Description

Technical Field

[0001] The present invention relates to the field of integrated processing of frosted glass, and particularly to a processing method, system, equipment and medium for frosted glass. Background Art

[0002] Traditional glass processing methods usually adopt a single process such as mechanical grinding. Mechanical chamfering is prone to generate microcracks (depth > 10 μm) and residual stress (> 50 MPa), resulting in a decrease in the impact resistance of the glass. Mechanical drilling is prone to generate chipping (chipping width > 50 μm), and additional processes need to be added to process cracks, chipping, etc., increasing the time cost and thus reducing the production efficiency.

[0026] On the other hand, the present invention also provides a processing system for sandblasted glass, including a pretreatment module, a chamfering module, a detection module, a repair module, and an etching module, wherein,

In addition, the glass substrate is first sandblasted, and then the sandblasted glass is modified by using a multi-focus profiling beam to form the required shape. Since the sandblasting treatment increases the transparency of the glass, the generated diffuse reflection will not affect the modification of the glass by the multi-focus profiling beam, and the process step of eliminating the diffuse reflection can be omitted, simplifying the process flow and shortening the processing time, thereby improving the production efficiency.

[0047] In some embodiments, such as Figure 1 andFigure 2 As shown Figure 1 is a step - flow chart of a processing method for sand - blasted glass, Figure 2 is an execution flow chart of a processing method for sand - blasted glass. The processing method for sand - blasted glass provided by the present invention includes the following steps:

[0048] S100. Pretreat the glass substrate to obtain the glass to be modified.

[0049] Among them, the pretreatment includes but is not limited to sand - blasting treatment and / or cutting. If mechanical cutting is adopted, the order of the steps of sand - blasting treatment and cutting is not limited. It can be sand - blasted first or cut first. If laser cutting is used, it can be sand - blasted first and then cut, which can reduce the influence of diffuse reflection.

[0050] Specifically, the sand - blasting treatment specifically includes tearing off the protective film on one side of the large - format non - grinding glass of the raw material and performing sand - blasting treatment to form a uniform fine rough structure. The pressure of the sand - blasting treatment can be 0.4 - 0.7 MPa, for example, 0.5 MPa, and the time of the sand - blasting treatment can be 1 - 10 min, for example, 40 - 80 seconds.

[0051] After the sand - blasting treatment, the haze of the glass surface is < 32%, for example, 27.4%, and the surface roughness Sa < 400 nm. The influence of diffuse reflection can be ignored. As shown in Table 1, Table 1 shows the haze and surface roughness of the glass surface after 6 kinds of sand - blasting treatments.

[0052] Table 1

[0053]

[0054] Cutting specifically includes the following steps: scribing the large - format non - grinding glass after sand - blasting treatment with a glass cutter wheel, and then performing mechanical chipping to cut it into at least two small glasses to be modified. In some embodiments, the large - format non - grinding glass after sand - blasting treatment can also be cut by laser to form at least two small glasses to be modified.

[0055] S200. Modify the glass to be modified with a multi - focus profiling beam to form a first preset shape and obtain the modified sand - blasted glass.

[0056] Among them, the multi - focus profiling beam can be but is not limited to a laser that forms multiple foci on the glass, including but not limited to nanosecond laser. The multiple foci specifically refer to more than two. As Figure 3 shown Figure 3 is a distribution schematic diagram of the multi - focus profiling beam on the glass. The vertical coordinate on the right represents the color value.

[0057] The number of foci of the multi-focus profiling beam on the glass is more than 40, such as 40 - 80, and the power of the multi-focus profiling beam is more than 50W, such as 50 - 80W.

[0058] The first preset shape may include but is not limited to chamfers, and the chamfers include edge chamfers and chamfers of through-holes.

[0059] Among them, the modification includes but is not limited to cutting or ablation.

[0060] Specifically, if only chamfers need to be formed, but not limited to, a multi-focus profiling beam with more than 40 foci and a power of more than 50W can be used to modify the glass to be modified to form edge chamfers or chamfers of through-holes, obtaining the modified frosted glass. For example, a multi-focus profiling beam with a power of more than 50W, a focal point spacing of 2 - 6um, a pulse width of 1 - 6ps, and a frequency of 20 - 100kHz is used to modify the glass to be modified to form edge chamfers or chamfers of through-holes, obtaining the modified frosted glass.

