Abstract
The invention provides a method for making a logistics tracing mark and a method for reading the same. The methods include the steps: a, evenly spraying UV absorption coating of specific absorption band UV to a mark area, used for making the mark, of the surface of an object; b, curing the UV absorption coating in the mark area; c, carving the mark area to obtain a recognizable dent used for marking the object, and removing the part, at the recognizable dent, the UV absorption coating; d, exposing the mark area to a specific band UV source to allow the UV absorption coating in the mark area to absorb the UV and the recognizable dent to reflect the UV; e, imaging the UV reflected by the recognizable dent on a sensor through a filter, and displaying an image on a reader. A step of removing water drops and impurities on the mark area on the surface of the object is performed before the step a. The methods have the advantages that the unique mark area resistant to erasure or wiping is formed on the surface of the object, and the influence of variety changes or pattern changes upon the recognition rate is decreased.

Accompanying drawing explanation
By the description to embodiment below in conjunction with accompanying drawing, above-mentioned feature of the present invention and technological merit will become apparent and easily understand.In the accompanying drawings,
Fig. 1 is the label creating of reviewing for logistics described in one embodiment of the invention and the schematic flow sheet of reading method thereof.
Embodiment
For above-mentioned purpose of the present invention, feature and advantage can be become apparent more, below in conjunction with the drawings and specific embodiments, the present invention is further detailed explanation.
Fig. 1 is the label creating of reviewing for logistics described in one embodiment of the invention and the schematic flow sheet of reading method thereof.As shown in Figure 1, the first step be to body surface for making the tag slot of mark, be dried abatement processes, remove water droplet and the impurity be positioned at tag slot.Conventionally, adopt the equipment such as high-power hair-dryer or hairbrush to remove the impurity such as the water droplet of body surface and dust, to keep the dry and clean of body surface.The first step is preferred steps, if tag slot is dry and clean, can omit this step.
Second step is the tag slot of body surface evenly to be sprayed to the water white transparency uv absorption coating of specific absorption wave band, tag slot is different to other positions of object.Preferably, adopt spray unit by the uniform atomizing of uv absorption coating, and be sprayed into tag slot.Preferably, the specific absorption wave band wavelength coverage of uv absorption coating is 200nm ~ 400nm.
The 3rd step be by uv absorption paint solidification in tag slot, uv absorption coating can form the water white film of one deck in tag slot.Preferably, adopt solidified cell by uv absorption paint solidification to tag slot.Solidified cell comprises that ultraviolet curing lamp or other can be for the high temperature drying equipment of uv absorption paint solidification.
The 4th step is that carve, for the indenture identified of marking objects,, is removed because engraving can be identified the uv absorption coating that indenture departs from body surface meanwhile on the tag slot of object; Be that uv absorption coating on the indenture identified of tag slot is eliminated, spill can light reflection ultraviolet material bed, and remaining area is still covered by the uv absorption coating after solidifying.Preferably, adopt laser cell can identify indenture at tag slot engraving, can identify the combination that indenture comprises numeral, letter or bar code or three, can identify indenture is the concrete mark that represents object, and the object of different cultivars can be made the different indentures identified.Utilize laser machine to carve the indenture identified in article mark district, be difficult for by wiping, correction.
The 5th step is the ultraviolet source irradiation tag slot that adopts specific band, and the uv absorption coating of tag slot absorbs ultraviolet light, can identify indenture light reflection ultraviolet.And be carved with the part of character, directly ultraviolet light is reflected back.Preferably, to launch ultraviolet wave band wavelength coverage be 200nm ~ 400nm to ultraviolet source.The tag slot that is covered with uv absorption coating can have stronger receptivity to the ultraviolet light of 200nm ~ 400nm wave band, conventionally, 200nm ~ 400nm wave band ultraviolet light is had to more than 95% absorptivity, and uv absorption coating is thicker, and absorptivity is higher.And be carved with the part that can identify indenture, by uv absorption coating thereon, be eliminated, so, can identify indenture and directly ultraviolet light be reflected back.
The 6th step is can identify the ultraviolet light of indenture reflection by optical filter imaging on sensor, and illustrates on plug-in reader.Optical filtering can be by identifying the ultraviolet light of indenture reflection, and the light of other wave band is stopped and can not pass through by optical filtering.The ultraviolet wave band wavelength coverage of the indenture the identified reflection that preferably, optical filtering passes through is 200nm ~ 400nm.By light imaging on sensor of optical filter, become image be to identify mark shown in indenture.Preferably, sensor comprises charge coupled cell (CCD) or complementary metal oxide semiconductor (CMOS) (CMOS).Plug-in reader is resolved recognition to become image, and another user can intuitively obtain the information of object.Preferably, plug-in reader is to the video recording analysis recognition forming on sensor.
The label creating of reviewing for logistics and reading method thereof that the embodiment providing by the invention described above provides, one, in tag slot, evenly spray uv absorption coating, by laser engraving, remove the uv absorption coating of shell mark indenture top, in tag slot, can form absorb the uptake zone of ultraviolet light and light reflection ultraviolet and for the echo area of mark, increase contrast; Its two, adopt laser equipment engraving can identify indenture, label information is difficult for by wiping or correction, improves the reliability of mark; Its three, under UV-irradiation, tag slot spraying uv absorption coating can increase can identify indenture and the imaging contrast of tag slot remaining area in sensor, plug-in reader is effectively identified identifying indenture; Adopt above-mentioned identification means on various product, to make mark; can adopt a set of identification equipment can distinguish various product; they are four years old; can identify indenture not only can identify by naked eyes; and when computer vision is distinguished; can under same specific light source, identify, can be protected the information containing in tag slot, reduce data by the possibility of other people collection.
The above; be only preferably embodiment of the present invention, but protection scope of the present invention is not limited to this, any people who is familiar with this technology is in the disclosed technical scope of the present invention; the variation that can expect easily or replacement, within all should being encompassed in protection scope of the present invention.Therefore, protection scope of the present invention should be as the criterion with the protection domain of claim.
