[0001] This application relates to the field of mechanical technology, and in particular to a method for controlling the thread end of the starting stitch of an embroidery machine, an electronic device, and a storage medium. Background Technology

[0002] The term "starting thread tail" in embroidery refers to the thread tail that is sewn to the reverse side of the fabric after the embroidery machine has finished cutting the thread. If the thread tail is too long after cutting, it will leave a residual thread tail on the reverse side of the embroidery after the sewing is completed. Furthermore, an excessively long thread tail will ruin the appearance of the embroidery.

[0003] In existing methods for handling the thread ends at the start of embroidery, the thread end handling on the reverse side of the fabric is mainly achieved through a thread clamping device.

[0004] The existing processing method for the face thread clamping device to process the face thread ends results in excessively long thread ends on the reverse side of the fabric, which increases the length of the face thread ends and damages the aesthetics of the embroidery.

[0056] The accompanying drawings illustrate specific embodiments of this application, which will be described in more detail below. These drawings and descriptions are not intended to limit the scope of the concept in any way, but rather to illustrate the concept of this application to those skilled in the art through reference to particular embodiments. Detailed Implementation

[0057] Exemplary embodiments will now be described in detail, examples of which are illustrated in the accompanying drawings. When the following description relates to the drawings, unless otherwise indicated, the same numerals in different drawings represent the same or similar elements. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with this application. Rather, they are merely examples of apparatuses and methods consistent with some aspects of this application as detailed in the appended claims, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of this invention without inventive effort are within the scope of protection of this invention.

[0058] The terms “first,” “second,” “third,” “fourth,” etc. (if present) in the specification, claims, and accompanying drawings of this invention 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 embodiments of the invention described herein can be implemented, for example, 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, system, product, or apparatus that comprises a series of steps or units is not necessarily limited to those explicitly listed, but may include other steps or units not explicitly listed or inherent to such processes, products, or apparatus.

[0059] In this application, the terms "exemplary" or "for example" are used to indicate examples, illustrations, or descriptions. Any embodiment or design described as "exemplary" or "for example" in this application should not be construed as being more preferred or advantageous than other embodiments or designs. Specifically, the use of terms such as "exemplary" or "for example" is intended to present the relevant concepts in a specific manner.

[0060] It should be noted that the user information (including but not limited to user device information, user personal information, etc.) and data (including but not limited to data used for analysis, data stored, data displayed, etc.) involved in this application are all information and data authorized by the user or fully authorized by all parties. Furthermore, the collection, use and processing of the relevant data must comply with the relevant laws, regulations and standards of the relevant countries and regions, and corresponding operation portals are provided for users to choose to authorize or refuse.

[0061] In embroidery machines, the top thread, also called the upper thread, refers to the thread that passes through the head of the embroidery machine. After the embroidery machine sews, the main body of the top thread is on the right side of the fabric, and the end of the top thread is on the wrong side of the fabric. The bottom thread, also called the lower thread, refers to the thread inside the embroidery machine's rotary hook. The embroidery machine's rotary hook is equipped with a shuttle case, and the bobbin inside the shuttle case is wound with the bottom thread. After the embroidery machine sews, the bottom thread is on the wrong side of the fabric, and the end of the bottom thread is on the wrong side of the fabric. The rotary hook includes horizontal rotary hooks and vertical rotary hooks, which are mainly used in conjunction with the needle and thread to form lockstitch. The shuttle case is the component that holds the shuttle thread and is fixed in the rotary hook system of the embroidery machine.

[0062] Thread trimming on an embroidery machine refers to the process of cutting the bottom and top threads after a portion of the pattern or a particular color of thread has been completed during the machine's operation. This allows for subsequent embroidery work. After trimming, the top thread ends are held on the machine head, while the bottom thread ends are held near the rotary hook. When starting embroidery after trimming, the needle and rotary hook work together to re-tie the bottom and top thread ends, enabling normal sewing. In embroidery machine operations, the first stitch usually refers to the cycle of the needle tip first entering and exiting the fabric.

[0063] The loose thread at the start of an embroidery machine refers to the excess thread that appears on the surface of the embroidery machine when the embroidery operation begins. It is usually caused by reasons such as not cutting the thread before changing the thread or starting the machine, or the thread thickness not matching the needle eye. These loose threads may cause problems such as thread breakage and skipped stitches during the embroidery process.

[0064] For the thread ends at the start of an embroidery machine, methods such as mechanical adjustment, manual processing, and automated processing are commonly used to handle them. The appropriate method is selected based on factors such as the requirements of the embroidery work and the performance of the embroidery machine.

