The embodiments described below with reference to the accompanying drawings are exemplary and are intended only to explain the present invention and are not to be construed as limiting the present invention.

Therefore, the features defined as "first" and "second" may explicitly or implicitly include one or more of the features. In the description of the present invention, "multiple" means two or more, unless otherwise clearly and specifically defined.

[0037] In the description of this utility model, it should be noted that, unless otherwise expressly specified or limited, the terms "installed," "connected," and "connected" should be understood in a broad sense. For example, they can refer to fixed connections, detachable connections, or integral connections; mechanical connections or electrical connections; direct connections or indirect connections through an intermediate medium; and can refer to internal communication between two components or the interaction between two components. Those skilled in the art will understand the specific meanings of the above terms in this utility model based on specific circumstances.

[0038] When the magnet is pressed into the magnet slot of the motor rotor in the related art, it is often necessary to drive the magnet to a predetermined position through a driving structure, and then be pressed into the magnet slot by the pressing structure, which makes the magnet pressing structure more complicated. In addition, the magnet pressing structure in the related art also needs to determine the polarity of the magnet, which increases the complexity of the work.

[0039] The present application proposes a magnetic steel press-fitting device 100 , which can simplify the structure of the magnetic steel press-fitting device 100 and automatically determine the polarity of the magnetic steel 20 , thereby reducing work difficulty and improving work efficiency.

[0040] Reference below Figures 1-6 A magnetic steel press-fitting device 100 according to an embodiment of the present invention is described.

[0041] like Figures 1-6 As shown, the magnetic steel pressing device 100 according to the embodiment of the present invention can be used for the motor rotor 10. The magnetic steel pressing device 100 includes a base 1, a material rack 2 and a first driving component 4. The motor rotor 10 is installed on the base 1. The material rack 2 includes a material plate 21 and a material trough 22. The material plate 21 is located above the base 1. The material trough 22 is installed on the material plate 21. The end of the material trough 22 has a discharge port. A magnetic member 3 is provided at the discharge port. The magnetic member 3 is magnetically attracted to the magnetic steel 20 in the material trough 22. A magnetic steel through-hole 211 is provided at the end of the material trough 22 adjacent to the magnetic member 3. The magnetic steel through-hole 211 passes through the material plate 21 in the up and down directions and is opposite to the magnetic steel slot of the motor rotor 10 in the up and down directions. The first driving component 4 includes a driving member 41 and a pressing tongue 42. The driving member 41 is suitable for driving the pressing tongue 42 so that the magnetic steel 20 is pressed into the magnetic steel slot through the magnetic steel through-hole 211.

[0042] That is to say, when the magnets 20 are placed in the material slot 22 in a stacked manner, since the magnets 20 are used for the motor rotor 10, the magnets 20 are either N-pole magnets or S-pole magnets. Therefore, taking the magnets 20 as S-pole magnets as an example, an N-pole magnetic part 3 is set at the end of the material slot 22, and the S-pole magnets can be better placed in the material slot 22. Moreover, when the magnets 20 opposite to the magnet through-hole 211 are pressed downward by the pressing tongue 42 into the magnet slot of the motor rotor 10, the remaining S-pole magnets can still be better accommodated in the material slot 22 in a stacked manner and be adsorbed on the magnetic part 3 with the N pole, so that the magnet pressing device 100 does not need to be provided with a driving structure for pushing the magnets 20 to move in the material slot 22, which can simplify the magnet pressing device 100, and also because the driving structure for pushing the magnets 20 to move in the material slot 22 is saved, the cost of the magnet pressing device 100 can be reduced.

[0043] In addition, it should be noted that since the magnetic part 3 is a N-pole magnetic part 3, when the N-pole magnet is placed in the material slot 22, the N-pole magnet will be spread out by the N-pole magnetic part 3 due to the repulsion of like charges. Therefore, the magnet pressing device 100 of the present application also has a certain error prevention capability, so that in the process of placing the magnet 20 in the material slot 22, it can be easily determined whether the wrong magnet is placed in the material slot 22, which can simplify the work difficulty and improve work efficiency.

[0044] In the above examples, only the magnet 20 is taken as an S-pole magnet, but this is not a limitation of the present application. The magnet can also be an N-pole magnet, and the corresponding solution will not be repeated.

