Problems solved by technology

[0003] The existing carbon dioxide laser power supply can drive the carbon dioxide laser, but when the carbon dioxide laser leaks due to aging and failure and discharges the machine tool system equipped with the carbon dioxide laser, it does not perform any operation, thus continuing to work in an abnormal state. Under load, it often leads to damage to the power supply itself
In addition, the existing carbon dioxide laser power supply has continuous discharge when the carbon dioxide laser leaks, and the strong electromagnetic radiation generated by this continuous discharge will cause damage to other electrical equipment in the machine tool system.
At the same time, the continuous electric spark generated by the discharge may cause the flammable parts of the equipment in the machine tool system to catch fire, resulting in unpredictable losses

Abstract

The invention provides a carbon dioxide laser power supply which comprises a power supply unit for transforming power distribution of a factory so as to supply power to a carbon dioxide laser, a laser fault detecting unit for detecting faults of the carbon dioxide laser and a control processing unit. When the laser fault detecting unit detects the faults of the carbon dioxide laser, output of the carbon dioxide laser power supply is cut off according to a detecting result of the laser fault detecting unit.

Description

technical field [0001] The invention relates to the field of power supplies, in particular to carbon dioxide laser power supplies. Background technique [0002] At present, carbon dioxide lasers have been widely used in laser marking, laser cutting, laser drilling, laser surgery and other fields. Therefore, the carbon dioxide laser and its driving power are required to have the characteristics of long life, high stability, strong safety, and easy troubleshooting. [0003] The existing carbon dioxide laser power supply can drive the carbon dioxide laser, but when the carbon dioxide laser leaks due to aging and failure and discharges the machine tool system equipped with the carbon dioxide laser, it does not perform any operation, thus continuing to work in an abnormal state. Under load, it often leads to damage to the power supply itself. In addition, the existing carbon dioxide laser power supply has continuous discharge when the carbon dioxide laser leaks, and the strong ...
