Description

Technical Field

[0001] This utility model relates to the fields of traffic engineering and material mechanical property testing technology, and in particular to a high-precision anti-glare plate deformation resistance testing device. Background Technology

[0002] On highway medians, anti-glare panels, as key traffic safety products, effectively block glare from oncoming headlights, reduce visual interference for drivers, and improve driving safety. Currently, the market offers a variety of anti-glare panels, including standard straight panels, inverted S-shaped panels, embossed panels, and highway landscape anti-glare panels. According to the national standard "Anti-glare Panels" (GB / T24718-2023), the height of anti-glare panels is typically between 700 and 1000 mm, and the width between 80 and 250 mm. Their resistance to deformation is one of the key indicators for evaluating the quality of anti-glare panels.

[0003] In testing the deformation resistance of anti-glare panels, a common method is to apply a load, measure the projection difference (S1-S0) at a point on the top of the panel, and then divide it by the height H of the panel to calculate the deformation. However, existing testing methods have the following problems:

[0004] 1. Limited measurement accuracy

[0005] Because the standard does not specify key factors such as the type of test light source and the distance between the light source and the anti-glare plate, the light source conditions vary under different test environments, making it difficult to guarantee the accuracy of projection measurement and affecting the reliability of the test.

[0006] When manually measuring projection changes, operators need to repeatedly compare the measurements, which can easily lead to measurement deviations due to human error, making it difficult to meet the stringent technical requirement of ≤10mm / m.

[0007] 2. Location is quite difficult.

[0008] Existing testing methods typically use common measuring instruments (such as vernier calipers and optical projectors) to detect deformation, but they lack precise displacement control methods, resulting in low positioning accuracy of measurement points and affecting the accuracy and repeatability of deformation data.

[0009] Traditional methods of manually adjusting the height of measuring instruments are rather crude and cannot achieve high-precision focusing, which can easily lead to measurement deviations during testing.

[0010] 3. Outdated data acquisition methods make measurement results susceptible to external factors.

[0011] Existing testing methods mostly rely on manual readings or low-precision displacement measurement tools (such as ordinary displacement sensors), which cannot record measurement data in real time and are easily affected by factors such as equipment vibration and changes in ambient temperature during the measurement process.

[0012] Due to the lack of high-precision data acquisition devices, existing technologies have large errors when measuring minute deformations, making it difficult to guarantee the reliability of measurement data. Utility Model Content

[0053] Reference Figures 1-3 This first embodiment of the present invention provides a high-precision anti-glare panel deformation resistance testing device. This device can effectively solve the problems of low accuracy, difficult positioning, and unstable data recording in traditional measurement methods. It can efficiently and accurately measure the deformation resistance of the anti-glare panel after applying a load, as detailed below:

[0054] The device mainly consists of four parts: an observation module 100, a displacement driving module 200, a measurement feedback module 300, and a support leveling module 400, as detailed below:

[0055] Observation module 100: Used for precise measurement of the deformation of the anti-glare panel, including:

[0056] Microscope 101: It adopts a 600x high-definition industrial electron microscope with a screen, and has a built-in 4.3-inch high-definition OLED display. The display has a crosshair cursor, which makes it easy to align with the measurement position of the anti-glare plate. The LED light can work continuously for more than 6 hours.

[0057] Metal bracket 102: Used to fix the microscope and support its height adjustment to ensure the microscope is in focus.

[0058] Displacement drive module 200: Used to adjust the position of the observation module to achieve accurate measurement, and includes the following structural components:

[0059] Metal panel 201: One end is fixed to a metal bracket 102, and the other end is connected to a dual-axis ball screw slide 202.

[0060] Dual-axis ball screw slide 202: It consists of a motor 202a, a ball screw 202c, a slider panel 202b, and a base plate 202d. The motor controls the rotation of the ball screw, causing the slider panel to move along a straight trajectory to precisely adjust the position of the microscope.

[0061] Pulse generator 203: Used to control the rotation speed of motor 202a, realize the adjustment of the slide movement speed within the range of 0 to 100 mm / s, and ensure that the microscope can accurately align with the measurement point.

[0062] Measurement feedback module 300: Used for real-time acquisition of deformation displacement data, including:

[0063] Magnetic scale 301: It consists of a magnetic head 301a, a digital display 301b and a magnetic head wire 301c. The magnetic head is fixed to the back of the slider panel 202b and measures the stroke of the slider with a measurement accuracy of 0.01mm.

[0064] Digital display 301b: Receives the displacement signal collected by the magnetic head 301a through the magnetic head line 301c and displays the displacement data in real time.

[0065] Support leveling module 400: Ensures the stability and levelness of the device, including:

[0066] Box 401: The load-bearing part of the overall structure, made of aluminum alloy.

[0067] 402 level bubble: Used to check whether the device is installed horizontally.

[0068] Adjustable leveling mechanism 403: includes four sets of adjustable leveling bolts 403a, which are rectangularly distributed at the four corners of the bottom of the box 401, and are used to adjust the horizontal state of the device.

[0069] Each set of adjustable leveling bolts 403a includes a screw 403a-1, a locking nut 403a-2, a support washer 403a-3, and an anti-slip base 403a-4, ensuring that it can be locked in a stable position after adjustment;

[0070] The support washer 403a-3 is arranged at the top of the locking nut 403a-2, contacts the lower surface of the housing 401, and is sleeved with the screw 403a-1;

[0071] The locking nut 403a-2 is threadedly connected to the screw 403a-1. One end of the screw 403a-1 is screwed into the threaded hole 401a at the bottom of the housing 401, and the other end is connected to the anti-slip base 403a-4 to increase the stability of contact with the ground.

