Abstract
Description
Technical Field
[0001] This utility model relates to the field of tag equipment technology, specifically to an RFID tag equipment. Background Technology
[0002] In the modern printing industry, especially in packaging printing and label printing, the requirements for color registration accuracy are getting higher and higher. Color registration refers to printing different colored inks sequentially on the same substrate so that the pattern is accurately overlapped to form a complete and clear color image.
[0003] The printing plate for screen printing is made of screen mesh. The mesh openings in the image areas are open, while the mesh openings in the blank areas are blocked. During printing, ink is poured onto the screen, and then a squeegee is used to scrape the ink with a certain pressure and angle, causing the ink to pass through the mesh and transfer onto the label material to form an image label. The same method is used to print other color screen plates in sequence until all colors are printed.
[0004] RFID (Radio Frequency Identification) technology, as a non-contact automatic identification technology, has advantages such as fast reading, reusability, and large data storage capacity. It has been widely used in many fields such as logistics, retail, and anti-counterfeiting. Combining RFID technology with printed labels to form RFID tags can not only realize product identification and information storage, but also quickly obtain product information through RFID reading and writing devices.
[0005] However, current RFID tagging equipment lacks a stable moving mechanism, which makes it difficult for the squeegee to stably print ink onto the workpiece. This results in unstable color registration accuracy, affecting the generation of RFID tags and reducing production efficiency. In view of this, we propose an RFID tagging device.

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0026] Please see Figure 1 - Figure 4 This utility model provides a technical solution:
[0027] An RFID tag device includes a machine base 1. The bottom of the machine base 1 is equipped with a support and casters (shown in the figure but not labeled). The top of the machine base 1 is equipped with a conveyor 2. The upper surface of the conveyor 2 is clamped with a workpiece body 3. In addition, the machine base 1 and the conveyor 2 are provided in three sets. The conveyor 2 is a magnetic drive conveyor line, including components such as stators and movers. Since it is existing equipment in the prior art, it will not be described in detail here. The workpiece body 3 is clamped on its mover. There are multiple sets of workpiece bodies 3. The top of the machine base 1 is fixedly installed with a sliding column 4. There are four sets of sliding columns 4. The top of the sliding column 4 is fixedly installed with a top plate 5. The conveyor 2 adopts a magnetic drive conveyor line, which is composed of components such as stators and movers. By using the mover to clamp multiple sets of workpiece bodies 3, the workpiece body 3 is accurately transported along a preset path to the designated position of the target machine base 1, in preparation for the subsequent printing process.
[0028] In one embodiment of this utility model, a moving component 6 is provided at the top of the machine base 1. The moving component 6 includes an asynchronous motor 61. A threaded rod 62 is fixedly installed at the bottom output end of the asynchronous motor 61. The threaded rod 62 is rotatably installed at the top of the machine base 1. A square plate 63 is threaded onto the threaded rod 62. A horizontal hydraulic cylinder 64 is fixedly installed at the top of one end of the square plate 63. A rectangular plate 65 is fixedly installed at the piston end of the horizontal hydraulic cylinder 64. A vertical hydraulic cylinder 66 is fixedly installed at the other end of the rectangular plate 65. A fixed plate 67 is fixedly installed at the piston end of the vertical hydraulic cylinder 66. A limit rod 68 is fixedly installed inside the fixed plate 67. A slide bar 69 is sleeved at the bottom end of the limit rod 68. A pressing spring 610 is fixedly installed between the top end of the slide bar 69 and the fixed plate 67 at both ends. Spring 610 is sleeved on the outside of limit rod 68. Clamping plate 611 is fixedly installed at the bottom of slide bar 69. Scraper 612 is fixedly installed at the bottom of clamping plate 611. Printing plate 613 is fixedly installed at the other end of square plate 63. The bottom of scraper 612 slides against the inner bottom surface of printing plate 613. In addition, the moving component 6 is provided with three sets. The three sets of printing plates 613 are filled with ink for RFID tags of different colors. The printing plates 613 are made of screen, and the mesh of the screen is transparent, so as to better print RFID tags on multiple workpiece bodies 3 at the same time. In addition, there are two sets of horizontal hydraulic cylinders 64, limit rods 68, clamping springs 610 and clamping plates 611 in each set of moving component 6, so that the equipment body operates more stably and avoids affecting the accuracy of color printing.
