Description

Technical Field

[0001] The present invention relates to the field of label printing, and in particular to an RFID label printing management method and system. Background Art

[0002] The widespread use of labels and the continuous development of label varieties have naturally driven the development of label printing technology. Label printing covers all printing methods, including flat, convex, concave, and mesh. However, label printing still has problems. The printing process may cause ink layers to stick together or bubbles to form, affecting the appearance of the finished product. This usually requires checking the cleaning of the printing equipment and the proper operating parameters, and taking appropriate measures to avoid it. Improper color management can cause the finished product color to not match the original design. Strengthening color calibration and using a professional color management system can help reduce the occurrence of such problems. This is especially important for RFID tags.

[0003] In summary, a RFID label printing management method and system are needed to address the deficiencies in the existing technology. Summary of the Invention

[0004] In view of the shortcomings of the existing technology, the present invention provides an RFID label printing management method and system, aiming to solve the above problems.

[0005] To achieve the above object, the present invention provides the following technical solution: a RFID label printing management method, comprising the following steps:

[0006] Step S1: Input the RFID label design draft into the control unit, and the control unit controls the feeding unit to feed the printing substrate into the first printing unit to perform the initial printing of the RFID label;

[0007] Step S2: Record the RFID printing area with the first camera unit, compare the color with the RFID label design draft, and determine whether it meets the design color requirements. After verification, perform initial curing through infrared drying;

[0008] Step S3: The control unit sends the printed substrate to the second printing unit again to print the RFID label for the second time, so that the printed line width of the RFID label is larger than the designed line width;

[0009] Step S4: Record the RFID printing area through the second camera unit, compare the color with the RFID label design draft, and determine whether it meets the design color requirements. After verification, perform secondary curing;

[0010] Step S5: etching the RFID tag printed circuit using a laser emission unit so that the RFID tag circuit width meets the design requirements;

[0020] Step A5: Verify again and repeat steps A3-A4 until the verification is passed;

[0021] Step A6: Record the adjusted parameters and results, and save the ICC profile generated after each adjustment.

[0024] Step B2: Selecting a suitable ink for widening the substrate and determining the printing starting point based on the first printing parameters. The control unit sends the substrate after the first printing to the second printing unit for secondary widening printing.

[0025] Optionally, in step S5, etching the RFID tag printed circuit by the laser emitting unit is performed in the following manner:

[0026] Step C1: a laser beam is emitted by a laser generator, and the laser beam is expanded and collimated by a laser beam expander;

[0027] Step C2: Using a laser diffraction lens, the laser beam is diffracted and homogenized to ensure that the laser beam meets the RFID tag etching requirements;

[0028] Step C3: Etch the second widened printed part according to the RFID tag design draft to make the RFID tag route meet the design width requirements.

[0035] Step E2: Select a suitable breakdown tool to prepare for breakdown at the location of the insulation layer to be broken through;

[0061] In order to more clearly illustrate the embodiments of the invention or the technical solutions in the prior art, the following briefly introduces the drawings required for use in the embodiments or the description of the prior art. Obviously, the drawings described below are only some embodiments of the invention. For ordinary technicians in this field, other drawings can be obtained based on these drawings without paying any creative work.

[0062] like Figure 1 As shown, a RFID label printing management method includes the following steps:

[0063] Step S1: Input the RFID label design draft into the control unit, and the control unit feeds the printing substrate into the first printing unit to perform the initial printing of the RFID label;

[0064] After the RFID tag design draft is input into the control unit, the control unit will generate a configuration file based on the RFID tag design draft and identify the frequency, size, pattern, text and color of the RFID tag. At the same time, it will also consider the position of the RFID chip and define the data format stored on the RFID chip, including the encoding method and data structure.

[0065] Step S2: Record the RFID printing area with the first camera unit, compare the color with the RFID label design draft, and determine whether it meets the design color requirements. After verification, perform initial curing through infrared drying;

[0066] like Figure 2 As shown, color contrast is performed in the following ways:

[0067] Step A1: Using the standard color side view, a standard color card is produced and calibrated to generate a printing standard color card;

[0068] Step A2: Scanning the printed standard color card through the scanning unit and generating an ICC profile;

[0069] Step A3: Use a camera to take a photo or video of the printed label area and generate a color comparison file. Compare the color comparison file with the ICC profile to determine whether the color meets the design requirements.

[0070] Step A4: If the color meets the requirements, the process proceeds to the next step. Otherwise, the calibration unit records the color deviation based on the selected ICC profile and generates a new ICC profile by adjusting the color parameters.

[0071] Step A5: Verify again and repeat steps A3-A4 until the verification is passed;

[0072] Step A6: Record the adjusted parameters and results, and save the ICC profile generated after each adjustment.

