Description

Technical Field

[0001] This invention relates to the field of glass processing technology, and in particular to a processing method for AG anti-glare glass. Background Technology

[0002] Anti-glare glass (AG) is a type of glass that undergoes a chemical process to transform its reflective surface into a matte, diffuse reflective surface. This reduces ambient light interference and provides excellent anti-reflective properties and light transmission, making it widely used in display devices, touchscreens, and optical components. However, the processing of AG glass, especially the chamfering and drilling stages, is challenging due to the material's inherent hardness and brittleness, making it prone to cracking and chipping, which negatively impacts the product's aesthetics and performance. Currently, AG glass edge chamfering primarily employs three methods: laser chamfering, mechanical chamfering, and sandblasting. Laser chamfering utilizes a laser to precisely heat and melt the edges of the AG glass, and by controlling the laser's path and speed, it achieves efficient and precise edge chamfering, minimizing the risk of cracking and chipping. However, the high cost of laser equipment and the complexity of operation increase the overall processing cost. Mechanical chamfering uses mechanical cutting tools, such as grinding heads or milling cutters, to cut and chamfer the edges of AG glass. It offers high processing precision and is suitable for AG glass of various sizes and shapes. However, this method requires precise control of cutting parameters and paths to ensure chamfer quality and accuracy, demanding a high level of operator skill. Sandblasting chamfering uses high-speed moving abrasive particles to impact and cut the edges of AG glass, forming the desired chamfer shape. It has low processing costs, is easy to operate, and is suitable for mass production. However, this method requires control of sandblasting parameters and paths, and the chamfer accuracy is not as high as laser and mechanical chamfering. It is also more prone to producing minor imperfections, which can damage the glass.

[0003] Chamfering of holes in AG glass mainly employs three methods: mechanical drilling followed by chamfering, integrated laser drilling and chamfering, and sandblasting. Mechanical drilling followed by chamfering first uses mechanical drilling equipment to drill the required hole in the AG glass, then uses a chamfering tool to chamfer the edge of the hole. This method is suitable for chamfering holes in larger diameter and thicker glass, offering high processing precision. However, it requires two processing steps, resulting in lower processing efficiency and potentially increasing the risk of cracking and edge chipping. Integrated laser drilling and chamfering uses a laser beam to thermally process the glass, causing localized melting, evaporation, or vaporization to form a through hole. The laser beam then heats the hole opening after drilling, causing localized melting and flow of the glass to form a chamfer. This method is efficient and precise, completing drilling and chamfering in a single process, reducing the risk of cracking and edge chipping. However, it requires expensive equipment, is complex to operate, and demands high operator skills. Sandblasting chamfering uses high-speed sand particles to impact and cut the edge of the hole to form the desired chamfer shape. It is low-cost and easy to operate, and is suitable for applications where the chamfering accuracy requirements are not high. However, its chamfering accuracy is relatively low, and it is prone to producing minor defects, which may affect the accuracy and size of the hole. Summary of the Invention

[0004] Therefore, it is necessary to provide a processing method for AG anti-glare glass that has high processing accuracy and efficiency, low product breakage rate and processing cost, and low skill requirements for operators, in order to address the above-mentioned shortcomings.

[0047] To make the above-mentioned objects, features, and advantages of the present invention more apparent and understandable, specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings. Many specific details are set forth in the following description to provide a thorough understanding of the present invention. However, the present invention can be practiced in many other ways different from those described herein, and those skilled in the art can make similar modifications without departing from the spirit of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0048] Please combine Figure 1-4 as well as Figure 11 This invention discloses a processing method for AG anti-glare glass that features high processing precision and efficiency, low product breakage rate and processing cost, and low skill requirements for operators. The processing method for AG anti-glare glass includes the following steps:

[0049] S1. Sandblast the incoming glass material to form a sandblasted surface 110 on the front side of the glass and a non-sandblasted surface 120 on the back side of the glass.

