Description

Technical Field

[0001] The utility model relates to the technical field of RFID tags, and particularly relates to a production system for RFID tag antennas. Background Art

[0002] RFID (Radio Frequency Identification) is also known as an electronic tag, which is a communication technology that identifies specific targets through radio signals and reads and writes relevant data. It has the advantages of high-speed identification, resistance to harsh environments, and strong confidentiality. Therefore, it has been widely used in many fields such as logistics, warehouse management, medical care and identity identification, food processing, and real-time monitoring of production data and quality tracking in the industrial manufacturing process.

[0003] In an RFID tag, as the main energy transmission functional layer, the antenna is an electronic circuit designed according to the functions required by radio frequency identification. The traditional processing methods of RFID tag antennas include etching, printing, and electroplating, but they all have deficiencies. Therefore, at present, there is a method of manufacturing RFID antennas by die-cutting, which has the advantages of no pollution, convenient operation, energy conservation and environmental protection, and the production effect and efficiency are far higher than those of the etching method and the printing method, and it has good application prospects.

[0004] However, at present, after the RFID tag antenna is produced by die-cutting, it still needs to be manually inspected one to two times. And because it is inspected by the naked eye and then manually marked, there are problems of missed marking and mis-marking, which reduces the production efficiency and product quality, and the labor cost is relatively high. In addition, since the ink after marking is not easy to dry quickly, it still needs to be manually wiped with a dust-free cloth, which further reduces the production efficiency and there is also a risk of transfer of marking points. Summary of the Utility Model

[0005] The purpose of the utility model is to provide a production system for RFID tag antennas, which solves the technical problems that after the RFID tag antenna in the prior art is produced by die-cutting, it still needs to be manually inspected one to two times, resulting in reduced production efficiency and product quality, relatively high labor cost, and there is also a risk of transfer of marking points.

[0006] The utility model discloses a production system for RFID tag antennas, including:

[0015] In this application, by setting up the visual inspection unit, the inkjet coding unit and the control unit, the defective products can be automatically detected online and marked with inkjet codes, avoiding misjudgment and missed judgment, improving the marking accuracy, enhancing the production efficiency and product quality. And according to the stability of the die-cut antenna, the finished products can be obtained as soon as they are wound, without the need for re-inspection, thus reducing the labor and equipment costs.

[0023] Preferably, the bottom surface of the separating roller is at the same horizontal level as the discharge port of the die-cutting unit; with this solution, the composite substrate passes through the die-cutting unit in a horizontal posture, thereby improving the die-cutting effect and ensuring the quality of the antenna.

[0024] Preferably, it includes:

[0025] A second guiding roller is arranged between the separating roller and the flattening roller, and its bottom surface is at the same horizontal level as the bottom surface of the separating roller; with this solution, the carrier layer in the composite substrate passes through the separating roller in a horizontal posture, thereby improving the stability of the peeling between the waste area and the carrier layer, avoiding interference with the antenna area, and thus improving the finished product quality.

[0040] In order to better understand the above technical solution, the above technical solution will be described in detail below with reference to the accompanying drawings of the specification and specific embodiments.

[0041] Embodiment:

[0042] As Figure 1 shown, an RFID tag antenna production system is disclosed in an embodiment of the present application, which is used to produce RFID tag antennas by die-cutting and to detect and mark defective products online. Its specific structure includes: a die-cutting unit 1, a separating roller 2, a waste discharging and winding roller 3, a vision inspection unit 4, an inkjet coding unit 5, a UV curing lamp 6, a finished product winding roller 7, and a control unit 8.

[0043] The die-cutting unit 1 is used to perform die-cutting on the composite substrate. It is preferably a rotary die-cutting machine, including a die-cutting roller and an impression roller that cooperate up and down, and has the advantages of high efficiency and stability, being suitable for mass production, but is not limited thereto. It can also be other die-cutting devices, without specific limitation.

[0044] It should be noted that the composite substrate is a three-layer composite structure, sequentially including a conductive layer, an adhesive layer, and a carrier layer. Among them, the conductive layer can be a metal foil film, such as: aluminum film, copper film, etc.; the adhesive layer can ensure that the conductive layer is firmly attached to the carrier layer and maintains its shape and position during the die-cutting process; the carrier layer has certain adhesiveness and peelability, can easily separate the waste material from the antenna after die-cutting, and maintain the integrity and cleanliness of the antenna. It can be a PET film, release paper, or other polymer materials.

[0045] It can be understood that the die-cutting process cuts the composite substrate according to the RFID antenna pattern, and specifically cuts through the conductive layer and the adhesive layer, but retains the carrier layer, thereby forming an antenna area and a waste area on the carrier layer.

[0046] The separating roller 2 is used to separate the die-cut composite substrate into finished products and defective products, specifically to peel the waste area from the carrier layer; among them, the finished product refers to the carrier layer and the antennas attached thereto in the form of islands, and the defective product refers to the peeled waste area.

[0047] The waste discharging and winding roller 3 is used to wind the defective products, specifically to wind the peeled waste area.

[0048] The vision inspection unit 4 is used to collect images of the finished products, specifically to collect images of the antennas attached to the carrier layer in the form of islands; it is preferably composed of two 8K high-speed cameras, the length and width of its shooting range are 250mm×400mm, and the conventional recognition speed is 30m / min, thus fully meeting the production speed, but is not limited thereto, and can be adjusted accordingly according to the actual working conditions.

[0049] The inkjet coding unit 5 is used to spray marks on the defective products on the finished products, specifically to spray marks on the defective products among the antennas; it is preferably composed of a plurality of individual nozzles spliced side by side, so that the width of the inkjet coding range reaches 350mm, meeting the actual production requirements.

