Abstract
Description
Technical Field
[0001] This utility model relates to the field of laser die-cutting technology, and in particular to an integrated module of a high-power laser and a high-speed galvanometer. Background Technology
[0002] Laser die-cutting technology, as an advanced processing method, has been widely used in various industrial fields such as consumer electronics, new energy vehicles, packaging and printing, and medical products. With the increasing demands for processing precision, efficiency, and automation, laser processing systems combining high-power lasers and high-speed galvanometers have become the mainstream trend.
[0003] In existing technical solutions, such as Figure 3 As shown, high-power lasers and high-speed galvanometers are typically mounted as two separate components on the frame or worktable of laser processing equipment. The laser beam emitted by the laser needs to pass through a series of reflecting mirrors independently mounted on the equipment platform, undergoing long-distance and multiple optical path deflections before finally entering the light inlet of the high-speed galvanometer.
[0004] This traditional discrete layout is inefficient in terms of space utilization. The laser, galvanometer, and the optical path system connecting them all require separate planar installation space on the equipment, resulting in a loose overall layout and a large footprint, which is not conducive to achieving miniaturization and compact design of the equipment.
[0005] Secondly, because the optical path system involves multiple discrete components, the installation and debugging process is complex. Optical path calibration can only be performed after all relevant components of the entire device are installed. This means that the optical path testing phase cannot proceed in parallel with the mechanical assembly phase, severely restricting the overall installation and debugging efficiency of the project.

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.
[0028] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used in this specification is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.
[0029] like Figure 1 and Figure 2 This application provides an integrated module of a high-power laser 2 and a high-speed galvanometer 3, including a housing 1 and a high-power laser 2 and a high-speed galvanometer 3 disposed therein. A first refractor assembly 4 and a second refractor assembly 5 are disposed opposite to each other on the housing 1. The high-power laser 2 and the high-speed galvanometer 3 are arranged side by side in the vertical direction in the housing 1. The first refractor assembly 4 and the second refractor assembly 5 are respectively disposed corresponding to the high-power laser 2 and the high-speed galvanometer 3. A third light-emitting hole 111 is opened on the housing 1 corresponding to the high-speed galvanometer 3.
[0030] The high-power laser 2 and the high-speed galvanometer 3 are arranged in a vertically stacked layout, which greatly saves the space occupied by the equipment in the horizontal direction compared with the traditional horizontally distributed installation, and is conducive to a more optimized spatial layout of the entire equipment.
[0031] The high-power laser 2 and the high-speed galvanometer 3, together with the first refractive mirror assembly 4 and the second refractive mirror assembly 5, constitute a complete optical path transmission system.
[0032] Specifically, the output port of the high-power laser 2 is positioned opposite to the input port of the first refractive mirror assembly 4, from which the laser beam is emitted. The output port of the first refractive mirror assembly 4 is positioned opposite to the input port of the second refractive mirror assembly 5, completing the first bend of the laser beam. The output port of the second refractive mirror assembly 5 is positioned opposite to the input port of the high-speed galvanometer 3, precisely guiding the laser beam into the galvanometer system. The output port of the high-speed galvanometer 3 is positioned towards the third output aperture 111, and the laser beam, scanned and controlled by the high-speed galvanometer 3, is emitted from the third output aperture 111, ultimately acting on the workpiece. This integrated optical path system has a compact structure and stable optical path, avoiding calibration difficulties and optical path misalignment problems that may arise from the dispersed installation of components.
[0033] In this embodiment, the housing 1 includes a galvanometer base plate 11 and a laser base plate 12 arranged in parallel. The laser base plate 12 is fixedly mounted above the galvanometer base plate 11 by a plurality of fixed connecting rods 17 arranged perpendicular to it, forming a stable support frame.
[0034] The high-speed galvanometer 3 is mounted on the galvanometer base plate 11, the high-power laser 2 is mounted on the laser base plate 12, and the third light-emitting hole 111 is mounted on the galvanometer base plate 11 and faces the light-emitting port of the high-speed galvanometer 3 to ensure that the processing laser can be emitted without obstruction.
[0035] Furthermore, a front end plate 13 and a rear end plate 14 are respectively vertically arranged at both ends of the length of the galvanometer base plate 11 and the laser base plate 12. The light output port of the high-power laser 2 and the light input port of the high-speed galvanometer 3 are both arranged facing the rear end plate 14, so that the optical path system is concentrated at the rear end of the module.
[0036] The first refractive mirror assembly 4 and the second refractive mirror assembly 5 are both disposed on the rear end cover plate 14. Specifically, the first refractive mirror assembly 4 and the second refractive mirror assembly 5 are both disposed on the outer side of the rear end cover plate 14. In order to facilitate the laser beam passing through the rear end cover plate 14, a first light exit hole 141 and a second light exit hole 142 are respectively provided on the rear end cover plate 14 corresponding to the first refractive mirror assembly 4 and the second refractive mirror assembly 5.
[0037] To protect the delicate optical components and prevent dust, an optical path cover 18 is provided on the outside of the rear end cover 14, which encloses the first refractive mirror assembly 4 and the second refractive mirror assembly 5. This ensures that the optical path components operate in a clean environment, reduces maintenance frequency, and allows for immediate sealing after optical path debugging, making it convenient and quick.
[0038] To facilitate optical path calibration, a fine-tuning device 6 is provided on the laser base plate 12 corresponding to the high-power laser 2. The fine-tuning device 6 can finely adjust the output angle of the laser during the debugging process to ensure that the optical path is precisely aligned with the first refractive mirror assembly 4, so that the core optical path can be calibrated during the independent testing phase of the module.
[0039] In this embodiment, the housing 1 also includes a top cover plate 15 and side cover plates 16 disposed opposite to it on both sides; the housing 1 is enclosed by the galvanometer base plate 11, the two side cover plates 16, the top cover plate 15, the front end sealing plate 13 and the rear end sealing plate 14; the inner cavity of the housing 1 is divided into an upper cavity 191 and a lower cavity 192 by the laser base plate 12, and the high-power laser 2 and the high-speed galvanometer 3 are located in the upper cavity 191 and the lower cavity 192, respectively.
[0040] The housing 1 adopts a modular packaging structure, which facilitates independent testing of the optical path and allows for parallel assembly with the whole machine, thus improving efficiency.
[0041] A power signal interface 143 is provided on the rear cover plate 14 for connecting external power and control signal lines. When maintenance is required, the connection can be quickly disconnected and the entire integrated module can be removed from the device, greatly simplifying the maintenance process.
[0042] The high-power laser 2 and high-speed galvanometer 3 integrated module disclosed in this application vertically stacks and integrates the high-power laser 2 and high-speed galvanometer 3 through a modular housing 1 structure, effectively utilizing three-dimensional space and making the overall equipment layout more compact.
