The other end of each connecting rod 2 8 is respectively rotated to connect one end of the horizontal shaft 10, and the other ends of the two horizontal shafts 10 are respectively fixedly connected to the corresponding upper and middle parts of the connecting rod 1 6.

[0027] Each of the air outlet pipes 71 is fixedly connected to the air inlet of the air pump 16 through a hose 161. The air pump 16 is detachably connected to a filter cartridge 17. The air inlet of the filter cartridge 17 is connected to the air outlet of the air pump 16. The air pump 16 is connected to a movable component.

[0028] In this embodiment, the swing of the suction hood 7 is achieved by providing a drive assembly. After the welding gun 5 has been working for a period of time and has generated harmful gases, the suction hood 7 is controlled by the drive assembly to swing to both sides of the gun head of the welding gun 5. The exhaust fan 16 works to extract the gas. The exhaust fan 16 sucks the harmful gases from the suction hood 7 and finally discharges them into the air after passing through the filter cartridge 17. The filter cartridge 17 is detachable for easy replacement and cleaning.

[0029] The electric push rod 4 of the driving component can drive the support block 9 to rise and fall, and the support block 9 can drive the connecting rod 2 8 to swing, the connecting rod 2 8 drives the horizontal axis 10 to swing, and the horizontal axis 19 drives the connecting rod 1 6 to swing, thereby driving the suction hood 7 to swing.

[0030] The moving assembly includes an X-axis moving module 2, a Y-axis moving module 3 and a mounting plate 1. The lower side of the mounting plate 1 is fixedly connected to the fixed end of the X-axis moving module 2, the movable end of the X-axis moving module is fixedly connected to the fixed end of the Y-axis moving module 3, the movable end of the Y-axis moving module 3 is fixedly connected to the welding gun 5, and the movable end of the Y-axis moving module 3 is fixedly connected to the vacuum pump 16.

When the temperature exceeds a certain threshold, the controller controls the semiconductor cooling sheet 11 to work.

[0035] In this embodiment, the temperature sensor monitors the temperature of the gun tip in real time when the welding gun 5 is working. When the temperature is too high, the semiconductor cooling sheet 11 works to cool the gun tip, thereby extending the service life of the welding gun 5.

[0036] When in use, the mounting plate 1 of the device is installed in a suitable position, and the welding gun 5 is driven to move to the place where welding is required by the X-axis moving module 2 and the Y-axis moving module 3. When welding, the welding gun 5 is used for welding, and harmful gases are generated during welding. The driving component enables the suction hood 7 to swing to both sides of the welding head to absorb the exhaust gas. The exhaust fan 16 inhales the harmful gas from the suction hood 7 and finally discharges it into the air after passing through the filter cartridge 17. During the welding process, the temperature sensor monitors the temperature of the gun head in real time. When the temperature is too high, the semiconductor cooling sheet 11 works to cool it down.
