[0042] The code scanning module generally has a light supplement function. In some dim light environment, the pattern of the two-dimensional code may become blurred, making it difficult for the code scanning module to accurately identify. The light supplement lamp can provide additional light to illuminate the two-dimensional code, so that the code scanning module can clearly capture the detailed information of the two-dimensional code, thereby improving the success rate of code scanning. In addition, the light supplement lamp can also facilitate users to quickly identify the position of the code scanning module in a dark environment, so as to facilitate users to use the code scanning function. If the light supplement lamp emits light unevenly, some areas of the two-dimensional code may be too bright, and some areas may be too dark. The overly bright area may cause reflection, making it difficult for the code scanning module to accurately identify the pattern, and the overly dark area may cause the details of the two-dimensional code to be lost, increasing the probability of code scanning failure. Therefore, it is necessary to improve the problem of uneven light emission of the code scanning module.

[0043] The code scanning module of the present application is provided with optical fiber light guide, the optical fiber is arranged along the outer contour of the light shield, the entire optical fiber area will emit light, the optical fiber contacts the light guide cover and guides the light to the light guide cover, finally the area not blocked by the light shield will emit light, so that the code scanning module presents the effect of a whole circle of light, improves the uniformity of light emission of the code scanning module, and further improves the success rate of code scanning.

[0044] As shown in Figures 1 to 3 In one or more embodiments, the present disclosure provides a code scanning module, comprising a light guide cover 100, a light shield 200, an optical fiber 300 and at least one light source 400; the light shield 200 is arranged on one side of the light guide cover 100; the light source 400 is arranged on the side of the light guide cover 100 away from the light shield 200; the optical fiber 300 is arranged on the side of the light guide cover 100 away from the light shield 200, at least one end of the optical fiber 300 is arranged corresponding to the light source 400, and the optical fiber 300 is arranged around the outer periphery of the light shield 200.

[0051] In some embodiments, as shown in Figure 4 The optical fiber 300 comprises a bending portion 310 and a surrounding portion 320. One end of the bending portion 310 is arranged correspondingly to the light source 400, and the other end is connected with one end of the surrounding portion 320. The projection of the surrounding portion 320 on the light guide cover 100 is located in the area outside the projection of the light shield cover 200 on the light guide cover 100. The surrounding portion 320 is arranged around the outer periphery of the light shield cover 200 and extends along the outer contour of the light shield cover 200.

[0052] The surrounding portion 320 is arranged on the light guide cover 100. The surrounding portion 320 is arranged around the outer contour of the light shield cover 200. The bending portion 310 and the surrounding portion 320 are not in the same plane. One end of the bending portion 310 is connected with the surrounding portion 320, and the other end is arranged correspondingly to the light source 400. In this embodiment, the bending portion 310 arranged on the optical fiber 300 can facilitate the correspondence between the optical fiber 300 and the light source 400. The surrounding portion 320 is arranged around one or more circles according to the required light emitting area on the light guide cover 100. The projection of the surrounding portion 320 on the light guide cover 100 does not intersect with the projection of the light shield cover 200 on the light guide cover 100. The light emitted by the surrounding portion 320 is guided to the light guide cover 100 and cannot be blocked by the light shield cover 200, so that the entire circle outside the contour of the light shield cover 200 is illuminated, improving the uniformity of light compensation of the code scanning module.

[0053] Further, as shown in Figure 5As shown, the light guide cover 100 is provided with a mounting groove 110 on the side away from the light shield cover 200, the mounting groove 110 is arranged around the outer periphery of the light shield cover 200 and extends along the outer contour of the light shield cover 200, and the surrounding part 320 is arranged in the mounting groove 110. The mounting groove 110 on the light guide cover 100 is arranged according to the area where light is needed, and the surrounding part 320 is arranged in the mounting groove 110. The mounting groove 110 not only provides a fixed path for the arrangement of the surrounding part 320 to improve the installation accuracy of the optical fiber 300, but also provides a physical barrier for the optical fiber 300 to protect the optical fiber 300 from possible mechanical damage such as being squeezed by heavy objects or being scratched by sharp objects, thereby improving the service life of the optical fiber 300.

[0054] The inner side wall of the mounting groove 110 is provided with a plurality of buckle parts, and the plurality of buckle parts are arranged at intervals along the extension direction of the mounting groove 110; each group of buckle parts includes a first buckle part 120 and a second buckle part 130 arranged opposite to each other, the first buckle part 120 buckles the inner side of the surrounding part 320, and the second buckle part 130 buckles the outer side of the surrounding part 320.

[0055] The first buckle part 120 and the second buckle part 130 can tightly buckle the surrounding part 320 of the optical fiber 300, so that the surrounding part 320 maintains a fixed position in the mounting groove 110, avoiding displacement of the optical fiber 300 due to external force pulling, vibration and other factors, and enhancing the fixing effect of the optical fiber 300; at the same time, the first buckle part 120 and the second buckle part 130 can form a buffer layer between the optical fiber 300 and the inner wall of the mounting groove 110, which can absorb and buffer part of the energy when external impact force acts, reduce the direct impact on the optical fiber 300, and protect the optical fiber 300 from being damaged. Fixing the optical fiber 300 in the mounting groove 110 can also avoid the optical fiber 300 shaking back and forth in the mounting groove 110 and rubbing against the wall of the mounting groove 110, thereby preventing the optical fiber 300 from being abraded, protecting the integrity of the optical fiber 300, and maintaining the optical performance of the optical fiber 300.

[0056] In some embodiments, as Figure 6 As shown, the light guide cover 100 is provided with a recess 140 recessed away from the light shield cover 200, and the light shield cover 200 is arranged in the recess 140; the camera 500 is arranged in the recess 140 and located between the light guide cover 100 and the light shield cover 200.

[0057] The light guide cover 100 is provided with a groove 140, and the light shield cover 200 is arranged in the groove 140 of the light guide cover 100.
