Description

Technical Field

[0001] The present application relates to the field of motor technology, and in particular to a pasting assembly, a magnetic steel pasting device, and a magnetic steel pasting method. Background Art

[0002] A motor rotor typically consists of an iron core and magnets attached to its outer circumference. Currently, the magnets are typically attached manually, which involves applying glue to the magnets and an activator to the core. The magnets are then placed close to the core. Due to the strong magnetic induction between the magnets and the core, the magnets quickly attach to the core as they approach, making it difficult to precisely control the placement of the magnets.

[0003] The inventors of this application have found in the long-term research process that in order to stick the magnetic steel to the desired position, the following methods are usually used. Figure 1 Specifically, the method shown is to first attach the edge of the magnet 30 to the edge of the iron core 32, and then push the magnet 30 into the desired position. Although this method can better control the position of the magnet 30, it can cause some glue to be squeezed out, resulting in insufficient bonding strength between the iron core 32 and the magnet 30, thereby affecting motor performance. Summary of the Invention

[0006] In order to solve the above technical problems, another technical solution adopted in this application is: to provide a magnetic steel pasting device, which includes the pasting component, rotating shaft and base described in any of the above embodiments; wherein, the pasting component is gap-mounted on the periphery of the rotating shaft, and the rotating shaft is used to pass through the through hole in the axial direction of the iron core, so that the iron core is sleeved on the rotating shaft to fix and rotate the iron core; the base includes a first abutting portion and a second abutting portion arranged opposite to each other, and the first abutting portion and the second abutting portion are respectively used to abut against the two ends of the rotating shaft to fix the position of the rotating shaft.

[0007] In order to solve the above technical problems, another technical solution adopted in the present application is: to provide a magnetic steel pasting method, the magnetic steel pasting method comprising: passing the rotating shaft through the through hole in the axial direction of the iron core and fixedly connected to the iron core, wherein the outer peripheral surface of the iron core is provided with a plurality of magnetic steel installation positions; the pasting component is gap-sleeved on the periphery of the rotating shaft; wherein the pasting component comprises a positioning plate, a guide rail and a movable part, the positioning plate is fixedly provided on one side of the iron core; the guide rail is fixedly provided on the positioning plate and has a first extension direction; the movable part is movably provided on the guide rail and can move along the first extension direction; the movable part has The support surface and the hollow area enclosed by the support surface, the movable part corresponds to the position of one of the magnetic steel installation positions; the two ends of the rotating shaft are respectively pressed against the first supporting part and the second supporting part arranged opposite to each other on the base; when the movable part moves to the first position along the first extension direction, the magnetic steel is placed on the support surface of the movable part, wherein the side of the magnetic steel facing the magnetic steel installation position is coated with activator / glue, and the magnetic steel installation position is coated with glue / activator; when the movable part is moved to the second position along the first extension direction, the magnetic steel is detached from the support surface to be adhered to the surface of the iron core.

[0008] The beneficial effects of the present application are as follows: Different from the prior art, the adhesive assembly provided by the present application includes a positioning plate, a guide rail and a movable part, wherein the guide rail is fixedly arranged on the positioning plate and has a first extension direction, the movable part is movably arranged on the guide rail and can move along the first extension direction; the movable part has a support surface and a hollow area surrounded by the support surface, so that a surface of the iron core is exposed through the hollow area, and the magnet is placed through the support surface; when the movable part moves to a first position along the first extension direction, the magnet is placed on the support surface of the movable part; when the movable part moves to a second position along the first extension direction, the magnet is detached from the support surface to be attached to the surface of the iron core.

[0021] The following will be combined with the accompanying drawings in the embodiments of this application to clearly and completely describe the technical solutions in the embodiments of this application. Obviously, the embodiments described are only part of the embodiments of this application, not all of them. Based on the embodiments of this application, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of this application.

[0022] Please refer again Figure 1 The iron core 32 and the magnet 30 to be attached to the surface of the iron core 32 are generally formed by stacking multiple silicon steel sheets. The magnet 30 is a permanent magnet made of neodymium iron boron (NdFeB) and nickel-plated. The magnet 30 is generally shaped to match the silicon steel sheets and is adhered to the iron core 32 using glue.