[0061] As Figure 4 shown, Figure 4 is a schematic structural diagram of a through-hole and a chamfer of a through-hole. Figure 4 In the above two figures, they are cross-sectional views of the glass along the thickness direction, and the bottom figure is a schematic diagram of the glass surface. If through-holes also need to be formed and chamfers of through-holes are formed on the through-holes, the edge chamfers can be first formed by the aforementioned method, and then a multi-focus profiling beam with a laser power of 15 - 25W is used to irradiate the glass for 0 - 6 seconds to form chamfers of through-holes, obtaining the frosted glass with chamfers of through-holes; then, the profiling beam is used to scan the through-hole traces at a scanning speed of 5 - 100mm / s, and a single-focus Gaussian laser with a laser power of 20 - 30W is used to ablate through-holes along the scanned traces, obtaining the modified frosted glass. Among them, the order of forming edge chamfers, chamfers of through-holes, and through-holes can be alternated.

[0062] It should be noted that in the case of both forming chamfers and through-holes, in step S200, chamfers and through-holes can be formed according to the above steps, or chamfers can be first formed in step S200, and after step S400, through-holes can be formed on the repaired frosted glass.

[0063] The laser control method for forming through-holes can be to use infrared nanosecond laser to ablate the glass according to a spiral rising scanning path to remove the waste glass at the center of the through-hole to form through-holes.

[0064] S300. Use machine vision to detect the sandblasting leakage points of the modified frosted glass to obtain the leakage point detection result.

[0065] Among them, the leakage point detection result includes but is not limited to the number, position, and area of sandblasting leakage points.

[0066] Among them, machine vision can be, but is not limited to, one or a combination of multi-scale template matching method, adaptive threshold segmentation method, and frequency domain analysis method. Among them, the multi-scale template matching method includes: pre-establishing a standard sandblasting texture template, calculating the similarity through the Normalized Cross Correlation (NCC) algorithm, detecting local texture missing areas, and obtaining sandblasting leakage points.

[0067] The adaptive threshold segmentation method includes: using the Otsu algorithm or local adaptive threshold, such as the Contrast Limited Adaptive Histogram Equalization (CLAHE) algorithm, to separate sandblasting leakage points from the background, combining morphological closing operation to eliminate noise, and detecting sandblasting leakage points.

[0068] Frequency domain analysis: Perform Fourier transform on the sandblasting texture, suppress high-frequency noise through a band-stop filter, enhance the low-frequency features of the leakage point area, and detect sandblasting leakage points.

[0069] Machine vision can also use existing visual deep learning models, including lightweight segmentation network: adopting the Mobile-Unet model (encoder based on MobileNetV3 + U-Net decoder), and real-time outputting the pixel-level mask of sandblasting leakage points. Object detection model: Deploy YOLOv8-Nano, and label sandblasting leakage points as the "dot defect" category during training, balancing the detection speed (≥30FPS) and accuracy (mAP≥0.9). Anomaly detection model: Unsupervised learning based on Autoencoder, and locating uneven sandblasting areas through reconstruction error (applicable to scenarios with a small amount of labeled data).

[0070] S400. Repair the sandblasting leakage points of the modified frosted glass according to the leakage point detection results to obtain the repaired frosted glass.

[0071] Among them, the method of leakage point repair can be laser dotting on the modified frosted glass according to the leakage point detection results to obtain the repaired frosted glass.

[0072] Specifically, during repair, the pressure of sandblasting repair can be, but is not limited to, 0.5 - 0.7MPa, and the time of sandblasting repair can be, but is not limited to, 40 - 80s. The laser power of laser dotting can be, but is not limited to, 8 - 20W, and the repair speed can be, but is not limited to, 1 - 3 seconds / point.

[0073] Optionally, in some embodiments, the leakage point detection results include the positions of sandblasting leakage points, and step S400 specifically includes:

[0074] S410. Take the position of the sandblasting leakage point as the input of the optimization algorithm, and take the shortest total length of the repair path as the optimization goal of the optimization algorithm to obtain the repair path.

[0075] Among them, the optimization algorithm includes but is not limited to genetic algorithm, ant colony algorithm or dynamic programming algorithm, etc.

[0076] Specifically, taking the genetic algorithm as an example, a group of initial paths can be obtained according to the position of the sandblasting leakage point, and the initial paths are used as the initial population of the genetic algorithm. Taking the total length of each path as the fitness of each species (each path), continuously update and iterate until the number of iterations meets the requirements or the fitness meets the conditions, end the iteration, and obtain a path with the shortest total length as the repair path.

