Description

Technical Field

[0001] This application relates to the field of glass testing technology, and in particular to a glass testing bracket and a glass testing system. Background Technology

[0002] Optical distortion is a crucial technical indicator in float glass quality testing. It refers to the degree of distortion of objects seen through the glass when viewed by a person, caused by surface irregularities or uneven refractive index within the glass. During float glass production, factors such as poor molten glass quality, uneven molten glass composition, large nodules, streaks, ripples, strings of bubbles, stones, or improper forming parameters can all lead to substandard optical properties in float glass.

[0003] The zebra stripe method is used to evaluate the optical deformation properties of float glass. This is usually done by sampling the cut glass offline and using a manual zebra stripe for visual inspection or a zebra stripe meter to test and evaluate the optical properties of the sample.

[0004] Glass samples can usually only be placed horizontally on a shelf and then placed in an optical darkroom for testing, which cannot simulate the tilting conditions that may occur during actual installation and use of glass. Utility Model Content

[0005] This application proposes a glass inspection bracket and a glass inspection system, which aims to provide a way to simulate the working conditions of automotive glass in actual use and perform optical inspection on it, avoiding the problem of missed defects that may occur during horizontal single-angle inspection.

[0006] One embodiment of this application provides a glass testing bracket, comprising: The frame has a first shelf surface; A support plate is rotatably mounted on the frame, and the support plate has a second placement surface; An adjustment component is provided at the connection between the frame and the support plate to adjust the angle between the second placement surface and the first placement surface.

[0011] In one embodiment, the frame includes a first frame, a second frame, and a column disposed between the first frame and the second frame, wherein the first shelf is disposed on the side of the first frame facing away from the column.

[0012] In one embodiment, the column includes a first telescopic section, a second telescopic section, and a third telescopic section, wherein the first telescopic section is slidably disposed on the second telescopic section, and the second telescopic section is disposed on the third telescopic section; The first telescopic segment has a first engaging protrusion in its circumferential direction, which is used to engage and limit the second telescopic segment; the second telescopic segment has a second engaging protrusion in its circumferential direction, which is used to engage and limit the third telescopic segment.

[0013] In one embodiment, the glass inspection bracket further includes casters, which are located on the side of the second frame facing away from the column.

[0014] One embodiment of this application also proposes a glass inspection system, comprising: The cover has a detection space, and the side wall of the cover is provided with a first stripe light source facing the detection space; The glass testing bracket described above is located within the testing space.

[0015] In one embodiment, a second stripe light source is provided on the top of the cover, and the angle of the second stripe light source is adjustable.

[0016] This application utilizes a support plate rotatably mounted on a frame. A glass sample to be inspected can be placed on the support plate, allowing for adjustment of the support plate to tilt the glass at any angle for more comprehensive optical inspection. Specifically, the glass inspection bracket includes a frame, a support plate, and an adjusting mechanism. The frame has a first placement surface, and the support plate has a second placement surface. Both surfaces are used to place the glass sample to be inspected. The first placement surface is a horizontal inspection surface, and the second placement surface is an inclined inspection surface. The glass sample can be placed on the first placement surface for horizontal visual inspection and on the second placement surface for inclined visual inspection. By adjusting the adjusting mechanism, the angle between the support plate and the frame can be further adjusted to accommodate different glass products.

[0017] By adding a tilting placement function, it can simulate the tilting conditions that may occur during actual glass installation and use, more closely matching real application scenarios to detect optical deformation at different tilt angles. It can also comprehensively capture the performance of directional defects such as ripples and lines under different light refraction angles through multi-angle testing, avoiding the defect omission problem that may occur in horizontal single-angle testing.

[0024] Optical distortion is a crucial technical indicator in float glass quality testing. It refers to the degree of distortion of objects seen through the glass when viewed by a person, caused by surface irregularities or uneven refractive index within the glass. During float glass production, factors such as poor molten glass quality, uneven molten glass composition, large nodules, streaks, ripples, strings of bubbles, stones, or improper forming parameters can all lead to substandard optical properties in float glass.

[0025] The zebra stripe method is used to evaluate the optical deformation properties of float glass. This typically involves sampling and offline testing of the cut glass, using a manual zebra stripe for visual inspection or a zebra stripe meter to assess the optical performance of the sample. However, glass samples are usually placed horizontally on a shelf and then placed in an optical darkroom for testing, which cannot simulate the tilting conditions that may occur during actual installation and use of the glass.

