Description

Technical Field

[0001] The invention relates to a mounting device for inserting magnets into magnet receptacles of a rotor of an electric machine. The invention also comprises a system comprising a rotor and a mounting device according to the invention and a method for inserting magnets into magnet receptacles of a rotor of an electric machine. Background Art

[0002] In particular, an electric machine is to be understood as a machine for converting electrical energy into kinetic energy and / or a machine for converting kinetic energy into electrical energy. In particular, the term is to be understood as meaning electric motors and generators.

[0003] When manufacturing the rotor of an electric machine, the magnets are inserted into the rotor or rotor lamination stack. Within the rotor, the magnets have different orientations.

[0004] In order to insert magnets into the rotor, it is known in the prior art to insert the magnets into the rotor or rotor lamination stack using a robot. To this end, a robot, specifically a robot arm, collects the magnets from a magazine and inserts them individually into a loading plate or directly into the rotor. In particular, a magazine is understood to mean a storage device in which the magnets are stored.

[0005] Instead of a robot, a device specifically provided for this purpose can also be provided for inserting the magnets into the rotor or the lamination stack.

[0006] In this regard, for example, JP 2016 208 695 A describes a workpiece insertion apparatus. The workpiece insertion apparatus inserts a magnet into an insertion hole of a rotor. For this purpose, the workpiece insertion apparatus includes a clamp portion configured to pick up the magnet in a predetermined orientation and transfer the magnet to the insertion hole.

[0007] Alternatively, CN 207 251 402 U describes an automated device for feeding magnets into a rotor. For this purpose, the device comprises a guide arm that separately transfers magnets with different orientations to the rotor.

[0008] KR 101 972 348 B1 describes an apparatus for inserting magnets into a rotor core. The apparatus includes a magnet feeding unit that inserts the magnets into an insertion hole of the rotor core, and a magnet placement unit into which a plurality of magnets supplied by the magnet feeding unit are temporarily inserted before being inserted into the insertion hole of the rotor core. The apparatus also includes a magnet insertion unit positioned below the magnet placement unit and above the rotor core, the magnet insertion unit being moved by the rotor core feeding unit so that the plurality of magnets temporarily inserted into the magnet placement unit are inserted together into the insertion hole of the rotor core.

[0009] In the rotor of an electric motor, the magnets have different orientations, specifically different position orientations. Typically, for example, the magnets are all arranged to have the same orientation, such as in a bubble cap. Therefore, the magnets must be placed in different positions or orientations. Summary of the Invention

[0010] The invention gives itself the object of providing a mounting device, a system and a method by means of which magnets can be fed to a rotor in a particularly simple, rapid and assured manner, in particular in a predetermined orientation.

[0011] To achieve this object, the present invention provides an installation device, a system and a method having the features of the technical solution of the present invention. In the technical solution of the present invention, advantageous embodiments having useful and meaningful improvements of the present invention are pointed out.

[0012] The present invention provides an installation device for inserting magnets into a magnet receiving portion of a rotor of an electric motor. Specifically, the term "magnet receiving portion" refers to a channel or recess configured to receive magnets. For example, the magnets can be stacked sequentially in the magnet receiving portion. Specifically, the shape of the magnet receiving portion is adapted to the shape of the magnets. For example, if the magnets are configured to have a rectangular cross-section, the magnet receiving portion is configured to have a rectangular cross-section.

[0013] The mounting device comprises an alignment device configured to accommodate and align the magnet. Specifically, "alignment" means that the alignment device is configured to orient the magnet or place the magnet in a predetermined position. For this purpose, the alignment device for aligning and accommodating the magnet comprises at least one channel. In other words, the magnet can be accommodated in the channel, and due to the shape or arrangement of the channel, the magnet can be moved to align or orient in a predetermined position. Specifically, "channel" means a pipe or a tubular connecting passage. In addition, the shape of the at least one channel is adapted to the shape of the magnet. In other words, the cross-section of the channel can be adapted to the outer contour of the magnet. For example, if the magnet is configured to have a rectangular cross-section, the channel is configured to have a rectangular cross-section. In addition, at least one channel is preferably larger than the magnet or magnets to a certain extent, specifically so that the magnet or magnets can slide or glide through the channel.

