[0025] When in use, by setting two exhaust hoods 10, two first branch pipes 12 and a second branch pipe 13, suction can be generated through the filtering mechanism during the welding process, so that the smoke generated by welding and the welding slag on the surface of the welding platform 2 can be transported to the filtering mechanism for filtration through the exhaust hood 10, the first branch pipe 12 and the second branch pipe 13 in sequence at the first time, and the filtered impurities are collected in the dust collecting funnel 20 for easy cleaning and transportation, so as to avoid the impurities being stored too dispersedly and inconvenient to collect, thereby increasing the workload. By setting a transparent plate 21 and a dust collecting funnel 20 with a transparent structure, it is convenient to observe the filtering and collection of impurities in real time, so as to avoid excessive accumulation of impurities and failure to discover them in time, which affects the normal operation of the filtering mechanism. Therefore, the utility model can collect and filter smoke more efficiently, and the operation is simple and convenient, which effectively reduces the cleaning work of the staff and improves the practicality of the equipment.

[0026] In this embodiment, a scraper 28 for cleaning impurities is rotatably installed on one side of the filter plate 26 close to the transparent plate 21, and a fan 25 is rotatably installed on the other side of the filter plate 26.

The two water inlet pipes 19 are respectively connected to the other ends of the two first branch pipes 12, and a solenoid valve 24 is provided on the surface of each water inlet pipe 19.

[0027] When in use, the fan 25 can be driven to rotate through the second motor 22 and the belt 27, thereby generating suction at the hood opening of the fume hood 10, collecting the fume during the welding process into the filtering mechanism. While the fan 25 is rotating, the scraper 28 can be driven to rotate through the transmission shaft at the same time to clean the surface of the filter plate 26 to prevent impurities from clogging the filter plate 26 and affecting the gas flowability. By opening a plurality of heat dissipation holes, the heat of the welding platform 2 can be released to the maximum extent, and the fan 25 can accelerate the gas flow at the bottom of the workbench 1, further improving the heat dissipation effect of the welding platform 2.

[0028] By setting up a water tank 17 filled with pure water for cleaning the filter mechanism, the first branch pipe 12 and the second branch pipe 13, when the welding operation is completed and the equipment is cleaned, the pure water in the water tank 17 is pumped into the first branch pipe 12 through two water inlet pipes 19 by two water pumps 18, and then flows into the equipment box 16 through the second branch pipe 13, so as to rinse out the impurities in the first branch pipe 12 and the second branch pipe 13 and discharge them from the dust collecting funnel 20 at the bottom of the filter chamber. During cleaning, a container is used to receive the waste water discharged from the dust collecting funnel 20, and at the same time, a part of the water flows to the welding platform 2 through the smoke collecting hood 10, so as to facilitate the cleaning of the welding platform 2 and improve the practicability of the equipment.

[0029] In this embodiment, the automatic welding mechanism includes a bracket 3. The bracket 3 is in a U-shaped structure with an opening facing downwards. The bracket 3 is fixedly installed on one side of the top of the workbench 1. A groove is formed in the top of the bracket 3, and a linear motor assembly 4 is fixedly installed in the groove.

A moving groove is formed in the bottom of the tripod 5, and a slider 8 in a T-shaped structure is slidably installed in the moving groove. A welding assembly 9 is fixedly installed at the bottom of the slider 8. A first motor 6 is fixedly installed on one side inside the tripod 5. A lead screw 7 is fixedly installed at the output end of the first motor 6. One end of the lead screw 7 passes through the outer surface of the slider 8 and is threadedly connected thereto. One end of the lead screw 7 is rotatably installed on the other side inside the tripod 5.

[0030] During use, the linear motor assembly 4 can drive the tripod 5 to move left and right along the bracket 3. The first motor 6 drives the lead screw 7 to rotate, thereby driving the slider 8 to slide back and forth inside the tripod 5, and then the welding assembly 9 can be driven to reach any position above the welding platform 2, so that the welding assembly 9 can automatically weld the workpiece fixed on the top of the welding platform 2. The welding assembly 9 has a height fine-tuning function, enabling the device to better meet the welding requirements.

Filtration is carried out through the filter plate 26, and the filtered impurities automatically fall into the dust collection funnel 20 for centralized collection, improving the efficiency of the equipment in absorbing fumes. At the same time, complex cleaning operations are avoided, improving the practicability of the equipment.
