Abstract
Description
Technical Field
[0001] The present invention relates to the technical field of glass detection, and in particular to a non-destructive tempered glass self-explosion hidden danger detection device and method. Background Art
[0002] Tempered glass is a safety glass that has been treated with controlled heat or chemical treatment to increase the strength of ordinary glass. The compressive stress on its surface makes it stronger and more stable than ordinary flat glass. In the actual production process, ordinary flat glass is heated in a heating furnace to a temperature close to the softening temperature of the glass. The internal stress is eliminated through its own deformation. The glass is then removed from the heating furnace and high-pressure cold air is blown onto both sides of the glass using a multi-head nozzle, causing it to cool rapidly and evenly to room temperature. This type of glass is in a stress state of internal tension and external compression. Due to the surface stress, tempered glass also has the characteristic of automatically bursting without direct mechanical external force. This is called self-explosion of tempered glass. The reason for this situation is that there are stones, impurities, and bubbles in the glass: impurities in the glass are the weak points of tempered glass and also the stress concentration points; precisely because of this self-explosion characteristic, it is necessary to eliminate the risk of self-explosion of tempered glass after its production is completed.
[0003] Existing detection equipment works by applying external force to fixed positions of tempered glass. Some tempered glass with slight potential for self-explosion often does not break directly after being compressed. Instead, after a certain period of use, the internal stress difference gradually increases and then explodes. During the detection process, relying solely on whether the tempered glass is shattered as the basis for judgment is not rigorous enough and cannot effectively eliminate the risk of tempered glass self-explosion.

[0014] A detection method of a non-destructive tempered glass self-explosion hidden danger detection device, comprising: S1: Insert the tempered glass to be tested and the standard sample into the slots respectively, so that the pressure roller is in close contact with the upper surface of the tempered glass; S2: The second motor drives the two first sliders to move toward the center to adjust the liquid volume in the second chamber. Then, the synchronous motor drives the built-in rotating drum to rotate. The different weights in the eccentric chamber generate different downward pressures to meet the requirements of pressure resistance testing of tempered glass of different specifications. S3: The first motor drives the movable crossbeam to move leftward, and the pressure roller slides horizontally on the upper surface of the tempered glass body. If the potentiometer set at the sliding position of the first round rod and the second round rod detects relative sliding, it means that the internal stress of the tempered glass to be tested is uneven compared with the standard sample. If the tilt sensor detects a change in the angle, it means that there is a bulge on the surface of the tempered glass to be tested. S4: After the pressure roller slides one stroke, the pressure sensor measures the pressure distribution values at both ends of the tempered glass to be tested and the standard sample. By comparing the pressure values of the pressure sensors at the corresponding points at the same position in the two groups and the pressure values of the pressure sensors at the symmetrical points on both sides of the same group, if there is a difference in the values, it means that the internal stress of the tempered glass to be tested is uneven.
[0015] Compared with the prior art, the present invention has the following beneficial effects: 1. The present invention uses two sets of pressure rollers to simultaneously apply downward pressure to the upper surfaces of the tempered glass to be tested and the tempered glass of the standard sample. The two sets of tempered glass bodies bend downward due to the downward pressure, causing deformation. The two sets of pressure rollers move laterally synchronously. If the lateral movement positions at the same node are the same, the deformation amount between the tempered glass to be tested and the standard sample is different, which is directly reflected by the different horizontal heights of the two sets of pressure rollers. The first and second round rods are provided to slide relative to each other. A potentiometer provided at the sliding connection between the first and second round rods measures the relative sliding distance and issues an alarm to remind personnel that the sample to be tested is unqualified. The measured relative sliding distance is used to determine the degree of internal stress nonuniformity between the sample to be tested and the standard sample. 2. If there are stones or impurities inside the tempered glass to be tested, the stress concentration in the area around the stones will increase exponentially during the bending process, which may form a bulge on the surface of the tempered glass. When the pressure roller passes over the bulge, it will tilt. The tilt sensor measures the tilt angle and issues an alarm. The measured tilt angle can be used to determine the degree of defect in the tempered glass to be tested. 3. After the pressure roller slides from one side of the tempered glass body to the other side, this is considered a stroke. The pressure sensor in the rubber pad measures the pressure value within the stroke. The pressure value of the pressure sensor on one side of the tempered glass body is recorded as G, and the pressure value of the pressure sensor on the other side is recorded as G'. If the values of G and G' at symmetrical points at the same node are different; or if the pressure values of the pressure sensors at the same points in the control group and the test group are different, it means that the internal stress of the tempered glass under test is uneven; 4. The present invention uses a second motor to drive the first slider to slide toward the center, injecting the liquid in the first cavity into the second cavity, thereby adjusting the eccentric weight inside the pressure roller. Driven by the synchronous motor, the built-in rotating roller rotates, driving the eccentric weight to continuously generate a large downward force on the tempered glass body. This downward force is much greater than the pressure generated by the pressure roller weight alone, thereby amplifying the difference in values measured by the two sets of pressure sensors and inclination sensors, as well as the sliding distance measured by the potentiometer, thereby amplifying the defect difference between the sample to be tested and the standard sample.

