Description

Technical Field

[0001] The invention relates to the technical field of RFID label paper printing, and in particular to an RFID label printing method based on a thermal transfer printer. Background Art

[0002] A label printer is a printer that can be connected to a computer or not, has a built-in input keyboard or intelligent touch screen operation, has certain fonts, character libraries and a considerable number of label template formats built in, and users can directly input, edit and layout the label content according to their needs through the LCD screen of the machine body, APP software or computer connection, and then directly print out the label. The current printing methods of label printers include visible data printing and invisible data printing (such as RFID label printing). The visible data printing refers to the reflection of text and / or graphics on the label paper, and the invisible data printing refers to the setting of RFID antenna on each label paper, and the setting of RFID reader-writer on the label paper output path of the printer to read and write invisible data one by one to each label paper.

[0003] In the prior art, after the blank RFID label is printed by a printer, the RFID label information is written by a dedicated RFID reader / writer. The printing action and the RFID label writing action cannot be completed at one time, which is inefficient.

[0004] Placing an RFID reader inside the printer to read and write RFID tag information while printing the label has high printing efficiency, but low accuracy and poor print quality, which leads to slow and inaccurate reading during the reading process. Summary of the invention

[0005] The object of the present invention is to provide an RFID label printing method based on a thermal transfer printer to solve the above-mentioned background problems.

At the same time, the printing power value is calculated based on the printing distance value, and the printing speed value is further calculated to print the RFID label paper, and the printed RFID label paper is read and tested to avoid unqualified RFID label paper. At the same time, after unqualified RFID label paper appears, the printing data during the printing process of the RFID label paper can be adjusted to update the printing quality performance model, so as to ensure that qualified RFID label paper can be stably obtained in the subsequent printing process, improve the printing efficiency of RFID label paper, and ensure the printing quality of RFID label paper;

[0008] At the same time, by monitoring and adjusting the printer's printing power and printing speed, when the printing quality is poor, the printing power and printing speed can be adjusted in time to quickly adjust the printing of the RFID label paper to ensure that RFID label paper with qualified printing quality can be obtained in the subsequent printing process.

[0065] Step 2: Design and add a control interface on the printer's control mainboard, and connect it to the RFID tag reader. During the design process, the control interface should support the communication protocol and data format of the RFID tag reader to ensure accurate data transmission and processing.

[0066] Step 3: The printer locates the RFID label paper based on the paper data; the printer receives the RFID label printing instruction, the printer motor controls the RFID label to eject the paper forward, and prints the RFID label paper based on the travel data. After the operation is completed, the printing motor returns the paper to the initial position;

[0067] Specific:

[0068] S1: Acquire paper data, including a paper long side deviation value PC and a paper short side deviation value PD; wherein the paper long side deviation value PC refers to the distance difference between the center point of the long side of the paper and the center point of the initial target position of the paper along the long side direction, and the paper short side deviation value PD refers to the distance difference between the center point of the short side of the paper and the center point of the initial target position of the paper along the short side direction;

[0069] Determine whether the paper long side deviation value PC and the paper short side deviation value PD are zero respectively;

[0070] If the paper long side distance value PC is equal to zero and the paper short side deviation value PD is equal to zero, a positioning accuracy signal is generated;

[0071] If the paper long side distance value PC and / or the paper short side deviation value PD are not equal to zero, a positioning adjustment signal is generated; at this time, the RFID tag value is positioned based on the positioning adjustment signal;

[0072] If the paper long side deviation value PC is less than zero, the RFID label paper is moved forward;

[0073] If the paper long side distance value PC is greater than zero, the RFID label paper is moved backward;

[0074] If the paper short edge deviation value PD is less than zero, the RFID label paper is moved rightward;

[0075] If the paper short edge deviation value PD is greater than zero, the RFID label paper is moved to the left;

[0076] It should be noted that in the direction of movement of the RFID tag paper, the front, back, left, and right directions are based on the direction in which the staff faces the RFID tag paper for insertion as the front direction;

[0077] S2: Based on the accurate positioning signal, obtain the printing distance value LD of the RFID label paper, and based on the printing distance value LD, The printing power value WP is obtained by calculation; wherein a is the printing distance coefficient value, and b is the power correction coefficient;

[0078] The printing power value required by the RFID label paper during the printing process is calculated based on the printing distance value, and then subsequent printing calculations are performed based on the printing power value, thereby ensuring the quality of the RFID label paper during the printing process and the accuracy of information transmission;

[0079] S3: Based on the print power value WP, based on the print quality performance qualified value BXhg, through the print quality performance model The print speed value WV is calculated and obtained; wherein c is the print speed performance coefficient, d is the print power performance coefficient, and e is the performance correction coefficient;

[0086] If the print completion quality performance value ZLbx is less than the print quality performance qualified value BXhg, a poor print performance signal is generated; at this time, it means that the RFID label paper is not printed properly and needs to be reprinted to ensure the stability of the RFID label paper in subsequent use and the accuracy of information reading;

[0087] If the print completion quality performance value ZLbx is greater than or equal to the print quality performance qualified value BXhg, a print performance qualified signal is generated; at this time, it means that the RFID label paper can meet the requirements of reading distance and reading time during the information reading process, that is, the printing is qualified;

[0088] S5: Based on the poor printing performance signal, the printing power value WP is adjusted, and then the printing speed value MV is adjusted, and the RFID label paper is reprinted, and then S4 is executed;

[0089] At this time, the RFID label paper may fail to meet the requirements during the printing process due to the printing speed being too fast or the printing power being too low, resulting in the problem of low accuracy or slow reading speed of the information on the RFID label paper during the reading process;

[0090] This solution adjusts the position state of the RFID label paper during the printing process to avoid the problem of RFID label paper offset during the printing process. At the same time, the printing power value is calculated based on the printing distance value, and the printing speed value is further calculated to print the RFID label paper and perform a reading test on the printed RFID label paper to avoid the occurrence of unqualified RFID label paper. At the same time, after unqualified RFID label paper appears, the printing data during the printing process of the RFID label paper can be adjusted to update the printing quality performance model to ensure that qualified RFID label paper can be stably obtained in the subsequent printing process, thereby improving the printing efficiency of the RFID label paper and ensuring the printing quality of the RFID label paper.
