[0002] An airbag mesh fabric is a key component in an automotive safety system, mainly used inside an airbag frame, which can ensure the smooth deployment of the airbag in case of an emergency and protect the safety of passengers. The airbag mesh fabric is a yellow mesh fabric, mainly used to connect the airbag frame, usually made of aramid and polyester, and has excellent strength performance and stability.

[0003] During the production process of the airbag mesh fabric, traditional methods mainly rely on manual operations for folding and sewing. However, manual operations have problems such as low efficiency and insufficient folding accuracy. When folding manually, the folding method is prone to deviation, resulting in inaccurate folding positions of the airbag mesh fabric. The same problem exists in manual sewing. Moreover, the folding and sewing processes are separated and require the cooperation of multiple devices, which makes the process conversion time long. Manual transfer of the airbag mesh fabric also takes a lot of time, and the material is prone to displacement, thus resulting in low efficiency during mass production. Summary of the Invention

[0014] Preferably, a method for using an automatic folding, fixing and sewing integrated device for the airbag mesh fabric functional area includes the following steps: S1. Placement and positioning of the airbag mesh fabric: Lay the airbag mesh fabric to be processed flat on the airbag mesh fabric placement board. Control the synchronous adjustment board to rise through the mating plug board separation driving mechanism, so that the airbag mesh fabric positioning block extends out of the positioning block movable opening to accurately position the airbag mesh fabric. Subsequently, the mating plug board is separated from the airbag mesh fabric placement board through the mating plug board connecting frame to reserve space for the folding operation; S2. Pressing down of the folding unit and preliminary folding: Start the lifting unit, and the first servo cylinder drives the folding unit connecting frame to descend, driving the whole folding unit to move downward; the airbag mesh fabric plug board contacts both sides of the airbag mesh fabric, and the second cylinder drives the plug board pushing mechanism to make the airbag mesh fabric plug boards on both sides move closer to the middle synchronously, pressing the cloth bodies on both sides of the airbag mesh fabric under the plug board head to form a preliminary crease; at the same time, the first cylinder drives the airbag mesh fabric pressing plate to press down to fix the position of the airbag mesh fabric; S3. Folding assist mechanism cooperates with pressing: When the airbag net fabric insertion plate is inserted below the insertion plate head, the third cylinder contracts, driving the entire folding assist mechanism to descend, so that the folded airbag net fabric is tightly pressed and shaped. After folding, the first cylinder contracts to lift the airbag net fabric pressing plate, and the folding unit resets to the initial height. The airbag net fabric insertion plate vertically withdraws to avoid pulling the net fabric. S4. Transfer the airbag net fabric to the sewing station: Control the transverse electric slide rail mechanism and the longitudinal electric slide rail mechanism through the airbag net fabric transfer plate drive mechanism to move the airbag net fabric transfer plate above the folding assist mechanism. The second servo electric cylinder drives the transfer plate connecting frame to descend, so that the airbag net fabric transfer plate presses the folded airbag net fabric. Cooperate with the insertion plate to synchronously contract to the side of the airbag net fabric placement plate, and the folding assist mechanism descends to be flush with the mirror panel to ensure the stability of the folded state during the transfer process. S5. Automatic sewing and reset: The airbag net fabric transfer plate carries the folded airbag net fabric and slides along the mirror panel to below the sewing machine, and the sewing opening is aligned with the folding joint. The sewing machine automatically stitches the folding part. After stitching, the airbag net fabric transfer plate resets to the initial position, and the cooperation insertion plate separation drive mechanism is controlled to separate the cooperation insertion plate to prepare for the next cycle operation.

[0033] Moreover, on the inner bottom wall of the operation table 01, on one side of the mating plate drive unit mounting seat 015, an airbag fabric transfer plate drive mechanism 06 is provided; the airbag fabric transfer plate drive mechanism 06 includes a horizontal electric slide rail mechanism 061. A vertical electric slide rail mechanism 062 is horizontally slidably engaged with the horizontal electric slide rail mechanism 061. A transfer plate drive mechanism 2 is vertically slidably engaged with the vertical electric slide rail mechanism 062. The transfer plate drive mechanism 2 is used to control the height of the airbag fabric transfer plate 1.

