[0041] All terms used in this application have the same meaning as those understood by those of ordinary skill in the art to which this application belongs, unless otherwise specifically defined. It should also be understood that terms defined in general dictionaries, such as general dictionaries, should be interpreted as having a meaning consistent with their meaning in the context of the relevant technology, and should not be interpreted in an idealized or extremely formal sense, unless explicitly defined herein.

[0042] Technologies, methods, and equipment known to ordinary technicians in the relevant art may not be discussed in detail, but where appropriate, the technologies, methods, and equipment should be considered part of the specification.

[0043] like Figures 1 to 4 As shown, the blind hole processing equipment disclosed in the first embodiment of the present application includes: a grinding head assembly 10, a driving assembly 20 and a shooting assembly 30, the grinding head assembly 10 includes a grinding section 11 and a connecting section 12, the grinding section 11 is connected to the connecting section 12, the end of the grinding section 11 away from the connecting section 12 has a friction contact surface 111 and a groove 112, the groove 112 is arranged through the friction contact surface 111, the driving assembly 20 includes a rotating driving structure 21 and a moving driving structure 22, the rotating driving structure 21 is connected to the connecting section 12, the moving driving structure 22 is connected to the rotating driving structure 21, and the shooting assembly 30 is connected to the moving driving structure 22.

[0044] The technical solution of the first embodiment is applied, the grinding head assembly 10 is installed on the driving assembly 20, the glass is placed under the grinding head assembly 10, the rotation driving structure 21 and the moving driving structure 22 are used to control the movement and rotation of the grinding head assembly 10 respectively, the friction contact surface 111 contacts the glass, the glass is ground, and the blind hole processing is realized. Since a groove 112 is provided that passes through the friction contact surface 111, during the processing, cooling water can pass through the groove 112, thereby increasing the contact area between the grinding section 11 and the cooling water, and the cooling effect is better, and the grinding section 11 is not prone to local overheating. The technical solution of the first embodiment effectively solves the problem in the prior art that the edge of the blind hole is easily damaged during the blind hole processing of the glass.

[0045] It should be noted that the entire grinding head assembly 10 is an integrally formed structure.

[0046] like Figures 1 to 3 As shown, in the technical solution of the first embodiment, the groove 112 includes one groove 112, which is arranged in the middle of the friction contact surface 111 at one end of the grinding section 11 away from the connecting section 12. The groove 112 is processed to the middle of the friction contact surface 111, so that the friction contact surface 111 includes two, the upper end of the grinding section 11 is cylindrical, the first end of the cylindrical section is connected to the connecting section 12, and the second end of the cylindrical section has two protrusions, and the two friction contact surfaces 111 are respectively located at the end of the two protrusions away from the cylindrical section. The two friction contact surfaces 111 are respectively located on both sides of the groove 112, and the entire grinding head assembly 10 is a symmetrical structure to ensure that the glass surface is subjected to a relatively uniform force during the grinding process, avoiding the problem of easy breakage of the glass due to the large local force on the glass. At the same time, the groove 112 is opened in the middle of the friction contact surface 111, which is conducive to the rapid cooling of the entire grinding section 11 and avoids local overheating of the grinding section 11.

[0047] like Figures 1 to 3 As shown, in the technical solution of the first embodiment, the difference between the diameter of the grinding segment 11 and the groove width of the groove 112 is greater than 9 mm and less than 15 mm. In the first embodiment, a grinding head assembly 10 made of tungsten steel is selected and 1000# ceramic powder is sprayed. The diameter of the grinding segment 11 is d, the groove width of the groove 112 is x, and (dx) / 2 is the width of the protrusion. Therefore, when the difference between the diameter of the grinding segment 11 and the width of the groove 112 is less than 9 mm, that is, the width of the raised portion is less than 4.5 mm, during the grinding process, the raised portion is prone to twisting and deformation, resulting in structural failure of the grinding segment 11, the product is easily damaged, and the service life of the grinding head assembly 10 is relatively low; when the difference between the diameter of the grinding segment 11 and the width of the groove 112 is greater than 15 mm, that is, the width of the raised portion is greater than 7.5 mm, the internal cooling effect of the raised portion is poor, resulting in local overheating of the middle area of ​​the corresponding friction contact surface 111, which is likely to cause glass edge chipping and the service life of the grinding segment 11 is reduced.

