[0009] Furthermore, the conveyor line includes multiple stator modules arranged along the conveying direction and a track structure disposed on the stator modules. The support structure includes support wheels, and the track structure is supported below the support wheels. The track structure includes a first guide rail disposed on a first side of the multiple stator modules and a second guide rail disposed on a second side of the multiple stator modules. The guiding structure includes a first guide member that guides and cooperates with the first guide rail and a second guide member that guides and cooperates with the second guide rail. The first guide member is a guide wheel, and the guide wheel guides and cooperates with the side wall of the first guide rail. And / or, the second guide member is a guide shaft, and a guide groove is provided on the second guide rail, and the guide shaft is inserted into the guide groove.

[0010] Furthermore, the mover body includes a permanent magnet array and a readable medium. A coil and a read head are arranged along the conveying direction on the conveying line. The coil and the read head are spaced apart in the width direction of the conveying line. The coil is arranged correspondingly to the permanent magnet array and magnetically coupled. The read head is arranged correspondingly to the readable medium and inductively coupled.

[0011] Furthermore, the mover body includes a permanent magnet array, which forms a readable medium. A coil and a read head are arranged along the conveying direction on the conveyor line. The read head is located inside the coil, or the read head and the coil are spaced apart in the height direction of the conveyor line and the orthographic projection of the read head is located within the orthographic projection of the coil. The coil is magnetically coupled to the permanent magnet array, and the read head is inductively coupled to the readable medium.

[0012] Furthermore, the conveyor line includes a straight section and an arc section spliced ​​with the straight section, and the reader includes a first reader section disposed on the straight section and a second reader section disposed on the arc section, with the ends of the first reader section and the ends of the second reader section spaced apart in the width direction of the conveyor line.

[0013] Furthermore, the conveyor line includes a straight section and an arc section spliced ​​with the straight section.

[0016] By applying the technical solution of this utility model, the moving body is magnetically coupled to the conveyor line and can move relative to the conveyor line along the conveying direction. The moving body is equipped with a support structure and a guide structure.

The guide structure guides and cooperates with the conveyor line to enable the moving body to move stably along the conveying direction. That is, during the movement of the moving body, the support structure and the guide structure are in direct contact with the conveyor line to support and guide the moving body. The support structure and guide structure are mounted on the mover body via a rotating frame. When the mover module passes through an arc or curve segment on the conveyor line, the rotating frame rotates, thereby moving the guide structure and support structure mounted on it to a position adapted to the conveyor line. This ensures that the movement direction of the support structure and guide structure is close to the conveying direction of the conveyor line, reducing the squeezing and frictional forces between the support structure, guide structure, and conveyor line. When the mover module moves from the arc or curve segment to a straight segment on the conveyor line, the rotating frame is reset to its initial state by the reset structure, i.e., reset to a position where the support structure and guide structure are adapted to the straight segment of the conveyor line, improving the smoothness of the mover module's movement. Therefore, the technical solution of this application can effectively solve the problem of squeezing and friction between the mover module and the stator module when the mover module passes through an arc or curve segment in the related technology.

It should be noted that similar reference numerals and letters in the following drawings denote similar items; therefore, once an item is defined in one drawing, it need not be further discussed in subsequent drawings.

[0036] like Figures 1 to 3 As shown, this application provides a conveying system. An embodiment of the conveying system includes a conveyor line 10 and a moving part module, wherein the moving part module includes a moving part body 20, a rotating frame 30, a support structure 40, a guide structure 50, and a reset structure 60. The conveyor line 10 extends along a conveying direction a; the moving part body 20 is magnetically coupled to the conveyor line 10 and is movable relative to the conveyor line 10 along the conveying direction a; the rotating frame 30 is rotatably mounted on the moving part body 20; the support structure 40 is mounted on the rotating frame 30 and supports the conveyor line 10; the guide structure 50 is mounted on the rotating frame 30 and guides the conveyor line 10; the reset structure 60 is disposed between the rotating frame 30 and the moving part body 20 to maintain the rotating frame 30 in its initial state.

