[0015] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0016] Please see Figures 1-3 In this embodiment of the present invention, a laser polishing device with heat dissipation function includes a crossbeam 1. A guide rail 1 is fixedly connected to the front part of the upper surface of the crossbeam 1. A sliding block 10, an assembly box 1 2, and an assembly box 2 5 are slidably connected to the surfaces of the guide rail 1 4 and the guide rail 2 9, respectively. A top cover 11 is fixedly connected to the upper surface of the sliding block 10. A controller 12 is installed on the top of the top cover 11. The controller 12 is a programmable logic controller, which integrates a signal processing module and a drive output module. A connecting pipe 14 is installed on the upper part of the inner cavity of the assembly box 1 2. The connecting pipe 14 is a hollow tubular structure, and an optical fiber transmission cable and an electrical signal control cable are threaded inside it. The bottom of the controller 12 penetrates the upper surface of the top cover 11 and is fixedly connected and sealed to one end of the connecting pipe 14 installed on the upper part of the inner cavity of the assembly box 1 2 through a flange interface. The lower part of the connecting pipe 14 away from the top cover 11 is connected to the laser head operating cover 3 through a snap-fit quick connector. A heat dissipation assembly 13 is installed on the left side of the bottom of the inner cavity of the laser head operating cover 3. Guide rail 2 9 is fixedly connected to both the upper and lower parts of the front facade of beam 1. Buffer component 8 is fixedly connected to both ends of guide rail 1 4 and guide rail 2 9. Buffer component 8 is fixedly connected to the front facade of beam 1.
[0017] The heat dissipation assembly 13 includes a perforated plate 17 for connecting an external fan. A front panel 16 is fixedly connected to the outer wall of the perforated plate 17. Cavity blocks 18 are fixedly connected to both sides of the outer wall of the front panel 16. The cavity blocks 18 are rectangular block structures made of aluminum alloy. A through heat dissipation channel is opened inside the cavity block 18 along its length. The cross-section of the heat dissipation channel is circular. Several parallel heat dissipation fins are provided on the outer surface of the cavity block 18 to increase the contact area with air and improve heat dissipation efficiency.
[0018] A water pipe 15 and a nut 20 are respectively installed at the front end of the cavity block 18. The water pipe 15 passes through the front end of the cavity block 18 and communicates with the inner cavity of the cavity block 18. There are two sets of cavity blocks 18, and a copper pipe 19 is fixedly connected between the two sets of cavity blocks 18. The copper pipe 19 is inserted into the heat dissipation channel inside the cavity block 18. The outer diameter of the copper pipe 19 is adapted to the inner diameter of the heat dissipation channel. A layer of thermally conductive silicone grease is filled between the outer wall of the copper pipe 19 and the inner wall of the heat dissipation channel to eliminate assembly gaps and improve heat conduction efficiency. The two ends of the copper pipe 19 are fixedly connected to the cavity block 18 by an expansion joint process, so that the copper pipe 19 and the cavity block 18 form a tight interference fit to prevent the copper pipe 19 from loosening due to equipment vibration. Hinges 7 are installed on the sides of both assembly box 2 5 and assembly box 1 2. A door panel 6 is hinged to one side of the hinge 7. In use, the assembly boxes 1-2 and 2-5 that slide on the crossbeam 1 are used in conjunction with the cylinder; the cylinder is installed at the top right end of the crossbeam 1 and is connected to the top cover 11 on the assembly box 1-2 and the top cover 11 on the assembly box 2-5 respectively, for pushing the assembly box 1-2 and the assembly box 2-5. The controller 12 operates by receiving temperature signals from the internal temperature sensor, processing them through a pre-programmed internal algorithm, and outputting corresponding drive signals. These drive signals are transmitted via electrical control cables inside the connector 14 to the laser head mounted at the bottom of the laser head operating cover 3, controlling the laser head's start / stop and power adjustment. Simultaneously, laser energy is transmitted from the light source module to the laser head via fiber optic cables inside the connector 14, allowing the laser head to perform grinding operations on the workpiece surface. During laser head operation, the laser head operating cover 3, connected to the laser head, generates a significant amount of heat, which needs to be dissipated. This heat is dissipated by a fan located at the front of the cooling assembly 13. Specifically, the heat... Heat is drawn in through copper tube 19 and simultaneously conducted through the cavity block 18. The heat is then conducted through the wall of copper tube 19 to the inner wall of the heat dissipation channel of cavity block 18, and then to the heat dissipation fins on the entire cavity block 18 and its outer surface. A fan mounted on the perforated plate 17, through its operation, dissipates the heat from the heated liquid inside cavity block 18 and the heat received by copper tube 19. At the same time, circulating coolant enters the cavity block 18 and flows through copper tube 19 through water pipe 15, carrying away the accumulated heat through liquid heat exchange. The coolant flows back to the external cooling system through the return water pipe for cooling and then circulates again, thus achieving continuous and efficient heat dissipation by combining passive air cooling and active liquid cooling, meeting the heat dissipation needs of lasers of different power under different operating intensities.
[0019] When the temperature sensor detects that the device temperature exceeds the preset threshold, the controller 12 simultaneously sends a signal to reduce the output power of the laser head and increase the fan speed of the heat dissipation system, thereby realizing adaptive adjustment of the heat dissipation and laser output according to the actual working state, solving the technical problem of poor adaptability of traditional heat dissipation systems.
[0020] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
