Description

Technical Field

[0001] This invention relates to the technical field of QR codes, specifically to an intelligent identification system for verifying the authenticity of QR codes. Background Technology

[0002] QR codes were initially used in automobile manufacturing for tracking parts, and are now widely used for identification, anti-counterfeiting, shopping, and other applications. Also known as a two-dimensional barcode, a QR code is a pattern of bars and spaces arranged according to a specific geometric shape on a two-dimensional plane to record data symbols. QR codes are characterized by large information capacity, wide encoding range, strong fault tolerance, high decoding reliability, low cost, and ease of production. With the development of the internet and the widespread use of mobile devices, the application of QR codes in mobile devices is increasing. For example, QR code recognition is currently mainly achieved by installing QR code recognition applications on mobile devices. Specifically, users use the camera function of their mobile devices to photograph the QR code, and then use the QR code recognition application to identify the QR code, quickly obtaining the information stored in the QR code, and further enabling various functions such as one-click internet access, data download, location tracking, and online payment.

[0003] QR codes are now widely used for product anti-counterfeiting, anti-counterfeiting, and traceability. From coding to detection, the related software and hardware are mature and have high support, and people's acceptance of QR codes is also very high.

[0018] Compared with the prior art, the beneficial effects of the present invention are:

[0019] 1. The present invention proposes an intelligent identification system for verifying the authenticity of QR codes. By having a printing system and an identification system work together, the printing system can print a QR code image with a certain thickness, which increases the difficulty of counterfeiting. The identification system collects QR code information through a collection module and identifies the authenticity of the QR code information through the identification module, making the anti-counterfeiting effect of QR codes more significant.

[0020] 2. When the printing system prints a QR code, the printer prints the QR code on the printing paper. The paint needle then applies another layer of paint to the QR code pattern, increasing its thickness. During the paint application, the third lead screw is activated, causing it to rotate. This moves the connecting slider inside the connecting frame, controlling the lateral movement of the paint needle. The second motor is then activated, driving the second lead screw to rotate, which in turn moves the slider on the guide rail, controlling the longitudinal movement of the paint needle. This allows the thickness of the QR code to be increased according to a set pattern, resulting in higher automation and greater convenience.

[0021] 3. After a coating operation is completed, some paint will remain in the paint needle, which may cause dripping. To avoid contaminating the QR code or dripping onto the equipment, close the ball valve and then open the solenoid valve. The reflux pump will start and suck away the paint residue in the feed hole and paint needle, thus preventing paint dripping. Attached Figure Description

Detailed Implementation

[0030] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0031] Please see Figures 1 to 7 The present invention provides a technical solution: an intelligent identification system for verifying the authenticity of QR codes, characterized in that it includes a printing system and a recognition system;

[0032] The printing system includes a printing device that can control the thickness of the QR code print;

[0033] The identification system includes a central processing unit (CPU), which is connected to a display module, a storage module, a data acquisition module, and an identification module. The data acquisition module includes a data acquisition device and an information processing module, while the identification module includes a receiving unit, a comparison unit, and an extraction unit.

[0034] The printing device includes a frame 1, a printer 2 at one end of the frame 1, a conveyor belt 3 on the frame 1, two mounting plates 4 on the middle sides of the printer 2, guide rods 5 slidingly mounted on the mounting plates 4, a pressing push rod 6 mounted on the bottom surface of the guide rods 5, a base plate 7 at the bottom end of the pressing push rod 6, a set of vacuum suction cups 8 on the bottom surface of the base plate 7, a side plate 9 connected to the end of the guide rods 5, a threaded collar 10 in the middle of the side plate 9, a first motor 11 mounted on the side wall of the mounting plate 4, a first lead screw 12 connected to the output end of the first motor 11, and the first lead screw 12 and the threaded collar 10 connected by internal and external threads. When the QR code moves below the ink needle 25, the pressing push rod 6 extends, causing the base plate 7 to descend, and the vacuum suction cups 8 to pick up the printing paper. By controlling the start of the first motor 11 to drive the first lead screw 12 to rotate, the side plate 9 can move the guide rods 5, thereby positioning the QR code in the middle position, which is convenient for QR code positioning.

