Problems solved by technology
[0003] At present, the existing laser cutting equipment and laser welding equipment are two independent systems. Therefore, when laser cutting and laser welding are required in the processing process, it is necessary to purchase laser cutting equipment and laser welding equipment at the same time. The cost is relatively high, and the process is relatively cumbersome and complicated

Abstract
The invention discloses an optical device for realizing switching between laser cutting and welding applications, which includes a case, a laser light source located in the case and used for emitting laser beams, and also includes: a laser light source arranged on the transmission path of the laser beam for controlling the laser beam A focusing mirror for coupling; an energy-transmitting optical fiber arranged at the light outlet of the focusing mirror; a diverging mirror that is movably installed in the chassis, and the diverging mirror is used to move into the optical path formed by the laser light source, focusing mirror and energy-transmitting optical fiber Diffusion of the laser beam while in the middle allows the laser beam to be used for laser welding and for use in laser cutting when removed from the optical path. The above-mentioned technical solution disclosed in the present application can perform both laser welding and laser cutting, and can realize flexible conversion between laser welding and laser cutting by adjusting the position of the diverging mirror, therefore, equipment costs can be reduced and the process can be simplified process.
Description
technical field [0001] The invention relates to the technical field of laser processing, and more specifically relates to an optical device for switching between laser cutting and welding applications. Background technique [0002] Laser processing technology is a processing technology that uses the characteristics of the interaction between laser beams and substances to cut, weld, surface treat, drill and micro-process materials. As an advanced manufacturing technology, it has been widely used in automobile manufacturing, aerospace , instrumentation, industrial processing and many other fields. Among them, laser cutting and laser welding technology are important applications of laser processing technology. These two technologies complement each other and are inseparable in the industrial processing process. [0003] At present, the existing laser cutting equipment and laser welding equipment are two independent systems. Therefore, when laser cutting and laser welding are r...
