Description

Technical Field

[0001] This utility model relates to the field of online monitoring device technology, and in particular to an online monitoring device for QR code printing quality. Background Technology

[0002] As an important component of modern automatic identification technology, QR code printing technology has been widely used in various fields such as product packaging, logistics management, and anti-counterfeiting traceability. The printing quality of QR codes is directly related to the accuracy and efficiency of information recognition. Inferior QR codes may lead to scanning failures, data errors, and other problems, affecting the operation of the entire supply chain. Therefore, it is crucial to realize online monitoring of QR code printing quality during the production process, which can detect defects in a timely manner, reduce scrap rates, and improve product quality consistency.

[0003] Most existing online QR code printing quality monitoring devices are based on vision inspection systems, including a support frame, a conveyor belt, and a fixedly installed recognition and scanning inspection device. The conveyor belt is used to continuously transport the object to be inspected, while the scanning inspection device acquires and analyzes images of the QR codes on the object's surface. However, the height of the scanning inspection device is usually fixed and cannot be adjusted according to the size of the object. In practical applications, the size of the objects to be inspected varies greatly, from small electronic components to large packaging boxes. A fixed-height scanner may lead to a mismatch in scanning distance: for smaller objects, a scanning distance that is too far will reduce image resolution and affect detail recognition; for larger objects, a scanning distance that is too close may cause image distortion or partial areas that cannot be covered. Therefore, improvements are needed. Utility Model Content

[0024] Reference Figures 1 to 5 The present invention provides a further description of an embodiment of an online monitoring device for QR code printing quality.

[0025] An online monitoring device for QR code printing quality includes a support frame 1 and a conveyor belt 2, the conveyor belt 2 being disposed within the support frame 1 for transporting the object to be detected; it also includes: a support frame 3, disposed on the support frame 1 and fixedly connected to the support frame 1; a support groove 4, formed on the support frame 3; a support block 5, disposed within the support groove 4 and slidably connected to the support groove 4; a support plate 6, fixedly connected to the support block 5; a recognition scanning detector 7, disposed on the support plate 6 and fixedly connected to the support plate 6; a lifting mechanism, disposed on the support frame 3 for adjusting the height of the recognition scanning detector 7; and a fixing mechanism, disposed on the support frame 1 for fixing the object to be detected.

[0026] Reference Figure 1 and Figure 4 In a preferred embodiment, the lifting mechanism includes: a lifting frame 8, which is mounted on a support frame 3 and fixedly connected to the support frame 3; a lifting motor 9, which is fixedly connected to the lifting frame 8; a lifting shaft 10, which is fixedly connected to the output end of the lifting motor 9 and rotatably connected to the support frame 3; a sliding groove 11, which is formed on the support frame 3; two sliding blocks 12, which are symmetrically arranged in the sliding groove 11, slidably connected to the sliding groove 11, and threadedly connected to the lifting shaft 10; and a rotating component, which is mounted on the sliding blocks 12.

[0027] When in operation, the lifting motor 9 is started, which drives the lifting shaft 10, which is fixedly connected to the output end of the lifting motor 9, to rotate on the support frame 3, so that the sliding block 12 driven by the lifting shaft 10 slides in the sliding groove 11.

[0028] Reference Figure 4 In a preferred embodiment, the rotating component includes: a first rotating shaft 13, which is disposed on the sliding block 12 and fixedly connected to the sliding block 12; a rotating plate 14, which is fixedly connected to the first rotating shaft 13; a second rotating shaft 15, which is disposed on the rotating plate 14 and rotatably connected to the rotating plate 14; and a rotating frame 16, which is disposed on the second rotating shaft 15, fixedly connected to the second rotating shaft 15, and fixedly connected to the support plate 6.

[0029] During operation, the rotating plate 14, which is rotatably connected to the first rotating shaft 13, rotates, causing the rotating frame 16, which is fixedly connected to the second rotating shaft 15, to move, so that the support plate 6, which is fixedly connected to the rotating frame 16, drives the support block 5 to slide in the support groove 4.

[0030] Reference Figure 5In a preferred embodiment, the fixing mechanism includes: a fixing cylinder 17, which is disposed on the support frame 1 and fixedly connected to the support frame 1; a fixing block 18, which is disposed on the conveyor belt 2, slidably connected to the conveyor belt 2, and fixedly connected to the output end of the fixing cylinder 17; a connecting block 19, which is disposed inside the support frame 1 and fixedly connected to the support frame 1; a connecting groove 20, which is formed inside the connecting block 19; multiple elastic springs 21, which are evenly disposed inside the connecting groove 20 and fixedly connected to the connecting block 19; and an elastic block 22, which is disposed inside the connecting groove 20, slidably connected to the connecting groove 20, and fixedly connected to the elastic springs 21.

[0031] During operation, the fixed cylinder 17 is activated, which drives the fixed block 18, which is fixedly connected to the output end of the fixed cylinder 17, to slide on the conveyor belt 2. This causes the fixed block 18 to move the detection object closer to the connecting block 19. When the detection object comes into contact with the elastic block 22, the elastic block 22 slides into the connecting groove 20 on the connecting block 19, causing the elastic spring 21, which is fixedly connected to the elastic block 22, to be compressed, generating elastic potential energy.

[0032] Working principle: In use, the object to be detected is first placed on the conveyor belt 2 for transmission. When the object is directly below the recognition scanning detector 7, the fixing cylinder 17 is activated, which drives the fixing block 18, which is fixedly connected to the output end of the fixing cylinder 17, to slide on the conveyor belt 2. This causes the fixing block 18 to move the object closer to the connecting block 19. When the object contacts the elastic block 22, the elastic block 22 slides into the connecting groove 20 on the connecting block 19, which compresses the elastic spring 21, which is fixedly connected to the elastic block 22, generating elastic potential energy until the object contacts the fixing block 18 and the connecting block 19, thereby fixing the object and preventing shaking or displacement that would affect the detection results.

[0033] Then, when the height of the identification scanning detector 7 needs to be adjusted, the lifting motor 9 is started, which drives the lifting shaft 10, which is fixedly connected to the output end of the lifting motor 9, to rotate on the support frame 3. This causes the lifting shaft 10 to rotate and drive the sliding block 12 to slide in the sliding groove 11, causing the rotating plate 14, which is rotatably connected to the first rotating shaft 13, to rotate. This causes the rotating frame 16, which is fixedly connected to the second rotating shaft 15, to move, causing the support plate 6, which is fixedly connected to the rotating frame 16, to drive the support block 5 to slide in the support groove 4. This causes the identification scanning detector 7, which is fixedly connected to the support plate 6, to rise and fall, thereby adjusting the height of the identification scanning detector 7 and making the scanning of the detected object more accurate.

[0034] The above description of the embodiments enables those skilled in the art to make or use the present invention. Various modifications to these embodiments will be readily apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention. Therefore, the present invention is not to be limited to the embodiments shown herein, but is to be accorded the widest scope consistent with the principles and novel features disclosed herein.