[0026] To address the aforementioned problems, this application proposes a glass testing bracket 100 to solve the technical issues raised above.

[0027] Please see Figure 1 In one embodiment of this application, the glass testing bracket 100 includes a frame 1, a support plate 2, and an adjusting member 3. The frame 1 has a first placement surface, the support plate 2 is rotatably disposed on the frame 1, the support plate 2 has a second placement surface, and the adjusting member 3 is disposed at the connection between the frame 1 and the support plate 2 to adjust the angle between the second placement surface and the first placement surface.

[0028] This application provides a support plate 2 mounted on a frame 1, allowing the support plate 2 to be rotatably mounted on the frame 1. A glass sample to be inspected can be placed on the support plate 2, and the support plate 2 can be adjusted to tilt the glass to any angle for more comprehensive optical inspection. Specifically, the glass inspection bracket 100 includes a frame 1, a support plate 2, and an adjusting member 3. The frame 1 has a first placement surface, and the support plate 2 has a second placement surface. Both the first and second placement surfaces are used to place the glass sample to be inspected. The first placement surface is a horizontal inspection surface, and the second placement surface is an inclined inspection surface. The glass sample can be placed on the first placement surface for horizontal visual inspection and on the second placement surface for inclined visual inspection. By adjusting the adjusting member 3, the operator can further adjust the angle between the support plate 2 and the frame 1, thus adapting to different glass products.

[0029] By adding a tilting placement function, it can simulate the tilting conditions that may occur during actual glass installation and use, more closely matching real application scenarios to detect optical deformation at different tilt angles. It can also comprehensively capture the performance of directional defects such as ripples and lines under different light refraction angles through multi-angle testing, avoiding the defect omission problem that may occur in horizontal single-angle testing. At the same time, it can obtain test data at different angles to form more complete performance parameters, providing a more comprehensive reference for glass quality assessment and production process optimization. It can also improve the adaptability of the testing device to different testing needs, and enhance the flexibility and practicality of testing.

[0030] To achieve a rotatable connection between the frame 1 and the support plate 2, the frame 1 has at least one first hinge portion 111 near the support plate 2, and the support plate 2 has at least one second hinge portion 21 near the frame 1. The first hinge portion 111 and the second hinge portion 21 are hinged together. This hinged connection allows for stable rotation of the support plate 2 relative to the frame 1, providing a reliable structural basis for adjusting the angle between the second and first placement surfaces. This ensures that the support plate 2 can accurately remain at the required tilt angle during glass testing, preventing angle deviation due to loose connections and guaranteeing testing accuracy. Furthermore, the hinged structure distributes stress evenly, dispersing the pressure generated when the glass sample is placed on the support plate 2, reducing localized wear at the connection between the frame 1 and the support plate 2, and extending the service life of the entire glass testing bracket 100. Compared to other detachable or fixed connection methods, hinged connections do not require frequent disassembly of components, making operation convenient. Staff can quickly adjust the tilt angle of the support plate 2, improving the efficiency of glass inspection and facilitating subsequent maintenance and repair of the bracket.

[0031] Please see Figure 2In some embodiments of this application, the adjusting member 3 includes a stud 31 and a nut 32. The stud 31 passes through the first hinge portion 111 and the second hinge portion 21. One end of the stud 31 is provided with an end head 311. One of the end head 311 and the nut 32 abuts against the first hinge portion 111, and the other abuts against the second hinge portion 21. During adjustment, the nut 32 is loosened first to reduce the clamping force between the end head 311 and the first hinge portion 111, and between the nut 32 and the second hinge portion 21. At this time, the first hinge portion 111 and the second hinge portion 21 can rotate relative to each other around the through stud 31. The operator only needs to push the support plate 2 to drive the second hinge portion 21 to rotate synchronously with the support plate 2 until the support plate 2 is adjusted to the required angle. After the angle is determined, tighten the nut 32 in the opposite direction to move the nut 32 toward the end 311, gradually increasing the clamping pressure of the end 311 against the first hinge 111 and the nut 32 against the second hinge 21. When the pressure is large enough, the relative rotation between the first hinge 111 and the second hinge 21 is restricted, and the angle of the support plate 2 is locked and can be stably maintained in the adjusted position.

