[0002] During the production and assembly of the motor stator, it needs to go through multiple processes such as winding, encapsulation and soldering. However, during the assembly of the existing motor stator, each process is completed on different machines. After completing the previous process, it is necessary to manually transfer to the next process, which consumes a lot of manpower and space. At the same time, during the winding process, after the enameled wire is wound on the stator slot, the end of the enameled wire is reserved on the outside, and then the enameled wire is manually wound and fixed on the terminal. Therefore, in this type of processing method, when manually winding, it is necessary to wind the terminal on the wire rack, and when winding, it is necessary to perform multiple actions such as fixing and flipping the wire rack, which requires a lot of manpower, is time-consuming, and has low production efficiency.

[0030] The present invention will be further described in detail below in conjunction with the accompanying drawings.

[0031] Reference Figures 1 to 13The stator automatic assembly line includes a frame 1, a conveying mechanism 2, a winding mechanism 3, a rubber coating mechanism 4 and a tinning mechanism 5. The conveying mechanism 2, the winding mechanism 3, the rubber coating mechanism 4 and the tinning mechanism 5 are arranged in sequence on the frame 1. The frame 1 is provided with a first feeding rack 6, a second feeding rack 7 and a guide rail 11. The first feeding rack 6 is arranged on the guide rail 11 and is located on one side of the conveying mechanism 2 and the winding mechanism 3. The second feeding rack 7 is arranged on the guide rail 11 and is located on one side of the rubber coating mechanism 4 and the tinning mechanism 5. The conveying mechanism 2, the winding mechanism 3, the rubber coating mechanism 4 and the tinning mechanism 5 are all located on the same side of the guide rail 11. Among them, a first feeding motor and a second feeding motor are installed on one side of the guide rail 11. A first conveying belt is wound around the output shaft of the first feeding motor, and a second conveying belt is wound around the output shaft of the second feeding motor. The first feeding rack 6 is clamped on the first conveying belt, and the second feeding rack 7 is clamped on the second conveying belt. The movement of the first feeding rack 6 and the second feeding rack 7 can be conveniently controlled by the first feeding motor and the second feeding motor to meet the use requirements. The guide rail 11 can guide the movement of the first feeding rack 6 and the second feeding rack 7, which is conducive to the smooth movement of the first feeding rack 6 and the second feeding rack 7.

[0032] During production, the automatic stator assembly line of the present invention can be equipped with an automatic pin insertion structure on one side of the conveying mechanism 2, that is, the pins are respectively inserted into the two ends of one side of the stator bobbin by the manipulator in the prior art, so as to facilitate the subsequent winding on the wire slots and pins of the stator bobbin. The stator bobbin after the pin insertion is put into the conveying mechanism 2, and is orderly conveyed to the first feeding rack 6 by the conveying mechanism 2, and then the stator bobbin is conveyed to the winding mechanism 3 by the first feeding rack 6 for winding. After the winding of the wire slots and pins of the stator bobbin is completed by the winding mechanism 3, the wound stator bobbin is conveyed to the rubber coating mechanism 4 by the second feeding rack 7, and the insulating tape is wound on the enameled wire by the rubber coating mechanism 4; finally, it is conveyed to the tinning mechanism 5 by the second feeding rack 7 to complete the soldering, so that the assembly of the stator is completed without manual operation, which greatly saves manpower, reduces the requirements for the space of the production workshop, and ensures the product quality.

[0033] like Figures 1 to 4 As shown, the first feeding rack 6 is provided with a plurality of inserting rods 61, the conveying mechanism 2 comprises a vibration plate 21, a conveying track 22, a stop assembly 23, an inserting assembly 24 and a clamping assembly 25, one end of the conveying track 22 is connected with the vibration plate 21, the stop assembly 23 is arranged at the other end of the conveying track 22, the inserting assembly 24 is located at one side of the other end of the conveying track 22, the clamping assembly 25 is arranged at one side of the inserting assembly 24, and the inserting assembly 24 corresponds to the inserting rod 61. The stator wire frame with the pin terminal is placed in the vibration plate 21, and the stator wire frame can be output in an orderly manner through the conveying track 22 through the vibration of the vibration plate 21.

