Description

Guide needle winding device Technical Field

[0001] This case relates to a guide needle winding device, particularly a guide needle winding device with a swing angle compensation mechanism, which enables the guide needle to automatically compensate for the lateral horizontal displacement when swinging longitudinally, maintaining a fixed lateral horizontal displacement without moving the entire device or using an additional servo axis for compensation, effectively improving the swing angle speed while reducing costs. Background Technology

[0002] In response to performance requirements, electromechanical products are becoming increasingly sophisticated in their design, aiming to incorporate higher density wires into existing electrode spaces to increase power per unit area. To meet this requirement, a hooking method is typically used as the winding technique.

[0003] The winding method allows the guide pin to move according to the electrode's external dimensions and to be as close to the electrode as possible, reducing instability caused by height differences during wire arrangement. Furthermore, current winding techniques use swaying guide pins for high-tension, large-diameter wires to reduce tension and friction between the wire exit and the guide pin's exit hole. However, when the swaying guide pin swings up and down, the exit hole at the tip of the guide pin experiences lateral displacement (distance difference ΔX) and longitudinal displacement (ΔZ) due to the design position of the swaying guide pin's rotation center. Therefore, servo motors for lateral (X-axis) and longitudinal (Z-axis) displacement are needed to compensate for the offset caused by the swaying guide pin during the swaying motion. Since lateral and longitudinal displacements typically need to accommodate the weight of the entire guide pin winding device, it becomes increasingly difficult to keep pace with the ever-increasing demand for faster winding speeds, especially when using servo motors for lateral and longitudinal displacement to achieve the same winding speed as the swaying guide pin.

[0004] In view of this, it is necessary to provide a guide needle winding device with a swing angle compensation mechanism, which can automatically compensate for the lateral horizontal displacement when the guide needle swings longitudinally, maintain a fixed lateral horizontal displacement, without moving the entire device or using an additional servo axis for compensation, effectively improve the swing angle speed, reduce costs, and solve the deficiencies of the existing technology. Summary of the Invention

[0005] The purpose of this invention is to provide a guide needle winding device with a swing angle compensation mechanism, which can automatically compensate for the lateral horizontal displacement when the guide needle swings longitudinally, maintain a fixed lateral horizontal displacement, and eliminate the need to move the entire device or use an additional servo axis for compensation, thereby effectively improving the swing angle speed and reducing costs.

[0006] Another objective of this invention is to provide a guide needle winding device with a swing angle compensation mechanism. By utilizing a cam guide assembly and cam bearing group in conjunction with the sliding mechanism of the guide needle module, the guide needle body can automatically compensate for the lateral horizontal displacement during swing angle adjustments. This allows the swing-angle guide needle to swing up and down at extremely high speeds during winding while maintaining a fixed lateral horizontal displacement. Since the swing angle elongation compensation method can be constructed using a purely mechanical structure, the compensation value can be calculated without algorithms. Furthermore, the guide needle mechanism only moves the guide needle body during elongation compensation, greatly reducing the mass of the moving parts and significantly increasing the swing angle speed, thus achieving extremely high winding speeds during winding operations. Moreover, since the swing angle elongation compensation method of the swing angle compensation mechanism is a purely mechanical structure, no additional servo motor shaft is needed to compensate for the lateral horizontal displacement during winding operations, thereby reducing costs. The sway angle compensation mechanism features a cam curve plate at the rear end of the sway angle guide needle body. This curve controls the extension / retraction of the guide needle body as the sway angle increases, ensuring the lateral position of the sway angle guide needle relative to the exit point remains constant during swaying, facilitating the winding process. Because of the sway angle compensation mechanism of the guide needle winding device, the front end of the guide needle body can sway to a suitable angle and maintain a fixed lateral horizontal displacement in conjunction with the winding path during the rising or falling displacement segment. This reduces the angle between the guide needle front end and the exit direction of the wire, preventing force concentration at the guide needle corner and thus improving winding quality. Furthermore, when the guide needle body is horizontally displaced relative to the electrode, the front end of the guide needle body can extend into the electrode. This significantly shortens the distance between the front end and the target electrode, reducing the distance the wire falls to the target electrode and further reducing wire routing disorder. For winding operations involving high-tension yarn, the oscillation module can control the guide pin body to oscillate downwards by, for example, 45 degrees on the upward vertical displacement path and the upper horizontal displacement path; and control the guide pin body to oscillate upwards by, for example, 45 degrees on the downward vertical displacement path and the lower horizontal displacement path, thereby reducing tension. Of course, regardless of the longitudinal oscillation angle of the guide pin body, the lateral position of the lead-out point can be maintained unchanged. Therefore, the guide pin winding device of this invention does not require an additional servo motor shaft to compensate for the offset horizontal displacement during winding operations, thus reducing operating costs and process time, and also reducing the distance the yarn falls to reduce yarn routing disorder. However, this invention is not limited to this.

