Description

Winding device for planar coil

The present application is a divisional application of patent application of a winding device having a biocompatible coil, the application number of which is 201911330370.0, and the application number of which is 2019, 12 and 20.

Technical Field

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

Background

A coil is a common circuit element, which is a device that operates using the principle of electromagnetic induction. The winding process of the coil has a great influence on the performance of the coil, and can influence the application range of the coil. With the continuous development of electronic and electric technologies, coil winding technology is attracting attention.

Patent document 1 discloses an alcohol-soluble automatic winding method: the enameled wire passes through the alcohol filter and is then fixed on the winding mechanism, the winding machine is started, the winding mechanism winds the enameled wire into a coil, and finally, the coil is dried by the hot air mechanism, so that the winding of the coil is completed.

Patent document 2 discloses a linear and planar motor coil winding device for winding a flat or circular enamel wire. The linear and planar motor coil winding device further comprises an alcohol tank for containing alcohol, and the enameled wire passes through the alcohol tank and then is transmitted to the winding mould to be wound into a coil.

In the above-mentioned coil winding technique, the wires used for winding the coils are enameled wires having a varnish layer. In the winding process, the enameled wire firstly passes through a container filled with alcohol, the enamelled layer of the enameled wire is softened and generates viscosity after being soaked in alcohol, the enameled wire with the softened enamelled layer is sent into a winding device to be wound into a coil, and finally, the enameled wire in the coil is bonded together by the softened enamelled layer with viscosity. After the coil is wound, the enamelled layer is cured again through alcohol volatilization so as to cure and shape the coil.

However, the enamel coating of the enamel wire used in the above-mentioned coil winding technique is generally not biocompatible, and alcohol for softening the enamel coating is more particularly toxic to some extent. The coil wound by the coil winding technology is generally not biocompatible and is not suitable for the field of biological materials.

Detailed Description

All references cited in this disclosure are incorporated by reference in their entirety as if fully set forth. Unless defined otherwise, technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this disclosure belongs. A general guide for many of the terms used in this disclosure is provided to those skilled in the art. Those skilled in the art will recognize many methods and materials similar or equivalent to those described in the present disclosure that can be used in the practice of the present disclosure. Indeed, the present disclosure is in no way limited to the described methods and materials.

The present disclosure relates to a winding device that can prepare a coil having biocompatibility that can be used as, for example, a circuit element by coating a surface of, for example, a wire with an adhesive having biocompatibility, and winding the wire coated with the adhesive having biocompatibility. The winding device according to the present disclosure will be described in detail below with reference to the accompanying drawings.

Fig. 1 is a schematic perspective view showing a winding device 1 having a biocompatible coil 3 according to the present disclosure. Fig. 2 is an exploded perspective view showing the winding device 1 shown in fig. 1. Fig. 3 is a schematic view showing the winding device 1 shown in fig. 1 in a wound state. Fig. 4 is a schematic perspective view, cut away, taken along section line AA', showing the winding device 1 shown in fig. 3 in a wound state. The winding device 1 is described in detail below in connection with fig. 1, 2, 3 and 4.

In the present embodiment, as shown in fig. 1 and 2, the winding device 1 may include a winding mechanism 10 and a coating mechanism 20. Wherein, as shown in fig. 3 and 4, the winding mechanism 10 may be used to wind the wire 2, and the coating mechanism 20 may be used to apply an adhesive having biocompatibility on the wire 2. In addition, a guide path L is formed in the winding device 1, and the guide path L allows the wire 2 to pass through the adhesive and be wound on the winding mechanism 10 to form the coil 3.

In winding the coil 3 using the winding device 1 according to the present disclosure, the wire 2 may be first passed through an adhesive having biocompatibility and then wound into the coil 3 at the winding mechanism 10. Thus, the coil 3 wound by the winding mechanism 10 is covered with the biocompatible adhesive, and the biocompatibility of the coil 3 can be improved.

Fig. 5 is a schematic diagram showing a structure of the winding mechanism 10 in the winding device 1 shown in fig. 1. Fig. 6 is another schematic structural view showing the winding mechanism 10 in the winding device 1 shown in fig. 1. Fig. 7 is a schematic view showing the coupling of the wire reel 11 with the wire core 12 in the winding apparatus 1 shown in fig. 1. Fig. 8 is a schematic view showing the separation of the wire reel 11 from the wire core 12 in the winding apparatus 1 shown in fig. 7. The winding mechanism 10 is described in detail below with reference to fig. 5, 6, 7, and 8.

In some examples, the winding mechanism 10 may have a spool 11 for winding the wire 2. In some examples, the spool 11 may have a substantially long cylindrical shape, and may rotate in its circumferential direction about its axis as a central axis (see fig. 5 and 6). When the spool 11 rotates, the wire 2 is wound into the coil 3. In this case, the guide path L may be provided along the circumferential direction of the wire spool 11 so that the wire 2 may be wound around the wire spool 11 along the circumferential direction of the wire spool 11 to form the coil 3.