[0048] like Figures 1 to 3As shown, in the technical solution of the first embodiment, the depth of the groove 112 is less than 0.8 times the difference between the diameter of the grinding segment 11 and the groove width of the groove 112, and greater than 0.5 times the difference between the diameter of the grinding segment 11 and the groove width of the groove 112. The depth of the groove 112 is the height of the protrusion in the vertical direction. When the depth of the groove 112 is greater than 0.8 times the difference between the diameter of the grinding segment 11 and the groove width of the groove 112, that is, the height of the protrusion in the vertical direction is greater than 1.6 times the width of the protrusion, the length of the protrusion in the vertical direction is too large. During the grinding process, the protrusion is easily twisted and deformed under force, resulting in structural failure of the grinding segment 11, the product is easily damaged, and the service life of the grinding head assembly 10 is relatively low; when the depth of the groove 112 is less than 0.5 times the difference between the diameter of the grinding segment 11 and the groove width of the groove 112, that is, the height of the protrusion in the vertical direction is less than 1.0 times the width of the protrusion, the volume of the accommodating space of the groove 112 is small, which is not conducive to the flow of cooling water and the cooling effect is poor, resulting in local overheating of the middle area of ​​the corresponding friction contact surface 111, which is easy to cause glass edge collapse and the service life of the grinding segment 11 is reduced.

[0049] It should be noted that the depth of the above-mentioned groove 112 refers to the case where the bottom of the groove 112 is a plane. When the bottom of the groove 112 is not a plane, such as Figure 1 As shown, the depth specifically refers to the minimum depth of the groove 112 . Figure 1 The setting of the bottom of the middle groove provides a larger accommodating space for cooling water, with better cooling effect, and the lower end strength of the protrusion is higher, and the protrusion is not easy to be twisted. In other embodiments, the bottom of the groove 112 can also be a curved surface, etc., which can also play the role of increasing the cooling water accommodating space.

[0050] like Figure 1 and Figure 2As shown, in the technical solution of the first embodiment, the end of the grinding section 11 away from the connecting section 12 also has an edge groove 113, and the edge groove 113 is located on the circumferential outer side of the friction contact surface 111. The edge groove 113 is designed according to the chamfer shape of the upper edge of the blind hole to be processed, and the angle of the bevel of the edge groove 113 is consistent with the angle of the chamfer. During the processing, it is only necessary to horizontally move the rotating grinding head assembly 10 so that the bevel of the edge groove 113 contacts the upper edge of the blind hole to achieve the chamfering process. If the edge groove is not provided, the vertical outer wall of the grinding section 11 is required to contact the upper edge of the blind hole, and the rotating grinding head assembly 10 is controlled to move in the vertical and horizontal directions to achieve the chamfering process. This processing method is more complex to control and has low precision. Due to the action of external forces in the radial direction and upward of the blind hole, the edge of the blind hole is easily damaged. The corner slot 113 is provided so that during the chamfering process, the blind hole edge is subjected to radial and downward forces, so that the blind hole edge is not easily damaged, and the product quality is better. The connecting section 12 is provided with an anti-misuse groove to distinguish grinding head assemblies 10 of different specifications to avoid misuse during use.

[0051] like Figure 3 and Figure 4 As shown, in the technical solution of the first embodiment, the rotation driving structure 21 includes a motor 211 and a mounting seat 212, the mounting seat 212 is connected to the output end of the motor 211, and the shooting assembly 30 and the grinding head assembly 10 are both mounted on the mounting seat 212. The axis of the output end of the motor 211 and the axis of the grinding head assembly 10 are located on the same straight line, the shooting assembly 30 takes pictures of the blind hole, or monitors in real time, so as to facilitate the quality inspection of the blind hole after processing. The shooting assembly 30 and the grinding head assembly 10 are both arranged on the mounting seat 212, so that the driving assembly 20 can realize the position control of the shooting assembly 30 and the grinding head assembly 10, ensuring that the two can move above the entire glass panel to meet the processing and inspection of each point according to the design requirements.

[0052] like Figure 3As shown, in the technical solution of the first embodiment, the grinding head assembly 10 is arranged at the center of the mounting seat 212, and the shooting assembly 30 includes two. The two shooting assemblies 30 include a slide rail structure 31 and a shooting structure 32. The slide rail structure 31 is connected to the mounting seat 212 and symmetrically arranged on both sides of the grinding head assembly 10. The shooting structure 32 is movably connected to the slide rail structure 31. When the blind hole is circular, the grinding head assembly 10 is adjusted to be located directly above the center of the blind hole by using the mobile driving structure, and the two shooting structures 32 are moved respectively so that the distances between the two and the grinding head assembly 10 are the same, and the irradiation position of the shooting structure 32 is exactly located at the edge of the blind hole. The motor 211 drives the mounting seat 212 to rotate, driving the two shooting structures 32 to move along the edge of the blind hole at the same time. Since there are two shooting structures 32, it only needs to rotate half a circle to achieve the shooting of the entire blind hole edge, and the inspection efficiency is high. Similarly, when the blind hole is in a long strip shape, the two shooting structures 32 can be adjusted to correspond to the two long sides of the blind hole respectively, and the mobile drive structure 22 is used to control the movement of the mounting seat 212 to shoot the two long sides at the same time. The slide rail structure 31 includes a guide rail, which is U-shaped and has baffles at both ends. A screw parallel to the guide rail is arranged in the guide rail, and the two ends of the screw are rotatably connected to the baffle. The shooting structure 32 is partially arranged in the guide rail, and the shell of the shooting structure 32 cooperates with the screw. Under the action of the screw transmission, the rotation of the screw can drive the shooting structure 32 to move along the arrangement direction of the guide rail to achieve the position adjustment of the shooting structure 32. The use of the screw transmission method to adjust the position of the shooting structure 32 avoids the shooting structure 32 being moved away from the rotation axis under the action of centrifugal force during the rotation of the mounting seat 212, causing the shooting structure 32 to be thrown out or collide with other structures.

