Description

[0001] This application relates to the field of embroidery technology, and in particular to a magnetic levitation embroidery machine and embroidery method. Background Technology

[0002] In existing technologies, the two-dimensional planar motion of the embroidery frame is generally achieved through mechanical transmission. Specifically, it typically uses a servo motor or stepper motor as power, and a transmission chain consisting of couplings, lead screws, slide rails, sliders, and various bearings to convert the rotational motion of the motor into the linear motion of the embroidery frame. During this process, there is a close and indispensable mechanical physical contact and coupling between the embroidery frame and the driving components, as well as within each transmission component. This contact is used to transmit force and motion, thereby guiding the embroidery frame to precisely position the fabric to each embroidery needle point.

[0003] However, during the high-speed, high-frequency reciprocating motion of the embroidery frame, friction is continuously generated between the contacting parts, which inevitably leads to mechanical wear, directly affecting the positioning accuracy of the embroidery frame and resulting in low equipment reliability.

[0025] In existing technologies, the two-dimensional planar motion of the embroidery frame is generally achieved through mechanical transmission. Specifically, it typically uses a servo motor or stepper motor as power, and a transmission chain consisting of couplings, lead screws, slide rails, sliders, and various bearings to convert the rotational motion of the motor into the linear motion of the embroidery frame. During this process, there is a close and indispensable mechanical physical contact and coupling between the embroidery frame and the driving components, as well as within each transmission component. This contact is used to transmit force and motion, thereby guiding the embroidery frame to precisely position the fabric to each embroidery needle point.

[0026] However, during the high-speed, high-frequency reciprocating motion of the embroidery frame, friction is continuously generated between the contacting parts, which inevitably leads to mechanical wear, directly affecting the positioning accuracy of the embroidery frame and resulting in low equipment reliability.

[0027] Therefore, this application provides a magnetic levitation embroidery machine to solve the problem of mechanical wear caused by friction.

[0028] Please see Figures 1-7 As shown, Figure 1 This is a schematic diagram of the structure of an embodiment of the magnetic levitation embroidery machine provided in this application; Figure 2 yes Figure 1 Schematic diagram of the structure of the intermediate drive component; Figure 3 This is a schematic diagram of another embodiment of the magnetic levitation embroidery machine provided in this application; Figure 4 yes Figure 3 Schematic diagram of the structure of the intermediate drive component; Figure 5 This is a schematic diagram of another embodiment of the magnetic levitation embroidery machine provided in this application; Figure 6 This is a schematic diagram of another embodiment of the magnetic levitation embroidery machine provided in this application; Figure 7 yes Figure 6 A schematic diagram of the moving part assembly; in this embodiment, the magnetic levitation embroidery machine 1 includes a frame 10, a stator assembly 20, an embroidery frame assembly (not shown), a moving part assembly 30, and a head assembly 40.

[0029] The stator assembly 20 is mounted on the frame 10; the embroidery frame assembly is mounted above the frame 10; the mover assembly 30 is mounted on the embroidery frame assembly and is correspondingly mounted to the stator assembly 20. The stator assembly 20 is used to cooperate with the mover assembly 30 to drive the embroidery frame assembly to suspend and move; and the head assembly 40 is mounted above the embroidery frame assembly and is used to embroider the embroidery on the embroidery frame assembly.

[0030] The stator assembly 20 is the stationary part of the drive system, which is usually composed of a series of carefully arranged electromagnetic coils to form a plane or track covering the required range of motion of the embroidery frame; the mover assembly 30 is the moving part of the drive system, which is usually composed of a permanent magnet (magnetic steel) or another set of coils; the stator assembly 20 and the mover assembly 30 constitute the drive system of the magnetic levitation embroidery machine 1.

[0031] The frame 10 serves as the basic support platform and skeleton of the magnetic levitation embroidery machine 1, providing a sturdy, stable, and precise mounting foundation. The frame 10 possesses high rigidity and stability to resist various vibrations and stresses experienced during the high-speed operation of the magnetic levitation embroidery machine 1. The head assembly 40 is the terminal actuator that performs the embroidery actions. The embroidery frame assembly is a frame structure used to tension and secure the embroidery (embroidery fabric). It typically consists of two adjustable parallel frame assemblies, which can be adjusted to clamp embroidery of different sizes, maintaining flatness and stable tension during the embroidery process.