In addition, in some examples, the spool 11 may include two cylinders, i.e., 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 greater than the bottom surface diameter of the second cylinder 11 b. In some examples, the bottom surfaces of the first cylinder 11a and the second cylinder 11b are coupled to each other in a fitting manner to form the spool 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 at a side of the first cylinder 11a in the circumferential direction of the first cylinder 11a, and the wire 2 may be wound at the side of the first cylinder 11a along the guide path L to form the coil 3.

In addition, in some examples, an oblate cylinder 11c (see fig. 7) may also be provided at the junction of the first cylinder 11a and the second cylinder 11 b. In some examples, the bottom radius of the flat cylinder 11c may be slightly smaller than the bottom radii of the first cylinder 11a and the second cylinder 11b, and the two bottom surfaces of the flat cylinder 11c are coupled with the bottom surface of the first cylinder 11a and the bottom surface of the second cylinder 11b, respectively. In some examples, the oblate cylinder 11c and the first and second cylinders 11a, 11b may be coupled in a coaxial manner.

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

In some examples, a second cylinder 11b may be used to couple the spool 11 and the mount 30. In some examples, a protrusion 11e (described later) for coupling the driving mechanism 40 may be further provided at an end of the second cylinder 11b of the wire spool 11 remote from the first cylinder 11 a.

Examples of the present disclosure are not limited thereto, and the winding mechanism 10 may have a plurality of winding shafts 11 therein. The plurality of bobbins 11 can be rotated at the same time. In this case, the wire 2 may be a plurality of wires, and the plurality of wires may be wound around the coil 3 by a plurality of bobbins 11, respectively. The simultaneous rotation of the plurality of bobbins 11 enables the simultaneous winding of the plurality of coils 3, and improves the winding efficiency of the coils 3. In some examples, the spool 11 may also be generally prismatic in shape, frustoconical in shape, conical in shape, pyramidal in shape, or the like.

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

Additionally, in some examples, the wire core 12 may be coupled with the wire spool 11. The wire 2 may be wound into a coil 3 at the wire core 12 (see fig. 3 and 4). In this case, the wire core 12 can be rotated by rotating the wire reel 11, so that the wire 2 can be wound with the wire core 12. In this case, the guide path L may be provided at the wire core 12, and when the wire core 12 rotates, the wire core 12 may drive the wire 2 to be wound into the coil 3 at the wire core 12 along the guide path L.

In addition, in some examples, the wire core 12 may have a prolate cuboid shape (see fig. 8), i.e., 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 wire spool 11.

In addition, in some examples, the groove 11d may have an oblong rectangular parallelepiped shape (see fig. 8) that mates with the wire core 12, that is, the wire core 12 may be coaxial with the groove 11d when the wire core 12 is placed into the groove 11 d. In some examples, the cross-section of the groove 11d in its depth direction is slightly larger than the cross-section of the wire core 12 in its axial direction. In some examples, the depth direction of the groove 11d may be parallel to the axial direction of the first cylinder 11 a. In some examples, the center point of the cross section of the groove 11d in the depth direction thereof may be located on the center axis of the first cylinder 11 a. In this case, when the wire core 12 is put into the groove 11d, the wire core 12 may be coaxial with the first cylinder 11 a.

In some examples, the wire core 12 may be removed from the recess 11d to enable the wire core 12 to be detachably connected with the wire spool 11 (see fig. 8).

In some examples, after the core 12 is placed in the groove 11d, a small portion thereof 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 11 d. At this time, the guide path L may be provided at an 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 slot (not shown) for securing the wire 2, one end of the wire 2 being inserted into the wire slot to secure the wire 2 at the wire core 12. In some examples, the wire chase of the wire core 12 is located on the guide path L. When the wire core 12 rotates, since one end of the wire 2 is fixed at the wire core 12, the wire 2 can be wound into the coil 3 by the rotation of the wire core 12.

In some examples, after the winding of the coil 3 is completed, the coil 3 may be removed from the wire bobbin 11 together with the wire core 12 while maintaining a state in which the coil 3 is wound at the wire core 12.

In some examples, the spool 11 may also have a resilient member (not shown) therein. In some examples, an elastic member may be placed in the wire spool 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 11 d.

In some examples, the elastic member may be a cylindrical spring whose axis may coincide with the axis of the cylinder of the wire-winding shaft 11 and whose one end is fitted with the wire core 12 placed in the groove 11 d. In this case, the column spring is pressed when the wire core 12 slides in the groove 11d, thereby restricting the sliding of the wire core 12 in the groove 11 d.

Examples of the present disclosure are not limited thereto, and the elastic member in the wire spool 11 may be a leaf spring, a torsion spring, a coil spring, or the like. In some examples, the elastic member may also be some piece made of an elastic material such as rubber, plastic, rubber, or the like. In some examples, the elastic member may be a resilient cylinder made of rubber.

Fig. 9 is a schematic view showing the cooperation of the first holding member 13, the second holding member 14, the wire core 12, and the wire spool 11 in the winding apparatus 1 shown in fig. 1. The first clamping member 13 and the second clamping member 14 are described in detail below in connection with fig. 9.

In some examples, the winding mechanism 10 may have a first clamp 13 and a second clamp 14 disposed opposite each other (see fig. 5 and 6). In some examples, a space 17 (see fig. 9) for clamping the wire 2 and the coil 3 may be formed between the first clamping member 13 and the second clamping member 14. In this case, the wire 2 and the coil 3 can be clamped between the first clamp 13 and the second clamp 14, and the wire 2 is wound into the coil 3 under the guidance of the first clamp 13 and the second clamp 14, so that the wire 2 can be stably guided and wound into the coil 3 in the winding mechanism 10.