[0029] In this embodiment, after the asynchronous motor 61 starts, it drives the threaded rod 62 to rotate. Since the square plate 63 and the threaded rod 62 are threadedly connected, under the rotation of the threaded rod 62, the square plate 63 moves up and down along the sliding column 4, simultaneously driving the horizontal hydraulic cylinder 64 to move up and down synchronously, changing the position of the horizontal hydraulic cylinder 64 in the vertical direction. When the horizontal hydraulic cylinder 64 starts, its piston end pushes the rectangular plate 65 to move laterally in the horizontal direction. Since the other end of the rectangular plate 65 is fixedly installed with the vertical hydraulic cylinder 66, the movement of the rectangular plate 65 drives the vertical hydraulic cylinder 66 to move laterally synchronously, realizing the adjustment of the horizontal position. When the square plate 63 moves downwards and approaches the workpiece body 3 to a certain distance, the vertical hydraulic cylinder 66 starts, and its piston end pushes the fixed plate 67 to move up and down. By controlling the extension and retraction of the piston end of the vertical hydraulic cylinder 66, the height of the fixed plate 67 can be finely adjusted to ensure that the components connected laterally can adapt to printing plates 613 of different sizes. Inside the fixed plate 67, the limiting rod 68 plays a guiding role. The slider 69 can slide up and down along the limiting rod 68. The spring 610 exerts a downward elastic force on the slider 69, causing the scraper 612 to adhere to the inner bottom surface of the printing plate 613. After the printing plate 613 has moved and adhered to the top surface of the workpiece body 3, the horizontal hydraulic cylinder 64 is activated. Its piston end drives the scraper 612 to scrape laterally towards the sliding column 4 on the inner bottom surface of the printing plate 613. At this time, since the printing plate 613 is made of screen mesh with open mesh, the movement of the scraper 612 allows the ink inside the printing plate 613 to pass through... The mesh is pressed onto the workpiece body 3 to complete the ink printing of the corresponding color, so that the ink is evenly applied and the printing quality is improved. After the printing of the current color is completed, the conveyor 2 transports the printed workpiece body 3 to the next machine 1 according to the program set by the controller. On the new machine 1, all the steps from transporting the workpiece to the printing operation are repeated. Through the printing plates 613 with ink for RFID tags of different colors on different machines 1, multiple colors are printed on the workpiece body 3, and finally, color printing is achieved.
[0030] In one embodiment of this utility model, an auxiliary component 7 is provided on the rectangular plate 65. The auxiliary component 7 includes a connecting rod 71. One end of the connecting rod 71 is fixedly installed on one end of the rectangular plate 65 near the horizontal hydraulic cylinder 64, and a wheel frame 72 is fixedly installed on the other end of the connecting rod 71. A roller 73 is rotatably installed inside the wheel frame 72. A sliding groove 74 is provided on the rectangular plate 63, and the roller 73 rolls and fits inside the sliding groove 74. In addition, two sets of connecting rod 71, wheel frame 72, roller 73 and sliding groove 74 are provided, which makes the operation of the equipment body more stable and avoids affecting the color printing accuracy.
[0031] In this embodiment, when the rectangular plate 65 moves under the push of the horizontal hydraulic cylinder 64, the connecting rod 71 moves synchronously, and the wheel frame 72 also moves, so that the roller 73 rolls synchronously inside the slide groove 74. The rolling cooperation between the roller 73 and the slide groove 74 makes the rectangular plate 65 move more smoothly and also plays a supporting role, thereby ensuring the movement stability of the scraper 612 during the printing process, and ultimately ensuring the high-precision operation of the equipment body during the color printing process.
