A fourth gear that meshes with the third gear is fixedly sleeved in the middle section of the rotating shaft. When the third motor drives the transmission shaft to rotate and assist in winding, the third gear can drive the rotating shaft to rotate at high speed through the fourth gear. The centrifugal force is used to dehydrate the sponge tube, so that the sponge tube can continuously absorb and wipe the residual cleaning solution on the enameled wire.

[0032] The present application will now be described in further detail with reference to the accompanying drawings. It should be noted that the following specific embodiments are only used to further illustrate the present application and should not be construed as limiting the scope of protection of the present application. Those skilled in the art can make some non-essential improvements and adjustments to the present application based on the above application content. Example 1

[0033] like Figure 1 and Figure 2As shown, a stator winding machine includes a housing 101, which is hollow inside. An inspection port is provided on one side wall of the housing 101. A support frame 102 is fixedly connected to the upper surface of one end of the housing 101. A reinforcing rib is provided on the support frame 102 to increase the stability of the support frame 102. A horizontally arranged cross plate 103 is installed at the top of the support frame 102. A sliding groove 104 is provided on the free end of the cross plate 103, and a sliding hole is provided on the bottom wall of the sliding groove 104.

[0034] like Figure 4 and Figure 5 As shown, a first motor 202 is provided in the inner cavity of the chassis 101. The first motor 202 is fixedly connected to the top wall of the inner cavity of the chassis 101 through the motor mounting base 201. The output end of the first motor 202 passes through the top wall of the chassis 101 and is connected to the rotating rod of the top wall of the chassis 101. A turntable 203 is fixedly connected to the output end of the first motor 202. Multiple connecting seats 204 fixedly connected to the turntable 203 are distributed in a ring on the turntable 203. When the first motor 202 is started, the turntable 203 and the connecting seats 204 mounted on the turntable 203 can be driven to rotate synchronously through the first motor 202.

[0035] like Figure 5 As shown, a stator positioning frame 301 corresponding to the connecting seat 204 is provided above the turntable 203. An annular flange 302 is integrally formed on the inner wall of the middle section of the stator positioning frame 301. The annular flange 302 is used to support the motor stator, so that the motor stator is suspended in the stator positioning frame 301. A connecting shaft 303 is fixedly connected to the bottom wall of the stator positioning frame 301. The bottom end of the connecting shaft 303 passes through the corresponding connecting seat 204 and is rotatably connected to the connecting seat 204. When the turntable 203 rotates, it can drive the stator positioning frame 301 to rotate and adjust the working position of the stator positioning frame 301.

[0036] like Figure 6 As shown, a second motor 305 is fixedly connected to the inner wall of the chassis 101. The output end of the second motor 305 passes through the top wall of the chassis 101 and is rotatably connected to the top wall of the chassis 101. A second gear 306 is fixedly installed on the output end of the second motor 305, and a first gear 304 is fixedly installed on the bottom end of the connecting shaft 303. The second gear 306 and the first gear 304 mesh with each other. When the user starts the second motor 305, the second gear 306 can be driven to rotate by the second motor 305, which in turn drives the motor stator, which is locked in the stator positioning frame 301, to rotate, thereby adjusting the position of the motor stator. Alternatively, the second gear 306 can be driven to swing by the second motor 305, which in turn drives the motor stator to swing in conjunction with the first gear 304, facilitating subsequent winding work on the motor stator.

[0037] like Figure 7As shown, the top of the support frame 102 is fixedly connected to two ear plates. Each ear plate has an upward-opening support groove. A wire feeding wheel 401 is detachably connected inside the support groove. The wire feeding wheel 401 is used to feed the enameled wire that needs to be wound on the motor stator.

