Swing-angle guiding-needle winding system and swing module thereof

Abstract

The present disclosure provides a swing-angle guiding-needle winding system and a swing module thereof. The swing module is configured to connect a guiding needle to wind a wire around an electrode. The swing module includes a transmission motor and a connection rod. The transmission motor is disposed on a base. The guiding needle is pivotally connected to a bottom end of the base and has a wire input end and a wire output end opposite to each other. The connection rod includes a first end and a second end opposite to each other. The first end is connected to the transmission motor and driven by the transmission motor to displace the connection rod longitudinally relative to the base. Moreover, the second end is connected to the wire input end of the guiding needle. When the connection rod is displaced longitudinally, the second end drives the wire output end of the guiding needle to swing at an angle relative to the longitudinal direction.

Description

[Technical Field]

[0001] This case relates to a guide needle winding system, particularly a swing-angle guide needle winding system and its swing module. By combining the swing module with the guide needle to swing at an appropriate angle when traveling along the path, the angle between the guide needle and the wire exit direction is reduced, thereby reducing the tension stress concentration problem caused by the wire exit direction being too perpendicular to the guide needle, and thus stabilizing the winding quality. [Previous Technology]

[0002] Currently, electromechanical products are becoming increasingly sophisticated in design in response to performance requirements. The goal is to incorporate higher density wires into the existing electrode space to increase power per unit area. Under this requirement, a hooking method is usually used as the winding technique.

[0003] The hooking method allows the guide pin to be moved according to the outer size of the electrode and to be as close to the electrode as possible, so that the instability caused by height difference is reduced during the arrangement of the wire.

[0004] However, when a traditional guide needle system is used for winding, during the rising and falling sections of the winding process, the direction of the wire exit is perpendicular to and opposite to the direction of the guide needle movement. This can easily cause wear on the guide needle and damage to the wire's enameled layer due to prolonged use under high tension.

[0005] In view of this, it is necessary to provide a swing-angle guide needle winding system and its swing module. By combining the swing module with the guide needle to swing at an appropriate angle when traveling along the path, the angle between the guide needle and the wire exit direction can be reduced, thereby reducing the tension stress concentration problem caused by the wire exit direction being too perpendicular to the guide needle, thus stabilizing the winding quality and solving the deficiencies of the prior art. [Summary of the Invention]

[0006] The purpose of this invention is to provide a swing-angle guide needle winding system and its swing module. By combining the swing module with the guide needle, the guide needle can swing at an appropriate angle when traveling along the path, thereby reducing the angle between the guide needle and the wire exit direction, so as to reduce the tension stress concentration problem caused by the wire exit direction being too perpendicular to the guide needle, and thus stabilize the winding quality.

[0007] Another objective of this invention is to provide a swing-angle guide pin winding system and its swing module. The swing module uses a drive motor to control a ball screw to drive the connecting rod of the guide pin. When the ball screw moves upward, the guide pin swings downward (and vice versa), allowing the guide pin to swing to a suitable angle to match the winding path during the upward or downward displacement segment. This reduces the angle between the guide pin and the wire exit direction, preventing the concentration of force at the guide pin's angle and thus improving winding quality. On the other hand, when the guide pin is in lateral displacement, the swing module can extend the guide pin's swing angle into the electrode, which greatly shortens the distance between the wire exit end and the target electrode. Reducing the distance the wire falls to the target electrode further helps reduce wire routing disorder. By combining the swing module with the guide pin, the guide pin can swing vertically within a range of, for example, 0 to 135 degrees. For winding operations of high-tension yarns, the oscillating module can control the lead pin's exit end to oscillate longitudinally (e.g., 45 degrees) relative to the vertical direction on the upward longitudinal displacement path and the upper lateral displacement path; and control the lead pin's exit end to oscillate longitudinally (e.g., 135 degrees) relative to the vertical direction on the downward longitudinal displacement path and the lower lateral displacement path, thereby reducing tension. For winding operations of low-tension yarns, the oscillating module can control the lead pin's exit end to oscillate vertically, disabling the oscillation function to quickly complete the winding operation. Furthermore, when the oscillating module controls the lead pin to oscillate vertically (e.g., 0 degrees), the lead pin's exit end can also meet the requirement of vertical yarn hanging. Thus, the oscillating guide pin winding system and its oscillating module of this invention expand the space for process optimization, not only reducing process time but also reducing the distance the yarn falls, thereby reducing yarn routing disorder.