[0065] As long as the machinery allows, embroidery machines are equipped with a thread clamping device. In the common process of handling the thread ends at the start of an embroidery stitch, the thread clamping device is mainly used to control the movement of the clamp to ensure that the thread ends do not come loose during the start of the stitch.

[0066] Controlling the movement of the face clamp in the face clamping device to cut off the starting thread of the embroidery machine includes: when starting embroidery after the thread is cut, the face clamp performs an opening and closing action once for each stitch of the embroidery.

[0067] Using a thread clamping device to control the movement of the thread clamp to ensure that the thread does not come loose when starting a stitch cannot improve the problem of excessively long thread ends on the reverse side of the fabric. Instead, it will increase the length of the thread ends and affect the aesthetics of the embroidery.

[0068] To address the aforementioned issues, this application provides a method for controlling the thread end length at the start of an embroidery machine. This method acquires the rotation angle of the embroidery machine's main shaft in real time and switches the operating state of the thread clamping device based on this rotation angle. Because the clamping device operates three times within the first stitch at a preset main shaft angle, it significantly improves the thread end length issue at the start of the stitch on the reverse side of the fabric, greatly enhancing the aesthetic appeal of the embroidery.

[0069] Figure 1 The flowchart of the embroidery machine starting thread control method provided in this embodiment Figure 1 .like Figure 1 As shown in the figure, this embodiment provides a method for controlling the thread end of the starting stitch on an embroidery machine, including:

[0070] S101. Obtain the rotation angle of the embroidery machine spindle in real time.

[0071] Embroidery machines are automated devices used for embroidering fabrics. They utilize a control system to convert designed patterns into machine-readable instructions, driving various mechanical components such as needle bars, rotary hooks, and thread take-up levers to perform embroidery operations. Embroidery machines are widely used in garment embroidery and processing, decorations, home furnishings, and fabric processing.

[0072] The main spindle of an embroidery machine typically consists of a spindle motor, transmission mechanism, spindle body, and related sensors and controllers, controlling various movements of the embroidery machine during the embroidery process. The rotation angle of the embroidery machine spindle refers to the angle through which the spindle rotates relative to a certain initial position during the embroidery process. This angle is usually measured and represented by a code disk or sensor connected to the spindle, used for precise control of the embroidery machine's operation.

[0073] During the operation of the embroidery machine, the main shaft rotates 360 degrees for each revolution and embroiders one stitch. When the embroidery machine is stopped, if the main shaft stops at the 100-degree mark, that is, with 100 degrees as the reference point, each component of the embroidery machine completes its own action at different angles from 0 to 360 degrees during the rotation of the main shaft, so that the embroidery machine system can operate normally.

[0074] In this step, the rotation angle of the embroidery machine spindle is obtained in real time, for example, through sensors, motor feedback, transformers, etc., and the obtained rotation angle of the embroidery machine spindle is transmitted to the control system.

[0075] S102. When the embroidery machine enters the first stitch of the embroidery program after the thread cutting, the operating state of the face thread clamping device is switched based on the rotation angle to control the passing state of the embroidery machine face thread relative to the corresponding thread hole.

[0076] The thread clamping device is in a suction state before entering the thread cutting and embroidery process.

[0077] The thread-cutting and embroidery-starting procedures of an embroidery machine are two operational steps in the automated embroidery process, used to ensure the continuity and quality of the embroidery.

[0078] In this step, the embroidery machine's thread-cutting program includes locking the needle, cutting the thread, and handling the thread ends; the embroidery-starting program includes debugging, determining the starting point, and the initiation and continuous process of embroidery.

[0079] The thread clamping device is a key component in embroidery machines. It uses a series of clamping parts to fix the thread on the fabric and controls the position of the pressure block through an elastic clamping structure to clamp the thread. Furthermore, it manages and controls the tension and position of the thread during the embroidery process to achieve high-quality embroidery results.

[0080] The thread clamping device has two states: open and closed. In the open state, the thread can pass through the thread hole, and in the closed state, the thread is clamped.

[0081] Understandably, switching the operating state of the thread clamping device based on the rotation angle means controlling the operating state of the thread clamping device by acquiring the rotation angle of the embroidery machine spindle in real time; different operating states of the thread clamping device correspond to different passing states of the thread holes.

[0082] In one possible implementation, the switching of the operating state of the face wire clamping device based on the rotation angle can be achieved by the following method:

[0083] Select a suitable sensor to acquire the spindle rotation angle in real time. This sensor can accurately record the spindle rotation angle and transmit the recorded spindle rotation angle to the corresponding control system.

