[0002] Barcode scanning and identification devices are widely used in many fields and industries, such as retail, manufacturing, logistics, healthcare, warehousing, and even security. They can quickly and accurately identify information. Barcode scanning and identification devices can come in various sizes, scanning methods, reading resolutions, scanning distances, scanning areas, reading depths, installation methods, and interface types. They can also be configured into barcode scanning networks to work in groups.

[0003] Existing barcode scanning and recognition devices suffer from slow recognition speed and low accuracy in low-light environments due to insufficient light contrast, which seriously affects work efficiency. Although some devices have attempted to add supplementary lighting components, the supplementary lighting angle is fixed, it is inconvenient to install and remove, and the supplementary lighting intensity cannot be adapted to different lighting environments, resulting in poor applicability.

The mains plug 6 has a wire length of 1.5-2m and a rated current of 1A.

[0025] Reference Figure 1-5As shown in this embodiment: the surface of the scanner 1 is provided with a supplementary lighting device 2. The supplementary lighting device 2 includes two fixed plates 201 fixedly installed on the surface of the scanner 1. A rotating shaft 202 is rotatably connected between the two fixed plates 201. A rotating support plate 203 is fixedly installed on the outer wall surface of the rotating shaft 202. A mounting base 204 is fixedly installed on the surface of the rotating support plate 203. An LED light panel 205 is movably installed inside the mounting base 204. A rechargeable lithium battery is provided inside the LED light panel 205. A rotating support plate 203 is fixedly installed on the outer wall surface of the rotating shaft 202. The limiting roller 206 has multiple limiting holes 207 distributed in a ring on its outer wall surface. A through groove 208 is formed on the surface of a fixed plate 201. A vertical rod 209 is fixedly installed between the inner walls of the upper and lower ends of the through groove 208. A slide plate 210 is slidably connected to the outer wall surface of the vertical rod 209. A limiting rod 211 is fixedly installed on the surface of the slide plate 210. The end of the limiting rod 211 away from the slide plate 210 is located inside the limiting hole 207. A spring 212 is fixedly installed on the bottom surface of the slide plate 210. One end of the sliding plate 210 is fixedly connected to the bottom surface of the through groove 208. Two vertical grooves 213 are formed on the surface of one of the fixed plates 201, and a U-shaped plate 214 is slidably connected between the two vertical grooves 213. The rotating shaft 202 is made of 45# steel with a rotation damping coefficient of 0.5 N·m. The rotating bearing plate 203 is made of aluminum alloy, and the mounting base 204 is made of ABS material. It has an internal groove that matches the LED light panel 205. The LED light panel 205 has a power of 5W, a beam angle of 120°, a color temperature of 5500K, and a surface adhesive... The LED light panel 205 is covered with an anti-glare film and has a 2000mAh lithium battery with a voltage of 3.7V inside. It supports Micro-USB charging. The edge of the LED light panel 205 has an independent push-button switch connected in series with the lithium battery via a wire. The spring 212 is made of 65Mn material with a wire diameter of 1mm, an outer diameter of 8mm, a free length of 3cm, an elastic coefficient of 5N / cm, and an elastic force of 7.5N when the compression stroke is 1.5cm. There are 6 limiting holes 207 with a spacing of 60° between adjacent holes, which can be adjusted from 0-360°.

[0026] Reference Figure 3-6 As shown in this embodiment: both sides of the LED light board 205 are provided with fixing devices 3. The fixing devices 3 include extension plates 31 fixedly installed on both sides of the LED light board 205. The surfaces of the two extension plates 31 are threaded with bolts 32. Both sides of the mounting base 204 are fixedly installed with positioning plates 33. The surfaces of the two positioning plates 33 are provided with threaded holes 34 that match the bolts 32.

[0027] Working principle: When using this device, first check if the handle 4 of the scanner 1 is intact, if the scanning window 5 is clean, and if the power plug 6 wire is damaged. Ensure that all components of the device are functioning properly. Then, plug the power plug 6 into a power outlet to power on the scanner 1. Hold the handle 4 and use the operation buttons on the surface to turn on the device and set the parameters. After setting, align the scanning window 5 with the barcode on the item to scan. The scanned information will be displayed on the screen in real time. When the light is insufficient, activate the supplementary lighting function. First, turn on the LED light panel 205. Place the LED light board into the mounting base 204, aligning the extension plates 31 on both sides with the positioning plate 33, and aligning the bolts 32 with the threaded holes 34. Then, tighten the bolts to fix the LED light board onto the mounting base to prevent the light board from shaking during supplementary lighting. If it is necessary to adjust the supplementary lighting angle, first slide the U-shaped plate 214 to move it down along the vertical groove 213. The U-shaped plate 214 drives the slide bar 210 to slide down along the vertical rod 209 and compress the spring 212. While the spring 212 is compressed, the limiting rod 211 on the surface of the slide bar 210 disengages from the limiting hole 207 of the limiting roller 206, releasing the limit. When the rotating shaft 202 is in position, rotate the bearing plate 203. This rotates the mounting base 204 and the LED light panel 205 synchronously, adjusting the LED light panel 205 to provide optimal illumination for the barcode. After adjustment, release the U-shaped plate 214. The return force of the spring 212 pushes the slide plate 210 upward, causing the limit rod 211 to re-insert into the corresponding limit hole 207, locking the rotating shaft 202 again to prevent angle deviation. Finally, press the independent switch on the edge of the LED light panel 205 to utilize the internal rechargeable... Powered by a lithium battery, the LED light panel 205 emits light that enhances the brightness of the barcode area, solving the problems of slow scanning speed and low accuracy caused by insufficient light, ensuring efficient scanning. After use, turn off the LED light panel 205 switch. If the lithium battery is low on power, it can be charged via the Micro-USB interface. Then, turn off the scanner 1 power and unplug the AC power plug 6 to complete the entire operation process. Through the above steps, the device can work stably in different lighting environments, effectively improving the efficiency and accuracy of barcode scanning.
