[0052] The present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It is to be understood that the specific embodiments described herein are only used to explain the present invention, rather than to limit the present invention.

In addition, the terms "first" and "second" are only used to distinguish in the description and have no special meaning.

[0056] The motor is mainly composed of a rotor and a stator. The common rotor core adopts an inserted magnetic steel block structure. A magnetic steel block made of permanent magnet material is inserted into the rotor core as the rotating mechanism of the motor. It interacts with the rotating magnetic field generated by the stator to rotate the rotor and generate the output of the motor. During the magnetic steel assembly process, a magnetic isolation sheet is usually provided between two adjacent magnetic steels to reduce the mutual adsorption between the magnetic steels. In the prior art, the separation process of the magnetic isolation sheet and the magnetic steel insertion process cannot be automated at the same time. Generally, the magnetic steel and the magnetic isolation sheet are manually separated, and then the magnetic steel is introduced into the magnetic steel slot. The mode of manual separation and assembly not only leads to low assembly accuracy and slow assembly speed, but also there may be problems of reverse insertion of magnetic poles due to improper operation of workers during the assembly process.

[0057] Based on this, the present application provides a magnetic steel insertion device, which can also realize the automatic separation of the magnetic isolation sheet and the magnetic steel during the process of inserting the magnetic steel into the corresponding position of the rotor core, and can effectively improve the assembly speed and assembly accuracy. Figures 1 to 12 The magnetic steel insertion device provided in the embodiment of the present application includes a frame 1, a carrier 3, a conveying path, a first loading component 5, a second loading component 4 and a magnetic steel insertion structure 6, wherein the conveying path includes a first conveying path 21, a second conveying path 22 and a return path 23, and the following is combined Figures 1 to 12 Specifically, these mechanisms are used to transport the carrier 3 containing magnetic steel and magnetic isolation sheets, and the return path 23 is used to transport the empty carrier 3; the first loading component 5, the second loading component 4 and the magnetic steel insertion structure 6 are all arranged on the frame 1, and the first loading component 5 is used to insert the opened magnetic steel into the corresponding slot of the rotor core. Therefore, using the magnetic steel insertion equipment provided by the embodiment of the present application, the magnetic steel and the magnetic isolation sheet located on the second conveying path 23 can be transported to the magnetic steel insertion station during the magnetic steel insertion process, and the first loading component 5 can transport the empty carrier 3 to the return path 23, the second loading component 4 is used to lift the rotor core to the magnetic steel insertion station, and the magnetic steel insertion structure 6 is used to separate the magnetic steel and the magnetic isolation sheet loaded to the magnetic steel insertion station, and insert the separated magnetic steel into the corresponding position on the rotor core, so as to realize the automatic separation of the magnetic steel and the magnetic isolation sheet, so that compared with the prior art, the assembly accuracy and assembly speed are effectively improved, and the problem of reverse insertion of magnetic poles due to improper operation of workers will not occur during the assembly process.

[0058] As an example, in the embodiment, as mentioned above, the second conveying path 22 and the return path 23 may include a conveyor belt, for example, the second conveying path 22 and the return path 23 may include two conveyor belts arranged side by side, and the carrier 3 mentioned above may be conveyed by these two conveyor belts; as an example, the first conveying path 21 may include a linear motor, and the second loading assembly 4 is conveyed by the linear motor; as an example, a plurality of slots extending axially are arranged on the rotor core, and the plurality of slots are radially distributed with the axis as the center and are located on the same straight line in pairs, and the plurality of slots all pass through the core, and the rotor core magnet insertion device can insert two magnets into two corresponding slots located on the same straight line at the same time.

