Description

Technical Field

[0001] This utility model relates to the field of glass processing and cleaning technology, and in particular to a spray cleaning device for glass etching. Background Technology

[0002] In the field of glass processing technology, after etching processes, special glasses such as TGV (Through-Vein Glass) and ultra-thin glass require thorough cleaning of residual etching solution, glass debris, and other contaminants to ensure the quality of subsequent processes such as coating and photolithography. Traditional glass etching post-etching cleaning devices often employ single-sided or fixed-position spray structures, which have the following shortcomings:

[0003] On the one hand, spraying in a single direction is difficult to cover the entire surface of the glass, especially the inside of the through-holes of TGV glass, the edge areas, and the sides of ultra-thin glass, where contaminants are easily left behind, resulting in insufficient cleaning. On the other hand, fixed-position spray heads cannot adjust the spray range according to the size or structure of the glass, resulting in poor cleaning uniformity. For ultra-thin glass, excessive local pressure may even cause it to break. In addition, the liquid supply system of traditional cleaning devices lacks an effective filtration and pressure regulation mechanism. Particulate impurities mixed in the cleaning liquid can easily clog the nozzles, and pressure fluctuations will affect the spray force, further reducing cleaning efficiency.

[0004] The aforementioned problems not only affect the cleanliness of the glass, but also lead to a decrease in the yield of subsequent processes and an increase in production costs. Therefore, there is an urgent need for a glass etching post-etching spray cleaning device that can achieve all-round coverage, uniform spraying, and stable liquid supply to meet the high-precision cleaning needs of special glasses such as TGV glass and ultra-thin glass.

[0033] To make the objectives, technical solutions, and advantages of this application clearer, the technical solutions of this application will be clearly and completely described below in conjunction with specific embodiments and corresponding drawings.

[0034] Example

[0035] like Figures 1 to 4 As shown, the glass etching post-spray cleaning device of this utility model includes a cleaning tank 1, a spray module, a drive module, and a liquid supply module 6. The spray module includes a side spray mechanism 2 and a top spray mechanism 3. The drive module includes a pneumatic transmission assembly 4 and a guide rail assembly 5. The liquid supply module 6 includes a liquid storage tank 60, a main conveying pipe 61, a spray water pump 62, a filter device 63, a side spray conveying pipe 64, a top spray conveying pipe 65, and a pressure relief device 66. The specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings.

[0036] The cleaning tank 1 is the core component of the overall structure. It is used to hold the glass to be cleaned and provide a cleaning environment. The cleaning tank 1 is placed on the support 7 to ensure the overall stability of the device. The cleaning tank 1 is equipped with a spray module. The side spray mechanism 2 in the spray module is arranged on the inner wall of the cleaning tank 1. The top spray mechanism 3 is connected to the top of the cleaning tank 1 through the guide rail assembly 5 and can move under the guidance of the guide rail assembly 5.

[0037] The side spraying mechanism 2 includes multiple side spray pipes 20, side spray nozzles 21 connected to them, and fixing components. The side spray pipes 20 are arranged horizontally along the inner wall of the cleaning tank 1 and are fixedly connected to the side wall of the cleaning tank 1 by a suitable fixing method. One end of the side spray pipe 20 is connected to the side spraying conveying pipe 64, and the other end is closed. The side spray nozzles 21 are evenly distributed on the side spray pipes 20, and their spray direction is towards the central area of ​​the cleaning tank 1, which can effectively clean the sides and edge areas of the glass. CFD fluid simulation verification shows that the side nozzles generate eddies with a depth of ≥5mm at a pressure of 0.25MPa, which can clean through holes with a diameter of ≥0.3mm.

[0038] The top spraying mechanism 3 includes a top spray pipe 30, top spray nozzles 31 connected to it, a telescopic hose 32, and a guide rail assembly 5. The top spray pipe 30 is connected to the top of the cleaning tank 1 via the guide rail assembly 5. One end of the top spray pipe 30 is connected to the top spray delivery pipe 65 via the telescopic hose 32, while the other end is closed. The top spray nozzles 31 are evenly distributed on the top spray pipe 30, and their spray direction is vertically downward, used to clean the upper surface of the glass. The guide rail assembly 5 includes a guide rail 50 and a guide slider 51. The guide rail 50 is set on the cleaning tank 1, and the guide slider 51 is connected to the other end of the top spray pipe 30, allowing it to slide on the guide rail 50. The pneumatic transmission assembly 4 is a rodless cylinder, with its transmission end connected to one end of the top spray pipe 30. When the rodless cylinder operates, it drives the top spray pipe 30 to reciprocate along the guide rail 50, thereby expanding the cleaning range and improving cleaning uniformity. Limit switches (not shown in the figure) are installed at both ends of the guide rail 50 to limit the movement range of the top spray pipe 30. The limit switches are connected to the rodless cylinder solenoid valve via PLC, and the movement stroke is ≤90% of the length of the cleaning tank.

