Description

Commutating stator module and magnetic drive conveyor system Technical Field

[0001] This application relates to the field of conveying equipment technology, and in particular to a commutator stator module and a magnetic drive conveying system. Background Technology

[0002] A magnetically driven transport line typically includes magnetically coupled stator modules and mover modules. Multiple stator modules are combined to form a stator transport line. The stator coils of the stator transport line are periodically energized to generate a traveling wave magnetic field. The traveling wave magnetic field interacts with the permanent magnet array of the mover module to drive the mover module to move along a predetermined route. When the mover module is carrying a load, it can move the object on it, thereby realizing the transport of the object.

[0003] When the moving part of an existing magnetic drive conveyor changes its conveying path, a commutating stator module is needed to change the conveying direction. However, existing commutating stator modules are large and require a significant amount of space. Summary of the Invention

When the limiting member is in the clearance position, the mover module can enter and exit; when the limiting member is in the guiding position, it limits and guides the mover module. A clearance space is formed between the stator body and the base, and the driving member is located within the clearance space.

[0006] Furthermore, the clearance space includes a plurality of sub-clearance spaces disposed around the stator body and the base, and a plurality of limiting components are provided around the stator body, with the plurality of driving components respectively located within the plurality of sub-clearance spaces.

[0007] Furthermore, both the stator body and the base are square structures. The clearance space includes four sub-clearance spaces located between the stator body and the base at the corner positions. The limiting components are respectively provided on the four sides of the stator body, and the four driving components are respectively located in the four sub-clearance spaces.

[0008] Furthermore, the limiting component includes a guide member disposed on the base, the guide member cooperating with the limiting member to guide the limiting member to rise and fall.

[0009] Furthermore, the thickness of the limiting member is greater than or equal to 4 mm and less than or equal to 10 mm.

[0010] Furthermore, the limiting component includes a photoelectric sensor and a light-shielding member. The photoelectric sensor is disposed on the base, and the light-shielding member is disposed on the limiting member. The photoelectric sensor detects the position of the limiting member by cooperating with the light-shielding member.

[0011] Furthermore, the limiting member includes a first limiting member and a second limiting member. The first limiting member is connected to the driving member, and the second limiting member is assembled at the end of the first limiting member away from the driving member. The second limiting member includes a joint portion protruding toward the stator body. The stator body includes a clearance groove, and the joint portion is located in the clearance groove.

[0012] Furthermore, the joint between the first limiting member and the stator body is offset from the joint between the second limiting member and the stator body.

[0013] Furthermore, the second limiting member includes a protrusion that protrudes in a direction away from the stator body.

[0014] Furthermore, multiple sets of the limiting components are respectively provided on the same side of the stator body, and the limiting component only includes a second limiting component directly connected to the drive component. The second limiting component includes a joint portion protruding towards the stator body, and the stator body includes a clearance groove that cooperates with the joint portion.

[0015] Furthermore, the stator body is provided with multiple sets of limiting components on its periphery, the driving components are all cylinders, the base is provided with a solenoid valve and multiple air pipe connectors, the multiple air pipe connectors are arranged in two rows, one row of air pipe connectors is connected to the first air outlet of the solenoid valve and the first air inlet of the cylinder through an air pipe, and the other row of air pipe connectors is connected to the second air outlet of the solenoid valve and the second air inlet of the cylinder through an air pipe.

[0016] Furthermore, the commutation stator module also includes a driver located within the clearance space, the driver being positioned at a corner of the clearance space, and the base having a through cavity communicating with the clearance space at the corner position.

[0017] One aspect of this application provides a magnetic drive conveying system, the magnetic drive conveying system comprising: a stator conveying line including a linear stator module and a commutated stator module as described above, the linear stator module and the commutated stator module being spliced ​​together, the linear stator module including a linear armature winding; and a mover module including a permanent magnet assembly, the permanent magnet assembly being used for magnetic coupling with the commutated armature winding or the linear armature winding.

[0018] This application provides driving forces in different directions to the mover module through the first and second commutation windings. Combined with the lifting and lowering of the limiting component, the mover module can be reversed on the stator conveyor line. When reversing the mover module, only the limiting component needs to be driven to lift and lower. No additional external mechanism or external track is required to change the conveying direction of the mover module. This is beneficial for miniaturizing the magnetic drive conveyor device and can also quickly change the conveying direction of the mover module, making the magnetic drive conveyor system more efficient. Furthermore, since the driving components are all set in the clearance space formed between the stator body and the base, the volume of the commutation stator module can be further reduced, which is more conducive to miniaturizing the magnetic drive conveyor device.

