Embodiment Construction

[0014] The implementation of the optical power equalizer used in the multi-channel laser marking machine provided by the present invention will be described below with reference to the accompanying drawings. FIG. 1 is a schematic diagram of the structure and optical path of a four-channel laser scriber equipped with an optical power equalizer for a multi-channel laser scriber provided by the present invention. At present, the general-purpose four-way laser marking machine is composed of a beam splitter 1 with a reflectivity of 1 / 4 when the laser is incident at 28 and 45°, a spectroscopic plate 2 with a reflectance of 1 / 3 when incident at 45°, and a reflectance at incident at 45° Be 1 / 2 dichroic sheet 3, total reflection prism 4, condenser lens 24,25,26,27 constitute. Its working process is: laser device 28 sends out a beam of laser light, successively passes through beam splitter 1,2,3 and total reflection prism 4 to form four bundles of downward parallel laser beams, then con...

Abstract

The invention belongs to the optical technical field and relates to an optical power equalizer used for a multipath laser graver, which consists of a controller and a polarization controller, a polarizer, a light splitting plate and a photoelectrical detector inside the reflexion light path of the light splitting plate which are orderly arranged in the initial laser light path of the multipath laser graver, the polarization controller, an analyzer, the light splitting plate and the photoelectrical detector inside the reflexion light path of the light splitting plate which are orderly arranged under the multipath laser graver to score in each laser light path. The photoelectrical detectors in each laser light path are used for monitoring the light power of each laser light path and transferring a monitor signal to the controller. The controllers are arranged at the initial laser light path, and each polarization controller in a down actualizing graver light path sends different simulation control signals, which achieves the purpose of equalizing the multipath laser light power of the graver by adjusting the polarization state of the laser to be matched with the polarizer and the analyzer.

Description

technical field [0001] The invention belongs to the field of optical technology and relates to an optical power equalizer for a multi-channel laser marking machine. Background technique [0002] Multi-channel laser marking machines are widely used in laser marking, laser marking, and laser engraving. It is an important aspect of laser in industrial applications. It has a large proportion in the international laser industry and is on the rise. However, at present, the optical power of the multi-channel marking laser in the multi-channel laser marking machine is limited by the parameters of the splitting film in the multi-channel marking machine, and there is a large error in the optical power of each laser. Taking the four-way laser marking machine as an example, its working process is: a beam of laser light is emitted by the laser, passes through three beam splitters with different beam splitting ratios and a total reflection prism, and is divided into four beams of downward...
