Description

Technical Field

[0001] This utility model relates to the technical field of electromagnetic shielding material testing equipment, and in particular to a ferrite measuring device. Background Technology

[0002] With the widespread adoption of 5G technology and new electronic devices, electromagnetic radiation issues are becoming increasingly prominent. Ferrite absorbing materials, due to their high absorption rate and excellent impedance matching characteristics, have become a core material for reducing electromagnetic interference in microwave anechoic chambers. Microwave anechoic chambers, composed of ferrite absorbing materials and metal shielding, provide an ideal testing environment for wireless devices. However, dimensional deviations in the absorbing patches can lead to increased bonding gaps, severely affecting the material's absorption performance and consequently reducing the overall effectiveness of the microwave anechoic chamber. Therefore, accurately measuring and controlling the geometric parameters of the ferrite material (such as height, porosity, and squareness) is crucial for ensuring its installation quality.

[0003] Currently, the measurement of ferrite absorbing materials mainly relies on two methods: indirectly reflecting the right angle by measuring the side length and diagonal with vernier calipers, or judging the right angle manually by measuring the fitting gap using a right-angle clamp. In practical applications, these existing technologies have the following shortcomings: 1. Low efficiency, unable to simultaneously detect other key parameters (such as height and porosity), making it difficult to meet the demand for efficient multi-parameter detection in large-scale production; 2. Subject to human operational factors, resulting in large measurement errors, and the inability to directly obtain right angle data, leading to insufficient reliability of the results.

[0004] Therefore, how to provide an automated testing device that integrates height, porosity, and perpendicularity measurement functions to improve measurement accuracy, efficiency, and adaptability, thereby ensuring the laying quality of ferrite absorbing materials, has become an urgent technical problem to be solved.

Figure 3 Here is another structural example diagram of the sample fixing mechanism according to this utility model, as shown below. Figure 2 and Figure 3 As shown, in this embodiment, the sample fixing mechanism D includes a sample loading platform D1 and an electromagnet D2 fixedly disposed at the bottom of the sample loading platform D1. The sample loading platform D1 consists of an integrally connected loading part D11 and a loading connecting part D12.

[0033] Figure 4 The diagram below shows an example of the structure of the height and porosity measuring mechanism according to this invention. Figure 4 As shown, in this embodiment, the height and porosity measuring mechanism E includes a rod-shaped measuring loading platform E1, a height measuring component E2 disposed in the middle of the measuring loading platform E1, and a porosity measuring component E3 disposed at the outer end of the measuring loading platform E1.

[0034] Figure 5 The following is a partial cross-sectional view of the height and porosity measuring mechanism according to this utility model. Figure 4 and Figure 5 As shown, as an optional example, in this embodiment, the height measuring component E2 includes a height measuring block E21 and two hydraulic telescopic cylinders E22 fixedly connected to the top of the height measuring block E21, and the porosity measuring component E3 includes a porosity measuring device E31 and a rotary motor E32 fixedly connected to the top of the porosity measuring device E31.

[0035] As an optional example, in this embodiment, a first loading cavity E11 with a downward opening is provided in the middle of the measuring loading platform E1, a second loading cavity E12 with a downward opening is provided at the outer end of the measuring loading platform E1, two first pipeline connection holes E13 are provided on the upper end face of the middle of the measuring loading platform E1, and two through second pipeline connection holes E14 are provided on the side end face of the middle of the measuring loading platform E1.