[0084] In this step, the sensor type can be selected from photoelectric sensors, Hall effect sensors, etc., and there are no restrictions.

[0085] Connect the sensor, control system, and thread clamping device to ensure that the control system can read the rotation angle of the spindle in real time. Based on the read rotation angle, the control system causes the thread clamping device to trigger the corresponding state at a specific angle.

[0086] In this step, the design of the control system includes data reading, event triggering, and command transmission. Data reading involves real-time reading of data uploaded by sensors; event triggering generates control commands to trigger corresponding events at specific spindle rotation angles; and command transmission transmits the control commands generated by the control system to the wire clamping device, controlling the device to change its operating state.

[0087] The embroidery machine starting thread end control method provided in this embodiment acquires the rotation angle of the embroidery machine spindle in real time. When the embroidery machine enters the first stitch of the starting embroidery program after thread trimming, the operating state of the thread clamping device is switched based on the rotation angle to control the passage state of the embroidery machine thread relative to the corresponding thread guide hole. This method effectively reduces the length of the thread end on the reverse side of the fabric at the starting position, improving the aesthetics of the embroidered product.

[0088] Figure 2 The flowchart of the embroidery machine starting thread control method provided in this embodiment Figure 2 In this embodiment, the operating states of the face thread clamping device include: an open state and a closed state. This embodiment... Figure 1 Based on the embodiments, the operation state switching process of the face wire clamping device will be explained. For example... Figure 2 As shown, the method includes:

[0089] S201. After the embroidery machine is powered on, the thread clamping device is reset.

[0090] The process of resetting the thread clamping device involves restoring the embroidery machine to its state when it was last powered off, ensuring that the thread clamping device is in the correct initial state, i.e., restored to a known initial state, so that stable embroidery operations can be performed subsequently.

[0091] In this step, the reset process of the face wire clamping device can be accomplished, for example, by power-on initialization, resetting the face wire clamping device reset status information, executing the reset process, and confirming the status after the reset process.

[0092] In one possible implementation, resetting the face wire clamping device can be achieved by the following method:

[0093] The face thread clamping device is controlled to enter the open state, and after a preset time, the face thread clamping device is controlled to switch from the open state to the suction state;

[0094] When the embroidery machine starts embroidering or needs to adjust the thread, the control system issues a command to drive the drive rod to move, causing the pressure block to separate from the thread clamping seat, thereby opening the thread clamping device and putting it into the open state. After the thread clamping device is opened, the preset time is usually determined according to the needs of the embroidery process and the performance of the embroidery machine to ensure that the thread can be clamped in time when needed. After the preset time has elapsed, the control system issues a command to drive the drive rod to move in the opposite direction, causing the pressure block to tightly engage with the thread clamping seat, thereby causing the thread clamping device to switch to the suction state.

[0095] Determine the status information of the thread clamping device when the embroidery machine was previously powered off;

[0096] The status information of the embroidery machine when it was last powered off refers to the working status and related settings saved by the thread clamping device when the power was last turned off.

[0097] In this step, the status information of the thread clamping device mainly includes, but is not limited to, the clamping status and position information of the thread clamping device.

[0098] In one possible implementation, determining the state information of the thread clamping device at the time of the previous power-off of the embroidery machine can be achieved by the following method:

[0099] The control system monitors the changes in the state of the thread clamping device during the operation of the embroidery machine.

[0100] When the embroidery machine is powered off, the control system saves the current status information of the thread clamping device to the memory;

[0101] By comparing the current state with the stored state information, the embroidery machine can determine the state of the thread clamping device when it was last powered off.

[0102] When the embroidery machine head starts, the thread clamping device is reset based on the status information.

[0103] In one possible implementation, resetting the face wire clamping device based on the state information can be achieved by the following method:

[0104] The control system reads the status information of the thread clamping device when the embroidery machine was last powered off, and sends a drive command to drive the pressure block, drive rod and other components of the thread clamping device to perform the reset process.

[0105] During the reset process, the control system records the information of the face wire clamping device in real time, and confirms the status after the reset is completed.

[0106] S202. Obtain the rotation angle of the embroidery machine spindle in real time.

[0107] Step S202 is similar to step S101 above, and will not be described again here.

[0108] S203. When the embroidery machine enters the first stitch of the embroidery program after the thread is cut, determine whether the rotation angle has reached the first preset angle; if yes, proceed to step S204; if no, return to step S203.