[0050] Specifically, the incoming glass is large-format, non-grindable glass. Before the incoming glass is transported into the sandblasting area of ​​the sandblasting machine, the protective film on the surface of the glass to be sandblasted needs to be removed, while the protective film (bottom film 130) on the parts of the glass that do not need to be sandblasted is retained. Then, the glass is loaded into a fixture driven by a transmission mechanism, with the side of the glass with the protective film removed facing up (i.e., facing away from the fixture), and the part of the glass with the protective film not removed is in contact with the fixture to prevent the glass surface from being scratched by the fixture, thus protecting the non-sandblasted surface 120 of the glass.

[0051] Before sandblasting, the fixture carrying the glass moves within the working transport plane under the drive of the transmission mechanism. A sandblasting machine, suspended above the glass material working transport plane, sandblasts the glass on the fixture, ensuring that the nozzle of the sandblasting machine spans the width of the glass to cover the entire glass surface. Simultaneously, the working parameters of the sandblasting machine, such as sandblasting pressure, sandblasting distance, and sandblasting angle, are set to achieve the best sandblasting effect. In step S1, the sandblasting abrasive is diamond grit; the sandblasting pressure of the incoming glass is 0.1-0.7 MPa; the abrasive particle size is 0.2-0.5 mm to ensure uniform sandblasting without excessive damage to the glass surface; the sandblasting speed is 20-30 m / s to maintain stable sandblasting pressure and efficiency; the sandblasting angle (the angle between the sandblasting gun and the glass surface) is 45°-90° to optimize the sandblasting effect and uniformity; and the sandblasting distance is 10-30 cm. Preferably, the sandblasting distance is 20cm and the sandblasting angle is 90°. In other embodiments, the sandblasting parameters of the sandblasting machine can be adjusted according to product requirements, glass material, and sand / water material.

[0052] During sandblasting, the sandblasting machine is started, and the water jet 200 of the spray gun performs high-speed sandblasting on the glass moving on the working transport plane. During sandblasting, it is necessary to ensure that the vast majority of the spray points land on the un-sandblasted glass surface below the spray gun nozzle, while the sandblasted glass continues to move in front of the spray points. This method achieves horizontal linear impact with the glass moving and the spray gun remaining stationary, improving sandblasting uniformity and efficiency. In this embodiment, after sandblasting, the roughness of the glass surface 110 is Ra 0.5-1.0μm to meet subsequent processing requirements.

[0053] S2. Cut the sandblasted glass to form several glass sheets.

[0054] Specifically, step S2 includes:

[0055] S21. Apply protective oil 140 or cover with a protective film to the frosted surface 110 of the glass. In step S21, the viscosity of the protective oil 140 is 20-50 cps to ensure that the protective oil 140 is evenly applied by roller and is easy to remove. In this embodiment, the protective oil 140 can be ink. The protective oil 140 is applied to the frosted surface 110 of the glass by roller coating 300 or spraying with a spray gun, or a protective film is covered on the frosted surface 110 of the glass to prevent the glass from being scratched during subsequent handling or processing.

[0056] S22. Cut the glass into several glass sheets. In step S22, a cutting wheel or laser is used to cut the glass, so that the large-format glass 100 is cut into several small glass sheets, which facilitates the processing of each small glass sheet individually to obtain a product of the corresponding size. During the cutting process, it should be ensured that the cutting edges are flat and free of obvious cracks. Subsequently, the protective film on the non-sanded surface 120 of the glass is removed, and the non-sanded surface 120 of the glass sheet is cleaned to remove dust or impurities. In addition, in this solution, the large-format glass 100 is sandblasted as a whole first, and then the sandblasted glass is cut into sheets, which can realize batch sandblasting of glass sheets to improve the sandblasting efficiency of glass sheets.

[0057] S3. A laser beam 400 is injected from the non-frosted surface 120 of the glass plate, causing the interior of the glass plate to be engraved by laser to form a chamfer pretreatment area, a hole pretreatment area, and a hole chamfer pretreatment area. The chamfer pretreatment area, hole pretreatment area, and hole chamfer pretreatment area are collectively referred to as the laser modification area 150.