[0032] In this embodiment, the magnetic levitation embroidery machine 1 also includes an auxiliary mechanism (not shown), such as a mechanism for fixing the auxiliary frame 10 and the head assembly 40.

[0033] In some embodiments, the stator assembly 20 is fixedly mounted on the frame 10, and the mover assembly 30 is fixedly mounted below or inside the embroidery frame assembly, corresponding vertically to the stator assembly 20. When the magnetic levitation embroidery machine 1 is powered on, the stator assembly 20 and the mover assembly 30 cooperate to generate a magnetic field, driving the embroidery frame assembly to levitate above the frame 10 and drive the embroidery frame assembly to move on the plane. At this time, the head assembly 40 located above the embroidery frame assembly embroiders the embroidery on the embroidery frame assembly. After the magnetic levitation embroidery machine 1 is powered off, the embroidery frame assembly can descend to the frame 10.

[0034] In this embodiment, the stator assembly 20 is disposed on the frame 10, and the mover assembly 30 is disposed on the embroidery frame assembly. The stator assembly 20 and the mover assembly 30 cooperate to drive the embroidery frame assembly to levitate and move. There is no direct physical contact between the embroidery frame assembly and the frame 10 with any mechanical connecting parts, thereby solving the problem of mechanical wear caused by friction. This not only greatly extends the service life of the core components of the drive system, but also improves the positioning accuracy of the embroidery frame assembly and significantly improves the reliability of the equipment.

[0035] According to some embodiments of this application, see Figure 1 and Figure 2 As shown, the stator assembly 20 of this embodiment includes a stator 21, which is disposed on the frame 10. The embroidery frame assembly (not shown) includes an embroidery frame (not shown), which is disposed above the frame 10. The mover assembly 30 includes a mover 31, which is integrated on the embroidery frame. The head assembly 40 includes a head 41, which is disposed above the embroidery frame.

[0036] In some embodiments, the stator 21 and the mover 31 are respectively a planar motor stator 21 and a planar motor mover 31. The stator 21 is fixed on the frame 10, and the mover 31 is integrated on the embroidery frame. The stator 21 drives the embroidery frame to suspend and move, thereby driving the embroidery frame to suspend and move. The machine head 41 is located at the upper part of the embroidery frame to embroider and sew the embroidery in the embroidery frame.

[0037] This embodiment integrates the mover 31 into the embroidery frame, while the stator 21 is fixed on the frame 10, eliminating the need for traditional multi-motor, multi-transmission chain, or complex linkage mechanisms. This greatly simplifies the mechanical structure of the system, significantly reduces the number of parts, not only lowers manufacturing costs but also fundamentally reduces potential failure points, thereby improving the reliability and stability of the entire machine. Furthermore, by directly driving the entire embroidery frame with a single mover 31, the most direct and efficient coupling between the power source and the load is achieved. The electromagnetic force does not need to go through complex mechanical conversion and distribution and acts directly on the embroidery frame with almost no loss, resulting in high transmission efficiency.

[0038] According to some embodiments of this application, the stator 21 is provided with a plurality of first coils (not shown in the figure), and the mover 31 is provided with a plurality of second coils (not shown in the figure) or a plurality of magnets (not shown in the figure). The second coils are arranged corresponding to the first coils, and the magnets are arranged corresponding to the first coils. The mover 31 is used to drive the embroidery frame to move by cooperating with the plurality of second coils or the plurality of magnets and the plurality of first coils.

[0039] The first coil and the second coil can be the same coil or different coils.

[0040] In some embodiments, the stator 21 is provided with a plurality of first coils and the mover 31 is provided with a plurality of second coils. When energized, the magnetic field generated by the mover 31 interacts with the magnetic field generated by the stator 21 to generate electromagnetic force, which drives the embroidery frame to levitate and move.

