Technical field

The present disclosure relates generally to the field of coil winding, and in particular to a planar coil winding device.

Background technique

Coil is a common circuit component that uses the principle of electromagnetic induction to work. Among them, the winding process of the coil has a great impact on the performance of the coil and will affect the application range of the coil. With the continuous development of electronic and electrical technology, coil winding technology has gradually attracted people's attention.

Patent Document 1 discloses an alcohol-soluble automatic winding method: the enameled wire first passes through an alcohol filter and is then fixed to a winding mechanism. The winding machine is started, and the winding mechanism winds the enameled wire into a coil. Finally, a hot air mechanism is used Dry the coil and complete the winding of the coil.

Patent Document 2 discloses a linear and planar motor coil winding device for winding flat or round enameled wires. The linear and planar motor coil winding device also includes an alcohol tank containing alcohol. The enameled wire passes through the alcohol tank and is then transferred to the winding mold to be wound into a coil.

In the above coil winding technology, the cables used for winding the coil are all enameled wires with enameled layers. During the winding process, the enameled wire first passes through a container containing alcohol. The enameled layer of the enameled wire softens and becomes sticky after being soaked in alcohol. The enameled wire with the softened enameled layer is sent to the winding device and wound into a coil. Finally, the softened and sticky enameled layer bonds the enameled wires in the coil together. After the coil is wound, the alcohol evaporates to re-solidify the enameled layer, so that the coil is solidified and shaped.

However, the enameled coating of the enameled wire used in the above-mentioned coil winding technology is usually not biocompatible, and the alcohol used to soften the enameled coating has certain biological toxicity. Coils wound by the above-mentioned coil winding technology are usually not biocompatible and are not suitable for use in the field of biomaterials.

FIG. 5 is a schematic structural diagram showing the winding mechanism 10 in the winding device 1 shown in FIG. 1 . FIG. 6 is another structural schematic diagram showing the winding mechanism 10 in the winding device 1 shown in FIG. 1 . FIG. 7 is a schematic diagram showing the connection between the bobbin 11 and the wire core 12 in the winding device 1 shown in FIG. 1 . FIG. 8 is a schematic diagram showing the separation of the bobbin 11 and the wire core 12 in the winding device 1 shown in FIG. 7 . The winding mechanism 10 is described in detail below with reference to FIGS. 5 , 6 , 7 and 8 .

In some examples, the winding mechanism 10 may have a winding shaft 11 for winding the metal wire 2. In some examples, the winding shaft 11 may be roughly in the shape of an elongated cylinder, and may rotate along its own circumferential direction with its own axis as the central axis (see FIGS. 5 and 6 ). When the winding shaft 11 rotates, the metal wire 2 may be driven to be wound into a coil 3. In this case, the guide path L may be arranged along the circumference of the winding shaft 11, so that the metal wire 2 may be wound around the winding shaft 11 along the circumference of the winding shaft 11 to form a coil 3.

Additionally, in some examples, the reel 11 may include two cylinders, namely a first cylinder 11a and a second cylinder 11b (see FIG. 7). In some examples, the bottom surface diameter of the first cylinder 11a may be larger than the bottom surface diameter of the second cylinder 11b. In some examples, the bottom surfaces of the first cylinder 11 a and the second cylinder 11 b are coupled to each other to form the reel 11 . In some examples, the first cylinder 11a and the second cylinder 11b may be coupled in a coaxial manner. In this case, the guide path L may be provided on the side of the first cylinder 11a along the circumferential direction of the first cylinder 11a, and the metal wire 2 may be wound around the side of the first cylinder 11a along the guide path L, to form coil 3.

In addition, in some examples, an oblate cylinder 11c may be provided at the connection between the first cylinder 11a and the second cylinder 11b (see FIG. 7 ). In some examples, the base radius of the oblate cylinder 11c may be slightly smaller than the base radius of the first cylinder 11a and the second cylinder 11b, and the two bases of the oblate cylinder 11c are respectively connected to the base of the first cylinder 11a and the base of the second cylinder 11b. In some examples, the oblate cylinder 11c may be connected to the first cylinder 11a and the second cylinder 11b in a coaxial manner.

