Description
Technical Field
The utility model relates to an anti-counterfeiting technology, in particular to an infrared invisible code reading device.
Background
Along with the activity of the current market economy, the anti-counterfeiting technology is continuously updated and developed. The anti-counterfeiting of the commodities mostly uses label paper products as anti-counterfeiting labels and is adhered to the surfaces of the commodities, and the anti-counterfeiting technology not only can easily tear and damage the labels, but also influences the appearance beautification of the commodities. The anti-counterfeit label is damaged and torn frequently, which not only damages the benefit of the manufacturer and the rule, but also causes the credit of the brand party to be damaged, so that the goods fleeing and anti-counterfeit of the commodity must be controlled by other technologies.
In intense market competition, the appearance of the package has a great impact on the consumer for the same product. Therefore, production merchants prefer to pack commodities into bright-colored and attractive colors, and do not want to spray black paint bar codes on the surfaces of the packages, so that the overall attractiveness of the packages is affected, and the purchasing desire of consumers is reduced. Therefore, production merchants prefer to use the invisible code anti-counterfeiting technology, the desire of consumers to purchase commodities is improved, and the circulation of fake commodities is avoided. In addition, because the purchasing desire of the consumer is dominated by the truth and falseness of the commodity, if the consumer purchases the counterfeit commodity, the credit of the commodity is influenced, the consumer reduces or does not purchase the commodity at all, and the profit of the producer is reduced. For example, in recent years, the inundation of counterfeit goods is not only limited, but also the upgrading of anti-counterfeiting technology is imminent.
The prior anti-counterfeiting printing technology comprises two types, namely dominant and recessive. The dominant anti-counterfeiting technology is that the anti-counterfeiting pattern is dominant, and consumers can observe the anti-counterfeiting pattern by naked eyes without tools, so that the authenticity of the product can be judged. The hidden anti-counterfeiting technology is to hide the anti-counterfeiting pattern, so that the anti-counterfeiting pattern cannot be seen by naked eyes, and the anti-counterfeiting pattern can be observed by means of a special tool.
The optical design of typical invisible anti-counterfeiting two-dimensional code reading equipment utilizes a reflector to break off a light path to reduce the optical length in the normal direction of a detection surface, so that the system is compact and coordinated overall, and simultaneously, the high-quality imaging requirement required by image processing is ensured.
Recently, a hidden code technology for printing anti-counterfeiting patterns by using infrared ink gradually becomes a development direction, and the manufacture and circulation of false anti-counterfeiting labels can be effectively and fundamentally stopped. However, the existing universal invisible code reading equipment has high requirements on the color difference between the material ground color and the anti-counterfeiting pattern, and if the color difference is relatively close, the reading equipment cannot normally read the anti-counterfeiting pattern. The bottom color of the material needs to be strictly controlled by a production merchant, but the bottom color of most commodities is dark color or bright color which is favored by consumers, which usually affects the reading of reading equipment, and the current universal reader is difficult to accurately and effectively read the anti-counterfeiting pattern, thereby affecting the desire of manufacturers to control the production and manufacture of counterfeit and shoddy products by adopting the invisible code technology. Meanwhile, for attractiveness, a plurality of types of reflective materials are adopted in a plurality of packaging materials, when infrared invisible codes are sprayed on the surfaces of the materials and read by using common infrared invisible code reading equipment, serious reflection can occur, so that the equipment cannot obtain accurate and clear electronic images, and the capability of a consumer for inquiring the authenticity of commodities is influenced.
The applicant patent application No. 2020112459964 provides a invisible code recognition device for the surface of a reflective packaging material, which comprises a shell, an electronic image processing module and an electronic camera, wherein the electronic image processing module and the electronic camera are arranged on the shell and comprise an electronic recognition module; the electronic camera adopts a conical lens, the conical lens is right opposite to the opening of the shading baffle, the installation angle of the lens is the minimum angle for avoiding the original image of the lens, the observable range on the surface of the reflective packaging material is about 15 x 10mm, and the range can be properly adjusted according to the design size of the invisible codes.