[0014] The channel has a channel inlet, which is arranged at an end face or end surface of the alignment device and through which magnets can be fed into the channel; and a channel outlet, which is arranged opposite the channel inlet and at an end face of the alignment device opposite the end face and through which magnets can be discharged from the channel, in particular for insertion into a magnet receiving portion of the rotor. In other words, due to the channel inlet and the channel outlet, at least one channel can be configured to be open on two or both ends.

[0015] Furthermore, it is provided that at least one channel is twisted. In this case, the at least one channel can be twisted in such a way that the channel inlet and the channel outlet are oriented differently relative to each other with respect to the plane of the respective end face. Specifically, the "plane of the respective end face" means a cross-sectional surface that coincides with a cross-section of the mounting device. Specifically, the cross-sectional surface extends perpendicularly to the main extension direction of the mounting device. In other words, the at least one channel can be twisted in such a way that the channel inlet has a different orientation than the channel outlet. Specifically, "twisting" means twisting or spiraling, or that at least one channel is wound around its own axis.

[0016] The advantage of the alignment device is that the number of moving parts required to align the magnets can be reduced. Furthermore, shorter cycle times are required for manufacturing or inserting the magnets into the rotor. Furthermore, the magnets can be fed linearly, and each magnet can be fed linearly in the same manner. Due to this specific configuration of the at least one channel, the magnets can be aligned or oriented in a particularly simple and reliable manner, specifically to correspond to the alignment or orientation of the magnet receptacles.

Furthermore, the alignment device preferably has a cylindrical or columnar shape. In this case, the end face preferably forms a circular base area of ​​the cylindrical alignment device. Particularly preferably, the individual channels are twisted in a clockwise and / or counterclockwise direction.

Thus, the channel outlets of the channels arranged side by side are arranged in a sawtooth shape in the circumferential direction. Furthermore, the channel outlets are tilted in particular in an alternating manner towards the radius, in particular the end face, of the alignment device and / or away from the radius of the alignment device. Due to the several channels, several or even all of the magnet receptacles can be filled at once. Thus, time and costs can be saved in the production of the rotor.

In the exemplary embodiments, the components described in the embodiments each constitute individual features of the present invention, which are considered independently of one another and in each case also independently of one another to develop the present invention, and are therefore considered as constituent elements of the present invention, either individually or in combinations different from the ones shown. Furthermore, the described embodiments may also be supplemented with other features of the present invention that have already been described.

[0053] In the schematic representation, Figure 1 A rotor 10 for an electric machine is shown. In particular, an electric machine is understood to be a machine for converting electrical energy into kinetic energy and / or a machine for converting kinetic energy into electrical energy. In particular, the term should be understood to mean electric motors and generators.

[0054] The rotor 10 includes a lamination stack 12 and magnets 14. For clarity, not all magnets 14 are provided with reference numerals. The magnets 14 are housed in the lamination stack 12 of the rotor 10. To this end, the rotor 10 includes a magnet receptacle 16 in which the magnets 14 are disposed or housed. Specifically, the magnet receptacle 16 is adapted to the shape of the magnets 14. In this case, the cross-section of the magnets 14 is rectangular. Therefore, the magnet receptacle 16 is also configured to have a rectangular cross-section. The magnet receptacle 16 is configured as a channel, a conduit, or a recess. Specifically, the magnet receptacle 16 extends in a straight manner or along the main extension direction of the rotor 10 from one end face 18 of the rotor 10 to the opposite end face of the rotor 10 in the main extension direction. Specifically, the main extension direction of the rotor 10 extends in the direction of the rotational axis of the rotor 10. The magnet receptacles 16 and / or the magnets 14 are arranged side by side in the circumferential direction of the rotor 10, specifically at a predetermined distance from each other. The magnets 14 and / or the magnet receptacles 16 have a predetermined orientation in the rotor 10 or in the lamination stack 12 of the rotor 10. The lamination stack 12 of the rotor 10 has a cylindrical shape. Figure 1 It is evident that the magnets 14 and / or the magnet receptacles 16 are alternately inclined toward a radius of the laminated core 12 of the rotor 10 or away from a radius of the laminated core 12 of the rotor 10. Overall, the magnet receptacles 16 or the magnets 14 are arranged in a zigzag arrangement in the rotor 10 or in the laminated core 12 of the rotor 10.

