Description

Technical Field

[0001] This invention relates to the field of near-field communication, and more particularly to an NFC tag writing detection system. Background Technology

[0002] Near Field Communication (NFC) tags are widely used and highly effective in the anti-counterfeiting market due to their unique User Identification (UID). NFC tags are widely used for product anti-counterfeiting, especially for tobacco packaging boxes, where anti-counterfeiting measures are achieved by attaching NFC tags to the tobacco packaging boxes.

[0003] The NFC tag writing detection system is a crucial component, used to write tag data and detect the written data. However, existing NFC tag writing detection systems cannot precisely adjust the distance between the writing device and the tag, as well as the distance between the tag and the product, during data writing, resulting in a large number of tag reading, writing, and labeling failures. In addition, existing NFC tag writing detection systems lack comprehensive tag detection capabilities; single NFC detection can only verify the validity of data and cannot identify physical damage to the tag. Summary of the Invention

[0041] The technical solution of the present invention will be further described in detail below with reference to the accompanying drawings and embodiments.

[0042] Figure 1 This is a schematic diagram of an NFC tag writing detection system provided in an embodiment of the present invention, as shown below. Figure 1 As shown, the NFC tag writing detection system is fixed on the conveying device 40. The conveying device 40 includes a conveying bracket 41 and a conveyor belt 42 mounted on the conveying bracket 41. Products are conveyed on the conveyor belt 42. The NFC tag writing detection system includes a labeling execution unit 10, a tag reinforcement unit 30, a tag detection unit 20, and a host computer. The labeling execution unit 10, the tag reinforcement unit 30, and the tag detection unit 20 are fixed sequentially on the conveying bracket 41 according to the product conveying order and are located above the conveyor belt 42. The labeling execution unit 10, the tag reinforcement unit 30, the tag detection unit 20, and the host computer are described in detail below.

[0043] The labeling execution unit 10 is used for writing and cutting label data. Specifically, the labeling execution unit 10 includes a lifting and adjusting component, a labeling machine body, and a label data writing mechanism. The lifting and adjusting component is fixed to the conveyor support 41 and is used to control the lifting and lowering of the labeling execution unit 10. The labeling machine body is fixed to the lifting and adjusting component, which adjusts the distance between it and the conveyor belt 42. The labeling machine body is used to transfer labels without written data to the label data writing mechanism. The label data writing mechanism is fixed to the labeling machine body and is used to generate label data and write the label data to the label. After writing, the label is cut and pasted onto the product conveyed by the conveyor belt 42.

[0044] The label reinforcement unit 30 includes a secondary label roller, which is fixed to the conveyor support 41 by a bracket and is used to crush the label on the product.

[0045] The tag detection unit 20 includes a detection platform, a multi-dimensional adjustment component, and a detection integration component, used for detecting tag data. The detection platform is fixed on the conveyor bracket 41 for mounting and securing the tag detection unit 20. The multi-dimensional adjustment component is fixedly mounted on the detection platform for multi-dimensional adjustment of the detection integration component, thereby achieving accurate tag detection. The detection integration component includes a visual detection component, an NFC tag detection module, and a QR code detection module. The visual detection component includes a camera, a light source, and an image processor for detecting the physical data of the tag. The NFC tag detection module verifies the integrity and accuracy of the tag data. The QR code detection module detects the QR code data of the tag.

[0046] The host computer is electrically connected to the labeling execution unit 10, the label reinforcement unit 30, and the label detection unit 20. It is used to control the labeling execution unit 10 to label the product, control the label reinforcement unit 30 to reinforce the label, and control the label detection unit 20 to detect the label.

[0047] The labeling execution unit 10 is described below. The labeling execution unit 10 provided in this embodiment of the invention is fixed on the production line. The production line conveys the products through the conveyor belt 42 to realize the writing of label data. Figure 2 , Figure 3 This is a schematic diagram of the structure of a labeling execution unit 10 provided in an embodiment of the present invention, as shown below. Figure 2 and Figure 3 As shown, the labeling execution unit 10 includes a lifting adjustment component, a labeling machine body, and a label data writing mechanism. The structure of each part of the labeling execution unit 10 will be described in detail below.

