Technical Field

[0002] Currently, during the motor assembly process, it is necessary to insert the first insulating paper 2' into the first wire slot 11' of the first stator core 1', and then install the first frame 3'. Figure 1 、 Figure 2 As shown, after the first insulating paper 2' is placed in the first wire slot 11', a first clip 31' is provided on the inner wall of the first skeleton 3' to fix the folded edge of the first insulating paper 2' in place, preventing the first insulating paper 2' from moving. However, some first stator cores 1' are relatively thick, and the first insulating paper 2' to be inserted is also relatively long, reaching a length of 10 cm or more. In this case, the first insulating paper 2' may rebound after being folded, 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 subsequently inserted, the folded edge of the first insulating paper 2' is located outside the first clip 31' of the first skeleton 3', and the first clip 31' cannot limit the first insulating paper 2' in place, affecting subsequent winding.

[0039] Reference Figure 3 、 Figure 7 and Figure 8The insulation paper correcting device provided by the embodiment of the present application is mainly used for correcting the rebounding insulation paper 70 in the wire slot 61 of the stator core 60, so that the insulation paper 70 is more fitted with the wire slot 61, and the lower framework 80 or the upper framework (not shown in the figure) can better fix the insulation paper 70 when the lower framework 80 or the upper framework is installed subsequently. Specifically, the insulation paper correcting device comprises a support 10 arranged above a conveying belt (not shown in the figure), a positioning disc 20 in a hollow structure arranged on the support 10, and a guide disc 30 arranged above the positioning disc 20 and movable up and down. A plurality of first guide blocks 21 are uniformly arranged on the inner side of the positioning disc 20, and the plurality of first guide blocks 21 correspond to the wire slots 61 on the stator core 60 one by one, so that when the stator core 60 moves upward, the plurality of first guide blocks 21 respectively slide into the wire slots 61. Referring to Figure 5 、 Figure 6 , the two side walls of each first guide block 21 are provided with a limiting groove 22 penetrating in the vertical direction. When the stator core 60 moves upward, the two edges of the insulation paper 70 are respectively clamped into the two limiting grooves 22, so that the two limiting grooves 22 fix the edges of the insulation paper 70. At the same time, the guide disc 30 arranged above protrudes a plurality of second guide blocks 31 downward, the plurality of second guide blocks 31 correspond to the plurality of wire slots 61 one by one, and can be respectively inserted into the plurality of wire slots 61 to press the insulation paper 70 to fit with the inner wall of the wire slot 61. In the present application, the plurality of first guide blocks 21 on the positioning disc 20 are used to position the folded edges of the insulation paper 70, and the plurality of second guide blocks 31 on the guide disc 30 are used to press the insulation paper 70, so as to correct the insulation paper 70, so that the insulation paper 70 can better fit with the wire slot 61, and facilitate the subsequent framework installation.

[0040] Referring to Figure 4 、 Figure 8 , the insulation paper 70 in the embodiment of the present application is also improved compared with the existing first insulation paper 2', to adapt to the foregoing correcting device. Specifically, in the present embodiment, the insulation paper 70 is folded from a rectangular insulation material paper, and after being folded along six longitudinal creases, the cross section is roughly matched with the shape of the wire slot 61. Specifically, the folded insulation paper 70 comprises a first folded edge 71 located in the middle, a second folded edge 72 located on each side of the first folded edge 71, a third folded edge 73 folded inward from the second folded edge 72, and a fourth folded edge 74 folded inward from the two third folded edges 73. The included angles between the first folded edge 71 and the second folded edge 72, the second folded edge 72 and the third folded edge 73, and 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 insulation paper 2', in the present embodiment, the fourth folded edge 74 is folded once more, that is, the fourth folded edge 74 is added, which is used to clamp into the limiting groove 22 to fix the insulation paper 70 and avoid rebounding.

[0041] Referring to Figure 5 、 Figure 6 In this embodiment, the positioning plate 20 includes a cylindrical body 23 with a hollow structure and a first flange 24 extending outward from the top of the cylindrical body 23. A plurality of first guide blocks 21 are arranged along the inner wall of the cylindrical body 23. The positioning plate 20 is fixed to the bracket 10 by the first flange 24. The two limiting grooves 22 on the first guide block 21 are arranged at an angle and are symmetrically arranged in an "eight" shape on the two side walls of the first guide block 21. The two fourth folded edges 74 are also folded inward, and their positions in the wire slot 61 correspond to the two limiting grooves 22 in the vertical direction. And because the two limiting grooves 22 are vertically continuous to the bottom of the first guide block 21, when the stator core 60 with the insulating paper 70 installed moves upward from the bottom of the positioning plate 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 move to the top of the two limiting grooves 22.