[0055] The mounting device 20 is provided to enable the magnets 14 to be placed in a predetermined arrangement or orientation, in particular in the magnet receptacles 16 of the rotor 10 . Figure 2 、 Figure 3a as well as Figure 3b A portion of a system with a mounting device 20 is shown. Figures 4 to 8 A system 58 having another embodiment of a mounting device 20 is shown. Figure 9 and Figure 10 A system 58 having another embodiment of a mounting apparatus 20 is shown. Figures 11 to 13 A system 58 is shown having another embodiment of the mounting apparatus 20 and the rotor 10. Figures 2 to 10 , the system 58 and the mounting apparatus 20 and embodiments thereof, as well as methods for mounting the rotor 10 with the magnets 14, will be discussed in greater detail.

[0056] As according to Figure 2 It is evident that the system 58 comprises a mounting device 20 with a feeding device 22 and an alignment device 24, and a rotor 10. Instead of the rotor 10 being adjacent to the alignment device 24, provision can be made for a receiving device 26 to be adjacent to the alignment device 24, such as Figures 11 to 13 Thus, instead of the rotor 10 adjacent to the alignment device 24, it may be provided that Figures 2 to 5A schematically arranged receiving device 26 is shown adjacent to the alignment device 24 .

[0057] Specifically, in the vertical direction or main extension direction H of the feeding device 20 or the system 58, the alignment device 24 is arranged between the feeding device 22 and the rotor 10 or the receiving device 26. The feeding device 22 is configured to feed the magnets 14 to the alignment device 24. For this purpose, the feeding device 22 has at least one feeding area 28. In each case, the feeding area 28 is suitable for receiving one magnet 14. The feeding area 28 has an opening, via which one of the magnets 14 can be fed to the feeding area 28 in each case. Due to the opening on one side, the feeding area 28 preferably has a U-shape. In other words, the feeding area 28 can be formed by a U-shaped recess in the feeding device 22. Specifically, the shape of the feeding area 28 is adapted to the shape or contour of the magnet 14 to be received. In addition, the mounting device 20 has a conveying unit (not shown in the figure) that is configured to feed the magnets 14, in particular radially, to the feeding area 28.

Preferably, the channel outlet 34 or the end region of the channel 30 leading to the channel outlet 34 has a funnel shape. In order to enable the magnet 14 or magnets 14 to be slid or moved individually, specifically one after another, through the at least one channel 30, the extent or size of the channel 30, specifically with respect to the cross-section of the mounting device 20, is preferably greater than the extent or size of the magnet 14 or magnets.

[0059] At least one feed region 28 of the feed device 22 is associated with or assigned to a channel 30 of the alignment device 24. In this case, the at least one feed region 28 and the at least one channel 30 are arranged adjacent to one another in the main extension direction H of the alignment device 24 in such a way that the magnet 14 can be inserted from the feed region 28 via the channel inlet 32 ​​into the channel 30.

