[0024] 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.

[0025] Reference Figures 1-3An embodiment of this utility model provides a fiber laser marking machine with a dustproof structure, including a base 1, a bracket 2 slidably connected inside the base 1, a controller 3 provided on the outer wall of the bracket 2, a fixed frame 4 fixedly connected to the outer wall of the bracket 2, a U-shaped block 5 provided on the outer wall of the fixed frame 4, a marking frame 6 fixedly connected to the outer wall of the U-shaped block 5, a hollow block 7 fixedly connected inside the U-shaped block 5, a push rod 8 slidably connected inside both the hollow block 7 and the U-shaped block 5, a transmission block 9 fixedly connected to the outer wall of the push rod 8, a U-shaped frame 10 rotatably connected inside the transmission block 9, a convex frame 11 rotatably connected to the outer wall of the U-shaped frame 10, a limit post 12 fixedly connected to the outer wall of the convex frame 11, a spring 13 fixedly connected to the top of the limit post 12, the outer wall of the spring 13 fixedly connected to the inner wall of the hollow block 7, and the bottom end of the limit post 12 slidably connected to the inside of the fixed frame 4. A moving component is provided inside the base 1.

[0026] Specifically, the coding frame 6 consists of a fiber laser, a galvanometer scanning system, a control system, and a cooling system. The fiber laser emits a high-energy laser beam, and the galvanometer system precisely guides the laser to perform rapid scanning on the object surface. The control system is connected to the controller 3 to manage the coding content, parameters, and process. The cooling system is located at the rear of the coding frame 6 to maintain the stability of the equipment during long-term operation. A short rod is installed inside the U-shaped frame 10 to rotate inside the transmission block 9 and the convex frame 11, facilitating the transmission of the transmission block 9 to the convex frame 11 via the U-shaped frame 10. The movement of the push rod 8 is offset by the interior of the hollow block 7. The elastic force of the spring 13 provides support for the limiting post 12 inside the fixed frame 4, thereby limiting the position of the U-shaped block 5 and the coding frame 6. The limiting post 12 slides in and out inside the fixed frame 4, and multiple grooves are provided inside the fixed frame 4 to cooperate with the limiting post 12, thereby facilitating the adjustment of the position of the U-shaped block 5.

[0027] Reference Figure 2 The moving component includes a fixed cylinder 16, the bottom end of which is fixedly connected to the inside of the base 1. A lead screw 15 is threadedly connected to the inside of the fixed cylinder 16. The outer wall of the lead screw 15 is set inside the bracket 2. A turntable 14 is fixedly connected to the top end of the lead screw 15. The outer wall of the fixed cylinder 16 is slidably connected to the inside of the bracket 2.

[0028] Specifically, the bracket 2 has a bearing inside that is connected to the lead screw 15. By rotating the turntable 14, the lead screw 15 rotates inside the fixed cylinder 16. Using the thread, the bracket 2 moves up and down between the base 1 and the fixed cylinder 16, thereby adjusting the height of the bracket 2.

[0029] Reference Figure 3The outer wall of the hollow block 7 is slidably connected to the inner wall of the fixed frame 4, the outer wall of the transmission block 9 is slidably connected to the inside of the hollow block 7, the outer wall of the convex frame 11 is slidably connected to the inside of the hollow block 7, and the outer wall of the limiting post 12 is slidably connected to the inside of the hollow block 7.

[0030] Specifically, the movement of the hollow block 7 is offset and limited by the inner wall of the fixed frame 4. A slider is provided at the contact end of the transmission block 9 and the hollow block 7, and slides inside the hollow block 7 to support and limit the movement of the transmission block 9. The convex frame 11 is composed of a slider, a block and a short rod. The slider and the short rod slide inside the hollow block 7 to offset and limit the movement of the convex frame 11. The movement of the limiting post 12 is offset and limited by the interior of the hollow block 7.

[0031] Reference Figure 4 The outer wall of the inkjet printer 6 is slidably connected to a protective sleeve 17, and a sealing ring 18 is provided inside the protective sleeve 17. The outer wall of the sealing ring 18 is provided on the outer wall of the inkjet printer 6.

