Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of permanent magnet motors, in particular to a rotor core magnetic steel inserting device. BACKGROUND

[0002] The rotor of a permanent magnet motor includes a rotor core and magnetic steel. According to the position of the magnetic steel mounted on the rotor core, the rotor can be divided into a surface-mounted rotor and an interior-mounted rotor, wherein the surface-mounted rotor refers to the magnetic steel adhering to the outer circumferential surface or the inner circumferential surface of the rotor core; the interior-mounted rotor refers to the magnetic steel inserted into the magnetic steel slot inside the rotor core.

[0003] For the interior-mounted rotor, in the process of inserting the magnetic steel, the rotor core needs to be glued in the magnetic steel slot first, and then the magnetic steel is inserted into the magnetic steel slot. There is a rotor core magnetic steel inserting device in the prior art, which can automatically glue and insert magnetic steel for the rotor core. Generally, the rotor core magnetic steel inserting device includes a turntable, a plurality of rotor core storage devices arranged on the turntable, and a plurality of mechanical hands arranged around the turntable. The rotor core magnetic steel inserting device has a plurality of stations, and each station is provided with a rotor core storage device. In different stations, the mechanical hand can perform one of the functions of feeding, gluing, inserting, and discharging.

[0004] The motion trajectory of the mechanical hand is relatively fixed. In order to correctly glue and insert the magnetic steel for the rotor core placed in the rotor core storage device, it is necessary to ensure that the rotor core is in the correct posture in the rotor core storage device. For this purpose, the rotor core jig of the rotor core storage device is rotatably arranged on the turntable and is connected with a rotating device (such as a motor) for driving the rotation thereof, so as to adjust the posture of the rotor core. However, this requires the installation of a rotating device on each rotor core storage device, which is relatively high in cost. UTILITY MODEL CONTENT

[0044] The technical solutions of the present application will be further described below in conjunction with the drawings and through specific embodiments. It can be understood that the specific embodiments described herein are only used to explain the present application, but not to limit the present application. In addition, it should be noted that, for the convenience of description, only the parts related to the present application are shown in the drawings, but not all.

[0045] Some orientation words are defined in the present application, and the orientation words such as "upper", "lower", "left", "right", "inner", "outer" are used for the convenience of understanding, and thus do not constitute a limitation on the scope of protection of the present application, unless the contrary is stated.

[0046] In the present application, unless explicitly specified and limited, "on" or "under" of the first feature to the second feature can include that the first and second features are in direct contact, or that the first and second features are not in direct contact but are in contact through another feature between them. Moreover, "on", "above" and "over" of the first feature to the second feature includes that the first feature is directly above and obliquely above the second feature, or only indicates that the first feature is higher in horizontal height than the second feature. "Under", "below" and "under" of the first feature to the second feature includes that the first feature is directly below and obliquely below the second feature, or only indicates that the first feature is lower in horizontal height than the second feature.

[0047] In the description of the present application, unless explicitly specified and limited, the terms "connected", "connected", "fixed" should be understood broadly, for example, it can be fixedly connected, or it can be detachably connected, or it can be integrated; it can be mechanically connected, or it can be electrically connected; it can be directly connected, or it can be indirectly connected through an intermediate medium; it can be the internal communication of two elements or the interaction relationship between two elements. 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.

[0048] As shown in Figure 1 The rotor core 10 includes a plurality of magnetic steel grooves 11, which are uniformly arranged in the circumferential direction. The upper end of the magnetic steel groove 11 is provided with an opening to facilitate the insertion of the magnetic steel (not shown) into the magnetic steel groove 11. The magnetic steel groove 11 extends downward along the axis direction as a whole, and the lower end of the magnetic steel groove 11 is located at or near the lower end of the rotor core 10. The number of magnetic steel grooves 11 can be 4, 6, 12, etc.

[0049] Figure 2 Only part of the structure of the magnetic steel inserting device of the rotor core is shown in the present application, not all the structures. Specifically, Figure 2 The feeding manipulator, the discharging manipulator, the dispensing manipulator, the magnetic steel inserting manipulator, the image acquisition device for detection, etc. are omitted in the present application. It can be understood that the above manipulators and image acquisition devices can adopt any structure known in the prior art, and the embodiments of the present application are not limited.

[0050] The rotor core magnet insertion equipment can have multiple workstations. In one possible implementation, the multiple workstations include a loading station, a glue dispensing station, a magnet insertion station, and a blanking station. The loading station is used to load the rotor core 10. The glue dispensing station is used to dispense glue on the rotor core 10. The magnet insertion station is used to insert magnets into the rotor core 10. The blanking station is used to remove the rotor core 10 after magnetization.