[0053] like Figure 3 and Figure 4As shown, in the technical solution of the first embodiment, the blind hole processing equipment also includes a cooling component 40, and the cooling component 40 includes a liquid outlet pipeline 41, and the liquid outlet pipeline 41 is fixed on the mounting seat 212, and the liquid outlet direction of the liquid outlet pipeline 41 is set toward the groove 112. The liquid outlet pipeline 41 flows out cooling water to quickly cool the grinding head assembly 10, and the liquid outlet pipeline 41 includes a first pipe section and a second pipe section, and the second pipe section is connected to the first pipe section and is set toward the groove 112. A cooling water receiving chamber is provided on the mounting seat, and the first pipe section is connected to the cooling water receiving chamber, and a solenoid valve is provided on the second pipe section. The second pipe section is inclined, and the diameter of the second pipe section is continuously reduced in the direction from approaching to away from the first pipe section, so as to concentrate the cooling water flow, so that the cooling water flow can directly enter the groove 112, and the cooling effect is better. Compared with the traditional method of rotating the grinding head assembly 10 alone, the cooling assembly 40 is set on the mounting seat 212, so that the liquid outlet pipeline 41 rotates synchronously with the grinding head assembly 10. During the processing, the second pipeline is always set toward the end of the groove 112, which is conducive to the cooling water entering the groove 112 and the cooling efficiency is higher.

[0054] In the technical solution of the first embodiment, the blind hole processing equipment also includes a drying component, and the drying component includes a heating structure and an air outlet structure. The heating structure is arranged inside the workbench of the blind hole processing equipment. The heating structure adopts electric heating to heat the glass arranged on the workbench, which is conducive to the rapid evaporation of cooling water; the air outlet structure includes a first air path and a second air path. The first air path is arranged inside the workbench and is connected to the gas source. When the heating structure heats the workbench and the glass, it can heat the gas in the first air path at the same time. The second air path is connected to the first air path. The second air path extends out of the workbench from the side wall of the workbench, and the outlet of the second air path faces the center direction of the workbench and is arranged parallel to the upper surface of the workbench. When the second air path blows air, the heated gas is blown out, the gas flow speed on the surface of the workbench is accelerated, and the surface temperature of the glass is increased, and the evaporation of cooling water is further accelerated. The second air path includes multiple, and the multiple second air paths are arranged on any side of the workbench, and the air outlet directions are arranged in parallel to avoid the formation of turbulence and affect the drying efficiency. The setting of the drying component avoids the problem that cooling water remains on the glass surface, causing the shooting structure 32 to be affected by refraction when shooting the blind hole, resulting in erroneous quality judgment. When the second air path is exhausted, glass fragments on the glass surface can be blown out, further avoiding the problem that the blind hole is blocked and affects the quality judgment.

[0055] In the technical solution of the first embodiment, the shooting component 30 also includes a light source, which is connected to the shell of the shooting structure 32. In order to avoid a series of problems such as cooling water flying out, the blind hole processing equipment is provided with a shell, and the above structures are all arranged inside the shell. Therefore, it is necessary to set a light source to provide illumination for the shooting structure 32 to avoid poor shooting effects due to lighting environment problems, which affects quality judgment, and the setting of the shell can also avoid the influence of external natural light on the shooting effect.

[0056] like Figure 5 As shown, the difference between the technical solution of the second embodiment and the technical solution of the first embodiment is that the groove 112 includes a plurality of grooves 112, and the plurality of grooves 112 are cross-arranged and centrally symmetrically arranged, and the intersection of the plurality of grooves 112 is located at the center of the friction contact surface 111 of the end of the grinding section 11 away from the connecting section 12. In the second embodiment, the groove 112 includes two grooves 112, and the two grooves 112 are perpendicular to each other, and are arranged on the end surface of the grinding section 11 to divide the friction contact surface 111 into four centrally symmetrical surfaces. While ensuring the cooling effect, it is ensured that the force on the glass surface is uniform during the grinding process, and the glass is not easily broken. In other embodiments, the grooves 112 can also include three, four, etc., but in order to ensure that the protrusion is not easily deformed, the number of grooves 112 is preferably one or two.

