The device includes a base, a lifting platform mechanism, a backsplash positioning and clamping mechanism, at least two transverse support wire positioning and clamping mechanisms, and at least two wire winding mechanisms. The method is applied to the aforementioned curtain weaving device.

Description

Technical Field

[0001] This invention relates to the field of mechanical design technology, and in particular to curtain weaving equipment and methods. Background Technology

[0002] As a core supporting component of car seats, the seat backsplash is a crucial structural foundation for ensuring seat comfort, safety, and lifespan. Its structural stability and dimensional accuracy directly determine the user experience and safety performance. Good structural stability prevents localized collapse or wobbling of the backsplash during driving; dimensional accuracy ensures precise fit between the backsplash and other seat components, reducing the risk of abnormal noises or structural failures caused by assembly gaps. The backsplash is typically formed into a frame structure by integrating horizontal bars, vertical bars, and horizontal bends. To enhance the overall rigidity and deformation resistance of the frame, it is reinforced and shaped by winding the ends of the horizontal support wires, ensuring that the backsplash does not deform, loosen, or have wires detach when subjected to long-term loads such as the weight of passengers and road bumps. Currently, the automotive manufacturing industry is rapidly developing towards large-scale mass production and high-precision quality control. The market has placed more stringent demands on the production efficiency, product consistency, and connection strength of automotive seat backrests. On the one hand, large-scale production requires increasing output per unit time to reduce manufacturing costs. On the other hand, consumers' high expectations for seat comfort and safety require backrest products to maintain a high degree of consistency in key indicators such as the number of wire windings, tightness, and connection positions. At the same time, it is necessary to further improve the connection strength between the wires and the frame to meet the reliability standards for long-term use in the automotive industry.

[0003] The back net positioning mechanism of existing semi-automatic equipment mostly adopts simple support or single-direction clamping, lacking multi-dimensional limiting of the back net's horizontal bars, vertical bars and transverse bends, which makes the back net prone to displacement and swaying during lifting or winding. The positioning of the transverse support steel wires mostly relies on manual alignment, without forming a comprehensive fixing structure of initial positioning, end clamping and intermediate pressing. The horizontality, spacing and end position deviation of the steel wires are large, which in turn causes the steel wires to be misaligned with the back net winding position, resulting in low product dimensional accuracy and structural asymmetry.

[0004] Meanwhile, the direct clamping method driven by a single cylinder, which lacks a stable transmission structure, easily leads to tilting of the clamping block and loose contact of the clamping surfaces. Furthermore, the clamping force is not precisely controlled, resulting in problems such as under-pressure causing loosening of the back net or steel wire, and over-pressure causing deformation of the back net or damage to the steel wire. In addition, the ends of the steel wires lack dedicated clamping structures, making them prone to slippage and misalignment during winding, affecting the winding connection strength. Long-term use may lead to steel wire detachment, posing a safety risk.

[0005] To address the aforementioned issues, there is an urgent need to develop a highly automated, precise, and stable curtain weaving equipment capable of simultaneous operation at two workstations. By integrating a precise positioning and clamping mechanism, a collaborative winding mechanism, and a closed-loop control system, this equipment can achieve efficient and high-precision winding and forming of automotive seat back nets and transverse support steel wires, thus meeting the high-quality production requirements of the automotive manufacturing industry for back net products.

[0077] One of the technical solutions adopted in this invention is a curtain weaving method, which is applied to the aforementioned curtain weaving equipment; the method includes:

[0078] S1. Before the equipment is started, the lifting platform mechanism is in the initial lowering position, the lifting telescopic cylinder is in the retracted state, and the installation platform is attached to the base surface.

[0079] S2. The horizontal clamping cylinder, vertical clamping cylinder, and clamping cylinder are all in the reset state, and the corresponding clamping blocks and clamping blocks remain open. The horizontal support steel wire clamping motor drives the clamping blocks to the loosened position.

[0080] S3. Place two symmetrical car seat back nets onto the back net positioning and clamping mechanism;

[0081] S4. Place each crossbar of the back net into the transverse support groove of the transverse support plate in the transverse support and pressing structure, with the overlapping part of the crossbar placed above the transverse lower pressing block.

[0082] S5. The transverse bend of the back net is embedded in the transverse bend support groove of the transverse bend support structure.

[0083] S6. The vertical rods of the back net are inserted into the vertical support grooves of the vertical support plate in the vertical support pressing structure, and the vertical rods are in contact with the surface of the vertical pressing block.

[0084] S7. The transverse support steel wire is embedded in the transverse support steel wire mounting groove of the transverse support steel wire mounting block. Both ends of the steel wire are led out to the outside of the mounting groove through the end guide block, and both ends are respectively placed on the winding cylindrical pins of the steel wire winding mechanism on both sides.

[0085] S8. Start the transverse pressing cylinder. Its telescopic end pushes the transverse upper pressing block. Through the hinge transmission of the transverse flipping connecting block, the transverse upper pressing block flips downward and presses the overlapping part of the two back net crossbars.

[0086] S9. Activate the four vertical clamping cylinders to drive the vertical clamping blocks to flip downwards, clamping the corresponding back net vertical rods respectively, thus completing the precise positioning and fixing of the back net;

[0087] S10. Start the clamping cylinder. Its telescopic end pushes the clamping plate, causing all clamping blocks to move along the clamping groove towards the transverse support wire, clamping both ends of the wire in the transverse support wire mounting groove.

[0088] S11. Then start the transverse support steel wire clamping motor to drive the transverse support steel wire clamping block to rotate, clamping the middle part of the steel wire to ensure that the steel wire does not shift during subsequent actions;

[0089] S12. Start the lifting telescopic cylinder of the lifting platform mechanism. Its telescopic end extends upward, driving the installation platform to rise. Simultaneously, it drives the back net positioning clamping mechanism and the transverse support steel wire positioning clamping mechanism fixed on the platform to rise as a whole. Until the two ends of the transverse support steel wire are aligned with the steel wire through holes at the center of the winding gear disk of the two side steel wire winding mechanisms, and the back net to be wound is matched with the position of the winding cylindrical pin, the lifting telescopic cylinder stops moving, and the platform maintains the current height.

[0090] S13. Start the transverse movement cylinder of the wire winding mechanism on both sides. Its extension end pushes the transverse movement push plate, which slides along the transverse guide slide rail through the transverse guide slider, thereby driving the winding mounting plate and subsequent winding components to move laterally. This allows one end of the transverse support wire to pass through the wire hole of the winding gear disk, and the wire to be in close contact with the surface of the winding cylindrical pin. After the transverse alignment is completed, the transverse movement cylinder is locked.

[0091] S14. Start the vertical rotation drive motor. Its rotating end drives the lead screw to rotate. The nut moves along the length of the lead screw. Through the transmission of the vertical mounting slider, the first connecting plate, and the second connecting plate, the horizontal mounting block and the winding assembly are driven to rise and fall smoothly along the vertical guide rail and the vertical guide chain, so that the winding assembly moves slowly along the length of the back net, providing vertical feed for the winding action.

[0092] S15. Start the winding drive motor. Its rotating end transmits power through the input shaft of the transmission gearbox. After transmission inside the gearbox, the output shaft drives the first driven gear to rotate. The first driven gear meshes with and drives the second driven gear, which in turn drives the winding gear disc to rotate. The winding gear disc drives one end of the transverse support steel wire to rotate around the corresponding part of the back net through the winding cylindrical pin on its surface, so that the two ends of the steel wire are tightly wound on the back net of the car seat.

[0093] S16. After winding is completed, the winding drive motor stops rotating, the vertical rotation drive motor reverses, and the winding assembly returns to the initial vertical position; the lateral movement cylinder resets, and the winding assembly retracts laterally; the lifting and telescopic cylinder retracts, and the installation platform and related mechanisms descend to the initial position; the lateral and vertical clamping cylinders retract, and the corresponding upper clamping blocks flip and loosen; the lateral support wire clamping motor reverses, and the clamping blocks loosen; the clamping cylinder retracts, and the clamping blocks retract, releasing the lateral support wires; the wound car seat back net is removed from the back net positioning and clamping mechanism, completing one work cycle.

