Description

Technical Field

[0001] The utility model relates to the technical field of tire labels, in particular to a tire RFID label. Background Art

[0002] The tire RFID label is an advanced technical product applied to tires. It consists of a chip and an antenna. By storing key data such as the model, specification, production date, batch number, and manufacturer information of the tire, it plays an important role in the entire life cycle of the tire. In terms of product traceability and management, it can achieve accurate tracking in each stage from production to recycling, facilitating inventory management and optimizing the efficiency of the supply chain. In terms of quality control and safety assurance, it can record production parameters and quality inspection data to prevent the circulation of counterfeit and shoddy products.

[0003] Existing technologies such as the utility model with the publication number of CN218585348U disclose a patch-type RFID electronic label for intelligent tires. This patent uses a patch block. A receiving groove is opened on one side of the patch block. A gasket is pasted on the inner bottom of the receiving groove. A bearing sheet is pasted on one side of the gasket. A top protection sheet is pasted on one side of the bearing sheet. An installation groove is opened on one side of the bearing sheet. An electronic label body is installed inside the installation groove. When in use, the utility model can protect the electronic label body by using the gasket, the top protection sheet, and the patch block, extending the service life of the RFID electronic label to a certain extent. And when the electronic label body is damaged, it can also be replaced, which is very convenient to use, solving the problem that the existing RFID electronic label lacks a protection structure after installation, and it is not convenient to replace the RFID electronic label when it is damaged after long-term use.

[0004] In the process of using RFID labels to manage tires, there is a problem that the structure of existing RFID labels such as the above is relatively simple. During assembly, only the gasket and the bearing sheet are used to protect the chip. Since the environment in which the label is used is relatively harsh, when only the gasket and the bearing sheet are used to protect the chip, the chip is extremely vulnerable to external interference and fails, resulting in accidental damage. Summary of the Utility Model

[0005] The purpose of the utility model is to solve the defect that when only the gasket and the bearing sheet are used to protect the chip in the prior art, the chip is extremely vulnerable to external interference and fails, resulting in accidental damage, and to propose a tire RFID label.

[0006] To achieve the above object, the present utility model adopts the following technical solutions: A tire RFID tag includes a housing and a flexible circuit board. The flexible circuit board is installed inside the housing. An antenna is fixedly connected to the upper surface of the flexible circuit board. A chip is fixedly connected to the upper surface of the antenna. A thermal conductive adhesive is attached to the upper surface of the flexible circuit board. A positioning frame is installed on the inner wall of the housing, and the positioning frame is in contact with the upper surface of the flexible circuit board. Square holes are formed on the surface of the thermal conductive adhesive, and a protective cover is fixedly connected to the inner wall of the square hole. The protective cover is sleeved on the surface of the chip. A cover plate is fixedly connected to the upper surface of the housing, a buffer pad is fixedly connected to the lower surface of the housing, and an adhesive is fixedly connected to the lower surface of the buffer pad.

[0007] Preferably, a protective film is pasted on the lower surface of the adhesive. A handle is provided on the side surface of the protective film. The protective film can protect the pasting part of the tag to reduce the probability of accidental pasting of the pasting part during transportation.

[0008] Preferably, the thermal conductive adhesive is in contact with the upper surface of the antenna. The thermal conductive adhesive can guide the heat of the flexible circuit board to ensure the stability of the flexible circuit board under high temperature conditions.

[0009] Preferably, the protective cover is in contact with the upper surface of the antenna. The protective cover is square, and the inner diameter of the protective cover is larger than the diameter of the chip. The protective cover can support and protect the chip part to reduce the probability of the chip being extruded by external forces.

[0010] Preferably, the cover plate is in contact with the upper surface of the thermal conductive adhesive, the cover plate is in contact with the upper surface of the positioning frame, and the cover plate is in contact with the upper surface of the protective cover. Through the cooperation of the cover plate and the housing, the positioning frame and the thermal conductive adhesive can be stably restricted on the surface of the flexible circuit board to ensure full adhesion of the three.

[0011] Compared with the prior art, the advantages and positive effects of the present utility model are as follows:

[0012] In the present utility model, by providing a thermal conductive adhesive, a positioning frame, a protective cover, and a buffer pad, when encapsulating a chip, the assembled flexible circuit board, antenna, and chip structure are placed into the housing. When the placement is completed, the protective cover is placed directly above the chip, and the positioning frame is snapped into the housing to limit the position of the flexible circuit board. When locking the position of the flexible circuit board, the thermal conductive adhesive is injected into the space formed by the protective cover and the positioning frame. The thermal conductive adhesive seals the flexible circuit board and the antenna and improves the heat dissipation efficiency of the flexible circuit board and the antenna. When the above operations are completed, the cover plate is fixed above the housing to seal the housing. Subsequently, the buffer pad with adhesive can be installed below the housing to complete the overall encapsulation operation of the label. When using the label, the protective film below the adhesive is torn off, the pasting part on the tire is wiped, and after wiping, the adhesive is pasted onto the pasting part of the tire. By providing the thermal conductive adhesive, the positioning frame, the protective cover, and the buffer pad, the protection performance of the label for the internal structure is improved, thereby reducing the problem that the internal structure is vulnerable to external forces due to the lack of protection structure of the label, and further increasing the service life of the label.

[0023] In this embodiment: the heat of the flexible circuit board 2 can be guided through the thermal conductive adhesive 5 to ensure the stability of the flexible circuit board 2 in a high-temperature state.

[0024] Specifically, the protective cover 7 is in contact with the upper surface of the antenna 3. The protective cover 7 is square, and the inner diameter of the protective cover 7 is larger than the diameter of the chip 4. The chip 4 part can be supported and protected through the protective cover 7 to reduce the probability of the chip 4 being extruded by external forces.
