[0002] RFID antenna is one of the core components of RFID tags, and its manufacturing process directly affects the performance of the tag. Traditional RFID antenna manufacturing methods include etching, electroplating and printing. Among them, printing has gradually become the mainstream process due to its low cost, good environmental protection, and suitability for flexible substrates.

[0003] During the manufacturing process of RFID antennas, the uniformity of conductive ink directly affects the performance of the antenna. In the prior art, conductive ink storage tanks usually adopt a central stirring method, that is, the agitator is located at the center of the ink tank, and the ink is mixed by rotating the stirring paddle. However, this stirring method has defects: on the one hand, central stirring can only make the ink in the central area of ​​the ink tank flow, and the ink in the edge area is difficult to fully mix, resulting in uneven distribution of conductive particles. In addition, for high-viscosity inks or nano-scale conductive particles, the effect of central stirring is even worse, and it is difficult to meet the production requirements of high-quality RFID antennas; on the other hand, stirring only in the center is prone to produce bubbles in the ink, affecting the printing quality.

[0043] The ink storage tank 1 is installed inside the printing press. A rotating shaft 141 is rotatably installed at the center of the ink storage tank 1. Several pairs of stirring components are installed on the surface of the rotating shaft 141 along the vertical direction.

The rotating shaft 141 is driven to rotate by the driving motor 14, and the stirring blades 142 on the rotating shaft 141 can rotate in the ink storage tank 1 filled with ink, thereby achieving the purpose of mixing the ink at the center of the ink storage tank 1.

[0044] The partition 2 is installed on the ink storage tank 1, and a shift guide 23 is installed on the inner surface of the partition 2. The shift guide 23 includes four pairs of inner grooves 231 and four pairs of outer protrusions 232, and the four pairs of inner grooves 231 and the four pairs of outer protrusions 232 are staggeredly installed on the inner wall of the partition 2, and the inner wall of the partition 2 is annular, and a ball is installed inside the shift guide 23, and the ball serves to reduce friction.

[0045] The synchronous plate 3 is rotatably installed at the mouth of the ink storage tank 1, and the end of the synchronous plate 3 is connected to the rotating shaft 141. A slider 32 is slidably installed inside the synchronous plate 3, and a synchronous shaft 33 is vertically and movably inserted on the slider 32. The side wall of the synchronous shaft 33 fits the shift guide 23. A stirring shaft 332 is installed at the bottom of the synchronous shaft 33, and the stirring shaft 332 is placed inside the ink storage tank 1. A connecting shaft 341 is movably inserted on the synchronous shaft 33, and the connecting shaft 341 is cross-shaped. A stirring motor 34 is installed at the end of the connecting shaft 341, and the stirring motor 34 slides horizontally above the synchronous plate 3; the stirring motor 34 drives the connecting shaft 341 connected to the output shaft to rotate, and the connecting shaft 341 can rotate with the synchronous shaft 33 at the bottom. At this time, the synchronous shaft 33 can drive the stirring shaft 332 to rotate, thereby achieving the purpose of stirring the outer layer of ink.

The guide wheel 521 slides on the limiting guide rail 5 to drive the synchronous shaft 33 to move vertically, and the synchronous shaft 33 drives the stirring shaft 332 to move downward at this time, thereby changing the stirring depth and improving the sufficient stirring. In the process of the stirring shaft 332 moving downward, the rocker arm 42 connected to the hexagonal fixing rod 4 will squeeze the insertion rod 421 inserted in the side wall of the stirring shaft 332 to slide outward, thereby further increasing the stirring range and improving the stirring efficiency.

[0047] like Figures 1 to 9 As shown, in a specific embodiment, four mounting ears 11 are evenly installed on the bottom of the ink storage tank 1, and mounting holes 111 are opened on the four mounting ears 11, and the mounting holes 111 are adapted to the mounting positions inside the printing machine. The mounting ears 11 and the mounting holes 111 are convenient for connection and installation with the printing machine. An observation window 12 is installed on the side wall of the ink storage tank 1, and scale lines are printed on the observation window 12. The content of the internal ink is convenient to be observed through the observation window 12, and the scale lines can more clearly display the content of the ink.

