[0009] According to some embodiments of the present application, when the two rotary power sources drive the two second gears in the same direction, the first gear swings the guide needle upward or downward.

[0010] According to some embodiments of the present application, when the two rotary power sources drive the two second gears in opposite directions, the first gear rotates the guide needle counterclockwise or clockwise.

The winding system 100 comprises an upper fixed frame 102, a lower fixed frame 101, a guide needle 120, a gear set 110, two rotary power sources (104a, 104b) and two shafts (106a, 106b). The two rotary power sources (104a, 104b) are arranged on the upper fixed frame 102. The lower ends of the two shafts (106a, 106b) are connected to the lower fixed frame 101, and the upper ends of the two shafts (106a, 106b) are connected to the rotary power sources (104a, 104b) respectively. The gear set 110 is connected to the two shafts (106a, 106b) and can slide up and down on the shafts by the driving of the two rotary power sources (104a, 104b), and the movement of the guide needle 120 is controlled by the action of the gear set 110.

[0070] Please refer to Figure 2 、 Figure 3 , Figure 2 Fig. 2 is a perspective view showing a gear set 110 according to an embodiment of the present application, Figure 3Figure 6 is a perspective view of another embodiment of the gear set 110. The gear set 110 is used to control the movement of the guide needle 120 so that the thread 130 outputted from the thread exit hole 120a of the guide needle 120 can be properly guided. The left and right fourth gears (112a, 112b) of the gear set 110 are respectively disposed on the two shafts (106a, 106b) and are respectively rotatably connected to one side of the two L-shaped frames (111a, 111b). The left and right third gears (114a, 114b) of the gear set 110 are respectively rotatably connected to the other side of the two L-shaped frames (111a, 111b) and are respectively engaged with the left and right fourth gears (112a, 112b). The central axes of the left and right third gears (114a, 114b) are respectively perpendicular to the central axes of the left and right fourth gears (112a, 112b). The rotation of the left and right fourth gears (112a, 112b) is respectively driven by the two rotary power sources (104a, 104b) to drive the rotation of the left and right third gears (114a, 114b). The left and right second gears (116a, 116b) of the gear set 110 are respectively rotatably connected to the two L-shaped frames (111a, 111b) and are respectively rotatably connected to the left and right third gears (114a, 114b). In other words, the central axis of the second gear 116a is aligned with the central axis of the third gear 114a and rotates synchronously, and the central axis of the second gear 116b is aligned with the central axis of the third gear 114b and rotates synchronously. The first gear 118 is rotatably connected to one side of the intermediate body 115, and the guide needle 120 is rotatably connected to the other side of the intermediate body 115 and fixed to the first gear 118 through the intermediate body 115, so that the guide needle 120 rotates synchronously with the first gear 118. The left and right second gears (116a, 116b) are respectively rotatably connected to the two opposite sides of the intermediate body 115 and are respectively engaged with the first gear 118. The front end of the cantilever frame 119 is fixed to the intermediate body 115, and the rear end of the cantilever frame 119 is provided with a pair of thread guide wheels (117a, 117b) through which the thread 130 passes. The first gear 118 is located between the guide needle 120 and the pair of thread guide wheels (117a, 117b). During winding, the thread 130 enters the thread entry hole 118b of the first gear 118 and is outputted from the thread exit hole 120a of the guide needle 120.

[0071] Please refer to Figure 4 which shows a magnified view of part of the gear set 110 and the guide needle 120 of an embodiment of the present application. Figure 4Only the left and right second gears (116a, 116b), the first gear 118 and the guide needle 120 are shown, and the middle body 115 and the cantilever frame 119 are removed, so as to clearly show the relationship with each other. In some embodiments of the present application, the left and right second gears (116a, 116b) are all engaged with the first gear 118, the central axis 116a' of the second gear 116a and the central axis 116b' of the second gear 116b are aligned with each other, and are both perpendicular to the central axis 118a of the first gear 118. In some embodiments of the present application, the guide needle 120 is aligned with the central axis 118a of the first gear 118. In some embodiments of the present application, the guide needle 120 has an elliptical cross section.

[0072] Please refer to Figures 5 to 8 , the relationship diagram of the gear set 110 operation and the guide needle 120 of an embodiment of the present application is shown. In Figure 5 , when the left and right second gears (116a, 116b) are both driven to rotate clockwise (refer to the arrow direction in the figure), under the interaction of the left and right second gears (116a, 116b) and the first gear 118, the guide needle 120 will be driven to swing upward along the arrow direction in the figure. In Figure 6 , when the left and right second gears (116a, 116b) are both driven to rotate counterclockwise (refer to the arrow direction in the figure), under the interaction of the left and right second gears (116a, 116b) and the first gear 118, the guide needle 120 will be driven to swing downward along the arrow direction in the figure. In summary, when the left and right second gears (116a, 116b) are driven to rotate in the same direction, under the action of the left and right second gears (116a, 116b) and the first gear 118, the guide needle 120 will be driven to swing upward or downward.

