[0023] Please refer to Figures 1-5 , an automotive lightweight seat frame welding device, including a bottom plate 1. An automated welding mechanism 2 and a clamping mechanism 3 are respectively and fixedly connected to the upper surface of the bottom plate 1. A fume purification mechanism 4 is arranged above the bottom plate 1. The fume purification mechanism 4 includes a purification box 401. A negative pressure pump 402 and a gas collection hood 404 are respectively arranged on the outer side of the purification box 401. A support frame 407 is snap-connected inside the purification box 401. Two groups of support columns 5 are fixedly connected to the bottom surface of the purification box 401. The bottom end of each group of support columns 5 is fixedly connected with two support seats 6. The bottom surface of each support seat 6 is in contact with the upper surface of the bottom plate 1. The clamping mechanism 3 can stably clamp the seat frame structure to be welded, thereby facilitating the automated welding mechanism 2 to weld the fixed seat frame. By providing the support columns 5, the purification box 401 can be supported and lifted, thereby facilitating leaving a space under the purification box 401 for conveniently lifting and placing the purification box 401 and storing other structures. By providing the support seats 6, the support area at the bottom end of the support columns 5 can be increased.

[0024] A key controller 413 is fixedly connected to the front surface of the purification box 401. An air inlet pipe 403, a connecting pipe 409 and a waste discharge pipe 414 are respectively fixedly connected to the inner wall of the purification box 401. The bottom end of the air inlet pipe 403 is fixedly and communicatively connected to the output end of the negative pressure pump 402. An exhaust hood 8 is arranged on the right side of the purification box 401. Two exhaust pipes 9 are fixedly and communicatively connected to the left side surface of the exhaust hood 8 and the right side surface of the purification box 401. By providing the exhaust hood 8 and the exhaust pipes 9, it is convenient to improve the exhaust efficiency of the purification box 401, thereby increasing the gas exchange rate inside the purification box 401.

[0025] A spray head 410 is arranged inside the purification box 401. The top end of the connecting pipe 409 is fixedly and communicatively connected to a solenoid valve 411. The upper surface of the spray head 410 is fixedly and communicatively connected to the bottom end of the connecting pipe 409. A shock-absorbing support plate 7 is fixedly connected to the left side surface of the purification box 401. The upper surface of the shock-absorbing support plate 7 is fixedly connected to the bottom surface of the negative pressure pump 402. By providing the shock-absorbing support plate 7, the purification box 401 and the negative pressure pump 402 can be connected, thereby increasing the stability and quietness of the negative pressure pump 402 during operation.

[0026] The input end of the solenoid valve 411 is fixedly communicated with an external connecting pipe 412. A smoke concentration sensor 405 is fixedly connected to the front surface of the air collecting hood 404. The negative pressure pump 402, the smoke concentration sensor 405, and the solenoid valve 411 are all electrically connected to the button controller 413 through wires. A handle support 10 is fixedly connected to the upper surface of the support frame 407. A pull rod 11 is fixedly connected to the inner wall of the handle support 10. A grip 12 is arranged inside the handle support 10. The inner wall of the grip 12 is rotatably connected to the outer surface of the pull rod 11. By providing the handle support 10, the pull rod 11, and the grip 12, the grip 12 can rotate around the outer surface of the pull rod 11 inside the handle support 10. Thus, after holding the grip 12 by hand, it is convenient to take out the support frame 407 and the filter structure inside it from the inside of the purification box 401, thereby facilitating the cleaning and replacement of the filter structure.

[0027] The input end of the negative pressure pump 402 is fixedly communicated with a three-way pipe 406. A filter element 408 is clamped inside the support frame 407. The two input ends of the three-way pipe 406 are fixedly communicated with the right side surface of the air collecting hood 404. A limiting slider 13 is fixedly connected to both the front surface and the back surface of the support frame 407. The outer surface of each limiting slider 13 is slidably connected to the inside of the purification box 401. By providing the limiting slider 13, it can slide up and down inside the purification box 401, thereby increasing the accuracy and smoothness of the relative installation of the support frame 407 inside the purification box 401.

[0028] The working principle of the present utility model is as follows: When in use, first connect the external connecting pipe 412 to an external continuous water supply mechanism, and connect the waste discharge pipe 414 to an external waste discharge hose. Then, use the clamping mechanism 3 to stably clamp the seat frame structure to be welded after splicing. After that, the automatic welding mechanism 2 performs automatic welding on the fixed seat frame. During welding, the smoke and dust concentration sensor 405 automatically detects the welding smoke and dust concentration around. When the smoke and dust concentration reaches the set range of the key controller 413, the key controller 413 controls the negative pressure pump 402 to be powered on to start extracting the gas around the welding environment through the air collecting hood 404 and the three-way pipe 406, and controls the solenoid valve 411 to be powered on to connect the connecting pipe 409 and the external connecting pipe 412. Then, the smoke and dust are drawn into the purification box 401 and are initially dusted by the water mist sprayed by the spray head 410. At the same time, the water mist mixed with impurities is discharged from the waste discharge pipe 414 and the external waste discharge hose. Then, after the filter element 408 filters the smoke and dust gas again, it is finally discharged outward from the exhaust pipe 9 and the exhaust hood 8, thus effectively purifying the welding smoke and dust. When the smoke and dust concentration sensor 405 detects that the welding smoke and dust concentration around is lower than the set range of the key controller 413 for a long time, the key controller 413 controls the negative pressure pump 402 to be powered off to stop pumping air and the solenoid valve 411 to be powered off to stop spraying water at the spray head 410. The design of the entire lightweight automotive seat frame welding device effectively solves the problem that the lack of a smoke and dust purification structure for purifying welding smoke and dust easily causes adverse effects on the environment and the health of operators due to the dispersion of welding smoke and dust.

[0029] The above is only the preferred specific implementation manner of the present utility model, but the protection scope of the present utility model is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present utility model, according to the technical solution and the inventive concept of the present utility model, makes equivalent substitutions or changes, and all should be covered within the protection scope of the present utility model.
