[0042] 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

[0043] 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 numbers in different drawings denote 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.

[0044] The application background of this application is explained as follows:

[0045] Metal spring wire embroidery, also known as metal spring embroidery, metal embroidery stamp, spring metal embroidery, metal hand embroidery stamp, or hand embroidery stamp, mainly uses copper (or synthetic metals or composite materials for cost reasons) spring-shaped metal wires as raw materials. By embedding the metal wires into the surface of the fabric, a three-dimensional pattern with a metallic luster is formed, and it is widely used in the field of clothing decoration.

[0046] Currently, metal spring wire embroidery is entirely handmade. Embroiderers must manually judge and cut the metal wire to the required length by eye, then use specialized tools to feed the wire stitch by stitch under the embroidery needle to complete the embroidery. This process demands extremely high levels of skill, hand coordination, and understanding of the properties of the metal wire. Due to the inherent flexibility and deformability of the metal wire, the production efficiency of hand embroidery is limited by the speed of a single operator, making it difficult to meet the demands of large-scale production.

[0047] In summary, traditional hand embroidery has significant limitations: on the one hand, the special material of metallic wire demands extremely high skill and strength from the embroiderer, resulting in a high skill threshold and a long learning cycle; on the other hand, manual operation relies on individual experience, making it difficult to guarantee the consistency of patterns and the stability of mass production. Therefore, providing a control method for an automated metallic spring wire embroidery device to overcome the limitations of traditional embroidery techniques in terms of production efficiency, cost, and sample consistency, and to achieve mechanized and standardized production of metallic wire embroidery, is an urgent technical problem to be solved.

[0048] Based on the aforementioned technical problems, the inventors, in the process of researching automated control methods for metal spring wire embroidery devices, discovered that by leveraging the physical properties (rigidity and elasticity) of metal spring wire and the motion law of the embroidery machine's main shaft, and through the linkage control of the feeding section, wire cutting section, clamping section, and lifting mechanism, precise and coordinated control of the feeding amount, wire cutting length, and wire feeding sequence in the metal spring wire embroidery process can be achieved. This allows it to replace traditional hand embroidery, solving the technical bottlenecks in efficiency, precision, and stability inherent in hand embroidery. Based on this, this application provides a control method, device, system, and medium for a metal spring wire embroidery device.

[0049] It should be noted that the control method of the metal spring wire embroidery device provided in this application can be used to control the metal spring wire device to complete the feeding, cutting, and feeding of the wire to the needle of the embroidery machine, and to cut different lengths of metal spring wire according to the pattern, so as to cooperate with the embroidery machine to complete the machine embroidery function of the metal spring wire embroidery process, thereby improving production efficiency and the consistency of the pattern.

[0050] The technical solution of this application and how it solves the above-mentioned technical problems will be described in detail below with specific embodiments. These specific embodiments can be combined with each other, and the same or similar concepts or processes may not be described again in some embodiments. The embodiments of this application will be described below with reference to the accompanying drawings.

[0051] Figure 1 A flowchart illustrating the control method for a metal spring wire embroidery device provided in this application. Figure One ,like Figure 1 As shown, the method includes:

[0052] S101: Receives instructions sent by the embroidery machine, including: indication information on whether metal spring wire is needed and the required length of metal spring wire.

[0053] In this step, metal spring wire is used as an auxiliary material. Building upon the regular embroidery thread operation (flat embroidery) on the embroidery machine, it works in conjunction with the embroidery thread to precisely deliver the metal spring wire to the needle-operated area. Ultimately, the metal spring wire is firmly embroidered onto the fabric surface using the sewing trajectory of the embroidery thread. This stable transfer from auxiliary material supply to the needle-operated area is achieved without affecting the needle's piercing action or the smoothness of the embroidery thread's movement. The instruction refers to the core control command that facilitates signal exchange between the embroidery machine and the main control module that controls the metal spring wire embroidery device. It specifies the key parameters for using the metal spring wire during the embroidery operation, including whether metal spring wire is needed and the required length of metal spring wire.

