A limiting rod 27 is fixed inside the placement groove 221; the limiting rod 27 is slidably connected to the limiting groove 241.

[0033] In order to realize the automatic upper and lowering of the glass substrate 4 to be processed, the bottom end of the glass bearing assembly 2 is connected to the base 1, and the top end of the base 1 is provided with a conveying assembly 3; the conveying assembly 3 includes a conveying shaft 31, a conveying belt 32 and a conveying motor 33, and the conveying belt 32 is provided with two groups, and each group of the conveying belts 32 is connected by two conveying shafts 31; one of the conveying shafts 31 is connected to the conveying motor 33, and the glass bearing assembly 2 is arranged between the two conveying belts 32; Figure 5 shown.

[0034] When in use, the glass substrate 4 to be measured and corrected is placed on the surface of the conveyor belt 32, and the conveyor motor 33 is started. When the conveyor motor 33 is started, the conveyor belt 32 and the glass substrate 4 are driven to move. When the conveyor motor 33 reaches the top of the suction cup 26, the electric telescopic rod 21 is started, and the upper glass substrate 4 is sucked by the rising suction cup 26, and then the moving motor 28 is started. When the moving motor 28 is started, the gear 29 is driven to rotate, and then the sliding plate 24 is driven to move to the left by meshing with the plate teeth 242, and move to the edge of the glass substrate 4 to be detected and extend between the first detection component 5 and the second detection component 6 for subsequent detection.

The first detection component 5 and the second detection component 6 can be performed by the same detection device; illustratively, the first detection component 5 is performed by one of the following devices:

[0037] 1. Polarized light imaging device: Use polarized light to illuminate the surface of the glass substrate. The polished glass surface and the unpolished surface have different reflection characteristics for polarized light. These differences can be captured by a polarized camera or polarizing film to distinguish the polishing status.

[0038] 2. Laser scanning imaging device: Using laser as the light source, the laser beam is focused on the surface of the glass substrate. According to the changes in laser reflection or scattering, the microscopic structural changes on the surface, including polishing marks, can be detected.

[0039] 3. Confocal microscope imaging device: Confocal microscope can provide high-resolution three-dimensional images. By adjusting the focus depth, the polishing details of the glass surface can be clearly seen, which is suitable for fine surface structure analysis.

[0040] 4. White light interferometer: Utilizing the interference effect of white light, when white light is irradiated onto the glass surface, different interference patterns will be generated depending on the surface flatness and polishing conditions. By analyzing these patterns, the polishing status of the glass can be determined.

[0041] 5. Structured light imaging device: projects specific gratings or stripes onto the glass surface, and then uses a camera to capture the deformation of these patterns on the surface. By analyzing the degree of deformation through an algorithm, the smoothness and polishing effect of the surface can be determined.

[0042] 6. Phase delay imaging device: This method uses the change in phase difference to detect tiny differences in the glass surface. There will be slight differences in the phase delay of light between polished glass and unpolished glass. These differences can be captured and analyzed through precise optical instruments.

[0043] An image of the edge of the glass substrate is obtained by any of the above methods, and the image processing module is used to perform image processing, the width of the edge grinding surface of the upper and lower glass substrates is calculated, and the deviation of the width of the edge grinding surface of the upper and lower glass substrates is obtained; a correction component 7 is provided on the side of the glass supporting component 2, and the correction component 7 corrects the edge of the glass substrate 4 by grinding according to the calculated edge shape deviation.

[0044] Specifically, a bracket 11 is fixed to the side of the base 1 , and two cross bars 12 are fixed to the side of the bracket 11 , wherein one of the cross bars 12 is connected to the first detection component 5 ; and the side of the other cross bar 12 is connected to the second detection component 6 .