[0007] To achieve the aforementioned objectives, this invention provides a guide needle winding device for winding a wire onto an electrode. The guide needle winding device includes a guide needle module, a base, a rotating module, a cam guide assembly, and a cam bearing assembly. The guide needle module includes a guide needle body and a guide needle rotating part, wherein the guide needle body extends through the guide needle rotating part along a first axial direction and includes a front end and a rear end opposite to each other, allowing the guide needle body to slide relative to the guide needle rotating part along the first axial direction. The rotating module is pivotally disposed between the base and the guide needle rotating part of the guide needle module, driving the guide needle module to swing vertically up and down relative to the base about a second axial direction, wherein the second axial direction is perpendicular to the first axial direction. The cam guide assembly is fixed to the base and includes at least one guide groove, spatially disposed opposite to the rear end. The cam bearing assembly is sleeved onto the rear end of the guide needle body and includes at least one engaging portion that engages with at least one guide groove of the cam guide assembly. When the rotating module drives the guide needle module to swing angle, the guide needle body, through the engagement of at least one engaging portion of the cam bearing assembly at the rear end with at least one guide groove of the cam guide assembly, drives the front end of the guide needle body to slide a distance relative to the second axis along the first axis and maintains the front end at a fixed lateral displacement.

[0008] In one embodiment, the rotation module includes a gear set and a drive motor. The drive motor drives the guide pin rotation part to swing vertically up and down relative to the base with the second axis as the center through the gear set.

[0013] In one embodiment, there is a relationship between the swing angle of the front end of the guide needle body relative to the base and the length of the guide needle body, so as to obtain a cam curve compensation to keep the front end at zero lateral displacement.

[0014] In one embodiment, the position coordinates of the front end of the guide needle body relative to the second axis are (X1, Z1). After the front end of the guide needle body swings longitudinally by an angle θ, the coordinates of the rear end compensation are (X2, Z2), which conforms to:

[0015] Where L is the length of the guide needle body.

[0016] In one embodiment, the angle range is between 45° and -45°.

[0017] In one embodiment, the front end of the guide needle body winds the wire onto the electrode along the winding path. The wire is introduced from the rear end of the guide needle body, exited from the front end, and then wound onto the electrode.

[0018] In one embodiment, the winding path surrounds the electrode and includes an upward vertical displacement path, an upper horizontal displacement path, a downward vertical displacement path, and a lower horizontal displacement path. The guide needle body swings downward to a first angle during the upward vertical displacement path and the upper horizontal displacement path, and swings upward to a second angle during the downward vertical displacement path and the lower horizontal displacement path.

[0019] In one embodiment, the first angle and the second angle are 45°.

[0020] To achieve the aforementioned objectives, this application also provides a guide needle winding device, which is used to wind a wire onto an electrode. The guide needle winding device includes a guide needle module, a base, a rotating module, and a guiding module. The guide needle module includes a guide needle body portion, which is disposed along a first axial direction and includes a front end and a rear end portion that are opposite to each other. The rotating module is pivotally disposed between the base and the guide needle module, and is used to drive the guide needle module to swing vertically up and down relative to the base at an angle about a second axial direction, wherein the second axial direction is perpendicular to the first axial direction. The guiding module is connected to the rear end portion of the guide needle body portion, and is used to drive the guide needle body portion to slide upward along the first axial direction. When the rotating module drives the guide needle module to swing at an angle, the guiding module causes the front end portion of the guide needle body portion to slide a distance relative to the second axial direction along the first axial direction, and maintains the front end portion at a fixed lateral displacement.

