The mover is used to carry the workpiece to transport the workpiece or move the workpiece to different workstations for processing.

[0003] In related technologies, to ensure stable transport of the moving part, it is typically fixed on a track. When the placement position of the workpiece carried by the moving part shifts, an external actuator needs to be adjusted accordingly to accurately clamp or process the workpiece. This adjustment of the external actuator increases the operational complexity of the system and affects processing efficiency. Utility Model Content

By setting the normal along the conveying direction, the setting width of the stator coil is not less than 1.25 times the setting width of the permanent magnet array, that is, the setting width of the stator coil is greater than the setting width of the permanent magnet array.

The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0024] In related technologies, conveyor lines typically include a mover and a stator. The mover usually carries the workpiece, and the stator and mover are magnetically coupled to enable the movement of the mover, thereby transferring the workpiece. The mover carries the workpiece to different workstations and cooperates with external mechanisms to perform operations such as loading / unloading and machining of the workpiece. To ensure stable transport, the mover is usually fixed on a track. However, due to factors such as mover position deviation and external loading deviation, the workpiece's placement position may deviate from the expected position. This necessitates secondary positioning by the external actuator to align the workpiece before loading / unloading and machining operations. Since each alignment consumes time, it reduces the workpiece's processing and conveying efficiency.

[0025] To solve the above problem, please refer to Figures 1 to 2 This application provides a magnetic drive conveying system 1, which includes a stator module 2 and a mover module 3. The stator module 2 and the mover module 3 are magnetically coupled to drive the movement of the mover module 3.

[0026] The stator module 2 includes a stator track 21 and a stator coil 22. The stator track 21 forms a placement cavity 211. The stator coil 22 is provided on the cavity wall 2111 and the cavity bottom 2112 of the placement cavity 211. The mover module 3 includes a mover body 31 and a permanent magnet array 32. At least part of the mover body 31 is located in the placement cavity 211. The permanent magnet array 32 is disposed on the mover body 31 and is disposed opposite to the stator coil 22. The stator coil 22 is coupled to the permanent magnet array 32 and drives the permanent magnet array 32 to move along the conveying direction X. The width of the stator coil 22 along the normal direction X is not less than 1.25 times the width of the permanent magnet array 32.

[0027] It is understood that, in this embodiment of the application, the stator coil 22 in the placement cavity 211 is energized to couple the stator coil 22 with the permanent magnet array 32, thereby enabling the stator body to move within the placement cavity 211.

[0028] That is, for the stator coil 22 located at the bottom of the cavity 2112, the magnitude and strength of the magnetic field of the stator coil 22 located at the bottom of the cavity 2112 can be adjusted by changing the magnitude of the current or changing the output power. In addition to driving the moving module 3 to move along the conveying direction X, the stator coil 22 located at the bottom of the cavity 2112 can also achieve position adjustment of the moving module 3 in the height direction Z. When there is a deviation between the placement height of the workpiece and the expected position, the output power of the stator coil 22 located at the bottom of the cavity 2112 can be changed to make the placement height of the workpiece consistent with the expected position. Furthermore, since the stator coil 22 located at the bottom of the cavity 2112 inherently has the property of driving the moving module 3 to move along the conveying direction X, during the process of driving the moving module 3 to move in the conveying direction X, the height adjustment of the moving module 3 during the movement can be achieved by changing the output power, so that when the moving module 3 reaches the process position, the workpiece can be placed in the expected position without additional adjustment time. That is, for the stator coil 22 located at the bottom of the cavity 2112, it can adjust the height of the moving module 3 so that the workpiece is in the expected position in the height direction Z without the need for secondary positioning by an external actuator. It can also change the height of the moving module 3 during the conveying process to ensure the workpiece is in the expected position without the need for secondary adjustment after the moving module 3 is in place. This improves the processing and conveying efficiency of the workpiece, and consequently improves the processing and conveying efficiency of the magnetic drive conveying system 1.

