[0022] The present invention will be further described in detail below in conjunction with the accompanying drawings.

[0023] Reference Figure 1 to Figure 6 A motor stator wire frame winding machine includes a frame 1, a feeding device 2, a winding device 3, a wire drawing device 4 and a rotating device 5. The feeding device 2, the winding device 3 and the wire drawing device 4 are all arranged on the frame. The feeding device 2 is arranged on one side of the winding device 3 and corresponds to the winding device 3. The wire drawing device 4 is located below the winding device 3 and is arranged corresponding to the winding device 3. The rotating device 5 includes a rotating motor 51 and a rotating shaft 52. The rotating motor 51 is arranged on the frame 1. The rotating shaft 52 is arranged on the frame 1 and is connected to the output shaft of the rotating motor 51. The rotating shaft 52 corresponds to the winding device 3. Among them, the outer diameter of the rotating shaft 52 is consistent with the aperture of the stator wire frame, so that the stator wire frame can be fixed on the rotating shaft 52 and rotate together with the rotating shaft 52. In actual use, an enameled wire rack 8 is installed at the rear end of the frame 1 to facilitate the installation and guidance of the enameled wire. The enameled wire is pulled from one side of the enameled wire rack 8 to the winding device 3 for winding. When winding, the rotating motor 51 rotates, and then drives the rotating shaft 52 to rotate, so that the stator wire rack on the rotating shaft 52 rotates, and then the enameled wire can be wound on the motor stator wire rack 10 (such as Figure 7 Winding is performed on the surface as shown).

[0024] During the production process, the motor stator bobbin is transported to the winding device 3 by the feeding device 2, and the stator bobbin is sleeved on the rotating shaft 52 to realize the loading of the stator bobbin; then, the enameled wire is pulled to one side of the stator bobbin on the rotating shaft 52 by the wire pulling device 4, and then one end of the enameled wire is first wound on one of the pin terminals 101 of the stator bobbin by the winding device 3, and then the wire pulling device 4 releases the enameled wire, and the winding device 3 winds the wire slots of the stator bobbin; when the winding of the wire slots of the stator bobbin is completed, the enameled wire is pulled off by the wire pulling device 4 to complete the winding; finally, the wound product is taken out from the rotating shaft 52 by the feeding device 2 to complete the unloading.

[0025] The feeding device 2 includes a feeding rack 21, a movable rack 22, a first up-and-down moving assembly 23 and a first front-and-back moving assembly 24. The movable rack 22 is arranged on one side of the feeding rack 21. The first up-and-down moving assembly 23 includes a first lifting cylinder 231. The piston rod of the first lifting cylinder 231 is connected to the movable rack 22. The first front-and-back moving assembly 24 includes a first front-and-back moving cylinder 241. The cylinder body of the first front-and-back moving cylinder 241 is arranged on the frame 1, and the piston rod is connected to the movable rack 22.

[0026] Among them, the front side of the frame 1 is provided with a feeding guide rail 7 and a feeding motor, the feeding guide rail 7 is arranged horizontally on the left and right, the feeding motor is arranged at one end of the feeding guide rail 7, one end of the feeding frame 21 is matched with the feeding guide rail 7, a threaded rod is connected to the output shaft of the feeding motor, and the feeding frame 21 is threadedly matched with the threaded rod. Therefore, by driving the threaded rod to rotate through the feeding motor, the feeding frame 21 can be driven to move along the feeding guide rail 7; by controlling the rotation direction of the feeding motor, the moving direction of the feeding frame 21 can be controlled.

[0027] The other end of the feeding frame 21 is provided with a plurality of insertion rods 211, the outer diameter of each insertion rod is consistent with the aperture of the stator bobbin, and the stator bobbin to be wound can be sleeved on the insertion rods 211. The stator bobbin to be processed is distributed at intervals on the insertion rods 211, so that the stator bobbin can also be sleeved on the insertion rods 211 at intervals after subsequent winding, so that the stator bobbin to be processed and the processed stator bobbin do not affect each other, thereby shortening the loading and unloading time of the stator bobbin on the winding device 3, which is conducive to improving production efficiency.

