Description

Technical Field

[0002] Airbag mesh is a key component in automotive safety systems, primarily used within the airbag frame to ensure smooth airbag deployment in emergencies and protect passenger safety. Airbag mesh is a yellow mesh fabric mainly used to connect the airbag frame. It is typically made of aramid and polyester, possessing excellent strength and stability.

[0003] In the production process of airbag mesh, the traditional method is manual folding and sewing. However, manual folding is prone to deviation, resulting in inaccurate folding position of the airbag mesh. Manual sewing has the same problem. Furthermore, the folding and sewing processes are separate, requiring the cooperation of multiple machines, which makes the process changeover time long. Manual transfer of airbag mesh also takes a lot of time, and the material is prone to displacement, resulting in low efficiency in mass production. Utility Model Content

[0064] Furthermore, the transfer plate drive mechanism 2 includes a guide rail mechanism mounting frame 21, on which a fourth guide rail mechanism 22 is symmetrically arranged.

[0066] The third cylinder 3 is symmetrically arranged on the mounting base 015 of the drive unit of the mating plate. The piston rod end of the top of the third cylinder 3 is horizontally connected to the folding auxiliary mechanism mounting plate 4. The upper surface of the folding auxiliary mechanism mounting plate 4 is vertically arranged in the middle of the airbag mesh placement plate connecting frame 5. The top of the airbag mesh placement plate connecting frame 5 is provided with an airbag mesh placement plate connecting plate 51. The airbag mesh placement plate 031 is installed on the upper surface of the airbag mesh placement plate connecting plate 51, and the airbag mesh placement plate connecting plate 51 plays a connecting role.

[0067] Meanwhile, the folding auxiliary mechanism mounting plate 4 is symmetrically provided with sliding rod guide frames 41 on the left and right sides of the airbag mesh placement plate connecting frame 5. The sliding rod guide frames 41 are symmetrically and slidably provided with mating insert connecting plates 7. The folding auxiliary mechanism mounting plate 4 is symmetrically provided with electric cylinder mounting plates 42 on the front and rear sides of the airbag mesh placement plate connecting frame 5. The sliding rod guide frames 41 are used to guide the mating insert connecting plates 7.

[0068] In addition, a third servo electric cylinder 6 is installed on the electric cylinder mounting plate 42. The piston rod end of the output end of the third servo electric cylinder 6 is assembled and connected to the mating insert plate connecting plate 7. Multiple mating insert plate mounting holes 72 are evenly arranged in the horizontal direction on the top of the mating insert plate connecting plate 7. The mating insert plate mounting holes 72 are used to install mating insert plates 032. Sliding holes 71 are symmetrically opened on the mating insert plate connecting plate 7. The sliding holes 71 are used to fit on the slide rod guide frame 41.

[0069] In this embodiment, when folding the airbag mesh, the airbag mesh is placed on the airbag mesh placement plate 031. At this time, the folding auxiliary mechanism 03 is located above the horizontal plane of the mirror panel 013, and the mating inserts 032 on both sides are separated from the airbag mesh placement plate 031. After the airbag mesh is placed, the automatic folding operation can begin. First, the lifting unit 02 operates, and the piston rod of the first servo cylinder 023 automatically extends downward, realizing that the folding unit connecting frame 024 automatically slides downward, and the height of the folding unit 05 decreases. At this time, the airbag mesh insert 054 will first contact the surface of the airbag mesh, and the airbag mesh insert 054 will press down the two sides of the airbag mesh that are not in contact with the folding auxiliary mechanism 03, so that the two sides of the fabric are bent by the downward pressure of the airbag mesh insert 054 at the insert head 0321.

[0070] As the airbag mesh insert plate 054 is pressed down, the piston rod of the first cylinder 0521 extends downward, driving the cylinder connecting plate 0523 to press down, so that the airbag mesh pressing plate 055 can press down on the airbag mesh placed below. While the airbag mesh pressing plate 055 presses down on the airbag mesh, the second cylinders 0533 on both sides work synchronously, and the piston rods of the second cylinders 0533 retract synchronously, causing the insert plate connecting frames 0531 on both sides to move closer to each other, thereby realizing that the airbag mesh insert plates 054 on both sides move closer together at the same time, and the airbag mesh insert plates 054 are respectively inserted into the two Below the side insert head 0321, during this process, the airbag mesh insert plate 054 folds the airbag mesh at the insert head 0321. While the folding unit 05 is pressing down to fold, the piston rod of the third cylinder 3 retracts a certain distance to ensure that when the airbag mesh insert plate 054 is inserted below the insert head 0321, it descends a certain distance along with the folding auxiliary mechanism 03 to ensure a tighter fold. After the airbag mesh insert plate 054 is removed, the folding auxiliary mechanism 03 rises again to allow space for the airbag mesh insert plate 054 to retract.