[0029] It should be noted that, for the moving module 3, the length direction of the moving module 3 can be understood as the conveying direction X as described in this embodiment; the width direction Y of the moving module 3 can be understood as the direction in which the cavity wall 2111 of the placement cavity 211 faces each other in this embodiment, or the direction in which the stator coil 22 and the permanent magnet array 32 face each other, or the left and right direction of the conveying direction X; the height direction Z of the moving module 3 can be understood as the "normal direction of the conveying direction X" as described in this embodiment, that is, the direction in which the bottom 2112 of the placement cavity 211 and the opening 2113 face each other.

[0030] Similarly, for the stator coil 22 located on the cavity wall 2111, the magnitude and strength of the magnetic field of the stator coil 22 located on the cavity wall 2111 can be adjusted by changing the magnitude of the current or changing the output power. In addition to driving the moving module 3 to move along the conveying direction X, the stator coil 22 located on the cavity wall 2111 can also adjust the position of the moving module 3 in the width direction Y. When there is a deviation between the placement position of the workpiece and the expected position, the output power of the stator coil 22 located on the cavity wall 2111 can be changed to make the placement position of the workpiece in the width direction Y consistent with the expected position. Furthermore, since the stator coil 22 located on the cavity wall 2111 inherently has the property of driving the moving module 3 to move along the conveying direction X, during the process of driving the moving module 3 to move in the conveying direction X, the left and right adjustments of the moving module 3 during the movement can be achieved by changing the output power, so that when the moving module 3 reaches the process position, the workpiece can be placed in the expected position without additional adjustment time. That is, for the stator coil 22 set on the cavity wall 2111, it can adjust the left and right position of the moving module 3 so that the workpiece is in the expected position in the width direction Y, without the need for secondary positioning by an external actuator. It can also change the left and right position of the moving module 3 during the conveying process of the moving module 3 so that the workpiece is in the expected position, without the need for secondary adjustment after the moving module 3 is in place. This improves the processing efficiency and conveying efficiency of the workpiece, and thus improves the processing efficiency and conveying efficiency of the magnetic drive conveying system 1.

[0031] It is understandable that when there is a deviation in the horizontal placement of the workpiece, that is, when the workpiece deviates from the expected position in both the conveying direction X and the width direction Y; or when there is a deviation in the spatial position of the workpiece, that is, when the workpiece deviates from the expected position in the conveying direction X, the width direction Y, and the height direction Z. In this case, the stator coil 22 located at the cavity bottom 2112 and the cavity wall 2111 can be adjusted to jointly complete the position change of the mover module 3.

[0032] Furthermore, along the normal direction X of the conveying direction, the width of the stator coil 22 is not less than 1.25 times the width of the permanent magnet array 32. That is, the maximum coverage profile of the stator coil 22 is greater than the coverage profile of the permanent magnet array 32. When the position of the mover module 3 is adjusted in the height direction Z or the width direction Y, the permanent magnet array 32 still has a good coupling relationship with the stator coil 22, and the permanent magnet array 32 is still coupled with the strong magnetic field emitted by the stator coil 22, so as to improve the conveying stability of the mover module 3 during the position change process, and thus improve the conveying stability of the mover module 3 during the conveying process.

[0033] It is understood that, in this embodiment, the normal direction of the conveying direction X, for the stator coil 22 located at the cavity bottom 2112, refers to the width direction Y. That is, for the stator coil 22 located at the cavity bottom 2112, the width of the stator coil 22 is not less than 1.25 times the width of the corresponding permanent magnet array 32. When the mover module 3 moves along the width direction Y, the stator coil 22 located at the cavity bottom 2112 can still have a large coupling area with the permanent magnet array 32, thereby providing a stable driving force for the conveying of the mover module 3. For the stator coil 22 located at the cavity wall 2111, the normal direction of the conveying direction X refers to the height direction Z. That is, for the stator coil 22 located at the cavity wall 2111, the width of the stator coil 22 is not less than 1.25 times the width of the corresponding permanent magnet array 32. When the moving module 3 moves along the height direction Z, the stator coil 22 located on the cavity wall 2111 can still have a large coupling area with the permanent magnet array 32, thereby providing a stable driving force for the transport of the moving module 3.