[0028] The motor stator wire winding machine also includes a guide rod 6, and the movable frame 22 includes a first mounting frame 221, a lifting plate 222 and a push plate 223. The guide rod 6 is arranged on the frame 1 and is arranged parallel to the piston rod of the first forward and backward moving cylinder 241. The first mounting frame 221 is arranged on the frame 1, and the guide rod 6 passes through the first mounting frame 221. The piston rod of the first forward and backward moving cylinder 241 is connected to the first mounting frame 221. The lifting plate 222 is arranged above the first mounting frame 221. The cylinder body of the first lifting cylinder 231 is arranged on the first mounting frame 221, the piston rod is connected to the lifting plate 222, and the push plate 223 is arranged on the lifting plate 222.

[0029] When the moving frame 22 needs to move forward and backward, the piston rod of the first forward and backward moving cylinder 241 is extended and retracted, driving the first mounting frame 221 to move forward and backward, thereby driving the lifting plate 222 and the push plate 223 to move forward and backward together. The first lifting cylinder 231 can drive the lifting plate 222 to move up and down, thereby driving the push plate 223 to move up and down.

[0030] The feeding device 2 further includes a first left-right moving assembly 25, which includes a first left-right moving cylinder 251 and a first left-right transverse slide rail 252. The first left-right transverse slide rail 252 is arranged on the lifting plate 222, the bottom of the push plate 223 cooperates with the first left-right transverse slide rail 252, the cylinder body of the first left-right moving cylinder 251 is fixed on the lifting plate 222, and the piston rod is connected to the push plate 223. Therefore, through the first left-right transverse slide rail 252, the push plate 223 can be pushed along the first left-right transverse slide rail 252 by the first left-right moving cylinder 251.

[0031] Specifically, when there is no stator wire frame on the push plate 223, the piston rod of the first forward and backward moving cylinder 241 extends, pushing the first mounting frame 221 forward, thereby driving the push plate 223 forward and moving it to the bottom of the insertion rod 211 of the feeding frame 21; then, the piston rod of the first lifting cylinder 231 extends, pushing the push plate 223 upward, clamping the stator wire frame on the insertion rod 211 on the push plate 223. Then, the piston rod of the first forward and backward moving cylinder 241 pulls back, driving the push plate 223 to move toward the side of the rotating shaft 52 until the stator wire frame is inserted into the rotating shaft 52; the first lifting cylinder 231 pulls back, pulling the push plate 223 downward. Similarly, when the winding of the stator bobbin on the rotating shaft 52 is completed, the push plate 223 is pushed to the bottom of the rotating shaft 52 by the first forward and backward moving cylinder 241, and then the push plate 223 is pushed upward by the first lifting cylinder 231, so that the stator bobbin after winding can fall into the push plate 223; then, the first forward and backward moving cylinder 241 pushes the push plate 223 forward, so that the processed stator bobbin on the push plate 223 is inserted into the insertion rod 211.

[0032] In order to improve the efficiency of loading and unloading the stator bobbin and reduce the time difference between loading and unloading, when the stator bobbin on the rotating shaft 52 is being wound, the stator bobbin to be processed is pre-inserted on the insertion rod 211 of the feeding rack 21; and when the stator bobbin on the rotating shaft 52 is unloaded, the first left-right moving cylinder 251 drives the push plate 223 to move to one side, and after the push plate 223 moves, the stator bobbin arranged at intervals on the insertion rod 211 can be placed on the push plate 223, and then the rotating shaft is loaded. In this way, the loading and unloading time is greatly saved, thereby improving the winding efficiency of the winding device.

[0033] The push plate 223 is provided with a plurality of material slots 224, which are square in shape, and the width of the openings 225 at the front and rear ends of the material slots 224 is smaller than the width of the middle of the material slots 224. The number of the material slots 224 is consistent with the number of the insertion rods 211, so that when loading, the stator bobbins to be wound on the insertion rods 211 are spaced apart on the material slots 224; when the stator bobbins on the rotating shaft 52 are wound, the material push plate 223 is moved to the left or right side, so that the processed stator bobbins can be unloaded to the dislocated material slots 224, so that the wound and unwound stator bobbins are spaced apart on the push rods.

[0034] By providing a material trough 224, and the width of the openings 225 at both ends is smaller than the width of the middle of the material trough 224, when the pushing plate 223 is pushed upward, the stator wire frame on the insertion rod 211 or the rotating shaft 52 can be inserted into the material trough 224, and then the stator wire frame can be separated from the insertion rod 211 or the rotating shaft 52 by moving the pushing plate 223 backward or forward, thereby realizing automatic loading and unloading of the stator wire frame.

