Description

Technical Field

[0001] The present invention belongs to the technical field of electronic tag detection, and in particular relates to an RFID electronic tag online detection method and device. Background Art

[0002] With the continuous development of RFID (Radio Frequency Identification) technology, RFID tags are widely used in logistics management, inventory control, asset tracking, access control, and other fields. RFID tags consist of a chip and an antenna. The chip stores information, while the antenna transmits and receives data via radio frequency signals. Based on their operating principles and power supply methods, RFID tags can be categorized into active, passive, and semi-active tags. Quality control of RFID tags is crucial during production and use, especially the label application process.

[0003] Patent application CN119706179B discloses an automatic conveying and detection device and detection method for RFID composite label paper. The key points of its technical solution are: including: a bracket plate, a rotating shaft, a conveyor belt, a drive motor, an active shaft, a circular plate, an inner ring, an outer ring, a detection component and a cross; the present invention can solve the following problems existing in the existing technology in the process of automatic conveying and detection of RFID composite label paper: the RFID composite label paper cannot be automatically discharged when it is detected that it is unqualified; the detector has a short scanning time for the RFID composite label paper, which cannot ensure that the detector can scan accurately and is prone to false detection; the present invention extends the scanning time of the RFID composite label paper to avoid false detection caused by too short scanning time; the present invention can ensure the stable transmission and accurate pasting of RFID composite label paper through the detection component; the invention recycles unqualified RFID composite label paper and realizes the automatic separation of unqualified label paper.

DETAILED DESCRIPTION

[0021] In order to make the technical means, creative features, objectives and effects achieved by the present invention easier to understand, the present invention is further described below in conjunction with specific implementation methods.

[0022] Example 1: Figures 1 to 6 As shown, an RFID electronic tag online detection device according to an embodiment of the present invention includes: A belt conveyor 1, wherein a bottom paper 11 is provided on one side of the belt conveyor 1, and the bottom paper 11 is used to carry the electronic tag and perform subsequent processing; A detection component, comprising a housing 4, wherein a detector 13 for detecting electronic tags is fixedly disposed inside the housing 4; The drive assembly includes a mounting frame 2 fixed above the belt conveyor 1, a linear module 3 fixed to the top of the mounting frame 2, a hydraulic cylinder 8 provided below the linear module 3, and a housing 4 fixed to the bottom of the telescopic rod of the hydraulic cylinder 8. The bottom of the housing 4 is provided with multiple groups of through holes 17 for adsorbing electronic tags. A connecting pipe 14 is fixed to the side wall of the housing 4. The end of the connecting pipe 14 away from the housing 4 is connected to a negative pressure pump (fixed to the top of the mounting frame 2, not shown in the figure, the connecting pipe 14 is a hose used to connect the housing 4 to the output end of the negative pressure pump); The gluing component is provided between the belt conveyor 1 and the bottom paper 11 and is used to apply glue to the electronic labels that have passed the inspection; The controller 5 is fixed on the top of the mounting frame 2. The controller 5, the linear module 3, and the hydraulic cylinder 8 are electrically connected. During operation, the RFID electronic tag to be tested is placed on the belt conveyor 1, and the belt conveyor 1 is used to convey the electronic tag to the bottom of the detection component and pause. The electronic tag is tested using the detector 13. The detector 13 is an RFID reader in the prior art, which is used to read and write the RFID electronic tag to ensure that the RFID electronic tag meets the detection requirements. During the detection process, the electronic tag is scanned by the detector 13 to detect whether the electronic tag can be read and written. If it cannot be read and written, the detector 13 transmits a signal that it cannot be read and written to the controller 5, and the controller 5 controls the belt conveyor 1 to start again to transfer the electronic tag for recycling; if it can be read and written normally, the detector 13 sends a signal that it can be read and written to the controller 5, and at this time the hydraulic cylinder 8 is controlled to extend downward, thereby driving the housing 4 and the detector 13 to move downward together, and at the same time starting the negative pressure pump, which evacuates the inside of the housing 4 through the connecting pipe 14, so that negative pressure is generated inside the housing 4, so that the housing 4 and the electronic tag can be connected. When in contact, the electronic tag can be adsorbed, and then the hydraulic cylinder 8 lifts the housing 4 and the electronic tag upward, and then the linear module 3 is started, and the hydraulic cylinder 8, the housing 4 and the electronic tag are synchronously moved laterally by the linear module 3 until they move to the top of the gluing component, and then the hydraulic cylinder 8 drives the electronic tag to move up and down, so that it contacts the gluing component, so as to glue the qualified electronic tag. After that, the linear module 3 continues to move, transports the electronic tag to the top of the base paper 11, and places the electronic tag on the base paper 11 by the hydraulic cylinder 8. At the same time, the negative pressure pump stops working to prevent the electronic tag from being peeled off from the base paper 11; Gluing is carried out after the test results come out, and only the electronic tags that pass the test are glued, which can improve the efficiency of adhesive use; electronic tags that fail the test can be directly transferred for recycling, and the process will not cause the adhesive to adhere to other equipment, so as to keep the working environment clean.

