Abstract

The invention discloses a coding method based on laser etching, which belongs to the field of automation, and the technical scheme is characterized by comprising the following steps: the method comprises the following steps: the laser coding machine is fixedly connected with the numerical control cutting machine, and data exchange is realized, so that automatic etching coding on the surface of the part is realized by driving of a numerical control program; step two: the automatic spraying equipment is fixedly connected with the numerical control cutting machine, is driven by a numerical control program, automatically sprays, forms a zinc film with a certain thickness at the appointed position of the part, and generates a required part code by etching the zinc film through the laser coding machine. Compared with the traditional numerical control cutting, the invention realizes the circulation of the part information, the numbering information is reserved from the typesetting CAD file to the component, the whole process circulation of the part information is facilitated, and the problems that the numbering of the part needs to be manually written, no information circulation exists and the traceability is unavailable are solved. The laser etching has the characteristic of high efficiency, and is more attractive and quicker than the traditional handwriting coding and ink-jet coding technology.

Description

Encoding method based on laser etching

Technical Field

The invention relates to the technical field of automation, in particular to a coding method based on laser etching.

Background

The numerical control cutting of metal is a mature technology, but traditional numerical control cutting machine only has the cutting route, can not number the part, does not realize the circulation of information, can not realize the traceability of part, and the serial number of part adopts artifical the writing also very pleasing to the eye usually in addition.

For this purpose, a coding method based on laser etching is proposed.

Disclosure of Invention

The main objective of the present invention is to provide a coding method based on laser etching to solve the above problems in the background art.

In order to achieve the above object, the present invention provides a coding method based on laser etching, comprising the steps of:

the method comprises the following steps: the laser coding machine is fixedly connected with the numerical control cutting machine, and data exchange is realized, so that automatic etching coding on the surface of the part is realized by driving of a numerical control program;

step two: the automatic spraying equipment is fixedly connected with the numerical control cutting machine, is driven by a numerical control program, automatically sprays, forms a zinc film with a certain thickness at the appointed position of the part, and generates a required part code by etching the zinc film through the laser coding machine.

Further, in the second step, the method comprises the following specific steps:

s1, pre-compiling a nesting and typesetting program of the cut parts, wherein information such as cutting paths, part numbers and the like are set in the program;

and S2, automatically moving the numerical control cutting machine to a specified position according to the instruction requirement of the program, and spraying a paint area with a preset size.

Further, the method also comprises the third step of: the protective cover is welded outside the laser coding machine and the automatic spraying equipment, so that the equipment is prevented from being influenced by high temperature and dust when the parts are cut.

By applying the technical scheme of the invention, the beneficial effects are as follows:

1. compared with the traditional numerical control cutting, the invention realizes the circulation of the part information, the numbering information is reserved from the typesetting CAD file to the component, the whole process circulation of the part information is facilitated, and the problems that the numbering of the part needs to be manually written, no information circulation exists and the traceability is unavailable are solved.

2. The laser etching has the characteristic of high efficiency, and is more attractive and quicker than the traditional handwriting coding and ink-jet coding technology.
