Embodiment Construction

[0026] The novel closed-loop laser power automatic adjustment system of the exemplary embodiment of the present invention will be described in detail below with reference to the accompanying drawings.

[0027] figure 1 A schematic flowchart of the principle of the new closed-loop laser power automatic adjustment system according to an example embodiment of the present invention is shown.

[0028] Such as figure 1 As shown, when the laser equipment is running, the CNC system 1 of the equipment controls the laser power supply 3 through the control signal through the data line 2. After receiving the signal from the CNC system 1 of the equipment, the laser power supply 3 adjusts itself, and then adjusts the adjusted The voltage and current are sent to the laser 5 through the wire 4 to adjust the laser power output by the laser 5. When the laser beam 6 output by the laser 5 reaches the beam splitter 7, the beam splitter 7 reflects a part of the laser beam 6 according to a certain ...

Abstract

The invention provides a novel closed-loop laser power automatic adjusting system which mainly comprises a numerical control system, a laser power supply, a laser and a laser power sensing feedback device, wherein the laser power sensing feedback device is mainly composed of a spectroscope, a sensor and a sensor signal processor. The novel closed-loop laser power automatic adjusting system is mainly applied to laser power adjustment of numerical control laser equipment. The operation of the laser equipment is monitored in real time, and the output laser power of the laser is automatically adjusted to adapt to different working conditions. The sensor receives a part of light beam irradiated by the spectroscope according to the proportion, and different light beam energy is converted into electric signals to be transmitted to the sensor signal processor, and then is processed by the sensor signal processor according to the signal difference and then is fed back to the numerical control system. The numerical control system then adjust the output laser power of the laser.

Description

technical field [0001] The invention relates to optical power adjustment, in particular to closed-loop adjustment of laser power. Background technique [0002] The traditional optical power adjustment systems currently on the market are all open-loop adjustments, which only use the numerical control system of the equipment to adjust, and it can only be set before the equipment is running and then controlled by the numerical control system to adjust the optical power. The adjustment is too simple and cannot adapt to the change of working conditions during the operation of the equipment, which reduces the application range and performance of the equipment. [0003] The optical power adjustment of the traditional structure mainly has the following defects: [0004] (1) It cannot be adjusted at any time during the operation of the equipment [0005] (2) The adjustment is too simple to adapt to the changes in the working conditions of the equipment [0006] (3) The adjustment ...