[0060] The magnets 14 are passed from at least one channel 30 of the alignment device 24 via a channel outlet 34 to the rotor 10 or the lamination stack 12 of the rotor 10. For this purpose, the rotor 10 includes a magnet receptacle 16. The magnet receptacle 16 is configured as a channel or a duct. In this case, the shape of the magnet receptacle 16, in particular with respect to the cross-section, is adapted to the shape of the magnets 14. Furthermore, the orientation or alignment of the magnet receptacle 16 is adapted to the orientation or alignment of the channel outlet 34. Specifically, the magnet receptacle 16 extends in a straight manner in the main extension direction of the rotor 10 or the system 58 from one end face 18 of the rotor 10 facing the channel outlet 34 to the opposite end face of the rotor 10 or the lamination stack 12. The magnet receptacle 16 is configured to accommodate the magnets 14, in particular in the vertical direction or main extension direction of the rotor 10 or the system 58. The magnets 14 are preferably stacked one behind the other in the vertical direction or main extension direction H of the system 58 or of the rotor 10 in the magnet receptacles 16 of the laminated core 12 .

[0061] If Figures 11 to 13 The system 58 shown includes a receiving device 26, so the magnet 14 first passes from at least one channel 30 of the alignment device 24 via the channel outlet 34 to the receiving device 26. The receiving device 26 is preferably configured as a loading plate. Figure 12 As shown, the receiving device 26 has at least one receiving portion 40. The at least one receiving portion 40 is configured as a channel or a duct. In this case, the shape of the receiving portion 40, in particular with respect to the cross-section, is adapted to the shape of the magnet 14. In addition, the orientation or alignment of the at least one receiving portion 40 is adapted to the orientation or alignment of the channel outlet 34.

The at least one receiving portion 40 is configured for accommodating the magnet 14, in particular in the vertical direction or main extension direction H of the system 58 or the mounting device 20. Preferably, the magnets 14 are stacked one after the other in the receiving portion 40 of the receiving device 26 in the vertical direction or main extension direction H of the system 58 or the mounting device 20.

[0062] As according to Figure 3a and Figure 3b It is evident that at least one channel 30 of the alignment device 24 is twisted. Specifically, "twisted" means that at least one channel 30 is rotated about an axis. Specifically, the channel inlet 32 ​​has an orientation or alignment that is different from the orientation or alignment of the channel outlet 34. Figure 3a In the embodiment of the present invention, at least one channel 30 is rotated or twisted in a counterclockwise direction, as shown by arrow P1. Figure 3b , at least one channel 30 is rotated or twisted in a clockwise direction, as indicated by arrow P2.

[0063] As according to Figure 4 and Figure 5 It is clear that the alignment device 24 has several channels 30, wherein the channels 30 are arranged side by side in the alignment device 24 in the circumferential direction of the alignment device 24. For the sake of clarity, not all channels 30, feed areas 28, or magnet receptacles 16 are provided with reference numerals. In this case, the channels 30 extend through the alignment device 24, specifically along the main extension direction H of the mounting device 20, from an end face 36 of the alignment device 24 to an opposite end face 38 of the alignment device 24. The channels 30 twist alternately in the clockwise and counterclockwise direction; specifically, the channels 30, starting from the channel inlet 32, are twisted in such a way that the channel outlet 34 has a different orientation than the channel inlet 32.

[0064] As according to Figure 5 It is clear that the feed device 22 of the mounting device 20 has several feed areas 28 and the rotor 10 or the lamination stack 12 of the rotor 10 has several magnet receptacles 16. In particular, one feed area 28, one channel 30 and one magnet receptacle 16 are in each case associated with one another. In the exemplary embodiment, the mounting device 20 has 14 feed areas 28, 14 channels and 14 magnet receptacles 16. Furthermore, the orientation or alignment of the magnet receptacles 16 is adapted to the orientation or alignment of the channel outlets 34 associated with the magnet receptacles 16. As according to Figure 5 It is evident that the magnet receptacles 16 are alternately inclined towards a radius of the rotor 10 or away from a radius of the rotor 10. Overall, the magnet receptacles 16 are arranged in a zigzag arrangement in the laminated core 12.

