Abstract
Description
Technical Field
[0001] This utility model relates to the field of glass gloss testing technology, specifically a glass gloss testing fixture. Background Technology
[0002] In the fields of glass production, processing, and quality inspection, glass gloss is one of the key indicators for evaluating product surface quality, and its test results directly affect the suitability of glass for applications such as architectural decoration, electronic screens, and optical devices. Currently, the industry generally suffers from a lack of dedicated and efficient fixtures for testing glass gloss. Without a dedicated fixture, the glass to be tested is often placed directly on the testing platform. It is prone to displacement or shaking due to slight vibrations of the platform or airflow disturbances, which causes deviations in the reflected light from the glass surface received by the gloss meter. The test data fluctuates greatly and cannot meet the requirements of high-precision testing. In some scenarios, the manual hand-held method of fixing glass not only requires the operator to maintain a stable posture continuously, which is cumbersome and inefficient, but also easily contaminates the glass surface due to hand sweat and stains, or causes local compression deformation and surface scratches due to uneven gripping force, which affects the accuracy of the test and causes glass loss. The existing few simple fixing devices are mostly single-specification designs, which can only be adapted to glass of specific sizes and thicknesses. When testing glass of different specifications, the devices need to be changed frequently, resulting in poor adaptability. Moreover, most devices do not have stable limiting for the angle of the detection light source, and the light source is easily affected by external interference, which further aggravates the detection error and cannot meet the diverse and high-precision requirements of glass gloss testing.

[0004] To achieve the above objectives, this utility model provides the following technical solution: A glass gloss testing fixture includes: Basic support components, including: A horizontally positioned base plate, which is a rigid flat plate structure, is used to support the weight of the entire device; At least two vertically fixed struts are attached to the top of the base plate. The struts are cylindrical and symmetrically distributed along the edge of the top surface of the base plate. A horizontally arranged cross plate is fixedly connected to the end of the support rod away from the bottom plate, and a groove for positioning is provided in the center of its top surface; The detection and positioning components include: Two symmetrical U-shaped frames are fixed to the top surface of the horizontal plate. The openings of the U-shaped frames face upwards, and their inner sidewalls are provided with a smooth and wear-resistant layer. An annular frame that can be movably placed inside a U-shaped frame, wherein the annular frame is a hollow annular structure and its inner diameter is adapted to the outer diameter of the glass to be tested; Two symmetrical U-shaped rods are fixed to the outer wall of the annular frame. The length of the U-shaped rods is greater than the outer diameter of the annular frame, which is used to facilitate the movement of the annular frame. Glass fixing components, including: At least two springs are evenly distributed along the inner sidewall of the annular frame, one end of each spring is fixedly connected to the inner sidewall of the annular frame, and the other end extends toward the center of the annular frame. Each spring has a pressure plate corresponding to a spring. The pressure plate is an arc-shaped plate with one side fixedly connected to the end of the spring away from the annular frame, and the other side is used to fit against the surface of the glass to be tested. Gloss measurement components include: A light source is fixed to one side of the top surface of the base plate, and the light emission direction of the light source is towards the area where the annular frame is located, so as to provide the light source required for detection; A fixing plate is fixed to one side of the top surface of the base plate. The fixing plate is located directly above the light source and is used to assist in positioning the light emission angle of the light source. A gloss meter is fixed to the bottom surface of a fixed plate and positioned opposite the light source, with the detection end of the gloss meter facing the center of the annular frame.
[0005] Preferably, the inner sidewall of the annular frame is provided with a mounting groove for accommodating the spring, the depth of which is adapted to the natural length of the spring, to ensure that the pressure plate does not extend beyond the inner sidewall of the annular frame in the natural state of the spring.
[0006] Preferably, the side of the pressure plate that is in contact with the glass is provided with a silicone anti-slip pad layer. The surface of the silicone anti-slip pad layer is provided with fine texture to enhance the friction between the pressure plate and the glass and prevent the glass from sliding.
[0007] Preferably, a gap is provided between the inner wall of the U-shaped frame and the outer wall of the annular frame, the gap being 1-2mm wide, which facilitates the insertion of the annular frame into the U-shaped frame and also serves to position the annular frame.
[0008] Preferably, the light source is detachably connected to the base plate by bolts, and the base plate has a waist-shaped hole for adjusting the installation height and light emission angle of the light source.
[0009] Compared with the prior art, the beneficial effects of this utility model are: 1. This glass gloss test fixture is stable and protects the glass: The spring inside the ring frame cooperates with the pressure plate, and the elastic extrusion force of the spring is evenly applied to the glass through the pressure plate. This not only achieves stable clamping of the glass and avoids the glass shaking during the test, which affects the accuracy, but also reduces the extrusion damage and scratches on the glass surface through the arc structure of the pressure plate and the possible silicone pad layer, thus protecting the integrity of the glass.
