Detailed Implementation

[0016] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the invention and not intended to limit it. Furthermore, it should be noted that, for ease of description, the accompanying drawings show only the parts relevant to the present invention, and not all of the structures.

[0017] This invention provides a pattern sewing method for performing pattern sewing. This pattern sewing method can be performed using a pattern sewing machine. The pattern sewing machine integrates a parametric sewing system, which includes a punching process and a sewing process. The punching process is a process of forming holes in the fabric, used to punch holes in the fabric. The sewing process is a process of forming patterns on the fabric, used to form a preset pattern on the fabric. Figure 1 This is a flowchart illustrating a pattern sewing method provided in an embodiment of the present invention. Figure 1 As shown, the pattern sewing method includes: S110, Obtain the sewing parameters for the pattern.

[0018] Specifically, the sewing parameters for the pattern can be externally input parameters. For example, Figure 2 This is a schematic diagram of the structure of a display panel for a sewing machine provided in an embodiment of the present invention. Figure 2 As shown, the display panel includes a setting box for pattern sewing parameters. Before performing pattern sewing, the user can input the corresponding sewing parameters in the display panel, allowing the sewing machine to acquire these parameters. For example, if the pattern sewing machine includes a pass-through process and a sewing process, then the sewing parameters include pass-through parameters and sewing parameters. The pass-through parameters define the pattern sewing process within the pass-through process, and the sewing parameters define the pattern sewing process within the sewing process.

[0019] S120. After determining the sewing sequence of the pattern, sew the pattern according to the sewing parameters and the sewing sequence.

[0020] Specifically, the sewing sequence for a pattern includes the order in which the over-stitching and sewing processes are executed. This sequence can be preset within the sewing machine. Different sewing sequences correspond to different application scenarios. These scenarios can include the type of fabric and the shape of the pattern. During pattern sewing, the user can select the preset sewing sequence based on the application scenario. For example, such as... Figure 2As shown, the sewing machine's display panel displays sewing sequence parameters, allowing users to select a pre-set sewing sequence. The sewing process is then executed according to this sequence and parameters, enabling the selection of appropriate sequences based on different fabrics and patterns. This improves the success rate of pattern sewing and makes the method applicable to various scenarios, broadening its scope of use. It also eliminates the need for manual adjustments to the sewing sequence based on the application, increasing efficiency, reducing the technical requirements for manual sewing, minimizing fabric waste, and lowering production costs. Furthermore, the sewing parameters can be customized to adjust the pattern's shape, significantly enhancing its flexibility.

[0021] For example, when the fabric used for pattern sewing is stiff, thick leather, and complex patterns requiring precise pre-planning of hole positions are needed, or when mass production is required and high consistency of finished products is demanded, the sewing sequence for the pattern can be a punching process followed by a sewing process. When the fabric used for pattern sewing is extremely soft, easily deformed, and the center alignment of the punching process is critical, the sewing sequence for the pattern can be a sewing process followed by a punching process.

[0022] The technical solution of this embodiment, by acquiring the sewing parameters of the pattern and determining the sewing sequence of the pattern, performs pattern sewing according to the sewing parameters and the sewing sequence. This allows for the selection of a suitable sewing sequence based on different fabrics and patterns, achieving integrated punching and sewing operations, simplifying the production process, improving production efficiency and the pass rate of pattern sewing, and making the pattern sewing method applicable to different application scenarios, meeting the sewing needs of different fabrics, and expanding the scope of application of the pattern sewing method. It has broad applicability and promotional value. Simultaneously, it avoids manual adjustment of the sewing process according to the application scenario, improving the efficiency of pattern sewing, reducing the technical requirements of manual labor in the pattern sewing process, reducing the risk of fabric waste, and lowering production costs. Moreover, the sewing parameters of the pattern can be personalized to adjust the shape of the pattern, significantly improving the flexibility of the pattern.

