Description
Technical field
The present invention relates to bar code scan technical field, relate in particular to a kind of comprehensive high-rate laser bar code scanner.
Background technology
Bar code scanner, also referred to as bar-code reader, bar code scan rifle, bar code scanner, barcode scanner etc., be a kind of optical principle of utilizing, will after the information decoding comprising of bar code, by data line or wireless mode, be transferred to the equipment of the devices such as computing machine.Bar code scanner identification is accurate, data high input speed, and equipment is simple, cost is lower, is widely used in a plurality of fields such as business POS (Point Of Sale, point-of-sale terminal) POS, supermarket, express delivery, storage, logistics, books, medicine.
Different according to light source, bar code scanner can be divided into rainbow optical bar code scanner and laser (Laser, transliteration is radium-shine) barcode scanner.Rainbow optical bar code scanner is also referred to as CCD(Charge-coupled Device, charge coupled cell) imageing sensor, be to utilize photoelectric coupling principle, bar code printing pattern is carried out to imaging, and then decoding, its advantage be without rotating shaft, the life-span is long and cost is low; And laser bar code scanner is to utilize laser diode as the single-line type scanner of light source, it is all better than rainbow optical bar code scanner in sweep velocity, scanning distance, scan sensitivity etc., thereby having obtained application more widely, the scanner of main flow is laser bar code scanner in the market.
Traditional laser bar code scanner is provided with single LASER Light Source, and in LASER Light Source around according to actual needs, on different angles of inclination, arrange a plurality of reflecting optics, middle position at above-mentioned a plurality of reflecting optics is provided with a polygonal mirror simultaneously, this polygonal mirror rotates under the driving of motor or motor, thereby realize by the formed multi-faceted scanning linear light net of single light source, as shown in Figure 1, can utilize this multi-faceted scanning linear light net to read the bar code information of carrying out to be measured.This traditional laser scanning device only can form scanning linear light net in limited angle, and number of scanning lines is less, in each predetermined angle, there are many single sweep traces 10, bar code to be measured must be placed on suitable angle in scanning linear light net and just can be correctly validated, and has affected the effect that bar code reads.
Because laser scanning device is single-line type scanner, and one of key factor that affects bar code reading effect is the quantity of laser scanning line, be laser scanning device when projecting scanning linear light net to bar code to be measured, the quantity of the laser scanning line that this scanning linear light net projected in each moment has determined the recognition effect of this bar code to a great extent.As a rule the quantity of sweep trace is more, and the scanning effect of this device is better.
In order to improve the scanning effect of laser bar code scanister, Chinese patent (application number: the variable scanister and the method that 200310101759.0) have proposed a kind of laser bar-code reading apparatus, it is mainly by arranging a variable drive unit, make the polygonal mirror of the middle position in scanister, with an oscillation centre, carry out the swing of predetermined variable angle and predetermined hunting frequency, thereby make each laser scanning line derive many sweep traces that are parallel to each other with it, as shown in Figure 2, if using original sweep trace 10 as datum line 10, after the improvement of this scheme, each datum line 10 all will derive many sweep traces that parallel with it 11.Therefore, the technological means that this technical scheme adopts is each sweep trace by doubling in original scanning linear light net, increases the sweep trace quantity of laser scanning device.
Although technique scheme has increased the quantity of laser scanning line, improved bar-code identification effect, but because it only repeats to increase the quantity of existing sweep trace in original scanning linear light net, therefore only can in limited angle, form scanning linear light net, scan the scanning angle that linear light net covers and still fail to reach the comprehensive covering of 360 degree, can sweep limit little, the below of scanning linear light net is as shown in Figure 2 scan blind spot, bar code to be measured still need to be placed in scanning linear light net with certain angle and correct position, with alignment scanning line, just can be correctly validated, bar-code identification effect and property easy to use have been affected, and the slower defect of the sweep velocity of single LASER Light Source is still unresolved.
