Detailed Implementation

[0027] Embodiments of the present invention are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.

[0028] In the description of this invention, it should be understood that the orientation descriptions, such as up, down, etc., are based on the orientation or positional relationship shown in the drawings and are only for the convenience of describing this invention and simplifying the description, and are not intended to indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this invention.

[0029] In the description of this invention, "several" refers to one or more, and "multiple" refers to two or more. The use of "first" and "second" is for distinguishing technical features only and should not be construed as indicating or implying relative importance, or implicitly indicating the number of indicated technical features, or implicitly indicating the order of the indicated technical features.

[0030] In the description of this invention, unless otherwise explicitly defined, terms such as setting, installing, and connecting should be interpreted broadly, and those skilled in the art can reasonably determine the specific meaning of the above terms in this invention in conjunction with the specific content of the technical solution.

[0031] Reference Figures 1 to 9 As shown, a first aspect of the present invention provides an embroidery frame type identification mechanism, which includes a support plate component 6.5 constructed on the embroidery frame 6, one or more detection elements 12.1, and a control module.

[0032] The tray member 6.5 has one or more trigger parts; the trigger parts can be notches or protrusions. In this embodiment, the trigger parts are located on the edge side of the tray member 6.5 and protrude from the edge side. It should be noted that the number and / or position of the trigger parts differ for different sizes of embroidery frames 6. Embroidery frames 6 of the same size use the same number and position of trigger parts, and the type of embroidery frame 6 can be identified based on the number and position of the trigger parts. In addition, different categories of embroidery frames 6 can also be distinguished based on the difference in the number and / or position of the trigger parts, not limited to the size of the embroidery frame 6. For example, embroidery frames 6 of the same size may be divided into different categories because they are adapted to different embroidery objects.

[0033] One or more detection elements 12.1 are disposed on the embroidery frame 6' on which the embroidery frame 6 is mounted. The one or more detection elements 12.1 directly or indirectly detect the embroidery frame 6 through a trigger. In this embodiment, the detection element 12.1 is a photoelectric sensor. Of course, in other embodiments, a micro switch or other existing known detection elements 12.1 can be used. Specifically, the detection element 12.1 emits light and forms a detection area. When the embroidery frame 6 is mounted on the embroidery frame 6', the trigger moves with the embroidery frame 6 to the detection area of ​​the corresponding detection element 12.1. After the reflected light beam is captured by the receiving end of the sensor, a corresponding detection signal is generated. It should be noted that the arrangement position of the detection element 12.1 corresponds one-to-one with the preset position of the trigger. Each trigger has a dedicated detection element 12.1 to match it, ensuring that triggers at different positions can be accurately detected. In another implementation, when the trigger part is a groove, when the trigger part moves with the embroidery frame 6 to the detection area of ​​the corresponding detection element 12.1, the detection beam can pass through the trigger part normally, while other detection beams are blocked by the solid parts on both sides of the trigger part, and the part through which the detection beam passes normally forms a detection signal.

[0034] The control module identifies the type of embroidery frame 6 based on the detection signals from one or more detection elements 12.1. The control module has pre-stored trigger part coding information corresponding to different sizes of embroidery frames 6. For example, for a 30cm×30cm square embroidery frame 6, the trigger part layout corresponds to code "101," and for a 20cm×40cm rectangular embroidery frame 6, the trigger part layout corresponds to code "011." Upon receiving a signal transmitted from the detection element 12.1, the control module converts the signal combination into a corresponding code and compares it with the pre-stored code library. Once a matching code is identified, the type of embroidery frame 6 can be quickly determined, and the corresponding embroidery parameters, such as embroidery range and stitch length adjustment threshold, can be automatically retrieved without manual setting.

[0035] It is worth noting that by detecting the trigger part of the embroidery frame 6 through the detection element 12.1, the control module can identify the type of embroidery frame 6 based on the detection signal of the detection element 12.1. This eliminates the need for manual input of the embroidery frame 6 parameters, effectively avoiding the problem of mismatched embroidery parameters caused by human error, significantly reducing the risk of damage to the embroidery frame 6 or the embroidery machine, while simplifying the operation process and improving the overall efficiency and automation of embroidery operations.

