 13 until the opening of the box 3 is fully exposed. Then, the etched glass to be cleaned is inserted into the insertion slot 22 of the U-shaped frame 23 inside the inner support frame 21, ensuring that the glass is stably locked in the insertion slot 22. Next, the inner support frame 21 with the glass assembled is moved to the opening of the box 3, so that the support frame 24 on both sides of the top of the inner support frame 21 is aligned with the bracket 6 on the inner boss 7 on the inner side of the fixed platform 4 and placed. At the same time, it is ensured that the cross slot 28 of the bottom docking seat 26 of the inner support frame 21 is precisely engaged with the cross block 27 of the top support plate 17 of the inner platform 19, completing the transmission docking between the inner support frame 21 and the support plate 17.

[0047] Restart the servo motor 11 and control the rotating shaft 14 to rotate counterclockwise, causing the cover plate 9 to flip downwards until the cover plate 9 completely covers the opening of the box 3. At this time, the liquid-blocking ring 5 on the outside of the opening of the fixed platform 4 is tightly fitted with the edge of the cover plate 9 to form a sealing structure to prevent liquid splashing during subsequent spraying. Then connect the output end of the external high-pressure pump to the liquid inlet pipe 15 near the bottom of the cover plate 9 on the fixed platform 4. Check whether the hose 12 between the liquid inlet pipe 15 and the distribution pipe 10 is firmly connected, and ensure that the hose 12 is not bent or damaged to ensure that the cleaning fluid transmission channel is unobstructed.

[0048] The external high-pressure pump is started to pressurize the highly corrosive cleaning solution (or neutralizing solution) and deliver it to the inlet pipe 15. The cleaning solution flows into the hose 12 through the inlet pipe 15, and then into the distribution pipe 10 inside the cover plate 9 through the hose 12. Finally, it is sprayed into the box 3 through the spray nozzles 8 evenly arranged on the distribution pipe 10. At the same time, the rotary motor 18 at the bottom of the inner platform 19 is started. The output end of the rotary motor 18 drives the support plate 17 to rotate at a constant speed. The support plate 17 drives the docking seat 26, U-shaped frame 23 and glass to rotate synchronously through the engagement of the cross block 27 and the cross slot 28. During this process, the mesh plate surface 16 on the side wall of the inner support frame 21 can make the spray liquid flow smoothly and avoid the liquid from accumulating inside the inner support frame 21, so as to achieve 360° spray cleaning of the glass surface without dead angles. In addition, the bearing 25 at the connection between the inner support frame 21 and the docking seat 26 can reduce the friction of the docking seat 26 when it rotates and ensure the smooth rotation process.

[0049] The waste liquid (including cleaning fluid and etching residue) generated during the spray cleaning process flows downward along the inner wall of the tank 3 (the inner wall is coated with a 0.2-0.5mm Teflon anti-corrosion coating to reduce waste liquid corrosion). Since the height of the inner platform 19 is slightly higher than the annular groove 20 inside the base 2, the waste liquid will naturally collect in the annular groove 20 and finally be discharged to the designated corrosive waste liquid treatment equipment through the waste liquid pipe 1 connected to the annular groove 20 on the outside of the base 2, thus avoiding the waste liquid remaining in the base 2 and causing equipment corrosion.

[0050] After the cleaning operation is completed, first turn off the external high-pressure pump to stop the liquid supply from the spray head 8, then turn off the rotary motor 18 to stop the support plate 17 and the glass from rotating; then start the servo motor 11 to drive the rotating shaft 14 to make the cover plate 9 flip upward again and open the opening of the box 3; finally, lift the inner support frame 21 upward to separate the support frame 24 from the bracket 6 and the cross slot 28 from the cross block 27, take the inner support frame 21 out of the box 3, and pull out the cleaned glass from the insertion slot 22 of the U-shaped frame 23 to complete a single cleaning operation.