[0036] The height measuring component E2 has two hydraulic telescopic cylinders E22 built into the first loading cavity E11. The hydraulic telescopic cylinder body E221 is fixedly connected to the top of the first loading cavity E11, and the telescopic end E222 is fixedly connected to the height measuring block E21. The first fluid port E223 of the hydraulic telescopic cylinder matches the first pipeline connection hole E13, and the second fluid port E224 of the hydraulic telescopic cylinder matches the second pipeline connection hole E14. In this embodiment, the height measuring component E2 is hydraulically driven, which can flexibly adjust the downward pressure distance of the height measuring block E21, and is suitable for samples of different thicknesses. In practical applications, when the hydraulic fluid from the external hydraulic pipeline enters the hydraulic telescopic cylinder body E221 through the first fluid port E223, the telescopic end E222 extends downward, causing the height measuring block E21 to move downward. When the hydraulic fluid from the external hydraulic pipeline enters the hydraulic telescopic cylinder body E221 through the second fluid port E224, the telescopic end E222 retracts upward, causing the height measuring block E21 to move upward.

[0037] The rotary motor E32 of the porosity measuring assembly E3 is built into the second loading cavity E12. The porosity measuring device E31 includes, from top to bottom, an integrally connected porosity measuring connection part E311, a measuring frustum part E312, and multiple measuring columns E313 disposed at the bottom of the measuring frustum part E312. Figure 6 This is a structural example diagram of the porosity measuring device according to the present invention. The rotary motor body E321 is fixedly connected to the top of the second loading cavity E12, and the output end E322 of the rotary motor is fixedly connected to the porosity measuring connection part E311 of the porosity measuring device E31. In this embodiment, the porosity measuring component E3 is equipped with measuring columns E313 of different diameters (such as 9.8mm, 10.2mm, etc.), which are automatically switched by the rotary motor E32 to adapt to the measurement of ferrite materials with different pore sizes. In practical applications, when it is necessary to use measuring columns E313 of different diameters for measurement, the rotary motor E32 is started, and the output end E322 of the rotary motor performs a preset rotation to replace the measuring column E313.

[0038] Figure 7 The diagram shows a structural example of the right-angle measuring mechanism according to this utility model. Figure 8 Here is a partial structural example diagram of the right-angle measuring mechanism according to this utility model, as shown in the figure. Figure 7 and Figure 8 As shown, in this embodiment, the right-angle measuring mechanism F includes a right-angle measuring platform F1, a standard right-angle block F2 fixedly installed at the bottom of the right-angle measuring platform F1, and multiple digital dial indicators F3 fixedly installed on one side of the standard right-angle block F2.

[0039] Figure 9 Here is a structural example diagram of the second actuating mechanism according to this utility model, as shown in the figure. Figure 1 and 9 As shown, in this embodiment, the second actuation mechanism H includes, from top to bottom, a hydraulic actuation cylinder H1, a slider H2, and a stepper motor H3 connected in sequence. Specifically, the hydraulic actuation cylinder body H11 is fixedly connected to the upper end of the first guide rail bracket B, the hydraulic actuation cylinder extension end H12 is fixedly connected to the top of the slider H2, the stepper motor body H31 is fixedly connected to the bottom of the slider H2, the stepper motor output end H32 is fixedly connected to the upper part of the inner end of the measuring loading platform E1, and a slide groove H21 is provided on one side of the slider H2, which matches the first guide rail bracket B. When the hydraulic actuation cylinder extension end H12 of the hydraulic actuation cylinder H1 extends downward or retracts, it causes the slide groove H21 to move downward or upward along the first guide rail bracket B. When the stepper motor H3 is started, the stepper motor output end H32 rotates and drives the aperture measuring component E3 connected to it. In practical applications, multiple hydraulic actuation cylinders H1 can be provided to further improve the smooth control of the overall device's movement. In this embodiment, the automatic lifting and rotation of the measuring mechanism is achieved through a hydraulic cylinder H1 and a stepper motor H3, reducing manual intervention.

[0040] It should be noted that in this embodiment, the first action mechanism G, the third action mechanism I, and the second action mechanism H have the same structural composition.