[0094] This invention offers the following advantages: To meet the demands of large-scale, high-precision production of automotive seat backsplashes, this equipment employs a multi-mechanism collaborative design. Its core highlights lie in the symmetrically arranged backsplash positioning and clamping mechanism, the transverse support wire positioning and clamping mechanism, and the wire winding mechanism. These three components form a highly efficient linkage system, enabling the simultaneous winding of two automotive seat backsplashes and two transverse support wires. Compared to traditional single-station equipment, this dual-station synchronous operation mode significantly shortens the production cycle per unit product, substantially increases output per unit time, perfectly aligns with the core requirements of large-scale mass production in the automotive manufacturing industry, and effectively reduces time and labor costs in large-scale production.

[0095] In terms of ensuring positioning accuracy, the equipment features multiple precision limiting structures designed for both the back net and the steel wire. For the automotive seat back net, the equipment utilizes a combination of horizontal support grooves, vertical support grooves, and bending support grooves to achieve precise positioning of the back net in both horizontal and vertical directions, ensuring the accuracy of the back net's initial position during operation. Simultaneously, a cylinder-driven upper and lower clamping structure provides continuous and stable pressure during the winding process, effectively preventing displacement and swaying of the back net due to force, laying the foundation for precise implementation of subsequent winding processes. For the horizontal support steel wire, the equipment employs a triple fixing scheme: a shape-matched mounting groove, end clamping, and intermediate clamping. This triple structure works in tandem, providing layer-by-layer protection, ensuring both the horizontality and spacing accuracy of the steel wire, and precisely locking the end position. This fundamentally prevents winding offset problems caused by steel wire displacement during the winding process, ensuring the stability of the winding connection.

[0096] Furthermore, the equipment consistently adheres to the concept of symmetry in its key mechanism design. Both the wire winding mechanism and the back net positioning mechanism employ a strictly symmetrical layout, ensuring that the winding operations of the back nets on both sides are completely synchronized. This symmetrical design not only achieves efficient collaboration between the two workstations but also guarantees that the number of winding turns, tightness, and connection positions at both ends of the two transverse support wires are completely consistent. From a process perspective, this avoids quality risks such as asymmetrical back net structures and dimensional deviations that may be caused by unilateral deviations. Through the precise coordination and symmetrical design of multiple mechanisms, this equipment improves production efficiency while firmly maintaining the bottom line of product quality, providing a production solution for automotive seat back nets that combines efficient mass production with high-precision quality.

[0111] The technical solutions of the curtain weaving device and method provided by the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only a part of the embodiments of the present invention, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative effort are within the scope of protection of the present invention.

[0112] Example 1

[0113] like Figures 1-2As shown, a curtain weaving device is used to wrap the two ends of the transverse support steel wires around the back mesh of a car seat.

[0114] The device includes: a base 1, which supports all the components of the device.

[0115] In this embodiment, the base 1 ensures that each mechanism remains in a fixed position during operation, preventing the lateral support steel wire from affecting the winding accuracy of the car seat back mesh due to equipment shaking. It is the core support guarantee for the stable operation of the equipment.

[0116] The equipment also includes a lifting platform mechanism 2, which is mounted on the base 1. In this embodiment, the lifting platform mechanism 2 drives the two mechanisms to rise or fall synchronously through precise lifting movements, thereby adjusting the relative height of the car seat back net and the transverse support wire, so that the two ends of the transverse support wire can be accurately aligned with the winding position of the back net, providing precise positional coordination for the subsequent winding operation of the wire winding mechanism 5, and ensuring the smooth progress of the winding process. The equipment also includes a back net positioning and clamping mechanism 3, which is used to clamp two mutually symmetrical car seat back nets on the back net positioning and clamping mechanism 3; the back net positioning and clamping mechanism 3 is mounted on the lifting platform mechanism 2.

[0117] In this embodiment, the back net positioning and clamping mechanism 3 precisely positions and firmly clamps two symmetrical car seat back nets, preventing displacement or shaking during lifting or winding operations. This stable clamping and precise positioning ensures the relative positions of the two back nets meet process requirements, providing a unified benchmark for the synchronous winding of the transverse support wires at both ends, and ensuring the symmetrical and dimensionally accurate back net structure after winding.

[0118] The device also includes at least two transverse support wire positioning and clamping mechanisms 4, which are used to clamp two transverse support wires in the corresponding transverse support wire positioning and clamping mechanism 4; the two transverse support wire positioning and clamping mechanisms 4 are installed on the lifting platform mechanism 2 and arranged side by side.

[0119] Specifically, the two transverse support wire positioning and clamping mechanisms 4 clamp the two transverse support wires respectively. The precise positioning structure ensures that the wires' levelness and spacing meet process requirements. Simultaneously, the firm clamping prevents the wires from shifting or loosening during lifting and winding. Because the mechanism is located in the middle of the back net positioning and clamping mechanism 3, the ends of the two wires can be aligned with the back nets on both sides, providing precise wire positioning for the subsequent synchronous winding of the wire winding mechanism 5, ensuring accurate winding position of the wires and back nets.

[0120] The device includes at least two wire winding mechanisms 5, which are used to wind the two ends of the transverse support wires onto the corresponding car seat back mesh respectively; the two wire winding mechanisms 5 are mounted on the base 1 and arranged symmetrically to each other.

[0121] In this embodiment, after the lifting platform mechanism 2 completes its position adjustment, the two ends of the transverse support wire are respectively wound around the corresponding car seat back net. A preset winding process is used to achieve a firm connection between the wire and the back net. The two symmetrically arranged mechanisms can simultaneously complete the winding operation of the two wire ends, improving production efficiency while ensuring the consistency of the winding quality on both sides, ultimately forming a car seat back net structure that meets the requirements.

[0122] Two wire winding mechanisms 5 are respectively installed on both sides of the back net positioning and clamping mechanism 3, and two transverse support wire positioning and clamping mechanisms 4 are located in the middle of the back net positioning and clamping mechanism 3; the lifting platform mechanism 2 drives the back net positioning and clamping mechanism 3 and at least two transverse support wire positioning and clamping mechanisms 4 to rise or fall.

[0123] Example 2

[0124] like Figure 3 As shown in Embodiment 1, the lifting platform mechanism 2 further includes a mounting platform 201. In this embodiment, the mounting platform 201 provides a flat and stable mounting surface for the back net positioning and clamping mechanism 3 and at least two transverse support wire positioning and clamping mechanisms 4, ensuring that the back net positioning and clamping mechanism 3 and at least two transverse support wire positioning and clamping mechanisms 4 can be accurately fixed in a preset position, ensuring the consistency of the benchmark for subsequent positioning and clamping actions. Simultaneously, the mounting platform 201, through its connection with the lifting telescopic cylinder 202, converts the cylinder's telescopic power into its own lifting motion, thereby synchronously driving the back net positioning and clamping mechanism 3 and at least two transverse support wire positioning and clamping mechanisms 4 supported above to achieve height adjustment. It is a key intermediate component for realizing power transmission and mechanism linkage. The lifting platform mechanism 2 also includes a lifting telescopic cylinder 202, which is installed at the center of the base 1, with its telescopic end extending out of the surface of the base 1 and connected to the center of the mounting platform 201.

[0125] In this embodiment, the lifting and telescopic cylinder 202 drives the internal piston rod to extend and retract using compressed air, generating an upward or downward driving force. This directly drives the installation platform 201 and the back net positioning and clamping mechanism 3 and the transverse support wire positioning and clamping mechanism 4 above it to rise or fall synchronously. Furthermore, the lifting and telescopic cylinder 202 can achieve precise height control by adjusting the air pressure and stroke parameters, meeting the alignment requirements of different specifications of automotive seat back nets and transverse support wires, and providing stable height adjustment assurance for the subsequent precise operation of the wire winding mechanism 5. The lifting and telescopic cylinder 202 drives the installation platform 201 to rise or fall.

[0126] Specific working process: Before the equipment is started, the lifting and telescopic cylinder 202 is in the initial retracted state, which drives the installation platform 201 to the lowest position. At this time, the back net positioning clamping mechanism 3 and the transverse support steel wire positioning clamping mechanism 4 installed on the platform are also in the low position, which makes it convenient for the operator to install the two symmetrical car seat back nets into the back net positioning clamping mechanism 3 and complete the clamping and fixing. At the same time, the two transverse support steel wires are correspondingly installed into the transverse support steel wire positioning clamping mechanism 4 and completed the positioning and clamping.

