Laser marking device and method and storage medium

Abstract

The embodiment of the invention belongs to the technical field of laser marking, and relates to a laser marking device. The laser marking device comprises a laser marking machine and a mounting frame,wherein the mounting frame comprises a mounting column and a rotating arm, a laser head of the laser marking machine is located at one end of the rotating arm, and the rotating arm can drives the laser head to conduct rotating movement along a vertical face based on the mounting column. According to the scheme provided by the embodiment of the invention, by changing the cross arm part of a mounting frame of a laser head in the prior art from an original fixed invariant part to the rotatable rotating arm, the incidence angle of a laser is changed accordingly, under the condition that the costis saved, the outer surface of a to-be-marked product can be marked, the inner surface of the to-be-marked product can also be marked, and the marking range is expanded. The invention further providesa laser marking method and a storage medium for the laser marking device.

Description

technical field [0001] The embodiments of the present invention belong to the technical field of laser marking, and in particular relate to a laser marking device, method and storage medium. Background technique [0002] At present, for the marking of ring-shaped items such as rings, laser marking machines are usually used to mark with a rotary table. The marking of ring-shaped items is divided into outer surface marking and inner surface marking, and rotary marking Generally, the device can only mark the outer surface of the ring-shaped object, but cannot mark the inner surface; while there is a type of rotating table with adjustable angle that can realize the marking on the inner surface, but the equipment cost and control cost increase , and when performing rotary marking, because the marking object is raised, the laser focus may exceed the adjustment range of the laser marking machine, resulting in marking failure; in addition, the marking range of the existing laser mar...
