Description

Technical Field

[0001] The utility model belongs to the technical field of rubber products, and in particular relates to a device capable of batch-producing RFID electronic tags for tires. Background Art

[0002] The statements in this section merely provide background technical information related to the present invention and do not necessarily constitute prior art.

[0003] RFID electronic tags are widely used in the tire industrialization. RFID electronic tags can be written with tire production data, sales data, usage data, retreading data, etc., and implanted inside the tire. The corresponding data can be collected and read through the terminal at any time. Combined with the corresponding management software, the data of the entire life cycle of the tire can be recorded and traced.

[0004] RFID tags implanted in tires require adhesive bonding to protect the tags and prevent them from affecting tire performance. Currently, most tire-implanted tags are square or nearly square after packaging, which doesn't match the tire's shape and affects tire uniformity. RFID tags are currently produced using manual single-strip sealing, which is cumbersome and inefficient. The low degree of standardized labeling can easily damage the tags, and a small number of RFID tags need to be implanted in tires during tire testing. Existing RFID tag packaging equipment, such as patent 201420547768.6, doesn't require manual single-strip sealing, but it's all mass-produced on assembly lines. The specifications and types of RFID tags produced are limited, making them less suitable for large-scale tire implantation. Furthermore, the encapsulated RFID tags are all rectangular, which can affect tire uniformity after implantation. Utility Model Content

[0037] It should be noted that the following detailed descriptions are exemplary and are intended to provide further explanation of the present invention. Unless otherwise specified, all technical and scientific terms used herein have the same meanings as those commonly understood by those skilled in the art to which the present invention belongs.

[0038] It should be noted that the terms used herein are only for describing specific embodiments and are not intended to limit the exemplary embodiments according to the present invention.

[0039] In the absence of conflict, the embodiments of the present invention and the features in the embodiments can be combined with each other.

[0040] RFID, short for Radio Frequency Identification (RFID), is a type of automatic identification technology that uses radio frequency (RF) for contactless, two-way data communication. RFID tags are read and written using RF, enabling identification and data exchange. RFID tags offer broad application prospects, boasting advantages such as fast scanning speed, compact size, high capacity, long lifespan, and data read / write capabilities. As a rising technology in the Internet of Things (IoT) industry, they are widely used in tire logistics and warehousing management, information and identity traceability, and full lifecycle management.

[0041] On July 1, 2016, four industry standards, including those for radio frequency identification (RFID) tags for tires, officially came into effect, approved by the Ministry of Industry and Information Technology. These standards specify the functional performance, implantation methods, and encoding methods of RFID tags to ensure tire safety. The implementation of these standards will accelerate the adoption of this technology within the industry and promote the rapid development of the smart tire industry.

[0042] The utility model discloses a device for batch production of RFID electronic tags for tires. Through the device, RFID electronic tags can be wrapped with rubber materials in batches to meet the needs of tire implantation. Figure 1 and Figure 2 As shown, it includes: a lower base plate 1 and an upper cover plate 2;

[0043] At least two RFID electronic tag placement holes 4 are provided on the bottom plate 1; the RFID electronic tag placement holes 4 are evenly arrayed on the bottom plate 1;

[0044] At least two cutting knives 3 are provided on the upper cover 2. The cutting knives 3 are evenly arranged in an array on the upper cover 2. The cutting knives can be accommodated in the RFID electronic tag positioning hole 4.

[0045] The upper cover plate 2 is further provided with a plurality of exhaust needles 5 .

[0046] The lower plate 1 and the upper cover plate 2 are both rectangular in shape, and the lower plate 1 is larger than the upper cover plate 2. In some embodiments, the lower plate 1 is 200 mm wide, 300 mm long, and 50 mm high, while the upper cover plate 2 is 190 mm wide, 290 mm long, and 50 mm high.

[0047] In some embodiments, the lower pad 1 and the upper cover plate 2 are both made of steel. Positioning columns 6 are provided on the four corners of the lower pad 1, and positioning holes 7 are provided on the four corners of the upper cover plate 2. The positioning columns 6 can be inserted into the positioning holes 7 to play a positioning role. In some embodiments, the diameter of the positioning columns 6 can be 4 mm and the height can be 50 mm; the diameter of the positioning holes 7 can be 5 mm and the depth can be 50 mm.

[0048] When the utility model is in use, the cutting blade 3 of the upper cover plate 2 is accommodated in the RFID electronic tag positioning hole 4 of the lower pad 1, thereby achieving accurate and efficient cutting work.

[0049] like Figure 3 As shown, the cutting blade 3 includes a first side cutting blade 31, a first curved cutting blade 33, a second side cutting blade 32, and a second curved cutting blade 34, all connected in sequence. These four cutting blades are integrated into a fan-shaped ring and have a diameter of 1 mm. The cutting blades 3 are perpendicular to the upper cover 2 and can be integrated with the upper cover 2 or designed separately. They are all made of steel and extend 5 mm beyond the upper cover 2.