[0034] It is understood that the width of the permanent magnet array 32 at different positions on the mover body 31 may be different, and the width of the stator coil 22 corresponding to it will also change accordingly. This application embodiment does not limit this.

[0035] In summary, this embodiment of the application provides stator coils 22 in the cavity wall 2111 and cavity bottom 2112 of the placement cavity 211. By changing the current or power output of the stator coils 22 at different positions, the position of the mover body 31 in the placement cavity 211 is changed, thereby driving the position of the workpiece located on the mover module 3 to change. By actively adjusting the position of the mover module 3, the workpiece is placed in the expected position during the process, without the need for the external actuator to perform secondary positioning based on the workpiece position, thereby improving the processing efficiency and conveying efficiency of the magnetic drive conveying system 1.

[0036] Reference Figure 1 and Figure 2The stator track 21 includes a first profile 212, a second profile 213, and a third profile 214 connected in sequence. The first profile 212, the second profile 213, and the third profile 214 together form a placement cavity 211. The first profile 212 has an opening 2113 for the placement cavity 211. The stator coil 22 is disposed on the second profile 213 and the third profile 214.

[0037] In some embodiments, the first profile 212, the second profile 213, and the third profile 214 are integrally formed to facilitate the installation of the stator track 21, and the integral forming process can give the stator track 21 higher structural strength. In other embodiments, the first profile 212, the second profile 213, and the third profile 214 can be spliced ​​separately to form the stator track 21, so as to facilitate the replacement and maintenance of the stator track 21 components. The first profile 212 has an opening 2113 of a placement cavity 211. It can be understood that part of the mover body 31 is located inside the placement cavity 211, and the other part of the mover body 31 is located outside the placement cavity 211. The mover body 31 inside the placement cavity 211 is used to realize the conveying function of the mover module 3, and the mover body 31 outside the placement cavity 211 is used to carry the workpiece, realizing the carrying function of the mover module 3.

[0038] It is understood that the installation method of the stator track 21 is not limited in the embodiments of this application. After the installation of the stator track 21 is completed, in some embodiments, the opening direction of the cavity 2113 is downward, that is, the opening direction of the cavity 2113 is towards the ground, and the workpiece is set on the mover module 3 by means of hanging or the like; in other embodiments, the opening direction of the cavity 2113 is upward, that is, the opening direction of the cavity 2113 is towards the top of the ceiling, and the mover module 3 carries the workpiece to realize the transfer of the workpiece.

[0039] Reference Figures 1 to 4 The stator coil 22 includes a drive coil 221 and a traction coil 222. The drive coil 221 is disposed on the third profile 214, and multiple traction coils 222 are disposed at intervals on the second profile 213 along the height direction Z.

[0040] In this embodiment, the drive coil 221 provides power and levitation force to the moving module 3, so as to provide the main force for the movement of the moving module 3 along the conveying direction X; the traction coil 222 provides auxiliary power for the movement of the moving module 3 along the conveying direction X. This embodiment of the application expands the coverage area of ​​the traction coils 222 by arranging multiple traction coils 222 at intervals along the height of the second profile 213. On the one hand, this allows for better position adjustment of the moving module 3 along the height direction Z, thereby increasing the travel distance of the moving module 3 along the height direction Z. That is, even after the moving module 3 has changed position with a greater travel distance in the height direction Z, it can still receive the power provided by the traction coils 222 to support the movement of the moving module 3 along the conveying direction X. On the other hand, arranging more traction coils 222 along the height direction Z can increase the driving force on the moving module 3. When the moving module 3 has changed position with a greater travel distance in the height direction Z, the driving force of the drive coil 221 on the moving module 3 may decrease. This embodiment of the application compensates for the driving force provided by the drive coil 221 on the moving module 3 by arranging multiple traction coils 222, so that the moving module 3 still receives a relatively stable driving force, thereby achieving stable conveying of the moving module 3.

