Abstract
The invention relates to a method for marking laser bar codes. The method comprises the followings steps: inputting bar code parameters into a control system; and generating bar codes with bar zones and blank zones in the control system. The blank zones comprise a group of blank zones formed by all bar zones which are arranged at intervals in turn, a first blank zone in front of a starting bar zone and a second blank zone behind an ending bar zone; the control system controls a laser beam to carry out scanning irradiation of a preliminary marking position to form the blank zones; and the preliminary marking position is of single color. The method ensures that bar codes are read by a bar code scanner more conveniently along with fast marking speed and precise marking.
Description
[technical field]
The present invention relates to a kind of barcode label method, particularly relate to a kind of method with marking laser bar codes.
[background technology]
Bar code is widespread use in modern society, and in the bar code that shows, as shown in Figure 1, the color in bar district is darker than the color of dead zone usually.Method by mode mark bar codes such as printings being arranged in the prior art, adopt this technical mark bar code owing to be subjected to the influence of printing equipment, is can not be put on the printing equipment to operate to some objects, takes typographic(al) mark bar code speed also slow simultaneously.
Also have in the technology now and utilize laser to carry out the method for barcode label, common labeling method is to be labeled the thing background color as the dead zone, and the laser labelling part is as the bar district.Because laser labelling partly mostly is light color on general material, when needs read this bar code, existing barcode scanner was not easy to read this light color bar code, and especially at background colour during as dark object, bar code reads easier makeing mistakes.
[summary of the invention]
In order to overcome above-mentioned the deficiencies in the prior art, the invention provides a kind of method of marking laser bar codes, improve the accuracy that bar code reads.
The technical solution adopted for the present invention to solve the technical problems is: with the parameter input control system of bar code, in control system, generate and have the bar code of bar district and dead zone, second dead zone after described dead zone comprises one group of dead zone, first dead zone before the beginning bar district that all bar districts form successively at interval and finishes the bar district, control system control laser beam scans irradiation to the preliminary making place and forms described dead zone; The color in described district is the color at described preliminary making place; The color of described dead zone is the color that forms after the laser radiation.
The scheme that the present invention solves further technical matters is: described preliminary making place is a solid color.
The scheme that the present invention solves further technical matters is: the bundle point of described laser beam carries out " Z " font scan mode to the scanning irradiation of preliminary making place with the zone of described bar code.
Compared to prior art, the method of marking laser bar codes of the present invention adopts laser beam that irradiation is scanned to form the bar code dead zone in the preliminary making place, because laser radiation zone color is general lighter, therefore, the color in bar code-bar district is generally darker, the bar code of Xing Chenging is discerned by barcode scanner easily like this, therefore, can solve the above-mentioned problem that is not easy correct identification with the direct mark bar code of laser like this.

The bar code diagram that Fig. 2 generates for the present invention.
[embodiment]
Following content be in conjunction with concrete preferred implementation to further describing that the present invention did, can not assert that concrete enforcement of the present invention is confined to these explanations.For the general technical staff of the technical field of the invention, without departing from the inventive concept of the premise, can also make some simple deduction or replace, all should be considered as belonging to protection scope of the present invention.
Because generally, the method for utilizing marking laser bar codes is to be labeled the thing background color as the dead zone, and the laser labelling part is as the bar district.Because laser labelling partly mostly is light color on general material, when background color was dark, the color of bar code dead zone was dark than the color in bar code-bar district, when barcode scanner reads this bar code, existing barcode scanner is not easy to read this light color bar code, also causes the bar code read error sometimes.
The technical scheme that marking laser bar codes of the present invention is taked is: with the parameter input control system of bar code, generate the bar code that meets national standard in control system.In control system, generate and have the bar code of bar district and dead zone, as shown in Figure 2, because beginning of common bar code Yi Tiao district and bar end of extent, for making the postradiation bar code of scanning correct, it is first dead zone 21 that system takes to preset the part dead zone before beginning bar district 11, and presetting the part dead zone after finishing bar district 12 is second dead zone 22.Thus, second dead zone 22 after described dead zone comprises one group of dead zone 23, first dead zone 21 before the beginning bar district 11 that all bar districts form successively at interval and finishes bar district 12, control system control laser beam scans irradiation to the preliminary making place and forms described dead zone.
The color in the bar code-bar district that said process generates is the color with the preliminary making place, and the color of bar code dead zone is the color that forms after the laser radiation.Be the bar code effect that obtains, the color in bar code-bar district should should be obviously darker than the color of bar code dead zone, because the color of general laser labelling is superficial, therefore, the embodiment of this laser labeling method is dark workpiece for described preliminary making place then, is solid color in the color of institute's mark, and solid color refers to other solid color except that white here, described solid color refers to that this place is a kind of color, and the effect of mark is then better like this.
In above-mentioned marking laser bar codes process, the bundle point of described laser beam carries out " Z " font scan mode to the scanning irradiation of preliminary making place with the zone of described bar code, and such scan mode is meticulousr, accurate.
Laser bar code labeling method of the present invention adopts carries out the laser radiation mark to the bar code dead zone, can make things convenient for reading of bar code, and meticulousr with tense marker, signature velocity is also faster.
