Its impact resistance is an important indicator to measure the ability of the thermal insulation decorative panel to resist impact loads. Traditional impact test methods rely on manual operation. The impact resistance test is carried out by a staff member holding a steel ball at a certain height and releasing it. Steel balls with different diameters freely fall from a specific height to impact the thermal insulation decorative panel specimen, and then the crack conditions generated on the surface of the specimen are observed to evaluate the impact resistance of the thermal insulation decorative panel. By analyzing the crack morphology, quantity, and distribution of the specimen after impact, the strength of its impact resistance is judged.

[0003] However, traditional impact test methods have certain limitations. First, it is difficult to accurately control the position height of the steel ball, the spacing between impact points, and the distance between the impact point and the edge in actual operation relying on manual experience. During the process of holding the steel ball by hand, the arm shakes, causing offsets in the horizontal and vertical directions, so errors are likely to occur. These errors may lead to inaccurate test results and affect the objective evaluation of the impact resistance of thermal insulation decorative panels.

[0004] Therefore, there is an urgent need for a test device that can accurately control the position height of the steel ball, the spacing between impact points, and the distance between the impact point and the edge to improve the accuracy and reliability of the test, so as to more scientifically evaluate the impact resistance of thermal insulation decorative panels.

Specific embodiments

[0025] In order to enable those skilled in the art of the present technology to better understand the technical solutions in this application, the following will clearly and completely describe the technical solutions in the embodiments of this application with reference to the accompanying drawings in the embodiments of this application. Obviously, the described embodiments are only a part of the embodiments of this application, rather than all the embodiments. Based on the embodiments in this application, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the scope of protection of this application.

[0026] The thermal insulation decorative board is a composite board prefabricated in a factory, which is composed of a thermal insulation core material and a decorative surface layer through a special adhesive and connecting components, and has both the dual functions of building thermal insulation and decoration. Its impact resistance is an important index to evaluate the ability of the board to resist dynamic loads, and directly affects the service life and safety performance of the product.

[0027] According to the provisions of the industry standard JG / T 287-2013, the impact resistance test of the thermal insulation decorative board adopts a grading evaluation method, including:

[0028] 3J-level impact test: Use a steel ball with a nominal diameter of 50.8 mm to freely fall and impact the specimen from a height of 0.57 m;

[0029] 10J-level impact test: Use a steel ball with a nominal diameter of 63.5 mm to freely fall and impact the specimen from a height of 0.98 m.

[0030] The test requires that 10 test points be selected on the surface of the specimen for each impact level, and it is ensured that the distance between each impact point and the distance from the edge of the board are not less than 100 mm.

[0031] The traditional manual impact test method has obvious technical limitations. The operation process depends on manual experience, and it is difficult to guarantee the repeatability and reliability of the test results. For example, the height control accuracy is insufficient, and it is difficult to ensure the accuracy of the falling height of the steel ball; the impact point positioning is difficult, and it is impossible to accurately control the impact point spacing and the edge distance. The special device for detecting the impact resistance performance of the thermal insulation decorative board provided by this application is composed of a horizontal platform, an adsorption platform, a crack identification component and at least two support arms, as well as a magnetic attraction mechanism. By precisely controlling the on-off of the magnetic attraction component, the stable adsorption and free fall of the steel ball are realized, so as to ensure the precise positioning of the steel ball and complete the standardized test of the impact resistance performance of the thermal insulation decorative board.

[0032] The following will describe in detail the special device for detecting the impact resistance performance of the thermal insulation decorative board provided by this application with reference to the accompanying drawings.