At this time, the guide path L may be provided between the first clamp 13 and the second clamp 14, the wire 2 is clamped between the first clamp 13 and the second clamp 14, and the coil 3 is wound under the guide of the first clamp 13 and the second clamp 14.

Additionally, in some examples, the first clamp 13 may be in the shape of a flat cylinder, and the second clamp 14 may also be in the shape of a generally flat cylinder. In some examples, the bottom surface diameter of the first clamp 13 may be equal to or slightly greater than or slightly less than the bottom surface radius of the second clamp 14. In some examples, the first clamping member 13 is arranged opposite the second clamping member 14, i.e. the first clamping member 13 and the second clamping member 14 may be arranged coaxially such that the circular bottom surfaces of the two flat cylinders are opposite and a space 17 for clamping the wire 2 and the coil 3 is formed between the two opposite circular bottom surfaces. In some examples, the width of the space 17 may be equal to or slightly greater than the diameter of the wire 2. At this time, the guide path L may be provided at the interval 17, and the wire 2 may be wound into the coil 3 while being guided by the first clamp 13 and the second clamp 14 by the interval 17 between the first clamp 13 and the second clamp 14.

Additionally, in some examples, the first clamp 13 may have a through slot (not shown). In some examples, the wire core 12 may extend through the through slot to extend through the first clamp 13. In other examples, the core 12 may extend through the first clamping member 13 and be exposed from the through groove to form the exposed portion 12a. In some examples, the exposed portion 12a may be formed in the space 17 (see fig. 9). In some examples, the length of the exposed portion 12a may be equal to or slightly less than the width of the space 17. At this time, the guide path L may be provided at the exposed portion 12a, and the wire 2 may be wound into the coil 3 at the exposed portion 12a.

In some examples, the through groove of the first clamping member 13 may have a rectangular parallelepiped shape that mates with the wire core 12. The axis of the through slot may coincide with the axis of the spool 11. In some examples, the axis of the wire core 12 may be perpendicular to the bottom surface of the first clamp 13.

Examples of the present disclosure are not limited thereto, and the first clamping member 13 may also have a prolate square body, a truncated cone body, or the like. In some examples, the number of grooves 11d through which the wire core 12 may pass may be plural. In some examples, the surface of the first clamp 13 may also be provided with a texture that facilitates guiding the winding of the wire 2. In some examples, the first clamp 13 may also have a structure that is cooperatively coupled with the spool 11, which is detachably connected with the spool 11.

In some examples, a magnet or other fixing portion made of a material having adhesive or suction may be further provided on the first clamping member 13, for fixing the first clamping member 13 to the spool 11.

Fig. 10 is a schematic view showing the winding device 1 of fig. 1 in a state in which the auxiliary winding shaft 15 is separated from the second holder 14. Fig. 11 is another schematic view showing the state in which the auxiliary winding shaft 15 is separated from the second holder 14 in the winding device 1 shown in fig. 1. The auxiliary winding shaft 15 is described in detail below with reference to fig. 10 and 11.

In some examples, the winding mechanism 10 may further include an auxiliary spool 15 (see fig. 5 and 6) that is independent of the spool 11. In some examples, the second clamp 14 may be coupled with the auxiliary spool 15 and the first clamp 13 may be coupled with the spool 11. In some examples, the second clamp 14 may be coupled coaxially with the auxiliary spool 15 and the first clamp 13 may be coupled coaxially with the spool 11. In this case, the first clamp 13 and the second clamp 14 can be fixed to the wire spool 11 and the auxiliary wire spool 15, respectively, and the space 17 can be formed between the wire spool 11 and the auxiliary wire spool 15, so that the wire 2 can be wound into the coil 3 between the wire spool 11 and the auxiliary wire spool 15.

In addition, in some examples, the auxiliary wire spool 15 may be disposed opposite the wire spool 11, and the central axis of the auxiliary wire spool 15 is collinear with the central axis of the wire spool 11. In some examples, the auxiliary spool 15 may include an elongated cylinder 15a and an oblate cylinder 15b. The long cylinder 15a is coupled with the circular bottom surface of the flat cylinder 15b to form the auxiliary wire spool 15. In some examples, the long cylinder 15a is coaxially coupled with the flat cylinder 15b.

Additionally, in some examples, the second clamp 14 may include three cylinders. The three cylinders are stacked one on top of the other to form the second clamp 14. In some examples, the three cylinders may be cylinders 14a, 14b, and 14c in that order. The radii of the circular bottom surfaces of the three flat cylinders, i.e., flat cylinder 14a, flat cylinder 14b, and flat cylinder 14c, decrease in sequence. In some examples, the cylinders 14a, 14b and 14c are stacked in a coaxial fashion. In some examples, the bottom surface of the flat cylinder 14a is opposite the bottom surface of the first clamp 13, and the flat cylinder 14c is coupled with the auxiliary wire spool 15.