In some examples, an end of the first cylinder 11a away from the second cylinder 11b may also be provided with a groove 11d for accommodating the wire core 12 (described later).

In some examples, the second cylinder 11 b may be used to couple the spool 11 and the fixed frame 30 . In some examples, a protrusion 11e (described later) for coupling the driving mechanism 40 may also be provided at the end of the second cylinder 11b of the reel 11 away from the first cylinder 11a.

The example of the present disclosure is not limited thereto, and there may be a plurality of reels 11 in the reel mechanism 10 . Multiple reels 11 can rotate simultaneously. In this case, the metal wire 2 can also be a plurality of metal wires, and the plurality of metal wires can be driven by a plurality of winding shafts 11 to be wound into the coil 3 . Simultaneous rotation of multiple winding shafts 11 enables simultaneous winding of multiple coils 3 and improves the winding efficiency of coils 3 . In some examples, the reel 11 may also be generally in the shape of a prism, a frustum, a cone, a pyramid, etc.

In some examples, the winding mechanism 10 may further include a wire core 12 coupled with the winding shaft 11 (see FIG. 5 ).

In addition, in some examples, the wire core 12 may be linked with the reel 11 . The metal wire 2 can be wound around the core 12 to form a coil 3 (see Figures 3 and 4). In this case, the wire core 12 can be rotated by rotating the bobbin 11, and the metal wire 2 can be wound around the wire core 12. In this case, the guide path L can be provided at the wire core 12 . When the wire core 12 rotates, the wire core 12 can drive the metal wire 2 along the guide path L to be wound into the coil 3 at the wire core 12 .

In addition, in some examples, the wire core 12 may be in the shape of an elongated rectangular parallelepiped (see FIG. 8 ), that is, the wire core 12 may have a smaller thickness and a larger length. In some examples, the wire core 12 may be received in the groove 11d so as to be able to follow the rotation of the spool 11 .

In addition, in some examples, the groove 11d may be in the shape of an oblate rectangular parallelepiped that matches the wire core 12 (see FIG. 8). That is to say, when the wire core 12 is placed in the groove 11d, the wire core 12 can be The grooves 11d are coaxial. In some examples, the cross-section of the groove 11d along its depth direction is slightly larger than the cross-section of the wire core 12 along its axial direction. In some examples, the depth direction of the groove 11d may be parallel to the axial direction of the first cylinder 11a. In some examples, the center point of the cross-section of the groove 11d along its depth direction may be located on the central axis of the first cylinder 11a. In this case, after the wire core 12 is placed in the groove 11d, the wire core 12 may be coaxial with the first cylinder 11a.

In some examples, the wire core 12 can be removed from the groove 11 d to achieve a detachable connection between the wire core 12 and the winding shaft 11 (see FIG. 8 ).

In some examples, after the core 12 is placed in the groove 11d, a small portion of the core 12 may be exposed from the groove 11d (see FIG. 5 ), that is, the length of the core 12 may be greater than the depth of the groove 11d. At this time, the guide path L may be set at the exposed portion of the core 12, and the metal wire 2 may be wound around the exposed portion of the core 12 along the guide path L to form the coil 3.

In some examples, the exposed portion of the wire core 12 may also be provided with a wire trough (not shown) for fixing the metal wire 2 , and one end of the metal wire 2 is inserted into the wire trough to fix the metal wire 2 to the wire core 12 . In some examples, the wire groove of the wire core 12 is located on the guide path L. When the wire core 12 rotates, since one end of the metal wire 2 is fixed at the wire core 12 , the metal wire 2 can be wound into the coil 3 due to the rotation of the wire core 12 .

In some examples, after the winding of the coil 3 is completed, the coil 3 can be removed from the bobbin 11 together with the wire core 12 while the coil 3 is wound around the wire core 12 .

In some examples, the reel 11 may also have an elastic component (not shown). In some examples, the elastic component can be placed in the reel 11 and fit with the wire core 12 placed in the groove 11d to provide a certain elastic force for the wire core 12 to slide in the groove 11d.