[0051] The plurality of workstations may be arranged in sequence along the circumferential direction, for example, in the order of a loading station, a glue dispensing station, a magnet insertion station and a unloading station.

[0052] Optionally, the multiple workstations may further include one or more detection workstations, and the detection workstations may be interspersed among the multiple workstations.

[0053] Specifically, the multiple workstations may include a loading station, a pressing station, a first inspection station, a glue dispensing station, a second inspection station, a magnet insertion station, a third inspection station, and an unloading station. The pressing station is used to press the rotor core 10 into a preset position. The first inspection station is used to detect whether the rotor core 10 is in the preset position. The second inspection station is used to detect the quality of the glue dispensing. The third inspection station is used to detect the quality of the magnet insertion.

[0054] It should be noted that, in the loading station, the posture of the rotor core 10 after loading may not be the preset posture, which will affect the subsequent dispensing and magnetization of the magnetic steel slots 11 of the rotor core 10 .

[0055] To this end, in some workstations, the posture of the rotor core 10 needs to be adjusted, for example, the rotor core 10 needs to be rotated by a certain angle.

[0056] For example, in the glue dispensing station, the rotor core 10 needs to be rotated to a preset angle to ensure proper glue dispensing in each magnetic steel slot 11. Furthermore, in the magnet insertion station, the rotor core 10 may also need to be rotated to a preset angle to ensure magnet insertion in each magnetic steel slot 11. Furthermore, when the multiple stations include an inspection station, the posture of the rotor core 10 can also be adjusted in, for example, the first inspection station.

[0057] In the embodiment of the present application, the station where the posture of the rotor core 10 needs to be adjusted is defined as a posture adjustment station. As mentioned above, the posture adjustment station includes but is not limited to a first detection station, a glue dispensing station and a magnet insertion station.

[0058] like Figure 2 As shown, the rotor core magnetic steel inserting equipment includes a turntable 20 and a plurality of rotor core storage devices 30 fixedly arranged on the turntable 20 .

[0059] Specifically, the rotating disc 20 can rotate in a horizontal plane, for example, the rotating disc 20 can be arranged on a cam divider (not shown), so that the rotating disc 20 can rotate according to a preset rotation angle.

[0060] With the rotation of the rotating disc 20, the plurality of rotor core storage devices 30 rotate synchronously, and when the rotating disc 20 stops rotating, the plurality of rotor core storage devices 30 correspond to the plurality of stations one by one, that is, one rotor core storage device 30 is arranged in each station. Specifically, one rotor core storage device 30 is arranged in the posture adjusting station.

[0061] That is, the rotor core storage device 30 can enter or exit the posture adjusting station by means of the rotation of the rotating disc 20.

[0062] The rotor core storage device 30 is used to store the rotor core 10. In the embodiment of the present application, when the rotor core 10 is placed in the rotor core storage device 30, the axis of the rotor core 10 is arranged longitudinally, and the opening of the magnetic steel slot 11 faces upward, so as to facilitate dispensing and inserting the magnetic steel into the magnetic steel slot 11.

[0063] As shown in Figure 3 and Figure 4 , the rotor core storage device 30 comprises a fixed seat 31, the fixed seat 31 is fixedly arranged on the rotating disc 20, the fixed seat 31 has a center hole 311 longitudinally penetrating, a rotating shaft 32 is arranged in the center hole 311, and the rotating shaft 32 can rotate in the center hole 311. The upper end of the rotating shaft 32 is provided with a rotor core jig 33 for storing the rotor core 10, and the rotor core jig 33 can be arranged above the rotating disc 20, so as to facilitate placing the rotor core 10 into the rotor core jig 33 and dispensing and inserting the magnetic steel into the rotor core 10. In addition, the rotor core jig 33 rotates synchronously with the rotating shaft 32, that is, when the rotating shaft 32 rotates, the rotor core jig 33 rotates correspondingly.

[0064] Figure 6 A sectional view at A-A in Figure 5 is shown, as shown in Figure 6 , as an example of the rotating connection between the fixed seat 31 and the rotating shaft 32, the rotor core storage device 30 further comprises a bearing 34, the center hole 311 of the fixed seat 31 is provided with a bearing mounting groove 312, the bearing 34 is arranged in the bearing mounting groove 312, and the rotating shaft 32 is arranged in the bearing 34.

