Abstract

The invention relates to an automatic dust prevention method, belongs to the technical field of laser melting forming, and solves the problem that a laser window is easily polluted by smoke dust in the prior art. The method comprises the following steps: S1, debugging preparation: connecting a pipeline of an airflow assembly, and arranging a sensor and an observation camera; s2, an inert gas supply system is started, and a gas flow assembly is debugged; s3, a smoke generator is placed, and airflow is observed; s4, recording parameters, dismounting the sensor and observing the camera; and S5, controlling the airflow assembly according to the parameters recorded in the step S4 to realize automatic dust prevention of the laser window. According to the invention, the multi-point sensor and the observation camera are adopted to monitor the running state of the airflow generated by the automatic dustproof device, so that the automatic dustproof device of the laser window can generate three airflows, and the three airflows cooperate with one another to prevent smoke dust from polluting the laser window.
