DETAILED DESCRIPTION

[0027] The embodiments of the utility model are described in detail below, the examples of the embodiments are shown in the drawings, wherein the same or similar reference signs represent the same or similar elements or elements with the same or similar functions throughout. The embodiments described below by referring to the drawings are exemplary, only for explaining the utility model, and cannot be understood as limiting the utility model.

[0028] The structure of the straight-line type stator assembly before winding is as shown in Figure 1 , comprising a plurality of stator monomers 1 arranged in straight lines and connected in sequence, as shown in Figure 5 , each stator monomer 1 comprises a stator core 101 and an injection molded framework 102 injection molded outside the stator core 101, as shown in Figure 4 , the stator core 101 comprises a stator yoke part 1011 and a stator tooth part 1012 located on the inner side surface of the stator yoke part 1011, after winding, the stator tooth parts 1012 of adjacent stator monomers 1 are tightened to form a columnar structure as shown in Figure 6 .

[0029] As shown in Figure 2 and Figure 3 , the clamp in the winding equipment comprises a clamping jaw 2 and a positioning plate 3, the clamping jaw 2 is clamped at one end of the stator monomer 1, and the positioning plate 3 extends outward with a plurality of T-shaped plates 301, the T-shaped plates 301 are used for contacting and positioning the other end of the stator monomer 1.

[0030] Example 1

[0031] like Figures 1-4 As shown, a stator assembly with positioning at both ends includes several stator units 1 connected sequentially on the sides. One axial end of the stator unit 1 is provided with a positioning groove 4 that cooperates with a positioning plate 3. A T-shaped plate 301 on the positioning plate 3 is locked in the positioning groove 4. The other axial end of the stator unit 1 has a positioning block 5 protruding along the axial direction, and a positioning block 5 is provided on each of the arc-shaped sides of the end of the stator unit 1. When the stator assembly is in a straight arrangement, two positioning blocks 5 on adjacent stator units 1 approach each other to form a positioning assembly 6 for clamping by the jaws 2 of the clamp in the winding equipment.

[0032] First, align the gripper 2 of the winding equipment (such as an automatic winding machine) with the positioning component 6, place the inline stator component into the fixture, and tightly fit the positioning slot 4 with the T-shaped plate 301 of the fixture. Finally, tighten and fix the gripper 2.

[0033] Positioning block 5 and positioning slot 4 serve to position and fix the inline stator assembly. When the inline stator assembly is placed in the fixture, they ensure accurate positioning of the inline stator assembly, reducing production time. In the subsequent winding process, they also play a fixing role, effectively preventing displacement of the inline stator assembly due to vibration and improving production efficiency.

[0034] This invention combines two adjacent stator units 1 with positioning blocks 5 to form a positioning component 6, which is held by the same gripper 2. This allows adjacent stator units 1 to be stably held simultaneously. The gripper 2 corresponds one-to-one with the positioning component 6, thereby fixing all stator units 1 together. This can prevent the inline stator assembly from shaking in the winding equipment and also prevent relative movement of the stator units 1 in the inline stator assembly.

[0035] Positioning blocks 5 are disposed on both sides of the arc at the end of stator unit 1. The arc at the end of stator unit 1 refers to the two sides of the end of stator unit 1 along the circumferential direction. Multiple stator units 1 can be arranged to form a cylindrical stator assembly, so the end face of stator unit 1 is arc-shaped. The positioning blocks 5 are disposed on both sides of the arc at the end of stator unit 1 by taking advantage of the characteristic that the in-line stator assembly is in an unfolded state when winding. At this time, the positioning blocks 5 on one side of two adjacent stator units 1 will move closer to each other.

[0036] The shape of the positioning slot 4 is designed according to the T-shaped plate 301; it only needs to be able to hold the T-shaped plate 301 in place. Figure 3 and Figure 4As shown, the positioning clamping groove 4 in the embodiment includes a limiting groove 401 and a limiting hole 402 located radially outside the limiting groove 401, the groove width a of the limiting groove 401 is greater than the hole diameter b of the limiting hole 402, the positioning plate 3 of the clamp passes through the limiting hole 402 and abuts against the surface of the limiting groove 401, specifically, the T-shaped plate 301 on the positioning plate 3 passes through the limiting hole 402, the inner bottom surface of the limiting groove 401 abuts against the end of the T-shaped plate 301, thereby achieving the radial limiting effect on the T-shaped plate 301, so as to realize the positioning of one end of the stator unit 1 by the positioning plate 3.

[0037] When the positioning clamping groove 4 is a closed ring structure, the T-shaped plate 301 needs to be a detachable structure, so that the T-shaped plate 301 can pass through the limiting hole 402 from the side where the limiting groove 401 is located and be connected with the main body of the positioning plate 3, but generally the positioning plate 3 is an integral structure, therefore, as shown in Figure 1 and Figure 3 , the positioning clamping groove 4 has an opening 403 extending from the center to one side, and the positioning plate 3 of the clamp enters the limiting hole 402 through the opening 403.