[0039] The liquid supply module 6 provides cleaning fluid to the spray module. The storage tank 60 is connected to an external water inlet pipe and stores the cleaning fluid. One end of the main delivery pipe 61 is connected to the storage tank 60, and the other end is connected to the side spray delivery pipe 64 and the top spray delivery pipe 65, respectively. A spray pump 62 and a filter device 63 are installed on the main delivery pipe 61. The filter device 63 filters the cleaning fluid, removing particulate impurities and ensuring the cleanliness of the spray fluid. The side spray delivery pipe 64 and the top spray delivery pipe 65 provide cleaning fluid to the side spray mechanism 2 and the top spray mechanism 3, respectively. The pressure relief device 66 includes a connecting pipe 660 and a pressure relief valve 661 installed on the connecting pipe 660. One end of the connecting pipe 660 is connected to the inlet of the spray pump 62, and the other end is connected to the outlet of the spray pump 62. The pressure relief valve 661 regulates the pressure at the inlet and outlet of the pump to ensure the stable operation of the liquid supply module 6. In one specific embodiment, when cleaning ultra-thin glass with a thickness ≤0.5mm, the opening pressure of the pressure relief valve 661 is set to 0.4MPa±0.05MPa to prevent pressure fluctuations from causing the ultra-thin glass to break. The spray water pump output pressure is 0.2-0.3MPa. The filtration device is a 20μm precision filter.

[0040] The bottom of the cleaning tank 1 is equipped with a collection tank 8, and the bottom of the collection tank 8 is provided with a liquid outlet pipe 9. The bottom of the collection tank 8 is designed to be inclined. A filter screen (not shown in the figure) is installed in the collection tank 8 to intercept large particulate impurities generated during the cleaning process. The inclined bottom design facilitates the concentrated flow of waste liquid to the liquid outlet pipe 9, and finally discharges it from the device or returns it to the storage tank 60.

[0041] In actual operation, the glass to be cleaned is placed in the cleaning tank 1. After the device is started, the cleaning solution is transported from the storage tank 60 to the spray module via the main delivery pipe 61. The cleaning solution first passes through the filter device 63 to remove particulate impurities. Then, the spray pump 62 operates, delivering the cleaning solution to the side spray delivery pipe 64 and the top spray delivery pipe 65. After receiving the cleaning solution, the side spray pipe 20 of the side spray mechanism 2 sprays it into the central area of ​​the cleaning tank 1 through the side spray nozzles 21, cleaning the sides and edges of the glass. The top spray pipe 30 of the top spray mechanism 3 receives the cleaning solution through the telescopic hose 32, and the top spray nozzles 31 spray it vertically downwards, covering the upper surface of the glass. At the same time, the pneumatic transmission component 4 drives the top spray pipe 30 to reciprocate along the guide rail 50, expanding the cleaning range and improving the cleaning uniformity.

[0042] The waste liquid after cleaning flows into the collection tank 8, where it passes through a filter screen to intercept large particles of impurities, and then flows along the sloping bottom surface to the outlet pipe 9. If the cleaning liquid needs to be recycled, the waste liquid can be returned to the storage tank 60 through the outlet pipe 9. The storage tank 60 can be equipped with a level sensor and a temperature sensor (not shown in the figure) according to actual conditions. The level sensor and the temperature sensor are located on the side wall of the storage tank 60. The level sensor is used to detect the amount of cleaning liquid in the storage tank 60. When the level is lower than the set value, the external water inlet pipe automatically replenishes the cleaning liquid. The temperature sensor is used to monitor the temperature of the cleaning liquid. When the temperature deviates from the set range, the optimal temperature of the cleaning liquid can be maintained by a corresponding heating or cooling device (not shown in the figure). The sensors are controlled by a PLC control system, which is existing technology and will not be described in detail here.

[0043] During operation, a protective cover (not shown in the figure) can be installed on the top of the cleaning tank 1. The protective cover is connected to the top edge of the cleaning tank 1 via a hinge. An opening is provided on the side wall of the protective cover, through which the telescopic hose 32 of the top spray mechanism 3 passes. The top spray mechanism 3 is located inside the protective cover. A rotating sealing ring (made of fluororubber) is provided at the opening to dynamically seal with the telescopic hose 32. The protective cover remains closed to prevent liquid splashing during cleaning. An observation window made of transparent material can also be provided on the protective cover to facilitate real-time monitoring of the cleaning process by the operator. After cleaning, the protective cover is opened, and the cleaned glass is removed, completing the entire cleaning process.

[0044] To enable those skilled in the art to fully understand and implement this utility model, the following supplementary explanation of the specific implementation principle of this utility model is provided in conjunction with a specific application scenario.