[0023] The glue coating assembly includes a support plate 9, which is fixed to the side wall of the belt conveyor 1. A storage box 15 for storing adhesive glue is fixed on the top of the support plate 9. A plurality of vertical tubes 18 are fixed on the top of the storage box 15. The bottom ends of the vertical tubes 18 are connected to the inner cavity of the storage box 15. Extrusion assemblies are symmetrically provided on both sides of the storage box 15. The adhesive inside the storage box 15 is squeezed out from the vertical tubes 18 through the extrusion assembly. The extrusion assembly includes an elastic membrane 26 fixed on the inner walls of both sides of the storage box 15. The elastic membrane A sealed space is formed between 26 and the inner wall of the storage box 15, and sleeves 19 are fixed to the outer walls of both sides of the storage box 15 respectively. A movable rod 21 is sealed and slidably mounted in the middle of the upper part of the sleeve 19. A spring 20 is sleeved on the upper part of the sleeve 19 to reset the movable rod 21. A transverse tube 27 is fixed to the side wall of the bottom of the sleeve 19, and the sleeve 19 and the elastic membrane 26 are connected through the transverse tube 27. A top rod 28 is sealed and slidably mounted in the middle of the sleeve 19, and a stop rod 31 is fixed in the middle of one end of the transverse tube 27 close to the sleeve 19; During operation, the housing 4 and the electronic tag are driven vertically downward by the hydraulic cylinder 8. The bottom end of the housing 4 contacts the top end of the movable rod 21 and presses the movable rod 21 downward, causing the movable rod 21 to move toward the inside of the sleeve 19, squeezing the air inside the sleeve 19, and then pushing the ejector rod 28 toward the inside of the storage box 15. The ejector rod 28 squeezes the inner wall of the elastic membrane 26, causing it to expand and become larger, so that the adhesive inside the storage box 15 can be squeezed out through the vertical tube 18, so that the adhesive is applied to the bottom of the electronic tag, making it convenient to stick the electronic tag to the base paper 11 later. In addition, using multiple vertical tubes 18 to apply adhesive dots on the electronic tag can save some adhesive. A curved baffle may be provided at the end of the ejector rod 28 so that the ejector rod 28 can better squeeze the elastic membrane 26 to expand it. In addition, the stop rod 31 is provided to limit the push rod 28 and prevent the push rod 28 from moving into the sleeve 19 so that the push rod 28 can laterally squeeze the elastic membrane 26 under the action of air pressure.

[0024] A movable plate 16 is provided above the storage box 15. A plurality of through holes 17 are evenly formed in the middle of the movable plate 16. The through holes 17 are matched one by one with the vertical tubes 18. The top ends of the vertical tubes 18 are movably inserted into the through holes 17. The top ends of the movable rods 21 are fixed to the side walls of the movable plate 16. During operation, when the movable plate 16 is not squeezed, the spring 120 supports the movable plate 16, so that the top of the vertical tube 18 is kept at a distance from the upper end surface of the movable plate 16, thereby protecting the top of the vertical tube 18 inside the through hole 17 and reducing the possibility of foreign matter directly falling onto the top of the vertical tube 18, thereby avoiding clogging of the vertical tube 18. In addition, when the housing 4 and the electronic tag are driven downward by the hydraulic cylinder 8 for gluing, the electronic tag first contacts the top of the movable plate 16, and then the movable rod 21 is pushed downward by the movable plate 16. At this time, the adhesive squeezed out of the vertical tube 18 first enters the through hole 17. By controlling the downward distance of the movable plate 16 by design, a distance is maintained between the top of the vertical tube 18 and the upper end surface of the movable plate 16. The top of the vertical tube 18 does not directly contact the electronic tag, but the adhesive in the upper through hole 17 contacts the electronic tag, which can effectively prevent the vertical tube 18 from directly contacting the electronic tag and causing damage to it.

