Description

Technical Field

[0001] This utility model relates to the technical field of laser welding processing, specifically to an adjustment device and a laser welding head for simultaneous observation of laser welding with a microscope. Background Technology

[0002] In traditional laser welding, the welding process can only be observed with the naked eye. Some special laser welding points are extremely small, making them difficult to observe clearly with the naked eye, thus hindering production and causing significant problems. To address this issue, laser welding equipment with microscopic optical instruments, such as laser welding machines, has been invented. These machines rely on microscopes for positioning and precision welding. However, the single-view observation mode of microscopes has limitations, easily causing eye fatigue for welding machine users and increasing their risk of occupational diseases (cervical spondylosis). The reflector mount, a crucial component of the microscopic optical instrument, reflects the image captured by the camera onto the microscope. Users then observe the image to perform subsequent welding operations. However, existing reflector mounts are mostly fixed and non-adjustable. When adjusting the center point of the welding position, it is necessary to move the workpiece for repositioning, making it impossible to quickly locate the desired welding position by adjusting the image, thus affecting subsequent welding efficiency. Therefore, there is an urgent need for a non-field-of-view optical imaging technology to achieve simultaneous microscopic observation, coaxial adjustment, and clear confocal images.