[0033] Refer to Figure 1 as shown in Figure 1 FIG. 1 is a schematic structural diagram of a device for detecting the impact resistance performance of a thermal insulation decorative board provided for the implementation of this application. The device includes: a horizontal platform 1, an adsorption platform 2, a crack identification component 3 and at least two support arms 4. During assembly, the horizontal platform 1 is placed on the horizontal ground, and one end of the support arm 4 is slidably connected to the horizontal platform 1. Refer to Figure 1, a slide rail for installing the support arm 4 can be arranged at the edge of the horizontal platform 1. A sliding ring matching with the slide rail is arranged at the lower end of the support arm. The sliding ring is in sliding fit with the slide rail so that the lower end of the support arm 4 can slide along the edge of the horizontal platform 1. A braking device (not shown in the figure), such as a friction brake, an electromagnetic clamp, a micro hydraulic brake cylinder, etc., is arranged between the sliding ring and the slide rail, so that the support arm 4 can be kept in place after moving to a proper position, preventing the support arm 4 from sliding during the test. A clamp seat 43 is arranged at the other end of the support arm 4. The clamp seat 43 clamps and adsorbs the adsorption platform 2. The clamp seat 43 is in sliding fit with the adsorption platform 2, that is, the position of the support arm 4 relative to the adsorption platform 2 can be adjusted. Steel balls are adsorbed on the lower surface of the adsorption platform 2. A magnetic adsorption control component 6 is arranged at one end of the support arm 4 close to the adsorption platform 2, which is used to control the stable adsorption or free fall of the steel balls. In some embodiments, the adsorption platform 2 can adopt some transparent electromagnetic materials. Exemplarily, the transparent conductive electromagnetic composite material adopts a multi-layer composite structure, combining transparency, conductivity and magnetism. Among them, the base layer can adopt high light transmittance materials (such as tempered glass, transparent polycarbonate or flexible PDMS). Conductive layer: transparent conductive thin film (ITO, silver nanowire or graphene). Magnetic layer: transparent polymer (such as epoxy resin or polyurethane) uniformly dispersed with superparamagnetic nanoparticles (such as Fe3O4, CoFe2O4). When the adsorption platform 2 adopts a transparent electromagnetic material, the magnetic adsorption control component 6 is electrically connected to the adsorption platform 2. When the magnetic adsorption control component 6 controls the adsorption platform 2 to be powered on, the adsorption platform 2 has magnetism and generates an adsorption force to adsorb the steel balls. When the adsorption platform 2 is powered off, the magnetism of the adsorption platform 2 disappears, and the adsorption force of the adsorption platform 2 on the steel balls disappears, and the steel balls fall freely.

[0034] Referring to Figure 2 as shown in Figure 2Another structural schematic diagram of the impact resistance testing device for thermal insulation decorative panels provided for the implementation of this application. In some embodiments, the magnetic attraction control component 6 includes an electromagnet, which is located on the surface of the adsorption platform 2 away from the horizontal platform 1 and slides along the surface of the adsorption platform 2. At this time, the electromagnet is connected to any one of the support arms 4. When the position of the support arm 4 changes, the position of the electromagnet on the surface of the adsorption platform 2 also changes accordingly. The device also includes an electromagnet 61, which is connected to the magnetic attraction control component 6. The adsorption force generated by the electromagnet 61 penetrates the adsorption platform 2 to adsorb and control the steel ball. When energized, a strong magnetic field is generated to stably adsorb the steel ball on the platform surface; after power-off, the magnetic field disappears, and the steel ball freely falls under the action of gravity. Through the mobile layout of the electromagnet, both the structural simplicity of the device is maintained and the adjustable control of the adsorption position of the steel ball is achieved, providing a flexible operation space for the testing process. At this time, the adsorption platform 2 can be made of transparent material or non-transparent material. When the adsorption platform 2 is made of transparent material, the position of the steel ball (i.e., the impact resistance point during testing) can be located by means of the infrared light emitted by the infrared laser lamp. When the adsorption platform 2 is made of non-transparent material, the position of the steel ball can also be located by means of the infrared light emitted by the infrared laser lamp, or multiple positioning points can be preset on the side of the adsorption platform 2 close to the horizontal platform 1 as the positioning points of the steel ball. The positioning of the steel ball will be further described below and will not be elaborated here.

