Embodiment 1

[0041] Example 1, such as Figure 1 to Figure 3 As shown, the RFID tire electronic tag mainly includes:

[0042] a radio frequency module 1 arranged on a substrate 3,

[0043] On both sides of the radio frequency module 1, a group of spring-type antennas 2 extending in a spiral shape are symmetrically connected, and the spring-type antenna 2 is a steel wire coated with brass on the outer layer.

[0044] At the end of the spring antenna 2 connected to the radio frequency module 1, springs with two pitches are fixed together.

[0045] At both ends of the radio frequency module 1 connected to the spring antenna 2, four pins 11 connected to the PAD bonding points inside the radio frequency module 1 are respectively provided.

[0046] like figure 2 As shown, a copper clad layer 31 is provided on one side of the substrate 3, and the thickness of the copper clad layer 31 is 2 oz.

[0047] A through hole 32 is provided on the copper clad layer 31 , and the through hole 32 is cove...

Abstract

The invention relates to an RFID (Radio Frequency Identification Device) tire electronic tag and a manufacturing method thereof and provides an electronic tag structure adopting spring type antennas. In the invention, the robustness of the RFID tire electronic tag is improved from the aspects of connecting structures of all parts and processing methods so as to guarantee that the electronic tag can bear high temperature, various stresses and flexure deformation in the processing and using processes of a tire, and moreover, the electronic tag cannot be delaminated from the tire during the whole life cycle of the tire so as to ensure that the electronic tag can normally communicate with external reading-writing equipment in the whole life cycle of the tire. The RFID tire electronic tag mainly comprises a substrate with a special shape, a radio frequency module mounted on the substrate and a pair of spirally extended spring antennas. The specially processed substrate, the radio frequencymodule and the antennas are welded together through a certain processing process, thus the electronic tag can be completely applied to the total life cycle of the tire.

Description

technical field [0001] The invention aims at improving the robustness of RFID tire electronic tags to adapt to the tire processing process and use environment, and belongs to the fields of rubber machinery and electronic information. Background technique [0002] With the innovation of tire manufacturing technology, especially the introduction and combination of computer network management technology of automobile manufacturing and sales units, RFID electronic tags are implanted into tires as data information carriers and feedback terminals to realize the informatization of the whole life cycle of tires Management is no longer just a technical concept. [0003] The RFID electronic tag implanted in the tire essentially plays the role of "electronic ID card", that is, the tires with this type of electronic tag are all The identification codes are completely stored in the RFID electronic tags. During the process of tires being sent for maintenance or running, important inform...
