Description

Technical Field

[0001] The utility model provides a detection device, belonging to the technical field of glass panel detection equipment, and particularly relates to a glass panel surface defect detection device. Background Art

[0002] The detection of glass panel surface defects refers to the use of technologies such as optics, image processing, and machine learning to carefully inspect the surface of the glass panel to identify and classify various defects, such as scratches, bubbles, impurities, cracks, etc. The role of this technology is to ensure the quality of glass products, improve production efficiency, reduce costs, and meet the strict requirements for the surface quality of glass in different application fields. Through an automated detection system, problems can be quickly and accurately discovered, so that adjustments can be made in a timely manner during the production process or unqualified products can be eliminated in the quality control link, ensuring the reliability and aesthetics of the final product.

[0003] In the visual inspection of glass panels, a light source with a specific wavelength is usually used for illumination to enhance the visualization of defect features. Due to its shorter wavelength, blue light provides higher spatial resolution and is particularly suitable for detecting minute surface defects, such as micron-sized scratches and impurities. Relatively speaking, red light has a longer wavelength and stronger scattering ability, and can penetrate the surface more effectively, and is suitable for detecting surface defects of glass panels, such as cracks and bubbles. However, since surface defects such as scratches may be distributed in any direction, illumination with a light source at a single angle may not fully reveal these defects, resulting in incomplete detection results. Therefore, in order to improve the detection accuracy, a multi-angle illumination strategy may be required to ensure sufficient illumination and imaging of defects from different directions. Summary of the Utility Model

[0004] In order to make up for the deficiencies of the prior art, the embodiments of the present application provide a glass panel surface defect detection device, which solves the problem that the existing equipment cannot perform multi-angle light source illumination, affecting the comprehensive detection of surface and subsurface defects.

[0005] In order to solve the above technical problems, the utility model provides the following technical solution: A glass panel surface defect detection device includes a placement table, and an adjustment structure is arranged inside the upper part of the placement table. The adjustment structure includes an adjustment ring inserted into the placement table. A sliding groove penetrating through itself is arranged on the part of the adjustment ring above the placement table, and a vision device and a lighting device corresponding to and staggered with itself are arranged inside the sliding groove.

[0006] Preferably: Rollers evenly distributed on both sides of the adjustment structure are arranged on the placement table, and a conveying roller penetrating through itself and parallel to the rollers is arranged inside the adjustment ring.

[0007] Preferably, a through groove penetrating the sliding groove in the horizontal direction is provided inside the sliding groove, and evenly distributed gear grooves are provided on the part of the adjusting ring away from the through groove.

[0008] Preferably, both the visual device and the lighting device include cross-shaped sliding blocks corresponding to the sliding groove and the through groove, and a locking bolt structure penetrating the sliding block is provided inside the sliding block.

[0010] One or more technical solutions provided in the embodiments of the present application have at least the following technical effects or advantages:

[0011] By providing an adjusting structure placed inside the placing table, the present utility model drives the position transformation of the visual device and the lighting device by means of the position conversion of the adjusting ring in the placing table, thereby changing the irradiation and shooting angles. At the same time, the visual device and the lighting device can slide freely in the sliding groove, so as to facilitate the selection of more angles and a larger angle range.

[0024] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by those skilled in the technical field to which the present invention belongs; the terms used in the specification of the present invention herein are only for the purpose of describing specific implementation manners and are not intended to limit the present invention; the term "and / or" used herein includes any and all combinations of one or more of the related listed items.

[0025] As Figure 1 and Figure 2 As shown, a glass panel surface defect detection device includes a placement table 1, an adjustment structure 2 located inside the placement table 1 above, and roller shafts 11 located on the placement table 1 and on both sides of the adjustment structure 2. A transfer roller 12 that penetrates itself and is parallel to the roller shaft 11 is provided inside the adjusting ring 21. The adjusting structure 2 includes an adjusting ring 21 inserted into the placement table 1. A sliding groove 22 that penetrates itself is provided on the part of the adjusting ring 21 above the placement table 1. A visual device 23 and a lighting device 24 that correspond to itself and are staggeredly distributed are provided inside the sliding groove 22.