[0037] Applying the technical solution of this embodiment, the moving body 20 is magnetically coupled to the conveyor line 10 and can move relative to the conveyor line 10 along the conveying direction a. The moving body 20 is equipped with a support structure 40 and a guide structure 50. The support structure 40 supports and cooperates with the conveyor line 10 so that the moving body 20 can be stably magnetically coupled to the conveyor line 10. The guide structure 50 guides and cooperates with the conveyor line 10 so that the moving body 20 can move stably along the conveying direction a. That is, during the movement of the moving body 20, the support structure 40 and the guide structure 50 are in direct contact with the conveyor line 10 to support and guide the moving body 20. The support structure 40 and guide structure 50 are mounted on the moving body 20 via the rotating frame 30. When the moving body 20 passes through the arc segment 14 or curved segment on the conveyor line 10, the rotating frame 30 can rotate, thereby driving the guide structure 50 and support structure 40 mounted on it to move to a position that matches the conveyor line 10. This ensures that the movement direction of the support structure 40 and guide structure 50 is close to the conveying direction of the conveyor line 10, thereby reducing the squeezing and frictional forces between the support structure 40 and guide structure 50 and the conveyor line 10. When the moving body 20 moves to the position of the straight segment 13 on the conveyor line 10 after passing through the arc segment 14 or curved segment, the rotating frame 30 will be reset to its initial state under the action of the reset structure 60. That is, the rotating frame 30 is reset to the position where the support structure 40 and guide structure 50 match the straight segment of the conveyor line 10, improving the smoothness of the movement of the moving body 20. Therefore, the technical solution of this embodiment can effectively solve the problem of compression and friction between the moving module and the stator module when the moving module passes through the arc segment or curve segment in the related technology.

[0038] It is understandable that during the movement of the moving body 20 along the conveyor line 10, for the straight segment 13, since the movement direction of the support structure 40 is parallel to the conveying direction a of the moving body 20, there is relatively little friction between the support structure 40 and the conveyor line 10. For the curved segment 14, since the support structure in the related technology is fixedly set on the moving body, there is a large angle between the movement direction of the support structure and the conveying direction of the moving body. Therefore, during the process of the moving body being conveyed along the curved segment of the conveyor line under the limiting action of the guide structure, there will be a large friction between the support structure and the conveyor line, which will accelerate the wear of the support structure and the conveyor line, thereby reducing the service life of the support structure and the conveyor line. In this embodiment, the rotating frame 30 is set on the moving body 20, and the support structure 40 and the guide structure 50 are both set on the rotating frame 30. The guide structure 50 is used to guide and cooperate with the conveyor line 10 to change the posture of the rotating frame 30, thereby changing the movement direction of the support structure 40. When the moving body 20 is conveyed along the straight segment 13, since the conveying direction a of the moving body 20 is constant during the conveying process of the straight segment 13, the guide structure 50 and the conveyor line 10 are guided and cooperated. Under the limitation of the guide structure 50, the rotating frame 30 makes the movement direction of the support structure 40 parallel to the conveying direction a of the moving body 20, so as to reduce the friction between the support structure 40 and the conveyor line 10. When the moving body 20 moves along the arc segment 14, the guide structure 50 changes the posture of the rotating frame 30 in real time, so that the movement direction of the support structure 40 is approximately the same as the conveying direction a of the moving body 20. That is, in this embodiment of the application, by setting the guide structure 50 and the conveyor line 10 to cooperate, the guide structure 50 drives the rotating frame 30 to rotate to reduce the angle between the movement direction of the support structure 40 and the conveying direction a, thereby reducing the friction between the support structure 40 and the conveyor line 10, and thus improving the service life of the support structure 40 and the conveyor line 10.