[0023] See also Figure 2 , Figure 2 Schematic diagram of the structure of an embodiment of the pasting assembly of the present application. The pasting assembly 10 is used to paste the magnetic steel (not shown) on the iron core 12. The pasting assembly 10 includes a positioning plate 100, a guide rail 102 and a movable part 104. Specifically, the positioning plate 100 is used to be set on one side of the iron core 12 to locate the pasting position and support the guide rail 102 and the movable part 104; the guide rail 102 can be fixed on the positioning plate 100 by screws or other fixing methods, and has a first extension direction (such as Figure 2 As shown by the double-headed arrows in FIG. 1 ). The movable member 104 is movably disposed on the guide rail 102 and can move along the first extension direction. Figure 3 , Figure 3 for Figure 2 Schematic diagram of the structure of an embodiment of the movable member. The movable member 104 has a support surface 1040 and a hollow area 1042 enclosed by the support surface 1040, so that a surface of the iron core 12 is exposed through the hollow area 1042, and the magnet is supported by the support surface 1040. When the movable member 104 moves to a first position along the first extension direction, the magnet is placed on the support surface 1040 of the movable member 104; when the movable member 104 moves to a second position along the first extension direction, the magnet is detached from the support surface 1040 to be attached to the surface of the iron core 12. In this embodiment, the first position and the second position can be set according to actual conditions. For example, the first position can be a position at one end of the guide rail 102 to which the movable member 104 can move along the guide rail 102 (a position close to the iron core 12), and the second position is a position at the other end of the guide rail 102 to which the movable member 104 can move along the guide rail 102 (a position away from the iron core 12).

[0024] The adhesive assembly 10 provided in the present application can ensure that when the movable part 104 moves along the guide rail 102, the magnet carried on the support surface 1040 of the movable part 104 slides off the surface of the movable part 104 under the action of gravity and the magnetic attraction between the movable part 104 and the iron core 12, and the angle between the magnet and the surface of the iron core 12 becomes smaller and smaller until the magnet and the surface of the iron core 12 are in contact. In addition, because the movable part 104 has a hollow area, it does not affect the glue or adhesive applied to the side of the magnet facing the iron core 12. The contact area between the movable part 104 and the surface of the iron core 12 is also small. Compared with the prior art method of directly pushing the magnet into the surface of the iron core 12 or press-bonding it to the surface of the iron core 12, the magnetic attraction that needs to be overcome is smaller, and the glue will not be squeezed out, thereby ensuring the accuracy and strength of the bond between the magnet and the iron core 12.

[0025] In one embodiment, Figure 2 and Figure 3 As shown, the movable member 104 includes a connecting portion 1044 and two oppositely disposed support portions 1046 of the same shape. The connecting portion 1044 connects one end of the two support portions 1046, giving the movable member 104 a U-shaped cross-section. The connecting portion 1044 and the support portions 1046 form a support surface 1040 on the side away from the positioning plate 100. The structural design of the movable member 104 is simple and easy to obtain. It can also reduce the contact area between the movable member 104 and the iron core 12 during movement, thereby reducing frictional resistance and greatly reducing the amount of glue / active agent removed from the surface of the iron core 12 by the movable member 104 during movement.

[0026] In addition, the two supporting portions 1046 and the connecting portion 1044 in the movable part 104 can be integrally formed, reducing the difficulty of process preparation. In addition, the spacing between the two supporting portions 1046 of the movable part 104 can be set according to actual conditions. For example, the outer peripheral surface of the iron core 12 may include a plurality of magnetic steel mounting grooves 120, and in the first extension direction perpendicular to the guide rail 102, the magnetic steel mounting grooves 120 have a first width, and the distance between the outermost edges of the two supporting portions 1046 can be equal to the width of the magnetic steel mounting grooves 120. This design method can make the magnetic steel carried on the movable part 104 fit better with the magnetic steel mounting grooves 120 of the iron core 12 at the corresponding position.

[0027] In one application scenario, the support portion 1046 of the movable member 104 in the above embodiment is wedge-shaped, with the connecting portion 1044 connected between the base B away from the tips A of the two support portions 1046. This wedge-shaped design allows the magnets carried on the support surface 1040 of the movable member 104 to slide off the movable member 104 more smoothly and gradually during movement, thereby more accurately adhering to the surface of the core 12 and preventing glue or adhesive from squeezing out of the adhesive surface. Of course, in other embodiments, the support portion 1046 of the movable member 104 may also be rectangular. When the height of the rectangle is relatively small, the magnets can also slide off the movable member 104 more easily.