[0035] When performing the impact resistance test on the thermal insulation decorative panel, place the cut sample to be tested on the horizontal platform 1, start the magnetic attraction control component 6 to energize, so that the adsorption platform 2 generates magnetic force, and stably adsorb the steel ball on its surface facing the platform 1; after positioning is completed, cut off the power supply of the magnetic attraction control component 6, the magnetic force disappears, and the steel ball freely falls to impact the surface of the sample. By adjusting the position of the steel ball on the adsorption platform 2, repeated impact tests can be carried out on different areas of the sample. The crack identification component 3 is arranged above the horizontal platform 1 and connected to the support arm 4. After the test is completed or during the test, the cracks on the surface of the sample are observed through the crack identification component 3, and the distribution characteristics, quantity and morphological changes of the cracks are analyzed.

[0036] According to the regulations of the industry standard JG / T 287-2013, the test requires 10 test points to be selected on the surface of the specimen for each impact level, and it is ensured that the distance between each impact point and the distance from the edge of the plate are not less than 100 mm. In order to be able to more accurately determine the position of the impact point, this application also provides an auxiliary positioning component 5.

[0037] Refer to Figure 4 as shown Figure 4Schematic diagram of the installation position of the auxiliary positioning component in the impact resistance detection device for the thermal insulation decorative board provided by the embodiment of the present application. In some embodiments, the auxiliary positioning component 5 includes an infrared laser lamp 51. The support arm 4 is of a hollow structure. The infrared laser lamp 51 is arranged inside the support arm 4. A through hole 52 is provided on the side of the support arm 4 close to the adsorption platform 1 for the infrared light emitted by the infrared laser lamp 51 to transmit.

[0038] When the adsorption platform 2 is made of a transparent material, the infrared light emitted by the infrared laser lamp 51 can penetrate the adsorption platform 2. Exemplarily, the adsorption platform 2 is selected from optical grade polycarbonate (light transmittance ≥ 90%) or tempered glass material to ensure that the infrared light penetration loss < 5%. When the position of the support arm 4 moves, the auxiliary positioning component 5 moves accordingly. Therefore, the position of the infrared light in the adsorption platform 2 also changes. The infrared light emitted by the infrared laser lamps 51 in the two support arms 4 intersects in the adsorption platform 2 to form an intersection point, and this intersection point can be used as the positioning point of the steel ball. During the test, the operator visually observes the position of this intersection point, holds the steel ball and extends it below the adsorption platform 2, and places the steel ball at this intersection point to complete the positioning of the steel ball (because at this time the adsorption platform 2 is made of a transparent material, the operator's line of sight can penetrate the adsorption platform 2 from above the adsorption platform 2, and only need to extend the hand below the adsorption platform 2 to complete the placement of the steel ball).

[0039] When the adsorption platform 2 is made of a non-transparent material, the position of the through hole 52 corresponds to below the adsorption platform 2, that is, the infrared light emitted by the infrared laser lamp 51 passes through the space between the adsorption platform 2 and the horizontal platform 1, and this infrared light should be close to the surface of the adsorption platform 2. When placing the steel ball, the operator looks up from below the adsorption platform 2. After seeing the intersection point of the two infrared lights clearly, place the steel ball here (at this time, because the adsorption platform 2 is made of a non-transparent material, the line of sight cannot penetrate the adsorption platform. Therefore, the operator may need to bend down to observe the intersection point of the infrared lights from below the adsorption platform 2 to complete the positioning of the steel ball).

[0040] The auxiliary positioning component 5 uses the infrared laser lamp 51 and the hollow support arm 4, combined with the transparent adsorption platform 2, to be able to form a clear infrared light intersection point on the adsorption platform as the positioning point of the steel ball. This design not only improves the positioning accuracy but also enables the impact point during the test to be determined quickly and accurately, thus greatly improving the test efficiency.

