Description

Technical Field

[0001] This invention relates to the field of RFID production technology, and in particular to an RFID tag composite equipment and composite process capable of online multi-color printing. Background Technology

[0002] The common lamination method for existing RFID tags involves pre-laminating the inlay between the label paper and the backing paper, and then using die-cutting equipment to cut it in half into independent tags with a uniform backing material. For example, the existing patent: CN202210968786.0, "A High-Speed ​​Lamination Die-Cutting Process and Equipment for RFID Tags," uses a complex reverse transfer process, requiring three types of material strips: label backing paper, inlay backing paper, and backing film. The corresponding equipment needs to be equipped with three independent unwinding and winding units, as well as a complex reverse transfer knife holder. This results in a complex overall structure and a large length of equipment. Moreover, the final product of this equipment is a semi-finished RFID tag roll that cannot be used directly. This equipment cannot achieve automated production from raw materials to finished RFID tags. It is still necessary to manually transfer the semi-finished RFID tag roll to other equipment and cooperate with 3-6 different other machines to perform unwinding, printing, information reading and writing, and winding of the semi-finished RFID tag roll to obtain a usable finished RFID tag roll, which reduces the production efficiency of RFID tags. Summary of the Invention

[0003] This invention proposes an RFID tag lamination device and process capable of online multi-color printing. After die-cutting the tags, they are then printed online. The printed tags are first peeled from the tag backing paper, and then the inlay layer is laminated onto the tag backing paper. Finally, the printed tags are laminated a second time. The entire process only requires one tag backing paper to complete the lamination of the entire RFID tag paper. Due to the greatly simplified lamination process, not only is the equipment integrated and simplified, but production efficiency and product qualification rate are also greatly improved.

Inlay peeling transition unit for peeling off the inlay layer and bonding it with the label backing paper; A lamination assembly for pressing together the laminated printed label, inlay layer, and original or new blank label backing paper; Reading and writing tagging unit for reading and marking RFID tag paper; A winding mechanism used to wind up continuous RFID tag paper.

[0005] As a preferred technical solution, the unwinding mechanism includes a sliding seat, which is slidably mounted on the frame along the Y-axis via a pair of first linear guides. An electric cylinder is installed between the sliding seat and the frame. An original label tape unwinding shaft is rotatably mounted on the sliding seat. A follower guide shaft is hinged to the sliding seat and is located downstream of the original label tape unwinding shaft. Two pressing and fixing guide devices are provided between the unwinding mechanism and the die-cutting knife holder. A receiving platform is fixedly installed on the frame between the two pressing and fixing guide devices. Each pressing and fixing guide device includes a pressing and fixing guide shaft. The pressing and fixing guide shaft includes a fixed shaft fixedly installed on the frame. A roller is rotatably installed on the fixed shaft. A pressing frame is fixedly installed on the fixed shaft. A pressing plate is slidably installed on the pressing frame. A manual clamp is provided between the pressing plate and the pressing frame to press the original label material against the roller.

[0006] As a preferred technical solution, the digital printer has a pre-press buffer mechanism upstream and a post-press buffer mechanism downstream. Both the pre-press buffer mechanism and the post-press buffer mechanism include a buffer guide shaft and a pair of fixed guide shafts. Each of the fixed guide shafts is rotatably mounted on the frame, and each of the buffer guide shafts is slidably mounted on the frame via a second linear guide rail. A compression spring is provided between the buffer guide shaft and the frame, and a position sensor that senses the position of the buffer guide shaft is fixedly mounted on the frame.

[0007] As a preferred technical solution, a cleaning and static elimination mechanism is provided between the pre-press buffer mechanism and the digital printer. The cleaning and static elimination mechanism includes a cleaning bracket fixedly installed on the frame. Two dust-adhesive rollers and two transfer rollers are rotatably mounted on the cleaning bracket. The two dust-adhesive rollers are disposed between the two transfer rollers and abut against the adjacent transfer rollers respectively. The label tape passes through the two dust-adhesive rollers. An static elimination guide shaft is installed on the frame between the cleaning bracket and the digital printer. An static elimination bracket is fixedly installed on the roller shaft of the static elimination guide shaft. An static eliminator is fixedly installed on the static elimination bracket. The label tape passes through the static eliminator and the static elimination guide shaft. A drying chamber is fixedly installed on the frame between the post-printing buffer mechanism and the digital printer. Several infrared heating tubes are installed inside the drying chamber. Two first ventilation fans for exhausting the gas inside the drying chamber and two second ventilation fans for drawing outside air into the drying chamber are fixedly installed on the drying chamber.