[0021] In one embodiment, the guide needle module includes a guide needle rotating part, and the rotating module includes a gear set and a drive motor. The drive motor drives the guide needle rotating part to swing vertically up and down about a second axis through the gear set.

[0022] In one embodiment, the guide needle body and the guide needle rotating part are connected by a ball spline shaft.

[0023] In one embodiment, the guide needle module includes a guide needle seat, a guide needle body fixed on the guide needle seat, a guide needle seat slidably connected to a guide needle rotating part, and a guide module drives the guide needle body and the guide needle seat to slide relative to the guide needle rotating part in a first axial direction.

[0024] In one embodiment, the guide needle seat and the guide needle rotating part are connected by a slide rail assembly, so that the guide module drives the guide needle body and the guide needle seat to slide relative to the guide needle rotating part in the first axis.

[0025] In one embodiment, the guiding module includes a cam guiding assembly and a cam bearing assembly. The cam guiding assembly is fixed to the base and includes at least one guide groove, spatially disposed relative to the rear end. The cam bearing assembly is sleeved onto the rear end of the guide needle body and includes at least one engaging portion that engages with at least one guide groove of the cam guiding assembly. When the rotating module drives the guide needle module to swing by an angle, the guide needle body, through the engagement of at least one engaging portion of the cam bearing assembly at the rear end with at least one guide groove of the cam guiding assembly, drives the front end of the guide needle body to slide a displacement distance relative to the guide needle rotating portion along a first axial direction, and maintains the front end at a fixed lateral displacement.

[0026] In one embodiment, the electrode includes a plurality of electrodes arranged in a ring to form an annular frame. The annular frame also includes a plurality of electrode grooves. The plurality of electrodes and the plurality of electrode grooves are arranged alternately to each other.

[0046] Please refer to Figures 1 to 6. This invention provides a guide needle winding device 1, which is assembled to wind a wire 8 onto an annular frame 90, such as a stator 9. In this embodiment, the annular frame 90 includes multiple electrodes 91 and multiple electrode slots 92. The multiple electrodes 91 are arranged around the annular frame 90, and the electrodes 91 and electrode slots 92 are arranged alternately. When the wire 8 is wound, the guide needle winding device 1 and the annular frame 90 are relatively displaced, causing the wire 8 to wind around one of the multiple electrodes 91 target electrodes 91a. It should be noted that the relative displacement between the guide needle winding device 1 and the annular frame 90 may be, for example, the guide needle winding device 1 swinging longitudinally (up and down, i.e., in the Z-axis direction), while the annular frame 90 is rotated. This invention is not limited to this. In this embodiment, the guide needle winding device 1 includes a guide needle module 20, a base 10, a rotation module 30, and a guide module 40. The guide module 40 is, for example, composed of a cam guide assembly 41 and a cam bearing assembly 43. Please refer to Figures 1, 2, 3, and 4. In this embodiment, the guide needle module 20 includes a guide needle body 22 and a guide needle rotating part 25. The guide needle body 22 extends through the guide needle rotating part 25 along a first axis C1 and includes a front end 23 and a rear end 24 opposite to each other. The guide needle body 22 allows sliding back and forth relative to the guide needle rotating part 25 along the first axis C1. The rotating module 30 is pivotally disposed between the base 10 and the guide needle rotating part 25 of the guide needle module 20, and is configured to drive the guide needle module 20 to swing up and down relative to the base 10 in the longitudinal direction (i.e., the Z-axis direction) around a second axis C2, wherein the second axis C2 is perpendicular to the first axis C1. In this embodiment, the cam guide assembly 41 is fixed to the base 10 and includes at least one guide groove 42. The at least one guide groove 42 is spatially disposed relative to the rear end 24 of the guide needle body 22. The inner ring 431 of the cam bearing assembly 43 is sleeved onto the rear end 24 of the guide needle body 22, and includes at least one engaging portion 44 that engages with at least one guide groove 42 of the cam guide assembly 41. In this embodiment, when the rotating module 30 drives the guide needle module 20 to swing, the guide needle body 22, through the engagement of at least one engaging portion 44 of the cam bearing assembly 43 on the rear end 24 with at least one guide groove 42 of the cam guide assembly 41, drives the front end 23 of the guide needle body 22 to slide a distance relative to the second axis C2 along the first axis C1, and maintains the front end 23 of the guide needle body 22 at a fixed lateral (i.e., X-axis) displacement.

