Description

[Technical Field]

[0001] This utility model relates to the field of printing equipment, and in particular to an electronic tag antenna manufacturing device using ultraviolet curing digital inkjet technology. [Background Technology]

[0002] Radio Frequency Identification (RFID) is an automatic identification technology that uses radio waves to read and transmit data. This technology allows for the automatic identification of target objects and the acquisition of relevant data through radio frequency signals without direct contact. An RFID system typically consists of three parts: tags, readers, and antennas. Both tags and readers require antennas, which act as a bridge between the reader and the tag, primarily responsible for transmitting and receiving radio waves.

[0003] However, existing RFID tag antennas are generally manufactured using screen printing technology. Therefore, a screen printing stencil needs to be made before manufacturing, which has drawbacks such as high cost, water pollution during stencil production, large size and low efficiency of screen-printed antennas, and suitability only for mass production of RFID tag antennas. Furthermore, current demands for RFID antennas are generally for miniaturization and small-batch customization, such as RFID tag antennas for small commodities in unmanned stores and other scenarios. Existing RFID tag antenna manufacturing equipment and methods are insufficient to meet these requirements. [Utility Model Content]

[0024] The technical solutions in the embodiments of this utility model will now be clearly and completely described in conjunction with the accompanying drawings.

[0025] It should be noted that all directional indications (such as up, down, left, right, front, back, etc.) in the embodiments of this utility model are only used to explain the relative positional relationship and movement of the components in a specific posture (as shown in the attached figure). If the specific posture changes, the directional indication will also change accordingly. Furthermore, descriptions involving "preferred," "second-best," etc., in this utility model are for descriptive purposes only and should not be construed as indicating or implying their relative importance or implicitly specifying the number of technical features indicated. Therefore, features defined as "preferred" or "second-best" may explicitly or implicitly include at least one of those features.

[0026] like Figure 1-6 As shown, an electronic tag antenna manufacturing equipment using UV-curable digital inkjet technology includes an organic platform 1, a substrate unwinding roller assembly 2, a finished product winding roller assembly 3, a metal film unwinding roller assembly 4, a metal film waste removal winding roller assembly 5, and a positioning film unwinding assembly 6. The substrate unwinding roller assembly 2 and the finished product winding roller assembly 3 are respectively positioned on the front and rear sides of the platform 1. A digital coating assembly 7 is located on the platform 1, behind the substrate unwinding roller assembly 2, and positioned on the upper side of the substrate for applying a UV hot stamping adhesive layer in the shape of an antenna onto the substrate. A positioning film unwinding assembly 6 is located on the platform 1, behind the digital coating assembly 7, and positioned on the upper side of the substrate for... A UV curing lamp assembly 8 is provided on the machine base 1 to fix the UV hot stamping adhesive layer on the substrate. A metal film pressing assembly 9 is provided on the machine base 1 behind the UV curing lamp assembly 8 to allow the substrate and metal film to pass through and to press the metal layer of the metal film onto the UV hot stamping adhesive layer. A metal film unwinding roller assembly 4 and a metal film waste discharge and rewinding roller assembly 5 are provided on the machine base 1 near the metal film pressing assembly 9. A positioning film pressing assembly 10 is provided on the machine base 1 behind the metal film pressing assembly 9 to allow the substrate and positioning film to pass through and to press the positioning film onto the substrate. A positioning film unwinding assembly 6 is provided on the machine base 1 near the positioning film pressing assembly 10.

[0027] When manufacturing RFID tag antennas, the substrate roll, metal film roll, and positioning film roll are respectively loaded onto the substrate unwinding roller assembly 2, the metal film unwinding roller assembly 4, and the positioning film unwinding assembly 6. During printing, the finished product take-up roller assembly 3 winds up and pulls the substrate on the machine base 1; when the substrate passes under the digital inkjet coating assembly 7, the digital inkjet coating assembly 7 performs digital variable inkjet printing on the substrate, spraying a UV hot stamping adhesive layer in the shape of the RFID tag antenna onto the substrate; subsequently, when the substrate passes under the UV curing lamp assembly 8, the UV curing lamp assembly 8 irradiates and cures the UV hot stamping adhesive layer; then, when the substrate enters the metal film pressing assembly 9, the metal film also enters the metal film pressing assembly 9, and the cured UV hot stamping adhesive layer on the substrate contacts the metal layer on the metal film, under the pressing action of the metal film pressing assembly 9. The metal layer on the metal film is cold-pressed onto the cured UV hot stamping adhesive layer. Simultaneously, the metal layer other than the UV hot stamping adhesive layer is recycled along with the metal film to the metal film waste removal and take-up roller assembly 5, thus forming an RFID tag antenna metal layer on the substrate. When the substrate enters the positioning film pressing assembly 10, the positioning film also enters the positioning film pressing assembly 10, and the positioning film contacts the RFID tag antenna metal layer of the substrate. Under the pressing action of the positioning film pressing assembly 10, the positioning film is pressed onto the substrate, facilitating the subsequent transfer of the RFID tag antenna through the positioning film. Finally, the finished product is wound onto the finished product take-up roller assembly 3. In this case, the substrate can be PVC, PP, PET, paper, or plastic; the metal layer in the metal film can be materials such as aluminum or silver.

