Description

Technical Field

[0001] The invention relates to the technical field of sewing machines, in particular to a template assembly used on a pattern sewing machine. Background Art

[0002] The airbag system is a passive safety protection system. It is used in conjunction with seat belts to provide effective anti-collision protection for passengers. When a car collides, the car airbag (airbag bag) can reduce the head injury rate by 25% and the facial injury rate by about 80%. The head airbag is also called the side airbag. When a collision occurs, it pops up to cover the B-pillar side, window glass, and the side support buckle of the seat belt, which are easy to cause collision injuries to the human body, and separates the driver and passengers from these things to achieve the effect of protecting the driver and passengers. The side airbag is long, has a large sewing area, and has complex sewing stitches. It is usually sewn using a large pattern machine. The existing pattern machine usually includes a workbench mechanism and a sewing mechanism set on the workbench mechanism, as well as an X-direction and Y-direction drive mechanism for driving the sewing template. The sewing mechanism includes a sewing machine head and a lock core changing mechanism, which is already a mature technology. Each equipment manufacturer usually purchases a ready-made sewing mechanism, and then designs the corresponding workbench mechanism and X-direction and Y-direction drive mechanism according to the size of the travel range. The template assembly is connected to the corresponding template quick-install assembly on the pattern machine through the corresponding connector. When sewing, the sewing machine head does not move, and the X-axis and Y-axis driving mechanism drives the template assembly to move on the workbench mechanism according to the sewing stitches through the template quick-install assembly. When the sewing mechanism sews the airbag bag, usually after one sewing is completed, the template assembly is removed, the sewn airbag bag is taken out from the template assembly, and then the next airbag bag to be sewn is placed in the template assembly, and after it is fixed, the template assembly is placed on the pattern machine for sewing.