[0047] In this embodiment, the guide needle module 20 is displaced relative to the winding target electrode 91a. In this embodiment, the guide needle body 22 is hollow, for example, extending through the front end 23 and the rear end 24 along the first axial direction C1. The front end 23 is, for example, a wire nozzle. The wire 8 is guided into the guide needle body 22 via the wire guide wheel 45 at the rear end 24, and then exits from the wire nozzle at the front end 23. Of course, the path and method of the wire 8 entering the guide needle body 22 are not essential technical features limiting this invention, and will not be described in detail here. In this embodiment, the guide needle module 20 can be driven to wind the wire 8 onto the winding target electrode 91a along the winding path P by longitudinal (i.e., Z-axis direction) displacement and transverse (i.e., X-axis direction) displacement (and / or rotation of the annular frame 90). The wire 8 is introduced from the rear end 24, exited from the front end 23, and then wound onto the winding target electrode 91a. Finally, the winding operation of all electrodes 91 on the annular frame 90 is completed sequentially. The following description is based on a single winding target electrode 91a and is not intended to limit the scope of this invention.

[0048] Please refer to Figures 1 to 9. In this embodiment, the rotation module 30 includes a gear set 31 and a drive motor 32. The drive motor 32 drives the guide needle rotation part 25 to swing up and down relative to the base 10 in the longitudinal direction (i.e., the Z-axis direction) with the second axis C2 as the center. In addition, in this embodiment, the guide needle body part 22 and the guide needle rotation part 25 are connected by a ball spline shaft 27. The guide needle body part 22 can rotate relative to the guide needle rotation part 25 with the first axis C1 as the center. The guide needle module 20 also includes a guide needle seat 21. The guide needle body part 22 is fixed on the guide needle seat 21, and the guide needle seat 21 is slidably connected to the guide needle rotation part 25. In this embodiment, the guide needle body part 22 and the guide needle seat 21 can slide relative to the guide needle rotation part 25 in the first axis C1 by being driven by the guide module 40. Since the guide needle seat 21 and the guide needle rotating part 25 can be connected by the slide rail assembly 26, the guide needle body 22 and the guide needle seat 21 will slide synchronously along the first axial direction C1 when driven. In other words, the meshing action of at least one engaging part 44 and at least one guiding groove 42 can drive the guide needle body 22 and the guide needle seat 21 to slide relative to the guide needle rotating part 25 along the first axial direction C1. It should be noted that in this embodiment, when the guide needle module 20 winds the wire 8 onto the winding target electrode 91a along the winding path P, the front end 23 of the guide needle body 22 will be relatively displaced along the winding path P and should be maintained in a fixed lateral (i.e., X-axis direction) position. During the winding operation, when the drive motor 32 drives the guide needle rotating part 25 to swing up and down by an angle θ relative to the base 10 in the longitudinal (i.e., Z-axis direction) direction with the second axial direction C2 as the center through the gear set 31, the initial lateral position of the front end 23 of the guide needle body 22 will be moved away due to the swing of the guide needle body 22. However, the engagement of the guide needle body 22 with the meshing part 44 and at least one guide groove 42 can drive the front end 23 of the guide needle body 22 to slide relative to the guide needle rotating part 25 on the first axis C1, further compensating for the lateral (i.e. X-axis direction) displacement difference caused by the swing angle θ.

[0049] In this embodiment, the horizontally positioned and non-oscillating state of the guide needle body 22 is defined as an initial state, as shown in FIG7. The guide needle body 22 is arranged along the first axis C1 and parallel to the X-axis. The second axis C2 passes perpendicularly through the first axis C1. The initial lateral distance L0 of the front end 23 of the guide needle body 22 relative to the second axis C2 can be regarded as the fixed lateral distance that the guide needle module 20 and the stator 9 (see FIG2) should maintain during the winding operation.

