Description

Technical Field

[0001] This application relates to the field of glass performance testing, and in particular to a testing fixture for fire-resistant glass performance in the production of fire-resistant doors and windows. Background Technology

[0002] Currently, fire-resistant glass is one of the components of fire-resistant doors and windows. Before being put into use, fire-resistant glass needs to undergo fire performance testing. At present, people use fire-resistant glass performance testing equipment in the production of fire-resistant doors and windows to test the fire performance of fire-resistant glass.

[0003] In related technologies, a fire-resistant glass performance testing fixture for fireproof door and window production is disclosed. This fixture consists of a top component, a hollow frame, and a gas stove. The hollow frame is connected to the center of the upper surface of the gas stove, and the top component is positioned directly above it. The top component includes a lower opening groove plate and a U-shaped plate. The lower opening groove plate is connected to the center of the inner front surface of the U-shaped plate, and rectangular grooves are symmetrically formed on the left and right inner sidewalls of the U-shaped plate. This design allows the fire-resistant glass to be completely concealed within the space formed by the top component, the hollow frame, and the gas stove when operating the device. This enables fire resistance performance testing of the fire-resistant glass while it is completely concealed, preventing fire exposure and reducing the damage to the work environment caused by fire. By designing a clamping assembly structure, clamping components are symmetrically arranged on the left and right sides inside the U-shaped plate. The clamping assembly includes a sliding plate and a U-shaped clamping plate. The sliding plate, connected to the middle of the outer surface of the U-shaped clamping plate, slides along the rectangular groove. A baffle is connected to the middle of the inner surface of the U-shaped clamping plate. This design allows the user to operate the clamping assembly in the device to automatically clamp the fireproof glass. This eliminates the need for people to manually clamp the fireproof glass and then put it into a fire for fire performance testing, thereby preventing fire damage to the human body and increasing the safety of the user when operating the device.

[0004] The aforementioned technologies have the following drawbacks: existing fire-resistant glass performance testing devices mostly adopt a single-function design, either only capable of fire-resistant heating testing or performing impact resistance testing separately, resulting in a fragmented testing process and low efficiency.

[0005] Meanwhile, the impact mechanisms of traditional testing devices mostly strike in a fixed direction, which cannot simulate the multi-directional stress scenarios that fireproof glass may be subjected to during actual fires or external impacts, resulting in insufficient comprehensiveness and authenticity of the test results. Summary of the Invention

[0006] In order to more comprehensively test the performance of fire-resistant glass, this application provides a fire-resistant glass performance testing fixture for the production of fire-resistant doors and windows.

[0011] Optionally, the side limiting component includes; The side U-shaped plates are two in number, and the two side U-shaped plates are positioned opposite each other directly above the bottom U-shaped plate, and are movably connected to the box body in the horizontal length direction of the bottom pressure plate; The side wall of the U-shaped groove of the side U-shaped plate is coplanar with the bottom of the U-shaped groove of the bottom U-shaped plate, and the other wall of the U-shaped groove of the side U-shaped plate is oriented towards the impact zone.

[0012] Optionally, the top edge limiting component includes; The lifting plate is provided in multiple manner, and the multiple lifting plates are evenly distributed along the horizontal length direction of the bottom edge pressure plate. The feeding door is slidably connected to the top of the box, and the lifting plate is installed on the feeding door in a liftable manner. A V-shaped groove is provided at the bottom end of the lifting plate. The V-shaped groove is composed of a first groove wall and a second groove wall that intersect at their top ends.

[0015] Optionally, the impact component includes; A magnetic plate is installed at the end of the guide rod away from the striking hammer; A pressure sensor is connected to the magnetic plate and the guide rod; An electromagnet is disposed on the side of the magnetic plate away from the guide rod, and is movably connected to the guide tube along the length of the guide rod.