[0127] Once the back net and steel wire are clamped and positioned, the equipment control system sends a command to the lifting telescopic cylinder 202 to rise. Compressed air enters the cylinder chamber, driving the piston rod to extend upwards. Because the cylinder's telescopic end is rigidly connected to the center of the installation platform 201, the extension force of the piston rod is evenly transmitted to the installation platform 201, causing the platform and the back net positioning clamping mechanism 3 and the transverse support steel wire positioning clamping mechanism 4 above it to rise synchronously and smoothly. During this process, the control system monitors the platform position in real time using preset parameters until the two ends of the transverse support steel wire are precisely aligned with the winding positions of the steel wire winding mechanisms 5 on both sides, and the position of the back net to be wound is completely matched with the end of the steel wire. At this point, the lifting telescopic cylinder 202 stops extending, and the installation platform 201 stabilizes at the target height. Next, the lifting platform mechanism 2 maintains its current height, providing stable positional support for the subsequent operation of the steel wire winding mechanism 5. At this time, the back net is fixed by the back net positioning clamping mechanism 3, and the steel wire is fixed by the transverse support steel wire positioning clamping mechanism 4. Their relative positions remain constant, ensuring that the steel wire winding mechanism 5 can smoothly wind the two ends of the steel wire onto the back net. After the wire winding operation is completed, the control system sends a descent command to the lifting and telescopic cylinder 202. The cylinder chamber exhausts air, and the piston rod retracts under its own weight and the platform load, causing the installation platform 201 and the two mechanisms above it to descend synchronously and smoothly until it returns to its initial low position. The operator can then remove the wound car seat back net, completing one work cycle. The lifting platform mechanism 2 awaits the next start command.

[0128] Example 3

[0129] like Figures 4-6 As shown, in a further embodiment of Example 1 or Example 2, the back net positioning and clamping mechanism 3 includes: a transverse support and pressing structure 301, which is used to support the crossbars of the corresponding car seat back nets respectively, and to press the overlapping parts of the crossbars of the two mutually symmetrical car seat back nets.

[0130] Furthermore, the lateral support clamping structure 301 includes at least two lateral support mounting columns 3011, which are vertically mounted on the mounting platform 201. The lateral support clamping structure 301 also includes at least two lateral support plates 3012, which are fixedly mounted on the corresponding lateral support mounting columns 3011; each lateral support plate 3012 is provided with a lateral support groove 3019; and the crossbar of each car seat back net is located in the corresponding lateral support groove 3019.

[0131] Specifically, the transverse support groove 3019 on the transverse support plate 3012 serves as the direct positioning carrier for the back net crossbars. By matching the shape and size of the transverse support groove 3019 with the crossbars, the crossbars of two symmetrical back nets can be embedded into their corresponding grooves, limiting the horizontal displacement of the crossbars and ensuring accurate lateral positioning of the crossbars, thus providing a reference for subsequent pressing of the overlapping parts.

[0132] The lateral support and clamping structure 301 further includes: a lateral clamping mounting post 3013, which is vertically mounted on the mounting platform 201; the lateral clamping mounting post 3013 is located between two lateral support mounting posts 3011. In this embodiment, the lateral clamping mounting post 3013 is designed to align with the overlapping portion of the two back net crossbars, providing stable mounting support for the clamping structure. The lateral support and clamping structure 301 further includes: a lateral lower clamping block 3014, which is mounted on the lateral clamping mounting post 3013; the overlapping portion of the two symmetrical car seat back net crossbars is located on the lateral lower clamping block 3014.

[0133] Specifically, the horizontal lower clamping block 3014 serves as the lower support surface for the overlapping part of the back net crossbar, bearing the weight of the overlapping part. At the same time, it cooperates with the subsequent horizontal upper clamping block 3016 to form an upper and lower clamping structure, preventing the crossbar from deforming due to the lack of bottom support during clamping.

[0134] The transverse support and clamping structure 301 further includes a transverse clamping cylinder 3015, which is mounted on the transverse clamping mounting column 3013. Specifically, the transverse clamping cylinder 3015 is driven by compressed air to move its telescopic end, providing clamping power to the transverse upper clamping block 3016, controlling the start and reset of the clamping action, and ensuring stable and controllable clamping force. The transverse support and clamping structure 301 also includes a transverse upper clamping block 3016, one end of which is hinged to the telescopic end of the transverse clamping cylinder 3015. Specifically, the transverse upper clamping block 3016 is driven downward by a cylinder, cooperating with the transverse lower clamping block 3014 to firmly clamp the overlapping part of the two back net crossbars, preventing the overlapping part from loosening or shifting during the winding operation. The transverse support and clamping structure 301 also includes a transverse flipping mounting block 3017, which is mounted on the transverse clamping cylinder 3015. The lateral flip-mounting block 3017 serves as the hinge base for the lateral flip-connecting block 3018, providing a fixed hinge point for the flip-connecting block and ensuring the stability of the connecting block's movement trajectory. The lateral support and clamping structure 301 also includes at least two parallel lateral flip-connecting blocks 3018, which connect the lateral flip-mounting block 3017 and the lateral upper clamping block 3016. The lateral clamping cylinder 3015 drives the lateral upper clamping block 3016 to clamp the overlapping portions of the two symmetrical crossbars of the car seat backrest net.

[0135] In this embodiment, one end of each of the two parallel transverse flipping connecting blocks 3018 is coaxially hinged to the transverse flipping mounting block 3017, and the other end is coaxially hinged to the transverse upper pressing block 3016. The two parallel transverse flipping connecting blocks 3018, through the structure of coaxial hinge at both ends, convert the linear motion of the extension end of the transverse pressing cylinder 3015 into the smooth flipping motion of the transverse upper pressing block 3016, avoid the pressing block from tilting, ensure that the pressing surface is evenly attached to the overlapping part of the crossbar, and improve the pressing stability.

[0136] The back net positioning and clamping mechanism 3 further includes at least two transverse bending portion support structures 302, which are used to support the transverse bending portions of the corresponding automotive seat back nets respectively. Further, the transverse bending portion support structure 302 includes at least two transverse bending portion support mounting columns 3021, which are vertically mounted on the mounting platform 201.

[0137] Specifically, the two transverse bend support mounting posts 3021 serve as the mounting carriers for the transverse bend support grooves 3022, providing vertical support for the support grooves. Their installation positions ensure precise alignment with the transverse bends of the back net, making them fundamental components of the support structure. The transverse bend support structure 302 also includes at least one transverse bend support groove 3022, which is formed on the corresponding transverse bend support mounting post 3021. Specifically, the groove shape of the transverse bend support groove 3022 matches the contour of the transverse bend of the back net, embedding the transverse bend into the groove, limiting the displacement of the bend in the horizontal and vertical directions, preventing deformation or displacement of the bend during winding operations, and helping to maintain the overall positioning accuracy of the back net. The crossbar of each automotive seat back net is located within the corresponding transverse bend support groove 3022.

[0138] The transverse bending support structure 302 further includes: the back net positioning and clamping mechanism 3 further includes: at least four vertical support and clamping structures 303, which are used to support the vertical rods of the corresponding car seat back nets respectively. Two transverse bending support structures 302 are located on either side of the transverse support and clamping structure 301; each pair of vertical support and clamping structures 303 are arranged back-to-back with each other. Further, the vertical support and clamping structure 303 includes: a vertical support and clamping mounting post 3031, which is vertically mounted on the mounting platform 201. The vertical support and clamping structure 303 also includes: a vertical support plate 3032, which is fixedly mounted on the corresponding vertical support and clamping mounting post 3031; each vertical support plate 3032 is provided with a vertical support groove 3033; the vertical rod of each car seat back net is located within the corresponding vertical support groove 3033.

[0139] In this embodiment, the vertical support groove 3033 on the vertical support plate 3032 serves as the direct positioning carrier for the vertical rods of the back net. By matching the dimensions of the groove with the vertical rod, the vertical rod is embedded in the groove, limiting its forward and backward displacement in the horizontal direction and ensuring the precise vertical position of the vertical rod. This, combined with the horizontal structure, forms the horizontal and vertical positioning net of the back net.

[0140] The vertical support and clamping structure 303 further includes: a downward vertical clamping block 3034, which is mounted on the vertical support and clamping mounting post 3031; the vertical rod of the car seat back net is located on the downward vertical clamping block 3034. In this embodiment, the downward vertical clamping block 3034 serves as the lower support surface of the back net vertical rod, bearing the weight of the vertical rod, and cooperates with the upward vertical clamping block 3036 to form an upper and lower clamping structure, preventing the vertical rod from deforming due to the lack of bottom support during clamping.