[0048] Height adjustment component 101 is used for height adjustment of the reading and writing device, such as... Figure 4As shown, the lifting adjustment component 101 enables accurate label delivery, data writing, and labeling operations. Specifically, it includes a fixed base 1011, a transmission rod 1012, and a sliding mounting block 1013. The lifting adjustment component 101 will be described in detail below.

[0049] The fixed base 1011 provides rigid support and bears the load of the equipment and moving components. Preferably, the fixed base 1011 is equipped with a horizontal adjustment bolt at the bottom to calibrate the level of the equipment and accommodate the installation requirements of production lines of different widths. The horizontal adjustment bolt at the bottom can calibrate the level of the equipment within a range of ±3°, solving the problem of equipment operation stability caused by uneven production line installation surfaces. The modular design of the fixed base 1011 shortens the installation and commissioning time of the equipment. The horizontal adjustment function ensures the stable operation of the equipment in complex production line environments, and the vibration of the equipment is controlled below 0.1 mm / s.

[0050] The transmission rod 1012 is fixed on the fixed base 1011, and can be a threaded rod.

[0051] The sliding mounting block 1013 is used to mount the equipment panel 102 and realize the vertical displacement of the equipment panel 102. The sliding mounting block 1013 is set on the transmission rod 1012 and can move up and down along the transmission rod 1012. Specifically, the sliding mounting block 1013 integrates a threaded hole that is compatible with the transmission rod 1012.

[0052] In some preferred embodiments, one end of the transmission rod 1012 is also provided with a hand crank 1016, which enables power input through manual operation. The transmission rod 1012 is connected to the sliding mounting block 1013 via a threaded pair. When the hand crank 16 is rotated, the manual rotational motion is converted into axial linear driving force, realizing the vertical displacement of the sliding mounting block 13, thereby achieving height adjustment. This application utilizes the self-locking characteristics of the threaded pair, such as using a trapezoidal thread or a pitch design that meets the self-locking conditions. After adjustment to the target height, it can be stably suspended without an additional locking device, ensuring a constant spatial position at the labeling station on the production line.

[0053] In some preferred embodiments, the lifting adjustment assembly 101 further includes two guide rods 1014, which are disposed on the fixed base 1011 and arranged parallel to the transmission rod 1012 to form a dual-axis guide, preferably disposed on both sides of the transmission rod 1012; the sliding mounting block 1013 is slidably mounted on the two guide rods 1014 through the internal guide hole, thereby forming a sliding fit between the two guide rods 1014 and the sliding mounting block 1013, constraining the axial rotational freedom of the sliding mounting block 13, eliminating the risk of tilting during the sliding process, and ensuring the verticality of the movement trajectory.

[0054] In some preferred embodiments, the lifting and adjusting assembly 101 further includes a device mounting block 1015, which adopts a modular design. One end is connected to the device panel 102 via fasteners, and the other end is fixedly connected to the sliding mounting block 1013, enabling rapid assembly and maintenance of the functional modules. More preferably, the device mounting block 1015 may be provided with a sliding adjusting block 10151, one end of which is fixedly connected to the device panel 102. The device mounting block 1015 slides on the sliding adjusting block 10151, thereby enabling horizontal adjustment of the device panel 102. Combined with a threaded pair, this achieves multi-dimensional adjustment of the device panel 102.

[0055] This application solves the labeling deviation problem caused by the mismatch between the distance between products of different specifications and the labeling machine through the multi-degree-of-freedom adjustment design of the lifting adjustment component 101. The structure adopts a bidirectional guide rail and a threaded locking mechanism, which can realize the distance fine adjustment within the range of 0-300mm, with an adjustment accuracy of ±0.5mm, to meet the labeling needs of diverse products.

[0056] The labeling machine body specifically includes an equipment panel 102, label tape 103, label feeding component 104, label transmission component 105, and recycling component 107. The following is a detailed description of the structure of each part of the labeling machine body.

[0057] The equipment panel 102 is used to fix the label feeding component 104, the label transmission component 105 and the label data writing mechanism 106. The equipment panel 102 is fixed on the sliding mounting block 1013 of the lifting adjustment component 101 and is located above the products on the conveyor belt 42. The distance between the equipment panel 102 and the products on the production line is adjusted by the up and down displacement of the sliding mounting block 1013 of the lifting adjustment component 101, which means the distance between the label and the product is realized, so as to achieve accurate labeling of the product.