[0073] Step S3: The control unit sends the printed substrate to the second printing unit again to print the RFID label for the second time, so that the printed line width of the RFID label is larger than the designed line width;

[0074] like Figure 3 As shown, specifically:

[0075] The first printing of RFID tags is completed using conventional processes. The main goal of this stage is to form the basic circuit pattern.

[0076] Drying or curing: After the first printing is completed, the printed product needs to be properly dried or cured to ensure that the ink of the first printing is completely fixed and ready for the second printing.

[0077] Adjust printing parameters: In order to increase the line width, before the second printing, it is necessary to adjust the relevant parameters of the printing equipment, including but not limited to printing pressure, printing speed and ink selection. It is very important to choose the right ink because it needs to be compatible with the ink used for the first time and be able to provide good adhesion and conductivity.

[0078] Second printing: When all preparations are ready, the control unit will send the substrate that has completed the first printing back into the printing unit for a second printing. The goal of this printing is to add additional material to the original line, thereby achieving the purpose of widening the line. It should be noted that the printing position must be precisely controlled to avoid affecting other non-printing areas.

[0079] Inspection and Testing: After the second printing is complete, the finished product needs to be carefully inspected to ensure that the line width meets the design requirements and there are no short circuits or other quality issues. In addition, the RFID tag's functionality should be fully tested, including read and write distance, data integrity, and other aspects, to ensure that the product's performance meets the expected standards.

[0080] Optimization and adjustment: If problems are found during the inspection or testing process, it may be necessary to return to the design preparation or printing parameter adjustment stage and fine-tune the relevant parameters until the best effect is achieved.

[0081] Step S4: Record the RFID printing area through the second camera unit, compare the color with the RFID label design draft, and determine whether it meets the design color requirements. After verification, perform secondary curing;

[0082] like Figure 2 As shown, color contrast is performed in the following ways:

[0083] Step A1: Using the standard color side view, a standard color card is produced and calibrated to generate a printing standard color card;

[0084] Step A2: Scanning the printed standard color card through the scanning unit and generating an ICC profile;

[0085] Step A3: Use a camera to take a photo or video of the printed label area and generate a color comparison file. Compare the color comparison file with the ICC profile to determine whether the color meets the design requirements.

[0086] Step A4: If the color meets the requirements, the process proceeds to the next step. Otherwise, the calibration unit records the color deviation based on the selected ICC profile and generates a new ICC profile by adjusting the color parameters.

[0087] Step A5: Verify again and repeat steps A3-A4 until the verification is passed;

[0088] Step A6: Record the adjusted parameters and results, and save the ICC profile generated after each adjustment.

[0089] Step S5: etching the RFID tag printed circuit using a laser emission unit so that the RFID tag circuit width meets the design requirements;

[0090] like Figure 4 As shown, specifically:

[0091] Step C1: a laser beam is emitted by a laser generator, and the laser beam is expanded and collimated by a laser beam expander;

[0092] Step C2: Using a laser diffraction lens, the laser beam is diffracted and homogenized to ensure that the laser beam meets the RFID tag etching requirements;

[0093] Step C3: Etch the second widened printed part according to the RFID tag design draft to make the RFID tag route meet the design width requirements.

[0094] Step S6: sending the etched label to the third printing unit for printing the insulating protective layer, and then UV curing it through the UV light emitting unit;

[0095] like Figure 5 As shown, specifically:

[0096] Before printing the insulating protective layer, the etched label must first be checked for quality standards, including parameters such as line clarity, depth, and width. This ensures that the etched label surface is clean and dust-free, as any impurities may affect the adhesion quality of the insulating layer and the performance of the final product.

[0097] Select suitable insulating ink according to the working environment (such as temperature, humidity, etc.) and physical properties of the label. The ink should have good adhesion, chemical resistance and weather resistance.

[0098] Adjust the printing equipment parameters, including printing speed, printing pressure, and ink flow, based on the characteristics of the insulating ink and the desired coating thickness. The etched label is then fed into the third printing unit, where the insulating protective layer is printed. Ensure uniform printing to avoid air bubbles or uncovered areas.

[0099] After printing is completed, check the uniformity and integrity of the insulation layer and perform local repairs if necessary.

[0100] Step S7: locally breaking down and connecting the insulating protective layer through the breaking down connection unit, so that the printed conductive layer forms different logic circuits;

[0101] like Figure 6 As shown, first, based on the required logic circuit design, determine where insulation-piercing connections are required. This step requires a detailed circuit diagram and precise coordinate information.

[0102] Choose the right penetration tool: Common penetration tools include laser penetration, needle penetration, etc. Laser penetration is widely used due to its high precision and non-contact operation.

[0103] Prepare the sample and ensure that the label to be processed has completed the printing and UV curing of the insulating protective layer and the surface is clean and dust-free.