[0038] like Figure 7 As shown, a slider 402 is slidably connected inside the slide groove 104. An electric telescopic rod 403 is fixedly installed on the slider 402. The output end of the electric telescopic rod 403 passes through the bottom wall of the slide groove 104 through a sliding hole and extends to the bottom of the horizontal plate 103. A movable upright plate 404 is fixedly connected to the output end of the electric telescopic rod 403. A wire tube 405 is fixedly inserted through the bottom end of the movable upright plate 404. The wire tube 405 is set perpendicular to the movable upright plate 404. The outer end of the enameled wire passes through the wire tube 405 and extends to the outside of one end of the wire tube 405. The wire tube 405 is made of flexible silicone material to support and protect the enameled wire, and to avoid friction between the enameled wire and the wire tube 405 during winding, which would cause damage to its outer insulating varnish.

[0039] like Figure 3 As shown, a clamping structure for fixing the end of the enameled wire is fixedly installed on the top wall of the housing 101 on the side of the second gear 306 away from the turntable 203. The clamping structure includes a support base 801 fixedly installed on the housing 101. A first cylinder 802 is fixedly installed on the top of the support base 801. A pneumatic gripper 803 is installed on the output end of the first cylinder 802. The first cylinder 802 adjusts the height of the pneumatic gripper 803 by telescoping. A second cylinder 804 is installed on one side of the pneumatic gripper 803 for driving the pneumatic gripper 803 to open or close.

[0040] During winding, the motor stator can be placed inside the stator positioning frame 301, and the turntable 203 is driven to rotate by the first motor 202 until the first gear 304 installed below the stator positioning frame 301 rotates to mesh with the second gear 306. At this time, one of the stator slots of the motor stator corresponds to the conductor tube 405. Then, the pneumatic gripper 803 is adjusted to the set position by the first cylinder 802. At the same time, the second cylinder 804 drives the pneumatic gripper 803 to close and fix the end of the enameled wire outside the conductor tube 405. After the part is clamped and fixed, the electric telescopic rod 403 starts to extend and retract in a cycle, driving the wire tube 405 to move up and down. At the same time, the second motor 305 drives the second gear 306 to swing, which, together with the first gear 304, drives the motor stator to swing synchronously, so as to automatically wind the enameled wire onto the internal teeth between the two stator slots of the motor stator. When one internal tooth is wound, the second motor 305 drives the second gear 306 to rotate at a set angle, rotating the other internal tooth to below the wire tube 405. This cycle is repeated to wind the wire onto multiple internal teeth of the motor stator.

[0041] like Figure 7As shown, in order to ensure that the enameled wire is evenly wound on the internal teeth of the motor stator, a third motor 501 is fixedly installed on the horizontal plate 103. A drive shaft 502 is fixedly connected to the output end of the third motor 501. The middle section of the drive shaft 502 has a reciprocating thread 503. The drive shaft 502 passes through the slider 402 and is screwed to the slider 402 through the reciprocating thread 503. While the wire is being wound on the internal teeth of the motor stator, the third motor 501 starts at the same time, driving the drive shaft 502 to rotate. During the rotation, the drive shaft 502 can drive the electric telescopic rod 403 installed on the slider 402 to slide back and forth under the action of the reciprocating thread 503, so as to achieve even winding of the enameled wire and improve the winding quality of the motor stator.

[0042] like Figure 8 and Figure 9 As shown, a cleaning box 601 is fixedly installed on the horizontal plate 103. The cleaning box 601 contains an appropriate amount of cleaning solution. The top of the cleaning box 601 is provided with a box cover 602, which can minimize the splashing of cleaning solution from the top of the cleaning box 601 during the cleaning of the enameled wire.

[0043] like Figure 9 As shown, two first cleaning rollers 603 are installed inside the cleaning box 601, and a second cleaning roller 604 is arranged between the two first cleaning rollers 603. Both the first cleaning rollers 603 and the second cleaning roller 604 are rotatably connected to the bottom wall of the inner cavity of the cleaning box 601 through a bracket structure. Before winding, the enameled wire needs to pass through the cleaning box 601. The surface of the enameled wire is brushed by the first cleaning rollers 603 and the second cleaning roller 604 installed inside the cleaning box 601. When the enameled wire passes through the cleaning box 601, it can drive the first cleaning rollers 603 and the second cleaning roller 604 to rotate through friction. This causes the cleaning liquid in the cleaning box 601 to impact the first cleaning rollers 603 and the second cleaning roller 604, washing away the dust and impurities adhering to the first cleaning rollers 603 and the second cleaning roller 604, and minimizing the impurities adhering to the first cleaning rollers 603 and the second cleaning roller 604 from being washed onto the enameled wire.

