[0002] The garment guiding device is a device that uses mechanical transmission and electronic control system to realize the embroidery of patterns on the fabric by needle and thread. Its motion characteristics are short stroke, high acceleration and high frequency motion. The structural design needs to take into account the embroidery accuracy, efficiency and stability.

[0003] Existing guiding devices for X / Y axis translation typically employ screw drives. Screw drives are mechanical transmissions, which have limitations on the maximum acceleration during start-up and stop, making them unsuitable for high-acceleration, high-frequency motion. Repeatability is relatively low, and wear on the balls and screw over time leads to decreased accuracy. Furthermore, the exposed screw requires frequent maintenance and lubrication. This can easily result in low precision in embroidery, difficulty in increasing working frequency, and misalignment issues. Utility Model Content

[0015] The embodiments of this application have the following advantages: The guiding device provided by this application sets the second guide rail on the side of the first mover away from the first guide rail, so that when the first mover slides along the first guide rail in the first direction, it can drive the second guide rail to move synchronously in the first direction, thereby driving the second linear motor to move in the first direction through the first mover; In addition, since the second mover can slide along the second guide rail in the second direction, by connecting the external carrier to the second mover, the first linear motor and the second linear motor can achieve precise displacement control of the external carrier in the first and second directions, thereby achieving precise position control of the external carrier in the two-dimensional plane.

The terminology used herein in the template description is for the purpose of describing particular embodiments only and is not intended to be limiting of this application. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0026] like Figures 1 to 4 As shown, some embodiments of this application provide a guiding device having a first direction X, a second direction Y, and a third direction Z that are perpendicular to each other, mainly used to improve the accuracy and stability of the embroidery machine during the embroidery process.

[0027] The guiding device includes a first linear motor 100 and a second linear motor 200.

[0028] The first linear motor 100 includes a first guide rail 110, a first mover 120, a first magnetic scale 130, and a first magnetic head 140. The first mover 120 is slidably connected to the first guide rail 110 along the first direction X. It can be understood that the axial direction of the first guide rail 110 is parallel to the first direction X. The first mover 120 is slidably disposed on the first guide rail 110 and can slide on the first guide rail 110 along the first direction X.

[0029] The first magnetic scale 130 is disposed on one side of the first guide rail 110 along the second direction Y. The length direction of the first magnetic scale 130 is parallel to the first direction X. The first magnetic head 140 is disposed on the side of the first mover 120 facing the first magnetic scale 130, so as to collect the movement signal of the first mover 120. It should be noted that when the first mover 120 slides on the first guide rail 110 along the first direction X, it drives the first magnetic head 140 to move synchronously along the first direction X. During the movement along the first direction X, the first magnetic head 140 detects the periodic change of the magnetic field of the magnetic scale and outputs a sine wave or square wave signal. The displacement of the first mover 120 is calculated by the signal processing circuit, thereby determining the position and movement distance of the first mover 120. High-precision position detection of the first mover 120 is achieved through magnetic induction, improving control accuracy and reliability.

[0030] In addition, the second linear motor 200 includes a second guide rail 210, a second mover 220, a second magnetic scale 230, and a second magnetic head 240. The second guide rail 210 is disposed along the third direction Z on the side of the first mover 120 away from the first guide rail 110. The connection method between the second guide rail 210 and the first mover 120 includes any one of threaded connection, bolt connection, snap-fit, and adhesive connection, which can be specifically set according to the actual situation.

[0031] It is understandable that by detachably connecting the second guide rail 210 and the first mover 120, the ease of installation or removal between the first linear motor 100 and the second linear motor 200 is improved, so as to facilitate maintenance, cleaning or replacement.

[0032] In this embodiment, the second mover 220 is slidably connected to the second guide rail 210 along the second direction Y. It can be understood that the axial direction of the second guide rail 210 is parallel to the second direction Y, the second mover 220 is slidably disposed on the second guide rail 210, and the second mover 220 can slide on the second guide rail 210 along the second direction Y.

