Description

Method and device for taping curtain airbags The present invention relates to a taping mechanism and method for a curtain airbag that implements an anti-unraveling structure for a folding product through an automatic taping method, thereby shortening the production time of the curtain airbag and reducing manufacturing costs. Curtain airbags are installed along the roof line at the top of the side windows. Accordingly, in the event of a vehicle collision, it deploys downward in a shape that covers the side window to protect the occupants. Meanwhile, in order to install curtain airbags in a vehicle, after rolling up the curtain airbag cushion, a structure to prevent the rolled-up component from unraveling is required. The anti-loosening structure of the folding product can be implemented by assembling a strap fixed to the folding product to a fixing tab. However, as the assembly between the strap and the fixing tab is performed manually, the time required for the anti-loosening process increases, leading to a problem of reduced work efficiency. In addition, there is also the problem that the manufacturing cost of curtain airbags increases due to excessive costs incurred in manufacturing the straps. The matters described above as background technology are intended only to enhance understanding of the background of the present invention and do not constitute prior art already known to those skilled in the art. FIG. 1 is a drawing illustrating an airbag cushion according to one embodiment of the present invention. FIG. 2 is a drawing showing the shape of a tape wrapped around a folded product that is a roll-folded airbag cushion of FIG. 1. FIG. 3 is a drawing illustrating a state in which a folded product is clamped in a production facility for roll-folding and taping an airbag cushion in the present invention. FIG. 4 is a drawing illustrating the state in which the clamped folding part in FIG. 3 is moved to the taping work point. FIGS. 5 to 10 are drawings illustrating the process of automatically taping a folding product using a taping mechanism according to an embodiment of the present invention.