[0041] When moving the two support arms 4, the position of the intersection point changes accordingly. Therefore, by moving the support arms 4, each impact point required for the test can be accurately positioned. The distance between each impact point can be controlled by the distance that the support arms 4 move. In some embodiments, scale markings can be provided at the slide rail of the horizontal platform 1. The bottom of the support arm 4 meshes with the slide rail of the horizontal platform 1, and scale markings are etched on the surface of the slide rail. The operator can accurately control the displacement of the support arm by observing the scale. In some other embodiments, a servo motor can be used to automatically control the movement of the support arm 4, and the displacement of the support arm 4 can be controlled through a program to achieve accurate positioning of the impact point. The flexible mobility of the support arm 4 enables the position of the infrared light on the adsorption platform 2 to be adjusted arbitrarily. By moving the support arm 4, the position of the intersection point can be easily changed, thereby achieving accurate positioning of different test points. In addition, the moving distance of the support arm 4 can also control the distance between each impact point, meeting the flexible adjustment under different test requirements.

[0042] In the embodiments of the present application, at least two support arms 4 are provided. When the two support arms 4 move, it should be ensured that the light rays emitted by the infrared laser lamps 51 located in the two support arms 4 intersect. When the number of support arms 4 is three or more, two of the support arms 4 can be selected for auxiliary positioning, and the remaining support arms 4 are used to support the adsorption platform 2 to ensure the stability of the adsorption platform 2. When two support arms 4 are used, a fixing device or component of the adsorption platform 2 can be additionally provided, which will not be elaborated here.

[0043] Refer to Figure 1 As shown, the support arm 4 includes an upper support arm 41 and a lower support arm 42. The upper support arm 41 is inserted into the hollow structure of the lower support arm 42 and slides along the inner wall of the lower support arm 42. A motor 7 is provided at one end of the lower support arm 42 close to the horizontal platform 1, which is used to control the up and down movement of the upper support arm 41, ensuring the stability and accuracy of the upper support arm 41 during the movement. The sliding connection between the upper support arm 41 and the lower support arm 42 can also be processed to improve the performance of the device. For example, high-precision sliding rails and wear-resistant materials are used to ensure the smoothness and stability of the upper support arm 41 during the sliding process. At the same time, in some embodiments, the sliding rail also has a certain self-locking function, which can prevent the upper support arm 41 from moving accidentally due to external forces even when the motor stops running.

[0044] Refer to Figure 3As shown, in some embodiments, the crack recognition component 3 includes a camera 31 and a control module; a clamping seat 43 is provided at one end of the support arm 4 close to the adsorption platform 2, and a camera mounting seat is provided below the clamping seat 43. The camera 31 is connected to the camera mounting seat; the control module is communicatively connected to the camera 31 to identify and analyze the images collected by the camera. As an example, the camera 31 can be a 5-megapixel industrial CCD camera, equipped with a 50-mm fixed-focus lens, ensuring that the micron-level crack features on the sample surface can be clearly captured. The control module runs a dedicated crack analysis software, supporting real-time image processing. The algorithm adopts a deep learning framework to automatically identify cracks and calculate parameters such as length, width, and number of branches. The traditional manual judgment time is shortened from 10 minutes / sample to 30 seconds / sample, and the results are objective and traceable. The gigabit Ethernet communication protocol is adopted, with a transmission rate of 1 Gbps, supporting the simultaneous transmission of original images and analysis data. The control module reserves RS485 and USB3.0 interfaces, compatible with laboratory data management systems. High-speed data transmission ensures delay-free display of images, and the multi-interface design enhances device compatibility. At the same time, the control module is connected to the human-machine interaction interface. For example, it is equipped with a 10.1-inch touch screen to display the crack distribution heat map and quantitative data in real time. Gesture zooming operations are supported, facilitating detailed observation. The intuitive visualization interface greatly reduces the technical requirements for operators and improves the detection efficiency.

