Abstract
Description
Technical Field
[0001] This utility model relates to the field of testing equipment technology, and in particular to a sample slide of a microwave non-destructive testing system. Background Technology
[0002] In recent years, with more and more researchers devoting their efforts to the field of microwave nondestructive testing (NDT), microwave NDT technology has developed rapidly in the NDT field. Researchers are studying the interaction mechanism between microwaves and the material under test to provide theoretical guidance for microwave NDT research. Different microwave testing methods have been proposed for different industrial application environments. Based on the principles of microwave testing and the object being tested, the basic methods of microwave NDT technology can be divided into interferometry, scattering, reflection, transmission, tomography, and microwave eddy current methods, among others.
[0003] Among them, microwave reflection testing is currently the most widely used microwave testing method in the field of microwave nondestructive testing. Microwave reflection testing works by analyzing the frequency, amplitude, and phase of the received reflected signals when microwaves enter the material being tested, causing varying degrees of reflection on the surface and within the material. The equipment required for microwave reflection testing includes a microwave source, a phase detector, and an antenna. The microwave source generates microwaves, the antenna receives the reflected signals, and sends the signals to the phase detector. The phase detector displays the frequency, amplitude, and phase of the signal to determine the condition of the material.
[0004] However, existing non-destructive microwave testing systems typically only have one slide. The material to be tested is placed on the slide, and after the previous material is tested, it is removed and replaced with a new material for testing. Therefore, it is not possible to test multiple materials continuously, and the efficiency needs to be improved.
[0005] Therefore, it is necessary to provide a sample slide of a microwave nondestructive testing system to solve the above-mentioned technical problems. Utility Model Content
[0006] In order to overcome the shortcomings of the existing technology, this utility model provides a sample slide of a microwave non-destructive testing system that can sequentially test multiple materials, which is beneficial to improving work efficiency.
[0007] To achieve the above objectives, the technical solution adopted by this utility model is as follows:
[0008] The sample slide of the microwave nondestructive testing system includes: a testing stage, a slide mounted on the testing stage, the slide mounted on a track on the top of the testing stage and capable of moving along the track, a first electric push rod mounted on one side of the slide, the first electric push rod being used to drive the slide to move horizontally, multiple testing stations set on the slide, each testing station including multiple square holes evenly opened on the slide, a support column installed in the square hole, and a support plate installed on the top of the support column.
[0009] Preferably, multiple limiting plates are provided on the support column, and the multiple limiting plates are located on the upper and lower sides of the square hole to limit the lifting stroke of the support column.
[0010] Preferably, a second electric push rod is installed at the bottom of the testing platform, and the output shaft of the second electric push rod passes through the testing platform.
[0011] Preferably, a support wheel assembly is installed at the top of the output shaft of the second electric actuator, and the support wheel assembly consists of multiple rollers arranged in a straight line.
[0012] Preferably, a center line is set on the support plate.
[0013] Preferably, positioning lines are set on the testing platform, and multiple pointers are set on the sliding stage, with each pointer corresponding to a testing station.
[0014] Preferably, multiple contacts are fixedly installed on the side of the sliding table, with each contact corresponding to a testing station. A contactor is installed on the top of the testing table, and a warning light is installed on the circuit of the contactor.

[0016] (1) This utility model sets up a testing table and a sliding table, and sets up multiple testing stations on the sliding table. The sliding table is moved by the first electric push rod, so that multiple testing stations can be tested in sequence, which can help improve work efficiency.
[0017] (2) By setting multiple limiting plates on the support column and installing a second electric push rod at the bottom of the testing table, the material to be tested can be lifted to the testing height by the second electric push rod, avoiding interference between other materials to be tested and the material being tested, which is conducive to improving the accuracy of the material testing results;

Detailed Implementation
[0027] The present invention will be further described below with reference to the accompanying drawings and embodiments. The embodiments of the present invention include, but are not limited to, the following embodiments.
[0028] Example 1:
[0029] like Figure 1-7As shown, the sample slide of the microwave non-destructive testing system provided by this utility model includes: a testing stage 1, a sliding stage 2 and a microwave non-destructive testing system 14 mounted on the testing stage 1. The microwave non-destructive testing system 14 is designed using the microwave reflection method and includes at least a microwave source, a phase detector and an antenna (single antenna or dual antenna are both acceptable). Specific wiring connections and usage methods are not detailed here. In summary, the microwave non-destructive testing system 14 can perform non-destructive microwave testing on materials, which is currently the mainstream non-destructive microwave testing method on the market. The sliding stage 2 is mounted on the top track of the testing table 1 and can move along the track. A first electric push rod 3 is installed on one side of the sliding stage 2 and is fixedly connected to the testing table 1 to drive the sliding stage 2 to move. Multiple testing stations are set on the sliding stage 2, each including multiple square holes 4 evenly spaced on the sliding stage 2. Square support columns 5 are installed inside the square holes 4, and support plates 6 are fixedly installed on the top of the support columns 5. The material to be tested is placed on the top of the support plates 6. In use, the material to be tested is placed on each support plate 6 according to the material testing sequence. Then, the first electric push rod 3 drives the sliding stage 2 to move, causing each support plate 6 to stop sequentially in front of the microwave non-destructive testing system 14 for a period of time. During this period, the microwave non-destructive testing system 14 tests the material to be tested on the top of the support plate 6, thus enabling continuous material testing and improving testing efficiency. It is worth noting that the tested material can be replaced during testing, further improving the equipment's working efficiency.
