Detailed Description
To further illustrate the technical means and effects of the present invention adopted to achieve the intended purpose of the present invention, the following detailed description is given with reference to the accompanying drawings and preferred embodiments of the present invention for the golden finger and its specific embodiments, structures, features and effects. In the following description, different "one embodiment" or "an embodiment" refers to not necessarily the same embodiment. Furthermore, the particular features, structures, or characteristics may be combined in any suitable manner in one or more embodiments.
As shown in fig. 1-4, on one hand, an embodiment of the present invention provides a barcode label, including a label body 1 and a barcode 2 located on the label body 1, and the barcode 2 is structurally characterized in that the barcode 2 includes a plurality of barcode units 201 opening on the display surface of the label body 1, and the barcode units 201 extend into the label body 1; the area of the opening of the bar-shaped unit 201 on the display surface is a, the projection area of the bar-shaped unit 201 at any position in the label body 1 on the display surface is B, and B is larger than a.
The surface of the label body 1 facing the light source is a display surface and is used for displaying the bar code 2 under illumination so as to be identified by an identification device.
The strip-shaped unit 201 extends into the label body 1 from the opening, and can extend to a certain depth in the label body 1 to form a wedge-shaped structure or a horn-shaped structure with a small opening and a large inner part; the strip-shaped unit 201 can also penetrate through the label body 1, and the section of the strip-shaped unit 201 along the penetrating direction can be in a wedge shape or a horn shape; in any of the above configurations, the projection area of the display surface of the stripe unit 201 at any position in the tag body 1 is larger than the area of the opening.
The light path diagram of the stripe-shaped unit 201 of an embodiment under the irradiation of a light source is shown in fig. 6. Under the irradiation of the fixed point light source, light enters the strip-shaped unit 201 from the opening and enters along the side wall of the strip-shaped unit 201; as can be seen from fig. 6 and 7, the incident angle of the light on the inner side wall of the stripe-shaped cell 201 of fig. 6 is larger than that of fig. 7, so that less light is refracted, and the brightness of the inner side wall of the stripe-shaped cell 201 is reduced. In the case of the same opening size, the light reflection area of the bar-shaped unit 201 of fig. 6 is larger than that of fig. 7, and since the illumination intensity is inversely proportional to the area, the brightness of the inner side wall of the bar-shaped unit 201 of this embodiment is further reduced. From the actual visual recognition, the bar-shaped unit 201 is a solid part, and the space part of the label body 1 between the bar-shaped unit 201 and the solid part has obvious light intensity change, so that the recognition device can more accurately recognize the bar code 2.
In order to further improve the visual significance of the solid part and the spacing part, the structures of the strip-shaped unit 201 and the label body 1 are also optimally designed.
In the first embodiment shown in fig. 2 and 4, the depth of the strip-shaped unit 201 extending into the label body 1 is h, the width of the opening of the strip-shaped unit 201 on the display surface of the label body 1 is W, and the ratio of W to h is 0.2-0.3; because the width of the opening is far less than the depth of the strip-shaped unit 201, under the condition that the inner wall of the strip-shaped unit 201 is coated with the light absorption layer, the light receiving and light absorption areas are increased, and the brightness contrast of the strip-shaped unit 201 and the interval part is more obvious.
When the ratio of W to h is less than 0.2, the thickness of the label body 1 increases, which is disadvantageous to the manufacture and installation of the label body 1, and the improvement of the contrast between the bar-shaped unit 201 and the spacing portion is not significant.
As shown in fig. 2 and fig. 3, in the second embodiment, the bar-shaped unit 201 is a hollow structure, the thickness of the label body 1 is H, the width of the opening of the bar-shaped unit 201 on the display surface of the label body 1 is W, and the ratio of W to H is 0.2-0.3; adopt hollow out construction, light can be dispersed away towards the direction that deviates from the opening along the lateral wall of wedge structure or tubaeform structure, avoids light refraction to return the opening, makes bar unit 201 and interval part have obvious luminance difference.
In order to make the bar code 2 appear black, different light absorption and reflection layers are adopted for the bar-shaped units 201 and the spacing parts, wherein the light absorption layer coated on the side wall of the wedge-shaped structure or the horn-shaped structure is a black light absorption layer, and the part of the appearing surface except the opening of the bar-shaped unit 201 is coated with a reflection layer.
