Description

Technical Field

[0001] The utility model relates to the technical field of glass stress detection, in particular to a stress detection device for fireproof tempered glass. Background Art

[0002] Glass stress detection technology is a key means to evaluate the quality and safety of glass. During the production and processing of glass, internal stress will be generated due to factors such as temperature gradient and external force. If the stress distribution is uneven or too large, it is easy to cause the glass to explode or break, threatening safety. At present, common detection technologies include polarized stress meter method, which is based on the principle of birefringence. It observes the interference color of glass through polarized light and judges the stress size and distribution according to the color sequence. The astigmatic interferometry method can accurately measure the stress on the surface and inside of the glass, and can provide stress values ​​and three-dimensional distribution diagrams with high accuracy. There is also laser speckle interferometry, which uses laser speckle changes to detect stress. It has the advantages of non-contact and full-field measurement. Different detection technologies have their own advantages and disadvantages. In practical applications, it is necessary to reasonably select the detection method based on factors such as glass type, detection accuracy requirements and cost to ensure glass quality and safety.

[0003] In the prior art, the stress detection device for fire-resistant tempered glass generally relies on manual handheld detection instruments to be moved and adjusted between different areas to complete comprehensive detection, which reduces the detection efficiency. Slight hand shaking or uneven force of the detection personnel will cause a gap between the detection instrument and the glass surface, affecting the accuracy of the detection data, and re-detection has to be performed, resulting in reduced efficiency. The detection personnel need to divide the glass surface detection area based on experience, which is prone to unreasonable area division, omissions or repeated detection. Some areas may be detected multiple times, while some areas may be ignored, resulting in low detection efficiency and inaccurate results. Therefore, we need a stress detection device for fire-resistant tempered glass. Utility Model Content

Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0023] The embodiment of the present invention provides a stress detection device for fireproof tempered glass, as Figure 1 , Figure 4 , Figure 5 and Figure 6As shown in the figure, it includes a stress detection box 1. A box door 2 is provided on one side of the stress detection box 1. An operation panel 3 is provided on the surface of the stress detection box 1. A stress detection component 4 is provided inside the stress detection box 1. A support frame 5 is provided inside the stress detection box 1. A positioning component 6 is slidably connected inside the support frame 5. The stress detection component 4 includes a first electric slide 401. The first electric slide 401 includes a slide rail and a slide table. The slide table on the first electric slide 401 is fixedly connected to a top plate 402. The bottom of the top plate 402 is fixedly connected to a frame 403. A mounting motor 404 is fixedly connected to the top of the frame 403. The output end of the mounting motor 404 is fixedly connected to a turntable 405. A connecting rod 406 is hinged to the bottom of the turntable 405. One end of the connecting rod 406 is hinged to a moving frame 407. A chute 408 is provided inside the moving frame 407. A slide bar 409 is slidably connected inside the chute 408. A first gear 410 is rotatably connected inside the moving frame 407. The outer wall of the first gear 410 is meshed with a first rack 411. A lead screw 412 is rotatably connected inside the first gear 410. A guide sleeve 413 is threadedly connected to the outer wall of the lead screw 412. The bottom of the guide sleeve 413 is fixedly connected to a stress detector body 414. Start the mounting motor 404 in the frame 403, so that the mounting motor 404 drives the turntable 405 to rotate. The turntable 405 drives the moving frame 407 to move by relying on the connecting rod 406, so that the moving frame 407 slides along the outer wall of the slide bar 409 by relying on the two chutes 408 on both sides. In addition, when the moving frame 407 moves, the first gear 410 inside the moving frame 407 rotates along one side of the first rack 411, driving the two lead screws 412 to rotate, so that the lead screws 412 rotate inside the guide sleeve 413, and the guide sleeve 413 drives the stress detector body 414 at the bottom to adjust its position along the outer wall of the lead screw 412, which is suitable for detecting glass of different sizes. At the same time, the stress detector body 414 can comprehensively detect different areas of glass of different sizes, improving the detection efficiency and saving manpower.

[0024] Further, as Figure 5 and Figure 6 shown, the turntable 405 and the moving frame 407 form a movable structure through the connecting rod 406, and the connecting rod 406 is arranged between the turntable 405 and the moving frame 407, strengthening the connection effect between the turntable 405 and the connecting rod 406. When the turntable 405 rotates, it drives the connecting rod 406 to push the moving frame 407 to move, facilitating the adjustment of the detector to different positions.

[0025] Further, as Figure 5 and Figure 6As shown, the moving frame 407 is rotationally structured with the lead screw 412 through the first gear 410. There are two lead screws 412 on the first gear 410, and the two lead screws 412 are symmetrically arranged with the perpendicular bisector of the first gear 410 as the axis of symmetry, strengthening the connection effect between the moving frame 407 and the first gear 410, enabling the moving frame 407 to drive the first gear 410 to rotate along the first rack 411, and enabling the first gear 410 to drive the lead screws 412 on both sides to rotate.