[0054] Specifically, the indication information used to indicate whether metal spring wire is needed is a logical instruction parameter, which can be a binary signal or a flag bit status, etc., used to accurately determine whether metal spring wire is needed for the needle-feeding operation in the embroidery process; the length of the metal spring wire is a quantitative instruction parameter preset stitch by stitch in the pattern design stage, usually in millimeters, centimeters, etc., used to control the length of metal spring wire required for each stitch, that is, the specific length of metal spring wire in a single wire-taking operation.

[0055] S102: When the instruction indicates that a metal spring wire is needed, cut a metal spring wire segment of the corresponding length according to the instruction.

[0056] Understandably, metal spring wire segments refer to metal spring wires that are precisely cut by the wire-cutting part of the control device of the metal spring wire embroidery device according to the length parameters in the instructions. Their length is precisely matched with the needs of the current embroidery stitch and is the core material form to ensure subsequent embroidery in conjunction with conventional embroidery threads.

[0057] Specifically, the wire-cutting part of the control device of the metal spring wire embroidery device consists of three mechanisms: a pressure roller, a guide tube, and a cutter. For example, the length is converted into a drive signal for the pressure roller. The roller surface forms a stable frictional force with the surface of the metal spring wire. Under appropriate clamping force, the metal spring wire is smoothly output from the storage reel according to the rotation angle and number of turns corresponding to the length. Simultaneously, a length detection component (such as a photoelectric encoder) can provide real-time feedback on the output progress, ensuring that the wire length error is controlled within the allowable range. The output metal spring wire is directionally conveyed to the clamping mechanism under the guidance and constraint of the guide tube. The inner wall of the guide tube is smoothed to reduce the frictional resistance of the metal spring wire, preventing bending, tangling, or surface damage during conveying. The clamping mechanism ensures that the metal spring wire can be temporarily fixed, providing a stable reference for subsequent cutting operations. When the output length of the metal spring wire reaches the length indicated in the command, the cutter precisely cuts the metal spring wire at the cutting position corresponding to the length between the guide tube and the clamping mechanism, obtaining a metal spring wire segment.

[0058] The entire cutting process is achieved through a closed-loop synergy formed by the precise wire feeding of the pressure roller, the directional guidance of the guide tube, and the instantaneous cutting of the cutter, which ensures the length accuracy of the metal spring wire segment and realizes the automation, high precision, and high stability of metal spring wire auxiliary material cutting.

[0059] S103: The metal spring wire segment is fed to the needle position of the embroidery machine to complete the embroidery.

[0060] In this step, the needle insertion position refers to the core working point where the embroidery machine performs the piercing action.

[0061] Specifically, the clamping mechanism, through its built-in drive component (shift fork motor), transports the metal spring wire segment to the needle insertion position of the embroidery machine at a specific angle on the main shaft, thus completing the embroidery. During the transport process, the actuation speed of the metal spring wire segment is synchronized with the rotation speed of the main shaft in real time, ensuring that the arrival time of the metal spring wire segment at the needle insertion position precisely matches the timing of the needle insertion. For example, when the main shaft of the embroidery machine rotates to the needle insertion trigger angle, the metal spring wire segment is just in place and maintains a stable posture. At this moment, the clamping mechanism releases the metal spring wire segment, achieving seamless coordination between the transport of the metal spring wire segment and the core operation of the embroidery machine. This provides crucial support for the subsequent secure embroidery of the metal spring wire segment onto the fabric surface.

[0062] The control method for the metal spring wire embroidery device provided in this application embodiment receives instructions from the embroidery machine to obtain indications of whether metal spring wire is needed and the required length of metal spring wire. When metal spring wire is needed, it precisely cuts a metal spring wire segment of the corresponding length based on the instruction. The cutting components, such as pressure rollers, guides, and cutters, work together to achieve automated wire feeding, guiding, and cutting. Finally, a clamping mechanism transports the metal spring wire segment to the needle insertion position of the embroidery machine, ensuring real-time linkage and precise timing with the needle piercing action to complete the embroidery. Through this method, a stable supply and delivery of metal spring wire as an auxiliary material is achieved. Without interfering with needle piercing and thread movement, precise length control and synchronous delivery allow the metal spring wire to work in conjunction with conventional embroidery thread, firmly attaching it to the fabric surface, thereby improving the automation, precision, and reliability of the embroidery process.

