[0002] A linear motor is a kind of transmission device that can convert electric energy into linear mechanical energy without any intermediate conversion mechanism.

For those skilled in the art, the specific meaning of the above terms in the present application can be understood according to the specific circumstances.
[0042] Please refer to Figures 1 to 12 A double modular transverse flux linear motor is described in the embodiments of the present application, which comprises a motor base 10, two guide rails 20, a winding module combination and a magnetic pole module combination.
[0043] As Figure 1 shown, one side of the motor base 10 is formed with a mounting groove 11; the two guide rails 20 are mounted on the side of the motor base 10 formed with the mounting groove 11 and are located on both sides of the mounting groove 11, respectively; the winding module combination comprises at least one winding module 30 with independent magnetic flux path, and the winding module 30 is detachably mounted in the mounting groove 11. The magnetic pole module combination comprises at least one magnetic pole module 60, as Figure 9 shown, the magnetic pole module 60 comprises an iron yoke 61 and two permanent magnets 62 with opposite polarities, the iron yoke 61 is slidably connected to the two guide rails 20, and the iron yoke 61 is formed with a clearance cavity 615 allowing the winding module 30 to pass through, and the two permanent magnets 62 are located in the clearance cavity 615 and on opposite sides of the winding module 30. Among them, the winding module combination generates a traveling wave magnetic field when energized, the magnetic pole module combination generates a main pole magnetic field when excited, and the two magnetic fields interact to generate an electromagnetic thrust to drive the linear motor to move.
[0044] The present application sets the magnetic pole module 60 to comprise an iron yoke 61 and two permanent magnets 62 with opposite magnetic poles, sets the clearance cavity 615 allowing the winding module 30 to pass through on the iron yoke 61, and installs the two permanent magnets 62 in the clearance cavity 615, under the joint action of the iron yoke 61 and the two permanent magnets 62, the iron yoke 61 can generate a magnetic field as Figure 11The transverse magnetic flux path is shown, the magnetic pole module 60 travels in the vertical direction of the iron yoke 61 along the cross section of the iron yoke 61, so that the magnetic flux path of each magnetic pole module 60 can be closed in its own internal, the magnetic flux path of each magnetic pole module 60 unit is completely independent, so the number of magnetic pole modules 60 can be freely selected. Because the linear motor selects the winding module 30 with completely independent magnetic flux path, and the winding module 30 can be detachably installed in the sliding groove of the click base, the number of winding modules 30 can be freely selected and installed on the motor base 10.
[0045] The present application adopts the double modular structure of the winding module 30 with completely independent magnetic flux path and the magnetic pole module 60 with completely independent magnetic flux path. The number of winding modules 30 and magnetic pole modules 60 can be flexibly selected to meet the requirements of different application scenarios, improve the applicability. For example, if you want to increase the stroke path of the linear motor, you can increase the number of winding modules 30, if you want to increase the output force of the linear motor, you can increase the number of magnetic pole modules 60, if you want to increase the stroke of the linear motor and the output force of the linear motor, you can increase the number of magnetic pole modules 60 and winding modules 30. The present application has simple structure, fast dynamic response speed, and can be used in semiconductor processing platform, intelligent multi-dimensional system motion platform, dispensing machine, microelectronic and optoelectronic packaging platform and a series of high-end precision industrial systems.
[0046] In an embodiment of the present application, as Figure 5 and Figure 6 The winding module 30 includes three double-sided coils with the same structure, and the three double-sided coils are a first double-sided coil 40a, a second double-sided coil 40b and a 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 a winding (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 connected to the first vertical rod 41 and the second vertical rod 42, and the first horizontal plate 43 is arranged adjacent to the motor base 10.
[0048] The first vertical pole 41 of the first double-sided coil 40a, the second vertical pole 42 of the second double-sided coil 40b, the first vertical pole 41 of the third double-sided coil 40c, the second vertical pole 42 of the first double-sided coil 40a, the first vertical pole 41 of the second double-sided coil 40b, and the second vertical pole 42 of the third double-sided coil 40c are arranged in the length direction of the mounting groove 11 in sequence. The first horizontal plate 43 and the second horizontal plate 44 of the first double-sided coil 40a are arranged in the same plane as the first horizontal plate 43 and the second horizontal plate 44 of the second double-sided coil 40b, respectively. 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 filling resin.