[0050] As shown in Figure 8, when the drive motor 32 drives the guide needle rotating part 25 to swing downward by an angle θ relative to the base 10 in the longitudinal direction (i.e., the Z-axis direction) with the second axis C2 as the center, the initial lateral position of the front end 23 of the guide needle body part 22 will generate a lateral distance difference ΔX due to the swing of the guide needle body part 22. However, since the meshing part 44 of the cam bearing assembly 43 and the guide groove 42 of the cam guide assembly 41 maintain mutual meshing, when the front end 23 of the guide needle body 22 swings downward with the second axis C2 as the center, the meshing action of the meshing part 44 and the guide groove 42 allows the cam bearing assembly 43 to push against the rear end 24 of the guide needle body 22, thereby driving the guide needle body 22 and the guide needle seat 21 to slide and protrude relative to the guide needle rotating part 25 on the first axis C1, thereby compensating for the lateral distance difference ΔX caused by the swing of the guide needle body 22, and realizing that the front end 23 of the guide needle body 22 can maintain a fixed lateral distance during the winding operation, that is, the lateral (i.e., the X-axis direction) displacement is zero.

[0051] Similarly, as shown in Figure 9, when the drive motor 32 drives the guide needle rotating part 25 to swing upward by an angle θ relative to the base 10 in the longitudinal direction (i.e., the Z-axis direction) with the second axis C2 as the center, the initial lateral position of the front end 23 of the guide needle body part 22 will generate a lateral distance difference ΔX due to the swing of the guide needle body part 22. However, since the meshing part 44 of the cam bearing assembly 43 and the guide groove 42 of the cam guide assembly 41 maintain mutual meshing, when the front end 23 of the guide needle body 22 swings downward with the second axis C2 as the center, the meshing action of the meshing part 44 and the guide groove 42 allows the cam bearing assembly 43 to push against the rear end 24 of the guide needle body 22, thereby driving the guide needle body 22 and the guide needle seat 21 to slide and protrude relative to the guide needle rotating part 25 on the first axis C1, thereby compensating for the lateral distance difference ΔX caused by the swing of the guide needle body 22, and realizing that the front end 23 of the guide needle body 22 can maintain a fixed lateral distance during the winding operation, that is, the lateral (X-axis direction) displacement is zero.

[0052] As can be seen from the above, in this embodiment, there is a relationship between the swing angle θ of the front end 23 of the guide needle body 22 relative to the base 10 and the length of the guide needle body 22, so as to obtain a cam curve compensation, so that the cam curve compensation value is equal to the initial lateral position of the front end 23 of the guide needle body 22, which generates a lateral distance difference ΔX due to the swing of the guide needle body 22, thereby achieving the requirement that the front end 23 of the guide needle body 22 maintains a lateral displacement of zero.

[0053] Figure 10 is a diagram showing the relationship between the swing angle and length of the guide needle body and the cam curve compensation in the guide needle winding device of the preferred embodiment of this invention. For ease of explanation, the guide needle body 22, for example, has a length L. In the initial state, the second axis C2 passes through the midpoint of the guide needle body 22, and the second axis C2 has an initial lateral distance L / 2 from the front end 23 and the rear end 24. If the guide needle rotating part 25 swings upward relative to the base 10 in the longitudinal direction (i.e., the Z-axis direction) with the second axis C2 as the center, the coordinates of the front end 23 of the guide needle body 22 relative to the second axis C2 can be marked as (X1, Z1), X1 = L / 2. However, in order to maintain the requirement that the front end 23 of the guide needle body 22 has zero displacement in the lateral direction (i.e., the X-axis direction), after the front end 23 of the guide needle body 22 swings in the longitudinal direction by an angle θ, the compensated coordinates of the rear end 24 can be marked as (X2, Z2), which should meet the following requirements:

[0054] In this embodiment, the cam guide assembly 41 and guide groove 42 can be constructed from a cam curve plate. The curve trajectory of the guide groove 42 of the cam guide assembly 41 can be designed to complete the required cam curve compensation based on the coordinate (X2, Z2) change of the rear end 24 compensation, so that the front end 23 maintains zero lateral displacement. In other words, the curve of the guide groove 42 can control the lengthening / shortening of the guide needle body 22 with the size of the swing angle θ, thereby ensuring that the lateral (i.e., X-axis direction) position of the swing angle guide needle relative to the front end 23 (lead point) remains unchanged during the swing angle, which is beneficial for the winding process. It should be emphasized that the method of compensating for the swing angle of the guide needle body 22 by using the trajectory design of the guide groove 42 of the cam guide assembly 41 can be constructed by a purely mechanical structure. During the winding operation, there is no need to add an additional servo motor shaft to compensate for the lateral horizontal displacement, thus reducing costs.

