Laser marking machine capable of positioning focus rapidly and focus positioning method

Abstract

The invention discloses a laser marking machine capable of positioning the focus rapidly. The laser marking machine comprises a pedestal and a laser, a support column is arranged on the pedestal, an up-down slide block is arranged on the support column, a laser power supply is also arranged on the pedestal, the laser is connected to a computer control system via a data line, a certain distance is kept between a workpiece and the laser, and the head portion of the laser is provided with a visual light source A and a visual light source B. The laser marking machine capable of positioning the focus rapidly and a focus positioning method enable that workers who user the laser can adjust the laser focus conveniently and simply when the workpiece is replaced, the laser focus and focal length can be accurately determined via light visible to naked eyes, and laser deviation caused by inaccuracy of manual laser focal length adjustment can be reduced.

Description

technical field [0001] The invention relates to the field of laser equipment, in particular to a laser marking machine with rapid focus positioning and a focus positioning method. Background technique [0002] Existing laser equipment includes laser marking machine, laser cutting machine, laser welding, laser drilling machine, laser coating equipment, etc. The principle is to use the laser beam to interact with the workpiece to cut and weld the material of the workpiece , surface treatment, drilling and micromachining and laser heat treatment to complete industrial applications. [0003] It is necessary to maintain a certain focal length in the laser processing of objects. When working, it is necessary to ensure that the laser focus is at the working position. The accuracy of the laser focal length is very important. The error of the focal length may cause the loss of the workpiece. The existing laser focal length generally uses manual rotation. Turn and adjust the laser. A...

[0003] It is necessary to maintain a certain focal length in the laser processing of objects. When working, it is necessary to ensure that the laser focus is at the working position. The accuracy of the laser focal length is very important. The error of the focal length may cause the loss of the workpiece. The existing laser focal length generally uses manual rotation. Turn and adjust the laser. After the work is completed for one workpiece, the height between the workpiece object and the laser needs to be repositioned for another workpiece, which increases the difficulty for the staff.