[0035] The wire pulling device 4 includes a rotating frame 41, a rotating motor 42 and a chuck 43. There are multiple chucks 43, all of which are arranged on the rotating frame 41. The rotating frame 41 is arranged on the frame 1. The rotating motor 42 is arranged on the frame 1. The rotating frame 41 is connected to the output shaft of the rotating motor 42. The chuck 43 corresponds to the winding device 3. Among them, the chuck 43 can be a pneumatic finger cylinder, which is convenient for clamping and loosening the enameled wire. The rotating frame 41 can be driven to rotate by the rotating motor 42, so that the chuck on the rotating frame 41 rotates with the rotating frame 41. The chuck 43 corresponds to the rotating shaft 52 one by one, which is convenient for each stator wire frame to be wound. The enameled wire after winding can be pulled off by the chuck 43.

[0036] The wire pulling device 4 also includes a base plate 44, a second mounting frame 45, a second front-to-rear moving assembly 46 and a second left-to-right moving assembly 47. The second mounting frame 45 is arranged on the base plate 44, the rotating frame 41 is arranged on the second mounting frame 45, the second front-to-rear moving assembly 46 includes a second front-to-rear moving cylinder 461, the second front-to-rear moving cylinder 461 is arranged on the frame 1, the piston rod is connected to the base plate 44, the base plate 44 is provided with a second left-to-right transverse slide rail 441, the bottom of the second mounting frame 45 is arranged on the second left-to-right transverse slide rail 441, the second left-to-right moving assembly 47 includes a second left-to-right moving cylinder 471, the cylinder body of the second left-to-right moving cylinder 471 is arranged on the base plate 44, the piston rod is connected to the second mounting frame 45, and the shell of the rotating motor 42 is installed on the second mounting frame 45.

[0037] Since the front and rear ends of the stator bobbin are both plugged with pin terminals, and both the front and rear ends have two or three pins, it is necessary to wind the enameled wire around each pin. Specifically, after the rotating shaft 52 is loaded, the piston rod of the second forward and backward moving cylinder 461 extends, driving the bottom plate 44 to move forward, thereby driving the second mounting frame 45 and the rotating frame 41 to move forward, and the chuck 43 moves forward together. When the chuck moves to the front side of the stator bobbin, the rotating motor 42 drives the rotating motor 42 and the chuck 43 to rotate together, so that the chuck 43 is in a vertical state. At this time, one end of the enameled wire pulled out from the winding device 3 is clamped by the chuck 43; under the clamping action of the chuck 43, the enameled wire is pulled by the winding device 3, and the enameled wire is wound around one of the pins at the front end of the stator bobbin, thereby realizing the winding of the enameled wire on the pin. Subsequently, the clamp 43 is released, the rotary motor 42 drives the clamp 43 to rotate, the winding device 3 starts to wind on the bobbin of the stator bobbin, and the clamp 43 rotates downward to avoid interfering with the winding of the enameled wire on the stator bobbin.

[0038] After the winding of the wire grooves of the stator bobbin and the front and rear end pins is completed, the enameled wire needs to be clamped off. In the actual production process, in order to improve production efficiency, when the winding device 3 is winding the pins at the rear end of the stator bobbin, the rotating motor 42 drives the clamp 43 to rotate to a vertical state, and pulls back through the second forward and backward moving cylinder 461, driving the rotating frame 41 to move backward and move to the rear side of the stator bobbin on the rotating shaft 52 to avoid interfering with the winding of the winding device. When the winding of the stator bobbin is completed, the second forward and backward moving cylinder 461 extends forward, pushes the clamp 43 to move to the side of the pin at the rear end of the stator bobbin, and then clamps the enameled wire pulled out by the winding device 3; then the piston rod of the second left and right moving cylinder 471 extends, pushes the second mounting frame 45 and the clamp 43 to move to the side away from the corresponding stator bobbin, so that the enameled wire is broken, and the winding of the stator bobbin is completed. Finally, the feeding device 2 is used for unloading, and then the next stator bobbin is loaded and wound. The overall structure is compact and the position distribution is reasonable, which can greatly improve the production efficiency of the product, and each structure does not affect each other when working, shortening the waiting time during processing.