[0033] The second magnetic scale 230 is positioned on one side of the second guide rail 210 along the first direction X, with its length parallel to the second direction Y. The second magnetic head 240 is positioned on the side of the second mover 220 facing the second magnetic scale 230, allowing the second magnetic head 240 to acquire the movement signal of the second mover 220. It should be noted that when the second mover 220 slides along the second direction Y on the second guide rail 210, it drives the second magnetic head 240 to move synchronously along the second direction Y. During this movement, the second magnetic head 240 detects the periodic change in the magnetic field of the magnetic scale and outputs a sine wave or square wave signal. The signal processing circuit calculates the displacement of the second mover 220, thereby determining its position and movement distance. High-precision position detection of the second mover 220 is achieved through magnetic induction, improving control accuracy and reliability.

[0034] It should be noted that by setting the second guide rail 210 on the side of the first mover 120 away from the first guide rail 110, the first mover 120 can drive the second guide rail 210 to move synchronously along the first direction X while sliding along the first guide rail 110. Thus, the first mover 120 drives the second linear motor 200 to move along the first direction X. In addition, the second mover 220 can slide along the second direction Y on the second guide rail 210. By connecting the external carrier to the second mover 220, the first linear motor 100 and the second linear motor 200 can achieve precise displacement control of the external carrier in the first direction X and the second direction Y, thereby achieving precise position control of the external carrier in the two-dimensional plane.

[0035] For example, by applying the guiding device provided in this application to an embroidery machine, the translation mechanism in the embroidery machine can be replaced by the guiding device, thereby further improving the accuracy of the embroidery machine in positioning the needle and thread, improving the precision of the embroidery, and thus improving the quality of the embroidery.

[0036] like Figure 2 and Figure 3 As shown in some embodiments of this application, the first guide rail 110 is provided with first limiting plates 400 on two opposite sides along the first direction X. The first limiting plates 400 provide a limiting effect on the first moving part 120 during its sliding on the first guide rail 110, so as to prevent the first moving part 120 from disengaging from the first guide rail 110, thereby ensuring the stability and safety of the first moving part 120 during its sliding on the first guide rail 110.

[0037] Wherein, the projection of the first mover 120 along the first direction X onto the first limiting plate 400 at least partially overlaps with the first limiting plate 400, thereby providing obstruction and limitation for the first mover 120 through the overlapping portion between the first limiting plate 400 and the first mover 120.

[0038] like Figure 2 As shown, in some embodiments of this application, the first mover 120 is provided with first elastic members 500 on two opposite sides along the first direction X, so that the first elastic members 500 form a buffer effect between the first mover 120 and the first limiting plate 400 to prevent the first mover 120 from directly colliding with the first limiting plate 400 during the sliding process along the first guide rail 110, so that the first elastic members 500 provide elastic protection for the first mover 120 and ensure the integrity and service life of the first mover 120.

[0039] Wherein, the projection of the first elastic member 500 on the first limiting plate 400 along the first direction X partially overlaps with the first limiting plate 400, so that the overlapping portion of the first elastic member 500 and the first limiting plate 400 along the first direction X comes into contact with each other to form an elastic limiting structure.

[0040] In other embodiments, the projection of the first elastic member 500 on the first limiting plate 400 along the first direction X falls completely into the first limiting plate 400, thereby maximizing the contact area between the first elastic member 500 and the first limiting plate 400, and further improving the stability of the elastic contact between the first elastic member 500 and the first limiting plate 400.

[0041] The first elastic element 500 can be at least one of rubber, silicone, and spring, and can be specifically set according to the actual situation.

[0042] like Figure 1 and Figure 2 As shown, in some embodiments of this application, the first linear motor 100 further includes a first base 150, and the first guide rail 110 is disposed on one side of the first base 150 along the third direction Z. A first photoelectric switch 300 is provided on the side of the first base 150 facing the first guide rail 110. The first photoelectric switch 300 is spaced apart from the first guide rail 110 and faces the first guide rail 110. The first photoelectric switch 300 detects whether the mover has moved to a designated position during the sliding process along the first guide rail 110. Thus, the first photoelectric switch 300, the first magnetic scale 130 and the first magnetic head 140 form a closed-loop detection and control of the movement position and movement distance of the first mover 120 on the first guide rail 110, thereby ensuring the accuracy and stability of the detection of the movement position and movement distance of the first mover 120 on the first guide rail 110.

[0043] The position of the first photoelectric switch 300 on the first base 150 can be set according to the actual situation.