[0036] Reference Figure 4 and Figure 10 As shown, in some specific embodiments of the present invention, one or more trigger modules 13 are also included, configured on the embroidery frame 6'; in response to the embroidery frame 6 being loaded onto the embroidery frame 6', one or more trigger units trigger one or more corresponding trigger modules 13 to cause the trigger modules 13 to be detected by one or more detection elements 12.1.

[0037] In this embodiment, the triggering unit first triggers the triggering module 13, and the triggering module 13 then triggers the detection element 12.1. The triggering unit indirectly triggers the detection element 12.1 through the triggering module 13. The triggering module 13 acts as a relay, effectively extending the triggering distance between the triggering unit and the detection element 12.1, reducing the probability of other structures accidentally triggering the detection element 12.1, and avoiding excessively dense distribution of parts in local areas, which is more conducive to the assembly and disassembly of various parts.

[0038] Reference Figure 5 , Figure 6 and Figure 7 As shown, in some specific embodiments of the present invention, the trigger module 13 includes a sliding trigger 13.1. In response to the embroidery frame 6 being loaded onto the embroidery frame 6', one or more triggering parts push the corresponding sliding trigger 13.1 so that the sliding trigger 13.1 is detected by one or more detection elements 12.1.

[0039] In this embodiment, the sliding trigger 13.1 adopts a linear sliding transmission method. The sliding trigger 13.1 has a simple structure and high transmission accuracy. At the same time, the sliding trigger 13.1 can convert the rotational motion of the trigger part on the embroidery frame 6 into linear motion, which can ensure that the position information of the trigger part is accurately transmitted to the detection element 12.1, improve detection accuracy, and reduce the probability of false triggering.

[0040] Reference Figure 5 , Figure 6 and Figure 7 As shown, in some specific embodiments of the present invention, the sliding trigger 13.1 is provided with a reset force by one or more elastic reset members 13.5 in a direction tending to move away from one or more detection elements 12.1.

[0041] It is understandable that during the loading of the embroidery frame 6 onto the embroidery frame 6', the sliding trigger 13.1 is pushed and moves towards the detection element 12.1. The elastic reset element 13.5, affected by the movement of the sliding trigger 13.1, stores elastic potential energy. When the locking force between the embroidery frame 6 and the embroidery frame 6' disappears, the elastic reset element 13.5 releases its elastic potential energy and pushes the sliding trigger 13.1 away from the detection element 12.1. Both the sliding trigger 13.1 and the detection element 12.1 reset to their unloaded state, thus achieving automatic reset of the sliding trigger 13.1 and the detection element 12.1. Furthermore, because the locking force between the embroidery frame 6 and the embroidery frame 6' disappears, the elastic reset element 13.5 can also, to a certain extent, push the embroidery frame 6 to separate from the embroidery frame 6'.

[0042] In this embodiment, the elastic reset member 13.5 is disposed between the sliding trigger member 13.1 and the detection element 12.1, and is compressed when the embroidery frame 6 is loaded onto the embroidery frame 6'. In another embodiment, the elastic reset member 13.5 is disposed on the side of the sliding trigger member 13.1 away from the detection element 12.1, and is stretched when the embroidery frame 6 is loaded onto the embroidery frame 6'. The elastic reset member 13.5 is a compression spring. When there are multiple detection elements 12.1, multiple sliding trigger members 13.1, and multiple elastic reset members 13.5, each detection element 12.1, each sliding trigger member 13.1, and each elastic reset member 13.5 corresponds one-to-one.

[0043] Reference Figure 5 , Figure 6 and Figure 7 As shown, in some specific embodiments of the present invention, the trigger module 13 includes a retainer 13.4, one or more sliding triggers 13.1 slidably mounted on the retainer 13.4, and one or more elastic reset members 13.5 acting between the corresponding one or more sliding triggers 13.1 and the retainer 13.4.

