Description

Technical Field

[0001] This application relates to the field of motor stator processing equipment technology, and more specifically, to a new energy vehicle motor stator electromagnetic coil forming equipment. Background Technology

[0002] The precision requirements for stator coil forming in new energy vehicle motors are far higher than those in traditional industrial motors. The winding and forming quality of the stator coils directly affects the motor's slot fill factor, insulation performance, and output performance. In recent years, rectangular enameled copper flat wire has been used to replace traditional round enameled wire. This is because using enameled copper flat wire in the motor stator can improve the slot fill factor, and the contact heat exchange area is much larger than that of round wire, resulting in better heat dissipation performance. The processing, winding, and conveying of enameled copper flat wire outside the motor stator mainly uses a rigid pressure roller extrusion conveying method. Since the enamel film thickness is thinnest at the edge of the flat wire, traditional rigid pressure roller conveying during the production and processing of the external electromagnetic coils of the stator can easily cause damage, paint peeling, and cracks in the enameled copper flat wire, directly leading to inter-turn short circuits, poor withstand voltage, and a decrease in finished product yield.

[0024] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this application, not all of them. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0025] Therefore, the following detailed description of the embodiments of this application provided in the accompanying drawings is not intended to limit the scope of the claimed application, but merely to illustrate selected embodiments of the application. All other embodiments obtained by those skilled in the art based on the embodiments in this application without inventive effort are within the scope of protection of this application.

[0026] The following description, with reference to the accompanying drawings, describes a new energy vehicle motor stator electromagnetic coil forming device according to an embodiment of this application.

[0027] Please see Figures 1-7 According to an embodiment of this application, a new energy vehicle motor stator electromagnetic coil forming equipment includes: a frame 1, a stator feeding mechanism 2, a coil winding mechanism 3, and a flat wire feeding mechanism 4.

[0028] The stator feeding mechanism 2 and the coil winding mechanism 3 are both mounted above the frame 1 to cooperate in winding flat copper wire around the stator coil. The flat wire feeding mechanism 4 includes a base frame 41, a side shell 42, a feeding belt drive assembly 43, an upper flexible roller 44, and a lower flexible roller 45. The upper flexible roller 44 and the lower flexible roller 45 are made of flexible rubber. The base frame 41 is bolted to the bottom of the side shell 42 and connected to the frame 1. Both ends of the side shell 42 are provided with wire through holes 421. The upper flexible roller 44 and the lower flexible roller 45 are located inside the side shell 42. The upper flexible roller 44 and the lower flexible roller 45 are each provided with an air guide layer 47. The outer ring of the upper flexible roller 44 and the lower flexible roller 45 is provided with multiple adsorption air holes 48 that communicate with the air guide layer 47 at equal intervals. The sides of the lower flexible roller 45 and the upper flexible roller 44 are provided with air guide pipes 46 that communicate with the air guide layer 47. The air guide pipe 46 is connected to an external negative pressure pneumatic system (not shown). The feed belt drive assembly 43 is installed on the outside of the side shell 42 and drives the upper flexible roller 44 and the lower flexible roller 45 to adsorb and feed the flat wire to the coil winding mechanism 3 in the same direction.

[0029] The working principle of this new energy vehicle motor stator electromagnetic coil forming equipment is as follows: The stator is installed on the stator feeding mechanism 2, and the enameled copper flat wire is fed through the flat wire feeding mechanism 4 to the coil winding mechanism 3. The flat wire feeding mechanism 2 cooperates with the stator feeding mechanism 2 to complete the forming process of the stator's peripheral electromagnetic coil. The flat wire feeding mechanism 4 feeds the wire at a distance. The feeding belt drive assembly 43 drives the upper flexible roller 44 inside the side shell 42 to move towards the coil winding mechanism 3. The external air pressure system maintains the air guide layer 47 inside the upper flexible roller 44 and lower flexible roller 45 under rated negative pressure through the air guide pipe 46. The multiple adsorption air holes 48 on the opposite outer surfaces of the upper flexible roller 44 and lower flexible roller 45 can adsorb the enameled copper flat wire between them, and cooperate with the feeding belt drive assembly 43 to complete the wire conveying. The flat wire feeding mechanism 4 uses an upper flexible roller 44 and a lower flexible roller 45 with adsorption holes 48 arranged on them to adsorb and convey the enameled copper flat wire. The clamping force is a flexible adsorption force, and the feeding process is free of rigid extrusion, which completely eliminates the problems of pressure damage, wear and cracking of the flat wire paint layer.