[0008] To achieve the aforementioned objective, this invention provides a swaying guide needle winding system, which is used to wind a wire onto an electrode. The swaying guide needle winding system includes a base, a guide needle, and a swaying module. The base is configured to move longitudinally and laterally relative to the electrode. The guide needle is pivotally mounted on the base and has opposite inlet and outlet ends. The base drives the guide needle to wind the wire onto the electrode along a winding path. The wire is introduced from the inlet end, exited through the outlet end, and then wound onto the electrode. The swaying module includes a drive motor and a connecting rod. The drive motor is mounted on the base. The connecting rod includes a first end and a second end that are opposite to each other. The first end is connected to a drive motor and is driven by the drive motor to move the connecting rod longitudinally relative to the base. The second end is connected to the inlet end of the guide needle. When the connecting rod moves longitudinally, the second end drives the outlet end of the guide needle to swing longitudinally. The winding path surrounds the electrode and includes an upward longitudinal displacement path, an upper lateral displacement path, a downward longitudinal displacement path, and a lower lateral displacement path. When the guide needle is on the upward longitudinal displacement path and the upper lateral displacement path, the swing module drives the outlet end of the guide needle to swing longitudinally to a first outlet angle. When the guide needle is on the downward longitudinal displacement path and the lower lateral displacement path, the swing module drives the outlet end of the guide needle to swing longitudinally to a second outlet angle. The first outlet angle is less than or equal to 90 degrees, and the second outlet angle is greater than or equal to 90 degrees.

[0009] In one embodiment, the swing module further includes a ball screw pivotally connected to the first end of the connecting rod, and a drive motor drives the ball screw to rotate so that the connecting rod moves longitudinally.

[0010] In one embodiment, the drive motor is a linear motor, which is connected to the first end of the connecting rod via a ball screw.

[0011] In one embodiment, the base includes a fixed support frame extending longitudinally, the top end of the fixed support frame being adjacent to the drive motor and the ball screw, the guide pin being pivotally connected to the bottom end of the fixed support frame via a bearing assembly, the bearing assembly being located between the inlet end and the outlet end, and the second end of the connecting rod being pivotally connected to the inlet end of the guide pin.

[0012] In one embodiment, the base further includes a slide rail assembly disposed between the fixed support frame and the ball screw, the assembly allowing the ball screw to move longitudinally relative to the fixed support frame.

[0013] In one embodiment, the lead end of the guide needle extends downward from the base, the guide needle has an initial angle relative to the longitudinal direction, and the swing module does not drive the guide needle to swing.

[0014] In one embodiment, the electrode includes a plurality of electrodes arranged around each other to form an annular frame, and the annular frame further includes a plurality of electrode slots, the plurality of electrodes and the plurality of electrode slots being arranged alternately to each other.

[0015] In one embodiment, the guide needle faces the outer ring surface of the annular frame from the outside to the inside to wind the wire onto the electrode, or faces the inner ring surface of the annular frame from the inside to the outside to wind the wire onto the electrode.

[0016] In one embodiment, the guide pin passes through the corresponding electrode groove when it is in the upward longitudinal displacement path or the downward longitudinal displacement path.

[0017] In one embodiment, the annular frame further includes a plurality of upper flanges and lower flanges, respectively located at the upper and lower edges of the plurality of electrodes, wherein when the guide pin is in the upper lateral displacement path, the longitudinal height of the lead-out end is lower than the upper flange, and when the guide pin is in the lower lateral displacement path, the longitudinal height of the lead-out end is higher than the lower flange, so as to shorten the distance between the lead-out end and the electrode.

[0018] In one embodiment, the guide needle includes a wire nozzle and a hollow portion. The wire nozzle is located at the outlet end, and the hollow portion passes through the inlet end and outlet end of the guide needle. The wire enters the hollow portion from the inlet end and then exits from the wire nozzle at the outlet end.

