Laser cutting device and light splitting assembly thereof

Abstract

The invention discloses a laser cutting device and a light splitting assembly thereof. The light splitting assembly comprises a bracket, a reflecting mirror and a light splitting mirror, wherein the reflecting mirror and the light splitting mirror are parallel with each other and are arranged at intervals, and the light splitting mirror is arranged on one side, provided with a reflecting face, of the reflecting mirror. When laser beams illuminate the light splitting mirror in a preset angle, partial lights penetrate through the light splitting mirror, and the other lights are reflected to the reflecting mirror; after the lights are repeatedly reflected between the light splitting mirror and the reflecting mirror, the lights penetrating through the light splitting mirror form multiple groups of parallel emergent lights; the light splitting assembly can split the laser beams incident along the preset angle into multiple groups of parallel beams, and the energies of the beams are distributed according to a specific proportion, so that the energy distribution of light spots is more reasonable. Thus, when the laser cutting device is used for cutting, the light spots with the proper energies can be selected according to the requirements, and then the cutting yield is improved.

Description

technical field [0001] The invention relates to laser application technology, in particular to a laser cutting device and a light splitting component thereof. Background technique [0002] Traditional glass cutting adopts mechanical methods. With the continuous increase of market demand, the manufacturing industry has higher and higher requirements for production capacity, yield and glass quality. Mechanical methods are no longer suitable for the current process requirements. Laser cutting glass does not produce micro-cracks, which greatly improves the yield rate and saves the subsequent grinding process. Laser cutting not only improves production capacity, but also increases production efficiency. Therefore, laser glass cutting technology has become the future development direction, and will completely replace the existing mechanical cutting process in the near future. [0003] With the continuous development of the industry, the quality of glass cutting is also constantl...

AI Technical Summary

Problems solved by technology

However, in the traditional laser cutting device, when the power is fixed, the power and spot size of the laser beam are fixed, which makes it inconvenient to adjust the energy of the laser beam

When cutting, if the energy of the laser beam is too large, it may cause cracks in the cutting part, resulting in a decrease in product yield
