Description

Technical Field

[0001] This invention relates to the field of motor technology, and in particular to a dual-modular transverse flux linear motor. Background Technology

[0002] A linear motor is a transmission device that converts electrical energy into linear motion mechanical energy without any intermediate conversion mechanism. A linear motor can be viewed as being formed by radially splitting the stator and rotor of a rotary motor and then unfolding them into a planar shape. A three-phase symmetrical sinusoidal current is injected into the coil windings of the linear motor, generating a traveling wave magnetic field. This magnetic field interacts with the static magnetic field generated by the permanent magnet, producing the thrust of the linear motor. Under the action of this thrust, the linear motor moves in a straight line.

[0003] Many existing linear motors use transverse flux linear motors, which offer advantages such as high torque density, flexible design, electromagnetic load decoupling, and convenient control. However, the output force and stroke of many existing transverse flux linear motors are fixed, making it impossible to adapt them to changing application scenarios. For example, Chinese patent application CN119921513A discloses a high-stability linear motor, comprising: a motor base, a stator and a slide rail mounted on the motor base, a slide block slidably mounted on the motor base, a mover and a slider mounted at the bottom of the slide block, the stator and mover being matched, the slider slidably mounted on the slide rail, an encoder mounted on one side of the slide block, a cover plate on the top of the motor base, and open sides of the motor base; air filter mechanisms are mounted on both sides of the motor base, including filter components and flow guiding components. This invention uses only one stator and one mover, employing a fixed matching mode, which can only provide one output force and stroke, failing to meet the needs of different application scenarios.

[0004] Therefore, developing a transverse flux linear motor whose output force and stroke can be adjusted according to the needs of different application scenarios has become an urgent problem to be solved. Summary of the Invention

[0005] This invention provides a dual-modular transverse flux linear motor, which solves the problem that the output force and stroke of existing linear motors are fixed and cannot be changed according to the application scenario.

[0006] To achieve the above objectives, the present invention provides a dual-modular transverse flux linear motor, comprising:

[0007] A motor base, wherein a mounting groove is formed on one side of the motor base;

[0008] Two guide rails are mounted on one side of the motor base where the mounting groove is formed, and are respectively located on both sides of the mounting groove;

[0009] A winding module assembly, the winding module assembly including at least one winding module with independent magnetic flux path, one end of the winding module being detachably installed in the mounting slot;

[0010] A magnetic pole module assembly includes at least one magnetic pole module with an independent magnetic flux path. The magnetic pole module includes an iron yoke and two permanent magnets with opposite polarities. The iron yoke is slidably connected to two guide rails. A clearance cavity is formed on the iron yoke corresponding to the winding module, allowing the winding module to pass through. The two permanent magnets are located in the clearance cavity and on opposite sides of the winding module.

[0011] In one embodiment of this application, the winding module includes three identical double-sided coils, namely a first double-sided coil, a second double-sided coil, and a third double-sided coil;

[0012] The first double-sided coil, the second double-sided coil, and the third double-sided coil each include a first vertical rod, a first horizontal plate, a second vertical rod opposite to the first vertical rod, a second horizontal plate opposite to the first horizontal plate, and windings wound around the first vertical rod, the second vertical rod, the first horizontal plate, and the second horizontal plate; the first horizontal plate and the second horizontal plate are located on the same side of the first vertical rod and the second vertical rod, and are both connected to the first vertical rod and the second vertical rod, with the first horizontal plate located near the motor base;

[0013] The first vertical rod of the first double-sided coil, the second vertical rod of the second double-sided coil, the first vertical rod of the third double-sided coil, the second vertical rod of the first double-sided coil, the first vertical rod of the second double-sided coil, and the second vertical rod of the third double-sided coil are arranged alternately along the length direction of the mounting groove; the first horizontal plate and the second horizontal plate of the first double-sided coil are respectively flush with the first horizontal plate and the second horizontal plate of the second double-sided coil, the first horizontal plate of the third double-sided coil is located between the first horizontal plate and the second horizontal plate of the first double-sided coil, and the second horizontal plate of the third double-sided coil is located on the side of the first horizontal plate of the first double-sided coil away from the second horizontal plate of the first double-sided coil.

