Description

Technical Field

[0001] This utility model relates to the field of laser engraving machine technology, and in particular to a focusing mechanism and a laser engraving machine. Background Technology

[0002] Laser engraving machines, also known as laser carving machines, improve carving efficiency, making the surface of the engraved area smooth and rounded. They also rapidly reduce the temperature of the non-metallic materials being carved, minimizing deformation and internal stress. They are widely used in the fine carving of various non-metallic materials. As the name suggests, a laser carving machine is an advanced device that uses lasers to carve materials. Laser carving machines differ from mechanical carving machines and other traditional manual carving methods. Mechanical carving machines use mechanical means, such as materials with extremely high hardness like diamond, to carve other objects.

[0003] When engraving on the surface of workpieces, the varying sizes of different workpieces can cause the engraving machine to lose focus, preventing the laser from concentrating on the workpiece. This affects the laser's effectiveness, hinders user operation, and reduces the practicality of the laser engraving machine. To address these issues, we propose a focusing mechanism and a laser engraving machine design. Utility Model Content

[0004] The purpose of this invention is to address the aforementioned shortcomings in the existing technology by proposing a focusing mechanism and a laser engraving machine.

[0022] 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.

[0023] Reference Figures 1-4 The focusing mechanism includes a base 1, with turntables 2 symmetrically arranged on both sides above the base 1. A support shaft 3 is connected to the middle of the two turntables 2 on opposite sides. The support shaft 3 is rotatably mounted on a support frame. A first drive motor 6 is installed on the end of one of the support shafts 3 and is fixed on the support frame.

[0024] like Figure 1 and Figure 3 As shown, a strip groove 7 is formed on the turntable 2, and the strip groove 7 is arranged along the radial direction of the turntable 2. A first connecting shaft 9 is provided between the two turntables 2. A slider 8 is connected to the end of the first connecting shaft 9. The slider 8 is placed in the strip groove 7, and a movable seat 21 is installed at the other end of the slider 8. A lead screw 18 is threadedly connected to the movable seat 21. The end of the lead screw 18 is rotatably mounted on a fixed seat 19, which is fixed to the turntable 2. A second drive motor 20 is installed at one end of the lead screw 18 and is fixed to the fixed seat 19. The second drive motor 20 rotates... Under the action, the distance between the first connecting shaft 9 and the center of the turntable 2 can be adjusted. That is, during use, as the lead screw 18 rotates, the lead screw 18 will move the turntable 2, thereby driving the support shaft 3 to move closer to or away from the first connecting shaft 9, thereby adjusting the distance between the first connecting shaft 9 and the center of the turntable 2. The support frame includes a sleeve 5, the bottom of which is vertically mounted on the base 1, and a support rod 4 is built into the top of the sleeve 5. The top of the support rod 4 is fixed to the support shaft 3 to ensure stable support of the first drive motor 6 and not affect the first drive motor 6 driving the turntable 2 to rotate.

[0025] like Figure 1 and Figure 2 As shown, a first connecting seat 10 is rotatably mounted in the middle of the first connecting shaft 9. A second connecting shaft 11 is connected to the top of the first connecting seat 10. A second connecting seat 12 is mounted on the top of the second connecting shaft 11. The second connecting seat 12 is rotatably mounted in a U-shaped seat 13 with its opening facing downwards via a rotating shaft. A drive shaft 14 is mounted on the top of the U-shaped seat 13. A bearing plate 16 is vertically mounted on the top of the drive shaft 14. When the turntable 2 rotates, the drive shaft 14 can drive the bearing plate 16 to perform a reciprocating lifting and lowering action. The adjustment of the distance between the first connecting shaft 9 and the center of the turntable 2 can adjust the lifting threshold of the bearing plate 16, realizing the fine-tuning operation of the lifting and lowering of the bearing plate 16.

[0026] Furthermore, limit plates 17 are installed at both ends of the slider 8. The limit plates 17 correspond to the side of the turntable 2, which improves the stability of the slider 8 sliding in the strip groove 7 and keeps the first connecting shaft 9 in a horizontal state.

[0027] Specifically, a mounting plate 15 is provided on the drive shaft 14, and the drive shaft 14 slides through the mounting plate 15. This utility model also provides a laser engraving machine, including an operating table 24. The top of the operating table 24 has a cavity, in which the base 1 is placed at the bottom of the cavity for fixation, and the mounting plate 15 is fixed on the top of the operating table 24 to limit the operation of the drive shaft 14, so that the support plate 16 can be stably lifted and lowered under the drive of the drive shaft 14. In order to further improve the lifting stability of the support plate 16, a guide shaft 22 is vertically installed at the bottom corner of the support plate 16, and the bottom of the guide shaft 22 slides through the mounting plate 15.

[0028] A crossbeam 27 is provided above the operating table 24. A second linear motor 28 is installed at the bottom of the crossbeam 27. A laser engraver 29 is installed on the second linear motor 28. A support column 26 is connected to the end of the crossbeam 27. The bottom of the support column 26 is installed on a first linear motor 25. The first linear motor 25 is fixed on the side of the operating table 24. In use, the workpiece is placed on the support plate 16. Then, by adjusting the distance between the first connecting shaft 9 and the center of the turntable 2, and by rotating the turntable 2, the focal length between the workpiece and the laser engraver 29 is adjusted. Then, the laser engraver 29 can be operated to engrave the workpiece.

[0029] It should be noted that a control cabinet 23 is installed on one side of the operating table 24. The control cabinet 23 contains a controller. The controller is connected to the first linear motor 25, the second linear motor 28, the laser engraver 29, the first drive motor 6, and the second drive motor 20 via wires. In actual use, the controller is one of the following: a PLC logic controller, a control motherboard, or a control host, and it controls the operation of the entire laser engraving machine.

[0030] 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.