[0045] Therefore, according to the magnetic steel pressing device 100 of the embodiment of the present invention, by providing the magnetic member 3 at the end of the material slot 22, the magnetic steel pressing device 100 does not need to be provided with a driving structure for pushing the magnetic steel 20 to move within the material slot 22, which can simplify the magnetic steel pressing device 100. Moreover, since the driving structure for pushing the magnetic steel 20 to move within the material slot 22 is omitted, the cost of the magnetic steel pressing device 100 can be reduced. In addition, the magnetic steel pressing device 100 of the present application also has a certain error-proofing capability, so that when the magnetic steel 20 is placed in the material slot 22, it can be easily determined whether the wrong magnetic steel 20 has been placed in the material slot 22, which can simplify the work difficulty and improve work efficiency.

[0046] In some embodiments of the present invention, the magnetic steel slots include multiple N-pole magnetic steel slots 101 and multiple S-pole magnetic steel slots 102, and multiple material slots 22 are provided. Each material slot 22 is provided with a magnetic steel through-hole 211, and the multiple magnetic steel through-holes 211 correspond one-to-one to the multiple N-pole magnetic steel slots 101, and / or, the multiple magnetic steel through-holes 211 correspond one-to-one to the multiple S-pole magnetic steel slots 102, wherein the pressing tongues 42 are provided in plurality, and the multiple magnetic steel through-holes 211 correspond one-to-one to the multiple pressing tongues 42.

[0047] like Figures 1-6 In the example shown, the magnetic steel slots include four N-pole magnetic steel slots 101 and four S-pole magnetic steel slots 102, four material slots 22 are provided, and four magnetic steel through holes 211 are provided. The end of the N-pole material slot 22 is placed with the S-pole magnetic part 3, and the end of the S-pole material slot 22 is placed with the N-pole magnetic part 3. As a result, the N-pole magnetic steel can be better placed in the N-pole material slot 22, and the S-pole magnetic steel can be better placed in the S-pole material slot 22. When the first driving component 4 is working, the driving member 41 can drive the pressing tongue 42 to apply downward pressing force to the N-pole magnetic steel and the S-pole magnetic steel, so that the N-pole magnetic steel is pressed into the N-pole magnetic steel slot 101, and the S-pole magnetic steel is pressed into the S-pole magnetic steel slot 102. The operation is simple and convenient, and can improve work efficiency.

[0048] In some embodiments of the present invention, Figures 1-6 As shown, a first positioning portion is provided on the base 1, and a second positioning portion is provided on the motor rotor 10. There are multiple second positioning portions, and the multiple second positioning portions correspond one-to-one to the multiple N-pole magnetic steel slots 101, and / or the multiple second positioning portions correspond one-to-one to the multiple S-pole magnetic steel slots 102. Therefore, through the cooperation of the first positioning portion and the second positioning portion, the motor rotor 10 can be better positioned, so that the magnetic steel slots of the motor rotor 10 are opposite to the magnetic steel through-holes 211, and the second positioning portions are arranged opposite to the N-pole magnetic steel slots 101 or the S-pole magnetic steel slots 102, which can reduce the difficulty of calibration, thereby reducing the difficulty of processing the second positioning portions.

[0049] In some embodiments of the present invention, Figures 1-6 As shown, the base 1 includes a base body 11 and a column 12. The rotor is sleeved on the column 12 and supported on the base body 11. The column 12 is provided with a first positioning portion. Thus, through the cooperation between the first positioning portion on the main body and the second positioning portion on the inner wall of the rotor, the rotor can be well positioned in the circumferential direction, and the magnetic steel slots of the motor rotor 10 can be well aligned with the magnetic steel through-holes 211, thereby facilitating the press-fitting of the magnetic steel.

[0050] Alternatively, as Figures 1-6 As shown, the first positioning portion is a positioning protrusion 121, and the second positioning portion is a positioning groove 103. The positioning protrusion 121 and the positioning groove 103 have a simple structure and good positioning effect, which not only reduces processing cost and difficulty, but also facilitates the mutual positioning between the base 11 and the motor rotor 10.

[0051] In some embodiments of the present invention, Figures 1-6As shown, the material rack 2 further includes a guide member 5, which is mounted on the material plate 21. The guide member 5 has a guide hole 521 that guides and cooperates with the pressing tongue 42, and the magnetic member 3 is mounted on the guide member 5. In other words, when assembling the magnetic member 3, the magnetic member 3 can be pre-installed on the guide member 5 before the guide member 5 is installed on the material plate 21. This reduces the difficulty of assembling the magnetic member 3. In addition, the guide member 5 can also better guide the pressing tongue 42, allowing the pressing tongue 42 to more reliably press the magnetic steel 20 downward, thereby improving stability.