[0058] After the AG glass is sandblasted to form a frosted surface 110, diffuse reflection occurs when a laser beam acts on the frosted surface 110, causing the laser energy incident on the glass to attenuate, severely affecting the glass processing quality. In this solution, the laser beam 400 is incident from the non-frosted surface 120 of the glass into the glass for laser pretreatment to treat the glass edges and holes. This effectively solves the processing quality problems caused by diffuse reflection and prevents product edge chipping. Specifically, when the laser beam 400 is incident from the non-frosted surface 120 of the glass sheet, firstly, the high smoothness of the non-frosted surface 120 helps the laser beam 400 to be better focused on the cutting path, thereby improving cutting accuracy; secondly, while solving the diffuse reflection problem caused by the frosted surface 110, the small laser spot and high energy density allow for precise focusing, ensuring the flatness and dimensional accuracy of the cut edges. Secondly, during laser cutting, because the laser beam 400 moves relative to the material along a certain trajectory and forms a fixed-shape kerf, the smoothness of the non-abrasive surface 120 allows the heat generated during laser cutting to be distributed more evenly in the cutting area. This helps reduce the heat-affected zone on the glass sheet, decreases workpiece deformation, and maintains the smoothness and aesthetics of the cut surface, thus improving cutting quality. Thirdly, compared to the abrasive surface 110, the non-abrasive surface 120 has weaker scattering, reducing laser scattering losses during the incident process. This allows more laser energy to be effectively utilized in the cutting process, improving cutting efficiency and energy utilization. Furthermore, laser cutting has transmission characteristics. When a laser cutting machine is equipped with multiple CNC worktables, CNC operation can be achieved. For the non-abrasive surface 120 of the glass sheet, laser cutting can more easily achieve automated and intelligent control, reducing manual intervention and improving production efficiency and consistency. Figure 5 The image shows a comparison of the effects of laser beam incident from a non-sand surface and from a sand surface on a glass slide. It can be seen that the laser cutting marks after the laser beam incident from the non-sand surface are significantly more regular and complete than those after the laser beam incident from the sand surface. Figure 6 This illustrates the chamfering effect on a glass sheet when the laser beam is incident from both the frosted and non-frosted surfaces. Because the laser beam incident from the frosted surface affects the real-time laser focus compensation function, the chamfer is not centered on the glass. Figure 6 As can be seen, when the laser beam is incident on the sand surface, the chamfer position shifts, which will cause product defects.

[0059] Please combine Figure 7In this scheme, a laser engraving machine is used to perform laser engraving on the glass sheet. When using a laser beam to perform laser engraving on the glass sheet, the laser beam emitted by the laser 101 of the laser engraving machine passes through a half-wave plate 102, which changes the polarization state of the laser. The beam control unit 103 further controls the shape of the laser beam to obtain a contour beam, adapting to the final shape required for the laser-cut area on the glass sheet. This contour beam, after being reflected by the mirror 104, is incident on the glass sheet mounted in the fixture on the transmission mechanism 105 to perform laser engraving on the glass sheet. The beam control unit 103 can be one of a Bezier cutting head, a diffractive optical element (DOE) lens, or a spatial light modulator (SLM), and is equipped with a focusing objective lens to achieve processing of different thickness chamfer sizes. By using a Bezier cutting head, a DOE (Diffractive Optical Element) lens, or a SLM (Spatial Light Modeling Element), the shape and energy distribution of the laser beam can be altered, enabling the laser beam to be shaped in a laser engraving machine. The shaped laser beam allows for precise control of its focal point and depth, suitable for complex internal engraving or fine surface processing. The beam control unit 103 shapes the laser beam into the desired chamfered or circular shape, then focuses it onto the interior of the transparent glass, engraving it in a multi-focal manner in a single operation to create edge chamfers, holes, and hole chamfers within the glass. The chamfer and hole shapes can be arbitrarily set and finely adjusted according to the final product performance. Laser focusing and engraving refers to the shaped laser beam being focused onto the interior of the transparent glass. Through precise focusing, the laser can perform multi-focal engraving in a single operation within the glass, creating complex designs and patterns without damaging the glass surface. Laser engraving technology is used to form chamfers and holes inside the glass sheet. The specific shape of the chamfers and holes can be adjusted according to the final performance and requirements of the product. The shape and depth of laser engraving can be flexibly set according to different application needs to achieve the best visual effect and physical properties. More preferably, in step S3, the laser beam power is 50-100W, the frequency is 50kHz-250Hz, and the chamfering speed is 5-100mm / s to maintain stable chamfering quality and efficiency. Additionally, during the laser pretreatment of the glass sheet, the glass sheet with the sandblasted side covered by protective oil or film should be placed face down on the fixture to avoid scratching the glass sheet.