[0019] To achieve the aforementioned objective, this invention further provides a swing module, which is assembled with a connecting guide pin to wind the wire onto the electrode. The swing module includes a drive motor and a connecting rod. The drive motor is disposed on a base, and the guide pin is pivotally disposed at the bottom end of the base, having opposite inlet and outlet ends. The connecting rod includes a first end and a second end, opposite to each other. The first end is connected to the drive motor and is driven by the drive motor to move the connecting rod longitudinally relative to the base. The second end is connected to the inlet end of the guide pin, and when the connecting rod moves longitudinally, the second end causes the outlet end of the guide pin to swing relative to the longitudinal direction by an angle.

[0020] In one embodiment, the base drives the guide pin to wind the wire onto the electrode along the winding path. The wire is introduced from the inlet end, led out from the outlet end, and then wound onto the electrode. The winding path surrounds the electrode and includes an upward longitudinal displacement path, an upper lateral displacement path, a downward longitudinal displacement path, and a lower lateral displacement path. When the guide pin is on the upward longitudinal displacement path and the upper lateral displacement path, the swing module drives the outlet end of the guide pin to swing relative to the longitudinal direction to a first outlet angle. When the guide pin is on the downward longitudinal displacement path and the lower lateral displacement path, the swing module drives the outlet end of the guide pin to swing relative to the longitudinal direction to a second outlet angle. The first outlet angle is less than or equal to 90 degrees, and the second outlet angle is greater than or equal to 90 degrees.

[0022] Please refer to Figures 1 to 9. This invention provides a swivel-angle guide needle winding system 1, which is assembled to wind a wire 8 onto an annular frame 90, such as a stator 9. In this embodiment, the frame 90 includes a plurality of electrodes 91 and a plurality of electrode slot channels 92. The plurality of electrodes 91 are arranged in a ring to form the annular frame 90, and the electrodes 91 and electrode slots 92 are arranged alternately. When the wire 8 is wound, the swivel-angle guide needle winding system 1 and the annular frame 90 are relatively displaced, causing the wire 8 to wind around one of the winding target electrodes 91a among the plurality of electrodes 91. It should be noted that the relative displacement between the swivel-angle guide needle winding system 1 and the annular frame 90 may be, for example, longitudinal (vertical, Z-axis) and lateral (left and right, XY plane) displacement of the swivel-angle guide needle winding system 1, while the annular frame 90 is rotated. This invention is not limited to this. In this embodiment, the oscillating guide needle winding system 1 includes a base 10, a guide needle 20, and an oscillating module 2. Referring to Figures 1, 2, and 4, the base 10 is configured to allow for longitudinal and lateral displacement relative to the winding target electrode 91a. The guide needle 20 is pivotally mounted on the base 10, allowing it to oscillate relative to the base 10, and has an inlet end 21 and an outlet end 22 that are opposite to each other. In this embodiment, the guide needle 20 includes a wire nozzle 23 and a hollow portion 24. The wire nozzle 23 is located at the outlet end 22, and the hollow portion 24 penetrates both the inlet end 21 and the outlet end 22 of the guide needle 20. The wire 8 enters the hollow portion 24 from the inlet end 21 and exits from the wire nozzle 23 at the outlet end 22. Of course, the path and method by which the wire 8 is introduced into the guide needle 20 are not essential technical features limiting this invention and will not be elaborated upon here. In this embodiment, the base 10 can drive the guide pin 20 to wind the wire 8 onto the target electrode 91a along the winding path P by longitudinal and lateral displacement (and / or rotation of the annular frame 90). The wire 8 is introduced from the inlet end 21, exited from the outlet end 22, and then wound onto the target electrode 91a. Finally, the winding operation of all electrodes 91 on the annular frame 90 is completed sequentially. The following description is only based on a single target electrode and is not intended to limit this invention. In this embodiment, the swing module 2 includes a drive motor 30 and a connecting rod 40. The drive motor 30 is disposed on the base 10. The connecting rod 40 includes a first end 41 and a second end 42 that are opposite to each other. The first end 41 of the connecting rod 40 is connected to the drive motor 30 and is driven by the drive motor 30 to move the connecting rod 40 longitudinally relative to the base 10. In addition, the second end 42 of the connecting rod 40 is connected to the inlet end 21 of the guide pin 20. The guide pin 20 is pivotally mounted on the bottom end of the base 10. When the drive motor 30 drives the connecting rod 40 to move longitudinally, the second end 42 of the connecting rod 40 will cause the lead end 22 of the guide pin 20 to swing relative to the longitudinal direction by an angle between 0 degrees and 135 degrees.In other words, the swing module 2 in this case can swing the guide pin 20 to a suitable angle as needed, reduce the angle between the guide pin 20 and the wire body 8 in the direction of wire exit, avoid the problem of force being concentrated at the corner of the guide pin 20, and thus improve the winding quality.