[0041] The first actuating mechanism G is symmetrically positioned below the second actuating mechanism H. Specifically, the hydraulic end of the first actuating mechanism G is fixedly connected to the lower end of the first guide rail bracket B, and the motor end of the first actuating mechanism G is fixedly connected to the sample loading platform D1 of the sample fixing mechanism D, specifically, to the outer end of the loading connection part D12. Similar to the operating principle of the second actuating mechanism H, when the hydraulic end of the first actuating mechanism G is activated, the sample fixing mechanism D can move upwards or downwards along the first guide rail bracket B; when the motor end of the first actuating mechanism G is activated, the sample fixing mechanism D can rotate.

[0042] The hydraulic end of the third actuating mechanism I is fixedly connected to the upper end of the second guide rail bracket C, and the motor end of the third actuating mechanism I is fixedly connected to the right-angle measuring platform F1 of the right-angle measuring mechanism F. Similar to the operating principle of the second actuating mechanism H, when the hydraulic end of the third actuating mechanism I is activated, the right-angle measuring mechanism F can move upward or downward along the second guide rail bracket C; when the motor end of the third actuating mechanism I is activated, the right-angle measuring mechanism F can rotate.

[0043] For example, such as Figures 1 to 9 As shown, the application principle of the ferrite measuring device in this embodiment is as follows:

[0044] The ferrite sample to be measured is placed on the sample loading platform D1 of the sample fixing mechanism D.

[0045] The hydraulic and motor ends of the first action mechanism G are activated, causing the sample fixing mechanism D to move and rotate to a suitable position at a height below the porosity measuring mechanism E. The rotary motor E32 of the porosity measuring assembly E3 is activated, so that one measuring column E313 (9.8 mm in diameter) of the porosity measuring instrument E31 is perpendicular to the sample loading platform D1 of the sample fixing mechanism D.

[0046] The hydraulic end of the second action mechanism H is activated, causing the height and porosity measuring mechanism E to move downwards. If the measuring column E313 (diameter 9.8mm) can pass through the pore diameter of the ferrite sample, the hydraulic end of the second action mechanism H is activated, causing the height and porosity measuring mechanism E to move upwards. The rotary motor E32 of the porosity measuring assembly E3 is activated, making the other measuring column E313 (diameter 10.2mm) of the porosity measuring device E31 perpendicular to the sample loading platform D1 of the sample fixing mechanism D. The hydraulic end of the second action mechanism H is activated, causing the height and porosity measuring mechanism E to move downwards. If the measuring column E313 (diameter 10.2mm) cannot pass through the pore diameter of the ferrite sample, the pore diameter of the ferrite is deemed to be qualified.

[0047] By activating the hydraulic end of the second action mechanism H, the height and porosity measuring mechanism E is positioned at a preset height in the longitudinal direction. The hydraulic telescopic cylinder E22 of the height measuring component E2 is then activated, causing the height measuring block E21 to move downwards. When the height measuring block E21 contacts the upper surface of the ferrite, the thickness of the ferrite is calculated based on the preset height of the height and porosity measuring mechanism E in the longitudinal direction and the downward distance of the height measuring block E21. If the ferrite thickness is within acceptable limits, the digital dial indicator F3 is zeroed. By activating the hydraulic and motor ends of the third action mechanism I, the right-angle measuring mechanism F is moved and rotated to the test position. Specifically, the right-angle measuring platform F1 is moved to one end of the ferrite sample on the sample loading platform D1, ensuring that the standard right-angle block F2 is in close contact with the edge of the ferrite sample. The reading of the digital dial indicator F3 is used to determine whether the right-angle dimension of the ferrite product meets the preset requirements.

[0048] In practical applications, this embodiment effectively solves the problems of low efficiency, large errors, and limited functionality of traditional measurement methods through multi-parameter integrated measurement, high-precision automated control, and modular structural design. It can complete the detection of height, porosity, and squareness on the same equipment simultaneously, significantly reducing measurement time and meeting the needs of large-scale production.

Therefore, the protection scope of this utility model should be determined by the scope of the claims.
