Description

Technical Field

[0001] The utility model relates to a disposable sealing electronic tag, belonging to the technical field of electronic tags. Background Art

[0002] The existing locks are usually traditional locks or locks combined with RFID electronic tags. The application of these locks is basically based on the one-time use characteristics of the locks, and there is no association between the reading performance of the electronic tag and the effectiveness of the locks. There are certain information loopholes in logistics management or cargo management, and they may be replaced by inferior products or replaced by fake ones.

[0003] The "Shi lock" is a name given to lead seal products within the Ministry of Railways. "Shi" means implementation, "Seal" means seal, "Close", and "Suo" means lock. In fact, the most popular term is: one-time lock. In 2009, the National Standards Committee introduced the international standard ISO17712 and established a national standard, which was officially named box seal. Once this so-called "Shi lock" is used, it cannot be opened. It can only be opened by destroying it, so it is widely used in places such as customs and electricity to prevent others from contacting it for the second time. Each "Shi lock" has a number so that it will not be replaced by others. In short, the function of the "Shi lock" is a one-time lock to prevent others from contacting it.

[0004] RFID: Radio Frequency Identification (RFID) is a type of automatic identification technology that uses radio frequency to perform non-contact two-way data communication and uses radio frequency to read and write recording media (electronic tags or radio frequency cards) to achieve the purpose of identifying targets and exchanging data. Radio frequency identification technology uses radio waves to quickly exchange information and store information without contact, combines wireless communication with data access technology, and then connects to the database system to achieve non-contact two-way communication, thereby achieving the purpose of identification and data exchange, connecting an extremely complex system in series. In the identification system, the reading, writing and communication of electronic tags are achieved through electromagnetic waves. According to the communication distance, it can be divided into near field and far field. For this reason, the data exchange method between the read / write device and the electronic tag is also correspondingly divided into load modulation and backscatter modulation.

[0005] For a passive one-port network containing capacitors, inductors and resistors, its ports may be capacitive, inductive and resistive. When the voltage U and current I at the circuit port are in phase, the circuit is resistive. This is called a resonance phenomenon, and such a circuit is called a resonant circuit. In an AC circuit with resistor R, inductor L and capacitor C, the voltage at both ends of the circuit is generally different from the current phase. If the parameters of the circuit elements (L or C) or the power supply frequency are adjusted, their phases can be made the same, and the entire circuit is purely resistive. The circuit reaching this state is called resonance. In the resonant state, the total impedance of the circuit reaches or nearly reaches the extreme value. The purpose of studying resonance is to understand this objective phenomenon, and to make full use of the characteristics of resonance in science and application technology, while preventing the harm it causes. According to the different circuit connections, there are two types: series resonance and parallel resonance.

[0006] For example, the Chinese patent publication number "CN201063223Y" discloses an electronic sealing lock including an RFID tag antenna and a tag data storage device, which are packaged separately and connected by high-strength wires. It is fast, convenient, low-cost, has a low error rate, and high operating efficiency. It can detect whether the seal is effective in real time online, realize the automation and modernization of sealing inspection, facilitate the analysis of freight accidents, the police's investigation and the division of responsibilities, and facilitate the promotion and application of railway freight car handover inspection. However, there is no correlation between the reading performance of the electronic tag and the effectiveness of the sealing lock. Utility Model Content

[0007] The main purpose of the utility model is to provide a disposable lock electronic tag, which associates the reading performance of the electronic tag with the effectiveness of the lock. During the use of the lock, when the lock is effectively controlled, the electronic tag can be read and identified normally; if the lock is damaged or the lock is opened, the RFID electronic tag will become invalid and cannot be used or read.

DETAILED DESCRIPTION

[0033] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further described below in conjunction with specific implementation methods.

[0034] Example 1

[0035] This embodiment discloses a disposable electronic tag for sealing, including an electronic tag 1 and a sealing buckle structure 3. The electronic tag 1 is a high-frequency electronic tag 1. The specific design is as follows:

[0036] 1. Design of electronic label 1:

[0037] like Figure 1 As shown, the electronic tag 1 includes: a resonant antenna 1-1, an antenna bridge 1-2, a via 1-3, a via 1-4, a first wire end 1-5, a second wire end 1-6, a disconnecting gap 1-7 and a chip 1-8; in order to match the production of a disposable locked electronic tag, the first wire end 1-5 and the second wire end 1-6 are set on the innermost turn of the resonant antenna 1-1, and the disconnecting gap 1-7 disconnects the first wire end 1-5 and the second wire end 1-6 to form a disconnecting structure.

[0038] from Figure 2 It can be seen that the resonant antenna 1-1 and the antenna bridge 1-2 are distributed on both sides of the medium 2, that is, there is a layer of medium 2 between the resonant antenna 1-1 and the antenna bridge 1-2, and it is necessary to connect the two ends of the resonant antenna 1-1 and the two ends corresponding to the antenna bridge 1-2 through the conductive holes 1-3 and the conductive holes 1-4 of the medium 2; the resonant antenna 1-1 is bound with an electronic tag chip 1-8.

[0039] According to the high-frequency antenna design requirements, a resonant antenna 1-1 is manufactured, and after being bound to a chip 1-8, a test is performed to complete the manufacture of an electronic tag 1 (inlay).

