At this time, the multiple first clamping plates 26 correspond to the positions of the multiple support grooves 15 on the outer walls of the two support rods 14. Subsequently, the operation of the second electric telescopic rod 25 drives the first clamping plates 26 to move inward toward the support grooves 15, so that one end of the first clamping plate 26 contacts the inner wall of the support groove 15. Then, the third electric telescopic rod 27 pushes the second clamping plate 28 to contact the inner wall of the support groove 15, forming a three-dimensional fixation.

A protrusion 298 is provided at the other end of the spring 296. A signal sensor 297 is provided at the end of the protrusion 298 opposite to the first slot 295.

[0034] Specifically, the second electric slide rail 293 drives the second electric slider 294 to move, thereby moving the slide rail assembly 17. The second electric slider 294 presses against the protrusion 298. After the protrusion 298 compresses the spring 296, the two signal sensors 297 come into contact and send signals. At this time, the multiple second connecting plates 16 are aligned with the multiple first connecting plates 13 respectively.

The telescopic end of the sixth electric telescopic rod 2993 passes through one end of the positioning box 299 and is provided with a fixing block 2994.

[0036] Specifically, the slide rail assembly 17 is placed into the positioning box 299, the fifth electric telescopic rod 2991 is activated to push the push plate 2992 to position the slide rail assembly 17, and at the same time, multiple sixth electric telescopic rods 2993 drive the fixing block 2994 to clamp the side wall of the slide rail assembly 17 laterally, thereby clamping the slide rail assembly 17.

[0038] Specifically, the seventh electric telescopic rod 31 operates, adjusting the height of the first box 32 so that the first sleeve 37 is at the same level as the welding point. Then, the eighth electric telescopic rod 35 is activated, causing the first sleeve 37 to be inserted into the holes opened in the side walls of the first connecting plate 13 and the second connecting plate 16. Subsequently, multiple ninth electric telescopic rods 38 push the grinding plates 39 to fit against the inside of the holes. The second motor 36 drives the first sleeve 37 to rotate, thereby causing multiple grinding plates 39 to rotate and achieve grinding of the holes.

[0039] In this embodiment, the outer wall of the first sleeve 37 is provided with dust suction holes 393 in a circular array. The outer wall of the movable plate 397 is rotatably connected to the second sleeve 392.

One side wall of the collection box 396 is provided with a drawer. One side wall of the collection box 396 is provided with a first air pump 395. The two output ends of the first air pump 395 are respectively fixedly connected to the other ends of the two dust suction pipes 394.

[0040] Specifically, the first air pump 395 is activated, sucking in grinding debris through multiple suction holes 393, which is then collected into the collection box 396 via the second sleeve 392 and suction pipe 394.

[0041] In this embodiment, the flipping welding mechanism 4 includes two support frames 41 on the top side wall of the operation plate 1. Each of the two support frames 41 has a third motor 42 on one side wall. The output ends of the two third motors 42 are connected to the same flipping frame 43 through the third motors 42. A third electric slide rail 44 is opened on one side wall of the flipping frame 43. A third electric slider 45 is slidably connected to the inner side wall of the third electric slide rail 44.

[0042] Specifically, the two third motors 42 drive the tilting frame 43 to rotate to a horizontal position, and the third electric slider 45 moves on the third electric slide rail 44.

[0044] Specifically, the operation of the fourth motor 47 causes the first rotating block 48 to adjust the lateral angle of the welding torch 497, the operation of the fifth motor 492 causes the second rotating block 493 to change the longitudinal angle, the tenth electric telescopic rod 49 adjusts the welding distance, and drives the welding torch 497 to be aligned with the interface to be welded on the outside of one of the connecting columns 18 and the second connecting plate 16, while the heat dissipation component 499 simultaneously cools the welding area.

[0045] In this embodiment, a fourth electric slide rail 495 is provided on one side wall of the circular plate 494, and a fourth electric slider 496 is slidably connected to the inner side wall of the fourth electric slide rail 495. A welding gun 497 is provided at one end of the fourth electric slider 496. A hole is provided on one side wall of the circular plate 494, and an eleventh electric telescopic rod 498 is provided on the inner side wall of the hole. A silicone pad is provided at the telescopic end of the eleventh electric telescopic rod 498.

[0046] Specifically, the fourth electric slider 496 moves on the fourth electric slide rail 495, driving the welding torch 497 to move along the interface trajectory. Then, it is activated by the eighth electric telescopic rod 35, so that one end of the first sleeve 37 contacts the other end of the connecting post 18, making the other end of the connecting post 18 flush with one end of the first connecting plate 13.

[0047] In this embodiment, the top of the operation panel 1 is provided with two seat cushion frames 12, and each of the two seat cushion frames 12 is provided with two first connecting plates 13 on one side wall opposite to each other. The same support rod 14 is fixedly connected to one side wall of each of the two first connecting plates 13. The outer side walls of the two support rods 14 are provided with support grooves 15 in a circular array. The bottom of the inner side of each of the two positioning boxes 299 is provided with a slide rail assembly 17. The top side wall of the slide rail assembly 17 is provided with two second connecting plates 16. The second connecting plates 16 and the first connecting plates 13 are detachably connected with connecting posts 18.

[0048] Specifically, multiple connecting posts 18 are inserted into the corresponding polished holes of multiple second connecting plates 16 and multiple first connecting plates 13 through an external mechanism.