[0014] In one embodiment of this application, the first double-sided coil, the second double-sided coil, and the third double-sided coil are connected by a filling resin.

[0015] In one embodiment of this application, a limiting structure is further included that can be detachably installed on the motor base. The limiting structure is provided on both sides of each winding module, and two adjacent limiting structures clamp one winding module.

[0016] In one embodiment of this application, the mounting groove has seat locking grooves on both sides of the bottom of the groove. The seat locking grooves extend through both ends of the motor base along the length direction of the motor base. Each seat locking groove has elastic clamping pieces on both sides. The ends of the elastic clamping pieces extend to the ends of the seat locking grooves. Each limiting structure has a limiting insertion protrusion corresponding to each seat locking groove. The limiting insertion protrusion is inserted into the locking cavity formed between the elastic clamping pieces.

[0017] In one embodiment of this application, the elastic clamping piece includes a vertical section and an arc-shaped curved section connecting the vertical section and the groove wall of the seat clamping groove. The vertical sections of the two elastic clamping pieces are arranged in parallel, and the arc-shaped curved sections of the two elastic clamping pieces are curved toward each other.

[0018] In one embodiment of this application, the elastic clamping piece is provided with a dividing groove, which divides the elastic clamping piece into several clamping parts.

[0019] In one embodiment of this application, the limiting structure includes a first limiting block and a second limiting block. The first limiting block has a block locking groove. One end of the first limiting block abuts against one of the winding modules adjacent to the limiting structure, and the other end is penetrated by the block locking groove. One end of the second limiting block is slidably inserted into the block locking groove, and the other end extends out of the block locking groove and abuts against another winding module adjacent to the limiting structure. The second limiting block is fixed to the first limiting block by a block fastening screw, and the limiting insertion protrusion is provided on the first limiting block.

[0020] In one embodiment of this application, the yoke includes two vertical yoke plates, one horizontal yoke plate, two yoke extension plates, and two sliders. The two vertical yoke plates are arranged opposite to each other. One end of the two vertical yoke plates away from the motor base is connected by the horizontal yoke plate, and the other end is connected to the two yoke extension plates respectively. The vertical yoke plates and the horizontal yoke plate form the clearance cavity. The yoke extension plates extend from the vertical yoke plates in a direction away from the clearance cavity. The two sliders are respectively mounted on the two yoke extension plates and are slidably connected to the two guide rails respectively. The sliders are located on the side of the yoke extension plate opposite to the horizontal yoke plate.

[0021] In one embodiment of this application, the yoke extension plate is provided with a yoke mounting groove that passes through the yoke vertical plate, and the permanent magnet extends a plug plate into the yoke mounting groove on the side facing the yoke vertical plate. The plug plate is fixed to the yoke extension plate by plate fastening screws.

[0022] The above-described solution of the present invention has the following beneficial effects:

[0023] This invention, by setting a magnetic pole module comprising an iron yoke and two permanent magnets with opposite poles, provides a clearance cavity on the iron yoke to allow the winding module to pass through, and installs the two permanent magnets within the clearance cavity. Under the combined action of the iron yoke and the two permanent magnets, a transverse magnetic flux path is generated within the iron yoke as shown in the figure. The magnetic pole module travels along the vertical cross-section of the iron yoke, thus the magnetic flux path of each magnetic pole module is closed within itself, and the magnetic flux paths of each magnetic pole module unit are completely independent. Furthermore, because the magnetic pole module is detachably mounted on the motor base, therefore... The number of magnetic pole modules can be freely selected. Since the linear motor uses winding modules with completely independent magnetic flux paths, and the winding modules can be detachably installed in the sliding groove of the motor base, the number of winding modules installed on the motor base can also be freely selected. This invention adopts a dual modular structure of winding modules and magnetic pole modules with completely independent magnetic flux paths, which allows for flexible selection of the number and combination of winding modules and magnetic pole modules to meet the needs of different application scenarios. The output force and stroke of the linear motor can be changed accordingly, making it highly applicable.