[0039] The winding device 3 includes a winding frame 31, which is provided with a wire hole 313, the wire hole 313 corresponds to the rotating shaft 52, and the winding frame 31 is located above the rotating shaft 52. The wire hole can facilitate the pulling out of the enameled wire, and a pull head can be installed below the wire hole to facilitate tightening the enameled wire.

[0040] The winding device 3 also includes an adjustment frame 32 and a telescopic cylinder 33. The adjustment frame 32 is located above the winding frame 31. The cylinder body of the telescopic cylinder 33 is arranged on the winding frame 31. The piston rod is connected to the adjustment frame 32. The adjustment frame 32 is provided with a guide wheel, and the guide wheel corresponds to the wire hole. The enameled wire passes through the guide wheel and is then pulled to the wire hole on the winding frame 31. The guide wheel can play a stretching and guiding role on the enameled wire, so that the enameled wire can be evenly wound on the stator wire frame.

[0041] Since two pins are provided at the front and rear ends of the stator bobbin, when the enameled wire is wound on the pin, in order to ensure that the enameled wire has enough margin, the piston rod of the telescopic cylinder 33 is pulled down, so that the distance between the guide wheel on the adjustment frame 32 and the wire hole on the winding frame 31 is shortened, thereby making the enameled wire in a relaxed state, which is convenient for the winding device 3 to wind on the pin. After the winding on the pin is completed, the piston rod of the telescopic cylinder 33 is pushed out, and the distance between the guide wheel and the wire hole is increased, so that the enameled wire is in a tensioned state, which is convenient for the winding of the enameled wire on the wire groove of the stator bobbin.

[0042] The winding device 3 also includes a third front-to-back moving component 34, a third left-to-right moving component 35 and a lifting component 36. The third front-to-back moving component 34 includes a front-to-back longitudinal slide rail 341, a front-to-back moving motor 342 and a front-to-back moving plate 343. The third left-to-right moving component 35 includes a third left-to-right transverse slide rail 351, a left-to-right moving motor and a left-to-right moving plate 353. The lifting component 36 includes a vertical slide rail 361 and a lifting motor 362. The front-to-back longitudinal slide rail 341 is arranged on the frame 1, the front-to-back moving plate 343 cooperates with the front-to-back longitudinal slide rail 341, the front-to-back moving motor 342 is connected to the front-to-back moving plate 343, the third left-to-right transverse slide rail 351 is arranged on the front-to-back moving plate 343, the left-to-right moving plate 353 is arranged on the third left-to-right transverse slide rail 351, the left-to-right moving motor is connected to the left-to-right moving plate 353, the vertical slide rail 361 is arranged at the front end of the left-to-right moving plate 353, one side of the winding rack 31 cooperates with the vertical slide rail 361, and the output shaft of the lifting motor 362 is connected to the winding rack 31.

[0043] Specifically, the output shaft of the forward and backward moving motor 342 is connected to the forward and backward moving plate 343 through the first screw rod, and the forward and backward moving plate 343 is threadedly matched with the first screw rod, so that the forward and backward moving motor 342 can accurately control the forward and backward moving distance of the forward and backward moving plate 343. Similarly, the output shaft of the left and right moving motor is connected to the left and right moving plate 353 through the second screw rod, so as to accurately control the left and right moving distance of the left and right moving plate 353; the lifting motor 362 is connected to the winding frame 31 through the third screw rod, so as to accurately control the up and down moving distance of the winding frame 31.

[0044] When the front-back moving motor 342 is working, the front-back moving plate 343 can be driven to move forward or backward along the front-back longitudinal slide rails 341, and the third left-right transverse slide rails 351 and the left-right moving plate 353 can be driven to move forward or backward through the front-back moving plate 343, and the vertical slide rail 361 and the winding frame 31 can be driven to move forward or backward through the left-right moving slide plate 353; that is, the front-back movement of the winding frame 31 can be realized through the front-back moving motor 342. When the left-right moving motor is working, the left-right moving plate 353 can be driven to move left-right along the third left-right transverse slide rails 351, and the vertical slide rail 361 and the winding frame 31 can be driven to move left-right through the left-right moving plate 353. When the lifting motor 362 is working, the winding frame 31 can be driven to move up and down along the vertical slide rail 361.

