Description

Technical Field

[0001] This utility model relates to the field of laser scanning galvanometer technology, and in particular to a laser scanning galvanometer that facilitates heat dissipation. Background Technology

[0002] A laser scanning galvanometer, also known as a laser mirror, is a precision optical component widely used in laser processing, laser display, and laser medical applications. It consists of an XY optical scanning head, an electronic drive amplifier, and optical reflectors. The XY optical scanning head typically contains two mutually perpendicular scanning motors, each driving a reflector to rotate, thereby deflecting the laser beam in the X and Y axes.

[0003] During operation, the motor and circuitry of the galvanometer generate heat. If the heat cannot be dissipated in time, it will cause the motor to overheat and affect its working efficiency. Currently, the heat dissipation methods for galvanometers include finned cooling or water cooling. For water cooling, please refer to the high-power laser galvanometer cooling structure disclosed in Chinese Patent Announcement "CN216680797U".

[0004] However, water cooling faces the challenge of condensation, and traditional finned heat dissipation solutions usually only have fins on the outer wall of the galvanometer housing. This heat dissipation design has a limited heat dissipation area and low heat dissipation efficiency.

[0005] Based on this, in order to solve the above problems, we propose a laser scanning galvanometer that facilitates heat dissipation. Summary of the Invention

[0006] The purpose of this invention is to address the shortcomings of existing technologies, such as the fact that traditional finned heat dissipation solutions typically only have fins on the outer wall of the galvanometer housing, resulting in limited heat dissipation area. This invention proposes a laser scanning galvanometer that facilitates heat dissipation.

[0007] To achieve the above objectives, the present invention adopts the following technical solution:

[0008] Design a laser scanning galvanometer that facilitates heat dissipation, including a galvanometer mount for mounting lens modules, an upper shell fixedly mounted above the galvanometer mount, and a through opening on the end face of the upper shell;

[0009] A heat-conducting component is detachably connected inside the through-hole, and a fan assembly is rotatably connected to the top of the upper shell, the fan assembly covering one end opening of the heat-conducting component.

[0010] Furthermore, the heat-conducting component includes a heat-conducting pipe, with a plurality of outer fins spaced apart on the outer side of the heat-conducting pipe, and a plurality of inner fins inside the heat-conducting pipe.

[0011] Furthermore, the outer fins are arranged in a ring-shaped structure, and the inner fins are arranged in a straight line, wherein the extending direction of the inner fins is perpendicular to the end face of the outer fins.

[0012] Furthermore, one end of the heat pipe is formed with a mounting plate, and the other end is movably connected to a connecting plate. The connecting plate abuts against the end face of the upper shell and is fixedly connected to the heat pipe by fasteners.

[0013] Furthermore, the fan assembly includes a frame and a fan mounted in the frame, with brackets fixedly mounted on both sides of the frame, and a connecting seat fixedly mounted on the top of the upper shell, the brackets and the connecting seat being rotatably connected.

[0014] Furthermore, a limiting seat is formed at the end of the bracket near the connecting seat, and two notches are opened on the outer periphery of the limiting seat. A ball-head plug is fixedly installed on the end face of the connecting seat, and the telescopic end of the ball-head plug engages with the notches.

[0015] The present invention proposes a laser scanning galvanometer that facilitates heat dissipation. The advantages are as follows: the present invention uses a heat pipe inserted inside the upper shell to facilitate heat dissipation of the entire galvanometer in cooperation with the fan assembly. At the same time, since the two ends of the heat pipe 31 are detachably connected to the upper shell and can be sealed, the heat dissipation capacity is improved while the possibility of dust entering is reduced, thus optimizing the heat dissipation efficiency of the existing galvanometer.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0022] Reference Figure 1-4 As one embodiment of this utility model, a laser scanning galvanometer with convenient heat dissipation is disclosed, including a galvanometer mount 1 for mounting a lens module 10. Of course, the galvanometer mount 1 has a mounting cavity inside. The lens module 10 includes an X-axis lens and a motor, as well as a Y-axis lens and a motor. When light enters through the light inlet of the galvanometer mount 1, the light is emitted from the lens at the bottom of the galvanometer mount 1 through the X-axis lens and the Y-axis lens. This application does not make any changes to this part of the structure, so those skilled in the art can use existing technology for this part of the structure.