[0050] The double-sided coil is arranged in the above structure, which can ensure that the winding module 30 assembled by the first double-sided coil 40a, the second double-sided coil 40b, and the third double-sided coil 40c has an independent magnetic flux circuit. Since the structure of each double-sided coil is completely the same, 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 optional embodiments, a micro-flow channel can be arranged in the filling resin. The micro-flow channel is used to increase the contact area of the winding module 30 with air and increase the heat dissipation function of the winding module 30.
[0052] As shown in Figure 7 The double-module transverse flux linear motor further includes a limiting structure 50. The limiting structure 50 is arranged on both sides of each winding module 30 and can be detachably mounted on the motor base 10. Adjacent two limiting structures 50 clamp the winding module 30 located between the two limiting structures 50. The limiting structure 50 can ensure the stability of the installation of the winding module 30 on the motor base 10 and avoid the movement of the winding module 30 in the mounting groove 11 or the falling of the winding module 30 from the motor base 10 due to external force.
[0053] Further, as shown in Figure 2 The two sides of the groove bottom of the mounting groove 11 are provided with a seat clamping groove 12. The seat clamping groove 12 penetrates through both ends of the motor base 10 along the length direction of the motor base 10. The two sides of each seat clamping groove 12 are provided with an elastic clamping piece 13. The two ends of the elastic clamping piece 13 extend to the two ends of the seat clamping groove 12, as shown in Figure 8As shown, each limiting structure 50 is provided with a limiting plug-in protrusion 512 corresponding to each seat clamping groove 12, the limiting plug-in protrusion 512 is plugged into the clamping cavity formed between the two elastic clamping pieces 13, and the elastic clamping of the two elastic clamping pieces 13 to the limiting plug-in protrusion 512 realizes the fastening of the limiting structure 50 to the motor base 10.
[0054] Optionally, as shown in 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 clamping 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 an elastic clamping force, the vertical section 131 is used to provide clamping to the limiting plug-in protrusion 512, and can provide a larger contact area to the plug-in protrusion, under the combined action of the elastic clamping force of the arc-shaped curved section 132 and the larger clamping area of the vertical section 131 to the limiting plug-in protrusion 512, the stable clamping of the limiting structure 50 can be realized.
[0055] Optionally, as shown in Figure 4 As shown, the elastic clamping piece 13 is provided with a split groove 133, and the split groove 133 divides the elastic clamping piece 13 into a plurality of clamping sub-bodies 134. When the limiting plug-in 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 a large resistance to the limiting plug-in protrusion 512 inserted into the seat clamping groove 12, and it will be very laborious to insert the limiting plug-in protrusion 512 of the limiting structure 50 into the clamping cavity between the two elastic clamping pieces 13, but by dividing the elastic clamping piece into a plurality of clamping sub-bodies 134 through the split groove 133, the resistance of the elastic clamping piece 13 to the limiting plug-in protrusion 512 can be reduced, and the limiting plug-in protrusion 512 can be inserted between the elastic clamping pieces 13 with less labor.
[0056] Further, as shown in Figure 8As shown, the limiting structure 50 includes a first limiting block 51 and a second limiting block 52, the first limiting block 51 is provided with a block clamping groove 511, one end of the first limiting block 51 abuts one winding module 30 adjacent to the limiting structure 50, and the other end is penetrated by the block clamping groove 511, one end of the second limiting block 52 is slidably inserted into the block clamping groove 511, and the other end extends out of the block clamping groove 511 to abut the other winding module 30 adjacent to the 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, thereby adjusting 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 penetrates the second limiting block 52 into the block clamping groove 511 and is located on the first limiting block 51, and the block fastening screw 53 is threadedly connected with the first limiting block 51. When the length of the limiting structure 50 needs to be adjusted, the block fastening screw 53 is loosened away from the second limiting block 52, and then the second limiting block 52 is pulled relative to the first limiting block 51, so that the length of the limiting structure 50 can be adjusted, and when the limiting structure 50 reaches the required length, the block fastening screw 53 is tightened to fasten the second limiting block 52 to the first limiting block 51. The structure of the limiting structure 50 can adjust the distance between the winding modules 30, so that the winding module combination can meet the demand of the magnetic pole module 60 of multiple sizes. When the application scene changes and the required output force changes is not large, the size of the permanent magnet 62 of the magnetic pole module 60 can be changed to meet the demand of fine adjustment of the output force of the linear motor, for example, when the size of the permanent magnet 62 is increased to meet the demand of slightly increasing the output force of the linear motor, since the permanent magnet 62 is increased, the size of the entire magnetic pole module 60 will also be increased, and the magnetic field coverage range of the increased permanent magnet 62 is wide, so the winding modules 30 do not need to be distributed too densely on the motor base 10, and the distance between the winding modules 30 can be adjusted by the limiting structure 50, the number of the winding modules 30 is reduced, and the cost is reduced. When the permanent magnet 62 of the magnetic pole module 60 is reduced to meet the demand of slightly reducing the output force of the linear motor, since the permanent magnet 62 is reduced, the size of the entire magnetic pole module 60 will also be reduced, and the magnetic field coverage range of the reduced permanent magnet 62 is narrow, so the winding modules 30 need to be distributed densely on the motor base 10, and at this time, the distance between the winding modules 30 can be reduced by reducing the length of the limiting structure 50 to ensure the output force of the linear motor. In summary, the length-adjustable limiting structure 50 can make the winding module combination match the magnetic pole module 60 of different sizes to slightly increase or slightly reduce the output force of the linear motor, and the applicability of the winding module combination is improved.
