Detailed Description
The technical solution in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention.
As shown in fig. 1 to 2, the barcode scanning device with a light softening plate of the present embodiment includes a bottom cover 11, a decoding board 10, a light softening plate 2, and a window transparent screen 1, which are sequentially connected from bottom to top; the bottom cover 11 is provided with a supporting frame 3 for supporting the light softening plate 2; the window transparent screen 1 is provided with a light-transmitting plate 101, and the light-transmitting plate 101 is provided with a shooting port 102; a fixed cover 4 is arranged on the decoding board 10, the upper part of the fixed cover 4 penetrates through the light softening board 2 to be butted with the shooting port 102, a camera 7 is connected below the fixed cover 4, and the camera 7 is electrically connected with the decoding board 10; a plurality of light supplement lamps 13 are arranged on the upper surface of the decoding board 10 facing the light softening board 2, and the light supplement lamps 13 are electrically connected with the decoding board 10.
Further, the distance between the light supplement lamp 13 and the light softening plate 2 is 2.5-3.0mm, so that the optimal light homogenizing effect is achieved; if the distance between the light supplement lamp 13 and the light softening plate 2 is too short, the light supplement light source is not uniformly distributed, and a glare phenomenon is generated; too far distance between the light supplement lamp 13 and the light softening plate 2 can cause the light source to be too dark, reduce the definition of a scanned image and reduce the recognition speed.
