DETAILED DESCRIPTION
[0027] The technical solutions in the embodiments of the utility model will be clearly and completely described below with reference to the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of the utility model.
[0028] As Figures 1-8As shown, an anti-tampering RFID electronic tag includes a protective shell 1. The protective shell 1 has an internal cavity, into which a PET substrate 2 is inserted. An RFID tag 3 is fixedly mounted on the surface of the PET substrate 2. A protective film assembly 4 is fixedly mounted on one side of the PET substrate 2. A sealing strip 5 is fixedly mounted on one end of the PET substrate 2. Insertion strips 6 are fixedly mounted on the top and bottom of one side of the sealing strip 5. A limiting groove is formed on one side of the top surface of the insertion strip 6. An anti-tampering component 7 is fixedly mounted inside the limiting groove. By setting the insertion strip 6 and the anti-tampering component 7, the PET substrate 2 is inserted into the cavity of the protective shell 1. At this time, the insertion strip 6 is inserted into the insertion groove. The edge of the insertion groove presses the blocking block 704 to press it into the limiting groove. After the insertion strip 6 is inserted into place, the spring 701 pops the blocking block 704 out of the limiting groove, so that the blocking block 704 is stuck on the side wall of the insertion groove. This achieves the effect that the RFID tag 3 cannot be disassembled after installation, thus avoiding loss or reuse.
[0029] The protective housing 1 has insertion slots on the top and bottom of one side. A pressure sensor 8 is fixedly installed on one side of the inner wall of the insertion slot. A warning component 9 is electrically connected to one side of the pressure sensor 8. With the arrangement of the pressure sensor 8, the warning component 9 and the protective film group 4, when a person pulls the tag from the installation position, the blocking block 704 will squeeze the pressure sensor 8, and then the PLC controller 901 will control the alarm 902 to sound an alarm, reminding the staff to avoid the tag being removed. The TPU buffer film 402 can buffer minor impacts. When the protective housing 1 is damaged from the front, the borosilicate glass ceramic composite film 401 will shatter. The shattering will extend to the etched antenna of the RFID tag 3, making the RFID tag 3 permanently invalid and preventing reuse.
[0030] like Figure 2 As shown, the protective film assembly 4 includes a borosilicate glass-ceramic composite film 401 and a TPU buffer film 402. The borosilicate glass-ceramic composite film 401 is fixedly disposed on one side of the PET substrate 2, and the TPU buffer film 402 is fixedly disposed on one side of the borosilicate glass-ceramic composite film 401.
[0031] The protective film group 4 serves to protect the RFID tag 3. When it is damaged externally, the RFID tag 3 will break, thus preventing reuse.
[0032] like Figure 4 and Figure 8 As shown, the anti-disassembly component 7 includes a spring 701, an outer tube 702, an inner tube 703, and a blocking block 704. The spring 701 is fixedly disposed inside the limiting groove, the outer tube 702 is sleeved inside the spring 701, the inner tube 703 is slidably disposed inside the outer tube 702, and the blocking block 704 is fixedly disposed on the top of the inner tube 703.
[0033] The anti-disassembly component 7 ensures that the RFID tag 3 cannot be removed after installation.
[0034] like Figure 4 As shown, the bottom of the outer tube 702 is fixedly installed on the inner bottom wall of the limiting groove, and the blocking block 704 is slidably connected to the limiting groove.
[0035] The limiting groove serves to limit the movement of the blocking block 704.
[0036] like Figure 6 and Figure 7 As shown, the warning component 9 includes a PLC controller 901 and an alarm 902. The PLC controller 901 is electrically connected to one side of the pressure sensor 8, and one side of the alarm 902 is electrically connected to the PLC controller 901. Both the PLC controller 901 and the alarm 902 are fixedly mounted on the edge of the protective housing 1.
[0037] By setting the warning component 9, when a person pulls the label from the installation position, the blocking block 704 will squeeze the pressure sensor 8, which will then control the alarm 902 through the PLC controller 901 to sound an alarm, reminding the staff to avoid the label being removed.
[0038] like Figure 5 As shown, the insertion slot is adapted to the insertion strip 6, and a PET film 10 is fixedly provided on the surface of the protective shell 1;
[0039] The insertion slot facilitates the insertion of the connector strip 6.
[0040] like Figure 7 As shown, there are two sets of connector strips 6 and anti-disassembly components 7, and the two sets of connector strips 6 and anti-disassembly components 7 are arranged symmetrically along the axial direction.
[0041] The anti-disassembly component 7 serves to secure the sealing strip 5 and prevent the RFID tag 3 from being disassembled.
[0042] The working principle of this utility model is as follows: The PET substrate 2 is inserted into the cavity of the protective shell 1. At this time, the insertion strip 6 is inserted into the insertion slot. The edge of the insertion slot presses the blocking block 704 to press it into the limiting slot. After the insertion strip 6 is inserted into place, the spring 701 pops the blocking block 704 out of the limiting slot, so that the blocking block 704 is stuck on the side wall of the insertion slot. After the RFID tag 3 is installed, it cannot be disassembled to avoid loss or reuse.
[0043] When personnel pull the label from the installation position, the blocking block 704 will squeeze the pressure sensor 8, which will then control the alarm 902 through the PLC controller 901 to sound an alarm, reminding the staff to prevent the label from being removed.
[0044] The TPU buffer film 402 can buffer minor impacts. When the protective shell 1 is damaged from the front, the borosilicate glass ceramic composite film 401 will shatter. The shattering will extend to the etched antenna of the RFID tag 3, causing the RFID tag 3 to become permanently disabled and preventing reuse.
[0045] It should be noted that the device structure and accompanying drawings of this utility model mainly describe the principle of this utility model. In terms of the technical aspects of this design principle, the setting of the power mechanism, power supply system and control system of the device is not fully described.