[0050] The UV curing lamp 6 is used to irradiate the ultraviolet rays on the sprayed finished product, so that the logo is quickly cured, thus avoiding the situation that the surface of the material is contaminated due to the uncured logo ink when the finished product is wound up.

[0051] The finished product winding roller 7 is used to wind up the cured finished product.

[0052] The input end of the control unit 8 is electrically connected to the vision detection unit 4, and the output end is electrically connected to the inkjet coding unit 5.

[0053] During on-line identification, the finished product passes through the vision detection unit 4, the inkjet coding unit 5 and the UV curing lamp 6 in sequence, and finally is wound up by the finished product winding roller 7, as Figure 1 and Figure 2 shown, and the specific control steps of the control unit 8 are as follows:

[0054] Step A: Obtain the image of the finished product collected by the vision detection unit 4;

[0055] Step B: Compare the image of the finished product with the template image to obtain a matching score;

[0056] Step C: Judge whether the matching score is less than the specified score. If so, proceed to the next step; if not, end;

[0057] Step D: Save the image of the finished product, and calculate the triggering time and position of the inkjet coding logo according to the relative distance between the vision detection unit 4 and the inkjet coding unit 5 and the production speed of the production line;

[0058] Step E: Control the air path and ink path of the inkjet coding unit 5 according to the triggering time and position of the inkjet coding logo, so as to perform inkjet coding.

[0059] It should be noted that during the production line adjustment stage, the inkjet coding position of the logo can be finely adjusted by changing the inkjet coding delay of the inkjet coding unit 5, so as to accurately adapt to the production speed of the production line and improve the inkjet coding accuracy.

[0060] Preferably, the control unit 8 can also store and record the number of defective products of the whole roll of antenna, which can be accurate to the number of defective products of each row of antennas and is also applicable to single-row finished products.

[0061] By setting the vision detection unit 4, the inkjet coding unit 5 and the control unit 8, the defective products can be automatically detected and inkjet coded on-line, thus avoiding misjudgment and missed judgment, improving the logo accuracy, production efficiency and product quality. According to the stability of the die-cut antenna, the finished product can be obtained as soon as the roll is out, without re-inspection, thus greatly reducing the labor and equipment costs. Then, the UV curing lamp 6 is used to quickly cure the logo, without manual wiping, further improving the production efficiency and avoiding the risk of logo point transfer.

[0062] In some embodiments, as Figure 1 shown, it further includes:

[0063] Two flattening rollers 9, arranged horizontally, above the separating roller 2, and between the separating roller 2 and the finished product winding roller 7, for enabling the finished product to pass horizontally under the visual inspection unit 4, the inkjet coding unit 5 and the UV curing lamp 6.

[0064] Through the above settings, the antenna on the finished product can pass under the visual inspection unit 4, the inkjet coding unit 5 and the UV curing lamp 6 in a facing state, thereby improving the clarity of the finished product image, the accuracy of the inkjet coding mark and the irradiation area of the light curing, and further improving the detection, inkjet coding and curing effects.

[0065] Based on the above embodiments, as Figure 1 shown, it further includes:

[0066] The first guiding roller 10, arranged between the flattening roller 9 and the finished product winding roller 7, and below the flattening roller 9; for enabling the finished product to move in a V-shaped path to be wound by the finished product winding roller 7 through the guiding of the first guiding roller 10 after passing through the flattening roller 9.

[0067] Through the above settings, it is avoided that the finished product is offset or disordered during the winding process, thereby ensuring the winding quality, and the tension of the finished product during the winding process can be adjusted and controlled, avoiding problems such as wrinkles, slack or breakage caused by uneven tension.

[0068] In this embodiment, as Figure 1 shown, the waste winding roller 3 is arranged above the separating roller 2 and on the side of the separating roller 2 away from the die-cutting unit 1.

[0069] It can be understood that since the conductive layer in the composite substrate is on the top surface during the production process, through the above settings, the waste can be guided to move upward and gradually away from the finished product.

[0070] Through the above settings, the stability of the waste area peeled off on the bearing layer is improved, thereby ensuring the production smoothness, reducing the failure rate and improving the product quality.

[0071] In this embodiment, as Figure 1 shown, the bottom surface of the separating roller 2 is at the same horizontal plane as the discharge port of the die-cutting unit 1, and it is used for enabling the composite substrate to pass through the die-cutting unit 1 in a horizontal posture, thereby improving the die-cutting effect and ensuring the antenna quality.

[0072] In this embodiment, as Figure 1 shown, it further includes:

[0073] The second guiding roller 11 is arranged between the separating roller 2 and the laying roller 9, and its bottom surface is on the same horizontal plane as the bottom surface of the separating roller 2; it is used to make the bearing layer in the composite substrate pass through the separating roller 2 in a horizontal posture, thereby improving the stability of the peeling between the waste area and the bearing layer, avoiding interference with the antenna area, and thus improving the finished product quality.

[0074] In this embodiment, as Figure 1 shown, it further includes:

[0075] The third guiding roller 12 is arranged above the separating roller 2 and is located on the side of the separating roller 2 close to the die-cutting unit 1; it is used to make the waste move along a V-shaped path to be wound up by the waste discharging and winding roller 3 after being separated by the separating roller 2 through the guiding of the third guiding roller 12.

[0076] Through the above settings, it is avoided that the waste is offset or disordered during the winding process, thereby ensuring the winding quality, and the tension of the waste during the winding process can be adjusted and controlled, avoiding problems such as wrinkles, slack or breakage caused by uneven tension.

[0077] In the description of the present utility model, a large number of specific details are described. However, it can be understood that the embodiments of the present utility model can be practiced without these specific details. In some instances, well-known methods, structures, and technologies are not shown in detail so as not to obscure the understanding of this specification.