[0058] The label tape 103 includes a backing paper tape and multiple labels set on the backing paper tape. The backing paper tape is blank. The multiple labels are affixed to the backing paper tape at intervals. Initially, no data is written to the labels. One end of the label tape 103 is fixed to the label feeding component 104, and the other end is fixed to the recycling component 107 after passing through the label transmission component 105 and the label data writing mechanism 106. It should be noted that after the label tape 103 enters the label data writing mechanism 106, the label data is written. After writing, the label is peeled off, and the peeled label is pasted on the product. The peeled backing paper tape is recycled to the recycling component 107. This process will be described in detail below.

[0059] The label feeding component 104 is used to fix the label tape 103. The label feeding component 104 is fixed on the equipment panel 102, and the label tape 3 is fixed on the label feeding component 104. Specifically, the label feeding component 104 has a paper loading shaft, and one end of the label tape 103 is fixed on the paper loading shaft. Initially, the label tape 103 is in a roll shape and fixed on the paper loading shaft. It can rotate around the paper loading shaft to realize the feeding of the label tape 103.

[0060] The label transfer component 105 is used for guiding the label tape 103 during transport. The label transfer component 105 is fixed to the equipment panel 102, preferably located below the label feeding component 104. Specifically, it may include multiple paper guide shafts to guide the label tape 3. The label tape 103 sequentially winds around the multiple paper guide shafts before entering the label data writing mechanism 106. This structure ensures that the label tape 3 will not experience wrinkles or misalignment during high-speed transport. Through the coordinated action of the lifting adjustment component 101 and the label transfer component 105, the label attachment position deviation can be controlled within ±1mm, effectively reducing downtime caused by label transport abnormalities.

[0061] The recycling component 107 is used for waste recycling. The recycling component 107 is fixed on the equipment panel 102 and recycles the peeled backing paper tape. Specifically, the recycling component 107 has a receiving shaft, and the other end of the label tape 103 is fixed on the receiving shaft. Preferably, the recycling component 107 also includes a guide shaft, which is set in front of the receiving shaft to guide the label tape 103 before it enters the receiving shaft.

[0062] The tag data writing mechanism 106 is used for writing tag data and peeling off tags. The tag data writing mechanism 106 is fixed on the device panel 102 and specifically includes a combination antenna 1062, an NFC reader / writer 1063, an adjustment plate 1061, and a tag cutting mechanism 1064. The tag strip 103 passes over the adjustment plate 1061. Tag data is written as the tag strip 103 passes over the combination antenna 1062 and the NFC reader / writer 1063. Then, the tag strip 103 passes over the tag cutting mechanism 1064 to peel off the tag. The adjustment plate 1061, NFC reader / writer 1063, combination antenna 1062, and tag cutting mechanism 1064 will be described in detail below.

[0063] The adjustment plate 1061 is tilted and fixed to the device panel 102. An NFC reader / writer 1063 and a combined antenna 1062 are mounted on the adjustment plate 1061. The NFC reader / writer 1063 generates tag data. Preferably, the tag data includes dynamic data and fixed data. The dynamic data includes, but is not limited to, production batch and timestamp, while the fixed data includes, but is not limited to, product code and specifications. A cross-validation mechanism between dynamic and fixed data ensures data integrity and improves data writing reliability. The combined antenna 1062 writes the tag data to the tag on the tag tape 103. More preferably, the combined antenna 1062 includes a first antenna and a second antenna. The first antenna writes the dynamic data to the tag, and the second antenna writes the fixed data. This dual-antenna design solves the problems of dynamic and static data conflict and excessive writing time when using a single antenna. The dual antennas are spaced 50mm apart, and with the synchronous control algorithm, the total writing time for a single tag is ≤200ms, meeting the high-speed operation requirements of the production line. When the host computer detects a data writing failure, the system triggers a background warning and immediately stops the labeling machine, solving the problem of bad labels being mixed in due to delayed fault response in traditional equipment. When a successful data writing is detected, the label tape 103 enters the label cutting mechanism 1064. The label cutting mechanism 1064 is located at the end of the adjustment plate 1061, specifically an acute-angle peeling blade, which peels the label off the label tape 103. The peeled label is then pasted onto the product, and the peeled backing paper tape is conveyed to the recycling component 107. Preferably, the label peeling angle is stabilized at 30°±2°, thereby improving the consistency of label separation.

