[0002] The airbag device of the car can prevent or reduce casualties in the event of a collision. The airbag mesh is an important component of the airbag. During assembly, the airbag mesh needs to be folded and loaded into the mold. Traditionally, it is mainly installed manually, but manual installation requires entering the mold area to install the airbag mesh, which is highly dangerous, and manual installation is not fixed, visual inspection is not standard, and production efficiency is slow.

[0003] Chinese patent CN 214872808 U discloses "a fully automatic feeding assembly for airbag mesh", which is equipped with a mesh placement slide, so that when the device is in use, the mesh is picked up by an industrial robot, and then the mesh is placed on the mobile platform, and then the mobile platform is controlled to move to the right by the servo reduction motor assembly, so that the mesh on the mobile platform can be sent to the hot pressing mechanism for hot pressing processing, realizing fully automated feeding and processing, reducing the number of operators, and effectively improving the processing efficiency of the product. However, the airbag mesh needs to be manually folded into the required shape before being sent to the hot pressing mechanism. Due to the material and special weaving method of the airbag mesh, it is not easy to produce fixed creases, so the industrial robot often fails to pick up the material accurately. Therefore, it is difficult to pick up the mesh by an industrial robot in the early stage and then place the mesh on the mobile platform, and how to feed the mesh on the mobile platform into the hot pressing mechanism in the later stage will also become a problem.
