[0020] To further illustrate each embodiment, the present invention provides drawings. These drawings are part of the disclosure of the present invention, which are mainly used to illustrate the embodiments and can be used in conjunction with the relevant descriptions in the specification to explain the operating principles of the embodiments. With reference to these contents, ordinary technicians in this field should be able to understand other possible implementations and advantages of the present invention.

[0021] The utility model is now further described in conjunction with the accompanying drawings and specific implementation methods.

[0022] The utility model embodiment provides an anti-disassembly traceability electronic tag, such as Figure 1-6 As shown, it includes: a chip base 1, a chip 2 and an antenna base 3.

[0023] like Figure 1 and Figure 2 As shown, the chip 2 is soldered to the chip pad 12 on the first surface 11 of the chip base 1, and is connected to the RFID radiation antenna 31 on the antenna base 3 through the soldering points corresponding to the chip pad 12 on the second surface 13 of the chip base 1. The chip base 1 includes a conducting circuit 14, and the conducting circuit 14 forms two soldering points 15 on the second surface 13 of the chip base 1. Figure 3 As shown, the first surface 11 of the chip base 1 is protected by the sealing glue 4. In this embodiment, the chip base 1 adopts a PCB board, and the two sides of the PCB board serve as the first surface 11 and the second surface 13 of the chip base 1 respectively.

[0024] like Figure 4As shown, the antenna base 3 includes an RFID radiation antenna 31, a traceability code 32 and an anti-tampering lead circuit 33, wherein: the anti-tampering lead circuit 33 includes a first lead circuit 331 and a second lead circuit 332, one end of the first lead circuit 331 and the second lead circuit 332 is set as a solder joint 16, and is respectively connected to two solder joints 15 corresponding to the conduction circuit 14 in the chip base 1, and the other ends of the first lead circuit 331 and the second lead circuit 332 are respectively connected to two breakpoints formed after a path in the device power supply circuit is disconnected. The RFID radiation antenna 31 is the radiation antenna originally required for the RFID tag. The traceability code 32 can use EPC code or TID code. By matching and binding the traceability code 32 with the TID code or EPC code in the RFID chip, the identity information of the product can be recorded. The traceability code 32 can be generated by laser printing.

[0025] In the above-mentioned anti-tampering traceability electronic tag, the chip base 1 is soldered to the RFID radiation antenna 31 and the anti-tampering lead circuit 33 by soldering. The conductive circuit 14 in the chip base 1 makes the originally disconnected part in the device power supply circuit reopened, and makes the chip 2 contact with the RFID radiation antenna 31 to form a complete RFID tag. Figure 5 The figure shows the corresponding positions of the chip base and the antenna base before installation. Figure 6 The schematic diagram shown is a schematic diagram after the chip base is installed on the antenna base.

[0026] In the normal use of the above-mentioned anti-disassembly traceability electronic tag, the information recorded in the RFID tag chip can be read at a long distance to achieve the purpose of tracing the source of the product through the tag information. Since the first side 11 of the chip base 1 is sealed with glue for protection, it can protect the user from removing only the chip 2. When the chip base 1 is maliciously dismantled, due to the presence of the conductive circuit 14 in the chip base 1, the power supply circuit of the device is disconnected, which causes the device to fail to work normally, thereby achieving the anti-disassembly purpose of the electronic tag. In addition, when the chip base 1 is maliciously dismantled, the product information can be queried through the traceability code 32 on the antenna base 3 to achieve the purpose of anti-counterfeiting and traceability.

[0027] In this embodiment, it is preferred that chip 2 is an ultra-high frequency chip, so that the long reading distance of the ultra-high frequency chip can be used to efficiently count and search for products.

[0028] The embodiment of the utility model overcomes the defect in the traditional solution that the RFID chip cannot be traced after being disassembled.

[0029] Although the present invention has been specifically demonstrated and described in conjunction with the preferred embodiments, those skilled in the art should understand that various changes may be made to the present invention in form and detail without departing from the spirit and scope of the present invention as defined in the appended claims, all of which are within the scope of protection of the present invention.
