[0002] With the development of technology, various embroidery machines have emerged to meet people's demands for different embroidery styles, enabling techniques such as ribbon embroidery, sequin embroidery, and zigzag embroidery.

[0062] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, not all embodiments. Based on the embodiments of this application, all other embodiments made by those skilled in the art under the guidance of these embodiments are within the scope of protection of this application.

[0063] The terms “first,” “second,” “third,” “fourth,” etc. (if present) in the specification, claims, and accompanying drawings of this application are used to distinguish similar objects and are not necessarily used to describe a particular order or sequence. It should be understood that such data can be interchanged where appropriate so that the embodiments of this application described herein can be implemented in orders other than those illustrated or described herein. Furthermore, the terms “comprising” and “having,” and any variations thereof, are intended to cover a non-exclusive inclusion; for example, a process, method, system, product, or apparatus that comprises a series of steps or units is not necessarily limited to those steps or units explicitly listed, but may include other steps or units not explicitly listed or inherent to such processes, methods, products, or apparatus.

[0064] With the development of technology, various embroidery machines have emerged to meet people's demands for different embroidery styles, enabling techniques such as ribbon embroidery, sequin embroidery, and zigzag embroidery. Sequin embroidery is a method of embroidery that uses needle and thread to fix gold sequins onto fabric, creating decorative patterns with gold sequins. Ribbon embroidery is a type of embroidery that involves stitching ribbons onto textiles, typically used in clothing and fabrics, and can create relatively three-dimensional patterns.

[0065] An embroidery product may require multiple techniques to meet the user's needs. For example, gold sequin embroidery may be added on top of ribbon embroidery to achieve a combination of ribbon and gold sequin embroidery.

[0066] In existing techniques, for ribbon and sequin embroidery, the embroidery machine typically has both ribbon embroidery and sequin embroidery equipment installed. The ribbon embroidery equipment first performs the ribbon embroidery, stitching the ribbon onto the base fabric, and then the sequin embroidery equipment performs the sequin embroidery, layering the sequins onto the ribbon. Because this requires two embroidery processes, it results in low embroidery efficiency.

[0067] To address the problems existing in the prior art, the inventors, during their research on the ribbon and sequin combination embroidery method, discovered that to improve embroidery efficiency, when performing each ribbon embroidery stitch, it is necessary to determine whether sequin embroidery is required. If sequin embroidery is needed, the sequin is placed on the ribbon and embroidered in one continuous motion, thus completing the ribbon and sequin combination embroidery in one go. Based on the above inventive concept, the ribbon and sequin combination embroidery scheme of this application was designed.

[0068] The following provides examples illustrating the application scenarios of the gold foil combination embroidery method provided in this application.

[0069] For example, in this application scenario, the user needs to use an embroidery machine to perform a combination embroidery with gold sequins. The embroidery machine includes multiple machine heads, each of which is equipped with a main spindle unit. The main spindle unit includes a main spindle transmission mechanism and a needle bar. The main spindle transmission mechanism is connected to the main spindle. When the main spindle rotates, the needle bar can be driven to move through the main spindle transmission mechanism to complete one stitch of embroidery.

[0070] The embroidery machine also includes a controller, an M-axis unit, a presser foot unit, a sequin unit, and an embroidery frame unit. Each main spindle unit corresponds to one M-axis unit, one presser foot unit, one sequin unit, and one embroidery frame unit.

[0071] When performing the combination embroidery with gold sequins, the controller acquires the pattern file and then sequentially stitches each stitch point in the sewing trajectory of the pattern file. After the stitch point preceding the stitch point is completed, the controller controls the embroidery frame in the embroidery frame unit to move the base fabric to the stitch position according to the stitch position of the stitch point.

[0072] Then, when the rotation angle of the main shaft reaches the preset angle, the M-axis transmission mechanism in the M-axis unit is controlled to rotate along the needle bar, driving the ribbon to rotate to the target angle, and then the presser foot in the presser foot unit is controlled to drop down, so that the presser foot presses down on the ribbon.

