[0002] In the field of automotive interior manufacturing, the production process of seat covers has a crucial impact on the quality of the final product. As a component that directly contacts the driver and passengers, seat covers not only need to meet the requirements of aesthetics and comfort, but also need to have good durability and anti-wrinkle performance. With the continuous development of the automotive industry, consumers' expectations for the quality of seat covers are increasing, which prompts manufacturers to seek more advanced and efficient processes and equipment in the production process. However, the problem of fabric wrinkles has always been a difficult problem in the sewing process of seat covers. Traditional sewing methods often fail to effectively control the flatness of the fabric during sewing, resulting in wrinkles in the final sewn seat cover, which not only affects the appearance, but also may reduce the comfort and service life of the seat.

[0003] The existing seat cover sewing device generally only performs simple sewing operation after fixing the seat cover fabric. However, the existing seat cover sewing device does not consider the wrinkles or deformation of the fabric itself.

They are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. They should not be construed as limiting the specific protection scope of this application.

[0031] It should be noted that the terms "first," "second," etc., in the specification and claims of this application are used to distinguish similar objects and are not necessarily used to describe a specific order or sequence.

[0032] One preferred embodiment of this application, such as Figures 1 to 6 As shown, a seat cover anti-wrinkle sewing device includes: a workbench 1, and further includes: a sewing machine 7, a support plate 1 8, a stretching plate 9, a drive assembly, a limiting assembly 1, a support plate 2 10, a mounting plate 11, a clamping assembly, a smoothing assembly, and a pressing plate 12; the sewing machine 7 is fixedly installed at one end of the top of the workbench 1; the support plate 1 8 is vertically fixedly installed at the middle position of the other end of the top of the workbench 1; a sliding groove 1 is provided at the other end and the middle position of the other side of the top of the workbench 1, and the bottom ends of the stretching plate 9 are slidably installed with the bottom inner walls of the two sliding grooves 1 respectively through the sliding assembly, and the stretching plate 9 is arranged parallel to the support plate 1 8; the drive assembly is installed between the support plate 1 8 and the stretching plate 9 to drive the stretching plate 9 to move in the sliding groove 1 through the sliding assembly; the limiting assembly 1 is installed between the support plate 1 8 and the stretching plate 9 to limit the movement of the stretching plate 9; there are two support plates 2 10, and the two support plates 2 10 are horizontally fixedly installed on the workbench 1 8 and 12 respectively. The bottom of the support plate 8 and the stretching plate 9 are close to each other; there are two mounting plates 11, which are respectively set directly above the two support plates 10; there are two sets of clamping components, which are respectively installed between the two support plates 10 and the corresponding mounting plates 11, and limit components are installed between the two support plates 10 and the corresponding mounting plates 11. The clamping components are used to clamp and fix the edge of the seat cover fabric, and the limit components are used to limit the up and down movement of the mounting plates 11; there are two sets of smoothing components, which are respectively installed on the side of the two mounting plates 11 close to each other, to smooth the seat cover fabric when stretched; there are several pressure plates 12, which are arranged equidistantly below the two mounting plates 11, and buffer components are installed between the pressure plates 12 and the two mounting plates 11 to buffer the pressure plates 12 when they press the edge of the fabric.

[0033] First, place the seat cover fabric on workbench 1. Clamp one edge of the fabric between support plate 10 and mounting plate 11, ensuring the fabric is initially flat. Activate the drive assembly and adjust the position of stretching plate 9. Stretching plate 9 moves within sliding groove 1, ensuring both edges of the fabric are positioned between the corresponding support plate 10 and mounting plate 11. Next, activate the clamping assembly, causing mounting plate 11, buffer assembly, and pressure plate 12 to move downwards. Pressure plate 12 clamps the fabric edge, and the buffer assembly provides cushioning to prevent displacement and wrinkles, and to avoid damaging the fabric. The drive assembly is restarted, causing the stretching plate 9 to move horizontally away from the support plate 8, stretching the fabric. At the same time, the smoothing assembly moves with the stretching fabric to smooth it out. After smoothing out the wrinkles on the fabric, the fabric is flat and without deformation. Then, the clamping assembly drives the mounting plate 11 to move upward, and the clamping plate 12 releases its clamp on the edge of the fabric. Then, the fabric is pulled directly to the sewing machine 7. The sewing machine 7 is then started to perform the sewing operation. This achieves the simultaneous stretching of the fabric and smoothing out of wrinkles, improving the sewing quality and preventing wrinkles from reappearing during sewing.

