[0045] The following is combined with Figure 1-Figure 9 This application is described in further detail.

[0046] The embodiment of the present application discloses a stator winding machine.

[0047] A stator winding machine comprises a workbench 1, a pick-up and delivery mechanism 2, a winding fixture 3, a wire arrangement mechanism 4, a winding mechanism 5 and a wire breaking mechanism 6.

[0048] First, the stator 7 is placed on the pick-up and delivery mechanism 2, and the stator 7 to be wound is placed on the winding fixture 3 by the pick-up and delivery mechanism 2. Before the stator 7 is wound, a smooth wire entry channel is formed at the slot of the stator 7 by the wire arrangement mechanism 4. Then, the wire is thrown from the wire entry channel into the slot of the stator 7 by the winding mechanism 5, and the wire is wound on the stator 7.

[0049] When the stator 7 needs to be rotated, the stator 7 can be driven to rotate by the winding fixture 3. When the wire needs to be cut, the wire is cut by the wire cutting mechanism 6, and the cut wire is collected. After the stator 7 is wound, the stator 7 that has been wound is taken down again by the pick-up and delivery mechanism 2, and the stator 7 to be wound is placed on the winding fixture 3.

[0050] The winding fixture 3 includes a placement member 31 and a pressing member 32. The pressing member 32 is located above the placement member 31. After the stator 7 is placed on the placement member 31, the pressing member 32 presses the stator 7 against the placement member 31 to improve the placement stability of the stator 7. The placement member 31 includes a rotating rod 311 and a placement seat 312.

[0051] The rotating rod 311 is vertically mounted on the workbench 1 and rotates with the workbench 1 around its own axis. A motor is provided at the bottom of the rotating rod 311, and the rotating rod 311 is driven to rotate by the motor and the transmission rod. A positioning pin is provided at the top of the rotating rod 311, and a positioning groove is provided at the bottom of the placement seat 312. When placing the placement seat 312, the placement seat 312 is directly placed on the top of the rotating rod 311, and the positioning pin is inserted into the positioning groove.

[0052] In order to further improve the stability of the stator 7 placed on the placement seat 312, a positioning column and a plurality of positioning rods are provided on the placement seat 312. The positioning column and the positioning rod are vertically installed on the top of the placement seat 312, and the plurality of positioning rods are circumferentially distributed along the axis direction of the positioning column. The stator 7 is provided with a plurality of positioning holes. When the stator 7 is placed on the placement seat 312, the positioning column and the positioning rod are passed through the positioning holes. The positioning column and the positioning rod pass through the positioning holes to improve the stability of the stator 7 during rotation or movement.

[0053] The pressing member 32 comprises a pressing frame 321 and a pressing rod 322. The pressing frame 321 is mounted on the workbench 1 and moves in the vertical direction with the workbench 1. A cylinder is provided on the pressing frame 321. When the pressing frame 321 needs to be moved, the pressing frame 321 can be pushed by the cylinder to move in the vertical direction.

[0054] The lower pressing rod 322 is installed on the lower pressing frame 321, and the lower pressing rod 322 penetrates the lower pressing frame 321. The lower pressing rod 322 rotates with the lower pressing frame 321 and slides with the lower pressing frame 321 in the vertical direction. After the stator 7 is placed on the placement seat 312, the lower pressing frame 321 drives the lower pressing rod 322 to contact the top of the positioning column. In order to improve the contact stability between the lower pressing rod 322 and the placement column, the top of the placement column is provided with a plug-in slot, and the bottom of the lower pressing rod 322 is integrally formed with a plug-in block 323, and the plug-in block 323 and the plug-in slot are plugged in. The rotating rod 311 drives the placement seat 312, the stator 7 and the lower pressing rod 322 to rotate synchronously.

[0055] In order to reduce the possibility that the lower pressing rod 322 will damage the positioning column during the pressing process, a spring is sleeved on the lower pressing rod 322. The lower pressing rod 322 is pressed tightly against the placement column under the pressure of the spring. The spring buffers the pressure applied by the lower pressing frame 321, reducing the possibility of excessive force on the placement seat 312 and damage.

[0056] The pick-up and delivery mechanism 2 includes a pick-up and delivery frame 21 and a pick-up and delivery clamp 22. The pick-up and delivery frame 21 is installed on the workbench 1, and the pick-up and delivery frame 21 and the workbench 1 move relative to each other on the horizontal plane. A lead screw module is provided between the pick-up and delivery frame 21 and the workbench 1, and the lead screw module is used to move the pick-up and delivery frame 21 along a specific route on the horizontal plane.

[0057] The pick-up and delivery clamp 22 is installed on the pick-up and delivery frame 21, and the pick-up and delivery clamp 22 clamps the placement seat 312. In order to improve the stability of the pick-up and delivery clamp 22 clamping the placement seat 312, a pick-up and delivery groove is opened on the side wall of the placement seat 312, so that the cross section of the placement seat 312 is set to be elliptical. When clamping the placement seat 312, the pick-up and delivery clamp 22 is inserted into the pick-up and delivery groove, and the inner wall of the placement seat 312 is clamped, thereby improving the stability and convenience of clamping the placement seat 312. The stator 7 is placed on the placement seat 312 in advance, and then the placement seat 312 can be carried by the pick-up and delivery assembly, thereby improving the convenience of carrying the stator 7.