[0034] In addition, the transfer plate driving mechanism 2 includes a guide rail mechanism mounting bracket 21. On the guide rail mechanism mounting bracket 21, fourth guide rail mechanisms 22 are symmetrically arranged. The fourth guide rail mechanism 22 is composed of a slider and a guide rail. A second servo cylinder 23 is vertically arranged between the fourth guide rail mechanisms 22 on both sides of the guide rail mechanism mounting bracket 21. The top end of the piston rod of the output end of the second servo cylinder 23 is assembled and connected with a transfer plate connecting frame 24. The transfer plate connecting frame 24 is installed on the fourth guide rail mechanisms 22 on both sides. The second servo cylinder 23 realizes precise control to synchronously adjust the height of the lifting of the synchronous adjustment plate 62.

[0035] Moreover, at the bottom of the other side of the transfer plate connecting frame 24 away from the fourth guide rail mechanism 22, an airbag fabric transfer plate 1 is installed. The airbag fabric transfer plate 1 is used to transfer the airbag fabric from the folding auxiliary mechanism 03 to below the sewing machine 04. Sewing openings 11 are symmetrically formed on the airbag fabric transfer plate 1. Chamfered portions 12 are formed on the side edges of the sewing openings 11. At the bottom surface of the airbag fabric transfer plate 1 and on both sides of the sewing openings 11, a plurality of bumps 13 are arranged horizontally. The bumps 13 increase the contact area with the airbag fabric, enabling better driving of the airbag fabric during transfer.

[0036] A method for using an automatic folding, fixing and sewing integrated device for an airbag fabric functional area includes the following steps: S1. Placement and positioning of the airbag fabric: Lay the airbag fabric to be processed flat on the airbag fabric placement plate 031. Control the synchronous adjustment plate 62 to rise through the cooperation of the plug board separation driving mechanism 6, so that the airbag fabric positioning block 631 extends out of the positioning block moving opening 0311 to accurately position the airbag fabric. Subsequently, cooperate with the plug board 032 to separate from the airbag fabric placement plate 031 through the cooperation of the plug board connecting frame 7 to reserve space for the folding operation; S2. Pressing down of the folding unit and preliminary folding: Start the lifting unit 02. The first servo cylinder 023 drives the folding unit connecting frame 024 to descend, driving the entire folding unit 05 to move downward; the airbag fabric plug boards 054 contact both sides of the airbag fabric. The second cylinder 0533 drives the plug board pushing mechanism 053 to make the airbag fabric plug boards 054 on both sides move closer to the middle synchronously, pressing the fabric bodies on both sides of the airbag fabric under the plug board head 0321 to form a preliminary crease; at the same time, the first cylinder 0521 drives the airbag fabric pressing plate 055 to press down to fix the position of the airbag fabric; S3. Cooperation and pressing of the folding auxiliary mechanism: When the airbag fabric plug boards 054 are inserted under the plug board head 0321, the third cylinder 4 contracts, driving the entire folding auxiliary mechanism 03 to descend, pressing and shaping the folded airbag fabric tightly; after folding, the first cylinder 0521 contracts to lift the airbag fabric pressing plate 055, and the folding unit 05 resets to the initial height. The airbag fabric plug boards 054 withdraw vertically to avoid pulling the fabric; S4. Transfer the airbag mesh fabric to the sewing station: Control the horizontal electric slide rail mechanism 061 and the vertical electric slide rail mechanism 062 through the driving mechanism 06 of the airbag mesh fabric transfer board, and move the airbag mesh fabric transfer board 1 above the folding assistance mechanism 03; The second servo cylinder 23 drives the connecting frame 24 of the transfer board to descend, so that the airbag mesh fabric transfer board 1 presses the folded airbag mesh fabric; The matching plug board 032 is synchronously retracted to the side of the airbag mesh fabric placement board 031, and the folding assistance mechanism 03 descends to be flush with the mirror panel 013 to ensure the stability of the folded state during the transfer process. S5. Automatic sewing and reset: The airbag mesh fabric transfer board 1 carries the folded airbag mesh fabric and slides along the mirror panel 013 to the lower part of the sewing machine 04, and the sewing opening 11 is aligned with the folding joint; The sewing machine 04 automatically stitches the folded part; After sewing is completed, the airbag mesh fabric transfer board 1 resets to the initial position, and the matching plug board separation driving mechanism 6 controls the separation of the matching plug board 032 to prepare for the next cycle of operation.

