Description

Technical Field

[0001] This application belongs to the field of glass manufacturing technology, and specifically relates to a spraying device for the glass surface during the edge grinding process of substrate glass. Background Technology

[0002] In the production process of LCD substrate glass, the cold-end processing mainly includes the edge grinding process. This process generates a large amount of glass dust. Although most of the dust can be removed by a dust extraction device, some still adheres to the glass surface. When the dust-laden substrate glass enters the cleaning machine, it leads to an increase in surface particulate matter, severely impacting the yield rate.

[0003] Existing grinding equipment lacks an effective spray cleaning device for the glass surface during the edge grinding process, resulting in the inability to remove glass dust near the edge in a timely manner, increasing the burden on the cleaning machine. This not only reduces the cleaning effect but may also lead to scratches or secondary contamination of the glass surface, thus affecting the quality of the final product. Currently, the industry urgently needs a device that can clean the glass surface in real time during the edge grinding process to reduce dust pollution, improve cleaning efficiency, and ultimately increase product yield. Utility Model Content

[0004] The purpose of this application is to provide a spraying device for the glass surface during the edge grinding process of substrate glass. This addresses the issue mentioned in the background art where glass powder near the edge of the liquid crystal substrate glass cannot be removed in a timely manner during the edge grinding process, reducing the risk of glass dust scratching or causing secondary contamination to the glass surface.

[0005] To achieve the above objectives, this application adopts the following technical solution:

[0006] A spraying device for the glass surface during the edge grinding process of substrate glass includes a support frame and a spraying assembly disposed above the glass.

[0007] The spray assembly includes a water pump, a pure water pipeline, multiple spray nozzles, and fixing components;

[0008] One end of the water pump is connected to the pure water pipeline, and the other end of the water pump is used to connect to the water source;

[0009] Multiple spray nozzles are connected and arranged on the pure water pipeline;

[0010] The pure water pipeline is mounted on the support frame via fasteners.

[0011] In one possible implementation, the support frame includes a vertical frame and a horizontal frame;

[0012] The vertical frame is located above the glass, and the horizontal frame is mounted on the vertical frame to support the pure water pipeline.

[0013] In one possible implementation, the height of the vertical frame is adjustable.

[0014] In one possible implementation, a quick connector is also provided between the spray nozzle and the pure water pipeline;

[0015] One end of the quick connector is connected to the pure water pipeline, and the other end is connected to the spray nozzle through the fixing member.

[0016] In one possible implementation, the fastener includes a slider and a fixing bolt;

[0017] The slider is mounted on the horizontal frame by fixing bolts;

[0018] The slider is provided with a first mounting hole and a second mounting hole. The quick connector is fixed to the slider through the first mounting hole, and the spray nozzle is fixed to the slider through the second mounting hole.

[0019] In one possible implementation, the horizontal frame is provided with a groove for the slider to slide.

[0020] In one possible implementation, the number of spray nozzles is five, and the spray nozzles are respectively arranged at the four corners and the center of the glass surface.

[0021] In one possible implementation, the spray nozzle adopts an umbrella-shaped spray structure.

[0022] In one possible implementation, the pure water pipeline uses a flexible hose with a diameter of φ10mm.

[0023] In one possible implementation, the water pump controls the start and stop of the spray and the duration of the spray via a programmable logic controller.

[0024] Compared with the prior art, this application has the following beneficial effects:

[0025] This application provides a spraying device for the glass surface during the substrate glass edging process. By setting a support frame and spraying components above the glass, it achieves the function of spraying the glass surface during the substrate glass edging process. The aluminum profile support structure provides a stable mounting base for the spraying components, ensuring that the spray nozzles can be accurately aligned with the glass surface. A water pump delivers water from a water source to the spray nozzles through a pure water pipeline, achieving spraying of the glass surface, effectively washing away dust generated during the edging process, reducing dust contamination of the glass surface, and improving the efficiency of subsequent cleaning processes and product quality.

[0026] In one possible implementation, the vertical frame height is adjustable, allowing the spray assembly to adapt to substrate glass of varying thicknesses and production process requirements. For thicker glass, the vertical frame can be raised to maintain a suitable distance between the spray nozzles and the glass surface, ensuring effective spraying. For thinner glass, the vertical frame can be lowered to prevent impact damage to the glass surface from the sprayed water. Furthermore, the height of the vertical frame can be easily adjusted when changing to different sizes of edging machines or adjusting production processes, improving versatility and flexibility.