[0077] In some embodiments, the genetic algorithm can update the repair path in real time. For example, first obtain the initial repair path according to all the sandblasting leakage points. When repairing the first sandblasting leakage point, the repair path can be re-planned according to the remaining sandblasting leakage points according to the aforementioned rules.

[0078] S420. Repair the sandblasting leakage points of the modified frosted glass according to the repair path to obtain the repaired frosted glass.

[0079] Specifically, move the laser or the sandblasting head to repair according to the sequence of the sandblasting leakage points on the repair path to obtain the repaired frosted glass. The idle running time of the laser head can be reduced, and thus the repair time can be reduced.

[0080] If the repair path is updated in real time in step S410, repair the sandblasting leakage points of the modified frosted glass according to the latest repair path.

[0081] In some embodiments, the repair path of the present invention can be planned according to the area of the sandblasting leakage points. According to the greedy algorithm, sort the sandblasting leakage points from large to small in area, and give priority to repairing the sandblasting leakage points with large sizes and the path with the shortest total length as the repair path.

[0082] S500. Chemically etch the repaired frosted glass to form the final frosted glass.

[0083] Specifically, if only edge chamfers need to be formed, step S500 specifically includes:

[0084] Use the etching solution to chemically etch the repaired frosted glass along the shape of the chamfer and the through hole for more than 50 seconds to form the final frosted glass, for example, perform chemical etching for 1-2 minutes. Among them, the etching solution can be but is not limited to hydrofluoric acid.

[0085] For example, the repaired frosted glass is chemically etched with hydrofluoric acid for 1-2 minutes to form the final frosted glass.

[0086] If in addition to the edge chamfer, such as Figure 5 As shown, Figure 5 This is a schematic diagram of a final frosted glass, and a through hole or a through hole chamfer needs to be formed. Step S500 specifically includes:

[0087] The repaired frosted glass is chemically etched for more than 1 minute using an etching liquid along the shape of the chamfer and the through hole to form the final frosted glass. For example, the chemical etching is performed for 1.5-2.5 minutes. The etching liquid may be, but is not limited to, hydrofluoric acid.

[0088] For example, the repaired frosted glass is chemically etched for 1.5-2.5 minutes using hydrofluoric acid along the shapes of chamfers and through holes to form the final frosted glass.

[0089] Chemical etching can form an anti-glare functional surface, remove glass stress, remove microporous waste and stress, and allow the etching liquid to chemically react along the modified shape. After chemical etching, the glass shape is cracked and cleaned.

[0090] In some embodiments, before performing chemical etching, the aforementioned method further includes:

[0091] A Gaussian beam is used to ablate a second preset shape on the glass to be modified.

[0092] or

[0093] A third preset shape is ablated on the repaired frosted glass using a Gaussian beam.

[0094] The Gaussian beam can be but is not limited to a single-focus laser, including but not limited to a single-focus infrared nanosecond laser. Specifically, a single-focus Gaussian beam is used to ablate a through hole or pattern on the repaired frosted glass or the glass to be modified along the modification trace.

[0095] The second preset shape includes but is not limited to a preset pattern or a preset through hole, a groove, or a micro hole, and the third preset shape includes but is not limited to a preset pattern or a preset through hole, a groove, or a micro hole. There is no limitation on the preset pattern.

[0096] Combined with the aforementioned step S200, it can be known that through holes can be ablated on the glass to be modified, through holes can be ablated on the frosted glass after repair, or a portion of through holes can be ablated on the glass to be modified, and then the remaining through holes can be ablated on the frosted glass after repair, and then chemical etching can be performed. By expanding the processing shapes (patterns, through holes), product diversity can be improved.

[0097] The present invention also has the following beneficial effects:

[0098] The present invention uses a multi-focus profiling beam to modify the glass, which can reduce the stress generated by mechanical modification, thereby reducing cracks and edge collapse. In addition, the glass substrate is first sandblasted to create a surface condition that is both transparent and receptive to specific laser modification, and the transparency and diffuse reflection characteristics of the glass after sandblasting are cleverly utilized. The multi-focus profiling beam is then used to modify the sandblasted glass to form a required shape, which can omit the process step of eliminating diffuse reflection, simplify the process flow, shorten the processing time, and improve production efficiency.