[0023] It should be noted that, in this embodiment, the drive motor 30 is a linear motor, and the swing module 2 further includes a ball screw 50, which is pivotally connected to the first end 41 of the connecting rod 40 via a rotating shaft 43. When the drive motor 30 drives the ball screw 50 to rotate, it can drive the connecting rod 40 to move longitudinally. In this embodiment, the base 10 further includes a slide rail assembly 51, which is disposed between the fixed support frame 11 and the ball screw 50. The assembly allows the ball screw 50 to move longitudinally relative to the fixed support frame 11, thereby driving the connecting rod 40. In this embodiment, the base 10 includes a fixed support frame 11 extending longitudinally, with the top end of the fixed support frame 11 adjacent to the drive motor 30 and the ball screw 50. The guide pin 20 is pivotally connected to the bottom end of the fixed support frame 11 via a bearing assembly 12, which is located between the inlet end 21 and the outlet end 22. The connecting rod 40 is housed, for example, within the fixed support frame 11, and its second end 42 is pivotally connected to the inlet end 21 of the guide pin 20 via a pivot 44. When the drive motor 30 is not started, the ball screw 50 is not moved down from the base 10, the outlet end 22 of the guide pin 20 extends downward from the bottom end of the fixed support frame 11 of the base 10, and the guide pin 20 has an initial angle A0 relative to the longitudinal direction (see Figure 5). The swing module 2 does not drive the guide pin 20 to swing. When the drive motor drives the ball screw 50 to move down from the base 10, the ball screw 50, together with the slide rail assembly 51, drives the first end 41 of the connecting rod 40 to move down longitudinally. Since the second end 42 of the connecting rod 40 is connected to the inlet end 21 of the guide pin 20, when the connecting rod 40 moves down longitudinally, it will cause the guide pin 20, pivotally connected to the fixed support frame 11, to swing at an angle around the bearing assembly 12. In one embodiment, the drive motor drives the ball screw 50 to move slightly downward from the base 10, causing the connecting rod 40 to drive the guide pin 20's lead-out end 22 to swing relatively longitudinally to a first lead-out angle A1 (see Figure 6), for example, 45 degrees. In another embodiment, the drive motor drives the ball screw 50 to move downward from the base 10 to a lower end, causing the connecting rod 40 to drive the guide pin 20's lead-out end 22 to swing relatively longitudinally to a second lead-out angle A2 (see Figure 7), for example, 135 degrees. In other embodiments, the drive motor may also drive the ball screw 50 to move moderately downward from the base 10, causing the connecting rod 40 to drive the guide pin 20's lead-out end 22 to swing relatively longitudinally to a horizontal lead-out angle A3 (see Figure 8), i.e., 90 degrees. In other words, in this embodiment, the swing module 2, through the linkage of the drive motor 30, ball screw 50, slide rail assembly 51, and connecting rod 40, allows the guide pin 20 to swing relative to the longitudinal direction by an angle, for example, between 0 degrees and 135 degrees. Of course, the direction and angle range of the swing module 2 driving the guide pin 20 to swing can be adjusted according to actual application requirements.

