Manufacturing method and system for airbag

A system for manufacturing an airbag, the manufacturing system comprising:

• an inner mold;
• a model creating unit configured to create a 3D printing model;
• a nozzle setting unit configured to determine the number of 3D printing nozzles and a positional relationship between each 3D printing nozzle and the inner mold according to the 3D printing model, and to assign a printing task to each 3D printing nozzle;
• an execution unit configured to control each 3D printing nozzle to execute a respective printing task on an outer surface of the inner mold so as to form a ply on the outer surface of the inner mold, and to remove the 3D printing nozzles after all printing tasks are completed;
• and
• a demolding unit configured to remove the inner mold so as to remove the ply from the outer surface of the inner mold.

A method for manufacturing an airbag, the manufacturing method comprising the following steps:

• S1:
• creating a 3D printing model, and providing an outer mold provided with an opening and a hollow portion;
• S2:
• determining the number of 3D printing nozzles and a starting position of each 3D printing nozzle in the hollow portion according to the 3D printing model, and assigning a printing task to each 3D printing nozzle;
• S3:
• controlling each 3D printing nozzle to enter the hollow portion through the opening to reach a respective starting position, and to execute a respective printing task on an inner surface of the outer mold from the respective starting position so as to form a ply on the inner surface of the outer mold;
• and
• S4:
• removing the 3D printing nozzles through the opening after the printing tasks are completed, and removing the ply from the inner surface of the outer mold and taking the ply out through the opening.
