[0018] The structure of the present invention is further described below with reference to the accompanying drawings.

[0019] Reference Figures 1 to 3 A two-dimensional code recognition and detection device includes a camera 1 for two-dimensional code recognition. The detection device also includes a base 2, a discharge wheel 3, a discharge guide assembly 4, a receiving guide assembly 5, a receiving wheel 6 and a motor 7. The motor shaft is connected to the receiving wheel. A vertical support 11 is provided on the base 1. The camera is located on the side wall of the support and is arranged downward. A workbench 12 is provided below the base 1 corresponding to the two-dimensional code recognition camera. The discharge wheel 3 and the receiving wheel 6 are respectively located on the side walls of the support on both sides of the camera. The discharge guide assembly 4 is located between the discharge wheel and the camera, and the receiving guide assembly 5 is located between the camera and the receiving wheel.

[0020] In this embodiment, the unwinding wheel 3 includes a disc 31, a shaft 32, and a first bearing 33. The disc is fixedly connected to the shaft, which is rotatably connected to the sidewall of the support member via the first bearing. During use, a coil of material with a QR code is placed on the disc. When the motor drives the take-up wheel to rotate, the material pulls the disc to rotate, unloading the material.

[0021] In this embodiment, the discharge guide assembly 4 includes a discharge guide shaft 41 and two first width adjustment members 42 disposed on the discharge guide shaft. The first width adjustment members are movably connected to the discharge guide shaft via a first damping member. The discharge guide shaft is rotatably connected to the side wall of the support member via a second bearing 43. The first width adjustment member is a first disc block, and the first damping member can be a rubber member. The first damping member is located within the inner hole of the first disc block. The first width adjustment member can move along the discharge guide shaft to adjust the distance between the two first width adjustment members. This distance can be adjusted according to barcodes of different widths, accommodating the positioning of two-dimensional codes of different width specifications and preventing the two-digit codes from shifting during transmission.

[0022] In this embodiment, the receiving guide assembly 5 includes a receiving guide shaft 51 and two second width adjustment members 52 disposed on the receiving guide shaft. The second width adjustment members are movably connected to the receiving guide shaft via a second damping member. The receiving guide shaft is rotatably connected to the side wall of the support member via a third bearing 53. The second width adjustment member is a second disc block, and the second damping member can be a rubber member. The second damping member is located within the inner hole of the second disc block. The second width adjustment member can move along the receiving guide shaft to adjust the distance between the two second width adjustment members. This allows the distance between the two second width adjustment members to be adjusted according to barcodes of different widths, is suitable for positioning QR codes of different width specifications, and prevents the QR codes from shifting during transmission.

[0023] In this embodiment, the receiving wheel 6 includes a receiving wheel shaft 61 and two receiving width adjustment members 62. The receiving wheel shaft is rotatably mounted on the side wall of the support member via a fourth bearing 63. The motor main shaft is fixedly connected to the receiving wheel shaft, and the receiving width adjustment member is movably connected to the receiving wheel shaft via a third damping member. The receiving width adjustment member is a third disc block, and the third damping member can be a rubber member. The third damping member is located within the inner hole of the third disc block. The receiving width adjustment member can move along the receiving wheel shaft to adjust the distance between the two receiving width adjustment members. This allows the distance between the two receiving width adjustment members to be adjusted according to barcodes of different widths, and is suitable for positioning QR codes of different width specifications to prevent the two-digit code from being displaced during the receiving process.

[0024] In this embodiment, the detection device also includes a tensioning wheel 8 mounted on the side wall of the support member. The tensioning wheel is fixedly connected to a tensioning wheel shaft 81. The tensioning wheel shaft is rotatably mounted on the side wall of the support member via a fifth bearing 82. The tensioning wheel shaft is connected to an encoder 83. The transmission of the QR code strip drives the tensioning wheel to rotate. The encoder converts the detected rotational angular displacement of the tensioning wheel shaft into an electrical signal and transmits it to the controller. The controller calculates the transmission speed of the QR code based on the received signal. This allows the motor speed to be adjusted according to the transmission speed of the strip.

[0025] In this embodiment, fill lights 9 are provided on the side walls of the support member on both sides corresponding to the camera, and the fill lights are provided corresponding to the workbench below the camera. The fill lights illuminate the QR code on the workbench and provide fill light for the camera to shoot, thereby making the camera's shooting and recognition clearer.

[0026] In this embodiment, the detection device also includes a working status indicator light 10 mounted on the support member. When the QR code is transmitting normally, the working status indicator light is green. When the detected QR code is abnormal, the working status indicator light is red, alerting the operator. In specific implementations, an alarm can also be provided to provide a reminder.

[0027] In this embodiment, the support member 11 is a box structure, the camera is located on the side wall of the box in the longitudinal direction, and a box door 12 is provided on the side wall of the box opposite to the camera, so that the box door can be opened to repair the equipment.

[0028] When the QR code recognition and detection device of the present invention is used, the QR code material tray is placed on the unloading wheel, and then the material belt is guided to the bottom of the camera through the unloading guide assembly, and then guided to the tensioning wheel, and then guided to the receiving wheel through the receiving guide assembly. The motor drives the receiving wheel to rotate, thereby pulling the unloading wheel to unload the material. The encoder converts the detected rotational angular displacement of the tensioning wheel shaft into an electrical signal and transmits it to the controller. The controller calculates the transmission speed of the QR code based on the received signal. In this way, the speed of the motor can be adjusted according to the transmission speed of the material belt. The camera performs visual recognition and detection on the QR code passing under it. When the detected QR code is inconsistent with the preset QR code, the machine stops working and the working status indicator light changes from green to red, thereby rejecting the unqualified QR code. The machine continues to operate, thereby preventing unqualified QR codes from being used in the market and ensuring the consistency and recognizability of the QR code.

[0029] Although the specific embodiments of the present invention are described in detail in conjunction with the accompanying drawings, this should not be construed as limiting the scope of protection of the present invention. Within the scope described by the claims, various modifications and variations that can be made by those skilled in the art without creative work still fall within the scope of protection of the present invention.