[0028] In this case, during the printing process, the printhead of the digital spraying component 7 does not need to move to perform digital spraying printing. Only the substrate needs to move to perform digital variable spraying printing of the UV hot stamping adhesive layer in the shape of the RFID tag antenna on the substrate, achieving the function of accurately spraying and printing small antenna shape patterns. The digital spraying component 7 can also be equipped with multiple printheads, which can simultaneously spray and print multiple UV hot stamping adhesive layers in different RFID tag antenna shapes, realizing the function of simultaneously producing RFID tag antennas of different shapes. It also has the advantages of fast production speed, small batch production with a minimum order of one, and online small batch quick switching production of different antenna shapes. At the same time, the printhead of the digital spraying component 7 uses UV curing adhesive, which can be cured by irradiation by the UV curing lamp component 8 without high temperature drying. Moreover, the metal layer on the metal film can be imprinted onto the UV hot stamping adhesive layer of the substrate through cold hot stamping to form the metal layer of the RFID tag antenna, which greatly reduces the overall size of the equipment.

[0029] like Figure 5-6As shown, the digital inkjet coating assembly 7 includes a coating frame 71 mounted on the machine base 1 for the passage of the substrate. A vertical motion mechanism 72, with its moving end moving vertically, is located on the upper side of the substrate on the coating frame 71. A printing carriage 73 is mounted on the moving end of the vertical motion mechanism 72, and at least one digital printhead 74 is mounted on the printing carriage 73. Before printing, the printing height of the printing carriage 73 is adjusted by the vertical motion mechanism 72. The adjustable height of the printing carriage 73 also facilitates the passage of the substrate during installation. After the height of the printing carriage 73 is adjusted, the printing carriage 73 does not need to move during the printing process; the substrate movement allows for precise printing of the UV hot stamping adhesive layer in the shape of an RFID tag antenna. Multiple digital printheads 74 using digital variable inkjet technology can be installed in the printing carriage 73, enabling simultaneous high-precision printing of multiple UV hot stamping adhesive layers in different RFID tag antenna shapes.

[0030] like Figure 4-6 As shown, a longitudinal motion mechanism 75 is located on the upper side of the substrate on the spraying frame 71, with its moving end moving in the front-to-back direction. A support plate 76 is mounted on the moving end of the longitudinal motion mechanism 75, which moves with the longitudinal motion mechanism 75 to the underside of the printing carriage 73. The support plate 76 contains an ink pad 77 that supports the digital printhead 74. After the printing carriage 73 is sprayed and printed, the vertical motion mechanism 72 moves the printing carriage 73 upward to a preset position. Subsequently, the longitudinal motion mechanism 75 moves the support plate 76 to the underside of the printing carriage 73, placing the digital printhead 74 on the printing carriage 73 within the ink pad 77 of the support plate 76, thus providing moisture and protection for the digital printhead 74.

[0031] like Figure 5-6 As shown, a printhead scraper 715 for cleaning the digital printhead 74 is provided on the carrier tray 76 on the side facing the direction of movement of the ink pad 77. During the process of the longitudinal motion mechanism 75 moving the carrier tray 76 to the underside of the printing carriage 73, the printhead scraper 715 scrapes away residual adhesive on the digital printhead 74 to protect it. A carrier tray groove 714 is provided on the upper side of the carrier tray 76, and both the ink pad 77 and the printhead scraper 715 are located within the groove. A waste ink discharge nozzle 716 communicating with the groove is provided on the lower side of the carrier tray 76. The adhesive scraped away by the printhead scraper 715 is guided into the carrier tray groove 714 and finally discharged outside the machine 1 through the waste ink discharge nozzle 716. A protective plate 717 is connected to the lower side of the carrier tray 76 to protect the carrier tray 76 and the waste ink discharge nozzle 716.

[0032] like Figure 1 and Figure 5-6As shown, the digital printhead 74 is equipped with a first ink cartridge 711, and the printing carriage 73 is equipped with a second ink cartridge 712 connected to the first ink cartridge 711. The machine 1 contains a third ink cartridge 713 and an ink pump connected between the third ink cartridge 713 and the second ink cartridge 712. When adding UV-curing adhesive, simply load the UV-curing adhesive into the third ink cartridge 713. The ink pump will then deliver the adhesive from the third ink cartridge 713 to the second ink cartridge 712, which in turn delivers the adhesive to the first ink cartridge 711 for the digital printhead 74 to spray and print, simplifying the adhesive addition process.