[0058] The wire arrangement mechanism 4 includes a positioning seat 41, a longitudinal guide claw 42 and a lateral guide claw 43. The positioning seat 41 is installed at a position of the winding mechanism 5 close to the winding fixture 3, the longitudinal guide claw 42 is installed at the top and bottom of the mounting seat, and the lateral guide claw 43 is installed on the side of the mounting seat. After the stator 7 is placed on the placement seat 312, the positioning seat 41 is in contact with the side wall of the stator 7, and the longitudinal guide claw 42 is clamped at the top and bottom of the stator 7. The lateral guide claw 43 includes a first guide claw 431 and a second guide claw 432.

[0059] A pair of the first guide claw 431 and the second guide claw 432 are provided. A positioning frame 433 is provided under the first guide claw 431. The positioning frame 433 and the workbench 1 move in the vertical direction and the horizontal direction. A transverse cylinder and a longitudinal cylinder are provided between the positioning frame 433 and the workbench 1. The positioning frame 433 moves by the cooperation of the transverse cylinder and the longitudinal cylinder, thereby driving the movement of the first guide claw 431. After the stator 7 is placed on the placement seat 312, the first guide claw 431 is moved by the longitudinal cylinder and the transverse cylinder, so that the stator 7 is placed between the first guide claw 431 and the positioning frame 433, and the end of the first guide claw 431 close to the stator 7 is placed outside the wire inlet of the stator 7 slot.

[0060] The second guide claws 432 are respectively installed on both sides of the positioning seat 41. The side of the second guide claw 432 close to the stator 7 is located inside the wire entry port of the stator 7 slot. The first guide claw 431 and the second guide claw 432 cooperate with each other to form a smooth wire entry channel. In order to further facilitate the smooth entry into the stator 7 slot, the first guide claw 431 and the second guide claw 432 are tilted at one end close to the stator 7 to guide the wire into the stator 7 slot. In order to further improve the placement stability of the stator 7, a positioning cylinder 434 is provided on the positioning frame 433. After the stator 7 is placed on the placement seat 312, the positioning cylinder 434 and the positioning seat 41 cooperate with each other to clamp the side wall of the stator 7 together, thereby improving the stability of the stator 7.

[0061] The wire cutting mechanism 6 includes a wire cutting assembly 61, a wire clamping assembly 62 and a collection box 63. The wire clamping assembly 62 includes a wire clamp 621 and a paddle 622. The wire clamp 621 clamps the wire and controls the clamping force on the wire. When the wire needs to be cut, the wire is clamped by the wire clamp 621, and then the wire is cut by the wire cutting assembly 61. Then, the wire clamp 621 is released to make the wire fall into the collection box 63.

[0062] The paddle 622 is mounted on the wire clamp 621 and moves relative to the wire clamp 621 in the vertical direction. A toggle cylinder is provided between the paddle 622 and the wire clamp 621. The paddle 622 is driven by the toggle cylinder to move. The paddle 622 pushes the disconnected wire to move during the movement, so as to drop the wire into the collection box 63. In order to reduce the influence of the collection box 63 on the winding of the stator 7 while facilitating the collection of the disconnected wire, a feed pipe 631 is provided on the collection box 63. The feed pipe 631 is pushed by the waste cylinder to move in the vertical direction. When waste needs to be collected, the feed pipe 631 is moved close to the wire clamp 621. After the collection is completed, the feed pipe 631 is moved to a position away from the wire clamp 621 again.

[0063] The implementation principle of a stator winding machine in an embodiment of the present application is as follows: first, the stator 7 to be wound is placed on the winding fixture 3 by the pick-up and delivery mechanism 2. Next, a smooth wire entry channel is formed at the slot of the stator 7 by the wire arrangement mechanism 4 to prepare for winding. Then, the winding mechanism 5 throws the wire from the wire entry channel into the slot of the stator 7 and winds it around the stator 7. During this process, the winding fixture 3 drives the stator 7 to rotate to cooperate with the winding. When it is necessary to cut the wire, the wire breaking mechanism 6 will intervene, cut the wire through the wire cutting assembly 61, and collect the cut wire through the collection box 63. After the winding is completed, the pick-up and delivery mechanism 2 will remove the stator 7 that has been wound again, and place the new stator 7 to be wound on the winding fixture 3, and repeat this cycle to realize the automation of the stator 7 winding work. During the whole process, the placing member 31 and the pressing member 32 of the winding fixture 3 ensure the stability of the stator 7, while the longitudinal guide claws 42 and the lateral guide claws 43 of the wire arrangement mechanism 4 ensure that the wires can smoothly enter the slots of the stator 7. The wire clamp 621 and the paddle 622 of the wire breaking mechanism 6 are responsible for cutting and collecting the wires, ensuring a smooth and neat workflow.

[0064] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
