Method and device for manufacturing two-dimensional code by laser scanning etching

Abstract

The invention discloses a method and a device for manufacturing two-dimensional codes by laser scanning and etching. The device includes a metal film, a metal film fixing plate, a semiconductor laser component, a mechanical control system device, and a semiconductor laser moving area; The film is fixed on the plate; the semiconductor laser moving area is located on the mechanical control system device; the mechanical control system device controls the semiconductor laser component to scan and etch the two-dimensional code pattern on the metal film. The method includes: fixing the metal film; reading the two-dimensional code information to be etched, and determining the size of the metal film; using a mask to process the public area of ​​the two-dimensional code; dividing the area on the metal film; oxidizing the metal film; Adjust the coordinates of the metal film and semiconductor laser; etch the two-dimensional code pattern in the information area. The invention etches the first positioning area, the second positioning area, the third positioning area and the auxiliary positioning area on the metal thin film, further accelerating the etching speed of the two-dimensional code.

Description

technical field [0001] The invention relates to the fields of computer software, information technology, network technology and the like, in particular to a method and a device for manufacturing a two-dimensional code by laser scanning and etching. Background technique [0002] Two-dimensional code technology is widely used. China adopts the technical specifications of two-dimensional code PDF417, QRCCode, Data Matrix, MaxiCode, Code 49, Code 16K, Code One, two-dimensional code grid matrix code (SJ / T 11349-2006) and Two-dimensional code compact matrix code (SJ / T 11350-2006). Two-dimensional code printing and preparation technology is also gradually mature, and there are many special application occasions, which still need to be developed and researched in order to be more widely promoted and applied. At present, in the process of commodity transactions, commodity QR codes are mainly printed and printed, and have been widely used. However, there is no single QR code applicat...

Problems solved by technology

At present, in the process of commodity transactions, commodity QR codes are mainly printed and printed, and have been widely used. However, there is no single QR code application for a single commodity. The main problem is that if a single QR code is used for a single commodity Two-dimensional code, the workload of printing and printing is very large, whether it is the production cost, or the process of assembly, packaging and pasting is extremely complicated, and it is technically difficult to realize. The present invention provides a laser printing two-dimensional Two-dimensional code technology can solve the technical problem of a single product with a single two-dimensional code