[0104] Local breakdown connection:

[0105] The laser breakdown steps are as follows:

[0106] Calibrate the laser equipment: According to the circuit diagram and coordinate information, calibrate the position and focal length of the laser equipment, set the appropriate laser power and pulse frequency to ensure that the breakdown depth only penetrates the insulating layer without damaging the underlying conductive layer.

[0107] Programming control: Import the circuit diagram into the laser control system, set the coordinates and order of the breakdown points, and write the control program to ensure that the laser head moves along the predetermined path and accurately breaks through each designated position.

[0108] Perform the laser puncture: Place the label on the laser machine's workbench, ensuring it is fixed and flat. Start the laser machine and perform local puncture according to the preset program. Pay attention to the puncture process to ensure the accuracy and consistency of each puncture point.

[0109] Check the breakdown effect: Use a microscope or high-resolution camera to check the breakdown point to ensure that the breakdown depth and diameter meet the requirements. If necessary, local repair or re-breakdown can be performed.

[0110] The steps for acupuncture breakdown are as follows:

[0111] Prepare the needle: Select a needle of appropriate diameter and hardness to ensure that it can penetrate the insulating layer without damaging the conductive layer.

[0112] Calibrate the needle position: Fix the needle at the precise position according to the circuit diagram and coordinate information.

[0113] Perform puncture: Place the label on the workbench, ensure that the position is fixed and flat, and perform local puncture with the needle manually or automatically controlled according to the predetermined path and sequence.

[0114] Check the breakdown effect: Use a microscope or high-resolution camera to check the breakdown point to ensure that the breakdown depth and diameter meet the requirements. If necessary, local repair or re-breakdown can be performed.

[0115] Post-processing cleaning: Use appropriate solvents or detergents to clean the punctured labels to remove residues and impurities generated during the puncture process.

[0116] Check the continuity: Use a multimeter or special test instrument to check the continuity between the breakdown points to ensure that the connection between the conductive layers is reliable.

[0117] Insulation repair: If there is insulation damage around certain breakdown points, insulating ink can be used for local repair to ensure that the overall insulation performance is not affected.

[0118] Step S8: Recycling the printed RFID tags through a recycling unit;

[0119] Before recycling, testing and verification are also carried out to test the reading and writing distance and recognition rate of RFID tags.

[0120] An RFID label printing management system adopts an RFID label printing management method, comprising:

[0121] Control unit, used to control the entire RFID label printing process;

[0122] a feeding unit for conveying the printing substrate to the printing unit;

[0123] A camera unit is used to perform color comparison and judgment on RFID tags;

[0124] Laser unit, used to etch the printed circuit of RFID tags;

[0125] UV light emitting unit, used for UV curing the printed insulating protective layer;

[0126] A breakdown connection unit, used for breaking through the insulating protective layer to make a breakdown connection;

[0127] The ink unit is used to provide printing ink for printing RFID labels.

[0128] The control unit adjusts the parameters of the printing device, including but not limited to operating temperature, printing pressure, printing speed, ink type and ink flow.

[0129] The types of breakdown of connection units include laser breakdown and needle puncture breakdown;

[0130] Laser breakdown is to adjust the breakdown depth and plane size by adjusting the laser power and pulse frequency;

[0131] Needle puncture is a method of achieving penetration connection by selecting a needle with appropriate diameter and hardness and controlling the penetration depth.

[0132] The present invention uses standard color cards and ICC profiles to perform color comparison and correction, ensuring that the printed color is consistent with the design draft, thereby improving color accuracy. The control unit controls the entire printing process, from feeding, printing, color comparison, curing to breakdown connection, achieving a high degree of automation, reducing manual intervention, and improving production efficiency. The control unit can adjust the parameters of the printing equipment, including operating temperature, printing pressure, printing speed, ink type and ink flow, to ensure that each printing can achieve the best effect, reducing debugging time and scrap rate.

[0133] Through the initial printing and initial curing, as well as the secondary printing and secondary curing, the line width is precisely controlled by laser etching to ensure the stability and integrity of the ink layer, avoid the problem of ink layers sticking to each other or generating bubbles, ensure that the RFID tag line meets the design requirements, and improve printing accuracy.

[0134] By selecting appropriate insulating ink and adjusting printing parameters, we ensure the uniformity and integrity of the insulating protective layer, thereby improving the chemical resistance and weather resistance of the RFID tag. By using laser or needle penetration, we precisely control the penetration depth and plane size to ensure reliable connection between the conductive layers, thereby improving the electrical performance of the RFID tag. Through multiple inspections and tests, we ensure the quality of each step, reduce the production of unqualified products, and lower production costs.

Any modifications, equivalent substitutions or improvements made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