[0028] Referring to Figures 1 and 5, this embodiment of the present invention provides a magnetic drive conveying system. The system includes a stator conveyor line and a mover module 70. The stator conveyor line includes a linear stator module and a commutated stator module 100, which are spliced ​​together. The linear stator module includes a linear armature winding. The mover module 70 is magnetically coupled to the stator conveyor line, enabling the stator conveyor line to drive the mover module.

[0029] Specifically, the mover module 70 can be magnetically coupled to the linear stator module or the commutating stator module 100, so that the linear stator module can be used to drive the mover module to perform linear motion, which can include linear motion and curvilinear motion, and the commutating stator module 100 can be used to realize the direction conversion of the mover module 70 on the magnetic drive conveyor line.

[0030] During transport, the mover module 70 moves linearly on the linear stator module, and its direction is changed on the commutating stator module 100. This eliminates the need for external connecting tracks, allowing the mover module 70 to change its transport path. This method does not occupy additional space, facilitating the miniaturization of the magnetic drive transport system. Furthermore, the process of the mover module 70 moving to the commutating stator module 100 does not consume additional time, thus improving transport efficiency.

[0031] The commutating stator module 100 includes a base 10, a stator body 20, a commutating armature winding 30, and a limiting assembly 40. The stator body 20 is fixed to the base 10, and the commutating armature winding 30 is disposed on the stator body 20. The commutating armature winding 30 includes a first commutating winding 31 extending along a first direction and a second commutating winding 32 extending along a second direction. The first commutating winding 31 is used to drive the mover module 70 to move along the first direction, and the second commutating winding 32 is used to drive the mover module to move along the second direction. Specifically, the first commutating winding 31 is magnetically coupled to the first permanent magnet array 721 to drive the mover module 70 to move along the first direction, and the second commutating winding 32 is magnetically coupled to the second permanent magnet array 722 to drive the mover module 70 to move along the second direction.

[0032] A limiting component 40 is disposed on the base 10. The limiting component 40 includes a limiting member 41 and a driving member 42. The driving member 42 drives the limiting member 41 to rise and fall, allowing the limiting member 41 to switch between a clearance position and a guiding position. When the limiting member 41 is in the clearance position, it allows the moving part module 70 to enter and exit. When the limiting member 41 is in the guiding position, it limits and guides the moving part module. The driving member 42 can be in the form of a cylinder, lead screw, linear motor, robot, etc., or it can be a combination of multiple cylinders, lead screws, etc., which is not limited here. In the illustrated embodiment, the driving member 42 is a cylinder.

[0033] A clearance space 80 is formed between the stator body 20 and the base 10, and all drive members 42 are located within the clearance space 80. This means that the clearance space 80 between the stator body 20 and the base 10 can be fully utilized to accommodate the drive members 42, eliminating the need to place the drive members 42 externally, thus reducing the overall space occupied by the commutation stator module 100. In one embodiment, the drive member 42 is fixed to the stator body 20. In another embodiment, the drive member 42 is fixed to the base 10. In yet another embodiment, the drive member 42 is fixedly connected to both the stator body 20 and the base 10.

[0034] In this embodiment, the first commutation winding 31 and the second commutation winding 32 provide driving forces in different directions to the mover module 70. Combined with the lifting and lowering of the limiting member 41, the mover module can be reversed on the stator conveyor line. When reversing the mover module 70, only the limiting member 41 needs to be driven to lift and lower. No additional external mechanism or external track is required to change the conveying direction of the mover module. This is beneficial for miniaturizing the magnetic drive conveyor system and can also quickly change the conveying direction of the mover module 70, making the magnetic drive conveyor system more efficient. Furthermore, since the driving members 42 are all located within the clearance space 80 formed between the stator body 20 and the base 10, the driving members 42 are not placed on the outside, which can further reduce the volume of the commutation stator module 100 and is more conducive to miniaturizing the magnetic drive conveyor device 100.

[0035] Referring to Figure 5, the mover module 70 serves as a load-bearing component, used to stably support and transport the product. In the illustrated embodiment, the mover module 70 includes a mover base 71, a permanent magnet assembly 72, and a guide assembly 73. Both the permanent magnet assembly 72 and the guide assembly 73 are disposed on the mover base 71. The permanent magnet assembly 72 is used for magnetic coupling with the commutating armature winding or the linear armature winding. The permanent magnet assembly 72 includes a first permanent magnet array 721 arranged along a first direction and a second permanent magnet array 722 arranged along a second direction, with the first and second directions forming an angle. In one embodiment, the first and second directions are perpendicular to each other, but this is not a limitation.