[0020] In this embodiment, the support assembly includes a support leg 2 and a rectangular rod 4. The support leg 2 and the rectangular rod 4 are rotatably connected via a damping shaft 3. A slot 5 is provided on the side of the rectangular rod 4 for inserting the tempered glass body 1. A rubber pad 6 is provided inside the slot 5. In this embodiment, specifically: the sliding contact assembly includes a first vertical rod 13, a second vertical rod 14 is slidably connected inside the first vertical rod 13, a connecting block 15 is fixedly connected to the bottom end of the second vertical rod 14, a first spring 17 is connected between the first vertical rod 13 and the connecting block 15, a pressure roller 16 is rotatably connected to the bottom of the connecting block 15, a counterweight 18 is provided on the side where the two pressure rollers 16 are close to each other, the pressure rollers 16 are in sliding contact with the tempered glass body 1, and downward pressure is applied to the tempered glass body 1 by the pressure rollers 16, so that the tempered glass body 1 is in a compressed state, so as to detect whether the internal stress distribution thereof is uniform; In this embodiment, specifically: the synchronization detection mechanism includes a first round rod 19 and a second round rod 20, the first round rod 19 and the second round rod 20 are slidably connected, the first round rod 19 is rotatably connected to the counterweight 18 of the pressure roller 16 on one side, and the second round rod 20 is rotatably connected to the counterweight 18 of the pressure roller 16 on the other side. An inclination sensor 35 is provided inside the counterweight 18, which can measure and record the inclination angle of the pressure roller 16. A potentiometer is provided at the sliding connection between the first round rod 19 and the second round rod 20, and the relative sliding distance between the first round rod 19 and the second round rod 20 can be measured and recorded by the potentiometer; It should be noted that the internal stress of the standard sample tempered glass should be evenly distributed and free of impurities to ensure that the internal stress remains evenly distributed under pressure. The tempered glass to be tested will inevitably produce different stress distributions on the glass surface due to uneven heating or cooling during the tempering production process. In the actual testing process, tempered glass with uneven internal stress will bend under the action of external force. The side with less stress may show more obvious bending deformation due to lower local compressive strength; the side with greater stress has higher residual compressive stress, relatively stronger bending resistance, and may have less deformation. For tempered glass with stones or impurities inside, the stress concentration in the area around the stones increases exponentially during the bending process, which may form bulges on the surface of the tempered glass. The present invention applies downward pressure to the upper surfaces of the tempered glass to be tested and the tempered glass of the standard sample at the same time by setting two sets of pressing rollers 16. The two sets of tempered glass bodies 1 bend downward due to the downward pressure and produce deformation. The two sets of pressing rollers 16 move laterally synchronously. If the lateral movement positions at the same node are the same, the deformation amounts between the tempered glass to be tested and the standard sample are different, which is directly reflected by the different horizontal heights of the two sets of pressing rollers 16. The first round rod 19 and the second round rod 20 are set to slide relative to each other. The potentiometer set at the sliding connection between the first round rod 19 and the second round rod 20 measures the relative sliding distance and issues an alarm to remind the staff that the sample to be tested is unqualified. The measured relative sliding distance can be used to know the degree of internal stress unevenness of the sample to be tested compared with the standard sample. If there are stones or impurities inside the tempered glass to be tested, the bending During the process, the stress concentration in the area around the stone increases exponentially, which may form a bulge on the surface of the tempered glass. When the pressure roller 16 passes through the bulge, it will tilt. The tilt angle is measured by the tilt sensor 35 and an alarm is issued. The degree of defect of the tempered glass to be tested is known by the measured tilt angle. After the pressure roller 16 slides from one side of the tempered glass body 1 to the other side, this is a stroke. The pressure sensor 7 in the rubber pad 6 measures the pressure value within the stroke. The pressure