[0050] The RFID tag placement hole 4 is in the form of a fan-shaped ring, and the arc curve of the fan-shaped ring is adapted to the arc of the tire. This is done to evenly distribute the attached RFID on the tire, achieve a close fit between the RFID and the tire, and improve the tire's dynamic performance. In some embodiments, the RFID tag placement hole 4 can be set to a height of 50mm (the same height as the bottom plate), a length of 80mm, and a width (the line connecting the midpoints of the two arc-shaped edges) of 20mm. In another embodiment, the RFID tag placement hole 4 is set to a length greater than the length of the RFID tag by 10mm, and a width (the line connecting the midpoints of the two arc-shaped edges) greater than the tag width by 15mm.

[0051] The exhaust needle 5 is positioned within the fan ring area of ​​the cutting blade 3, parallel to the cutting blade 3. The exhaust needle and the upper cover 2 are integrally designed and made of steel. The length of the cutting blade 3 and the exhaust needle 5 are equal, allowing for simultaneous exhaust during cutting. In some embodiments, the exhaust needle 5 is 5 mm long and 0.5 mm in diameter.

[0052] In some embodiments, as Figure 4As shown, the number of exhaust needles 3 in the fan ring area of ​​each cutting knife 3 can be 14, and the arrangement of the exhaust needles 3 leaves an area for accommodating the placement of the RFID electronic tag 8, wherein the exhaust holes generated by the two exhaust needles set at points A and B are respectively located at the two ends of the RFID electronic tag 8, and are on the same straight line as the radio frequency antenna 82 of the RFID electronic tag. Among them, the exhaust needle at point A is set at a position that is a certain distance away from the first side cutter 31 and biased towards the first arc cutter 33, and the exhaust needle at point B is set at a certain distance away from the second side cutter 32 and biased towards the first arc cutter 33. Eight exhaust needles are evenly arranged between points A and B, and the line connecting the eight exhaust needles and the exhaust needles at points A and B is an arc, which is opposite to the arc opening of the first arc cutter 33; the remaining four exhaust needles are divided into two groups, such as Figure 6 As shown, the line connecting the four exhaust needles is also arc-shaped, the spacing within the two groups is smaller than the spacing between the two groups, and the spacing between the two groups is larger than the size of the side of the substrate 81 of the RFID electronic tag without the radio frequency antenna 82. The radio frequency antenna 82 of the RFID electronic tag and the exhaust holes generated by points A and B should be on a straight line; it should be noted that the position of any exhaust hole does not coincide with the RFID electronic tag. The arrangement of the exhaust needles 5 in the above manner can ensure that the puncture position is the gas storage position to evenly remove the sealed gas and avoid the generation of bubbles. The two arc-shaped openings formed by the above arrangement of the exhaust needles are opposite to each other, and an area that can accommodate an RFID electronic tag is left in the middle of the two arcs.

[0053] It should be noted that the cutting blade 3, the RFID tag placement hole 4 and the two arc-shaped connecting lines of the exhaust needle 3 in this embodiment are all symmetrical structures, and the four symmetry axes can coincide.

[0054] When using the present invention: first, lay the lower film flat on the upper surface of the lower pad 1. The film can protrude into a fan-shaped shape through the RFID electronic tag placement hole 4 below. According to the cross mark on the bottom surface of the RFID electronic tag placement hole (the cross mark is located at the midpoint of the line connecting the two arc midlines of the RFID electronic tag placement hole, the first line of the cross mark coincides with the midline, the second line is perpendicular to the midline, and the exhaust holes formed by the exhaust needles at points A and B are on the same line as the second straight line), place the RFID electronic tag 8 in the fan-shaped area, as shown in FIG. Figure 5As shown. It should be noted that the specifications and functions of the RFID electronic tags here can be different, so that multiple types of RFID electronic tags can be produced at one time. Then, lay the upper film flat on the RFID electronic tag 8 and keep it flat; align the lower plate 1 with the upper cover plate 2 through the fixing columns 6 on the lower plate 1 and the fixing holes 7 on the upper cover plate 2, and press the upper cover plate 2 vertically into the lower plate 1. Use the exhaust needle 5 and the cutting knife 3 to complete the cutting and exhaust of the RFID electronic tags 8, and realize the mass production of RFID electronic tags for tires, as shown. Figure 6 As shown, the device in this embodiment can produce 18 independent RFID electronic tags at a time.

[0055] This example uses the implantation of RFID tags in an all-steel radial tire as an example to verify RFID tag implantation. The optimal implantation location for an all-steel radial tire is at the end of the tire carcass turnup. This location minimizes tire deformation and lacks tire cord wire, minimizing signal shielding and tearing and distortion of the RFID tag. Furthermore, this location should be at least 20 mm away from the rim edge, which can prevent signal interference to a certain extent.

[0056] The RFID tag is identified based on the tire material distribution map and implanted at the outer endpoint of the apex film. Tracking of the RFID tag ensures that after lamination and reverse wrapping, the tag remains intact, ensuring scanning failure and unaffected by the molding cycle. Furthermore, the RFID tag remains positioned at the reverse wrapping endpoint after lamination. Furthermore, verification using X-ray machines, cat's eye bubble machines, uniformity dynamic balancing equipment, and durable machine tools confirms that the tire RFID tags produced by this device do not affect tire performance.

[0057] Although the above description of the specific implementation methods of the present invention is combined with the accompanying drawings, it does not limit the scope of protection of the present invention. Technical personnel in the relevant field should understand that on the basis of the technical solution of the present invention, various modifications or deformations that can be made by technical personnel in this field without creative work are still within the scope of protection of the present invention.