[0141] The vertical support and clamping structure 303 further includes a vertical clamping cylinder 3035, which is mounted on the vertical support and clamping mounting column 3031. Specifically, the vertical clamping cylinder 3035 serves as the power source for the vertical support and clamping structure. It is mounted on the vertical support and clamping mounting column 3031 and drives the telescopic end to move via compressed air, providing clamping power to the vertical clamping block 3036 and controlling the initiation and resetting of the vertical rod clamping action.

[0142] The vertical support and clamping structure 303 further includes a vertical upward clamping block 3036, one end of which is hinged to the telescopic end of the vertical clamping cylinder 3035. In this embodiment, the vertical upward clamping block 3036 is driven downward by the cylinder to cooperate with the vertical downward clamping block 3034 to firmly clamp the vertical pole of the back net, preventing the vertical pole from loosening or shifting during the winding operation, and further improving the overall stability of the back net.

[0143] The vertical support and clamping structure 303 further includes a vertical flip mounting block 3037, which is mounted on the vertical clamping cylinder 3035. In this embodiment, the vertical flip mounting block 3037 serves as the hinge base for the vertical flip connecting block 3038, providing a fixed hinge point to ensure the stability of the connecting block's movement trajectory.

[0144] The vertical support and clamping structure 303 further includes at least two parallel vertical flipping connecting blocks 3038, which connect the vertical flipping mounting block 3037 and the vertical clamping block 3036. One end of each of the two parallel vertical flipping connecting blocks 3038 is coaxially hinged to the vertical flipping mounting block 3037, and the other end is coaxially hinged to the vertical clamping block 3036. The vertical clamping cylinder 3035 drives the vertical clamping block 3036 to clamp the vertical rod of the car seat backrest net. Specifically, the two parallel vertical flipping connecting blocks 3038, through their coaxial hinged ends, convert the linear motion of the extension end of the vertical clamping cylinder 3035 into a smooth flipping motion of the vertical clamping block 3036, preventing the clamping block from tilting, ensuring that the clamping surface evenly adheres to the vertical rod, and improving the stability of the vertical clamping.

[0145] Its working process: The vertical pressing block 3036 and the vertical pressing cylinder 3035 are both in the initial reset state, which drives the vertical pressing block 3036 to lift upward. At this time, the horizontal support groove, the horizontal bending part support groove, and the vertical support groove are all in the open state, which facilitates the operator to place the car seat back net. The operator places two symmetrical car seat back nets on the mechanism, with the specific alignment as follows: The horizontal bars of the back net are respectively embedded in the horizontal support groove of the horizontal support plate 3012, and the overlapping part of the two horizontal bars rests on the horizontal lower pressing block 3014; the horizontal bending part of the back net is embedded in the horizontal bending part support groove 3022 of the horizontal bending part support mounting column 3021; ​​the vertical bars of the back net are respectively embedded in the vertical support groove 3033 of the vertical support plate 3032, and the vertical bars rest on the vertical lower pressing block 3034. After the initial positioning of the back net is completed, the equipment control system sends a clamping command to the horizontal clamping cylinder 3015. Compressed air enters the cylinder chamber, driving the telescopic end to extend. Through the transmission of the horizontal flipping connecting block 3018, the horizontal upper clamping block 3016 smoothly flips downward until it cooperates with the horizontal lower clamping block 3014, firmly clamping the overlapping part of the two crossbars, completing the horizontal clamping and restricting the vertical displacement of the crossbars. Synchronously or immediately after the horizontal clamping, the control system sends a clamping command to the vertical clamping cylinder 3035. Compressed air enters the cylinder chamber, driving the telescopic end to extend. Through the transmission of the vertical flipping connecting block 3038, the vertical upper clamping block 3036 smoothly flips downward until it cooperates with the vertical lower clamping block 3034, firmly clamping the vertical rods of the back net, completing the vertical clamping and restricting the vertical displacement of the vertical rods.

[0146] Example 4

[0147] like Figures 7-9 As shown in Embodiments 1, 2, or 3, the transverse support wire positioning and clamping mechanism 4 further includes at least two transverse support wire positioning and clamping mounting posts 401, which are fixedly mounted on the mounting platform 201. Specifically, the mounting positions of the two transverse support wire positioning and clamping mounting posts 401 are adapted to the transverse structure of the back net positioning and clamping mechanism 3, ensuring that the transverse support wire mounting block 402 can be aligned with the position to be wound on the back net. It serves as the supporting skeleton of the entire positioning and clamping mechanism, ensuring the accurate installation position of subsequent components.

[0148] The transverse support wire positioning and clamping mechanism 4 further includes a transverse support wire mounting block 402, whose two ends are fixedly mounted on the transverse support wire positioning and clamping mounting column 401. In this embodiment, the overall length of the transverse support wire mounting block 402 is adapted to the length of the transverse support wire, and the transverse support wire mounting groove 403 opened on the surface provides a dedicated placement space for the wire. At the same time, it integrates end guide blocks, clamping motors and other components, playing a dual role of component integration and wire bearing, and is the core connecting and bearing component of the mechanism.

[0149] The transverse support wire positioning and clamping mechanism 4 further includes a transverse support wire mounting groove 403, which is formed on the transverse support wire mounting block 402; the shape of the transverse support wire mounting groove 403 is consistent with the shape of the transverse support wire. The transverse support wire mounting groove 403 achieves initial positioning of the wire through shape matching. The groove depth and width design ensures that the wire will not shift arbitrarily in the horizontal direction after being placed, providing a reference for subsequent pressing and clamping, and is the core structure for wire positioning.

[0150] The transverse support wire positioning and clamping mechanism 4 further includes an end guide block 404, which is installed at both ends of the transverse support wire mounting block 402 to guide the two ends of the transverse support wire out of the transverse support wire mounting groove 403. Specifically, the end guide block 404 has a guide channel inside that communicates with the transverse support wire mounting groove 403. When the wire is placed into the mounting groove, the end guide block can accurately guide the two ends of the wire out of the mounting groove and limit the offset of the wire ends during the guiding process, ensuring that the two ends of the wire can be accurately aligned with the wire winding mechanisms 5 on both sides, providing accurate end positioning for subsequent winding operations.

[0151] The transverse support wire positioning and clamping mechanism 4 further includes at least two transverse support wire pressing motors 405, which are mounted on the transverse support wire mounting block 402.

[0152] In this embodiment, two transverse support wire clamping motors 405 drive the transverse support wire clamping blocks 406 to move through motor rotation. Compared with cylinder drive, motors can achieve more precise rotation angle control, ensuring that the clamping blocks can stably fit against the wire surface. At the same time, the clamping force can be adjusted according to the wire diameter to avoid excessive clamping force causing wire deformation or insufficient clamping force causing wire loosening. The transverse support wire positioning and clamping mechanism 4 also includes at least two transverse support wire clamping blocks 406, which are respectively installed on the rotating end of the transverse support wire clamping motors 405; the transverse support wire clamping motors 405 drive the transverse support wire clamping blocks to rotate and clamp the middle part of the transverse support wire. In this embodiment, the surfaces of the two transverse support wire clamping blocks 406 that contact the wire are provided with anti-slip textures or arc-shaped grooves that adapt to the shape of the wire. When the motor drives the clamping blocks to rotate, the clamping blocks can firmly press against the middle part of the transverse support wire, restricting the vertical displacement of the wire. Together with the transverse support wire mounting groove 403, the middle part of the wire can be fixed in all directions, both vertically and horizontally.

[0153] The transverse support wire positioning and clamping mechanism 4 further includes at least two transverse support wire end clamping structures 407, which are used to clamp the two ends of the transverse support wire into the transverse support wire mounting groove 403 respectively. Further, the transverse support wire end clamping structure 407 includes at least two clamping grooves 4071, which are formed on the groove edge of the transverse support wire mounting groove 403. Specifically, the two clamping grooves 4071 provide a motion guide channel for the clamping block 4072, ensuring that the clamping block can move accurately along the groove edge towards the wire, avoiding clamping failure due to block misalignment.