[0039] like Figure 2As shown, the rotating frame 30 includes a connecting part 31 and a placement part 32 adjacent to both sides of the connecting part 31. The connecting part 31 is rotatably engaged with the moving body 20. The support structure 40 and the guide structure 50 are both disposed in the placement part 32. The reset structure 60 includes a first elastic member 61 and a second elastic member 62. The first elastic member 61 and the second elastic member 62 are disposed on both sides of the placement part 32 along the conveying direction a. The two ends of the first elastic member 61 are respectively connected to the placement part 32 and the moving body 20, and the two ends of the second elastic member 62 are respectively connected to the placement part 32 and the moving body 20. The first elastic element 61 and the second elastic element 62 are respectively disposed on both sides of the placement part 32 along the conveying direction a. Even if the placement part 32 deflects under the action of the arc segment 14 or the curved segment, when the moving body 20 moves to the straight segment 13, the placement part 32 quickly returns to the middle position under the action of the first elastic element 61 and the second elastic element 62, ensuring the reset effect and avoiding deviation between the movement direction of the support structure 40 and the conveying direction a of the moving module, so as to improve the stability of the moving module before and after the bend and reduce the friction between the support structure 40 and the conveying line 10. That is, under the action of no external force, the movement direction of the support structure 40 and the guide structure 50 disposed on the placement part 32 is the same as the conveying direction, improving the stability of the moving module in the straight segment 13 and the arc segment 14.

[0040] like Figure 2 As shown, there are two placement parts 32, which are symmetrically arranged with respect to the connecting part 31. Each placement part 32 is provided with a support structure 40, a guide structure 50 and a reset structure 60, thereby achieving support and guidance on both sides of the conveyor line 10 and improving the stability and reliability of the moving body 20 during movement.

[0041] It should be noted that the phrase "the two placement parts 32 are symmetrically arranged relative to the connecting part 31" refers to the two placement parts 32 being symmetrically arranged with respect to the center plane of the connecting part 31 extending along the conveying direction a. Correspondingly, the support structure 40, guide structure 50, and reset structure 60 provided on the two placement parts 32 are also symmetrically arranged with respect to the center plane of the connecting part 31 extending along the conveying direction a.

[0042] like Figure 2 As shown, the first elastic element 61 and the second elastic element 62 are symmetrically arranged with respect to the center plane of the placement part 32. Here, "center plane of the placement part 32" refers to the center plane of the placement part 32 perpendicular to the conveying direction a. By symmetrically arranging the first elastic element 61 and the second elastic element 62 with respect to the center plane of the placement part 32, the same type of elastic element can be used as the first elastic element 61 and the second elastic element 62, thereby applying the same or nearly the same amount of force to the placement part 32 and improving the accuracy of the placement part 32's repositioning.

[0043] like Figure 2 As shown, a cavity 21 is provided on the mover body 20 corresponding to the placement portion 32, and at least part of the placement portion 32 is disposed within the cavity 21. Both the first elastic member 61 and the second elastic member 62 are disposed within the cavity 21. By extending at least part of the placement portion 32, along with the support structure 40 and guide structure 50 disposed thereon, into the cavity 21, the overall thickness of the mover module can be reduced, thereby reducing the overall size of the conveying system. Furthermore, placing both the first elastic member 61 and the second elastic member 62 within the cavity 21 protects the first elastic member 61 and the second elastic member 62, improving their service life and reset effect.

