These limitations not only affect marking efficiency but also restrict the marking machine's adaptability to workpieces of different thicknesses or heights. To overcome these technical difficulties and improve the flexibility and working efficiency of the marking machine, and considering that the working range of the laser emitter is often limited due to the design limitations of traditional marking machines, making it difficult to meet the seamless splicing marking requirements of large-format workpieces, this utility model proposes a large-format seamless splicing marking 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. 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.

[0023] Please see Figure 1-6 This utility model provides a technical solution: a large-format seamless splicing marking machine, including a frame 1, a worktable 2 on the frame 1, longitudinal guide rails 3 on both sides of the worktable 2, a crossbeam 4 above the worktable 2, the crossbeam 4 moving along the longitudinal guide rails 3, a transverse guide rail 5 on the crossbeam 4, and a moving vehicle 6 on the crossbeam 4, the moving vehicle 6 moving along the transverse guide rail 5;

[0024] The mobile vehicle body 6 is connected to a laser emitter 8 via a height adjustment component 7. The laser emitter 8 is equipped with a laser emitting head 801, which faces the worktable surface 2.

[0025] The frame 1 serves as the supporting structure for the entire equipment, ensuring the stability and reliability of the marking machine. The worktable 2 provides a flat processing surface for placing the workpiece to be marked. The longitudinal guide rail 3 and the transverse guide rail 5 guide the precise movement of the crossbeam 4 and the moving carriage 6, respectively, ensuring that the laser emitter 801 can mark according to the predetermined trajectory.

[0026] like Figure 3 As shown, in order to adjust the height of the laser emitter 801 relative to the worktable 2, specifically, the height adjustment component 7 includes a vertical plate 701, which is fixedly installed on the mobile vehicle body 6. Inside the vertical plate 701, a lead screw 703 is rotatably connected via a first motor 702. The first motor 702 is fixedly installed on the side wall of the vertical plate 701, and the output shaft of the first motor 702 is fixedly connected to one end of the lead screw 703. When the first motor 702 is started, the output shaft of the first motor 702 drives the lead screw 703 to rotate. A lifting platform 704 is slidably connected to the side wall of the vertical plate 701 via the lead screw 703. The lifting platform 704 is engaged with the side wall of the lead screw 703, and the laser emitter 8 is fixedly installed on the side wall of the lifting platform 704.

[0027] The first motor 702 drives the lead screw 703 to rotate, which in turn drives the lifting platform 704 to slide up and down on the vertical plate 701, thereby adjusting the height of the laser emitter head 801 to accommodate workpieces of different thicknesses or heights.

[0028] like Figure 3 As shown, in order to reduce the sliding friction between the lifting platform 704 and the vertical plate 701, specifically, multiple rollers 705 are provided on the side wall of the lifting platform 704, and a track 706 is provided on the side wall of the vertical plate 701. The rollers 705 are rotatably connected to the track 706, as shown. Figure 3 As shown, there are two tracks 706, which are arranged in parallel on the vertical plate 701. Multiple rollers 705 are arranged in two rows, and the two rows of rollers 705 are respectively connected to the corresponding tracks 706. The cooperation between the rollers 705 and the tracks 706 can reduce the sliding friction of the lifting platform 704 on the vertical plate 701 and improve its service life.

[0029] like Figure 2 and Figure 4 As shown, in order to enable the moving vehicle body 6 to move on the crossbeam 4, specifically, the transverse guide rail 5 includes a transverse slide rail 501 and a transverse gear 502. The transverse slide rail 501 and the transverse gear 502 are fixedly connected to the side wall of the crossbeam 4. The bottom of the moving vehicle body 6 has a first slider 601, which is slidably connected to the transverse slide rail 501. The moving vehicle body 6 is equipped with a third motor 11, and the output shaft of the third motor 11 is fixedly connected to a gear that meshes with the transverse gear 502.

[0030] like Figure 2 and Figure 5 As shown, in order to enable the crossbeam 4 to move on the longitudinal guide rail 3, specifically, the longitudinal guide rail 3 includes a longitudinal slide rail 301, which is fixedly connected to the side wall of the frame 1. An end support frame 9 is fixedly connected to each end of the crossbeam 4. A second slider 901 is fixedly connected to the bottom of the end support frame 9. The second slider 901 is slidably connected to the longitudinal slide rail 301. Each longitudinal guide rail 3 also includes a longitudinal toothed rod 302, which is fixedly connected to the side wall of the frame 1. A second motor 10 is provided on the side wall of the end support frame 9 on the same side as the longitudinal toothed rod 302. A gear that meshes with the longitudinal toothed rod 302 is fixedly connected to the output shaft of the second motor 10.

[0031] The moving vehicle body 6 slides on the transverse slide rail 501 via the first slider 601 at its bottom, while the third motor 11 drives the gear to mesh with the transverse rack 502, thereby realizing the lateral movement of the moving vehicle body 6 on the crossbeam 4. Similarly, the crossbeam 4 slides on the longitudinal slide rail 301 via the second sliders 901 at both ends, and the second motor 10 drives the gear to mesh with the longitudinal rack 302, thereby realizing the longitudinal movement of the crossbeam 4 on the longitudinal guide rail 3.

[0032] like Figure 2 and Figure 5 As shown, in order to prevent the mobile vehicle body 6 from being damaged by impact when it moves to the end of the crossbeam 4, specifically, anti-collision blocks 12 are fixedly installed at both ends of the crossbeam 4. The anti-collision blocks 12 are made of rubber. The anti-collision blocks 12 prevent the mobile vehicle body 6 from being impacted when it moves to the end of the crossbeam 4, thus protecting the equipment from damage.

[0033] Specifically, the frame 1 is provided with an outer shell 13, and the outer shell 13 is provided with a longitudinal bellows cover 14 for covering the longitudinal guide rail 3. The crossbeam 4 is provided with a transverse bellows cover 15 for covering the transverse guide rail 5. The outer shell 13, the longitudinal bellows cover 14, and the transverse bellows cover 15 provide protection and dust protection for the equipment, ensuring that the equipment can work normally in harsh environments.

[0034] Work process:

[0035] First, place the workpiece to be marked on the worktable 2, and adjust the height of the laser emitter 801 as needed. By starting the first motor 702, the lead screw 703 is driven to rotate, which in turn drives the lifting platform 704 to slide up and down until the laser emitter 801 reaches the required height.

[0036] Then, according to the requirements of the marking pattern or text, the movement trajectory of the moving vehicle 6 and the crossbeam 4 is set through the control system. The second motor 10 and the third motor 11 are started, driving the crossbeam 4 to move on the longitudinal guide rail 3 and the moving vehicle 6 to move on the crossbeam 4, respectively. During the movement, the laser emitter 801 marks the workpiece according to the set trajectory.

[0037] During movement, the anti-collision block 12 provides protection, preventing the moving vehicle body 6 from impacting the end of the crossbeam 4. Meanwhile, the outer shell 13, the longitudinal bellows cover 14, and the transverse bellows cover 15 provide necessary protection and dust protection for the equipment.

[0038] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
