Description

Technical Field

[0001] This invention relates to the field of coding equipment technology, and more particularly to an NFC anti-counterfeiting label coding device. Background Technology

[0002] NFC anti-counterfeiting tags are a smart anti-counterfeiting method based on near-field communication technology. By embedding a unique, uncopyable chip ID and an encrypted verification mechanism, they enable product authenticity identification, traceability, and brand interaction. They offer advantages such as high security, ease of use, and multi-functional expansion, and are widely used in high-value product sectors such as luxury goods, pharmaceuticals, and alcoholic beverages. NFC anti-counterfeiting tags require a coding device to write unique identity information and encrypted data into the NFC chip. Through this coding device, companies can ensure that each NFC anti-counterfeiting tag possesses an uncopyable digital identity, providing a reliable data foundation for subsequent consumer verification and traceability systems.

[0003] Traditional equipment is equipped with only a single fixed write dock, which cannot simultaneously write multiple tags in parallel. Furthermore, the write dock position is fixed, making it difficult to adapt to tags with different chip layouts. This results in cumbersome changeovers, limited production capacity, and a lack of automatic feeding and precise synchronization control mechanisms, easily leading to tag misalignment, missed writes, or duplicate writes, affecting production consistency and yield. Therefore, this invention proposes an NFC anti-counterfeiting tag writing device to solve the problems mentioned in the background. Summary of the Invention

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing an NFC anti-counterfeiting label coding device.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: An NFC anti-counterfeiting label writing device includes a device table, an operation panel and a digital display panel integrated on the device table, a writing station fixed on the device table surface, the writing station for holding the label to be written, a plurality of NFC writing terminals arranged below the writing station, the writing station surface is a transparent glass plate, the operation panel is signal connected to the NFC writing terminals, and performs the writing of label data through the transparent glass plate; The equipment base is equipped with a feeding mechanism and a loading mechanism on the left and right sides, respectively. The feeding mechanism and the loading mechanism are used for automatic feeding of the label tape. The loading mechanism is equipped with a guide mechanism mounted on the equipment table at the rear side. The guide mechanism is used to guide the label tape to move along a preset path. The feeding mechanism is equipped with an adjustment mechanism mounted on the equipment table at the front side. The adjustment mechanism is used to adjust the position of the label tape in the width direction laterally.

[0006] Preferably, photoelectric sensors corresponding to the unloading mechanism and the loading mechanism are installed on the lower left and right sides of the equipment table. The photoelectric sensors are used to detect whether the label is in place and output signals to control the start and stop of the drive device in the loading mechanism and the unloading mechanism.

[0007] Preferably, the device table is equipped with a slide rail located under the coding station, and a plurality of NFC coding terminals are slidably mounted on the slide rail, and multiple NFC coding terminals can be mounted on the slide rail.

[0008] Preferably, the equipment table is a metal frame structure with supporting legs, and an anti-static layer is provided on the tabletop. The equipment table integrates a PLC controller and a power module that are connected to the operation panel.

[0009] Preferably, both the unloading mechanism and the loading mechanism are equipped with a drive device, and both the unloading mechanism and the loading mechanism include a roll shaft driven by the drive device. The loading mechanism is equipped with a magnetic powder brake to maintain constant tension of the label tape.

[0010] Preferably, the guiding mechanism consists of a pair of parallel limiting rollers, with the outer periphery of the rollers covered with flexible material for clamping and guiding the label tape to run smoothly.

[0011] Preferably, the adjustment mechanism includes a transverse slide rail, a slider, and a manual adjustment knob, which allows for stepless transverse displacement of the label tape position.

[0012] Preferably, the photoelectric sensor is a reflective infrared sensor, which is respectively set at the inlet of the loading station and the outlet of the unloading station. When the leading edge or trailing edge of the label is detected to reach the preset position, a position signal is sent to the control system to trigger the loading mechanism to start the roll and the unloading mechanism to stop unloading.

[0013] Preferably, the digital display panel is an LED display screen, which is connected to the control motherboard inside the equipment table via a signal line. Its display content is synchronously driven and updated by the writing command triggered by the operation panel.

[0014] Compared with the prior art, the beneficial effects of the present invention are as follows: 1. The present invention has a compact overall structure and reasonable layout, fully integrating the concepts of automated control and modular design, and has many outstanding advantages. The equipment adopts a structure that combines a transparent table and a slide rail below, which allows multiple NFC writing terminals to be flexibly installed and their positions adjusted along the slide rail. This not only facilitates the adaptation of different tag chip layouts, but also enables multiple tags to be written at the same time, significantly improving work efficiency. Through the orderly cooperation of the feeding mechanism, guiding mechanism, adjusting mechanism and unloading mechanism, the tag tape maintains stable tension and accurate path during the conveying process, effectively preventing deviation or jamming. 2. The equipment of this invention operates based on a closed-loop control system composed of photoelectric sensors and programmable controllers. It can automatically start and stop the feeding action according to the label's position status, ensuring accurate coding timing and avoiding empty writing or misalignment. The adjustment mechanism supports stepless lateral adjustment, quickly adapting to the coding requirements of different label specifications, enhancing the equipment's versatility and flexible production capabilities. The operation panel and independent digital display panel have clear division of labor: the former is used for command input, while the latter only displays key operating status. The interface is simple and intuitive, facilitating on-site monitoring. 3. The present invention features structural stability and electronic operating environment security. The internal electronic control system is highly integrated, and it can achieve high-precision and high-reliability continuous coding without relying on complex vision positioning or high-cost servo components. The ability of multiple coding terminals to work in parallel further enhances its practical value in the mass production of anti-counterfeiting labels. The overall solution ensures performance while also having good maintainability and production line compatibility. Attached Figure Description