value of the pressure sensor 7 on one side of the tempered glass body 1 is recorded as G, and the pressure value of the pressure sensor 7 on the other side is recorded as G'. If the values of G and G' at the same node are different at the symmetrical points; or the pressure values of the pressure sensors 7 at the corresponding points at the same position in the control group and the test group are different, it means that the internal stress of the tempered glass to be tested is uneven. In this embodiment, specifically: the frame assembly includes two U-shaped frames 8, two square rods 9 are fixedly connected between the two U-shaped frames 8, a movable crossbeam 11 is slidably connected to the square rod 9, and the translation assembly includes a first screw 10 and a first motor 12, the first screw 10 is rotatably connected to the two U-shaped frames 8, the movable crossbeam 11 is threadedly connected to the first screw 10, the first motor 12 is fixedly connected to the U-shaped frame 8, and the output shaft end of the first motor 12 is fixedly connected to the first screw 10; In this embodiment, specifically: a downward pressure adjustment component is provided inside the pressure roller 16 for adjusting the downward pressure applied by the pressure roller 16 to the upper surface of the tempered glass body 1, and the downward pressure adjustment component includes a built-in rotating roller 21, which is provided inside the pressure roller 16 and rotatably connected thereto, and a circular tube 22 is provided at the internal axis of the built-in rotating roller 21, and a first slider 24 and a second slider 25 are slidably connected inside the circular tube 22, and a limiting groove 26 is provided on one side of the circular tube 22, and the second slider 25 extends to the outside of the circular tube 22 and is slidably connected to the limiting groove 26, and the first slider 24 does not contact the limiting groove 26 within its sliding stroke. A connecting rod 27 is fixedly connected between the first slider 24 and the second slider 25. An eccentric chamber 23 is provided on the other side of the circular tube 22. A slide 28 is slidably connected in the eccentric chamber 23. A plurality of second springs 29 are fixedly connected between the slide 28 and the eccentric chamber 23. A first cavity 32 is formed between the two first sliders 24 and the circular tube 22. A second cavity 33 is formed between the slide 28 and the outer surface of the circular tube 22. The first cavity 32 and the second cavity 33 are connected by a connecting pipe. The first cavity 32 and the second cavity 33 are filled with liquid. In this embodiment, specifically: the second slider 25 is internally threadedly connected to a second screw 31, the threads of the two second screws 31 are arranged in opposite directions, and the ends of the two second screws 31 close to each other are fixedly connected. A second motor 30 is fixedly connected to the inner wall of the built-in rotating drum 21, and the output shaft end of the second motor 30 is fixedly connected to the second screw 31. The two second sliders 25 are synchronously moved in opposite directions by the two second screws 31 with opposite threads, so that liquid is injected from the first cavity 32 to the second cavity 33, and the eccentric weight is adjusted, thereby realizing automatic adjustment of the downward pressure of the pressure roller 16; In this embodiment, specifically, a synchronous motor 34 is fixedly connected to the side of the two pressure rollers 16 that is away from each other. The output shaft end of the synchronous motor 34 extends into the pressure roller 16 and is fixedly connected to the built-in rotating drum 21. The two synchronous motors 34 achieve synchronous rotation of the built-in rotating drum 21 in the two pressure rollers 16. Under the above arrangement, the second motor 30 drives the first slider 24 to slide toward the center, injecting the liquid in the first cavity 32 into the second cavity 33, thereby adjusting the eccentric weight inside the pressure roller 16. Driven by the synchronous motor 34, the built-in rotating roller 21 rotates, driving the eccentric weight to continuously generate a large downward force on the tempered glass body 1. This downward force is much greater than the pressure generated by the weight of the pressure roller 16 alone, thereby amplifying the difference in the values measured by the two sets of pressure sensors 7 and the inclination sensor 35, as well as the sliding distance measured by the potentiometer, thereby amplifying the defect difference between the sample to be tested and the standard sample. In this embodiment, specifically, a plurality of pressure sensors 7 are provided in the rubber pad 6. The pressure sensors 7 on both sides are symmetrically