[0002] In the production and quality inspection of tempered glass, compressive testing of glass is an important means to evaluate the strength and safety performance of glass. In the prior art, the common compressive testing method is to place the glass sample to be tested in a special testing device and gradually pressurize it until the glass breaks, thereby evaluating its compressive limit. However, since glass is brittle when subjected to external forces, a large number of fragments will be generated during its breaking process, and these fragments often scatter at high speed and scatter in the testing device and the surrounding area.

DETAILED DESCRIPTION

[0020] The above and other technical features and advantages of the present invention are described in more detail below in conjunction with the accompanying drawings.

[0021] This embodiment provides a technical solution: Figures 1 to 9 As shown, a compression resistance testing device for tempered glass production includes a bottom plate 1, a pressurizing mechanism, an electric slide mechanism, a liquid covering mechanism 4, a clamping mechanism 6, a heating mechanism 7 and a material rack mechanism 3. A load-bearing platform 11 is provided in the middle of the upper surface of the bottom plate 1, and the load-bearing platform 11 is used to place glass 100.

[0022] The glass 100 is transported and placed on a pallet 9, which includes an iron plate 91. A frame-shaped block 93 is provided on the upper surface of the iron plate 91. Two grooves 92 are provided on both sides of the iron plate 91. The sizes of the iron plate 91 and the frame-shaped block 93 can be set according to the size of the glass 100 to be tested, wherein the frame-shaped block 93 is slightly larger than the width of the glass 100, specifically 1-3 cm larger.

[0023] The pressurizing mechanism is installed on the upper surface of the base plate 1, and can be located in the middle part of the base plate 1. The pressurizing mechanism corresponds vertically to the load-bearing platform 11, and is used to apply pressure to the glass 100; the pressurizing mechanism includes a hydraulic cylinder 52 fixed to the upper surface of the base plate 1 through a support frame 51, and the output end of the hydraulic cylinder 52 is set downward, and the telescopic end of the hydraulic cylinder 52 is successively installed with a pressure detector 53 and a pressure head 54, and the pressure head 54 corresponds vertically to the load-bearing platform 11.

[0024] Since the non-Newtonian liquid may adhere to the surface of the pressure head 54, a cleaning piece for cleaning the non-Newtonian liquid on the pressure head 54 is provided at the bottom of the pressure head 54; the cleaning piece includes a first motor 551 embedded in the bottom of the pressure head 54 and a transverse groove 554 opened at the bottom of the pressure head 54, a telescopic rod 552 is installed at the output end of the first motor 551, an L-shaped block 555 is fixed at the lower end of the telescopic rod 552, the L-shaped block 555 has a transverse portion and a vertical portion fixed to the outer end of the transverse portion, and the outer side of the telescopic rod 552 is sleeved with a first Spring 553, when the L-shaped block 555 moves downward under the action of the first spring 553, the lateral portion of the L-shaped block 555 will be separated from the lateral groove 554. At this time, the L-shaped block 555 fits the outer contour of the pressure head 54. When the first motor 551 is running, the rotating cleaning part can scrape the surface of the pressure head 54 to remove the non-Newtonian liquid that may adhere to the surface of the pressure head 54; when the pressure head 54 is pressed down, the lateral portion of the L-shaped block 555 will enter the lateral groove 554, and the inner lateral groove 554 is adapted to the lateral portion of the L-shaped block 555.

[0025] The electric slide mechanism is installed on the upper surface of the base plate 1, and its moving end moves along the length direction of the base plate 1; the electric slide mechanism includes two vertical plates fixed on the upper surface of the base plate 1, a first optical axis 21 and a one-way screw 22 are rotatably installed between the two vertical plates, a second motor 23 that drives the one-way screw 22 to rotate is fixed on one of the vertical plates, a moving frame 24 is slidably arranged on the first optical axis 21, and the moving frame 24 is threadedly connected to the one-way screw 22, when the second motor 23 is operated, the moving frame 24 can be driven to move laterally, the moving frame 24 is the moving end of the electric slide mechanism, the moving frame 24 includes a sliding sleeve slidably arranged on the first optical axis 21 and a threaded sleeve threadedly connected to the one-way screw 22, and the threaded sleeve and the sliding sleeve are fixed by a connecting plate.