[0057] According to another aspect of the present application, a blind hole quality inspection method is also provided. The blind hole quality inspection method adopts the above-mentioned blind hole processing equipment, and the blind hole quality inspection method comprises the following steps:

[0058] The mobile driving structure 22 drives the grinding head assembly 10 to move above the blind hole to be processed;

[0059] The rotation driving structure 21 drives the grinding head assembly 10 to rotate, and the moving driving structure 22 drives the grinding head assembly 10 to move vertically downward, so that the friction contact surface 111 contacts the glass and processes the blind hole according to the required size;

[0060] After the driving component 20 drives the grinding head component 10 away from the blind hole, the photographing component 30 photographs the blind hole to obtain an image;

[0061] Determine whether the appearance quality of the blind hole is qualified based on the image.

[0062] The grinding head assembly 10 in the first embodiment and the device without the groove 112 are used and the above steps are adopted to process the blind holes respectively, and the diameter of the grinding head is 16.2 mm. The width of the groove 112 of the grinding head assembly 10 of the present application is 7.15 mm. Three groups of different feed speeds are selected, the first group is 0.1 m / min, the second group is 0.2 m / min, and the third group is 0.3 m / min. Each speed corresponds to processing ten blind holes of the same size. Three are selected for inspection, and the blind holes are photographed by the shooting assembly 30 to observe the edge collapse of the blind holes, as shown in Tables 1 and Figures 6 to 11 The experimental group is a grinding head assembly with a groove 112, and the control group is a grinding head assembly without a groove 112. Table 1 shows the edge collapse of the blind hole in the two groups of experiments.

[0063] Table 1

[0064]

[0065] Combining Table 1 and Figures 6 to 11 It can be seen that the grinding head assembly 10 with the groove 112 is less likely to have edge collapse during the blind hole processing, and the damaged area is smaller, and the blind hole quality is higher.

[0066] In addition to visual observation, you can also use a computer to process the images.

[0067] First, a product defect library is established. According to the quality standards, qualified product images and unqualified product images are distinguished. Through continuous verification, a standard product defect library is obtained. The captured images are uploaded to a computer or other processing equipment to preprocess the images, including: Grayscale: Convert color images to grayscale images to simplify the processing process. Filter denoising: Use median filtering, Gaussian filtering and other methods to remove noise in the image and improve image quality. Enhance contrast: Enhance the contrast of the image through methods such as histogram equalization to make the outlines of crystallization and stones clearer. Feature extraction is performed on the processed image, including: Texture features: Use gray level co-occurrence matrix (GLCM), local binary pattern (LBP) and other methods to extract image texture features. These features are very helpful for identifying crystallization and stones in glass. Shape features: Extract shape features of stones or crystallization areas, such as aspect ratio, circularity, area, etc., to distinguish different types of defects. Grayscale features: Analyze the grayscale distribution of stones or crystallization areas, such as grayscale mean, variance, etc., to further distinguish them from normal glass areas. The processed image is segmented, including: Threshold segmentation: Set a threshold according to the gray value or texture feature of the image to segment the image into stone / crystallization area and normal glass area. Edge detection: Use edge detection algorithms such as Canny and Sobel to extract the edge contour of the stone / crystallization area. Region growing: Starting from the known stone / crystallization seed point, region growing is performed according to the similarity between pixels (such as grayscale, texture, etc.) to segment the complete stone / crystallization area. Post-processing and recognition are performed, including: Morphological processing: Use morphological operations such as corrosion, expansion, opening operation, closing operation, etc. to further process the segmented stone / crystallization area to remove noise and refine the contour. Classification and recognition: Input the extracted features into a classifier (such as a support vector machine, a neural network, etc.) for training and learning to achieve automatic recognition of stones / crystallization. The above computer processing method is suitable for large-scale blind hole quality inspection, and the inspection efficiency is higher.

[0068] From the above, it can be seen that the design method of the present application is as follows: a drainage groove (groove 112) is designed at the bottom of the grinding head (grinding head assembly 10) to improve the bottom friction, ensure the contact of circulating water, and increase the life of the grinding head; reduce the processing contact surface to avoid the collapse and breakage of glass sand due to sand falling; add an edge groove 113 on the outside of the grinding head to effectively achieve the effect of clear edges and corners of the blind hole; design an anti-fool groove (anti-fool groove 121) to effectively prevent the grinding head from being used incorrectly and avoid processing abnormalities.