[0030] In a specific configuration, the feed belt drive assembly 43 includes a motor V 431, a drive roller 432, a driving roller 433, a driven roller 434, and a passive roller 435. The drive roller 432, driving roller 433, driven roller 434, and passive roller 435 are rotatably mounted with the side shell 42. The lower flexible roller 45 is disposed outside the drive roller 432 and driving roller 433, and the upper flexible roller 44 is disposed outside the driven roller 434 and passive roller 435. The driving roller 433 and driven roller 434 are connected and engaged by a gear set 436.

[0031] Motor V431 drives drive roller 432 to rotate, which in turn drives lower flexible roller 45 to rotate through the cooperation of drive roller 433; through the cooperation of gear set 436, driven roller 434 and driven roller 435 drive upper flexible roller 44 and lower flexible roller 45 to move in the same direction relative to each other.

[0032] Furthermore, the air guide pipe 46 includes a flexible conduit 462, and one side of the upper flexible roller 44 and the lower flexible roller 45 is provided with an end interface 461 that communicates with the air guide layer 47. One end of the flexible conduit 462 is connected to the end interface 461; the other end of the flexible conduit 462 is connected to the negative pressure pneumatic system.

[0033] In the above specific embodiment, the frame 1 includes a base 11 and a leg frame 12. The leg frame 12 is fixed to the bottom of the base 11. The bottom of the base 11 is respectively equipped with a moving wheel 13 and an adjustable leg support 14. The moving wheel 13 facilitates the overall transfer of the molding equipment, while the adjustable leg support 14 is used to stably support the molding equipment.

[0034] In the above specific embodiment, the stator feeding mechanism 2 includes a platform 21, stator frames 22, a transmission unit 23, a rotation drive component 24, a cylinder 25, and a motor II 26. The platform 21 is rotatably mounted above the base 11. The motor II 26 is mounted on the bottom of the base 11 to drive the platform 21 to rotate. Four stator frames 22 are rotatably mounted above the platform 21. The transmission unit 23 connects to the bottom of two stator frames 22 as a group. The rotation drive component 24 drives two stator frames 22 as a group to rotate synchronously. The cylinder 25 is mounted inside the leg frame 12 to drive the rotation drive component 24 to adjust its height. The rotating drive 24 drives one stator frame 22 to rotate. Through the cooperation of the transmission part 23, the two stator frames 22 are driven to rotate synchronously, so that the two stators can be wound synchronously. The other two stator frames 22 are used to install motor stators for preparation. After the motor stators on the two stator frames 22 have completed winding, the cylinder 25 drives the rotating drive 24 to move down, and the motor II 26 drives the platform 21 to rotate, which drives the stator frames 22 above the platform 21 to rotate and exchange positions. After the stator frames 22 have been exchanged, the cylinder 25 drives the rotating drive 24 to move up, so that the exchanged stator frames 22 can continue to rotate.

[0035] Furthermore, the rotation drive component 24 includes a motor I 241 and a cylinder base 242. The motor I 241 is installed and docked with the actuator end of the cylinder 25. The bottom end of the cylinder base 242 is connected to the output shaft end of the motor I 241, and the top end of the cylinder base 242 is inserted and positioned with the bottom end of the stator frame 22. The output shaft end of the motor I 241 drives the cylinder base 242 to rotate, and the top end of the cylinder base 242 can be inserted and engaged with the bottom end of the stator frame 22 to drive the stator frame 22 to rotate.

