Description

Technical Field

[0001] The utility model relates to the technical field of automobile parts assembly, in particular to an air bag pressing machine. Background Art

[0002] After being sewn, the automobile airbag needs to be folded, glued and hot-pressed so that it can be quickly unfolded and filled with air when a collision occurs. In traditional technology, when hot-pressing the automobile airbag, the folded automobile airbag is generally placed between the upper pressing platform and the lower pressing platform of a pressing machine, and the folded automobile airbag is squeezed by the upper pressing platform and the lower pressing platform to achieve hot pressing of the automobile airbag. However, at the moment of pressing, the automobile airbag is subjected to an instantaneous impact when the upper pressing platform and the lower pressing platform contact. The part that contacts first bears the impact force first and then diffuses to the surrounding area, resulting in a large difference between the pressure on the part that contacts first and the pressure on the surrounding area. The part that contacts first overflows due to excessive pressure, and the pressure on the surrounding area is small and cannot be fully bonded. There is a technical problem of poor bonding effect due to uneven force during the hot pressing process of the automobile airbag. Utility Model Content

The lifting guide rod 24 is connected to the pressing platform 30, wherein the lifting guide member 23 is a linear bearing, and the lifting guide rod 24 connected to the pressing platform 30 is guided to move by the lifting guide rod 24, which is beneficial to improving the displacement accuracy of the pressing platform 30.

[0039] like Figure 1 to Figure 2 As shown, the lower pressing platform 30 is used to place the automobile safety airbag, and the upper pressing platform 40 is spaced apart from the lower pressing platform 30 and connected to the buffer mechanism 50 .

[0040] like Figure 1 As shown, there are multiple buffer mechanisms 50 , and each buffer mechanism 50 is connected to a side of the upper pressing platform 40 facing away from the lower pressing platform 30 .

[0041] Specifically, Figure 3As shown, each buffer mechanism 50 includes a buffer guide 51, a buffer guide rod 52, a limit member 53, a buffer member 54, a support member 55 and a gasket 56. The buffer guide 51 is a linear bearing. The buffer guide is installed on the frame 10 and is slidably connected to the buffer guide rod 52. The buffer guide rod 52 is connected to the upper pressure platform 40 and reciprocates along the first direction F1. The limit member 53 is connected to one end of the buffer guide rod 52 away from the upper pressure platform 40. The buffer member 54 is a polyurethane buffer member 54.

[0043] When the airbag pressing machine 100 provided by the present application is used: the automobile safety airbag is placed on the lower pressing platform 30, and the lifting driving member 21 of the lifting driving mechanism 20 drives the lower pressing platform 30 to move along the first direction F1, so that the lower pressing platform 30 contacts and squeezes the automobile safety airbag with the upper pressing platform 40, and the lower pressing platform 30 continues to push the upper pressing platform 40 to move along the first direction F1, and the upper pressing platform 40 reduces the instantaneous impact when the lower pressing platform 30 contacts the upper pressing platform 40 through the friction between the buffer guide rod 52 and the buffer member 54 of the buffer mechanism 50, until the upper pressing platform 40 is pressed. The platform 40 contacts the frame 10 and stops moving to achieve the pressing of the automobile airbag. After the pressing of the automobile airbag, the lifting drive member 21 drives the pressing platform 30 to move in the direction opposite to the first direction F1 to achieve the resetting of the pressing platform 30. Under the action of gravity, the upper pressing platform 40 pulls the buffer guide rod 52 to move along the buffer guide member 51, and the limit member 53 contacts the gasket 56 on the buffer member 54, and the buffer member 54 contacts the support member 55 to achieve the resetting of the upper pressing platform 40, and the pressed automobile airbag is taken out to achieve the pressing process of the automobile airbag.