[0064] In some preferred embodiments, the labeling execution unit 10 further includes a first touch terminal 109, which is electrically connected to the label data writing mechanism 6. The first touch terminal 109 is used to receive the label data issuance instruction input by the user and then send it to the label data writing mechanism 106 for label data generation and writing.

[0065] In some preferred embodiments, to achieve accurate label writing, precise monitoring of the label's position is required. The labeling execution unit 10 also includes a sensor 108, positioned between the label transmission component 105 and the label data writing mechanism 6, to monitor the label's positioning in real time. Through the coordinated control of the sensor 108 and the NFC reader / writer 1063, real-time feedback on label positioning detection and data writing results is achieved, thereby enabling accurate data writing.

[0066] In some preferred embodiments, the labeling execution unit 10 further includes an emergency stop button 1010, which can forcibly terminate the operation of the equipment in an emergency to ensure operational safety. Preferably, the emergency stop button 10 adopts a hardware-level trigger design with a response time of ≤10ms, enabling the equipment to stop quickly in an emergency.

[0067] The above is an introduction to the labeling execution unit 10. After the label is affixed, it is reinforced by the label reinforcement unit 30. The label reinforcement unit 30 includes a secondary labeling roller, such as... Figure 11 As shown, the label is fixed to the conveyor bracket 41 by a bracket and is used to crush the label on the product. After the label is reinforced, it needs to be inspected, so it enters the label inspection unit 20, which will be described below.

[0068] Figure 5 This is a schematic diagram of a tag detection unit structure provided in an embodiment of the present invention. Figure 6 This is a schematic diagram of the internal structure of a tag detection unit provided in an embodiment of the present invention, as shown below. Figure 5 and Figure 6 As shown, the tag detection unit 20 provided in this embodiment of the invention is fixed on the conveying equipment 40 of the production line. The conveying equipment 40 includes a conveying bracket 41 and a conveyor belt 42 disposed on the conveying bracket 41. The conveying bracket 41 is used to fix the conveyor belt 42 and the tag detection unit 20. The conveyor belt 42 is used to convey materials. The tag detection unit 20 of this application is used to detect NFC tags affixed to the materials on the conveyor belt 42. The tag detection unit 20 provided in this embodiment of the invention includes a detection platform, a multi-dimensional adjustment component, and a detection integration component. The following describes the process in conjunction with... Figures 5 to 8 As shown, the structure of each part of the tag detection unit 20 will be described in detail.

[0069] The detection platform 201 is used to fix the label detection unit 20. The detection platform 201 is fixed on the conveyor support 41 of the production line and is located above the material conveyed on the conveyor belt 42. Specifically, the detection platform 201 can be a chassis, including a left chassis 2012, a main chassis 2011, and a right chassis 2013 that are fixedly connected in sequence. The main chassis 2011 serves as the central hub and is connected to the left chassis 2012 and the right chassis 2013 by bolts. Specifically, a combination of mortise and tenon joints and bolt fastening can be used to form a symmetrical frame. The front end of the left chassis 2012 is equipped with a detection compartment, which houses the NFC tag detection module 206. The right chassis 2013 has a planned sensor cable routing path inside, realizing the structured integration of functional modules. The overall structure is welded from Q235 steel plate to ensure a rigid foundation. Preferably, the detection platform 201 also features an anti-resonance design: internal reinforcing ribs are added to ensure that the amplitude is ≤0.05mm at a production line cycle of 30 pieces / minute, guaranteeing the relative positional stability of the NFC tag detection module 206 and the tag on the product, i.e., the relative positional deviation is ≤±0.2mm. The box-type frame and anti-resonance design of this application reduce the mean time between failures (MTBF) of the equipment and lower maintenance costs.

[0070] The multi-dimensional adjustment component specifically includes a first adjustment module 202, a second adjustment module 203, a third adjustment module 204, and a fourth adjustment module 205. These four modules can be considered as a multi-dimensional adjustment mechanism used to achieve multi-dimensional adjustment of the integrated detection component, covering vertical height, horizontal position, and tilt angle adjustments to meet the multi-product angle detection requirements. The following is a description of the four adjustment modules.