[0032] Furthermore, in an optional embodiment, the frame 1 includes two first hinge portions 111, which are spaced apart; the support plate 2 includes two second hinge portions 21, which are spaced apart. The first hinge portions 111 and the second hinge portions 21 are alternately arranged along the length of the stud 31. By providing two hinge portions, the force on the hinge structure can be more evenly distributed. Compared with a single hinge portion, the two alternately distributed hinge portions can disperse the pressure generated by the support plate 2 and the load above it to the two contact points of the stud 31, avoiding excessive local stress that could cause deformation or wear of the hinge parts, and significantly improving the structural load-bearing capacity and service life. Moreover, the two sets of hinge portions can greatly improve the stability of the support plate 2 after angle adjustment. The alternately arranged double hinge portions can form a bidirectional limit on the support plate 2 from both sides, reducing the possibility of the support plate 2 shifting left or right or shifting angle due to external forces after adjustment, ensuring that the support plate 2 always remains stably at the set angle, which is especially suitable for scenarios with high requirements for support stability, such as glass inspection. The symmetrical double-hinged structure also allows the stud 31 to be subjected to more balanced force when it passes through, preventing the stud 31 from bending due to uneven force on one side, further ensuring the reliability of the entire adjustment and locking mechanism. At the same time, it makes it easier for operators to control the rotation direction of the support plate 2 when adjusting the angle, improving the ease of operation.

[0033] Please see Figure 1To prevent the glass from slipping off the frame 1 or the support plate 2, the first shelf surface of the frame 1 is provided with multiple anti-slip pads 4, and the second shelf surface of the support plate 2 is also provided with multiple anti-slip pads 4. It should be noted that the anti-slip pads 4 can be made of silicone, rubber, or other materials with a high coefficient of friction. This application does not limit the scope of this application. In one embodiment, the anti-slip pad 4 is made of silicone. Silicone itself has high friction and can generate sufficient static friction through close contact between the pad and the glass surface. This effectively counteracts the tendency of the glass to slide due to the placement angle (especially when the second placement surface is tilted) or slight vibration, fundamentally preventing the glass from slipping and avoiding glass breakage or interruption of the testing process. Secondly, silicone is soft and has a certain degree of elasticity. When in contact with the glass, it can form a buffer. Unlike hard materials, it will not scratch the glass surface and affect the testing accuracy. It can also adapt to the slight unevenness of the glass surface, further improving the contact stability. Furthermore, the distribution design of multiple pads can make the glass more evenly stressed, avoiding local pressure breakage caused by single-point stress. At the same time, it can also adapt to the placement requirements of different sized glass by the spacing of the pads, ensuring that all types of glass can be stably positioned during the testing process, providing a reliable guarantee for the accuracy and safety of glass testing.

[0034] Please see Figure 3 The glass inspection bracket 100 proposed in this application is height-adjustable. Specifically, the bracket body 1 includes a first frame 11, a second frame 12, and a column 13 disposed between the first frame 11 and the second frame 12. The first placement surface is disposed on the side of the first frame 11 facing away from the column 13. The column 13 includes a first telescopic section 131, a second telescopic section 132, and a third telescopic section 133. The first telescopic section 131 is slidably disposed on the second telescopic section 132, and the second telescopic section 132 is disposed on the third telescopic section 133. The first telescopic section 131 is provided with a first engaging protrusion 1311 in the circumferential direction, which is used to engage and limit the second telescopic section 132. The second telescopic section 132 is provided with a second engaging protrusion 1321 in the circumferential direction, which is used to engage and limit the third telescopic section 133.

[0035] The lifting and lowering of the column 13 in this scheme is achieved through a three-section telescopic structure and a pressable pop-out locking protrusion. The specific process is as follows: During adjustment, press the first locking protrusion 1311 around the first telescopic section 131 inward to disengage it from the locking limit of the second telescopic section 132. At this time, the first telescopic section 131 can slide up and down along the inner wall of the second telescopic section 132 until the first frame 11 reaches the required height. After releasing the press, the first locking protrusion 1311 pops out and re-engages with the second telescopic section 132, completing the first stage of height fixation. If further adjustment of the overall height is required, press the second locking protrusion 1321 around the second telescopic section 132 inward to release it from the locking with the third telescopic section 133. Push the second telescopic section 132 along the third telescopic section 133 to the target height. After releasing, the second locking protrusion 1321 pops out and locks in place, realizing the overall height adjustment. By adding a height adjustment function, firstly, it can flexibly adapt to the testing needs of different glass sizes. Whether it's large glass requiring a higher support height for ease of operation, or small glass requiring a lower height for stability, precise adaptation can be achieved by adjusting the height of the column 13. Secondly, it adapts to the operating habits of staff of different heights, avoiding the need for staff to bend over or stand on tiptoe due to a fixed support height, thus improving comfort and ease of operation during the testing process. Thirdly, combined with the anti-slip pads 4 on the first and second placement surfaces, the height adjustment allows the glass to be placed stably at different heights, preventing slippage and allowing for flexible adjustment of the glass placement height according to the testing steps, providing support for efficient glass testing.