[0034] The stop assembly 23 includes a lifting cylinder 231 and a stop plate 232. The lifting cylinder 231 is located below the other end of the conveying track 22. The stop plate 232 is connected to the piston rod of the lifting cylinder 231. The clamping assembly 25 includes a front and rear telescopic cylinder 251, an upper and lower telescopic cylinder 252, a pneumatic finger cylinder 253, a front and rear horizontal slide rail 254 and an upper and lower vertical slide rail 255. The frame 1 is provided with a column 12. The cylinder body of the front and rear telescopic cylinder 251 is arranged on the column 12. The piston rod is connected to the front and rear horizontal slide rail 254. The front and rear horizontal slide rail 254 is provided with a front and rear moving frame 256. The upper and lower vertical slide rails 255 are arranged on the front and rear moving frame 256. The upper and lower telescopic cylinders 252 are arranged on the front and rear moving frame 256. The piston rod is connected to the cylinder body of the pneumatic finger cylinder 253. The pneumatic finger cylinder 253 corresponds to the insertion assembly 24 and the insertion rod 61.

[0035] When the stator wire frame on the conveying track 22 is conveyed to the other end, the lifting cylinder 231 drives the stop plate 232 to rise, so that the stop plate 232 moves upward to prevent the product on the conveying track 22 from continuing to be output and prevent the stator wire frame from falling from the conveying track 22. In actual use, a photosensitive switch is installed at the other end of the conveying track 22. When the photosensitive switch senses the stator wire frame, the insertion assembly 24 is activated to insert the stator wire frame at the other end of the conveying track, and then the clamping assembly 25 is activated to clamp the stator wire frame on the insertion assembly 24 to the insertion rod 61 of the first feeding rack.

[0036] When the inserting assembly 24 is inserted out of the stator wire frame on the conveying track, the lifting cylinder 231 pulls the stop plate 232 to move downward, so that there is space on the conveying track, which facilitates the vibration plate 21 to continue to convey the product.

[0037] In order to facilitate the insertion assembly 24 to take out the stator wire frame one by one from the conveying track 22, the insertion assembly 24 includes an insertion rod 241, an insertion forward and backward moving cylinder 242 and an insertion left and right moving cylinder 243, wherein the insertion forward and backward moving cylinder is connected to the piston rod of the insertion left and right moving cylinder, and the insertion rod 241 is connected to the piston rod of the insertion forward and backward moving cylinder, and the insertion rod 241 is moved forward and backward and left and right by the insertion forward and backward moving cylinder and the insertion left and right moving cylinder. Specifically, when the insertion rod 241 needs to take material from the conveying track 22, the insertion left and right moving cylinder pushes the insertion rod 241 to move to one side of the conveying track 22, and the insertion forward and backward moving cylinder pushes the insertion rod 241 to move forward, so that the stator wire frame at the end of the conveying track 22 can be inserted into the insertion rod 241. Subsequently, the insertion rod 241 moves in the opposite direction, driving the stator wire frame to move. At this time, the upper and lower telescopic cylinders 252 of the clamping assembly 25 drive the pneumatic finger cylinder 253 to move downward, and when the pneumatic finger cylinder 253 moves downward to the stator wire frame on the insertion rod 241, the stator wire frame is clamped; then, the front and rear telescopic cylinders 251 push the pneumatic finger cylinder 253 to move forward, and insert the stator wire frame into the insertion rod 61 on the first feeding rack 6. Then, the next stator wire frame is fixed on the first feeding rack 6. Among them, the stator wire frames taken out by the clamping assembly 25 are arranged at intervals on the insertion rod 61, that is, the stator wire frames that are not wound are arranged at intervals on the insertion rod of the first feeding rack 6, and an insertion rod 61 is left between adjacent stator wire frames.

[0038] After the stator bobbin is loaded on the first feeding rack 6, the first feeding rack 6 transports the stator bobbin along the guide rail 11 to the winding mechanism 3 for winding.

[0039] like Figure 1 ,as well as Figures 5 to 10As shown, specifically, the winding mechanism 3 includes a feeding device 31, a winding device 32, a wire pulling device 33 and a rotating device 34. The feeding device 31, the winding device 32 and the wire pulling device 33 are all arranged on the frame. The feeding device 31 is arranged on one side of the winding device 32 and corresponds to the winding device 32. The wire pulling device 33 is located below the winding device 32 and is arranged corresponding to the winding device 32. The rotating device 34 includes a rotating motor 341 and a first rotating shaft 342. The rotating motor 341 is arranged on the frame 1. The first rotating shaft 342 is arranged on the frame 1 and is connected to the output shaft of the rotating motor 341. The first rotating shaft 342 corresponds to the winding device 32. Among them, the outer diameter of the first rotating shaft 342 is consistent with the aperture of the stator bobbin, so that the stator bobbin can be fixed on the first rotating shaft 342 and rotate together with the first rotating shaft 342. 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 32 for winding. When winding, the motor 341 is rotated to drive the first rotating shaft 342 to rotate, so that the stator wire rack on the first rotating shaft 342 rotates, and then the enameled wire can be wound on the motor stator wire rack 10 (such as Fig.14 Winding is performed on the surface as shown).