[0073] Then, it is determined whether the stitch data of the stitch point includes gold sequin data. If the stitch data of the stitch point includes gold sequin data, the gold sequin unit is controlled to place the gold sequin on the ribbon according to the gold sequin data. The main shaft rotates, and the needle bar is driven to move through the main shaft transmission mechanism to embroider the gold sequin and ribbon on the base fabric, realizing the combination embroidery of ribbon and gold sequin.

[0074] It should be noted that the above scenario is only an example of an application scenario provided by the embodiments of this application. The embodiments of this application do not limit the actual form of the various devices included in the scenario, nor do they limit the interaction method between devices. In the specific application of the solution, it can be set according to actual needs.

[0075] The technical solution of this application will now be described in detail through specific embodiments. It should be noted that the following specific embodiments can be combined with each other, and the same or similar concepts or processes may not be described again in some embodiments.

[0076] Figure 1aThis is a flowchart illustrating an embodiment of the gold sequin embroidery method provided in this application. This embodiment describes how the controller in the embroidery machine controls the embroidery frame to move the base fabric, which in turn controls the M-axis transmission mechanism to rotate the ribbon to the target angle. The presser foot presses down on the ribbon, and when gold sequins need to be embroidered, the sequins are placed on the ribbon for embroidery. The method in this embodiment can be implemented through software, hardware, or a combination of both. Figure 1a As shown, the specific steps of this gold sequin embroidery method include:

[0077] S101: Obtain the pattern file.

[0078] For example, Figure 1b The schematic diagram of the embroidery machine provided in this application is as follows: Figure 1b As shown, the embroidery machine includes a main spindle 11, a controller 12, multiple main spindle units (three main spindle units are shown in the figure, namely main spindle unit 13, main spindle unit 14, and main spindle unit 15), multiple M-axis units (three M-axis units are shown in the figure, namely M-axis unit 16, M-axis unit 17, and M-axis unit 18), presser foot units (three presser foot units are shown in the figure, namely presser foot unit 19, presser foot unit 20, and presser foot unit 21), multiple sequin units (three sequin units are shown in the figure, namely sequin unit 22, sequin unit 23, and sequin unit 24), and embroidery frame units (three embroidery frame units are shown in the figure, namely embroidery frame unit 25, embroidery frame unit 26, and embroidery frame unit 27).

[0079] The main spindle unit includes a main spindle drive mechanism and a needle bar. The main spindle drive mechanism in the main spindle unit is connected to the main spindle 11. When the main spindle 11 rotates, it can drive the needle bar to move through the main spindle drive mechanism to complete one stitch of embroidery.

[0080] Each spindle unit corresponds to one M-axis unit, one presser foot unit, one sequin unit, and one embroidery frame unit. In the diagram, spindle unit 13 corresponds to M-axis unit 16, presser foot unit 19, sequin unit 22, and embroidery frame unit 25; spindle unit 14 corresponds to M-axis unit 17, presser foot unit 20, sequin unit 23, and embroidery frame unit 26; and spindle unit 15 corresponds to M-axis unit 18, presser foot unit 21, sequin unit 24, and embroidery frame unit 27.

[0081] The M-axis unit, presser foot unit, sequin unit, and embroidery frame unit are connected to the controller 12; in the figure, M-axis unit 16-M-axis unit 18, presser foot unit 19-presser foot unit 21, sequin unit 22-sequin unit 24, and embroidery frame unit 25-embroidery frame unit 27 are connected to the controller 12.

[0082] It should be noted that, Figure 1bThis is merely an example of the structure of an embroidery machine, showing only three main spindle units and their corresponding M-axis units, presser foot units, sequin units, and embroidery frame units. The number of main spindle units in an embroidery machine can be 10, 100, 1000, etc. This application does not limit the number of main spindle units, M-axis units, presser foot units, sequin units, and embroidery frame units in an embroidery machine, and can be determined according to the actual situation.

[0083] In this step, when it is necessary to perform the combination embroidery with gold sequins, the embroidery machine is started. The motor in the embroidery machine is located at the set origin position. The controller in the machine obtains the pattern file, which includes the sewing trajectory, the stitch data of each stitch point in the sewing trajectory, and the stitch data including the stitch position.