[0109] Specifically, when the embroidery machine enters the thread-cutting and starting-embroidery program for the first stitch, the main shaft of the embroidery machine is at a reference angle, which is a preset angle; the reference angle is less than the rotation angle; and the first preset angle is greater than the reference angle.

[0110] In this step, the first preset angle can be set to, for example, an angle between 110° and 130°.

[0111] In one possible implementation, the initial reference angle of the main axis in the first stitch of embroidery can be... Figure 3The 100° setting in the middle, the first preset angle can be Figure 3 The setting is 120°.

[0112] S204. Control the face thread clamping device to switch from the suction state to the open state.

[0113] The control system controls the face wire clamping device to switch from the closed state to the open state, which is achieved by transmitting corresponding control commands through the control system.

[0114] S205. Determine whether the rotation angle has reached the second preset angle. If yes, proceed to step S206; otherwise, return to step S204.

[0115] The second preset angle is greater than the first preset angle.

[0116] In this step, the second preset angle can be set to, for example, an angle between 180° and 200°.

[0117] In one possible implementation, the second preset angle can be... Figure 3 The setting is 190°.

[0118] S206. Control the face thread clamping device to switch back from the open state to the closed state.

[0119] Step S206 is similar to step S204 above, and will not be described again here.

[0120] S207. Determine whether the rotation angle has reached the third preset angle; if yes, proceed to step S208; if no, return to step S207.

[0121] The third preset angle is greater than the second preset angle, and the first preset angle, the second preset angle, and the third preset angle are in the same rotation cycle of the main shaft.

[0122] In this step, the third preset angle can be set to, for example, an angle between 290° and 310°.

[0123] In one possible implementation, the third preset angle can be... Figure 3 The setting is 300°.

[0124] S208. Control the face thread clamping device to switch from the suction state to the open state.

[0125] Step S208 is similar to step S204 above, and will not be described again here.

[0126] The embroidery machine starting thread end control method provided in this embodiment involves resetting the thread clamping device after the embroidery machine is powered on; acquiring the rotation angle of the embroidery machine spindle in real time; determining whether the rotation angle has reached a first preset angle; if the rotation angle has reached the first preset angle, controlling the thread clamping device to switch from a closed state to an open state; determining whether the rotation angle has reached a second preset angle; if the rotation angle has reached the second preset angle, controlling the thread clamping device to switch back from the open state to the closed state; determining whether the rotation angle has reached a third preset angle; if the rotation angle has reached the third preset angle, controlling the thread clamping device to switch back from the closed state to the open state. This method significantly improves the thread end length problem at the starting position on the reverse side of the fabric without increasing the problem of thread detachment during starting, and does not increase the physical cost of the embroidery machine.

[0127] Figure 4 This application provides a device for controlling the thread end of the starting stitch on an embroidery machine. For example... Figure 4 As shown in the embodiment of this application, the embroidery machine starting thread control device 400 includes:

[0128] The acquisition module 401 is used to acquire the rotation angle of the main shaft of the embroidery machine in real time;

[0129] The processing module 402 is used to switch the operating state of the face thread clamping device based on the rotation angle when the embroidery machine enters the first stitch of the embroidery program after the thread cutting. This is to control the passing state of the face thread of the embroidery machine relative to the corresponding thread hole, wherein the face thread clamping device is in a suction state before entering the thread cutting and embroidery program.

[0130] In one possible implementation, the processing module 402 is further configured to reset the thread clamping device after the embroidery machine is powered on.

[0131] In one possible implementation, the processing module 402 is further configured to control the thread clamping device to enter the open state, and after a preset time, control the thread clamping device to switch from the open state to the closed state; determine the state information of the thread clamping device when the embroidery machine was previously powered off; and, based on the state information, perform a reset process on the thread clamping device when the embroidery machine head is started.

[0132] This embodiment provides a thread end control device for the starting stitch surface of an embroidery machine, which can execute the thread end control method for the starting stitch surface of an embroidery machine provided in the above method embodiment. Its implementation principle and technical effect are similar, and will not be described in detail here.

[0134] The judgment module 501 is used to determine whether the rotation angle has reached the first preset angle;

[0135] Processing module 502 is used to control the face wire clamping device to switch from the suction state to the open state when the rotation angle reaches the first preset angle;

[0136] The judgment module 501 is also used to determine whether the rotation angle has reached the second preset angle;

[0137] The processing module 502 is also used to control the face wire clamping device to switch back from the open state to the suction state when the rotation angle reaches the second preset angle.

[0138] The judgment module 501 is also used to determine whether the rotation angle has reached the third preset angle;