[0008] As a preferred technical solution, along the forward direction of the inlay backing paper, the inlay peeling transition unit includes an inlay unwinding shaft, two inlay peeling pre-traction rollers, an inlay photoelectric sensor, an inlay peeling knife, two inlay peeling post-traction rollers, and an inlay backing paper take-up shaft, which are sequentially arranged on the frame. The inlay photoelectric sensor and the inlay peeling knife are both fixedly installed on the frame, and the inlay unwinding shaft and the inlay backing paper take-up shaft are both rotatably installed on the frame.

[0009] As a preferred technical solution, the label peeling unit includes a label peeling blade fixedly mounted on the frame, the label peeling blade being disposed between the pressing assembly and the inlay peeling blade, and a label photoelectric sensor being disposed between the label peeling blade and the post-printing buffer mechanism.

[0010] As a preferred technical solution, the pressing assembly includes a pressing bottom roller and a pressing adhesive roller rotatably mounted on the frame, and the laminated RFID tag paper passes between the pressing bottom roller and the pressing adhesive roller.

[0011] The lamination process using the aforementioned RFID tag lamination equipment capable of online multi-color printing specifically includes the following steps: S1, The label peeling unit and the inlay peeling transition unit correspond to the original blank segment label backing paper; S2. The unwinding mechanism begins to unwind the label backing paper containing the label main material segment; S3. The die-cutting blade holder cuts the main label material segment into the label strip; S4. The digital printer prints the label tape online to obtain the label tape with the printed label; S5. The inlay peeling transition unit peels off the inlay layer and laminates it onto the original blank segment label backing paper. The original blank segment label backing paper laminated with the inlay layer is pulled to the label peeling unit. After distance calculation, the printed label is peeled off from the label backing paper and laminated onto the inlay layer. Then, after passing through the pressing assembly, the lamination of the RFID label paper is completed. The peeled label backing paper passes through the guide shaft assembly to form a new blank segment label backing paper. This process is repeated to continue the lamination of the subsequent RFID label papers. S6. When the original blank segment label backing paper is used up, the new blank segment label backing paper is pulled through the inlay peeling transition unit and returned to the label peeling unit. Repeat step S5 to form a continuous RFID label paper. S7. The RFID tag paper is continuously pulled through the read / write marking unit to read and write the chip in the inlay layer, and finally collected into a roll by the winding mechanism.

[0012] As a preferred technical solution, in step S1, the original label strip includes the blank label backing paper set at the front end and the label main material segment connected to the blank label backing paper. First, the blank label backing paper is wound up. The first end of the blank label backing paper passes through the die-cutting knife holder, digital printer, and label peeling unit in sequence. After being guided by the guide shaft group, it passes through the inlay peeling transition unit, label peeling unit, pressing assembly, and reading and writing marking unit in sequence and is fixed to the winding mechanism.

[0013] As a preferred technical solution, step S2 further includes correcting the deviation of the original label tape, and then guiding it into the die-cutting knife holder through the pressing and fixing guide device; Step S4 also includes pre-press buffering, pre-press cleaning, and pre-press static elimination processes; as well as post-press drying and post-press buffering processes. The distance calculation in step S5 is achieved by controlling the forward speed of the label backing paper and the inlay backing paper respectively through the label photoelectric sensor and the inlay photoelectric sensor; after being peeled off, the label backing paper passes through the guide shaft group, and then undergoes process correction to form a new blank segment label backing paper; Step S7 also includes marking RFID tags that fail to read or write.