[0042] Depend on Figure 7 、 Figure 8 It can be seen 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 groove wall of the limiting groove 22 can also press the fourth folded edge 74 outward to make the third folded edge 73 fit better with the inner wall of the wire groove 61, so that when the lower frame 80 is inserted, the third folded edge 73 can be snapped into the buckle 81 of the lower frame 80.

[0043] Further, by Figure 6 As can be seen, each retaining groove 22 has a corner 221 on its opening. This corner 221 is located on the groove wall near the inner wall of the positioning plate 20. Corner 221 directly faces the fold between the third fold 73 and the fourth fold 74. This structure, with corner 221, provides clearance, allowing the fourth fold 74 to enter the retaining groove 22 more smoothly. Furthermore, once the fourth fold 74 has fully entered the retaining groove 22, corner 221 cooperates with the other wall of the retaining groove 22 to limit the insulating paper 70.

[0044] In this embodiment, the first guide block 21 has a rectangular cross-section, and the bottom of the first guide block 21 is tapered along the two long side walls of the rectangle. Because the retaining grooves 22 are located along the two long side walls, the bottom of the first guide block 21 is designed to be tapered. The bottom of the retaining grooves 22 is also tilted. This makes it easier for the top of the insulating paper 70 to fit into the tilted retaining grooves 22 when the stator core 60 moves upward.

[0045] Reference Figure 3In this embodiment, the bracket 10 includes a pillar 11 and a first support plate 12 and a second support plate 13 spaced apart from top to bottom on the pillar 11. The conveyor belt passes between the first support plate 12 and the second support plate 13. The positioning plate 20 is fixed to the first support plate 12 through a first flange 24. The insulating paper correction device also includes a lifting mechanism 40 provided under 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 to enter the hollow positioning plate 20, and causes the fourth folded edge 74 of the insulating paper 70 to be stuck in the limit groove 22 of the first guide block 21. Among them, the lifting mechanism 40 can be a lifting drive component such as a cylinder or an electric cylinder.

[0046] In this embodiment, the insulating paper correction device further includes a lifting mechanism 50 disposed above the conveyor belt, and the guide plate 30 is disposed on the lifting mechanism 50 and is driven to move up and down by the lifting mechanism 50. The lifting mechanism 50 can be a lifting drive component such as a pneumatic cylinder or an electric cylinder.

[0047] In this embodiment, refer to Figure 9 The guide plate 30 includes a second flange 32, and a plurality of second guide blocks 31 extending downward from the bottom of the second flange 32. Each second guide block 31 is longitudinally defined with a clearance groove 311 for clearing the first guide block 21. The clearance groove 311 extends upward through the second flange 32. When the guide plate 30 moves downward under the influence of the lifting mechanism 50, each second guide block 31 extends into each wire groove 61. At this time, the first guide block 21 clears the second guide block 31 through the clearance groove 311.

[0048] In this embodiment, the cross-section of the second guide block 31 matches that of the insulating paper 70. When the second guide block 31 is inserted into the wire slot 61, the outer wall of the second guide block 31 fits against the folded edges of the insulating paper 70. This outer wall of the second guide block 31 presses against the folded edges of the insulating paper 70, further converging it against the inner wall of the wire slot 61. Similarly, to facilitate insertion of the second guide block 31 into the wire slot 61, the bottom of the second guide block 31 is tapered along the two long sides of the rectangle.

[0049] The embodiment of the present application also provides a motor assembly device (not shown in the figure) for assembling the stator core 60, including a work platform, a conveyor belt arranged on the work platform, an insulating paper insertion device arranged on the conveyor belt, a lower frame installation device, an iron core turning device, an upper frame installation device, and also includes the insulating paper correction device provided in any of the above embodiments. In the motor assembly device, the stator core 60 is transported on the conveyor belt, and the insulating paper 70 is first inserted into the insulating paper insertion device, and then transported to the insulating paper correction position for correction of the insulating paper 70. After the correction is completed, the lower frame installation device installs the lower frame 80, and then the iron core is inverted by the iron core turning device, and finally the installation of the upper frame is completed. In the embodiment of the present application, an insulating paper correction device is provided in the motor assembly equipment to solve the rebound problem of the longer insulating paper 70, improve production efficiency, and ensure assembly quality.

[0050] The above is only a specific implementation method of the present application, but the scope of protection of the present application is not limited thereto. Any technician familiar with this technical field can easily think of changes or replacements within the technical scope disclosed in this application, which should be covered by the scope of protection of the present application.