[0060] S4. Place the glass slide into the etching solution for chemical etching.

[0061] In this scheme, before step S4, the protective oil or protective film on the surface of the glass slide is removed to expose both the sanded and non-sanded surfaces, allowing for full contact between the glass slide and the etching solution. The glass slide is then cleaned to remove any residual protective oil or adhering dust and impurities. During etching, the glass slide is completely immersed in the etching solution, and the sanded surfaces, laser-pretreated edges, and holes are chemically etched simultaneously to improve etching efficiency. Chemical etching reduces the thickness of the glass slide, exposing the chamfers, holes, and chamfered edges formed by laser engraving. This facilitates the etching solution's penetration into the gaps within these structures, allowing the etching solution to react with the glass slide within these gaps, creating communication between the inner and outer surfaces. This provides conditions for subsequent cleaving operations and reduces the difficulty of cleaving. Preferably, in step S4, the glass slide is placed in a concentrated NaOH or KOH solution with a mass fraction greater than 50% and a temperature higher than 120°C for chemical etching. Furthermore, during the chemical etching of glass slides, a bubbling device can be added to promote the circulation of the high-temperature etching solution. Please refer to... Figure 8 and Figure 9 After the glass slide is liquid polished (chemically etched), the excess material at the chamfers on the front and back of the glass slide has been removed, leaving only the waste material at the product body position connected to the product. Figure 10 The image shows a comparison of the effects of AG anti-glare glass on a sanded surface and a non-sanded surface after liquid polishing.

[0062] S5. Crack the glass sheet to create a chamfer at the edge.

[0063] In step S5, the glass slide is cleaved using a CO2 laser, liquid nitrogen, or ice-water quenching method. Specifically, when using a CO2 laser, the CO2 laser beam is controlled to scan once along the existing cutting and modification trajectory at the edge of the glass slide. Utilizing the high energy of the laser, continuous high-temperature oscillations are applied to the surface of the object, inducing stress cracks and ultimately achieving the cleaving purpose, causing the waste material at the edge of the glass slide to automatically detach. The parameters for CO2 laser cleaving are: power 30W-200W, cleaving speed 20mm / s-200mm / s, and laser frequency 500kHz-5000kHz. When using liquid nitrogen for cleaving, a liquid nitrogen sprayer is used to spray liquid nitrogen from the storage tank onto the surface of the glass slide after liquid polishing. Upon contact with the liquid nitrogen, the glass slide cools rapidly, altering the internal stress. Since the chamfered edges of the glass slide have been pre-treated with laser engraving, stress cracks will form in these areas as the glass slide cools, ultimately achieving the cleaving purpose and causing the waste material from the glass slide to automatically detach. Furthermore, because the ambient temperature for chemical etching in this method is above 120°C, the glass slide can be quickly lifted into ice water at the end of liquid polishing, causing rapid cooling. The cracks on the glass slide extend rapidly along the laser engraving locations, achieving cleaving through ice water.

[0064] S6. Use an ultrasonic underwater cleaver to create holes in the glass slide, so that holes are formed in the pre-treated area and the chamfered area of ​​the glass slide.