[0023] In some embodiments, the pattern sewing machine includes a preset coordinate system; the preset coordinate system is a two-dimensional coordinate system, which includes an origin and XY axes. After the pattern sewing machine is started, the needle drop point of the pattern sewing machine is placed at the origin of the preset coordinate system by default. Sewing parameters include pattern parameters; the pattern parameters include at least the preset origin coordinates and the idle feed speed. The pattern parameters are those relevant to the pattern sewing process. (Reference) Figure 2The pattern parameters include preset origin coordinates and feed speed. The preset origin coordinates are externally input parameters, serving as a reference point set by the user according to requirements, and acting as the center point of the pattern. For example, during pattern sewing, the preset coordinate system origin corresponds to a mark on the fabric. To avoid damaging or covering the mark, the preset coordinate system origin cannot be used as the center point of the pattern. In this case, the user can reset the coordinates of the pattern's center point in the preset coordinate system according to the shape of the pattern and the customer's mark, thus resetting the preset origin coordinates and ensuring the integrity and visibility of the mark. The feed speed is the speed at which the transition needle runs during pattern sewing. For example, when the origin of the preset coordinate system moves to the preset origin coordinates, the pattern sewing machine does not perform the overpass or sewing processes; only the position of the needle drop point moves. The speed at which the needle drop point moves at this time is the feed speed.

[0024] Figure 3 This is a flowchart illustrating another pattern sewing method provided in an embodiment of the present invention. (See attached diagram.) Figure 3 As shown, the pattern sewing method includes: S210, Obtain the sewing parameters for the pattern.

[0025] S220, Control the opening of the stitching function of the pattern sewing machine.

[0026] For details, please refer to [link / reference]. Figure 2 The display panel of the fancy sewing machine also includes a punching function switch, used to control the on / off state of the integrated punching and sewing function. When the punching function switch is on, the fancy sewing machine can automatically and continuously perform the punching and sewing processes. When the punching function switch is off, the fancy sewing machine cannot automatically and continuously perform the punching and sewing processes. In this embodiment, the punching function switch can be controlled to be on, allowing the fancy sewing machine to automatically and continuously perform the punching and sewing processes.

[0027] S230. After placing the center point of the pattern at the origin of the preset coordinate system, the origin of the preset coordinate system is sent to the preset origin coordinates by air according to the air delivery speed.

[0028] Specifically, after the pattern sewing machine is started, the center point of the pattern is placed at the origin of the preset coordinate system by default. After the punching function is turned on, the origin of the preset coordinate system is moved to the preset origin coordinates, so that the center point of the pattern is placed at the preset origin coordinates. When there are other patterns that need to be exposed at the origin of the preset coordinate system, this can prevent the pattern at the origin position from being affected during the pattern sewing process, thus meeting the customer's needs.

[0029] S240. After determining the sewing sequence of the pattern, sew the pattern according to the sewing parameters and the sewing sequence.

[0030] In some embodiments, the sewing process includes an arc stitch process and a zigzag stitch process, corresponding to the arc stitch and zigzag stitch of the pattern, respectively, enabling the sewing process to achieve complex patterns. For example, a chrysanthemum pattern can be achieved through the arc stitch process and the zigzag stitch process. In the sewing process, the arc stitch process can be performed first, followed by the zigzag stitch process. The sewing parameters also include an initial start point, arc stitch parameters, zigzag stitch parameters, and overpass parameters; the arc stitch parameters define the pattern sewing process during the arc stitch process, the zigzag stitch parameters define the pattern sewing process during the zigzag stitch process, and the overpass parameters define the pattern sewing process during the overpass process. The initial start point defines the start point of the pattern sewing. In the sewing process, when the arc stitch process takes precedence over the zigzag stitch process, the needle drop point can be fed empty from the initial start point to the first start point, so that the arc stitch process is performed first, followed by the zigzag stitch process. The process involves a transition between the circular stitch and the zigzag stitch. Specifically, the end point of the circular stitch transitions to the second starting point of the zigzag stitch. The end point of the circular stitch is the starting point of the last circular stitch, and the second starting point of the zigzag stitch can be determined based on the outer diameter of the zigzag stitch in the zigzag stitch parameters. For example, the x-coordinate of the second starting point of the zigzag stitch is the x-coordinate of the origin of the preset coordinate system plus the outer diameter of the zigzag stitch, and the y-coordinate is the origin of the preset coordinate system. The punching parameters include punch coordinates, used to define the punching position. The sewing process sequence includes the punching process followed by the sewing process. When the sewing process includes both the circular stitch and the zigzag stitch, the execution order is: first the circular stitch, then the zigzag stitch. During pattern sewing, users can set preset coordinate origins and punch coordinates, allowing dynamic adjustment of the starting point of the pattern sewing to achieve precise alignment between punching and sewing.