[0036] Referring to Figure 2, the limiting assembly 40 includes a first limiting assembly 49 and a second limiting assembly 48. The first limiting assembly 49 includes a first direction limiting member 491 and a first driving member 492 for driving the first direction limiting member 491 to move up and down. The first direction limiting member 491 extends along a first direction and is used to limit and guide the moving part module to move along the first direction. The second limiting assembly 48 includes a second direction limiting member 481 and a second driving member 482 for driving the second direction limiting member 481 to move up and down. The second direction limiting member 481 extends along a second direction and is used to limit and guide the moving part module to move along the second direction.

[0037] Understandably, when the mover module 70 needs to move along the first direction from another stator module on the magnetic drive conveyor line to the commutating stator module 100, the second drive member 482 can drive the second direction limiting member 481 to descend, so that the second direction limiting member 481 is spaced from the mover module, allowing the second direction limiting member 481 to avoid the movement trajectory of the mover module. Furthermore, the first drive member 492 can drive the first direction limiting member 491 to rise until it contacts the mover module, and the first commutating winding 31 can drive the mover module to move along the first direction, using the first direction limiting member 491 as the mover... The module provides a limiting guide to guide the moving module to move smoothly along the first direction onto the commutating stator module 100. When the moving module needs to commutate to move along the second direction, the second driving member 482 first drives the second direction limiting member 481 to rise to contact the moving module, and then the first driving member 492 drives the first direction limiting member 491 to fall to a distance from the moving module. The second commutating winding 32 drives the moving module to move along the second direction. The second direction limiting member 481 provides a limiting guide for the moving module to move along the second direction onto other linear stator modules.

[0038] The clearance space 80 includes multiple sub-clearance spaces 81 disposed around the stator body 20 and the base 10. Multiple limiting components 40 are provided around the stator body 20, and multiple driving components 42 are respectively disposed within the multiple sub-clearance spaces 81. The sub-clearance spaces 81 are used to accommodate the driving components 42, and the size of the sub-clearance spaces 81 matches the size of the driving components 42. The multiple sub-clearance spaces 81 are spaced apart, and the multiple driving components 42 can be disposed close to each other within the multiple sub-clearance spaces 81.

[0039] In the illustrated embodiment, both the stator body 20 and the base 10 are square structures. The clearance space 80 includes four sub-clearance spaces 81 located between the stator body 20 and the base 10 at corner positions. Limiting components 40 are respectively provided on the four sides of the stator body 20, and four driving components 42 are respectively located within the four sub-clearance spaces 81. In this way, each driving component 42 can be placed close to its corresponding sub-clearance space 81, resulting in a compact structure and convenient assembly.

[0040] In one embodiment, the drive member 42 is disposed in the sub-avoidance space 81 formed between the portion of the stator body 20 not covered by the first commutation winding 31 and the second commutation winding 32 and the base 10, and the driver 50 is disposed in the avoidance space formed between the portion of the stator body 20 covered by the first commutation winding 31 and the second commutation winding 32 and the base 10. In this way, the avoidance space 80 is fully utilized to accommodate the drive member 42 and the driver 50, which is beneficial to improving space utilization.

[0041] It should be noted that the telescopic component of the drive member 42 is always within the clearance space 80 during the lifting and lowering process of the drive limiting member 41. In one embodiment, the drive member 42 is a cylinder, and the piston of the cylinder is always within the clearance space 80 during the telescopic stroke, which will not be listed here.

[0042] In one embodiment, the stator body 20 has the same shape and size as the base 10, and the limiting member 41 is located within the clearance space 80 and passes through the stator body 20. In another embodiment, the stator body 20 has the same shape as the base 10, and the size of the base 10 is larger than the size of the stator body 20, and the limiting member 41 is located outside the clearance space 80. These are just some examples and are not limited to.

