[0030] like Figures 1 to 5As shown, the winding unit 100 provided in this embodiment includes: an annular base 10 having an inner hole 10a and at least one radial channel 11 communicating with the inner hole 10a, the inner hole 10a extending axially along the annular base 10, the at least one radial channel 11 passing through the central axis of the annular base 10 and the two ends of the at least one radial channel 11 respectively penetrating the outer surface of the base; at least one cable support 20 movably disposed within the at least one radial channel 11, the at least one cable support 20 including a first vertical portion 21, a second vertical portion 22 parallel to the first vertical portion 21, and a connecting portion 23 extending from the first vertical portion 21 through the inner hole 10a to the second vertical portion 22; at least one actuating member 30 for driving the at least one cable support 20 to move, the at least one actuating member 30 being rotatably mounted on the annular base 10 via a rotating shaft 40, the at least one actuating member 30 having a first connecting portion 31 and a second connecting portion 32, the first... The connecting portion 31 is connected to at least one cable tray 20 and is movable relative to at least one cable tray 20; and the operating lever 50 is used to drive at least one actuating member 30 to rotate about a pivot 40 relative to the annular base 10, one end of the operating lever 50 is built into the annular base 10 and is movable relative to the annular base 10 along the axial direction of the annular base 10, the second connecting portion 32 is connected to the operating lever 50 and is movable relative to the operating lever 50; the top surface of the first vertical portion 21, the second vertical portion The top surface of 22 abuts against the top surface of at least one radial channel 11, and the bottom surface of the first vertical part 21 and the bottom surface of the second vertical part 22 abut against the bottom surface of at least one radial channel 11. A cable routing nozzle 24 is provided on the first vertical part 21, the cable routing nozzle 24 has a cable routing hole 24a, a through hole 23a is formed on the connecting part 23, and the operating rod 50 has a cable supply hole 50a. The cable supply hole 50a, the inner hole 10a, the through hole 23a, and the cable routing hole 24a are connected in sequence.

[0031] The aforementioned winding unit 100 includes an annular base 10, a cable support 20, a toggle member 30, and an operating lever 50. The annular base 10 has an inner hole 10a and a radial channel 11. The cable support 20 is movably disposed within the radial channel 11. The cable support 20 includes a first vertical portion 21, a second vertical portion 22 parallel to the first vertical portion 21, and a connecting portion 23. The top surface of the first vertical portion 21 and the top surface of the second vertical portion 22 abut against the top surface of at least one radial channel 11, and the bottom surface of the first vertical portion 21 and the bottom surface of the second vertical portion 22 abut against the bottom surface of at least one radial channel 11. Thus, by adopting the structure of the first vertical portion 21 and the second vertical portion 22, the cable support 20 moves more stably within the radial channel 11, thereby ensuring cable uniformity, improving winding quality, and achieving precision wiring.

[0032] See Figures 1 to 5The winding unit 100 provided in this embodiment includes an annular base 10, a cable tray 20, a toggle member 30, and an operating lever 50.

[0033] See Figures 1 to 5 The annular base 10 provided in this embodiment has an inner hole 10a and a radial channel 11 communicating with the inner hole 10a. The inner hole 10a extends axially along the annular base 10, and its two ends penetrate the top and bottom surfaces of the annular base 10, respectively. The radial channel 11 passes through the central axis of the annular base 10, and its two ends penetrate the outer surface of the base, respectively. In this embodiment, the annular base 10 includes an upper seat body 12 and a lower seat body 13 connected to each other. The upper seat body 12 and the lower seat body 13 are connected by screws or welding. After all existing fixing methods are used for connection, the upper seat 12 and the lower seat 13 are connected to form a radial channel 11. The openings formed at both ends of the radial channel 11 are located on the outer surface of the upper seat 12, and the bottom surface of the radial channel 11 is located on the top surface of the lower seat 13. The number of radial channels 11 is not limited to three. The three radial channels 11 are arranged at equal intervals along the circumference of the annular base 10, that is, the three radial channels 11 are arranged at equal intervals around the central axis of the annular base 10. The included angle between adjacent radial channels 11 is not limited to 30°.