[0016] In summary, this application includes at least one of the following beneficial technical effects: 1. The core benefit of the fire-resistant glass performance testing fixture for fireproof doors and windows produced in this application lies in its integrated testing of fire resistance and impact resistance, overcoming the shortcomings of traditional testing devices that are single-function and fragmented in their processes. The interior of the chamber is divided into a combustion zone and an impact zone, integrating the high-temperature fire resistance testing of the flame-spraying device with the multi-directional impact testing of the impact mechanism within the same chamber. Combined with the automated and precise fixing of the edge limiting mechanism and the automatic sorting and collection system for qualified products and waste, a fully automated testing solution is constructed, from feeding, limiting, dual-function testing to discharge sorting. This not only completely changes the inefficient mode of traditional devices that require separate equipment and steps to complete a single test, but also, by simulating the high-temperature and multi-directional impact composite scenarios in actual fire environments, makes the test results closer to real-world operating conditions.

[0017] 2. In this application, the edge limiting mechanism constructs a three-dimensional support and fixing structure for the fireproof glass through the precise coordination of the bottom edge limiting component, the side edge limiting component, and the top edge limiting component. After the fireproof glass falls vertically onto the discharge gate, the bottom of the U-shaped groove of the bottom edge limiting component provides a bottom bearing surface. The first cylinder drives the bottom edge pressure plate to move parallel, pressing the bottom edge of the glass tightly against the bottom of the groove, forming a stable bottom constraint. The side limiting assembly, driven by a motor-driven bidirectional lead screw, moves two side U-shaped plates synchronously closer to or further away along a slide rail. The side U-shaped plates' groove walls limit the vertical edge of the fireproof glass, while the bottom of the grooves of the two side U-shaped plates clamps the fireproof glass. Their coplanar design with the bottom of the bottom U-shaped plate ensures a flat surface for the glass under impact. The top limiting assembly controls the lifting plate's movement via a second telescopic component. The first groove wall of the V-shaped slot is coplanar with the bottom of the bottom U-shaped plate and the side U-shaped plate's groove wall on the side impact mechanism, collectively supporting the edge of the glass away from the impact mechanism. This ensures that the fireproof glass's edge receives comprehensive and effective support when impacted. The bottom, side, and top limiting assemblies form a closed-loop support, ensuring the fireproof glass's edges remain stable and unaffected by high temperatures and multi-directional impacts, preventing displacement or wobbling. Meanwhile, the spacing between the bottom edge pressure plate and the bottom edge U-shaped plate, the spacing between the two side U-shaped plates, and the height of the lifting plate can be freely adjusted, allowing the bottom edge limiting component, side limiting component, and top edge limiting component to work together to clamp rectangular fireproof glass of various sizes. In contrast, the impact mechanism of traditional testing devices is mostly a single impact at a fixed angle, which can only test the impact resistance of the glass at a single location and in a single direction. However, in actual fires, fireproof glass may face external forces from different directions and with different forces, making it difficult for the test results to reflect the actual usage conditions.

[0018] 3. In this application, after the fireproof glass is fixed by the edge limiting mechanism, the lifting cylinder drives the alignment plate to lift along the box wall, adjusts it to a preset height facing the glass, and completes the alignment of the striking hammer with the central part of the fireproof glass. Subsequently, through the coordinated expansion and contraction of multiple third telescopic members, the guide tube is pushed to drive the ball head to rotate in the ball socket, adjust the impact angle of the striking hammer, and adapt to the multi-directional test requirements. The fourth telescopic member extends to push the electromagnet towards the magnetic plate until the electromagnet can attract the magnetic plate. Then, the fourth telescopic member contracts to drive the guide rod to move towards the outside of the box. When the striking hammer abuts against the guide tube, the electromagnet instantaneously changes the current direction, turning the magnetic attraction force for adsorbing the magnetic plate into a magnetic repulsive force for repelling the magnetic plate. Under the action of the magnetic repulsive force, the guide rod drives the striking hammer to quickly move towards the fireproof glass to complete one impact. The pressure sensor monitors the magnitude of the impact force in real time. Then the electromagnet changes the current direction again. The fourth telescopic member extends again to push the electromagnet towards the magnetic plate until the electromagnet can attract the magnetic plate. Then, the fourth telescopic member contracts to drive the guide rod to move towards the outside of the box. When the striking hammer abuts against the guide tube, that is, when the striking hammer is reset, the striking hammer impacts the fireproof glass again. In this way, the striking hammer strikes a certain position of the fireproof glass multiple times. By judging the damage condition of the fireproof glass, the strength of this position of the fireproof glass can be detected. If the fireproof glass is not damaged, it means that the strength of the fireproof glass is qualified. If multiple or different-direction impacts are required, repeat the above angle adjustment and energy storage impact steps until all impact tests are completed. Among them, by adjusting the current intensity of the electromagnet, the magnitude of the electromagnetic repulsive force of the electromagnet can be controlled, and thus multi-angle and multi-strength impact tests on the fireproof glass can be achieved.

