Problems solved by technology

[0002] The material of the quartz glass tube and the quartz glass rod is a hard and fragile SiO with stable chemical properties. 2 The material is difficult to cut because of its high hardness and fragility. At present, it is mainly cut by dynamic glass knife or grinder. When the glass knife or grinding wheel directly contacts the quartz glass tube or quartz glass rod, it is easy to cause damage to the quartz glass tube. , the pass rate drops sharply, and the production efficiency is low

Abstract

The invention discloses a method for non-contact laser cutting of a quartz glass product and a device thereof. The method comprises the following steps: firstly firing the quartz glass product with a laser beam emitted by a laser generator to form a groove, and then cutting off by using a pneumatic unit. The device provided by the invention comprises a laser automatic cutting unit and the pneumatic unit. According to the invention, the product quality can be guaranteed, crevasses can be reduced, the consistency of the kerf and the kerf section can be guaranteed, waste is reduced, thus the operation is safe; and the laser cutting has noncontact with the quartz glass tube or quartz glass rod, thus the speed of drawing is raised, the production cost is reduced, the labor intensity is reduced, and the yield is raised.

Description

technical field [0001] The invention relates to a non-contact laser cutting method and device for quartz glass products, in particular to a method for cutting a quartz glass tube or a quartz glass rod by using laser technology without contacting a quartz glass tube or a quartz glass rod and its devices. Background technique [0002] The material of the quartz glass tube and the quartz glass rod is a hard and fragile SiO with stable chemical properties. 2 The material is difficult to cut because of its high hardness and fragility. At present, it is mainly cut by dynamic glass knife or grinder. When the glass knife or grinding wheel directly contacts the quartz glass tube or quartz glass rod, it is easy to cause damage to the quartz glass tube. , the pass rate has dropped significantly, and the production efficiency is low. Therefore, in order to improve output and quality, reduce energy consumption, reduce labor costs and reduce labor intensity, there is an urgent need for ...