[0065] If Figures 11 to 13 The system 58 shown also comprises a receiving device 26, the receiving device 26 of the mounting device 20 preferably having several receiving sections 40. In particular, one feed area 28, one channel 30 and one receiving section 40 and / or one magnet receiving section 16 of the rotor 10 are in each case associated with one another. In the exemplary embodiment, the mounting device 20 has 14 feed areas 28, 14 channels and 14 receiving sections 40 and / or 14 magnet receiving sections 16. Furthermore, the orientation or alignment of the receiving sections 40 is adapted to the orientation or alignment of the channel outlets 34 associated with the receiving sections 40. The receiving sections 40 of the receiving device 26 are in this case oriented like the magnet receiving sections 16 of the rotor 10. As according to Figure 5 It is similarly evident with respect to the rotor 10 that Figures 11 to 13 The receiving portions 40 of the receiving device 26 depicted in FIG are alternately inclined towards a radius of the receiving device 26 or away from a radius of the receiving device 26. Overall, the receiving portions 40 are provided in the receiving device 26 in a zigzag arrangement.

[0066] As according to Figures 5 to 7It is obvious that the feeding device 22 preferably has several feeding areas 28. In this case, one feeding area 28 is respectively associated with or assigned to a channel inlet 32 ​​of a channel 30 of the alignment device 24. Figure 5 、 Figure 6 、 Figure 11 as well as Figure 12 It is evident that the feeding device 22, the alignment device 24 and the receiving device 26 have a cylindrical shape. Figures 5 to 7 It is evident that the magnets 14 are fed radially to the respective feed regions 28 of the feed device 22 or are inserted or pushed into the respective feed regions 28 .

[0067] In addition, according to Figure 8 It is clear that the mounting device 20 can have a movement device 42. For example, the movement device 42 can be configured as a plunger. The movement device 42 is configured to apply a force to the magnet 14 in the channel 30 or channels 30, specifically along the main extension direction H of the mounting device 20. For example, the movement device 42 can be guided into the respective channel 30 via the channel inlet 32. Preferably, the mounting device 20 has several movement devices 42 or plungers. In particular, one movement device 42 is associated with or assigned to each channel 30.

[0068] Figure 9 and Figure 10 Another embodiment or improvement of the alignment device 24 of the mounting device 20 of the system 58 is shown. In order to adjust the falling speed of the individual magnets 14 in the channel 30 or multiple channels 30, the mounting device 20 can have a braking member. For this purpose, the channel 30 is open to the outer surface 44 of the alignment device 24. The outer surface 44 extends vertically from the end face 36 of the alignment device 24 to the opposite end face 38 of the alignment device 24. Since the alignment device 24 has a cylindrical shape, the outer surface 44 can also be configured as a jacket surface. The end face or end surface preferably forms a circular relative base area. The braking member or several braking members are arranged or accommodated in an opening 46 or multiple openings 46, which are specifically arranged in the circumference of the alignment device 24. For example, the braking member can be constructed as a brush. Due to the opening 46, one channel or multiple channels 30 can be configured in a T-shape at least in some parts. The channel is divided into two channel areas or channel parts by the opening 46. The first channel area is as already combined Figures 2 to 8 The second passage region or opening 46 extends from the first passage region toward the outer surface 44 of the alignment device 24. In addition, the opening 46 may extend from the end face 36 of the alignment device 24 toward the opposite end face 38 of the alignment device 24.

[0069] As according to Figures 11 to 13It is apparent that the system 58 has an embodiment of the mounting apparatus 20 and the rotor 10. Figures 11 to 13 In an embodiment of the present invention, the mounting device 20 further comprises a sliding member 48. The sliding member 48 is configured as a plate or plate-like member or workpiece. The sliding member 48 is arranged at the lower side 50 of the receiving device 26 opposite the alignment device 24. In this case, the sliding member 48 is configured in such a way that the sliding member 48 completely covers the lower side 50 of the receiving device 26. The sliding member 48 is configured to close or close or cover at least one receiving portion outlet, preferably all receiving portion outlets, in the holding position, and the sliding member 48 is configured to clear or open at least one receiving portion outlet, in particular the receiving portion outlet, in the clearing position. For this purpose, the sliding member 48 is slidably supported in a direction as indicated by the arrow 52, ​​perpendicular to the main extension direction H of the mounting device 20. In other words, the sliding member 48 can move back and forth between the holding position and the clearing position.

