For those of ordinary skill in the art, the specific meanings of the above terms in the present invention can be understood according to specific situations.

[0044] Embodiment 1

[0045] In Embodiment 1 of the present invention, a manufacturing method of a cable temperature-measuring electronic tag is provided. The cable temperature-measuring electronic tag provided in Embodiment 1 of the present invention belongs to a single / monomeric electronic tag, and the shape of the tag can be similar to the shape of a band-aid and is used alone as an RFID passive electronic tag. Moreover, the cable temperature-measuring electronic tag in the embodiment of the present invention has the function of anti-metal interference. When it is used, it is attached to the cable and can timely monitor the change of the cable temperature.

[0046] Refer to Figures 1 to 3 As shown, the method may include the following steps:

[0047] Step S111: Bond the RFID chip 211 on the flexible printed circuit board 212 to form the FPC antenna 21, perform a dry-to-wet treatment on the FPC antenna 21, and die-cut the FPC antenna 21 after the dry-to-wet treatment.

[0048] In this embodiment, the flexible printed circuit board serves as a cable. After bonding the RFID chip, it can supply power to the RFID chip and transmit data. The dry-to-wet treatment is to avoid the electronic tag produced from foaming or being unevenly pasted during use. For example, when it is attached to a cable or electromechanical equipment, it adsorbs the moisture on the adsorption surface, resulting in the tag foaming and being unevenly pasted. Die-cutting means die-cutting the required size according to the specified specifications of the electronic tag and removing the excess waste.

[0049] Step S112: Punch the polyimide polymer material layer 22 to obtain a receiving hole 221 for accommodating the RFID chip 211.

[0050] Since the RFID chip has a certain thickness, when pasted together, in order to avoid the overall appearance of the electronic tag being more flat and to effectively protect the RFID chip better. Therefore, in this step, the polyimide polymer material layer needs to be punched with a hole of the size of the chip to obtain a receiving hole for accommodating the RFID chip. The punching technology can be the existing technology in die-cutting and punching, which will not be elaborated in this embodiment.

[0051] It should be noted here that the above polyimide polymer material layer in this embodiment is composed of two layers of polyimide polymer materials laminated together. Therefore, before punching, the single-layer polyimide polymer materials need to be laminated into a double layer.

[0052] Step S113: Laminate the punched polyimide polymer material layer 22 on the aluminum foil 24 after applying the adhesive 23. One end of the aluminum foil 24 is bent so that when the FPC antenna 21 is attached to the polyimide polymer material layer 22, there is a gap with a preset width between the end of the aluminum foil 24 and the end of the FPC antenna 21.

[0053] The application environment of the cable temperature-measuring electronic tag is very complex, so the tag must be designed to be metal-resistant. As is well known, metal has a great influence on radio frequency signals (because radio frequency signals are electromagnetic signals, and metal has an adsorption effect on electromagnetic signals). In this environment, metal-resistant tags were born, and their working principle mainly relies on the medium that isolates from the metal (to increase the distance between the metal surface and the tag), and at the same time regards the metal as a reflecting surface to improve the characteristics of the tag on the metal. The metal-resistant tag is an electronic tag encapsulated with a special anti-magnetic wave-absorbing material, which technically solves the problem that the electronic tag cannot be attached to the metal surface for use. Therefore, in the embodiment of the present invention, aluminum foil is used as the anti-magnetic wave-absorbing material.

[0054] It should be noted here that the aluminum foil needs to be bent at the end. The radio frequency signal between the electronic tag and the reader is spatially (contactless) coupled through the coupling element. In the coupling channel, according to the timing relationship, the energy transfer and data exchange are realized; there are two types of their coupling.

[0055] 1) Electromagnetic backscatter coupling: The radar principle model, the electromagnetic wave emitted hits the target and then reflects, and at the same time carries back the target information, based on the spatial propagation law of the electromagnetic wave.