In addition, in some examples, the long cylinder 15a and the flat cylinder 15b may be cylinders hollowed out internally. In some examples, the flat cylinder 14c is inserted into the hollowed flat cylinder 15b, so that the second clamping member 14 can be fixed to one end of the auxiliary winding shaft 15 (see fig. 10 and 11). In some examples, the hollowed-out portion of the oblate cylinder 15b is the same shape as the oblate cylinder 14c. In some examples, the hollowed-out portion of the oblate cylinder 15b has a cross-sectional diameter equal to or slightly greater than the diameter of the bottom surface of the oblate cylinder 14c. In some examples, the hollowed-out portion of the oblate cylinder 15b has a depth equal to or slightly greater than the length of the oblate cylinder 14c.

In some examples, the oblate cylinder 14c of the second clamp 14 may be a torus. In some examples, the oblate cylinder 14a of the second clamp 14 may be a truncated cone with a rounded bottom surface of smaller radius opposite the first clamp 13.

Examples of the present disclosure are not limited thereto, and the shape of the auxiliary winding shaft 15 may be a rectangular parallelepiped, a prism, a truncated cone, or the like. In some examples, the connection of the auxiliary reel 15 to the second clamping member 14 may be an adhesive connection, a mechanical structure-fitting connection, or a connection using the attractive force of a magnet, for example. In some examples, the auxiliary spools 15 may be plural and may have plural second clips 14 that mate with respective auxiliary spools 15.

The sizing sleeve 16 is described in detail below in connection with fig. 12 and 13.

In some examples, the winding mechanism 10 may also include a sizing sleeve 16 (see fig. 5 and 6). In some examples, the sizing sleeve 16 may cooperate with the first clamp 13 and the second clamp 14, the first clamp 13 and the second clamp 14 being embedded in the sizing sleeve 16. In this case, the state that the wire 2 and the coil 3 are clamped in the first clamping piece 13 and the second clamping piece 14 is maintained, and the first clamping piece 13 and the second clamping piece 14 are embedded in the molding sleeve 16, so that the first clamping piece 13 and the second clamping piece 14 can be better fixed to better maintain the shape of the coil 3.

In addition, in some examples, the setting sleeve 16 may be integrally formed of a hollow cylinder 16a and a circular ring 16b, the bottom surface inner diameter of the hollow cylinder 16a is the same as the bottom surface outer diameter of the circular ring 16b, the circular ring 16b is provided at the bottom surface of the hollow cylinder 16a, and the outer circumference of the circular ring 16b is integrally formed with the circumferential outer wall of the hollow cylinder 16a (see fig. 12). In other examples, the sizing sleeve 16 may also be integrally formed from a hollow sleeve 16a and a ring 16b that mates with the hollow sleeve 16 a.

In addition, in some examples, the first clamp 13 and the second clamp 14 may be sized to match the inside diameter of the bottom circular shape of the hollow cylinder 16a, thereby enabling the first clamp 13 and the second clamp 14 to be embedded within the hollow cylinder 16a (see fig. 13).

In some examples, the inner radius of the annular ring 16b may be slightly larger than the radius of the bottom surface circle of the auxiliary wire spool 15, thereby enabling the auxiliary wire spool 15 to pass through the sizing sleeve 16 to fit the sizing sleeve 16 over the auxiliary wire spool 15.

In addition, in some examples, the sizing sleeve 16 may be sleeved on the auxiliary winding shaft 15, and the end of the sizing sleeve 16 without the circular ring may face the direction of the first clamping member 13 and the second clamping member 14 to accommodate the first clamping member 13 and the second clamping member 14.

Additionally, in some examples, the inner surface of the non-circular end of the sizing sleeve 16 may be provided with anti-slip stripes. In some examples, the inner surface of the non-circular end of the sizing sleeve 16 may be threaded (see fig. 13). In some examples, the first clamping member 13 and the second clamping member 14 may be stably embedded in the setting sleeve 16 by the anti-slip stripes or threads.

In some examples, after the coil 3 is wound, the coil 3, the core 12, the first clamping member 13, and the second clamping member 14 may be embedded together in the molding sleeve 16. In this case, the coil 3 may be fixed after the completion of winding of the coil 3, maintaining the shape of the coil 3. In other examples, after the coil 3 is wound, the coil 3, the first clamping member 13, and the second clamping member 14 may be embedded together in the molding sleeve 16.

In some examples, after the coil 3 is wound, the coil 3 may be cured while the coil 3, the core 12, the first clamping member 13, and the second clamping member 14 are together embedded in the molding sleeve 16. In this case, the shape of the coil 3 can be maintained during the curing of the coil 3.

In some examples, the curing treatment may be selected from at least one of self-drying curing, oven drying curing, cooling curing, heat curing. In this case, different curing modes can be selected according to the adhesive to obtain a better curing effect.

Examples of the present disclosure are not limited thereto, and mechanical structures cooperating with the first clamping member 13 and the second clamping member 14 or inner pads made of soft materials such as rubber, plastic, etc. may be further provided in the setting sleeve 16 to enable the setting sleeve 16 to more stably and properly receive the first clamping member 13 and the second clamping member 14.