[0070] The radial insertion, movement, or transport of magnet 14 into feed region 28 is indicated by arrow 54. Furthermore, alignment device 24 is rotatably supported about the axis of mounting device 20, as indicated by arrow 56. Preferably, alignment device 24 is configured as a turret. Sliding member 48 is provided between rotor 10 and receiving device 26. Furthermore, feed device 22 and receiving device 26 are coupled or connected to one another.

[0071] The method for inserting or installing magnets into the rotor 10 of an electric machine is described in more detail below:

[0072] In a first method step, a magnet 14 is provided. Figure 11 It is obvious that the magnets 14 are arranged adjacent to each other. Then, in particular by means of a conveying unit, the magnets 14 are pushed radially into at least one feeding area 28 of the feeding device 22. Thus, the magnets 14 are conveyed one by one from the feeding area 28 via at least one channel entrance 32 to the channel 30 and aligned therein. From the channel 30, the magnets 14 directly reach the receptacle 40 of the receptacle device 26 connected to the channel 30. The receptacle 40 is filled with the magnets 14 conveyed through the channel 30. The magnets 14 are stacked in sequence in the receptacle 40. As long as the receptacle 40 is filled with magnets 14, the sliding member 48 is in a holding position in which the sliding member 48 closes the receptacle outlet. If the receptacle 40 is already filled, i.e. completely or partially filled, the sliding member 48 moves to a clearing position in which the sliding member 48 clears the receptacle outlet. Therefore, in a further method step, the magnet 14 is transferred from the receptacle 40 into the magnet receptacle 16 of the rotor 10 associated with the receptacle 40 .

[0073] Alternative exemplary embodiments are discussed below:

[0074] The alignment device 24 can also be configured as a turret. For this purpose, the magnet feed is preferably stationary. The turret separates the magnets 14 and the magnets 14 are collected in the correct orientation in the receiving device 26 via the channel 30. The magnets 14 are pushed into the channel 30 by a plunger or fall into the channel 30 due to gravity. In this case, the receiving device 26 is connected to the turret, in particular firmly connected to the turret. Once the receiving device 26 has been filled, the sliding member 48 releases the magnets 14. The magnets can then be pushed into the turret. Alternatively, the rotor 10 can be arranged directly below the alignment device 24; in this case, the mounting device 20 does not include the receiving device 26. In this case, the rotor 10 is stationary. The magnets 14 are provided by a stationary feed.

[0075] In general, the examples show how an apparatus for automatically mounting magnets in a rotor is provided by the present invention.

[0076] The magnets are fed into the device and separated. A channel, twisted and somewhat larger than the magnets, is located within the device. The magnets can be slid into the channel into the correct orientation without being fully rotated.

[0077] The magnets thus have the desired orientation in the rotor. Depending on the configuration of the channels, the magnets can in this case rotate both clockwise and counterclockwise.

[0078] The device can also be configured as a turret. For this purpose, the magnet feed is stationary. The turret separates the magnets. The magnets are pushed into the channel or fall into it due to gravity. The rotor can be positioned directly below the device. Both horizontal and vertical configurations are possible. In this case, the rotor is stationary.

[0079] The channel may be configured in such a way that the plunger may push the magnet into the rotor.

[0080] The channel can also be configured to be open, for example to accommodate brushes for braking magnets.

[0081] The following description is based on an example of a device having a loading plate or a receiving device and a slide or a sliding member:

[0082] The magnets are supplied via a stationary feed. A turret separates the magnets, and they are collected in the correct orientation via channels on a loading plate, or receiving device. The loading plate is connected, specifically securely, to the turret. Once the loading plate is filled, a slide, or sliding member, releases the magnets. The magnets can then be pushed into the turret.

[0083] The advantages of the present invention are that the number of movable parts can be reduced. Furthermore, a shorter cycle time is required for manufacturing or inserting the magnets into the rotor. Furthermore, the magnets can be fed linearly and in the same manner for each magnet.
