[0018] Example:

[0019] like Figure 1-4As shown, a stator winding machine includes a frame 1 for supporting weight and housing other components. The frame 1 is equipped with a loading / unloading assembly 2, a wire feeding assembly 7, a gripping assembly (not shown), a positioning assembly 3, a winding assembly 4, a wire clamping assembly 5, and a wire cutting assembly 6. The loading / unloading assembly provides the stator 9 to be wound. The gripping assembly is a robotic arm structure used to move the stator 9 to be wound onto the positioning assembly 3 and to return the wound stator to the loading / unloading assembly 2. The positioning assembly 3 includes a fixed plate 31 and a rotating plate 3. 2 and positioning plate 33, the fixed plate 31 is mounted on the frame 1 and can move relative to the frame 1, the rotating plate 32 is mounted on the fixed plate 31 and can rotate relative to the fixed plate 31, the positioning plate 33 is fixed on the rotating plate 32, the positioning plate 33 is provided with clamping member 331, the clamping member 331 matches the stator edge 91, the positioning assembly 3 is used to fix the stator 9 to be wound, and rotates during the winding process to realize winding of different wire slots on the stator 9 to be wound; the wire cutting assembly 6 and the wire clamping assembly 5 are located near the winding assembly 4 The winding assembly 4 is movable relative to the frame 1. The wire cutting assembly 6 is used to cut the wire on the stator after winding. The wire clamping assembly 5 is used to position the copper wire at the beginning of winding and to clamp the copper wire before cutting after winding, so as to facilitate the positioning of the copper wire when winding the next stator 9. The winding assembly 4 includes a rotating part 41, a first rotating coil 42, a second rotating coil 43, and a limiting plate 44. The limiting plate 44 restricts the first rotating coil 42 and the second rotating coil 43 on the rotating part 41. The rotating part 41 controls the first rotating coil 42 and the second rotating coil 43. The wire reel 43 rotates, and the first wire reel 42 and the second wire reel 43 are located in a rotation interval 421. The first wire reel 42 and the second wire reel 43 are provided with wire openings 431. The wire feeding assembly 7 includes a wire assembly 71 and a wire rod 72, which are used for positioning and transmitting the wound copper wire. The copper wire passes through the wire assembly 71 of the wire feeding assembly 7, passes through the wire rod 72 and enters the rotation interval 421 between the first wire reel 42 and the second wire reel 43. It then passes out from the wire opening 431 and is clamped and fixed by the wire clamping assembly 5.After the gripping component grips the stator 9 to be wound, it moves it to the clamping member 331. The clamping member 331 clamps the edge 91 of the stator to be wound, thus fixing the stator 9. The fixing plate 31 moves to the vicinity of the winding component 4. During the rotation of the rotating plate 32, the positioning plate 33 is driven to rotate, allowing the stator 9 to be wound to enter the winding opening 431. The wire groove on the stator 9 to be wound corresponds to the rotation range 421 between the first winding disc 42 and the second winding disc 43. When the first winding disc 42 and the second winding disc 43 rotate, the copper wire begins to be wound in the wire groove. After the winding begins, the clamping component 5 is released, and the first winding disc 42 and the second winding disc 43 rotate at high speed to wind the wire. The rotation of the rotating plate 32 drives the stator 9 to be wound. The stator 9 rotates to wind wires into different slots. After winding, the stator rotates out from the winding opening 431, and the copper wire is also pulled out from the winding opening 431. The wire clamping assembly 5 moves and clamps the copper wire, and the wire cutting assembly 6 moves and cuts the copper wire between the wire clamping assembly 5 and the stator. After the fixing plate 31 moves, the gripping assembly grips the stator and moves it to the loading and unloading assembly 2, completing the automated winding of the semi-circular stator. The structures of the gripping assembly, wire clamping assembly 5, wire cutting assembly 6, positioning assembly 3, rotating plate 32, and positioning plate 33, which enable movement, rotation, and fixing in the above implementation process, are conventional techniques used by those skilled in the art in the field of winding machines, and this utility model will not describe them in detail.

[0020] Based on the above embodiments, in order to improve efficiency, the gripping component, positioning component 3, winding component 4, wire clamping component 5, and wire cutting component 6 are in two sets. Through a dual-axis design, two sets of stators 9 to be wound are wound simultaneously, improving production efficiency. During dual-axis production, because two sets are processed simultaneously, the stators and stator fixing mold 8 occupy a large space. To further improve production efficiency, a connection method is provided for the loading / unloading component 2. Specifically, the loading / unloading component 2 includes the first transmission device 21 and the second transmission device 22. The frame 1 is also equipped with a mold feeding gripping component (not shown in the figure). The stator is placed on the stator fixing mold 8. The stator fixing mold 8 is picked up by the mold feeding and gripping assembly on the second transmission device 22 and moved to the first transmission device 21. Then, the gripping assembly picks up the winding stator 9 and moves it to the clamping member 331. After the winding is completed, the stator is moved back to the stator fixing mold 8 by the gripping assembly. In order to reduce the error of each action and improve the production efficiency, the first transmission device 21 and the second transmission device 22 move in the same direction. The first transmission device 21 is equipped with a first sensing component 211 and the second transmission device 22 is equipped with a second sensing component 221. The sensing settings can more accurately control the gripping accuracy of the gripping assembly and the mold feeding and gripping assembly.

[0021] The beneficial effects of this utility model are: it proposes a stator winding machine that achieves automated winding of semi-circular multi-groove wires through the cooperation of components such as gripping component, positioning component 3, winding component 4, wire clamping component 5, and wire cutting component 6.

[0022] In summary, the technical solutions in the above embodiments can be combined with each other, and other combinations not described in this specification should also be within the protection scope of this utility model.
