Description

technical field [0001] The present invention relates to the technical field of laser processing, in particular to a pulsed laser output synchronous closed-loop control system, method, terminal and medium. Background technique [0002] Pulsed laser refers to the light pulses emitted by lasers that work in pulse mode. Pulsed lasers need to be continuously supplied with energy by a laser pump source during operation, so that they can generate and output pulsed laser light for a long time. Due to its periodic working mode, short pulse duration, and low heat generation, pulsed laser has been widely used in various fields such as industrial production, scientific research, national defense construction, and medical beauty. [0003] In the field of industrial production, pulsed laser technology is widely used in laser cleaning, laser peening, laser drilling, laser welding, etc. For the technical application of pulsed laser, the main difficulties are as follows: First, because the...

Problems solved by technology

Generally, the laser peening control system can adopt the mode of independent control of the motion mechanism and the laser. The light output frequency of the laser must be strictly matched with the running speed of the motion actuator. When the motion actuator just moves to the target position, the laser just emits light, which requires repeated debugging. , not only wasting time and manpower, but also the laser point control accuracy is low, and the process control of laser shot peening impact is lacking

The second is the PLC-based laser output-execution mechanism motion coordinated control mode. Although the laser trigger time point can be accurately matched with the motion in place time point, due to the inherent scanning cycle of the PLC, the laser output frequency can only reach 1 -2Hz, the impact efficiency of laser shot peening is not high
