The mobile dust collector 1 includes a purifier main unit 101, self-locking casters 102, an exhaust hose 103, and an air intake hood 104. Self-locking casters 102 are installed at the four opposite corners of the bottom of the purifier unit 101. An air extraction hose 103 is connected to the top of the purifier unit 101, and an air intake hood 104 is connected to the end of the air extraction hose 103 furthest from the purifier unit 101. The air extraction hose 103 has a folded and bent tube structure, and the air intake hood 104 and the air extraction hose 103 are sealed and fixedly connected. The robotic arm assembly 3 includes a six-axis robotic arm 301, a fixed base 302, and a welding torch 303. The fixed base 302 is located at the bottom of the six-axis robotic arm 301, and the output end of the six-axis robotic arm 301 is connected to... The welding torch 303 and the robot base 4 are fixedly installed and supported on the bottom of the six-axis robotic arm 301. The robot base 4 adopts an I-shaped structure. The entire mobile dust collector 1 operates using the structure of the purifier host 101 and is equipped with a flexible exhaust hose 103 connected to the air intake hood 104. This effectively removes fumes, metal particles and harmful gases generated during the welding process, reducing the interference of fumes on the welding quality. In addition, the entire mobile dust collector 1 can be flexibly moved and transported using the self-locking casters 102 installed at the bottom.

[0025] like Figs. 1 to 4As shown, the control cabinet 9 is placed horizontally on the top surface of the table 10, and the teaching pendant 8 is placed on the top surface of the control cabinet 9.

[0027] In the operation of the entire robotic arm assembly 3, the first welding machine 2 and the second welding machine 7 form a welding system. At the same time, the entire robotic arm assembly 3 performs welding operations on the workpiece according to the preset program and trajectory to complete various welding tasks.