[0063] Figure 2 A flowchart illustrating the control method for a metal spring wire embroidery device provided in this application. Figure Two ,like Figure 2 As shown, in Figure 1 Based on the embodiments, the instructions also include an identifier for a needle requiring a metal spring wire, and the method further includes:

[0064] S201: Obtain the spindle angle and spindle speed of the embroidery machine.

[0065] In this step, the embroidery machine spindle refers to the core power shaft that drives the embroidery needle to perform up and down piercing movements. The spindle angle, as a pulse signal, refers to the instantaneous angular position of the embroidery machine spindle when it rotates around its own axis. It is used to indicate the precise action phase of key execution components such as the embroidery needle (from the highest point of the spindle at 0° to the lowest point of the shuttle picking up the thread after piercing the fabric).

[0066] Spindle speed refers to the rotational speed of the embroidery machine's spindle, specifically defined as the number of rotations the spindle makes per unit time. Optionally, the spindle speed can be determined by the time it takes for the spindle angle to change and the commands issued by the main control module that controls the metal spring wire embroidery device. For example, the actual spindle speed is calculated based on the total time it takes for the spindle to complete one rotation, and then the preset speed in the commands issued by the main control module is obtained. Finally, the final spindle speed is calculated by weighting the actual speed and the preset speed (e.g., assigning each speed 50% weight). This balances the actual operating conditions of the spindle with the preset control objectives, ensuring the accuracy and stability of the spindle speed.

[0067] For example, the spindle angle of the embroidery machine can be read in real time by the spindle encoder, providing a precise timing reference for the subsequent wire feeding angle calculation. This ensures that the metal spring wire segment arrives at the needle insertion position accurately before the needle goes down, ensuring the coordination and consistency between the auxiliary material delivery and the embroidery action. This avoids problems such as misalignment of embroidery stitches and missed embroidery caused by deviations in the timing of wire feeding, thereby improving the stability and precision of the embroidery process.

[0068] S202: Calculate the wire feeding angle based on the first preset angle and the spindle speed; wherein, the first preset angle is used to indicate the spindle angle of the embroidery machine when the metal spring wire segment is fed to the needle position of the embroidery machine.

[0069] In this step, the wire feeding angle indicates the instantaneous angular position of the embroidery machine's main shaft when the wire feeding action is initiated. This ensures that the metal spring wire segment accurately reaches the needle insertion position before the needle strikes, and is a key parameter for ensuring precise coordination between the auxiliary material delivery and the embroidery action. The first preset angle indicates the angle of the embroidery machine's main shaft when the metal spring wire segment is delivered to the needle insertion position, i.e., the angle of the embroidery machine's main shaft when the wire feeding action is completed. For example, the first preset angle can be 0°, i.e., the needle is at its highest point.

[0070] For example, if the spindle speed of the embroidery machine obtained according to the method mentioned in S201 is nr / min, then the rotation angle (angular velocity) of the spindle per unit time is: By combining the wire feeding time, the spindle rotation angle compensation required for the wire feeding action can be calculated, that is, the angle by which the spindle will rotate during the wire feeding action. For example, if the spindle speed is 600 r / min and the angular velocity is... If the wire feeding time is 0.05s (taking the wire feeding distance as equivalent to a shift fork motor angle of 90° and an average conveying speed of 300r / min driven by the shift fork motor as an example), then the spindle rotational angular velocity compensation is: This translates to an equivalent angle of 180° (0.5 revolutions) within a 360° radius. Finally, using the spindle angle of the embroidery machine as a reference, subtract the angle compensation amount in the opposite direction (considering the spindle rotation direction; if the spindle rotates clockwise, perform the subtraction operation) to obtain the wire feeding angle. For example, if the spindle angle (first preset angle) of the embroidery machine is 0°, and the angle compensation amount is equivalent to 180°, then the wire feeding angle is 180°; if the spindle angle (first preset angle) of the embroidery machine is 0°, and the angle compensation amount is 90°, then the wire feeding angle is 270°.

[0071] By precisely calculating the wire feeding angle, effective support is provided for achieving precise coupling between the metal spring wire segment conveying action and the needle insertion timing.

