[0002] A winding machine is a device used to wind the stator of a motor during motor manufacturing. Its principle is to wind the enameled wire and fix it in the stator of the motor. During winding, a flipping mechanism is used to drive the wire nozzle to clamp the enameled wire for winding, and the winding process must be continuously flipped so that the enameled wire is wrapped around the inside of the motor stator. The existing winding machine flipping mechanism is generally used to wind larger motor stator coils. If used to wind the stator wire coils of micro motors, if the winding is too fast, it is difficult to ensure the tightness and consistency of the enameled wire wound on the stator. In addition, due to insufficient tension, routing deviation and other reasons, the winding routing is very messy, thus affecting the product quality and operating performance of the motor.

[0027] The present invention will be further described in detail below with reference to the embodiments and specific implementation methods.

[0028] Example

[0029] like Figure 1 、 Figure 2 、 Figure 3 、 Figure 4 and Figure 5 As shown, a winding flipping mechanism for an automatic winding machine for a micro-motor stator comprises a sleeve seat 1, a flip cylinder 2, upper and lower shafts 3, a linear ball bearing 4, a nozzle flipping bracket 5, a rotating shaft 6, a bearing 7, a wire wheel 8 and an alloy nozzle 9; a cylindrical shaft barrel is provided in the middle of the sleeve seat 1, which is passed through from top to bottom, and the sleeve seat 1 is vertically arranged in the middle of the flipping mechanism; the upper and lower shafts 3 are movably inserted in the shaft barrel of the sleeve seat 1, and the top ends of the upper and lower shafts 3 are connected to the driving end of the flip cylinder 2; a linear ball bearing 4 is provided on the lower inner side of the sleeve seat 1, a notch opening downward is provided in the middle of the bottom end of the sleeve seat 1, and an external fixing portion 11 is formed on both sides of the notch. ; A notch opening upward is provided in the middle of the wire nozzle flip bracket 5, and an internal fixing part 51 is formed on both sides of the notch; an axial hole is provided on the external fixing part 11 and the internal fixing part 51, and when the internal fixing part 51 is inserted into the external fixing part 11, the axial hole on the external fixing part 11 and the axial hole on the internal fixing part 51 are completely connected, and a bearing 7 is fixed in the axial holes on the external fixing part 11 and the internal fixing part 51 on both sides of the notch of the wire nozzle flip bracket 5; a wire wheel 8 is sleeved in the middle of the rotating shaft 6, and both ends of the rotating shaft 6 are respectively inserted and fixed in the two bearings 7 on both sides of the notch of the wire nozzle flip bracket 5; an alloy wire nozzle 9 is connected downwardly to the bottom of the wire nozzle flip bracket 5.

[0030] The nozzle flip bracket 5 includes a pressing portion 52 and a flip portion 53. The pressing portion 52 is arranged at an angle from bottom to top and backward on the upper portion of the nozzle flip bracket 5. The flip portion 53 is connected downwardly to the lower portion of the pressing portion 52, and the axial hole on the inner fixing portion 51 is located in the middle of the connection between the pressing portion 52 and the flip portion 53. This is equivalent to the pressing portion 52 and the flip portion 53 being connected at an angle up and down. Since bearings 7 are installed in the two axial holes of the inner fixing portions 51 on both sides, and a rotating shaft 6 is connected between the two bearings 7, when the pressing portion 52 is pressed downward by the upper and lower shafts 3, it will drive the flip portion 53 to flip, thereby driving the alloy nozzle 9 on the flip portion 53 to flip and wind with the enameled wire 14.

[0031] At the same time, in order to facilitate the feeding of the enameled wire 14 by the wire feeding machine and the routing of the wire during the flip winding, the front side of the sleeve seat 1 is also connected to a wire bracket 10, which is provided with a wire hole that passes through from top to bottom. The bottom front side of the sleeve seat 1 is vertically connected to a grinding tube 12, which is provided with a wire hole that passes through from top to bottom.

[0032] In addition, in order to reduce the wear of the enameled wire when it passes through the flip structure during the winding process, ceramic eyes 13 are provided in the wire hole on the wire bracket 10 and the upper end of the wire hole of the grinding tube 12.

[0033] The working principle of this winding turning mechanism is briefly described below: Figure 5 and Figure 6As shown, first, the end of the enameled wire 14 sent from the wire feeding machine is manually passed through the porcelain eye 13 in the wire hole on the wire holder 10, and then through the porcelain eye 13 at the upper end of the wire hole of the grinding tube 12, and finally through the grinding tube 12, and finally to the alloy wire nozzle 9. When winding the stator of the micro motor, when the enameled wire 14 needs to be routed downward in the stator, the external servo drive mechanism drives the entire winding flip mechanism up and down to drive the enameled wire 14 up and down. When the enameled wire 14 needs to be turned and routed, the flip cylinder 2 drives the upper and lower shafts 3 downward, so that the lower ends of the upper and lower shafts 3 press the top pressure part 52 of the nozzle flip bracket 5 downward. When the top pressure part 52 is squeezed from above, it will flip, thereby driving the flip part 53 to flip, and the flip part 53 then drives the alloy wire nozzle 9 to flip and turn. At this time, the alloy wire nozzle 9 has the enameled wire 14, so it also leads the enameled wire 14 to flip and turn and route backward. After the coated wire 14 is folded and turned, the external servo drive mechanism drives the entire winding flip mechanism to move upward and drive the enameled wire 14 to move upward. When the alloy wire nozzle 9 brings the enameled wire 14 to the top of the micro motor stator winding position, the flip cylinder 2 drives the upper and lower shafts 3 to move upward, and the lower ends of the upper and lower shafts 3 drive the top pressure part 52 of the wire nozzle flip bracket 5 to reset upward, thereby driving the flip part 53 to flip and reset, and the flip part 53 drives the alloy wire nozzle 9 to reset. At this time, the alloy wire nozzle 9 will bring the enameled wire 14 above to reset and move forward from the top of the micro motor stator winding position, thereby completing the winding of one circle inside the micro motor stator. This cycle can be completed multiple times.

[0034] In this example, the present invention comprises a sleeve seat 1, a tilting cylinder 2, an upper and lower shaft 3, a linear ball bearing 4, a nozzle tilting bracket 5, a rotating shaft 6, a bearing 7, a wire guide wheel 8, and an alloy nozzle 9. The tilting cylinder 2 drives the upper and lower shafts 3 within the sleeve seat 1, which in turn drives the nozzle tilting bracket 5 to rotate. The nozzle tilting bracket 5 then pulls the enameled wire 14 through the alloy nozzle 9. This shortens the tilting cycle time and improves winding efficiency. Specifically, a new winding trajectory is adopted, resulting in tight winding and excellent product arrangement. This tilting mechanism is independently developed, simple to operate, and compatible with a variety of product specifications. It offers fast winding speeds and stable operation. The design is novel, the structure is rational, and the practical application is effective.

[0035] The above is only a preferred embodiment of the winding flipping mechanism for the automatic winding machine of the micro motor stator of the present invention. It should be pointed out that for ordinary technicians in this field, several variations and improvements can be made without departing from the creative concept of the present invention, which all fall within the scope of protection of the present invention.
