Abstract
Description
Technical Field
[0001] This invention relates to the field of curved coil winding, and in particular to a guide wheel mechanism with a steerable guide wheel. Background Technology
[0002] A coil typically refers to a loop of wire winding. Common applications include motors, inductors, transformers, and loop antennas. However, with the increasing number of applications, specific types of coils are needed to meet these requirements, such as curved coils, which are suitable for electronic devices with curved surfaces. Current technologies for winding such coils using wire have limitations. For example, Chinese patent CN202122867550.1 discloses a tooling for winding a two-dimensional curved coil with a transverse magnetic field, which includes a limiting ring, a central pressure plate, and a winding base. The central pressure plate and winding base are arranged from top to bottom. The shape of the winding base matches the shape of the coil to be wound. The central pressure plate is tightly fitted to the center of the winding base, and its shape matches the shape of the central cavity of the coil to be wound. This allows the wire to be wound to surround itself and conform to the shape of the winding base. The limiting ring is semi-circular, matching the shape of the winding base. The limiting ring is fixed above the central pressure plate and close to the winding base. Multiple limiting rings are parallel to each other and spaced apart. A gap is left between the limiting ring and the inner wall of the winding base for the wire to pass through during winding. This fixture can be connected to a winding machine. The wire is aligned with the inlet and inserted turn by turn. After winding, the limiting ring is removed, the coil is taken off, and the limiting ring is reinstalled for repeated production. This fixture enables the winding of curved coils, but it can result in uneven wire and unsmooth wire routing after winding. Especially when winding curved coils with square conductors, it is impossible to make one side of the square conductor completely fit against the winding base during the winding process, which leads to a decrease in winding quality and easy to produce defective parts. Summary of the Invention
[0003] In view of this, the present invention provides a guide wheel mechanism with a steerable guide wheel to solve the above problems.
[0004] A guide wheel mechanism with steerable guide wheels is disclosed for guiding at least one conductor. The guide wheel mechanism includes a drive unit, a steering rod disposed on one side of the drive unit, and at least two guide wheel assemblies rotatably mounted on the steering rod. The conductor is a square conductor. The two guide wheel assemblies are arranged at intervals along the length of the conductor. The conductor passes sequentially through the two guide wheel assemblies to ensure that the conductor between the two guide wheel assemblies does not tilt due to rotation of the guide wheel assemblies. Each guide wheel assembly includes at least one pivot shaft passing through the steering rod, a first collar sleeved on the pivot shaft, and a... The second ring is located on the rotating shaft and on one side of the first ring. The first ring has a first inclined surface on the side facing the second ring, and the second ring has a second inclined surface on the side facing the first ring. The first and second inclined surfaces are arranged opposite each other and form a V-shaped surface. After the driving device drives the steering rod and drives the guide wheel assembly on it to slowly rotate 90 degrees, the wire will rotate 90 degrees around the steering rod under the drive of the first and second rings, so that the side of the wire that is attached to the curved skeleton also rotates 90 degrees, thereby winding to form a curved coil.
[0005] Furthermore, a bearing is fitted onto one end of the rotating shaft near the steering rod, and the rotating shaft rotatably passes through the steering rod.
[0006] Furthermore, the first collar and the second collar abut against each other, and the first collar and the second collar are fixedly sleeved on the end of the rotating shaft.
[0007] Furthermore, the first and second rings can also be integrated as one piece, with a V-shaped concave surface opened on their circumferential outer wall.
[0008] Compared with the prior art, the guide wheel mechanism with steerable guide wheels provided by the present invention guides and limits the wire by means of two guide wheel assemblies spaced apart on one side of the driving device, and rotates the guide wheel assembly under the drive of the driving device, so that the wire rotates 90 degrees, thereby allowing the wire to fit completely against the curved skeleton, making the wire laying smooth and neat, and improving the winding quality.

[0009] Figure 1 This is a schematic diagram of the guide wheel mechanism with a steerable guide wheel provided by the present invention.
