[0002] The rotor is a crucial component of an electric motor, bearing the motor's magnetic field and mechanical forces, and having a vital impact on the motor's performance and efficiency. The rotor core typically employs a laminated structure, composed of multiple thin silicon steel sheets stacked together. Each silicon steel sheet undergoes special treatment to reduce iron losses and hysteresis losses, thereby improving the motor's efficiency.

The height of the shaft clamping drive device 34 can be adjusted by adjusting the position of the mounting base 32 on the support frame 31 according to the size specifications of the rotor 200. In this way, the shaft clamping support device 30 has a certain degree of adjustability to adapt to rotors 200 of different sizes and specifications, thereby improving its applicability.

The flipping device 103, shaft clamping support device 30, and flying fork winding device 104 are arranged side-by-side, and the wire guarding device 105 is disposed between the flipping device 103 and the shaft clamping support device 30. In this embodiment, the frame 101 includes a base plate 1011, and the transfer device 102... 2. The flipping device 103, the clamping shaft support device 30, the flying fork winding device 104, and the wire guarding device 105 are all mounted on the base plate 1011 and supported by the base plate 1011. The number of the flipping device 103, the clamping shaft support device 30, the flying fork winding device 104, and the wire guarding device 105 is two, but not limited to two. Each clamping shaft support device 30 corresponds to one flipping device 103, one flying fork winding device 104, and one wire guarding device 105. The two flipping devices 103, the two clamping shaft support devices 30, the two flying fork winding devices 104, and the two wire guarding devices 105 are respectively arranged on opposite sides of the transfer device 102.
[0032] Please continue reading Figure 1 and Figure 2 The flipping device 103 provided in this embodiment is used to flip the axis of the rotor 200 by 90 degrees so that the axis of the rotor 200 is perpendicular to the substrate 1011. In this embodiment, a feeding assembly 106 is provided on one side of the frame 101 to provide the rotor 200. The rotor 200 is placed on the feeding assembly 106 with its rotating shaft 201 placed in a generally horizontal manner. It is then picked up by a corresponding feeding robot (not shown) and placed on the flipping device 103. The flipping device 103 flips the rotor 200 so that the rotating shaft 201 is perpendicular to the substrate 1011.
[0033] See Figure 1 and Figure 2 The transfer device 102 provided in this embodiment is used to clamp the rotor 200 and drive the rotor 200 to move. In this embodiment, the transfer device 102 includes a transfer bracket 1021 fixed on the frame 101 and two clamping components 1022 for clamping the rotor 200. The two clamping components 1022 are respectively arranged on opposite sides of the transfer bracket 1021 and can reciprocate between the corresponding flipping device 103 and the corresponding clamping shaft support device 30.
[0034] See Figure 1 and Figure 2The flying fork winding device 104 provided in this embodiment is used to wind wire onto each tooth of the rotor 200 on the clamping shaft support device 30. It includes a flying fork head, which can wind the enameled wire (not shown) provided by the wire supply device 107 onto the iron core 202 of the rotor 200.

[0035] See Figures 1 to 5 , Figure 7 The wire protection device 105 provided in this embodiment includes two relatively movable wire protection blocks 1051. After the two wire protection blocks 1051 move towards each other, they form a wire protection space for accommodating the rotor 200. In this embodiment, the wire protection device 105 includes two wire protection blocks 1051 and a wire protection power member 1052 that can drive the two wire protection blocks 1051 to move relative to each other on a plane parallel to the surface of the substrate 1011. The wire protection power member 1052 is, but is not limited to, a cylinder. The inner wall of the wire protection block 1051 is formed with an arc surface that matches the surface shape of the rotor 200 core 202. When the two wire protection blocks 1051 move toward the axial direction of the rotor 200, the wire protection space formed by the two wire protection blocks 1051 can cover most of the non-winding teeth on the rotor 200 core 202, thereby guiding the enameled wire during winding and preventing the enameled wire from colliding with the teeth on the core 202 during winding.
[0036] See Figure 1 and Figure 2 The clamping shaft support device 30 provided in this embodiment is used to support the rotor 200. The rotor 200 is placed on the clamping shaft support device 30 with its axis perpendicular to the base plate 1011. In this embodiment, the clamping shaft support device 30 includes a support frame 31 fixed to the frame 101, an assembly seat 32 adjustablely supported on the support frame 31 in the direction perpendicular to the base plate 1011, and a clamping shaft drive device 34 for clamping the rotor 200 and rotating the rotor 200. The clamping shaft drive device 34 is supported on the assembly seat 32. In this way, the height position of the clamping shaft drive device 34 can be adjusted by adjusting the position of the assembly seat 32 on the support frame 31 according to the size specifications of the rotor 200, thereby adapting to rotors 200 of various sizes.