[0027] In one possible implementation, the chute provides a moving track for the slider, making the position adjustment of the spray nozzles more precise and convenient. During production, the position of the spray nozzles can be quickly adjusted by sliding the slider according to the actual size of the glass and the edge grinding condition, allowing the spraying device to better adapt to different production needs. Simultaneously, the chute is integrally formed with the horizontal frame, ensuring the strength and stability of the structure and ensuring that the slider will not shift due to water flow impact or other external forces during the operation of the spraying device.

[0028] In one possible implementation, five spray nozzles are positioned above the four corners and the center of the glass surface, providing complete coverage and ensuring effective cleaning of all areas. The corners and center are areas where dust easily accumulates during the edging process; by placing spray nozzles in these locations, dust can be more effectively washed away, reducing dust contamination of the glass surface, improving its cleanliness, and thus increasing the product yield.

[0029] In one possible implementation, the umbrella-shaped spray structure allows the sprayed water to evenly cover the glass surface, increasing the contact area between the sprayed water and the glass surface and improving the cleaning effect. Compared to a conventional columnar spray structure, the umbrella-shaped spray structure can more effectively wash away dust from the glass surface, reducing dust residue, lowering the risk of scratches and secondary contamination, and further improving product quality.

[0035] The specific embodiments of this application will be described in further detail below with reference to the accompanying drawings.

[0036] like Figure 1 and Figure 2 As shown, this application discloses a spraying device for the glass surface during the glass edging process of a substrate, which may include a support frame 1 and a spraying assembly 2 disposed above the glass.

[0037] The support frame 1 can be made of high-strength aluminum alloy, which has good rigidity and corrosion resistance.

[0038] Specifically, the support frame 1 is made of 40mm aluminum profile, and the outer dimensions of the support frame 1 are 1600*2000mm. The support frame 1 is located 800mm above the glass and does not affect the operation of other equipment.

[0039] The spray assembly 2 may include a water pump 21, a pure water pipeline 22, multiple spray nozzles 23, and a fixing component 24.

[0040] One end of the water pump 21 is connected to the pure water pipeline 22, and the other end of the water pump 21 is used to connect to the water source.

[0041] Optionally, the water pump 21 can be selected with a flow rate in the range of 8L / min-12L / min, which can stably extract pure water from the water source.

[0042] The multiple spray nozzles 23 are connected and installed on the pure water pipeline 22.

[0043] Optionally, the spray nozzle 23 is made of stainless steel, which can effectively prevent rust and clogging of the pure water pipe 22.

[0044] The spray nozzle 23 can be mounted on the support frame 1 by means of the fastener 24.

[0045] By adjusting the water pump 21, the water pump 21 draws pure water from the water source and sprays the pure water onto the glass through the pure water pipeline 22 and the spray nozzle 23, covering the surface of the glass and achieving a spraying effect on the glass surface.

[0046] In this embodiment, by setting a support frame 1 and a spray assembly 2 above the glass, the function of spraying the glass surface during the substrate glass edging process is realized. The aluminum profile support structure provides a stable mounting base for the spray assembly 2, ensuring that the spray nozzle 23 can be accurately aligned with the glass surface. The water pump 21 delivers water from the water source to the spray nozzle 23 through the pure water pipeline 22, realizing the spraying of the glass surface, effectively washing away the dust generated on the glass surface during the edging process, reducing dust contamination of the glass surface, and improving the efficiency of subsequent cleaning processes and product quality.

[0047] In one possible embodiment, the support frame 1 may include a vertical frame 11 and a horizontal frame 12.

[0048] The vertical frame 11 is located above the glass, and the horizontal frame 12 is set on the vertical frame 11. The horizontal frame 12 can support the pure water pipe 22.

[0049] In this embodiment, the vertical frame 11 and the horizontal frame 12 cooperate to provide a stable mounting platform for the spray assembly 2. The vertical frame 11, located above the glass, can lift the horizontal frame 12 and the spray assembly 2 to a suitable height, maintaining a proper distance from the glass surface to ensure effective spraying. The horizontal frame 12 supports the pure water pipe 22, ensuring it does not shake or sag during operation, thus maintaining a stable spray angle and position for the spray nozzles 23, thereby more effectively cleaning the glass surface.