[0019] 4. In this application, after the test is completed, the edge limiting mechanism is released. The intact qualified glass falls into the discharge guide tube through the discharge door and is承接 by the receiving groove with a buffer elastic layer inside, avoiding damage during the falling process. Part of the broken glass fragments enter the first waste material tank through the discharge guide tube, and the other part slides along the inclined bottom of the box towards the waste residue door and falls into the second waste material tank. The whole process does not require manual intervention, realizing the automatic separation and collection of qualified fireproof glass and broken fireproof glass waste residue, which not only simplifies the subsequent sorting process but also ensures the safety of operators. After the test by the test device, the qualified glass and broken waste residue are often mixed together and need to be sorted and cleaned manually, which not only has a large labor intensity but also may cause personnel scratches due to glass fragments.

[0023] The following is in conjunction with the appendix Figure 1-3 This application will be described in further detail.

[0024] This application discloses a fireproof glass performance testing fixture for the production of fireproof doors and windows.

[0025] Reference Figure 1 , Figure 2 and Figure 3A performance testing fixture for fireproof glass used in the production of fireproof doors and windows, comprising: The housing 1 has a combustion zone 101 and an impact zone 102 inside the housing 1. Specifically, the left and right sides of the inside of the housing 1 are the combustion zone 101 and the impact zone 102, respectively. An edge limiting mechanism 2 is located inside the housing 1 between the combustion zone 101 and the impact zone 102, and is used to limit the edge of the fireproof glass 5. Specifically, the top 11 of the housing 1 is provided with a feed inlet 1101 and a feed door 111 located at the feed inlet 1101; the bottom 12 of the housing 1 is provided with a discharge outlet 1201 and a discharge door 121 located at the discharge outlet 1201; the bottom 12 on the side of the discharge outlet 1201 is inclined downward, and the lowest position of the bottom 12 is also provided with a waste outlet 1202 and a waste slag door 122 installed at the waste outlet 1202; the edge limiting mechanism 2 is located between the feed door 111 and the discharge door 121; below the discharge door 121 A vertical discharge guide pipe 123 is installed on the bottom 12 of the box. The lower end of the discharge guide pipe 123 is provided with a receiving groove 14 and a first waste groove 15 connected to each other. The receiving groove 14 and the first waste groove 15 are movably located below the discharge guide pipe 123. The receiving groove 14 and the first waste groove 15 can be moved by conventional means such as sliding rails. The inside of the receiving groove 14 is also provided with a buffer elastic layer that is not easy to be damaged by glass. If the discharge guide pipe 123 outputs qualified fireproof glass 5, the receiving groove 14 is used to catch the fireproof glass 5. If the output is unqualified broken fireproof glass 5, the first waste groove 15 is used to catch the unqualified fireproof glass 5. The flame-spraying device 3 is located in the combustion zone 101 and is used to heat the fireproof glass 5. Specifically, the flame-spraying device 3 is a gas-fired spray gun. Impact mechanism 4, located in impact zone 102, is used to impact fireproof glass 5 from multiple directions.