[0014] By adopting the above technical solution, the beneficial effects of the present invention are as follows: The online multi-color printing RFID tag laminating equipment includes a die-cutting blade, a printer, a tag peeling unit, and an inlay peeling transition unit. The die-cutting blade processes the original tag material into a tag strip. Then, the digital printer prints the tag online. After passing through the tag peeling unit, the printed tag is first peeled from the tag backing paper. Then, after passing through the inlay peeling transition unit, the inlay layer is laminated to the tag backing paper. Finally, through the guide shaft assembly, the tag backing paper returns to the tag peeling unit for a second lamination of the printed tag. The entire process only requires one tag backing paper to complete the lamination of the entire RFID tag paper. There is no need to add auxiliary strips, corresponding take-up and unwinding components, and reverse transfer blades, which greatly simplifies the lamination process, integrates and simplifies the equipment, and greatly improves production efficiency and product qualification rate.

[0015] Because this invention includes two pressing and fixing guiding devices, the rolled original label tape is placed on the original label tape unwinding shaft, and the ends of the main label section and the blank label backing paper are both placed on the receiving platform. The main label section and the blank label backing paper are pressed down by the corresponding pressing and fixing guiding devices, and then the blank label backing paper is fed through the tape, so that the front end of the original label tape has the blank label backing paper. This allows the first peeled inlay and the printed label to be laminated onto the blank label backing paper. As the label backing paper moves forward, after the blank label backing paper is used up, the inlay and the printed label are laminated onto the label backing paper after the printed label is peeled off. Therefore, the RFID label paper lamination process only requires one label backing paper, thus simplifying the lamination process.

[0016] Because this invention includes a pre-press buffer mechanism, a post-press buffer mechanism, and a drying chamber, when the printer prints, the tension of the label tape changes, causing the buffer guide shaft to slide. By detecting the distance of the buffer guide shaft through a sensor, the main tape traction mechanism is controlled to speed up or slow down the traction speed of the label tape, thereby counteracting the tension changes of the label tape during printing. The infrared heating tube in the drying chamber dries the printing ink by heating it with infrared rays. At the same time, the first ventilation fan exhausts the gas in the drying chamber, and the second ventilation fan draws outside air into the drying chamber, forming an air circulation. By eliminating printing tension and quickly drying the labels, this invention solves the technical problem that existing technologies cannot achieve online multi-color printing. It also enables different content to be printed on two adjacent labels. This ability to print different labels is something that traditional printing cannot achieve. Attached Figure Description

[0046] S3, Die-cutting knife holder 55, cuts the main label material segment into label strip.

[0047] S4, digital printer 3 prints the label tape online to obtain a label tape with printed labels 4.

[0048] S5, the inlay peeling transition unit peels off the inlay layer 5 and laminates it onto the original blank segment label backing paper 6. The original blank segment label backing paper 6 with the inlay layer 5 laminated is pulled to the label peeling unit. After distance calculation, the printed label 4 is peeled off from the label backing paper 2 and laminated onto the inlay layer 5. Then, after passing through the pressing assembly, the lamination of the RFID label paper 7 is completed. The peeled label backing paper 2 forms a new blank segment label backing paper 6 after passing through the guide shaft assembly. This process is repeated to continue the lamination of subsequent RFID label paper 7.

[0049] S6. When the original blank segment label backing paper 6 is used up, the new blank segment label backing paper 6 is pulled through the inlay peeling transition unit and returned to the label peeling unit. Repeat step S5 to form a continuous RFID label paper 7.

[0050] S7. Continuous RFID tag paper 7 is pulled through the read and write tag unit to read and write the chip in the inlay layer 7, and finally collected into a roll by the winding mechanism.

[0051] Step S1: The original label tape includes a blank label backing paper 6 set at the front end and a label main material segment connected to the blank label backing paper 6.

[0052] Step S2 also includes correcting the deviation of the original label strip, and after correction, it enters the die-cutting knife holder 55 through the pressing and fixing guide device.

[0053] Step S4 also includes pre-press buffering, pre-press cleaning, and pre-press static elimination processes, as well as post-press drying and post-press buffering processes.