[0025] A fixing tube 23 is fixed in the middle of the support plate 9, and a storage bottle 22 is threadedly connected to the bottom of the fixing tube 23. A conduit 24 is fixed to the lower part of the elastic membrane 26, and a one-way valve 25 is provided on the conduit 24. The end of the conduit 24 away from the elastic membrane 26 passes through the bottom of the storage box 15 and extends into the interior of the storage bottle 22. A one-way valve 29 is fixed to the side wall of the elastic membrane 26. During operation, the one-way valve 1 25 only allows the adhesive to enter the elastic membrane 26 through the conduit 24, and the one-way valve 29 only allows the adhesive inside the elastic membrane 26 to be discharged outward. When the elastic membrane 26 is squeezed by the push rod 28 to expand and become larger, the pressure inside the elastic membrane 26 increases, and the adhesive in the storage bottle 22 can be sucked into the elastic membrane 26 through the conduit 24. When the elastic membrane 26 contracts, the internal adhesive can be discharged into the inner cavity of the storage box 15 through the one-way valve 29, thereby automatically replenishing the adhesive to the inside of the storage box 15, which is convenient for continuous operation. In addition, the storage bottle 22 is detachably mounted on the fixed tube 23 through a threaded structure, which is convenient for disassembly, assembly and replacement of the storage bottle 22.

[0026] A second spring 30 is fixed between the inner wall of the elastic membrane 26 and the inner wall of the storage box 15; during operation, the second spring 30 is provided to enable the elastic membrane 26 and related structures to be quickly reset, shortening the reset time and thus improving work efficiency.

[0027] The side wall of the belt conveyor 1 is provided with a winding assembly, which includes a rotating shaft symmetrically arranged on both sides of the belt conveyor 1. A reel 10 is detachably mounted on both sides of the rotating shaft. The bottom paper 11 is wound on one side of the reel 10, and the free end of the bottom paper 11 is fixed to the other side of the reel 10; During operation, the motor, transmission wheel and transmission drive shaft on the side wall of the belt conveyor 1 rotate, thereby controlling the synchronous rotation of the shafts on both sides, and transferring the bottom paper 11 from the reel 10 on one side to the reel 10 on the other side, so that the electronic label can be evenly adhered to the bottom paper 11; further, a detection sensor can be set on the horizontal movement path of the hydraulic cylinder 8, such as a photoelectric sensor, which uses the photoelectric effect to emit light through the transmitter and receive the light through the receiver. When the hydraulic cylinder 8 passes, the light is blocked, thereby judging that the hydraulic cylinder 8 has passed. At this time, a signal can be sent to the control, thereby controlling the motor to rotate automatically, so as to drive the bottom paper 11 to automatically advance a certain distance, so as to facilitate the electronic label to be evenly adhered to the bottom paper 11.

[0028] A through groove is provided on the mounting frame 2 at a position corresponding to the linear module 3, and an I-shaped movable frame 7 is slidably arranged in the through groove. The top end of the hydraulic cylinder 8 is fixed on the lower end surface of the movable frame 7, and the movable frame 7 is fixed on the movable platform slidably connected to the bottom of the linear module 3; when working, the hydraulic cylinder 8 is connected to the bottom of the linear module 3 by setting the I-shaped movable frame 7, so that the hydraulic cylinder 8 can move stably with the linear module 3.

[0029] A trapezoidal support block 12 is fixed to the side of the support plate 9; during operation, the bottom paper 11 passes over the top of the support block 12, and the bottom paper 11 is supported by the support block 12, so that the electronic tag can be stably adhered to the bottom paper 11.

[0030] Example 2: Figure 1 and Figure 2 As shown, in contrast to Example 1, another embodiment of the present invention is as follows: a collection box 6 is provided below the end of the belt conveyor 1, and a guide platform 32 is provided in the collection box 6; during operation, the unqualified electronic tags are driven by the belt conveyor 1 to continue moving until they fall into the collection box 6 at the end of the movement and are collected; the guide platform 32 can be provided to guide the electronic tags, so that the electronic tags can contact the surface of the guide platform 32 in time after falling, and slide down the guide platform 32 into the collection box 6 to prevent the electronic tags from falling to other places.