In some examples, the sizing sleeve 16 may also be designed as an openable ring structure. When the coil 3 is wound, the sizing sleeve 16 can be opened so as to be separated from the auxiliary winding shaft 15, and after the winding of the coil 3 is completed, the opened sizing sleeve 16 can be directly sleeved on the first clamping piece 13 and the second clamping piece 14 to be closed, so that the first clamping piece 13 and the second clamping piece 14 are sleeved in the sizing sleeve.

Fig. 14 is a bottom view showing the second clamp 14 in the winding device 1 shown in fig. 1.

In some examples, the second clamp 14 may also have an aperture 141 (see fig. 14) disposed along the length of the spool 11. In this case, the adhesive can be injected through the hole 141 into the wire 2 and the coil 3 sandwiched between the first clamp 13 and the second clamp 14, so that the wire 2 and the coil 3 are more sufficiently covered with the adhesive.

In addition, in some examples, after the winding of the coil 3 is completed, an adhesive may be injected from the opening 141 between the first clamp 13 and the second clamp 14. In this case, the adhesive can be applied to the coil 3 again so that the coil 3 is more sufficiently coated with the adhesive.

Examples of the present disclosure are not limited thereto, and the opening hole 141 may be provided in a structure that can be opened and closed to control the opening and closing of the opening hole 141 as needed, so that the adhesive is better stored between the first clamping member 13 and the second clamping member 14. In addition, the opening 141 may be provided in plurality. The openings 141 may be provided at various positions of the second clamp 14, so that the adhesive may be injected into the coil 3 from various orientations, so that the coil 3 is sufficiently covered with the adhesive.

Fig. 15 is a perspective view showing the coating mechanism 20 in the winding device 1 shown in fig. 1. Fig. 16 is a rear perspective view showing the coating mechanism 20 in the winding device 1 shown in fig. 1. Fig. 17 is a schematic perspective view showing the coating mechanism 20 in the winding device 1 shown in fig. 16, cut away along the section line BB'. Fig. 18 is a plan view showing the coating mechanism 20 in the winding device 1 shown in fig. 1. The coating mechanism 20 is described in detail below in conjunction with fig. 15, 16, 17, and 18.

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

Additionally, in some examples, the container 21 may include an outer wall 211 and a cavity 212 (see fig. 15). In some examples, the outer wall 211 may be generally rectangular parallelepiped in shape, with a cavity 212 formed in the outer wall 211 that is cylindrical in shape. The cavity 212 may be used to contain an adhesive that is biocompatible. In some examples, the cavity 212 may be a cylindrical recess formed in the outer wall 211, and the opening of the recess 11d is formed in the upper surface of the outer wall 211.

Examples of the present disclosure are not limited thereto, and the number of the containers 21 may be plural. When the plurality of wires 2 are wound, the plurality of wires 2 may pass through the corresponding containers 21, respectively. In some examples, the outer wall 211 may be in the shape of a cube, cylinder, prism, or the like. The cavity 212 may be square, rectangular, prismatic, truncated cone, etc.

In some examples, when winding the coil 3 using the winding device 1, the wire 2 may be first passed through the biocompatible adhesive in the container 21 so that the biocompatible adhesive is coated on the wire 2. Then, the wire 2 coated with an adhesive having biocompatibility may be fixed on the wire reel 11. Next, the wire reel 11 is rotated, and the wire 2 coated with the adhesive having biocompatibility is wound into the coil 3. Since the metal wire 2 is coated with the biocompatible adhesive before being wound into the coil 3, the wound coil 3 is also coated with the biocompatible adhesive, so that the coil 3 has a biocompatible outer layer, thereby improving the biocompatibility of the coil 3.

In some examples, the outer wall 211 may have a guide portion for guiding the wire 2 such that the wire 2 is impregnated with an adhesive. In this case, the wire 2 is better guided through the container 21 and the biocompatible adhesive is better applied to the wire 2.

In addition, in some examples, the guide portion may include a through hole 211a penetrating the outer wall 211 and a notch 211b formed in the outer wall 211 opposite to the through hole 211a (see fig. 16). At this time, the guide path L may be formed at the guide portion, and the guide path L may guide the wire 2 to enter the container 21 through the notch 211b, then to pass through the adhesive in the container 21, and finally to exit the container 21 through the through hole 211 a.

In some examples, when the coil 3 is wound, the wire 2 may enter the container 21 from the notch 211b along the guide path L, then pass through the adhesive in the container 21, and finally pass out of the container 21 from the through hole 211a, thereby impregnating the wire 2 with the adhesive.

Examples of the present disclosure are not limited thereto, and the guide may extend the wire 2 through the container 21 laterally, or may extend the wire vertically through the container 21. In some examples, the container 21 may have a plurality of guides so that a plurality of wires 2 may be guided at the same time. In some examples, one guide may guide a plurality of wires 2 at the same time, in which case, it is possible to guide a plurality of wires 2 at the same time, improving the winding efficiency.

In some examples, the coating mechanism 20 may further include a wire pressing portion 22 (see fig. 15) for applying pressure to the wire 2 to damp sliding of the wire 2. In this case, it is possible to provide the wire 2 with a tension during the winding process, so that the wire 2 is kept taut, to make the winding process more stable.

