[0001] The utility model relates to the technical field of two-dimensional code printing and detection integrated devices, in particular to a two-dimensional code printing and detection integrated device. Background Art

[0002] In recent years, QR codes have become increasingly recognized and accepted by the public, becoming a new trend in the anti-counterfeiting and traceability market, and their use is growing rapidly. The use of QR codes on product packaging is becoming a growing trend, enabling anti-counterfeiting, promotion, sales promotion, and counterfeiting, truly achieving the "one item, one code" principle.

[0003] For example, the public document with application number 201711376024.7 discloses an integrated device for QR code inkjet printing and code detection, which can simultaneously detect errors in the inkjet-coded paper, promptly detect and dispose of the paper with inkjet coding errors, greatly reducing the error rate of finished products and improving production efficiency. However, the integrated device for printing and detecting QR codes adopts single-sheet conveying and prints one by one during printing. This method requires manual work to regularize the paper in advance so that it can be fed neatly one by one, thereby increasing the amount of manual labor and indirectly reducing work efficiency.

[0004] Therefore, in view of this, the existing structural deficiencies are studied and improved, and an integrated device for printing and detecting a two-dimensional code is proposed. Utility Model Content

[0020] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0021] like Figure 1-Figure 3 As shown, a two-dimensional code printing and detection integrated device includes a workbench 1, a conveyor belt 2 is installed on the inner side of the workbench 1, a feed roller 3 is installed on the left side of the upper surface of the workbench 1, the feed roller 3 is in contact with the upper surface of the conveyor belt 2 and rolls, an inkjet printer 4 is fixedly installed on the upper surface of the workbench 1 to the right of the feed roller 3, a cutting device 5 is provided on the upper surface of the workbench 1 to the right of the inkjet printer 4, and a detection mechanism 6 is installed on the right side of the upper surface of the workbench 1.

[0022] By adopting the above technical solution, the printed paper is wound on the collecting roller, which is mounted on an external bracket, and the printed paper is pulled through under the feeding roller 3 and attached to the surface of the conveyor belt 2 for traction and transportation;

[0023] The feeding roller 3 presses the printing paper to ensure that the printing paper can move closely against the conveyor belt 2;

[0024] The inkjet printer 4 performs inkjet printing on the surface of the printing paper at regular intervals.

[0025] Furthermore, the cutting device 5 includes a support frame 501 fixedly installed on the upper surface of the workbench 1 to the right side of the inkjet printer 4, and springs 502 are fixedly installed on both sides of the lower surface of the support frame 501, and a cutting knife 503 is fixedly installed at the lower end of the spring 502.

[0026] By adopting the above technical solution, the spring 502 provides a pulling force for the cutting blade 503 to move upward.

[0027] Furthermore, the cutting device 5 also includes a movable rod 504 fixedly installed in the middle of the upper surface of the cutting knife 503. The upper end of the movable rod 504 slides through the support frame 501. A tooth groove 505 is opened on the right side of the surface of the movable rod 504.

[0028] By adopting the above technical solution, the cutting knife 503 is limited by the portion where the movable rod 504 passes through, and thus moves more stably.

[0029] Furthermore, the cutting device 5 further includes a half-shaft gear 506 meshingly arranged on the right side of the tooth groove 505 , and a driving motor 507 is installed on the rear side of the half-shaft gear 506 , and the driving motor 507 is fixedly connected to the support frame 501 .

[0030] By adopting the above technical solution, the driving motor 507 drives the half-shaft gear 506 to rotate, thereby engaging the tooth groove 505 to move the movable rod 504 downward, pushing the cutting knife 503 downward for cutting. When the half-shaft gear 506 rotates to the side without the tooth block and is opposite to the tooth groove 505, the meshing force of the half-shaft gear 506 is lost, and the spring 502 will pull the cutting knife 503 upward to move, and so on.

[0031] Furthermore, the detection mechanism 6 includes a fixing frame 601 fixedly installed on the right side of the upper surface of the workbench 1 , and a control comparator 602 is fixedly installed on the upper surface of the fixing frame 601 .

[0032] By adopting the above technical solution, the control comparator 602 is a computer device, which is programmed to input the correct QR code image in advance, so that the correct image is compared with the subsequently input image to determine whether the printing is qualified.

[0033] Furthermore, the detection mechanism 6 also includes a high-speed camera 603 fixedly installed on the lower surface of the fixing frame 601 , and a directional blower 604 fixedly installed on the front right side of the surface of the fixing frame 601 .

[0034] Furthermore, the high-speed camera 603 is connected to the control comparator 602 , and the directional fan 604 is also connected to the control comparator 602 .

[0035] By adopting the above technical solution, the high-speed camera 603 takes a picture of each piece of printed paper and sends it to the control comparator 602 for QR code detection. If the QR code is wrong, the control comparator 602 will start the directional fan 604 to blow off the incorrectly printed paper for sorting.

[0036] Working principle: When using the integrated device for printing and detecting QR codes, first, the entire strip of printed paper is wound on the collecting roller and installed on the external bracket. The printed paper is pulled through the bottom of the feed roller 3 and adhered to the surface of the conveyor belt 2 for traction and transportation. The printed paper enters the inkjet printer 4 for printing. After printing, it moves to the bottom of the support frame 501, and the driving motor 507 drives the half-shaft gear 506 to rotate, thereby engaging the tooth groove 505 to move the movable rod 504 downward, pushing the cutting knife 503 to move downward for cutting. When the half-shaft gear 506 rotates to the side without the tooth block and is opposite to the tooth groove 505, the meshing force of the half-shaft gear 506 is lost at this time, and the spring 502 will pull the cutting knife 503 upward to move, so as to repeat this process to cut the printed paper. The conveying speed of the paper conveying belt 2 remains unchanged, and the inkjet printer 4 also prints at the same time. Therefore, the cutting device 5 can cut the paper at equal distances, thereby ensuring that the cut paper sizes are the same, and ensuring that each piece of printed paper has a QR code. At the same time, this method of printing first and then cutting into segments allows manual loading of materials. When loading, the manual loading of the paper only requires the collection roller on which the paper is wound as a whole to be installed at one time to ensure continuous material transportation. After cutting, the printed paper will be photographed one by one by a high-speed camera 603, and the photos will be sent to the control comparator 602 for QR code detection. If the QR code is wrong, the control comparator 602 will start the directional fan 604 to blow off the wrongly printed printed paper for sorting. This is the working principle of the integrated QR code printing and detection device.
