Description

Technical Field

[0001] This utility model relates to the field of automotive airbag installation technology, specifically an airbag skin installation device. Background Technology

[0002] With the development of automotive technology, people's requirements for vehicles are gradually shifting from practicality to comfort. As a result, air suspension, which can buffer driving, dampen vibrations, and stabilize vehicles, has been widely used. Among these components, airbags are one of the important parts to achieve the above objectives.

[0003] The current assembly method for air suspension airbag assemblies typically involves placing the airbag base on a simple platform, attaching the airbag skin and top cover, and directly introducing compressed air through the air inlet of the top cover. Once the airbag skin is tightly fitted to the airbag base, the compressed air supply is stopped and the air is vented. The airbag is then checked for proper installation, and finally, compressed air is introduced into the airbag assembly for a leak test using soapy water. This assembly method has the following disadvantages: 1. The assembly process lacks positioning and guiding structures, making it prone to deviations. 2. The assembly platform lacks safety protection measures, resulting in low worker safety. 3. The assembly mechanism cannot adapt to the assembly requirements of various airbag models.

[0004] Furthermore, with the year-on-year increase in automobile sales, the demand for automotive production line parts has also increased significantly, leading to longer delivery cycles, including for automotive airbags. Given the continuously increasing delivery cycles and quantities of airbag orders, continuing to use existing tooling for installation cannot meet the delivery cycle requirements; new tooling is needed to meet the demands of the new production pace.