[0034] See Figures 1 to 5 The cable tray 20 provided in this embodiment is movably disposed within the radial channel 11. The cable tray 20 includes a first vertical portion 21, a second vertical portion 22 parallel to the first vertical portion 21, and a connecting portion 23 extending from the first vertical portion 21 through an inner hole 10a to the second vertical portion 22. A through hole 23a is formed on the connecting portion 23. The top surfaces of the first vertical portion 21 and the second vertical portion 22 abut against the top surface of the radial channel 11, and the bottom surfaces of the first vertical portion 21 and the second vertical portion 22 abut against the bottom surface of the radial channel 11, respectively. A cable nozzle 24 is provided on the first vertical portion 21, and the cable nozzle 24 has a cable routing hole 24. a. In this embodiment, the first vertical portion 21 and the second vertical portion 22 of the cable support 20 have the same height, and their bottom surfaces and top surfaces are on the same horizontal plane. The connecting portion 23 extends horizontally from the first vertical portion 21 to the second vertical portion 22. The through hole 23a is, but is not limited to, an oblong hole. The cable nozzle 24 is disposed on the first vertical portion 21, and the outer end of the cable nozzle 24 protrudes beyond the outer surface of the first vertical portion 21. Thus, by using the cable support 20 with the same height of the first vertical portion 21 and the second vertical portion 22, the movement of the cable support 20 within the radial channel 11 is more stable, thereby improving the cable quality.

[0035] See Figure 3 and Figure 4In this embodiment, the number of cable trays 20 is, but not limited to, three. The three cable trays 20 correspond one-to-one with the three radial channels 11. Each radial channel 11 is provided with one cable tray 20. It should be noted that the connecting parts 23 of the three cable trays 20 are located at different heights. That is, the connecting parts 23 of the three cable trays 20 are staggered from each other in the axial direction of the annular base 10. After assembly, the connecting parts 23 of the three cable trays 20 are stacked sequentially from bottom to top. In this way, since there are three cable trays 20, copper wire wiring at three positions on the stator can be performed simultaneously, saving process steps.

[0036] See Figures 3 to 5 The actuating member 30 provided in this embodiment is used to drive the ribbon cable bracket 20 to move within the radial channel 11. The actuating member 30 is rotatably mounted on the annular base 10 via a rotating shaft 40. The actuating member 30 has a first connecting part 31 and a second connecting part 32. The first connecting part 31 is connected to the ribbon cable bracket 20 and can move relative to the ribbon cable bracket 20. In this embodiment, the number of actuating members 30 is, but not limited to, three. The three actuating members 30 correspond one-to-one with the three ribbon cable brackets 20. The actuating members 30 are rotatably mounted in the mounting groove 13a of the lower seat 13 via the rotating shaft 40. The first connecting part 31 of each actuating member 30 is movably connected to the corresponding ribbon cable bracket 20. In this way, when the actuating member 30 rotates around the rotating shaft 40, it can push and pull the ribbon cable bracket 20 to move slightly within the radial channel 11, thereby enabling the ribbon cable nozzle 24 to precisely wire on the stator.

[0037] See Figure 1 , Figures 3 to 5The operating lever 50 provided in this embodiment is used to drive the actuating component 30 to rotate around the rotating shaft 40 relative to the annular base 10. One end of the operating lever 50 is built into the annular base 10 and can move relative to the annular base 10 along the axial direction of the annular base 10. The second connecting part 32 is connected to the operating lever 50 and can move relative to the operating lever 50. The operating lever 50 has a wire supply hole 50a, and the wire supply hole 50a, inner hole 10a, through hole 23a, and wire routing hole 24a are connected in sequence. In this embodiment, the enameled wire (not shown) used for stator winding passes through the wire supply hole 50a, inner hole 10a, through hole 23a, and wire routing hole 24a in sequence. The second connecting part 32 of each actuating component 30 is movable. Connected to the corresponding operating lever 50, the operating lever 50 is connected to an external drive mechanism (not shown). This drive mechanism can drive the operating lever 50 to move axially along the annular base 10. While the operating lever 50 moves, it will also have a slight displacement relative to the annular base 10. Thus, when the operating lever 50 moves axially relative to the annular base 10, it can drive the second connecting part 32 of the actuating member 30 to rotate around the rotating shaft 40. This causes the actuating member 30 to rotate relative to the annular base 10 around the axis of the rotating shaft 40, thereby causing the first connecting part 31 of the actuating member 30 to push the cable tray 20 and the cable nozzle 24 installed on the cable tray 20 to move within the radial channel 11.