[0065] It should be noted that the number of bearings 34 can be one or more. In the embodiment of the present application, the number of bearings 34 is two, and the two bearings 34 are arranged in sequence in the axial direction.

[0066] As shown in Figure 6As shown, in order to limit the bearing 34 located below, the lower surface of the outer ring of the bearing 34 abuts against the bottom wall of the bearing mounting groove 312, and the lower surface of the inner ring of the bearing 34 abuts against the lower bearing limiting block 341, which is fixedly arranged with the rotating shaft 32.

[0067] As shown in the figure, Figure 6 As shown, in order to limit the bearing 34 located above, the upper surface of the inner ring of the bearing 34 abuts against the step 321 of the rotating shaft 32, and the upper surface of the outer ring of the bearing 34 abuts against the upper bearing limiting plate 342, which is fixedly arranged on the upper surface of the fixed seat 31.

[0068] As shown in the figure, Figure 4 and Figure 6 As shown, the rotor core jig 33 includes a storage groove 331, which has a circular arc surface matched with the outer diameter of the rotor core 10. When the rotor core 10 is placed in the storage groove 331, the rotor core 10 is limited by the storage groove 331 and remains in a vertical state.

[0069] As shown in the figure, Figure 4 and Figure 6 As shown, the rotating shaft 32 is further provided with a driven wheel 35, which can rotate synchronously with the rotating shaft 32. For example, the driven wheel 35 and the rotating shaft 32 can be fixedly connected with each other through a key connection, or can be fixedly connected with each other through an interference fit. The driven wheel 35 is used to be connected with a rotating device 40 capable of driving the driven wheel 35 to rotate, so as to drive the rotating shaft 32 to rotate, and further drive the rotor core jig 33 to rotate, so as to adjust the posture of the rotor core 10. The specific structure of the rotating device 40 will be described below.

[0070] In the embodiment of the present application, the driven wheel 35 can be arranged at the lower end of the rotating shaft 32, especially below the turntable 20, so as to avoid occupying the space above the turntable 20.

[0071] As shown in the figure, Figure 2 As shown, the rotor core magnet inserting device further includes a rotating device 40, which is arranged in the posture adjusting station. The rotating device 40 is used to rotate the rotor core jig 33 located in the posture adjusting station, so as to adjust the posture of the rotor core 10 in the posture adjusting station. Specifically, the rotating device 40 can drive the driven wheel 35 to rotate, so as to synchronously rotate the rotating shaft 32 and the rotor core jig 33, and further adjust the posture of the rotor core 10.

[0072] As shown in the figure, Figure 7 As shown, the rotating device 40 includes a driving wheel 41, a rotating assembly 42 for driving the driving wheel 41 to rotate, and a moving assembly 43 for driving the driving wheel 41 to move.

[0073] It should be noted that the number of driving wheels 41 can be one or more.

[0074] As an example, in Figure 7 , the number of driving wheels 41 is two, the two driving wheels 41 are arranged at intervals and at the same height, so as to form a connection area between the two driving wheels 41, the driven wheel 35 can enter the connection area to facilitate contact with the two driving wheels 41 at the same time, and then the driven wheel 35 can be driven to rotate by the driving wheels 41.

[0075] As Figure 7 indicated, as an example of the rotating assembly 42, the rotating assembly 42 includes a motor 421, a first pulley 422, a second pulley 423 and a belt 424. The output shaft of the motor 421 is connected with the first pulley 422 to drive the first pulley 422 to rotate. The first pulley 422 and the second pulley 423 are connected by the belt 424, so that the first pulley 422 can drive the second pulley 423 to rotate. The driving wheel 41 in the foregoing can be arranged on the second pulley 423.

[0076] It should be noted that the number of second pulleys 423 can be one or more, and in particular, the number of second pulleys 423 corresponds to the number of driving wheels 41. In Figure 7 , the number of second pulleys 423 is two, and one driving wheel 41 is arranged on each second pulley 423.

[0077] As Figure 7 indicated, as an example of the moving assembly 43, the moving assembly 43 includes a base 431, a cylinder 432 and a sliding plate 433. The base 431 is fixedly arranged, the cylinder 432 is fixedly arranged on the base 431, and the sliding plate 433 is slidingly arranged on the base 431 and connected to the execution end of the cylinder 432. The cylinder 432 can drive the sliding plate 433 to slide on the base 431. The rotating assembly 42 in the foregoing is arranged on the sliding plate 433, and when the sliding plate 433 slides on the base 431, the rotating assembly 42 moves synchronously.

