DETAILED DESCRIPTION

[0030] As shown in Figures 1-9 The detection device provided in the embodiment includes a sample fixing assembly 100, an electromagnetic driving impact test assembly 200 and an adjusting frame 300. The sample fixing assembly 100 is connected with the adjusting frame 300, and the electromagnetic driving impact test assembly 200 is arranged on the adjusting frame 300. The sample fixing assembly 100 is provided with a glass plate clamping jaw 101, which is configured to clamp and fix the laminated glass. The electromagnetic driving impact test assembly 200 includes an impact body 201, an impact acceleration track 202 and an alternating current electromagnetic acceleration coil 203. The impact body 201 and the alternating current electromagnetic acceleration coil 203 are arranged on the impact acceleration track 202. The material of the impact body 201 includes a magnetic metal, and the alternating current electromagnetic acceleration coil 203 is configured to electromagnetically accelerate the impact body 201. The adjusting frame 300 is slidably provided with a test assembly base 305, and the electromagnetic driving impact test assembly 200 is arranged on the test assembly base 305.
[0031] In use, the alternating current electromagnetic acceleration coil 203 in the electromagnetic driving impact test assembly 200 accelerates the impact body 201 through electromagnetic force, so that the impact body 201 reaches a preset speed on the impact acceleration track 202 and is shot out. When the impact body 201 contacts the laminated glass clamped on the sample fixing assembly 100, the impact test is completed. The alternating current electromagnetic acceleration coil 203 accurately controls the acceleration of the impact body by adjusting the size, frequency and duration of the current, so as to accurately adjust the speed of the impact body, and further simulate impact scenes of different intensities.
[0032] The alternating electromagnetic acceleration coil 203 makes the acceleration process of the impact body 201 more controllable and accurate. By adjusting the current intensity and frequency of the alternating electromagnetic acceleration coil 203, the speed and acceleration of the impact body 201 can be accurately controlled, and the impact energy and impact speed can be adjusted. This not only enables fast and stable acceleration of the impact body, but also allows adjustment of the mass and speed of the impact body under different test conditions to meet the test requirements of laminated glass samples of different thicknesses.
[0033] The embodiment also includes adjusting the frame 300 and the sliding test assembly base 305 thereon, so that the electromagnetic drive impact test assembly 200 can be accurately adjusted in multiple directions. By adjusting the position and angle of the test assembly base 305, multi-angle impact tests of the impact body can be realized, such as simulating vertical, inclined, and other different angle impacts. This makes the device flexible to adapt to various test requirements, especially for impact performance tests of laminated glass in different application environments, providing higher flexibility.
[0034] The electromagnetic drive impact test assembly 200 is arranged on the test assembly base 305. By adjusting the position of the test assembly base 305, the posture of the electromagnetic drive impact test assembly 200 can be accurately adjusted, thereby realizing flexible adjustment of the impact angle and position.
[0035] In this embodiment, the electromagnetic drive impact test assembly 200 further includes a laser pointer 204, which is accurately installed on the test assembly base 305 and aligned parallel to the impact acceleration track 202. The laser pointer 204 forms a parallel indication light path with the motion track of the impact body 201 by emitting a laser beam. When performing an impact test, the laser emitted by the laser pointer 204 will project a clear point on the laminated glass sample. By observing the position of the laser projection, the tester can accurately determine the landing point of the impact body 201, thereby ensuring the accuracy of the impact test.
[0036] With the assistance of the laser pointer 204, the tester can intuitively monitor the landing point of the impact body without relying on calculation or manual adjustment of the equipment position, thereby reducing the possibility of human error and making it easier to perform multiple accurate impacts in a specific area. This is suitable for scenarios that require fine impact tests at specific positions or angles.
[0037] The impact acceleration track 202 in the embodiment is provided with a plurality of track rollers 207 on the bottom of the track in the direction array, each track roller 207 is connected with the impact acceleration track 202 through rotation, and the track roller 207 enables the impact body 201 to move smoothly on the track; when the impact test is performed, the impact body 201 accelerates along the path of the track roller 207 and is finally shot out, the rotation of the track roller 207 reduces the friction between the impact body 201 and the impact acceleration track 202, so that the impact body can move more smoothly along the track, ensures that the impact body maintains a stable trajectory during acceleration, reduces energy loss and speed fluctuation caused by friction, and thus improves the accuracy and consistency of the test.
[0038] The electromagnetic drive impact test assembly 200 in the embodiment further includes a recovery pull line 205 and a winch line drum 206, both ends of the recovery pull line 205 are connected to the impact body 201 and the winch line drum 206 respectively, when the impact test is performed, the alternating current electromagnetic acceleration coil 203 pushes the impact body 201 to accelerate and shoot out along the impact acceleration track 202 through electromagnetic force, and the impact body 201 drags the recovery pull line 205 during movement along the track; after the impact body 201 hits the laminated glass sample, the recovery pull line 205 begins to be tightened, and the winch line drum 206 automatically pulls the impact body 201 back to the original position by winding the recovery pull line 205, and through this recovery system, the impact body 201 can quickly and smoothly return to the impact acceleration track 202, ready for the next test.