[0024] Other beneficial effects of the present invention will be described in detail in the following detailed description section. Attached Figure Description

[0042] Please see Figures 1 to 12 The present invention provides a dual-modular transverse flux linear motor, comprising a motor base 10, two guide rails 20, a winding module assembly, and a magnetic pole module assembly.

[0043] like Figure 1 As shown, a mounting groove 11 is formed on one side of the motor base 10; two guide rails 20 are mounted on the side of the motor base 10 where the mounting groove 11 is formed, and are respectively located on both sides of the mounting groove 11; the winding module assembly includes at least one winding module 30 with an independent magnetic flux path, and the winding module 30 is detachably installed in the mounting groove 11. The magnetic pole module assembly includes at least one magnetic pole module 60, such as... Figure 9 As shown, the magnetic pole module 60 includes a yoke 61 and two permanent magnets 62 with opposite polarities. The yoke 61 is slidably connected to two guide rails 20. A clearance cavity 615 is formed on the yoke 61 corresponding to the winding module 30, allowing the winding module 30 to pass through. The two permanent magnets 62 are located in the clearance cavity 615 and on opposite sides of the winding module 30. The winding module assembly generates a traveling wave magnetic field when energized, and the magnetic pole module assembly generates a main pole magnetic field when energized. The interaction of the two magnetic fields produces an electromagnetic thrust that drives the linear motor.

[0044] This invention, by setting the magnetic pole module 60 to include an iron yoke 61 and two permanent magnets 62 with opposite magnetic poles, provides a clearance cavity 615 on the iron yoke 61 to allow the winding module 30 to pass through, and installs the two permanent magnets 62 inside the clearance cavity 615. Under the combined action of the iron yoke 61 and the two permanent magnets 62, a magnetic field is generated within the iron yoke 61 as... Figure 11As shown in the diagram, the magnetic pole module 60 travels along the vertical cross-section of the yoke 61 within the yoke 61. Therefore, the magnetic flux path of each magnetic pole module 60 can be closed within itself, and the magnetic flux paths of each magnetic pole module 60 unit are completely independent. Thus, the number of magnetic pole modules 60 can be freely selected. Furthermore, since the linear motor uses winding modules 30 with completely independent magnetic flux paths, and since the winding modules 30 can be detachably installed in the groove of the motor base, the number of winding modules 30 installed on the motor base 10 can also be freely selected.

[0045] This invention employs a dual-modular structure with completely independent magnetic flux paths for both winding modules 30 and magnetic pole modules 60. The number and combination of winding modules 30 and magnetic pole modules 60 can be flexibly selected to adapt the output force and stroke of the linear motor to different application scenarios, thus improving applicability. For example, to increase the stroke path of the linear motor, the number of winding modules 30 can be increased; to increase the output force, the number of magnetic pole modules 60 can be increased; and to increase both the stroke and output force, both magnetic pole modules 60 and winding modules 30 can be increased simultaneously. This invention features a simple structure, fast dynamic response, and can be used in a range of high-end precision industrial systems such as semiconductor processing platforms, intelligent multi-dimensional system motion platforms, dispensing machines, and microelectronics / optoelectronics packaging platforms.

[0046] In one embodiment of this application, such as Figure 5 and Figure 6 The winding module 30 includes three identical double-sided coils, namely the first double-sided coil 40a, the second double-sided coil 40b, and the third double-sided coil 40c.