[0154] The transverse support wire end clamping structure 407 further includes at least two clamping blocks 4072, which are used to clamp one end of the transverse support wire in the transverse support wire mounting groove 403; one end of each clamping block 4072 is located in a corresponding clamping groove 4071. Specifically, the end faces of the two clamping blocks 4072 that contact the wire are provided with grooves adapted to the shape of the wire. When the clamping blocks 4072 move toward the wire, they can firmly press the end of the wire into the transverse support wire mounting groove 403, limiting the horizontal and vertical displacement of the end.

[0155] The transverse support wire end clamping structure 407 further includes a clamping plate 4073; one end of each clamping block 4072 is mounted on the clamping plate 4073. In this embodiment, the clamping plate 4073, through its overall movement, drives all clamping blocks to move simultaneously toward the wire, ensuring uniform clamping force at both ends of the wire and preventing wire deviation caused by excessively tight or loose clamping on one side.

[0156] The transverse support wire end clamping structure 407 further includes a clamping cylinder 4074, which is mounted on the mounting platform 201; the telescopic end of the clamping cylinder 4074 is connected to the clamping plate 4073. The clamping cylinder 4074 pushes the clamping plate 4073, causing each clamping block 4072 to move towards the transverse support wire, clamping one end of the transverse support wire in the transverse support wire mounting groove 403. In this embodiment, the clamping cylinder 4074 drives the clamping plate 4073 to move linearly through cylinder telescopic movement, thereby driving the clamping blocks 4072 to complete the clamping and releasing action. The action response is fast and the clamping force is stable, meeting the high-efficiency requirements of winding operations.

[0157] The working process is as follows: Before the equipment starts, the transverse support wire clamping motor 405 is in the reset state, and the clamping cylinder 4074 is in the retracted state. At this time, the transverse support wire mounting slot 403 is fully open, facilitating the placement of the transverse support wire by the operator. The operator places a transverse support wire into the transverse support wire mounting slot 403 of the transverse support wire mounting block 402. Since the shape of the transverse support wire mounting slot 403 perfectly matches the wire, the wire is initially limited in the horizontal direction after being placed, preventing it from shifting arbitrarily. At the same time, both ends of the wire extend along the transverse support wire mounting slot 403 to the end guide block 404, and are accurately guided out of the mounting slot through the guide channel of the guide block. The end position is aligned with the winding position of the wire winding mechanism 5 on both sides, completing the initial positioning. After the wire is initially positioned, the equipment control system sends a clamping command to the clamping cylinder 4074. The cylinder's telescopic end extends, pushing the connected clamping plate 4073 to move linearly in the direction of the wire. The clamping plate 4073 drives all clamping blocks 4072 to move synchronously along the clamping groove 4071 until the groove of the clamping block 4072 fits against the end of the steel wire, firmly pressing the end of the steel wire into the transverse support steel wire mounting groove 403, thus fixing both ends of the steel wire and restricting displacement in all directions at the end. After the end clamping is completed, the control system sends a clamping command to the transverse support steel wire pressing motor 405. The rotating end of the motor drives the transverse support steel wire pressing block 406 to rotate downward until the anti-slip surface or arc groove of the transverse support steel wire pressing block 406 fits tightly against the middle part of the steel wire, generating a stable clamping force, fixing the middle part of the steel wire in the transverse support steel wire mounting groove 403, and preventing the middle part of the steel wire from loosening or shifting vertically during the winding operation. At this time, the transverse support steel wire is initially positioned by the mounting groove, clamped at the end, and clamped in the middle, achieving all-round fixation, and both ends are accurately guided to the winding station by the end guide block 404. Subsequently, the lifting platform mechanism 2 drives the transverse support wire positioning and clamping mechanism 4 and the back net positioning and clamping mechanism 3 to rise synchronously, aligning the two ends of the wire with the position to be wound on the back net, and cooperating with the wire winding mechanism 5 to complete the winding operation. After the winding operation is completed, the lifting platform mechanism 2 descends to the initial position. The control system first controls the transverse support wire clamping motor 405 to reverse, driving the transverse support wire clamping block 406 to lift; then controls the clamping cylinder 4074 to retract, driving the clamping plate 4073 and clamping block 4072 to return to the initial position, releasing the wire. The operator can then remove the wound back net and wire assembly, and the mechanism awaits the next work cycle.

[0158] Example 5

[0159] like Figures 10-13As shown, in further detail in Embodiments 1, 2, 3, or 4, the wire winding mechanism 5 includes a wire winding mechanism mounting plate 501, which is fixedly mounted on the base 1. The wire winding mechanism 5 also includes a vertical rotation drive motor 502, which is mounted on the wire winding mechanism mounting plate 501. Specifically, the vertical rotation drive motor 502 drives the lead screw 503 to rotate, converting the motor's rotational motion into the linear motion of the nut 504, thereby driving subsequent components such as the horizontal mounting block 512 to achieve vertical lifting. The lifting speed can be controlled by the motor speed, and the lifting height can be controlled by the rotation angle, ensuring precise height adjustment.

[0160] The wire winding mechanism 5 further includes a lead screw 503, one end of which is mounted on the rotating end of the vertical rotation drive motor 502. The wire winding mechanism 5 also includes a nut 504, which is mounted on the lead screw 503. The lead screw 503 and the nut 504 form a lead screw-nut transmission pair. One end of the lead screw 503 is connected to the rotating end of the motor, and the nut 504 is fitted onto the lead screw and fixed to the vertical mounting slider 505. In this embodiment, when the lead screw rotates, the nut 504 moves along the length of the lead screw, converting the rotational power of the motor into vertical linear power, providing stable transmission for the lifting and lowering of the horizontal mounting block 512. This transmission is highly accurate, without slippage, ensuring accurate vertical position adjustment.

[0161] The wire winding mechanism 5 further includes a vertical mounting slider 505, which is mounted on the nut 504. Specifically, the vertical mounting slider 505 synchronously transmits the vertical movement of the nut 504 to the horizontal mounting block 512, and provides a vertical mounting reference for the horizontal mounting block 512, ensuring that the horizontal mounting block remains horizontal during the lifting process and avoiding tilting that could lead to misalignment during subsequent winding.

[0162] The wire winding mechanism 5 further includes a vertical guide rail 506, which is mounted on the wire winding mechanism mounting plate 501 and parallel to the lead screw 503. The wire winding mechanism 5 also includes a vertical guide slider 507, which is mounted on the vertical guide rail 506. The vertical guide rail 506 and the vertical guide slider 507 form a vertical guide pair. The vertical guide rail 506 is mounted parallel to the lead screw 503 on the wire winding mechanism mounting plate 501, and the vertical guide slider 507 is fitted onto the rail and fixed to the horizontal mounting block 512. Specifically, the vertical guide slider 507 restricts the movement direction of the horizontal mounting block 512, allowing it to move only vertically, preventing the horizontal mounting block from shifting due to the radial force of the lead screw drive, and ensuring the stability and straightness of the vertical lifting.

[0163] The wire winding mechanism 5 further includes a chain mounting plate 508, which is vertically mounted on the wire winding mechanism mounting plate 501. The wire winding mechanism 5 also includes a vertical guide chain 509, which is mounted on the chain mounting plate 508. In this embodiment, the chain mounting plate 508 and the chain mounting plate 509 assist in balancing the weight of the horizontal mounting block 512, reducing the load on the lead screw and nut pair, and further restricting the rotation of the vertical mounting slider, improving the stability of vertical adjustment, and preventing positional deviations caused by component sag due to gravity.

[0164] The wire winding mechanism 5 further includes: a first connecting plate 510, one end of which is mounted on the vertical mounting slider 505. The wire winding mechanism 5 also includes: a second connecting plate 511, one end of which is connected to the vertical guide chain 509, and the other end of which is connected to the first connecting plate 510. In this embodiment, the first connecting plate 510 and the second connecting plate 511 serve as connecting components between the vertical guide chain 509 and the vertical mounting slider 505, transmitting the vertical guiding force of the chain to the slider, ensuring that the slider always moves synchronously with the chain during lifting and lowering, further enhancing the linearity of the vertical movement, and preventing the slider from swaying or twisting.

[0165] The wire winding mechanism 5 further includes a horizontal mounting block 512, one end of which is mounted on the vertical mounting slider 505, and the other end is mounted on the vertical guide slider 507. The nut 504 drives the horizontal mounting block 512 on the vertical mounting slider 505 to move along the length of the lead screw 503. The horizontal mounting block 512 receives the power from the vertical adjustment component, drives the horizontal component to rise and fall as a whole, and provides a stable installation reference for the horizontal moving cylinder, ensuring that the horizontal alignment direction is consistent with the axial direction of the wire end.