[0017] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0018] Reference Figure 1-4An NFC anti-counterfeiting label writing device includes a device table 1, on which an operation panel 2 and a digital display panel 3 are integrated. A writing station 4 is fixed on the surface of the device table 1, which holds the labels to be written. Several NFC writing terminals 5 are arranged below the writing station 4. The surface of the writing station 4 is a transparent glass plate. The operation panel 2 is connected to the NFC writing terminals 5 and performs label data writing through the transparent glass plate. A feeding mechanism 6 and a feeding mechanism 7 are respectively installed on the left and right sides of the device table, which are used for automatic label tape feeding. A guide mechanism 8 is installed on the device table 1 behind the feeding mechanism 7, which guides the label tape to move along a preset path. An adjustment mechanism 9 is installed on the device table 1 in front of the feeding mechanism 6, which adjusts the position of the label tape in the width direction laterally. This NFC anti-counterfeiting label writing equipment achieves automation and precise control of label writing operations through a highly integrated modular layout. The equipment uses a metal frame structure (equipment table 1) as its base platform, rationally arranging the operation panel 2, digital display panel 3, writing station 4, and various actuators on it to form a compact and stable operating system. The writing station 4 features a transparent glass design, allowing for flexible configuration of multiple NFC writing terminals 5 on the lower slide rails. This facilitates adjustment of the writing points according to the label chip position and ensures visibility of the label position during the writing process, improving alignment reliability. The various functional units are spatially interconnected, forming a continuous and smooth process path from loading, guiding, writing to unloading, providing structural assurance for efficient and stable operation. Photoelectric sensors 10 are installed on the lower left and right sides of the equipment table 1, corresponding to the feeding mechanism 6 and the loading mechanism 7. The photoelectric sensors 10 are used to detect whether the label is in place and output signals to control the start and stop of the drive devices in the feeding mechanism 7 and the feeding mechanism 6. The photoelectric sensors 10 are reflective infrared sensors, respectively set at the inlet of the feeding station and the outlet of the feeding station. When the leading edge or trailing edge of the label is detected to reach the preset position, a position signal is sent to the control system, triggering the feeding mechanism 7 to start the roll and the feeding mechanism 6 to stop feeding. Both the feeding mechanism 6 and the feeding mechanism 7 are equipped with drive devices, and both the feeding mechanism 6 and the feeding mechanism 7 include a roll shaft driven by the drive device. The feeding mechanism 7 is equipped with a magnetic powder brake to maintain constant tension of the label tape. The equipment operation relies on a closed-loop feedback mechanism of photoelectric sensing and PLC control. Reflective infrared photoelectric sensors 10 are deployed at key nodes of the loading and unloading stations to monitor the label tape's position in real time. Based on this, the loading mechanism 7 is precisely triggered to start unwinding or the unloading mechanism 6 to pause rewinding, effectively avoiding coding misalignment or equipment idling caused by feeding ahead or behind. The loading mechanism 7 is equipped with a magnetic powder brake to maintain constant tension, and together with the flexible-coated limit roller guide mechanism 8, it ensures that the label tape moves smoothly without deviation during transportation. The adjustment mechanism 9 drives the horizontal slider through a manual knob, realizing rapid adaptation to labels of different widths or different chip positions, significantly improving the equipment's versatility. The entire control system issues commands from the operation panel 2, and the PLC coordinates the actions of each drive device to achieve timing synchronization and logical linkage of the coding process. The equipment table 1 is equipped with a slide rail located under the coding station 4. Several NFC coding terminals 5 are slidably mounted on the slide rail, and multiple NFC coding terminals 5 can be installed on the slide rail. The equipment table 1 has a metal frame structure with supporting legs, and the table surface is equipped with an anti-static layer. The equipment table 1 integrates a PLC controller and a power module connected to the operation panel 2. The guide mechanism 8 consists of a pair of parallel limit rollers, and the outer circumference of the rollers is covered with flexible material to clamp and guide the label tape to run smoothly. The adjustment mechanism 9 includes a horizontal slide rail, a slider, and a manual adjustment knob. The label tape position can be infinitely displaced laterally by adjusting the knob. The digital display panel 3 is an LED display screen. The digital display panel 3 is connected to the control main board inside the equipment table 1 through a signal line. Its display content is synchronously driven and updated by the coding command triggered by the operation panel 2. While ensuring high-precision coding, it also takes into account ease of operation and industrial applicability. The digital display panel 3, as an independent status indicator unit, only displays key operating parameters to avoid information redundancy and facilitate production line personnel to quickly grasp the equipment status. The anti-static table and enclosed internal electrical control layout enhance safety and anti-interference capabilities in the electronic tag production environment. The multi-write dock slide rail design supports parallel coding or multi-product switching, and can adapt to different product needs without changing hardware. The overall structure does not require complex visual recognition or high-cost servo systems, thus achieving reliable positioning, stable conveying and accurate data writing, and has good practicality, ease of maintenance and production line integration advantages.

Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