[0024] Please refer to Figures 1, 2, and 9. It is worth noting that the winding path P winds the wire 8 around a single target electrode 91a in a clockwise direction. The winding path P includes, in a clockwise direction, an upward longitudinal displacement path p1, an upper lateral displacement path p2, a downward longitudinal displacement path p3, and a lower lateral displacement path p4, and repeats this cycle. Of course, in other embodiments, the winding operation of the wire 8 can also be performed counterclockwise, and this invention is not limited to this. In this embodiment, when the guide pin 20 is on the upward longitudinal displacement path p1 and the upper lateral displacement path p2, the swing module 2 drives the lead-out end 22 of the guide pin 20 to swing relative to the longitudinal direction to a first lead-out angle A1 (see Figure 6). Additionally, when the guide pin 20 is on the descending longitudinal displacement path p3 and the lower lateral displacement path p4, the swing module 2 drives the lead-out end 22 of the guide pin 20 to swing relative to the longitudinal direction to the second lead-out angle A2 (see Figure 7), thereby reducing the lead-out direction angle between the guide pin 20 and the thread body 8. In this embodiment, the first lead-out angle A1 (see Figure 6) is less than or equal to 90 degrees, and the second lead-out angle A2 (see Figure 7) is greater than or equal to 90 degrees. In other words, the swing range between the initial angle A0 (see Figure 5), the first lead-out angle A1 (see Figure 7), and the second lead-out angle A2 (see Figure 7) driven by the swing module 2 to swing the lead-out end 22 of the guide pin 20 is 0 degrees to 135 degrees. Of course, in other embodiments, the swing module 2 can also use the horizontal (i.e., 90 degrees) relative to the longitudinal direction of the lead-out end 22 of the guide pin 20 as the initial angle, and use a 45-degree downward swing as the first lead-out angle; and a 45-degree upward swing as the second lead-out angle. Of course, this case is not limited to this.

[0025] Refer to Figures 6, 9, and 10. In this embodiment, when the guide pin 20 moves along the upward longitudinal displacement path p1, the lead-out end 22 of the guide pin 20 extends from the outside to the inside towards the outer ring surface of the annular frame 90 (as shown in Figure 1) to the corresponding electrode groove 92a. The swing-angle guide pin winding system 1 will drive the guide pin 20 to move from bottom to top. At this time, the swing module 2 drives the lead-out end 22 of the guide pin 20 to swing relative to the longitudinal direction to the first lead-out angle A1, so that when the guide pin 20 moves from bottom to top, the lead-out direction angle between the guide pin and the wire can be reduced, and the problem of force being concentrated at the guide pin corner will not occur, thereby improving the winding quality.

[0026] Refer to Figures 6, 9, and 11. In this embodiment, when the guide pin 20 moves along the upper lateral displacement path p2, the lead-out end 22 of the guide pin 20 extends from the outside to the inside towards the outer ring surface of the annular frame 90 (as shown in Figure 1) and winds the upper edge of the target electrode 91a. The swing-angle guide pin winding system 1 drives the guide pin 20 to move laterally. At this time, the swing module 2 drives the lead-out end 22 of the guide pin 20 to swing relative to the longitudinal direction to the first lead-out angle A1, so that the distance between the lead-out end 22 of the guide pin 20 and the target electrode 91a can be greatly shortened when the guide pin 20 moves laterally, and collision with the upper flange 93a of the target electrode 91a is avoided. Since the longitudinal height of the lead-out end 22 of the guide pin 20 can be lower than the upper flange 93a when it moves along the upper lateral displacement path p2, the distance that the wire 8 falls to the target electrode 91a is effectively reduced, which helps to reduce the situation of wire routing disorder and thus improve the winding quality.

[0027] Refer to Figures 7, 9, and 12. In this embodiment, when the guide pin 20 moves along the descending longitudinal displacement path p3, the lead-out end 22 of the guide pin 20 extends from the outside to the inside towards the outer ring surface of the annular frame 90 (as shown in Figure 1) to the corresponding electrode groove 92b. The swing-angle guide pin winding system 1 will drive the guide pin 20 to move from top to bottom. At this time, the swing module 2 drives the lead-out end 22 of the guide pin 20 to swing relative to the longitudinal direction to the second lead-out angle A2, so that when the guide pin 20 moves from top to bottom, the lead-out direction angle between the guide pin 20 and the wire body 8 can be reduced, and the problem of force being concentrated at the corner of the guide pin 20 will not occur, thereby improving the winding quality.

