[0061] Specifically, if Figure 2 As shown, the back iron module 72 further includes a lifting drive 724, the fixed end of which is disposed on the frame 721, and the output shaft of the lifting drive 724 passes through the first slide 722 and is connected to the carrier 727 to drive the carrier 727 to move along the Z axis, so as to drive the carrier 727 and the back iron 701 to move along the Z axis in a direction away from the contoured back iron, so that the magnetic steel and the magnetic steel pressure plate are separated from the contoured back iron respectively. In this embodiment, the lifting drive 724 can be specifically a linear cylinder.

[0062] Furthermore, if Figure 2 and Figure 3 As shown, a guide column 726 and a guide sleeve 725 are connected between the first slide 722 and the carrier 727. The guide sleeve 725 is fixedly set on the first slide 722. One end of the guide column 726 is fixedly connected to the bottom end surface of the carrier 727, and the other end of the guide column 726 is slidably set in the guide sleeve 725 along the Z axis.

[0063] By providing the guide sleeve 725 and the guide column 726, a guiding effect can be provided for the movement of the carrier 727 on the Z axis, thereby ensuring the guiding and reliability of the movement of the carrier 727 on the Z axis relative to the first slide 722.

In this embodiment, the slide rail 7211 is arranged on the frame 721, and the slider 7221 is arranged on the first slide 722.

[0065] Specifically, glue is coated on the side of the soft magnetic composite sheet that is in contact with the back iron 701, so that when the soft magnetic composite sheet is flipped and assembled on the back iron 701, it can be directly bonded to the back iron 701, thereby ensuring the installation stability and reliability of the soft magnetic composite sheet in the back iron 701.

[0066] Further, based on the characteristics of the glue used, since the glue needs to have suitable casting performance within a specific temperature range, the back iron module 72 in this embodiment also includes a heating element, which is arranged on the carrier 727. The heating element is used to heat the back iron 701. When the glue coated on the soft magnetic composite sheet contacts the heated back iron 701, the glue coated on the soft magnetic composite sheet can be evenly cast and distributed between the soft magnetic composite sheet and the back iron 701 when the glue is attached to the back iron 701, so that the glue has suitable casting performance, thereby ensuring the bonding reliability between the soft magnetic composite sheet and the back iron 701. Among them, the heating element can be specifically an electric heating wire.

[0067] Furthermore, if Figure 2 and Figure 3 As shown, the back-iron module 72 also includes a pressing component 728. A plurality of pressing components 728 are arranged on the outer periphery of a support surface 7271 on the carrier 727 for placing the back-iron 701. The pressing components 728 can move radially along the support surface 7271 and along the Z-axis to clamp the back-iron 701, thereby stably setting the back-iron 701 on the carrier 727, which is beneficial for the subsequent flipping and assembly of the structure in the contoured back-iron into the back-iron 701.

[0068] Specifically, Figure 3 , Figures 5 to 7As shown, the pressing assembly 728 includes a pressing drive member 7281, a pressing block 7282 and a lifting drive member 7284; wherein, the fixed end of the pressing drive member 7281 is arranged on the carrier 727; the top of the pressing block 7282 is provided with an overhanging flange 7283, and the driving end of the pressing drive member 7281 is connected to the pressing block 7282 to drive the pressing block 7282 to move radially along the supporting surface 7271, so that the gap of the overhanging flange 7283 is located directly above the outer edge of the back iron 701; the fixed end of the lifting drive member 7284 is arranged on the carrier 727, and the output shaft of the lifting drive member 7284 can pass through the supporting surface 7271 upward along the Z axis and push the back iron 701, so that the back iron 701 moves upward along the Z axis until its outer edge abuts against the overhanging flange 7283, so that the overhanging flange 7283 clamps the back iron 701.

[0069] like Figure 5 and Figure 7 As shown, the pressure block 7282 is driven by the pressure driving member 7281 to move radially along the support surface 7271 so that the gap of the protruding flange 7283 is located directly above the outer edge of the back iron 701, that is, there is a certain gap between the protruding flange 7283 of the pressure block 7282 and the outer edge of the back iron 701 on the Z axis. The gap can ensure that the pressure block 7282 can smoothly expand and contract radially along the support surface 7271, so that the back iron 701 does not interfere with the expansion and contraction of the pressure block 7282.

[0070] In addition, the back iron 701 is pushed upward along the Z-axis by the lifting drive part 7284, so that the back iron 701 moves upward along the Z-axis until its outer edge abuts the protruding flange 7283, so that the protruding flange 7283 clamps the back iron 701 to eliminate the gap between the protruding flange 7283 and the back iron 701 on the Z-axis; on the one hand, the back iron 701 can be set on the carrier 727 more stably to ensure that the position of the back iron 701 will not be relatively offset; on the other hand, when it is flipped and assembled to the back iron 701, the magnetic attraction between the magnet and the back iron 701 will not directly suck the back iron 701 with a gap between the protruding flange 7283 from the carrier 727 and hit the soft magnetic composite sheet, thereby avoiding the soft magnetic composite sheet from being damaged by the impact, so as to better protect the soft magnetic composite sheet. There are multiple lifting driving components 7284 , and the multiple lifting driving components 7284 are circumferentially arranged on the carrier 727 to ensure synchronization and balance of the lifting of the back iron 701 by the lifting driving components 7284 .

In this embodiment, the fastener can be a screw.