[0041] It is understood that in some embodiments, when the opening of the cavity 2113 faces downward, the workpiece is placed on the moving module 3 by means of suspension, etc., and the force between the drive coil 221 and the permanent magnet array 32 is an attractive force, which provides part of the levitation force for the moving module 3; when the opening of the cavity 2113 faces upward, the moving module 3 carries the workpiece, and the force between the drive coil 221 and the permanent magnet array 32 is a repulsive force, which provides part of the levitation force for the moving module 3.

[0042] In other embodiments, a permanent magnet may be provided in the drive coil 211. On the one hand, when the drive coil 211 is not energized, the permanent magnet can interact with the permanent magnet array to provide levitation force for the mover module 3. On the other hand, after the drive coil 211 is energized and energized, the drive coil 211 can have a stronger magnetic field to further improve the driving force provided to the mover module 3, thereby increasing the load of the mover module 3 and making the transport of the mover module 3 more stable.

[0043] Further, please refer to Figure 1 and Figure 2The stator module 2 also includes a guide groove 23, which is fixedly disposed on the first profile 212 and located within the placement cavity 211. The mover module 3 also includes a roller 33 that is tactilely connected to the guide groove 23 and is fixedly disposed on the mover body 31. In this embodiment, by providing the guide groove 23, the extension direction of the guide groove 23 is the same as the conveying direction X of the mover. The mover module 3 is provided with a roller 33 that is tactilely connected to the groove wall of the guide groove 23. The cooperation between the roller 33 and the guide groove 23 can limit the conveying direction X of the mover module 3, avoiding the mover module 3 from tipping over or tilting, or deviating from the conveying direction X due to different forces on the left and right sides. It can be understood that in this embodiment, the guide groove 23 is disposed within the placement cavity 211 to make reasonable use of the internal space of the placement cavity 211, improve the space utilization rate of the placement cavity 211, and achieve miniaturization of the magnetic drive conveying system 1.

[0044] In other embodiments, the guide groove 23 is fixedly disposed on the first profile 212 and located outside the placement cavity 211. The mover module 3 also includes a roller 33 that is tactilely connected to the guide groove 23. The mover body 31 includes a placement part 311 located inside the placement cavity 211 and a support part 312 located outside the placement cavity 211. The roller 33 is disposed on the support part 312, and the permanent magnet array 32 is disposed on the placement part 311.

[0045] In this embodiment, the guide groove 23 is disposed outside the placement cavity 211, which contains a placement part 311 and a permanent magnet array 32 located on the placement part 311. This achieves miniaturization of the placement cavity 211, and consequently, miniaturization of the stator track 21 and the stator module 2. By providing rollers 33 on the bearing part 312, the bearing part 312 can be limited by the guide groove 23 in addition to bearing the workpiece, thereby improving the stability of workpiece placement and the stability of workpiece conveying.

[0046] Further, please refer to Figure 1 and Figure 2 The roller 33 is used for rolling connection with the wall of the guide groove 23, and the width of the guide groove 23 is greater than the diameter of the roller 33. That is, the moving module 3 can move left and right, and the wall of the guide groove 23 and the roller 33 are rolled to limit the maximum stroke of the moving module 3 in the left and right directions. It can be understood that when the moving module 3 is at the maximum stroke of the left and right movement, the force on the left and right sides of the moving module 3 may be different because the distance between the permanent magnet array 32 on the left and right sides of the moving module 3 and the traction coil 222 is different. In this embodiment, by setting the width of the guide groove 23 to be greater than the diameter of the roller 33, the moving module 3 still receives a better guiding effect when it is at the maximum stroke position of the left and right movement, so as to reduce the side tilting or tilting of the moving module 3 caused by the different forces on the left and right sides, or reduce the adverse effects of the X-direction deviation of the moving module 3 caused by the different forces on the left and right sides.