[0084] S102: For each stitch point in the sewing trajectory, after the stitch point preceding the stitch point is completed, control the embroidery frame in the embroidery frame unit to move the base fabric to the stitch position according to the stitch position of the stitch point.

[0085] In this step, after the controller obtains the pattern file, it sequentially works on each stitch point in the sewing trajectory. After the stitch point preceding the stitch point is completed, the controller controls the embroidery frame in the embroidery frame unit to move the base fabric to the stitch point position according to the stitch position of the stitch point.

[0086] For example, Figure 1c A structural schematic diagram of the embroidery frame unit provided in this application is shown below. Figure 1c As shown, the embroidery frame unit includes an embroidery frame motor, an embroidery frame transmission mechanism, and an embroidery frame, which can hold the base fabric. The controller controls the rotation of the embroidery frame motor, which drives the embroidery frame to move through the embroidery frame transmission mechanism. The embroidery frame then moves the base fabric to the stitch position.

[0087] It should be noted that during the embroidery process, the main shaft will rotate continuously, driving the needle bar to embroider each stitch point. After a stitch point is completed, the main shaft rotates to drive the needle bar away from the base fabric.

[0088] S103: When the rotation angle of the main shaft in the embroidery machine reaches the preset angle, the M-axis transmission mechanism in the M-axis unit is controlled to rotate along the needle bar, driving the ribbon to rotate to the target angle.

[0089] In this step, after the controller moves the embroidery frame and the base fabric to the stitch position, the controller monitors the rotation angle of the main shaft in the embroidery machine. When the controller detects that the rotation angle of the main shaft in the embroidery machine has reached the preset angle, it means that the needle bar has left the base fabric and is a certain distance away from the base fabric. The controller then controls the M-axis transmission mechanism in the M-axis unit to rotate along the needle bar. The M-axis transmission mechanism can drive the ribbon to rotate along the needle bar, so that the ribbon rotates to the target angle.

[0090] The ribbon position corresponding to the target angle is aligned with the stitch position of the stitch point and the stitch position of the previous stitch point, so that the ribbon is directly in front of the sewing path.

[0091] For example, Figure 1d This application provides a schematic diagram showing the positions of the ribbons corresponding to the trajectory points and target angles. Figure 1d As shown in the diagram, there are three black stitch points: stitch point A, stitch point B, and stitch point C. The stitch point to be sewn is stitch point B, and stitch point A is the previous stitch point of stitch point B. The white point D in the diagram represents the ribbon position corresponding to the target angle. The ribbon position D corresponding to the target angle is on a straight line with stitch points B and A, ensuring that the ribbon is directly in front of the sewing path.

[0092] It should be noted that the preset angle can be 10 degrees, 30 degrees, 60 degrees, etc. This application embodiment does not limit the preset angle, and it can be set according to the actual situation.

[0093] For example, Figure 1e The structural schematic diagram of the M-axis unit provided in this application is as follows: Figure 1e As shown, the M-axis unit includes an M-axis motor and an M-axis transmission mechanism. The controller controls the rotation of the M-axis motor, which drives the M-axis transmission mechanism to rotate along the needle bar. The M-axis transmission mechanism can drive the ribbon to rotate along the needle bar, so that the ribbon rotates to the target angle.

[0094] It should be noted that the controller can directly determine the target angle based on the stitch position of the current stitch point to be sewn and the stitch position of the previous stitch point; it can also first determine the moving direction of the embroidery frame, then determine the opposite direction of the moving direction, and then determine the target angle corresponding to the opposite direction.

[0095] S104: Control the presser foot in the presser foot unit to lower so that the presser foot presses down on the ribbon.

[0096] In this step, the controller controls the M-axis transmission mechanism to rotate along the needle bar, causing the ribbon to rotate to the target angle, and then controls the presser foot in the presser foot unit to lower, so that the presser foot presses down on the ribbon.

[0097] For example, Figure 1f A schematic diagram of the presser foot unit provided in this application is shown below. Figure 1f As shown, the presser foot unit includes a presser foot motor and a presser foot. The controller controls the presser foot motor to rotate, which in turn drives the presser foot to lower.