[0047] The first double-sided coil 40a, the second double-sided coil 40b, and the third double-sided coil 40c each include a first vertical rod 41, a first horizontal plate 43, a second vertical rod 42 opposite to the first vertical rod 41, a second horizontal plate 44 opposite to the first horizontal plate 43, and windings (not shown in the figure) wound on the first vertical rod 41, the second vertical rod 42, the first horizontal plate 43, and the second horizontal plate 44; the first horizontal plate 43 and the second horizontal plate 44 are located on the same side of the first vertical rod 41 and the second vertical rod 42, and are both connected to the first vertical rod 41 and the second vertical rod 42; the first horizontal plate 43 is located near the motor base 10.

[0048] The first vertical rod 41 of the first double-sided coil 40a, the second vertical rod 42 of the second double-sided coil 40b, the first vertical rod 41 of the third double-sided coil 40c, the second vertical rod 42 of the first double-sided coil 40a, the first vertical rod 41 of the second double-sided coil 40b, and the second vertical rod 42 of the third double-sided coil 40c are arranged alternately along the length of the mounting groove 11. The first horizontal plate 43 and the second horizontal plate 44 of the first double-sided coil 40a are respectively flush with the first horizontal plate 43 and the second horizontal plate 44 of the second double-sided coil 40b. The first horizontal plate 43 of the third double-sided coil 40c is located between the first horizontal plate 43 and the second horizontal plate 44 of the first double-sided coil 40a. The second horizontal plate 44 of the third double-sided coil 40c is located on the side of the first horizontal plate 43 of the first double-sided coil 40a away from the second horizontal plate 44 of the first double-sided coil 40a.

[0049] The first double-sided coil 40a, the second double-sided coil 40b, and the third double-sided coil 40c are connected by a filling resin.

[0050] By arranging the double-sided coils as described above, the winding module 30, assembled from the first double-sided coil 40a, the second double-sided coil 40b, and the third double-sided coil 40c, can be guaranteed to have an independent magnetic flux circuit. Since each double-sided coil has an identical structure, it can be mass-produced without individual processing; the three double-sided coils can be directly assembled to form the winding module 30.

[0051] In other alternative embodiments, microfluidic channels may be provided within the filling resin. These microfluidic channels increase the contact area between the winding module 30 and the air, thereby enhancing the heat dissipation function of the winding module 30.

[0052] like Figure 7 As shown, the dual-modular transverse flux linear motor also includes limiting structures 50. Each winding module 30 has a limiting structure 50 on both sides. The limiting structures 50 are detachably mounted on the motor base 10, and two adjacent limiting structures 50 clamp the winding module 30 located between the two limiting structures 50. The limiting structures 50 can ensure the stability of the winding module 30 on the motor base 10 and prevent the winding module 30 from moving in the mounting groove 11 or falling off the motor base 10 due to external forces.

[0053] Furthermore, such as Figure 2 As shown, mounting groove 11 has mounting slots 12 on both sides of its bottom. The mounting slots 12 extend through both ends of the motor base 10 along its length. Each mounting slot 12 has elastic clamping pieces 13 on both sides, with both ends of the elastic clamping pieces 13 extending to both ends of the mounting slot 12. Figure 8As shown, each limiting structure 50 is provided with a limiting insertion protrusion 512 corresponding to each seat locking groove 12. The limiting insertion protrusion 512 is inserted into the locking cavity formed between the elastic clamping pieces 13. By the elastic clamping of the limiting insertion protrusion 512 by the two elastic clamping pieces 13, the limiting structure 50 is fastened to the motor base 10.

[0054] Optional, such as Figure 3 As shown, the elastic clamping piece 13 includes a vertical section 131 and an arc-shaped curved section 132 connecting the vertical section 131 and the groove wall of the seat locking groove 12. The vertical sections 131 of the two elastic clamping pieces 13 are arranged in parallel, and the arc-shaped curved sections 132 of the two elastic clamping pieces 13 are curved towards each other. The arc-shaped curved section 132 is used to provide elastic clamping force, and the vertical section 131 is used to provide clamping of the limiting insertion protrusion 512 and can provide a large contact area for the insertion protrusion. Under the combined action of the elastic clamping force of the arc-shaped curved section 132 and the large clamping area of ​​the vertical section 131 on the limiting insertion protrusion 512, a stable clamping of the limiting structure 50 can be achieved.