[0040] In order to form a fixed disconnection structure inside the antenna, this embodiment considers using laser ablation to burn the innermost coil of the resonant antenna 1-1 into the first wire end 1-5 and the second wire end 1-6 for standby use.

[0041] 2. Design of locking buckle structure 3:

[0042] like Figure 3 As shown, the lock body of the locking buckle structure 3 is divided into a first part 3-1 and a second part 3-2, which are made separately. The first part 3-1 and the second part 3-2 are both made of metal. A raised first wiring contact 3-3 is provided on the surface of the first part 3-1, and a firmly fixed sealing rope 3-5 is provided at one end thereof through machining. The sealing rope 3-5 is made of metal and cannot be pulled out after being fixed in the first part 3-1. The sealing rope 3-5 is made of conductive material, and can be specifically made of steel wire rope.

[0043] A protruding second contact point 3-4 is arranged on the surface of the second component 3-2, and a locking hole 3-6 is arranged inside the second component 3-2, and a reverse tooth clamping structure is arranged inside.

[0044] 3. Processing of locking buckle structure 3

[0045] like Figure 4 As shown, a non-conductive adhesive 3-7 is used to adhere and fix the first component 3-1 and the second component 3-2 together according to certain standards to form a complete sealing buckle structure 3, requiring the first wiring contact 3-3 and the second wiring contact 3-4 to be symmetrically arranged on the same surface with the bonding surface as the symmetry axis. A sealing rope 3-5 is fixed inside the first component 3-1, and a sealing buckle hole 3-6 is arranged inside the second component 3-2, and a reverse tooth clamping device is arranged inside.

[0046] from Figure 5 It can be seen that the first wiring contact 3-3 and the second wiring contact 3-4 are higher than the upper surface of the sealing buckle 3 and have the same height. After the first component 3-1 and the second component 3-2 are firmly bonded with a non-conductive adhesive, the lower surface of the sealing buckle 3 is on the same plane. The end surface of the first component 3-1 with the sealing rope 3-5 and the end surface of the second component 3-2 with the sealing buckle hole 3-6 are on the same side of the sealing buckle 3.

[0047] 4. Injection molding of locking buckle structure 3

[0048] According to the requirements of the electronic tag 1, an injection mold is designed and manufactured, and the shape is injection molded after the locking buckle structure 3 is wrapped with engineering plastic. Figure 6 As shown, in the middle position of the groove 4-1 on the injection molded housing 4, the first wiring contact 3-3 and the second wiring contact 3-4 on the upper surface of the locking buckle structure 3 are exposed on the bottom surface of the groove 4-1 after injection molding, and welding platforms 4-2 are designed around the groove 4-1.

[0049] like Figure 7 As shown, the sealing rope 3-5 and the sealing buckle hole are retained outside the injection molded housing 4. The first wiring contact 3-3 and the second wiring contact 3-4 on the upper surface of the sealing buckle structure 3 are higher than the bottom surface of the groove 4-1 after injection molding and are exposed outside.

[0050] 5. Electronic label 1 assembly

[0051] The shell (injection molded shell 4) of the injection molded locking buckle structure 3 needs to be assembled with the high-frequency electronic tag 1 to complete the production of a one-time locking electronic tag. Figure 8 As shown, the high-frequency electronic tag 1 is placed in the middle position of the groove 4-1 in the injection-molded shell 4. It can be seen that the antenna bridge 1-2 with the chip 1-8 is facing upward, close to the injection-molded cover 4-3; and the resonant antenna 1-1 with the wire terminal 1-57 and the wire terminal 1-6 is facing the lower side.

[0052] like Fig. 9As shown, after the electronic tag 1 is assembled in place, the injection molded cover 4-3 is welded or bonded to the welding platform 4-2 of the injection molded shell 4 of the locking buckle structure 3 using ultrasound or curing glue. Under the pressure of the injection molded cover 4-3, the line terminals 1-5 and 1-6 are respectively in contact with the wiring terminal 3-3 and the wiring terminal 3-4 for conduction.

[0053] 6. Application

[0054] like Fig.10 As shown, when this embodiment is used, it is necessary to wrap the sealing rope 3-5 around the item to be locked, and then pass the sealing rope 3-5 through the sealing buckle hole 3-6 to tighten it. Since a clamping structure is provided in the sealing buckle hole 3-6, the sealing rope 3-5 cannot be pulled out after being tightened. At this time, the sealing rope 3-5 connects the wiring terminal 3-3 of the first part 3-1 of the sealing buckle and the wiring terminal 3-4 on the second part 3-2, that is, the wire end 1-5 and the wire end 1-6 on the resonant antenna 1-1 are connected, so that the resonant antenna 1-1 forms a complete resonant circuit. When there is a resonant electromagnetic wave, the electronic tag 1 can work by induction.

[0055] like Fig.11 As shown, when the sealing rope 3-5 of the disposable electronic tag of this embodiment is cut, the complete circuit of the resonant antenna 1-1 is disconnected, and the electronic tag 1 cannot read normally. The sealing rope 3-5 of the disposable electronic tag of this embodiment cannot be replaced, and the high-frequency electronic tag 1 cannot be replaced or completely removed after being ultrasonically encapsulated or firmly bonded with an adhesive. That is, this structural design method enables the high-frequency electronic tag 1 and the sealing buckle structure 3 to achieve the management purpose of disposable use.