[0044] It is understandable that by limiting the sliding trigger 13.1 and the elastic reset 13.5 by retaining member 13.4, the use of sliding trigger 13.1 and elastic reset 13.5 becomes more reliable. Furthermore, sliding trigger 13.1 and elastic reset 13.5 can deform along a preset direction, making the movement of sliding trigger 13.1 more stable and the deformation of elastic reset 13.5 more stable, which is more conducive to extending the service life of elastic reset 13.5.

[0045] In this embodiment, the retainer 13.4 includes a retaining body and a stop portion. The retaining body has multiple parallel through holes. The stop portion is located at one end of each through hole. A sliding trigger 13.1 passes through one through hole and is able to pass through the stop portion to slide along the axial direction of the through hole toward the detection element 12.1. An elastic reset member 13.5 is sleeved on the sliding trigger 13.1, with one end connected to or abutting against the sliding trigger 13.1 and the other end connected to or abutting against the stop portion. The retaining body includes a first part and a second part that can be joined together, with a through hole and a stop portion formed between the first part and the second part. For example, the side of the first part corresponding to the second part has a first groove and a first half portion located at one end of the first groove; the side of the second part corresponding to the first part has a second groove and a second half portion located at one end of the second groove; the first groove and the second groove together form a through hole; and the first half portion and the second ring portion form a stop portion.

[0046] Reference Figure 5 , Figure 6 and Figure 7 As shown, in some specific embodiments of the present invention, the sliding trigger 13.1 includes a sliding part and a first limiting part. The sliding part is slidably mounted on the retaining member 13.4. The first limiting part is connected to the sliding part. The retaining member 13.4 has a second limiting part. The first limiting part and the second limiting part limit each other to limit each other so that the sliding part slides relative to the retaining member 13.4 within a preset range.

[0047] It is worth understanding that the sliding trigger 13.1 slides within a preset range through the limiting cooperation of the first limiting part and the second limiting part. This can effectively prevent the sliding part from sliding excessively due to the elastic force of the elastic reset part 13.5 or the thrust of the trigger part, and avoid collision damage with the detection element 12.1 or other parts of the embroidery frame 6'. At the same time, it can also ensure that the sliding trigger 13.1 is always within the effective detection range of the detection element 12.1, and ensure the stable output of the detection signal.

[0048] In this embodiment, the first limiting part protrudes from the outer peripheral surface of the sliding part, and the second limiting part is a limiting through hole provided on the retaining member 13.4. The limiting through hole is a strip-shaped hole, and the length direction of the limiting through hole is the axial direction of the through hole. At least a portion of the first limiting part is located inside the limiting through hole and can stop and limit the sliding part along the axial direction of the through hole with the two ends of the strip-shaped limiting through hole. One end of the elastic reset member 13.5 abuts against the first limiting part, which can be a positioning pin. As another embodiment, there are two first limiting parts and two second limiting parts. The two first limiting parts are respectively provided at both ends of the sliding part along the axial direction of the through hole, and the two second limiting parts are provided at both ends of the retaining body along the axial direction of the through hole. The first limiting part and the second limiting part located at the same end can abut and limit the sliding part, thereby restricting the sliding of the sliding part.

[0049] Reference Figure 5 , Figure 6 and Figure 7 As shown, in some specific embodiments of the present invention, the sliding trigger 13.1 includes a sliding part and a part to be detected. The part to be detected is connected to the sliding part. One end of the sliding part can directly or indirectly abut against one or more trigger parts and be pushed by the trigger parts so that the part to be detected is detected by the detection element 12.1.

[0050] In this embodiment, the detection element 12.1 can also employ a visual recognition method. The part to be detected can be a coating or mark of different colors. By visually recognizing the part to be detected, the identification of the six types of embroidery frames can be achieved. Specifically, the part to be detected can have coatings of various colors distributed sequentially along the axial direction of the through hole. When the trigger part of different lengths triggers the part to be detected, it will correspond to different numbers of colors or different numbers of marks, thereby achieving the identification of the six types of embroidery frames.

