Laser rotating multiple focus coaxial vision system

摘要

The present invention relates to a rotating multifocal coaxial image surveillance type laser processing apparatus, and more particularly, a beam split mirror for separating a laser beam and an image signal between a light splitting prism and a condenser lens and coaxially behind the beam split mirror. Rotating multifocal coaxial laser processing device that obtains coaxial video signal in real time even with multi-view laser processing device using optical split prism by attaching video surveillance device and circular trajectory to target by equipping prism with rotating device It is about.;Rotating multifocal coaxial video surveillance laser processing apparatus of the present invention,;In the laser processing apparatus used for laser welding or cutting,;A collimating lens 2 for transmitting a laser beam emitted from the optical fiber 10;;A total reflection mirror (3) for reflecting the laser beam transmitted through the collimating lens (2);;A light splitting prism (5) for dividing the laser beam reflected through the total reflection mirror (3);;A prism rotating device (14) for rotating the light splitting prism (5);;A beam splitting mirror (4) positioned between the light splitting prism (5) and the condenser lens (8) to separate an image of the laser beam and the target (9);;It comprises an image optical system (6), an interference filter (13) and a laser light blocking filter (10), and installed on one side of the beam splitting mirror (4) to obtain a real-time processing state of the target (9) as an image signal in coaxial A CCD camera unit 7;;A condenser lens 8 for condensing the laser beam reflected through the beam splitting mirror 4;;It is installed between the beam splitting mirror 4 and the condenser lens 8, characterized in that it comprises a single wavelength illumination unit 11 for irradiating the illumination light to the target.;According to the present invention, a beam splitting mirror separating a laser light and an image signal between a light splitting prism and a condenser lens may be mounted on one side of the beam splitting mirror to simultaneously perform real-time monitoring and autofocus control of rotating multifocal laser processing. By attaching a coaxial video monitoring device to obtain a coaxial video signal in real time from a multifocal laser processing device using a prism, the operator can easily and in real time recognize or monitor the processing status of the workpiece, thereby improving the quality and productivity of the workpiece. Not only does it greatly improve the effect, but also in the field of laser welding and cutting, as well as its application to the processing device using a laser beam is great.;Multifocal laser, laser beam transmission monitoring, video surveillance, laser processing head, processing status monitoring, auto focusing device, light splitting prism, prism rotating device.