[0072] Test module 500, such as Figure 1 As shown, the components arranged on the test bench to provide power for testing the deformation resistance of the anti-glare panel include an electronic tensile testing machine 501, a traction rope 502, and a pulley 503. The electronic tensile testing machine 501 is connected to the anti-glare panel sample via the traction rope 502, and the pulley 503 is used to change the direction of force on the traction rope 502, making the force loading more stable and precise.

[0073] The specific working process of this device is as follows:

[0074] S1: Leveling and Initialization:

[0075] Check if the device is level using the bubble level 402. If it is not level, adjust it using the adjustable leveling mechanism 403 until it is level. The specific steps are as follows:

[0076] Rotate the corresponding adjustable leveling bolt 403a to adjust the height of the device at different support points so that the level bubble 402 is in the center position, ensuring that the device reaches the ideal level state.

[0077] After leveling is completed, lock the support shim 403a-3 by tightening the lock nut 403a-2, and then lock the screw 403a-1. The support shim 403a-3 stabilizes the support box 401 and prevents the device from tilting.

[0078] Start the pulse generator 203 and microscope 101, and move the microscope to the initial measurement position of the anti-glare plate.

[0079] S2: Pre-measurement positioning:

[0080] By adjusting the focus of the microscope to make the image clearly visible, the initial measurement point O on the top of the anti-glare plate is locked and marked using the crosshair cursor.

[0081] S3: Apply load:

[0082] According to GB / T24718-2023 standard, the electronic tensile testing machine 501 uses a traction rope 502 to guide the anti-glare panel sample (such as...) Figure 1 As shown, the anti-glare plate is fixed on the anti-glare plate support platform to ensure that the anti-glare plate remains stable during the measurement process and to avoid external interference. The standard load is applied to simulate the stress of the anti-glare plate under actual working conditions.

[0083] S4: Measure the deformation:

[0084] After unloading the load, zero the magnetic grating ruler 301.

[0085] Move the microscope 101 again and adjust it to the initial mark point O so that the crosshair cursor is aligned with the point again. At this time, the displacement recorded by the magnetic scale 301 is the deformation L.

[0086] Calculate the deformation amount S = L / H to complete the measurement of the anti-glare plate's deformation resistance.

[0087] Example 2

[0088] Reference Figure 2 This is the second embodiment of the present invention. The difference between this embodiment and the first embodiment is that, based on embodiment 1, the metal support 102 is optimized to improve the height adjustment accuracy of the microscope 101, allowing the microscope to more flexibly adapt to anti-glare plates of different heights. Specifically, the following is a detailed description:

[0089] The bottom of the metal bracket 102 is fixed to the metal panel 201 with bolts to ensure stability.

[0090] The outer periphery is provided with an external thread structure, and the height of the microscope 101 can be adjusted by rotating the thread structure, thereby changing the distance between the microscope and the anti-glare plate, enabling the microscope to focus quickly and improve measurement accuracy.

[0091] This embodiment improves the positioning accuracy of the microscope by optimizing the structure of the metal support 102, avoiding errors caused by repeated manual adjustment of the focus; it also increases adaptability, allowing for flexible adjustment to anti-glare plates of different thicknesses, thus improving the versatility of the testing equipment.

[0092] Example 3

[0093] Reference Figure 2 This is the third embodiment of the present invention. This embodiment differs from the first embodiment in that, based on embodiment 1, the structure of the dual-axis ball screw slide 202 is optimized to improve the slide's motion stability and load-bearing capacity, as detailed below:

[0094] The 202c ball screw uses a 16mm diameter screw, with a stroke of 5mm per revolution and an effective stroke of 400mm.

[0095] The slider panel 202b is fixedly connected to the base plate 202d to improve the stability of the slider during movement and prevent vibration from affecting the measurement accuracy.

[0096] This embodiment optimizes the structure of the dual-axis ball screw slide 202, making the slide run more smoothly and avoiding measurement errors caused by vibration.

[0097] The 202a motor offers higher driving precision, ensuring that the microscope 101 can be accurately aligned with the measurement position and improving measurement repeatability.

[0098] Example 4

[0099] Reference Figures 1-2 This is the fourth embodiment of the present invention. This embodiment differs from the first embodiment in that, based on embodiment 1, the magnetic scale 301 and the data acquisition system are optimized to further improve measurement accuracy and data transmission stability, as detailed below:

[0100] The magnetic head 301a is fixed to the back of the slider panel 202b to ensure stable measurement of displacement data when the slider moves.

[0101] The digital display 301b is fixed to the side wall of the housing 401 by a snap fastener to prevent external vibrations from affecting the reading accuracy.

[0102] The magnetic scale 301 has a detection accuracy of 0.01mm, which can accurately record minute deformations.

[0103] This embodiment improves the measurement accuracy of the device and ensures the reliability of the measured deformation through the above structural optimization.

[0104] Automatic data recording reduces human error and improves the standardization of testing.

[0105] In summary, this implementation scheme improves the accuracy, stability, and automation of anti-glare plate deformation measurement through multiple optimizations, including microscope positioning, slide driving, and data measurement and recording. This makes the device significantly more advantageous than traditional methods in terms of accuracy, ease of operation, and data reliability.

[0106] It should be understood that numerous specific implementation decisions can be made during the development of any practical implementation, such as in any engineering or design project. Such development efforts may be complex and time-consuming, but for those skilled in the art who benefit from this disclosure, the development effort will be a routine work of design, manufacturing, and production without requiring much experimentation.

[0107] It should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solution of this utility model without departing from the spirit and scope of the technical solution of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