[0036] Specifically, the coil winding mechanism 3 includes an outer housing 31, a feeding assembly 32, and a rotating winding assembly 33. The feeding assembly 32 is mounted above the base 11 to drive the outer housing 31 to move and adjust. The rotating winding assembly 33 is installed in conjunction with the outer housing 31. The rotating winding assembly 33 includes a guide clamp 331, a drive shaft 332, and a rotation drive unit 333. The drive shaft 332 is rotatably mounted to the outer housing 31, and the drive shaft 332 has a hollow structure inside to allow flat wire to pass through. The guide clamp 331 is mounted at one end of the drive shaft 332, and the rotation drive unit 333 is installed in conjunction with the outer housing 31 to drive the drive shaft 332 to rotate. The rotation drive unit 333 includes a motor IV 3331, a main pulley 3332 and a driven pulley 3333. The main pulley 3332 is mounted on the output shaft end of the motor IV 3331, and the driven pulley 3333 is mounted on one end of the transmission shaft 332 and the principle guide wire clamp 331. A transmission belt is provided between the main pulley 3332 and the driven pulley 3333, and a pressure pulley 3334 is provided on the outside of the transmission belt.

[0037] The output shaft of the motor IV 3331 in the rotation drive unit 333 drives the main pulley 3332 to rotate. Through the cooperation of the transmission belt and the driven pulley 3333, the transmission shaft 332 and the winding clamp 331 are rotated. The feed assembly 32 drives the outer housing 31 to move and adjust, that is, drives the winding clamp 331 to move and adjust. The transmission shaft 332 and the winding clamp 331 are both set in two sets to realize the synchronous winding operation of the two sets of motor stators.

[0038] Furthermore, an outer protective cover 35 is installed on the outside of the rotary drive unit 333, and a guide rail 34 is provided above the base 11 to slide in cooperation with the outer housing 31. The feed assembly 32 includes a motor III 321, a shaft seat 322, and a lead screw 323. The lead screw 323 is located between the two motors III 321, and the motors III 321 are mounted above the base 11 to drive the lead screw 323 to rotate. The output shaft end of the motor III 321 in the feed assembly 32 is connected to the lead screw 323 through a coupling. The rotating lead screw 323 is screwed through to the bottom of the outer housing 31 to realize the axial feed adjustment of the outer housing 31 along the lead screw 323.

[0039] If the conventional wire structure is used before feeding the flat wire feeding mechanism 4 of the above-mentioned new energy vehicle motor stator electromagnetic coil forming equipment, that is, when the wire roller is feeding the wire, excessive pressure can easily cause the enamel layer on the surface of the enameled copper flat wire to fall off, while insufficient pressure can easily cause the wire feeding to be skewed, resulting in poor wire feeding effect.

[0040] Please see Figure 1 , Figure 5 , Figure 8 , Figure 9 and Figure 10The new energy vehicle motor stator electromagnetic coil forming equipment also includes a flat wire conductor mechanism 5 and a pressing and guiding assembly 6. The flat wire conductor mechanism 5 includes a support arm 51, a mounting plate 52, a box 53 with open top and bottom, and a connecting pipe 54. A square flexible ring band 49 is fixedly installed at the top and bottom of the side shell 42, and an air inlet 422 connected to the inside of the flexible ring band 49 is provided at the top and bottom of the side shell 42. One end of the connecting pipe 54 is connected to the air inlet 422. The flexible ring band 49 is in contact with the outer ring of the upper flexible roller 44 and the lower flexible roller 45. The support arm 51 is fixedly connected to the frame 1 and the mounting plate 52, and the box 53 is fixed inside the mounting plate 52. The box 53 contains a partition 55 and a flexible plate 57. The flexible plate 57 is located below the partition 55. The flexible plate 57 and the partition 55 together with the inner wall of the box 53 form a flow guide cavity 58. Multiple air guide cylinders 56 are arranged below the partition 55 and are connected to each other. The other end of the connecting pipe 54 passes through the side wall of the box 53 and is connected to the flow guide cavity 58 above the flexible plate 57. The number of pressure guide components 6 corresponds to the number of air guide cylinders 56. The pressure guide component 6 includes a base 61, a shaft 62, a rubber wheel 63, and a rubber sleeve 64. The rubber wheel 63 is rotatably mounted below the base 61 through the shaft 62. The rubber sleeve 64 is installed at the end of the shaft 62 and is fixedly connected to the box 53. A column block 65 that passes through the flexible plate 57 is fixed on the top of the base 61. A stamping plate 66 is provided on the top of the column block 65.