[0071] When the airbag mesh insert plates 054 on both sides approach each other and fold the airbag mesh, the piston rod of the first cylinder 0521 retracts first, lifting the airbag mesh pressure plate 055. After the airbag mesh pressure plate 055 is lifted, the folding unit 05 descends a certain distance to ensure that the airbag mesh insert plate 054 is pushed out vertically and separated from the airbag mesh, preventing the airbag mesh from being pulled out when pushed out laterally. After the airbag mesh insert plate 054 is reset, the lifting unit 02 controls the folding unit 05 to lift up and restore the folding unit 05 to its initial position.

[0072] After the airbag mesh is folded by the folding unit 05 and the folding auxiliary mechanism 03, the folded airbag mesh is transferred to the sewing machine 04 for sewing via the airbag mesh transfer plate 1.

[0073] Driven by the transverse electric slide rail mechanism 061 and the longitudinal electric slide rail mechanism 062, the airbag mesh transfer plate 1 is moved to directly above the folding auxiliary mechanism 03. At this time, the transfer plate drive mechanism 2 controls the airbag mesh transfer plate 1 to descend, the second servo cylinder 23 controls the piston rod to retract, and the transfer plate connecting frame 24 descends on the fourth guide rail mechanism 22. The airbag mesh transfer plate 1 descends until it presses down on the airbag mesh on the folding auxiliary mechanism 03. At the same time that the airbag mesh transfer plate 1 presses down on the airbag mesh, the mating inserts 03 on both sides... 2. Simultaneously, the airbag mesh placement plate 031 is retracted and pressed tightly against the middle, so that the insert head 0321 is disengaged from the gap of the folded airbag mesh. At the same time as disengagement, the airbag mesh transfer plate 1 presses the airbag mesh tightly, and the third cylinder 3 drives the folding auxiliary mechanism 03 to descend synchronously. The folding auxiliary mechanism 03 descends to the same surface as the mirror panel 013. The airbag mesh transfer plate 1 completely presses down the airbag mesh and ensures its folded state. The folding junctions on both sides of the airbag mesh are located at the sewing openings 11 on both sides.

[0074] After the airbag mesh transfer plate 1 presses down on the airbag mesh, it is transported and transferred. The airbag mesh transfer plate drive mechanism 06 controls the airbag mesh transfer plate 1 to move to the bottom of the sewing machine 04. During this process, the airbag mesh transfer plate 1 presses down on the airbag mesh and slides on the smooth mirror panel 013. After being transferred to the bottom of the sewing machine 04, the airbag mesh transfer plate drive mechanism 06 controls the airbag mesh transfer plate 1 to move, so that the sewing machine 04 can sew the folded joint of the airbag mesh at the sewing opening 11. This completes the automatic folding, automatic transfer and automatic sewing of the airbag mesh.

[0075] When the folding auxiliary mechanism 03 is raised and lowered at the movable opening 014, the piston rod of the third cylinder 3 extends and retracts to drive the mounting plate 4 of the folding auxiliary mechanism to move up and down, thereby realizing the raising and lowering of the folding auxiliary mechanism 03. When the mating inserts 032 on both sides of the airbag mesh placement plate 031 are synchronously separated and brought closer together, the piston rods of the third servo cylinders 6 on both sides retract simultaneously, driving the mating insert connecting plates 7 on both sides to move synchronously on the slide guide frame 41, and synchronously approaching and separating on both sides of the airbag mesh placement plate 031.

[0076] In this practical application, the device integrates folding, fixing and sewing functions into a single device, reducing process changeover time. The folding unit 05 and the folding auxiliary mechanism 03 realize automatic folding of the airbag mesh fabric. The design of the airbag mesh fabric transfer plate 1 realizes the smooth and rapid transfer of the folded mesh fabric, avoiding material displacement or damage.