[0056] 2) Inductive coupling: Transformer model, which realizes coupling through a high-frequency alternating magnetic field in space and is based on the law of electromagnetic induction. Scope of application: The inductive coupling method is generally suitable for short-range radio frequency identification systems operating at medium and low frequencies. Typical operating frequencies are: 125 kHz, 225 kHz, and 13.56 MHz. The identification operating distance is less than 1 m, and the typical operating distance is 10 - 20 cm.

[0057] 3) Electromagnetic backscatter coupling method: Generally suitable for long-range radio frequency identification systems operating at high frequencies and microwaves. Typical operating frequencies are: 433 MHz, 915 MHz, 2.45 GHz, 5.8 GHz. The identification operating distance is greater than 1 m, and the typical operating distance is 3 - 10 m.

[0058] The metal-resistant cable fixed-size temperature-measuring tag uses the electromagnetic backscatter coupling method. The aluminum foil needs to be bent and bent to the plane where the FPC antenna is located, and a certain distance is maintained between the aluminum foil and the FPC antenna to form a slot coupling structure, so as to cope with complex environments.

[0059] Step S114: Laminate the FPC antenna 21 on the polyimide polymer material layer 22 after applying glue.

[0060] In the method for manufacturing the above cable temperature-measuring electronic tag provided in the embodiment of the present invention, the process flow can be applied to large-scale production and manufacturing, and an electronic tag suitable for complex environments can be prepared. The prepared electronic tag plays a leading role in the whole-life management of power equipment, especially for better services such as equipment asset inventory, quality control, and traceability.

[0061] For example, during the cable monitoring process, a special temperature-measuring tool is required to align with the outer sheath of the cable to read the temperature. In the embodiment of the present invention, by integrating a temperature-measuring sensor module in the RFID chip, automatic temperature measurement of the cable can be realized, and the operating temperature of the cable can be conveniently obtained through a reader, making the electronic tag more suitable for the application scenario of cable identification.

[0062] In a more specific embodiment, refer to Figure 4 and Figure 2 As shown, the method may specifically include the following steps:

[0063] Step S411: Bond the RFID chip 211 on the flexible printed circuit board 212 to form the FPC antenna 21, perform a dry-to-wet treatment on the FPC antenna 21, and die-cut the FPC antenna 21 after the dry-to-wet treatment.

[0064] This step can refer to the above step S111 and will not be elaborated here. Of course, before this, it is necessary to inspect the incoming FPC materials, that is, determine the quantity and batch number of the FPC antennas.

[0065] Step S412: Detect the FPC antenna 21 and reject unqualified die-cut products.

[0066] Refer to Figure 3 As shown, the detection method may include sampling inspection, visual inspection, etc. The embodiments of the present invention do not specifically limit this detection method.

[0067] Step S413: Rewrite and initialize the storage area of the RFID chip 211.

[0068] Since the RFID chip contains multiple storable areas, it is necessary to expand the storage of the EPC area, that is, it is necessary to modify the parameters of the PC bits. For example, rewrite the PC bit 3000 in the RFID chip to 4000 and record the TID.

[0069] Step S414: Detect the FPC antenna 21 again and reject unqualified products.

[0070] Step S415: Laminate the identification information of the cable temperature measurement electronic tag on the surface of the FPC antenna 21.

[0071] After initialization, laminate the surface material on the surface of the FPC antenna. The surface material may include company information, product information, etc., which is convenient for subsequent product production.

[0072] Step S416: Punch the polyimide polymer material layer 22 to obtain a receiving hole 221 for receiving the RFID chip 211.

[0073] This step may refer to the above step S112 and will not be elaborated here.

[0074] It should be noted that the above polyimide polymer material layer is composed of two layers of polyimide polymer materials laminated together. The raw material of the polyimide polymer material is soft and thin, and it needs to be laminated into the required shape and size according to requirements.

[0075] Step S417: Laminate the punched polyimide polymer material layer 22 on the aluminum foil 24 after applying glue 23.

[0076] Step S418: Laminate the thermoplastic polyester layer 26 on the FPC antenna 21 on the side away from the RFID chip 211.