In some examples, during the winding process, the wire 2 may be passed through the wire pressing portion 22 to apply pressure to the wire 2, thereby maintaining the wire 2 in a tensioned state. In this case, the wire 2 is prevented from being loosened during the winding process to affect the winding process.

In some examples, the wire pressing portion 22 may include a pressure block 221, a first pressure piece 222, a second pressure piece 223, and an outer wall 224 (see fig. 17). In some examples, the pressure block 221, the first pressure plate 222, and the second pressure plate 223 may have the same bottom surface shape.

In some examples, the outer wall 224 may have a cavity 212 formed therein. In some examples, the cavity 212 may have a cross-section that is the same shape as the bottom surfaces of the pressure block 221, the first pressure plate 222, and the second pressure plate 223. In some examples, the cross-section of the cavity 212 may be equal to or slightly larger than the bottom surfaces of the pressure block 221, the first pressure plate 222, and the second pressure plate 223. First pressure plate 222 and second pressure plate 223 may be placed in cavity 212 as described above. In the above-described chamber 212, the second pressure sheet 223 may be disposed at the lowermost layer, the first pressure sheet 222 is stacked on the second pressure sheet 223, and the pressure block 221 is stacked on the first pressure sheet 222. In some examples, the depth of pocket 212 may be equal to or slightly greater than the sum of the thickness of first pressure sheet 222 and the thickness of second pressure sheet 223.

Additionally, in some examples, the cavity 212 may have a cylindrical shape, and the first pressure plate 222 and the second pressure plate 223 may have a flat cylindrical shape. When the first pressure plate 222 and the second pressure plate 223 are placed in the cavity 212, the cavity 212 can be filled in cooperation with the cavity 212.

In some examples, the first pressure sheet 222 and the second pressure sheet 223 may be silicon sheets. The pressure block 221 may be an iron block.

In some examples, the outer wall 224 may also be formed with a notch 224a and a notch 224b (see fig. 18). In addition, in some examples, when the cavity 212 formed by the outer wall 224 is in the shape of a cylinder, the notch 224a and the notch 224b may be disposed opposite to each other on the circumference of the cylinder.

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, i.e., the outer wall 224 and the outer wall 211 share a single notch and are coupled together. At this time, the guide path L may pass through the pressing line portion 22. The guiding path L may guide the wire 2 to pass through the notch 224b into the pressing portion 22, pass through the gap 224a (also the notch 211 b) and then pass through the adhesive in the cavity 212, and then pass through the through hole 211a after passing through the gap between the first pressure piece 222 and the second pressure piece 223, and then pass through the pressing portion 22 into the container 21.

In some examples, when winding the coil 3, the wire 2 may be passed through the notch 224b into the wire pressing portion 22, and then passed between the first pressure piece 222 and the second pressure piece 223, and then passed out of the notch 224a (also the notch 211 b) into the container 21. After entering the container 21, the wire 2 passes through the adhesive in the cavity 212, passes through the through hole 211a, 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 wire 2 can be clamped between the first pressure piece 222 and the second pressure piece 223, and damping of sliding of the wire 2 is achieved.

Examples of the present disclosure are not limited thereto, and the first pressure sheet 222 and the second pressure sheet 223 may be other sheet-shaped objects, such as a rubber sheet, a plastic sheet, a metal sheet, and the like. In some examples, the first pressure plate 222 and the second pressure plate 223 may be one soft block-shaped object having a channel through which the wire 2 may pass. The pressure block 221 presses the soft block-shaped object to deform the soft block-shaped object and thus deform the channel, thereby applying pressure to the wire 2. In some examples, the first pressure plate 222 and the second pressure plate 223 may also be two contoured pulleys, through which the wire 2 passes, thereby clamping the wire 2.

Fig. 19 is an exploded perspective view showing the adjusting mechanism 60 in the winding device 1 shown in fig. 1. The adjustment mechanism 60 is described in detail below in connection with fig. 19.

In some examples, the winding device 1 may further comprise an adjustment mechanism 60 (see fig. 1 and 2) to adjust the spacing between the first clamping member 13 and the second clamping member 14. In this case, the distance between the first clamping piece 13 and the second clamping piece 14 can be adjusted by operating the adjusting mechanism 60, so that the first clamping piece 13 and the second clamping piece 14 can be made to better clamp the wire 2 and the coil 3.

In addition, in some examples, the adjustment mechanism 60 may include an adjustment member 61, an adjustment bracket 62, a connection member 63 (see fig. 19), and a push rod (not shown). In some examples, the adjustment member 61 may be movably disposed to the adjustment bracket 62. A push rod may be placed in the auxiliary spool 15 and used to push the second clamp 14. The connection member 63 may be used to connect the adjustment member 61 and the push rod. In use of the winding device 1, the adjustment member 61 may be operated to push the push rod, which then pushes the second clamping member 14, thereby adjusting the spacing of the first clamping member 13 from the second clamping member 14. In this case, the spacing between the first clamping member 13 and the second clamping member 14 can be adjusted more conveniently.