[0041] In some embodiments, the stator 21 is provided with a plurality of first coils, and the mover 31 is provided with a plurality of magnets. When the stator 21 is energized, the magnetic field generated therein interacts with the inherent magnetic field of the magnets to generate an electromagnetic force, which drives the embroidery frame to levitate and move.

[0042] According to some embodiments of this application, see Figure 3 and Figure 4 As shown, the stator assembly 20 of this embodiment includes at least one first-direction stator 22 and at least one second-direction stator 23. The at least one first-direction stator 22 is disposed on the frame 10 along the first direction, and the at least one second-direction stator 23 is disposed on the frame 10 along the second direction. The embroidery frame assembly (not shown) includes an embroidery frame (not shown), which is disposed above the frame 10. The mover assembly 30 includes at least one first-direction mover 32 and at least one second-direction mover 33. The first-direction mover 32 is disposed corresponding to the first-direction stator 22, and the second-direction mover 33 is disposed corresponding to the second-direction stator 23. The head assembly 40 includes a head 41, which is disposed above the embroidery frame, and the first direction and the second direction are perpendicular to each other.

[0043] Optionally, the first direction is the x-axis and the second direction is the y-axis. In other embodiments, the first direction is the y-axis and the second direction is the x-axis.

[0044] In some embodiments, one or more first-direction movers 32 are provided in the first direction of the embroidery frame, one or more second-direction movers 33 are provided in the second direction of the embroidery frame, one or more first-direction stators 22 are correspondingly provided in the first direction of the frame 10, and one or more second-direction stators 23 are correspondingly provided in the second direction of the frame 10; when energized, the electromagnetic force generated by the first-direction movers 32 and the first-direction stators 22 is used to drive the embroidery frame to move in the first direction, and the electromagnetic force generated by the second-direction movers 33 and the second-direction stators 23 is used to drive the embroidery frame to move in the second direction.

[0045] For example, such as Figure 3 and Figure 4As shown, two first-direction movers 32 are spaced apart in the first direction of the embroidery frame, and two second-direction movers 33 are spaced apart in the second direction of the embroidery frame, forming a rectangular frame; correspondingly, two first-direction stators 22 are spaced apart in the first direction of the machine frame 10, and two second-direction stators 23 are spaced apart in the second direction of the machine frame 10, forming a rectangular frame.

[0046] In this embodiment, by corresponding the first-direction mover 32 and the second-direction mover 33 with the first-direction stator 22 and the second-direction stator 23 respectively, the driving force (electromagnetic force) of the embroidery frame in the first and second directions is decoupled in terms of physical structure and electromagnetic field. During maintenance, the mover 31 or stator 21 in a specific direction can be inspected or replaced without disassembling or disturbing the entire drive system (motor assembly 30 and stator assembly 20), which greatly reduces the difficulty and cost of manufacturing and maintenance.

[0047] According to some embodiments of this application, see Figure 5 As shown, the stator assembly 20 of this embodiment includes a plurality of stators 21, which are spaced apart on the frame 10; the embroidery frame assembly (not shown) includes a plurality of embroidery frames (not shown), which are correspondingly arranged with the stators 21, and are located above the frame 10 and above the corresponding stators 21; the mover assembly 30 includes a plurality of movers 31, which are arranged on the corresponding embroidery frames; the head assembly 40 includes a plurality of head 41, which are arranged above the corresponding embroidery frames.

[0048] In some embodiments, the stator 21, embroidery frame, mover 31, and machine head 41 have a one-to-one correspondence, meaning that the embroidery frame is driven to levitate and move by a corresponding single mover 31, and the corresponding machine head 41 embroiders the embroidery on the embroidery frame. In other embodiments, each embroidery frame may be provided with multiple corresponding machine heads 41 to embroider the embroidery.

[0049] Each embroidery frame can be independently controlled to float and move, and can be used to embroider different embroidery products to meet the user's needs for simultaneous production of multiple varieties and small batches of embroidery products, or multiple embroidery frames can be combined and controlled in a coordinated manner to embroider larger embroidery products.

