Description

Technical Field

[0001] This utility model relates to the field of engraving machine technology, and in particular to a fully enclosed, simple desktop laser engraving machine. Background Technology

[0002] A laser engraving machine is a device that uses a high-energy-density laser beam to etch, cut, or engrave the surface of materials. It is widely used in various industries such as crafts, electronics manufacturing, signage engraving, and packaging printing. Laser engraving technology boasts advantages such as high precision, high speed, and non-contact processing, enabling fine engraving on a variety of materials including metal, wood, plastic, and glass. With the development of laser technology and increasing application demands, desktop laser engraving machines have emerged. Compared to industrial-grade equipment, desktop laser engraving machines are smaller and occupy less space, making them suitable for personal studios, small businesses, and educational training settings, meeting users' needs for miniaturized, high-precision engraving equipment.

[0003] Existing desktop laser engraving machines typically use fiber lasers, CO2 lasers, or semiconductor lasers as light sources and are equipped with precision control systems to ensure engraving accuracy and efficiency. The equipment generally includes core components such as an engraving platform, laser emitter, guide rail mechanism, and cooling system. Some desktop laser engraving machines adopt an open structure, facilitating operator adjustments to processing materials and engraving parameters, while others are equipped with semi-enclosed or fully enclosed safety enclosures to reduce the impact of laser radiation on operators and minimize the spread of smoke and debris during engraving. However, the protective enclosure and main frame of traditional equipment are usually designed as separate units, not connected, requiring multiple independent steps and numerous screws for installation. This not only increases assembly complexity but also increases the risk of installation errors, affecting the user experience. Therefore, a fully enclosed, simplified desktop laser engraving machine is proposed to address these issues. Utility Model Content

The front side wall of the top cover 23... The unit is fixedly connected to a handle 25, and a hinge 24 is installed on the left side of the inner wall of the outer casing 1 by bolts, and a U-shaped groove is provided on the outer side for protection. Mounting plates 26 are fixedly connected to both the front and rear sides of the inner casing 1. The Y-axis beam 2 is fixedly connected between the mounting plates 26. A switch 28 is provided on the front side of the outer casing 1. The switch 28 is electrically connected to the controller 27 to ensure stable signal transmission for equipment start-up and shutdown. A smoke exhaust fan 22 is provided in the middle of the rear side wall of the outer casing 1, and a flange is provided on the outside of the smoke exhaust fan 22 for connecting the smoke pipe to remove the smoke generated during operation, ensuring a clean working environment and air circulation. Profile limit plates are fixedly connected to the front and rear ends of the outer casing 1. These limit plates not only enhance the stability of the overall structure, but also prevent the equipment from moving or vibrating excessively during operation.

[0039] Reference Figures 3-5 The Y-axis moving mechanism includes two Y-axis moving seats 3, roller 7 and roller 8 rotatably connected inside the Y-axis moving seats 3, a first drive gear 5 rotatably connected inside the Y-axis moving seats 3, and a first toothed belt 9 that can connect roller 7 to the first drive gear 5. The Y-axis moving seats 3 are symmetrically arranged inside the outer casing 1 and are both located on both sides of the Y-axis crossbeam 2. There are two rollers 7 located on top of roller 8. Roller 7 slides in the top limiting groove of the Y-axis crossbeam 2, and roller 8 slides in the bottom limiting groove of the Y-axis crossbeam 2. The two rollers clamp the Y-axis crossbeam 2 to form a stable structure. A fixed guiding mechanism is provided to reduce shaking and deviation during movement, and improve the motion accuracy and durability of the equipment. One side of the first toothed belt 9 is fixedly connected to one side of the Y-axis beam 2, and it passes around the roller 7 and meshes with the first drive gear 5, ensuring effective power transmission. This allows the Y-axis moving seat 3 to be precisely controlled in the Y-axis direction. One side wall of the Y-axis moving seat 3 is fixedly connected to the first motor 4, and its output end is connected to the first drive gear 5 on that side. A synchronizing rod 6 is fixedly connected between the first drive gears 5. The synchronizing rod 6 is used to maintain the synchronous movement of the left and right Y-axis moving seats 3.

[0040] Reference Figures 1-3The X-axis moving mechanism includes an X-axis beam 10, an X-axis moving base 11, and rollers 15 and 16 rotatably connected inside the X-axis moving base 11, and a fixed column 12 fixedly connected inside the X-axis moving base 11 for mounting a second motor 13. Rollers 15 and 16 are arranged in an inverted triangle, clamping the X-axis beam 10 to ensure stability and accuracy during movement and avoid errors caused by vibration or offset. The fixed column 12 is positioned between the two rollers 15, with one end of each roller fixedly connected. A second drive gear 14 is fixedly connected to the output end of each roller 15. A second drive gear 14 is located inside the X-axis beam 10. The toothed belt 17, the second toothed belt 17, passes around the roller 3 15 and meshes with the second drive gear 14. The laser mechanism includes a heat sink 18 and a laser head 19. The roller 3 15 is installed on the outside of the X-axis moving seat 11. The laser head 19 is set at the bottom of the heat sink 18. A protective cover 20 is fitted on the outside of the laser head 19. The protective cover is made of high-strength heat-resistant material to effectively prevent the laser radiation from affecting the operator. The protective cover 20 is connected to the heat sink 18 by a fixing bolt 21. The controller 27 is electrically connected to the first motor 4, the second motor 13 and the laser head 19. The controller 27, the first motor 4, the second motor 13 and the laser head 19 are all existing technologies and will not be described in detail here.

[0041] Working principle: When using this equipment for laser engraving, the material to be engraved is placed inside the outer casing 1. Then, the controller 27 is controlled by switch 28 to start the equipment. When the first motor 4 starts, it will synchronously drive the first drive gear 5 to rotate, and the first drive gear 5 will move along the first toothed belt 9, causing roller 1 7 and roller 2 8 to slide on the Y-axis beam 2 at the same time, thereby causing the Y-axis moving seat 3 to move along the Y-axis beam 2. When the second motor 13 starts and drives the second drive gear 14 to rotate, the second drive gear 14 will also move along the second toothed belt 17, and under the action of roller 3 15 and roller 4 16, the X-axis moving seat 11 will move outside the X-axis beam 10, thereby changing the position of the laser head 19. During the operation of the equipment, the smoke generated during laser engraving can be drawn out by starting the exhaust fan 22 to avoid excessive smoke content inside the outer casing 1.

[0042] 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.
