Description

Technical Field

[0001] This utility model relates to the field of automated control technology for fabric cutting, and in particular to an automatic fabric cutting device. Background Technology

[0002] Clothing is made by cutting fabric, and there are three main cutting methods: flat pattern cutting, draping, and pattern making. Flat pattern cutting involves creating a flat pattern based on human body dimensions and using a short-length cutting method. Draping involves cutting directly from the human body to create garment pieces that conform to the body's curves. Pattern making uses the shape obtained from draping and then cuts it according to the desired ease of fit. Due to the differences in the shape of the human torso, men's and women's clothing require different cutting methods to ensure a good fit and aesthetic appeal. Furthermore, based on production scale, cutting methods are also divided into batch cutting and single-piece cutting.

[0003] Regardless of the method used, the first step is to divide the large piece of fabric into individual sizes, followed by rough cutting. Typically, tailors measure on a table and mark the positions with chalk before cutting. However, because the fabric is not fixed on the table, deviations can easily occur during measurement and cutting, affecting accuracy. When garment factories engage in mass production, manually measuring and marking each piece of fabric is inefficient and lacks precision. Utility Model Content

[0004] The main purpose of this invention is to provide an automatic fabric cutting device, which aims to improve the efficiency and accuracy of fabric cutting and garment sewing.

[0005] To achieve the above objectives, the present invention provides an automatic fabric cutting device, comprising:

[0006] A frame, on which a worktable is provided for supporting the fabric;

[0007] The jigsaw puzzle module includes an electronic control board and a signal receiving component, which can receive at least one cut pattern uploaded from the outside and intelligently integrate the cut pattern to form a pattern to be cut.

[0008] The pressure stabilizing module includes a pressure block and a telescopic rod. One end of the telescopic rod is connected to the frame, and the other end is connected to the pressure block, so that the pressure block can move closer to or further away from the worktable.

[0009] The cutting module includes a robotic arm, a cutting head, and a displacement bracket. One end of the robotic arm is connected to the cutting head, and the other end is connected to the displacement bracket. The robotic arm can extend and retract in the height direction to move the cutting head closer to or further away from the worktable. The robotic arm can also move along a first direction on the displacement bracket, which is parallel to the working surface of the worktable. At least one of the displacement bracket and the worktable can rotate around the central axis of the worktable. The electronic control board is electrically connected to the cutting module to enable the cutting head to cut out a cutting pattern on the fabric.

[0010] In one embodiment, the cutting module includes a first moving component and a second moving component. The electronic control board is electrically connected to the first moving component and the second moving component. The first moving component is disposed between the displacement bracket and the robotic arm to drive the robotic arm to move along the first direction. The second moving component is disposed at the bottom of the displacement bracket to drive the displacement bracket to move along the second direction. The second direction is horizontally arranged with the plane containing the first direction and intersects with the first direction.

[0011] In one embodiment, the displacement support includes a first support arm, a second support arm, and a cantilever frame. The first support arm and the second support arm are respectively disposed on opposite sides of the workbench and support the cantilever frame. A first moving component is disposed on the cantilever frame and extends along the extension direction of the cantilever frame. The first moving component is drivenly connected to the robotic arm, and the first direction is configured as the extension direction of the cantilever frame.

[0012] In one embodiment, the second moving component includes two slide rails and a second driving member. The two slide rails are respectively disposed at the bottom ends of the first support arm and the second support arm and extend along the second direction. The second driving member drives the first support arm and the second support arm to move along the slide rails so that the displacement bracket has a working position and an avoidance position. In the working position, the cutting head is located above the worktable; in the avoidance position, the cutting head is located outside the worktable.

[0013] In one embodiment, the displacement bracket further includes a support frame, which is disposed below the workbench and supports the first support arm and the second support arm, and the slide rail is disposed on the support frame.

[0014] In one embodiment, the automatic fabric cutting device further includes a second rotating component, which includes a second annular slide rail and a second rotating drive. The central axis of the second annular slide rail is aligned with the central axis of the worktable. The supporting frame is slidably connected to the second annular slide rail. The second rotating drive is electrically connected to the electronic control board. The second rotating drive drives the slide rail to rotate around the central axis of the worktable.