[0040] During the production process, the motor stator bobbin is transported to the winding device 32 by the feeding device 31, and the stator bobbin is sleeved on the first rotating shaft 342 to realize the loading of the stator bobbin; then, the enameled wire is pulled to one side of the stator bobbin on the first rotating shaft 342 by the wire pulling device 33, 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 32, and then the wire pulling device 33 loosens the enameled wire, and the winding device 32 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 33 to complete the winding; finally, the wound product is taken out from the first rotating shaft 342 by the feeding device 31 to complete the unloading.

[0041] The feeding device 31 includes a moving frame 311, a first up and down moving component 312 and a first front and back moving component 313. The moving frame 311 is arranged on one side of the first feeding frame 6. The first up and down moving component 312 includes a first lifting cylinder 3121. The piston rod of the first lifting cylinder 3121 is connected to the moving frame 311. The first front and back moving component 313 includes a first front and back moving cylinder 3131. The cylinder body of the first front and back moving cylinder 3131 is arranged on the frame 1, and the piston rod is connected to the moving frame 311.

[0042] Since the stator bobbins to be processed are distributed at intervals on the insertion rod 61 of the first feeding rack, the stator bobbins after subsequent winding can also be sleeved on the insertion rod 61 at intervals, so that the stator bobbins to be processed and the processed stator bobbins do not affect each other, thereby shortening the loading and unloading time of the stator bobbins on the winding device 32, which is conducive to improving production efficiency.

[0043] The winding mechanism 3 also includes a guide rod 35, and the movable frame 311 includes a first mounting frame 3111, a lifting plate 3112 and a push plate 3113. The guide rod 35 is arranged on the frame 1 and is arranged parallel to the piston rod of the first forward and backward moving cylinder 313. The first mounting frame 3111 is arranged on the frame 1, and the guide rod 35 passes through the first mounting frame 3111. The piston rod of the first forward and backward moving cylinder 313 is connected to the first mounting frame 3111. The lifting plate 3112 is arranged above the first mounting frame 3111. The cylinder body of the first lifting cylinder 3121 is arranged on the first mounting frame 3111, the piston rod is connected to the lifting plate 3112, and the push plate 3113 is arranged on the lifting plate 3112.

[0044] When the moving frame 311 needs to move forward and backward, the piston rod of the first forward and backward moving cylinder 313 is extended and retracted, driving the first mounting frame 3111 to move forward and backward, thereby driving the lifting plate 3112 and the push plate 3113 to move forward and backward together. The first lifting cylinder 3121 can drive the lifting plate 3112 to move up and down, thereby driving the push plate 3113 to move up and down.

[0045] The feeding device 31 also includes a first left-right moving assembly 314, which includes a first left-right moving cylinder 3141 and a first left-right transverse slide rail 3142. The first left-right transverse slide rail 3142 is arranged on the lifting plate 3112, the bottom of the push plate 3113 cooperates with the first left-right transverse slide rail 3142, the cylinder body of the first left-right moving cylinder 3141 is fixed on the lifting plate 3112, and the piston rod is connected to the push plate 3113. Therefore, through the first left-right transverse slide rail 3142, the push plate 3113 can be pushed along the first left-right transverse slide rail 3142 by the first left-right moving cylinder 3141.

[0046] Specifically, when there is no stator wire frame on the push plate 3113, the piston rod of the first forward and backward moving cylinder 313 extends, pushing the first mounting frame 3111 forward, thereby driving the push plate 3113 to move forward and move to the bottom of the insertion rod 61 of the first feeding rack 6; then, the piston rod of the first lifting cylinder 3121 extends, pushing the push plate 3113 to move upward, clamping the stator wire frame on the insertion rod 61 on the push plate 3113. Then, the piston rod of the first forward and backward moving cylinder 313 pulls back, driving the push plate 3113 to move toward the first rotating shaft 342, until the stator wire frame is inserted into the first rotating shaft 342; the first lifting cylinder 3121 pulls back, pulling the push plate 3113 to move downward. Similarly, when the winding of the stator bobbin on the first rotating shaft 342 is completed, the push plate 3113 is pushed to the bottom of the first rotating shaft 342 by the first forward and backward moving cylinder 313, and then the push plate 3113 is pushed upward by the first lifting cylinder 3121, so that the stator bobbin after winding can fall into the push plate 3113; then, the first forward and backward moving cylinder 313 pushes the push plate 3113 forward, so that the processed stator bobbin on the push plate 3113 is inserted into the insertion rod 61.