[0039] Through the cooperation of the recovery pull line and the winch line drum, the impact body 201 can be quickly and automatically recovered after each test, reducing the complexity of manual intervention and operation, thereby saving time and labor cost, and at the same time, the automatic recovery mechanism ensures the stability and accuracy of the impact body 201, so that the impact body can be quickly re-injected into the next test, maintaining the efficiency of the test, improving the experimental efficiency and reducing the equipment wear.
[0040] The sample fixing assembly 100 in the embodiment includes a fixing back plate 102, a clamping jaw adjusting groove 106, a fixing bolt 104 and an impact pad lining plate 105, the glass plate clamping jaw 101 is fixed in the clamping jaw adjusting groove 106 through the fixing bolt 104, the clamping jaw adjusting groove 106 is designed as an adjustable structure, allowing the position of the glass plate clamping jaw 101 on the fixing back plate 102 to be adjusted according to different sizes of glass samples, and the tester can flexibly adjust the position of the clamping jaw according to the actual size of the sample, so as to ensure that the clamping jaw can stably clamp laminated glass of various sizes and ensure the stability of the glass during the impact test.
[0041] In addition, the fixed back plate 102 is further provided with an impact pad lining plate 105, which is located between the fixed back plate 102 and the laminated glass. The impact pad lining plate 105 reduces the risk of uneven pressure on the glass sample, ensures the stability of the glass during the test, and prevents friction or damage that may occur when the fixed back plate 102 directly contacts the laminated glass.
[0042] In this embodiment, the adjusting frame 300 includes key components such as a rotating joint 302, a lifting bracket 303, and a vertical rail 304. The lifting bracket 303 is connected to the adjusting frame through the rotating joint 302, so that the lifting bracket 303 can realize rotational motion under the action of the rotating joint 302. The vertical rail 304 is provided on the lifting bracket 303, and the test assembly base 305 is slidingly installed in the vertical rail 304 and can freely ascend and descend and rotate in the rail. When the test assembly base 305 moves up and down along the vertical rail 304 or rotates, the electromagnetic drive impact test assembly 200 on the test assembly base 305 also adjusts with the movement of the base, so that the impact body 201 can impact the laminated glass at different angles and positions, ensuring that the device can flexibly adapt to different experimental requirements and simulate various impact angles and positions.
[0043] Through the cooperation of the lifting bracket 303 and the rotating joint 302, the adjusting frame 300 can realize multi-angle and multi-position adjustment of the electromagnetic drive impact test assembly 200, so that the device can simulate more complex impact situations, such as the case where the laminated glass is subjected to an inclined or inclined impact, thereby more realistically reflecting the impact situation in actual application.
[0044] The adjusting frame 300 proposed in this embodiment further includes a mobile chassis 301, and the rotating joint 302 is arranged on the mobile chassis 301. Then the lifting bracket 303 is arranged on the rotating joint 302, and the lifting bracket 303 can realize rotation through the rotating joint 302. Meanwhile, the bottom of the mobile chassis 301 is provided with a set of mobile wheels 306, and the mobile chassis 301 can move by means of the set of mobile wheels 306. When the lifting bracket 303 moves and rotates with the mobile chassis 301, the test assembly base 305 moves synchronously, thereby realizing posture adjustment of the electromagnetic drive impact test assembly 200, so that the height, position, and pointing angle of the electromagnetic drive impact test assembly 200 can be adjusted, and impact tests at various angles and positions can be realized.
[0045] Meanwhile, the fixed back plate 102 is provided with a test rail 103, and the mobile chassis 301 moves on the test rail 103. The movement range of the mobile chassis 301 is limited by the test rail 103, so that the mobile chassis 301 can move along a specific path when needed.
[0046] In this embodiment, the lifting support 303 is provided with a support rod 307 to improve the stability of the lifting support 303 during operation. When the center of gravity of the electromagnetic drive impact test assembly 200 is at a high position, the support rod 307 can support the lifting support 303 to ensure that it does not tilt or become unstable during rotation or lifting. The bottom of the support rod 307 is provided with a universal wheel 308, which can adjust the position of the support rod 307 as it moves when the lifting support 303 rotates or moves, providing more flexible support. The universal wheel 308 not only ensures smooth movement of the lifting support 303 during rotation, but also allows convenient adjustment of the position of the support rod 307 when needed, ensuring the balance and stability of the overall system.
[0047] When using the laminated glass detection device of the present embodiment, first check that all parts of the device are working properly and ensure that the electromagnetic drive impact test assembly, the adjustment frame and the sample fixing assembly are intact. Fix the laminated glass sample on the sample fixing assembly and adjust the clamping jaw to ensure that the sample is securely fixed. According to the test requirements, adjust the height, position and angle of the test assembly base through the lifting support and the rotating joint, and use the laser pointer to calibrate the accurate impact point of the impact body. After starting the electromagnetic acceleration system, adjust the acceleration coil current to accelerate the impact body, and observe its smooth acceleration along the track. During the impact test, the impact body hits the glass sample and records the impact data. After the test, the impact body is automatically recovered by the recovery line and the winch drum, and the next test is prepared. Adjust the equipment as needed for multiple impact tests, ensure the accurate position and angle of each impact through the laser pointer, complete data recording and analysis, and finally clean the equipment and check all parts for necessary maintenance and maintenance.