[0071] The first adjustment module 202, specifically a lifting adjustment mechanism, is used to adjust the height of the label detection unit 20, ensuring that the NFC label detection module 206 of the label detection unit 20 and the label of the material are at a suitable detection distance, thereby achieving accurate label detection. Specifically, the first adjustment module 202 includes a lifting adjustment shaft 2021 and a lifting locking bushing 2022; one end of the lifting adjustment shaft 2021 is fixed to the top of the detection platform 201, and the lifting locking bushing 2022 is fitted onto the lifting adjustment shaft 2021, allowing it to rise or fall on the lifting adjustment shaft 2021 to adjust the height of the detection equipment.

[0072] In a preferred embodiment, in order to lock the lifting adjustment structure, the first adjustment module 202 further includes a lifting locking knob 2023. The lifting locking knob 2023 passes through the lifting adjustment shaft 2021 and the lifting locking bushing 2022. After adjusting the equipment height, the lifting locking knob 2023 is turned to fix the lifting locking bushing 2022 on the lifting adjustment shaft 2021, thereby realizing the vertical locking of the detection integrated component.

[0073] The second adjustment module 203, specifically a left-right adjustment structure, is used to adjust the left-right displacement of the label detection unit 20, so that the detection integration component of the label detection unit 20 is directly above the label of the material, achieving accurate label detection. Specifically, the second adjustment module 203 includes a sliding rail 2031 and a sliding table 2032; wherein, both ends of the sliding rail 2031 are fixed to the inner wall of the detection platform 201 and are set perpendicular to the lifting adjustment shaft 2021; the sliding table 2032 is fixedly connected to the lifting locking sleeve 2022, and a sliding block is provided at the bottom of the sliding table 2032, sliding on the sliding rail 2031. By sliding the sliding block on the sliding rail 2031, the left-right displacement adjustment of the detection integration component in the horizontal direction is achieved, thereby positioning the detection integration component of the label detection unit 20 directly above the label of the material.

[0074] In a preferred embodiment, to ensure stability during the sliding process, there are two sliding tracks 2031, which are connected by a sliding base plate 2033, which is fixed inside the detection platform 201. More preferably, in order to lock the left and right displacement, the second adjustment module 203 also includes two left and right locking knobs 2034. The left and right locking knobs 2034 pass through the sliding platform 2032 and the sliding base plate 2033. When the left and right positions are adjusted, the left and right locking knobs 2034 are turned to fix the sliding platform 2032 and the sliding base plate 2033, thereby locking the NFC tag detection module 206 in the horizontal direction.

[0075] The third adjustment module 204, specifically a rotary disk, is used to adjust the detection position of the NFC tag detection module 206 in the horizontal direction. The third adjustment module 204 is sleeved on the other end of the lifting adjustment shaft 2021, that is, the bottom of the lifting adjustment shaft 2021. In a preferred embodiment, the third adjustment module 204 has a central opening, which is used to fix the two components to the bottom of the lifting adjustment shaft 2021. Preferably, the third adjustment module 204 can be a crossed roller bearing, which allows the detection integrated component to rotate 360°, bearing radial and axial loads, thereby achieving rotational adjustment of the detection position of the detection integrated component.

[0076] The fourth adjustment module 205, specifically a rotating disk, is used to adjust the tilt angle of the detection surface of the NFC tag detection module 206, in conjunction with... Figure 9 As shown, the fourth adjustment module 205 and the third adjustment module 204 are fixedly connected and set perpendicular to the fourth adjustment module 5. The side of the fourth adjustment module 205 is fixedly connected to the side of the third adjustment module 204. In a specific example, the fourth adjustment module 5 specifically includes a fixed disk 2051 and a movable disk 2052. The left side of the fixed disk 2051 is fixedly connected to the third adjustment module 204, and the right side of the movable disk 2052 is fixedly connected to the NFC tag detection module 206. The contact surfaces of the fixed disk 2051 and the movable disk 2052 are... The device is equipped with interlocking racks to achieve a rotatable connection between the two. It can be understood that the fixed disk 2051 and the movable disk 2052 are driven by the interlocking of the racks on the sides. Thus, the NFC tag detection module 206 can be rotated 180° through the fixed disk 2051 and the movable disk 2052. In other words, the movable disk 2052 can be rotated 180° through the fixed disk 2051, and the NFC tag detection module 206 will also rotate 180° accordingly, thereby realizing the adjustment of the tilt angle of the detection surface of the NFC tag detection module 206.

