Abstract

The invention relates to an electron beam forming and manufacturing visual monitoring system preventing metal vapor pollution, and belongs to the technical field of electron beam forming and manufacturing monitoring. The monitoring system comprises a metal vapor anti-pollution system, an optical observation system and a camera cooling sleeve; a motor is used to drive a group of adsorption fan blades to rotate at high speed to effectively adsorb the metal vapor generated during an electron beam processing process, so as to prevent the metal vapor from contaminating optical components in the visual monitoring system, thereby realizing the stable and reliable monitoring of the electron beam processing process. By controlling the exposure trigger time of an industrial camera in the visual monitoring system, synchronous imaging is performed when two adjacent fan blades successively pass through an optical axis of a lens, so as to prevent the fan blades from blocking a light path. The monitoring system is simple in structure and low in cost, and is suitable for performing effective visual monitoring on any processing process with stronger metal vapor pollution.

Description

technical field [0001] The invention relates to a visual monitoring system for electron beam forming manufacturing to prevent metal vapor pollution, and belongs to the technical field of electron beam forming manufacturing monitoring. Background technique [0002] Process repeatability and quality consistency are the key to measuring this manufacturing technology, which is especially important in aerospace and medical fields. However, the environmental parameters in the electron beam forming manufacturing process are variable, such as the instability of equipment parameters, heat accumulation during the forming process, and changes in the composition of metal materials. This makes it impossible to achieve continuous stability of the forming process only relying on traditional techniques. In recent years, more and more electron beam forming manufacturers have added process monitoring technology to their equipment, the most of which is visual monitoring technology. [0003] ...