[0044] It should be noted that a photoelectric switch is a sensor that uses light signals to detect the position, motion state, or distance of an object. In linear motor systems, photoelectric switches mainly play a crucial role in position detection, limit protection, and origin calibration, ensuring the accuracy, safety, and reliability of motor operation.

[0045] In this embodiment, the first magnetic scale 130 is disposed on the side of the first base 150 facing the first guide rail 110, and the first magnetic scale 130 is disposed at intervals from the first guide rail 110 and the first mover 120 along the second direction Y, so as to ensure the stability and smoothness of the first mover 120 during its movement along the first guide rail 110.

[0046] like Figure 2 As shown in some embodiments of this application, the second guide rail 210 is provided with two opposite sides along the second direction Y, and the second limiting plate 700 provides a limiting effect on the second mover 220 during the sliding process on the second guide rail 210 to prevent the second mover 220 from disengaging from the second guide rail 210, so as to ensure the stability and safety of the second mover 220 during the sliding process on the second guide rail 210.

[0047] Wherein, the projection of the second mover 220 along the second direction Y onto the second limiting plate 700 at least partially overlaps with the second limiting plate 700, thereby providing obstruction and limitation for the second mover 220 through the overlapping portion between the second limiting plate 700 and the second mover 220.

[0048] like Figure 1 and Figure 2 As shown, in some embodiments of this application, the second mover 220 is provided with second elastic members 800 on two opposite sides along the second direction Y, so that the second elastic members 800 form a buffer effect between the second mover 220 and the second limiting plate 700, so as to prevent the second mover 220 from directly colliding with the second limiting plate 700 during the sliding process along the second guide rail 210, so as to provide elastic protection for the second mover 220 through the second elastic members 800, and ensure the integrity and service life of the second mover 220.

[0049] Wherein, the projection of the second elastic member 800 along the second direction Y onto the second limiting plate 700 partially overlaps with the second limiting plate 700, so that the overlapping portions of the second elastic member 800 and the second limiting plate 700 along the second direction Y come into contact with each other to form an elastic limiting structure.

[0050] In other embodiments, the projection of the second elastic member 800 on the second limiting plate 700 along the second direction Y completely falls into the second limiting plate 700, thereby maximizing the contact area between the second elastic member 800 and the second limiting plate 700, and further improving the stability of the elastic contact between the second elastic member 800 and the second limiting plate 700.

[0051] The second elastic element 800 can be at least one of rubber, silicone, and spring, and can be specifically set according to the actual situation.

[0052] like Figures 2 to 4 As shown, in some embodiments of this application, the second linear motor 200 further includes a second base 250, and the second guide rail 210 is disposed on the side of the second base 250 facing away from the first guide rail 110 along the third direction Z. A second photoelectric switch 600 is provided on the side of the second base 250 facing the second guide rail 210. The second photoelectric switch 600 is spaced apart from the second guide rail 210 and faces the second guide rail 210. The second photoelectric switch 600 detects whether the second mover 220 has moved to a designated position during the sliding process along the second guide rail 210. Thus, the second photoelectric switch 600, the second magnetic scale 230, and the second magnetic head 240 form a closed-loop detection and control of the movement position and movement distance of the second mover 220 on the second guide rail 210, thereby ensuring the accuracy and stability of the detection of the movement position and movement distance of the second mover 220 on the second guide rail 210.

[0053] The position of the second photoelectric switch 600 on the second base 250 can be set according to the actual situation.

[0054] In this embodiment, the second magnetic scale 230 is disposed on the side of the second base 250 facing the second guide rail 210, and the second magnetic scale 230 is spaced apart from the second guide rail 210 and the second mover 220 along the first direction X, so as to ensure the stability and smoothness of the second mover 220 during the movement along the second guide rail 210.

[0055] like Figure 1 and Figure 2As shown, in some embodiments of this application, the second linear motor 200 is provided with the first linear motor 100 at both ends along the second direction Y. It should be noted that the axes of the two sets of first linear motors 100 are parallel to each other and both are parallel to the first direction X. That is, the two sets of first linear motors 100 provide support and guidance for the second linear motor 200 to ensure the stability of the second linear motor 200. At the same time, it improves the stability of the second linear motor 200 driven by the two sets of first movers 120 along the first direction X, thereby improving the accuracy of position control of the first movers 120 and the second movers 220.