[0059] In the embodiment, the carrier 3 needs to be connected and coordinated with multiple structures. To facilitate the subsequent writing and description of the entire technical solution, the structure of the carrier 3 is described here first: Figure 2As shown, the carrier 3 includes a base plate 31 and a magnetic steel clip 32 arranged on the base plate 31, and a plurality of magnetic steels and magnetic isolation sheets are cross-placed in the magnetic steel clip 32, wherein a cover plate 33 is provided at either end of the clip 32, and the cover plate 33 can limit the magnetic steel to prevent the magnetic steel and the magnetic isolation sheets from sliding out of the magnetic steel clip 32 due to inertia during transportation. It should be emphasized that when the carrier 3 is transported through the second conveying path 22, the cover plate 33 is located at the end of the clip 32 away from the magnetic steel structure 6 to avoid interference when the magnetic steel and the magnetic isolation sheets are loaded to the magnetic steel insertion station; at least one magnetic steel clip 32 is provided, and in this embodiment, four magnetic steel clips 32 are provided, and grasping portions 34 are respectively provided on the outer sides of the two magnetic steel clips 32 located at the two ends, so as to facilitate grasping of the carrier 3; a notch is provided at the lower edge of the base plate 31, and the side wall of the notch along the second direction forms a blocking portion 35. As shown Figure 1 As shown in FIG. 1 , the X direction is defined as the first direction, the Y direction is defined as the second direction, and the Z direction is defined as the third direction. In other drawings, some structures are presented at different angles. For the description of these three directions that appear below, please refer to the attached drawings. Figure 1 It is described by the direction in which the structure is placed.

[0060] In the examples, see Figure 1 and Figure 3 As shown, the first conveying path 21 is arranged on the table top of the frame 1, and the second loading component 4 is arranged on the first conveying path 21. The second loading component 4 is transported in the first direction through the first conveying path 21. The second loading component 4 can fix the rotor core and can drive the rotor core to move in the third direction and rotate around its axis. In order to avoid interference between the rotating jacking structure 4 and the second conveying path 22 (the first conveying path 21 and the second conveying path 22 are cross-arranged, which will be further described below when describing the second conveying path 22), and to increase the space utilization rate of the table top of the frame 1, a avoidance groove is provided on the table top of the frame 1. The avoidance groove is located on one side of the first conveying path 21, and the length of the avoidance groove is the same as the length of the first conveying path 21. Part of the structure of the second loading component 4 can extend into the avoidance groove.

[0061] Specifically, the second loading assembly 4 includes a first mounting frame 41, a second mounting frame 42, a lifting structure 43, a rotating drive structure 44 and a positioning module 45. One end of the first mounting frame 41 cooperates with the sliding plate of the first conveying path 21, and the other end can cross the avoidance slot and slide with the linear guide 46. The linear guide 46 is arranged on the table of the frame 1, which can increase the stability of the first mounting frame 41. The fixed end of the lifting structure 43 is arranged on the first mounting frame 41, the second mounting frame 42 is arranged on the driving end of the first lifting structure 43, the rotating drive structure 45 is arranged on the second mounting frame 42, and the positioning module 46 is arranged on the driving end of the rotating drive structure 45. The lifting structure 43 drives the second mounting frame 42, the rotating drive structure 44 and the positioning module 45 to move in the third direction and transport them to the magnetic steel insertion station. The rotating drive structure 44 can drive the positioning module 45 to rotate around its axis to change the position of the slot on the rotor core. As an example, as mentioned above, the first lifting structure 43 may include a linear motor, and the rotary drive structure 45 may include a rotary motor.

[0062] In the examples, see Figure 1 and Figure 4 The second conveying path 22 and the return path 23 are respectively set up on the frame 1 along the first direction, and both are arranged to cross the first conveying path 21, and the first conveying path 21 is located below the two. An empty carrier 3 is placed on the return path 23, and a carrier 3 equipped with magnetic steel and magnetic isolation sheet is set on the second conveying path 22. The second conveying path 22 and the return path 23 respectively include two, and the two second conveying paths 22 are symmetrically distributed on the frame 1 relative to the magnetic steel structure 6, and the return paths 23 are also symmetrically distributed on the frame 1 relative to the magnetic steel structure 6. The two return paths 23 are respectively located on the side of the second conveying path 22 away from the magnetic steel structure 6.

