Abstract

Изобретение относится к способу резки хрупких прозрачных неметаллических материалов, например стекла, лазерным лучом и может быть использовано в стекольной, электронной и других отраслях народною хозяйства. Сущность изобретения состоит в том, что резку хрупких прозрачных неметаллических материалов проводят путем воздействия на разрезаемый материал сфокусированным лазерным лучом или другим источником излучения с использованием отражающей излучение подложки, причем в разрезаемом материале создают два соосно фокусирующих излучения при многократном прохождении лазерного луча за счет двух вогнутых зеркал, расположенных асимметрично на противоположных сторонах материала. Расстояние между фокусами изменяют в зависимости от толщины разрезаемого материала. Нижнее и верхнее зеркала соединяют друг с другом через диэлектрический материал в единую систему посредством использования магнита или электромагнита. Нижнее и верхнее зеркала соединяют друг с другом в единую систему посредством использования магнита или электромагнита. Кроме этого, нижнее зеркало снабжено скользящей системой или роликами, позволяющими зеркалу при движении верхнего зеркала перемещаться соосно с ним. Изобретение позволяет во всем диапазоне толщин разрезаемого материала, например стекла толщиной 0,1-30 мм, получить более высокие точности реза до 50 мкм, более высокое качество (до 12 класса чистоты) разделяемых поверхностей на всех участках разрезаемого материала, как в массиве, так и на его краях.The invention relates to a method of cutting fragile transparent non-metallic materials, such as glass, laser beam and can be used in glass, electronic and other sectors of the national economy. The essence of the invention is that cutting brittle transparent non-metallic materials is carried out by exposing the material being cut with a focused laser beam or other radiation source using a substrate reflecting radiation, and in the material being cut two coaxially focusing radiation is created with repeated passage of the laser beam by two concave mirrors arranged asymmetrically on opposite sides of the material. The distance between the foci change depending on the thickness of the material being cut. The lower and upper mirrors are connected to each other through a dielectric material into a single system through the use of a magnet or an electromagnet. The lower and upper mirrors are connected to each other into a single system through the use of a magnet or an electromagnet. In addition, the lower mirror is equipped with a sliding system or rollers that allow the mirror to move coaxially with it when the upper mirror moves. The invention allows in the whole range of thickness of the material being cut, for example, glass with a thickness of 0.1-30 mm, to obtain higher cutting precisions up to 50 microns, higher quality (up to 12th grade of cleanliness) of the divided surfaces in all parts of the material being cut, both in the array and in and at its edges.