[0043] Each side of the stator body 20 is provided with one or more sets of limiting components 40. In one embodiment, each side of the stator body 20 is provided with two sets of limiting components 40, each set of limiting components 40 including one driving member 42 and one limiting member 41, each driving member 42 being located within a corresponding sub-clearance space 81, and each sub-clearance space 81 having two driving members 42. In another embodiment, each side of the stator body 20 is provided with one set of limiting components 40, each set of limiting components 40 including one driving member 42 and one limiting member 41, each driving member 42 being disposed within a corresponding sub-clearance space 81, and each sub-clearance space 81 having one driving member 42. These are just some examples and are not limited to the examples described above.

[0044] Referring to Figure 1, the limiting component 40 includes a guide member 43 disposed on the base 10. The guide member 43 cooperates with the limiting member 41 to guide the limiting member 41 to rise and fall. The cooperation between the guide member 43 and the limiting member 41 prevents the limiting member 41 from tilting during rising and falling, thus providing more reliable limiting and guiding of the moving part module. Specifically, the guide member 43 is fixed to the edge of the base 10 and includes a guide rail. The limiting member 41 includes a slider. The slider, in cooperation with the guide rail, guides the movement of the limiting member 41 between the unsupported position and the guided position.

[0045] In one embodiment, the guide member 43 is configured as a guide rail structure extending in the vertical direction, and the limiting member 41 is configured as a slider structure cooperating with the guide rail structure. In another embodiment, the guide member 43 is configured as a guide post extending in the vertical direction, and the limiting member 41 is slidably sleeved on the guide post. These are just some examples and are not limited to the examples described above.

[0046] The thickness of the limiting member 41 is greater than or equal to 4 mm and less than or equal to 10 mm. This allows the limiting member 41 to be thinner and lighter. When the limiting member 41 is tilted, the force exerted by the limiting member 41 on the guide member 43 is smaller, which allows the guide member 43 to better limit and guide the limiting member 41, thus improving the positional accuracy of the limiting member 41.

[0047] In some embodiments, the thickness of the limiting member 41 can be 4 mm, 5 mm, 6 mm, 7 mm, 8 mm, 9 mm, 10 mm, or any value between any two adjacent values ​​mentioned above.

[0048] The limiting component 40 includes a photoelectric sensor 19 and a light-shielding member 18. The photoelectric sensor 19 is disposed on the base 10, and the light-shielding member 18 is disposed on the limiting component 41. The photoelectric sensor 19 detects the position of the limiting component 41 by cooperating with the light-shielding member 18. The light-shielding member 18 rises or falls with the limiting component 41. When the limiting component 41 rises or falls to its final position, the relative position between the light-shielding member 18 and the photoelectric sensor 19 changes. At this time, the photoelectric sensor 19 can obtain the position signal of the limiting component 41 based on the sensed change in light and send the position signal to the controller of the magnetic drive conveyor system. The controller can issue control commands to the moving module based on the received position signal.

[0049] Please refer to Figures 3 and 5. In order to solve the problem of reduced positioning accuracy caused by collision when the moving part module crosses the seam between the commutation stator module 100 and other linear stator modules, the limiting member 41 includes a first limiting member 411 and a second limiting member 412. The first limiting member 411 is connected to the driving member 42, and the second limiting member 412 is assembled at the end of the first limiting member 411 away from the driving member 42. The second limiting member 412 includes a joint portion 413 protruding toward the stator body 20. The stator body 20 includes a relief groove 24, and the joint portion 413 is located in the relief groove 24. Because the second limiting member 412 includes a connecting portion 413 protruding toward the stator body 20, and the stator body 20 includes a relief groove 24, with the connecting portion 413 located within the relief groove 24, the seam between the second limiting member 412 and the stator body 20 is offset from the seam between the commutating stator module 100 and other linear stator modules. When the moving module 70 passes through the seam between the commutating stator module 100 and other linear stator modules, the roller 74 of the moving module 70 has already crossed the seam between the second limiting member 412 and the stator body 20. Thus, the moving module 70 will not be affected by crossing the seam. The gap between the commutating stator module 100 and other linear stator modules leads to a decrease in positioning accuracy. However, since the gap between the second limiting member 412 and the stator body 20 is located within the commutating stator module 100, in other words, the gap between the second limiting member 412 and the stator body 20 is within the detection range of the position sensor of the commutating stator module 100, the mover module 70 will not cause a decrease in the position detection accuracy of the mover module when it crosses the gap between the second limiting member 412 and the stator body 20. This is beneficial to improving the accuracy and reliability of the position detection of the mover module.