[0026] Reference Figure 1 , Figure 2 and Figure 3In this embodiment, after the fireproof glass 5 enters the box 1 through the feeding door 111, it is limited by the edge limiting mechanism 2 around the edge of the fireproof glass 5. The fireproof glass 5 is then sprayed with flames by the flame-spraying device 3 to test its fireproof performance. After the fireproof glass 5 passes the fireproof performance test, the flame-spraying device 3 is maintained in the flame-spraying state. The fireproof glass 5 is then impacted from multiple directions by the impact mechanism 4 to test its impact resistance at high temperatures. After the fireproof glass 5 is tested by the flame-spraying device 3 and the impact mechanism 4, the intact and qualified fireproof glass 5 is discharged through the discharge door 121 and received by the receiving trough 14. It is then removed by conventional material transfer devices such as a robotic arm. The broken, substandard fireproof glass 5, some glass fragments are discharged through the discharge door 121 and fall into the first waste trough 15 for collection, while the other glass fragments slide along the bottom 12 of the box and are discharged through the waste slag door 122. A second waste trough can be set below the waste slag door 122 to collect the waste slag discharged from the waste slag door 122.

[0027] Reference Figure 1 , Figure 2 and Figure 3 The edge limiting mechanism 2 includes; Bottom edge limiting component 21 is used to limit the bottom edge of the fireproof glass 5; Side limiting component 22 is used to limit the two vertical sides of the fireproof glass 5; The top edge limiting component 23 is used to limit the top edge of the fireproof glass 5.

[0028] Reference Figure 1 , Figure 2 and Figure 3 Specifically, the bottom edge limiting component 21 includes; The bottom U-shaped plate 211 is vertically installed at the discharge gate 121 and connected to the bottom of the box 12. The U-shaped groove of the bottom U-shaped plate 211 is set towards the impact area 102. The bottom edge pressure plate 212 is parallel to the bottom of the U-shaped groove of the bottom edge U-shaped plate 211 and can move toward the bottom of the U-shaped groove of the bottom edge U-shaped plate 211. Specifically, the side of the bottom edge pressure plate 212 away from the bottom edge U-shaped plate 211 is connected to the box wall 13 through the first telescopic member 213. Here, the first telescopic member 213 is the first cylinder. The telescopic shaft of the first cylinder is located inside the box 1 and connected to the bottom edge pressure plate 212. The main body of the first cylinder is located outside the box 1 and is not easily burned by the flame-spraying device 3. The discharge door 121 is used to carry the fireproof glass 5, and the bottom edge pressure plate 212 is used to press the bottom edge of the fireproof glass 5 onto the bottom of the U-shaped groove of the bottom edge U-shaped plate 211.

[0029] Reference Figure 1 , Figure 2 and Figure 3Specifically, the side limiting component 22 includes; There are two side U-shaped plates 221, which are positioned opposite each other directly above the bottom U-shaped plate 211 and are movably connected to the housing 1 along the horizontal length of the bottom pressure plate 212. Specifically, a side slide rail 223 parallel to the bottom pressure plate 212 is provided on the side of the side U-shaped plate 221. The side U-shaped plate 221 is slidably connected to the side slide rail 223 via side sliders 222. A bidirectional lead screw 224 is provided inside the side slide rail 223 for rotational connection. The two side sliders 222 are screwed to both ends of the bidirectional lead screw 224 respectively. By rotating the bidirectional lead screw 224, the two side sliders 222, i.e. the two side U-shaped plates 221, are driven to move closer or further apart, so that the two side U-shaped plates 221 can clamp the fireproof glass 5 to be tested. A motor 225 is provided at one end of the bidirectional lead screw 224 and installed outside the housing 1. The motor 225 drives the bidirectional lead screw 224 to rotate.

[0030] The side wall of the U-shaped groove of the side U-shaped plate 221 is coplanar with the bottom of the U-shaped groove of the bottom U-shaped plate 211, and the other side wall of the U-shaped groove of the side U-shaped plate 221 is set towards the impact zone 102.