[0044] like Figure 2 and Figure 3 As shown, the conveyor line 10 includes multiple stator modules 11 arranged along the conveying direction a and a track structure 12 disposed on the stator modules 11. The support structure 40 includes a support wheel 41, and the track structure 12 is supported below the support wheel 41. The track structure 12 includes a first guide rail 121 disposed on a first side of the multiple stator modules 11 and a second guide rail 122 disposed on a second side of the multiple stator modules 11. The guide structure 50 includes a first guide member 51 that guides and cooperates with the first guide rail 121 and a second guide member 52 that guides and cooperates with the second guide rail 122. The first guide member 51 is a guide wheel, and the guide wheel guides and cooperates with the side wall of the first guide rail 121. Through the support and cooperation between the first guide rail 121 and the support wheel 41, the first guide rail 121 and the first guide member 51, the second guide rail 122 and the support wheel 41, and the second guide rail 122 and the second guide member 52, both sides of the mover module can be supported and guided, making the movement of the mover body 20 smoother and more stable. The first guide member 51 is a guide wheel, which cooperates with the side wall of the first guide rail 121 to guide and reduce the friction between the first guide member 51 and the first guide rail 121 while achieving guidance, thereby improving the smoothness of the movement of the mover body 20 and the service life of the first guide member 51 and the first guide rail 121.

[0045] like Figure 2 As shown, in this embodiment, the second guide member 52 is also a guide wheel, and the guide wheel is guided and engaged with the side wall of the second guide rail 122.

[0046] Of course, in other feasible implementations, the second guide member can be a guide shaft. Specifically, the second guide member is a guide shaft, and a guide groove is provided on the second guide rail, with the guide shaft inserted into the guide groove.

[0047] In specific implementation, the first guide member and the second guide member can have the same structure. For example, both the first guide member and the second guide member can be guide wheels, or both the first guide member and the second guide member can be guide shafts. The first guide member and the second guide member can also have different structures. For example, one of the first guide member and the second guide member can be a guide wheel, and the other of the first guide member and the second guide member can be a guide shaft.

[0048] Specifically, such as Figure 2 As shown, a moving module includes a moving body 20 and two rotating frames 30. Each rotating frame 30 has two placement parts 32. Each placement part 32 is provided with a support wheel 41 and two guide wheels to improve the stability of the moving module movement.

[0049] like Figure 1 and Figure 4 As shown, the moving body 20 includes a permanent magnet array 22 and a readable medium 23. A coil 15 and a read head 16 are arranged along the conveying direction a on the conveyor line 10. The coil 15 and read head 16 are spaced apart in the width direction of the conveyor line 10. The coil 15 is correspondingly arranged and magnetically coupled to the permanent magnet array 22, and the read head 16 is correspondingly arranged and inductively coupled to the readable medium 23. The corresponding arrangement and magnetic coupling of the coil 15 and the permanent magnet array 22 enables the moving body 20 to move along the conveying direction a; the corresponding arrangement and inductive coupling of the read head 16 and the readable medium 23 enables the position detection of the moving body 20, thereby facilitating precise control of the movement of the moving body 20.

[0050] It should be noted that, Figures 4 to 7 The readable medium 23 marked in the figure is not the readable medium 23 itself, but the projection of the readable medium 23 on the transport line 10. By showing the projection of the readable medium 23 on the transport line 10, the relative position of the readable medium 23 and the read head 16 can be clearly seen.

[0051] In some embodiments, the reader 16 is a strip structure. By directly arranging the reader 16 and the coil 15 side by side in the width direction b of the conveyor line 10, the assembly difficulty of the conveyor line 10 can be simplified.

[0052] In some embodiments, such as Figure 2 and Figure 5As shown, the mover body 20 includes a permanent magnet array 22, a portion of which forms a readable medium 23. A coil 15 and a read head 16 are arranged along the conveying direction a on the conveyor line 10. The read head 16 is disposed within the coil 15, or the read head 16 and the coil 15 are spaced apart in the height direction of the conveyor line 10, with the orthographic projection of the read head 16 located within the orthographic projection of the coil 15. The coil 15 is magnetically coupled to the permanent magnet array 22, and the read head 16 is inductively coupled to the readable medium 23. The read head 16 has a strip-shaped structure. By directly placing the read head 16 within the coil 15, or by having the read head 16 and the coil 15 spaced apart in the height direction of the conveyor line 10 with the orthographic projection of the read head 16 located within the orthographic projection of the coil 15, the width of the conveyor line 10 can be reduced, thereby lowering the overall cost of the conveyor line 10.

