Embodiment Construction
[0025] The structure of the driving device of the light-emitting part 40 of the barcode reading device in the preferred embodiment of the present invention is as follows: figure 1 As shown, it includes a fixed frame 10 on which a vibrating support 20 for connecting a light-emitting component 40 of a barcode reading device is arranged. The driving device also includes a vibration source 30. The vibration source 30 drives the vibration support 20 to vibrate to drive the code reading light 41 sent by the light-emitting part 40 of the barcode reading device to reciprocate. The barcode 50 in the reciprocating movement of the code reading light 41 can expand the reading range and improve the success rate of decoding, especially suitable for occasions where the positions of the barcode reading equipment and the barcode 50 to be read are relatively fixed and cannot be moved. For example, when the code reading light 41 is in the figure 2 Move between position A and position B on the ...

The invention relates to a bar code reading facility and a light-emitting component driving device thereof. The driving device comprises a fixing frame and a vibration source, wherein the fixing frame is provided with a vibration bracket for being connected with light-emitting components of the bar code reading facility, and the vibration source is used for driving the vibration bracket to vibrate so as to enable code-reading light emitted by the light-emitting components of the bar code reading facility to make a reciprocating motion. The driving device provided by the invention can drive the light-emitting components of the bar code reading facility to vibrate, so that the code-reading light emitted by the light-emitting components can make a reciprocating motion so as to facilitate bar code reading, thereby improving the bar code decoding success rate of the bar code reading facility in case of contamination, breakage, incompleteness, partial fuzziness or the like. Thus, the invention is especially applicable to the situation that the bar code reading facility and the bar codes to be read are arranged in relatively fixed positions and can not be moved.
Description
technical field [0001] The invention relates to the technical field of barcodes, more specifically, to a barcode reading device and a driving device for a light-emitting component thereof. Background technique [0002] Barcodes can be seen everywhere in our lives. Barcodes were proposed by Americans in 1949. Later, with the development of science and technology, barcodes have been well applied. The barcode reading equipment is to reflect the light irradiated on the barcode symbol and then image it on the converter through the optical system, convert the optical signal into an electrical signal, and convert the barcode symbol into a number that we can understand through program decoding. , letters, characters, etc. [0003] When the one-dimensional barcode reading equipment reads the barcode, the barcode may be stained, broken, incomplete, or partially unclear due to the printing, production and use of the barcode. The light used by the current barcode reading equipment for...
