[0002] Barcode readers are mainly used for product tracking and tracing, collecting data by automatically identifying carriers such as 1D / 2D codes and RFID tags.

[0003] Existing barcode readers directly identify 1D / 2D barcodes or RFID tags in indoor lighting conditions. However, poor indoor lighting makes it difficult for barcode readers to accurately identify the codes to be read. In addition, some barcode readers have light-emitting devices on the side to illuminate the codes to be read on the product. However, the light-emitting devices and barcode readers are separated and not connected. This can easily lead to inaccurate relative positions between the barcode readers and the light-emitting devices, which will affect the actual reading accuracy.

[0004] Therefore, it is necessary to design a barcode reading device and production line that can effectively improve barcode reading accuracy.

[0047] In view of the aforementioned deficiencies in existing barcode reading devices, the applicant, based on years of extensive practical experience and professional knowledge in the design and manufacture of such products, and in conjunction with theoretical application, actively conducted research and innovation in order to create a solution to the deficiencies in the existing technology and make the barcode reading device more practical. After continuous research, design, and repeated prototype production and improvement, this utility model with real practical value was finally created.

[0048] Please refer to Figures 1 to 5 This utility model provides a code reading device, including a code reader 1, a connecting frame 2, and a spherical integrating light source 3.

[0049] The two ends of the connecting bracket 2 are bent and fixedly connected to the ends of the spherical integrating light source 3 away from the code reader 1; the end of the spherical integrating light source 3 near the code reader 1 is provided with a detection through hole 301, and the code reader 1 is used to read the code to be read on the workpiece illuminated by the spherical integrating light source 3 through the detection through hole 301.

[0050] In this embodiment, the barcode reader 1 and the spherical integrating light source 3 are fixedly connected via a connecting bracket 2. This ensures the relative position between the spherical integrating light source 3 and the barcode reader 1, allowing the spherical integrating light source 3 to accurately illuminate the appropriate position on the workpiece under test. The spherical integrating light source 3 can better illuminate the barcode to be read on the workpiece, which can be a 1D / 2D barcode, RFID tag, etc. The barcode reader 1 can accurately detect the barcode to be read on the workpiece under test through the detection through-hole 301 on the spherical integrating light source 3, significantly improving the barcode reading accuracy of the barcode reader 1.

[0051] It should also be noted that the two ends of the connecting frame 2 are bent and fixedly connected to the ends of the sphere integrating light source 3 that are away from the code reader 1, and the connecting frame 2 will not block the light emitted by the sphere integrating light source 3.

[0052] Optionally, the connecting frame 2 includes a C-shaped support 21 and a connecting plate 22;

[0053] The C-shaped support 21 spans the spherical integrating light source 3, and the connecting plate 22 is fixedly connected to the C-shaped support 21 to support the barcode reader 1. The C-shaped support 21 spans the spherical integrating light source 3 and its two ends are respectively connected to the bottom of the spherical integrating light source 3, making the connection structure more stable and reliable. The connecting plate 22 is installed on the C-shaped support 21 and can stably support the barcode reader 1, ensuring the installation reliability of the barcode reader 1.

[0054] Optionally, a control circuit board 4 is installed between the connecting plate 22 and the C-shaped support 21, and the control circuit board 4 is provided with a clearance hole 41 coaxial with the detection through hole 301; a transparent dustproof plate 5 is installed on the side of the control circuit board 4 near the C-shaped support 21, and the transparent dustproof plate 5 is used to seal the detection through hole 301. The control circuit board 4 is installed between the connecting plate 22 and the C-shaped support 21, which shortens the connection path between the control circuit board 4 and the barcode reader 1, and also shortens the connection path between the control circuit board 4 and the spherical integrating light source 3, effectively simplifying the connection path. In addition, the transparent dustproof plate 5 can effectively prevent dust from entering the control circuit board 4 along the detection through hole 301. The clearance hole 41 coaxial with the detection through hole 301 allows the control circuit board 4 to be installed in a more suitable position without affecting the normal operation of the barcode reader 1.

[0055] Optionally, the C-shaped support 21 is provided with a positioning groove 2101 for positioning the transparent dustproof plate 5 so that the transparent dustproof plate 5 can be accurately installed in the appropriate position.

[0056] Optionally, the code reader also includes a connecting cable strip 6; the C-shaped support 21 is provided with a circuit through hole 2012, the spherical integrating light source 3 is provided with a connecting plug, the connecting cable strip 6 passes through the circuit through hole 2012 and its two ends are respectively connected to the connecting plug and the code reader 1; the connecting plug is located on the side of the C-shaped support 21. In this embodiment, the connecting cable strip 6 passes through the circuit through hole 2012, thereby realizing the connection between the control circuit board 4 and the spherical integrating light source 3. The length of the connecting cable strip 6 can be set to be shorter, and there is no need to bend the connecting cable strip 6. In addition, the connecting plug is located on the side of the C-shaped support 21, which can make the C-shaped support 21 play a certain role in shielding the connecting plug, that is, the side of the C-shaped support 21 can play a certain role in protecting the connecting plug.

[0057] Optionally, the spherical integrating light source 3 includes an integrating hemispherical shell 31 and a support ring 32; the two opposite ends of the connecting frame 2 are connected to the support ring 32, and the integrating hemispherical shell 31 is provided with a detection through hole 301.

[0058] Optionally, the support ring 32 is also equipped with an annular light-emitting component 33 for emitting light onto the inner wall surface of the integrating hemisphere shell 31; the annular light-emitting component 33 is installed on the side of the support ring 32 near the integrating hemisphere shell 31. The light emitted by the annular light-emitting component 33 is reflected by the integrating hemisphere shell 31 and projected onto the workpiece under test from various directions, thereby illuminating the code to be read on the surface of the workpiece, enabling the code reader 1 to read the code under good lighting conditions and improving the accuracy of code reading.

[0059] In another specific embodiment, the connecting frame 2 has locking and positioning holes 2001 at both ends; the spherical integrating light source 3 has locking and positioning protrusions corresponding to the locking and positioning holes 2001. Specifically, the locking and positioning holes 2001 and the locking and positioning protrusions are locked together, thereby achieving positioning between the connecting frame 2 and the spherical integrating light source 3 and simplifying the installation steps. Of course, connecting screws can also be used to achieve a fixed connection between the ends of the connecting frame 2 and the spherical integrating light source 3.

[0060] Optionally, the connecting bracket 2 has mounting parts at opposite ends for attaching the spherical integrating light source 3.