[0026] The liquid covering mechanism 4 is installed on one side of the moving end of the electric slide mechanism, and is used to coat a layer of non-Newtonian liquid on the surface of the glass 100 to prevent the glass 100 from splashing around when it is broken; the liquid covering mechanism 4 includes a liquid storage tank 41 and a horizontal round rod 44 fixed to the moving end of the electric slide mechanism, the non-Newtonian liquid is stored in the liquid storage tank 41, a rotating drum 45 is rotatably installed on the horizontal round rod 44, a flat material nozzle 43 is fixed on the rotating drum 45, the flat material nozzle 43 is driven to rotate by the first driving member to adjust the angle of the flat material nozzle 43, a pump body 42 is installed on the liquid storage tank 41, and the discharge end of the pump body 42 is connected to the flat material nozzle 43 through a hose.

[0027] When in use, the angle of the flat material nozzle 43 is adjusted by the first driving member, and the flat material nozzle 43 is tilted downward, and the discharge end of the flat material nozzle 43 is close to the surface of the glass 100. The non-Newtonian liquid in the liquid storage tank 41 can be drawn out through the pump body 42 and finally discharged through the flat material nozzle 43. The width of the discharge end of the flat material nozzle 43 is greater than the width of the glass 100. When the electric slide mechanism drives the liquid covering mechanism 4 to move, the discharged non-Newtonian liquid will fully cover the glass 100 (including the four sides of the glass 100).

[0028] The first driving member includes an electric push rod 463 fixed to the moving end of the electric slide mechanism, a rack 462 is fixed to the telescopic end of the electric push rod 463, and a first gear 461 meshingly connected with the rack 462 is fixed to the rotating drum 45. When the telescopic end of the electric push rod 463 is extended and retracted, the rack 462 can be driven to move horizontally, and then cooperate with the first gear 461 to drive the rotating drum 45 and the flat material nozzle 43 to flip with the horizontal round rod 44, so as to adjust the angle of the flat material nozzle 43.

[0029] Non-Newtonian liquids are liquids whose flow behavior does not completely follow Newton's laws, that is, their viscosity is no longer a constant value, but will change significantly with factors such as applied shear stress or shear rate, time, temperature, etc.

[0030] In this embodiment, the non-Newtonian liquid 1 can be formed by mixing polyethylene glycol with nano-scale silica particles, wherein the polyethylene glycol is selected from low molecular weight PEG, such as PEG 400 or PEG 600. Low molecular weight PEG has a lower viscosity at room temperature, which is convenient for liquid transportation, coating and recycling; at the same time, the viscosity of PEG is sensitive to temperature, and the fluidity under low shear state can be optimized by temperature regulation. In addition, the nano-scale silica particles are selected from fumed silica or other forms of nano-silicon dioxide with a particle size between 10 and 50 nanometers. Because after the nano-silicon dioxide is dispersed in PEG, the fluidity of the system can be maintained at low shear, and when subjected to high-speed impact, an instantaneous network structure is quickly formed between the particles, which significantly improves the viscosity of the system and achieves a shear thickening effect, thereby effectively capturing and adhering glass fragments.

[0031] In order to ensure that the non-Newtonian liquid can respond quickly and effectively capture the broken glass 100 when it breaks, and at the same time maintain good fluidity and easy recycling characteristics under normal conditions, it is necessary to design and optimize multiple rheological and physicochemical parameters of the non-Newtonian liquid. The following are some key parameters and their reference descriptions: 1. Low shear viscosity: Significance: Under low shear conditions such as coating, conveying and recycling processes, non-Newtonian liquids need to be fluid enough to evenly cover the glass surface and be easy to pump when not subjected to external forces.

[0032] Setting range: Generally, it can be controlled at about 5-10 mPa·s. The specific value depends on the liquid matrix and formula.

[0033] 2. High shear viscosity: Significance: When glass breaks and generates high-speed impact and high shear rate, the liquid should thicken rapidly to form a solid-like protective barrier to capture the glass fragments.

