Description

Technical Field

[0001] The present invention relates to the technical field of airbag mesh processing, and in particular to a device and method for automatically folding, fixing, and sewing functional areas of an airbag mesh. Background Art

[0002] Airbag mesh is a key component in automotive safety systems. It's primarily used within the airbag frame, ensuring smooth deployment and protecting passengers in emergencies. Airbag mesh is a yellow mesh fabric that connects the airbag frame. It's typically made of aramid and polyester, offering excellent strength and stability.

[0003] In the production process of airbag mesh, traditional methods mainly rely on manual folding and sewing operations. However, manual operation has problems such as low efficiency and insufficient folding precision. The manual folding method is prone to deviation during folding, resulting in inaccurate folding position of the airbag mesh. Manual sewing also has the same problem. In addition, 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 also takes a lot of time, and the material is easily shifted, resulting in low efficiency in mass production. Summary of the Invention

[0028] Preferably, a method for using a device for automatically folding, fixing, and sewing the functional area of an airbag mesh comprises the following steps:

[0029] S1. Airbag mesh placement and positioning: The airbag mesh to be processed is laid flat on the airbag mesh placement plate. The synchronous adjustment plate is controlled to rise by the mating plate separation drive mechanism, so that the airbag mesh positioning block extends from the positioning block movable opening to accurately position the airbag mesh. Subsequently, the mating plate is separated from the airbag mesh placement plate by the mating plate connecting frame to reserve space for the folding operation.

[0030] S2. Pressing down the folding unit and preliminary folding: Start the lifting unit, and the first servo electric cylinder drives the folding unit connecting frame to descend, driving the folding unit to move downward as a whole; the airbag mesh inserting plate contacts the two sides of the airbag mesh, and the second cylinder drives the inserting plate pushing mechanism to make the airbag mesh inserting plates on both sides move together in the middle, pressing the airbag mesh fabric under the inserting plate head to form preliminary folds; at the same time, the first cylinder drives the airbag mesh pressing plate to press down to fix the airbag mesh in position;

[0031] S3. Folding auxiliary mechanism cooperates with pressing: When the airbag mesh insert is inserted under the insert head, the third cylinder contracts, driving the folding auxiliary mechanism to descend as a whole, so that the folded airbag mesh is pressed and shaped; after folding is completed, the first cylinder contracts and lifts the airbag mesh pressing plate, the folding unit returns to its initial height, and the airbag mesh insert is vertically withdrawn to avoid pulling the mesh;

[0032] S4. Transferring the airbag mesh to the sewing station: The airbag mesh transfer plate driving mechanism controls the transverse electric slide mechanism and the longitudinal electric slide mechanism to move the airbag mesh transfer plate above the folding auxiliary mechanism. The second servo electric cylinder drives the transfer plate connecting frame to descend, so that the airbag mesh transfer plate presses the folded airbag mesh tightly. The insert plate is synchronously retracted to the side of the airbag mesh placement plate, and the folding auxiliary mechanism is lowered to be flush with the mirror plate to ensure a stable folding state during the transfer process.

[0033] S5. Automatic sewing and resetting: The airbag mesh cloth transfer plate carries the folded airbag mesh cloth and slides along the mirror plate to the bottom of the sewing machine, with the sewing opening aligned with the folded junction; the sewing machine automatically sews the folded part; after sewing is completed, the airbag mesh cloth transfer plate is reset to the initial position, and the plug-in plate separation drive mechanism is controlled to separate the plug-in plate, preparing for the next cycle operation.

[0034] The beneficial effects of the present invention are: in the present invention, the device integrates the folding, fixing and sewing functions into a single device, reducing the process conversion time, ensuring the accuracy of the folding position through the airbag mesh positioning block, and automatically folding the airbag mesh through the folding unit and the folding auxiliary mechanism. The mirror panel and the airbag mesh transfer plate are designed to cooperate with each other, and the convex blocks are combined to increase the friction force, so as to achieve smooth and fast transfer of the mesh after folding, avoiding material displacement or damage. The overall device adopts a fully automated process to reduce manual intervention, reduce unit production costs, and is more efficient and high-quality than manual production in mass production.

The airbag mesh positioning block 631 is used for precise positioning of the airbag mesh.

[0076] At the same time, the airbag mesh placement plate connecting frame 8 includes a connecting rod 82, which is symmetrically and vertically fixedly connected to the matching plate mounting main frame 5. The top of the connecting rod 82 is horizontally fixedly connected to the placement plate connecting plate 81. The airbag mesh placement plate 031 is used to be installed on the upper surface of the placement plate connecting plate 81, and the placement plate connecting plate 81 is used to connect the airbag mesh placement plate 031.