In some examples, the elastic component may be a column spring, the axis of which may be coincident with the axis of the cylinder of the reel 11, and one end of which may be in fit with the wire core 12 placed in the groove 11d. In this case, when the wire core 12 slides in the groove 11d, the column spring will be squeezed, thereby restricting the sliding of the wire core 12 in the groove 11d.

Examples of the present disclosure are not limited thereto, and the elastic component in the reel 11 may be a leaf spring, a torsion spring, a coil spring, or the like. In some examples, the elastic component may also be parts made of elastic materials such as rubber, plastic, rubber, etc. In some examples, the elastic component may be an elastic cylinder made of rubber.

FIG. 18 is a top view showing the coating mechanism 20 in the winding device 1 shown in FIG. 1 . The coating mechanism 20 is described in detail below with reference to FIGS. 15 , 16 , 17 and 18 .

In some examples, coating mechanism 20 may have a container 21 for holding a biocompatible adhesive (see Figure 15). At this time, the guide path L can be set in the container 21 , and the metal wire 2 can pass through the adhesive in the container 21 along the guide path L, and then be sent to the winding mechanism 10 to be wound into the coil 3 .

Additionally, in some examples, container 21 may include an outer wall 211 and a cavity 212 (see Figure 15). In some examples, the outer wall 211 may be generally in the shape of a cuboid, and a cylindrical cavity 212 is formed in the outer wall 211 .

In some examples, the outer wall 211 may be in the shape of a cube, a cylinder, a prism, etc. The cavity 212 may be in the shape of a cube, a cuboid, a prism, a truncated cone, a cone, etc.

In some examples, when using the winding device 1 to wind the coil 3, the metal wire 2 can first pass through the biocompatible adhesive in the container 21, so that the biocompatible adhesive can be coated. Covered on metal wire 2. Then, the metal wire 2 coated with a biocompatible adhesive can be fixed on the spool 11 . Next, the bobbin 11 is rotated to wind the metal wire 2 coated with the biocompatible adhesive into a coil 3 . Since the metal wire 2 is coated with a biocompatible adhesive before being wound into the coil 3, the completed coil 3 will also be covered with a biocompatible adhesive, thereby making the coil 3 has a biocompatible outer layer, thereby improving the biocompatibility of the coil 3 .

In addition, in some examples, the notch 224a of the outer wall 224 and the notch 211b of the outer wall 211 may be the same notch, that is, the outer wall 224 and the outer wall 211 share a notch and are connected together. At this time, the guide path L may pass through the crimping part 22 . The guide path L can guide the metal wire 2 to penetrate into the wire pressing part 22 from the notch 224b, and pass between the first pressure piece 222 and the second pressure piece 223, and then pass out of the notch 224a (also the notch 211b). The part 22 enters the container 21, and then passes through the adhesive in the cavity 212 and exits from the through hole 211a.

In some examples, when winding the coil 3, the metal wire 2 can be passed through the notch 224b into the wire pressing portion 22, and after passing between the first pressure piece 222 and the second pressure piece 223, from the notch 224a (also The notch 211b) passes through the crimping portion 22 and enters the container 21 . After the metal wire 2 enters the container 21 , it passes through the adhesive in the cavity 212 , passes out of the through hole 211 a , and enters the winding mechanism 10 to be wound into the coil 3 . In this process, the pressure block 221 is pressed against the first pressure piece 222 and the second pressure piece 223, so that the metal wire 2 can be clamped between the first pressure piece 222 and the second pressure piece 223, thereby realizing the metal wire clamping. The sliding of 2 causes damping.

Examples of the present disclosure are not limited thereto. The first pressure piece 222 and the second pressure piece 223 may be other sheet-shaped objects, such as rubber sheets, plastic sheets, metal sheets, etc. In some examples, the first pressure piece 222 and the second pressure piece 223 may be a soft block-shaped object having a channel for the metal wire 2 to pass through. The soft block object is squeezed by the pressure block 221 to cause deformation, thereby deforming the channel, thereby exerting pressure on the metal wire 2 . In some examples, the first pressure piece 222 and the second pressure piece 223 can also be pulleys with two connecting contours, and the metal wire 2 passes through the connecting contours of the two pulleys, thereby clamping the metal wire 2 .