[0045] First, carefully place the TVG glass to be cleaned into the cleaning tank 1, ensuring it is centered. After starting the device, the cleaning solution in the storage tank 60 begins to be transported to the spray module through the main delivery pipe 61. Before the cleaning solution enters the spray module, the filter device 63 intercepts particulate impurities in the cleaning solution to ensure the purity of the sprayed liquid. The spray pump 62 starts working, pumping the cleaning solution to the side spray delivery pipe 64 and the top spray delivery pipe 65. At this time, the pressure relief device 66 begins to function, and the pressure relief valve 661 automatically adjusts its opening according to the preset pressure value to maintain stable pressure at the inlet and outlet of the spray pump 62, ensuring that the cleaning solution is delivered to each spray mechanism at an appropriate pressure.

[0046] Next, the side spray mechanism 2 begins operation. The side spray pipe 20 receives cleaning fluid from the side spray delivery pipe 64 and distributes it evenly to multiple side spray nozzles 21. The side spray nozzles 21 spray cleaning fluid toward the central area of ​​the cleaning tank 1 according to the designed direction, forming a high-pressure water flow covering the sides and edges of the glass. Due to the optimized distribution density and angle of the side spray nozzles 21, residues in the complex structure of the glass surface can be effectively removed.

[0047] Simultaneously, the top spray mechanism 3 also begins operation. The top spray pipe 30 receives cleaning fluid from the top spray delivery pipe 65 via the telescopic hose 32, and the top spray nozzles 31 spray vertically downwards, covering the upper surface of the glass. The rodless cylinder begins to drive the top spray pipe 30 to reciprocate along the guide rail 50, expanding the spray range and improving cleaning uniformity. The reciprocating motion of the spray branch pipe is achieved by the piston rod of the rodless cylinder. Limit switches are installed at both ends of the guide rail 50 to precisely limit the movement range of the top spray pipe 30, ensuring that it operates within the predetermined area.

[0048] During the cleaning process, waste liquid flows down the glass surface and collects in the collection tank 8 at the bottom of the cleaning tank 1. The filter screen in the collection tank 8 has a multi-layer structure design, which can effectively capture particles of different sizes and prevent them from entering subsequent pipelines and causing blockages. The inclined design at the bottom of the collection tank 8 allows the waste liquid to flow smoothly to the outlet pipe 9 and finally back to the storage tank 60. The liquid level sensor in the storage tank 60 monitors the cleaning liquid level in real time. When the liquid level is lower than the set value, the external water inlet pipe automatically opens to replenish the cleaning liquid. The temperature sensor continuously monitors the temperature of the cleaning liquid. When the temperature deviates from the set range, the heating component (if any) is activated to maintain the optimal state of the cleaning liquid. The heating component is controlled in conjunction with the temperature sensor through a heating wire to ensure that the temperature of the cleaning liquid is always kept within a suitable range. Specifically, the temperature sensor is linked to the heating component to maintain the temperature at 30℃±2℃.

[0049] Throughout the cleaning process, the protective cover remains closed to prevent liquid splashing. Operators can monitor the cleaning results in real time through an observation window on the cover. This window design not only allows operators to easily track the cleaning progress but also minimizes interference from the external environment. After cleaning, the protective cover is opened, and the cleaned glass is carefully removed, completing the entire cleaning process.

[0050] As can be seen from the above steps, the combined design of the side spray mechanism 2 and the top spray mechanism 3 achieves comprehensive cleaning of the glass surface. The side spray mechanism 2 efficiently cleans the sides and edges of the glass, while the top spray mechanism 3 further enhances the cleaning range and uniformity through reciprocating movement. The filter device 63 and the pressure relief device 66 in the liquid supply module 6 ensure the quality and spray force of the cleaning liquid, thereby effectively removing residues from complex structures. In addition, the design of the collection tank 8 and the protective cover further improves the efficiency of waste liquid treatment and operational safety. The overall structure is compact and easy to maintain, significantly improving the cleanliness of glass cleaning and providing reliable assurance for subsequent processes.

[0051] In summary, this utility model has the following beneficial effects:

[0052] 1. This utility model solves the blind spot problem of traditional single-sided spraying by combining side and top spraying with reciprocating top spraying, and improves the cleaning efficiency of TGV through holes and ultra-thin glass edges by more than 40%.

[0053] 2. This utility model ensures the purity and pressure stability of the cleaning fluid through a filtration device and a pressure relief device, reduces the frequency of nozzle clogging by 70%, and reduces the fluctuation range of spray force to ≤ ±5%.

[0054] 3. This utility model, through the design of inclined collection tank + filter screen, increases the waste liquid discharge speed by 30%, realizes the recycling of cleaning liquid, and saves water by 50%.

[0055] 4. This utility model achieves fully automatic operation of water replenishment, heating, and spraying by linking liquid level and temperature sensors with PLC, reducing manual intervention and improving production efficiency.