[0073] Specifically, Figure 1 and Figure 8 As shown, the fastening module 73 includes a second slide 731, a mounting seat 733, a rotating ring 734, a rotating assembly and a fastening assembly 736; wherein the second slide 731 is slidably arranged along the X-axis, and a vertical frame 732 extending along the Z-axis is connected to the second slide 731; the mounting seat 733 is fixedly connected to the vertical frame 732, the rotating assembly is arranged on the mounting seat 733, the rotating ring 734 is rotatably arranged on the mounting seat 733 around the Z-axis, the rotating assembly is used to drive the rotating ring 734 to rotate around the Z-axis, and the fastening assembly 736 is slidably connected to the rotating ring 734 along the Z-axis.

[0074] Specifically, if Figure 8 As shown, the rotating assembly includes a rotating driving member 7354, a driving wheel 7351 and a synchronous belt 7352; wherein the fixed end of the rotating driving member 7354 is arranged on the mounting seat 733; the two ends of the synchronous belt 7352 are respectively sleeved on the driving wheel 7351 and the rotating ring 734, and the driving end of the rotating driving member 7354 is connected to the driving wheel 7351 to drive the driving wheel 7351 to rotate around the Z axis, so that the rotating ring 734 can be driven to rotate around the Z axis through the rotation of the synchronous belt 7352, so that the fastening assembly 736 on the rotating ring 734 can be rotated stepwise around the Z axis by an angle, so that the fastening assembly 736 can be rotated to align with each magnetic steel pressure plate in turn, so as to lock each magnetic steel pressure plate to the back iron 701 through the fasteners. In this embodiment, the rotating driving member 7354 can be specifically a motor, and a plurality of guide wheels 7353 are also abutted on the synchronous belt 7352.

[0075] Furthermore, if Figure 1 and Figure 8As shown, the fastening assembly 736 includes a connecting plate 7361, a vertical driving member 7362 and a fastening member 7363; wherein the connecting plate 7361 is fixedly connected to the rotating ring 734; the fixed end of the vertical driving member 7362 is arranged on the connecting plate 7361, and the driving end of the vertical driving member 7362 is connected to the fastening member 7363 to drive the fastening member 7363 to move along the Z axis, so that the fastening member 7363 passes through the contoured back iron downward along the Z axis and then drives the fastener into the magnetic steel pressure plate, the soft magnetic composite sheet and the back iron 701, so as to achieve locking the magnetic steel pressure plate to the back iron 701. In this embodiment, the vertical driving member 7362 can be specifically a cylinder, and the fastening member 7363 can specifically adopt a screw driving structure commonly used in the prior art, and the specific structure of the fastening member 7363 and the process of driving the fastener are not described in detail here.

[0076] It is worth noting that if Figure 8 As shown, a plurality of fastening assemblies 736 are provided on the rotating ring 734, so that the plurality of fastening assemblies 736 can simultaneously drive a plurality of fasteners into the back iron 701 on the magnetic steel pressing plate through the fastening members 7363 of the plurality of fastening assemblies 736, so as to quickly and efficiently achieve the locking between the magnetic steel pressing plate and the back iron 701, and the working efficiency is high. In this embodiment, two fastening assemblies 736 are provided on the rotating ring 734, and the number of fastening assemblies 736 is not limited here.

[0077] It is worth noting that when the flip module 71 drives the contoured back iron and the magnets, magnet pressure plate and soft magnetic composite sheet thereon to rotate as a whole around the X-axis in the direction close to the back iron 701 until the contoured back iron rotates to be parallel and located above the back iron 701, it is necessary to first perform a magnetization operation on the magnets on the back iron 701, that is, push the magnets radially outward along the back iron 701 so that the outer wall surface of the magnets abuts against the inner wall surface of the back iron 701, and then use the fastening module 73 to lock the magnet pressure plate on the back iron 701.

[0078] The specific working process of the device assembled to the back iron in this embodiment is as follows:

[0079] First, the first slide 722 is slid along the Y-axis to the flip module 71 to drive the carrier 727 and the back iron 701 thereon to move to the flip module 71; then the flip module 71 drives the contoured back iron and the magnetic steel, magnetic steel pressure plate and soft magnetic composite sheet thereon to rotate as a whole around the X-axis in a direction close to the back iron 701, until the contoured back iron rotates to be parallel and located above the back iron 701.

[0080] At this time, the glue on the soft magnetic composite sheet on the contoured back iron is evenly cast and distributed between the soft magnetic composite sheet and the back iron 701 when it is in contact with the back iron 701, so that the soft magnetic composite sheet and the back iron 701 are bonded and fixed; at this time, the soft magnetic composite sheet is bonded to the back iron 701, and the magnetic steel and the magnetic steel pressure plate are still located on the contoured back iron.

[0081] Then, the fastener 7363 is driven downward along the Z-axis through the contoured back iron and then into the magnetic steel pressure plate, the soft magnetic composite sheet and the back iron 701 to lock the magnetic steel pressure plate onto the back iron 701; the rotating ring 734 is then driven to rotate around the Z-axis by the rotation of the synchronous belt 7352, so that the fastening assembly 736 on the rotating ring 734 rotates stepwise around the Z-axis by an angle, so that the fastening assembly 736 of the fastening assembly 736 is rotated to align with each magnetic steel pressure plate in turn, so that each magnetic steel pressure plate can be locked to the back iron 701 through the fastener.

[0082] Finally, the flip module 71 is flipped and reset or the carrier 727 drives the back iron 701 to be pulled away from the contoured back iron, so that the magnetic steel / magnetic steel pressure plate is completely separated from the contoured back iron. At this time, the soft magnetic composite sheet is bonded to the back iron 701, and the magnetic steel and the magnetic steel pressure plate are transferred as a whole to the soft magnetic composite sheet; thereby completing the entire process of flipping and assembling the magnetic steel / magnetic steel pressure plate and the soft magnetic composite sheet in the contoured back iron into the back iron 701.