[0047] 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 first rotating shaft 342 is being wound, the stator bobbin to be processed is pre-inserted on the insertion rod 61 of the first feeding rack 6; and when the stator bobbin on the first rotating shaft 342 is unloaded, the first left-right moving cylinder 3141 drives the push plate 3113 to move to one side, and after the push plate 3113 moves, the stator bobbin arranged at intervals on the insertion rod 61 can be placed on the push plate 3113, and then the first rotating shaft is loaded. In this way, the loading and unloading time is greatly saved, thereby improving the winding efficiency of the winding device.

[0048] The push plate 3113 is provided with a plurality of material slots 3114, which are square in shape, and the width of the openings 3115 at the front and rear ends of the material slots 3114 is smaller than the width of the middle of the material slots 3114. The number of the material slots 3114 is consistent with the number of the insertion rods 61, so that when loading, the stator bobbins to be wound on the insertion rods 61 are spaced apart on the material slots 3114; when the stator bobbins on the first rotating shaft 342 are wound, the material push plate 3113 is moved to the left or right side, so that the processed stator bobbins can be unloaded to the dislocated material slots 3114, so that the wound and unwound stator bobbins are spaced apart on the push rods.

[0049] By providing a material trough 3114, and the width of the openings 3115 at both ends is smaller than the width of the middle of the material trough 3114, when the pushing plate 3113 is pushed upward, the stator wire frame on the insertion rod 61 or the first rotating shaft 342 can be inserted into the material trough 3114, and then the stator wire frame can be separated from the insertion rod 61 or the first rotating shaft 342 by moving the pushing plate 3113 backward or forward, thereby realizing automatic loading and unloading of the stator wire frame.

[0050] The wire pulling device 33 includes a rotating frame 331, a rotating motor 332, a chuck 333, a bottom plate 334, a second mounting frame 335, a second front-rear moving assembly 336 and a second left-right moving assembly 337. There are multiple chucks 333, all of which are arranged on the rotating frame 331. The rotating frame 331 is arranged on the frame 1. The rotating motor 332 is arranged on the frame 1. The rotating frame 331 is connected to the output shaft of the rotating motor 332. The chuck 333 corresponds to the winding device 32. The second mounting frame 335 is arranged on the bottom plate 334. The rotating frame 331 is arranged on the second mounting frame 335. The second front-rear moving assembly 336 and the second left-right moving assembly 337 are arranged on the bottom plate 334. The rear moving component 336 includes a second front-to-rear moving cylinder 3361, which is arranged on the frame 1, and the piston rod is connected to the base plate 334. The base plate 334 is provided with a second left-right transverse slide rail 3341, and the bottom of the second mounting frame 335 is arranged on the second left-right transverse slide rail 3341. The second left-right moving component 337 includes a second left-right moving cylinder 3371, and the cylinder body of the second left-right moving cylinder 3371 is arranged on the base plate 334, and the piston rod is connected to the second mounting frame 335. The shell of the rotating motor 332 is installed on the second mounting frame 335.

[0051] The chuck 333 can be a pneumatic finger cylinder, which is convenient for clamping and loosening the enameled wire. The rotating frame 331 can be driven to rotate by rotating the motor 332, so that the chuck on the rotating frame 331 rotates with the rotating frame 331. The chuck 333 corresponds to the first rotating shaft 342 one by one, so that each stator wire frame can be wound by the chuck 333 to break the wound enameled wire.

[0052] 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 first rotating shaft 342 is loaded, the piston rod of the second forward and backward moving cylinder 3361 extends, driving the bottom plate 334 to move forward, thereby driving the second mounting frame 335 and the rotating frame 331 to move forward, and the chuck 333 moves forward together. When the chuck moves to the front side of the stator bobbin, the rotating motor 332 drives the rotating motor 332 and the chuck 333 to rotate together, so that the chuck 333 is in a vertical state. At this time, one end of the enameled wire pulled out of the winding device 32 is clamped by the chuck 333; under the clamping action of the chuck 333, the enameled wire is pulled by the winding device 32, 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. Then, the clamp 333 is released, the rotary motor 332 drives the clamp 333 to rotate, the winding device 32 starts to wind on the bobbin of the stator bobbin, and the clamp 333 rotates downward to avoid interfering with the winding of the enameled wire on the stator bobbin.

