Detailed Description

The present utility model will be described in further detail with reference to the drawings and examples, in order to make the objects, technical solutions and advantages of the present utility model more apparent. It should be understood that the particular embodiments described herein are illustrative only and are not intended to limit the utility model, i.e., the embodiments described are merely some, but not all, of the embodiments of the utility model. The components of the embodiments of the present utility model generally described and illustrated in the figures herein may be arranged and designed in a wide variety of different configurations.

Thus, the following detailed description of the embodiments of the utility model, as presented in the figures, is not intended to limit the scope of the utility model, as claimed, but is merely representative of selected embodiments of the utility model. All other embodiments, which can be made by a person skilled in the art without making any inventive effort, are intended to be within the scope of the present utility model.

Referring to fig. 1-3, in an embodiment of the present utility model, a two-dimensional code identification card identification device includes an identification mechanism 1 and a display mechanism 2. The identification mechanism 1 includes an insertion port 11, an identification cavity 12, an illumination light source 13, and an identification camera 14, the insertion port 11 communicates the identification cavity 12 with the outside, and an identification card can be inserted into the identification cavity 12 through the insertion port 11. The illumination light source 13 is provided inside the recognition chamber 12, and can output light to control the brightness inside the recognition chamber 12. The output end of the identification camera 14 is aligned with the inside of the identification cavity 12 for identifying the two-dimensional code. The side wall of the identification cavity 12 is provided with a diffuse reflecting layer 15 capable of covering the identification cavity 12 with light in a diffusely reflecting manner. The display mechanism 2 is electrically connected with the identification mechanism 1 and is used for displaying the digital identity card information on a screen of the display mechanism 2 after scanning the two-dimensional code.

Referring to fig. 2 and 3, the diffuse reflection layer 15 is an optical diffuse reflection coating, well attached to the base material of the side wall of the identification cavity 12, and has a rough reflection surface, so that light incident in one direction can be emitted in a diffuse manner, so that the light is more uniform and softer, and no light spot is formed on the surface of the identification card. The use of paint applied to the side walls of the identification cavity 12 can accommodate different base shapes.

The side wall of the identification cavity 12 is of an arc transition structure, and the structure can reflect light rays to the bottom of the identification cavity 12 as much as possible, so that the radiation flux at the bottom of the identification cavity 12 is increased, and the illumination intensity at the bottom is improved. The diffuse reflective coating is well-conformed to the arcuate transition structure of the side wall of the identification cavity 12.

The bottom of the identification cavity 12 is provided with a clamping groove 121 and a light source mounting plate 122, and the relative height of the bottom of the clamping groove 121 is lower than the relative height of the top of the light source mounting plate 122. When the identification card enters the identification cavity 12 through the insertion port 11, the identification card can be accommodated in the clamping groove 121, and the displacement of the identification card is limited through the clamping groove 121, so that the movement is prevented.

Referring to fig. 3, the identification cavity 12 forms an angle α between the input direction of the insertion port 11 and the horizontal plane, and the angle α is 3 ° to 6 °, and by setting a certain inclination angle at the bottom of the identification cavity 12, the two-dimensional code identification card naturally rests at the bottom of the identification cavity 12 under the action of gravity, and the angle setting is not too large, so as to avoid interference with surrounding components.

Further, a pressure sensor 123 is disposed at one end of the clamping groove 121 away from the insertion opening 11, and the pressure sensor 123 is electrically connected with the illumination light source 13. If the identification card is not arranged in the identification cavity 12, the illumination light source 13 does not work; when the identification card falls into the bottom end of the inclined surface of the clamping groove 121, the illumination light source 13 outputs illumination when the pressure sensor 123 senses pressure change, and two-dimensional code identification is performed, energy can be saved through the arrangement, the illumination light source 13 is prevented from being in an output state all the time, and meanwhile, the light source mounting plate 122 can be prevented from being overheated.

The light source mounting plate 122 is arranged around the clamping groove 121, the illumination light source 13 is mounted on the light source mounting plate 122, the irradiation area of the annular light source is large, and the diffusion is more uniform. The illumination light source 13 is a plurality of LED lamp pearls arranged in an array mode at the top of the light source mounting plate 122, the brightness adjusting range of the LED lamps is wide, the service life is long, the illumination is more uniform due to the array arrangement, and beam light cannot be generated.

Further, the recognition camera 14 uses a fixed focus lens. Because the time spent by the zoom lens in the fixed focus process is long, the fixed focus is difficult, the identification card needs to be fixed again every time, and once the fixed focus cannot be fixed, the characteristic identification is difficult or the identification error is caused. Compared with a zoom lens, the image acquired by the fixed-focus lens is clearer, the feature recognition is more accurate, and the fixed-focus lens can be used for quickly fixing focus because the recognition card cannot move in the recognition cavity 12.

The foregoing is merely illustrative of the structures of this utility model and various modifications, additions and substitutions for those skilled in the art can be made to the described embodiments without departing from the scope of the utility model or from the scope of the utility model as defined in the accompanying claims.