[0051] Reference Figure 5 , Figure 6 , Figure 7 and Figure 8As shown, in some specific embodiments of the present invention, the detection element 12.1 is used to detect the number and / or position of the trigger parts being pushed. Specifically, different types of embroidery frames 6 have different numbers of trigger parts, or different types of embroidery frames 6 have the same number of trigger parts but different positions, or different types of embroidery frames 6 have different numbers of trigger parts and different positions. The detection element 12.1 detects the number and / or position of the trigger parts being pushed, converts the detected signal combination into a corresponding code, and then compares and matches it with the code library pre-stored in the control module, thereby accurately identifying the type of embroidery frame 6. For example, when two trigger parts are detected being pushed in the left and middle positions respectively, the corresponding code is "110", and the control module can determine that this is a 25cm×35cm embroidery frame 6 suitable for silk embroidery after comparison; if three trigger parts are detected being pushed in the left, middle, and right positions, the corresponding code is "111", then it can be identified as a 35cm×35cm embroidery frame 6 suitable for heavy cotton and linen materials. This multi-dimensional detection method can not only distinguish between embroidery frames of different sizes, but also identify special embroidery frames of the same size that are adapted to different embroidery materials, greatly improving the accuracy of recognition and the range of adaptation.

[0052] Reference Figure 9 As shown, in some specific embodiments of the present invention, one or more triggering parts can be detected by one or more detection elements 12.1.

[0053] It is worth noting that the trigger unit is directly detected by the detection element 12.1, eliminating the intermediate trigger module 13 structure. This not only simplifies the number of components in the entire identification mechanism and reduces manufacturing costs, but also reduces potential failure points in the transmission process, improving the response speed and stability of the detection. During actual assembly, the embroidery frame 6 is directly pushed to the preset position of the embroidery frame 6', and the trigger unit simultaneously enters the detection area of ​​the corresponding detection element 12.1, eliminating the need for additional relay transmission steps and making detection faster. At the same time, the direct detection method also reduces detection errors caused by wear and displacement of the trigger module 13, effectively ensuring the continuity of the embroidery operation.

[0054] Reference Figure 1 , Figure 2 and Figure 3 As shown, in some specific embodiments of the present invention, the tray member 6.5 is constructed on the side of the embroidery frame 6, and a trigger portion is constructed on the side of the tray member 6.5, the trigger portion including a trigger protrusion 6.511. In this embodiment, the tray member 6.5 includes a tray base 6.50 constructed on the lower frame 6.2 of the embroidery frame 6, and a metal tray 6.51 mounted on the tray base 6.50, the trigger protrusion 6.511 being constructed on the metal tray 6.51.

[0055] Reference Figure 1 , Figure 2 and Figure 3As shown, a second aspect of the present invention provides an embroidery machine, which includes a frame and an embroidery frame type identification mechanism as described in the first aspect, wherein the embroidery frame 6' is disposed on the frame.

[0056] It is worth noting that the embroidery machine adopts the embroidery frame type recognition mechanism in the first aspect embodiment. The embroidery machine can automatically identify the type of embroidery frame 6 loaded, eliminating the need for manual setting of the embroidery frame 6 parameters. This avoids problems such as misalignment of embroidery patterns, damage to the embroidery frame 6 or the machine caused by human input errors, and simplifies the operation process. Even inexperienced operators can quickly get started, significantly improving the automation level and production efficiency of embroidery operations. At the same time, the embroidery frame type recognition mechanism has strong adaptability and can be compatible with various specifications of embroidery frames 6, greatly expanding the applicable scenarios of the embroidery machine and better meeting diverse embroidery processing needs.

[0057] Reference Figure 10 and Figure 11 As shown, in some specific embodiments of the present invention, the tray member 6.5 is constructed with a first latching part 6.512; the embroidery frame 6' is configured with a first latching part 15.1 and an embroidery frame locking device 14; wherein, the embroidery frame 6 is latched into the first latching part 15.1 through the first latching part 6.512 and rotates around it, and is detachably coupled to the embroidery frame 6' through the embroidery frame locking device 14; wherein, during the rotation of the embroidery frame 6, one or more detection elements 12.1 directly or indirectly detect the embroidery frame 6 through a triggering part, and the control module identifies the type of embroidery frame 6 based on the detection signals of one or more detection elements 12.1.