[0099] In order to better explain the technical solution of the present invention, the present invention provides another specific embodiment as follows:

[0100] This embodiment describes in detail the integrated processing technology for 0.5 mm thick ultra-thin frosted glass, which integrates multiple key steps including precision sandblasting, laser cutting and separation, laser modification, machine vision detection of sandblasting leaks and sandblasting leak repair, chemical etching and protective treatment, and final inspection and special packaging.

[0101] Raw material preparation and precision pretreatment: The glass substrate selected is 0.5mm thick ultra-thin large-format non-grinding glass, and the surface is covered with PET protective film (polyester film). Use 0.05mm diameter fine sand powder for slight sandblasting to ensure uniform and delicate frosting effect, while reducing the damage of large-format non-grinding glass.

[0102] Laser cutting and fine separation: The laser of the cutting machine is used to cut the large-format non-grinding glass after sandblasting with high precision and low energy density. Subsequently, the non-grinding glass at the cutting line is naturally separated by the thermal stress induced by the laser to form several pieces of glass to be modified. This process pays special attention to controlling the laser parameters to reduce the deformation or cracking of the glass due to excessive heat-affected zone.

[0103] Laser modification and micro-hole chamfer modification: Customized diffractive optical elements are used to generate a fine multi-focus profiling beam with 40 focal points. The multi-focus profiling beam acts on the inside of the glass to be modified with low energy density and precise control to form a 45° edge chamfer.

[0104] Machine vision inspection and fine repair: A high-resolution microscope combined with an image recognition algorithm is used to conduct a detailed inspection of the modified frosted glass. Once a sandblasting leak or a tiny defect is detected, the micro-repair program is immediately started, using a low-power infrared laser to perform local dot repairs and punch a micro-hole with a diameter of 0.6mm at the designated location.

[0105] Chemical etching and protective coating: A hydrofluoric acid solution is used for short-term chemical etching to enhance the anti-glare performance and achieve edge waste chipping. Subsequently, an extremely thin transparent scratch-resistant coating is applied to protect the glass surface from scratches and contamination.

[0106] Final inspection and special packaging: A comprehensive quality inspection is carried out. After passing the inspection, shock-proof and scratch-resistant packaging materials are used to ensure the safety of the glass sheets during transportation and storage.

[0107] To better explain the technical solution of the present invention, another specific embodiment of the present invention is provided as follows:

[0108] This embodiment processes frosted glass with a special shape (such as a circle) to verify the applicability and flexibility of the present invention in the processing of special-shaped glass.

[0109] Raw material preparation and pretreatment: The glass substrate is a circular non-ground glass with a thickness of 1 mm, and its surface is covered with a PVC protective film (polyvinyl chloride film). During the sandblasting stage, after removing the protective film, the surface of the circular non-ground glass is evenly sandblasted with ceramic particles with a diameter of 0.18 mm.

[0110] CNC cutting and mechanical chipping: A five-axis CNC cutting machine is used to cut the sandblasted circular non-ground glass according to a preset circular pattern. Subsequently, through a mechanical chipping device, the circular glass sheets are separated from the circular non-ground glass in a non-contact manner to obtain several small circular glass pieces to be modified.

[0111] Laser modification treatment: A customized diffractive optical element is used to generate a multi-focus profiling beam suitable for the circular glass edge, which contains 48 focal points. The multi-focus profiling beam acts on the inside of the glass to form a uniform 45° edge chamfer.

[0112] Machine vision inspection and laser repair: A 3D vision inspection system is used to perform an omnidirectional scan of the entire surface of the modified circular glass to detect sandblasting leakage points. When a leakage point is detected, the laser repair program is started. Using a 50W green laser, according to the 3D coordinate information, the sandblasting leakage points are precisely repaired in the same manner as in the previous embodiment. At the same time, an infrared nanosecond laser is used to process the micropores and punch micropores with a diameter of 0.9 mm at the specified positions.

[0113] Chemical etching and polishing: A hydrofluoric acid solution containing an inhibitor is used to chemically etch the repaired circular glass, and the etching time is set to 7 minutes. After etching, through a mechanical polishing device, the edges and surfaces of the etched circular glass are polished to remove any processing marks and enhance the aesthetic appearance.

[0114] Final Inspection and Packaging: Conduct a comprehensive quality inspection on the processed round glass, including dimensions, shape, edge chamfer quality, micro-hole permeability, and surface finish, etc.

[0115] In some embodiments, as Figure 6 shown, Figure 6 is a schematic structural diagram of a frosting glass processing system.
