Description

Technical Field

[0001] The utility model belongs to the technical field of 3D laser machines, and in particular relates to a 3D laser machine. Background Art

[0002] 3D laser machines are based on the mechanism of interaction between laser beams and materials. Generally, laser machining can be divided into two categories: laser thermal processing and photochemical reaction processing. Laser thermal processing refers to the use of the thermal effect generated by projecting a laser beam onto the surface of a material to complete the processing process, including laser welding, laser engraving and cutting, surface modification, laser marking, laser drilling and micromachining, etc. Photochemical reaction processing refers to the use of high-density laser high-energy photons to irradiate an object with a laser beam to initiate or control a photochemical reaction.

[0003] The existing 3D laser machine moves the laser processing position by the moving wheel at the bottom during use, moves the device to the processing position, and processes the material by the laser mechanism, but has the following defects:

[0004] (1) After the existing 3D laser machine moves to the processing position through the bottom moving wheel, each brake component at the bottom needs to be adjusted one by one to achieve the braking of the device position, effectively avoiding the position change of the laser machine. However, in the actual braking operation, each brake component needs to be adjusted one by one, resulting in inconvenient braking and time-consuming and labor-intensive problems;

[0005] (2) During the operation of existing 3D laser machines, the internal components of the device are prone to faults such as leakage and overheating, which cannot be discovered and stopped in time. As a result, when laser processing materials under fault conditions, it is easy to cause deviations in material processing accuracy. For this reason, we propose a 3D laser machine.
