Description

Technical Field

[0001] The utility model belongs to the technical field of laser welding dust removal, and specifically relates to a dust removal device for laser welding. Background Art

[0002] Laser welding dust removal refers to the use of special dust removal equipment and technical means to effectively collect, filter and purify the smoke, fumes, metal vapor and other harmful substances generated during the laser welding process;

[0003] A dust removal laser welding head with the authorization announcement number CN 220312090 U comprises a welding head body, a thread is provided at the bottom end of the outer wall of the welding head body, a threaded tube is threadedly connected to the outer wall of the thread, three evenly arranged sliders are fixedly connected to the outer wall of the threaded tube, a sliding tube is movably connected to the outer wall of the three sliders, and a positioning hole is provided on the outer wall of the sliding tube; the position of the sliding tube is fixed by tightening the bolt, so that the workpiece can be dusted during welding to prevent dust from affecting the welding effect; during dust removal, the motor drives the dust removal fan to rotate, so that the dust suction tube generates suction, and the dust generated during welding of the laser welding head is absorbed into the collection tube;

[0004] Although dust removal can be achieved for laser welding, there are still some problems in daily use. Given the open nature of the welding area, although negative pressure dust removal can be achieved, some fine dust will still escape into the surrounding environment. Secondly, the sparks generated by welding operations fly everywhere, which not only worsens the working conditions, but also poses a potential safety hazard of causing fire. Finally, when the position of the welding head changes and the distance from the dust suction port increases, in this case, for smoke far away from the dust source, especially when the welding work involves changes in different heights or complex geometric shapes, the dust removal device often shows a significant decrease in dust removal efficiency and cannot effectively capture and remove all the generated welding smoke. This not only weakens the overall dust removal effect, but also constitutes an obstacle to adapting to a variety of welding scenarios, reducing the flexibility and practicality of the equipment. Utility Model Content

[0005] In view of this, the utility model provides a dust removal device for laser welding, which can completely cover the welding site through the dust removal mechanism, so as to achieve efficient capture and export of welding smoke, while taking into account fire safety and operational convenience, thereby effectively improving the laser welding working environment, and can effectively isolate welding sparks and high-temperature smoke, prevent fire sources from splashing into the external working environment, reduce fire risks, enhance the sealing and fireproof performance of the interface with the welding equipment, avoid smoke leakage, and can move synchronously with the laser welding head, thereby realizing follow-up dust suction, improving the dust removal effect of the device on the laser welding machine body during welding, and facilitating coping with working scenes with different heights or shape changes.

[0012] An observation window is arranged in the observation port arranged at the front end of the outer arc surface of the dust removal cover.

[0013] The beneficial effects of the above technical solution of the utility model are as follows:

[0014] 1.