[0015] In one embodiment, the automatic fabric cutting device further includes a first rotating component, which is electrically connected to the electronic control board and disposed between the frame and the worktable, so as to drive the worktable to rotate around its own central axis.

[0016] In one embodiment, the first rotating assembly includes a first annular slide rail and a first rotating drive member. The lower side of the worktable is provided with a sliding protrusion, which is slidably connected to the first annular slide rail. The first rotating drive member is electrically connected to the electronic control board to drive the worktable to rotate.

[0017] In one embodiment, the worktable has a circular cross-sectional shape.

[0018] In one embodiment, the automatic fabric cutting device further includes an image recognition module, which is located above the workbench and includes a camera. The camera is electrically connected to the electronic control board and is oriented towards the workbench to recognize cutting patterns.

[0019] In one embodiment, the first moving component includes a linear motor.

[0020] In this invention, fabric to be cut is placed on a workbench. The fabric can be one piece or multiple pieces. A weight is then placed on the workbench to press the fabric firmly, preventing movement between the workbench and the fabric, or between different pieces of fabric, during cutting, thus avoiding affecting cutting accuracy. The user can receive uploaded drawing information via a signal receiving component. When multiple cutting patterns are uploaded, patterns that can be combined are organized into a single pattern to be cut, while patterns that cannot be combined are cut separately. The output is the pattern to be cut. When only one pattern is uploaded, it is directly output as the pattern to be cut. The control board then moves the robotic arm on the displacement support, extending it to bring the cutting head closer to the worktable. The displacement support or worktable then rotates, and the robotic arm moves relative to the support in a first direction. The cutting head moves along the outline of the pattern to be cut on the worktable, cutting the fabric into the desired pattern. This achieves automatic fabric cutting, improving both efficiency and accuracy. Furthermore, it eliminates the need to sew multiple pieces of fabric together during garment sewing, simplifying the process and effectively improving efficiency and accuracy. It also simplifies the process of sewing two pieces of fabric into one, significantly increasing sewing speed. When the fabric being cut is a thin fabric, multiple holes can be made along the edge of the original cutting pattern on the fabric to be cut using a thread-cutting process. Then, the reinforcing strip with thread holes is sewn along the edge of the original cutting pattern. During the sewing process, the thread bundle can pass through the holes made by the thread-cutting process on the fabric and the thread holes of the reinforcing strip in turn, and the reinforcing strip is sewn onto the fabric to complete the reinforcement of the garment.

[0032] This utility model proposes an automatic fabric cutting device.

[0033] Please see Figure 1 In one embodiment of this utility model, the automatic fabric cutting device includes:

[0034] The frame 100 has a worktable 11 on it for supporting the fabric.

[0035] The jigsaw puzzle module includes an electronic control board and a signal receiving component, which can receive at least one cut pattern uploaded from the outside and intelligently integrate the cut pattern to form a pattern to be cut.

[0036] The pressure stabilizing module includes a pressure block and a telescopic rod. One end of the telescopic rod is connected to the frame 100, and the other end is connected to the pressure block, so that the pressure block can move closer to or further away from the worktable 11.

[0037] The cutting module 300 includes a robotic arm 31, a cutting head 32, and a displacement bracket 33. One end of the robotic arm 31 is connected to the cutting head 32, and the other end is connected to the displacement bracket 33. The robotic arm 31 can extend and retract in the height direction to move the cutting head 32 closer to or further away from the worktable 11. The robotic arm 31 can also move along a first direction on the displacement bracket 33. The first direction is parallel to the working surface of the worktable 11. At least one of the displacement bracket 33 and the worktable 11 can rotate around the central axis of the worktable 11. The control board is electrically connected to the cutting module 300 so that the cutting head 32 can cut out a cutting pattern on the fabric.

