A processing module is provided below the handheld part, and a storage module is provided above the processing module. The scanning button and the vacuuming button are connected to the processing module through a communication module. The base is provided with a battery assembly and a charging assembly for charging the battery assembly.

[0004] While the above-mentioned technical solutions have their respective advantages, most barcode scanners still have some shortcomings in use. For example, in actual use, ambient lighting conditions are complex and changeable. When the light is too dim, the barcode image is blurry, leading to decoding failure. When the light is too strong, reflections are likely to occur, which will also affect the scanning accuracy and efficiency.

[0005] Currently, existing barcode scanner fill light lenses have some shortcomings. Most fill light lenses use a fixed brightness light source and cannot adaptively adjust according to the ambient light intensity. In scenarios with large changes in lighting, frequent manual adjustments to the fill light mode are required, which is cumbersome and affects work efficiency. Therefore, we propose a light-adaptive fill light lens for barcode scanners. Utility Model Content

[0006] The purpose of this invention is to provide an adaptive light-adaptive lens for barcode scanners to address the deficiencies mentioned in the background art.

[0007] To achieve the above objectives, this utility model provides the following technical solution: The barcode scanner's adaptive light-adaptive fill light lens includes a lens housing. A ring-shaped lampshade is located at the center of the lens housing. A ring-shaped fill light cavity is located on the front side of the ring-shaped lampshade, containing multiple fill light LEDs. A barcode scanner lens base is located at the center of the ring-shaped lampshade. A barcode scanner lens is fixedly mounted at the center of the front side of the barcode scanner lens base. Two symmetrical light sensors are located inside the lens housing. A control mainboard is also located inside the lens housing. A front transparent protective cover is fixedly mounted on the front side of the lens housing.

[0008] Preferably, the scanning lens is located near the front part of the lens housing, and the light sensor is parallel to the optical axis of the scanning lens; This setting helps the light sensor detect the intensity of ambient light.

[0009] Preferably, an inner fixing frame is fixedly installed on the inner wall of the lens housing, and a fixing bracket is fixedly installed on the annular lampshade and the scanning lens base. The fixing bracket is detachably installed on the front side of the inner fixing frame. This feature facilitates the secure installation of the lens housing and the ring lamp cover.

[0010] Preferably, a reflective coating is provided on the inner surface of the annular supplementary lighting cavity, and the plurality of supplementary lighting beads are evenly distributed in a ring. The reflective coating in this feature can focus light onto the scanning area, improving lighting efficiency and reducing light waste. At the same time, multiple LED beads can enhance the illumination effect.

[0013] Preferably, a sensor base is fixedly mounted on the light sensor, and the sensor base is fixedly mounted on the inner wall of the lens housing.

[0014] Preferably, a smooth and easy-to-clean layer is provided on the front side of the front transparent protective cover, and the smooth and easy-to-clean layer and the front transparent protective cover are integrally formed. This feature makes the surface of the front transparent protective cover easier to clean. Compared with the prior art, the beneficial effects of this utility model are: 1. This utility model sets two light sensors, one on the left and one on the right, parallel to the optical axis of the scanning lens, inside the lens housing. These sensors are electrically connected to the control motherboard and multiple LED beads in the ring-shaped fill light cavity. This enables the light sensors to detect the ambient light intensity in real time, and the control motherboard to automatically adjust the brightness of the fill light beads based on the detection data. This eliminates the need for frequent manual adjustment of the fill light mode, solves the problem of the inconvenience of using a fixed brightness light source in scenes with changing lighting, and improves the efficiency of scanning.

[0015] 2. This utility model provides a reflective coating on the inner surface of the annular supplementary lighting cavity, with multiple supplementary lighting beads evenly distributed in a ring. This allows the light to be focused onto the scanning area through the reflective coating, improving the uniformity and efficiency of supplementary lighting and reducing light waste. At the same time, the cooperation between the annular lamp cover and the scanning lens base ensures that the supplementary lighting range matches the shooting range of the scanning lens, solving the problems of fixed and uneven supplementary lighting range and achieving the effect of improving scanning accuracy.

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model. Please see Figures 1-4 This utility model provides a technical solution: an adaptive light-adaptive supplementary light lens for a barcode scanner, including a lens housing 1. The rear side of the lens housing 1 is connected to the outside and is sealed by a detachable rear cover. An annular lampshade 12 is provided at the center of the interior of the lens housing 1. An annular supplementary light cavity 121 is provided on the front side of the annular lampshade 12. Multiple supplementary light beads 131 are provided inside the annular supplementary light cavity 121. A barcode scanner lens base 15 is provided at the center of the annular lampshade 12. A barcode scanner lens 151 is fixedly installed at the center of the front side of the barcode scanner lens base 15. The lens housing 1 has two opposing left and right sides. The light sensor 16 is located in the lens housing 1, and a control motherboard 17 is also provided inside the lens housing 1. The barcode scanning lens 151 is located near the front of the lens housing 1. The light sensor 16 is parallel to the optical axis of the barcode scanning lens 151. By setting the barcode scanning lens 151 near the front of the lens housing 1 and making the light sensor 16 parallel to the optical axis of the barcode scanning lens 151, the light sensor 16 can accurately capture the ambient light of the scanning area. In conjunction with the control motherboard 17 to regulate the supplementary light bead 131, the supplementary light brightness can be automatically adjusted according to the ambient light, thus solving the problem of poor barcode scanning effect in scenes with variable lighting when the supplementary light is fixed.