[0053] 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 32 is winding the pins at the rear end of the stator bobbin, the rotating motor 332 drives the clamp 333 to rotate to a vertical state, and pulls back through the second forward and backward moving cylinder 3361, driving the rotating frame 331 to move backward and move to the rear side of the stator bobbin on the first rotating shaft 342 to avoid interfering with the winding of the winding device. When the stator bobbin winding is completed, the second forward and backward moving cylinder 3361 extends forward, pushes the clamp 333 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 32; then the piston rod of the second left and right moving cylinder 3371 extends, pushes the second mounting frame 335 and the clamp 333 to move to the side away from the corresponding stator bobbin, so that the enameled wire is broken, and the stator bobbin winding is completed. Finally, the feeding device 31 is used to unload the material, 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.

[0054] The winding device 32 includes a winding frame 321, an adjusting frame 322 and a telescopic cylinder 323. The winding frame 321 is provided with a wire hole 3211, and the wire hole corresponds to the first rotating shaft 342. The winding frame 321 is located above the first rotating shaft 342, and the adjusting frame 322 is located above the winding frame 321. The cylinder body of the telescopic cylinder 323 is arranged on the winding frame 321, and the piston rod is connected to the adjusting frame 322. The adjusting frame 322 is provided with a guide wheel, and the guide wheel corresponds to the wire hole. The wire hole can facilitate the pulling out of the enameled wire. At the same time, a pull head can be installed below the wire hole to facilitate the tightening of the enameled wire. After passing through the guide wheel, the enameled wire is pulled to the wire hole on the winding frame 321. 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.

[0055] 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 323 is pulled down, so that the distance between the guide wheel on the adjustment frame 322 and the wire hole on the winding frame 321 is shortened, thereby making the enameled wire in a relaxed state, which is convenient for the winding device 32 to wind on the pin. After the winding on the pin is completed, the piston rod of the telescopic cylinder 323 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 slot of the stator bobbin.

[0056] The winding device 32 further includes a third front-to-back moving assembly 324, a third left-to-right moving assembly 325 and a lifting assembly 326. The third front-to-back moving assembly 324 includes a front-to-back longitudinal slide rail 3241, a front-to-back moving motor 3242 and a front-to-back moving plate 3243. The third left-to-right moving assembly 325 includes a third left-to-right transverse slide rail 3251, a left-to-right moving motor and a left-to-right moving plate 3252. The lifting assembly 326 includes a vertical slide rail 3261 and a lifting motor 3262. The front-to-back longitudinal slide rail 3241 is arranged on the frame 1. The front-to-back moving plate 3243 cooperates with the front and rear longitudinal slide rails 3241, the front and rear moving motor 3242 is connected to the front and rear moving plates 3243, the third left and right transverse slide rails 3251 are arranged on the front and rear moving plates 3243, the left and right moving plates 3252 are arranged on the third left and right transverse slide rails 3251, the left and right moving motor is connected to the left and right moving plates 3252, the vertical slide rail 3261 is arranged at the front end of the left and right moving plates 3252, one side of the winding frame 321 cooperates with the vertical slide rail 3261, and the output shaft of the lifting motor 3262 is connected to the winding frame 321.

[0057] Specifically, the output shaft of the front-to-back moving motor 3242 is connected to the front-to-back moving plate 3243 through the first screw rod, and the front-to-back moving plate 3243 is threadedly matched with the first screw rod, so that the front-to-back moving motor 3242 can accurately control the front-to-back moving distance of the front-to-back moving plate 3243. Similarly, the output shaft of the left-to-right moving motor is connected to the left-to-right moving plate 3252 through the second screw rod, so as to accurately control the left-to-right moving distance of the left-to-right moving plate 3252; the lifting motor 3262 is connected to the winding frame 321 through the third screw rod, so as to accurately control the up-and-down moving distance of the winding frame 321.

[0058] When the front-back moving motor 3242 is working, the front-back moving plate 3243 can be driven to move forward or backward along the front-back longitudinal slide rails 3241, and the third left-right transverse slide rails 3251 and the left-right moving plate 3252 can be driven to move forward or backward through the front-back moving plate 3243, and the vertical slide rail 3261 and the winding frame 321 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 321 can be realized through the front-back moving motor 3242. When the left-right moving motor is working, the left-right moving plate 3252 can be driven to move left-right along the third left-right transverse slide rails 3251, and the vertical slide rail 3261 and the winding frame 321 can be driven to move left-right through the left-right moving plate 3252. When the lifting motor 3262 is working, the winding frame 321 can be driven to move up and down along the vertical slide rail 3261.