[0077] Moreover, an airbag mesh transfer plate driving mechanism 06 is provided on the inner bottom wall of the operating table 01, located on one side of the matching plate driving unit mounting seat 015; the airbag mesh transfer plate driving mechanism 06 includes a transverse electric slide rail mechanism 061, and the transverse electric slide rail mechanism 061 is laterally slidably matched with a longitudinal electric slide rail mechanism 062, and the longitudinal electric slide rail mechanism 062 is longitudinally slidably matched with a transfer plate driving mechanism 2, and the transfer plate driving mechanism 2 is used to control the height of the airbag mesh transfer plate 1.

A plurality of protrusions 13 are provided on the bottom surface of the airbag mesh transfer plate 1 and on both sides of the sewing openings 11 in a horizontal arrangement. The protrusions 13 increase the contact area with the airbag mesh, so that the airbag mesh can be better driven to transfer during transfer.

[0080] A method for using a device for automatically folding, fixing, and sewing functional areas of an airbag mesh fabric comprises the following steps:

[0081] S1. Airbag mesh placement and positioning: The airbag mesh to be processed is laid flat on the airbag mesh placement plate 031. The synchronous adjustment plate 62 is controlled to rise by the mating plate separation drive mechanism 6, so that the airbag mesh positioning block 631 extends from the positioning block movable opening 0311 to accurately position the airbag mesh. Subsequently, the mating plate 032 is separated from the airbag mesh placement plate 031 by the mating plate connecting frame 7 to reserve space for the folding operation.

[0082] S2. Pressing down the folding unit and preliminary folding: Start the lifting unit 02, and the first servo electric cylinder 023 drives the folding unit connecting frame 024 to descend, driving the folding unit 05 to move downward as a whole; the airbag mesh inserting plate 054 contacts the two sides of the airbag mesh, and the second cylinder 0533 drives the inserting plate pushing mechanism 053 to make the airbag mesh inserting plates 054 on both sides move toward the middle synchronously, pressing the fabric on both sides of the airbag mesh under the inserting plate head 0321 to form preliminary folds; at the same time, the first cylinder 0521 drives the airbag mesh pressing plate 055 to press down to fix the position of the airbag mesh;

[0083] S3. Folding auxiliary mechanism cooperates with pressing: When the airbag mesh insert 054 is inserted under the insert head 0321, the third cylinder 4 contracts, driving the folding auxiliary mechanism 03 to descend as a whole, so that the folded airbag mesh is pressed and shaped; after folding is completed, the first cylinder 0521 contracts and lifts the airbag mesh pressing plate 055, the folding unit 05 returns to its initial height, and the airbag mesh insert 054 is vertically withdrawn to avoid pulling the mesh;

[0084] S4. Transfer the airbag mesh to the sewing station: The airbag mesh transfer plate driving mechanism 06 controls the transverse electric slide mechanism 061 and the longitudinal electric slide mechanism 062 to move the airbag mesh transfer plate 1 above the folding auxiliary mechanism 03; the second servo electric cylinder 23 drives the transfer plate connecting frame 24 to descend, so that the airbag mesh transfer plate 1 presses the folded airbag mesh; the insert plate 032 is synchronously retracted to the side of the airbag mesh placement plate 031, and the folding auxiliary mechanism 03 is lowered to be flush with the mirror plate 013 to ensure a stable folding state during the transfer process;

[0085] S5. Automatic sewing and resetting: The airbag mesh transfer plate 1 carries the folded airbag mesh and slides along the mirror plate 013 to the bottom of the sewing machine 04, and the sewing port 11 is aligned with the folded junction; the sewing machine 04 automatically sews the folded part; after the sewing is completed, the airbag mesh transfer plate 1 is reset to the initial position, and the plug-in plate separation drive mechanism 6 controls the plug-in plate 032 to separate, preparing for the next cycle operation.

[0086] In this embodiment, when folding the airbag mesh, the airbag mesh is placed on the airbag mesh placement plate 031 and is precisely positioned by the airbag mesh positioning block 631. At this time, the folding auxiliary mechanism 03 is located above the horizontal plane of the mirror panel 013, and the matching plug plates 032 on both sides are separated from the airbag mesh placement plate 031. After the airbag mesh is placed, the automatic folding work can be started. First, the lifting unit 02 works, and the piston rod of the first servo electric cylinder 023 automatically extends downward to realize the automatic downward sliding of the folding unit connecting frame 024, and the height of the folding unit 05 is reduced. At this time, the airbag mesh plug plate 054 will first contact the surface of the airbag mesh, and the airbag mesh plug plate 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 cloth body are bent at the plug plate head 0321 by the downward pressure of the airbag mesh plug plate 054.

[0087] When 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 the airbag mesh placed below. When 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, so that the insert plate connecting frames 0531 on both sides are close to each other, thereby realizing that the airbag mesh insert plates 054 on both sides are close to each other at the same time, and the airbag mesh insert plates 054 are respectively inserted into the two Under the plug head 0321 on the side, during this process, the airbag mesh plug plate 054 folds the airbag mesh at the plug plate head 0321, and in the process of the folding unit 05 pressing down to fold, the piston rod of the third cylinder 4 contracts a distance to ensure that the airbag mesh plug plate 054 is inserted under the plug plate head 0321. As the folding auxiliary mechanism 03 descends a distance, it is ensured that the folding is tighter. After the airbag mesh plug plate 054 withdraws, the folding auxiliary mechanism 03 rises again to leave space for the airbag mesh plug plate 054 to retreat.

