Radio frequency identification label manufacturing equipment
Technical Field
The present invention relates to a printing apparatus, and more particularly, to a printing apparatus for printing a Radio Frequency Identification (RFID) tag.
Background
Radio Frequency Identification (RFID) technology is an important automatic Identification technology, and is one of the key technologies of the internet of things. Compared with the traditional identification mode, the RFID radio frequency identification automatically identifies the target object and obtains related data through radio frequency signals, manual intervention is not needed in identification work, and the RFID radio frequency identification can work in various severe environments.
The RFI D technology can identify high-speed moving objects and can simultaneously identify a plurality of labels, the operation is quick and convenient, and by means of the accurate, efficient and safe mode, the high anti-counterfeiting function and the characteristics of real-time monitoring of products, the application fields are more and more, and the RFI D technology is successfully applied to various fields of production and manufacturing, logistics management, commodity retail, medical health, public safety, animal breeding and the like.
The RFID tag is a tag manufactured by using a radio frequency identification technology, and generally comprises a tag antenna and a special radio frequency chip, wherein each tag has a unique identification code and can also be written with an information code of an identified article. When the RFID tag is used, the RFID reader-writer sends a radio frequency signal through the antenna to form an effective reading-writing area in a certain range, the tag is activated and feeds carried information back to the reader-writer after entering the effective reading-writing area, and the reader-writer receives the feedback signal and then analyzes and processes the feedback signal, so that the information of the tag chip is determined.
When the RFID tag is manufactured, a barcode or other data needs to be printed on the RFID tag paper to form the RFID tag for final use. When the RFID label is printed, the gap between the printing head and the paper pressing roller of the printer is small, so that the RFID label chip can be damaged by pressure. In the prior art, as shown in the invention patents of CN200910173784.7, CN201310078671.5, and CN201410198658.8, an RFID reader is usually installed on an RFID printer to identify a printed RFID chip, so as to determine whether the printed RFID chip can be used. However, this method can only identify the damaged RFID chip, and cannot reduce the damage of the RFID chip during printing.
In order to solve the above problems, the prior application proposes a RFID tag manufacturing apparatus in which an adhesive tape is provided on a printing medium, thereby reducing the force applied by a printing head to an RFID chip, and thus reducing damage to the RFID chip. However, the sticking positions are arranged on the two sides of the printing medium and are far away from the RFID chip, so that the acting force borne by the sticking strip is small, and the RFID chip can also bear certain acting force; on the other hand, after the RFID tag is manufactured, the RFID antenna is used to identify whether the RFID chip is damaged, and then the RFID chip is marked by a marking machine, so that the RFID chip can be used for user identification.

The embodiments described below with reference to the accompanying drawings are illustrative only for the purpose of explaining the present invention, and are not to be construed as limiting the present invention. Moreover, it is to be understood that the features of the various embodiments described herein are not mutually exclusive and can exist in a wide variety of combinations and permutations.
An rfid tag producing apparatus according to an embodiment of the present invention, referring to fig. 1, includes a printing medium input section 10, a printing information input section 20, an rfid tag position determining section 30, a printing area position determining section 40, a blank area determining section 50, an attaching area determining section 60, an attaching section 70, a platen roller 80, a print head 90, an rfid antenna 100, and an adhesive tape removing section 110.
The printing medium input unit 10 is used to input a printing medium having a radio frequency identification tag having an RFID chip therein. The printing medium may be thermal printing paper for printing words, symbols, or images for identifying the RFID tag on the surface thereof. And a print information input unit 20 for inputting information to be printed on a print medium. The print information input part 20 may be a man-machine interaction device including a mouse, a keyboard, a handwriting screen, etc., and the print information input part 20 may also receive information to be printed on a print medium from a network or a storage medium.
An RFID tag position determining section 30 for determining a position area of an RFID tag in a printing medium. Specifically, referring to fig. 2, the rfid tag position determining section 30 determines the highest point Y1 and the lowest point Y2 of the rfid tag 1 along the printing medium traveling direction, the leftmost point X1 and the rightmost point X2 perpendicular to the printing medium traveling direction when determining the location area of the rfid tag 1; lines L1 and L2 passing through Y1 dots and Y2 dots in parallel with the direction of travel of the printing medium, lines L3 and L4 passing through X1 dots and X2 dots perpendicular to the direction of travel of the printing medium are determined, and a region surrounded by the lines L1, L2, L3, and L4 is determined to be the radio frequency identification tag position region 2.
A print area position determination portion 40 that determines a print area 3 of the print information based on information that needs to be printed on the print medium, specifically, the print target position determination portion 40 determines a total area 4 based on straight lines L3 and L4 and both sides of the print medium, and the intersection of the print information area and the total area 4 is taken as the print area 3.
A blank area determination section 60 that determines a blank area 5 in which the rfid tag and the print information are not present in the print medium, based on the results of the rfid tag position determination section 30 and the print target position determination section 40; the area of the total area 4 excluding the printing area 3 and the rfid tag position area 2 is determined as a blank area 5.
And a pasting region specifying unit 60 that specifies the position of the pasting region 6 in the blank region 5. The pasting region determination section 60 determines the pasting region 6 as follows: moving the left side of the printing area 3 from the leftmost side by taking 1/4 of the width of the adhesive tape as a step length to judge whether the predicted adhering area of the adhesive tape is completely positioned in the blank area 5, and if the predicted adhering area is completely positioned in the blank area 5, taking the predicted area as a first adhering area 61; moving rightwards from the rightmost side of the printing area 3 by taking 1/4 of the width of the pasting strip as a step length, judging whether the predicted pasting area of the pasting strip is completely positioned in the blank area 5, and if the predicted pasting area is completely positioned in the blank area 5, taking the predicted pasting area as a second pasting area 62; the first pasting area 61 and said second pasting area 62 are merged into the pasting area 6. The pasting part 70 pastes the pasting strip on the first pasting area 61 and the second pasting area 62 respectively, and the thickness of the pasting strip is set to be slightly higher than the thickness of the radio frequency identification label, for example, 32 μm, so that when the printing head is contacted with the printing medium, the main stress acts on the pasting strip, the effect on the radio frequency label is reduced, and the damage to the radio frequency label is reduced. The length of the pasting strip along the advancing direction of the printing medium is the length of the distance between the Y1 point and the Y2 point projected in the advancing direction of the printing medium.
By the arrangement of the pasting region determining part 60, the first pasting region 61 and the second pasting region 62 are located at positions close to the RFID tag, so that the acting force applied to the RFID tag is further reduced, and the damage of the RFID tag is reduced.