[0065] Since the waste material at the center of the holes on the glass sheet is not removed after chemical etching, further processing of this waste material is required. Specifically, in this solution, when using ultrasonic underwater cleaving to cleave the glass sheet, the ultrasonic generator transmits ultrasonic vibration energy to the glass sheet through a liquid medium. This vibration energy generates stress concentration inside the glass, ultimately causing the glass to fracture along the predetermined cutting line. This causes the laser-engraved portion of the hole area on the glass sheet to fracture, thus removing the waste material at the center of the hole and achieving the purpose of hole cleaving. Using ultrasonic underwater cleaving to cleave glass sheets allows for batch processing of glass sheets, resulting in high efficiency. Furthermore, the liquid's buffering effect reduces scratches and edge chipping, improving production quality. In addition, ultrasonic underwater cleaving technology ensures uniform stress on the glass material during the cleaving process, reducing crack displacement or irregular fracture caused by stress concentration, thereby improving the quality and efficiency of cleaving. Figure 12 The image shows a comparison of the effects of AG anti-glare glass before and after the hole splitting process. It can be seen that after using ultrasonic underwater splitting, the waste material in the center of the hole on the glass sheet is evenly cut off, resulting in a smooth hole on the glass sheet.

[0066] After liquid polishing, the silicate mixture in the strong alkaline solution becomes embedded in the crevices formed by laser engraving on the glass slide. This results in white powdery solids adhering to the edges and chamfers of the glass, requiring cleaning to prevent interference with subsequent processes. The adhesion of this white powdery solids is as follows: Figure 13-16 As shown. To address this issue, in step S6, the glass slide is placed in a 1%-30% citric acid solution or a 1%-20% NaOH solution for ultrasonic underwater cleaving. In this solution, the citric acid solution or NaOH solution is used as the liquid for ultrasonic underwater cleaving. The citric acid solution or NaOH solution can remove the silicates generated on the glass slide at the original laser-engraved areas after chemical etching, so as to achieve the purpose of cleaning the glass while cleaving the holes, thereby improving work efficiency. The effect of ultrasonic underwater cleaving of the glass slide in the citric acid solution or NaOH solution is as follows. Figure 17-18 As shown, the glass slide has a high degree of cleanliness. After the glass slide was cracked, it was cleaned again to remove any chemical residues on its surface. Figure 19 The image shows a cross-sectional view of the finished AG anti-glare glass. It can be seen that the non-sand-like surface of the glass sheet has a high degree of smoothness, and its chamfers are flat and uniform.

[0067] When using the aforementioned ultrasonic underwater cleaving technique to cleave glass slides, firstly, during the ultrasonic cleaving process, a separating film adheres to the material's surface, isolating the material from the liquid and preventing displacement due to liquid flow. Simultaneously, due to the adhesive force of the separating film, the positions of multiple independent parts are fixed by the film's bonding effect, helping to improve the material's positioning accuracy. Secondly, the ultrasonic generator transmits ultrasonic waves to the material through the liquid, cleaving it. Due to the mechanical action of the ultrasonic waves, the cleaving process is ensured to be more uniform and controllable, thereby improving the cleaving quality. Thirdly, ultrasonic underwater cleaving technology is applicable to various types of glass materials, without limitations on material thickness or shape, exhibiting strong adaptability and flexibility. Furthermore, ultrasonic underwater cleaving technology allows for mass production, reducing manual intervention and improving production efficiency.

[0068] The processing method of the AG anti-glare glass of the present invention has at least the following beneficial effects:

[0069] 1) Laser engraving is used to pre-process the glass sheet. By shaping the laser beam, the position of the laser engraving can be precisely controlled, realizing efficient and precise processing of AG glass, improving processing accuracy and yield.

[0070] 2) The laser beam enters from the non-sanded surface of the glass sheet, reducing the damaged area of ​​the AG glass, reducing cracks and edge chipping during processing, and lowering the breakage rate;

[0071] 3) Combining sandblasting and laser processing of large-format glass sheets with batch etching and hole / crack processing of glass sheets enables rapid and efficient processing of AG glass, improving production efficiency.

[0072] 4) By optimizing the processing flow, waste and losses during processing are reduced, processing costs are lowered, and the skill requirements for operators are low, thus reducing the difficulty of product processing.
