Description

Technical Field

[0001] The present invention relates to the technical field of glass testing, and in particular to a puncture resistance testing device for the research and development of laminated glass. Background Art

[0002] As an important safety protection material, laminated glass is widely used in areas with high safety requirements, such as automobile windshields, rail transit windows, building curtain walls and skylights, due to its excellent impact resistance and the ability to maintain integrity after breaking. In these application scenarios, laminated glass often needs to withstand high-speed impact or puncture loads from external objects, such as flying stone impacts during vehicle driving, head impacts in pedestrian collisions, or falling objects that may occur in building environments. To ensure its safety and reliability under actual working conditions, puncture resistance testing has become a key link in product research and development and quality control. The current common testing method is: first, place the glass on a rigid table, then fix the edge of the glass with a clamp, and then let an impact head fall vertically from a certain height to hit the glass surface. Subsequently, observe whether the glass is penetrated or cracked to determine its puncture resistance.

[0003] However, with the increasing complexity of modern architectural and transportation designs, curved and curved laminated glass is increasingly being used in applications such as car side windows, building domes, and streamlined high-speed rail fronts. This type of non-planar glass places higher demands on detection equipment, and existing detection devices have exposed significant technical defects when applied to curved glass: First, in real working conditions, the impact on glass is often not in an ideal vertical direction. For example, during vehicle movement, the impact of pedestrian heads, flying rocks, debris, and other objects usually manifests as oblique high-speed impacts. This type of oblique impact not only changes the direction of force decomposition, but may also cause more complex stress distribution and failure modes, and its failure mechanism is significantly different from that of vertical impact. There are significant differences. Since traditional laminated glass puncture resistance testing devices generally adopt a vertical free-fall structure, the impact angle of the impact head cannot be adjusted, making it difficult to simulate the common oblique impact conditions in real environments. As a result, the test results lack comprehensiveness and authenticity, limiting the accurate assessment of the safety performance of laminated glass under complex usage conditions. Secondly, the existing clamping system lacks adaptive adjustment capabilities and cannot match arc edges with different curvature radii, resulting in poor fit between the clamp and the glass contact surface, uneven distribution of clamping force, and loose clamping that can easily cause the glass to slip, warp or overall displacement at the moment of impact, which is especially significant when simulating oblique impacts, seriously affecting the precise positioning of the puncture point and the consistency of the force state. Summary of the Invention

[0004] In view of this, the present invention provides a puncture resistance testing device for laminated glass research and development, which can solve the shortcomings of existing testing devices that are difficult to simulate the common oblique impact conditions in real environments when applied to curved glass, resulting in a lack of comprehensiveness and authenticity in the test results.

[0039] See Figure 14 and Figure 15As shown, the lifting mechanism includes a connecting frame 1501, a movable plate 1502, a second spring 1503, a tooth plate 1504, a first rotating shaft 1505, a first gear 1506 and a second motor 1507; the supporting plate 13 is provided with a connecting frame 1501 on both the front and rear sides, and the movable plates 1502 are slidably arranged in the two connecting frames 1501; the two groups of support rods 14 on the top of the same supporting plate 13 are respectively slidably connected to the two movable plates 1502, and the space between the lower side of the support rod 14 and the bottom of the movable plate 1502 is slidably connected. A second spring 1503 is connected; the bottom of the two movable plates 1502 are connected to a tooth plate 1504, and the tooth plate 1504 slides through the bottom of the connecting frame 1501; a first rotating shaft 1505 is rotatably provided on the lower side of the support plate 13; two first gears 1506 are provided on the first rotating shaft 1505, and the two first gears 1506 are respectively engaged with the two tooth plates 1504; a second motor 1507 is installed on the lower front part of the support plate 13, and the output shaft of the second motor 1507 is connected to the front end of the first rotating shaft 1505.

[0040] See Figure 16-Figure 18 As shown, the telescopic mechanism includes a second rotating shaft 1901, a second transmission member 1902, a second gear 1903, a first tooth block 1904 and a third spring 1905; the second rotating shaft 1901 is rotatably arranged on the upper side of the support plate 13; the second transmission member 1902 includes a synchronous wheel and a synchronous belt, a synchronous wheel is arranged in the middle of the first rotating shaft 1505 and the middle of the second rotating shaft 1901, a synchronous belt is wound between the two synchronous wheels, and the first rotating shaft 1505 and the second rotating shaft 1901 are transmitted through the synchronous wheel and the synchronous belt; four second gears 1903 are connected to the second rotating shaft 1901 at intervals; first tooth blocks 1904 are evenly spaced on the outside of the movable tube 17, and the first tooth block 1904 is engaged with the second gear 1903; a third spring 1905 is connected between the inner side of the movable tube 17 and the limit rod 18.