[0045] The specific winding process of the winding device 3 is as follows:

[0046] When the clamp 43 is located on one side of the front end of the stator bobbin on the rotating shaft 42 and clamps the enameled wire, the winding frame 31 is also located on one side of the front end of the stator bobbin. The left and right moving motor drives the winding frame 31 to move to one side of the stator bobbin, and the enameled wire is close to one of the pins at the front end of the stator bobbin; at this time, the adjustment frame 32 moves downward. After the winding frame 31 moves into place, the front and back moving motor 342 and the left and right moving motor are linked to drive the winding frame 31 to move forward and backward and left and right, so that the enameled wire is wound on one of the pins. After one end of the enameled wire is wound on the pin for multiple turns and fixed, the clamp 43 releases the enameled wire and rotates downward; the rotating motor drives the rotating shaft 42 to rotate, so that the enameled wire is wound on the wire slot of the stator bobbin. At the same time, the front and back moving motor 342 drives the winding frame 31 to move forward and backward, so that the enameled wire is wound on the entire wire slot.

[0047] After the enameled wire is wound back and forth on the wire slot of the stator wire frame for multiple turns, the forward and backward moving motor 342 moves to the side of the pin at the front end of the stator wire frame, and then the left and right moving motor pushes the winding frame 31 to move to the side of the pin on the right. After the winding frame 31 moves to the side of another pin at the front end of the stator wire frame, the forward and backward moving motor 342 and the left and right moving motor are linked to drive the winding frame 31 to move forward and backward and left and right, so that the enameled wire is wound on the pin; and then continue to wind on the wire slot. After the winding on the pin at the front end of the stator wire frame is completed, after the winding frame has wound the corresponding number of turns on the wire slot, the forward and backward moving motor 342 drives the winding frame 31 to move to the side of the pin at the rear end of the stator wire frame 31, and the same operation is performed to realize the winding of the pin at the rear end of the stator wire frame 31. Among them, when the winding frame is winding the pin, the rotating motor 51 stops rotating, that is, the rotating shaft 52 stops rotating, which facilitates the winding of the enameled wire on the pin.

[0048] When the winding is completed on the wire slots and pin terminals of the stator bobbin, the left-right moving motor pushes the bobbin 31 to move toward the side of the clamp 43, and the clamp 43 clamps the enameled wire moved by the bobbin, and moves to the side away from the stator bobbin under the action of the second left-right moving cylinder 471, so that the enameled wire is pulled off by the clamp 43, so that the enameled wire on the bobbin is separated from the stator bobbin, the winding is completed, and the rotating motor 51 stops rotating. Then, the material is unloaded through the push plate, and the unwound stator bobbin is loaded, and the winding is repeated.

[0049] In actual use, a motor stator wire frame winding machine of the present invention also includes a flip cylinder 9, the winding frame 31 includes a frame 311 and a winding plate 312, the frame 311 is arranged on a vertical slide rail 361, the two ends of the winding plate 312 are arranged on the frame 311, and are rotatably connected to the frame 311, the wire hole and the pull head are both arranged on the winding plate 312, and the winding plate 312 can be moved forward and backward, left and right, and up and down together through the frame 311; there are two flip cylinders 9, which are respectively arranged on both sides of the frame 311, and the flip cylinder 9 is tilted on the frame 311, and the piston rod of the flip cylinder 9 is connected to the two ends of the winding plate 312. The winding plate 312 can be driven to rotate by the extension and contraction of the piston rod of the flip cylinder 9. As described above, the rotating shaft 52 is in a horizontal state, and when the stator wire frame is horizontally inserted into the rotating shaft 52, the piston rod of the flip cylinder 9 is in an extended state, so that the wire hole is vertically downward, and the pull head is located directly below the wire hole.

[0050] In summary, the motor stator bobbin winding machine of the present invention can realize automatic loading and unloading and automatic winding of the motor stator bobbin through the joint action of the feeding device 2, the winding device 3, the wire pulling device 4 and the rotating device 5, without the need for manual operation, thus saving manpower and greatly improving production efficiency.

[0051] The above are only preferred embodiments of the present invention. It should be pointed out that a person skilled in the art can make several modifications and improvements without departing from the inventive concept of the present invention, and these all fall within the protection scope of the present invention.
