A box cover 602 is arranged on the top of the cleaning box 601, so that the cleaning liquid can be prevented from spilling out of the top of the cleaning box 601 as much as possible during the cleaning process of the enameled wire.

[0030] As shown in Figure 9 , two first cleaning rollers 603 are installed in the cleaning box 601, and a second cleaning roller 604 is arranged between the two first cleaning rollers 603. The first cleaning roller 603 and the second cleaning roller 604 are both rotatably connected to the bottom wall of the inner cavity of the cleaning box 601 through a support structure. Before winding, the enameled wire needs to pass through the cleaning box 601 and be brushed by the first cleaning roller 603 and the second cleaning roller 604 installed in the cleaning box 601 to clean the surface of the enameled wire. When the enameled wire passes through the cleaning box 601, the first cleaning roller 603 and the second cleaning roller 604 can be driven to rotate by friction, so that the cleaning liquid in the cleaning box 601 can impact the first cleaning roller 603 and the second cleaning roller 604 to wash away the dust and impurities adhered to the first cleaning roller 603 and the second cleaning roller 604, so as to avoid that the impurities adhered to the first cleaning roller 603 and the second cleaning roller 604 are washed and adhered to the enameled wire.

As shown in Figure 10 and Figure 11 As shown, a through hole 702 is formed on the top of the water collecting tank 701, a fourth gear 703 is fixedly sleeved on the middle segment of the rotating shaft 704, the fourth gear 703 penetrates the top wall of the water collecting tank 701 through the through hole 702 and is engaged with the third gear 504, the diameter of the fourth gear 703 is smaller than that of the third gear 504, so that the third gear 504 can drive the fourth gear 703 to rotate quickly when the third gear 504 rotates, the dehydration hole 707 is formed on the rotating shaft 704 of the side of the sponge cylinder 706, the third motor 501 drives the transmission shaft 502 to rotate during the winding process, so as to drive the fourth gear 703 to rotate at high speed through the third gear 504, and the centrifugal force generated by the rotation can make the cleaning liquid adsorbed in the sponge cylinder 706 be thrown out through the dehydration hole 707, so as to dehydrate the sponge cylinder 706, thereby enabling the sponge cylinder 706 to continuously adsorb and wipe the residual cleaning liquid on the enameled wire. As shown in Figure 9 As shown, the water collecting tank 701 is communicated with a drain pipe 708 at the bottom, one end of the drain pipe 708 away from the dehydration hole 707 penetrates the side wall of the drain pipe 605 and is communicated with the inside of the drain pipe 605, the cleaning liquid thrown and dehydrated by the sponge cylinder 706 falls in the water collecting tank 701 and is conveyed to the drain pipe 605 along the drain pipe 708 under the action of gravity, and is discharged through the drain pipe 605.

[0035] When winding, the motor stator can be placed in the stator positioning frame 301, and the first motor 202 is driven to rotate the turntable 203 until the first gear 304 installed below the stator positioning frame 301 rotates to mesh with the second gear 306, at which time one of the stator slots of the motor stator corresponds to the wire tube 405, then the first cylinder 802 adjusts the pneumatic clamping jaw 803 to the set position, at the same time, the second cylinder 804 drives the pneumatic clamping jaw 803 to close to fix the end of the enameled wire outside the wire tube 405, after the end of the enameled wire is clamped and fixed, the electric telescopic rod 403 is started to cycle to extend and retract, 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, cooperating with the first gear 304 to drive the motor stator to swing synchronously, realizing automatic winding of the enameled wire on the inner teeth between the two stator slots of the motor stator, when one of the inner teeth is wound, the second motor 305 drives the second gear 306 to rotate by a set angle, rotating the other inner tooth to below the wire tube 405, so as to cycle, winding the multiple inner teeth of the motor stator.

[0036] Since the stator positioning frame 301 is provided with multiple stators, when the stator in one stator positioning frame 301 is completely wound, the first motor 202 is driven to rotate the turntable 203 to rotate the subsequent stator positioning frame 301 to the winding station for winding, and when winding, the user can unload the motor stator after winding, and reload the stator positioning frame 301 after unloading, saving a lot of time and greatly improving the winding efficiency of the motor stator.

[0038] The enameled wire needs to pass through the cleaning box 601 before winding, and 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, and when the enameled wire passes through the cleaning box 601, the first cleaning roller 603 and the second cleaning roller 604 can be driven to rotate by friction, so that the cleaning liquid in the cleaning box 601 impacts the first cleaning roller 603 and the second cleaning roller 604, and the dirt and impurities adhered to the first cleaning roller 603 and the second cleaning roller 604 are washed clean, so as to avoid the impurities adhered to the first cleaning roller 603 and the second cleaning roller 604 from being washed and adhered to the enameled wire.

[0039] After the enameled wire passes out of the cleaning box 601, the sponge barrel 706 installed in the rotating shaft 704 is used for wiping, so as to avoid the problem that the cleaning liquid remaining on the enameled wire affects subsequent winding; The middle section of the rotating shaft 704 is fixedly sleeved with the fourth gear 703, the top of the fourth gear 703 is engaged with the third gear 504 installed on the transmission shaft 502, the dehydration hole 707 is formed in the rotating shaft 704 on the side of the sponge barrel 706, when the third motor 501 drives the transmission shaft 502 to rotate during winding, the fourth gear 703 can be driven to rotate at high speed by the third gear 504, and the cleaning liquid adsorbed in the sponge barrel 706 is thrown out of the dehydration hole 707 by the centrifugal force generated by the rotation, so as to dehydrate the sponge barrel 706, so that the sponge barrel 706 can continuously adsorb and wipe the cleaning liquid remaining on the enameled wire.
