Machined metal workpiece automatic identification method based on 3D printed quick response code

Abstract

The invention discloses a machined metal workpiece automatic identification method based on a 3D printed quick response code. A metal 3D printer is applied to complete making of the quick response code, the method comprises the following steps that powder (6) is prepared; a pattern of the quick response code is designed; a substrate plate (8) is fixed on a working table board (7); the prepared powder (6) fills a powder falling hopper (5); an equipment control system (3) is used for controlling a path of red light scanning in a laser; a red light switch (2) of the laser is turned off, a laser switch (4) of the laser is turned on, powder layers are subjected to laser scanning and sintering, and the required quick response code is formed by accumulating the powder layer by layer; and the printed quick response code is embedded into a machined metal workpiece. According to the machined metal workpiece automatic identification method, the problems that the quick response code which is directly etched in the machined workpiece is low in depth and difficult to identify are avoided, and the problem that the quick response code cannot be identified due to the fact that the machined workpiece is corroded, cracked or deformed when reaction occurs in the heat treatment process of the machined workpiece is avoided as well.

Description

technical field [0001] The invention belongs to the technical field of metal processing identification, and more specifically relates to an automatic identification method for metal processing parts based on 3D printing two-dimensional codes. Background technique [0002] In modern industrial production, metal molds, parts and other processed parts are mass-manufactured, and need to be quickly transported or sorted in stock. However, there are many types of metal processing parts, and the materials, production processes, and quality requirements are not the same. Quickly identify and obtain the specific information of molds or parts, which is of great significance to the rapid screening, classification and deployment of molds and parts. [0003] The traditional identification and classification methods are manually identified and classified, which is time-consuming, labor-intensive and costly. The two-dimensional code (also known as QR Code, QR full name Quick Response) tec...

Problems solved by technology

[0004] Aiming at the above defects or improvement needs of the prior art, the present invention provides an automatic identification method for metal processing parts based on 3D printing two-dimensional codes. The two-dimensional codes are attached to the surface of the parts in the form of inlays, which avoids directly Etched two-dimensional codes are low in depth and difficult to identify, and avoid the problem of corrosion, cracking or deformation of processed parts during heat treatment, resulting in unrecognizable two-dimensional codes, and realize rapid identification of metal products