[0030] By setting up a testing table 1 and a sliding table 2, and setting up multiple testing stations on the sliding table 2, and using the first electric push rod 3 to drive the sliding table 2 to move, the multiple testing stations can be tested in sequence, which can help improve work efficiency.
[0031] Example 2:
[0032] like Figure 1-3As shown, in this embodiment, the support column 5 is slidably connected to the square hole 4, and multiple limiting plates 7 are provided on the support column 5. The multiple limiting plates 7 are located on the upper and lower sides of the square hole 4 to limit the lifting stroke of the support column 5. A second electric push rod 8 is installed at the bottom of the detection table 1. The output shaft of the second electric push rod 8 passes through the detection table 1. In use, when the support plate 6 on the sliding table 2 moves to the front of the microwave non-destructive testing system 14, the second electric push rod 8 is activated, causing its output shaft to extend and lift the support column 5, so that the support plate 6 rises until the lower limiting plate 7 contacts the bottom edge of the square hole 4. The support column 5 can no longer rise. At this time, the support plate 6 reaches its highest point, which is the detection height of the material. The material position on other support plates 6 is lower and cannot receive or reflect microwaves. Therefore, it will not cause microwave interference to the material being tested, which is beneficial to improving the detection accuracy of the material. After the test is completed, the output shaft of the second electric push rod 8 retracts, so that the support column 5 falls back to the initial height (the upper limiting plate 7 abuts against the top edge of the square hole 4).
[0033] By setting multiple limiting plates 7 on the support column 5 and installing a second electric push rod 8 at the bottom of the testing table 1, the material to be tested can be lifted to the testing height using the second electric push rod 8, avoiding interference between other materials to be tested and the material being tested, which helps to improve the accuracy of the material testing results.
[0034] Example 3:
[0035] like Figure 6 As shown, a center line 9 is further set on the support plate 6, and the center of the material is preferably placed at the center line 9 to avoid the material being placed off-center.
[0036] By setting a center line 9 on the support plate 6, the placement position of the material to be tested can be determined.
[0037] Example 4:
[0038] like Figure 7 As shown, in this embodiment, a support wheel assembly 15 is installed at the top of the output shaft of the second electric push rod 8. The support wheel assembly 15 consists of multiple rollers arranged in a straight line. The rollers are horizontally installed and can rotate. The top of the support wheel assembly 15 contacts the bottom of the support column 5. When the sliding table 2 moves, the material to be tested passes slowly in front of the microwave non-destructive testing system 14, and the support wheel assembly 5 effectively supports the bottom of the support column 5.
[0039] By installing a support wheel assembly 15 at the top of the output shaft of the second electric push rod 8, the support column 5 can be supported without affecting its horizontal movement.
[0040] Example 5:
[0041] like Figure 1-2As shown, in this embodiment, a positioning line 10 is set on the detection table 1, and multiple pointers 11 are set on the sliding table 2. Each pointer 11 corresponds to a detection station. In use, when the positioning line 10 aligns with a pointer, it means that the detection station corresponding to that pointer 11 has entered the detection range, and the material to be detected at that detection station can be detected. At this time, the second electric push rod 8 can be activated to lift the material to be detected to the detection height.
[0042] By setting a positioning line 10 on the detection table 1 and setting multiple pointers 11 on the sliding table 2, the second electric push rod 8 can be activated conveniently and at the right time.
[0043] Example 6:
[0044] like Figure 1 As shown, multiple contacts 12 are fixedly installed on the side of the sliding table 2, and each contact 12 corresponds to a detection station. A contactor 13 is installed on the top of the detection table 1, and a warning light is installed on the circuit of the contactor 13. When in use, when the detection station on the sliding table 2 moves to the starting position of the detection range, the contact 12 touches the contactor 13, which turns on the warning light circuit and illuminates it. At this time, the second electric push rod 8 should be activated to lift the material to be tested to the detection height.
[0045] By installing multiple contacts 12 on the side of the sliding table 2 and a contactor 13 on the top of the detection table 1, the second electric push rod 8 can be easily and timely activated.
[0046] Working principle: In use, the materials to be tested are placed on each support plate 6 according to the material testing sequence. Then, the sliding table 2 is moved by the first electric push rod 3 so that each support plate 6 is tested in sequence, thereby realizing continuous material testing and improving testing efficiency.