[0098] S105: If the stitch data of the stitch point includes gold foil data, the gold foil unit is controlled to place the gold foil on the ribbon according to the gold foil data; the main shaft rotates, and the needle bar is driven to move through the main shaft transmission mechanism to embroider the gold foil and ribbon on the base fabric.

[0099] In this step, after the controller lowers the presser foot, in order to determine whether the current stitch point needs to be embroidered with sequins, it is necessary to determine whether the stitch data of the stitch point includes sequin data.

[0100] If the stitch data of the stitch point includes gold flake data, the gold flake unit is controlled to place the gold flake on the ribbon according to the gold flake data; the main shaft rotates, and the needle bar is driven to move through the main shaft transmission mechanism to embroider the gold flake and ribbon on the base fabric, thus completing the embroidery of the current stitch point.

[0101] For example, Figure 1g A schematic diagram of the structure of the gold sheet unit provided in this application is shown below. Figure 1g As shown, the gold sheet unit includes a gold sheet motor and a gold sheet transmission mechanism. The controller controls the gold sheet motor to rotate, which drives the gold sheet transmission mechanism to place the gold sheet on the ribbon.

[0102] It should be noted that this solution can achieve single-piece embroidery as well as multi-piece embroidery.

[0103] It should be noted that after a stitch is completed, the controller controls the presser foot to be lowered and raised.

[0104] It should be noted that when the current stitch point is the first stitch point in the sewing trajectory, after the controller obtains the pattern file, it directly controls the embroidery frame to move the base fabric to the stitch position of that stitch point. Therefore, the target angle can be any angle.

[0105] It should be noted that if the stitch data of the stitch point does not include the sequin data after the controller controls the presser foot to be lowered, it means that the stitch point does not need to be embroidered with sequins. The controller does not need to control the operation of the sequin unit. The spindle rotates and drives the needle bar to move through the spindle transmission mechanism to embroider the ribbon onto the base fabric.

[0106] The method for combining ribbon and sequin embroidery provided in this embodiment, after obtaining the pattern file through the controller, sequentially moves the embroidery frame in the embroidery frame unit to the stitch position for each stitch point. Then, it controls the M-axis transmission mechanism in the M-axis unit to rotate along the needle bar, rotating the ribbon to the target angle. Next, it controls the presser foot in the presser foot unit to lower, pressing the ribbon down. If the stitch data of the stitch point includes sequin data, the sequin unit places the sequin on the ribbon according to the sequin data. The main shaft rotates, and the main shaft transmission mechanism in the main shaft unit drives the needle bar to move, embroidering the sequin and ribbon onto the base fabric. This solution, through the main shaft unit, M-axis unit, presser foot unit, sequin unit, and embroidery frame unit, achieves the completion of ribbon and sequin embroidery in one operation, effectively improving embroidery efficiency. In addition, when there are repeated stitch points in the sewing path, the ribbons will overlap. In the existing technology, the embroidery is done twice, so that the gold sequins at the stitch point are all on the ribbon. It is not possible to have embroidered gold sequins between the overlapping ribbons. This solution can achieve the effect of having embroidered gold sequins between the overlapping ribbons, thus improving the embroidery effect.

[0107] Figure 2a This is a flowchart illustrating a second embodiment of the gold sequin embroidery method provided in this application. Based on the above embodiments, this application further includes a switching mechanism for the main shaft unit, illustrating how the connection position between the main shaft transmission mechanism and the needle bar is switched based on the switching result. For example... Figure 2a As shown, the specific steps of this gold sequin embroidery method include:

[0108] S201: Based on the preset correspondence between angles and connecting mechanisms, determine the target connecting mechanism corresponding to the target angle from among multiple connecting mechanisms.

[0109] When there is only one connection point between the main shaft drive mechanism and the needle bar, the ribbon may get tangled on the main shaft unit when the M-axis drive mechanism rotates along the needle bar. To avoid this, more connection points can be added.

[0110] For example, Figure 2b A schematic diagram of the spindle unit provided in this application is shown below. Figure 2b As shown, the spindle unit includes a switching mechanism, a spindle drive mechanism, and a needle bar. The switching mechanism is connected to the controller.