[0031] like Figure 7 As shown, a method for online detection of RFID electronic tags is provided, which adopts the above-mentioned online detection device of RFID electronic tags and includes the following steps: S1, transport the electronic tag to the bottom of the detection component via the belt conveyor 1, and scan the electronic tag through the detector 13 to detect whether the electronic tag can be read and written; S2. If reading and writing are not possible, the electronic tag is transferred to the collection box 6 for recycling by the belt conveyor 1; S3. If reading and writing are normal, the electronic tag is adsorbed by the negative pressure pump, the connecting pipe 14 and the housing 4, and then the electronic tag is transferred to the top of the gluing component by the hydraulic cylinder 8 and the linear module 3. The qualified electronic tag is glued and finally pasted on the base paper.

[0032] Working principle: Place the RFID electronic tag to be tested on the belt conveyor 1, use the belt conveyor 1 to convey the electronic tag to the bottom of the detection component and pause, and use the detector 13 to detect the electronic tag. The detector 13 is an RFID reader in the prior art, which is used to read and write the RFID electronic tag to ensure that the RFID electronic tag meets the detection requirements; During the detection process, the electronic tag is scanned by the detector 13 to detect whether the electronic tag can be read and written. If it cannot be read and written, the detector 13 transmits a signal that it cannot be read and written to the controller 5. The controller 5 controls the belt conveyor 1 to start again and transfers the electronic tag to the collection box 6 for recycling; if it can be read and written normally, the detector 13 sends a signal that it can be read and written to the controller 5. At this time, the hydraulic cylinder 8 is controlled to extend downward, thereby driving the shell 4 and the detector 13 to move downward together, and at the same time starting the negative pressure pump. The negative pressure pump evacuates the inside of the shell 4 through the connecting pipe 14, so that a negative pressure is generated inside the shell 4 so that the shell 4 and the electronic tag can be read and written. When the sub-label contacts, it can absorb the electronic label, and then the hydraulic cylinder 8 lifts the housing 4 and the electronic label upward, and then the linear module 3 is started, and the hydraulic cylinder 8, the housing 4 and the electronic label are synchronously moved laterally by the linear module 3 until they move to the top of the gluing component, and then the hydraulic cylinder 8 drives the electronic label to move up and down, so that it contacts the gluing component, so as to glue the qualified electronic label. After that, the linear module 3 continues to move, transporting the electronic label to the top of the base paper 11, and the hydraulic cylinder 8 places the electronic label on the base paper 11, and at the same time the negative pressure pump stops working to prevent the electronic label from being peeled off the base paper 11; By setting the movable plate 16, when the movable plate 16 is not squeezed, the movable plate 16 is supported by the spring 120 so that there is a distance between the top of the vertical tube 18 and the upper end surface of the movable plate 16, so as to protect the top of the vertical tube 18 inside the through hole 17, reduce the possibility of external impurities directly falling into the top of the vertical tube 18, and avoid clogging of the vertical tube 18; when the housing 4 and the electronic tag are driven downward by the hydraulic cylinder 8 to apply glue, the electronic tag first contacts the top of the movable plate 16, and then the movable rod 21 is pushed downward by the movable plate 16. At this time, the adhesive squeezed out of the vertical tube 18 first enters the through hole 17. By designing and controlling the distance that the movable plate 16 moves downward, a distance is maintained between the top of the vertical tube 18 and the upper end surface of the movable plate 16. The top of the vertical tube 18 does not directly contact the electronic tag, but the adhesive in the upper through hole 17 contacts the electronic tag, which can effectively prevent the vertical tube 18 from directly contacting the electronic tag and causing damage; When the elastic membrane 26 is squeezed by the push rod 28 to expand, the pressure inside the elastic membrane 26 increases, and the adhesive in the storage bottle 22 can be sucked into the elastic membrane 26 through the conduit 24. When the elastic membrane 26 contracts, the adhesive inside can be discharged into the inner cavity of the storage box 15 through the one-way valve 29, thereby automatically replenishing the adhesive into the storage box 15 to facilitate continuous operation.