[0077] The detection integration components specifically include a visual detection component, an NFC tag detection module, and a QR code detection module. The following is a detailed introduction to the three detection modules.

[0078] The visual inspection component (not shown in the figure) includes a camera, a light source, and an image processor. It is used to inspect the physical data of the label. Specifically, the camera and light source can be mounted above and to the side of the inspection station platform, aligned with the label affixing area of ​​the product. The image processor is electrically connected to the camera. The camera captures an image of the cigarette label under the illumination of the light source. The image processor analyzes and processes the image, checking whether the label's appearance, affixing position, etc., meet the requirements. Its working principle is to use image recognition technology to compare the captured image with a standard image to determine if any anomalies exist.

[0079] The NFC tag detection module is used to verify the integrity and accuracy of tag data. Specifically, the NFC tag detection module 206 is fixedly connected to the fourth adjustment module 205 and is positioned above the conveyor belt 42 to verify the tags attached to the materials on the conveyor belt 42. The NFC tag detection module 206 may include an RFID tag detection module and an NFC reader / writer module, forming a "physical + data" dual-dimensional detection. The RFID tag detection module detects the integrity of the tag antenna through magnetic field coupling, such as whether it is damaged or displaced, thereby performing a secondary physical inspection of the tag and improving accuracy. The NFC reader / writer module verifies the data format and encryption information, improving detection coverage and preventing physically damaged tags from flowing into the next process. Furthermore, the RFID tag detection module and the NFC reader / writer module can be integrated into the front detection chamber of the left chassis 2012, with the opening of the detection chamber facing the production line conveyor path to ensure signal coverage.

[0080] The QR code detection module (not shown in the figure) detects the QR code data of the label, collects the QR code information on the cigarette stick, and transmits it to the host computer for processing and comparison. The working principle is to convert the QR code image into digital information through optical scanning.

[0081] When the equipment is working, the host computer receives the results information collected by the vision inspection component, NFC tag detection module and QR code detection module. When there is a problem with any of the detections, the error information will be notified to the PLC in the form of an electrical signal. Its working principle is to summarize and analyze the signals of each detection device, generate control commands, and reject products or suspend the equipment.

[0082] In a preferred embodiment, the tag detection unit 20 further includes a sensor mechanism 7, combined with Figure 10As shown, a dual-sensor system is employed, specifically including an upstream sensor 2071 and a downstream sensor 2072. The upstream sensor 2071 and downstream sensor 2072 are fixed relative to each other on the inner wall of the detection platform 201. Corresponding sensor openings are provided on the inner wall of the detection platform 201. The upstream sensor 2071 and downstream sensor 2072 achieve detection through these sensor openings, thereby ensuring signal stability in complex environments. Further preferably, the dual sensors adopt a redundant design of "upstream trigger - downstream confirmation." Here, the upstream sensor 2071 is a diffuse reflective type with a detection distance of 50-300mm, responsible for initiating detection; the downstream sensor 2072 is a through-beam type with a response time ≤3ms, responsible for confirming the material passage status. The signals of both are verified through a logic AND gate, and validity is determined only when the two signals match, thereby reducing the false trigger rate. Furthermore, the sensor protection level reaches IP67, adapting to dusty workshop environments. In addition, the dual sensors can be fixed to the upstream and downstream ends of the production line respectively via adjustable brackets. The cable of the sensor mechanism 207 can be connected to the main control board through the protective conduit inside the right chassis to prevent dust interference.

[0083] In a preferred embodiment, the label detection unit 20 further includes a second touch terminal 208, which is disposed on the detection platform 201 and electrically connected to the detection integration component. Preferably, the second touch terminal 208 is embedded in the operating surface of the main unit housing 2011 to realize human-machine interaction. The second touch terminal 208 adopts an industrial touch screen and is designed with explosion-proof film and waterproof rubber ring to adapt to the oily environment of the workshop.

[0084] In a preferred embodiment, the tag detection unit 20 also includes an emergency stop button, which is integrated on the side of the left chassis 2012 and the right chassis 2013 and adopts a dual-channel design to simultaneously cut off the main circuit and the control circuit.

