Technical Field

[0001] The utility model relates to the field of industrial manufacturing, in particular to an exhaust gas treatment device for a laser welding machine. Background Art

[0002] Laser welding machine is a high-precision welding equipment that uses laser beams for welding. It uses the high-energy laser beam generated by the laser to focus on the welding area through an optical system. The metal material in the welding area is heated to above the melting point by the laser beam to form a molten pool, which is then cooled and solidified to achieve welding connection. Laser welding machines are widely used in automobile manufacturing, aerospace, electronic equipment, medical equipment and other fields. It can be used to weld different types of metal materials, such as stainless steel, aluminum alloy, titanium alloy, etc., as well as some plastics and ceramic materials. In addition to conventional welding, laser welding machines can also be used for special applications such as micro welding, deep welding, surface modification and adding materials.

[0033] Specifically, the base 1 is used to connect and support all parts, the processing box 2 is used to protect the internal parts, the exhaust fan 3 is used to suck the smoke generated by the evaporation and combustion of welding materials and surface coatings, and the gas generated during the welding process into the processing box 2 and discharge it out, the collar 4 is used to connect the filter 5 to facilitate its placement in the processing box 2, the filter 5 is an activated carbon with a large number of micropores and mesoporous structures on the surface, which can adsorb metal ions on its surface, the handle 7 is used to facilitate pulling out the collar 4 and replacing the filter 5, the pull rod 9 is used to facilitate pulling to unlock the entire device so as to achieve quick fixation and quick disassembly, and the connecting rods 10 on both sides are used to pull the plug rod 11 to achieve the linkage effect, the plug rod 1 1 cooperates with the handle 7, the rod 11 can be fixed by inserting it into the handle 7, and can be unlocked by pulling it out. The spring 12 is used for resetting. When the pull rod 9 is pulled, the spring 12 will be squeezed to store kinetic energy.

The rear side of the bottom of the smoke collecting port 15 is fixedly connected to the top of the fixed plate 16.

[0035] Specifically, the fixed plate 16 and the fixed frame 17 are used to connect and support the clamping assembly, and the motor 18 is used to output power to the clamping assembly. The motor 18 drives the rotating rod 19, and the rotating rod 19 drives the turntable 20 to rotate. The turntable 20 will push the push rod 21, and then the clamp 22 will move. The clamp 22 is used to clamp the workpiece to be welded to ensure that the workpiece is stable and will not move around. The limiting rod 23 and the limiting groove 24 have the same function, which is to limit the movement direction of the clamp 22 to ensure that the clamp 22 can only move left and right toward the center without moving around. The clamp 22 firmly clamps the workpiece to make the workpiece stable, and there will be no phenomenon of loose clamping, causing the workpiece to fall off, and causing the workpiece to be damaged.

[0036] Working principle: When using this device, first control the motor 18 to rotate through an external power supply, and the motor 18 drives the rotating rod 19 to rotate, and the turntable 20 connected to the rotating rod 19 will rotate accordingly, and the push rod 21 is pulled to drive the clamping plate 22 to move toward the middle, so that the workpiece is firmly clamped to ensure that the workpiece will not move around and shake, which is convenient for workers to operate. At this time, the exhaust fan 3 is controlled by an external power supply, and then the welding operation can be started. A large amount of harmful gas will be generated during welding. Through the rotation of the exhaust fan 3, the smoke will gather in the smoke collecting port 15, and be sucked into the processing box 2 through the exhaust pipe 14, and then pass through the filter 5. The activated carbon is filtered to absorb the harmful gas and then discharged into the air from the exhaust fan 3. After a period of use, the activated carbon in the filter 5 is exhausted and needs to be replaced in time. At this time, the pull rod 9 is pulled to drive the connecting rod 10 to pull the plug rod 11 to move, and the plug rod 11 will be separated from the handle 7 to unlock it. Then the handle 7 is pulled to pull out the ring 4, driving the filter 5 to be pulled out together, and then the filter 5 is taken out and replaced with a new filter 5. Then the pull rod 9 is pulled to reinsert the ring 4 into the treatment box 2. At this time, the pull rod 9 is released, and the spring 12 will push the plug rod 11 to reinsert the handle 7, thereby fixing it.