[0041] In the initial state, the supporting rod 704 presses against the touch plate 701, so that the touch plate 701 limits the connecting rod structure of the clamping rod frame 702, thereby making the first spring 703 in a stretched state; When in use, first pull the door of the cabinet 1 to rotate and open it, then use the electric slide rail 12 to drive the two support plates 13 to move simultaneously, so as to adjust the distance between the two support plates 13 so that the curved glass can be placed between the tops of the two support plates 13. After adjustment, the curved glass is placed between the tops of the two support plates 13 (the area to be tested of the curved glass faces upward), so that the support rod 14 is located on the inner side of the curved glass and the limit rod 18 is located on the outer side of the curved glass, and then the second motor 1507 drives the first rotating shaft 1505 to rotate. The first gear 1506 rotates clockwise, thereby driving the first gear 1506 to rotate clockwise, so that the first gear 1506 drives the tooth plate 1504 and the movable plate 1502 to move upward, so that the movable plate 1502 drives the support rod 14 to move upward through the second spring 1503. At the same time, when the first rotating shaft 1505 rotates clockwise, the first rotating shaft 1505 drives the second rotating shaft 1901 and the second gear 1903 to rotate clockwise through the second transmission member 1902, so that the second gear 1903 drives the movable tube 17 through the first tooth block 1904. The movable tube 17 extends from the inside of the curved tube 16, so that the movable tube 17 drives the limiting rod 18 to move to the side close to the curved glass through the third spring 1905. When the support rod 14 contacts the inner surface of the curved glass, the inner surface of the curved glass will press against the support rod 14, causing the support rod 14 to stop moving upward. Then, as the movable plate 1502 continues to move upward, the second spring 1503 stretches, and the second spring 1503 exerts an upward force on the support rod 14 through deformation, causing the support rod 14 to support the inner surface of the curved glass. When the limiting rod 18 contacts the curved glass, the inner surface of the curved glass will press against the support rod 14, causing the support rod 14 to stop moving upward. When the outer surface of the glass contacts the curved glass, the outer surface of the curved glass will press against the limiting rod 18, causing the limiting rod 18 to stop moving. Then, as the movable tube 17 continues to extend from the curved tube 16, the third spring 1905 is compressed. The third spring 1905 exerts pressure on the limiting rod 18 through deformation, causing the limiting rod 18 to press against the outer surface of the curved glass. In this way, the support rod 14 and the limiting rod 18 exert pressure on the inner and outer surfaces of the curved glass, allowing the support rod 14 and the limiting rod 18 to clamp the end area of ​​the curved glass, thereby limiting the curved glass. Then, the subsequent steps are carried out according to the needs. If the curved glass needs to be punctured in the vertical direction, no additional operation is required; if the curved glass needs to be punctured in the oblique direction, the first motor 1001 is used to drive the screw rod 1002 to rotate through the first transmission member 1003, so that the screw rod 1002 drives the sleeve 1004 to move to the left, so that the sleeve 1004 squeezes the support frame 9 through the connecting plate 1005 to rotate counterclockwise, thereby driving the electric slide rail 12, the support plate 13 and the curved glass to rotate counterclockwise, so as to adjust the inclination of the support frame 9, the electric slide rail 12 and the support plate 13, and then adjust the arc The direction of the glass is adjusted until the surface of the curved glass forms a certain angle with the motion trajectory of the first impact head 6. During this period, when the support frame 9 rotates counterclockwise, the support frame 9 drives the slide plate 1102 to slide on the movable block 1101, so that the slide plate 1102 drives the movable block 1101 to rotate, so that the movable block 1101 adapts to the posture change of the slide plate 1102. When the direction of the curved glass is adjusted, the brake caliper 1103 brakes the slide plate 1102 to limit the sliding of the slide plate 1102, and then the slide plate 1102 limits the support frame 9 to ensure that the inclination angle of the support frame 9 is stable; After that, the cabinet door of the cabinet body 1 is pushed to reverse and close, and then the steel cable is unwound by the winch 4, so that the steel cable releases the sliding frame 3, so that the sliding frame 3, the first guide rail 5, the first impact head 6 and the touch plate 701 fall downward under gravity, and then the first impact head 6 hits the surface of the curved glass, thereby performing a puncture test on the curved glass. During this period, when the touch plate 701 moves downward and separates from the support rod 704, the first spring 703 returns to its original state, and the first spring 703 drives the card rod frame 702 to move downward, so that the card rod frame 702 is stuck in the groove of the first impact head 6, thereby locking the first impact head 6 to prevent the first impact head 6 from detaching from the first guide rail 5. At the same time, the downward movement of the card rod frame 702 will drive the touch plate 701 to rotate through the connecting rod structure. After the first impact head 6 completes the collision with the curved glass, the winch 4 is used to reel in the steel cable, so that the steel cable pulls the sliding frame 3 upward, thereby driving the first guide rail 5, the first impact head 6 and the touch plate 701 to move upward and reset. When the touch plate 701 moves upward until it contacts the push rod 704, the push rod 704 will squeeze the touch plate 701 to reverse and reset, so that the touch plate 701 drives the clamping frame 702 to move upward and reset through the connecting rod structure. The first spring 703 is stretched, so that the clamping frame 702 leaves the groove of the first impact head 6, thereby unlocking the first impact head 6. In this way, the puncture test of the curved glass can be completed. During this period, the puncture test of the curved glass can be continuously viewed through the camera 8, and the test result can be obtained based on the appearance of the curved glass. After the test of the curved glass is completed, the operation is performed according to the state of the support frame 9. If the support frame 9 does not tilt, no additional operation is required. If the support frame 9 tilts, the brake caliper 1103 is used to release the brake on the slide 1102, so that the slide 1102 releases the limit of the support frame 9. Then, the first motor 1001 is used to drive the screw rod 1002 to reverse through the first transmission member 1003, so that the screw rod 1002 drives the sleeve 1004 to move to the right and reset, so that the sleeve 1004 pulls the support frame 9 through the connecting plate 1005 to rotate clockwise and reset, thereby driving the electric slide rail 12, the support plate 13 and the curved glass to rotate clockwise and reset. During this period, when the support frame 9 rotates clockwise and resets, the support frame 9 will drive the slide 1102 to slide and reset on the movable block 1101, so that the slide 1102 drives the movable block 1101 to reverse and reset; After the support frame 9 is restored to its state, the cabinet door of the cabinet body 1 is pulled again to rotate and open, and then the first shaft 1505 is driven by the second motor 1507 to rotate counterclockwise, thereby driving the first gear 1506 to rotate counterclockwise, so that the first gear 1506 drives the tooth plate 1504 and the movable plate 1502 to move downward and reset. During this period, the second spring 1503 gradually returns to its original state. At the same time, when the first shaft 1505 rotates counterclockwise, the first shaft 1505 will drive the second shaft 1901 and the second gear 1903 to rotate counterclockwise through the second transmission member 1902, so that the second gear 1903 drives the movable tube 17 to retract into the arc tube 16 through the first tooth block 1904, thereby The third spring 1905 gradually returns to its original state. When the second spring 1503 returns to its original state, the movable plate 1502 will drive the support rod 14 to move downward and reset through the second spring 1503, so that the support rod 14 is separated from the inner surface of the curved glass. When the third spring 1905 returns to its original state, the movable tube 17 will drive the limit rod 18 to move to the side away from the curved glass and reset through the third spring 1905, so that the limit rod 18 is separated from the outer surface of the curved glass, thereby releasing the end area of ​​the curved glass by the support rod 14 and the limit rod 18, and then releasing the limit of the curved glass. After that, the curved glass that has completed the test is taken out from between the tops of the two support plates 13, and then the cabinet door of the cabinet body 1 is pushed to reverse and close.