[0028] Refer to Figures 7, 9, and 13. In this embodiment, when the guide pin 20 moves along the lower lateral displacement path p4, the lead-out end 22 of the guide pin 20 extends from the outside to the inside of the outer ring surface of the annular frame 90 (as shown in Figure 1) to the lower edge of the winding target electrode 91a. The swing-angle guide pin winding system 1 will drive the guide pin 20 to move laterally. At this time, the swing module 2 drives the lead-out end 22 of the guide pin 20 to swing relative to the longitudinal direction to the second lead-out angle A2, so that the distance between the lead-out end 22 of the guide pin 20 and the winding target electrode 91a can be greatly shortened when the guide pin 20 moves laterally, and collision with the lower flange 93b of the lower edge of the winding target electrode 91a is avoided. Since the longitudinal height of the lead-out end 22 of the guide pin 20 can be higher than the lower flange 93b when it moves along the lower lateral displacement path p4, the distance that the wire 8 falls to the winding target electrode 91a is effectively reduced, which helps to reduce the situation of wire routing disorder and thus improve the winding quality.

[0029] It can be seen that in this case, the swing module 2 drives the guide pin 20 to swing at an appropriate angle when traveling on the winding path P, thereby reducing the angle between the guide pin 20 and the wire exit direction of the wire body 8. This reduces the tension stress concentration problem caused by the wire exit direction being too perpendicular to the guide pin 20, thus stabilizing the winding quality. On the other hand, when the guide pin 20 is in lateral displacement, the swing module 2 can also drive the guide pin 20 to swing up and down, so that the wire exit end 22 of the guide pin 20 is close to the winding target electrode 91a while avoiding the upper flange 93a and the lower flange 93b. This greatly shortens the distance between the wire exit end 22 and the winding target electrode 91, reduces the distance the wire body 8 falls to the winding target electrode 91a, and further helps to reduce the situation of wire routing disorder. In other words, for winding operations of high-tension wires, the oscillating module 2 of this invention controls the lead-out end 22 of the guide pin 20 to oscillate relative to the longitudinal direction at a first lead-out angle A1, for example, 45 degrees, on the upward longitudinal displacement path p1 and the upper lateral displacement path p2; and controls the lead-out end 22 of the guide pin 20 to oscillate relative to the longitudinal direction at a second lead-out angle A2, for example, 135 degrees, on the downward longitudinal displacement path p3 and the lower lateral displacement path p4. This effectively reduces the tension generated in the wire 8 during winding operations. Of course, the values ​​of the first lead-out angle A1 and the second lead-out angle A2 can be adjusted according to actual application requirements. In other embodiments, for example, for winding operations of low-tension wires, the oscillating module 2 can also control the lead-out end 22 of the guide pin 20 to oscillate relative to the longitudinal direction at a horizontal lead-out angle A3, i.e., 90 degrees, on the upward longitudinal displacement path p1, the upper lateral displacement path p2, the downward longitudinal displacement path p3, and the lower lateral displacement path p4, to easily and quickly wind the wire 8 onto each electrode 91 of the annular frame 90. This case is not limited to this.

[0030] On the other hand, in this embodiment, the swing module 2 of the swing angle guide pin winding system 1 supports the swing angle of the guide pin 20 at the bottom of the fixed frame 11 through the drive motor 30, ball screw 50, slide rail assembly 51 and connecting rod 40, which allows the body structure of the guide pin 20 to be minimized to the greatest extent, making it suitable for winding operations of most products. For example, the swing angle guide pin winding system 1 can also wind the wire 8 onto the annular frame 90 of, for example, the stator 9a in an inward hook swing angle manner.

[0031] Referring to Figures 6, 9, and 14. In this embodiment, the guide pin 20 moves from the inside to the outside towards the inner annular surface of the annular frame 90 (as shown in Figure 1). When the swing-angle guide pin winding system 1 drives the guide pin 20 to move along the upward longitudinal displacement path p1 and the upper transverse displacement path p2, the swing module 2 drives the lead-out end 22 of the guide pin 20 to swing relative to the longitudinal direction to the first lead-out angle A1, so as to reduce the tension and effectively reduce the distance of the wire 8 falling to the electrode 91, thereby improving the winding quality.

