Description

Technical Field

[0001] The utility model relates to the technical field of automotive airbag, in particular to a leather covering and shaping device for a cover. Background Art

[0002] For the leather covering of the cover of an existing driver airbag module, since the adhesive glue used is an environment-friendly water-based glue, after applying the glue on the cover body and the leather and drying, the glue is activated by a certain temperature, and the leather is firmly pasted on the cover surface by pressing. The operation is carried out by the way of manual hot air activation and rolling. If the activation temperature is too low and the time is too short, part of the glue area cannot be activated, resulting in the leather not being firmly pasted on the cover surface. If the activation temperature is too high and the time is too long, problems such as discoloration and damage on the leather surface and the protrusion of the tear line on the cover will occur, affecting the overall appearance. At the same time, there is still incomplete activation of the glue in some parts, resulting in insecure pasting and not meeting the requirements.

[0003] There are two existing pasting and shaping methods. Method 1: After the cover leather is positioned on the cover surface, directly use a hot air gun to move and blow the leather surface manually to activate the glue, and then use tools to roll and press on the surface to paste and shape the leather. After verification, the length of the hot air activation time, the stability of the hot air distance, and whether the rolling area is fully covered will all affect the activation of the glue, resulting in some leather not being firmly pasted and unable to be completely pasted and shaped. Method 2: Directly use a tooling to fix the cover respectively, clamp the leather, heat the cover and the leather, then flatten the leather and attach it to the upper surface of the cover, and use a vacuum adsorption tooling to adsorb the leather on the cover surface for pasting. After verification, there are obvious large wrinkles on the leather surface after pasting, and obvious vacuum adsorption marks appear locally, affecting the overall appearance and unable to achieve pasting and shaping.

[0004] Therefore, through beneficial exploration and research, the applicant has found a method to solve the above problems, and the technical solution to be introduced below is generated under this background. Content of the Utility Model
