Description

Technical Field

[0001] The invention belongs to the technical field of electronic tag antennas, and in particular relates to a ceramic electronic tag antenna rapid test frequency modulation device and a ceramic electronic tag antenna rapid test frequency modulation method. Background Art

[0002] At present, most of the electronic tag testing tools use the inductive testing method, that is, the non-contact testing method. The antenna is placed flat under the horizontally erected metal pole. The distance between the antenna and the horizontal metal pole depends on the size of the antenna itself. The larger the antenna size, the farther it is from the metal pole, and the smaller the antenna size, the closer it is to the metal pole. The testing principle is: the horizontal metal pole has a certain distance from the metal reflector in the vertical direction. The general height is 2 to 5 times the thickness of the antenna being tested. The horizontal metal pole is connected to the test port of the network analyzer through a coaxial connector. The generated induced current couples and feeds the ceramic electronic tag antenna. The tag antenna is excited by the induced current to resonate. The resonant frequency of the electronic tag antenna can be intuitively seen through the network analyzer. The resonant frequency is adjusted by adjusting the size of the silver layer area on a certain surface of the tag antenna to achieve the required resonant frequency, that is, the operating frequency.

[0003] However, the disadvantages of this test fixture are: 1. The antenna under test needs to be placed horizontally and in close contact with the metal reflector, which can easily cause scratches on the antenna surface and wear on the reflector surface;

[0004] 2. If tiny impurities such as dust or hair fibers fall between the surface of the metal reflector and the surface of the antenna under test, it will cause the test frequency to shift, and a slight deviation in the angle and position of the antenna will cause a large frequency test error;

[0005] 3. When the test frequency deviates from the target frequency, an electric grinder is required to trim the physical dimensions of the surface electrode. A common problem is that each antenna needs to be picked up and put down for repeated debugging 3 to 5 times on average before the frequency can be adjusted to the right position. Each test requires the antenna to be placed horizontally and in good contact with the reflector. In actual operation, friction will occur between the antenna surface and the reflector. The more debugging times, the lower the production efficiency, the more scratches will be caused to the contact surface between the antenna and the reflector, and the service life of the reflector will be reduced.

[0006] 4. Ceramic electronic tags tend to be miniaturized. The antenna is small in size, which makes it inconvenient to manually pick up and place the antenna. The antenna cannot be fixed stably, and the defective rate during debugging will also increase, affecting production efficiency. Summary of the invention

[0007] The main purpose of the present invention is to provide a ceramic electronic tag antenna rapid test frequency modulation device and method, which is contacted by a retractable probe, has the characteristics of stable electrical performance and little environmental influence, and can test the frequency modulation online (that is, the antenna under test is stably fixed on an insulating test platform, exposing the electrode surface that needs to be debugged, and the operator can debug while performing online debugging according to the change of the resonant frequency. After the frequency is in place, the antenna under test can be taken out of the operating platform).

[0008] Another object of the present invention is to provide a ceramic electronic tag antenna rapid test frequency modulation device and method thereof, the antenna to be tested is placed once, and the contact surface with the antenna is made of insulating plastic material, which has little impact on the surface appearance of the antenna.

[0009] To achieve the above purpose, the present invention mainly provides a method for quickly testing a ceramic electronic tag antenna and frequency modulation, which is used for quickly testing a ceramic electronic tag antenna and includes the following steps:

[0011] Step S2: The antenna under test (ceramic electronic tag antenna) is horizontally placed between the coaxial connector and the insulating fixing rod, and the electrode surface of the antenna under test faces upward;

[0012] Step S3: The foot-operated pneumatic switch is released to release the compressed air in the cylinder through the air outlet pipe, so that the cylinder drives the insulating fixing rod to extend and pushes the antenna under test to the insulating column plane of the coaxial connector to be pressed and fixed (the purpose is to reduce scratches on the surface of the antenna under test and to increase the strength of fixing the antenna under test);

[0013] Step S4: a (retractable) probe of a coaxial connector fixed to the insulation test platform contacts the antenna under test and is pushed to the inside of the coaxial connector by the antenna under test;

[0014] Step S5: The network analyzer electrically connected to the coaxial connector displays the resonant frequency characteristics of the antenna under test.

[0015] As a further preferred technical solution of the above technical solution, step S5 is specifically implemented as the following steps:

[0016] Step S5.1: If the network analyzer shows that the resonant frequency characteristic of the antenna under test is 0K, the foot-operated pneumatic switch is pressed to remove the antenna under test;

[0017] Step S5.2: If the network analyzer shows that the resonant frequency characteristic of the antenna under test is NG, there is no need to remove the antenna under test and it can be debugged directly through the electric grinding head until the network analyzer shows that the resonant frequency characteristic of the antenna under test is 0K, and then the foot-operated pneumatic switch is pressed to remove the antenna under test.