[0055] Furthermore, in this embodiment, at least one guide groove 42 and at least one engaging portion 44 are symmetrically paired relative to the first axial direction C1, so that the engagement of the engaging portion 44 and the guide groove 42 can smoothly drive the guide needle body portion 22 to slide relative to the second axial direction C2 along the first axial direction C1 via the cam bearing assembly 43. Similarly, the gear set 31 and the drive motor 32 of the rotating module 30 can also be paired to smoothly drive the guide needle rotating portion 25 to swing longitudinally relative to the base 10 with the second axial direction C2 as the center. Of course, this invention is not limited to this.

[0056] As can be seen from the above, the guide needle winding device 1 of this invention, through the aforementioned swing angle compensation mechanism, enables the front end 23 of the guide needle body 22 to swing in coordination with the winding diameter and maintain a fixed lateral horizontal displacement, reducing the angle between the front end of the guide needle and the exit direction of the thread, thus preventing the problem of force concentration at the guide needle corner and improving the winding quality. The following further explains that the guide needle winding device 1 of this invention allows the guide needle to swing to a suitable angle in coordination with the winding path and maintain a fixed lateral horizontal displacement.

[0057] Please refer to Figures 1, 2, and 11. It should be noted that during the winding operation of the wire 8, the guide needle winding device 1 and the annular frame 90 are relative to each other, causing the wire 8 to wind around one of the multiple electrodes 91 target electrode 91a. The relative displacement between the guide needle winding device 1 and the annular frame 90 can be, for example, the guide needle winding device 1 swinging longitudinally (up and down, i.e., in the Z-axis direction), while the annular frame 90 is rotated. For ease of explanation, Figures 12 to 15 illustrate the guide needle body 22 winding around a single target electrode 91a, without limiting the scope of this invention. In this embodiment, the winding path P winds the wire 8 around the single target electrode 91a in a clockwise direction. The winding path P sequentially includes an upward vertical displacement path p1, an upper horizontal displacement path p2, a downward vertical displacement path p3, and a lower horizontal displacement path p4 in a clockwise direction, and repeats this cycle. Of course, in other embodiments, the winding operation of the thread 8 can also be performed counterclockwise, and this invention is not limited to this. In this embodiment, when the guide needle 20 is on the upward vertical displacement path p1 and the upper horizontal displacement path p2, the rotation module 30 drives the guide needle module 20 to swing downward to the first angle θ (see Figure 8), and the guide module 40 drives the front end 23 of the guide needle body 22 to slide forward and protrude, maintaining a fixed lateral (i.e., X-axis direction) position for upward winding, thereby reducing the angle between the guide needle 20 and the thread 8 in the exit direction. In addition, when the guide needle module 20 is on the downward vertical displacement path p3 and the lower horizontal displacement path p4, the rotation module 30 drives the guide needle module 20 to swing downward to the second angle θ (see Figure 9), and the guide module 40 drives the front end 23 of the guide needle body 22 to slide forward and protrude, maintaining a fixed lateral (i.e., X-axis direction) position for upward winding, thereby reducing the angle between the guide needle 20 and the thread 8 in the exit direction. In this embodiment, the first angle θ (see Figure 8) and the second angle θ (see Figure 9) are, for example, 45°. In other embodiments, the first angle θ and the second angle θ are not limited to fixed values ​​and are not equal. The guide needle winding device 1 of this invention, through the aforementioned swing angle compensation mechanism, can keep the front end 23 of the guide needle body 22 on the winding path P regardless of how the first angle θ and the second angle θ change. Of course, this invention is not limited to this.

[0058] Referring to Figures 8, 11, and 12. In this embodiment, when the guide needle module 20 moves relative to the winding target electrode 91a along the upward vertical displacement path p1, the front end 23 of the guide needle body 22 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, and the guide needle module 20 of the guide needle winding device 1 moves from bottom to top relative to the winding target electrode 91a. At this time, the rotation module 30 drives the guide needle module 20 to swing downward to the first angle θ (see Figure 8), and the guide module 40 drives the front end 23 of the guide needle body 22 to slide forward and protrude, maintaining a fixed lateral (i.e., X-axis direction) position for upward winding, thereby reducing the angle between the front end 23 of the guide needle body 22 and the wire body 8 in the wire exit direction, preventing the problem of force concentration at the guide needle corner, and thus improving the winding quality.