[0073] In Figure 7 , when the second gear 116a is driven to rotate counterclockwise and the second gear 116b is driven to rotate clockwise (refer to the arrow direction in the figure), under the interaction of the left and right second gears (116a, 116b) and the first gear 118, the guide needle 120 will be driven to rotate counterclockwise along the arrow direction in the figure. In Figure 8 , when the second gear 116a is driven to rotate clockwise and the second gear 116b is driven to rotate counterclockwise (refer to the arrow direction in the figure), under the interaction of the left and right second gears (116a, 116b) and the first gear 118, the guide needle 120 will be driven to rotate clockwise along the arrow direction in the figure. In summary, when the left and right second gears (116a, 116b) are driven to rotate in opposite directions, under the action of the left and right second gears (116a, 116b) and the first gear 118, the guide needle 120 will be driven to rotate counterclockwise or clockwise.

[0074] In some embodiments of the present application, all the gears of the gear set 110 are bevel gears.

[0075] Please refer to Figure 9 , Figure 10 , Figure 9 a perspective view of the guide needle 120 winding the target electrode 152 of the motor 150 of an embodiment of the present application, Figure 10 a plan view of the guide needle 120 winding the target electrode 152 (i.e. the target to be wound) of an embodiment of the present application. The mechanism controlling the movement of the guide needle 120 is the winding system 100 described above. The rotation swing angle of the guide needle 120 for each winding of the target electrode 152 comprises four stages: the upper pole-changing rotation section 140a, the lower pole-changing rotation section 140b, the upper swing angle section 140c, and the lower swing angle section 140d. The upper pole-changing rotation section 140a is the movement of the guide needle 120 above the target electrode 152. The lower pole-changing rotation section 140b is the movement of the guide needle 120 below the target electrode 152. The upper swing angle section 140c is the movement of the guide needle 120 on one side of the target electrode 152. The lower swing angle section 140d is the movement of the guide needle 120 on the other side of the target electrode 152. When the guide needle 120 is in the upper swing angle section 140c (e.g. ascending through the pole gap 154a), the angle between the guide needle 120 and the horizontal plane HL is a positive angle Al (see Figure 11 ). When the guide needle 120 is in the upper pole-changing rotation section 140a, the positive angle Al (see Figure 11 ) between the guide needle 120 and the horizontal plane HL is set to enable the guide needle 120 to swing away from the insulating protrusion 152a of the target electrode 152. When the guide needle 120 is in the lower swing angle section 140d (e.g. descending through the pole gap 154b), the angle between the guide needle 120 and the horizontal plane HL is a negative angle A2 (see Figure 12 ). When the guide needle 120 is in the lower pole-changing rotation section 140b, the negative angle A2 (see Figure 12 ) between the guide needle 120 and the horizontal plane HL is set to enable the guide needle 120 to swing away from the insulating protrusion 152b of the target electrode 152. When the guide needle 120 is in the upper pole-changing rotation section 140a and the lower pole-changing rotation section 140b, rotating the guide needle 120 enables the wire 130 to exit in the direction of the long axis of the elliptical shape of the guide needle 120 to reduce the probability of damage to the guide needle 120, and enables the guide needle 120 to swing away from the insulating protrusions 152a, 152b of the target electrode 152 to shorten the distance between the exit of the wire and the electrodes and reduce the distance of the copper wire falling to reduce the disorder of the wire. Although the above embodiment uses a motor electrode as the target to be wound, the target to be wound by the winding system and method of the present application is not limited thereto.

[0076] The winding system and method of the present application uses two motor rotating power sources to drive gear sets to form a needle swing angle and rotating composite mechanism, so that the needle can swing an appropriate angle when walking in the path. According to this planning, the following four advantages can be obtained.

[0077] (1) The swing angle method can reduce the angle between the needle and the copper wire, and can reduce the problem of excessive copper wire angle and force concentration on the needle corner, thereby improving the winding quality.

[0078] (2) When the needle moves horizontally, the needle can be rotated to a horizontal state and then swing an angle, which can greatly shorten the distance between the wire outlet end and the electrode, reduce the distance of the copper wire falling, and reduce the disorder of the wire arrangement.

[0079] (3) Since the design specification angle of the needle swing can reach 180 degrees, it can meet the demand of vertical wire hanging.

[0080] (4) Since the mechanism design allows the needle to rotate while swinging, it can achieve the advantages of rotating the needle and reducing the tension. Since the function is multiple, different winding rules can be selected for different functions. When the winding rule requires high tension, the rotation, swing or simultaneous rotation and swing can be turned on. When the tension requirement is not high, it can also return to the traditional fixed needle winding method. The user can select any winding path required to match each function module.

[0081] Although the present application has been disclosed as above, it is not intended to limit the present application. Any person skilled in the art can make various changes and modifications without departing from the spirit and scope of the present application. Therefore, the scope of protection of the present application shall be subject to the scope defined by the claims.