[0035] Two lifting plates 13 are mounted above the mounting plate 4. The lifting plates 13 and the mounting plate 4 are connected by a support push rod 14. A guide slide rod 15 is provided between the two lifting plates 13. A slider 16 is slidably mounted on the guide slide rod 15. A second motor 17 is mounted on the side wall of the lifting plate 13. The output end of the second motor 17 is connected to a second lead screw 18. The second lead screw 18 passes through the slider 16 and is connected to the threaded hole in the center of the slider 16. A connecting frame 19 is connected to the bottom of the slider 16. A connecting slider 20 is provided inside the connecting frame 19. Limit plates are provided on both sides of the connecting slider 20. The limit plates slide into the grooves on the inner side wall of the connecting frame 19, making the movement of the connecting slider 20 more stable. A third motor is mounted on one side wall of the connecting frame 19. The output end of the third motor 21 is connected to a third lead screw 22. The third lead screw 22 passes through the connecting slider 20 and is connected to the threaded hole in the middle of the connecting slider 20. The bottom of the connecting slider 20 is connected to a mounting post 23. The bottom of the mounting post 23 is provided with a mounting plate 24, and a paint needle 25 is mounted on the mounting plate 24. When applying paint, the third lead screw 22 is started and rotated, causing the connecting slider 20 to move inside the connecting frame 19, thereby controlling the lateral movement of the paint needle 25. This controls the start of the second motor 17 to rotate the second lead screw 18, thereby controlling the slider 16 to move on the guide slide 15, and further controlling the longitudinal movement of the paint needle 25. Thus, the thickness of the QR code can be increased according to the set pattern, which is more automated and more convenient.

[0036] The mounting plate 24 has a feed hole 26, into which a paint needle 25 is inserted. A ball valve 27 is installed at the upper end of the feed hole 26, and a side tube 28 is connected to one side of the feed hole 26. A solenoid valve 29 is installed on the side tube 28. A connecting slider 20 is installed inside the mounting column 23. The inlet end of the return pump 30 is connected to the side tube 28. After a coating operation is completed, some paint will remain in the paint needle 25, which may cause dripping. To avoid contaminating the QR code or dripping onto the equipment, the ball valve 27 is closed, and then the solenoid valve 29 is opened. The return pump 30 starts and sucks away the paint remaining in the feed hole 26 and the paint needle 25, thus preventing residual paint dripping. The outlet end of the return pump 30 is connected to a return pipe, which can pump the paint to the paint storage position to avoid paint waste. In the next coating operation, the ball valve 27 needs to be opened and the solenoid valve 29 needs to be closed to inject paint into the feed hole 26 and the paint needle 25 at a uniform speed.

[0037] The display module is a touch screen to facilitate user operation of the recognition system.

[0038] The acquisition device is an ultrasonic sensor. The acquisition device is connected to the information processing module. The palmprint acquisition device acquires the QR code signal and sends the acquired QR code signal to the information processing module. The information processing module processes the QR code signal to obtain the QR code information.

[0039] The receiving unit receives QR code information, the extraction unit extracts pre-registered information from the storage module, and the comparison module matches and compares the obtained QR code information with the information extracted from the storage module.

[0040] In actual use, the printing system and the recognition system work together. The printing system can print a QR code image with a certain thickness, which increases the difficulty of counterfeiting. The recognition system collects QR code information through the acquisition module and identifies the authenticity of the QR code information through the recognition module, making the anti-counterfeiting effect of the QR code more significant.

[0041] When the printing system prints a QR code, printer 2 prints the QR code on the printing paper. The QR code moves below the coating needle 25, and the push rod 6 extends, causing the base plate 7 to descend. The vacuum suction cup 8 holds the printing paper. By controlling the start of the first motor 11, the first lead screw 12 rotates, which causes the side plate 9 to move the guide rod 5, thus positioning the QR code in the center for easy positioning. Then, the support push rod 14 retracts, causing the coating needle 25 and its corresponding structure to descend. The coating needle 25 then applies another layer of coating to the QR code pattern, increasing the thickness of the QR code. During the coating process, the third lead screw 22 is activated, causing it to rotate and move the connecting slider 20 inside the connecting frame 19, thereby controlling the horizontal movement of the coating needle 25. The movement of the second motor 17 drives the second lead screw 18 to rotate, thereby controlling the slider 16 to move on the guide slide 15, which in turn controls the longitudinal movement of the coating needle 25. This allows the thickness of the QR code to be increased according to the set pattern, resulting in higher automation and greater convenience. After one coating operation is completed, some coating may remain in the coating needle 25, which may cause dripping. To avoid contaminating the QR code or dripping onto the equipment, the ball valve 27 is closed, and then the solenoid valve 29 is opened. The return pump 30 is started to suck away the residual coating in the feed hole 26 and the coating needle 25, thus preventing residual coating from dripping. After the QR code thickening is completed, a drying box is also set on the frame 1 to dry the coated QR code, making it more convenient.

[0042] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