[0034] Setting range: Under high shear conditions, the viscosity may need to reach thousands or even tens of thousands of mPa·s. The specific value needs to be determined experimentally to ensure that it can effectively block and adhere to high-speed debris.

[0035] 3. Critical shear rate: Significance: This point is the transition point where non-Newtonian liquid changes from a low viscosity state to a high viscosity state. This value needs to match the local shear rate generated when the glass breaks in the actual test to ensure that the shear thickening effect can be triggered at the moment of impact.

[0036] Setting reference: Usually in The specific value within the range is determined based on the impact test data.

[0037] 4. Shear thickening ratio: Significance: Indicates the increase in viscosity of a liquid at a high shear rate compared to its viscosity at a low shear rate. The higher the thickening ratio, the more effective the liquid is at protecting it from impact.

[0038] Target value: Generally, a thickening ratio of 100 times or higher is desired to ensure that an effective barrier is quickly formed when broken.

[0039] 5. Recovery time: Significance: After the impact stops, the liquid should be able to quickly return to a low viscosity state for easy recovery and reuse.

[0040] Setting requirements: The recovery time should generally be controlled within a few seconds so that the system can be recycled quickly.

[0041] 6. Yield stress, if applicable: Significance: For non-Newtonian liquids with Bingham plastic behavior, the yield stress determines the minimum stress value at which the liquid begins to flow.

[0042] Setting requirements: The yield stress should not be too high, otherwise it may affect the fluidity under low shear conditions; generally, the formula is adjusted to ensure that it can meet the coating requirements and quickly trigger thickening when impacted.

[0043] 7. Temperature sensitivity: Significance: Non-Newtonian liquids such as PEG-based systems are often sensitive to temperature changes. Temperature regulation can help adjust their viscosity under low shear and high shear conditions.

[0044] Setting requirements: The viscosity curve of the liquid within the operating temperature range, such as room temperature to slightly higher temperature, should be determined to ensure that the viscosity is moderate at normal operating temperature and can respond quickly when impacted; the temperature coefficient such as d(log(η)) / dT can be used as a reference indicator.

[0045] 8. Density and stability: Significance: The density of the fluid affects the interaction between the liquid and the glass fragments. At the same time, various parameters need to be kept stable during long-term cyclic use.

[0046] Setting requirements: The density should be moderate and should not be too large to affect the overall weight of the system; at the same time, it is necessary to add dispersants and stabilizers to ensure that there is no particle sedimentation or formula changes in the long term.

[0047] The clamping mechanism 6 is installed on the other side of the moving end of the electric slide mechanism, and is used to remove the inspected glass 100 from the load-bearing platform 11 to realize automated operation; the clamping mechanism 6 includes two mounting plates fixed to the lower side of the moving end of the electric slide mechanism, a second optical axis 63 and a bidirectional screw rod 62 are rotatably installed between the two mounting plates, one of the mounting plates is fixed with a third motor 61 for driving the bidirectional screw rod 62 to rotate, two symmetrically arranged moving plates 64 are threadedly connected to the bidirectional screw rod 62, and the two moving plates 64 are slidably connected to the second optical axis 63, a first latch 65 and a second latch 66 are fixed on the inner sides of the two moving plates 64, and the length of the first latch 65 is greater than the length of the second latch 66.

[0048] When the third motor 61 is running, the two movable plates 64 will move closer to or away from each other. After the two movable plates 64 move closer to each other, the first latch 65 and the second latch 66 are respectively inserted into the corresponding grooves 92 to move the tray 9. When the two movable plates 64 move away from each other, since the length of the first latch 65 is greater than the length of the second latch 66, the second latch 66 will be the first to disengage from the corresponding groove 92, so that the tray 9 is flipped downward with the first latch 65 as the base point.

[0049] Since the liquid covering mechanism 4 and the clamping mechanism 6 are respectively located on both sides of the moving end of the electric slide mechanism, there is a vacant portion in the middle of the moving end of the electric slide mechanism to facilitate the operation of the pressurizing mechanism.