In addition, in some examples, the adjustment member 61 may be a bolt that is generally in the shape of a small cylinder that is the head of the bolt superimposed with a long cylinder that is the tail of the bolt. The adjustment bracket 62 may be comprised of a T-shaped base and a bracket generally formed of a rectangular parallelepiped and a half cylinder joined together. In some examples, the thickness of the cuboid may be the same as the thickness of the half cylinder. The semi-cylinders on the bracket may be provided with through holes capable of receiving bolts. The bolt may be inserted into the through hole and pass out of the through hole to expose the tail. The tail of the bolt may be coupled with a connector 63. In some examples, the bolt and the connector 63 may be coupled in a coaxial manner. The connecting piece 63 may be formed by stacking two cylinders, which are a large cylinder and a small cylinder, respectively, wherein the radius of the bottom surface of the large cylinder is slightly larger than that of the small cylinder, the bottom surface of the large cylinder is connected with the tail part of the bolt, and the bottom surface of the small cylinder is connected with the push rod. The interior of the auxiliary winding shaft 15 may be hollowed out to receive the push rod. The push rod is placed into the auxiliary winding shaft 15, the push rod head may be connected with the second clamping member 14 and the push rod tail may be coupled with the connecting member 63. In some examples, the bolt, the through hole of the adjustment bracket 62, the connector 63, and the central axis of the push rod may be on the same horizontal line. In some examples, the bolt, the through-hole of the adjustment bracket 62, the connector 63, and the central axis of the pushrod may be collinear.

In some examples, when using the winding device 1, the bolt may be rotated to screw the bolt into or out of the through hole of the adjustment bracket 62, so that the length of the portion of the bolt exposed from the through hole of the adjustment bracket 62 may be changed. During the process of screwing the bolt into or out of the through hole of the adjusting bracket 62, the bolt can push the connecting piece 63, then the connecting piece 63 can push the push rod, and finally the push rod can push the second clamping piece 14, so that the distance between the first clamping piece 13 and the second clamping piece 14 can be adjusted.

Examples of the present disclosure are not limited thereto, and a scale may be provided on the push rod to measure the distance the second clamping member 14 is pushed. The bolts may also be provided with graduations for precisely adjusting the spacing between the first clamping member 13 and the second clamping member 14.

Fig. 20 is a perspective view showing the synchronization mechanism 50 in the winding device 1 shown in fig. 1. The synchronizing mechanism 50 is described in detail below in connection with fig. 20.

In some examples, the winding mechanism 10 may further include a synchronizing mechanism 50 (see fig. 1 and 2) that synchronizes rotation of the spool 11 with the auxiliary spool 15. In this case, the rotation of the spool 11 in synchronization with the auxiliary spool 15 can be maintained during the rotation of the spool 11 to drive the wire 2 to be wound into the coil 3.

In addition, in some examples, the synchronization mechanism 50 may include a first gear 51, a second gear 52, a third gear 53, a fourth gear 54, and a synchronization shaft 55 (see fig. 20). In some examples, the first gear 51 may be connected with the spool 11 and rotate in synchronization with the spool 11. The second gear 52 may be connected to the auxiliary winding shaft 15 and rotate in synchronization with the auxiliary winding shaft 15. The third gear 53 is in meshed connection with the first gear 51. The fourth gear 54 is in meshed connection with the second gear 52. The third gear 53 and the fourth gear 54 may be coupled to both ends of the synchronizing shaft 55, and the synchronizing shaft 55 may be capable of maintaining synchronous rotation of the third gear 53 and the fourth gear 54. When the spool 11 rotates, the first gear 51 can be driven, the first gear 51 can drive the third gear 53, the third gear 53 can drive the fourth gear 54 through the synchronizing shaft 55, the fourth gear 54 can drive the second gear 52, the second gear 52 can drive the auxiliary spool 15 to rotate, and finally synchronous rotation of the auxiliary spool 15 and the spool 11 can be realized.

In some examples, the first gear 51 and the second gear 52 may be gears of the same size and number of teeth. In some examples, the third gear 53 and the fourth gear 54 may be gears of the same size and number of teeth.

Examples of the present disclosure are not limited thereto, and the synchronizing shaft 55 for maintaining the third gear 53 and the fourth gear 54 to rotate in synchronization may be replaced with other same-functioning mechanical structures, for example, mechanical structures constituting the same function by some gear combinations.

In some examples, the winding device 1 may further comprise a holder 30 (see fig. 1 and 2).

In some examples, mount 30 may have a base 31, a wire spool bearing mount 32 that mates with wire spool 11, and an auxiliary bearing mount 33 that mates with auxiliary wire spool 15 (see fig. 21).

The base 31 may be a rectangular parallelepiped with a flat large bottom surface, which may be placed at the lowest level to provide stable support for the mount 30. The auxiliary bearing holder 33 and the wire winding bearing holder 32 may be fixed to the rectangular parallelepiped two broad sides of the base 31, respectively, and disposed opposite to each other. In some examples, the central axis of the coil bearing 34 may be on the same level as the central axis of the auxiliary coil bearing 36. In some examples, the central axis of the line reeling synchronization bearing 35 may be on the same level as the central axis of the auxiliary line reeling bearing 37.

In some examples, the winding device 1 may further comprise a drive mechanism 40 (see fig. 1 and 2) connected to the spool 11. The drive mechanism 40 may be used to drive rotation of the spool 11. In this case, the wire spool 11 can be driven to rotate by operating the driving mechanism 40 to drive the wire 2 to be wound into the coil 3, so that the process of winding the wire 2 into the coil 3 can be powered in the winding device 1.