[0031] Figure 4 This is a flowchart illustrating another pattern sewing method provided in an embodiment of the present invention. (See attached diagram.) Figure 4 As shown, before performing pattern sewing, the user selects the sewing sequence as punching-sewing when the fabric is stiff, thick leather, the fabric requires precise pre-planning of complex patterns with hole positions, or when mass production is required and high consistency of finished products is demanded. Pattern sewing methods include: S310, Obtain the sewing parameters for the pattern.

[0032] S320, control the opening of the stitching function on the pattern sewing machine.

[0033] S330. After placing the center point of the pattern at the origin of the preset coordinate system, the origin of the preset coordinate system is sent to the preset origin coordinates by air according to the air delivery speed.

[0034] S340. Transfer the origin of the preset coordinate system from the preset origin coordinates to the overshoot coordinates.

[0035] Specifically, when the sewing process sequence is to first perform the punching process, after the center point of the pattern corresponds with the preset origin coordinates, the origin of the preset coordinate system is sent from the preset origin coordinates to the punching coordinates, so that the punching process is performed at the punching coordinates, thereby forming a through hole at the preset punching position.

[0036] S350, Perform the overshooting process according to the overshooting parameters.

[0037] Specifically, such as Figure 2 As shown, the over-punching parameters also include punching delay and sewing sequence; the punching delay can be the delay time after the pressing or lifting action during the over-punching process. For example, the punching delay can be 500ms. During the over-punching process, punching is performed at the punching position, followed by a punching delay, then a punching lift, and then another punching delay. The sewing sequence is the order in which the over-punching process is performed at multiple through-hole positions when the pattern sewing method includes multiple through-holes. The over-punching parameters can be externally input parameters. After determining the over-punching parameters, the over-punching process is performed according to the parameters to complete the through-hole formation process in the pattern sewing process.

[0038] S360. Transfer the origin of the preset coordinate system from the overshoot coordinate system to the initial seam starting point.

[0039] Specifically, after the over-stitching process is completed, the origin of the preset coordinate system is moved from the over-stitching coordinate system to the initial starting point, so that the sewing process begins at the initial starting point, and the pattern is formed in the preset position. The circular seam has a first starting point, which defines the starting position of the circular seam. When the circular seam process is performed first, followed by the zigzag seam process, during the sewing process, the needle drop point can be moved from the initial starting point to the first starting point of the circular seam to begin the circular seam process.

[0040] S370. Perform the arc seam operation according to the arc seam parameters and the zigzag seam operation according to the zigzag seam parameters.

[0041] Specifically, after being fed from the origin of the preset coordinate system to the initial sewing point via the overpass coordinate system, the circular sewing process can be executed first according to the circular sewing parameters, and then the zigzag sewing process can be executed according to the zigzag sewing parameters and the desired stitch count. Finally, the thread is trimmed to complete the punching and pattern sewing.

[0042] For example, such as Figure 2As shown, the pattern parameters also include the expected number of stitches and the sewing direction. The expected number of stitches is the total number of stitches required during the pattern sewing process. The sewing direction is the direction in which the sewing path extends. The expected number of stitches and the sewing direction can be externally input parameters. The circular seam parameters can also include the circular seam diameter, the number of circular seam loops, and the circular seam stitch length. The circular seam diameter determines the circular seam radius. When there are at least two circular seams, the circular seam diameter includes the diameter of each circular seam, and the number of circular seam loops includes the number of loops for each circular seam. The stitch length for different circular seams can be equal. For example, as shown... Figure 2 As shown, the circular seam includes two seams, namely bottom seam 1 and bottom seam 2. The parameters for the circular seam include the diameter of bottom seam 1, the number of turns of bottom seam 1, the diameter of bottom seam 2, and the number of turns of bottom seam 2. The stitch length of the circular seam is the same as the stitch length of bottom seam 1 and bottom seam 2. The parameters for the zigzag seam may also include the inner diameter of the zigzag seam, the outer diameter of the zigzag seam, and the number of turns of the zigzag seam. Performing the circular seam process based on the circular seam parameters and performing the zigzag seam process based on the zigzag seam parameters include: Based on the pattern parameters, circular seam parameters, and zigzag seam parameters, the needle placement coordinates of each stitch in the circular seam process and the needle placement coordinates of each stitch in the zigzag seam process are determined using a pattern trajectory algorithm.