[0050] The joint between the first limiting member 411 and the stator body 20 is misaligned with the joint between the second limiting member 412 and the stator body 20. In other words, the joint between the second limiting member 412 and the stator body 20 is necessarily misaligned with the joint between the commutating stator module 100 and other linear stator modules. When the moving module 70 passes through the joint between the commutating stator module 100 and other linear stator modules, the roller 74 of the moving module 70 has already crossed the joint between the second limiting member 412 and the stator body 20. Therefore, the positioning accuracy of the moving module 70 will not decrease due to crossing the joint between the commutating stator module 100 and other linear stator modules.

[0051] The second limiting member 412 includes a protrusion 417 protruding in a direction away from the stator body 20. Correspondingly, the linear stator module adjacent to the commutating stator module 100 is provided with a groove (not shown), and the protrusion 417 is located in the groove. By providing the protrusion 417, the joint between the second limiting member 412 and the linear stator module is misaligned with the joint between the commutating stator module 100 and the linear stator module. This also solves the problem of reduced positioning accuracy caused by collision when the mover module crosses the joint between the commutating stator module 100 and other linear stator modules.

[0052] Referring to Figure 6, in this embodiment, when the moving module 70 passes through the commutating stator module 100, the limiting member 41 switches to the guide position to guide and limit the moving module 70. At this time, the joint 413 abuts against the side of the moving module 70. When multiple limiting members 41 are provided on the same side of the stator body 20, the end faces of the multiple joints 413 that abut against the moving module 70 are coplanar, thus enabling more stable guidance of the moving module 70.

[0053] Referring to Figure 7, in this embodiment, when the moving module 70 passes through the commutating stator module 100, the limiting member 41 switches to the guide position to guide and limit the moving module 70. At this time, the joint 413 is located above the moving module 70 to limit the moving module 70, which can reduce the vibration generated by the moving module 70 when passing through the commutating stator module 100, making the conveying more stable.

[0054] Multiple sets of limiting components 40 are provided on the same side of the stator body 20, and the limiting member 41 only includes a second limiting member 412 directly connected to the driving member 42. The second limiting member 412 includes a connecting portion 413 protruding towards the stator body 20. The stator body 20 includes a relief groove 24, and the connecting portion 413 is located within the relief groove 24. Since multiple sets of limiting components 40 are provided on the same side of the stator body 20, and the second limiting member 412 is directly connected to the driving member 42, that is, the multiple second limiting members 412 on the same side of the stator body 20 are driven individually by multiple driving members 42. Thus, the second limiting member 412 is less likely to tilt and has better stability. In some embodiments, the limiting components 40 can be set to 2 sets, 3 sets, 4 sets, etc., and are not limited thereto.

[0055] Please refer to Figure 4. Multiple sets of limiting components 40 are provided around the stator body 20. All driving components 42 are cylinders. The base 10 is equipped with a solenoid valve 61 and multiple air pipe connectors 62, arranged in two rows. One exhaust pipe connector 62 is connected to the first air outlet 611 of the solenoid valve 61 and the first air inlet 421 of the cylinder via an air pipe. The other exhaust pipe connector 62 is connected to the second air outlet 612 of the solenoid valve 61 and the second air inlet 422 of the cylinder via an air pipe. In other words, one air path is used to raise the limiting component 41, and the other air path is used to lower the limiting component 41. This makes the air path connections clearer, reduces the likelihood of errors during connection, and facilitates maintenance personnel in case of air path failure.

[0056] In one embodiment, when air enters through the first air inlet 421 of the cylinder, the limiting member 41 is driven to rise, and when air enters through the second air inlet 422 of the cylinder, the limiting member 41 is driven to fall. In another embodiment, when air enters through the first air inlet 421 of the cylinder, the limiting member 41 is driven to fall, and when air enters through the second air inlet 422 of the cylinder, the limiting member 41 is driven to rise.

[0057] The commutator stator module 100 also includes a driver 50 located within a clearance space 80. The driver 50 is positioned at a corner of the clearance space 80, and the base 10 has a through cavity 15 at the corner that communicates with the clearance space 80. The through cavity 15 facilitates the insertion of cables into the driver 50. The driver 50 is used to energize the first commutator winding 31 and the second commutator winding 32, and to receive the real-time position sensing signal of the mover module from the position sensor. It then sends the relevant signal to an external controller. In other words, the driver 50 is used to control and detect the position of the mover module. The external controller transmits control signals to the driver, enabling the driver to drive the mover module to move along a preset input pattern.

[0058] The above description is merely a preferred embodiment of this application and is not intended to limit this application. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the scope of protection of this application.