[0023] Furthermore, in this embodiment, an upper shell 2 is fixedly installed above the galvanometer base 1. The upper shell 2 is connected to the upper part of the galvanometer base 1 for connecting signal lines and heat conduction. A through-hole 20 is opened on the end face of the upper shell 2.

[0024] The heat-conducting component 3 is detachably connected to the inside of the through-hole 20, and a fan component 4 is rotatably connected to the top of the upper shell 2. The fan component 4 can cover one end opening of the heat-conducting component 3.

[0025] In some embodiments, the heat-conducting component 3 of this utility model includes a heat-conducting pipe 31, which can be a copper pipe. A plurality of outer fins 32 are distributed at intervals on the outer side of the heat-conducting pipe 31, and a plurality of inner fins 33 are provided inside the heat-conducting pipe 31. The outer fins 32 are used to transfer the heat in the entire upper shell 2 to the heat-conducting pipe 31, and then discharge it outward through the inner fins 33 inside the heat-conducting pipe 31. Since the heat-conducting pipe 31 of this application adopts a design with open ends, it can ensure stable heat transfer and improve the heat dissipation capacity of the upper part of the galvanometer mount 1.

[0026] Based on the above embodiments, in this utility model, the outer fins 32 are distributed in a ring structure, and the inner fins 33 are distributed in a straight line, wherein the extending direction of the inner fins 33 is perpendicular to the end face of the outer fins 32.

[0027] Furthermore, in this embodiment, one end of the heat pipe 31 is formed with a mounting plate 34, and the other end is movably connected to a connecting plate 35. The connecting plate 35 abuts against the end face of the upper shell 2 and is fixedly connected to the heat pipe 31 by fasteners.

[0028] Specifically, in this embodiment, when the heat pipe 31 needs to be installed, one end of the heat pipe 31 is first inserted into the inside of the through-hole 20 until the mounting plate 34 touches the side of the upper shell 2. At this time, the connecting plate 35 can be sleeved on the other end of the heat pipe 31. The mounting plate 34 is fixed to the upper shell 2 with bolts, and the connecting plate 35 is fixed to the heat pipe 31 with bolts. At this time, both ends of the heat pipe 31 and both sides of the upper shell 2 are sealed, which can reduce the possibility of dust entering. Of course, a sealing gasket can also be placed between the mounting plate 34 and the connecting plate 35 and the upper shell 2 to further improve the sealing of the connection.

[0029] Based on the above embodiments, the fan assembly 4 in this embodiment includes a frame 41 and a fan 42 installed in the frame 41. The fan 42 includes a motor fixed on the frame 41 and blades connected to the motor shaft. Brackets 43 are fixedly installed on both sides of the frame 41. A connecting seat 21 is fixedly installed on the top of the upper shell 2. The brackets 43 and the connecting seat 21 are rotatably connected.

[0030] Of course, in order to lock and fix the rotation position of the bracket 43, in this embodiment, the end of the bracket 43 near the connecting seat 21 is formed with a limiting seat 44. Two notches 45 are opened on the outer periphery of the limiting seat 44. A ball head plug 46 is fixedly installed on the end face of the connecting seat 21. The telescopic end of the ball head plug 46 engages with the notch 45.

[0031] During the heat dissipation process, the entire fan 42 can be rotated to face the end of the heat pipe 31. Through the exhaust of the fan 42, the heat in the inner hole of the heat pipe 31 can be quickly transferred to the outside, thereby cooling the entire galvanometer. In addition, when it is necessary to disassemble the heat pipe 31, the ball head plug 46 can be pressed to retract its end and separate the notch 45. At this time, the entire bracket 43 can be rotated to disengage the fan 42 from one end of the heat pipe 31. After rotation, the telescopic end of the ball head plug 46 can be engaged into another notch 45 to fix the rotation position of the bracket 43, thereby improving the convenience of operation.

[0032] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