[0050] The heating mechanism 7 is located on a side away from the liquid covering mechanism 4, and is used to heat the non-Newtonian liquid adhered to the broken glass 100, so as to realize the rapid separation of the non-Newtonian liquid from the broken glass 100; the heating mechanism 7 includes a heating plate 71 rotatably mounted on the upper surface of the bottom plate 1 through a mounting seat, and a second spring 73 is mounted on the lower side of the heating plate 71, and the lower side of the second spring 73 is connected to the bottom plate 1 through a bottom frame 72, so that the heating plate 71 can be supported by the second spring 73 to keep the water In a flat state, both outer sides of the base frame 72 are provided with vertical plates 75 fixed to the bottom plate 1, and a slide rod 76 is slidably provided on the vertical plate 75. A pulling plate 77 is fixed to the inner end of the slide rod 76, and the upper end of the pulling plate 77 corresponds horizontally to the movable plate 64. A pulling rope 74 is fixed to the lower surface of the heating plate 71, and the pulling rope 74 passes through the base frame 72 and is connected to the pulling plate 77. A rectangular through hole is opened on the bottom plate 1, and a collecting box 8 is arranged on the lower side of the rectangular through hole. The collecting box 8 has a liquid storage cavity and a glass storage cavity.

[0051] When the tray 9 moves to the upper side of the heating plate 71, the two moving plates 64 are moved outward by running the third motor 61, and the two second latches 66 will be separated from the corresponding grooves 92. At this time, the two moving plates 64 are respectively in contact with the two pulling plates 77. When the movement continues, the two pulling plates 77 will be pushed outward. Under the pulling of the pull rope 74, the heating plate 71 will gradually tilt and compress the second spring 73, and the tray 9 will also turn downward with the first latch 65 as the base point, and the glass 100 tray 9 will also turn downward synchronously until it tilts to a certain angle (it should be noted that the angle should not be tilted too downward to prevent glass fragments from falling into the liquid storage chamber. If necessary, A grid is provided on the glass storage cavity to catch the glass fragments that may fall), the heating plate 71 is heated to accelerate the flow of the non-Newtonian liquid adhering to the broken glass 100, and the non-Newtonian liquid flows into the liquid storage cavity of the collection box 8 for storage; then the third motor 61 is reversed, the heating plate 71 and the tray 9 are restored to a horizontal state under the action of the second spring 73, and the second latch 66 is inserted into the corresponding groove 92 again, and the tray 9 can be moved to the top of the glass storage cavity by the electric slide mechanism, and the same process as above is adopted to make the tray 9 unilaterally lifted, so that the glass fragments fall into the glass storage cavity, and the operator needs to take away the tray 9 at this time.

[0052] The material rack mechanism 3 is arranged so as to store two glasses 100 to be inspected. The material rack mechanism 3 is arranged at the moving end of the electric slide mechanism. The material rack mechanism 3 includes four rotating shafts 31 rotatably mounted on the moving end of the electric slide mechanism, and the four rotating shafts 31 are arranged in a rectangular shape. A lower support plate 32 is fixed at the lower end of the four rotating shafts 31, and two ends of the lower support plate 32 are respectively located on both sides of the rotating shaft 31. An upper support plate 33 is fixed on the rotating shaft 31. The upper support plate 33 vertically corresponds to one end of the lower support plate 32, and the width of the upper support plate 33 is greater than the width of the lower support plate 32. The four upper support plates 33 are all facing inwards. Pulleys 34 are fixed on the four rotating shafts 31, and the four pulleys 34 are connected through belts 35 for transmission. A second driving member for driving the rotating shaft 31 to rotate is arranged on the moving end of the electric slide mechanism. The second driving member includes a fourth motor 361 fixed to the moving end of the electric slide mechanism through a bracket. A second gear 362 is fixed to the output end of the fourth motor 361, and a third gear 363 meshingly connected with the second gear 362 is fixed on the corresponding rotating shaft 31.