[0031] Reference Figure 1 , Figure 2 and Figure 3 Specifically, the top edge limiting component 23 includes; Multiple lifting plates 231 are evenly distributed along the horizontal length of the bottom edge pressure plate 212. The feed door 111 is slidably connected to the top of the box 11. The lifting plates 231 are installed on the feed door 111 in a liftable manner. Specifically, the top of the lifting plate 231 is connected to the feed door 111 through a vertically set second telescopic member 232. The lifting plate 231 is driven to rise and fall by the extension and retraction of the second telescopic member 232. A V-shaped groove 230 is located at the bottom end of the lifting plate 231. The V-shaped groove 230 is composed of a first groove wall 2301 and a second groove wall 2302 that intersect at their top ends. The first groove wall 2301 is coplanar with the bottom of the U-shaped groove of the bottom U-shaped plate 211, and the second groove wall 2302 is positioned facing the impact area 102. After the two side U-shaped plates 221 can clamp the fireproof glass 5 to be tested, all the lifting plates 231 between the two side U-shaped plates 221 descend, causing the V-shaped groove 230 to clamp the top edge of the fireproof glass 5 to be tested.

[0032] The first groove wall 2301, the bottom of the U-shaped groove of the bottom U-shaped plate 211, and the side groove walls of the U-shaped grooves of the two side U-shaped plates 221 cooperate with each other to support the edge of the fireproof glass 5 away from the impact mechanism 4, thereby ensuring that the edge of the fireproof glass 5 can be fully and effectively supported when the impact mechanism 4 impacts the fireproof glass 5.

[0033] Reference Figure 1 , Figure 2 and Figure 3 In this embodiment, before testing, the feed gate 111 is slid open, and the motor 225 drives the bidirectional lead screw 224 to rotate, causing the two side U-shaped plates to move away from each other along the side slide rail 223. The first cylinder retracts, causing the bottom edge pressure plate 212 to move away from the bottom of the U-shaped groove of the bottom U-shaped plate. The second telescopic member 232 extends, causing the lifting plate 231 to rise, so that the edge limiting mechanism 2 is in a fully released state. The fireproof glass 5 to be tested is placed in the box, with its bottom edge placed on the discharge gate 121 and in contact with the bottom of the U-shaped groove of the bottom U-shaped plate, and the edge away from the impact mechanism 4 aligned with one side wall of the U-shaped groove. Then, the first cylinder is activated, its telescopic shaft pushes the bottom edge pressure plate 212 towards the bottom of the groove, pressing and fixing the bottom edge of the glass. The motor 225 drives the bidirectional lead screw 224 in the opposite direction, causing the two side U-shaped plates to move closer to each other along the slide rail until one side wall of the U-shaped groove of the side U-shaped plate is in contact with the vertical edges of the glass, completing the horizontal limiting. Then, the second telescopic component 232 retracts, causing multiple evenly distributed lifting plates 231 to descend synchronously, so that the V-shaped groove at the bottom end is precisely engaged with the top edge of the glass, and the first groove wall 2301 is in contact with the edge of the glass away from the impact mechanism 4, achieving top edge fixation. After the heating and impact tests are completed, the second telescopic component 232 first extends to raise the lifting plate 231, the motor 225 drives the bidirectional lead screw 224 to separate the side U-shaped plates, and the first cylinder retracts to release the bottom edge pressure plate 212, releasing the limiting in all directions, facilitating the discharge of glass or waste.