[0044] like Figure 9 As shown, a drain pipe 605 is connected to the bottom of the cleaning tank 601. A solenoid valve 606 is installed at the connection between the drain pipe 605 and the cleaning tank 601. When the cleaning fluid in the cleaning tank 601 contains a large amount of dust and impurities, the solenoid valve 606 can be opened to discharge the cleaning fluid containing a large amount of dust and impurities through the drain pipe 605, making it convenient to replace the cleaning fluid.

[0045] like Figure 7 , Figure 9 , Figure 10 and Figure 11As shown, a third gear 504 is fixedly sleeved on one end of the drive shaft 502 near the third motor 501. A water collection tank 701 is fixedly connected to the horizontal plate 103 below the third gear 504. A rotating shaft 704 rotatably passes through the water collection tank 701. A wire hole 705 is opened on the rotating shaft 704. A cavity is provided inside the rotating shaft 704. A sponge tube 706 is fixedly connected inside the cavity. After the enameled wire is cleaned in the cleaning box 601, it needs to pass through the sponge tube 706. The sponge tube 706 absorbs the residual cleaning liquid on the enameled wire to avoid the residual cleaning liquid affecting the subsequent winding of the enameled wire.

[0046] like Figure 10 and Figure 11 As shown, a through hole 702 is provided on the top of the water collection tank 701. A fourth gear 703 is fixedly sleeved on the middle section of the rotating shaft 704. The top of the fourth gear 703 passes through the through hole 702 through the top wall of the water collection tank 701 and meshes with the third gear 504. The diameter of the fourth gear 703 is smaller than the diameter of the third gear 504, so that when the third gear 504 rotates, it can drive the fourth gear 703 to rotate quickly. A dehydration hole 707 is provided on the rotating shaft 704 on the periphery of the sponge cylinder 706. When the third motor 501 drives the transmission shaft 502 to rotate during the winding process, it can drive the fourth gear 703 to rotate at high speed through the third gear 504. The centrifugal force generated by this rotation is used to throw out the cleaning liquid adsorbed in the sponge cylinder 706 through the dehydration hole 707 to dehydrate the sponge cylinder 706, so that the sponge cylinder 706 can continuously adsorb and wipe the cleaning liquid remaining on the enameled wire.

[0047] like Figure 9 As shown, a drain pipe 708 is connected to the bottom of the water collection tank 701. The end of the drain pipe 708 away from the dehydration hole 707 passes through the side wall of the sewage pipe 605 and is connected to the inside of the sewage pipe 605. The cleaning liquid that the sponge cylinder 706 throws off under the action of centrifugal force falls into the water collection tank 701 and is transported to the sewage pipe 605 along the drain pipe 708 under the action of gravity, and is discharged through the sewage pipe 605.

[0048] A control unit is also fixedly installed on the support frame 102. The control unit is a programmable logic controller (PLC). The PLC controls the overall stator winding machine to work together, which is not only convenient to use, but also greatly improves the winding accuracy and winding efficiency.

[0049] It should be noted that, when using this stator winding machine, firstly, the outer end of the enameled wire wound on the pay-off reel 401 is inserted into the cleaning box 601. The enameled wire is controlled to pass over a first cleaning roller 603 near the pay-off reel 401, then under a second cleaning roller 604, and then over another first cleaning roller 603 and horizontally exit the cleaning box 601. Next, the outer end of the enameled wire is pulled along the wire hole 705 through the rotating shaft 704 and the sponge cylinder 706. Finally, the outer end of the enameled wire is pulled down and passed through the conductor tube 405, thus completing the wiring work of the enameled wire before winding.