[0053] When the fourth motor 361 is running, the four rotating shafts 31 are rotated through the cooperation of the second gear 362, the third gear 363, the pulley 34 and the belt 35 until the four lower support plates 32 rotate to 180°, and the four lower support plates 32 can no longer support the tray 9 of the next layer, and the tray 9 of the next layer will fall onto the load-bearing platform 11. Since the width of the upper support plate 33 is greater than the width of the lower support plate 32, the upper support plate 33 can still support the tray 9 of the previous layer. As the rotating shaft 31 continues to rotate, the other side of the lower support plate 32 will rotate to the inner side of the rotating shaft 31. At this time, the upper support plate 33 can no longer support the tray 9 of the previous layer, and the tray 9 of the previous layer will fall onto the four lower support plates 32, and the other sides of the four lower support plates 32 support it. When the next glass 100 is inspected, the lower support plate 32 is rotated until it can no longer support the tray 9 and can fall onto the load-bearing platform 11.

[0054] A method for detecting a compressive performance detection device for tempered glass production, comprising the following steps: Step 1: Storing the glass 100: placing two trays 9 on the four upper support plates 33 and the four lower support plates 32 of the rack mechanism 3, and placing the glass 100 on the trays 9; Step 2: Place the glass 100 on the load-bearing platform 11: Move the rack mechanism 3 to the load-bearing platform 11 through the electric slide mechanism, and operate the fourth motor 361 to drive the four shafts 31 to rotate. When one side of the four lower support plates 32 rotates and no longer contacts the glass 100, the next layer of glass 100 will fall freely onto the glass 100, and the upper layer of glass 100 will fall onto the lower support plate 32; Step 3: coating a non-Newtonian liquid: coating a layer of non-Newtonian liquid on the surface of the glass 100 by means of the liquid coating mechanism 4; Step 4, pressurizing: pressurizing the glass 100 by a pressurizing mechanism until the glass 100 breaks, the non-Newtonian liquid on the surface of the glass 100 will prevent the glass 100 from splashing, and the pressurizing mechanism records the maximum bearing pressure value of the glass 100; Step 5: Cleaning: Move the clamping mechanism 6 onto the load-bearing platform 11 through the electric slide mechanism, and clamp the tray 9 and move it away from the load-bearing platform 11 through the clamping mechanism 6.

[0055] In this embodiment, the non-Newtonian liquid can prevent the glass 100 fragments from being splashed mainly due to its unique shear thickening effect and dynamic response characteristics, and the specific reasons are as follows: 1. Shear thickening effect: Under low shear conditions, the non-Newtonian liquid exhibits a low viscosity state, which makes it easy to evenly coat the glass surface. However, once the glass breaks and produces a high-speed impact, the local shear rate increases sharply, and the liquid will quickly undergo shear thickening, and its viscosity will increase sharply, similar to the instantaneous transition from a fluid state to a semi-solid state. This rapid thickening allows the liquid to form a solid barrier that quickly absorbs and disperses the impact energy, thereby effectively preventing glass fragments from splashing at high speed.

[0056] 2. Energy absorption and dispersion: When glass breaks, the movement of the fragments carries high kinetic energy. Non-Newtonian liquids have a high damping effect after shear thickening, which can convert part of the kinetic energy of the glass fragments into deformation energy and friction energy inside the liquid, and quickly disperse the energy inside the liquid, thereby reducing the possibility of the fragments continuing to accelerate and reducing the splash range.

[0057] 3. Adhesion capture effect: Non-Newtonian liquids not only increase viscosity under high shear conditions, but also have strong adhesion. This adhesion allows the glass fragments to maintain a certain degree of adhesion with the liquid after breaking, preventing the fragments from quickly detaching from the liquid coating, thereby effectively limiting the scattering and dispersion of the fragments.

[0058] 4. Fast dynamic response: This type of non-Newtonian liquid usually responds to changes in external shear stress in a very short time (milliseconds), and can "activate" the shear thickening effect in time when the glass breaks, forming a protective barrier. This rapid dynamic response ensures that when an instantaneous impact comes, the liquid can play a protective role in time to avoid fragments from splashing.

[0059] The above description is only a preferred embodiment of the present invention, which is only illustrative and not restrictive of the present invention. Those skilled in the art understand that many changes, modifications, and even equivalences may be made to the present invention within the spirit and scope defined by the claims of the present invention, but all of them will fall within the scope of protection of the present invention.