[0059] Referring to Figures 8, 11, and 13. In this embodiment, when the guide needle module 20 is displaced relative to the winding target electrode 91a along the upper horizontal displacement path p2, the front end 23 of the guide needle body 22 extends from the outside to the inside towards the outer ring surface of the annular frame 90 (as shown in Figure 1) to the upper edge of the winding target electrode 91a, and the guide needle module 20 of the guide needle winding device 1 is horizontally displaced relative to the winding target electrode 91a. At this time, the rotation module 30 maintains the downward swing of the guide needle module 20 to the first angle θ (see Figure 8), and the guide module 40 drives the front end 23 of the guide needle body 22 to slide forward and protrude, maintaining a fixed lateral (i.e., X-axis direction) position, so that the distance between the front end 23 and the winding target electrode 91a can be greatly shortened when the guide needle module 20 is horizontally displaced, and collision with the upper flange 93a of the upper edge of the winding target electrode 91a is avoided. Since the longitudinal height of the front end 23 of the guide needle body 22 can be lower than the upper flange 93a when it is in the upper horizontal displacement path p2, the distance of the wire 8 falling to the winding target electrode 91a is effectively reduced, which helps to reduce the wire routing disorder and thus improve the winding quality.

[0060] Referring to Figures 9, 11, and 14. In this embodiment, when the guide needle module 20 moves relative to the winding target electrode 91a along the descending vertical displacement path p3, the front end 23 of the guide needle body 22 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 rotation module 30 drives the guide needle module 20 to swing upward to the second angle θ (see Figure 9), and the guide module 40 drives the front end 23 of the guide needle body 22 to slide forward and protrude, maintaining a fixed lateral (i.e., X-axis direction) position. This reduces the angle between the front end 23 of the guide needle body 22 and the wire body 8 when the guide needle module 20 moves downward, preventing the force from concentrating at the corner of the guide needle 20, thereby improving the winding quality. It is worth noting that when the guide needle module 20 changes from swinging downward at the first angle θ (see Figure 8) to swinging upward at the second angle θ (see Figure 9), the guide needle body 22 first returns to a horizontal state (see Figure 7) and the front end 23 first retracts and then protrudes. Since the guide needle module 20 of the guide needle winding device 1 in this case can maintain a fixed horizontal position when swinging, there is no need to further move the frame 90 or the guide needle winding device 1 to compensate for the horizontal distance difference ΔX caused by the swing of the guide needle body 22, thus reducing operating costs and process time.

[0061] Referring to Figures 9, 11, and 15. In this embodiment, when the guide needle module 20 moves relative to the winding target electrode 91a along the lower horizontal displacement path p4, the front end 23 of the guide needle body 22 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, and the guide needle module 20 of the guide needle winding device 1 moves horizontally relative to the winding target electrode 91a. At this time, the rotation module 30 maintains the downward swing of the guide needle module 20 to the second angle θ (see Figure 9), and the guide module 40 drives the front end 23 of the guide needle body 22 to slide forward and protrude, maintaining a fixed lateral (i.e., X-axis direction) position. This allows the distance between the front end 23 and the winding target electrode 91a to be greatly shortened during the horizontal displacement of the guide needle module 20, and avoids impacting the lower flange 93b of the lower edge of the winding target electrode 91a. Since the longitudinal height of the front end 23 of the guide needle body 22 can be higher than the lower flange 93b when it is in the horizontal displacement path p4 at the lower end, the distance of the wire 8 falling to the winding target electrode 91a is effectively reduced, which helps to reduce the wire routing disorder and thus improve the winding quality.