[0050] During winding, the motor stator can be placed inside the stator positioning frame 301, and the turntable 203 is driven to rotate by the first motor 202 until the first gear 304 installed below the stator positioning frame 301 rotates to mesh with the second gear 306. At this time, one of the stator slots of the motor stator corresponds to the conductor tube 405. Then, the pneumatic gripper 803 is adjusted to the set position by the first cylinder 802. At the same time, the second cylinder 804 drives the pneumatic gripper 803 to close and fix the end of the enameled wire outside the conductor tube 405. Once fixed in place, the electric telescopic rod 403 starts to extend and retract in a cycle, causing the conductor tube 405 to move up and down. At the same time, the second motor 305 drives the second gear 306 to swing, which, together with the first gear 304, drives the motor stator to swing synchronously, so as to automatically wind the enameled wire onto the internal teeth between the two stator slots of the motor stator. When one internal tooth is wound, the second motor 305 drives the second gear 306 to rotate at a set angle, rotating the other internal tooth to below the conductor tube 405. This cycle is repeated to wind the wire onto multiple internal teeth of the motor stator.

[0051] Since there are multiple stator positioning frames 301, when the stator in one stator positioning frame 301 is completely wound, the turntable 203 can be driven to rotate by the first motor 202 to rotate the subsequent stator positioning frames 301 to the winding station for winding. During winding, the user can unload the wound motor stator and then reload it into the stator positioning frame 301, saving a lot of time and greatly improving the winding efficiency of the motor stator.

[0052] A third motor 501 is fixedly installed on the horizontal plate 103. A drive shaft 502 is fixedly connected to the output end of the third motor 501. A reciprocating thread 503 is provided in the middle section of the drive shaft 502. The drive shaft 502 passes through the slider 402 and is screwed to the slider 402 through the reciprocating thread 503. While the internal teeth of the motor stator are being wound, the third motor 501 is started at the same time, driving the drive shaft 502 to rotate. During the rotation, the drive shaft 502 can drive the electric telescopic rod 403 installed on the slider 402 to slide back and forth under the action of the reciprocating thread 503, so as to achieve uniform winding of the enameled wire and greatly improve the winding quality of the motor stator.

[0053] Before winding, the enameled wire must first pass through a cleaning box 601. The surface of the enameled wire is brushed by the first cleaning roller 603 and the second cleaning roller 604 installed in the cleaning box 601. When the enameled wire passes through the cleaning box 601, the friction force drives the first cleaning roller 603 and the second cleaning roller 604 to rotate, so that the cleaning liquid in the cleaning box 601 impacts the first cleaning roller 603 and the second cleaning roller 604, washing away the dust and impurities adhering to the first cleaning roller 603 and the second cleaning roller 604, and avoiding the impurities adhering to the first cleaning roller 603 and the second cleaning roller 604 from being washed and attached to the enameled wire as much as possible.

[0054] After the enameled wire passes through the cleaning box 601, it is wiped by the sponge tube 706 installed in the shaft 704 to avoid residual cleaning solution on the enameled wire, which may affect subsequent winding.

[0055] A fourth gear 703 is fixedly sleeved in the middle section of the rotating shaft 704. The top of the fourth gear 703 meshes with the third gear 504 installed on the transmission shaft 502. A dehydration hole 707 is opened on the rotating shaft 704 around the sponge cylinder 706. When the third motor 501 drives the transmission shaft 502 to rotate during the winding process, it can drive the fourth gear 703 to rotate at high speed through the third gear 504. The centrifugal force generated by this rotation will throw the cleaning liquid adsorbed in the sponge cylinder 706 out through the dehydration hole 707 to dehydrate the sponge cylinder 706, so that the sponge cylinder 706 can continuously adsorb and wipe the cleaning liquid remaining on the enameled wire.

[0056] The embodiments described above are merely examples of several implementations of the present invention, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the present invention. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of the present invention, and these modifications and improvements all fall within the scope of protection of the present invention.
