Description

Technical Field

[0001] The utility model relates to the technical field of scanners, in particular to a two-dimensional barcode scanner with intelligent fill light. Background Art

[0002] The two-dimensional barcode scanner with intelligent fill light is a scanning device that uses advanced intelligent fill light technology. It can automatically adjust the fill light brightness and angle in different lighting environments to ensure the accuracy and efficiency of the scanning process. In real life, we often encounter problems such as insufficient light or reflection, which cause the scanning device to be unable to accurately identify the barcode. The two-dimensional barcode scanner with intelligent fill light can effectively solve this problem. It uses the built-in light sensor to monitor the light changes in the scanning environment in real time, and then automatically adjusts the brightness and angle of the fill light based on these data, so that the scanner can obtain the best scanning effect in any lighting environment. In general, the two-dimensional barcode scanner with intelligent fill light is a scanning device with high efficiency, high accuracy and high compatibility. It can quickly and accurately read barcode information in various lighting environments, which brings great convenience to our lives and work.

The handheld barcode scanner gun scanning fill-in light auxiliary device of the utility model can be directly installed on the barcode scanner gun, and does not require additional hand-held, which is convenient for operators to operate and use. 2. The handheld barcode scanner gun scanning fill-in light auxiliary device of the utility model, the angle and distance adjustment device can adjust the distance and angle of the LED fill-in light device from the QR code and the barcode scanner gun scanning port, thereby increasing the success rate of scanning. 3. The handheld barcode scanner gun scanning fill-in light auxiliary device of the utility model uses a flicker-free LED fill-in light device to fill in the light of the use environment, which improves the recognition of the label without causing reflection of the QR code, improves the accuracy of scanning, reduces the possibility of mis-scanning, and improves the efficiency of scanning and warehousing.

[0004] However, when implementing the above technical solution, there are some issues that need to be considered: when the device attempts to scan a barcode on a smooth surface, glare will occur due to light reflection. The presence of this glare will not only reduce the accuracy of the scan, but also have an adverse effect on work efficiency, causing staff to spend more time and energy to ensure the accuracy of the scan when scanning the barcode, thereby reducing overall work efficiency.
