[0041] like Figure 1 and Figure 2 As shown, this embodiment provides a barcode scanning gun, which includes a shell component 1, a camera component 2, a main board 9 and a fill light component 3.

[0042] Specifically, the housing assembly 1 is provided with a code scanning part 11; the camera assembly 2 is provided at the code scanning end of the code scanning part 11, and the camera assembly 2 is used for code scanning; the fill light assembly 3 is provided at the code scanning end of the code scanning part 11, and the fill light assembly 3 includes a plurality of fill light sources, and the plurality of fill light sources are located in the circumference of the camera assembly 2, and the fill light sources are used for fill light when the camera assembly 2 scans the code; the main board 9 is provided in the housing assembly 1, and the camera assembly 2 and the fill light source are electrically connected to the main board 9. When working, the main board 9 controls the camera assembly 2 and the fill light source to work, and selects different types of fill light sources for fill light according to the scene requirements to meet the application of various scenes, and the fill light source assists the camera assembly 2 to scan the code, thereby improving the success rate of code scanning.

[0043] In this embodiment, the types of fill light sources include diffuse light sources 31, direct light sources 32, and polarized light sources 33. When encountering a highly reflective metal product, the barcode scanner switches to the polarized light source 33, and the polarized light source 33 emits polarized light for fill light; when encountering a product with a relatively rough surface, the barcode scanner switches to the direct light source 32, and the direct light source 32 emits direct light for fill light; when encountering a cylindrical product, the barcode scanner switches to the diffuse light source 31, and the diffuse light source 31 emits diffuse light for fill light, thereby increasing the success rate of scanning. Preferably, the color of the diffuse light source 31 can be red, the color of the direct light source 32 can be blue, and the color of the polarized light source 33 can be white. The colors of the diffuse light source 31, the direct light source 32, and the polarized light source 33 are different, which is convenient for operators to understand the type of light source currently used.

[0044] Specifically, Figure 2 and Figure 3 As shown, the fill light assembly 3 includes a diffusion lampshade 34 and a first light board 35. The first light board 35 is electrically connected to the main board 9. The first light board 35 is provided with a first avoidance hole 352. The code scanning end is provided with a mounting port 111. The diffusion lampshade 34 is installed in the mounting port 111. The diffusion lampshade 34 is provided with a transparent diffusion light groove 341. The bottom of the diffusion light groove 341 is provided with a second avoidance hole 342. The cross-sectional area of ​​the diffusion light groove 341 gradually decreases toward the direction approaching the first light board 35. The camera assembly 2 is penetrated by the first avoidance hole 352 and the second avoidance hole 342. The first light board 35 is provided with a plurality of first light sources 351. The plurality of first light sources 351 are arranged around the first avoidance hole 352. The first light source 351 can emit diffused light through the side wall of the diffusion light groove 341. Among them, when it is necessary to switch to the diffuse light source 31, the main board 9 controls the first light source 351 of the first lamp board 35 to work. Since the side wall of the diffuse light groove 341 is inclined relative to the light beam of the first light source 351, the light beam emitted by the first light source 351 emits diffuse light through the side wall of the diffuse light groove 341, and the diffuse light source 31 is formed by the first light source 351 and the diffuse lamp cover 34.

[0045] Preferably, one of the inner wall of the mounting opening 111 and the outer wall of the diffusion lamp cover 34 is provided with a snap-in groove 112, and the other is provided with a snap-in wall 343, and the snap-in wall 343 can be snap-into the snap-in groove 112, thereby realizing the installation of the diffusion lamp cover 34 on the scanning end of the barcode scanning gun.

[0046] In this embodiment, the housing assembly 1 includes a top cover 13 and a shell 14. When the top cover 13 is connected to the shell 14, a mounting opening 111 is formed. A snap-fitting groove 112 is provided in the mounting opening 111, and a snap-fitting wall 343 is provided on the outer wall of the diffusion lampshade 34. The top cover 13 and the shell 14 can be connected by screws or snap-fitting to form a code scanning part 11. During assembly, a part of the snap-fitting wall 343 can be snap-fitted into a part of the snap-fitting groove 112 on the shell 14, and then the top cover 13 is installed, and another part of the snap-fitting wall 343 is snap-fitted into a part of the snap-fitting groove 112 on the top cover 13, so that the diffusion lampshade 34 is fixed in the mounting opening 111.

Among them, one end of the reflector 36 can be connected to the diffusion lampshade 34 by screws, and the light beam of the first light source 351 is entirely located in the diffusion cavity, and diffused light is emitted through the side wall of the diffusion light groove 341, thereby increasing the intensity of the fill light and reducing energy consumption.

[0048] It should be noted that the present embodiment also provides the working principle of the diffuse light source 31. Shading powder is added to the side wall of the diffuse light groove 341. When the first light source 351 emits a light beam, part of the light beam is directly discharged through the side wall of the diffuse light groove 341. Part of the light beam is reflected into the diffuse cavity by the shading powder. The inner wall of the shading powder reflector 36 in the diffuse light groove 341 and the reflection of the first light board 35 form diffuse reflection. Finally, diffuse light is generated through the side wall of the diffuse light groove 341, thereby improving the uniformity of the diffuse light.

The shading bracket 22 is provided with a first avoidance hole 352 and a second avoidance hole 342. The inner wall shape of the second avoidance hole 342 matches the outer wall shape of the shading bracket 22. Among them, the lens board 21 is used to take pictures to the CPU on the main board 9, and the CPU performs code reading processing. The lens board 21 is connected to the main board 9 through a flexible printed circuit (FPC). When working, the main board 9 controls the camera 211 on the lens board 21 to scan the code. Since the camera 211 is located in the light shielding hole 221 of the light shielding bracket 22, the side wall of the camera 211 will not be affected by the first light source 351, which is conducive to imaging; furthermore, the inner wall shape of the second avoidance hole 342 matches the outer wall shape of the light shielding bracket 22, and the inner wall of the second avoidance hole 342 fits the outer wall of the light shielding bracket 22, which will not cause light leakage from the first light source 351.
