Description

Technical Field

[0001] The invention relates to the field of femtosecond laser processing equipment, and in particular to a laser processing device for a fused quartz micro-filtration plate. Background Art

[0002] The fused quartz microfiltration plate mainly separates impurities in the water by physical screening and utilizing the selectivity of pore size. The size of the micropores is usually between 0.1 and 10 microns, which can effectively remove suspended solids, turbid substances and microorganisms in the water. However, due to the hardness and brittleness of the quartz material, cracks will occur on the plate, so it is necessary to use laser to bridge the cracks. The existing laser processing device includes a carrier, a laser through-hole machine that can generate laser, a servo platform for fixing the workpiece to be processed and moving the workpiece to be processed, an imaging positioning system and an industrial control computer. The laser through-hole machine is arranged on the carrier, a bracket is fixedly arranged on the carrier, the imaging positioning system is arranged on the bracket, the servo platform is arranged on the carrier, and the industrial control computer is connected to the imaging positioning system. This type of processing device mainly realizes the movement of the workpiece by moving the servo platform. The laser emitter fills the cracks on the plate, but there are no protective components around the laser emitter. This will cause dust to splash into other cracks when the laser emitter generates a beam. When the laser emitter performs laser filling on this crack, particles will be embedded in the plate, affecting the quality of crack filling. Summary of the invention