[0034] Reference Figure 1 , Figure 2 and Figure 3The edge limiting mechanism 2, through the precise coordination of the bottom edge limiting component 21, the side edge limiting component 22, and the top edge limiting component 23, constructs a three-dimensional support and fixing structure for the fireproof glass 5. After the fireproof glass 5 falls vertically onto the discharge gate 121, the bottom of the U-shaped groove of the bottom edge limiting component 21 provides a bottom bearing surface. The first cylinder drives the bottom edge pressure plate 212 to move parallel, pressing the bottom edge of the glass tightly against the bottom of the groove, forming a stable bottom constraint. The side limiting component 22, driven by the bidirectional lead screw 224 driven by the motor 225, moves the two side U-shaped plates synchronously closer or further away along the slide rail. The side U-shaped plate groove wall limits the vertical edge of the fireproof glass 5, and the bottom of the grooves of the two side U-shaped plates clamps the fireproof glass 5. At the same time, its design, which is coplanar with the bottom of the bottom U-shaped plate groove, ensures that the glass force-bearing surface is flat. The top limiting component 23 controls the lifting plate 231 to rise and fall through the second telescopic component 232. The first groove wall 2301 of the V-shaped slot is coplanar with the bottom of the bottom U-shaped plate groove and the side U-shaped plate groove wall of the impact mechanism 4, and together they support the edge of the glass away from the impact mechanism 4, thereby ensuring that the edge of the fireproof glass 5 can be fully and effectively supported when the impact mechanism 4 impacts the fireproof glass 5. The bottom edge limiting component 21, side edge limiting component 22, and top edge limiting component 23 form a closed-loop support, ensuring that the edges of the fireproof glass 5 remain stably supported and are not easily displaced or shaken when subjected to high temperatures and multi-directional impacts. Simultaneously, the spacing between the bottom edge pressure plate 212 and the bottom edge U-shaped plate 211, the spacing between the two side U-shaped plates 221, and the height of the lifting plate 231 can be freely adjusted, allowing the bottom edge limiting component 21, side edge limiting component 22, and top edge limiting component 23 to work together to clamp rectangular fireproof glass 5 of various sizes.

[0037] Reference Figure 1 , Figure 2 and Figure 3 Specifically, the impact components include; Magnetic plate 46 is installed on the end of guide rod 44 away from hammer 45; Pressure sensor 461, connected to magnetic plate 46 and guide rod 44; An electromagnet 47 is located on the side of the magnetic plate 46 away from the guide rod 44, and is movably connected to the guide tube 43 along the length of the guide rod 44. Specifically, one end of the guide rod 44 is connected to the guide tube 43 through a fourth telescopic member 471.

[0038] Reference Figure 1 , Figure 2 and Figure 3Specifically, in this embodiment, after the fireproof glass 5 is fixed by the edge limiting mechanism 2, the lifting cylinder drives the alignment plate 41 to rise and fall along the box wall 13, adjusting it to a preset height directly opposite the glass, thus aligning the striking hammer 45 with the center of the fireproof glass 5. Subsequently, through the coordinated extension and retraction of multiple third telescopic components 431, the guide tube 43 is pushed to drive the ball head 421 to rotate within the ball socket 42, adjusting the impact angle of the striking hammer 45 to meet multi-directional testing requirements. The fourth telescopic component 471 extends to push the electromagnet 47 toward the magnetic plate 46 until the electromagnet 47 can attract the magnetic plate 46. Then, the fourth telescopic component 471 shortens and drives the guide rod 44 toward the outside of the housing 1 until the hammer 45 abuts against the guide tube 43. The electromagnet 47 instantly changes the direction of current flow, so that the magnetic attraction force attracting the magnetic plate 46 becomes the magnetic repulsion force repelling the magnetic plate 46. Under the action of the magnetic repulsion force, the guide rod 44 drives the hammer 45 to move quickly toward the fireproof glass 5, completing one impact. The pressure sensor 461 monitors the magnitude of the impact force in real time. Then, the electromagnet 47 changes the current direction again, and the fourth telescopic member 471 extends again, pushing the electromagnet 47 towards the magnetic plate 46 until the electromagnet 47 can attract the magnetic plate 46. Then, the fourth telescopic member 471 shortens, causing the guide rod 44 to move outward from the housing 1 until the striking hammer 45 abuts against the guide tube 43, that is, after the striking hammer 45 resets, the striking hammer 45 strikes the fireproof glass 5 again. This cycle is repeated, causing the striking hammer 45 to strike a certain position of the fireproof glass 5 multiple times. By judging the damage to the fireproof glass 5, the strength of the fireproof glass 5 at that position is tested. If the fireproof glass 5 is not damaged, it means that the strength of the fireproof glass 5 is qualified. If multiple or different impacts are required, the above angle adjustment and force-accumulating impact steps are repeated until all impact tests are completed.

