[0026] Specifically, the fixing plate 221 is fixedly connected to one end of the frame 21, the profiling mold frame 222 is fixedly connected to the fixing plate 221, four modules 223 are arranged in a rectangular shape in the profiling mold frame 222 and are fixedly connected to the fixing plate 221, and the profiling mold frame 222 and adjacent modules 223 are separated by a gap 225 that can accommodate four frames of the airbag frame 7. The profiling mold frame 222 is composed of 8 profiling blocks.

[0027] First, the instrument panel 8 is placed on the carrier assembly 4, the positioning assembly 5 limits the position of the instrument panel 8 on the carrier assembly 4, the pressing assembly 6 presses the instrument panel 8 on the carrier assembly 4, and then the four frames of the airbag frame 7 are respectively extended into the gap 225 between the profiling mold frame 222 and the module 223, and the suction cups 224 on the four modules 223 respectively suck the airbag frame 7. The driving assembly in the prior art respectively drives the workbench 1 and the frame 21 to move and press the instrument panel 8 on the carrier assembly 4 and the airbag frame 7 on the tire mold assembly 22. After pressing, the instrument panel 8 and the airbag frame 7 are vibrated and friction welded by the vibration friction welding equipment in the prior art. After forming, the suction cup 224 releases the airbag frame 7.

[0028] In the above structure, the instrument panel 8 and the airbag frame 7 are fixed respectively by the carrier assembly 4 and the tire mold assembly 22, and then the instrument panel 8 and the airbag frame 7 are welded together by vibration friction welding.

The two symmetrically arranged first clamping parts 61 are respectively used to clamp the two ends of the instrument panel 8, and the plurality of second clamping parts 62 are respectively used to clamp the installation positions of the instrument panel 8. The two first clamping parts 61 clamp the two ends of the instrument panel 8 on the carrier assembly 4, and three second clamping parts 62 are arranged on the workbench 1 to clamp the instrument panel 8 near the installation position. This arrangement facilitates the clamping and fixing of the instrument panel 8 on the carrier assembly 4, which not only ensures that the instrument panel 8 will not move during the movement of the workbench 1, but also ensures the welding position of the airbag frame 7 and the instrument panel 8.

[0032] like Figure 4 As shown, in one embodiment, the first pressing part 61 of the airbag frame vibration friction welding device includes a motor 611, a pressing rod 612 and a pressing block 613. The motor 611 is installed on the workbench 1. The driving end of the motor 611 is connected to one end of the pressing rod 612, and the other end of the pressing rod 612 is connected to the pressing block 613.