[0052] In the embodiment of the present utility model, as Figures 1-6 As shown, the guide member 5 includes: a fixed block 51 and a guide block 52. The fixed block 51 is mounted on the material plate 21 and includes a first portion and a second portion in the vertical direction. The guide block 52 is connected to the outer periphery of the first portion to construct a receiving space between the second portion and the guide block 52. The magnetic member 3 is mounted in the receiving space, and the guide hole 521 is located on the guide block 52. In other words, the guide member 5 is "T"-shaped in cross section. Through the structural design of the guide member 5, not only can the guide member 5 better guide the pressing tongue 42, but also the magnetic member 3 can be hidden in the receiving space of the guide member 5, so that the material trough 22 facing the magnetic member 3 can better construct a magnetic steel through hole 211 opposite to the pressing tongue 42 in the vertical direction. The size of the magnetic steel through hole 211 is just enough to accommodate a piece of magnetic steel 20 and also just enough to allow the pressing tongue 42 to pass through. When the pressing tongue 42 presses down a piece of magnetic steel 20, it is not easy to interfere with the other magnetic steels 20.

[0053] In some embodiments of the present invention, Figures 1-6 As shown, the material rack 2 also includes a mounting block 6, which is installed in the accommodating space. At least one magnetic component 3 is installed on the mounting block 6. When there are multiple magnetic components 3, multiple material troughs 22 are provided, and the multiple magnetic components 3 correspond one-to-one to the multiple material troughs 22.

[0054] like Figures 1-6 As shown, two mounting blocks 6 are provided, and two magnetic parts 3 can be installed on each mounting block 6 respectively. The two magnetic parts 3 are respectively located at the ends of the two material troughs 22. Therefore, when assembling the magnetic parts 3, the magnetic parts 3 can be pre-installed on the mounting blocks 6, and then the mounting blocks 6 are installed in the accommodating space, which can effectively reduce the difficulty of assembling the magnetic parts 3.

[0055] In some embodiments of the present invention, Figures 1-6As shown, the material rack 2 also includes a guide assembly 7, which includes: at least one guide column 71, a mounting plate 72 and a movable plate 73. The guide column 71 extends in the up and down directions, and the lower end of the guide column 71 is connected to the material plate 21; the mounting plate 72 is installed at the upper end of the guide column 71, the driving member 41 is installed on the mounting plate 72, the movable plate 73 is transmission-connected to the driving member 41, the movable plate 73 has a guide hole 521 that cooperates with the guide column 71, and the pressing tongue 42 is connected to the lower end of the movable plate 73.

[0056] like Figures 1-6 As shown, two guide pillars 71 are provided, and the mounting plate 72 is installed above the two guide pillars 71. The movable plate 73 is provided with two guide holes 521, and the two guide holes 521 respectively cooperate with the two guide pillars 71. By providing the movable plate 73, the pressing tongue 42 can be better provided at the lower end of the movable plate 73. The number of the pressing tongues 42 can be relatively easily provided, which can reduce the difficulty of production. Moreover, through the guidance of the two guide pillars 71, the movable plate 73 can move up and down more stably, so that the pressing tongue 42 can stably apply downward pressure to the magnet 20, and finally the magnet 20 can be better pressed into the magnet groove, with high reliability and good stability.

[0057] In some embodiments of the present invention, Figures 1-6 As shown, the magnetic steel pressing device 100 further includes a second driving assembly 8, which is used to drive the base 1 to move in the up and down directions so that the motor rotor 10 installed on the base 1 abuts against the material plate 21 in the up and down directions.

[0058] That is to say, when the first drive component 4 drives the magnet 20 to move downward, in order to enable the magnet 20 to better enter the magnet groove, the second drive component 8 can be set to drive the base 1 upward, so that the motor rotor 10 and the material plate 21 are abutted up and down, so that the magnet groove of the motor rotor 10 is opposite to the magnet through hole 211, thereby, the magnet 20 can be better pressed into the magnet groove.

[0059] Other structures and operations of the magnetic steel press-fitting device 100 according to the embodiment of the present invention are known to those skilled in the art and will not be described in detail here.