[0111] The needle bar has multiple connection points on its periphery, and the main shaft transmission mechanism includes multiple connection mechanisms that correspond one-to-one with the connection points on the needle bar.

[0112] For example, Figure 2c This is a schematic diagram illustrating the connection between the connecting mechanism and the needle bar provided in this application, as shown below. Figure 2cAs shown, the needle bar 31 has multiple connection points around its periphery (two connection points are shown in the figure, namely connection point 32 and connection point 33). The main shaft transmission mechanism includes multiple connection mechanisms that correspond one-to-one with the connection points on the needle bar (two connection mechanisms are shown in the figure, namely connection mechanism 34 and connection mechanism 35). The switching mechanism can switch the connection mechanism to the corresponding connection point.

[0113] It should be noted that the number of connection points and switching mechanisms can be 2, 4, 8, etc. This application embodiment does not limit the number of connection points and switching mechanisms, and can be determined according to the actual situation.

[0114] In this step, when the controller detects that the rotation angle of the spindle has reached the preset angle, the target angle to which the M-axis transmission mechanism drives the ribbon to rotate can be determined. Then, based on the preset angle and the correspondence between the connecting mechanisms, the target connecting mechanism corresponding to the target angle can be determined from multiple connecting mechanisms.

[0115] S202: The control switching mechanism connects the target connection mechanism with the target connection point corresponding to the target connection mechanism.

[0116] In this step, after the controller identifies the target connection mechanism, it controls the switching mechanism to connect the target connection mechanism with the target connection point corresponding to the target connection mechanism, so that the angle corresponding to the target connection point is different from the target angle, which can prevent the ribbon from getting tangled on the spindle unit.

[0117] It should be noted that the direction of the angle corresponding to the target connection point can be opposite to the direction of the target angle.

[0118] The method for combining gold sequins with ribbon embroidery provided in this embodiment uses multiple connection points set around the needle bar and a connection mechanism that corresponds one-to-one with the connection points on the needle bar. The switching mechanism completes the switching of the connection position between the main shaft drive mechanism and the needle bar, which can prevent the ribbon from getting tangled on the main shaft unit.

[0119] Figure 3a This is a flowchart illustrating a third embodiment of the gold sequin embroidery method provided in this application. Based on the above embodiments, this application describes how various gold sequin embroidery scenarios can be achieved when the gold sequin transmission mechanism includes a gold sequin changing screw and a shift fork mechanism. For example... Figure 3a As shown, the specific steps of this gold sequin embroidery method include:

[0120] S301: Controls the gold sheet motor to rotate, which drives the gold sheet changing screw to move, so that the gold sheet on the gold sheet changing screw moves to the preset position.

[0121] This solution can achieve not only single-sequin embroidery but also multi-sequin embroidery. For example, Figure 3bThe schematic diagram of the gold sheet transmission mechanism provided in this application is as follows: Figure 3b As shown, the gold sheet transmission mechanism includes a gold sheet changing screw 41 and a shift fork mechanism 42. Different types of gold sheets can be placed on the gold sheet changing screw 41. The gold sheet changing screw 41 is used to transmit different types of gold sheets to the position of the shift fork mechanism 42; the shift fork mechanism 42 is used to shift the gold sheets onto the base fabric.

[0122] It should be noted that different types can be different colors or different sizes.

[0123] In this step, if the stitch data of the stitch point includes gold sheet data, and the gold sheet data includes the gold sheet type and the number of gold sheets, the controller can control the gold sheet motor to rotate according to the gold sheet type, thereby driving the gold sheet changing screw to move, so that the gold sheet of that type on the gold sheet changing screw moves to a preset position, which is the position of the shift fork mechanism.

[0124] S302: Controls the gold sheet motor to rotate, driving the shift fork mechanism to place the gold sheet from a preset position onto the ribbon.

[0125] In this step, after the controller moves the gold sheet replacement screw, it controls the gold sheet motor to rotate according to the number of gold sheets, which drives the shift fork mechanism to place the number of gold sheets from the preset position onto the ribbon.

[0126] The method for combining gold sequins in this embodiment can achieve the embroidery of multiple gold sequins by setting a gold sequin changing screw and a fork mechanism.