[0036] Please continue reading. Figure 1 In one embodiment, the glass inspection bracket 100 also includes casters 5, which are located on the side of the second frame 12 facing away from the column 13. The casters 5 greatly improve the ease of movement of the bracket. Compared to a fixed base, the casters 5 can easily move the bracket within the inspection area without requiring staff to carry or lift it laboriously. This is especially beneficial for large-sized glass or heavy brackets, significantly saving manpower and reducing the risk of glass breakage during transport. Secondly, it provides the bracket with more flexible position adjustment capabilities. If the glass placement needs to be adjusted to fit the inspection equipment, or if the bracket needs to be moved to different inspection areas, the casters 5 can rotate 360°, allowing for more precise and efficient fine-tuning without repeatedly moving the entire bracket. Furthermore, the casters 5 have a built-in braking function. After moving to the target position, the wheels can be locked by braking to keep the bracket stable. This balances ease of movement with ensuring that the glass will not be affected by accidental slippage during inspection, thus preventing it from falling and ensuring the safety and stability of the glass inspection process.

[0037] Please see Figure 4This application also proposes a glass inspection system, which includes a cover 200 and a glass inspection bracket 100 as described above. The cover 200 has an inspection space 200a, and a first stripe light source 210 is provided on the side wall of the cover 200 facing the inspection space 200a. The glass inspection bracket 100 is located in the inspection space 200a. The specific structure of the glass inspection bracket 100 is as described in the above embodiments. Since this glass inspection system adopts all the technical solutions of all the above embodiments, it has at least all the beneficial effects brought about by the technical solutions of the above embodiments, which will not be described in detail here.

[0038] When performing optical inspection of glass within the enclosure 200, which serves as an optical darkroom, the glass to be inspected is first placed on the glass inspection bracket 100 located within the inspection space 200a. The glass can be positioned appropriately for inspection by adjusting the bracket height and the angle of the support plate 2, while anti-slip pads 4 are used to secure the glass and prevent it from slipping. The enclosure 200 is then closed to isolate external stray light interference, creating a pure darkroom inspection environment. At this time, the first stripe light source 210, positioned on the side wall of the enclosure 200 facing the inspection space 200a, is activated. The stripe light emitted by this source evenly illuminates the glass surface, and the operator can observe the changes in light passing through the glass through the observation window provided in the enclosure 200. If the glass has defects such as scratches, bubbles, or impurities, these defects will cause the stripe light to refract, scatter, or break. These abnormal light and shadows will be clearly visible against the darkroom background, allowing for accurate identification of glass defects. Simultaneously, the darkroom environment prevents external light from interfering with the stripe light source, ensuring stable light intensity and distribution, leading to more accurate defect identification. The stable support of the glass inspection bracket 100 prevents glass displacement during inspection, further ensuring the reliability of the inspection results.

[0039] An adjustable second stripe light source 220 is installed at the top of the cover 200, which can specifically meet the inspection needs of special glass and bring key advantages: for thick glass, irregularly shaped glass or special glass that needs to be inspected for complex surface and internal defects, the top light source can form three-dimensional illumination with the first stripe light source 210 on the side wall. By adjusting the angle of the top light source, light can be directed obliquely onto the surface of the glass from above, accurately capturing top edge scratches and surface micro-cracks that are difficult to cover by side wall light sources. Adjusting the illumination angle also alters the path of light penetration through the glass, creating a more pronounced light and shadow contrast for bubbles and impurities deep within the glass in the darkroom, preventing missed defects due to blind spots caused by a single side wall light source. Furthermore, the adjustable angle design accommodates special glass of varying thicknesses and placement orientations. For example, when inspecting glass placed at a large angle, adjusting the top light source angle ensures that the light effectively illuminates the inspection area without frequent adjustments to the glass or support position. In addition, the dual-striped light source enhances the layering of light in the darkroom, making defects on the surface of special glass more clearly visible under different angles of light, further improving inspection accuracy and solving the problem of incomplete inspection of special glass by a single light source.
