Problems solved by technology

For example, the strengthening process after glass welding often breaks due to the internal stress accumulated in the material by glass welding, which will also affect the appearance of the glass welding interface. Therefore, it is extremely urgent to develop a complete set of systematic process flow with important

Abstract

The invention discloses a system precision processing method of a fragile transparent special-shaped 3D structure. The system precision processing method comprises the following steps of building a laser welding platform of the special-shaped 3D structure, wherein the platform comprises a laser, a laser path, a coaxial vision system, a paraxial vision system, a welding head, a clamp, a horizontalwelding bracket and a movement platform; clamping a sample by the clamp; mounting the clamp after clamping the sample to the movement platform, and adjusting the clamp by the coaxial vision system and the horizontal adjusting bracket; and grabbing a welding profile by the paraxial vision system to perform profile positioning and processing path planning; generating laser by the laser, and focusing the laser on a welding interface to be welded through the laser path and the welding head, and moving the movement platform according to the positioned profile and the planned processing path untilfinishing the welding; placing a welded sample in an annealing furnace, and annealing according to a temperature curve of heating, constant annealing temperature and cooling; and placing the annealedwelded sample in a reinforcing furnace to be reinforced.

Description

technical field [0001] The invention belongs to the technical field of laser welding, and relates to the application of laser to glass and other brittle transparent materials, in particular to the processing of special-shaped 3D structures of brittle transparent materials, specifically a systematic precision processing method for special-shaped 3D structures of brittle transparent materials. Background technique [0002] There have always been many difficulties and problems in the processing of brittle transparent materials (such as glass, sapphire, diamond, etc.) Transmittance issues, etc. Traditional CNC machine tool processing will bring large residual stress to the brittle material 3D structure processing parts, which is easy to damage the micro structure, and will inevitably produce chamfers and rounded corners in the bending of the structure; and through the traditional bonding and molding Glass processing technology also has deficiencies in precision and strength. ...