[0055] Optional, such as Figure 4 As shown, the elastic clamping piece 13 is provided with a dividing groove 133, which divides the elastic clamping piece 13 into several clamping parts 134. When the limiting insertion protrusion 512 of the limiting structure 50 is inserted between the two elastic clamping pieces 13, if the elastic clamping piece 13 is not divided, the elastic clamping piece 13 will generate great resistance to the limiting insertion protrusion 512 inserted into the seat locking groove 12, and it will be very difficult to insert the limiting insertion protrusion 512 of the limiting structure 50 into the locking cavity between the two elastic clamping pieces 13. However, dividing the elastic clamping piece into several clamping parts 134 through the dividing groove 133 can reduce the resistance of the elastic clamping piece 13 to the limiting insertion protrusion 512, making it easier for the limiting insertion protrusion 512 to be inserted between the elastic clamping pieces 13.

[0056] Furthermore, such as Figure 8As shown, the limiting structure 50 includes a first limiting block 51 and a second limiting block 52. The first limiting block 51 has a block locking groove 511. One end of the first limiting block 51 abuts against a winding module 30 of one adjacent limiting structure 50, and the other end is penetrated by the block locking groove 511. One end of the second limiting block 52 is slidably inserted into the block locking groove 511, and the other end extends out of the block locking groove 511 and abuts against another winding module 30 of another adjacent limiting structure 50, so that the second limiting block 52 can slide relative to the first limiting block 51 to adjust the length of the limiting structure 50 and realize the adjustment of the distance between the winding modules 30. The second limiting block 52 is fixed to the first limiting block 51 by a block fastening screw 53. The block fastening screw 53 passes through the second limiting block 52, extends into the block locking groove 511, and then presses against the first limiting block 51. The block fastening screw 53 and the first limiting block 51 are threadedly connected. To adjust the length of the limiting structure 50, first loosen the block fastening screw 53 away from the second limiting block 52, then pull the second limiting block 52 relative to the first limiting block 51. This adjusts the length of the limiting structure 50. When the limiting structure 50 reaches the desired length, tighten the block fastening screw 53 to re-secure the second limiting block 52 to the first limiting block 51. This design of the limiting structure 50 allows for adjustment of the distance between the winding modules 30, enabling the winding module combination to meet the requirements of multi-size magnetic pole modules 60. When the application scenario changes, but the required output force does not change significantly, the size of the permanent magnet 62 in the magnetic pole module 60 can be adjusted to meet the needs of fine-tuning the linear motor's output force. For example, when increasing the size of the permanent magnet 62 to slightly increase the linear motor's output force, the size of the entire magnetic pole module 60 will also increase due to the larger permanent magnet 62. The magnetic field coverage of the enlarged permanent magnet 62 is wider, so the winding modules 30 do not need to be distributed too densely on the motor base 10. The distance between the winding modules 30 can be adjusted accordingly using the limiting structure 50, reducing the number of winding modules 30 and lowering costs. When decreasing the size of the permanent magnet 62 in the magnetic pole module 60 to slightly decrease the linear motor's output force, the size of the entire magnetic pole module 60 will also decrease due to the smaller permanent magnet 62. The magnetic field coverage of the smaller permanent magnet 62 is narrower, requiring the winding modules 30 to be distributed more densely on the motor base 10. In this case, the distance between the winding modules 30 can be reduced accordingly by shortening the length of the limiting structure 50 to ensure the linear motor's output force. In summary, the adjustable length limiting structure 50 enables the winding module combination to match magnetic pole modules 60 of different sizes to slightly increase or decrease the output force of the linear motor, thereby improving the applicability of the winding module combination.

[0057] In other feasible embodiments, the limiting structure 50 can be removed, and the coil winding 20 can be fixed in the mounting groove 11 by the friction between itself and the groove wall of the mounting groove 11.

