[0036] Specifically, the device is suitable for plasma welding of frame plates and frames when processing the same batch of panel lights. During the welding process, the movable welding component 6 can be adaptively adjusted according to the model specifications of the panel lights, so that the position of the welding gun 604 and the welding point remains constant, thereby ensuring that the weld states of the panel lights produced in the same batch are the same.

[0056] Step 4: The movable welding assembly 6 welds the frame and the frame plate, the operating motor 9 drives the operating gear 10 to mesh with the ring gear 8, and the welding table 3 rotates. During this process, the movable welding assembly 6 is adaptively adjusted according to the welding position (because the frame to be welded is in the same position as the mold frame 4, the limiting wheel 605 always keeps in contact with the mold frame 4 due to the elastic force of the limiting spring 608 during the welding process. When the mold frame 4 rotates with the welding table 3, the limiting wheel 605 will provide different thrusts to the movable table 601 according to the change of the force state, so that The movable table 601 can be adaptively adjusted according to the shape of the mold frame 4 to ensure that the position of the welding gun 604 and the welding point is always in a constant state). At the same time, the smoke treatment component 20 adsorbs the smoke generated by welding (the smoke generated during welding will float on the outside of the smoke hood 2001. During the entire welding process, the driving motor 2007 always drives the spiral blade 2006 to rotate, and the smoke will diffuse into the smoke pipe 2002, and be pushed to the smoke outlet 2005 under the rotation of the spiral blade 2006, and discharged from the smoke exhaust pipe 2008 for collection).
