Abstract

The invention provides a delay power supply circuit suitable for a fiber laser etching system. The circuit comprises a laser generator, a galvanometer scanning head for controlling a laser path, a laser control card for controlling the laser generator and the galvanometer scanning head, and a four-in-one switching power supply for controlling a power-on time sequence and a power-off time sequence, wherein the four-in-one switching power supply is electrically connected with a 220 V alternating current voltage, and the galvanometer scanning head, the laser generator and the laser control card are all electrically connected with the four-in-one switching power supply. The invention further provides a delay method suitable for the fiber laser etching system. According to the circuit and the method, a problem of safety risk caused by uncontrolled light emission of a laser is solved.

Description

technical field [0001] The invention relates to the technical field of laser marking, in particular to a delay power supply circuit and a delay method suitable for an optical fiber laser engraving system. Background technique [0002] Laser engraving technology refers to a marking method in which a high-energy-density laser beam is partially irradiated on a product under the control of a computer to instantly melt or vaporize the surface of the product, thereby leaving a permanent mark. Laser engraving has the advantages of wide engraving content, high efficiency, clear engraving, and cleanliness. [0003] The basic components of laser engraving equipment include control system and laser system. The control system is generally a control board, and the laser is controlled by the control board to adjust laser power and frequency, laser switch, etc. However, at the moment of power-on and power-off of the whole system, because the control board needs to start reset and other pr...
