As shown in fig. 1-2, the tobacco anti-counterfeiting two-dimensional code identification equipment comprises a shell 1, a control device, an identification module 5, a zooming component and a laser distance sensor, wherein an identification channel 2 is arranged on the shell 1, the control device, the identification module 5, the zooming component and the laser distance sensor are all arranged in the identification channel 2, the control device is respectively and electrically connected with the identification module 5, the zooming component and the laser distance sensor, and the identification module 5 and the laser distance sensor act on the same direction;
because the common code scanning gun for identifying the two-dimension codes of the commodity is only provided with the identification module 5, the two-dimension codes are identified through the identification module 5, however, the common code scanning gun is only provided with a fixed focal length, the code scanning can be carried out only in a fixed distance range, so that the code scanning can not always succeed at one time, the code scanning gun is gradually close to the identification module 5 of the code scanning gun from far to near, the code scanning gun provided with the zoom module in the prior art can realize the code scanning at different distances through the zoom module, but the focusing identification is mainly realized through passive zooming, namely phase zooming and contrast zooming, the two-dimension codes are required to be used under good light conditions, the identification module 5 continuously adjusts the focusing point until the image becomes clear, the zooming mode has poor using effect under the condition of weak light or complex light, the focusing accuracy is often low;
therefore, in order to improve the accuracy of the two-dimension code identification equipment zooming, the existing passive zooming is improved to active zooming, the active zooming mainly identifies the distance of an identified object through a laser distance sensor, the distance can be detected without depending on light due to laser focusing, the distance to the detected object is calculated mainly through emitting laser and detecting the round-trip time of the laser, then the detected distance information is transmitted to a zooming component through a control device, the zooming component is enabled to be adjusted to a corresponding focal length according to the distance, the identification module 5 can acquire clear images after zooming through the zooming component, and the identification of the two-dimension code can be achieved within a larger distance range.
The zoom assembly mainly comprises a lens barrel, a main lens 6, a zoom lens 7, a screw rod 8 assembly and a first motor 9, wherein the main lens 6 and the zoom lens 7 are respectively provided with a main frame and a zoom frame, the main lens 6 is fixed in the lens barrel, the zoom frame is in sliding fit with the inner wall of the lens barrel, one side of the lens barrel is provided with a sliding groove, the zoom frame is connected with a sliding block 10 on the screw rod 8 assembly through the sliding groove, the sliding block 10 is provided with a through hole, and a driving shaft of the first motor 9 is in transmission connection with the screw rod 8 assembly;

Although the laser distance sensor is used for detecting the distance, and the laser distance sensor is independent of the lighting condition and can be used in an environment with poor light conditions, the recognition module 5 needs better light to recognize the two-dimensional code, so that the recognition device can realize corresponding zooming under the dim light condition, but the recognition module 5 cannot recognize, in order to solve the problem, in one embodiment, a spotlight 3 is further arranged in the recognition channel 2, the spotlight 3 is electrically connected with the recognition module 5 and acts on the same direction, and the spotlight 3 is in linkage fit with the recognition module 5;
under the light condition that the recognition module 5 can normally recognize the two-dimension code, the spotlight 3 does not need to be started, and in the environment with poor light condition, when the recognition module 5 can not recognize the two-dimension code, signals are output to the spotlight 3, and the light of the spotlight 3 irradiates on the position of the two-dimension code of the cigarette, so that the illumination intensity of the local position is enhanced to facilitate the recognition of the recognition module 5.
Since the spotlight 3 and the recognition module 5 are disposed at different positions of the recognition channel 2, in order to prevent the spotlight 3 from shielding the recognition module 5, the spotlight 3 and the recognition module 5 are staggered or are disposed at positions parallel to each other in the recognition channel 2, so that the light of the spotlight 3 is accurately projected onto the recognition position of the recognition module 5, and therefore, the spotlight 3 needs to have a certain inclination angle, when the two-dimensional code of the cigarette is located in the intersection range of the recognition circuit of the recognition module 5 and the projection circuit of the spotlight 3, the inclination angle can ensure that the light of the spotlight is projected onto the two-dimensional code, and when the two-dimensional code of the cigarette is relatively close or relatively far, the two-dimensional code of the cigarette is not located in the intersection range of the recognition circuit of the recognition module 5 and the projection circuit of the spotlight 3, the light of the spotlight 3 is staggered with the two-dimensional code, and thus the light enhancement effect of the recognition module 5 cannot be realized, and in order to solve this problem, in one embodiment, the spotlight 3 is rotationally connected to the housing 1, the second motor 4 is in transmission connection with the spotlight 3, and the second motor 4 is electrically connected with the control device;
through the electrical connection of second motor 4 and controlling means, after distance information is detected to the distance sensor, transmit to controlling means on, controlling means sends rotation signal again for second motor 4, second motor 4 adjusts corresponding angle according to the distance that laser distance sensor detected, when the distance of two-dimensional code is farther, then second motor 4 rotates and makes spotlight 3's angle grow, makes spotlight 3 can throw more distance on, when the distance of two-dimensional code is nearer, then second motor 4 rotates and makes spotlight 3's angle diminish, makes spotlight 3 can throw more distance on.