[0028] In another application scenario, please refer to Figure 2 The adhesive assembly 10 provided in the present application further includes a handle 106, which is provided on the connecting portion 1044 of the movable member 104 and is used to drive the movable member 104 to move. In the present embodiment, the handle 106 can be a screw, and a threaded hole can be provided on the connecting portion 1044. One end of the screw can be fixedly connected to the threaded hole on the connecting portion 1044, and the other end of the screw is used to connect to an external power source. The power source can be a manual operator or a power device, and the present application does not limit this. Of course, in other embodiments, the structure of the handle 106 can also be other. The design of the handle 106 can make the movement of the movable member 104 smoother and more convenient during mechanical or manual operation.

[0029] In another embodiment, please refer to Figure 2 There are two guide rails 102, which are relatively spaced apart and arranged on the same side of the positioning plate 100. The movable member 104 is movably arranged between the two guide rails 102. The two supporting portions 1046 of the movable member 102 are movably connected to the adjacent guide rails 102 respectively; wherein, a first groove 1020 is provided on the side of the guide rail 102 facing the supporting portion 1046, and a first protrusion 1041 (such as Figure 3(as shown), the first protrusion 1041 is embedded in the first groove 1020. This design can better define the movement path of the movable member 104, reducing the probability of the movable member 104 deviating from the path during movement. Of course, in this embodiment, the number of the guide rail 102 can also be one, and it can be located on one side of one of the support portions 1046.

[0030] Further, in this embodiment, please continue to refer to Figure 2 In the first extension direction, the guide rail 102 has a first end 1022, and when the first protrusion 1041 and the first groove 1020 abut against each other at a position near the first end 1022 of the guide rail 102, the first end 1022 of the guide rail 102 is flush with the edge of the magnetic steel installation position on the surface of the iron core 12 away from the positioning plate 100, and the support portion 1046 is located on the side of the edge close to the positioning plate 100, and there is a gap between the edge. For example, the gap can be the same as the thickness of the magnetic steel. The first end 1022 of the guide rail 102 can be the end close to the iron core 12, and the position where the first protrusion 1041 and the first groove 1020 abut against each other can be called the first position. This design method can make the magnetic steel supported on the movable part 104 be aligned with the magnetic steel installation position on the surface of the iron core 12 before the movable part 104 moves away from the iron core 12, thereby making it easier for the magnetic steel to slide off the movable part 104 under the action of magnetic attraction.

[0031] In addition, if Figure 2 As shown, in the first extension direction, the guide rail 102 has a second end 1024 disposed opposite the first end 1022. The distance between the second end 1024 and the surface of the positioning plate 100 facing the iron core 12 is greater than or equal to the length of the support portion 1046 of the movable member 104. This design ensures that when the movable member 104 is completely away from the iron core 12 and the magnet is completely in contact with the surface of the iron core 12, the movable member 104 will not be separated from the guide rail 102. When the next magnet is attached, there is no need to reinstall the movable member 104 on the guide rail 102, thereby improving the efficiency of the magnet attachment process.

[0032] In another embodiment, please refer to Figure 2 and Figure 4 , Figure 4 for Figure 2 Schematic diagram of an exploded view of an embodiment of the positioning plate, positioning pins and iron core. The adhesive assembly 10 provided in the present application also includes a positioning pin 108 for fixing the position of the positioning plate 100 and the iron core 12. Preferably, as Figure 4As shown, in the first extension direction, the positioning plate 100 is provided with a first circular hole 1000 extending therethrough, and the surface of the iron core 12 facing the positioning plate 100 is provided with a second circular hole 122 corresponding to each magnetic steel mounting position 120. The positioning pin 108 is used to be inserted into the first circular hole 1000 and one of the second circular holes 122 on the iron core 12, so that the positioning plate 100 is fixedly arranged on one side of the iron core 12. Of course, in other embodiments, other types of positioning fixtures can also be used to relatively fix the positions of the positioning plate 100 and the iron core 12.