[0037] See Figures 3 to 5 , Figure 7The support frame 31 provided in this embodiment includes a base plate 311 and side plates 312 mounted on opposite sides of the base plate 311. A height adjustment groove 3121 is provided on the side plate 312, extending in a direction perpendicular to the base plate 1011. A plurality of fixing holes 321 corresponding to the height adjustment groove 3121 are provided on the side wall of the mounting base 32, spaced apart in a direction perpendicular to the base plate 1011. An adjustable locking component 33 is provided on the side plate 312. The inner end of the adjustable locking component 33 is inserted into the fixing hole 321 through the height adjustment groove 3121. The adjustable locking component 33 has a threaded portion (not shown), and a threaded mating portion (not shown) that mates with the threaded portion is provided in the fixing hole 321. In this embodiment, the base plate 311 and the base plate of the frame 101... The base plate 1011 is arranged in parallel. The number of side plates 312 is not limited to two. The two side plates 312 are arranged opposite each other and are fixedly connected to the opposite sides of the base plate 311 by screws, welding or any other existing fixing method. Each side plate 312 has not limited to two rows of height adjustment slots. The number of height adjustment slots 3121 in each row is not limited to three. The three height adjustment slots 3121 in each row are arranged at intervals along the direction perpendicular to the base plate 1011. Each side wall of the mounting base 32 has not limited to two rows of fixing holes. The number of fixing holes 321 in each row is not limited to seven. The seven fixing holes 321 in each row are arranged at intervals along the direction perpendicular to the base plate 1011. The number of adjustable locking parts 33 on each side plate 312 is not limited to four. It is worth mentioning that each side plate 312 is provided with a hanging ear plate 313 on its top. The hanging ear plate 313 is fixedly connected to the side plate 312 by screws, welding or any other existing fixing method. The support frame 31 is installed on the base plate 1011 by the hanging ear plate 313. The hanging ear plate 313 is fixedly connected to the base plate 1011 by screws, welding or any other existing fixing method.
[0038] In other embodiments, the side plate 312 of the support frame 31 is connected to the mounting base 32 by a guide rail and a slider. The height position of the clamping shaft drive device 34 is adjusted by adjusting the position of the slider.
[0039] See Figures 3 to 5 The adjustable locking component 33 provided in this embodiment includes a handle component 331 and a locking component 332 fixed to the handle component 331. The locking component 332 is provided with a threaded portion, which facilitates the operation of the adjustable locking component 33 and the adjustment of the height of the clamping shaft drive device 34.
[0040] See Figures 3 to 5 , Figure 7In this embodiment, an adjusting screw 314 is provided on the base plate 311. The axis of the adjusting screw 314 is perpendicular to the base plate 1011. The adjusting screw 314 is threadedly connected to the base plate 311, and the top end of the adjusting screw 314 abuts against the bottom of the clamping shaft drive device 34. In this way, after the adjustable locking component 33 is removed, the clamping shaft drive device 34 can be supported by the adjusting screw 314 to prevent the clamping shaft drive device 34 and the mounting base 32 from falling. The height position of the clamping shaft drive device 34 and the mounting base 32 can be adjusted by turning the adjustable locking component 33.
[0041] In other embodiments, a cylinder is provided on the base plate 311, and the cylinder shaft abuts against the bottom of the clamping shaft drive device 34.
[0042] See Figure 4 and Figure 5 In this embodiment, the side wall of the assembly base 32 is provided with a guide limiting plate 322, and the side plate 312 is provided with a guide limiting groove 3122 for the guide limiting plate 322 to move. The guide limiting groove 3122 extends in a direction perpendicular to the substrate 1011. The surface of the guide limiting plate 322 protrudes from the side wall surface of the assembly base 32. The length dimension of the guide limiting groove 3122 in the direction perpendicular to the substrate 1011 is greater than that of the guide limiting plate 322, and the width dimension of the guide limiting groove 3122 is basically the same as that of the guide limiting plate 322. In this way, the assembly base 32 can be guided when it moves up and down. In addition, the assembly base 32 can be restricted in the width direction of the guide limiting groove 3122.