[0038] Since the clamp is located on the outer side of the in-line stator assembly, that is, on the outer side of the stator yoke 1011, the positioning clamping groove 4 and the positioning clamping block 5 are arranged along the outer edge of the stator yoke 1011 of the stator unit 1, so that the positioning clamping groove 4 and the positioning clamping block 5 are closer to the clamp. Here, the outer edge of the stator yoke 1011 is the outer edge of the injection molding framework 102 corresponding to the stator yoke 1011, and the positioning clamping groove 4 and the positioning clamping block 5 are fixed on the injection molding framework 102.

[0039] Embodiment Two

[0040] As shown in Figure 1 and Figure 6 , one end of the stator unit 1 is a terminal end 7, and the other end is a wire passing end 8, the winding passes through the wire from the end of the injection molding framework 102 away from the terminal (the wire passing end 8) and is connected with the terminal, the terminal is generally connected with the stator yoke 1011, and the winding wire passing is also located on the end face of the injection molding framework 102 where the stator yoke 1011 is located, so the terminal end 7 and the wire passing end 8 are both the end face of the stator unit 1 corresponding to the stator yoke 1011. The wire passing end 8 has an enameled wire passing through the wire, so it does not have a clamping space for the clamping jaw 2, therefore, in the embodiment, the positioning clamping block 5 is arranged at the terminal end 7, and the two positioning clamping blocks 5 are located on both sides of the terminal insertion port of the stator unit 1, and the positioning clamping groove 4 is arranged at the wire passing end 8. The positioning clamping groove 4 can be formed on the injection molding framework 102 at the end of the stator unit 1.

[0041] In order to ensure that the stator unit 1 is balanced in stress during the winding process, it is preferred that the positioning clamping groove 4 is located in the middle of the wire passing end 8 of the stator unit 1 in the circumferential direction.

[0042] Embodiment Three

[0043] On the basis of embodiment two, as shown in Figure 3 and Figure 4 The wire passing end 8 of the stator unit 1 is provided with a wire protection plate 9 extending along the outer edge, and the positioning clamping groove 4 is located on the wire protection plate 9.

[0044] After the winding of the stator assembly is completed, the stator assembly needs to be plastic encapsulated together with the terminal. The high-pressure injection material during injection molding will directly impact on the winding, and the enameled wire located at the wire passing end 8 is easy to be impacted out of the injection molding framework 102, resulting in breakage. Therefore, the wire protection plate 9 is arranged at the outer edge of the wire passing end 8 in the embodiment, and the positioning clamping groove 4 is integrally formed on the wire protection plate 9. The wire protection plate 9 realizes two functions, the first function is to avoid the winding from being impacted out of the injection molding framework 102 during the injection molding stage, and the second function is to cooperate with the T-shaped plate 301 to position during the winding stage, so as to simplify the structure of the stator assembly and improve the space utilization of the motor.

[0045] Generally, a wire separation plate 10 is further arranged on the radially inner side of the wire protection plate 9, and the wire protection plate 9 and the wire separation plate 10 form a wire protection groove 11. The wire protection groove 11 provides a line guiding function for the enameled wire. During the winding process, the enameled wire can clearly be wound from one winding groove to another winding groove along the path of the wire protection groove 11.

[0046] The positioning clamping groove 4 is preferably opposite to the wire separation plate 10, and at this time, the stator unit 1 can be a symmetrical structure, which is beneficial to balanced stress. In further design, the hole diameter b of the limiting hole 402 in the positioning clamping groove 4 is smaller than the circumferential length of the wire separation plate 10. The wire separation plate 10 is opposite to the wire protection plate 9, which can limit the two sides of the enameled wire, so as to avoid that one side of the enameled wire is pressed by the wire separation plate 10 and the other side is suspended, resulting in that the enameled wire is bent and deformed into the limiting hole 402.

[0047] In the description of the utility model, it is to be understood that the orientation or position relationship indicated by the terms "center", "inner", "outer", "axial", "radial", "circumferential" and the like is based on the orientation or position relationship shown in the drawings, and is only for the convenience of describing the utility model and simplifying the description, and therefore cannot be understood as a limitation on the utility model.

[0048] In the description of the utility model, the illustrative description of the terms does not necessarily refer to the same embodiment. Moreover, the specific features, structures, materials or characteristics described can be combined in any one or more embodiments in a suitable manner.

[0049] With the above ideal embodiment of the present application as the inspiration, through the above description, relevant staff can make various changes and modifications without deviating from the technical idea of the present application. The technical scope of the present application is not limited to the content in the specification, and the technical scope must be determined according to the scope of claims.