[0037] In this embodiment, when folding the airbag mesh fabric, place the airbag mesh fabric on the airbag mesh fabric placement board 031 and accurately position it through the airbag mesh fabric positioning block 631. At this time, the folding assistance mechanism 03 is located above the horizontal plane of the mirror panel 013, and the matching plug boards 032 on both sides are separated from the airbag mesh fabric placement board 031. After the airbag mesh fabric is placed, the automatic folding work can start. First, the lifting unit 02 works, and the piston rod of the first servo cylinder 023 automatically extends downward, realizing the automatic downward sliding of the folding unit connecting frame 024 and the lowering of the height of the folding unit 05. At this time, the airbag mesh fabric plug board 054 will first contact the surface of the airbag mesh fabric, and the airbag mesh fabric plug board 054 will press down the two side cloth bodies of the airbag mesh fabric that are not in contact with the folding assistance mechanism 03, so that the two sides of the cloth body are bent under the downward pressure of the airbag mesh fabric plug board 054 at the plug board head 0321.

[0038] While the airbag mesh board 054 is being 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 the airbag mesh placed below. While the airbag mesh pressing plate 055 presses the airbag mesh, the second cylinders 0533 on both sides work synchronously, and the piston rods of the second cylinders 0533 contract synchronously, causing the plugboard connecting frames 0531 on both sides to approach each other, thus realizing the simultaneous approach of the airbag mesh plugboards 054 on both sides. The airbag mesh plugboards 054 are respectively inserted under the plugboard heads 0321 on both sides. During this process, the airbag mesh plugboards 054 fold the airbag mesh at the plugboard heads 0321. And during the process of the folding unit 05 pressing down for folding, the piston rod of the third cylinder 4 contracts a certain distance to ensure that when the airbag mesh plugboards 054 are inserted under the plugboard heads 0321, they descend a certain distance along with the entire folding auxiliary mechanism 03, ensuring a tighter fold. After the airbag mesh plugboards 054 are withdrawn, the folding auxiliary mechanism 03 rises again to leave space for the airbag mesh plugboards 054 to retract.

[0039] After the airbag mesh plugboards 054 on both sides approach each other and fold the airbag mesh, the piston rod of the first cylinder 0521 first contracts to lift the airbag mesh pressing plate 055. After the airbag mesh pressing plate 055 is lifted, the folding unit 05 descends a certain distance to ensure that the airbag mesh plugboards 054 are vertically pushed out and separated from the airbag mesh, preventing the airbag mesh from being carried out when pushed horizontally. After the airbag mesh plugboards 054 are reset, the lifting unit 02 controls the folding unit 05 to lift and restore the folding unit 05 to its initial position.

[0040] After the airbag mesh is folded by the folding unit 05 and the folding auxiliary mechanism 03, at this time, the folded airbag mesh is transferred to the lower part of the sewing machine 04 for sewing through the airbag mesh transfer plate 1.