[0063] As an example, a sensor is provided on the line support frame of the conveyor belt on either side of the second conveying path 22, and the sensor includes a magnetic pole sensor 221 and a photoelectric sensor 225 (a group of magnetic pole sensors 221 and multiple groups of photoelectric sensors 225 are provided on the second conveying path 22, wherein the photoelectric sensors 225 are provided at the adjacent Figure 4Only one group is marked), the magnetic pole sensor 221 detects the positive and negative poles of the magnetic steel, and an alarm will be prompted when the magnetic steel is reversed (the alarm is not shown in the figure), which can avoid the situation where the magnetic steel is reversed, and the photoelectric sensor 225 can sense the position of the carrier 3, which is conducive to the precise blocking of the positioning member 222 or the precise clamping and loading of the first feeding component 5 that will appear in the subsequent description. Specifically, the magnetic pole sensor 221 is provided with one, and the mounting plate for installing the magnetic pole sensor 221 is located on the outside of the line support frame and is higher than the height of the carrier 3 located on the second conveying path 22. The photoelectric sensor is provided with no less than one group, and the mounting plate for installing the photoelectric sensor is lower than the support surface located on the second conveying path 22. When the carrier 3 is located on the second return line, the photoelectric sensor is located below the carrier 3. While sensing the position of the carrier 3, it will not interfere with the transportation of the carrier 3.

[0064] Furthermore, the second conveying path 22 further includes a positioning member 222, which blocks the carrier 3 so that the carrier 3 at the second position in the conveying direction is positioned at one place and does not continue to be conveyed, so that the first carrier 3 to be clamped is separated from the carrier 3 at the second position, thereby preventing the first loading component 5 from interfering with the clamping of the first carrier 3. For the convenience of description, we define the carrier 3 at the front side of the conveying direction on the second conveying path 22 as the first carrier 3, and the carrier 3 adjacent to it as the second carrier 3. After the first carrier 3 is clamped, the second carrier 3 becomes the first carrier 3 in sequence.

[0065] As an example, the positioning member 222 can be a blocking cylinder, which can be arranged below the second conveying path 22. When the piston rod of the blocking cylinder is extended, the piston rod extends from between two parallel conveying belts of the second conveying path 22, and the extended end abuts against the blocking part 35, thereby realizing the positioning of the carrier 3.

[0066] As an example, the second conveying path 22 also includes a non-return component 223 and a positioning plate 224, which are respectively located on the inner side of the line support frame of the second conveying path 22 (the non-return component 223 is a conventional technical structure in the field, and its specific structure and principle are not described here), and the positioning plate 224 is higher than the conveying surface of the second conveying path 22. The distance between the non-return component 223 and the positioning plate 224 is consistent with the length of the carrier 3 along the conveying direction. The positioning plate 224 is used to prevent the carrier 3 from continuing to be transported along the second conveying path 22, and the non-return component 223 is used to prevent the carrier 3 from rebounding after hitting the positioning plate 224.

[0067] Specifically, the blocking portion 35 on the front side of the carrier 3 abuts against the positioning plate 224, and the rear side of the carrier 3 abuts against the non-return assembly 223. The positioning plate 224 and the non-return assembly 223 cooperate to achieve the positioning of the carrier 3, so that the carrier 3 is accurately docked at the loading position on the second conveying path 22 (the clamping position of the first loading assembly 5 for the carrier 3 is defined as the loading position), so that the first loading assembly 5 can accurately grasp the carrier 3.

[0068] In summary, the carrier 3 equipped with the magnetic steel and the magnetic isolation sheet is sequentially loaded onto the second conveying path 22, and the carrier 3 at the first position passes through the positioning member 222 and the non-return assembly 223 in sequence and is blocked by the positioning plate 224. The non-return assembly 223 can prevent the carrier 3 from hitting the positioning plate 224 and rebounding, and stops at the loading position waiting to be clamped by the first loading assembly 5 (grabbed by the grasping structure 51 of the first loading assembly 5, which is described below), and the carrier 3 at the second position is blocked by the positioning member 222, so that the carrier 3 at the first position and the carrier 3 at the second position are not in contact with each other. A gap is created between the two carriers 3 (it should be emphasized that there is a gap between the non-return component 223 and the positioning member 222, and the size of the gap is limited to a size that does not interfere with the grasping structure 51). After the carrier 3 in the first position on the second conveying path 22 is grasped, the positioning member 222 releases the carrier 3 in the second position (which becomes the carrier 3 in the first position at this time), and the non-return component 223 and the positioning plate 224 position it, and the adjacent carrier 3 (which becomes the carrier 3 in the second position at this time) is blocked by the positioning member 222.