[0078] As Figure 7 indicated, as an example, the sliding plate 433 and the base 431 can be slidingly connected through a sliding block and a sliding rail. Specifically, the sliding rail is fixedly arranged on the base 431, and the sliding block is fixedly arranged on the sliding plate 433, so that the sliding plate 433 and the base 431 can slide relative to each other.

[0079] As Figure 7 indicated, in the embodiment, the sliding rail is a straight sliding rail, and the sliding rail extends along the horizontal direction, so that the sliding plate 433 can move linearly in the horizontal plane to drive the driving wheel 41 to move linearly in the horizontal plane.

[0080] Specifically, due to the sliding of the sliding plate 433, the driving wheel 41 has a first position and a second position in the horizontal plane, when the driving wheel 41 is in the first position, the driving wheel 41 is in contact with the driven wheel 35, so that the driving wheel 41 can drive the driven wheel 35 to rotate; when the driving wheel 41 is in the second position, the driving wheel 41 is separated from the driven wheel 35, so that the driving wheel 41 cannot drive the driven wheel 35 to rotate.

[0081] In addition, when the driving wheel 41 is in the second position, there is no interference between the driving wheel 41 and the driven wheel 35, so that the driven wheel 35 can move to the next station with the rotation of the turntable 20 without being blocked by the driving wheel 41. That is, when the driving wheel 41 is in the second position, the driving wheel 41 is located outside the moving track of the driven wheel 35.

[0082] As mentioned above, in the embodiment of the present application, the air cylinder 432 can drive the driving wheel 41 to reciprocate along the straight line segment in the horizontal plane, when the driving wheel 41 is in the first position, there is a horizontal interaction force between the driving wheel 41 and the driven wheel 35, which ensures that there is enough friction between the driving wheel 41 and the driven wheel 35, so that the driving wheel 41 can drive the driven wheel 35 to rotate.

[0083] It should be noted that the air cylinder 432 can be replaced by other components, such as a gear and rack assembly, a screw assembly, etc. Components that can be driven by a motor to reciprocate linearly.

[0084] In order to avoid the rotation of the rotating shaft 32 at will, for example, to avoid the rotation of the rotating shaft 32 during the rotation of the turntable 20, the rotation of the rotating shaft 32 can be limited.

[0085] Therefore, as shown in Figure 3 and Figure 4 The rotor core storage device 30 further comprises a sliding ring 36 and a control clamp 37. The sliding ring 36 is sleeved on the rotating shaft 32, for example, the sliding ring 36 is sleeved on the middle part of the rotating shaft 32, located between the driven wheel 35 and the rotor core jig 33, especially can be sleeved between the driven wheel 35 and the lower bearing limiting block 341. The control clamp 37 can drive the sliding ring 36 to slide on the rotating shaft 32 along the axial direction.

[0086] Specifically, as shown in Figure 8As shown, the rotating shaft 32 comprises a first shaft segment 322 and a second shaft segment 323, the first shaft segment 322 can be located above the second shaft segment 323, the diameter of the first shaft segment 322 is larger than that of the second shaft segment 323, and an axially extending limiting groove 3221 is arranged on the outer circumferential surface of the first shaft segment 322. The inner diameter of the sliding ring 36 is matched with the diameter of the first shaft segment 322, and a limiting protrusion 361 corresponding to the limiting groove 3221 is arranged on the inner circumferential surface of the sliding ring 36. When the sliding ring 36 is located on the first shaft segment 322, the limiting protrusion 361 is located in the limiting groove 3221, and the sliding ring 36 and the rotating shaft 32 are locked in the circumferential direction and cannot rotate relative to each other; when the sliding ring 36 is located on the second shaft segment 323, since the inner diameter of the sliding ring 36 is larger than the diameter of the second shaft segment 323, the sliding ring 36 and the rotating shaft 32 are unlocked relative to each other and can rotate relative to each other.

[0087] The control clamp 37 is used to drive the sliding ring 36 to move back and forth between the first shaft segment 322 and the second shaft segment 323. Specifically, as shown in Figure 4 the outer circumferential surface of the sliding ring 36 is provided with a circumferentially extending clamping groove 362, and the control clamp 37 comprises at least one clamping pin 371 (for example, two oppositely arranged clamping pins 371), the clamping pin 371 is arranged in the clamping groove 362, and the clamping pin 371 and the clamping groove 362 abut each other, so that there is a friction force between the clamping pin 371 and the clamping groove 362.