[0088] When the airbag mesh inserts 054 on both sides are close to each other and the airbag mesh is folded, the piston rod of the first cylinder 0521 contracts first to lift 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 054 is pushed out vertically and separated from the airbag mesh to prevent the airbag mesh from being brought out when pushed out horizontally. After the airbag mesh insert 054 is reset, the lifting unit 02 controls the folding unit 05 to lift and restore the folding unit 05 to its initial position.

[0089] 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 bottom of the sewing machine 04 by the airbag mesh transfer plate 1 for sewing.

[0090] Driven by the horizontal electric slide mechanism 061 and the longitudinal electric slide mechanism 062, the airbag mesh transfer plate 1 is moved to the top of the folding auxiliary mechanism 03. At this time, the transfer plate driving mechanism 2 controls the airbag mesh transfer plate 1 to descend, and the second servo electric cylinder 23 controls the piston rod to retract. The transfer plate connecting frame 24 descends on the fourth guide rail mechanism 22. The airbag mesh transfer plate 1 descends until it presses the airbag mesh on the folding auxiliary mechanism 03. While the airbag mesh transfer plate 1 presses the airbag mesh, the matching plug plates 03 on both sides 2 and simultaneously shrink and press against the middle airbag mesh placement plate 031, so that the plug head 0321 is separated from the folded gap of the airbag mesh. At the same time, the airbag mesh transfer plate 1 presses the airbag mesh tightly, and the third cylinder 4 drives the folding auxiliary mechanism 03 to descend synchronously. The folding auxiliary mechanism 03 descends to the same surface as the mirror plate 013. The airbag mesh transfer plate 1 completely presses the airbag mesh and ensures its folded state. The folded junctions on both sides of the airbag mesh are located at the sewing openings 11 on both sides.

[0091] After the airbag mesh transfer plate 1 presses the airbag mesh, the airbag mesh is transported and transferred, and the airbag mesh transfer plate driving 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 the airbag mesh and slides on the smooth mirror panel 013, and after being transferred to the bottom of the sewing machine 04, the airbag mesh transfer plate driving mechanism 06 controls the airbag mesh transfer plate 1 to move, so that the sewing machine 04 can sew the folded junction of the airbag mesh at the sewing mouth 11, thereby completing the automatic folding, automatic transfer, and automatic sewing of the airbag mesh.

[0092] When the folding auxiliary mechanism 03 is controlled to rise and fall at the movable opening 014 as a whole, the third cylinder 4 drives the matching plate mounting main frame 5 to move vertically on the fifth guide rail mechanism 3 on both sides, and controls the matching plug-in plates 032 on both sides of the airbag mesh placement plate 031 to separate and approach synchronously, and is driven by the matching plug-in plate separation driving mechanism 6. When the matching plug-in plates 032 are separated, 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 limiting slide groove 621 changes, so that the single-rod bearing 76 is restricted by the limiting slide groove 621, thereby driving the matching plug-in plates on both sides to separate to both sides on the matching plug-in plate connecting frame guide rail 51 at the same time, so that the matching plug-in plates 032 connected above are separated from the airbag mesh placement plate 031 at the same time, which is convenient for the folding of the airbag mesh. When the matching plug-in plates 032 shrink and approach the airbag mesh placement plate 031, the synchronous adjustment plate 62 descends.

[0093] As the synchronous adjustment plate 62 rises, the airbag mesh positioning block 631 rises and extends from the positioning block movable opening 0311 to facilitate the placement of the airbag mesh. When the airbag mesh is folded and needs to be transferred, the airbag mesh positioning block 631 will withdraw from the positioning block movable opening 0311 as the synchronous adjustment plate 62 descends, ensuring that it will not protrude and is on the same plane as the airbag mesh placement plate 031.

[0094] In the present invention, the device integrates the folding, fixing and sewing functions into a single device, reducing the process conversion time, ensuring the accuracy of the folding position through the airbag mesh positioning block 631, and automatically folding the airbag mesh through the folding unit 05 and the folding auxiliary mechanism 03. The mirror panel 013 is designed to cooperate with the airbag mesh transfer plate 1, and the friction is increased in combination with the protrusion 13 to achieve smooth and rapid transfer of the mesh after folding, avoiding material displacement or damage. The overall device adopts a fully automated process to reduce manual intervention, reduce unit production costs, and is more efficient and high-quality than manual production in mass production.

[0095] The above description is only a preferred specific embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any technician familiar with the technical field, within the technical scope disclosed by the present invention, who makes equivalent replacements or changes based on the technical solution and inventive concept of the present invention, should be covered by the scope of protection of the present invention.