[0058] It is understandable that the embroidery frame 6 is loaded onto the embroidery frame 6' by rotating the support plate component 6.5. During the rotation, the embroidery frame 6 triggers the detection signal of the detection element 12.1 through the trigger part of the support plate component 6. The control module identifies the type of embroidery frame 6 through the detection signal. The loading and identification of the embroidery frame 6 are achieved through the same loading step, eliminating the need for a separate identification operation, further simplifying the overall workflow. Specifically, the operator only needs to align the first locking part 6.512 of the embroidery frame 6 with the first locking part 15.1 of the embroidery frame 6' and rotate the embroidery frame 6 to complete the initial locking. During this rotation, the trigger part on the side of the embroidery frame 6 pushes the sliding trigger 13.1 into the detection range. The detection element 12.1 generates a detection signal and transmits it to the control module. When the embroidery frame 6 is rotated into place and fixed by the embroidery frame locking device 14, the control module has also completed the identification of the type of embroidery frame 6 and the call of the corresponding embroidery parameters, simplifying the assembly process and improving assembly efficiency.

[0059] In this embodiment, the first latching portion 6.512 is notched and connects to the side of the support plate member 6.5 along the first direction. The shape of the first latching portion 6.512 can be semi-circular, rectangular, or a combination of various shapes. The embroidery frame 6' is equipped with a first latching portion 15.1 and an embroidery frame locking device 14. The first latching portion 15.1 is columnar, and the embroidery frame 6 is inserted into the outer peripheral surface of the first latching portion 15.1 through the first latching portion 6.512 and rotates around the outer peripheral surface of the first latching portion 15.1. The first latching portion 15.1 can be cylindrical, elliptical, or other columnar structures. The embroidery frame locking device 14 plays a locking role. When the embroidery frame 6 rotates to a preset position around the first latch 15.1 via the first latch 6.512, the embroidery frame locking device 14 locks the embroidery frame 6, and the embroidery frame 6 and the embroidery frame 6' remain relatively fixed. At this time, the embroidery machine can embroider the embroidery frame 6. Similarly, the embroidery frame locking device 14 can also unlock the embroidery frame 6 under preset conditions, so that the embroidery frame 6 and the embroidery frame 6' can be separated from each other, and the embroidery frame 6 can be disassembled.

[0060] Reference Figure 10 and Figure 11 As shown, in some specific embodiments of the present invention, the trigger part is located on the adjacent side of the side where the first latching part 6.512 is located. In this embodiment, the first latching part 6.512 rotates around the first latching part 15.1. The first latching part 6.512 is located at the center of rotation, and the range of motion of the first latching part 6.512 is limited. The trigger part is located on the adjacent side of the side where the first latching part 6.512 is located, so that the trigger part is a certain distance away from the center of rotation, and the range of motion of the trigger part is larger, which is more conducive to the trigger part triggering the detection element 12.1 or the trigger module 13.

[0061] Reference Figure 10 and Figure 11 As shown, in some specific embodiments of the present invention, the tray member 6.5 is provided with a second locking part 6.513; the embroidery frame 6' is provided with a second locking part 15.2; wherein, the embroidery frame 6 is engaged with the first locking part 15.1 by the first locking part 6.512 and rotates around it so that the second locking part 6.513 is engaged with the second locking part 15.2, and is detachably coupled to the embroidery frame 6' by the embroidery frame locking device 14, so that the second locking part 6.513 is kept engaged in the second locking part 15.2.

[0062] In this embodiment, the second locking portion 6.513 is notched and connects to the side of the support plate member 6.5 along a second direction, which is perpendicular to the first direction. The shape of the second locking portion 6.513 can be semi-circular, rectangular, or a combination of these shapes. The shape of the second locking portion 6.513 can be the same as or different from the shape of the first locking portion 6.512. The second locking portion 15.2 is also columnar. During the rotation of the embroidery frame 6, the second locking portion 6.513 engages with the second locking portion 15.2, and the two portions abut against each other along the rotation direction, thereby restricting the continued rotation of the embroidery frame 6. When the second locking part 6.513 and the second locking part 15.2 abut against each other, the embroidery frame 6 rotates to a preset position. At this preset position, the embroidery frame locking device 14 locks the embroidery frame 6 and keeps the second locking part 6.513 and the second locking part 15.2 abutting against each other along a second direction. The second locking part 6.513 and the second locking part 15.2 restrict the embroidery frame 6 from moving along the second direction at the preset position, resulting in a better locking effect for the embroidery frame 6 and preventing it from shifting during embroidery, further improving embroidery accuracy. Meanwhile, at this preset position, the first locking part 6.512 and the first locking part 15.1 abut against each other along a first direction, restricting the embroidery frame 6 from moving along the first direction at the preset position.