[0043] Specifically, the pattern sewing machine is equipped with a pattern trajectory algorithm, which is used to determine the needle coordinates of each stitch in the circular stitch process and the needle coordinates of each stitch in the zigzag stitch process based on the pattern parameters, circular stitch parameters, and zigzag stitch parameters.

[0044] Based on the stitch coordinates of each stitch in the pattern, adjacent stitch points are connected using a drawing function.

[0045] Specifically, the pattern sewing machine has a built-in drawing function. After determining the stitch coordinates of each stitch, the drawing function can be called based on the arc seam parameters to connect adjacent stitch points and execute the arc seam and zigzag seam processes. After executing the arc seam process, the pattern sewing machine can determine the remaining stitches for the zigzag seam process based on the desired stitch count, the number of stitches in the arc seam process, and the number of transition stitches from the arc seam to the zigzag seam process. Then, based on the remaining stitches and the zigzag seam parameters, the machine calculates the number of vertices and the coordinates of each vertex in the zigzag seam process, which are the stitch coordinates of each stitch in the zigzag seam process. Finally, the drawing function is called to connect adjacent stitch points and execute the zigzag seam process.

[0046] In some embodiments, when the sewing process further includes a reinforcing seam process, the sewing parameters further include reinforcing seam parameters; the reinforcing seam parameters include the initial reinforcing stitch count, the final reinforcing stitch count, and the reinforcing stitch distance; performing the circular seam process according to the circular seam parameters and performing the zigzag seam process according to the zigzag seam parameters further includes: Based on the pattern parameters, arc seam parameters, zigzag seam parameters, and reinforcement seam parameters, the needle landing coordinates of each stitch in the arc seam process, the needle landing coordinates of each stitch in the zigzag seam process, and the needle landing coordinates of each stitch in the reinforcement seam process are determined using a pattern trajectory algorithm.

[0047] Specifically, when the sewing process includes a reinforcing seam process, the reinforcing seam process may include at least one of a starting reinforcing seam process and a ending reinforcing seam process. The starting reinforcing seam process can be part of a circular arc seam process. In this case, the regular sewing portion of the circular arc seam process can be defined as the first regular sewing process. The circular arc seam process then includes both the first regular sewing process and the starting reinforcing seam process. Both the starting reinforcing seam process and the first regular sewing process are used to form the circular arc seam, and the starting reinforcing seam process takes precedence over the first regular sewing process. The stitch lengths of the starting reinforcing seam process and the first regular sewing process are different. The ending reinforcing seam process and the zigzag seam process are used to achieve the zigzag seam. The ending reinforcing seam process is performed after the zigzag seam process. After the zigzag seam path is formed in the zigzag seam process, the ending reinforcing seam process is performed between the first and second stitches of the zigzag seam path to achieve the ending reinforcing seam. After determining the pattern parameters, circular seam parameters, zigzag seam parameters, and reinforcement seam parameters, the needle coordinates of each stitch in the first regular sewing process, the zigzag seam process, and the reinforcement seam process can be determined using the pattern trajectory algorithm. Then, based on the needle coordinates of each stitch in the pattern, adjacent needle points are connected using a drawing function to realize the sewing of the pattern.

