Description

Technical Field

[0002] Currently, during the motor assembly process, a first insulating paper 2' needs to be inserted into the first wire slot 11' of the first stator core 1', and then a first skeleton 3' is installed. Referring to Figure 1 、 Figure 2 As shown, after the first insulating paper 2' is placed in the first wire slot 11', a first buckle 31' is provided on the inner wall of the first skeleton 3' to fix and limit the folded edge of the first insulating paper 2', so that the first insulating paper 2' cannot move. However, some first stator cores 1' are relatively thick, and the first insulating paper 2' to be inserted is also relatively long, with a length that can reach 10 cm or more. In this way, the first insulating paper 2' rebounds after folding, resulting in the first insulating paper 2' not being able to fit the inner wall of the first wire slot 11'. When the first skeleton 3' is inserted subsequently, the folded edge of the first insulating paper 2' is located outside the first buckle 31' of the first skeleton 3', and the first buckle 31' cannot limit the first insulating paper 2', affecting the subsequent wire winding.

[0021] Referring to Figure 3 、 Figure 7 and Figure 8 and , an insulating paper correction device provided by an embodiment of the present application is mainly used to correct the insulating paper 70 that rebounds in the slot 61 of the stator core 60, so that the insulating paper 70 fits better with the slot 61, so that when the lower skeleton 80 or the upper skeleton (not shown in the figure) is installed subsequently, the lower skeleton 80 or the upper skeleton can better fix the insulating paper 70. Specifically, the insulating paper correction device includes a bracket 10 disposed above a conveyor belt (not shown in the figure), a positioning disk 20 disposed on the bracket 10 and having a hollow structure, and a guiding disk 30 disposed above the positioning disk 20 and capable of moving up and down. A plurality of first guiding blocks 21 are uniformly disposed inside the positioning disk 20, and the plurality of first guiding blocks 21 correspond to the slots 61 on the stator core 60 one by one, so that when the stator core 60 moves upward, the plurality of first guiding blocks 21 respectively slide into the slots 61. Referring to Figure 5 、 Figure 6, on both side walls of each first guiding block 21, limiting grooves 22 are penetrated and arranged along the vertical direction. When the stator core 60 moves upward, the two edges of the insulating paper 70 are respectively just clamped into the two limiting grooves 22. In this way, the two limiting grooves 22 fix the edges of the insulating paper 70. At the same time, a plurality of second guiding blocks 31 protrude downward from the upper guiding disk 30. The plurality of second guiding blocks 31 correspond to the plurality of wire grooves 61 one by one and can be respectively inserted into the plurality of wire grooves 61 to press the insulating paper 70 to make it fit with the inner wall of the wire groove 61. In this application, the folded edges of the insulating paper 70 are positioned by the plurality of first guiding blocks 21 on the positioning disk 20. At the same time, the insulating paper 70 is pressed by the plurality of second guiding blocks 31 on the guiding disk 30 to correct the insulating paper 70, so that the insulating paper 70 can better fit with the wire groove 61, facilitating the subsequent installation of the skeleton.

[0022] Refer to Figure 4 , Figure 8 , in the embodiment of this application, the insulating paper 70 is also improved compared with the existing first insulating paper 2' to adapt to the aforementioned correcting device. Specifically, in this embodiment, the insulating paper 70 is bent from a rectangular insulating material paper. After being bent along six longitudinal creases, its cross-section roughly matches the shape of the wire groove 61. Specifically, the folded insulating paper 70 includes a first folded edge 71 in the middle, second folded edges 72 respectively located on both sides of the first folded edge 71, third folded edges 73 respectively folded inward from the second folded edges 72, and fourth folded edges 74 respectively folded inward from the two third folded edges 73. The included angles between the first folded edge 71 and the second folded edge 72, between the second folded edge 72 and the third folded edge 73, and between the third folded edge 73 and the fourth folded edge 74 are all obtuse angles. Among them, the fourth folded edge 74 is the narrowest. Compared with the existing first insulating paper 2', in this embodiment, it is folded one more time, that is, the fourth folded edge 74 is added. The insulating paper 70 is fixed by using the fourth folded edge 74 to be clamped into the limiting groove 22 to avoid rebound.

[0023] Refer to Figure 5 , Figure 6, in this embodiment, the positioning disk 20 includes a columnar body 23 with a hollow structure and a first flange 24 extending outward from the top of the columnar body 23. A plurality of first guide blocks 21 are arranged along the inner wall of the columnar body 23. The positioning disk 20 is fixed to the bracket 10 through the first flange 24. The two limiting grooves 22 on the first guide block 21 are inclined and symmetrically arranged on the two side walls of the first guide block 21 in an eight-character shape. The two fourth folded edges 74 are also folded inward, and their positions in the wire groove 61 correspond to the two limiting grooves 22 in the vertical direction. And since the two limiting grooves 22 penetrate to the bottom of the first guide block 21 in the vertical direction, in this way, when the stator core 60 with the insulating paper 70 is moved upward from the bottom of the positioning disk 20, the tops of the two fourth folded edges 74 of the insulating paper 70 slowly move upward from the bottom of the two limiting grooves 22 until they reach the tops of the two limiting grooves 22.