[0077] The thermoplastic polyester layer may be provided with the identity identification of the electronic tag. For example, the manufacturer identification and the identity (ID) information of the electronic tag may be printed on the side of the thermoplastic polyester layer away from the RFID chip. The embodiments of the present invention do not specifically limit this. Of course, the thermoplastic polyester layer can also play a buffering role for the above electronic tag and further protect the FPC antenna inside the tag.

[0078] Step S419: Apply adhesive 23 on the side of the aluminum foil 24 facing away from the bending direction, and laminate the release film 25.

[0079] For the semi-finished product with the aluminum foil laminated, adhesive needs to be applied at the bottom of the aluminum foil. After the product is formed, it can be pasted on the surface of an object. Moreover, the surface of the release film undergoes a special process, making it easy to peel off the adhesive pasted on it.

[0080] Step S420: Laminate the FPC antenna 21 on the polyimide polymer material layer 22 after applying the adhesive.

[0081] In this step, the FPC antenna 21 is laminated on the polyimide polymer material layer 22 after applying the adhesive. During the lamination process, the position of the accommodation hole punched in the polyimide polymer material should correspond to the lamination of the RFID chip without deviation. Otherwise, the RFID chip will not be protected and the performance of the product is likely to deviate due to external pressure.

[0082] Step S421: Die-cut the finished cable temperature measurement electronic tag after laminating the FPC antenna 21 on the polyimide polymer material layer 22 after applying the adhesive 23.

[0083] In this step, the laminated semi-finished product is die-cut to meet the requirements of the size, ultimately meeting the requirements of the finished product.

[0084] Of course, the embodiment of the present invention may also include consistency inspection, appearance inspection, etc. Before leaving the warehouse, consistency detection of the product performance needs to be carried out to ensure that the product performance will not be uneven. Then, after the cable temperature measurement electronic tag is manufactured, it is placed in the packing box according to the packaging requirements.

[0085] Based on the same inventive concept, the embodiment of the present invention also provides an application of the cable temperature measurement electronic tag prepared by the manufacturing method of the above cable temperature measurement electronic tag in cable identification.

[0086] Embodiment 2

[0087] Embodiment 2 of the present invention provides a manufacturing method of a roll-type electronic tag. Referring to Figure 5 as shown, the method may include the following steps:

[0088] Step S511: Bond the RFID chip on the flexible printed circuit board to form an FPC antenna, perform a dry-to-wet treatment on the FPC antenna, and die-cut the FPC antenna after the dry-to-wet treatment.

[0089] Step S512: Punch the polyimide polymer material layer to obtain accommodation holes for accommodating the RFID chip.

[0090] Step S513: Laminate the punched polyimide polymer material layer onto the aluminized foil after applying adhesive. Bend one end of the aluminized foil so that when the FPC antenna is attached to the polyimide polymer material layer, there is a gap with a preset width between the end of the aluminized foil and the end of the FPC antenna.

[0091] Step S514: Laminate the FPC antenna onto the polyimide polymer material layer after applying adhesive.

[0092] Step S515: Apply adhesive to the side of the aluminized foil of multiple electronic tags that faces away from the bending direction, laminate a release film, and wind it into a roll of electronic tags.

[0093] In this step, during the product manufacturing process, it needs to be laminated onto the release film to facilitate winding for subsequent process manufacturing, and preparing the roll of electronic tags is convenient for industrial labeling. For example, using labeling machine equipment to quickly attach the roll of electronic tags to the cable.

[0094] In an optional embodiment, after laminating the FPC antenna onto the polyimide polymer material layer after applying adhesive, it may further include: laminating a thermoplastic polyester layer onto the FPC antenna on the side facing away from the RFID chip.

[0095] Based on the same inventive concept, the embodiments of the present invention also provide an application of the roll of electronic tags prepared by the manufacturing method of the above roll of electronic tags in cable identification.

[0096] Obviously, those skilled in the art can make various modifications and variations to the present invention without departing from the spirit and scope of the present invention. The present disclosure is not limited to the exact structure described above and shown in the drawings, and various modifications and changes can be made without departing from its scope. The scope of the present disclosure is only limited by the appended claims.
