Problems solved by technology

[0005] The traditional airbag instrument panel laser weakening technology is mainly aimed at weakening the airbag frame, and during the weakening process, since the weakening has no effect on the appearance of the instrument panel, the holes drilled by the laser are all through holes, and the appearance of the instrument panel will appear obvious signs of weakening. Affect the appearance

Embodiment Construction

[0023] see figure 1 and figure 2 , the embodiment of the present invention includes: a seamless airbag laser weakening process, the specific steps include:

[0024] Step 1: Spray glue on one surface of body skeleton 1 on the dashboard and one surface on 3D-mesh2 respectively.

[0025] Step 2: Paste the glue-sprayed surface of body frame 1 on the dashboard and the glue-sprayed surface of 3D-mesh2.

[0026] Step 3: Put the body frame 1 on the instrument panel that has been glued with 3D-mesh in step 2 into an oven and heat at a temperature of 75~85°C.

[0027] Step 4: Spray glue on the other side of the body frame 1 on the instrument panel with 3D-mesh2 in step 3 and the surface of the skin 3 opposite to the leather side.

[0028] Step 5: Paste the glue-sprayed surface of the body frame 1 on the instrument panel with 3D-mesh2 and the glue-sprayed surface of the epidermis 3 with each other.

[0029] Step 6: Carry out vacuum adsorption on the body frame 1 on the instrument pa...

Abstract

The invention discloses a laser weakening process for a seamless airbag. The laser weakening process comprises the following specific steps: (1) spraying glue on a dashboard upper body framework and a 3D-mesh; (2) sticking the dashboard upper body framework to the 3D-mesh; (3) putting the dashboard upper body framework stuck with the 3D-mesh into an oven for heating; (4) spraying the glue on the dashboard upper body framework stuck with the 3D-mesh and a leather surface; (5) sticking the dashboard upper body framework with the 3D-mesh to the leather surface; (6) making vacuum absorption on the dashboard upper body framework; (7) punching through holes and shallow holes on the dashboard upper body framework by lasers with different proportions and along different weakening trajectories. The laser weakening process of the seamless airbag provided by the invention can not only meet the requirement of weakening strength, but also avoid obvious marks on the appearance.

Description

technical field [0001] The invention relates to the technical field of airbag laser weakening, in particular to a seamless airbag laser weakening process. Background technique [0002] With the continuous development of automobile technology, the requirements for the instrument panel, which integrates safety, functionality, comfort and decoration, are getting higher and higher, especially its safety. Classified by appearance, it is mainly divided into separate airbag dashboard and integrated airbag dashboard (Integrated airbag). At present, the airbags equipped on the dashboards of most cars in China are bright airbags. For the normal opening of the airbags, an airbag cover is usually designed above the airbags, and the airbags are released when they are opened. There is a visible installation line at the matching part of the instrument panel. The existing domestic models mainly include PASSATB5 series, SAIL series, general GL8 and so on. [0003] The separate airbag is re...