[0034] Further reference Figures 1-3 The drive assembly includes a rotary motor 201 and a threaded rod 202. The rotary motor 201 is fixedly installed on the top of one end of the support plate 8 away from the tension plate 9. A sliding opening is provided on the top of one end of the tension plate 9. The threaded rod 202 is horizontally arranged. One end of the threaded rod 202 is fixedly connected to the output shaft of the rotary motor 201. The tension plate 9 is fitted onto the other end of the circumference of the threaded rod 202 through the sliding opening. The inner wall of the sliding opening is provided with a thread that matches the threaded rod 202.

[0035] First, place the seat cover fabric on the workbench 1. Clamp one edge of the fabric between the support plate 10 and the mounting plate 11, which are close to the support plate 8. Then, start the rotating motor 201. The output shaft of the rotating motor 201 starts to rotate, driving the threaded rod 202 to rotate synchronously. The stretching plate 9 will move horizontally along the circumference of the threaded rod 202 to adapt to the stretching requirements of seat cover fabrics of different sizes, so that both edges of the fabric are located between the support plate 10 and the mounting plate 11. After fixing the fabric with the clamping assembly, start the rotating motor 201 again to drive the stretching plate 9 to move horizontally away from the support plate 8, stretching the fabric and making it flat.

[0036] Further reference Figures 1-4The workbench 1 has two sliding grooves, one on the other side and the other in the middle. The two sliding grooves are arranged in parallel, with one of them located between the two sliding grooves. The clamping assembly includes a rotating motor 301 and a threaded rod 302. The two rotating motors 301 are fixedly installed at the bottom center of the corresponding support plate 10. The two rotating motors 301 are located in the corresponding sliding grooves. The mounting plate 11 has a sliding opening 2 at the top center. The threaded rod 302 is vertically arranged. The bottom of the threaded rod 302 is fixedly connected to the output shaft of the rotating motor 301. The mounting plate 11 is fitted onto the top of the threaded rod 302 through the sliding opening 2. The inner wall of the sliding opening 2 has a thread that matches the threaded rod 302.

[0037] When both sides of the fabric are located between the support plate 10 and the mounting plate 11, and the clamping assembly is used, the rotating motor 301 is started. The output shaft of the rotating motor 301 drives the threaded rod 302 to start rotating, which drives the mounting plate 11, the buffer assembly and the pressure plate 12 to move downward until the edges of both sides of the fabric are clamped and fixed by the pressure plate 12, so as to prevent the sides of the fabric from loosening during the stretching of the fabric, which would affect the stretching and wrinkle smoothing of the fabric.

[0038] Further reference Figures 1-4 The first limiting component includes: a limiting rod 401 and two limiting plates 402. A sliding opening 3 is provided at the top of one end of the stretching plate 9. The limiting rod 401 is horizontally set. One end of the limiting rod 401 is fixedly connected to the other side of the support plate 8. The other end of the limiting rod 401 is slidably connected to the sliding opening 3. The two limiting plates 402 are respectively fixedly installed on the other end of the threaded rod 202 and the limiting rod 401. The limiting rod 401 and the threaded rod 202 are set parallel to each other. The second limiting component includes: a limiting rod 403. A sliding opening 4 is provided at the center of the top of the mounting plate 11. The limiting rod 403 is vertically set. The bottom of the limiting rod 403 is fixedly connected to the support plate 10. The inner wall of the sliding opening 4 is slidably connected to the top of the limiting rod 403. The limiting rod 403 and the threaded rod 302 are set parallel to each other.

[0039] When the rotating motor 201 drives the threaded rod 202 to rotate and move the stretching plate 9, the limiting rod 401 effectively prevents the stretching plate 9 from shifting or rotating during the movement, ensuring that it moves stably only along the predetermined straight line direction, thus guaranteeing the accuracy and reliability of the stretching action. When the rotating motor 301 drives the threaded rod 302 to rotate and move the mounting plate 11, the limiting rod 403 restricts the mounting plate 11 to move only vertically, so that the mounting plate 11 moves precisely during the clamping of the fabric, thereby achieving the fixing operation of the fabric.

[0040] Further reference Figures 1-4The sliding assembly includes a slide rail 501 and a sliding block 502. The slide rail 501 is fixedly installed on the bottom inner wall of the sliding groove, and the sliding block 502 is slidably installed on the slide rail 501. The tops of the two sliding blocks 502 are respectively fixedly connected to the bottom ends of the tension plate 9.

[0041] When the drive assembly drives the stretching plate 9 to move, the sliding block 502 enables the stretching plate 9 to move smoothly in the horizontal direction on the slide rail 501, thereby adjusting the position of the stretching plate 9 and facilitating the subsequent stretching of the seat cover fabric.

[0042] Further reference Figure 1 , Figure 3 and Figure 6 The smoothing component includes: mounting groove plate 601 and rotating roller 602. The two mounting groove plates 601 are fixedly installed on the side of the two mounting plates 11 that are close to each other, and the rotating roller 602 is rotatably installed between the inner walls of the two ends of the mounting groove plate 601.