[0088] Thus, as shown in a of Figure 9 when the sliding ring 36 is located on the first shaft segment 322, since the rotating shaft 32 and the sliding ring 36 are locked relative to each other, if the rotating shaft 32 is to be rotated, the friction force between the clamping pin 371 and the clamping groove 362 needs to be overcome. As shown in b of Figure 9 when the sliding ring 36 is located on the second shaft segment 323, since the rotating shaft 32 and the sliding ring 36 are unlocked relative to each other, the friction force between the clamping pin 371 and the clamping groove 362 does not need to be overcome. As can be seen, by arranging the control clamp 37 and the sliding ring 36, the required force for rotating the rotating shaft 32 can be increased when necessary, thereby ensuring that the rotating shaft 32 cannot be rotated at will.

[0089] As shown in Figure 4 the axis of the clamping pin 371 can extend in the horizontal direction, and the clamping pin 371 is rotatably arranged on the control clamp 37 along its own axis.

[0090] As shown in Figure 4As shown, the rotor core storage device 30 can further include an elastic element 38 (e.g. a spring), which can be arranged between the sliding ring 36 and the driven wheel 35, or between the sliding ring 36 and the lower bearing limiting block 341. The elastic element 38 can exert an elastic force on the sliding ring 36 to keep the sliding ring 36 in a certain position. For example, when the elastic element 38 is arranged between the sliding ring 36 and the driven wheel 35, the elastic element 38 can exert an upward elastic force on the sliding ring 36 to keep the sliding ring 36 in the first shaft section 322, i.e. in the normal state, the shaft 32 needs to overcome a larger frictional force to rotate when the posture of the rotor core 10 does not need to be adjusted.

[0091] As shown, Figure 4 the rotor core storage device 30 can further include a fixed element 39 fixedly arranged on the shaft 32, for example, the fixed element 39 can be arranged between the driven wheel 35 and the elastic element 38, i.e. the lower end of the elastic element 38 abuts against the fixed element 39, and the upper end of the elastic element 38 abuts against the sliding ring 36.

[0092] In order to drive the control clamp 37 to move the sliding ring 36, as shown in Figure 2 and Figure 10 in the posture adjustment station, the rotor core magnet inserting device further includes a driving device 50 configured to drive the clamping pin 371 of the control clamp 37 to move up and down.

[0093] Specifically, in the embodiment of the present application, the middle part of the control clamp 37 is rotatably arranged on the mounting seat 372, and the mounting seat 372 is fixedly arranged on the lower surface of the turntable 20, so that when one end of the control clamp 37 moves upward, the other end moves downward. For example, in Figure 10 when the right end (i.e. the control end) of the control clamp 37 moves upward, the left end (i.e. the driving end) of the control clamp 37 moves downward, and vice versa.

[0094] The execution end of the driving device 50 is arranged below the driving end of the control clamp 37 and can move up and down, so that when the execution end of the driving device 50 moves upward, the control end of the control clamp 37 can be driven to move downward, so that the sliding ring 36 and the shaft 32 are unlocked. When the execution end of the driving device 50 moves downward, the sliding ring 36 moves upward under the action of the elastic element 38, so that the control end of the control clamp 37 moves upward, and the driving end of the control clamp 37 moves downward.

[0095] As an example, the driving device 50 can be a pneumatic cylinder.

[0096] The use process of the rotor core magnet inserting device according to the embodiment of the present application is as follows:

[0097] The rotating disc 20 rotates to move the rotor core storage device 30 to the posture adjusting station;

[0098] The moving assembly 43 drives the driving wheel 41 to move to the first position to make the driving wheel 41 contact with the driven wheel 35;

[0099] The rotating assembly 42 drives the driving wheel 41 to rotate to make the driving wheel 41 drive the driven wheel 35 to rotate, the driven wheel 35 drives the rotating shaft 32 to rotate, and the rotating shaft 32 drives the rotor core jig 33 to rotate, so as to adjust the posture of the rotor core 10;

[0100] The rotating assembly 42 stops rotating;

[0101] The moving assembly 43 drives the driving wheel to move to the second position to make the driving wheel 41 separate from the driven wheel 35 and the moving track of the driving wheel 41 not interfere with the moving track of the driven wheel 35;

[0102] The rotating disc 20 rotates to move the rotor core storage device 30 to the next station.

[0103] Although the present application has been described in detail with general description, specific embodiments and experiments, some modifications or improvements can be made on the basis of the present application, which is obvious to those skilled in the art. Therefore, these modifications or improvements made on the basis of not deviating from the spirit of the present application shall fall within the scope of the present application.
