These substances are not only easy to adhere to the optical lens protection sheet, but if not handled in time, they will even remain in the laser light path and block the laser transmission. Dust extraction is required during the paint removal process.

[0003] In the prior art, a patent with publication number CN206116102U discloses a copper flat wire dust removal device, which includes a base, a bottom plate is provided at the upper end of the base, the bottom plate is fixed to the base through a support frame, two layers of felt are placed between the bottom plate and the extrusion plate, and the bottom plate and the extrusion plate are fixed by bolts.

However, during the laser removal process, due to the influence of the paint removal environment, the smoke and dust generated during laser paint removal are easily confused in the air, and it is impossible to fully extract dust around the flat copper wire, resulting in poor dust extraction effect.

[0008] Two sets of limit modules are fixedly installed on one side of the mounting base. The two sets of limit modules are arranged outside the perforations and are vertically arranged between the two sets of limit modules.

[0023] In order to make the purpose, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below in conjunction with specific embodiments.

[0024] like Figure 1 、 Figure 2 、 Figure 3 and Figure 4 As shown, a dust extraction device for removing paint from flat copper wire comprises two sets of mounting base plates 3, wherein a support frame 1 is fixedly mounted on one side of one set of mounting base plates 3, a through hole 9 for accommodating the flat copper wire to pass through is provided at the center of the two sets of mounting base plates 3, brackets 5 are distributed in an annular manner between the two sets of mounting base plates 3, a dust collection cover 6 and a light shielding cover 7 are fixedly mounted on two adjacent sets of brackets 5, the dust collection cover 6 and the light shielding cover 7 are combined to form a polygonal frame, a dust extraction bin is formed between the polygonal frame and the two sets of mounting base plates 3, a dust extraction baffle 15 is slidably mounted on the light shielding cover 7, and an opening 16 for the laser to pass through is provided in the dust extraction baffle 15;

[0025] An inner dust collecting pipe 4 and an outer dust collecting pipe 8 are fixedly mounted on both sides of the light shielding cover 7. The inner dust collecting pipe 4 and the outer dust collecting pipe 8 are connected. The outer dust collecting pipe 8 is used to connect to the exhaust fan.

[0026] Two sets of limit modules 2 are fixedly installed on one side of the mounting base 3. The two sets of limit modules 2 are arranged outside the perforation 9 and are vertically arranged between the two sets of limit modules 2. The limit modules 2 are used to limit the flat copper wires of different sizes.

[0027] The limiting module 2 includes a fixed block 10, which is fixedly installed on one side of the mounting base 3, and a moving block 11 is slidably installed on the fixed block 10, and rollers 12 are movably installed on the moving block 11 and the fixed block 10. A waist-shaped hole 13 is opened inside the moving block 11, and a bolt 14 is arranged inside the waist-shaped hole 13.

[0028] In this embodiment, before the laser is emitted, the position of the dust extraction bin is first fixed by the four supporting frames 1, the flat copper wire is passed through the through-hole 9, and then the movement of the movable block 11 and the fixed block 10 in the limit module 2 is adjusted to change the distance between the rollers 12. The bolt 14 is inserted into the waist-shaped hole 13 in the movable block 11 to lock it, thereby adapting to flat copper wires of different specifications and ensuring that the flat copper wire is limited during the pulling process to prevent it from moving during the dust extraction;

[0029] When the laser emits light, the exhaust fan is connected through the external dust collecting pipe 8 to control the air volume. The air near the device enters the inside of the device through the light shielding cover 7. The positive pressure airflow generated by the air will drive the dust generated by the paint removal of the flat copper wire into the external dust collecting pipe 8 through the evenly distributed internal dust collecting pipe 4, thereby forming a uniform and stable positive air pressure on the surface around the flat copper wire. The airflow enters the dust extraction equipment through the external dust collecting pipe 8, so that dust extraction can be carried out stably.

[0030] As an implementation method, Figure 4 As shown, there are at least four groups of dust collection covers 6 and light shielding covers 7, and the dust collection covers 6 and light shielding covers 7 are staggered and combined to form a polygonal frame.

[0031] In this embodiment, a polygonal frame is formed by staggered dust collection covers 6 and light shielding covers 7 installed with the bracket 5. A dust extraction bin is formed between the polygonal frame and the two sets of mounting base plates 3, providing a working environment for laser paint removal and facilitating dust extraction.

[0032] As an implementation method, Figure 1 、 Figure 2 and Figure 4 As shown, the outer dust collecting pipe 8 is an arc-shaped structure, the inner dust collecting pipes 4 are evenly distributed on one side of the mounting base 3 , and the ends of the inner dust collecting pipes 4 are close to the through-holes 9 .

[0033] In this embodiment, the outer dust collecting pipe 8 and the inner dust collecting pipe 4 are connected, and the end of the inner dust collecting pipe 4 is close to the perforation 9. When the outer dust collecting pipe 8 is connected to the exhaust fan, the air volume is controlled and the dust smoke and airflow around the flat copper wire enter the dust extraction equipment through the outer dust collecting pipe 8, so that dust extraction can be carried out stably.

[0034] As an implementation method, Figure 1 、 Figure 2 As shown, the two groups of limit modules 2 are combined to form an L-shaped structure, and a gap for a flat copper wire to pass through is left between two adjacent groups of rollers 12.

[0035] In this embodiment, two sets of vertical limiting modules 2 are used to limit the outer four sides of the flat copper wire, and then the movement of the movable block 11 and the fixed block 10 are adjusted to change the distance gap between the rollers 12. The waist-shaped hole 13 and the bolt 14 are locked to adapt to flat copper wires of different specifications, ensuring that the flat copper wire is limited during the pulling process to avoid movement during dust extraction.

[0036] As an implementation method, Figure 3 As shown, an air inlet is provided inside the light shielding cover 7 , and the size of the air inlet is controlled by moving the dust extraction baffle 15 .

[0037] The dust extraction baffle 15 is provided with at least three groups of openings 16 , and screws are installed between the openings 16 and the light shielding cover 7 .

[0038] In this embodiment, the position of the dust extraction baffle 15 is adjusted to change the air intake volume entering the device, so that the air intake volume and the dust extraction volume are balanced, thereby avoiding the generation of local vortexes inside the device and achieving the best dust extraction effect.

[0039] Working principle: When in use, before the laser is emitted, first fix the position of the dust extraction bin by using the four support frames 1, pass the flat copper wire through the perforation 9, then adjust the movement of the movable block 11 and the fixed block 10 in the limit module 2, change the distance between the rollers 12, and lock it with the waist-shaped hole 13 and the bolt 14 to adapt to different specifications of flat copper wires, ensuring that the flat copper wire is limited during the pulling process to prevent it from moving during dust extraction;

[0040] When the laser is emitting light, the exhaust fan is connected through the outer dust collecting pipe 8 to control the air volume. The air near the device enters the device through the light shielding cover 7. The positive pressure airflow generated by the air will drive the dust generated by the paint removal of the flat copper wire into the outer dust collecting pipe 8 through the evenly distributed inner dust collecting pipe 4, thereby forming a uniform and stable positive air pressure on the surface around the flat copper wire. The airflow enters the dust extraction equipment through the outer dust collecting pipe 8, so that the dust can be extracted stably.

[0041] By adjusting the position of the dust extraction baffle 15, the air intake volume entering the device is changed, the air intake volume and the dust extraction volume are balanced, and local vortexes are avoided inside the device, thereby achieving the best dust extraction effect.