[0032] Similarly, refer to Figures 7, 9 and 15. In this embodiment, the guide pin 20 moves from the inside to the outside towards the inner annular surface of the annular frame 90 (as shown in Figure 1). When the swing-angle guide pin winding system 1 drives the guide pin 20 to move along the descending longitudinal displacement path p3 and the lower end lateral displacement path p4, the swing module 2 drives the lead-out end 22 of the guide pin 20 to swing relative to the longitudinal direction to the second lead-out angle A2, so as to reduce the tension and effectively reduce the distance of the wire 8 falling to the electrode 91, thereby improving the winding quality.

[0033] Furthermore, referring to Figures 8, 9, and 16. In this embodiment, for the winding operation of a low-tension wire, the guide pin 20 moves from the inside to the outside towards the inner ring surface of the annular frame 90 (as shown in Figure 1). When the swing-angle guide pin winding system 1 drives the guide pin 20 to move along the upward longitudinal displacement path p1, the upper lateral displacement path p2, the downward longitudinal displacement path p3, and the lower lateral displacement path p4, the swing module 2 can also drive the wire outlet end 22 of the guide pin 20 to swing relative to the longitudinal direction to a horizontal wire outlet angle A3, that is, 90 degrees, so as to simply and quickly wind the wire 8 onto each electrode 91 of the annular frame 90.

[0034] Furthermore, referring to Figures 5 and 17, in this embodiment, when the swing module 2 controls the lead-out end 22 of the guide pin 20 to swing vertically to an initial angle A0, i.e., 0 degrees, the lead-out end 22 of the guide pin 20 can directly perform vertical hanging or wire arrangement operations corresponding to the upper edge of the annular frame 90 of the stator 9a. Thus, the swing-angle guide pin winding system 1 and its swing module 2 further expand the space for process optimization, not only reducing process time but also reducing the distance the wire 8 falls to reduce wire routing disorder. Of course, the combination variations of the swing-angle guide pin winding system 1 and its swing module 2 in conjunction with winding operations are not limited to the aforementioned embodiments; the aforementioned technical features can be combined and varied according to actual application requirements, and this embodiment is not limited to this.

[0035] In summary, this invention provides a swing-angle guide pin winding system and its swing module. The swing module, combined with the guide pin, allows for appropriate swing angles during path movement, reducing the angle between the guide pin and the wire exit direction. This reduces the tension stress concentration caused by the wire exit direction being too perpendicular to the guide pin, thereby stabilizing winding quality. The swing module uses a drive motor to control a ball screw to drive the guide pin's connecting rod. When the ball screw moves upward, the guide pin swings downward (and vice versa), allowing it to swing to a suitable angle to match the winding path during the upward or downward displacement segment. This reduces the angle between the guide pin and the wire exit direction, preventing force concentration at the guide pin's angle and improving winding quality. Furthermore, when the guide pin is in lateral displacement, the swing module can extend the guide pin's swing angle into the electrode, significantly shortening the distance between the wire exit end and the target electrode. Reducing the distance the wire falls to the target electrode further helps reduce wire routing disorder. By combining the swing module with the guide pin, the guide pin can swing relatively vertically longitudinally within a range of 0 to 135 degrees. For winding operations of high-tension yarns, the oscillating module can control the lead pin's exit end to oscillate longitudinally (e.g., 45 degrees) relative to the vertical direction on the upward longitudinal displacement path and the upper lateral displacement path; and control the lead pin's exit end to oscillate longitudinally (e.g., 135 degrees) relative to the vertical direction on the downward longitudinal displacement path and the lower lateral displacement path, thereby reducing tension. For winding operations of low-tension yarns, the oscillating module can control the lead pin's exit end to oscillate vertically, disabling the oscillation function to quickly complete the winding operation. Furthermore, when the oscillating module controls the lead pin to oscillate vertically (e.g., 0 degrees), the lead pin's exit end can also meet the requirement of vertical yarn hanging. Thus, the oscillating guide pin winding system and its oscillating module of this invention expand the space for process optimization, not only reducing process time but also reducing the distance the yarn falls, thereby reducing yarn routing disorder.