[0072] In one possible implementation, correspondingly, in S103: feeding the metal spring wire segment to the needle position of the embroidery machine specifically includes:

[0073] S203: Determine whether the current needle of the embroidery machine is the needle corresponding to the needle mark, and whether the spindle angle has reached the wire feeding angle.

[0074] If so, then execute S204.

[0075] Understandably, the needle identifier corresponding to the metal spring wire in the instruction is used to clearly identify the specific needle in the embroidery machine that requires metal spring wire embroidery. This ensures that the length of metal spring wire required for the current needle insertion is the length of the previously cut metal spring wire segment, preventing embroidery defects caused by non-target needles accidentally triggering the wire feeding action. On the other hand, by ensuring that the spindle angle reaches the wire feeding angle, the timing of the wire feeding action and the needle insertion action is precisely matched.

[0076] S204: Initiate the wire feeding action to deliver the metal spring wire segment to the needle position of the embroidery machine. That is, if the current needle position of the embroidery machine is the needle corresponding to the needle mark and the spindle angle has reached the wire feeding angle, then initiate the wire feeding action to deliver the metal spring wire segment to the needle position of the embroidery machine.

[0077] As mentioned in S202, if the spindle angle (first preset angle) of the embroidery machine is 0°, the angle compensation is equivalent to 180°, and the wire feeding angle is 180°, then when the spindle of the embroidery machine rotates to 180°, the wire feeding action is started. After 0.05s of wire feeding time, the spindle of the embroidery machine rotates exactly to the 180° down-needling angle. If the spindle angle (first preset angle) of the embroidery machine is 0°, the angle compensation is 90°, and the wire feeding angle is 270°, then when the spindle rotates to 270°, the wire feeding action is started. After 0.05s of wire feeding time, the spindle of the embroidery machine rotates exactly to the 0° down-needling angle, and the metal spring wire segment arrives at the down-needle position simultaneously, thereby ensuring precise connection between the auxiliary material delivery and the embroidery action.

[0078] In one possible implementation, if the embroidery machine detects that the needle currently being inserted is the one corresponding to the needle identifier before the metal spring wire cutting process is completed, and the spindle angle has reached the wire feeding angle, then a system error indication message is pushed.

[0079] Understandably, the embroidery machine is currently using the needle corresponding to the needle's marking, and the spindle angle has reached the thread feeding angle, meeting the conditions for starting thread feeding. This indicates that this is the optimal time to start thread feeding. However, the cutting process of the metal spring wire must be completed before the thread feeding action is initiated to ensure that the delivered metal spring wire is a segment that meets the length requirements. Therefore, if the conditions for starting thread feeding are met before the metal spring wire cutting process is completed, it indicates a misalignment between the cutting action and the thread feeding sequence. If the thread feeding action continues at this time, it will result in the delivery of uncut whole threads or defective segments that are too short, leading to problems such as misalignment of embroidery stitches and equipment jamming. Therefore, an error indication message should be immediately pushed to the system, and the operation of the embroidery machine and the metal spring wire embroidery device should be suspended simultaneously. This allows maintenance personnel to troubleshoot potential faults in the cutting mechanism, detection components, or timing control logic, ensuring the accuracy of the embroidery process and the stability of equipment operation.

[0080] S205: After detecting that the embroidery needle of the embroidery machine has passed through the metal spring wire segment, control the wire feeding structure to reset.

[0081] Understandably, once the embroidery needle of the embroidery machine passes through the metal spring wire segment and reaches the fabric surface, it indicates that the metal spring wire segment has been precisely positioned and has formed an effective combination with the embroidery needle and regular embroidery thread. The embroidery thread has initially wrapped around the wire segment. Subsequently, by the return of the embroidery needle and the interweaving of the stitches, the metal spring wire segment can be firmly embroidered onto the fabric surface. At this point, the core conveying task of the wire feeding structure (clamping mechanism) has been completed, and there is no need to provide support or positioning for the current metal spring wire segment.

[0082] To prevent the wire feeding mechanism from mechanically interfering with the return motion of the embroidery needle and the fabric conveying motion in subsequent embroidery processes, and to prevent it from occupying the conveying path of the metal spring wire segment for the next stitch, thus preparing for the wire feeding of the next stitch, the wire feeding mechanism is controlled to reset and return to the contact point to prepare to receive the metal spring wire segment corresponding to the next stitch, so as to ensure the stability and continuity of the entire three-dimensional embroidery process.

