Description

Technical Field

[0001] This utility model belongs to the field of laser processing equipment technology, specifically relating to a laser processing galvanometer with supplementary lighting function that can measure temperature and distance. Background Technology

[0002] Lasers possess unique advantages such as high energy density, good directionality, and easy beam control, bringing revolutionary changes to processing technology. Laser processing equipment uses a precisely focused laser beam to cause the workpiece surface material to absorb high energy instantaneously, resulting in physical changes such as melting, vaporization, or sublimation, leaving permanent marks, cutting, and welding on the surface material.

[0003] Traditional galvanometers often rely on natural light for illumination when processing objects. The illumination effect comes from outside the galvanometer and is greatly affected by external factors and interference. It is difficult to provide a continuous, stable, and sufficient light source, which limits the improvement of the galvanometer's function.

[0004] Traditional laser galvanometers rely on a rotating lead screw for positioning, controlling the laser focusing distance and depth. This requires manual intervention. Pre-setting the laser focusing and depth before processing is difficult, and human factors make it hard to guarantee the accuracy and consistency of the focusing distance and depth. Furthermore, manual intervention is cumbersome, resulting in low automation and labor efficiency, and difficulty in ensuring consistent precision.

[0005] Furthermore, laser galvanometers require advance estimation of the processing effect on the object being processed and the processing of materials with temperature requirements. Predictive testing is conducted on different power equipment to determine the appropriate laser power, processing time, and processing frequency to determine the implementation plan. Temperature matching requires manual intervention, necessitating the determination of the extreme temperatures of different power equipment and the extreme temperatures the object can withstand before processing. This necessitates contact measurement and is a cumbersome procedure. Moreover, temperature changes are difficult to control due to the influence of time and operating conditions.
