Automatic laser marking machine

Abstract

The invention discloses an automatic laser marking machine comprising a workpiece rotation device, a workpiece clamp and a laser marking device. The workpiece rotation device comprises a rotation mechanism and an index plate. The index plate is arranged on the rotation mechanism. The rotation mechanism is used for driving the index plate to rotate to convey a workpiece onto a corresponding designated station according to the preset mode. The workpiece clamp is arranged on the index plate and can adjust the clamping range according to the size of the to-be-machined workpiece. The laser markingdevice is used for conducting two-dimensional marking on the workpiece on the station. The laser marking machine provided by the invention is simple to operate, multiple types of different-size workpieces can be marked in batches, the rotation index plate is arranged so that manual operation and maintenance cost can be reduced, and in addition, the position of the laser marking device can be adjusted in three dimensions.

Description

technical field [0001] The invention relates to the field of laser marking, in particular to an automatic laser marking machine. Background technique [0002] The laser marking machine uses a high-energy-density laser to irradiate a certain part of the workpiece to vaporize the surface material or undergo a chemical reaction of color change, thereby leaving a permanent mark. Laser marking machine has many advantages such as high marking precision, fast processing speed, low cost, high level of automation, no mechanical extrusion or mechanical stress damage to processed items, etc., which makes the application of laser marking machine more and more extensive. [0003] A traditional laser marking machine includes a laser, a beam expander lens group, a vibrating mirror, a field mirror, a workbench and a control computer. When using this traditional marking machine for processing, it is necessary to place the workpiece to be processed on a lifting table, and place a metal sheet...

AI Technical Summary

Problems solved by technology

When using this traditional marking machine for processing, it is necessary to place the workpiece to be processed on a lifting table, and place a metal sheet on the workpiece to be processed, finely adjust the lifting table until the processing surface is found, and then remove the metal sheet to be processed. Processing, such an operation process is very troublesome

In addition, when it is necessary to mark some special products (such as products with different diameters or inconsistent heights), it is necessary to adjust the fixture or replace the fixture cumbersomely, which brings a lot of inconvenience