[0038] In this utility model's technical solution, fabric to be cut is placed on the workbench 11. The fabric can be one piece or multiple pieces. Then, a weight is placed on the workbench 11 to press the fabric firmly against it, preventing movement between the workbench and the fabric, or between different pieces of fabric, during cutting, thus avoiding affecting the cutting accuracy. The user can receive uploaded drawing information via a signal receiving component. When multiple cutting patterns are uploaded, the system identifies the patterns that can be combined into one cutting pattern, while patterns that cannot be combined are output separately as cutting patterns. When only one cutting pattern is uploaded, the cutting pattern is directly output as the pattern to be cut. Then, the electronic control board controls the robotic arm 31 to move on the displacement support 33 and extend the robotic arm 31 so that the cutting head 32 is close to the worktable 11. Then, the displacement support 33 or the worktable 11 rotates, and the robotic arm 31 moves relative to the displacement support 33 in the first direction. The cutting head 32 can move along the outline of the pattern to be cut on the worktable 11, cutting the fabric on the worktable 11 into the pattern to be cut. That is, automatic cutting of fabric can be realized, improving cutting efficiency and cutting accuracy. Moreover, in the process of garment sewing, it can eliminate the need to sew multiple pieces of fabric together, simplifying the steps of garment sewing and effectively improving the efficiency and accuracy of garment sewing. In the process of sewing, it simplifies the step of workers sewing two pieces of fabric into one piece of fabric, effectively improving the sewing speed. When the fabric being cut is a thin fabric, multiple holes can be made along the edge of the original cutting pattern on the fabric to be cut using a thread-cutting process. Then, the reinforcing strip with thread holes is sewn along the edge of the original cutting pattern. During the sewing process, the thread bundle can pass through the holes made by the thread-cutting process on the fabric and the thread holes of the reinforcing strip in turn, and the reinforcing strip is sewn onto the fabric to complete the reinforcement of the garment.

[0039] In one embodiment, the cutting module 300 includes a first moving component and a second moving component 35. An electronic control board is electrically connected to the first and second moving components 35. The first moving component is located between the displacement support 33 and the robotic arm 31 to drive the robotic arm 31 to move along a first direction. The second moving component 35 is located at the bottom of the displacement support 33 to drive the displacement support 33 to move along a second direction. The second direction is horizontally aligned with and intersects the plane containing the first direction. That is, the cutting head 32 can move to any position on the worktable 11 to cut the fabric without rotating the displacement support 33 and / or the worktable 11. Furthermore, when the cutting pattern is complex, the first and second moving components 35 can be activated simultaneously, causing the displacement support 33 and / or the worktable 11 to rotate. When the cutting head 32 frequently changes direction, by changing the driving component that drives the cutting head 32, the flexibility and adaptability of cutting are increased, while the workload of the first and second moving components 35, as well as the driving component that drives the displacement support 33 and / or the worktable 11 to rotate, is reduced, thus extending its service life. In other embodiments, only the first moving component may be provided.

[0040] In one embodiment, the displacement support 33 includes a first support arm 331, a second support arm 332, and a cantilever beam 333. The first support arm 331 and the second support arm 332 are respectively disposed on opposite sides of the worktable 11 and support the cantilever beam 333. A first moving component is disposed on the cantilever beam 333 and extends along the extension direction of the cantilever beam 333. The first moving component is drivenly connected to the robotic arm 31, and the first direction is configured as the extension direction of the cantilever beam 333. Further, the first moving component includes a linear motor. The high efficiency, high precision, and fast response of the linear motor make the movement of the robotic arm 31 more precise and faster, improving the efficiency and quality of cutting. In other embodiments, the first moving component may also include a linear slide rail 351 and a drive motor, with the push rod of the drive motor pushing the robotic arm 31 to move on the linear slide rail 351.

[0041] In one embodiment, the second moving component 35 includes two slide rails 351 and a second driving member. The two slide rails 351 are respectively disposed at the bottom ends of the first support arm 331 and the second support arm 332, and extend along a second direction. The second driving member drives the first support arm 331 and the second support arm 332 to move along the slide rails 351, so that the displacement bracket 33 has a working position and a clearance position. In the working position, the cutting head 32 is located above the worktable 11, and the second driving member can drive the cutting head 32 to move along the second direction and cooperate with the first moving component to make the cutting head 32 move in a curve on the worktable 11. In the clearance position, the cutting head 32 is located outside the worktable 11 to provide sufficient space for the user to move when changing fabric or paper patterns, and to avoid the cutting head 32 scratching the user. In other embodiments, the clearance position may not be provided.