[0053] Specifically, when the reading head 16 is placed inside the coil 15, the reading head 16 may include a plurality of magnetic induction elements arranged along the conveying direction a. When the reading head 16 is directly placed inside the coil 15, the thickness of the conveying line 10 can be reduced. When the reading head 16 and the coil 15 are spaced apart in the height direction of the conveying line 10, the assembly cost of the conveying line 10 can be reduced.

[0054] like Figure 6 As shown, the conveyor line 10 includes a straight segment 13 and an arc segment 14 spliced ​​with the straight segment 13. The read head 16 includes a first read head segment 161 disposed on the straight segment 13 and a second read head segment 162 disposed on the arc segment 14. The ends of the first read head segment 161 and the ends of the second read head segment 162 are spaced apart in the width direction of the conveyor line 10. It can be understood that when the mover body 20 moves onto the arc segment 14, the motion trajectory formed by the projection of the readable medium 23 onto the arc segment 14 may change due to factors such as the length of the mover and the turning radius of the arc segment 14. The projection trajectory of the readable medium 23 is misaligned with the arc length of the arc segment 14, that is, the center of the circle corresponding to the projection trajectory of the readable medium 23 is misaligned with the center of the circle corresponding to the arc segment 14. Furthermore, in this embodiment, by spacing the ends of the first reading head segment 161 and the second reading head segment 162 along the width of the conveyor line 10, on the one hand, the center of the circle corresponding to the trajectory of the second reading head segment 162 coincides with the center of the circle corresponding to the arc segment 14, so that the second reading head segment 162 has a shorter setting length and a more standard setting structure, thereby reducing the setting cost of the second reading head segment 162; on the other hand, by reducing the distance between the second reading head segment 162 and the readable medium 23, the setting position of the second reading head segment 162 is closer to the projection position of the readable medium 23 on the arc segment 14, thereby improving the position detection accuracy of the arc segment 14 on the moving body 20.

[0055] like Figure 7As shown, the conveyor line 10 includes a straight section 13 and an arc section 14 spliced ​​with the straight section 13. The reader 16 includes a third reader section 163 disposed on the straight section 13 and a fourth reader section 164 and a fifth reader section 165 disposed on the arc section 14. The third reader section 163 and the fourth reader section 164 are continuously disposed, and the fifth reader section 165 and the fourth reader section 164 are spaced apart in the width direction of the conveyor line 10. When the moving body 20 moves along the straight segment 13, the movement trajectory of each point on the moving body 20 is consistent with the extension direction of the straight segment 13; when the moving body moves to the arc segment 14, the movement trajectory of each point on the moving body 20 is not completely consistent with the extension direction of the arc segment 14. At this time, the originally facing readable medium 23 and read head 16 will be misaligned. In this embodiment, by setting a fourth read head segment 164 and a fifth read head segment 165 spaced apart on the arc segment 14, when the moving body 20 is in a position on the arc segment 14 close to the straight segment 13, the fourth read head segment 164... 64 can accurately sense the readable medium 23; when the moving body 20 is located on the arc segment 14 relatively far from the straight segment 13, the readable medium 23 is far from the fourth reading head segment 164, which will weaken the sensing ability between the two. At this time, the readable medium 23 can be sensed by the fifth reading head segment 165, thereby ensuring that when the moving body 20 moves on the arc segment 14, the readable medium 23 can be guaranteed to be within the better sensing range of at least one of the fourth reading head segment 164 and the fifth reading head segment 165, thereby improving the accuracy of position detection of the moving body 20.

