Abstract

The invention discloses a device for generating a two-dimension code in a transparent body. The device mainly comprises an all-solid-state laser, a light beam scanning deflection device, a linear transmission band and a transparent body workpiece to be machined. The light beam scanning deflection device is composed of a Z-axis dynamic focusing module, an X-axis scanning lens, an X-axis digital servo motor, a Y-axis scanning lens and a Y-axis digital servo motor. The dynamic focusing module is composed of a Z-axis linear motor, a concave lens and a convex lens. A laser beam emitted by the all-solid-state laser is focused in the middle of the transparent body workpiece to be machined through the light beam scanning deflection device, the interior of the transparent body workpiece to be machined is marked with an original two-dimension code image processed by color inversion, and then the laser machining of the two-dimension code in the transparent body is achieved. The two-dimension code is directly marked in the transparent body, the surface of an article can be prevented from being damaged, and the integrity of the two-dimension code of the article can be guaranteed when the article is used and transported. The appearance and the recognition effect of the two-dimension identification of the transparent body are improved, and the device has wide application value in the product source and the anti-fake aspects.

Description

technical field [0001] The invention relates to a device for generating a two-dimensional code inside a transparent body, in particular to a device for generating a two-dimensional code inside a transparent body based on laser internal engraving technology, and belongs to the technical field of laser processing. Background technique [0002] Item direct object traceability technology is a kind of automatic identification and information management technology that directly records machine-readable two-dimensional code information on items for item traceability management. Together with RFID and other technologies, it has become an Internet of Things technology in manufacturing An important supporting technology for industrial applications. In recent years, with the development of two-dimensional code itself, reading technology and laser technology, the two-dimensional code generated by laser fine marking technology has gained more and more recognition as the main info...