[0024] It can be seen from Figure 7 , Figure 8 that, since the fourth folded edge 74 is folded inward along the third folded edge 73, when the fourth folded edge 74 is limited in the limiting groove 22, the pressing action of the groove wall of the limiting groove 22 on the fourth folded edge 74 outward can also make the third folded edge 73 fit more closely to the inner wall of the wire groove 61, so that when the lower skeleton 80 is inserted, the third folded edge 73 can be stuck into the buckle 81 of the lower skeleton 80.

[0025] Furthermore, it can be seen from Figure 6 that on the groove wall of the opening of each limiting groove 22, there is a corner 221, and the corner 221 is arranged on the groove wall close to the inner wall of the positioning disk 20. The corner 221 is opposite to the crease between the third folded edge 73 and the fourth folded edge 74. With this structure, by setting the corner 221, on the one hand, it provides a clearance space to make the fourth folded edge 74 enter the limiting groove 22 more smoothly; on the other hand, when the fourth folded edge 74 completely enters the limiting groove 22, the corner 221 cooperates with the other groove wall of the limiting groove 22 to limit the insulating paper 70.

[0026] In this embodiment, the cross-section of the first guide block 21 is rectangular, and the bottom of the first guide block 21 is relatively inclined along the two long side walls of the rectangle to form a cone shape. Since the limiting grooves 22 are arranged along the side walls where the two long sides are located, in this way, by designing the bottom of the first guide block 21 to be an inclined cone shape, the bottom of the limiting groove 22 is also inclined. In this way, when the stator core 60 moves upward, the top of the insulating paper 70 is more likely to be inserted into the inclined limiting groove 22.

[0027] Referring to Figure 3, in this embodiment, the bracket 10 includes a column 11, and a first support plate 12 and a second support plate 13 that are spaced from top to bottom on the column 11. The conveyor belt passes between the first support plate 12 and the second support plate 13. The positioning disk 20 is fixed to the first support plate 12 through a first flange 24. The insulating paper correction device further includes a lifting mechanism 40 disposed below the conveyor belt, and the lifting mechanism 40 is fixed to the second support plate 13. The lifting mechanism 40 drives the stator core 60 on the conveyor belt to move upward into the hollow positioning disk 20, and makes the fourth folded edge 74 of the insulating paper 70 snap into the limiting groove 22 of the first guiding block 21. Among them, the lifting mechanism 40 can be a lifting drive member such as a cylinder or an electric cylinder.

[0028] In this embodiment, the insulating paper correction device further includes a lifting mechanism 50 disposed above the conveyor belt, and the guiding disk 30 is disposed on the lifting mechanism 50 and is driven to move up and down by the lifting mechanism 50. Among them, the lifting mechanism 50 can be a lifting drive member such as a cylinder or an electric cylinder.

[0029] In this embodiment, refer to Figure 9 , the guiding disk 30 includes a second flange 32, and a plurality of second guiding blocks 31 extend downward along the bottom of the second flange 32. Each second guiding block 31 is provided with an avoidance groove 311 for avoiding the first guiding block 21 along the longitudinal direction, and the avoidance groove 311 penetrates the second flange 32 upward. When the guiding disk 30 moves downward driven by the lifting mechanism 50, each second guiding block 31 respectively extends into each wire groove 61, and at this time, the first guiding block 21 avoids the second guiding block 31 through each avoidance groove 311.

[0030] In this embodiment, the cross-section of the second guiding block 31 matches the cross-section of the insulating paper 70. When the second guiding block 31 is inserted into the wire groove 61, the outer walls of the second guiding block 31 are respectively attached to the folded edges of the insulating paper 70, and the outer walls of the second guiding block 31 press against the folded edges of the insulating paper 70 to make them fit more closely with the inner wall of the wire groove 61. Similarly, in order to facilitate the insertion of the second guiding block 31 into the wire groove 61, the bottom of the second guiding block 31 is relatively inclined along the two long side walls of the rectangle to form a cone shape.

[0031] The embodiment of the present application further provides a motor assembly device (not shown in the figure) for assembling the stator core 60, which includes a working platform, a conveyor belt provided on the working platform, an insulating paper inserting device provided on the conveyor belt, a lower skeleton mounting device, a core flipping device, an upper skeleton mounting device, and further includes the insulating paper correcting device provided in any of the above embodiments. In the motor assembly device, the stator core 60 is transported on the conveyor belt. First, the insulating paper 70 is inserted by the insulating paper inserting device, and then it is transported to the insulating paper correcting position for correcting the insulating paper 70. After the correction is completed, the lower skeleton mounting device mounts the lower skeleton 80, and then the core is inverted by the core flipping device, and finally the upper skeleton is mounted. In the embodiment of the present application, the insulating paper correcting device is provided in the motor assembly device, which solves the problem of the rebound of the long insulating paper 70, improves the production efficiency, and ensures the assembly quality.

[0032] The above is only the specific implementation manner of the present application, but the protection scope of the present application is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present application can easily think of changes or substitutions, which should all be covered within the protection scope of the present application.