[0010] Figure 2 for Figure 1 A cross-sectional schematic diagram of a guide wheel mechanism with steerable guide wheels. Detailed Implementation
[0011] The following provides a more detailed description of specific embodiments of the present invention. It should be understood that the description of the embodiments of the present invention herein is not intended to limit the scope of protection of the present invention.
[0012] like Figure 1 The diagram shows a schematic representation of the guide wheel mechanism with steerable guide wheels provided by the present invention. The guide wheel mechanism with steerable guide wheels includes a drive device 10, a steering rod 20 disposed on one side of the drive device 10, and at least one guide wheel assembly 30 rotatably disposed on the steering rod 20. It is conceivable that the guide wheel mechanism with steerable guide wheels also includes other functional modules, such as a power module, a winding module, etc., which are technologies known to those skilled in the art and will not be described in detail here.
[0013] It should be noted that the guide wheel mechanism with steerable guide wheel is used to guide at least one wire 40, especially a square wire. Since the square wire has a flat side, when winding, one side of the square wire needs to be attached to the curved frame to form a curved coil.
[0014] Please see Figure 2 The drive device 10 is driven by the aforementioned power module. The output end of the drive device 10 is fixedly connected to the steering rod 20, thereby enabling the drive device 10 to drive the steering rod 20 to rotate, thus achieving guidance of the guide wheel assembly 30 at different angles.
[0015] The guide wheel assembly 30 includes at least one pivot 31 passing through the steering rod 20, a first collar 32 sleeved on the pivot 31, and a second collar 33 sleeved on the pivot 31 and located on one side of the first collar 32.
[0016] A bearing is fitted onto one end of the rotating shaft 31 near the steering rod 20, and the bearing is embedded in the steering rod 20, so that the rotating shaft 31 can rotatably pass through the steering rod 20.
[0017] The first collar 32 and the second collar 33 abut against each other, and the first collar 32 and the second collar 33 are fixedly sleeved on the end of the rotating shaft 31. This allows the first and second collars 32 and 33 to drive the rotating shaft 31 to rotate when the wire is fed, thereby preventing the first and second collars 32 and 33 from loosening when rotating around the rotating shaft 31 and affecting the distance between them. This ensures the smoothness of wire feeding and prevents the quality of winding from deteriorating.
[0018] In another embodiment, the first and second rings 32 and 33 are integral, and a V-shaped concave surface is formed on their circumferential outer wall, thus achieving the above-mentioned effect.
[0019] The first collar 32 has a first inclined surface 34 on the side facing the second collar 33, and the second collar 33 has a second inclined surface 35 on the side facing the first collar 32. The first and second inclined surfaces 34 and 35 are arranged opposite each other and form a V-shaped surface, so that the wire 40 can stably pass through the V-shaped surface. When the driving device 10 drives the steering rod 20 and drives the guide wheel assembly 30 thereon to rotate slowly by 90 degrees, the wire 40 will rotate 90 degrees around the steering rod 20 under the drive of the first and second collars 32 and 33. This causes the side of the wire 40 that is attached to the curved frame to also rotate 90 degrees, thereby winding to form a curved coil.
[0020] Preferably, there are two guide wheel assemblies 30. The two guide wheel assemblies 30 are arranged at intervals along the length of the steering rod 20. In this way, when the wire 40 passes through the two guide wheel assemblies 30 in sequence, it can be ensured that the wire 40 between the two guide wheel assemblies 30 will not tilt due to the rotation of the guide wheel assemblies 30, thereby ensuring the winding quality.
[0021] Compared with the prior art, the guide wheel mechanism with steerable guide wheels provided by the present invention guides and limits the wire 40 through two guide wheel assemblies 30 spaced apart on one side of the drive device 10. Under the drive of the drive device 10, the guide wheel assembly 30 rotates, causing the wire 40 to rotate 90 degrees, so that the wire 40 can completely fit on the curved skeleton, making the wire 40 run smoothly and neatly, and improving the winding quality.
[0022] The above are merely preferred embodiments of the present invention and are not intended to limit the scope of protection of the present invention. Any modifications, equivalent substitutions or improvements within the spirit of the present invention are covered within the scope of the claims of the present invention.