[0043] See Figures 3 to 5 , Figure 7The shaft clamping drive device 34 provided in this embodiment includes a shaft clamp 341 rotatably mounted on the mounting base 32 for clamping the rotating shaft 201 of the rotor 200, and a rotary drive assembly 342 for rotating the shaft clamp 341. The shaft clamp 341 includes a hollow mounting shaft 3411 rotatably supported on the mounting base 32, a rod shaft 3412 disposed within the mounting shaft 3411 and movable along the axis of the mounting shaft 3411, and a flared opening for inserting the rotating shaft 201. The device comprises a clamping shaft 3413, a drive shaft 3414 for opening and closing the flared end, and a clamping shaft drive member 3415 for moving the rod shaft 3412. The end of the clamping shaft 3413 passes through the rod shaft 3412 and is fixed to the mounting shaft 3411. The drive shaft 3414 is movably mounted within the mounting shaft 3411 and located outside the clamping shaft 3413, and is fixed to the rod shaft 3412. In this embodiment, the rod shaft 3412 can rotate relative to the clamping shaft drive member 3415. The driving component 3415 is, but is not limited to, a cylinder. The clamping shaft driving component 3415 can drive the rod shaft 3412 to move relative to the mounting shaft 3411. The rotary driving assembly 342 is, but is not limited to, a motor synchronous belt driving assembly. The mounting shaft 3411 is keyed to the rotary driving assembly 342. The rod shaft 3412 and the mounting shaft 3411 are connected in a way that allows movement along the axis of the mounting shaft 3411 but prevents rotation. The end of the clamping shaft 3413 can move relative to the rod shaft 3412. Driven by the rotary drive assembly 342, the mounting shaft 3411 rotates around its axis and drives the rod shaft 3412, drive shaft 3414 and clamping shaft 3413 to rotate relative to the mounting base 32. The bottom end of the clamping shaft 3413 is fixed to the mounting shaft 3411. The clamping shaft drive 3415 drives the rod shaft 3412 and drive shaft 3414 to move relative to the mounting shaft 3411, thereby clamping and releasing the rotating shaft 201 of the rotor 200 at the flared end located at the top of the clamping shaft 3413.
[0044] See Figures 3 to 5 , Figure 7The clamping shaft drive device 34 provided in this embodiment also includes a wire pressing assembly 343. The wire pressing assembly 343 includes a wire pressing control block 3431, a wire pressing cylinder 3432 for pressing enameled wire (not shown) onto the hook portion of the commutator 203, a transition shaft 3433 rotatably mounted on the wire pressing control block 3431 and fixed to the wire pressing cylinder 3432, and a wire pressing drive member 3434 capable of driving the wire pressing control block 3431 to move. In this embodiment, the transition shaft 3433 is located between the drive shaft 3414 and the mounting shaft 3411, and the transition shaft 3433 can move relative to the mounting shaft 3411. 3434 is mounted on the mounting base 32. The wire pressing drive 3434 is, but is not limited to, a cylinder. It is fixedly connected to the wire pressing control block 3431 and drives the wire pressing control block 3431 to move in a direction perpendicular to the base plate 1011 (i.e., the axial direction of the wire pressing cylinder 3432). The wire pressing cylinder 3432 is connected to the wire pressing drive 3434 through the adapter shaft 3433. In this way, after the enameled wire is hung on the commutator 203 of the rotor 200, the wire pressing drive 3434 controls the wire pressing cylinder 3432 to move upward (towards the top shown in the figure) to press the wire end on the hook of the commutator 203 so that the enameled wire is hung on the commutator 203.
[0045] See Figures 5 to 7 The clamping shaft driving device 34 provided in this embodiment also includes a protective hook assembly 345. The protective hook assembly 345 includes an inner protective cylinder 3451 sleeved outside the wire pressing cylinder 3432, an outer protective cylinder 3452 sleeved outside the inner protective cylinder 3451, an inner cylinder driving member 3453 capable of driving the inner protective cylinder 3451 to move, and an outer cylinder driving member 3454 capable of driving the outer protective cylinder 3452 to move. The side wall of the inner protective cylinder 3451 is provided with a wire-passing hole (not shown in the figure) for the enameled wire to pass through. In this embodiment, both the inner cylinder driving member 3453 and the outer cylinder driving member 3454 are... Not limited to cylinders, the inner cylinder drive 3453 and the outer cylinder drive 3454 are respectively mounted on the mounting base 32. In this way, after the wire pressing tube 3432 presses the wire, the inner cylinder drive 3453 drives the inner protective tube 3451 to move upward (towards the top of the figure) and cover the outside of the wire pressing tube 3432. The enameled wire passes through the wire hole, and then the outer cylinder drive 3454 drives the outer protective tube 3452 to move upward (towards the top of the figure) and cover the outside of the inner protective tube 3451. This can prevent the enameled wire from contacting the commutator 203 during the winding process, thus protecting the commutator 203.
[0046] See Figures 3 to 5 , Figure 7 The support frame 31 provided in this embodiment is provided with a height limiting member 315 at the top, which is used to abut against the assembly seat 32 and restrict the movement of the assembly seat 32. The height limiting member 315 can be detachably connected to the support frame 31, so as to limit the height position of the assembly seat 32 and prevent the assembly seat 32 from being too high.
[0047] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions or improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