[0049] It should be noted that this invention is a car seat welding and flipping device. The user places the seat cushion frame on the top of the operating plate 1, inserting the first connecting plate 13 into the second slot 2995. Then, the user activates the fourth electric telescopic rod 291 to push the positioning block 292 towards the first connecting plate 13, so that the positioning block 292 contacts the side walls of the multiple first connecting plates 13, thereby positioning the seat cushion frame 12. Subsequently, the first electric slide rail 22 runs, causing the first electric slider 23 to drive the clamping block 24 to move towards each other, so that the side wall of the clamping block 24 contacts the outer wall of the support rod 14. At this time, the multiple first clamping plates 26 correspond to the positions of the multiple support slots 15 on the outer walls of the two support rods 14 respectively. Then, the second electric... The operation of the telescopic rod 25 drives the first clamping plate 26 to move inward toward the support groove 15, so that one end of the first clamping plate 26 contacts the inner wall of the support groove 15. Then, the third electric telescopic rod 27 pushes the second clamping plate 28 to contact the inner wall of the support groove 15, forming a three-dimensional fixation. After positioning, the fourth electric telescopic rod 291 is activated again, so that the positioning block 292 no longer contacts the side walls of the multiple first connecting plates 13. Subsequently, the operation of the first electric telescopic rod 21 drives the I-shaped plate 29 upward to the welding position. Then, the slide rail assembly 17 is placed into the positioning box 299. The fifth electric telescopic rod 2991 is activated to push the push plate 2992 to position the slide rail assembly 17. At the same time, multiple sixth electric telescopic rods 2993... The drive fixing block 2994 laterally clamps the side wall of the slide rail assembly 17, thereby holding the slide rail assembly 17. Subsequently, the second electric slide rail 293 drives the second electric slider 294 to move, thereby moving the slide rail assembly 17. The second electric slider 294 presses against the protrusion 298. After the protrusion 298 compresses the spring 296, the two signal sensors 297 come into contact and send signals. At this time, the multiple second connecting plates 16 are respectively aligned with the multiple first connecting plates 13.

[0050] Subsequently, the seventh electric telescopic rod 31 operates, adjusting the height of the first box 32 so that the first sleeve 37 is at the same level as the welding point. Then, the eighth electric telescopic rod 35 activates, causing the first sleeve 37 to insert into the holes in the side walls of the first connecting plate 13 and the second connecting plate 16. Next, multiple ninth electric telescopic rods 38 push the grinding plates 39 to fit against the inner side of the holes. The second motor 36 drives the first sleeve 37 to rotate, thereby rotating the multiple grinding plates 39 to grind the holes. Simultaneously, the first air pump 395 activates, sucking in grinding debris through multiple suction holes 393, collecting it in the collection box 396 via the second sleeve 392 and suction pipe 394. The first motor 33 drives the bidirectional threaded rod 34 to rotate, thereby moving the moving plate 397. The grinding plate 39 grinds all the holes at the weld joints, while the locking block 391 ensures that the dust collection component moves synchronously with the moving plate 397. After grinding, the inner walls of the holes are smooth and burr-free, ensuring that the connecting post 18 fits tightly into the hole after insertion. Multiple connecting posts 18 are inserted into the corresponding ground holes of multiple second connecting plates 16 and multiple first connecting plates 13 through an external mechanism. Subsequently, two third motors 42 drive the flipping frame 43 to rotate to a horizontal position, the third electric slider 45 moves on the third electric slide rail 44, the fourth motor 47 operates to adjust the lateral angle of the welding gun 497 by the first rotating block 48, the fifth motor 492 operates to change the longitudinal angle of the second rotating block 493, and the tenth electric telescopic rod 49 adjusts the welding distance, driving the welding gun 497 to align with one of the connecting posts. The welding interface between the circular plate 494 and the connecting post 18 on the outer side of the second connecting plate 16 is then connected. At this time, the circular plate 494 and the connecting post 18 are on the same horizontal plane. Subsequently, the eleventh electric telescopic rod 498 is activated to push the silicone pad into contact with one end of the side wall of the connecting post 18, making one end of the connecting post 18 flush with one end of the second connecting plate 16. At this time, the first motor 33 drives the bidirectional threaded rod 34 to rotate, thereby moving the moving plate 397 so that the first sleeve 37 and the connecting post 18 to be welded are at the same center point. Then, the eighth electric telescopic rod 35 is activated to make one end of the first sleeve 37 contact with the other end of the connecting post 18, making the other end of the connecting post 18 flush with one end of the first connecting plate 13. Subsequently, the fourth electric slider 496 moves on the fourth electric slide rail 495, driving the welding... The welding torch 497 moves along the interface trajectory, and the heat dissipation component 499 simultaneously cools the welding area to prevent overheating and damage to the workpiece. After the outer side welding is completed, the eighth electric telescopic rod 35 is activated, so that one end of the first sleeve 37 is no longer in contact with the other end of the connecting post 18. Subsequently, the third electric slider 45 moves again on the third electric slide rail 44, driving the welding torch 497 to align with the interface to be welded between one of the connecting posts 18 and the inner side of the first connecting plate 13, and repeats the welding work. When one side is welded, the third motor 42 drives the flipping frame 43 to rotate 180 degrees, and repeats the above steps to complete the welding of the other side, ensuring that the interface is fully enclosed in the welding. Finally, all electric telescopic rods are reset in sequence, the clamping plate and fixing block 2994 release the workpiece, and the first electric slider 23 returns to its initial position.Remove the finished workpiece and pull out the drawer of collection box 396 to clear away the debris.