[0010] 2. This glass gloss testing fixture is easy and efficient to operate: The U-shaped bar design on the outside of the ring frame makes it easy for operators to hold and move the ring frame without direct contact with the glass, avoiding hand contamination or external damage to the glass; the ring frame can be flexibly removed or placed in the U-shaped frame, facilitating the loading and unloading of glass, shortening the operation process, and improving testing efficiency.
[0011] 3. This glass gloss testing fixture offers high testing accuracy: The base plate, struts, and cross plate in the basic support assembly form a stable frame, ensuring the overall stability of the device and preventing foundation swaying from interfering with the test; the U-shaped frame's limiting effect on the annular frame, combined with the relatively precise settings of the gloss meter and the light source, ensures that the glass is always in the center of the test area, and the light source angle is stable, allowing the gloss meter to accurately receive reflected light, reducing test errors and improving data reliability.
[0012] 4. This glass gloss test fixture is highly adaptable and flexible: the inner diameter of the ring frame is compatible with the outer diameter of the glass to be tested, which can meet the testing requirements of corresponding glass specifications; the light source can be adjusted in height and angle through the waist-shaped hole on the base plate, which can adapt to the testing of glass of different thicknesses and cope with various testing scenarios.
[0013] 5. This glass gloss testing fixture is durable and easy to maintain: the smooth wear-resistant layer on the inside of the U-shaped frame reduces frictional wear between the ring frame and the U-shaped frame, extending the service life of the components; the light source and the base plate are detachably connected, which facilitates repair or replacement in case of light source failure and reduces maintenance costs.

[0016] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0017] Example: Please refer to the following: Figure 1-4 , A glass gloss testing fixture includes: Basic support components, including: A horizontally positioned base plate 1, which is a rigid flat plate structure, is used to support the weight of the entire device; At least two vertically fixed support rods 2 are fixed to the top of the base plate 1. The support rods 2 are cylindrical rods and are symmetrically distributed along the edge of the top surface of the base plate 1. A horizontally arranged horizontal plate 3 is fixedly connected to the end of the support rod 2 away from the bottom plate 1, and a groove for positioning is provided in the middle of its top surface; The detection and positioning components include: Two symmetrical U-shaped frames 4 are fixed to the top surface of the horizontal plate 3. The openings of the U-shaped frames 4 face upwards, and their inner sidewalls are provided with a smooth and wear-resistant layer. An annular frame 5 can be movably placed inside the U-shaped frame 4. The annular frame 5 is a hollow annular structure, and its inner diameter is adapted to the outer diameter of the glass to be tested. Two U-shaped rods 6 are symmetrically fixed to the outer wall of the annular frame 5. The length of the U-shaped rods 6 is greater than the outer diameter of the annular frame 5, which is used to facilitate the movement of the annular frame 5. Glass fixing components, including: At least two springs 7 are evenly distributed along the inner sidewall of the annular frame 5. One end of each spring 7 is fixedly connected to the inner sidewall of the annular frame 5, and the other end extends toward the center of the annular frame 5. The pressure plate 8 corresponds to each spring 7. The pressure plate 8 is an arc-shaped plate. One side of the pressure plate is fixedly connected to the end of the spring 7 away from the annular frame 5, and the other side is used to fit against the surface of the glass to be tested. Gloss measurement components include: A light source 9 is fixed to one side of the top surface of the base plate 1. The light emission direction of the light source 9 is towards the area where the annular frame 5 is located, and it is used to provide the light source required for detection. A fixing plate 10 is fixed to one side of the top surface of the base plate 1. The fixing plate 10 is located directly above the light source 9 and is used to assist in positioning the light emission angle of the light source 9. A gloss meter 11 is fixed to the bottom surface of the fixing plate 10 and is positioned opposite to the light source 9. The detection end of the gloss meter 11 is directly opposite the center of the annular frame 5. Specifically, basic support components: building a stable testing benchmark. The horizontally set base plate 1 serves as the supporting foundation for the entire device. Through its own rigid flat plate structure, it distributes and bears the weight of all components, ensuring that the bottom of the device is stable when placed, and avoiding the impact of foundation shaking on the detection accuracy. At least two cylindrical struts 2 are symmetrically distributed along the top edge of the base plate 1, vertically connecting the base plate 1 and the horizontal plate 3. On the one hand, the symmetrical distribution of the structural characteristics ensures that the horizontal plate 3 is subjected to balanced forces, and on the other hand, the rigid support capacity of the cylindrical struts keeps the horizontal plate 3 in a horizontal state, providing a stable