[0043] When the stretching plate 9 is adjusted to the appropriate position and the fabric is fixed by the clamping components, the rotating roller 602 is pressed against the fabric surface. The drive component is activated, which drives the stretching plate 9 to move horizontally away from the support plate 8. At the same time, the smoothing component moves along with it. During the stretching operation of the seat cover fabric, the fabric comes into contact with the rotating roller 602. As the stretching action proceeds, the rotating roller 602 will rotate accordingly, using its own gravity and rolling to smooth the fabric, preventing wrinkles from forming during stretching. This allows the fabric to participate in the sewing operation in a relatively flat state, achieving both stretching and smoothing of wrinkles, improving sewing quality, and preventing wrinkles from reappearing during sewing.

[0044] Further reference Figures 4-6 The buffer assembly includes: a sleeve 13, a rod 14, and a buffer spring 15. The sleeve 13 is fixedly installed at the bottom of the mounting plate 11. The rod 14 is vertically set and inserted into the corresponding sleeve 13. The buffer spring 15 is fixedly installed between the top of the rod 14 and the mounting plate 11. The bottom of the rod 14 is fixedly connected to the pressure plate 12.

[0045] When the clamping assembly is activated, the mounting plate 11, the buffer assembly, and the pressure plate 12 move downwards. As the pressure plates 12 press against the edges of the seat cover fabric, the insert rod 14 moves up and down within the sleeve 13. The buffer spring 15 is compressed accordingly. The elastic deformation of the buffer spring 15 absorbs and buffers the impact force generated by the pressing action, preventing excessive pressing force from damaging the seat cover fabric. At the same time, it allows the pressure plate 12 to press the fabric edges more stably and appropriately, ensuring that the fabric is fixed in position during sewing and facilitating smooth stretching.

[0046] Further reference Figure 3 , Figure 4 and Figure 6 Both support plates 10 have several rotating rollers 16 installed at equal intervals on one side of the top, and both mounting plates 11 have several sliding openings 5 ​​at equal intervals at the bottom, with each sliding opening 5 corresponding to one of the rotating rollers 16.

[0047] When both sides of the fabric are located between the support plate 10 and the mounting plate 11, several rotating rollers 16 will contact the fabric edges. During the process of clamping the fabric by moving the mounting plate 11 downward through the clamping assembly, the rotating rollers 16 can pass through the corresponding sliding openings 5, reducing the damage to the fabric edges during the clamping operation. After the pressure plate 12 releases the clamp on the fabric edges, the fabric is pulled directly to the sewing machine 7. The rotating rollers 16 are driven by the fabric edges to rotate, reducing the friction generated at the fabric edges when pulling the fabric, making the pulling action of the fabric smoother, preventing wrinkles when pulling the fabric, and facilitating the pulling to the bottom of the sewing machine 7.

[0048] refer to Figures 1 to 6 A sewing method for a seat cover anti-wrinkle sewing device includes the following steps:

[0049] Step 1: First, place the fabric of the seat cover flat on the workbench 1, and clamp one edge of the fabric between the support plate 10 and the mounting plate 11 near the support plate 1 8.

[0050] Step 2: Next, start the rotating motor 201. Its output shaft drives the threaded rod 202 to rotate. The stretching plate 9 moves smoothly on the slide rail 501 through the sliding block 502 and moves horizontally along the threaded rod 202, so that the two sides of the fabric are located between the support plate 10 and the mounting plate 11.

[0051] Step 3: Then start the rotating motor 301. The output shaft drives the threaded rod 302 to rotate. Under the vertical and precise movement ensured by the limit rod 403, the mounting plate 11 drives the buffer assembly and the pressing plate 12 to move downward. The insertion rod 14 moves in the sleeve 13 to compress the buffer spring 15, and finally clamps the edge of the fabric through the pressing plate 12.

[0052] Step 4: Then, start the rotating motor 201 again to drive the stretching plate 9 to stretch the fabric away from the support plate 8. During the stretching, the rotating roller 602 relies on its own rolling and weight to move with the fabric and smooth it out. The fabric is stretched and flattened, and the smoothing component prevents wrinkles from appearing when stretching the fabric.

[0053] Step 5: After stretching, the clamping assembly moves the mounting plate 11 upward to release the pressure plate 12. Then, the fabric is pulled so that its edge drives the rotating roller 16 to rotate, pulling the fabric under the sewing machine 7. The sewing machine 7 is then started to perform the sewing operation. The rotating roller 16 is driven by the edge of the fabric to rotate, reducing the friction generated at the edge of the fabric when pulling the fabric, making the pulling action of the fabric smoother and preventing wrinkles from appearing when pulling the fabric.
