[0034] Please refer to Figure 1 and Figure 2 The embodiment of the present application provides a laser processing device 100, which comprises a laser 10, a nozzle 20 and a magnetic attraction piece 30. The laser 10 is provided with a light outlet (not shown), which is used for emitting laser and spraying protective gas. The nozzle 20 is arranged on the laser 10, and the nozzle 20 is provided with a ventilation cavity 21, which is communicated with the light outlet and the outside, and the laser and the protective gas are communicated to the outside through the ventilation cavity 21. The magnetic attraction piece 30 is arranged on the nozzle 20.

[0035] In the embodiment of the utility model, the magnetic attraction piece 30 is arranged on the nozzle 20, can magnetically attract metal dust, reduces the probability that metal dust enters the laser 10 through the ventilation cavity 21 of the nozzle 20, effectively protects the laser 10, increases the service life of the laser processing device 100.

[0036] It is worth mentioning that the laser 10 usually sprays protective gas during laser processing to avoid dust entering the inside of the laser 10. However, when laser processing is not performed, spraying of the protective gas also stops, which causes dust floating in the air to easily drift into the laser 10, affecting the service life of the laser 10. It is too high to keep spraying the protective gas all the time, so the application provides a laser processing device 100 capable of arranging a magnetic attraction piece 30 on the nozzle 20, which can effectively attract metal dust and prevent metal dust floating in the air from entering the laser 10.

[0037] Specifically, the laser 10 can emit laser light to perform welding, cutting and other processing. It can be understood that, in order to reduce dust pollution to the laser 10, the laser 10 can also spray protective gas during laser processing. It can be understood that the protective gas can include helium, argon, nitrogen and the like, which is not limited in the application.

[0038] The nozzle 20 is used to communicate with the outside and the light outlet, increases the path of dust through the light outlet to enter the laser 10, and reduces the probability of dust entering the laser 10. It can be understood that the ventilation cavity 21 can be arranged along the axis of the laser to facilitate the laser to pass through the ventilation cavity 21 and shoot to the outside.

[0039] The magnetic attraction piece 30 is used to attract metal dust by magnetic force. The structure of the magnetic attraction piece 30 has many, the magnetic attraction piece 30 can include a plurality of magnetic attraction blocks, a plurality of magnetic attraction blocks are uniformly or non-uniformly arranged on the nozzle 20; the magnetic attraction piece 30 can also include a plurality of magnetic attraction plug-in parts, the magnetic attraction plug-in parts are arranged in the nozzle 20. It is worth mentioning that the magnetic attraction piece 30 can be arranged on the outer surface of the nozzle 20, that is, the magnetic attraction piece 30 can be arranged separately from the ventilation cavity 21; the magnetic attraction piece 30 can also be arranged on the inner surface of the nozzle 20, that is, the magnetic attraction piece 30 is arranged on the cavity wall of the ventilation cavity 21; the magnetic attraction piece 30 can also be arranged through the nozzle 20, which is not limited in the application.

[0040] Please refer to Figure 2 In the embodiment of the utility model, the magnetic attraction piece 30 is arranged on the cavity wall of the ventilation cavity 21.

[0041] Therefore, since the protective gas is communicated to the outside through the ventilation cavity 21, when the laser 10 sprays the protective gas, the metal dust attracted by the magnetic attraction piece 30 can be discharged to the outside under the action of the protective gas, realizing automatic cleaning of the magnetic attraction piece 30.

[0042] It can be understood that the magnetic member 30 can be arranged on the cavity wall of the ventilation cavity 21 in many ways, and the magnetic member 30 can be fixedly connected with the ventilation cavity 21 by bonding, welding and the like, and the magnetic member 30 can be detachably connected with the ventilation cavity 21 by threaded connection, bolt connection and the like, and the application does not make specific limitation.

[0045] Referring to Figure 2 , in the embodiment of the utility model, the magnetic member 30 is annular to surround the ventilation cavity 21.

[0046] In this way, the magnetic member 30 can surround the ventilation cavity 21 and uniformly adsorb the metal dust in the ventilation cavity 21 to protect the laser 10 from metal dust pollution.

[0047] Referring to Figure 1 and Figure 2 , in the embodiment of the utility model, the cross-sectional area of the ventilation cavity 21 gradually decreases in the direction away from the laser 10.

[0048] In this way, the protective gas passes through the reduced flow section to increase the flow rate of the protective gas, so that the dust outside can be better blown away.

[0049] Further, referring to Figure 1 and Figure 2 , the ventilation cavity 21 includes a passing section 211 and a spraying section 213, the passing section 211 is communicated with the light outlet and the spraying section 213, the spraying section 213 is communicated with the passing section 211 and the outside, the cross-sectional area of the passing section 211 is constant in the direction away from the laser 10, and the cross-sectional area of the spraying section 213 gradually decreases.

[0050] In this way, the cross-sectional area of the passing section 211 far away from the outside is constant, which facilitates the passage of the protective gas, and the cross-sectional area of the spraying section 213 close to the outside is gradually reduced, so that the protective gas can be accelerated to spray outside.

[0051] It can be understood that the magnetic member 30 can be arranged on the spraying section 213, and the magnetic member 30 can also be arranged on the passing section 211, and the application does not make specific limitation.