installation platform for subsequent testing components. The horizontal plate 3 fixed to the top of the strut 2 has a positioning groove in the middle of its top surface, which can assist in the subsequent installation and positioning of the U-shaped frame 4, ensuring that the position of the U-shaped frame 4 is accurate, and indirectly ensuring that the placement of the ring frame 5 and the glass to be tested meets the testing requirements. Detection and positioning components: enabling precise glass alignment The U-shaped frame 4, symmetrically fixed to the top surface of the horizontal plate 3, has an upward-facing structure that facilitates the insertion and removal of the ring frame 5. The smooth and wear-resistant layer on the inner sidewall reduces frictional loss when the ring frame 5 contacts the U-shaped frame 4, and also reduces the jamming phenomenon when the ring frame 5 is inserted, ensuring that the ring frame 5 can be smoothly placed in place. Furthermore, the symmetrical arrangement of the two U-shaped frames 4 can provide stable support for both sides of the ring frame 5, preventing the ring frame 5 from shifting during the testing process. The annular frame 5, which can be placed inside the U-shaped frame 4, has a hollow annular structure that matches the outer diameter of the glass to be tested. It can initially limit the glass from all sides to prevent the glass from moving laterally. The movable nature of the annular frame 5 makes it convenient for operators to fix the glass outside the U-shaped frame 4 first, and then put the annular frame 5 into the U-shaped frame 4 as a whole, thus improving the ease of operation. The U-shaped rods 6, which are symmetrically fixed on the outer wall of the ring frame 5, are longer than the outer diameter of the ring frame 5. Operators can easily move the ring frame 5 by holding the U-shaped rods 6 without directly contacting the ring frame 5 and the glass to be tested, thus avoiding contamination or damage to the glass surface caused by hand dirt or external force. At the same time, it is easy to accurately adjust the ring frame 5 to the center position inside the U-shaped frame 4. Glass clamping assembly: Ensures stable glass clamping Springs 7 are evenly distributed along the inner wall of the annular frame 5. One end is fixed to the annular frame 5, and the other end extends towards the center. When the glass to be tested is placed into the annular frame 5, the glass will squeeze the pressure plate 8, which will compress the springs 7. The elastic characteristics of the springs 7 will generate a reverse compressive force, which is transmitted to the glass surface through the pressure plate 8. At least two evenly distributed springs 7 can ensure that the glass is subjected to balanced force around its perimeter, and prevent the glass from deforming or displacing due to excessive local force. The arc-shaped pressure plate 8, which corresponds one-to-one with the spring 7, has an arc structure that can better fit the glass surface, increase the contact area, and make the squeezing force of the spring 7 act more evenly on the glass. At the same time, it avoids the edge of the pressure plate 8 from scratching the glass surface. One side of the pressure plate 8 is fixed to the spring 7, and the other side is attached to the glass. It plays the role of transmitting the squeezing force of the spring 7 and stabilizing the glass, ensuring that the glass remains fixed in a fixed state and does not shake during the testing process. Gloss detection component: Completes gloss data acquisition. The light source 9, fixed on one side of the top surface of the base plate 1, emits light in the direction of the annular frame 5. It can provide a stable and uniform light source for the glass surface to be tested. The light source is a necessary condition for gloss measurement. Only under the illumination of a standard light source can the gloss meter 11 accurately detect the reflection of light on the glass surface and then calculate the gloss value. The fixing plate 10 located directly above the light source 9 uses its own structure to assist in positioning the light emission angle of the light source 9, preventing the light source 9 from shifting due to slight external impacts or long-term use, ensuring that the light source always illuminates the glass surface at a preset angle, guaranteeing the consistency of detection conditions, and improving the reliability of detection data. The gloss meter 11, which is fixed to the bottom surface of the fixing plate 10 and is positioned opposite to the light source 9, has its detection end facing the center of the annular frame 5, and can accurately receive the light reflected from the glass surface. After the light source 9 provides a stable light source, the gloss meter 11 calculates the gloss value of the glass according to a preset algorithm by detecting parameters such as the intensity and angle of the reflected light, thus completing the core detection function. In the embodiment: the inner sidewall of the annular frame 5 is provided with a mounting groove for accommodating the spring 7. The depth of the mounting groove is adapted to the natural length of the spring 7 to ensure that the pressure plate 8 does not exceed the inner sidewall of the annular frame 5 in the natural state of the spring 7. Specifically, by creating a mounting groove on the inner wall of the annular frame 5 that matches the natural length of the spring 7, the spring 7 can be fully or mostly contained within the mounting groove when in its natural state, ensuring that the pressure plate 8 does not