Barcode reading equipment pcb circuit board structure

Abstract

The invention discloses a bar code recognition device PCB circuit board structure, comprising a main board, an auxiliary board, a connection support and a communication line; the main board and the auxiliary board are fixedly connected through the connection support; and the communication line is used for communication between the main board and the auxiliary board. The invention can solve the problems of light loss caused by the retroreflector adopted in the current technology, increased optical aberration and the influence on the imaging quality and also can solve the problems that the light is severely deviated from a decoding plane because the retroreflector is not used, which causes the low decoding efficiency, and that the prompting sound is weak, the required strength of the hand-grabbing trigger force is big and the user experience is poor.

Description

technical field [0001] The invention relates to a PCB circuit board structure, in particular to a PCB circuit board structure of a barcode reading device. Background technique [0002] As a high-tech product closely integrating optical, mechanical, electronic, software application and other technologies, barcode reading equipment is the third generation of main computer input equipment after keyboard and mouse. Since the birth of scanning guns in the 1980s, they have developed rapidly and been widely used. From the most direct pictures, photos, films to various drawings, graphics and manuscript materials, they can be input into the computer with scanning guns, and then these images can be scanned. The processing, management, use, storage or output of information. [0003] In barcode reading equipment, PCB circuit board (printed circuit board) is used as the carrier of electronic components and provides electrical connection; through layout design, it can greatly reduce wiri...

Problems solved by technology

[0005] The technical problem to be solved by the present invention is to provide a PCB circuit board structure of a barcode reading device, which has a compact structure, and can solve the light energy loss caused by the use of reflectors in the prior art without increasing the structural volume of the PCB circuit board, which increases the Aberration and the problem of affecting the image quality can also solve the problem of not using a reflector so that the light seriously deviates from the decoding plane, resulting in low decoding efficiency, as well as the weak prompt sound and the required trigger force of the hand, and the poor user experience.