[0042] See Figure 13 As shown, a guide rod 20 is also included; the guide rod 20 is symmetrically arranged on the top of the support plate 13, and the guide rod 20 is used to guide the curved glass.

[0043] By providing the guide rod 20 , the operator can place the curved glass by using the guidance of the guide rod 20 , thereby facilitating the operator's placement of the curved glass.

[0044] See Figure 6-Figure 8As shown, a replacement mechanism is also included, which includes a fixed frame 21, a rotating frame 22, a second guide rail 23, a third motor 24, a third gear 25, a second gear block 26 and a second impact head 27; a fixed frame 21 is installed on the upper front side of the cabinet 1; a rotating frame 22 is rotatably provided inside the fixed frame 21, and a second guide rail 23 is rotatably provided on the upper side of the rotating frame 22, the second guide rail 23 is arc-shaped, and the second guide rail 23 contacts the first guide rail 5, and the second guide rail 23 and the first guide rail 5 form a ring guide by contact; the front side of the fixed frame 21 is installed There is a third motor 24; a third gear 25 is connected to the output shaft of the third motor 24; second tooth blocks 26 are evenly spaced on the inner side of the rotating frame 22, and the third gear 25 is engaged with the second tooth block 26; second impact heads 27 are slidingly arranged at intervals on the second guide rail 23, and the types of second impact heads 27 are different, so that different second impact heads 27 can be replaced before testing to test the curved glass. A card slot is also provided on the top of the second impact head 27, which is convenient for locking the second impact head 27 by using the card rod frame 702 to be inserted into the card slot after replacement.

[0045] By setting up a replacement mechanism, when the first impact head 6 needs to be replaced, the third motor 24 can be used to drive the third gear 25 to rotate, so that the third gear 25 drives the rotating frame 22 to rotate through the second tooth block 26, so that the rotating frame 22 pushes the first impact head 6 and the second impact head 27 to slide on the annular guide rail formed by the first guide rail 5 and the second guide rail 23, so as to adjust the position of the first impact head 6 and the second impact head 27 until the required second impact head 27 completely enters the first guide rail 5. In this way, when the sliding frame 3 and the first guide rail 5 fall downward due to gravity, the first guide rail 5 can drive the required second impact head 27 to fall downward, so that the required second impact head 27 can perform a puncture test on the curved glass, thereby facilitating the operator to use different second impact heads 27 to test the curved glass.