[0050] In one possible embodiment, the height of the vertical frame 11 is adjustable.

[0051] Specifically, the aluminum alloy columns of the vertical frame 11 adopt a telescopic design, consisting of two layers of aluminum alloy tubes, with the inner tube sliding up and down inside the outer tube. The extension length of the inner tube can be controlled by rotating the adjustment knob on the side of the column, thereby adjusting the height of the vertical frame 11. The adjustment knob has an internal threaded structure, which moves the inner tube up and down when rotated.

[0052] In this embodiment, the height of the vertical frame 11 is adjustable, allowing the spray assembly 2 to adapt to substrate glass of different thicknesses and production process requirements. For thicker glass, the vertical frame 11 can be raised to maintain a suitable distance between the spray nozzle 23 and the glass surface, ensuring the spraying effect; for thinner glass, the vertical frame 11 can be lowered to prevent the sprayed water from causing impact damage to the glass surface. Furthermore, the height of the vertical frame 11 can be easily adjusted when changing to different specifications of edging machines or adjusting the production process, improving versatility and flexibility.

[0053] In one possible embodiment, a quick connector 25 is also provided between the spray nozzle 23 and the pure water pipeline 22.

[0054] One end of the quick connector 25 is connected to the pure water pipeline 22, and the other end is connected to the spray nozzle 23 through the fastener 24.

[0055] A quick connector 25 is installed between the spray nozzle 23 and the pure water pipeline 22. The quick connector 25 is made of stainless steel and has good sealing and corrosion resistance. One end of the quick connector 25 is connected to the pure water pipeline 22 via a thread, and the other end is connected to the spray nozzle 23 via a fastener 24.

[0056] In this embodiment, the quick connector 25 makes the installation and removal of the spray nozzle 23 very convenient. When it is necessary to replace the spray nozzle 23 or maintain the spraying device, it is not necessary to disassemble the entire pure water pipeline 22; simply loosening the quick connector 25 is sufficient to remove the spray nozzle 23, greatly shortening maintenance time and improving production efficiency. At the same time, the good sealing performance of the quick connector 25 ensures stable water flow during spraying, preventing leakage and ensuring the normal operation of the spraying device.

[0057] like Figure 3 As shown, the fastener 24 may include a slider and a fixing bolt.

[0058] The slider is mounted on the horizontal frame 12 by at least one fixing bolt. In this embodiment, the slider can be fixed to the horizontal frame 12 by two fixing bolts. The slider is not shown, and the fixing bolts are not shown.

[0059] The slider is made of aluminum alloy with an anodized surface, providing excellent wear and corrosion resistance. Both the first and second mounting holes on the slider are threaded holes. The quick connector 25 is screwed into the first mounting hole and fixed to the slider, while the spray nozzle 23 is screwed into the second mounting hole and fixed to the slider. In this embodiment, the first and second mounting holes are not shown.

[0060] The fixing bolt is made of stainless steel and securely mounts the slider onto the horizontal frame 12.

[0061] In this embodiment, the design of the slider and fixing bolts allows the installation position of the spray nozzle 23 to be adjusted on the horizontal frame 12. By loosening the fixing bolts, the slider can be moved to a suitable position, and then the fixing bolts can be tightened to fix the spray nozzle 23 in the new position. This facilitates flexible adjustment of the layout of the spray nozzle 23 according to the size of the glass and the requirements of the edging process, improving adaptability. At the same time, the first mounting hole and the second mounting hole on the slider are used to fix the quick connector 25 and the spray nozzle 23, respectively, ensuring the firmness and stability of the connection.

[0062] In one possible embodiment, the horizontal frame 12 has a groove for the slider to slide.

[0063] The width and depth of the groove are customized according to the size of the T-shaped protrusion at the bottom of the slider to ensure that the slider can slide smoothly within the groove. The surface of the groove is polished to reduce the friction when the slider slides, making it easier and more convenient to adjust the position of the spray nozzle 23. The groove is shown in the embodiment of this application.