[0045] In some embodiments, the crack recognition component 3 further includes a lighting lamp, and the lighting lamp is connected to the support arm 4. Among them, high-color-rendering-index LED lamp beads can be used for the lighting lamp, and they are installed in a 360° circular layout around the camera mounting seat to ensure shadowless lighting. The circular uniform lighting eliminates detection dead angles and ensures the integrity of crack imaging.

[0046] In some embodiments, a fence 11 is provided around the horizontal platform 1. It collects the freely falling steel balls, prevents the steel balls from rolling and causing injuries, and improves the safety of the test process.

[0047] In some embodiments, the upper support arm 41 has scale markings. Intuitively observe the telescopic degree of the upper support arm 41, visually display the telescopic degree of the upper support arm 41, facilitate the precise control of the height of the adsorption platform 2 from the horizontal platform 1, thereby precisely controlling the height of the steel ball drop, and improving the accuracy and repeatability of the test results.

[0048] Refer to Figure 5 As shown, Figure 5Schematic diagram of the positioning holes of the adsorption platform in the impact resistance testing device for thermal insulation decorative panels provided by the embodiments of the present application. In some embodiments, positioning holes 21 for steel ball positioning are provided on the surface of the adsorption platform 2 facing the horizontal platform 1. Precise positioning of the steel ball can also be achieved through the positioning holes, improving the accuracy and consistency of the test point layout, and further enhancing the reliability and precision of the test. In addition, when using the positioning holes 21 for positioning, an electromagnet can be provided in the positioning holes 21 to increase the adsorption force of the adsorption platform 2 on the steel ball. This avoids the displacement of the steel ball due to external force or vibration, thereby further improving the accuracy and reliability of the test. When using the positioning holes 21 for positioning, there is no need to set up an infrared laser lamp, simplifying the structure of the device and reducing the manufacturing cost.

[0049] The present application provides an impact resistance testing device for thermal insulation decorative panels, including a horizontal platform 1, an adsorption platform 2, a crack identification component 3, and at least two support arms 4. The horizontal platform 1 is provided with a slide rail, and the support arms 4 are slidably connected to the slide rail through slip rings and are equipped with a braking device to fix the position. The upper end of the support arm 4 is connected to the adsorption platform 2 through a clamp 43. The lower surface of the adsorption platform 2 can adsorb steel balls, and the adsorption / release is controlled by a magnetic attraction control component 6. An auxiliary positioning component 5 is arranged inside the support arm 4. Among them, as shown in Figure 4 Figure, the auxiliary positioning component 5 includes an infrared laser lamp 51. The infrared light emitted by the infrared laser lamps 51 located inside the two support arms 4 intersects to determine the position of the steel ball, realizing precise positioning of different impact points on the horizontal plane. The support arm 4 includes an upper support arm 41 and a lower support arm 42. The relative sliding between the upper support arm 41 and the lower support arm 42 enables the overall length of the support arm 4 to be adjusted. In this way, the height of the steel ball drop can be precisely controlled to meet the test requirements.

[0050] During the test, the sample is placed on the horizontal platform 1. The steel ball is adsorbed by electrifying and released by power-off to achieve impact. The crack identification component 3 includes an industrial camera 31 and an image analysis module, which is installed on the support arm 4 through a clamp 43 and can automatically identify the crack characteristics. The auxiliary positioning component 5 includes an infrared laser lamp 51 arranged inside the hollow support arm 4, and the emitted light forms a cross positioning point on the transparent adsorption platform 2. Moving the support arm 4 can adjust the impact point position to meet the 100 mm point spacing required by the standard JG / T 287-2013.

[0051] The support arm 4 adopts a nested structure of the upper support arm 41 and the lower support arm 42, and the lifting is controlled by a motor 7. The horizontal platform 1 is provided with a retaining wall 11 to prevent the steel ball from rolling off.

[0052] In summary, through the flexible support arm design, precise auxiliary positioning component, efficient crack identification component, and safe design details, the present device provides an efficient, accurate, and safe solution for the impact resistance test of thermal insulation decorative panels. It solves the problems of inaccurate positioning and low efficiency in traditional impact tests.
