Description

Technical Field

[0001] The utility model relates to the technical field of inspection and detection, in particular to an RFID tag impact resistance testing device. Background Art

[0002] RFID, short for Radio Frequency Identification, is a radio frequency technology and a type of automatic identification technology. RFID technology utilizes radio frequencies to enable contactless data communication between a reader and a tag, enabling target identification and data exchange. Currently, the application of RFID technology in anti-counterfeiting is gaining momentum, with pilot projects underway in pharmaceuticals, high-end watches, premium alcoholic beverages, ID cards, and airline tickets, among other products, embedding RFID chips. However, the application of RFID in anti-counterfeiting is still in its infancy. Whether it is technological breakthroughs or the verification of anti-counterfeiting effectiveness, there is a lack of unified testing and evaluation methods and corresponding testing equipment. This has a significant impact on both manufacturers and users, and the quality of RFID anti-counterfeiting labels on the market varies greatly. Anti-counterfeiting products based on RFID technology often use labels as carriers, which are subject to complex actual application environments and are inevitably subject to wear and tear during use. Therefore, it is necessary to develop an impact testing device that can simulate the actual operating environment of RFID tags. Utility Model Content

[0003] In response to the above technical problems, the present invention provides an RFID tag impact resistance testing device that is easy to operate and efficient to implement, so as to solve the performance research problem of RFID tags. The technical solutions adopted are as follows:

[0004] The specific technical solutions are:

[0005] An RFID tag impact tester includes a motor housing, a transmission gear, a working rod, a workbench, and a striking assembly. The motor housing includes a power supply, a motor, a switch gate, a counter, and a brake device, all of which are connected via circuitry and housed within the housing. The transmission gear is located outside the housing and connected to the inside of the housing via circuitry.

[0006] The outer side of the transmission gear is provided with a plurality of cylindrical columns, and the cylindrical columns are evenly distributed in an annular shape;

[0007] The middle part of the working rod is hinged to the base plate;

[0008] A knocking assembly is provided at the front end of the working rod, and a workbench is provided below the knocking assembly, on which the test piece is placed;

[0009] The rear end of the working rod is inserted between two adjacent cylindrical columns, and the rear end of the working rod is provided with an oblique angle. When the transmission gear rotates, the cylindrical column above the working rod presses down the rear end of the working rod and lifts up the knocking assembly at the front end. Then the cylindrical column above the working rod detaches from the working rod from the oblique angle at the rear end of the working rod, and the knocking assembly falls and knocks on the workbench. The next cylindrical column rotates to the top of the rear end of the working rod as the transmission gear rotates and continues to press down the rear end of the working rod.

[0010] Furthermore, the transmission gear is externally connected to a circular assembly with three cylindrical posts arranged on its outer circumference in an equilateral triangle. When the transmission gear is operating, the circular assembly rotates clockwise, and the three cylindrical posts also rotate continuously by shifting positions. The circular assembly's purpose is to continuously apply striking pressure to the working rod through the shifting positions of the three cylindrical posts.

[0011] Furthermore, the working rod has an inverted U-shaped structure, with the end in contact with the transmission gear tilted upwards and positioned at a distance from the work surface to ensure the circular column of the transmission gear can strike the working rod. This end is secured by two fixed clamps, which are hinged to the working rod with screws. When operating, the working rod exhibits a continuous cycle of tilting-falling-tilting-falling to ensure that it strikes the sample being tested.

[0012] Furthermore, the workbench is placed directly below the front end of the working rod and has a concave structure. Considering the thickness of the RFID tag, there must be a certain concave distance. At the same time, considering that the shape of the RFID tag sample is not standard, the workbench area is large to ensure the accuracy of the test.

[0013] Furthermore, the knocking assembly is placed at the front end of the working rod, just above the center of the workbench, and an empty rod is placed above the knocking assembly for placing weights.

[0014] The RFID tag impact resistance testing device provided by the utility model has a simple principle and is easy to operate, thus filling the technical gaps and method gaps in the field of impact resistance testing of RFID tags. BRIEF DESCRIPTION OF THE DRAWINGS

[0016] Figure 2 It is a three-dimensional structural diagram of the utility model. DETAILED DESCRIPTION

[0017] The specific implementation of the present utility model is described with reference to the embodiments.

[0018] like Figure 1 As shown, an RFID tag impact resistance testing device includes a motor box 10, a transmission gear 5, a working rod 6, a base plate 12, a workbench 7, and a striking assembly 8. The motor box 10 includes a power supply 1, a motor 11, a switch gate 2, a counter 3, and a brake device 4. All components are connected by circuits and placed inside the motor box 10. The transmission gear 5 is placed outside the motor box 10 and is connected to the motor 11 inside the motor box 10 through circuits.

[0019] like Figure 2 As shown, three cylindrical pillars 9 are provided on the outer side of the transmission gear 5, and the cylindrical pillars 9 are evenly distributed in a ring shape.

[0020] The middle part of the working rod 6 is hinged on the base plate 12; the front end of the working rod 6 is provided with a knocking assembly 8, and a workbench 7 is provided under the knocking assembly 8, and the test piece is placed on the workbench 7; the rear end of the working rod 6 is inserted between two adjacent cylindrical columns 9, and the rear end of the working rod 6 is provided with an bevel. When the transmission gear 5 rotates, the cylindrical column 9 above the working rod 6 presses down the rear end of the working rod 6 and lifts the knocking assembly 8 at the front end. Then, the cylindrical column 9 above the working rod 6 detaches from the working rod 6 from the bevel at the rear end of the working rod 6, and the knocking assembly 8 falls and knocks on the workbench 7. The next cylindrical column 9 rotates to the top of the rear end of the working rod 6 as the transmission gear 5 rotates and continues to press down the rear end of the working rod 6.

[0021] The working rod 6 is in an inverted U-shaped structure, and the rear end in contact with the transmission gear 5 is in a tilted structure.

[0022] The workbench 7 is provided with a concave structure.

[0023] Furthermore, the working rod 6 is an inverted U-shaped structure, with the end in contact with the transmission gear 5 tilted and positioned at a distance from the workbench 7 to ensure that the circular column 9 of the transmission gear 5 can strike the working rod 6. This end is hinged to the working rod 6 by two fixed clamps, which are hinged to the working rod 6 by screws. When working, the working rod 6 exhibits a continuous cycle of tilting-falling-tilting-falling to ensure that it strikes the sample to be tested.

[0024] Furthermore, the workbench 7 is placed directly below the front end of the working rod 6 and has a concave structure. Considering the thickness of the RFID tag, there must be a certain concave distance. At the same time, considering that the shape of the RFID tag sample is not standardized, the workbench area is larger to ensure the accuracy of the test.

[0025] Furthermore, the knocking assembly 8 is placed at the front end of the working rod, just above the center of the workbench 7, and an empty rod is placed above the knocking assembly 8 for placing weights.

[0026] The process of use is to lift the working rod 6, place the RFID chip sample to be tested on the workbench 7, just below the knocking component 8. If the sample size is larger than the size of the workbench 7, cut the sample to meet the chip placement position and the size of the workbench 7; if the sample size is smaller than the size of the workbench 7, and the sample is light and easy to deviate during work, you can choose to press the sample with a heavy object.

[0027] Then, the switch gate 2 is opened, and the transmission gear 5 starts to rotate. As the cylindrical column 9 on the transmission gear 5 continuously changes position, it causes the working rod 6 to continuously work in a state of lifting-falling-lifting-falling, and the knocking component 8 continuously knocks the sample to be tested. The number of knocks can be recorded by the counter 3.