[0059] The specific winding process of the winding device 32 is as follows:

[0060] When the clamp 333 is located at one side of the front end of the stator bobbin on the first rotating shaft 342 and clamps the enameled wire, the winding frame 321 is also located at one side of the front end of the stator bobbin. The left and right moving motor drives the winding frame 321 to move toward 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 322 moves downward. After the winding frame 321 moves into place, the front and back moving motor 3242 and the left and right moving motor are linked to drive the winding frame 321 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 333 releases the enameled wire and rotates downward; the rotating motor drives the first rotating shaft 342 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 3242 drives the winding frame 321 to move forward and backward, so that the enameled wire is wound on the entire wire slot.

[0061] After the enameled wire is wound back and forth on the wire slot of the stator wire rack for multiple turns, the forward and backward moving motor 3242 moves to the side of the pin at the front end of the stator wire rack, and then the left and right moving motor pushes the winding frame 321 to move to the side of the pin on the right. After the winding frame 321 moves to the side of another pin at the front end of the stator wire rack, the forward and backward moving motor 3242 and the left and right moving motor are linked to drive the winding frame 321 to achieve forward and backward and left and right movement, 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 rack is completed, after the winding frame has wound the corresponding number of turns on the wire slot, the forward and backward moving motor 3242 drives the winding frame 321 to move to the side of the pin at the rear end of the stator wire rack 31, and the same operation is performed to realize the winding of the pin at the rear end of the stator wire rack. Among them, when the winding frame is winding the pin, the rotating motor 341 stops rotating, that is, the first rotating shaft 342 stops rotating, which facilitates the winding of the enameled wire on the pin.

[0062] When the winding is completed on the wire slots and pin terminals of the stator bobbin, the left-right moving motor pushes the bobbin 321 to move toward the side of the clamp 333, and the clamp 333 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 3371, so that the enameled wire is pulled off by the clamp 333, so that the enameled wire on the bobbin is separated from the stator bobbin, the winding is completed, and the rotating motor 341 stops rotating. Then, the material is unloaded through the push plate, and the unwound stator bobbin is loaded, and the winding is repeated.

[0063] In actual use, a stator automatic assembly line of the present invention also includes a flip cylinder 9, a winding frame 321 includes a frame 3211 and a winding plate 3212, the frame 3211 is arranged on a vertical slide rail 3261, two ends of the winding plate 3212 are arranged on the frame 3211, and are rotatably connected to the frame 3211, the wire hole and the pull head are both arranged on the winding plate 3212, and the winding plate 3212 can be driven by the frame 3211 to move forward and backward, left and right, and up and down together; there are two flip cylinders 9, which are respectively arranged on both sides of the frame 3211, and the flip cylinder 9 is tilted on the frame 3211, and the piston rod of the flip cylinder 9 is connected to the two ends of the winding plate 3212. The winding plate 3212 can be driven to rotate by the extension and contraction of the piston rod of the flip cylinder 9. As described above, the first rotating shaft 342 is in a horizontal state. When the stator wire rack is horizontally inserted into the first rotating shaft 342, 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.

[0064] like Figure 1 to Figure 4As shown, in actual use, after the stator bobbin after winding on the winding mechanism 3 is unloaded to the first feeding rack 6, the first feeding rack 6 moves along the guide rail 11 to the side of the conveying mechanism 2. The stator automatic assembly line of the present invention also includes a discharge rack 20, which is arranged on the frame 1, and the discharge rack 20 is located between the conveying mechanism 2 and the winding mechanism 3. The first feeding rack 6 moves to the discharge rack 20, and the wound stator bobbin is taken out from the insertion rod 61 of the first feeding rack 6 through the discharge rack 20. A conveyor belt is provided on one side of the discharge rack 20, and the conveyor belt is located below the first feeding rack 6. When the discharge rack 20 pushes the stator from the first feeding rack 6, it falls directly onto the conveyor belt, and the conveyor belt drives the stator to move to the side of the rubber coating mechanism 4.