[0026] In a further preferred embodiment of the present utility model, as Figure 1 , Figure 2 and Figure 3 shown, the positioning assembly 6 includes a second electric sliding table 601. The second electric sliding table 601 includes a slide rail and a slide table. A driving motor 602 is fixedly connected to the slide table on the second electric sliding table 601. A pulley 603 is fixedly connected to the output shaft of the driving motor 602. A connecting belt 604 is sleeved on the outer wall of the pulley 603. The upper belt of the connecting belt 604 is fixedly connected to a first placement rack 605. A protective pad 606 is fixedly connected to the top of the first placement rack 605. A moving rod 607 is slidably connected to the bottom of the first placement rack 605. The lower belt of the connecting belt 604 is fixedly connected to a second placement rack 608. The second placement rack 608 is slidably connected to the moving rod 607. The glass to be detected is stably placed on the protective pad 606 on the top of the first placement rack 605 and the second placement rack 608. The protective pad 606 can effectively buffer the pressure and prevent the glass from being scratched. Start the driving motor 602. The driving motor 602 drives the connecting belt 604 to rotate by means of the pulley 603. The upper belt and the lower belt of the connecting belt 604 exert force synchronously, accurately pulling the first placement rack 605 and the second placement rack 608 to slide stably along the outer wall of the moving rod 607, easily realizing the flexible adjustment of the distance between the two, meeting the positioning requirements of glass of different sizes. After positioning, start the second electric sliding table 601 synchronously, so that the slide table drives the glass to move smoothly and accurately along the bottom guide rail, and transports the positioned glass accurately into the stress detection box 1.

[0027] Furthermore, as Figure 3 shown, the first placement rack 605 and the second placement rack 608 are arranged on the connecting belt 604, and the first placement rack 605 and the second placement rack 608 are symmetrically arranged with the perpendicular bisector of the connecting belt 604 as the axis of symmetry, facilitating the arrangement of the first placement rack 605 and the second placement rack 608. When the connecting belt 604 rotates, the upper belt pulls the first placement rack 605 to approach the middle, and at the same time, the lower belt pulls the second placement rack 608 to approach the middle synchronously, achieving the purpose of adjusting the distance between the first placement rack 605 and the second placement rack 608.

[0028] Furthermore, as Figure 3As shown, the slide on the second electric slide table 601 forms a sliding structure with the first placement rack 605 through the moving rod 607, and the outer wall of the moving rod 607 is in close contact with the inner wall of the first placement rack 605, strengthening the connection effect between the moving rod 607 and the first placement rack 605, enabling the first placement rack 605 to slide along the outer wall of the moving rod 607 and providing stable support when the first placement rack 605 moves.

[0029] Working principle: During use, place the glass to be detected stably on the protective pads 606 on the tops of the first placement rack 605 and the second placement rack 608. The protective pads 606 can effectively buffer the pressure and prevent the glass from being scratched. Then start the drive motor 602. The drive motor 602 drives the connecting belt 604 to rotate by means of the pulley 603. The upper belt and the lower belt of the connecting belt 604 exert force synchronously, precisely pulling the first placement rack 605 and the second placement rack 608 to slide stably along the outer wall of the moving rod 607, easily realizing the flexible adjustment of the distance between the two to meet the positioning requirements of glass of different sizes. After positioning, start the second electric slide table 601 synchronously, so that the slide table drives the glass to move smoothly and precisely along the bottom guide rail, and transports the positioned glass accurately into the stress detection box 1, making full preparations for subsequent detection. The whole process is efficient and stable, greatly improving the convenience and accuracy of glass stress detection, realizing the automatic connection of the detection process, and improving work efficiency. In addition, during detection, according to the size of the glass to be detected, start the installation motor 404 in the frame 403, so that the installation motor 404 drives the turntable 405 to rotate. The turntable 405 drives the moving frame 407 to move by means of the connecting rod 406, enabling the moving frame 407 to slide along the outer wall of the sliding rod 409 by relying on the chutes 408 on both sides. In addition, when the moving frame 407 moves, the first gear 410 in the moving frame 407 rotates along one side of the first rack 411, driving the lead screws 412 on both sides to rotate, so that the lead screws 412 rotate in the guide sleeves 413. The guide sleeves 413 drive the stress detection machine body 414 at the bottom to adjust its position along the outer wall of the lead screws 412, suitable for detecting glass of different sizes. At the same time, during detection, the stress detection machine body 414 directly measures the glass stress by relying on the contact optical detection method of the detector. By attaching the polarized light sensor to the glass surface and using the birefringence effect and the principle of optical interference, the stress detection machine body 414 can comprehensively detect different areas of glass of different sizes, improving the detection efficiency and saving manpower.
