Abstract

The invention provides a double-focusing device of a light splitting mechanism of a laser drilling machine, and relates to the field of laser beam processing. The device is connected with a laser device, a multi-prism light splitting system, a drilling head and a paper advance mechanism for driving tipping paper to continuously move, and comprises a one-stage lens cone, a first focusing mirror, a two-stage lens cone, a second focusing mirror, a controller, an air pressure sensor, an air feed pipe and the like. The device can ensure that the energy of the laser beam subjected to light splitting is consistent, efficiently solves the problem that the drilling effect is inconsistent, controls the drilling effect, bore diameters and air permeability of tipping paper conveniently in the practical production, improves the drilling uniformity of the tipping paper, increases the drilling density, and efficiently improves the air permeability and stability of the tipping paper subjected to laser drilling.

Description

technical field [0001] The invention relates to the field of laser beam processing, in particular to a focusing device of a light splitting mechanism on a laser drilling machine. Background technique [0002] With the development of modern science and technology, laser generators have been used in more and more industries. Among them, laser drilling machines are widely used and promoted due to their inherent advantages of fast speed, low consumption and environmental protection. At present, the laser drilling machine is widely used in the field of laser processing. The high-energy-density laser is used to partially irradiate the workpiece to vaporize the surface material of the workpiece, thereby forming micropores on the surface of the workpiece. [0003] Compared with electrostatic perforation, mechanical perforation and other technologies, laser perforated tipping paper has incomparable advantages over other perforated perforated tipping papers, mainly in the following a...