[0065] Among them, the unloading rack 20 is provided with a front and rear telescopic cylinder 201 and a top and bottom telescopic cylinder 202, the top and bottom telescopic cylinder 202 is connected with the piston rod of the top and bottom telescopic cylinder 201, and the cylinder body of the top and bottom telescopic cylinder 201 is fixed on the frame 1; the piston rod of the top and bottom telescopic cylinder 202 is provided with a socket 203, and there are two sockets 203, which correspond to the stator wire racks that are arranged at intervals and have been wound. When the stator to be unloaded on the first feeding rack 6 moves to the unloading rack 20, the front and rear telescopic cylinder 201 pushes the top and bottom telescopic cylinder 202 to move toward the side of the first feeding rack 6. After moving into place, the top and bottom telescopic cylinder 202 drives the socket 203 to move downward, inserts the socket on the stator wire rack, and pulls the top and bottom telescopic cylinder 202 in the direction, so that the socket 203 pulls the stator wire rack out of the first feeding rack 6.

[0066] In order to facilitate the operator to assemble the fuse on the stator bobbin after winding, an operation table is provided between the winding mechanism 3 and the rubber coating mechanism 4. The stator bobbin after unloading from the unloading rack is transported to the operation table via a conveyor belt. After the operator assembles the fuse on the stator, the stator is placed on the second feeding rack 7. The structure of the second feeding rack 7 is the same as that of the first feeding rack 6. Through the second feeding rack 7, the stator is transported to the rubber coating mechanism 4 for rubber coating.

[0067] like Figure 1 , Fig.11 and Fig.12As shown, the rubber coating mechanism 4 includes a tape rack 41, a turntable 42, a cutter 43, a first rubber coating motor, a second rubber coating motor, a turntable motor and a rubber coating clamping assembly 44. The turntable motor is arranged on the frame 1, and the turntable 42 is connected to the output shaft of the turntable motor. The bodies of the first rubber coating motor and the second rubber coating motor are both arranged on the turntable 42. The tape rack 41 is arranged on one side of the turntable 42. The output shaft of the first rubber coating motor is provided with a second rotating shaft 45, and the output shaft of the second rubber coating motor is provided with a third rotating shaft 46. One side of the rubber coating clamping assembly 44 corresponds to the second rotating shaft 45 and the third rotating shaft 46, and the other side corresponds to the second feeding rack 7. The cutter 43 is located on one side of the second rotating shaft 45 and the third rotating shaft 46.

[0068] In order to facilitate the movement of the stator on the second feeding rack 7 to the rubber coating mechanism 4 for rubber coating treatment, the rubber coating clamping assembly 44 includes a moving motor 304, a transmission screw 301, a rubber coating lifting cylinder 302 and a rubber coating clamping cylinder 303, wherein the moving motor 304 is fixed on the frame, the transmission screw 301 is connected to the output shaft of the moving motor, the cylinder body of the rubber coating lifting cylinder 302 is connected to the transmission screw 301, and the rubber coating clamping cylinder 303 is connected to the piston rod of the rubber coating lifting cylinder 302; wherein the rubber coating clamping cylinder 303 is a pneumatic finger cylinder.

[0069] When the second feeding rack 7 transports the stator to the rubber coating mechanism 4, the mobile motor drives the rubber coating lifting cylinder 302 and the rubber coating clamping cylinder 303 to move toward the side of the second feeding rack 7, and the stator on the second feeding rack 7 is clamped by the rubber coating clamping cylinder 303 and moved to the second rotating shaft 45 or the third rotating shaft 46 located below; the turntable 42 is driven by the turntable motor to rotate, so that the other rotating shaft can be rotated to the bottom, so as to facilitate the stator to be mounted on the other rotating shaft.

[0070] When the rubber coating mechanism 4 is rubber coating, the tape on the tape rack 41 is pulled out, and one end of the tape is fixed on the stator on the second rotating shaft 45 or the third rotating shaft 46 above, and the rubber coating is completed on the upper stator; then the turntable 42 is driven by the turntable motor to rotate 180°, so that the upper and lower positions of the stator change. When the stator is turned upside down, the tape is pulled by one stator and pressed against the other stator. At this time, the stator that has been rubber coated is located at the bottom. The tape connecting the two stators is cut by the cutter 43, and the stator that has been rubber coated at the bottom is moved to the second feeding rack 7 via the rubber coating moving component 30; at the same time, the corresponding rubber coating motor located at the top drives the corresponding rotating shaft to rotate, so that the tape is coated on the upper stator, and the rubber coating is completed after the required number of turns are wound. The rubber coating moving component 30 repeatedly takes and places the stator, and the rubber coating mechanism 4 repeats the action to rubberize the stator, ensuring the uniformity and stability of the quality of the stator rubber coating.

[0071] When the stators on the second feeding rack 7 are all coated with rubber, the second feeding rack 7 transports the stators to the tinning mechanism 5 .