[0085] In a preferred embodiment, the label detection unit 20 further includes an alarm light 209, which is embedded in the top center of the main unit housing 2011 and directly connected to the internal control module via a hard wire. Specifically, the alarm light 209 is directly connected to the control module via a hard wire, and the trigger delay is ≤10ms. The PLC rejection signal is output with photoelectric isolation, and the entire process time from detecting abnormality to the rejection mechanism action is compressed to 50ms, which is 80% shorter than the traditional solution, thus avoiding the omission of abnormal products.

[0086] The above is an introduction to the structure of the NFC tag writing detection system provided in the embodiments of the present invention. Based on the understanding of its structure, the working process is described below.

[0087] First, adjust the equipment, which includes the following two parts:

[0088] The lifting adjustment component 101 is fixed to the production line. The distance between the labeling execution unit 10 and the product on the production line is adjusted by the lifting adjustment component 101 to ensure the accuracy of the labeling position and achieve accurate labeling of the product. The NFC tag tape 103 is loaded into the label feeding component 104. One end is fixed to the label feeding component 104, and the other end is guided by the tag transmission component 105, enters the tag data writing mechanism 106, and is fixed to the recycling component 107. It can be understood that in the initial state, the other end of the tag tape 3 needs to be fixed to the recycling component 107. Therefore, the first part of the tag tape 103 can be a blank section without a label, thus completing the fixing of the tag tape 3.

[0089] The label detection unit 20 is adjusted in multiple dimensions through a multi-dimensional adjustment mechanism. Specifically, the height is adjusted by the first adjustment module 202, the left and right displacement is adjusted by the second adjustment module 203, the rotation is adjusted by the third adjustment module 204, and the tilt is adjusted by the fourth adjustment module 205. This ensures that the position of the label detection unit 20 meets the detection angle and position of the product label, and the detection angle and position are precisely adjusted.

[0090] Then, the equipment is started and operated, which includes the following processes:

[0091] The operator selects NFC data and initiates the data issuance function via the first touch terminal 109, sending it to the host computer. The host computer generates a feeding command and sends it to the labeling execution unit 10, controlling the label feeding to begin. The sensor 108 detects the label's arrival status in real time. When the label arrives, the system activates the NFC reader / writer 1063 to interact with the backend data, generating dynamic and fixed data for a single label. The dynamic and fixed data are written separately via the combined antenna 1062. If data writing fails, the backend immediately issues a warning and stops the equipment, awaiting the operator to handle the defective label. If data writing is successful, the label cutting mechanism 1064 peels off the label, which is then directly affixed to the product. The waste strip is ultimately connected to the recycling component 107 for recycling.

[0092] After labeling, the product is conveyed to the label reinforcement unit 30 via the conveyor belt 42. The label on the product is reinforced by the rolling of the rollers in the label reinforcement unit 30. The reinforced product is then conveyed to the label detection unit 20 via the conveyor belt 42.

[0093] The dual sensors of the tag detection unit 20 enter standby mode. When the incoming material passes through the upstream sensor 2071, the detection signal is triggered. The detection integration component collects data and sends it to the host computer. The host computer receives the result information collected by the vision detection component, NFC tag detection module and QR code detection module. When there is a problem with any detection, the error information is notified to the PLC in the form of an electrical signal. Its working principle is to summarize and analyze the signals of each detection device, generate control commands, and reject products or suspend the equipment.

[0094] This invention provides an NFC tag writing and detection system, comprising a labeling execution unit, a tag reinforcement unit, a tag detection unit, and a host computer. The labeling execution unit utilizes a bidirectional guide rail and a threaded locking mechanism in its first adjustment module to achieve smooth lifting and lowering. Combined with the synergistic action of the tag transmission component and the tag data writing mechanism, this enables precise tag delivery, data writing, and labeling operations, improving tag reading and writing success rates. Furthermore, the tag detection unit's multi-dimensional adjustment component allows for multi-dimensional adjustment of the detection integration component, satisfying the detection angle and position of the product tag and enabling precise adjustment of these angles and positions. The detection integration component enables both physical and data-based dual-dimensional detection, thus providing comprehensive NFC tag detection, improving detection coverage, and preventing damaged tags from flowing into the next process.
