As an important component of the interior of the car, the seat frame is usually assembled from several rigid materials. The traditional automobile seat back frame usually has a serpentine spring directly fixed to the seat back side panel by welding.

[0033] Furthermore, the first clamping mechanism 4 can be used to clamp the back plate. After the back plate is placed above the welding table 1, the transmission shaft 20 is driven by the first motor 22 to rotate, so that the clamping plate 305 moves to clamp and fix the support rod 7. At the same time, the transmission shaft 20 drives the third trapezoidal gear 19, the second trapezoidal gear 18, and the rotating shaft 17 to rotate through the fourth trapezoidal gear 21, and then the rotating shaft 17 drives the first trapezoidal gear 16 and the threaded rod 401 to rotate.

[0035] Furthermore, the fixing mechanism 3 can be used to fix the first reinforcing spring 8 and the headrest slot 9. After the first reinforcing spring 8 and the headrest slot 9 are fixed on the lifting plate 302, the lifting plate 302 is pulled downward by the electric telescopic rod 301, so that the first reinforcing spring 8 and the headrest slot 9 can contact the support rod 7, thereby achieving the effect of welding and fixing.

When the clamping gear 502 rotates, it will drive the first clamping gear rod 503 and the second clamping gear rod 504 to move toward the middle, so that the lower clamping block 505 and the upper clamping block 506 will clamp the inner plate 10 toward the middle. At the same time, when the first clamping gear rod 503 moves upward, it will drive the movable clamping rod 507 upward, so that the movable clamping rod 507 will clamp the middle of the inner plate 10, thereby fixing the inner plate 10.

[0038] A backboard assembly is provided on the upper surface of the welding table 1, and the backboard assembly includes a backboard body 6, a support rod 7, a first reinforcing spring 8, a headrest slot 9, an inner plate 10, and a second reinforcing spring 11.

After the inner panel 10 and the second reinforcing spring 11 are welded, the inner panel 10 and the second reinforcing spring 11 are flipped to the inside of the back panel body 6 by the set flipping mechanism 2, and then the inner panel 10 and the second reinforcing spring 11 are welded to the back panel body 6 by the first welding arm 101, thereby achieving the effect of improving welding efficiency.

[0040] Working principle:

[0041] When using the welding device, the back plate assembly is first placed on the welding device, and the first motor 22 drives the transmission shaft 20 to rotate, so that the clamping plate 305 moves to clamp the support rod 7. At the same time, the transmission shaft 20 drives the third trapezoidal gear 19, the second trapezoidal gear 18, and the rotating shaft 17 to rotate through the fourth trapezoidal gear 21, and then the rotating shaft 17 drives the first trapezoidal gear 16 and the threaded rod 401 to rotate. When the threaded rod 401 rotates, it pushes the movable clamping plate 402 inward. When the movable clamping plate 402 moves, the three-layer gear 408 will move on the fixed tooth groove 409, so that the fixed tooth groove 409 will drive the three-layer gear 408 to rotate. When the three-layer gear 408 rotates, it will drive the vertical gear rod 407 to move downward, and then the vertical gear rod 407 pulls the straight groove rod 405 downward through the pulling rod 406, and then the straight groove rod 405 pulls the pulling rod 406 to move downward to clamp and fix the seat back plate body 6. When the pressing rod 404 moves downward, The connecting rod 403 is moved toward the middle inside the straight groove rod 405, so as to achieve the effect of adapting the curvature of the surface of the seat back plate body 6 to fix, and at the same time, the second motor 501 is started to drive the clamping gear 502 to rotate. When the clamping gear 502 rotates, it will drive the first clamping gear rod 503 and the second clamping gear rod 504 to move toward the middle, so that the lower clamping block 505 and the upper clamping block 506 will clamp the inner plate 10 toward the middle. At the same time, when the first clamping gear rod 503 moves upward, it will drive the movable clamping rod 507 upward, so that the movable clamping rod 507 will clamp the middle of the inner plate 10, so as to achieve the effect of fixing the inner plate 10, and then start the flipping motor 202 to drive the flipping shaft 203 to rotate, and drive the flipping frame 204 to flip through the flipping shaft 203. The inner plate 10 can be flipped into the inside of the seat back plate body 6 through the set flipping mechanism 2, and then the second reinforcing spring 11 is continued to be welded to the seat back plate body 6 through the set first welding arm 101, so as to achieve the effect of welding the back plate assembly as a whole.