distributed around the center of the tempered glass body 1, and the pressure sensors 7 on one side are equally distributed. The pressure sensors 7 are used to detect the pressure distribution values at both ends of the tempered glass body 1 after the pressure of the pressure roller 16 is applied. A detection method of a non-destructive tempered glass self-explosion hidden danger detection device, comprising: S1: Insert the tempered glass to be tested and the standard sample into the slot 5 respectively, so that the pressure roller 16 is in close contact with the upper surface of the tempered glass; S2: The second motor 30 drives the two first sliders 24 to move toward the center to adjust the amount of liquid in the second cavity 33. Then, the synchronous motor 34 drives the built-in rotating drum 21 to rotate. The different weights in the eccentric chamber 23 generate different downward pressures to meet the requirements of the pressure resistance test of the specified tempered glass. S3: The first motor 12 drives the movable crossbeam 11 to move leftward, and the pressure roller 16 slides laterally on the upper surface of the tempered glass body 1. If the potentiometer provided at the sliding position between the first round rod 19 and the second round rod 20 detects relative sliding, it means that the internal stress of the tempered glass to be tested is uneven compared with that of the standard sample. If the tilt sensor 35 detects a change in the angle, it means that there is a protrusion on the surface of the tempered glass to be tested. S4: After the pressure roller 16 slides one stroke, the pressure sensor 7 measures the pressure distribution values at both ends of the tempered glass to be tested and the standard sample. By comparing the pressure values of the pressure sensors 7 at corresponding points at the same position in the two groups and the pressure values of the pressure sensors 7 at symmetrical points on both sides of the same group, if there is a difference in the values, it means that the internal stress of the tempered glass to be tested is uneven.

The output shaft end of the synchronous motor (34) extends into the pressing roller (16) and is fixedly connected to the built-in rotating roller (21). The two synchronous motors (34) achieve synchronous rotation of the built-in rotating roller (21) in the two pressing rollers (16).
9. The non-destructive tempered glass self-explosion hazard detection device according to claim 8, characterized in that: A plurality of pressure sensors (7) are provided in the rubber pad (6), wherein the pressure sensors (7) on both sides are symmetrically distributed based on the center of the tempered glass body (1), and the pressure sensors (7) on one side are equally distributed, and are used to detect the pressure distribution values at both ends of the tempered glass body (1) after the pressure is applied by the pressure roller (16).
10. The detection method of the non-destructive tempered glass self-explosion hidden danger detection device according to claim 9, characterized in that: include: S1: inserting the tempered glass to be tested and the standard sample into the slot (5) respectively, so that the pressure roller (16) is in close contact with the upper surface of the tempered glass; S2: The second motor (30) drives the two first sliders (24) to move toward the center, adjusts the amount of liquid in the second cavity (33), and then drives the built-in rotating roller (21) to rotate through the synchronous motor (34). The different weights in the eccentric chamber (23) generate different downward pressures to meet the requirements of the pressure resistance test of the specified tempered glass. S3: The first motor (12) drives the movable crossbeam (11) to move to the left, and the pressure roller (16) slides laterally on the upper surface of the tempered glass body (1). If the potentiometer provided at the sliding position of the first round rod (19) and the second round rod (20) detects relative sliding, it means that the internal stress of the tempered glass to be tested is uneven compared with the standard sample. If the inclination sensor (35) detects a change in angle, it means that there is a bulge on the surface of the tempered glass to be tested. S4: After the pressure roller (16) slides for one stroke, the pressure sensor (7) measures the pressure distribution values at both ends of the tempered glass to be tested and the standard sample. By comparing the pressure values of the pressure sensors (7) at the corresponding points at the same position of the two groups and the pressure values of the pressure sensors (7) at the symmetrical points on both sides of the same group, if there is a difference in the values, it means that the internal stress of the tempered glass to be tested is uneven.