[0072] like Figure 1 , Fig.12 , Fig.13 and Fig.15 As shown, the tinning mechanism 5 includes a tinning frame 51, a tinning forward and backward moving assembly 52, a tinning up and down moving assembly 53, a rotating assembly 54, a rosin water tank 55, a tin tank 56, a pressing platform 57 and a testing platform 58. The tinning frame 51 corresponds to the second feeding frame 7. The tinning forward and backward moving assembly 52 is arranged on the frame 1. The tinning frame 51 is connected to the tinning forward and backward moving assembly 52. ​​The tinning frame 51 is provided with a stator mounting frame 511. The tinning up and down moving assembly 53 is arranged on the tinning frame 51 and connected to the stator mounting frame 511. The rotating assembly 54 is connected to the stator mounting frame 511. The rosin water tank 55, the tin tank 56, the pressing platform 57 and the testing platform 58 are all located below the tinning frame 51 and are arranged in sequence from front to back. Among them, the pressing platform 57 is a horizontal plate.

[0073] There is rosin water in the rosin water tank 55, and there is high-temperature tin liquid in the tin tank 56. The detection table 58 detects the conductivity of the stator, and the detection principle is the same as the existing stator detection principle.

[0074] There are multiple pneumatic finger cylinders distributed on the stator mounting frame 511. When the tinning forward and backward moving assembly 52 drives the tinning frame 51 to move forward, it moves to the second feeding frame 7, and the pneumatic finger cylinder on the stator mounting frame 511 clamps the stator on the second feeding frame 7. Then, the tinning forward and backward moving assembly 52 drives the tinning frame 51 to move toward the side of the rosin water tank 55. When the tinning frame 51 moves to the rosin water tank 55, the tinning up and down moving assembly 53 pushes the tinning frame 51 to move downward, so that the pin terminals on one side of the stator are immersed in the rosin water in the rosin water tank 55; then, the tinning up and down moving assembly 53 drives the tinning frame 51 to move upward, and the rotating assembly 54 drives the stator mounting frame 511 to rotate, so that the pin terminals on the other side of the stator move downward and are immersed in the rosin water, realizing the first rosin water immersion.

[0075] When the pins on both sides of the stator are soaked in rosin water, the tinning forward and backward moving component 52 drives the stator to move above the tin tank 56. The stator pins are soaked in tin on the tin tank 56 in the same way as the rosin water, ensuring that the pins on both sides of the stator can be soaked in tin and the first soldering is achieved.

[0076] In order to ensure the uniformity of the stator solder and the solder quality of the product, after the first soldering is completed, a second rosin water soaking is carried out in the same way as the first soaking; after the second soaking in rosin water is completed, a second soldering is carried out in the same way as the first soldering.

[0077] In order to facilitate the tinning forward and backward moving component 52, the tinning up and down moving component 53 and the rotating component 54 to control the forward and backward, up and down and rotating movements of the stator mounting frame, the tinning forward and backward moving component 52 includes a tinning motor 521, a transmission belt 522 and a tinning front and rear guide rail 523. The tinning motor 521 is arranged on the frame 1, and the transmission belt 522 is connected to the output shaft of the tinning motor 521. The tinning frame 51 is installed on a moving seat, and the moving seat is fixed on the transmission belt 522. The tinning frame 51 can be driven to move forward and backward by the rotation of the tinning motor 521. The tinning up and down moving component 53 includes a tinning lifting cylinder 531, the cylinder body of the tinning lifting cylinder 531 is fixed on the moving seat, and the piston rod is connected to the tinning frame 51, which can drive the tinning frame 51 to move up and down, thereby driving the stator mounting frame 511 to move up and down. The rotating assembly 54 includes a tin-immersion rotating motor 541 . A synchronous wheel is provided on the output shaft of the tin-immersion rotating motor 541 . The synchronous wheel is connected to the stator mounting frame 511 . The stator mounting frame 511 is driven to rotate by the rotation of the tin-immersion rotating motor.

[0078] After the stator soldering is completed, the stator is moved to the pressing platform 57 by the combined action of the tinning forward and backward moving assembly 52, the tinning up and down moving assembly 53 and the rotating assembly 54. The pins can be pressed and aligned by pressing the stator down on the pressing platform 57. Finally, it is transported to the testing station 58 for conductivity testing to complete the assembly.

[0079] Therefore, the stator automatic assembly line of the present invention realizes the automatic conveying, winding, encapsulation and soldering process of the stator without manual operation, which greatly saves manpower, ensures the stability of the stator assembly quality, and improves the yield rate.

[0080] 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.
