Description

Technical Field

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

[0002] Glass stress testing technology is a key means of assessing glass quality and safety. During the production and processing of glass, internal stress is generated due to factors such as temperature gradients and external forces. If the stress distribution is uneven or excessive, it can easily lead to spontaneous breakage and shattering, threatening safety. Currently, common testing technologies include the polarized light stress meter method, which is based on the principle of birefringence and observes the interference colors of the glass through polarized light. The stress magnitude and distribution are determined according to the color sequence. The astigmatic interferometry method can accurately measure the stress on the glass surface and inside, providing stress values ​​and three-dimensional distribution maps with high accuracy. There is also the laser speckle interferometry method, which uses changes in laser speckle to detect stress and has the advantages of non-contact and full-field measurement. Different testing technologies have their own advantages and disadvantages. In practical applications, it is necessary to rationally select the testing method based on factors such as glass type, testing accuracy requirements, and cost to ensure glass quality and safety in use.

[0003] In existing technologies, stress testing of tempered glass is performed using both manual and mechanical methods. Manual operation is labor-intensive, and the edges of tempered glass are prone to scratches. Mechanical structures can only perform reciprocating testing on individual tempered glass pieces, which is inefficient and cannot achieve continuous linear testing, making them inconvenient to use.

[0025] Reference Figure 1-4This utility model discloses a stress testing device for fire-resistant tempered glass, comprising: a support platform 1, a testing box 2 fixedly connected above the support platform 1, and first threaded rods 4 penetrating both sides of the top of the testing box 2. The extension length of the electric telescopic rod 3 can be precisely controlled by the first threaded rods 4. A limiting nut 5 and the first threaded rod 4 are threaded to different heights, allowing the lifting plate 10 to descend during the extension of the electric telescopic rod 3, thus causing the first threaded rod 4 to descend along with it. Simultaneously, due to the limiting nut 5, the descent of the lifting plate 10 is restricted, maintaining a specified descent depth and preventing damage to the stress testing machine 12 and the tempered glass. The bottom end of the first threaded rod 4 is fixed... A lifting plate 10 is fixedly connected, and several second threaded rods 18 are rotatably connected inside the lifting plate 10. A stress testing machine 12 is threadedly connected to the middle of the second threaded rods 18. During testing, the stress testing machine 12 uses the contact optical detection method of the detector to directly measure the glass stress by attaching a polarized light sensor to the surface of the tempered glass and utilizing the birefringence effect and the principle of optical interference. At the same time, the stress testing machine 12 can perform comprehensive testing on different areas of glass of different sizes, which improves the testing efficiency. A support plate 13 is set on one side of the middle of the upper surface of the support platform 1. An electric telescopic rod 3 is fixedly connected to the top center of the testing box 2. The extension end of the electric telescopic rod 3 is fixedly connected to the lifting plate 10.

[0026] A first motor 7 is fixedly connected to one side of the bottom center of the support platform 1. When the first motor 7 rotates in the opposite direction, the support plate 13 descends. Then, through the extension of the small telescopic rod 17, the drive roller 15 is lifted. Driven by the third motor 16, the tempered glass is conveyed and discharged. The first motor 7 drives the threaded column 9 to rotate and engage with the support frame 8, thus achieving threaded movement. The drive end of the first motor 7 is fixedly connected to the threaded column 9, and the middle of the threaded column 9 is threadedly connected to the support frame 8. The support frame 8 lifts the support plate 13. At the same time as lifting, the electric telescopic rod 3 extends, lowering the lifting plate 10. The top of the support frame 8 is fixedly connected to the support plate 13. Several rubber support seats 14 are fixedly connected to the top of the support plate 13. Small telescopic rods 17 are fixedly connected to the four corners of the bottom of the support plate 13. When the small telescopic rods 17 descend, the tempered glass is supported by the rubber support seats 14. A support rod is fixedly connected to the drive end of the support plate 13. A drive roller 15 is rotatably connected between the support rods. A third motor 16 is fixedly connected to one side of the support rod. The third motor 16 drives the drive roller 15 to rotate, placing the tempered glass above the support plate 13. The drive end of the third motor 16 is fixedly connected to the drive roller 15. Both ends of the upper surface of the support platform 1 are rotatably fitted with conveyor rollers 6. The fireproof tempered glass is placed above the conveyor rollers 6, and then the fireproof tempered glass on the conveyor rollers 6 is pushed into the interior of the testing box 2 by an external drive device. The middle of the first threaded rod 4 is threadedly connected to a limit nut 5. The two sides of the lifting plate 10 are fixedly connected to a second motor 11. When the testing position needs to be adjusted, the second motor 11 drives the second threaded rod 18 to rotate. After rotation, it engages with the stress testing machine 12 through a thread, thus realizing threaded movement. The drive end of the second motor 11 and the second threaded rod 18 are fixedly connected.

[0027] Working Principle: In operation, fire-resistant tempered glass is first placed above the conveyor roller 6. Then, an external drive pushes the glass into the testing box 2. Once inside, it is supported by the drive roller 15, which is rotated by the third motor 16, positioning the tempered glass above the support plate 13. The small telescopic rod 17 then descends, supporting the tempered glass via the rubber support seat 14. Simultaneously, the first motor 7 drives the threaded column 9 to rotate, engaging with the support frame 8 to achieve threaded movement. This lifts the support plate 13 via the support frame 8. Simultaneously, the electric telescopic rod 3 extends, lowering the lifting plate 10. The stress testing machine 12 contacts the tempered glass. The extension length of the electric telescopic rod 3 can be precisely controlled by the first threaded rod 4. The limit nut 5 rotates with the first threaded rod 4 to different heights, controlling the lifting process during the extension of the electric telescopic rod 3. The lowering of plate 10 causes the first threaded rod 4 to descend as well. Simultaneously, the limiting nut 5 restricts the further descent of the lifting plate 10, maintaining the designated descent depth and preventing damage to the stress testing machine 12 and the tempered glass. During testing, the stress testing machine 12 uses a contact-type optical detection method, attaching a polarized light sensor to the surface of the tempered glass and utilizing the birefringence effect and optical interference principle to directly measure the glass stress. This allows the stress testing machine 12 to comprehensively test different areas of glass of different sizes, improving testing efficiency. When adjustment of the testing position is required, the second motor 11 drives the second threaded rod 18 to rotate. After rotation, it engages with the stress testing machine 12 via a threaded connection, enabling threaded movement and adjustment for different positions. After testing, the first motor 7 rotates in the opposite direction, the support plate 13 descends, and then the extension of the small telescopic rod 17 lifts the drive roller 15. Driven by the third motor 16, the tempered glass is conveyed and discharged.