[0083] The control method for the metal spring wire embroidery device provided in this application embodiment detects the spindle angle of the embroidery machine in real time and calculates the wire feeding angle based on the spindle angle. This controls the metal spring wire segment to start feeding at a precise moment, ensuring it arrives at the needle insertion position just before the needle pierces through. Finally, after detecting that the embroidery needle has passed through the metal spring wire segment, the wire feeding structure is controlled to return to a safe retraction angle, preparing for the next embroidery cycle. Through this method, precise connection between auxiliary material feeding and embroidery actions is achieved, ensuring the smoothness and safety of continuous embroidery operations and improving the automation, stability, and reliability of the metal spring wire embroidery process.

[0084] Figure 3 A flowchart illustrating the control method for a metal spring wire embroidery device provided in this application. Figure Three ,likeFigure 3 As shown, based on the above embodiment, in S204: after detecting that the embroidery needle of the embroidery machine has passed through the metal spring wire segment, the wire feeding structure is controlled to reset, specifically including:

[0085] S301: Obtain the spindle angle and spindle speed of the embroidery machine.

[0086] Its implementation process and technical effects are similar to those of S201, and will not be described in detail here.

[0087] S302: Calculate the retraction angle based on the second preset angle and the spindle speed; wherein, the second preset angle is used to indicate the spindle angle of the embroidery machine when the needle tip reaches the fabric surface.

[0088] In this step, the retraction angle refers to the pre-calibrated spindle angle of the embroidery machine based on its mechanical structure characteristics, needle return trajectory, and the safety distance for the wire feeding structure to reset. The key is to ensure that the wire feeding structure does not interfere with the needle, fabric, or other moving parts during retraction. The second preset angle indicates the spindle angle of the embroidery machine when the needle tip reaches the fabric surface. For example, the second preset angle could be 114°.

[0089] Alternatively, the formula for calculating the retraction angle can be expressed as: ,in, Indicates the retraction angle; This indicates a second preset angle, such as 114°; This indicates the spindle speed of the embroidery machine mentioned in S301; This indicates the delayed response time of the shift fork motor.

[0090] By precisely calculating the retraction angle, the risk of collision or interference with the embroidery needle, embroidery fabric, and other moving parts of the device during the resetting process is avoided.

[0091] S303: Determine whether the wire feeding action has been completed and whether the spindle angle has reached the retraction angle.

[0092] If so, then execute S304.

[0093] Understandably, the completion of the wire feeding action indicates that the core conveying task of the wire feeding structure (clamping mechanism) has been completed, and there is no need to provide support or positioning for the current metal spring wire segment. Furthermore, the spindle angle of the embroidery machine has reached the retraction angle, indicating that the embroidery needle of the embroidery machine has passed through the metal spring wire segment, the core embroidery stitch of the current stitch has been completed, and the embroidery needle has returned to a safe position.

[0094] S304: Controls the wire feeding structure to retract and reset, waiting for the next instruction.

[0095] In other words, if the wire feeding action has been completed and the spindle angle has reached the retraction angle, the wire feeding structure is controlled to retract and reset, waiting for the next instruction.

[0096] Understandably, when the wire feeding action is completed and the spindle angle has reached the retraction angle, the wire feeding structure is controlled to retract and reset along the original wire feeding path to prepare for the delivery of the metal spring wire segment for subsequent stitches, ensuring the smoothness of continuous embroidery operations.

[0097] The control method for the metal spring wire embroidery device provided in this application includes: firstly, acquiring the spindle angle and spindle speed of the embroidery machine; then, calculating the allowable retraction angle for the wire feeding structure to begin safe retraction based on a preset spindle angle (a second preset angle) when the needle tip contacts the fabric and the spindle speed. When the wire feeding action is completed and the spindle angle has reached the retraction angle, controlling the wire feeding structure to retract and reset, awaiting the next instruction. This method ensures the accuracy and safety of the wire feeding structure's reset timing, effectively preventing mechanical interference or collision between the wire feeding structure and the embroidery needle, the fabric being embroidered, or other moving parts during the reset process. It also prepares for continuous and smooth wire feeding operations for subsequent stitches, improving the automation, stability, and overall efficiency of the embroidery process.