[0033] See also Figure 5-Figure 6 , Figure 5 This is a structural diagram of an embodiment of the magnetic steel pasting equipment of this application. Figure 6 for Figure 5 Schematic diagram of the structure of an embodiment of the rotating shaft and the iron core. The magnetic steel pasting device includes the pasting component 20, the rotating shaft 22 and the base 24 in any of the above embodiments; wherein the pasting component 20 is loosely sleeved on the outer periphery of the rotating shaft 22; the rotating shaft 22 is used to pass through the through hole (not shown) in the axial direction of the iron core 23, so that the iron core 23 is sleeved on the rotating shaft 22 to fix and rotate the iron core 23, for example, the outer wall of the rotating shaft 22 is fixedly connected to the inner wall of the through hole of the iron core 23; the base 24 includes a first abutting portion 240 and a second abutting portion 242 arranged opposite to each other, and the first abutting portion 240 and the second abutting portion 242 are respectively used to abut against the two ends of the rotating shaft 22 to fix the position of the rotating shaft 22. In this embodiment, the distance between the first abutting portion 240 and the second abutting portion 242 on the base 24 can be changed. On the one hand, the pasting component 20 in the above-mentioned magnet pasting device can make the magnet 25 carried on the supporting surface 2040 of the movable part 204 slide off the surface of the movable part 204 under the action of gravity and the magnetic attraction between the magnet 25 and the iron core 23 when the movable part 204 moves along the guide rail 200, and the angle between the magnet 25 and the surface of the iron core 23 becomes smaller and smaller until the magnet 25 is in contact with the surface of the iron core 23. And because the movable part 204 has a hollow area, it does not affect the glue or adhesive applied to the side of the magnet facing the iron core 12, and the contact area between the movable part 204 and the surface of the iron core 23 is also small. Compared with the prior art of directly pushing the magnet 25 into the surface of the iron core 23 or pressing it to the surface of the iron core 23, the magnetic attraction that needs to be overcome is smaller, and the glue will not be squeezed out, thereby ensuring the accuracy and strength of the bonding between the magnet 25 and the iron core 23; on the other hand, the above-mentioned rotating shaft 22 can drive the iron core 23 to rotate, so that the iron core 23 rotates from one of the magnet installation positions 230 to another magnet installation position 230, thereby improving the efficiency of pasting the magnet 25; on the other hand, the above-mentioned base 24 can better fix the position of the iron core 23, so that the position of the iron core 23 will not move during the pasting process of the magnet 25.

[0034] In one embodiment, Figure 5 As shown, the axial direction of the rotating shaft 22 is aligned with the first extension direction of the guide rail 200 (eg, Figure 5 In the axial direction of the rotating shaft 22, the positioning plate 202 is provided with a first through groove 1002 (as shown by the double-headed arrow in FIG); Figure 3 As shown in Figure 5 (not shown in the figure), the size of the first through-slot 1002 is larger than the outer diameter of the rotating shaft 22, so that the positioning plate 202 is loosely sleeved around the outer periphery of the rotating shaft 22. This design allows the rotating shaft 22 to rotate freely relative to the positioning plate 202, thereby making it easier for the rotating shaft 22 to subsequently drive the iron core 23 to rotate to the next magnet mounting slot 230 where no magnet 25 is attached.