[0039] The implementation principle of the performance testing fixture for fireproof glass 5 used in the production of fireproof doors and windows in this application embodiment is as follows: At the start of the test, the feed door 111 is slid open first, and the fireproof glass 5 to be tested is placed vertically into the chamber 1. At this time, the edge limiting mechanism 2 is in the released state: the side U-shaped plates 221 separate from each other, the bottom edge pressure plate 212 retracts, and the top lifting plate 231 rises.

[0040] Subsequently, the fireproof glass 5 is placed in position, with its bottom edge resting on the discharge gate 121 and conforming to the bottom of the U-shaped groove of the bottom U-shaped plate 211. Simultaneously, it is ensured that the edge of the glass away from the impact mechanism 4 is aligned with one side wall of the U-shaped groove. The limiting procedure is initiated: the first telescopic component 213 drives the bottom edge pressure plate 212 downwards to fix the bottom edge of the glass; the motor 225 drives the bidirectional lead screw 224, causing the side U-shaped plates 221 on both sides to move synchronously towards each other, clamping the vertical edges of the glass; the second telescopic component 232 retracts, causing multiple lifting plates 231 with V-shaped slots 230 to descend and clamp the top edge of the glass. At this point, one edge of the fireproof glass 5 is fully and effectively limited.

[0041] Next, the flame-spraying device 3 in the combustion zone 101 is activated to continuously burn the glass to test its fire resistance. By judging the damage to the fireproof glass 5, the fire resistance performance of the fireproof glass 5 is tested. If the fireproof glass 5 is undamaged, it means that the fire resistance performance of the fireproof glass 5 is qualified. If the fire resistance performance is unqualified, the fireproof glass 5 is directly judged as unqualified and can be directly discharged as waste through the discharge door 121 without further testing by the impact mechanism 4.

[0042] After the fire resistance test is passed, the flame is maintained, and the impact mechanism 4 begins to operate. The lifting cylinder first drives the alignment plate 41 to rise and fall, aligning the striking hammer 45 with the center area of ​​the fireproof glass 5. Then, through the coordinated extension and retraction of multiple third telescopic components 431, the guide tube 43 is pushed, causing the ball head 421 to rotate within the ball socket 42, thereby adjusting the impact angle of the striking hammer 45. When ready to strike, the fourth telescopic component 471 pushes the electromagnet 47 forward to attract the magnetic plate 46, then retracts, pulling the guide rod 44 connected to the striking hammer 45 backward to the charging position (the striking hammer 45 abuts against the guide tube 43). Subsequently, the electromagnet 47 instantly changes the current direction, converting the attraction force into a repulsive force. Under the action of the magnetic repulsion, the guide rod 44 drives the striking hammer 45 to strike the fireproof glass 5 at high speed, completing a powerful impact. The impact force is monitored in real time by the pressure sensor 461. Afterwards, the current of the electromagnet 47 switches again, re-attracting the magnetic plate 46, and pulling the hammer 45 back to its original position via the fourth telescopic component 471, allowing for multiple, multi-angle impact tests to be performed cyclically. By judging the damage to the fireproof glass 5, the strength of that location of the fireproof glass 5 can be tested. If the fireproof glass 5 is undamaged, it indicates that the strength of the fireproof glass 5 is qualified.

[0043] After the test, the edge limiting mechanism 2 is completely released. Intact, qualified glass falls through the discharge gate 121 and slides into the receiving trough 14 via the discharge guide pipe 123. Broken glass fragments also fall through the discharge guide pipe 123 into the first waste trough 15, while the remaining fragments slide along the inclined bottom 12 to the waste gate 122 and fall into the second waste trough, achieving automatic sorting and collection.