[0098] Based on the above embodiments, in S102: cutting the metal spring wire segment of the corresponding length according to the instruction may specifically include:

[0099] 1) According to the instructions, control the wire pressing device and the guide tube to release and transport the metal spring wire.

[0100] As mentioned in S102, the wire cutting part of the control device of the metal spring wire embroidery device consists of three mechanisms, including a wire pressing device (pressure roller), a guide tube, and a cutter. The wire pressing device presses down the corresponding length of the metal spring wire according to the length of the current stitch indicated in the command, and holds the metal spring wire tightly by applying an appropriate clamping force. That is, it prevents the metal spring wire from shifting during subsequent wire cutting and conveying. After the wire holding is completed, the metal spring wire is assistedly conveyed to the clamping mechanism through the guide tube.

[0101] 2) When the metal spring wire released within the clamping area reaches the required length, control the cutter to cut the wire and obtain a metal spring wire segment of the corresponding length.

[0102] As mentioned in S102, when the length of the metal spring wire output in the clamping area reaches the length indicated in the instruction, the wire is cut by controlling the cutter to obtain the metal spring wire segment required for the current stitch.

[0103] Therefore, the metal spring wire segment of the specified length is cut according to the instruction. Specifically, this involves controlling the pressing device and the guide tube to work together to release and transport the metal spring wire, while simultaneously applying a moderate clamping force through the pressing device to prevent displacement of the metal spring wire. When the released metal spring wire within the clamping area reaches the length indicated in the instruction, the cutter is controlled to perform a cutting action, thereby obtaining a metal spring wire segment of the required length for the current stitch. This method ensures the accuracy and consistency of the length of each metal spring wire segment, effectively avoiding embroidery defects caused by a shortage of auxiliary materials, and further improving the automation reliability and finished product quality stability of the entire embroidery process.

[0106] The second processing module 402 is used to cut a metal spring wire segment of the required length according to the instruction when the instruction information indicates that a metal spring wire is needed.

[0107] The third processing module 403 is used to transport the metal spring wire segment to the needle position of the embroidery machine to complete the embroidery.

[0109] Obtain the spindle angle and spindle speed of the embroidery machine;

[0110] The wire feeding angle is calculated based on the first preset angle and the spindle speed; wherein, the first preset angle is used to indicate the spindle angle of the embroidery machine when the metal spring wire segment is fed to the needle position of the embroidery machine;

[0111] Calculate the wire feeding angle based on the spindle angle.

[0112] Correspondingly, the third processing module 403 is specifically used to start the wire feeding action if the current needle of the embroidery machine is the needle corresponding to the needle mark and the spindle angle reaches the wire feeding angle, so as to transport the metal spring wire segment to the needle position of the embroidery machine.

[0113] In one possible implementation, the control device 40 of the metal spring wire embroidery device further includes:

[0114] The fifth processing module 405 is used to control the wire feeding structure to reset after detecting that the embroidery needle of the embroidery machine has passed through the metal spring wire segment.

[0115] In one possible implementation, the second processing module 402 is specifically used for:

[0116] According to the instructions, the control wire pressing device and the guide tube release and deliver the metal spring wire;

[0117] When the metal spring wire released from the clamping area reaches the required length, the cutter is controlled to cut the wire, resulting in a metal spring wire segment of the corresponding length.

[0118] In one possible implementation, the control device 40 of the metal spring wire embroidery device further includes:

[0119] The sixth processing module 406 is used to push a system error indication message if, during the metal spring wire cutting process, it is detected that the needle currently being cut by the embroidery machine is the needle corresponding to the needle identifier and the spindle angle has reached the wire feeding angle.

[0120] In one possible implementation, the fifth processing module 405 is specifically used for:

[0121] Obtain the spindle angle and spindle speed of the embroidery machine;

[0122] The retraction angle is calculated based on the second preset angle and the spindle speed; wherein, the second preset angle is used to indicate the spindle angle of the embroidery machine when the needle tip reaches the fabric surface;

[0123] If the wire feeding action has been completed and the spindle angle of the embroidery machine has reached the retraction angle, then control the wire feeding structure to retract and reset, waiting for the next instruction.