[0048] like Figures 1 to 9As shown, further, a cover plate 13 is installed on the housing of the driving motor 14. The cover plate 13 is arched, and the bottom of the cover plate 13 fits with the partition 2. The cover plate 13 and the partition 2 are installed by screws, and the cover plate 13 positions the position of the driving motor 14. A sealing gasket 21 is installed between the connection position of the partition 2 and the ink storage tank 1 and the connection position of the partition 2 and the cover plate 13. The sealing gasket 21 increases the sealing of the whole device. A notch 22 is opened on the partition 2. A locking bolt 221 is rotatably installed inside the notch 22. The locking bolt 221 is used to connect the ink storage tank 1 and the partition 2.

[0049] Embodiment 2:

[0050] The difference between Example 1 and this Example is that: Figures 1 to 9 When the locking cam 321 is unlocked, the locking cam 322 is unlocked and the locking cam 323 is unlocked, so that the locking cam 322 can be unlocked when the locking cam 323 is unlocked.

[0051] like Figures 1 to 9 As shown, in a specific embodiment, a slide plate 342 is installed on the outer shell of the stirring motor 34, and a positioning rod 343 is installed inside the slide plate 342 so as to be movable and penetrated. A mounting frame 344 is welded at the end of the positioning rod 343, and the end of the mounting frame 344 is interconnected with the side wall of the synchronous plate 3. The positioning rod 343 can assist the stirring motor 34 to slide synchronously along the synchronous plate 3. A positioning plate 331 is installed on the synchronous shaft 33, and the positioning plate 331 is placed above the slider 32. The positioning plate 331 positions the lowest position of the synchronous shaft 33 when it falls.

[0052] Embodiment 3:

[0053] The difference between Example 2 and this example is that: Figures 1 to 9As shown, the rocker arm 42 is in an inclined state, and a pressure plate 423 is sleeved on the plug rod 421 located in the inner cavity of the stirring shaft 332, and an extrusion spring 424 is sleeved on the plug rod 421. One end of the extrusion spring 424 is clamped on the pressure plate 423, and the other end of the extrusion spring 424 is clamped on the inner wall of the stirring shaft 332. During the sliding process of the plug rod 421, the plug rod 421 begins to slide toward the inner cavity of the stirring shaft 332, compressing the reset spring 412 at this time, and facilitating the reset operation later through the reset spring 412. A socket is provided at the bottom of the hexagonal fixing rod 4, and a synchronization rod 43 is inserted inside the socket. The synchronization rod 43 is in a vertical state, and the bottom of the synchronization rod 43 and the bottom of the inner cavity of the stirring shaft 332 are connected to each other. The synchronization rod 43 ensures that the hexagonal fixing rod 4 and the stirring shaft 332 output a vertical parallel sliding state.

[0054] like Figures 1 to 9 As shown, in a specific embodiment, the top of the hexagonal fixing rod 4 is movably inserted into the sliding cavity 411 opened inside the synchronous shaft 33, and a push plate 41 is installed at the connection between the hexagonal fixing rod 4 and the connecting shaft 341, and the push plate 41 slides in the sliding cavity 411, and a compression spring 424 is sleeved on the hexagonal fixing rod 4, one end of the compression spring 424 is clamped on the push plate 41, and the other end of the compression spring 424 is clamped on the top of the stirring shaft 332. When the stirring shaft 332 moves downward, the stirring shaft 332 can drive the synchronous shaft 33 to move, which affects the compression spring 424, and the compression spring 424 is convenient for resetting later.

[0055] like Figures 1 to 9 As shown, further, limit seats 51 are installed at both ends of the limit guide rail 5, the limit seat 51 is installed on the side wall of the synchronous plate 3, a guide rail 522 is slidably installed on the slide bar 52, and the guide rail 522 is welded to the side wall of the synchronous shaft 33, and a vertical rod 523 is installed on the slide bar 52, the vertical rod 523 is a telescopic rod, and the shell of the vertical rod 523 is installed on the shell of the stirring motor 34, the vertical rod 523 ensures that the slide bar 52 is in a vertical state, and during the rotation of the synchronous shaft 33, the position of the slide bar 52 is ensured not to change through the action of the guide rail 522.