[0038] See Figures 1 to 5 In this embodiment, a wire support 60 is provided in the inner hole 10a of the annular base 10. The wire support 60 is located above the connecting part 23 of the cable tray 20. The wire support 60 has a wire passage hole 60a communicating with the inner hole 10a. The wire passage hole 60a is located below the cable tray hole 24a of the cable tray nozzle 24. In this embodiment, the wire support 60 is fixed to the end face of the annular base 10 by screws, welding or any other existing fixing method. After the enameled wire enters the inner hole 10a and the wire passage hole 23a from the wire supply hole 50a, it will pass through the wire support 60 and then enter the cable tray hole 24a. In this way, by setting the wire support 60 above the connecting part 23 of the cable tray 20, the wire passing through the wire passage hole 23a can be guided to the cable tray hole 24a, avoiding the enameled wire from contacting the cable tray 20 and causing damage, thereby improving the cable tray quality.

[0039] See Figure 4 and Figure 5 In this embodiment, a guide sleeve 70 is provided in the wire passage hole 60a of the wire support 60 to allow the enameled wire to slide. The guide sleeve 70 is installed in the wire passage hole 60a and can be made of, but is not limited to, plastic material. While guiding the movement of the enameled wire, it can also prevent the wire from being scratched.

[0040] See Figures 3 to 5In this embodiment, the first connecting part 31 of the actuating member 30 has a spherical structure, and the cable bracket 20 has a mating groove 25a for the first connecting part 31 to be inserted and moved. The depth of the mating groove 25a is greater than the diameter of the first connecting part 31. Thus, when the actuating member 30 rotates, the first connecting part 31 slides relative to the mating groove 25a of the cable bracket 20.

[0041] Please continue reading Figures 3 to 5 In this embodiment, the cable tray 20 also includes an assembly portion 25 protruding from the bottom surface of the second vertical portion 22, and a mating groove 25a is formed on the bottom surface of the assembly portion 25. In this way, the distance between the first connecting portion 31 and the rotating shaft 40 is shorter, and the stroke of the cable tray 20 is also shorter, thereby achieving precision wiring.

[0042] In other embodiments, the assembly portion 25 may also be formed on the connecting portion 23 or the first vertical portion 21.

[0043] See Figures 3 to 5 In this embodiment, the second connecting portion 32 of the actuating member 30 has a spherical structure, and the operating lever 50 has a groove 50b for the second connecting portion 32 to be inserted and moved, the depth of which is greater than the diameter of the second connecting portion 32.

[0044] Please continue reading Figures 3 to 5 In this embodiment, the operating lever 50 includes a lever component 51 and a sliding sleeve component 52 nested on the end of the lever component 51. The lever component 51 and the sliding sleeve component 52 are fixedly connected by screws, welding or any other existing fixing method. A groove 50b is formed on the outer surface of the sliding sleeve component 52 and extends along the entire circumference of the sliding sleeve component 52.

[0045] In other embodiments, the rod component 51 and the sliding sleeve component 52 may be integrally formed.

[0046] See Figure 6 and Figure 7 The winding machine 200 provided in this embodiment includes a fixing disk 201 for fixing the stator 300, and the aforementioned winding unit 100 for extending into the stator 300. The winding unit 100 is movably disposed below the fixing disk 201. In this embodiment, the fixing disk 201 has teeth for engaging with a fixing part. The fixing disk 201 is connected to a disk drive unit (not shown). Thus, during winding, the disk drive unit drives the fixing disk 201 to rotate, and drives the stator 300 to rotate through the teeth. The winding unit 100 is raised and lowered relative to the fixing disk 201 through an external drive mechanism and enters the stator 300 to wind.

[0047] Please continue reading Figure 6 and Figure 7The inner winding machine 200 provided in this embodiment also includes a lower pressure seat 202 for pressing the stator 300 onto the fixed plate 201. The lower pressure seat 202 is movably disposed above the fixed plate 201. In this way, the lower pressure seat 202 cooperates with the fixed plate 201 to limit the position of the stator 300 and prevent the stator 300 from shifting position during the winding process.

[0048] 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.