[0124] The control device of the metal spring wire embroidery device provided in this embodiment can execute the method provided in the above method embodiment. Its implementation principle and technical effect are similar, and will not be described again in this embodiment.

[0125] Figure 5 A schematic diagram of the control device for a metal spring wire embroidery device provided in this application. Figure Two ,like Figure 5 As shown, the control device 50 of the metal spring wire embroidery apparatus includes at least one processor 501 and a memory 502. Optionally, the control device 50 of the metal spring wire embroidery apparatus further includes a communication component 503. The processor 501, memory 502, and communication component 503 are connected via a bus 504.

[0126] In one possible implementation, the control device of the metal spring wire embroidery apparatus further includes a wire cutting section (wire pressing device, guide tube, cutter), a wire feeding structure, a clamping mechanism, a lifting mechanism, and a feeding section. The feeding section includes two position detection points (lower and upper). If the use of metal spring wire increases, leading to a decrease in material in the hopper, the detection spring will be pulled down to the lower position under gravity or material pressure. The lower detection point is triggered and sends a low material level signal, immediately activating the feeding mechanism to replenish material, gradually raising the material level in the hopper. The detection spring is then pushed back to the upper position. When the upper detection point is triggered, feeding stops, completing one replenishment cycle. Through this automatic detection and start-stop control, a continuous and stable material supply is ensured, and the material level is always maintained within a reasonable range between the upper and lower positions, preventing material shortages or overflows from affecting the production rhythm. The lifting mechanism can control the raising and lowering of the control device, facilitating operation when not in use.

[0127] In addition, the control device 50 of the metal spring wire embroidery device also has a missing wire error reporting function, specifically including:

[0128] 1) During the metal spring wire embroidery process, as the length of the metal spring wire segment corresponding to the length indicated in the cutting instruction accumulates, if the length of the accumulated metal spring wire segment has reached the preset wire shortage warning threshold, and the lower detection point of the feeding part has not yet been triggered, then it is determined that there is a shortage of material / wire, and a system error indication message is pushed.

[0129] 2) Increased use of metal spring wire leads to a decrease in material in the hopper. The detection spring is pulled down by gravity or material pressure, triggering the lower detection point of the feeding section and sending a low material level signal. This controls the feeding mechanism to start the replenishment action according to the preset feeding cycle. However, during the replenishment process of the preset feeding cycle, the upper detection point of the feeding section is never triggered, indicating that although the feeding mechanism has performed the replenishment action, no actual metal spring wire has been delivered to the required position. This confirms a material shortage / wire shortage and sends an error indication message to the system.

[0130] While sending out system error message, the operation of the control devices of the embroidery machine and the metal spring wire embroidery device is suspended to remind maintenance personnel to check for material replenishment or handle conveying faults in a timely manner, so as to avoid process defects such as missing embroidery stitches and disordered stitches due to insufficient silk thread supply, and to ensure the quality of embroidery products and the safe operation of equipment.

[0131] In the specific implementation process, at least one processor 501 executes the computer execution instructions stored in the memory 502, causing at least one processor 501 to perform the above-described method. The specific implementation process of the processor 501 can be found in the above-described method embodiments, and its implementation principle and technical effects are similar; therefore, it will not be repeated here.

[0136] Understandably, different specifications can be understood as different parameter types of metal spring wire, such as different thicknesses, materials, colors, elasticity, etc. In practical applications, if multiple specifications of metal spring wire need to be used for embroidery, multiple control devices for metal spring wire embroidery devices can be equipped. Each control device of the metal spring wire embroidery device is supplied with a specific specification of metal spring wire, and each independently performs actions such as picking up, cutting, and feeding the wire, and delivers the corresponding specification of metal spring wire segments to the embroidery machine, thereby realizing the coordinated use of multiple specifications of metal spring wire in embroidery operations.

Alternatively, the processor and the readable storage medium can exist as discrete components in a device.

For example, multiple units or components may be combined or integrated into another system, or some features may be ignored or not executed.
