The welding fume processing device for welding robot according to claim 1, characterized in that: the inside bottom position of collection dirt drawer (1201) activity even at box (2), chucking piece (1202) are rotated through pivot (1204) and are installed in the front portion of box (2) and be close to the below position, handle (1203) fixed mounting is in the front portion one end position of chucking piece (1202), dust filter bag (1205) fixed mounting is close to the bottom position in the inside of box (2), first net baffle (1206) fixed mounting is located the top position of dust filter bag (1205) in the inside of box (2), second net baffle (1207) fixed mounting is in the inside top position of box (2), activated carbon filler (1208) are filled between first net baffle (1206) and second net baffle (1207).
8. The welding fume processing device for welding robot according to claim 1, characterized in that: the clamping block (1202), the handle (1203) and the rotating shaft (1204) form a clamping assembly, and the number of the clamping assemblies is four.
9. The use method of the welding fume treatment device for welding robot of claim 1, characterized by comprising the following steps:
the method comprises the following steps: when the welding robot (1) works, the swing arm and the welding head (9) move, the welding head (9) drives the fume collecting hood (10) to keep synchronous movement in real time, so that the fume collecting hood (10) always keeps a position corresponding to a welding point, the fume inlet pipe (7) is soft, and the fume inlet pipe (7) is provided with a reserved length in the middle of a rotating arm of the welding robot (1), so that the fume inlet pipe (7) does not influence the normal work of the welding robot when the welding head (9) works;
step two: when welding smoke is generated, the fan (4) works, air is sucked into the box body (2) through the air exhaust pipe (5), the suction force of the air suction is transmitted into the welding smoke inlet pipe (7) through the box body (2), and smoke generated during welding enters the welding smoke inlet pipe (7) through the smoke collecting hood (10) and then enters the box body (2);
step three: welding fume is collected in the box body (2) and the suction force of the fan (4) rises, firstly, dust in the welding fume is filtered through the dust filtering bag (1205), then, the welding fume enters the interior of the activated carbon filler (1208) through the first net partition plate (1206), and finally, the welding fume is extracted out by the fan (4) through the second net partition plate (1207), the welding dust is filtered by the dust filtering bag (1205) and then falls into the interior of the dust collection drawer (1201), the handheld handle (1203) rotates the clamping block (1202) through the rotating shaft (1204), so that the clamping block (1202) falls off the dust collection drawer (1201), and the dust collection drawer (1201) can be taken out to pour out the dust;
step four: when the exhaust fume collecting hood (10) is installed, a connecting rod between two first inserting blocks (1102) and two second inserting blocks (1103) is held by hand, the two first inserting blocks (1102) and the two second inserting blocks (1103) are pulled in opposite directions at the same time, so that a connecting spring (1111) expands, a first T-shaped block (1106) and a second T-shaped block (1107) of the exhaust fume collecting hood (10) are clamped into two grooves of a welding head (9), the connecting rod is loosened, the two first inserting blocks (1102) and the two second inserting blocks (1103) are subjected to the contraction force of the connecting spring (1111) to move in opposite directions, and a first inserting column (1104) and a second inserting column (1105) are respectively inserted into the interiors of the first T-shaped block (1106) and the second T-shaped block (1107) through the side surface of the welding head (9).