[0057] In other possible embodiments, the limiting structure 50 can be removed, and the coil winding 20 can be clamped in the mounting groove 11 by the friction force between itself and the groove wall of the mounting groove 11.
[0058] In one embodiment of the present application, Figure 9 As shown, the yoke 61 includes two yoke vertical plates 611, an yoke horizontal plate 612, two yoke extension plates 613 and two sliders 614. The two yoke vertical plates 611 are arranged opposite to each other. The ends of the two yoke vertical plates 611 away from the motor base 10 are connected by the yoke horizontal plate 612, and the other ends are respectively connected to the two yoke extension plates 613. The yoke vertical plates 611 and the yoke horizontal plates 612 form a clearance cavity 615; the yoke extension plate 613 extends from the yoke vertical plates 611 in the direction away from the clearance cavity 615; the two sliders 614 are respectively installed on the two yoke extension plates 613, and are respectively slidably connected to the two guide rails 20; the slider 614 is located on the side of the yoke extension plate 613 facing away from the yoke horizontal plate 612.
[0059] Further, such as Figure 10 As shown, the yoke extension plate 613 is provided with an yoke mounting groove 6131 passing through the yoke vertical plate 611, and the permanent magnet 62 is provided with a plug-in plate 621 extending into the yoke mounting groove 6131 on the side facing the yoke vertical plate 611. The plug-in plate 621 is fixed to the yoke extension plate 613 by a plate fastening screw 63. The plate fastening screw 63 passes through the yoke extension plate 613 from the side of the yoke extension plate 613 close to the yoke horizontal plate 612 and extends into the yoke mounting groove 6131, and is pressed against the plug-in plate 621 to fasten the plug-in plate 621 to the yoke extension plate 613, thereby fixing the entire permanent magnet 62 on the yoke 61, wherein the plate fastening screw 63 is threadedly connected to the yoke extension plate 613. The arrangement of the iron yoke mounting groove 6131 in the iron yoke extension plate 613 and the plug-in plate 621 on the permanent magnet 62 can adjust the distance between the two permanent magnets 62 and achieve fine-tuning of the output force of the linear motor. When the distance between the two permanent magnets 62 needs to be adjusted, 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 of the permanent magnet 62 will be closer to the magnetic flux path generated by the radial winding module 30, thereby increasing the magnetic flux generated by the permanent magnet 62 and the winding module 30, thereby achieving the purpose of increasing 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 in the direction away from the magnetic flux path of the winding module 30, thereby reducing the magnetic flux that the permanent magnet 62 can generate with the winding module 30, thereby achieving the purpose of reducing the output force of the linear motor.
[0060] In one embodiment of the present 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 belt 70, and the connecting belt 70 detachably links the extension plates of the iron yoke 61 of the two magnetic pole modules 60 through a clamping structure.Figure 10 and Figure 12 As shown in the figure, the clamping structure includes a belt clamping protrusion 71 arranged on the connecting belt 70 and a clamping hole 6132 arranged on the iron yoke extension plate, and the belt clamping protrusion 71 is inserted into the clamping hole 6132. The number of magnetic pole modules 60 is determined according to the required force of the application, and after being installed on the motor base 10, the linear motor will vibrate during operation. If the magnetic pole modules 60 are not connected by the connecting belt 70, the vibration will drive the magnetic pole modules 60 to separate, affecting the walking stroke. The problem can be solved by connecting the magnetic pole modules 60 through the connecting belt 70.
[0061] The above describes the preferred embodiments of the present application. It should be noted that for those skilled in the art, without departing from the principles of the present application, a number of improvements and refinements can be made, and these improvements and refinements should also be considered as the protection scope of the present application.