[0035] In another embodiment, the rotating shaft 22 is a motor shaft, and the motor shaft and the iron core 23 form a rotor iron core. Of course, the rotating shaft 22 can also be other cylindrical components, which is not limited in this application. When the rotating shaft 22 is a motor shaft, the end of the rotating shaft 22 may be provided with a relatively important structure. In order to reduce the probability of it being damaged when it is hit by the base 24, please refer to Figure 5 and Figure 7 , Figure 7 for Figure 5The schematic structural diagram of an embodiment of the baffle and the cylinder, the magnetic steel pasting equipment provided by the present application also includes: a baffle 26 and a cylinder 28. The baffle 26 is passed through one end of the rotating shaft 22, and the baffle 26 and the positioning plate 202 are spaced relative to each other, and the spacing area between the baffle 26 and the positioning plate 202 is used to accommodate the iron core 23; the cylinder 28 is fixedly connected to the side of the baffle 26 away from the positioning plate 202, and is used to be sleeved on the periphery of one end of the rotating shaft 22, and the bottom of one end of the rotating shaft 22 abuts against the bottom of the cylinder 28. At this time, the second abutting portion 242 of the base 24 can directly abut against the cylinder 28. In addition, in this embodiment, the cylinder 28 and the baffle 26 can be integrally formed to reduce the complexity of the process preparation. In addition, the above-mentioned baffle 26 and the guide rail 200 jointly limit the movable range of the movable part 204, that is, the distance between two adjacent guide rails 200 is slightly larger than the width of the magnet 25, and the distance between the two supporting parts 2042 of the movable part 204 plus the width of the supporting part 2042 itself is equal to or slightly larger than the width of the magnet 25, so that the supporting part 2042 can support the magnet 25, so that the glue applied on the magnet 25 is not affected and the width is accurately matched with the magnet mounting position 230 on the iron core 23; the outer diameter of the baffle 26 is larger than the outer diameter of the iron core 23, so that when the movable part 204 reaches the first position, the baffle 26 presses against the guide rail 200, can clamp the magnet 25 on the supporting part 2042, prevent the magnet 25 from sliding out of the supporting part 2042, and make one edge of the magnet 25 coincide with an edge of the magnet mounting position 230 close to the baffle, so that the magnet 25 is accurately installed on the iron core 23. When the movable part 204 reaches the first position, the end of the support portion 2042 close to the baffle 26 can overlap with the edge of the magnet installation position 230 close to the baffle 26, or there can be a set distance from the edge of the magnet installation position 230 close to the baffle 26, so that the magnet 25 can more easily overlap with the edge when sliding off the support portion 2042, thereby improving the accuracy of the magnet installation.

[0036] Please refer again Figure 5 To further secure the position of the positioning plate 202, the magnetic steel attaching device further includes a clamp 21 located on the sides of the positioning plate 202 and the baffle 26 for clamping the positioning plate 202 and the baffle 26. The clamp 21 may be a door-shaped structure, for example, with one end fixedly connected to the baffle 26 and the other end detachably connected to the positioning plate 202.

[0037] In another embodiment, please refer to Figure 5 and Figure 8 , Figure 8 for Figure 5Schematic diagram of the structure of the movable part of the magnetic steel pasting device in the first position according to one embodiment. In the first extension direction, the first end 2000 of the guide rail 200 extends to be flush with the surface of the side of the baffle 26 facing the positioning plate 202. When the first groove 2002 provided on the guide rail 200 and the first protrusion (not shown) provided on the movable part 204 abut against each other near the first end 2000, the movable part 204 moves to the first position, and the first end 2000 protrudes from the support portion 2042 of the movable part 204, so that there is a gap between the support portion 2042 and the baffle 26. This design method can ensure that when the movable part 204 is in the first position, the magnet 25 on the movable part 204 can contact the surface of the iron core 23, thereby making it easier for the magnet 25 to slide off the movable part 204 under the action of magnetic attraction.

[0038] Please also refer to Figure 5 and Figure 9 , Figure 9 This is a flow chart of an embodiment of a magnetic steel pasting method of the present application, which includes:

[0039] S101: The rotating shaft 22 is passed through a through hole in the axial direction of the iron core 23 and fixedly connected to the iron core 23 , wherein a plurality of magnetic steel installation positions 230 are provided on the outer peripheral surface of the iron core 23 .

[0040] S102: The adhesive component 20 is gap-mounted on the periphery of the rotating shaft 22; wherein, the adhesive component 20 includes a positioning plate 202, a guide rail 200 and a movable part 204, the positioning plate 202 is fixedly arranged on one side of the iron core 23; the guide rail 200 is fixedly arranged on the positioning plate 202 and has a first extension direction; the movable part 204 is movably arranged on the guide rail 200 and can move along the first extension direction; the movable part 204 has a support surface 2040 and a hollow area (not marked) enclosed by the support surface 2040, and the movable part 204 corresponds to one of the magnetic steel installation positions 230.

[0042] Before or after the above step A, the pasting method provided in the present application may further include: fixing the guide rail 200 on the positioning plate 202 , where the guide rail 202 is located above the magnetic steel installation position 230 .

[0043] S103 : The two ends of the rotating shaft 22 are respectively pressed against the first abutting portion 240 and the second abutting portion 242 oppositely disposed on the base 24 .