[0032] Specifically, the protective sleeve 17 is brought into contact with the galvanometer set on the coding frame 6, so that the inside of the protective sleeve 17 slides towards the outer wall of the galvanometer and is secured by the sealing ring 18 at the connection between the protective sleeve 17 and the galvanometer, thereby protecting the galvanometer. By setting the bottom of the protective sleeve 17 to AR coated quartz glass and applying an anti-reflective coating, the use of the galvanometer is not affected, and the galvanometer is also protected from dust.

[0033] Reference Figure 5 An L-shaped block 19 is fixedly connected to the upper surface of the protective sleeve 17, and a trapezoidal block 20 is provided inside the L-shaped block 19; a circular block 21 is fixedly connected to the outer wall of the trapezoidal block 20, and a fixed block 23 is slidably connected to the outer wall of the circular block 21; the upper surface of the fixed block 23 is fixedly connected to the lower surface of the inkjet printer 6, and a sliding rod 22 is slidably connected to the inside of the fixed block 23; the outer wall of the sliding rod 22 is fixedly connected to the outer wall of the circular block 21, and a second spring 24 is fixedly connected to the outer wall of the circular block 21, and the outer wall of the second spring 24 is fixedly connected to the inner wall of the fixed block 23;

[0034] Specifically, the coding frame 6 fixes the fixed block 23, which in turn restricts the movement of the slide bar 22 and the circular block 21. One end of the spring 24 is fixed to the fixed block 23, and the other end is fixed to the circular block 21, thus limiting the range of movement of the circular block 21. Without external force driving the slide bar 22, the elastic force of the spring 24 pushes the circular block 21 and the trapezoidal block 20 to move to the right. A groove is provided inside the L-shaped block 19, which matches the outer wall of the trapezoidal block 20. One end of the L-shaped block 19 extends above the trapezoidal block 20, and the trapezoidal block 20 slides into the inner wall of the groove of the L-shaped block 19, thus limiting the L-shaped block 19 and preventing the protective sleeve 17 from accidentally slipping off when it is installed on the galvanometer of the coding frame 6.

[0035] Working principle: When using this inkjet printer, rotating the turntable 14 drives the lead screw 15 to rotate. A bearing is provided at the connection between the lead screw 15 and the bracket 2. The lead screw 15 rotates inside the fixed cylinder 16, thereby pushing the bracket 2 to move upward under the limit of the base 1 and the fixed cylinder 16. After the bracket 2 is adjusted to a suitable height, the controller 3 controls the inkjet printer frame 6. The inkjet printer frame 6 is composed of a fiber laser and a galvanometer, thereby performing non-contact coding on the surface of the object.

[0036] By pressing the push rod 8, the transmission block 9 is moved inside the hollow block 7, thereby moving the U-shaped frame 10 to the right. The U-shaped frame 10 then moves the convex frame 11 upward, causing the limiting post 12 to slide out of the fixed frame 4 and into the hollow block 7, thus squeezing the spring 13. With the limiting post 12 inside the hollow block 7, the U-shaped block 5 is no longer limited, making it convenient for the U-shaped block 5 and the inkjet printer 6 to move back and forth on the outer wall of the fixed frame 4. At the same time, when the inkjet printer 6 needs maintenance, the U-shaped block 5 and the inkjet printer 6 can also be disassembled.

[0037] By moving the protective sleeve 17 upward, it is brought into contact with the galvanometer. Simultaneously, the sealing ring 18 seals the installation of the protective sleeve 17. The protective sleeve 17 drives the L-shaped block 19 upward, and the inclined surface of the L-shaped block 19 pushes the trapezoidal block 20 to the left, thereby causing the round block 21 and the sliding rod 22 to move to the left inside the fixed block 23, compressing the spring 24. After the L-shaped block 19 moves to the appropriate position, it no longer pushes the trapezoidal block 20, and under the elastic force of the spring 24, it drives the round block 21 and the trapezoidal block 20 to the right, causing the trapezoidal block 20 to slide into the interior of the L-shaped block 19, thus limiting the L-shaped block 19. During use, this inkjet printer not only adjusts the position of the inkjet frame 6, but also allows for the installation and removal of the protective sleeve 17, facilitating the protection and dust prevention of the galvanometer of the inkjet frame 6.

[0038] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model 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 utility model should be included within the protection scope of the present utility model.
