Description

Technical Field

[0001] This utility model relates to the technical field of laser cutting, specifically to a laser slag removal structure. Background Technology

[0002] Laser cutting utilizes a high-power-density laser beam to irradiate the material being cut, rapidly heating it to its vaporization temperature and causing it to evaporate and form a hole. As the beam moves across the material, the hole continuously forms a very narrow kerf (e.g., about 0.1 mm), thus completing the cutting of the material.

[0003] An existing automated laser cutting device, such as the one with patent publication number CN118893332A, pre-sprays an anti-reflective coating in front of the laser emitter's path to reduce cutting deviations caused by reflections, ensuring a more stable cutting process and obtaining higher-quality cuts. The anti-reflective coating is sprayed along the pre-cutting path, and the laser follows closely behind to cut, thus achieving precise coverage of the areas that need protection. This avoids unnecessary coating use, reduces material costs, and also prevents excessive coating residue in non-cutting areas, reducing the difficulty and time cost of subsequent cleaning.

[0004] However, the device generates some material slag splashing during use, which makes cleaning difficult and results in poor reliability. Utility Model Content

[0025] Please see Figure 1-4 A laser slag removal structure includes a laser cutting unit 1, a sliding sleeve connecting frame 2, a vertical sliding sleeve 3, a tightening screw sleeve 4, a tightening screw 5, a tightening handle 6, a sliding rod 7, a pull ring 8, a motor frame 9, a cleaning drive motor 10, and a brush 11. The lower outer side of the laser cutting unit 1 is connected to the front middle of the vertical sliding sleeve 3 via the sliding sleeve connecting frame 2. The inner wall of the vertical sliding sleeve 3 is vertically slidably connected to the outer wall of the sliding rod 7. One side of the vertical sliding sleeve 3 is connected to the inner side of the tightening screw sleeve 4. The inner wall of the tightening screw sleeve 4 is screwed to the outer wall of the tightening screw 5. The outer side of the tightening screw 5 is connected to the middle of the inner side of the tightening handle 6. The bottom end of the sliding rod 7 is connected to the middle of the top of the motor frame 9. The bottom end of the motor frame 9 is connected to the bottom end of the cleaning drive motor 10. A brush 11 is installed at the output end of the sweeping drive motor 10. The top middle of the slide rod 7 is connected to the bottom end of the pull ring 8, and a dust collection mechanism is also provided on the outside of the motor frame 9. According to the actual height of the board to be processed, the pull ring 8 is hooked, and the slide rod 7 slides vertically inside the vertical sliding sleeve 3. After reaching a suitable height, the brush 11 adheres to the surface of the board. Then, the tightening handle 6 is turned to make the tightening screw 5 rotate. The tightening screw 5 is screwed into the tightening sleeve 4 and acts inward to tighten the outside of the slide rod 7. Afterward, when the laser cutting unit 1 is running, the sweeping drive motor 10 can run. Under the connection of the motor frame 9, the brush 11 rotates stably, sweeping the residue on the surface of the board and absorbing it through the dust collection mechanism.

[0026] It also includes a baffle 12, with the upper outer side of the slide rod 7 connected to the inner side of the baffle 12; the baffle 12 can limit the upper part of the slide rod 7 to prevent it from falling out downwards and improve reliability.

[0027] The vacuuming mechanism includes a suction cup connecting frame 13, an annular suction cup 14, a delivery pipe 15, a cover plate 16, a vacuum cylinder 17, a hinge 18, a filter cartridge 19, an air pump 20, and an exhaust pipe 21. The lower outer side of the motor frame 9 is connected to the inner side of the annular suction cup 14 via the suction cup connecting frame 13. The output end of the annular suction cup 14 is connected to the inside of the cover plate 16 via the delivery pipe 15. The bottom middle of the cover plate 16 is movably connected to the front middle of the top of the vacuum cylinder 17 via the hinge 18. The output end of the vacuum cylinder 17 is connected to the inner side of the exhaust pipe 21. The exhaust pipe 21... An air pump 20 is installed on top, and a filter cartridge 19 is movably installed inside the dust collection cylinder 17. When the filter cartridge 19 is installed inside the dust collection cylinder 17 and the cover plate 16 is closed, the air pump 20 runs, and air is discharged from the exhaust pipe 21, creating a negative pressure inside the dust collection cylinder 17. This negative pressure then acts on the annular suction bucket 14 through the delivery pipe 15 to vacuum the area around the cleaning part. The dust enters the dust collection cylinder 17 and is filtered and collected by the filter cartridge 19. When cleaning is required, the air pump 20 stops, and the cover plate 16 is opened under the constraint of the hinge 18, so that the filter cartridge 19 can be removed.

[0028] It also includes a lifting rod 22, with the upper two ends of the filter cartridge 19 connected to both sides of the lifting rod 22 respectively; by holding the lifting rod 22, the filter cartridge 19 can be moved and removed inside the dust collection tube 17, improving convenience.

[0029] It also includes a locking handle 23, a moving pin 24, and a fixed pin bracket 25. The upper middle side of the outer end of the cover plate 16 is rotatably connected to the inner end of the locking handle 23. The output end of the locking handle 23 is connected to one side of the inner end of the moving pin 24. The upper middle rear side of the inner top of the dust collection cylinder 17 is connected to the inner side of the fixed pin bracket 25. When the cover plate 16 is closed, the locking handle 23 can be turned to rotate the moving pin 24 and pin it into the fixed pin bracket 25, so that the cover plate 16 is closed and fixed, improving reliability.

[0030] It also includes a sealing ring gasket 26, with the top ring side of the dust collection cylinder 17 connected to the bottom end of the sealing ring gasket 26; the sealing ring gasket 26 can seal the cover plate 16 after it is closed, improving reliability.

[0031] In summary, when using a laser cutting slag cleaning structure, based on the actual height of the material to be processed, the hook ring 8 acts on the slide rod 7, which slides vertically inside the vertical sliding sleeve 3. The baffle 12 limits the upper part of the slide rod 7 to prevent it from falling off. After reaching the appropriate height, the brush 11 adheres to the surface of the material. Then, the tightening handle 6 is turned to rotate the tightening screw 5. The tightening screw 5, through its screw engagement with the tightening sleeve 4, acts inward to tighten the outer side of the slide rod 7. Afterward, when the laser cutting unit 1 is running, the cleaning drive motor 10 can be operated. With the motor frame 9 connected, the brush 11 rotates stably, cleaning the residue on the surface of the material. When the filter cartridge 19 is installed inside the dust collection cylinder 17 and the cover plate 16 is in the closed state, turn the locking handle 23 to rotate the moving pin 24 and insert it into the fixed pin bracket 25, so that the cover plate 16 is closed and fixed. The sealing ring gasket 26 can seal the contact after the cover plate 16 is closed. When the air pump 20 is running, air can be discharged from the exhaust pipe 21 to create negative pressure inside the dust collection cylinder 17. Then, through the conveying pipe 15, it acts on the annular suction bucket 14 to vacuum the dust around the cleaning area. The dust enters the dust collection cylinder 17 and is filtered and collected by the filter cartridge 19. When cleaning is required, the air pump 20 is stopped, and the cover plate 16 is opened under the constraint of the hinge 18. The filter cartridge 19 can then be taken out by holding the lifting rod 22.

[0032] The laser cutting unit 1, the cleaning drive motor 10, and the air pump 20 are commercially available devices known to those skilled in the art. We are simply using them here without making any structural or functional improvements, and we will not elaborate further on them here.

[0033] 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.
