Description
Technical field
The utility model belongs to the information acquiring technology field of bar code, especially a kind of device that simultaneously can read multiple different bar code information.
Background technology
Bar code (barcode) is the multiple secret note and blank that are not waited by width, according to the arrangement of certain coding rule, in order to express the graphical identifier of one group of information.Common bar code is the pattern of parallel lines that the secret note that differed greatly by reflectivity and informal voucher are lined up.Bar code can mark the much information such as producing country, manufacturing firm, trade name, date of manufacture of article, is thus widely used at commodity circulation.
Existing bar code reads technology and mainly contains laser scanner scanning and to read and CCD takes pictures reading two kinds of modes, laser scanner can only realize the reading of single bar code, when in the face of with the commodity of multiple bar code, such as: by multiple identical goodses that transparent packing bag is packaging together, or posting certain the part commodity of the new and old bar code recording different information, is also once namely stop after effectively reading a bar code reading.Though and CCD take pictures read can take multiple bar code simultaneously, but then the later stage needs corresponding OCR software to analyze multiple bar code gives up unnecessary bar code, there is the deficiency that efficiency is low, cost is high in such reading manner.
Some needs to carry out to product the field that logistics reviews, the medicine that such as hospital issues, all corresponding bar code can be pasted in different links, cause article existing simultaneously multiple effective different bar code, just need when carrying out information acquisition like this to read multiple different bar code, but the bar code scanner that prior art provides cannot realize above-mentioned functions simultaneously.
Utility model content
The purpose of this utility model is to overcome the deficiencies in the prior art, provide a kind of based on laser generator, the reading device identifying multiple different bar codes be arranged in parallel can be read simultaneously.
The utility model solves the technical scheme that its technical matters adopts: a kind of multiple barcode reading device, comprise housing and be located at the cover plate in housing forward end face, housing underside is connected with base, housing bottom is provided with transmission circuit plate, case top is provided with concave mirror and catoptron, concave mirror is provided with collector lens, laser generator and inductor is provided with above transmission circuit plate, laser generator is provided with laser lens, laser generator rear is provided with rotating mirror, rotating mirror is fixed on housing by wig-wag, described catoptron is single-surface mirror, described rotating mirror is multifaceted prism.
Described a kind of multiple barcode reading device, its rotating mirror is kaleidoscope prism.
Described a kind of multiple barcode reading device, its housing is square, rectangular parallelepiped or semisphere.
Described a kind of multiple barcode reading device, its wig-wag comprises rotation axis, magnet and coil.
Described a kind of multiple barcode reading device, its transmission circuit plate is wireless transmit output circuit or infrared emission output circuit.
The beneficial effects of the utility model are: catoptron is one side, rotating mirror is N face prism, the laser that laser generator sends obtains N bar parallel lines after the prism of N face, emit through catoptron again, thus multiple different bar codes arranged in parallel can be read simultaneously, and recognition capability more by force, faster, good stability, cost are low.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model;
Fig. 2 is cut-away view of the present utility model.
Each Reference numeral is: 1-housing, 2-cover plate, 3-base, 11-transmission circuit plate, 12-concave mirror, 13-laser generator, 14-laser lens, 15-rotating mirror, 16-catoptron, 17-inductor.
Embodiment
Below in conjunction with accompanying drawing, the utility model is described in further detail.
With reference to Fig. 1, shown in Fig. 2, the utility model discloses a kind of multiple barcode reading device, comprise square, rectangular parallelepiped or hemispheric housing 1 and be located at the cover plate 2 of housing 1 front end face, housing 1 underside is connected with base 3, transmission circuit plate 11 is provided with bottom housing 1, described transmission circuit plate 11 is wireless transmit output circuit or infrared emission output circuit, housing 1 top is provided with concave mirror 12 and catoptron 16, concave mirror 12 is provided with collector lens, laser generator 13 and inductor 17 is provided with above transmission circuit plate 11, laser generator 13 is provided with laser lens 14, laser generator 13 rear is provided with rotating mirror 15, rotating mirror 15 is fixed on housing 1 by wig-wag, described wig-wag comprises rotation axis, magnet and coil, described catoptron 16 is single-surface mirror, described rotating mirror 15 is multifaceted prism.Magnetic field is produced during coil electricity, magnet starts left and right tentering and swings under magnetic fields, thus driven rotary mirror 15 rotates, moving axis tentering swings, when laser generator 13 and wig-wag are started working, laser generator 13 is for generation of the laser of 650nm or other wavelength, laser lens 14 is polymerized to for the laser produced by laser generator 13 a bit to be beaten at catoptron 16, continue after wig-wag work to swing back and forth in an angular range, catoptron 16 and wig-wag combine and laser are gone out with fixing direction, due to the high speed reciprocally swinging of wig-wag, make originally to be that any laser becomes to look it is a reciprocal back and forth sweep trace, collector lens is for receiving the optical signalling reflected, collector lens secures the focal length of laser lens 14 simultaneously, the focus of collector lens 14 can accurately be gathered on inductor 17, sweep trace reciprocal is back and forth radiated at above bar code, because the bar of bar code is different to the emittance of laser with sky, the optical signalling of reflection is finally focused on the inductor of circuit board by collector lens, inductor 17 receives signal and carries out opto-electronic conversion, become electric signal and obtain barcode data after shaping amplification is filtered, due to catoptron 16 for one side catoptron only has one, rotating mirror 15 is N face prism, the laser that laser generator 13 sends obtains N bar parallel lines after the prism of N face, emit through catoptron 16 again, thus multiple different bar codes be arranged in parallel can be read simultaneously,
As a kind of specific embodiment, described rotating mirror 15 is kaleidoscope prism, so just can obtain four parallel lines.
Above-described embodiment is illustrative principle of the present utility model and effect thereof only; and the embodiment that part is used; for the person of ordinary skill of the art; under the prerequisite not departing from the utility model creation design; can also make some distortion and improvement, these all belong to protection domain of the present utility model.