[0042] In one embodiment, the displacement bracket 33 further includes a support frame 334, which is located below the worktable 11 and supports the first support arm 331 and the second support arm 332. A slide rail 351 is disposed within the support frame 334. This provides stable support for the first support arm 331 and the second support arm 332, making the slide rail 351 more stable and less prone to deformation, thus increasing the support stability and durability of the displacement bracket 33. In other embodiments, the support frame 334 may not be included.

[0043] In one embodiment, the automatic fabric cutting device further includes a first rotating assembly 400, which is electrically connected to the control board and disposed between the frame 100 and the worktable 11, enabling the worktable 11 to rotate around its central axis. The supporting frame 334 can rotate around the central axis of the worktable 11, providing the device with additional rotational freedom, allowing the robotic arm 31 to cut the fabric at different angles, making the cutting more flexible and facilitating the cutting blade to cut curved patterns on the fabric. Furthermore, the first rotating assembly 400 includes a first annular slide rail 41 and a first rotating drive member 42. The lower side of the worktable 11 is provided with a sliding protrusion 111, which is slidably connected to the first annular slide rail 41. The first rotating drive member 42 is electrically connected to the control board to drive the worktable 11 to rotate, making the rotation of the worktable 11 more precise and controllable. In another embodiment, the automatic fabric cutting device further includes a second rotating assembly, which comprises a second annular slide rail 351 and a second rotating drive. The central axis of the second annular slide rail 351 is aligned with the central axis of the worktable 11. The supporting frame 334 is slidably connected to the second annular slide rail 351. The second rotating drive is electrically connected to the control board and drives the slide rail 351 to rotate around the central axis of the worktable 11. Furthermore, both the first rotating drive 42 and the second rotating drive are configured as servo motors. Servo motors have high rotational accuracy, which can effectively improve the cutting precision.

[0044] In one embodiment, the worktable 11 has a circular cross-sectional shape. This makes the worktable 11 more stable when rotating and also facilitates the placement and cutting of fabric. In other embodiments, the worktable 11 may also have a square cross-sectional shape.

[0045] In one embodiment, the automatic fabric cutting device further includes an image recognition module 200, which is located above the worktable 11 and includes a camera electrically connected to the control board. The camera is positioned facing the worktable 11 to recognize cutting patterns. The camera of the image recognition module 200 captures images of the worktable 11 and can recognize the shape of the cutting pattern placed on the fabric pattern, processing the cutting pattern on the pattern into a pattern to be cut and uploading it to the control board. At this time, a weight block presses the pattern firmly onto the fabric. The image recognition module 200 simplifies the operation of the automatic fabric cutting device and reduces the difficulty of operation, making it easy for users to operate. In other embodiments, the image recognition module 200 may not be included.

[0046] In the garment manufacturing industry, pattern making and sewing are crucial processes. However, traditional pattern making and sewing methods involve many tedious steps, especially when dealing with complex curves and splicing, which is not only time-consuming and labor-intensive but also requires a high level of skill from the operator.

[0053] (2) The operation has been simplified, greatly reducing the difficulty of operation and making the entire production process smoother and more efficient.

[0054] 3. Enhance design aesthetics and precision

[0055] (1) It can better control the curvature and splicing position, ensuring that the finished product meets the design requirements.

[0056] (2) It reduces errors caused by human factors and improves the quality and consistency of finished products.

[0057] 4. Significantly improves production efficiency

[0058] (1) By simplifying the processes in the upstream and downstream links, the improved yarn-making technology has significantly improved production efficiency. Enterprises can complete more orders in a shorter time, thereby enhancing their market competitiveness.

[0059] And it brings the following beneficial effects:

[0060] (1) Improved production efficiency: By simplifying the pattern making and sewing process, the overall production efficiency has been improved by more than 30%.

[0061] (2) Product quality improvement: Due to the reduction of errors caused by human factors, the quality of finished products has been significantly improved.

[0062] (3) Cost reduction: The simplified process reduces the reliance on auxiliary tools and manual labor, thus reducing production costs.