[0033] like Figure 4-6 As shown, the spraying frame 71 includes side panels 78 disposed on both sides of the machine base 1. A vertical connecting plate 79 and a horizontal connecting plate 710 are provided between the side panels 78 to allow the substrate to pass through from the bottom. The horizontal connecting plate 710 is disposed on the lower front side of the vertical connecting plate 79. The longitudinal motion mechanism 75 is disposed on the rear side of the vertical connecting plate 79 and on the bottom surface of the horizontal connecting plate 710. This allows the vertical connecting plate 79, the printing carriage 73, the longitudinal motion mechanism 75, and the carrier plate 76 to be better disposed on the machine base 1, and to better coordinate their movements to protect the digital printhead 74.

[0034] like Figure 1-2 As shown, the UV curing lamp assembly 8 includes a UV lamp holder 81 mounted on the machine base 1 for the substrate to pass through. UV curing lamps 82 are respectively provided on the front and rear sides of the UV lamp holder 81. When the substrate passes through the UV curing lamp assembly 8, the UV curing lamps 82 irradiate and cure the antenna-shaped UV hot stamping adhesive layer, accelerating the curing speed of the UV hot stamping adhesive layer and facilitating the subsequent cold hot stamping of the metal layer.

[0035] like Figure 1-3 and Figure 6 As shown, the machine base 1 has extension plates 11 extending backward on both sides of the rear side. The metal film unwinding roller assembly 4, the metal film waste removal winding roller assembly 5, the positioning film unwinding assembly 6, the metal film pressing assembly 9 and the positioning film pressing assembly 10 are respectively arranged between the two extension plates 11. The finished product winding roller assembly 3 is arranged on the lower side of the rear side of the machine base 1, so that each roll of material is more tightly arranged on the machine base 1.

[0036] like Figure 1-3As shown, the metal film bonding assembly 9 includes a metal film active pressure roller 91 disposed between two extension plates 11 and a metal film driven pressure roller 92 that cooperates with the metal film active pressure roller 91 for pressing. When cold stamping a metal layer on a UV hot stamping adhesive layer shaped like an RFID tag antenna, the metal film active pressure roller 91 rotates actively and cooperates with the metal film driven pressure roller 92, allowing the substrate and the metal film to pass between the metal film active pressure roller 91 and the metal film driven pressure roller 92, so that the metal layer on the metal film is bonded to the UV hot stamping adhesive layer of the substrate under pressure. The metal film driven pressure roller 92 is equipped with a metal film driven roller heating tube 93, which heats the metal film driven pressure roller 92, which can improve the adhesion effect of the metal layer stamping on the UV hot stamping adhesive layer. A metal film driven roller temperature sensor 94 is provided on the extension plate 11 near the metal film driven pressure roller 92 to better regulate the temperature of the metal film driven pressure roller 92 and avoid excessive heating temperature affecting the adhesion effect of the metal layer.

[0037] like Figure 3 As shown, a film-tearing roller 12 is connected between the two extension plates 11 and positioned between the metal film pressing assembly 9 and the positioning film unwinding assembly 6. The film-tearing roller 12 can better separate the substrate and the waste metal film.

[0038] like Figure 1-3 As shown, the positioning film pressing assembly 10 includes a positioning film active pressure roller 101 disposed between two side extension plates 11 and a positioning film driven pressure roller 102 that cooperates with the positioning film active pressure roller 101 for pressing. When the positioning film is pressed onto the substrate, the active pressure roller 101 of the positioning film rotates actively and cooperates with the driven pressure roller 102 of the positioning film, so that the substrate and the positioning film pass between the active pressure roller 101 and the driven pressure roller 102 of the positioning film, connecting the substrate and the positioning film, and adhering the RFID tag antenna metal layer on the substrate to the positioning film. This makes it easier to separate the antenna metal layer from the substrate by tearing off the positioning film when transferring the antenna later. The driven pressure roller 102 of the positioning film is equipped with a heating tube 103 to heat the driven pressure roller 102 of the positioning film, which can improve the adhesion effect of the RFID tag antenna metal layer to the positioning film, making it easier to completely separate the RFID tag antenna metal layer from the substrate after tearing off the positioning film. The extension plate 11 is equipped with a temperature sensor 104 of the driven pressure roller 102 of the positioning film to avoid the heating temperature being too high and affecting the adhesion effect of the RFID tag antenna metal layer.

[0039] The above are merely preferred embodiments of this utility model and do not limit the patent scope of this utility model. Any equivalent structural transformations made based on the inventive concept of this utility model and the contents of this utility model specification and drawings, or direct or indirect applications in other related technical fields, are included within the patent protection scope of this utility model.