[0041] The adsorption pores 48 at the top of the upper flexible roller 44 and the bottom of the lower flexible roller 45 create a negative pressure inside the flexible belt 49. The airflow passes through the top of the box 53, through the air guide cylinder 56, into the guide cavity 58, and then through the connecting pipe 54 into the flexible belt 49. When external air flows in from the air guide cylinder 56, it will impact the stamping plate 66 located directly below the air guide cylinder 56. The stamping plate 66 will move under the elastic action of the flexible plate 57, so that the rubber wheels 63 in the two sets of pressure guiding components 6 will move towards each other to press and guide the flat wire before feeding, avoiding excessive compression of the flat wire while stabilizing the flat wire to the flat wire feeding mechanism 4.

[0042] Each of the multiple sets of pressure-holding guide components 6 has an individual air guide cylinder 56 above its pressure plate 66. The airflow velocity in the air guide cylinder 56 near the port of the connecting pipe 54 is the fastest, meaning that the pressure plate 66 in the pressure-holding guide component 6 closest to the port of the connecting pipe 54 experiences the greatest airflow impact force. As the distance from the port of the connecting pipe 54 increases, the pressure on the pressure plate 66 in the pressure-holding guide component 6 gradually decreases, meaning the pressure between the rubber wheels 63 also gradually decreases. The rubber wheel 63 in the outermost pressure-holding guide component 6 furthest from the end of the connecting pipe 54 is in initial contact with the flat wire surface, resulting in even lower pressure and providing initial guidance. As the flat wire is guided deeper, the rubber wheels 63 in the pressure-holding guide component 6 gradually increase their pressure and guidance force as they approach the port of the connecting pipe 54. This not only achieves high-quality and safe guidance of the flat wire but also provides a good straightening effect.

[0043] In the specific configuration, a bearing I 69 is installed at the end of the shaft 62, embedded inside the rubber sleeve 64. The outer side of the rubber sleeve 64 has a groove 68 that mates with the mounting slot on the side of the housing 53. An annular cavity 67 is provided inside the rubber sleeve 64. When the flat wire passes between the opposing rubber wheels 63, the rubber sleeve 64 at the end of the mounting plate 52 provides good elasticity to protect the flat wire being held in place. The groove 68 enhances the stability of the rubber sleeve 64 during installation, while the annular cavity 67 enhances the elasticity of the rubber sleeve 64, further protecting the flat wire held by the rubber wheels 63.

[0044] When air enters the top of the box 53 in the flat wire conductor mechanism 5 of the above-mentioned new energy vehicle motor stator electromagnetic coil forming equipment, debris in the air can easily enter the air guide cylinder 56 and block the air guide cylinder 56 and the connecting pipe 54.

[0045] Please see Figure 9 The new energy vehicle motor stator electromagnetic coil forming equipment also includes a self-cleaning filter assembly 7, which includes a rotating shaft 71, blades 72, bearings II 73, and a filter screen 74. The filter screen 74 is located above the partition 55 and fixed to the inner wall of the box 53. Two bearings II 73 are respectively located above the filter screen 74 and installed at both ends of the box 53. The rotating shaft 71 is rotatably positioned between the two bearings II 73. Five blades 72 are arranged in a ring array outside the rotating shaft 71. The opening at the top of the box 53 is an air intake groove 59 structure biased to one side.

[0046] External air enters the rubber wheel 63 through the air inlet slot 59, is filtered by the filter screen 74, and then passes through the baffle 55 into the guide cavity 58. The filtering effect of the filter screen 74 makes the gas entering the guide cylinder 56 cleaner, preventing blockage of the guide cylinder 56 and the connecting pipe 54. When external air enters through the air inlet slot 59 and forms an airflow, the incoming airflow first contacts a blade 72 on the side of the rotating shaft 71. Then, the airflow drives the blade 72 on the outside of the rotating shaft 71 to rotate. The rotating blade 72 cleans the impurities remaining on the upper surface of the filter screen 74, preventing the surface of the filter screen 74 from being blocked by impurities and affecting the operation of the entire mechanism of the flat wire conductor mechanism 5, thus playing a good self-cleaning protection role.