[0050] This embodiment sets up multiple independently controllable and independently operating actuators 31 and embroidery frames, allowing the machine head 41 to operate independently and simultaneously embroider different embroidery products, thus greatly improving production efficiency.

[0051] According to some embodiments of this application, see Figure 6 and Figure 7As shown, the stator assembly 20 of this embodiment includes a plurality of first-direction stators 22 and a plurality of second-direction stators 23. The plurality of first-direction stators 22 are disposed on the frame 10 along the first direction, and the plurality of second-direction stators 23 are disposed on the frame 10 along the second direction. The embroidery frame assembly (not shown) includes an embroidery frame (not shown), which is disposed above the frame 10. The mover assembly 30 includes a plurality of first-direction movers 32 and a plurality of second-direction movers 33. The first-direction movers 32 are disposed corresponding to the first-direction stators 22, and the second-direction movers 33 are disposed corresponding to the second-direction stators 23. The head assembly 40 includes a plurality of heads 41, which are spaced apart above the embroidery frame, and the first and second directions are perpendicular to each other.

[0052] In some embodiments, a plurality of first-direction movers 32 are provided in the first direction of the embroidery frame, a plurality of second-direction movers 33 are provided in the second direction of the embroidery frame, a plurality of first-direction stators 22 are provided in the first direction of the machine frame 10, and a plurality of second-direction stators 23 are provided in the second direction of the machine frame 10; after power is applied, the embroidery frame is driven to move in the first direction by the plurality of first-direction movers 32, and the embroidery frame is driven to move in the second direction by the plurality of second-direction movers 33, and the plurality of machine heads 41 embroider the embroidery.

[0053] For example, such as Figure 6 and Figure 7 As shown, six first-direction movers 32 are spaced apart along the first direction of the embroidery frame, and ten second-direction movers 33 are divided into five groups of two second-direction movers 33 in each group. The two second-direction movers 33 in each group form a small rectangular frame with the two adjacent first-direction movers 32, for a total of five small rectangular frames. Five machine heads 41 are respectively set above the five rectangular frames.

[0054] In this embodiment, multiple machine heads 41 are spaced apart above the embroidery frame. The combination of multiple machine heads 41 with a single embroidery frame constitutes a parallel operation mode of one frame with multiple heads. The multiple machine heads 41 can embroider in different areas of the embroidery completely synchronously and independently, which greatly improves production efficiency.

[0055] According to some embodiments of this application, the magnetic levitation embroidery machine 1 also includes a clamping device (not shown), which is disposed on the embroidery frame assembly and is used to clamp the embroidery.

[0056] The clamping methods of the clamping device include, but are not limited to, mechanical clamping, negative pressure adsorption clamping, or a combination of clamping.

[0057] This embodiment ensures that the embroidery remains tightly attached to the embroidery frame during high-speed starts and stops, sharp turns, and other violent dynamic processes, preventing local loosening, slippage, or deformation, thus eliminating embroidery errors caused by the movement of the embroidery.

[0058] According to some embodiments of this application, the magnetic levitation embroidery machine 1 further includes at least one distance detector (not shown), which is disposed on the embroidery frame assembly. The distance detector is used to measure the distance between the embroidery frame assembly and the frame 10 to adjust the levitation height of the embroidery frame assembly.

[0059] Among them, distance detectors include, but are not limited to, eddy current sensors, capacitive sensors, or laser rangefinders.

[0060] This embodiment, through the setting of a distance detector, can provide real-time feedback and rapid compensation, controlling the fluctuation of the embroidery frame's suspension height within a small range.

[0061] According to some embodiments of this application, the magnetic levitation embroidery machine 1 further includes at least one level (not shown), which is disposed on the embroidery frame assembly and is used to adjust the levelness of the embroidery frame assembly.

[0062] This embodiment eliminates the tilting of the embroidery frame caused by factors such as slight installation differences of the frame 10, ground settlement, uneven load distribution (such as localized heavy embroidery), or thermal deformation during long-term operation by setting a level. This avoids quality problems such as perspective distortion, disproportion, or uneven stitching caused by an uneven base.