[0041] Driven by the horizontal electric slide rail mechanism 061 and the vertical electric slide rail mechanism 062, the airbag mesh transfer plate 1 is moved to directly above the folding assistance mechanism 03. At this time, the transfer plate driving mechanism 2 controls the airbag mesh transfer plate 1 to descend. The second servo electric cylinder 23 controls the piston rod to contract, 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 on the airbag mesh on the folding assistance mechanism 03. While the airbag mesh transfer plate 1 presses on the airbag mesh, the mating plug plates 032 on both sides contract simultaneously and move closer to the airbag mesh placement plate 031 in the middle, so that the plug heads 0321 disengage from the gaps of the folded airbag mesh. And while disengaging, the airbag mesh transfer plate 1 tightly presses on the airbag mesh synchronously. And the third cylinder 4 drives the folding assistance mechanism 03 to descend synchronously. The folding assistance mechanism 03 descends to the same plane as the mirror panel 013. The airbag mesh transfer plate 1 completely presses on the airbag mesh and ensures its folded state. The folding joints on both sides of the airbag mesh are both located at the sewing openings 11 on both sides.

[0042] After the airbag mesh transfer plate 1 presses on the airbag mesh, it carries and transfers the airbag mesh. The airbag mesh transfer plate driving mechanism 06 controls the airbag mesh transfer plate 1 to displace to below the sewing machine 04. During this process, the airbag mesh transfer plate 1 presses on the airbag mesh and slides on the smooth mirror panel 013. And after being transferred to below the sewing machine 04, the airbag mesh transfer plate driving mechanism 06 controls the displacement of the airbag mesh transfer plate 1 so that the sewing machine 04 can sew the folding joints of the airbag mesh at the sewing openings 11. In this way, the automatic folding, automatic transfer, and automatic sewing of the airbag mesh are completed.

[0043] When controlling the overall lifting and lowering of the folding assistance mechanism 03 at the movable opening 014, the third cylinder 4 drives the mating plate mounting main frame 5 to move vertically on the fifth guide rail mechanisms 3 on both sides. When controlling the synchronous separation and approach of the mating plug plates 032 on both sides of the airbag mesh placement plate 031, it is driven by the mating plug plate separation driving mechanism 6. When the mating plug plates 032 separate, the piston rod of the third servo electric cylinder 61 extends upward to drive the synchronous adjustment plate 62 to rise. As the synchronous adjustment plate 62 rises, the position of the limit chute 621 changes, so that the single-rod bearing 76 is restricted by the limit chute 621, thereby driving the mating plug plate sliders 71 on both sides to separate from each other on the mating plug plate connecting frame guide rail 51 at the same time, so that the mating plug plates 032 connected above are separated from the airbag mesh placement plate 031 at the same time, facilitating the folding of the airbag mesh. When the mating plug plates 032 contract and move closer to the airbag mesh placement plate 031, the synchronous adjustment plate 62 descends.

[0044] While the synchronous adjustment plate 62 is rising, the airbag mesh positioning block 631 rises and extends from the positioning block movable opening 0311, facilitating the placement of the airbag mesh. When the airbag mesh needs to be transferred after being folded, the airbag mesh positioning block 631 will retract from the positioning block movable opening 0311 as the synchronous adjustment plate 62 descends, ensuring that it does not protrude and is on the same plane as the airbag mesh placement plate 031.

[0045] In the present invention, the device integrates the functions of folding, fixing, and sewing into a single device, reducing the process conversion time. The folding position is ensured to be accurate through the airbag mesh positioning block 631, and the airbag mesh is automatically folded through the folding unit 05 and the folding auxiliary mechanism 03. The mirror panel 013 and the airbag mesh transfer plate 1 are designed in cooperation, and the friction is increased by the convex block 13 to achieve the stable and rapid transfer of the folded mesh, avoiding material displacement or damage. The overall device adopts a fully automated process to reduce manual intervention, lower the unit production cost, and is more efficient and of higher quality than manual labor during mass production.

[0046] The above is only a preferred specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution and inventive concept of the present invention, making equivalent substitutions or changes should be covered within the protection scope of the present invention.