[0058] In one embodiment of this application, such as Figure 9 As shown, the yoke 61 includes two vertical yoke plates 611, one horizontal yoke plate 612, two yoke extension plates 613, and two sliders 614. The two vertical yoke plates 611 are arranged opposite to each other. One end of the two vertical yoke plates 611 away from the motor base 10 is connected through the horizontal yoke plate 612, and the other end is connected to the two yoke extension plates 613 respectively. The vertical yoke plates 611 and the horizontal yoke plate 612 form a relief cavity 615. The yoke extension plates 613 extend from the vertical yoke plates 611 in a direction away from the relief cavity 615. The two sliders 614 are respectively installed on the two yoke extension plates 613 and are slidably connected to the two guide rails 20 respectively. The sliders 614 are located on the side of the yoke extension plate 613 away from the horizontal yoke plate 612.

[0059] Furthermore, such as Figure 10 As shown, the yoke extension plate 613 has a yoke mounting groove 6131 that passes through the yoke vertical plate 611. The permanent magnet 62 has an insertion plate 621 extending into the yoke mounting groove 6131 from the side facing the yoke vertical plate 611. The insertion plate 621 is fixed to the yoke extension plate 613 by plate fastening screws 63. The plate fastening screws 63 pass through the yoke extension plate 613 from the side of the yoke extension plate 613 near the yoke horizontal plate 612 and extend into the yoke mounting groove 6131, pressing against the insertion plate 621 to fasten the insertion plate 621 to the yoke extension plate 613, thereby fixing the entire permanent magnet 62 to the yoke 61. The plate fastening screws 63 are threadedly connected to the yoke extension plate 613. The setting of the iron yoke mounting groove 6131 in the iron yoke extension plate 613 and the insertion plate 621 on the permanent magnet 62 can realize the adjustment of the distance between the two permanent magnets 62, and realize the fine adjustment of the output force of the linear motor. When it is necessary to adjust the distance between the two permanent magnets 62, loosen the plate fastening screw 63, and then move the permanent magnet 62 relative to the iron yoke extension plate 613. When the distance between the two permanent magnets 62 is adjusted to the required distance, tighten the plate fastening screw 63 to fasten the permanent magnet 62 to the iron yoke 61. When the distance between the two permanent magnets 62 decreases, the magnetic flux path generated by the radial winding module 30 of the magnetic path of the permanent magnet 62 will move closer together, thereby increasing the magnetic flux that interacts between the permanent magnet 62 and the winding module 30, which can increase the output force of the linear motor. When the distance between the two permanent magnets 62 increases, the magnetic flux path of the permanent magnet 62 will move away from the magnetic flux path of the winding module 30, thereby reducing the magnetic flux that interacts between the permanent magnet 62 and the winding module 30, which can reduce the output force of the linear motor.

[0060] In one embodiment of this application, the dual-modular transverse flux linear motor further includes a connecting belt 70, such as... Figure 1 As shown, two adjacent magnetic pole modules 60 are detachably connected by a connecting strap 70, and the connecting strap 70 is detachably linked to the extension plate of the yoke 61 of the two magnetic pole modules 60 by a locking structure. Figure 10 and Figure 12 As shown, the locking structure includes a locking protrusion 71 on the connecting strap 70 and a locking hole 6132 on the yoke extension plate. The locking protrusion 71 is inserted into the locking hole 6132. After the number of magnetic pole modules 60 is determined according to the force required for the application and installed on the motor base 10, vibration will occur when the linear motor is working. If the magnetic pole modules 60 are not connected by the connecting strap 70, the vibration will cause the magnetic pole modules 60 to separate, affecting the travel distance. Connecting the magnetic pole modules 60 with the connecting strap 70 solves this problem.

[0061] The above description represents the preferred embodiments of the present invention. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principles of the present invention, and these improvements and modifications should also be considered within the scope of protection of the present invention.
