Abstract

The invention relates to the technical field of laser processing, and discloses a sapphire laser slotting device and a slotting method thereof. The slotting device includes a laser, a reflector, a beam expander, a vibration mirror, a focusing mirror, a platform and a computer, and The sapphire sample is set on the platform, and the reflector, beam expander, vibrating mirror and focusing mirror are arranged above the sapphire sample to be processed in sequence from top to bottom. The center is located on the same straight line, the laser is located on one side of the reflector, and the computer is connected to the vibrating mirror; the invention adopts the continuous curve method, compared with the traditional filling scanning, the processed laser groove has better processing effect and less edge collapse The volume is small and the cross-section is smooth. In addition, according to the scanning trajectory of each layer, helical lines are generated for scanning. Such scanning trajectory can solve the phenomenon of poor processing of laser joints in conventional laser scanning, and can also avoid the jump problem caused by filling scanning. Precision.

Description

technical field [0001] The invention relates to the technical field of laser processing, and more specifically, relates to a sapphire laser slotting device and a slotting method thereof. Background technique [0002] Sapphire has the characteristics of scratch resistance, abrasion resistance and corrosion resistance. Compared with other glasses, the advantages have long been understood by many people. However, due to the price of the material itself and the difficulty of processing, it has been difficult to be widely used. At present, sapphire The cost of materials and the gradual decline, and the technology in the field of laser micromachining has also developed rapidly, and it has great market application prospects for sapphire cutting, drilling, and grooving. At present, sapphire is mainly processed by diamond-coated wire. Due to the high cost of diamond and the contact processing method, the diamond-coated wire is easily damaged after being used to a certain extent, whic...