protrude beyond the inner wall of the annular frame 5. This structural design prevents the pressure plate 8 from obstructing the smooth insertion of the glass before it is placed in the frame, ensuring that the glass can be easily placed within the annular frame 5. At the same time, the mounting groove can limit the movement of the spring 7, preventing it from shifting laterally during compression or rebound, ensuring that the spring force of the spring 7 is always transmitted radially along the annular frame 5 to the pressure plate 8, thereby ensuring the stability and reliability of the glass clamping. In this embodiment: a silicone anti-slip pad layer is provided on the side of the pressure plate 8 that is in contact with the glass. The surface of the silicone anti-slip pad layer is provided with fine texture to enhance the friction between the pressure plate 8 and the glass and prevent the glass from sliding. Specifically, a silicone anti-slip pad is provided on the side of the pressure plate 8 that is in contact with the glass. The silicone material itself has good elasticity and friction, which can increase the contact friction between the pressure plate 8 and the glass surface. At the same time, the fine texture on the surface of the silicone anti-slip pad can further increase the coefficient of friction, effectively preventing the glass from sliding during the testing process due to external forces such as slight vibration, heat dissipation airflow from the light source 9, or its own gravity. In addition, the silicone material is soft and can act as a buffer when in contact with the glass, avoiding hard compression damage to the glass surface caused by the pressure plate 8. This ensures both the glass fixation effect and the protection of the glass surface, ensuring that the test results are not affected by damage to the glass surface. In the embodiment: a gap is provided between the inner wall of the U-shaped frame 4 and the outer wall of the annular frame 5. The width of the gap is 1-2mm, which facilitates the insertion of the annular frame 5 into the U-shaped frame 4 and also serves to position the annular frame 5. Specifically, a gap of 1-2mm is set between the inner wall of the U-shaped frame 4 and the outer wall of the annular frame 5. This gap width is neither too large, which would cause the annular frame 5 to wobble significantly within the U-shaped frame 4 and affect the glass positioning accuracy, nor too small, which would cause excessive frictional resistance when the annular frame 5 is placed in or removed, resulting in inconvenience in operation. In other words, the 1-2mm gap can ensure that the annular frame 5 can be smoothly placed into the U-shaped frame 4, while limiting the horizontal displacement of the annular frame 5 through the limiting effect of the inner wall of the U-shaped frame 4 on the outer wall of the annular frame 5. This keeps the annular frame 5 in the preset detection position within the U-shaped frame 4, ensuring that the center of the glass to be tested is aligned with the detection end of the gloss meter 11, thereby improving the accuracy of the detection data. In this embodiment: the light source 9 is detachably connected to the base plate 1 by bolts, and the base plate 1 has a waist-shaped hole for adjusting the installation height and light emission angle of the light source 9; Specifically, the light source 9 is detachably connected to the base plate 1 via bolts, facilitating disassembly, repair, or replacement of the light source 9 in case of malfunction, thus reducing maintenance costs. Simultaneously, the oblong hole on the base plate 1 allows the bolts some room to move within it. Operators can loosen the bolts and adjust the installation position of the light source 9 along the length of the oblong hole, thereby changing the installation height and emission angle of the light source 9. Adjusting the emission angle ensures that the light emitted by the light source 9 illuminates the glass surface to be inspected at a standard detection angle, while adjusting the installation height adapts to glass of different thicknesses, ensuring that the light always effectively covers the glass inspection area, avoiding deviations in inspection data due to improper light source angle or height, and further improving the flexibility and accuracy of the inspection. In this embodiment: the controller is an existing structure, and the control circuit can be implemented by simple programming by those skilled in the art. It is common knowledge in the art, and it is only used without modification. Therefore, the control method and circuit connection will not be described in detail.
[0018] Working principle: In use, first, use the U-shaped rod 6 on the annular frame 5 to remove the U-shaped frame 4. Place the glass to be tested into the annular frame 5. The glass presses against the pressure plate 8, compressing the spring 7. The reverse force of the spring 7, through the pressure plate 8, fixes the glass inside the annular frame 5. Then, place the annular frame 5 back into the U-shaped frame 4 and adjust it to be centered. Subsequently, the light source 9 on the base plate 1 emits light towards the glass. The fixing plate 10 assists in positioning the angle of the light source. The gloss meter 11 on the bottom surface of the fixing plate 10 above the horizontal plate 3 receives the reflected light from the glass, detects and calculates the gloss, and completes the test. The base plate 1 and the support rod 2 form a basic support to ensure the stability of the device.
[0019] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
