However, in actual production, variables related to hardware, materials, and the environment, such as lighting and the accuracy of transmission and positioning, can cause instability in QR code recognition by laser scanners. This necessitates manual intervention for repeated scanning, impacting production efficiency. Utility Model Content

[0024] The embodiments of this utility model are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain this utility model, and should not be construed as limiting this utility model.

[0025] like Figure 1 As shown, this embodiment provides a QR code recognition device, which includes a fixed frame 1, a scanner assembly 2, and a swing assembly 3. The scanner assembly 2 is rotatably mounted on the fixed frame 1 and has a scanning window 21. The scanning area of ​​the scanning window 21 covers the product QR code and is capable of scanning the product QR code. The swing assembly 3 includes a swing base and a swing member 31. The swing base is mounted on the fixed frame 1, and the swing member 31 is disposed on the swing base. The swing member 31 abuts against the bottom of the scanner assembly 2 and is swingably mounted to drive the scanner assembly 2 to swing back and forth.

[0026] The QR code recognition device of this invention uses a swinging component 31 and the bottom of the scanner assembly 2 to abut against each other. When the scanner assembly 2 scans the product QR code, the swinging component 31 can drive the scanner assembly 2 to swing back and forth, making the scanning window of the scanner assembly 2 a widened dynamic scanning area. Even if there is a slight deviation from the product QR code or the scanning is affected by environmental factors such as light, it can still be covered by the dynamic scanning area, which improves the scanning accuracy and efficiency of the scanner assembly 2. This effectively solves the problem of unstable QR code recognition by laser scanners in actual production processes due to variable factors such as hardware, materials and environment in the prior art.

[0027] In some embodiments, the swing member 31 includes a drive motor 311 and a swing structure 312. The drive motor 311 is mounted on the swing base and is drivenly connected to the swing structure 312. The swing structure 312 abuts against the bottom of the scanner assembly 2, so that the drive motor 311 can drive the swing structure 312 to rotate, thereby the swing structure 312 can drive the scanner assembly 2 to swing back and forth.

[0028] In this embodiment, the swing structure 312 includes, but is not limited to, an eccentric wheel. The eccentric wheel and the bottom of the scanner assembly 2 are abutted together. With this configuration, the drive motor 311 and the eccentric wheel are connected, so that the scanner assembly 2 can be driven to swing back and forth through the eccentric wheel.

[0029] Alternatively, the swing structure 312 can also be a crank-rocker mechanism, where the drive motor 311 drives the crank to rotate, which in turn drives the connecting rod to make the rocker arm drive the scanner assembly 2 to swing back and forth.

[0030] Alternatively, in an embodiment not shown in the figure, the swinging component 31 is a telescopic hydraulic cylinder. The cylinder body of the telescopic hydraulic cylinder is connected to the swinging seat, and the telescopic rod of the telescopic hydraulic cylinder abuts against the bottom of the scanner assembly 2. By the back-and-forth extension and retraction of the telescopic hydraulic cylinder, the scanner assembly 2 is driven to swing back and forth.

[0031] In this embodiment, the scanner assembly 2 includes a scanner body 22 and a connector 23. One end of the connector 23 is connected to the mounting bracket 1, and the other end of the connector 23 is rotatably connected to the scanner body 22. This allows the scanner body 22 to be fixed to the mounting bracket 1 while also allowing it to rotate. The scanner body 22 has a scanning window 21, and a swing member 31 abuts against the bottom of the scanner body 22.

[0032] Furthermore, to enable a rotatable connection between the scanner body 22 and the other end of the connector 23, the scanner assembly 2 also includes a rotating shaft 24, a bearing housing 25, and a bearing body 26. The bearing housing 25 is positioned at the bottom of the scanner body 22, and the bearing body 26 is mounted on the bearing housing 25. One end of the rotating shaft 24 is connected to the other end of the connector 23, and the other end of the rotating shaft 24 passes through the bearing body 26. This configuration allows the scanner body 22 to rotate at the other end of the connector 23.

[0033] In some embodiments, the connector 23 includes a first connecting plate 231 and a second connecting plate 232 that are interconnected. The first connecting plate 231 is connected to the mounting bracket 1, and the second connecting plate 232 is rotatably connected to the scanner body 22. This arrangement facilitates the connection between the mounting bracket 1 and the scanner body 22.

[0034] Furthermore, the first connecting plate 231 and the second connecting plate 232 are perpendicular to each other. This arrangement prevents interference with the mounting bracket 1 when the scanner body 22 reciprocates.

[0035] In this embodiment, the fixing frame 1 includes, but is not limited to, a profile, wherein the profile has the advantages of high strength and lightweight high strength.

[0036] In this embodiment, the fixing frame 1 is made of aluminum. This ensures the structural strength of the fixing frame 1 while also reducing its weight.

[0037] Obviously, the above embodiments of this utility model are merely examples for clearly illustrating the present utility model, and are not intended to limit the implementation of the present utility model. Those skilled in the art can make other variations or modifications based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this utility model should be included within the protection scope of the claims of this utility model.