[0166] The wire winding mechanism 5 further includes a lateral movement cylinder 513, which is mounted on the lateral mounting block 512. Specifically, the lateral movement cylinder 513 pushes the lateral movement push plate 514 through its telescopic end, thereby realizing the lateral movement of winding components such as the winding mounting plate 517. The cylinder has a fast response and stable clamping force, and can accurately control the lateral movement distance, ensuring that the wire through-hole of the winding gear disc 522 can be accurately fitted into the end of the lateral support wire.

[0167] The wire winding mechanism 5 further includes a transverse moving push plate 514, which is mounted on the telescopic end of the transverse moving cylinder 513. Specifically, the transverse moving push plate 514 transmits the transverse telescopic movement of the cylinder to the guide slider, thereby driving the winding mounting plate 517 to move, playing a role in power transmission and force buffering, and avoiding impact deformation caused by the cylinder directly pushing the winding component. The wire winding mechanism 5 also includes a transverse guide slide rail 515, which is mounted on the transverse moving cylinder 513. The wire winding mechanism 5 further includes a transverse guide slider 516, which is mounted on the transverse guide slide rail 515, and one end is connected to the transverse moving push plate 514.

[0168] In this embodiment, the transverse guide rail 515 and the transverse guide slider 516 form a transverse guide pair. The transverse guide rail 515 is mounted on the transverse moving cylinder 513, and the transverse guide slider 516 is sleeved on the rail and fixed to the winding mounting plate 517. Its function is to restrict the movement direction of the winding mounting plate 517, allowing it to move only laterally, avoiding misalignment between the winding gear disk 522 and the end of the wire due to cylinder thrust deviation, and ensuring the accuracy of transverse alignment. The wire winding mechanism 5 also includes: the winding mounting plate 517, which is mounted on the transverse guide slider 516. The wire winding mechanism 5 also includes: the winding mounting housing 518, one end of which is mounted on the end face of the winding mounting plate 517; the other end of the winding mounting housing 518 has a notch. Specifically, the winding mounting housing 518 serves to protect the components and position the gears. The notch at the other end of the housing corresponds to the notch in the transmission gearbox 521, providing installation space for the winding gear disk 522 and ensuring that the gear disk can accurately mesh with the second driven gear 520.

[0169] The wire winding mechanism 5 further includes a first driven gear 519, which is located inside the winding mounting housing 518. The wire winding mechanism 5 also includes a second driven gear 520, which is located inside the winding mounting housing 518 and meshes with the first driven gear 519.

[0170] Specifically, the first driven gear 519 and the second driven gear 520 form a gear transmission pair. The center of the first driven gear is mounted on the output shaft of the transmission gearbox 521. The second driven gear meshes with the first driven gear and also meshes with the winding gear disk 522. Its function is to change the transmission direction and transmit the power of the winding drive motor 524, ensuring that the winding gear disk obtains a stable rotational torque.

[0171] The wire winding mechanism 5 further includes a transmission gearbox 521, which is mounted on the winding mounting plate 517 and the winding mounting housing 518. The housing of the transmission gearbox 521 has a notch of the same size and corresponding position to the notch. The first driven gear 519 is mounted at its center on the output shaft of the transmission gearbox 521. Specifically, the transmission gearbox 521 adjusts the speed and torque of the motor, ensuring that the winding gear disc 522 obtains the rotational speed and torque required by the winding process, preventing excessive speed from causing loose winding or insufficient torque from causing winding failure. The notch on the housing mates with the notch in the winding mounting housing 518, ensuring sufficient space for the installation and meshing of the winding gear disc.

[0172] The wire winding mechanism 5 further includes: a winding gear disk 522, which is installed in the slot and notch; the winding gear disk 522 meshes with the second driven gear 520; and a wire through hole is provided at the center of the winding gear disk 522. In this embodiment, the winding gear disk 522 meshes with the second driven gear 520 and is the core execution component of the winding action. The wire through hole at the center of the gear disk is used to fit the end of the transverse support wire, ensuring that the end of the wire does not shift during winding; the winding cylindrical pin 523 on the surface of the gear disk is used to hook the end of the wire. When the gear disk rotates, the cylindrical pin drives the wire to wind around the crossbar of the car seat back mesh, forming a strong connection structure.

[0173] The wire winding mechanism 5 further includes: a winding cylindrical pin 523, which is mounted on the surface of the winding gear disc 522; one end of the transverse support wire is located on the winding cylindrical pin 523; the winding cylindrical pin 523 is a key component that hooks the wire and drives the winding. When the end of the wire passes through the wire through hole, the cylindrical pin contacts the wire and generates friction. When the gear disc rotates, the cylindrical pin drives the wire to wind along the back mesh crossbar, ensuring that the number of winding turns and the tightness meet the process requirements and preventing the wire from slipping during the winding process.

[0174] The wire winding mechanism 5 further includes a winding drive motor 524, which is mounted on a transmission gearbox 521; the rotating end of the winding drive motor 524 is connected to the input shaft of the transmission gearbox 521. The winding drive motor 524 drives the input shaft of the transmission gearbox 521 to rotate through its rotating end. The motor can adjust its rotation direction and number of rotations through a control system, providing continuous and stable rotational power to the winding gear disc 522, and is the core power source for the winding operation.

[0175] Example 6

[0176] A curtain weaving method, applied to the curtain weaving equipment described in Embodiment 5 above; the method includes:

[0177] S1. Before the equipment is started, the lifting platform mechanism 2 is in the initial lowering position, the lifting telescopic cylinder 202 is in the retracted state, and the mounting platform 201 is attached to the surface of the base 1.

[0178] S2, the horizontal pressing cylinder 3015, the vertical pressing cylinder 3035, and the clamping cylinder 4074 are all in the reset state, the corresponding pressing blocks and clamping blocks remain open, and the horizontal support steel wire pressing motor 405 drives the pressing blocks to the loosened position.

[0179] Furthermore, displacement sensors can be installed on the cylinder bodies of the horizontal clamping cylinder 3015 and the vertical clamping cylinder 3035. These displacement sensors can be used to detect the extension and retraction positions of the piston rods of the horizontal clamping cylinder 3015 and the vertical clamping cylinder 3035. A proximity sensor is installed next to the clamping plate 4073 of the clamping cylinder 4074. The proximity sensor provides a reset signal to confirm that the clamping block and clamping block are fully open, preventing initial jamming from affecting subsequent actions.

[0180] In this embodiment, the initial positions of the lifting platform mechanism, various cylinders, and motors are clearly defined in steps S1-S2 before equipment startup, ensuring that all components of the equipment are in a zero-interference initial state. Simultaneously, displacement sensors are innovatively installed on the bodies of the horizontal and vertical pressing cylinders, and proximity sensors are installed next to the clamping cylinders, enabling precise detection of the opening state of the pressing and clamping blocks. This design avoids subsequent action delays caused by initial state obstruction, laying the foundation for a smooth start-up of the entire curtain weaving process, reducing equipment debugging time, and improving overall processing efficiency.

[0181] S3. Place two symmetrical car seat back nets on the back net positioning and clamping mechanism 3.

[0182] S4. Place each crossbar of the back net into the transverse support groove of the transverse support plate 3012 in the transverse support and pressing structure 301, with the overlapping part of the crossbar positioned above the transverse lower pressing block 3014.

[0183] S5. The transverse bend of the back net is embedded in the transverse bend support groove 3022 of the transverse bend support structure 302.

[0184] S6. The vertical rod of the back net is inserted into the vertical support groove 3033 of the vertical support plate 3032 in the vertical support pressing structure 303, and the vertical rod is attached to the surface of the vertical pressing block 3034.

[0185] Furthermore, visual sensors are installed above the horizontal support plate 3012, the horizontal bending section support mounting column 3021, and the vertical support plate 3032, respectively. The sensors capture real-time images of the positions of the horizontal bars, bending sections, and vertical bars of the back net, and use image recognition to determine whether they are fully embedded in the corresponding slots. For example, they determine whether the horizontal bars are flush with the bottom of the horizontal support slot and whether the vertical bars are aligned with the sidewalls of the vertical support slot. If the back net is not accurately positioned, a warning is issued, and the operator adjusts and re-inspects to ensure that the initial positioning of the back net is accurate.