[0056] Preferably, the accuracy of the fifth reading head segment 165 is lower than that of the fourth reading head segment 164. The fourth reading head segment 164, as the primary detection element, has higher detection accuracy to better detect the position of the moving part 20; the fifth reading head segment 165, as a secondary detection element with lower detection accuracy, is also used to detect the position of the moving part 20. After acquiring the detection data from the fourth and fifth reading head segments 164, the controller combines the detection data from the fifth reading head segment 165 with the detection data from the fourth reading head segment 164 using a compensation algorithm to more accurately determine the current position of the moving part 20. This achieves better detection accuracy for the moving part 20 while also reducing the setup cost of the conveying system.

[0057] like Figure 5As shown, the conveyor line 10 includes a straight section 13 and an arc section 14 spliced ​​with the straight section 13. The reading head 16 includes a sixth reading head section 166 disposed on the straight section 13 and a seventh reading head section 167 disposed on the arc section 14. The seventh reading head section 167 and the sixth reading head section 166 are continuously disposed. The readable medium 23 includes a first medium 231 and a second medium 232 disposed at intervals in the width direction of the moving body 20. The first medium 231 and the second medium 232 are disposed on both sides of the seventh reading head section 167. When the moving body 20 moves along the straight segment 13, all points on the moving body 20 move along the extension direction of the straight segment 13. When the moving body moves to the arc segment 14, the movement trajectory of each point on the moving body 20 is not completely consistent with the extension direction of the arc segment 14. At this time, the originally facing readable medium 23 and the read head 16 will be misaligned. By setting a first medium 231 and a second medium 232 spaced apart along the width direction on the moving body 20, and the seventh read head segment 167 is located between the first medium 231 and the second medium 232, when the moving body 20 moves along the arc segment 14, at least one of the first medium 231 and the second medium 232 is within the better sensing range of the seventh read head segment 167, thereby improving the accuracy of position detection of the moving body 20.

[0058] In addition, the first medium 231 and the second medium 232 can also be disposed on both sides of the sixth reading head segment 166. By also distributing the first medium 231 and the second medium 232 at intervals on the straight segment 13, the sixth reading head segment 166 and the first medium 231 and the second medium 232 can be sensed well, thereby improving the accuracy of position detection of the moving body 20.

[0059] It should be noted that, in Figures 4 to 7 In the figure, the dotted lines inside the conveyor line 10 show the outline of the coil 15, which includes multiple coil bodies 151 arranged along the extension direction of the conveyor line 10 (only one is shown in the figure for illustration). The dashed lines inside the conveyor line 10 show the reading head 16, which has a continuous structure.

[0060] In the description of this utility model, it should be understood that "multiple" means two or more. Directional terms such as "front, back, up, down, left, right," "horizontal, vertical, perpendicular, horizontal," and "top, bottom" indicate directions or positional relationships based on the directions or positional relationships shown in the accompanying drawings. These terms are used solely for the convenience of describing this utility model and simplifying the description. Unless otherwise stated, these directional terms do not 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 limiting the scope of protection of this utility model. The directional terms "inner" and "outer" refer to the inner or outer contours relative to the outline of each component itself.

[0061] For ease of description, spatial relative terms such as "above," "on top of," "on the upper surface of," "above," etc., are used herein to describe the spatial positional relationship of a device or feature as shown in the figures to other devices or features. It should be understood that spatial relative terms are intended to encompass different orientations in use or operation beyond the orientation of the device as described in the figures. For example, if the device in the figures were inverted, a device described as "above" or "on top of" other devices or structures would subsequently be positioned as "below" or "under" other devices or structures. Thus, the exemplary term "above" can include both "above" and "below." The device may also be positioned in other different ways (rotated 90 degrees or in other orientations), and the spatial relative descriptions used herein will be interpreted accordingly.

[0062] Furthermore, it should be noted that the use of terms such as "first" and "second" to define components is merely for the purpose of distinguishing the corresponding components. Unless otherwise stated, the above terms have no special meaning and therefore cannot be construed as limiting the scope of protection of this utility model.

[0063] The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
