Vacuum system for laser processing

Abstract

The invention discloses a vacuum system for laser processing, aiming to provide a technical proposal for solving the problem that a plurality of metallic materials can not be processed by laser in the unprotected condition: the system mainly comprises a vacuum tank, a vacuum pumping and gas filling component matched with the vacuum tank and a computer control module (1) used for controlling and connecting the vacuum tank and the component. The vacuum system can realize the laser processing operation on two-dimensional surface in vacuum environment or shielding gas condition and has the advantages of low laser absorptivity, best transmissivity and long service life by adopting the laser window with zinc selenide lens, improved efficiency of the vacuum pumping, enhanced efficiency and quality of the laser processing by adopting the Root's vacuum pump and rotary mechanical pump, convenient operation, high reliability and favorable guarantee of laser processing quality by adopting the vacuum sensor and the vacuum manometer to read the vacuum degree of the vacuum tank, convenient operation, friendly interface, enhanced automation degree, performance stability and reliability of laser processing, thus being also convenient for integration and control with the other systems by adopting the computer control management.

Description

Technical field: [0001] The invention relates to a vacuum system used in laser processing equipment to isolate air, create a vacuum environment or a protective gas environment, and ensure the processing quality of processed parts, in particular to a vacuum system for laser processing. Background technique: [0002] Laser is one of the great inventions of natural science in the 20th century.