[0186] S7. The transverse support wire is embedded in the transverse support wire mounting groove 403 of the transverse support wire mounting block 402. The two ends of the wire are led out to the outside of the mounting groove through the end guide block 404, and the two ends are respectively placed on the winding cylindrical pins 523 of the wire winding mechanism 5 on both sides.

[0187] Furthermore, a vision sensor and a proximity sensor are installed at the outlet of the end guide block 404 and next to the winding cylindrical pin 523, respectively. The vision sensor detects whether the end of the steel wire is completely exited to avoid insufficient exit length affecting subsequent perforation. The proximity sensor detects whether the steel wire is in contact with the surface of the winding cylindrical pin 523 to ensure that the steel wire is in contact with the cylindrical pin and to prevent slippage during winding. After passing the detection, proceed to the next step.

[0188] In this embodiment, during the positioning process of the back net and the transverse support wires, specifically in steps S3-S7: For the back net, the placement positions of the horizontal bars, transverse bends, and vertical bars are clearly defined. Visual sensors are installed above the corresponding support structures, and image recognition technology is used to determine whether each component is fully embedded in its corresponding groove. For example, it checks whether the horizontal bars are flush with the bottom of the transverse support groove and whether the vertical bars are aligned with the sidewalls of the vertical support groove, ensuring that the initial positioning of the back net is without deviation. For the transverse support wires, visual sensors and proximity sensors are installed at the end of the guide block and next to the winding cylindrical pin, respectively, to detect the wire end's exit and its contact with the cylindrical pin, preventing insufficient exit length or poor contact from affecting subsequent processes. Precise positioning provides an accurate benchmark for subsequent key steps such as pressing and winding, which is a prerequisite for ensuring the quality of the woven curtain product.

[0189] S8. Start the transverse pressing cylinder 3015. Its telescopic end pushes the transverse upper pressing block 3016. Through the hinge transmission of the transverse flipping connecting block 3018, the transverse upper pressing block 3016 flips downward to press the overlapping part of the two back net crossbars.

[0190] S9. Activate the four vertical clamping cylinders 3035, which drive the vertical clamping blocks 3036 to flip downwards, clamping the corresponding back net vertical rods respectively, thus completing the precise positioning and fixing of the back net.

[0191] Furthermore, pressure sensors are embedded in the clamping surfaces of the horizontal clamping block 3016 and the vertical clamping block 3036, respectively. When the clamping block contacts the back net, the sensor provides real-time feedback on the clamping force value. If the pressure is lower than the preset clamping force, i.e., underpressure occurs, which may cause the back net to loosen. In this case, the system controls the cylinder to continue extending. If the pressure is higher than the preset clamping force, i.e., overpressure occurs, which may cause the back net to deform. In this case, the system controls the cylinder to stop moving and make a fine adjustment to retract, ensuring that the clamping force is within the process requirement range, and that the back net is fixed firmly without damage.

[0192] S10. Start the clamping cylinder 4074. Its telescopic end pushes the clamping plate 4073, which drives all the clamping blocks 4072 to move along the clamping groove 4071 toward the transverse support wire, clamping both ends of the wire in the transverse support wire mounting groove 403.

[0193] S11. Then start the transverse support wire clamping motor 405, which drives the transverse support wire clamping block 406 to rotate, clamping the middle part of the wire to ensure that the wire does not shift in subsequent actions.

[0194] Furthermore, pressure sensors are installed on the clamping surface of the clamping block 4072 and the pressing surface of the transverse support wire pressing block 406 respectively; in S10, the sensor detects the clamping force at the end of the wire to avoid displacement during winding due to excessively loose clamping at the end; in S11, the sensor detects the pressing force in the middle of the wire to prevent excessive pressing force in the middle from causing deformation of the wire. The dual pressure detection ensures accurate fixing of the entire wire.

[0195] In this embodiment, from S8 to S11, the method employs a dual-protection mode of mechanical action and pressure detection in the clamping and fixing process of the back net and the transverse support wires. On one hand, the orderly action of the transverse clamping cylinder, the vertical clamping cylinder, the clamping cylinder, and the transverse support wire clamping motor achieves physical clamping and fixing of the back net and the wires, ensuring that the components do not shift during subsequent processing. On the other hand, pressure sensors are embedded in the key contact surfaces of the transverse clamping block, the vertical clamping block, the clamping block, and the transverse support wire clamping block to provide real-time feedback on the clamping force. When underpressure occurs, the system controls the cylinder to continue extending to ensure a firm fixation; when overpressure occurs, the system controls the cylinder to stop moving and finely adjust its retraction to prevent deformation of the back net or damage to the wires. This design ensures the reliability of component fixing while maximizing the protection of the processed parts, effectively reducing the scrap rate.

[0196] S12. Start the lifting telescopic cylinder 202 of the lifting platform mechanism 2. Its telescopic end extends upward, driving the installation platform 201 to rise. Simultaneously, it drives the back net positioning clamping mechanism 3 and the transverse support steel wire positioning clamping mechanism 4, which are fixed on the platform, to rise as a whole. Until the two ends of the transverse support steel wire are aligned with the steel wire through holes at the center of the winding gear disk 522 of the two side steel wire winding mechanisms 5, and the back net to be wound is matched with the position of the winding cylindrical pin 523, the lifting telescopic cylinder 202 stops moving, and the platform maintains the current height.

[0197] Furthermore, a displacement sensor is installed on the cylinder body of the lifting and telescopic cylinder 202, and a vision sensor is installed next to the winding gear disk 522. The displacement sensor provides real-time feedback on the rising height of the installation platform 201. When the height approaches the preset value, the system reduces the cylinder's rising speed. At the same time, the vision sensor captures the alignment status of the wire end and the wire through-hole. The system uses image recognition to determine whether the two are coaxial. If there is a deviation, the system fine-tunes the lifting cylinder's action until the alignment is accurate and then stops, thus preventing the wire from failing to pass through the hole due to a deviation in the lifting height.

[0198] S13. Start the transverse movement cylinder 513 of the wire winding mechanism 5 on both sides. Its telescopic end pushes the transverse movement push plate 514, which slides along the transverse guide slide rail 515 through the transverse guide slider 516, thereby driving the winding mounting plate 517 and subsequent winding components to move laterally. This allows one end of the transverse support wire to pass through the wire through hole of the winding gear disk 522, and the wire to be in close contact with the surface of the winding cylindrical pin 523. After the transverse alignment is completed, the transverse movement cylinder 513 is locked.

[0199] Furthermore, a displacement sensor is installed on the cylinder body of the lateral movement cylinder 513, and a proximity sensor is installed next to the wire through hole of the winding gear disk 522. The displacement sensor controls the lateral movement distance to avoid excessive movement that could cause the wire to bend. The proximity sensor detects whether the wire has passed through the through hole. After confirming that the alignment is complete, the system controls the cylinder to lock to prevent the component from shifting during subsequent winding.

[0200] In this embodiment, during the lifting platform mechanism operation in S12 and the lateral alignment process of the wire winding mechanism in S13, the method achieves high-precision coordinated operation through multi-sensor collaboration and speed control. In the lifting phase, a displacement sensor installed on the lifting telescopic cylinder controls the lifting height, and a vision sensor installed next to the winding gear disc judges the alignment status of the wire end with the through hole. When the height approaches a preset value, the cylinder's lifting speed is reduced; if there is an alignment deviation, the cylinder's action is fine-tuned to ensure accurate alignment. In the lateral alignment phase, a displacement sensor on the lateral movement cylinder controls the movement distance, and a proximity sensor next to the through hole on the winding gear disc confirms the wire's passage, preventing excessive movement that could cause wire bending or alignment failure. Precise lifting and alignment provide stable and reliable operating conditions for the subsequent winding process, ensuring smooth winding.

[0201] S14. Start the vertical rotation drive motor 502. Its rotating end drives the lead screw 503 to rotate. The nut 504 moves along the length of the lead screw 503. Through the transmission of the vertical mounting slider 505, the first connecting plate 510, and the second connecting plate 511, the horizontal mounting block 512 and the winding assembly are driven to rise and fall smoothly along the vertical guide rail 506 and the vertical guide chain 509, so that the winding assembly moves slowly along the length of the back net, providing vertical feed for the winding action.