[0054] The distance calculation in step S5 is achieved by controlling the forward speed of the label backing paper 2 and the inlay backing paper 34 through the label photoelectric sensor 42 and the inlay photoelectric sensor 37, respectively. Both the label photoelectric sensor 42 and the inlay photoelectric sensor 37 use through-beam optical fibers. After being peeled off, the label backing paper 2 passes through the guide shaft assembly and then undergoes process correction to form a new blank segment of label backing paper 6.

[0055] Step S7 also includes marking the RFID tag paper 7 that fails to read or write.

[0056] In summary, this invention involves die-cutting the label and then printing it online. The printed label is first peeled from the label backing paper, then the inlay layer is laminated onto the label backing paper, and finally the printed label is laminated a second time. The entire process only requires one label backing paper to complete the lamination of the entire RFID tag. Because the lamination process is greatly simplified, not only is the equipment integrated and simplified, but production efficiency and product qualification rate are also greatly improved.

The RFID tag composite device capable of online multi-color printing according to claim 5, characterized in that, The label peeling unit includes a label peeling blade fixedly mounted on the frame. The label peeling blade is disposed between the pressing assembly and the inlay peeling blade. A label photoelectric sensor is disposed between the label peeling blade and the post-printing buffer mechanism.

7. The RFID tag composite device capable of online multi-color printing according to claim 6, characterized in that, The pressing assembly includes a pressing bottom roller and a pressing adhesive roller rotatably mounted on the frame, and the laminated RFID tag paper passes between the pressing bottom roller and the pressing adhesive roller.

8. The composite process using the RFID tag composite equipment capable of online multi-color printing as described in any one of claims 1-7, characterized in that, Specifically, the steps include the following: S1, The label peeling unit and the inlay peeling transition unit correspond to the original blank segment label backing paper; S2. The unwinding mechanism begins to unwind the label backing paper containing the label main material segment; S3. The die-cutting blade holder cuts the main label material segment into the label strip; S4. The digital printer prints the label tape online to obtain the label tape with the printed label; S5. The inlay peeling transition unit peels off the inlay layer and laminates it onto the original blank segment label backing paper. The original blank segment label backing paper laminated with the inlay layer is pulled to the label peeling unit. After distance calculation, the printed label is peeled off from the label backing paper and laminated onto the inlay layer. Then, after passing through the pressing assembly, the lamination of the RFID label paper is completed. The peeled label backing paper passes through the guide shaft assembly to form a new blank segment label backing paper. This process is repeated to continue the lamination of the subsequent RFID label papers. S6. When the original blank segment label backing paper is used up, the new blank segment label backing paper is pulled through the inlay peeling transition unit and returned to the label peeling unit. Step S5 is repeated to form continuous RFID label paper. S7. The RFID tag paper is continuously pulled through the read / write marking unit to read and write the chip in the inlay layer, and finally collected into a roll by the winding mechanism.

9. The composite process of the RFID tag composite device capable of online multi-color printing according to claim 8, characterized in that, Step S1: The original label tape includes the blank label backing paper set at the front end and the label main material segment connected to the blank label backing paper. First, the blank label backing paper is wound up. The first end of the blank label backing paper passes through the die-cutting knife holder, digital printer, and label peeling unit in sequence. After being guided by the guide shaft group, it passes through the inlay peeling transition unit, label peeling unit, pressing assembly, and reading and writing marking unit in sequence and is fixed to the winding mechanism.

10. The composite process of the RFID tag composite device capable of online multi-color printing according to claim 8, characterized in that, Step S2 also includes correcting the deviation of the original label tape, and after correction, it enters the die-cutting knife holder through the pressing and fixing guide device; Step S4 also includes pre-press buffering, pre-press cleaning, and pre-press static elimination processes; as well as post-press drying and post-press buffering processes. The distance calculation in step S5 is achieved by controlling the forward speed of the label backing paper and the inlay backing paper respectively through the label photoelectric sensor and the inlay photoelectric sensor; after being peeled off, the label backing paper passes through the guide shaft group, and then undergoes process correction to form a new blank segment label backing paper; Step S7 also includes marking RFID tags that fail to read or write.