[0056] The implementation principle of a printing device for producing RFID antennas of the present invention is as follows:

[0057] First, the coating required for printing is placed in the ink storage tank 1. When the coating is placed in the ink storage tank 1, in order to mix the ink more fully and reduce the generation of bubbles, the operator needs to start the drive motor 14 and the stirring motor 34 at the same time.

[0058] When the driving motor 14 starts to rotate, the driving motor 14 can drive the rotating shaft 141 to rotate, and the stirring blade 142 on the rotating shaft 141 can rotate in the ink storage tank 1 filled with ink, thereby achieving the purpose of mixing the ink at the center of the ink storage tank 1.

[0059] During the rotation of the rotating shaft 141, the connecting block 31 on the side wall of the rotating shaft 141 can drive the synchronous plate 3 to rotate periodically. At this time, the synchronous plate 3 drives the slider 32 on the surface to rotate, and the synchronous shaft 33 on the slider 32 rotates synchronously, and the stirring shaft 332 at the bottom of the synchronous shaft 33 rotates synchronously, so that the stirring shaft 332 can rotate on the outer layer of the ink storage tank 1 to synchronously mix the outer layer of ink. At this time, the stirring motor 34 drives the connecting shaft 341 connected to the output shaft to rotate, and the connecting shaft 341 can rotate the synchronous shaft 33 at the bottom. At this time, the synchronous shaft 33 can drive the stirring shaft 332 to rotate, so as to achieve a better stirring effect.

[0060] During the periodic rotation of the synchronous plate 3, the synchronous shaft 33 on the synchronous plate 3 rotates synchronously and periodically, and the synchronous shaft 33 always adheres to the surface of the shift guide rail 23. Since a plurality of inner grooves 231 and outer protrusions 232 are provided on the shift guide rail 23, the synchronous shaft 33 can be pushed to move back and forth toward the rotation center, thereby driving the stirring shaft to move toward the middle layer of the ink storage tank 1, stirring the ink in the middle layer, thereby improving the sufficient stirring.

[0061] And in the process of the synchronous shaft 33 moving toward the rotation center, the side wall of the slider 32 on the synchronous shaft 33 slides on the slide groove 321, and the slider 32 can slide along the limit rod 322 at this time. The slider 32 can compress the limit spring 323 at this time, and the compressed limit spring 323 is convenient for later resetting. The limit spring 323 ensures that the synchronous shaft 33 always has the force to move outward, ensuring that the synchronous shaft 33 can always fit the shift guide rail 23.

[0062] In the process of the slider 32 driving the synchronous shaft 33 to move, the slide bar 52 on the side wall of the synchronous shaft 33 can slide synchronously, and the guide wheel 521 at the end of the slide bar 52 can always slide along the limiting guide rail 5 at this time. Through the guiding effect of the limiting guide rail 5, the guide wheel 521 and the slide bar 52 at this time always have a tendency to move downward, and the synchronous shaft 33 connected to the slide bar 52 moves downward, and the synchronous shaft 33 drives the stirring shaft 332 to move downward. When the stirring shaft 332 moves downward, the stirring position changes at this time. By mixing and stirring at different heights, the sufficient stirring can be improved.

[0063] When the stirring shaft 332 moves downward, the flat plate 422 and the plug rod 421 on the side wall of the stirring shaft 332 move downward synchronously, so that at this time, one end of the rocker arm 42 has a downward force, and the other end is rotatably connected, so that at this time, the plug rod 421 is pushed to slide outward, and the plug rod 421 drives the flat plate 422 at the end to slide outward, and finally the length of the plug rod 421 on the stirring shaft 332 can be increased to further ensure the adequacy of the stirring.

[0064] During the sliding process of the plug rod 421, the plug rod 421 starts to slide toward the inner cavity of the stirring shaft 332, compressing the reset spring 412 at this time, and facilitating the reset operation later through the reset spring 412. When the stirring shaft 332 moves downward, the stirring shaft 332 can drive the synchronous shaft 33 to move, which affects the extrusion spring 424, and facilitates the reset operation later through the extrusion spring 424.