[0048] In some embodiments, the sewing process sequence may further include a sewing process followed by a flushing process. Figure 5 This is a flowchart illustrating another pattern sewing method provided in an embodiment of the present invention. (See attached diagram.) Figure 5 As shown, before performing pattern sewing, if the fabric being patterned is an extremely soft and easily deformed material, and the center alignment of the holes requires a high degree of precision (near-perfect), or if it is used to produce experimental products, and the user selects a sewing sequence that also includes a sewing process followed by a punching process, then the pattern sewing method includes: S410, Obtain the sewing parameters for the pattern.

[0049] S420: Controls the opening of the stitching function on the pattern sewing machine.

[0050] S430. After placing the center point of the pattern at the origin of the preset coordinate system, the origin of the preset coordinate system is sent to the preset origin coordinates by air according to the air delivery speed.

[0051] S440. Transfer the origin of the preset coordinate system from the preset origin coordinates to the first starting point of the arc seam.

[0052] Specifically, after the center point of the pattern corresponds to the preset origin coordinates, the origin of the preset coordinate system is sent from the preset origin coordinates to the first starting point of the arc seam, so that the sewing process starts to execute the arc seam process and the zigzag seam process in sequence at the first starting point, so that the pattern is formed in the preset position.

[0053] S450, Perform the circular seam operation according to the circular seam parameters and the zigzag seam operation according to the zigzag seam parameters.

[0054] Specifically, such as Figure 2 As shown, after determining the parameters for the circular seam, zigzag seam, and punching, the drawing function can be called first based on the circular seam parameters to connect adjacent needle points and execute the circular seam operation, thus completing the circular seam sewing. Then, the drawing function can be called again based on the zigzag seam parameters to connect adjacent needle points and execute the zigzag seam operation, thus completing the zigzag seam sewing. Finally, the thread is cut to complete the pattern sewing.

[0055] S460, Move the origin of the preset coordinate system to the overshoot coordinate.

[0056] Specifically, after the sewing process is completed, the origin of the preset coordinate system is moved from the end point of the sewing process to the over-punching coordinate, so that the over-punching process is performed at the over-punching coordinate, thereby forming a through hole at the preset punching position.

[0057] S470. Perform the overshooting process according to the overshooting parameters.

[0058] Specifically, the over-punching process may include pressing down the punching position, then delaying the punching time, then lifting the punching position, and then delaying the punching time again to complete the punching.

[0059] In some embodiments, the sewing sequence further includes an arc-shaped seam step, a punching step, and a zigzag seam step. Before performing pattern sewing, the user, based on the difficulty of pattern sewing operations (e.g., sewing a portion first allows for better observation of the overall pattern effect, and then determining the optimal punching position, which is easier than a sewing step-punching step), selects the arc-shaped seam step-punching step-zigzag seam step as the sewing sequence. In this case, the pattern sewing method can first perform the arc-shaped seam step in the sewing sequence, then perform the punching step, and finally perform the zigzag seam step. Specifically, Figure 6 This is a flowchart illustrating another pattern sewing method provided in an embodiment of the present invention. (See attached diagram.) Figure 6 As shown, the fancy sewing methods include: S510, Obtain the sewing parameters for the pattern.

[0060] S520, control the opening of the stitching function of the pattern sewing machine.

[0061] S530. After placing the center point of the pattern at the origin of the preset coordinate system, the origin of the preset coordinate system is sent to the preset origin coordinates by air according to the air delivery speed.

[0062] S540. Transfer the origin of the preset coordinate system from the preset origin coordinates to the first starting point of the arc seam.

[0063] S550, Perform the arc seam process according to the arc seam parameters.

[0064] S560, Move the origin of the preset coordinate system to the overshoot coordinate.

[0065] S570. Perform the overshooting process according to the overshooting parameters.

[0066] S580. Move the origin of the preset coordinate system to the initial seam starting point.

[0067] Specifically, after the over-punching process is completed, the origin of the preset coordinate system is sent to the initial starting point so that the subsequent zigzag stitching process has a reference position.

[0068] S590. Perform the zigzag seam procedure according to the zigzag seam parameters.

[0069] Specifically, after the needle drop point is located at the initial starting point, the needle drop point can be directly moved to the second starting point of the zigzag seam according to the outer diameter of the zigzag seam in the zigzag seam parameters. Then, after the needle drop point is located at the second starting point of the zigzag seam, the zigzag seam process can continue to be performed according to the zigzag seam parameters.

