Description

Technical Field

[0001] The present invention relates to the technical field of product traceability marking processing, and more specifically, to a puncturing assembly for invisible code encoding and a rendering dot matrix device having the same. Background Art

[0002] With the development of society, consumers pay more and more attention to the right to know whether the products they purchase are regular products sold through legal channels and whether the products can be traced. Due to the high illegal income obtained by a small number of lawbreakers, for example, counterfeiting and illegal reselling of cartons of cigarettes in the tobacco monopoly industry, it has caused a major impact on the industry. To solve this problem, the traditional method is to use laser engraving and spraying invisible ink to achieve encoding. However, the traditional method has the defects that the laser engraved information can be maliciously erased and tampered with by lawbreakers, and the invisible ink information can be erased by diluting the solvent.

[0003] In order to overcome the defects of the existing technology, the inventor considered using a puncturing needle to penetrate the packaging surface film through micropores and render and attach the invisible dot matrix encoding information to the surface layer of the cigarette carton to form an invisible code. For example, when performing puncturing encoding on a cigarette carton, it is an information set that integrates with the cigarette carton. This increases the difficulty of information tampering. For example, if the entire surface of the cigarette is torn, it will be difficult to achieve sales. Tampering with the information will surely damage the surface layer of the cigarette carton, thus eliminating the problem of code destruction.

[0004] However, when using the puncturing method for encoding, due to different puncturing contents and requirements, different requirements for the spacing of the puncturing needles are also different. Using a robotic arm alone to control the puncturing needles has extremely low puncturing efficiency, is not conducive to mass production, and has a high structural cost; the dot matrix structure composed of multiple puncturing needles is not easy to adjust the spacing. And a puncturing device that can overcome the above disadvantages is also a difficult point for the existing technology.

[0005] Therefore, how to provide a puncturing assembly for invisible code encoding and a rendering dot matrix device having the same is an urgent problem to be solved by those skilled in the art. Summary of the Invention
