Description

Technical Field

[0001] This utility model relates to the field of glass quality inspection technology, and in particular to a stress testing device for high-strength tempered glass. Background Technology

[0002] High-strength tempered glass is widely used in applications requiring high safety, strength, and heat resistance, such as building curtain walls, transportation vehicles, and electronic display equipment. Because tempered glass undergoes high-temperature heating and rapid cooling during manufacturing, significant residual stress forms within it. This stress significantly impacts the glass's strength and breakage mode. To ensure the quality stability and safety of tempered glass, stress testing is typically performed before it leaves the factory. Stress testing equipment, a key component of the glass testing process, is used to assess the stress state inside or on the surface of tempered glass, providing crucial information for product quality control and engineering applications.

[0003] Existing stress testing devices for tempered glass typically employ techniques such as polarized light detection, pressure sensing, or image analysis to assess the stress state of the glass. For example, some devices analyze stress interference patterns by setting up polarized light sources and analyzers; some devices combine pressure sensors with data acquisition modules for quantitative detection; and some systems integrate camera devices and image processing algorithms to assist in determining stress distribution. However, in existing technologies, the camera position is mostly fixed or manually adjusted, which is not only inefficient but also prone to blurry images due to positional deviations, thus affecting the accuracy of stress testing results. Therefore, a high-strength tempered glass stress testing device is proposed to address these issues. Utility Model Content

[0027] Reference Figures 1-3This utility model provides an embodiment of a high-strength tempered glass stress testing device, comprising a testing box 1, a light shield 2 fixedly connected to the top of the testing box 1, and a light shield curtain that can be installed on the front side of the light shield 2 to achieve complete light blocking. Both the testing box 1 and the light shield 2 are equipped with a drive mechanism, and the light shield 2 is equipped with a swing mechanism. The testing box 1 and the light shield 2 are equipped with a testing mechanism for testing the tempered glass. The swing mechanism includes a sliding plate 4, which is disposed inside the light shield 2 and connected to the drive mechanism at the top. Activating the drive mechanism at the top... This allows the slide plate 4 to move inside the sunshade 2. A turntable 5 is rotatably connected inside the slide plate 4. A gear 6 is fixedly connected to the top of the turntable 5, passing through the side wall of the slide plate 4. A rack 3 is fixedly connected to the top of the inner wall of the sunshade 2. The gear 6 meshes with the rack 3. As the slide plate 4 moves, the gear 6 rotates along the rack 3, simultaneously causing the turntable 5 to deflect. A fixing block 12 is fixedly connected to the bottom of the slide plate 4. A limit rod 8 is slidably connected inside the fixing block 12. A movable plate 7 is fixedly connected to the side wall of the limit rod 8. A fixing frame 9 is fixedly connected to the top of the movable plate 7. The bottom of the turntable 5 is fixedly connected to... A guide block 10 is attached, located on the outer side of the bottom of the turntable 5. The guide block 10 is set inside the fixed frame 9. When the guide block 10 moves with the turntable 5, it will simultaneously drive the fixed frame 9 to move. When the fixed frame 9 moves, the moving plate 7 will move laterally under the restriction of the limiting rod 8. When the guide block 10 moves from the front and rear sides to the left and right sides, it will slide in the fixed frame 9, so it will not drive the moving plate 7 to move in the front and rear sides. The drive mechanism includes a motor 15, a lead screw 13, and a slide rail 16. The lead screw 13 is rotatably connected to the detection box 1 and the light shield. Inside the cover 2, the slide rail 16 is fixedly connected to the side wall of the detection box 1 and the light shield 2. The top motor 15 is fixedly connected to the side wall of the light shield 2, and its output end is connected to one end of the top lead screw 13. The detection box 1 is fixedly connected to the fixed base 14. The bottom motor 15 is fixedly connected to the side wall of the fixed base 14, and its output end is connected to one end of the bottom lead screw 13. One side of the slide plate 4 is threaded to the outside of the top lead screw 13, and the other side of the slide plate 4 is slidably connected to the side wall of the top slide rail 16. By starting the top motor 15, the lead screw 13 connected to it can be rotated, which allows the slide plate 4 to move.

[0028] Reference Figures 1-3The testing box 1 is equipped with a clamp 18, which is a two-jaw clamp using existing detachable technology. The tempered glass is fixed in place by the simultaneous movement of the two side clamps towards the center. Connecting blocks 19 are fixedly connected to both sides of the clamp 18. One connecting block 19 is threaded to the outside of the bottom lead screw 13, and the other connecting block 19 is slidably connected to the side wall of the bottom slide rail 16. Starting the bottom motor 15 rotates the lead screw 13, which in turn moves the clamp 18 via the connecting blocks 19, causing the tempered glass to move into the testing box 1. A roller 17 is rotatably connected between the fixing seats 14. The roller 17 and the clamp 18 are at the same horizontal level. When placing the tempered glass, it is placed on top of the roller 17 and the clamp 18, and then the clamp 18... The tempered glass is clamped and fixed on one side. As the clamp 18 moves, the tempered glass slides on the roller 17. The detection mechanism includes a camera 11, a polarizer 1 20, a polarizer 21, and a light box 22. The side wall of the camera 11 is fixedly connected to the bottom of the moving plate 7. The side wall of the polarizer 1 20 is fixedly connected to the bottom of the moving plate 7. The polarizer 1 20 and the light box 22 are all set inside the detection box 1. The polarizer 1 20 is located at the top of the clamp 18, and the polarizer 21 is located at the bottom of the clamp 18. The camera 11 can take pictures of the tempered glass between the polarizer 1 20 and the polarizer 21 and perform grayscale processing on the pictures. If there is obvious uneven brightness in some areas of the picture, it indicates that there is stress in the glass. The light box 22 is located at the bottom of the polarizer 21 and is used to supplement the light for the equipment.

[0029] Working principle: When using this equipment to perform stress testing on tempered glass, the tempered glass is first placed on top of the rollers 17 and clamps 18. Then, the clamps 18 hold and fix one side of the tempered glass. Subsequently, the motor 15 at the bottom is started, driving the lead screw 13 connected to it to rotate. This, in turn, drives the clamps 18 to move through the connecting block 19, causing the tempered glass to move into the testing chamber 1. Once the tempered glass is completely inside the testing chamber 1, the light box 22 illuminates the interior of the testing chamber 1, and the camera 11 takes a picture of the tempered glass between polarizer 1 20 and polarizer 21 for testing. The picture is then processed into grayscale. If there is obvious uneven brightness in certain areas of the photo, it indicates that there is stress in the glass. For more accurate detection, the motor 15 at the top can be started to drive the lead screw 13 connected to it to rotate, thereby moving the slide plate 4. While the slide plate 4 is moving, the gear 6 will rotate along the rack 3 and simultaneously drive the turntable 5 to deflect. When the turntable 5 deflects, the guide block 10 will move in a circular motion with the turntable 5 and drive the fixed frame 9 to move, thereby causing the moving plate 7 to move laterally under the restriction of the limit rod 8, thereby changing the position of the camera 11 and enabling it to take more accurate pictures of the tempered glass, ensuring the accuracy of the detection.

[0030] The rest of this embodiment is the same as that in Embodiment 1. Features not explained in this embodiment are explained using the methods in Embodiment 1, and will not be repeated here.

[0031] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