[0045] The sides of the two cross bars 12 are connected to the correction components 7, and the two correction components 7 are symmetrically distributed; the correction components 7 include a pneumatic slide rail 71, a pneumatic slider 72, an electric telescopic rod 73, a grinding motor 74 and a grinding disc 75; Figure 4 As shown, a pneumatic slide rail 71 is fixed to the side of the crossbar 12, and the side of the pneumatic slide rail 71 is slidably connected to a pneumatic slider 72; an electric telescopic rod 73 is provided on the side of the pneumatic slider 72, and the output end of the electric telescopic rod 73 is connected to a grinding motor 74; the output end of the grinding motor 74 is connected to a grinding disc 75. When grinding, according to the test results, it is determined which side of the glass needs to be polished, such as Figure 6 As shown in A in the figure, the difference in shape between the upper and lower surfaces of the glass substrate 4 is that the upper surface grinding surface is wide and the lower surface grinding surface is narrow, then the edge of the lower surface needs to be polished. During polishing, the correction component at the bottom is started, and the position of the polishing disc 75 is adjusted by using the pneumatic slider 72 and the electric telescopic rod 73. After reaching the appropriate position, the polishing motor 74 is used to rotate the polishing disc 75 for polishing, and the movement of the pneumatic slider 72 can be coordinated to perform comprehensive polishing of the edge; if the detection is as follows Figure 6 As shown in B in FIG. 4 , it means that the widths of the polished surfaces of the upper and lower glass substrate edges of the glass substrate 4 are the same, and the glass substrate 4 is qualified.

[0046] When the present invention is in use, the glass substrate 4 to be measured and corrected is placed on the surface of the conveyor belt 32, and the conveyor motor 33 is started. When the conveyor motor 33 is started, the conveyor belt 32 and the glass substrate 4 are driven to move. When the conveyor motor 33 reaches the top of the suction cup 26, the electric telescopic rod 21 is started, and the upper glass substrate 4 is sucked by the rising suction cup 26, and then the moving motor 28 is started. When the moving motor 28 is started, the gear 29 is driven to rotate, and then the sliding plate 24 is driven to move to the left by meshing with the plate teeth 242, and the edge of the glass substrate 4 to be detected is extended between the first detection component 5 and the second detection component 6. The first detection component 5 and the second detection component 6 successively acquire images of the two end surfaces of the glass substrate 4. For example, a polarized light imaging device is used for detection in a dark room. Since the polarization degree of the reflected light is low, the image More dark areas or spots will appear; while the polarization degree of the light reflected from the smooth surface is higher, the brightness in the image is uniform, and there is almost no dark area, so that the images of the grinding area and the smooth area of ​​the end face of the glass substrate 4 are obtained, and the width of the grinding surface is obtained through the image processing module, and the width of the grinding surface of the edge of the upper and lower glass substrates 4 is calculated, and the image is analyzed to calculate the edge morphology deviation of the upper and lower surfaces; then the unqualified glass substrate 4 is corrected by controlling the correction component 7, and the position of the grinding disc 75 is adjusted by the pneumatic slider 72 and the electric telescopic rod 73 during correction. After reaching the appropriate position, the grinding motor 74 is used to rotate the grinding disc 75 for grinding, and the movement of the pneumatic slider 72 can be coordinated to perform comprehensive grinding of the edge; during grinding, a pressing component can be set to press the glass substrate 4 to prevent the glass substrate 4 from moving during grinding.

[0047] The present invention also provides a method for online measurement and correction of the edge morphology of a glass substrate, comprising:

[0048] S1, making the glass substrate 4 reach the top of the glass supporting assembly 2, and making the side of the glass substrate 4 to be inspected extend between the first inspection assembly 5 and the second inspection assembly 6;

[0049] S2, the edge image of the glass substrate 4 is detected by the first detection component 5 and the second detection component 6, and the image processing module analyzes the image to calculate the edge morphology deviation;

[0050] S3, the calculated deviation value is transmitted to the correction component 7 through the human-computer interaction module to correct the edge of the glass substrate 4. The correction component 7 corrects the edge of the glass substrate 4, including:

[0051] The pneumatic slider 72 is moved on the pneumatic slide rail 71, and the electric telescopic rod 2 73 is telescopically adjusted to adjust the grinding disc 75 to the position that needs to be corrected;

[0052] Start the grinding motor 74 to use the rotating grinding disc 75 to grind and correct;

[0053] After the correction is completed, the first detection component 5 and the second detection component 6 are used again to detect and verify whether the correction is qualified; if qualified, the glass supporting component 2 is used to drive the glass substrate 4 to rotate to detect the other edge; if unqualified, continue to use the correction component 7 to correct.