[0047] In other embodiments, the roller 33 is used for rolling connection with the bottom of the guide groove 23, the depth of which is greater than the diameter of the roller 33. On one hand, the roller 33 can roll into the bottom of the guide groove 23, which supports the moving module 3, thereby reducing the levitation force requirements of the drive coil 221 and traction coil 222 on the moving module 3. When the moving module 3 carries a workpiece, the roller 33 directly contacts the bottom of the guide groove 23 to provide support, thus increasing the load-bearing capacity of the moving module 3. On the other hand, when the moving module 3 moves along the height direction Z, the roller 33 can engage with the guide groove 23 to achieve stable conveying of the moving module 3 along the height direction Z.

[0048] It is understood that in some embodiments, there can be multiple rollers 33, and the width of the guide groove 23 can be greater than the diameter of the roller 33, and the depth of the guide groove 23 can also be greater than the diameter of the roller 33.

[0049] Furthermore, please refer to Figures 3 to 4 The stator track 21 also includes a fourth profile 215 and a fifth profile 216. The third profile 214, the fourth profile 215 and the fifth profile 216 are connected in sequence, and the third profile 214, the fourth profile 215 and the fifth profile 216 surround to form a receiving cavity 217.

[0050] In some embodiments, the third profile 214, the fourth profile 215, and the fifth profile 216 are integrally formed to facilitate the installation of the stator rail 21, and the integral forming process can improve the structural strength of the stator rail 21. Further, the first profile 212, the second profile 213, the third profile 214, the fourth profile 215, and the fifth profile 216 can be integrally formed to facilitate the installation of the stator rail 21 and improve its structural strength. Alternatively, in other embodiments, the third profile 214, the fourth profile 215, and the fifth profile 216 can be individually spliced ​​to form the stator rail 21 to facilitate the disassembly and maintenance of the stator rail 21. Further, the first profile 212, the second profile 213, the third profile 214, the fourth profile 215, and the fifth profile 216 can all be independently spliced ​​to form the stator rail 21, facilitating the replacement and maintenance of the stator rail 21 components.

[0051] The magnetic drive conveying system 1 also includes a walking module 4, which is equipped with a magnet array 41. The walking module 4 is located in the receiving cavity 217, and the magnet array is arranged opposite to the drive coil 221.

[0052] It is understood that the stator track 21 has both a placement cavity 211 and a receiving cavity 217. The placement cavity 211 contains a moving module 3, and the receiving cavity 217 contains a traveling module 4. Both the moving module 3 and the traveling module 4 can transfer the workpiece. For example, in some embodiments, the moving module 3 is located above and the traveling module 4 is located below, that is, the opening 2113 of the placement cavity 211 faces the top of the ceiling, and the opening 2113 of the receiving cavity 217 faces the ground. The moving module 3 is used to carry the workpiece to realize the transfer of the workpiece; the workpiece can be suspended on the traveling module 4 to realize the transfer of the workpiece. Both the moving module 3 and the traveling module 4 are driven by the stator coil 22, which improves the transfer efficiency and speed of the workpiece, thereby improving the transmission efficiency of the magnetic drive conveying system 1.

[0053] Furthermore, since the placement cavity 211 is equipped with a drive coil 221 and a traction coil 222, and the traction coil 222 provides auxiliary power for the transport of the moving module 3, the transport speed of the moving module 3 and the transport speed of the traveling module 4 can be different. This allows the magnetic drive transport system 1 to have two different transport conditions, thereby improving the transport flexibility and versatility of the magnetic drive transport system 1. Moreover, the stator coil 22 can have multiple laying paths, so that the upper moving module 3 and the lower traveling module 4 have different transport paths.

[0054] In some embodiments, the stator module 2 further includes a guide rail 24, which is fixedly disposed on at least one of the fourth profile 215 and the fifth profile 216. The travel module 4 includes a guide wheel 42, which is engaged with the guide rail 24. Since the travel module 4 is disposed below, the guide wheel 42 provides support for the travel module 4 to increase its load capacity. That is, the loads of the mover module 3 and the travel module 4 can be different to improve the versatility of the magnetic drive conveyor system 1.
