Description

Technical Field

[0001] This utility model relates to the field of laser welding technology, specifically to a ventilation device for a laser welding machine. Background Technology

[0002] Laser welding is a highly efficient and precise welding method that uses a high-energy-density laser beam as a heat source. Laser welding can reduce the amount of heat required to a minimum, minimize the range of metallographic changes in the heat-affected zone, and minimize deformation caused by heat conduction. It can reduce the time required for welding thick plates and even eliminate the need for filler metal. It can weld a wide range of materials and can join various dissimilar materials. It can weld two metals with different physical properties (such as different resistances). It is widely used in the automotive manufacturing and electronics industries. However, laser welding machines often produce fumes during use, which pollute the environment and may have adverse effects on the health of workers. Therefore, ventilation devices are needed to treat the fumes generated during the use of laser welding machines.

[0003] Existing ventilation devices are widely used, but they can usually only handle solid particles in fumes and cannot absorb toxic gases. The treated exhaust gases are still quite harmful, and the solid particles collected by existing devices are not easy to clean. Therefore, a ventilation device for laser welding machines is proposed to address the above problems. Utility Model Content

[0004] The purpose of this invention is to provide a ventilation device for a laser welding machine to solve the problems mentioned in the background art, such as the inability of existing devices to absorb toxic gases and the inconvenience of cleaning.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

A water valve communicating with the water tank is fixedly connected to the front side of the water tank. Fixed frames communicating with the welding machine body are fixedly connected to the left and right sides of the welding machine body. Multiple suction pipes communicating with the fixed frames are fixedly connected to the side of the fixed frames away from the welding machine body. A horizontally arranged fixed pipe communicating with the suction pipe is fixedly connected to the end of the suction pipe away from the fixed frame. A connecting hose communicating with the fixed pipe is fixedly connected to the outside of the fixed pipe.

The filtered gas enters the inside of the HEPA filter block 12, and the purified gas passes through the high-pressure blower 13 and is discharged into the air. This design can dissolve the toxic gases in the fumes in the water and reduce the toxic substances in the discharged gas, preventing the gas from harming the health of the operators.

[0025] A mounting plate 14 is fixedly connected to the bottom end of the fixed cylinder 11. A mounting ring 15, which is fixedly connected to the top of the water tank 2 and communicates with the water tank 2, is provided on one side of the suction connector 9. Multiple bolts 16 are fixedly connected to the top of the mounting ring 15, and nuts 17 are threaded onto the outer side of the bolts 16. A collection assembly 18 is installed at the bottom end of the mounting plate 14. The collection assembly 18 includes a collection screen cylinder 181 installed at the bottom end of the mounting plate 14.

[0026] Workflow: Before use, power on the device and connect the external control device.

Install the collection component 18 at the bottom of the mounting plate 14, place the HEPA filter block 12 inside the fixed cylinder 11, and install the high-pressure blower 13 at the top of the fixed cylinder 11. Next, remove the connecting hose 7 inside the water tank 2 through the mounting ring 15, and screw the first threaded connector 8 onto the second threaded connector 184 at one end of the collection pipe 183.

This completes the installation of the fixed cylinder 11 and its connecting components. When performing laser welding using the welding machine body 1, start the high-pressure fan 13. The high-pressure fan 13 quickly exhausts the air from the fixed cylinder 11 and its connecting components, creating a negative pressure environment inside. The fumes generated by laser welding enter the inside of the fixed pipe 6 through the fixed frame 4 and the suction pipe 5. The fumes then pass through the connecting hose 7 and... The collection pipe 183 enters the inner side of the collection screen 181 at the top of the base 182. At this time, the solid particles in the smoke remain inside the collection screen 181, while the toxic gases dissolve in the water in the water tank 2. The filtered gas enters the inner side of the HEPA filter block 12 in the fixed cylinder 11 through the suction pipe 10. The HEPA filter block 12 performs final purification on the gas. The purified gas passes through the high-pressure blower 13 and is discharged into the air. This design allows the toxic gases in the smoke to dissolve in the water and reduces the amount of toxic substances in the discharged gas, preventing the gas from harming the health of the operators. When the device is in use at one end... Afterwards, the device can be cleaned. First, unscrew the nut 17 and the suction connector 9, remove the fixed cylinder 11 and its connecting components from the water tank 2, then open the water valve 3 to collect and treat the sewage. Remove the collection component 18 from the bottom of the mounting plate 14 to collect solid particles inside the collection screen cylinder 181. The setting of the collection component 18 and its connecting components makes the collection and cleaning of solid particles in the smoke more convenient and improves work efficiency. Finally, the high-pressure blower 13 can be removed and the HEPA filter block 12 can be replaced. This completes the cleaning of the device.