[0063] In some embodiments, for a single-head embroidery machine with a smaller structure, the embroidery frame is driven to levitate and move by a single mover 31. Specifically, a stator 21 is fixed to the frame 10, a mover 31 is integrated into the embroidery frame, the embroidery frame is suspended above the frame 10, and a machine head 41 is positioned above the embroidery frame. For a single-head embroidery machine with a larger structure, one or more first-direction movers 32 and second-direction movers 33 are respectively provided in the first and second directions of the embroidery frame, and a corresponding number of first-direction stators 22 and second-direction stators 23 are placed at corresponding positions on the frame 10. For a multi-head embroidery machine, multiple independently controlled and independently operated movers 31 and embroidery frames can be provided. Specifically, multiple stators 21 are spaced apart on the frame 10, and corresponding movers 31 are set on the corresponding embroidery frames, so that the embroidery frames are suspended and moved by the corresponding movers 31 and stators 21. The corresponding machine head 41 is set above the corresponding embroidery frame. For a multi-machine head 41 large embroidery frame embroidery machine, multiple first-direction movers 32 and second-direction movers 33 are set according to the weight of the embroidery frame and the operating requirements. The same number of first-direction stators 22 and second-direction stators 23 are set at the corresponding positions on the frame 10. Multiple machine heads 41 are spaced apart above the embroidery frames, and multiple distance detectors and / or levels are set on the embroidery frames to adjust the suspension height and levelness of the embroidery frames.

[0064] In some embodiments, a first-direction mover 32 and a second-direction mover 33 are combined to form a mover 31; in this case, the mover 31 can move along the first direction or the second direction in the entire plane, thereby driving the embroidery frame to move along the first direction or the second direction; wherein the first direction and the second direction are perpendicular to each other.

[0065] Please see Figure 8 As shown, Figure 8 This is a flowchart illustrating an embodiment of an embroidery method provided in this application; the embroidery method of this embodiment is applied to the magnetic levitation embroidery machine 1 of the above embodiment, including: Step S110: The magnetic levitation embroidery machine 1 is powered on, and the embroidery frame assembly of the magnetic levitation embroidery machine 1 is suspended above the frame 10 of the magnetic levitation embroidery machine 1.

[0066] Step S120: The embroidery frame assembly is moved by the moving part assembly 30 and the stator assembly 20 of the magnetic levitation embroidery machine 1, and the head assembly 40 of the magnetic levitation embroidery machine 1 embroiders the embroidery on the embroidery frame assembly.

[0067] Step S130: After the embroidery is completed, the magnetic levitation embroidery machine 1 is powered off, and the embroidery frame assembly is lowered onto the frame 10.

[0068] In some embodiments, the embroidery frame assembly includes at least one embroidery frame, the stator assembly 20 includes at least one stator 21, and the mover assembly 30 includes at least one mover 31; the head assembly 40 includes at least one head 41; after the magnetic levitation embroidery machine 1 is powered on, the mover 31 on the embroidery frame and the stator 21 on the frame 10 cooperate to generate electromagnetic force, driving the embroidery frame to levitate above the frame 10, and the levitation height of the embroidery frame can be adjusted according to the embroidery work; for example, a distance detector and / or a level can be set on the embroidery frame to adjust different positions of the embroidery frame. The embroidery frame is placed at a certain levitation height, ensuring it is horizontal or level with the machine head 41. After the embroidery frame is levitated, the embroidered item (fabric or clothing) is placed on the embroidery frame, and the embroidery is held in place by the clamping device on the embroidery frame to prevent the embroidery from shifting and affecting the embroidery. After the embroidery is placed, the machine head 41 starts embroidering, and the mover 31 drives the embroidery frame to move along the first or second direction. After the embroidery is completed, the embroidery is removed, the magnetic levitation embroidery machine 1 is reset, the embroidery frame slowly descends onto the machine frame 10, and the magnetic levitation embroidery machine 1 is powered off.