[0202] Furthermore, a linear displacement sensor is installed next to the lead screw 503, and a speed sensor is installed on the winding mounting plate 517. The displacement sensor provides real-time feedback on the vertical feed position of the winding assembly to ensure that the feed amount meets the process requirements and avoids loose winding due to excessive feed or excessive winding due to excessive slow feed. The speed sensor monitors the feed speed. If the speed fluctuation exceeds the preset speed, the system adjusts the speed of the vertical rotation drive motor 502 to ensure smooth feed and uniform winding quality.

[0203] S15. Start the winding drive motor 524. Its rotating end transmits power through the input shaft of the transmission gearbox 521. After transmission inside the gearbox, the output shaft drives the first driven gear 519 to rotate. The first driven gear 519 meshes with and drives the second driven gear 520, which in turn drives the winding gear disk 522 to rotate. The winding gear disk 522 drives one end of the transverse support steel wire to rotate around the corresponding part of the back net through the winding cylindrical pin 523 on its surface, so that the two ends of the steel wire are tightly wound on the back net of the car seat.

[0204] Furthermore, a torque sensor is installed on the output shaft of the winding drive motor 524, and a counting sensor is installed next to the winding gear disk 522. The counting sensor records the number of rotations of the winding gear disk 522, and triggers a motor stop signal after the number of rotations is reached. The torque sensor detects the torque value during the winding process. If the torque is too large or too small, the system adjusts the motor output power in real time to ensure stable winding torque and meet the connection strength requirements.

[0205] In this embodiment, during the wire winding process (S14-S15), the method ensures winding quality through multi-parameter monitoring and real-time adjustment. For vertical feeding, a linear displacement sensor is installed next to the lead screw to provide feedback on the feed position, ensuring the feed amount meets process requirements. Simultaneously, a speed sensor is installed on the winding mounting plate to monitor the feed speed. If the speed fluctuation exceeds a preset range, the speed of the vertical rotation drive motor is adjusted to ensure smooth feeding and prevent loose or overly dense winding. For winding power control, a torque sensor is installed on the output shaft of the winding drive motor to detect the winding torque and adjust the motor output power in real time to ensure torque stability. A counting sensor next to the winding gear disc records the number of rotations, triggering a motor stop signal after reaching a preset number of rotations. These designs ensure that the feed amount, feed speed, winding torque, and number of winding rotations are all within a precisely controllable range during the winding process, guaranteeing uniform and consistent connection strength between the transverse support wires and the back mesh, thus improving the overall product performance.

[0206] S16. After winding is completed, the winding drive motor 524 stops rotating, the vertical rotation drive motor 502 reverses, and drives the winding assembly back to the initial vertical position; the horizontal movement cylinder 513 resets, and drives the winding assembly to retract laterally; the lifting and telescopic cylinder 202 retracts, and drives the installation platform 201 and related mechanisms to descend to the initial position; the horizontal pressing cylinder 3015 and the vertical pressing cylinder 3035 retract, and drive the corresponding upper pressing block to flip and loosen; the horizontal support wire pressing motor 405 reverses, and drives the pressing block to loosen; the clamping cylinder 4074 retracts, and drives the clamping block to retract, releasing the horizontal support wire; the wound car seat back net is removed from the back net positioning clamping mechanism 3, completing one work cycle.

[0207] Furthermore, proximity sensors are installed next to the initial positions of the mounting platform 201, the winding assembly, the clamping block, and the holding block. When each component is reset, the sensor detects whether it has returned to its initial position. Only after all sensors have returned a signal indicating that the reset is complete will the system allow the next cycle to begin, thus avoiding operation failures caused by components not being reset.

[0208] In this embodiment, at the final stage of the entire curtain weaving process, the method not only specifies the reset actions of each component, but also installs proximity sensors near the initial positions of key components such as the mounting platform, winding assembly, pressing block, and clamping block. The system only allows the next cycle operation after all sensors have returned a signal indicating that the component reset is complete. This closed-loop process design effectively avoids subsequent operation failures caused by individual components failing to reset, ensuring the safety and stability of the equipment's cyclical operation. It also provides a reliable guarantee for the automated continuous production of the equipment, further improving production efficiency.

[0209] The foregoing has provided a detailed description of one embodiment of the present invention, but this description is merely a preferred embodiment and should not be construed as limiting the scope of the invention. All equivalent variations and modifications made within the scope of the claims of this invention should still fall within the patent coverage of this invention.

The vertical rod of the back net is inserted into the vertical support groove (3033) of the vertical support plate (3032) in the vertical support pressing structure (303), and the vertical rod is attached to the surface of the vertical pressing block (3034). S7. The transverse support wire is embedded in the transverse support wire mounting groove (403) of the transverse support wire mounting block (402). The two ends of the wire are led out to the outside of the mounting groove through the end guide block (404), and the two ends are respectively placed on the winding cylindrical pin (523) of the wire winding mechanism (5) on both sides. S8. Start the transverse pressing cylinder (3015), its telescopic end pushes the transverse upper pressing block (3016), and through the hinge transmission of the transverse flipping connecting block (3018), the transverse upper pressing block (3016) flips down to press the overlapping part of the two back net crossbars. S9. Activate the four vertical clamping cylinders (3035), which drive the vertical clamping blocks (3036) to flip downwards, clamping the corresponding back net vertical rods respectively, thus completing the precise positioning and fixing of the back net; S10. Start the clamping cylinder (4074). Its telescopic end pushes the clamping plate (4073), causing all clamping blocks (4072) to move along the clamping groove (4071) towards the transverse support wire, clamping both ends of the wire in the transverse support wire mounting groove (403). S11. Then start the transverse support wire clamping motor (405) to drive the transverse support wire clamping block (406) to rotate, clamp the middle part of the wire, and ensure that the wire does not shift in subsequent actions. S12, start the lifting telescopic cylinder (202) of the lifting platform mechanism (2), its telescopic end extends upward, driving the installation platform (201) to rise, and simultaneously driving the back net positioning clamping mechanism (3) and the transverse support steel wire positioning clamping mechanism (4) fixed on the platform to rise as a whole; until the two ends of the transverse support steel wire are aligned with the steel wire through holes at the center of the winding gear disk (522) of the two side steel wire winding mechanism (5), and the back net to be wound is matched with the position of the winding cylindrical pin (523), the lifting telescopic cylinder (202) stops moving, and the platform maintains the current height; S13. Start the transverse movement cylinder (513) of the wire winding mechanism (5) on both sides. Its telescopic end pushes the transverse movement push plate (514). The transverse guide slider (516) slides along the transverse guide rail (515), driving the winding mounting plate (517) and subsequent winding components to move laterally, so that one end of the transverse support wire passes through the wire hole of the winding gear disk (522), and the wire is close to the surface of the winding cylindrical pin (523). After the transverse alignment is completed, the transverse movement cylinder (513) is locked. S14. Start the vertical rotation drive motor (502), whose rotating end drives the lead screw (503) to rotate, and the nut (504) moves along the length direction of the lead screw (503). Through the transmission of the vertical mounting slider (505), the first connecting plate (510), and the second connecting plate (511), the horizontal mounting block (512) and the winding assembly are driven to rise and fall smoothly along the vertical guide rail (506) and the vertical guide chain (509), so that the winding assembly moves slowly along the length direction of the back net, providing vertical feed for the winding action; S15. Start the winding drive motor (524). Its rotating end transmits power through the input shaft of the transmission gearbox (521). After transmission inside the gearbox, the output shaft drives the first driven gear (519) to rotate. The first driven gear (519) meshes with and drives the second driven gear (520), which in turn drives the winding gear disk (522) to rotate. The winding gear disk (522) drives one end of the transverse support steel wire to rotate around the corresponding part of the back net through the winding cylindrical pin (523) on the surface, so that the two ends of the steel wire are tightly wound on the back net of the car seat. S16. After winding is completed, the winding drive motor (524) stops rotating, the vertical rotation drive motor (502) reverses, and drives the winding assembly back to the initial vertical position; the horizontal movement cylinder (513) resets, and drives the winding assembly to retract laterally; the lifting telescopic cylinder (202) retracts, and drives the installation platform (201) and related mechanisms to descend to the initial position; the horizontal pressing cylinder (3015) and the vertical pressing cylinder (3035) retract, and drive the corresponding upper pressing block to flip and loosen; the horizontal support wire pressing motor (405) reverses, and drives the pressing block to loosen; the clamping cylinder (4074) retracts, and drives the clamping block to retract, releasing the horizontal support wire; the wound car seat back net is removed from the back net positioning clamping mechanism (3), completing one work cycle.