[0069] In the embodiment, the first loading assembly 5 includes a grabbing structure 51 (the grabbing structure 51 here refers to grabbing the target object and transporting it to a specified position), a guide channel 52, a magnetic steel pushing structure 53 and a gantry 54. The gantry 54 is arranged on the frame 1, and the guide channel 52 is arranged on the workbench 61 for positioning the magnetic steel and the magnetic isolation sheet. The grabbing structure 51 and the magnetic steel pushing structure 53 are arranged on the gantry 54. The grabbing structure 51 is used to grab the carrier 3 carrying the magnetic steel and the magnetic isolation sheet from the second conveying path 22 to the guide channel 52, so that the opening of any clip 32 is aligned with the guide channel. At the entrance of the channel 52, the magnetic steel pushing structure 53 is used to push all the magnetic steels and magnetic isolation sheets in one of the clips 32 on the carrier 3 to the magnetic steel insertion station, and the grasping structure 51 drives the carrier 3 to change its position to align the opening of the other clip 32 equipped with magnetic steels and magnetic isolation sheets with the guide channel 52 until there is no product on the carrier 3. At this time, the grasping structure 51 puts the empty carrier 3 back to the return path 23, and then clamps the carrier 3 in the first position from the second conveying path 22. In this process, the position of the carrier 3 and the position of the magnetic steel are sensed using a photoelectric sensor (not shown in the figure).

[0070] As an example, Figure 6As shown, the gripping structure 51 includes a three-axis transplanting module 511 (a conventional technical means adopted in this field, which will not be described here), a clamping claw cylinder 513 and a clamping block 512. The clamping claw cylinder 513 drives the clamping block 512 to move closer or farther to achieve the gripping of the carrier 3. The clamping block 512 cooperates with the gripping portion 34 of the carrier 3. The three-axis transplanting module 511 drives the clamping claw cylinder 513 and the clamping block 512 to move in the first direction, the second direction and the third direction; Figure 7 As shown, the magnetic steel pushing structure 53 includes a mounting back plate 531, a transverse movement module 532 and a push plate 533. The mounting back plate 531 is arranged on the gantry 54, and the transverse movement module 532 is arranged on the mounting back plate 531. The transverse movement module 532 may include, for example, a rodless cylinder, and the push plate 533 is arranged at the driving end of the rodless cylinder. In the example, a sensor, such as a photoelectric sensor, may also be provided on the mounting back plate 531 for sensing the position of the magnetic steel.

[0071] In the embodiments, see Figure 1 and Figure 8 The magnetic steel structure 6 includes a workbench 61, a first guide member 62, an iron core positioning structure, a magnetic steel member 64 and a magnetic isolation sheet separation structure. The workbench 61 is mounted on the frame 1 and is located between the two second conveying paths 22 (it is recorded above: the two second conveying paths 22 are symmetrically distributed on the frame 1 relative to the magnetic steel structure 6). The first conveying path 21 passes under the workbench 61, and the first guide member 62 runs through the workbench 61. The first guide member 62 is used to accurately position the magnetic steel. The iron core positioning structure is used to position the rotor core so that the slot of the rotor core corresponds to the magnetic steel flow channel of the first guide member 62. The magnetic steel member 64 is used to insert the magnetic steel into the slot. The magnetic isolation sheet separation structure is used to separate the magnetic isolation sheet from the magnetic steel. The separation of the magnetic isolation sheet is completed during the action of inserting the magnetic steel. The structure is compact and the work efficiency can be effectively improved.

The first flow channel 621 2 can accommodate a magnet and a magnetic isolation plate to pass through at the same time, the magnetic steel structure 53 is pushed to push the magnet and the magnetic isolation plate from the clip 32 into the guide channel 52, and then continue to push them to the positioning channel 6211, and continue forward to the top of the first channel, and the magnetic steel member 64 is inserted to apply a downward thrust to it to push it out of the first channel 6212 (due to the adsorption force between the magnets and the blessing of the speed, the frontmost magnet will not produce free fall motion due to gravity, and the magnetic steel member 64 needs to be inserted to apply a downward thrust to it); the second part 622 is a plate-like structure, connected to the first part 621 (located in the middle of the two first channels 6212) and passes through the table top of the workbench 61.