[0070] Continue to refer to Figure 6 After the circular stitching process is completed, the thread can be trimmed before the punching process. Similarly, after the zigzag stitching process is completed, the thread can be trimmed to finish punching and sewing the decorative stitches.

[0071] In some embodiments, the pattern includes at least two through holes; the punching process includes a first punching process and a second punching process; the first punching process and the second punching process are respectively used to perform the punching process of some through holes. At this time, the through hole process performed by the first punching process and the second punching process corresponds to the punching process of all through holes, that is, the first punching process and the second punching process complete the punching process of all through holes. The sewing process sequence also includes the arc seam process - the first punching process - the zigzag seam process - the second punching process. Before the pattern sewing is performed, the user selects the sewing process sequence as the arc seam process - the first punching process - the zigzag seam process - the second punching process according to the area and hardness of the fabric (for example, when the fabric is a large fabric or a soft fabric, it is necessary to punch holes in stages to avoid the subsequent misalignment of the sewing holes due to changes in material tension after punching all holes at once). In this case, the pattern sewing method can first perform the arc seam process in the sewing process, then perform the first punching process, then perform the zigzag seam process, and finally perform the second punching process. Specifically, Figure 7 This is a flowchart illustrating another pattern sewing method provided in an embodiment of the present invention. (See attached diagram.) Figure 7 As shown, the fancy sewing methods include: S610, Obtain the sewing parameters for the pattern.

[0076] S660, Move the origin of the preset coordinate system to the overshoot coordinate.

[0077] S670. Perform the first overshooting operation according to the overshooting parameters.

[0078] Specifically, after the first punching process, the pattern sewing completes the punching process for some of the holes. This avoids the phenomenon of poor alignment accuracy during subsequent punching due to changes in fabric tension.

[0079] S680, Move the origin of the preset coordinate system to the initial seam starting point.

[0080] S690. Perform the zigzag seam operation according to the zigzag seam parameters.

[0081] S6100: Transfer the origin of the preset coordinate system to the overshoot coordinate.

[0082] S6110. Perform the second overshooting process according to the overshooting parameters.

[0083] Specifically, the second punching process can follow the first punching process to complete all the unfinished punching processes, thus completing the hole formation process in the pattern sewing process.

[0084] In some embodiments, the sewing sequence also includes a sewing process. Before performing pattern sewing, if the user selects a sewing process sequence of "sewing process" based on the desired recessed hole effect of the pattern sewing (e.g., creating a chrysanthemum-like recessed hole effect in the center of the fabric entirely through the arrangement, gathering, and tightening of the stitches), the pattern sewing method may only perform the sewing process. When performing the sewing process, the circular stitch process can be performed first, followed by the zigzag stitch process. Specifically, Figure 8 This is a flowchart illustrating another pattern sewing method provided in an embodiment of the present invention. (See attached diagram.) Figure 8As shown, the fancy sewing methods include: S710, Obtain the sewing parameters for the pattern.

[0085] S720, control the opening of the stitching function of the pattern sewing machine.

[0086] S730. After placing the center point of the pattern at the origin of the preset coordinate system, the origin of the preset coordinate system is sent to the preset origin coordinates by air according to the air delivery speed.

[0087] S740. Transfer the origin of the preset coordinate system from the preset origin coordinates to the first starting point of the arc seam.

[0088] S750, Perform the arc seam operation according to the arc seam parameters and the zigzag seam operation according to the zigzag seam parameters.

[0089] In some embodiments, continue to refer to Figures 4 to 8 The over-punching parameters also include the punching function switch, sewing sequence, and punching delay; the over-punching process is performed according to the over-punching parameters, including: Punching is performed at the over-punch coordinate.

[0090] After the punching is pressed down, a delay of the first preset time is performed.

[0091] The punching is lifted at the over-punch coordinate.

[0092] A second preset time delay is performed after the punching is lifted.

[0093] The first preset duration and the second preset duration can be equal, both of which are set by the punching delay in the punching parameters.
