The invention provides a dual-optical-path
laser marking apparatus and a making method thereof. The dual-optical-path
laser marking apparatus comprises a rack
assembly, a camera
assembly, a lifting platform mechanism, a jig
assembly, a mirror assembly and an
optics and
galvanometer system. The camera assembly is used for carrying out
bias detection on optical paths. The jig assembly is fixed to the lifting platform mechanism. The
optics and
galvanometer system comprises a platform, an
optical fiber nanosecond laser device and a
picosecond laser device, an
optical path system, a
galvanometer and a field lens, wherein the
optical fiber nanosecond laser device and the
picosecond laser device are fixed to the platform, the
optical path system is arranged in front of the
optical fiber nanosecond laser device and the
picosecond laser device, the galvanometer is connected with the
optical path system, and the field lens is located below the galvanometer. Lasers respectively emitted by the optical
fiber nanosecond laser device and the
picosecond laser device pass through the optical
path system, then enter the galvanometer in an incidence manner, and carry out
laser processing on productsthrough the field lens. According to the dual-optical-path laser marking apparatus, the
picosecond laser device is used for carrying out high-speed outline scanning on products, the
nanosecond laser device is used for outline filling, the
processing quality is effectively guaranteed, and the production efficiency is improved at the same time.
