Light-supplementing fixed code sweeper

Abstract

The invention provides a light-supplementing fixed code sweeper, which comprises a shell, a transparent cover plate, a circuit board, a code scanning module, a plurality of light emitting units and aplurality of optical diffusion plates, wherein the bottom edge, the side edge and the mask of the shell form a containing space, and the mask is concaved in the containing space and a groove is formedabove the mask. The side part of the mask is provided with a plurality of first holes and the bottom of the mask is provided with a second hole; the transparent cover plated is fixedly arranged on the shell and can seal the groove. The code scanning module integrated on the circuit board is provided with a camera correspondingly arranged in the second hole, wherein the camera faces the transparent cover plate and its optical axis direction is perpendicular to the transparent cover plate; the light emitted by the plurality of light emitting units respectively arranged in the plurality of firsthole is emitted to the groove through a plurality of optical invention plates. The light-supplementing fixed code sweeper reduces reflections or flare by low-angle illumination of target area, thereby the production efficiency of the product is higher.

Description

technical field [0001] The invention relates to the field of barcode scanning equipment, in particular to a supplementary light type fixed code scanner. Background technique [0002] A code scanner is a reading device used to scan the information contained in a barcode. Using optical principles, it decodes the content of a one-dimensional or two-dimensional barcode and transmits it to a computer or other processing equipment through a data line or wireless communication. Applied in various commercial cash registers, express logistics, warehousing and transportation, and intelligent manufacturing, it has become an important part of the IoT ecosystem. [0003] In many applications, the ambient light for barcode scanning is insufficient, and barcodes on different media or on different surfaces have different contrast or reflectivity, which poses new challenges for code reading equipment. Although the current barcode scanners are also equipped with auxiliary lighting devices, t...

[0003] In many applications, the ambient light for barcode scanning is insufficient, and barcodes on different media or on different surfaces have different contrast or reflectivity, which poses new challenges for code reading equipment

Although the current code scanners are also equipped with auxiliary lighting devices, they still cannot meet the needs of efficient barcode scanning, especially for barcodes on mobile phone screens and computer monitors. Due to reflections or flares, etc., code reading failures are often caused.