[0063] The trigger unit is located on the same side as the second latching part 6.513. When the second latching part 6.513 engages with the second latching part 15.2, the trigger unit has already triggered the detection element 12.1. The cooperation between the second latching part 6.513 and the second latching part 15.2 can also limit the movement stroke of the trigger unit, ensuring that the relative position of the sliding trigger 13.1 and the detection element 12.1 remains stable, and avoiding fluctuations in the detection signal due to the shaking of the embroidery frame 6. Specifically, when the second latching part 6.513 engages with the second latching part 15.2, the stroke of the trigger unit pushing the sliding trigger 13.1 exactly reaches the preset detection position. At this time, one end of the first limiting part and the second limiting part abuts, and the elastic reset part 13.5 is in a preset compressed or stretched state. The detection element 12.1 can stably capture the signal of the part to be detected, providing a reliable basis for the accurate identification of the control module.

[0064] A third aspect of the present invention provides a method for identifying embroidery frames, including an embroidery frame type identification mechanism of the first aspect embodiment or an embroidery machine of the second aspect embodiment. The steps of the embroidery frame identification method include: embroidery frame 6 is assembled on embroidery frame 6'; a triggering part directly or indirectly triggers the detection signal of one or more detection elements 12.1; a control module receives the detection signal and identifies the type of embroidery frame 6 according to the detection signal.

[0065] It is understandable that by employing the embroidery frame type identification mechanism in the first aspect embodiment or the embroidery machine in the second aspect embodiment, automatic identification of the type of embroidery frame 6 is achieved through the linkage between the trigger part and the detection element 12.1 during the assembly process of the embroidery frame 6. This eliminates the need for manual input of embroidery frame 6 parameters, avoiding the problem of mismatched embroidery parameters caused by human error, and effectively reducing the risk of embroidery frame 6 offset, embroidery pattern misalignment, or even equipment damage. Simultaneously, the identification process is synchronized with the embroidery frame 6 assembly process, requiring no additional steps, greatly simplifying the workflow, shortening preparation time, and significantly improving the automation level and overall efficiency of embroidery operations. The trigger part layout varies for different specifications of embroidery frames 6; the detection element 12.1 can accurately identify the type of embroidery frame 6 based on different combinations of detection signals, demonstrating strong adaptability and meeting diverse embroidery processing needs, further expanding the applicable scenarios of the equipment.

[0066] The following is an exemplary embodiment, which is described in detail below: The embroidery frame type identification mechanism includes: a support plate member 6.5 constructed on the side of the embroidery frame 6, one or more detection elements 12.1, one or more sliding triggers 13.1, and a control module; the support plate member 6.5 has one or more trigger protrusions 6.511 on its side, one or more detection elements 12.1 are disposed on the embroidery frame 6' on which the embroidery frame 6 is loaded, and one or more sliding triggers 13.1 are disposed on the embroidery frame 6' and are provided with a reset force by one or more elastic reset members 13.5 to move away from one or more detection elements 12.1; in response to the embroidery frame 6 being loaded onto the embroidery frame 6', one or more trigger protrusions 6.511 push the corresponding one or more sliding triggers 13.1 to be detected by one or more detection elements 12.1; the control module (not shown) identifies the type of embroidery frame 6 based on the detection signal of one or more detection elements 12.1.