[0062] Therefore, this invention utilizes the rotation module 30 and the guide module 40 to drive the guide needle body 22 to swing at an appropriate angle and maintain a fixed lateral displacement as it travels along the winding path P. This reduces the angle between the guide needle body 22 and the wire exit direction of the wire body 8, thereby reducing the tension stress concentration problem caused by the wire exit direction being too perpendicular to the guide needle body 22, and thus stabilizing the winding quality. It should be emphasized that the guide needle winding device 1 also has a swing angle compensation mechanism. Utilizing a purely mechanical structural design, it can automatically compensate for the lateral distance difference ΔX caused by the swing of the guide needle module 20, eliminating the need for algorithmic calculation of the compensation value. During elongation compensation, the guide needle module 20 only moves the guide needle body 22, greatly reducing the mass that needs to be moved and significantly increasing the swing angle speed, thus achieving extremely high winding speeds during winding operations. On the other hand, when the guide needle module 20 is horizontally displaced, the front end 23 of the guide needle body 22 can approach the winding target electrode 91a while avoiding the upper flange 93a and the lower flange 93b, greatly shortening the distance between the front end 23 and the winding target electrode 91, reducing the distance the wire 8 falls to the winding target electrode 91a, and further helping to reduce wire routing disorder. Of course, for winding operations with different tension wires, the swing angle of the guide needle body 22 can be adjusted according to actual application requirements, and is not limited to a fixed value. In other embodiments, the rotation module 30 and the guide module 40 can also control the front end 23 of the guide needle body 22 to freely change its swing angle relative to the longitudinal direction on the upward vertical displacement path p1, the upper horizontal displacement path p2, the downward vertical displacement path p3, and the lower horizontal displacement path p4, so as to respond to changes in tension wires and smoothly and efficiently wind the wire 8 onto each electrode 91 of the annular frame 90. Of course, this invention is not limited to this, and will not be elaborated further.

[0063] In summary, this invention provides a guide needle winding device with a swing angle compensation mechanism. This mechanism automatically compensates for the lateral horizontal displacement of the guide needle during longitudinal swing angles, maintaining a fixed lateral horizontal displacement without requiring movement of the entire device or additional servo shafts for compensation. This effectively increases the swing angle speed while reducing costs. The cam guide assembly and cam bearing assembly, combined with the sliding mechanism of the guide needle module, allow the guide needle body to automatically compensate for the lateral horizontal displacement during swing angles. This enables the swing-angle guide needle to swing up and down at extremely high speeds during winding while maintaining a fixed lateral horizontal displacement. Since the swing angle elongation compensation method can be constructed using a purely mechanical structure, the compensation value can be calculated without algorithms. Furthermore, the guide needle mechanism only moves the guide needle body during elongation compensation, significantly reducing the mass of the moving parts and greatly increasing the swing angle speed. Therefore, extremely high winding speeds can be achieved during winding operations. Moreover, the swing angle elongation compensation method of the swing angle compensation mechanism is a purely mechanical structure, eliminating the need for additional servo motor shafts to compensate for lateral horizontal displacement during winding operations, thus reducing costs. The sway angle compensation mechanism features a cam curve plate at the rear end of the sway angle guide needle body. This curve controls the extension / retraction of the guide needle body as the sway angle increases, ensuring the lateral position of the sway angle guide needle relative to the exit point remains constant during swaying, facilitating the winding process. Because of the sway angle compensation mechanism of the guide needle winding device, the front end of the guide needle body can sway to a suitable angle and maintain a fixed lateral horizontal displacement in conjunction with the winding path during the rising or falling displacement segment. This reduces the angle between the guide needle front end and the exit direction of the wire, preventing force concentration at the guide needle corner and thus improving winding quality. Furthermore, when the guide needle body is horizontally displaced relative to the electrode, the front end of the guide needle body can extend into the electrode. This significantly shortens the distance between the front end and the target electrode, reducing the distance the wire falls to the target electrode and further reducing wire routing disorder. For winding operations involving high-tension yarn, the oscillation module can control the guide pin body to oscillate downwards by, for example, 45 degrees on the upward vertical displacement path and the upper horizontal displacement path; and control the guide pin body to oscillate upwards by, for example, 45 degrees on the downward vertical displacement path and the lower horizontal displacement path, thereby reducing tension. Of course, regardless of the longitudinal oscillation angle of the guide pin body, the lateral position of the lead-out point can be maintained unchanged. Therefore, the guide pin winding device of this invention does not require an additional servo motor shaft to compensate for the offset horizontal displacement during winding operations, thus reducing operating costs and process time, and also reducing the distance the yarn falls to reduce yarn routing disorder. However, this invention is not limited to this.
