Description

Technical Field

[0001] The utility model relates to the technical field of anti-counterfeiting printing variable character recognition, in particular to an anti-counterfeiting printing variable character recognition device. Background Art

[0002] Anti-counterfeiting printing variable characters refer to characters that can change randomly during the printing process to increase the anti-counterfeiting effect. The following are some common anti-counterfeiting printing variable character technologies and applications: Random code: Generate random characters or codes through a certain algorithm. The random code on each product is unique. Consumers can verify the authenticity of the product by querying the random code. QR code: QR code can store a large amount of information, and can obtain relevant information about the product and verify the authenticity by scanning the QR code. Invisible characters: Through special printing technology, the characters are hidden on the surface or back of the printed matter and can only be displayed under certain conditions. Temperature-variable characters: The characters will change color with the change of temperature to increase the anti-counterfeiting effect. Light-variable characters: The characters will change color with the change of the angle and intensity of the light to increase the anti-counterfeiting effect. These anti-counterfeiting printing variable character technologies can be used alone or in combination to improve the anti-counterfeiting effect. At the same time, in order to ensure the reliability of anti-counterfeiting, it is also necessary to combine other anti-counterfeiting measures, such as anti-counterfeiting labels and anti-counterfeiting packaging.

[0003] Anti-counterfeiting printed variable characters are mostly printed on the surface of products that need to be anti-counterfeit, so that purchasers can check whether the purchased products are genuine. Before the products leave the factory, the printed variable characters need to be tested and identified to ensure that the printed variable characters can be used normally. The existing identification method is that the identification personnel hold a scanning gun connected to a computer to scan the products on the conveyor belt of the assembly line one by one. In this identification method, the identification personnel need to hold the scanning gun for a long time, which is inconvenient to use. At the same time, due to the refraction of light, large areas of white light are likely to appear in the image scanned by the scanning gun, which makes it impossible to identify the variable characters, which is inconvenient to use.

The bottom of the identification device 63 is fixedly connected with a fill light belt 65. The top of the identification device 63 is provided with a USB connection port 64.

[0026] In the above embodiment, it should be noted that the anti-counterfeiting product 3 pushes the pressure sensor 74, and after the pressure sensor 74 sends the contact signal to the recognition device 63, the recognition device 63 turns on the recognition camera 66 for recognition and counts the recognition time. At the same time, when the anti-counterfeiting product 3 is located in the box 51, the light-blocking curtains 53 on both sides of the inner cavity of the box 51 block the external light to prevent the external light from entering the box. Under the action of the lighting lamp 55 and the fill light belt 65, the surface of the variable character 4 is illuminated, so that the recognition device 63 recognizes the variable character 4 through the recognition camera 66.