[0067] Different types of embroidery frames 6 have different numbers and positions of trigger protrusions 6.511. When the embroidery frame 6 is loaded onto the embroidery frame 6', the trigger protrusions 6.511 trigger the corresponding sliding trigger 13.1. The detection element 12.1 feeds back a detection signal to the control module according to the corresponding triggered sliding trigger 13.1. The control module identifies the type of embroidery frame 6 based on the feedback signal.

[0068] Reference Figure 10 and Figure 11As shown, the detection element 12.1 includes a first detection element 12.11 and a second detection element 12.12, and the sliding trigger 13.1 includes a first sliding trigger 13.11 and a second sliding trigger 13.12. The first ends of the first sliding trigger 13.11 and the second sliding trigger 13.12 are opposite to the first detection element 12.11 and the second detection element 12.12. Two elastic reset members 13.5 separate the first sliding trigger 13.11 and the second sliding trigger 13.12 from the first detection element 12.11 and the second detection element 12.12 in a non-triggered state. For example, the embroidery frame 6 is configured in three categories. The first category of the embroidery frame 6 is configured with one trigger protrusion 6.511 corresponding to the first detection element 12.11; the second category of the embroidery frame 6 is configured with one trigger protrusion 6.511 corresponding to the second detection element 12.12; and the third category of the embroidery frame 6 is configured with two trigger protrusions 6.511 respectively corresponding to the first detection element 12.11 and the second detection element 12.12.

[0069] When the embroidery frame 6 is loaded onto the embroidery frame 6', if only the first detection element 12.11 detects a signal, the control module determines it to be a first-category embroidery frame; if only the second detection element 12.12 detects a signal, the control module determines it to be a second-category embroidery frame; if both the first detection element 12.11 and the second detection element 12.12 detect signals, the control module determines it to be a third-category embroidery frame. Thus, using two sets of detection elements 12.11, the identification of three categories of embroidery frames can be achieved.

[0070] In another embodiment, the detection element 12.1 may include a first detection element, a second detection element, and a third detection element (not shown in the figure), and the specific number of detection elements may be set according to actual production needs.

[0071] Reference Figure 10 and Figure 11 As shown, the device includes a trigger module 13 configured on the embroidery frame 6'. The trigger module 13 includes a first retainer 13.3 and a second retainer 13.2, one or more sliding triggers 13.1, and one or more elastic resets 13.5. The one or more sliding triggers 13.1 are slidably mounted between the first retainer 13.3 and the second retainer 13.2, and the one or more elastic resets 13.5 act between the corresponding one or more sliding triggers 13.1 and the first retainer 13.3.

[0072] The first retainer 13.3 and the second retainer 13.2 may be engaged by screws, and both may be mounted to the embroidery frame 6' by screws. The first end of one or more sliding triggers 13.1 is slidably movable relative to the first retainer 13.3 and the second retainer 13.2, and the second end of one or more sliding triggers 13.1 extends outward from the first retainer 13.3 or / and the second retainer 13.2 to receive a corresponding trigger protrusion 6.511.

[0073] In some embodiments, the first retainer 13.3 is configured with a slot 13.31 for mounting one or more mating surfaces of one or more resilient reset members 13.5. The first retainer 13.3 is configured with one or more slides 13.32 for mounting sliding trigger members 13.1 on one side of the mating surface. The sliding trigger members 13.1 are mounted on the corresponding slides 13.32. The sliding trigger members 13.1 are configured with a reset drive portion extending to the slot 13.31. The resilient reset members 13.5 act between the end of the slot 13.31 and the corresponding reset drive portion.

[0074] In one embodiment, the pallet member 6.5 includes a pallet base 6.50 constructed in the lower frame 6.2 of the embroidery frame 6, and a metal pallet 6.51 mounted on the pallet base 6.50, with trigger protrusions 6.511 constructed on the metal pallet 6.51.

[0075] In some embodiments, the detection element 13.1 is a photoelectric sensor; of course, in other embodiments, a microswitch or other known detection elements may be used.

[0076] In other embodiments, the sliding trigger 13.1 is not provided, and the detection element 13.1 directly detects the trigger protrusion 6.511. The control module identifies the type of embroidery frame 6 based on the detection signal of the detection element 13.1.

However, the present invention is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present invention.