[0064] In this embodiment, the chute provides a moving track for the slider, making the position adjustment of the spray nozzle 23 more precise and convenient. During production, the position of the spray nozzle 23 can be quickly adjusted by sliding the slider according to the actual size of the glass and the edge grinding condition, allowing the spraying device to better adapt to different production needs. Simultaneously, the chute is integrally formed with the horizontal frame 12, ensuring the strength and stability of the structure and ensuring that the slider will not shift due to water flow impact or other external forces during the operation of the spraying device.

[0065] In one possible embodiment, there are five spray nozzles 23, which are respectively arranged at the four corners and the center of the glass surface.

[0066] Specifically, four spray nozzles 23 are arranged above the four corners of the glass surface, 80mm from the edge of the glass, and another spray nozzle 23 is arranged at the center of the glass surface.

[0067] In this embodiment, five spray nozzles 23 are respectively arranged above the four corners and the center of the glass surface, fully covering the glass surface and ensuring that all parts of the glass surface are effectively sprayed and cleaned. The corners and center of the glass are areas where dust easily accumulates during the edge grinding process. By setting spray nozzles 23 in these locations, dust can be washed away more effectively, reducing dust contamination of the glass surface, improving the cleanliness of the glass surface, and thus improving the product yield.

[0068] like Figure 4 As shown, the spray nozzle 23 adopts an umbrella-shaped spray structure.

[0069] The spray nozzle 23 adopts an umbrella-shaped spray structure. The nozzle inside the spray nozzle 23 is designed with a special umbrella shape, and multiple tiny water spray holes are distributed on the surface of the nozzle. When water flows through the nozzle, it is dispersed into tiny water droplets and sprayed onto the glass surface in an umbrella-like manner.

[0070] In this embodiment, the umbrella-shaped spray structure allows the sprayed water to evenly cover the glass surface, increasing the contact area between the sprayed water and the glass surface and improving the cleaning effect. Compared to a conventional columnar spray structure, the umbrella-shaped spray structure can more effectively wash away dust from the glass surface, reduce dust residue, lower the risk of scratches and secondary contamination on the glass surface, and further improve product quality.

[0071] In one possible embodiment, the pure water pipeline 22 is a φ10mm hose.

[0072] Optionally, the hose is made of polyurethane. Polyurethane hoses have good flexibility, corrosion resistance, and abrasion resistance. During installation, the hose can be bent into a suitable shape as needed to facilitate the connection of the water pump 21, spray nozzle 23, and quick connector 25.

[0073] In this embodiment, the φ10mm hose has a suitable diameter, ensuring a stable water supply without causing insufficient water pressure due to an excessively large diameter or obstructed water flow due to an excessively small diameter. The hose's flexibility makes the installation of the pure water pipeline 22 more convenient and adaptable to different installation environments and layout requirements.

[0074] In one possible embodiment, the water pump 21 controls the start and stop of the spray and the duration of the spray via a programmable logic controller.

[0075] A programmable logic controller (PLC) is installed in the control system of the edge grinding machine. The PLC is connected to the water pump 21 via signal lines to control the water pump 21.

[0076] The start and stop times and duration of the spraying process are set in the programming interface of the programmable logic controller (PLC). For example, 5 seconds before the edge grinding machine starts working, the PLC controls the water pump 21 to start spraying; 10 seconds after the edge grinding machine finishes working, the PLC controls the water pump 21 to stop spraying. The duration of spraying can be adjusted according to the requirements of the edge grinding process.

[0077] In this embodiment, the start, stop, and duration of the spray are controlled by a programmable logic controller (PLC), enabling precise control of the spraying time and ensuring it matches the workflow of the edging machine. When the edging machine is operating, the spray assembly 2 is activated promptly to effectively wash away dust generated on the glass surface. After the edging machine stops operating, the spraying is stopped after a delay to ensure that any remaining dust on the glass surface is thoroughly cleaned. This improves the efficiency of the spraying device, avoids unnecessary water waste, ensures effective cleaning of the glass surface, and enhances product quality.

[0078] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this application, and are not intended to limit them; although this application has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications to the technical solutions described in the foregoing embodiments, or equivalent substitutions for some or all of the technical features, do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this application.
