The dust box 3041 can cooperate with the air pump 3043 to generate negative pressure in the transmission ring 3011, so that the air can be extracted and the iron-based metal dust can be moved to the barrier net 3042, and intercepted by the barrier net 3042 for collection.

[0059] Brief description of the usage process: First, the closing mechanism 3 is powered on and started, and then the transmission ring 3011 is clamped on the positioning mechanism 2. After that, the welding point of the automatic welding machine body 1 will penetrate the transmission ring 3011 to weld the graphene RFID antenna chip, and then the vacuum pump 3043 will extract air from the transmission ring 3011. When the automatic welding machine body 1 is welded, the iron-based metal dust generated will be adsorbed by the magnetic ring 3022, and then the iron-based metal dust will move along the dust guide ring 3023 to the transmission ring 3011. After the welding is completed, the electromagnet 3021 is turned off, and the metal dust will move along the guide plate 3013 into the air supply pipe 3012, and then enter the air collecting ring 3031, and then enter the central pipe 3033 along the air guide groove 3032, and finally be intercepted by the barrier net 3042.