Examples of the present disclosure are not limited thereto, and the driving form of the driving mechanism 40 may also be motor driving, fuel engine driving, wind driving, or the like. In some examples, the drive mechanism 40 may be provided with a control device that controls the stopping or movement of the drive mechanism 40. The control device may also be provided with a control system that can precisely control the speed and time of operation of the drive mechanism 40.

In some examples, the drive mechanism 40 may have a handle portion 41 for gripping (see fig. 22). In this case, a portion for facilitating gripping can be provided when the spool 11 is manually driven to rotate.

In addition, in some examples, the driving mechanism 40 may further include a connection block 42 (see fig. 22) for connecting the wire spool 11 and the handle portion 41. In some examples, the connection block 42 may be substantially block-shaped, having a groove 11d for coupling the wire spool 11 and a through hole for coupling the handle. The projection 11e of the wire spool 11 is inserted into the groove 11d to couple the wire spool 11 and the connection block 42. The handle portion 41 may be an elongated cylindrical handle, the end of which may also be provided with threads, in which case the through-hole of the connection block 42 may also be provided with threads that mate with the end of the handle, in which case the handle can be screwed into the through-hole of the connection block 42 to couple the connection block 42 and the handle.

In some examples, the handle portion 41 may also be provided with mechanical structure for reducing the driving torque to achieve a labor saving effect. In some examples, the adhesive may be selected from at least one of polyurethane adhesive, epoxy, and silicone. In this case, the adhesive may be made biocompatible.

In some examples, the wire 2 may be a stranded wire consisting of a plurality of bare wires. In this case, a coil wound from a litz wire can be wound.

Examples of the present disclosure are not limited thereto, and the metal wire used for the stranded wire may be copper wire, aluminum wire, iron wire, or the like. In some examples, the material of the metal wire 2 may also be a combination of a plurality of different metals. In some examples, the metal wire used may also be a single wire.

In some examples, coil 3 may be a planar coil. In this case, the planar coil occupies a small volume, and the wound coil 3 can be easily placed into a human body.

Examples of the present disclosure are not limited thereto, and the number of turns of the wound coil 3 may be selected according to actual needs, and may be ten turns, twenty turns, thirty turns, or the like. In some examples, the wound coil 3 may also be a solid coil.

Fig. 23 is a flowchart showing a winding method of the coil 3 according to the present disclosure. The coil 3 winding method according to the present disclosure is described in detail below with reference to fig. 23.

In some examples, the winding method (which may also be simply referred to as a winding method) of the biocompatible coil 3 may include the steps of: a wire 2, a winding device 1 having a winding mechanism 10 and a coating mechanism 20 for winding the wire 2 into a coil 3, and an adhesive having biocompatibility are prepared (step S100). The adhesive is applied to the wire 2 by the coating mechanism 20 (step S200). And the adhesive-coated wire 2 is fixed to the winding mechanism 10, and the wire 2 is wound into the coil 3 by the winding mechanism 10 (step S300).

In some examples, in step S100, the metal wire 2 for winding into the coil 3 and an adhesive having biocompatibility may be prepared.

In some examples, the winding device 1 may have a wire spool 11 for winding the wire 2.

In some examples, the spool 11 may have a wire core 12 that is rotatable with the spool 11.

In some examples, the coating mechanism 20 may have a container 21 for holding an adhesive.

In some examples, the container 21 may also have a guide for guiding the wire 2 such that the wire 2 is impregnated with an adhesive. In this case, the wire 2 passes through the adhesive along the guide in the container 21 to apply the adhesive to the wire 2, so that the process of passing the wire 2 through the container 21 can be more stabilized.

In some examples, the winding device 1 may also have a first clamp 13 and a second clamp 14 for clamping the wire 2 and the coil 3.

In some examples, the winding device 1 may also have a sizing sleeve 16 for fixing the first clamp 13 and the second clamp 14.

In some examples, in step S200, the coating mechanism 20 may apply an adhesive to the wire 2.

In some examples, in step S200, the wire 2 may be passed through the container 21 such that the adhesive is applied to the wire 2. In this case, the wire 2 can be more sufficiently coated with the adhesive.

In some examples, in step S200, the wire 2 may pass through the container 21 along the guide. In this case, the process of coating the wire 2 with the adhesive can be made more stable.

In some examples, the adhesive may be injected through the opening 141 to the coil 3 sandwiched between the first and second clamps 13 and 14, so that the coil 3 is sufficiently covered with the adhesive. In some examples, adhesive may be injected between the first clamp 13 and the second clamp 14 from the opening 141 after the winding of the coil 3 is completed. In this case, the adhesive can be applied to the coil 3 again so that the coil 3 is more sufficiently coated with the adhesive.

In some examples, pressure may also be applied to the wire 2 to maintain the wire 2 in tension. In this case, the wire 2 can be prevented from being loosened during the winding process to affect the winding process.

In some examples, the wire 2 may be passed through the wire pressing portion 22 to apply pressure to the wire 2.

In some examples, wire 2 may be passed between first pressure plate 222 and second pressure plate 223.