[0019] In this embodiment, an inner fixing frame 10 is fixedly installed on the inner wall of the lens housing 1, and a fixing bracket 11 is fixedly installed on the ring lamp cover 12 and the barcode scanning lens base 15. The fixing bracket 11 is detachably installed on the front side of the inner fixing frame 10, so that each component is installed firmly and is easy to disassemble and maintain, reducing the difficulty of assembly and maintenance, ensuring the stability of the device structure, and extending the service life.

[0020] like Figure 3 As shown, a reflective coating 122 is provided on the inner surface of the annular fill light cavity 121, and multiple fill light beads 131 are evenly distributed in a ring. The reflective coating 122 concentrates the light to the scanning area, enhances the concentration and uniformity of the fill light, reduces light waste, improves the fill light efficiency, and avoids the problem of blurry scanning caused by uneven light.

[0021] like Figure 4As shown, an inner through hole 123 is provided on the rear side wall of the annular supplementary lighting cavity 121. A lamp holder 13 is fixedly installed on multiple supplementary lighting beads 131. The lamp holder 13 is detachably installed on the rear side of the annular lamp cover 12. The supplementary lighting beads 131 are inserted and matched with the inner through hole 123, which makes it easy to replace supplementary lighting beads 131 of different specifications according to usage requirements, thereby improving the adaptability and flexibility of the device.

[0022] like Figure 1 As shown, an inner limiting sleeve 14 is fixedly installed on the inner annular side of the ring lamp cover 12. The scanning lens base 15 is located inside the inner limiting sleeve 14 and is inserted and matched with the inner limiting sleeve 14 to ensure that the scanning lens 151 and the ring supplementary light cavity 121 are concentric, so that the supplementary light range is precisely matched with the scanning area, and avoids the supplementary light and scanning effect being affected by positional deviation.

[0023] like Figure 1 As shown, a sensor base 161 is fixedly installed on the light sensor 16. The sensor base 161 is fixedly installed on the inner wall of the lens housing 1, so that the light sensor 16 is installed firmly, the detection angle is stable, and the accuracy of the ambient light detection data is guaranteed, providing a reliable basis for supplementary lighting adjustment.

[0024] like Figure 2 As shown, a front transparent protective cover 2 is fixedly installed on the front side of the lens housing 1. A smooth and easy-to-clean layer 20 is provided on the front side of the front transparent protective cover 2. The smooth and easy-to-clean layer 20 and the front transparent protective cover 2 are integrally formed to reduce dust and dirt adhesion, facilitate cleaning, ensure that the light transmittance is not affected, and guarantee the supplementary lighting effect and the imaging clarity of the barcode scanning lens 151.

[0025] It is worth noting that the control motherboard 17 is electrically connected to the light sensor 16 and the fill light bead 131. The fill light bead 131 can be an RGB three-color bead. The light color and brightness can be adjusted by the control motherboard 17 to adapt to the scanning requirements of different colored barcodes and avoid the problem of insufficient contrast between the barcode and the background when using monochromatic light for fill light. When the light sensor 16 detects insufficient light brightness, the control motherboard 17 controls the fill light bead 131 to work and perform fill light operation.

[0026] Finally, it should be noted that the control motherboard 17, light sensor 16, supplementary light bulb 131, corresponding control system, and external power supply involved in this utility model are all general standard parts or parts known to those skilled in the art. Their structure and principle can be known to those skilled in the art through technical manuals or conventional experimental methods. In the idle space of this device, all the above-mentioned electrical components, which refer to power elements, electrical components, and the matching controller and power supply, are connected by wires. The specific connection method should refer to the working principle of this utility model. The electrical connections between each electrical component are completed in the order of operation. The detailed connection methods are all technologies known in the art. When the light adaptive supplementary light lens of the barcode scanner of this utility model is in use, the barcode scanning lens 151 on the front side of the lens housing 1 is aligned with the barcode, and the two light sensors 16 on the left and right sides are stably detected by the sensor base 161. Because they are parallel to the optical axis of the barcode scanning lens 151, they can accurately capture the light in the scanning area. The data is transmitted to the control motherboard 17. If the light is insufficient, the control motherboard 17 activates the supplementary light lamp 131 in the annular supplementary light cavity 121. The supplementary light bulb 131 is installed on the rear side of the ring lamp cover 12 via the lamp holder 13. When the light is emitted, the reflective coating 122 focuses the light and evenly illuminates the barcode. After use, the smooth and easy-to-clean surface of the front transparent protective cover 20 makes it easy to clean.