[0073] Preferably, the core positioning structure may include a long through hole 6213 opened along the third direction of the first guide member 62, the long through hole 6213 passes through the first part 621 and the second part 622, and a blocking ring plate 6214 is provided in the cavity of the long through hole 6213. Based on the structure of the rotating shaft of the rotor core, the upper end portion of the rotating shaft extends into the cavity above the blocking ring plate 6214 and partially rests on the blocking ring plate 6214, thereby positioning the rotor core.

[0074] Furthermore, the magnetic steel structure further includes a buffer component to buffer the impact of the rotating shaft on the blocking ring plate 6214 and protect the rotating shaft of the rotor core from being damaged by the impact.

The first push rod 6441 is used to push the magnetic steel down, and the second push rod 6442 is used to push the magnetic isolation plate down. The above-mentioned length restriction is imposed so that the magnetic isolation plate will be pushed down, and also to cooperate with the separation work of the magnetic isolation plate.

[0077] In an embodiment, two groups of magnetic isolation sheet separation structures are provided, which are respectively arranged on both sides of the second part 622 of the first guide member 62, and are centrally symmetrically distributed in the third direction relative to the first guide member 62. Any magnetic isolation sheet separation structure may include a second guide member 651, a blowing structure 652 and a magnetic steel block 653. The second guide member 651 includes a diversion port, and the blowing structure 652 and the magnetic steel block 653 are arranged at the diversion port. The magnetic steel and the magnetic isolation sheet are separated at the diversion port, and the magnetic steel is inserted into the slot along the second flow channel (not shown in the figure), and the magnetic isolation sheet flies out of the second flow channel (not shown in the figure).

[0078] Specifically, the second guide member 651 is provided with a second flow channel (not shown in the figure), the second flow channel is connected to the first flow channel 6212, the diversion port is provided at a position of the second flow channel close to the first guide member 651, the diversion port can accommodate the magnetic isolation plate to enter and exit, a slope 6511 is provided at the lower bottom position of the diversion port, a magnetic steel block 653 is embedded on the side of the second flow channel corresponding to the diversion port, the magnetic steel block 653 can be adsorbed with the magnetic steel, a through hole is provided on the magnetic steel block 653, a blowing structure 652 is provided on the outside of the second guide member 651, the air outlet of the blowing structure 652 is aligned with the through hole, the wind blown out by the blowing structure 652 can pass through the through hole and the ventilation hole 6443 and blow onto the magnetic isolation plate, the magnetic steel block 653 prevents the magnetic steel from being offset under the action of wind, but can blow the magnetic isolation plate out of the second flow channel along the diversion port, and slide into the collecting flow channel 66 along the slope 6511, thereby completing the separation of the magnetic isolation plate and the magnetic steel.

[0079] Furthermore, the collecting channel 66 is arranged below the workbench 61, and may include a receiving portion 661 and a guiding portion 662. The head of the receiving portion 661 is provided with a avoiding notch, and the second guide member 651 is arranged in the space formed by the avoiding notch. The receiving portion 661 forms a semi-enclosed posture for the two second guide members 651, and the two side walls of the avoiding notch are respectively provided with a feeding port, which can respectively correspond to the diversion port and extend downward to cover the slope 6511, so that the magnetic isolation sheet sliding down the slope 6511 can enter the cavity of the receiving portion 661.

[0080] Furthermore, in order to prevent the magnetic isolation sheet from accumulating in the cavity of the receiving portion 661, the bottom edge of the receiving portion 661 is set to a slope structure, and the cross-section of the receiving portion 661 in the first direction is a right-angled trapezoidal structure. The magnetic isolation sheet can slide from the receiving portion 661 to the guide portion 662, and then be discharged from the discharge port of the guide portion 662.

[0081] Preferably, the collecting channel 66 may further include a blocking sheet 663 , which is disposed on a side of the second guide member 651 away from the first guide member 62 , and is used to prevent the magnetic isolation sheet from flying out to both sides.