[0026] In this implementation scheme, through the precision adjustment mechanism 2 built in the carrier table 1, the axial displacement of the adjusting ring 21 in the carrier table 1 is utilized to drive the visual device 23 and the lighting device 24 to perform corresponding position adjustments to achieve dynamic optimization of the irradiation and imaging angles. In addition, the visual device 23 and the lighting device 24 are assembled in the guide rail groove 22, allowing them to slide freely along the guide rail, thereby providing a wider range of irradiation and shooting angle selections to adapt to diverse detection requirements and improve the comprehensiveness of defect detection.

[0027] As Figure 3 andFigure 4 As shown, a through groove 25 running horizontally through itself is provided inside the sliding groove 22. Uniformly distributed gear grooves 26 are provided on the part of the adjusting ring 21 away from the through groove 25. Both the vision device 23 and the lighting device 24 include cruciform sliding blocks 27 corresponding to the sliding groove 22 and the through groove 25. A locking bolt structure 28 running through itself is provided inside the sliding block 27. A transmission gear 13 corresponding to itself is provided below the gear groove 26. The transmission gear 13 is connected by a rotating shaft to a clamping member 14 sleeved outside the adjusting ring 21. A driving device corresponding to itself and placed inside the placement table 1 is provided below the transmission gear 13.

[0028] In this implementation scheme, the driving mechanism includes two independent motor systems: the first motor is responsible for driving the transmission gear 13 to realize the rotation of the adjusting ring 21; the second motor is used to drive the clamping member 14 to drive the adjusting ring 21 to rotate around the axis of the clamping member 14. The first motor adjusts the horizontal positions of the vision detection device 23 and the lighting device 24 by precisely controlling the rotation of the adjusting ring 21 to adapt to glass panels of different sizes. The second motor realizes the swing of the adjusting ring 21 within a certain angle range of the placement table by driving the rotation of the adjusting ring 21 relative to the clamping member 14, thereby expanding the irradiation angle change range of the vision detection device 23 and the lighting device 24 to realize the omnidirectional detection of the surface defects of the glass panel.

[0029] During use, place the glass panel on the storage table (1), ensuring that the glass panel is placed stably and horizontally for subsequent inspection. Start the precision adjustment mechanism (2) built into the storage table (1). This mechanism includes two motor systems for driving the position change of the adjustment ring (21). Drive the transmission gear (13) through the first motor to rotate the adjustment ring (21) axially around the storage table (1), thereby adjusting the lateral positions of the vision device (23) and the lighting device (24) to adapt to the size of the glass panel and the inspection area. Start the second motor to drive the clamping part (14) to rotate the adjustment ring (21) around the axis of the clamping part (14), realizing the swing of the adjustment ring (21) within a certain angle range above the storage table (1), thereby adjusting the irradiation angles of the vision device (23) and the lighting device (24). The vision device (23) and the lighting device (24) are assembled in the sliding groove (22). Through manual or automatic control, the module can slide freely along the sliding groove (22) to obtain irradiation and shooting at more angles. The horizontal through groove (25) and the gear groove (26) inside the sliding groove (22) work together. Through the sliding block (27) and the locking bolt structure (28), the positions of the vision device (23) and the lighting device (24) are precisely controlled. After adjusting the positions and angles of the vision device (23) and the lighting device (24), start the inspection program to perform surface defect inspection on the glass panel. During the inspection process, the image data captured by the vision device (23) is transmitted to the data processing system for defect identification and analysis. According to the inspection results, the system will automatically record the position, type, and size of the defects and generate an inspection report. After the inspection is completed, reset the adjustment mechanism to prepare for the next inspection or shut down the system.
