Description

Technical Field

[0001] The utility model belongs to the technical field of safety airbag production, and in particular relates to a hot air heating and shaping device for airbags. Background Art

[0002] Airbags are a vital component of the airbag system. They are the actuators that protect the occupants.

[0003] When a car collides, the sensor senses the intensity of the collision, and the electronic system receives and processes the sensor's signal. If the electronic control system determines through calculation and analysis that it is necessary to open the airbag, the trigger device will send an ignition signal to trigger the gas generator. After receiving the signal, the gas generator quickly generates a large amount of gas and fills the airbag, so that the occupant comes into contact with a softer energy-absorbing and cushioning object instead of violently colliding with the car's interior. When the human body comes into contact with the airbag, the airbag will absorb the energy of the collision through the throttling damping of the exhaust hole, thereby reducing injuries and protecting the occupants;

[0004] During the production process, the airbag needs to be folded and then assembled. However, after the airbag is folded, it is difficult to fix its shape, which increases the difficulty of assembly and also affects the assembly effect.

[0005] In order to solve the above problems, the present application proposes a hot air heating and shaping device for air bags. Utility Model Content

[0006] In order to solve the above problems existing in the prior art, the utility model provides a hot air heating shaping device for air bags, which is convenient for shaping the air bags during the airbag period and has the characteristics of high shaping efficiency.

[0008] As a preferred technical solution of the utility model, a connecting rod is fixed between the workbench and the fixed plate, and the fixed plate and the workbench are horizontally distributed and fixed in position.

[0009] As an optimal technical solution of the utility model, a guide sleeve is fixedly provided on the fixed plate, and a guide rod is fixedly provided on the upper end of the push plate and slides through the guide sleeve.

[0010] As a preferred technical solution of the utility model, a sliding frame is fixed to one side of the hot air mechanism, a vertical slide rail is fixed to the upper end of the workbench, and the sliding frame slides vertically with the slide rail.

[0012] As a preferred technical solution of the utility model, the pressing profiling member is located directly above the air bag folding profiling member and a cavity for placing and pressing the air bag is provided between the two.

[0022] Specifically, a connecting rod 9 is fixed between the workbench 1 and the fixed plate 2. The fixed plate 2 and the workbench 1 are horizontally distributed and fixed in position. In this embodiment, the connecting rod 9 horizontally supports the fixed plate 2 and the workbench 1 and provides a space for hot air shaping.

[0023] Specifically, a guide sleeve 10 is fixed on the fixed plate 2, and a guide rod 11 is fixed on the upper end of the push plate 4 and slides through the guide sleeve 10. The push plate 4 and the downward pressing profiling member 5 slide vertically and stably between the workbench 1 and the fixed plate 2 through the guide sleeve 10 and the guide rod 11. In this embodiment, the guide sleeve 10 and the guide rod 11 ensure the stability of the vertical sliding of the push plate 4 and the downward pressing profiling member 5 between the workbench 1 and the fixed plate 2, and ensure the reliability of the downward pressing profiling member 5 pressing the airbag tightly in the airbag folding profiling member 6.

[0024] Specifically, a sliding frame 12 is fixed on one side of the hot air mechanism 8, and a vertical slide rail 13 is fixed on the upper end of the workbench 1. The sliding frame 12 and the slide rail 13 slide vertically. In this embodiment, the sliding frame 12 and the slide rail 13 ensure the stability of the servo mechanism 3 driving the hot air mechanism 8 to slide vertically.

[0025] Specifically, a tooling plate 14 is installed at the bottom of the air bag folding profiling member 6, and a movable guide rail mechanism 15 is provided between the workbench 1 and the tooling plate 14. The air bag folding profiling member 6 slides horizontally on the workbench 1 through the movable guide rail mechanism 15.

At this time, the sensor 7 senses whether the air bag is in place. After sensing that it is in place, the servo mechanism 3 drives the push plate 4, the downward pressing profiling member 5, and the hot air mechanism 8 to move downward, and the downward pressing profiling member 5 presses its air bag tightly. The hot air blown out by the hot air mechanism 8 heats the air bag for shaping. When the shaping time is reached, the hot air mechanism 8 stops, and the servo mechanism 3 drives the push plate 4 and the downward pressing profiling member 5 to move upward. At this time, the air bag is cooled and shaped. The shaped air bag is moved out by the movable guide rail mechanism 15, and the shaped air bag is taken out from the air bag folding profiling member 6.
