Detailed Description

The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application, and it is obvious that the described embodiments are some, but not all, embodiments of the present application. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present application.

Fig. 1 to fig. 3 are schematic views of a winding device, a winding assembly and a wire supplying assembly according to an embodiment of the present application. As shown in the drawings, the winding device 1 includes a winding assembly 10 and a wire supply assembly 11. The winding assembly 10 includes a first base frame 100, a first driving module 101, a winding former 102, and a rotating former 103. The first driving module 101 is movably disposed on the first base frame 100 along a first direction DR 1. The winding former 102 is pivotally disposed on the first driving module 101 in a first direction DR1 and is used for carrying the workpiece 2. The rotating mold 103 is sleeved on the winding mold 102 and drives the winding mold 102 to rotate. The wire feeding assembly 11 is disposed at one side of the winding assembly 10, and the wire feeding assembly 11 includes a second base frame 110, a second driving module 111, a third driving module 112, and a wire feeding module 113. The second driving module 111 is pivotally disposed on the second base frame 110 in a second direction DR 2. The third driving module 112 is movably disposed on the second driving module 111 along the third direction DR 3. The wire supplying module 113 is disposed on the third driving module 112 and is used for supplying a wire to the workpiece 2 on the winding former 102 to form the coil 3. With the above configuration, the present application can dispose the coil 3 on the arc-shaped workpiece 2 and precisely adjust the distance of each line segment in the coil 3, to realize a winding apparatus 1 that can form a precise coil 3 on the arc-shaped workpiece 2.

In the present embodiment, the first driving module 101 may be, but is not limited to, assembled on the first base frame 100 in a sliding connection manner; specifically, the first driving module 101 is displaced in the first direction DR1 relative to the first base frame 100.

In order to make the technical means and technical effects of the present application more comprehensible, the above-mentioned components and their variations are explained in detail below.

Referring to fig. 1 and 2, the winding assembly 10 supports the workpiece 2 through a winding die 102 and a rotating die 103, and drives the workpiece 2 to rotate along a first direction DR 1. In addition, the wire winding assembly 10 also drives the workpiece 2 to move along the first direction DR1 through the first driving module 101.

In some embodiments, the first driving module 101 may include a linear motion shaft 1010, a first linkage member 1011, and a first driver 1012. The linear movement shaft 1010 extends along the first direction DR1 and is disposed on the first base frame 100. The first linking member 1011 is disposed on the linear motion shaft 1010. The first driver 1012 drives the first linking member 1011 to move along the linear motion axis 1010, i.e., along the first direction DR 1. For example, the first driver 1012 may be a driving motor device, which converts electric energy into mechanical energy to drive the first linkage member 1011 to reciprocate linearly. However, the present application is not limited thereto, and in other embodiments, the first actuator 1012 can also be an oil cylinder or a pneumatic cylinder, etc. with the same or similar effect, so as to achieve the same effect.

In some embodiments, the first driving module 101 may further include two stop blocks 1013, and the two stop blocks 1013 are respectively disposed at two ends of the linear motion shaft 1010 to limit a moving range of the first linking member 1011 in the first direction DR 1.

In some embodiments, the winding former 102 has an arcuate winding wall 1020. The arc-shaped wire winding wall 1020 is for carrying and contacting the workpiece 2, and thus may have a shape corresponding to the workpiece 2. For example, the arcuate wire wrap wall 1020 may be, but is not limited to, hemispherical in shape as shown in fig. 2. In other embodiments, the arc-shaped winding wall 1020 of the winding former 102 may also be in the shape of a semi-ellipse or a profile.

In some embodiments, the winding former 102 may be detachably disposed on the first driving module 101. In this way, by replacing the winding former 102 with a different size or shape, the winding device 1 can be adapted to workpieces 2 with different shapes (e.g., oval or circular) and different sizes. The detachable connection may be a screw fastening, a snap fit, or the like, as known to those skilled in the art.

In some embodiments, a motor unit or a unit connected to the motor unit may be disposed in the rotary die 103 as a driving unit to drive the winding die 102 to rotate.

Referring to fig. 1 and 3, the wire supply assembly 11 is disposed at one side of the winding assembly 10 and is used for disposing the material (i.e., the wire) of the coil 3 on the workpiece 2 of the winding former 102. The wire supply assembly 11 drives the wire supply module 113 to rotate around the second direction DR2 by the second driving module 111, and drives the wire supply module 113 to move in the third direction DR3 by the third driving module 112. That is, the wire supplying module 113 may form the coil 3 by disposing the wire on the workpiece 2 at a fixedly set angle (or set stress) in accordance with the shape of the arc-shaped wire winding wall 1020 (or the workpiece 2). For example, the wire feeding head 1130 of the wire feeding module 113 can be perpendicular to the arc-shaped winding wall 1020 through the second driving module 111 and the third driving module 112. In this way, the conductor can be subjected to a constant setting stress during the setting on the workpiece 2, so that each segment of the coil 3 has the same forming conditions.

In some embodiments, the second driving module 111 may include a rotating shaft 1110, a second linkage 1111, and a second driver 1112. The shaft 1110 extends along a second direction DR2 and is disposed on the second base frame 110. One side of the second linkage 1111 is connected to the rotating shaft 1110. The second driver 1112 drives the second linkage 1111 to deflect around the rotation shaft 1110. For example, the second driver 1112 may be a driving motor, which converts electrical energy into mechanical energy to drive the second linkage 1111 to operate. However, the present application is not limited thereto, and in other embodiments, the second driver 1112 may be an oil cylinder or an air cylinder with the same or similar effect to achieve the same function.

The third driving module 112 is disposed on the second driving module 111 and is configured to drive the wire supplying module 113 disposed thereon to move in the third direction DR 3. For example, the third driving module 112 may include a slider, a slide rail, and a third driver. The slider extends in a third direction DR 3. The sliding block is movably arranged on the sliding rail, and the third driver drives the sliding block to move along the sliding rail. However, the present application is not limited thereto. In other embodiments, the third driving module 112 may also be composed of a linear motion shaft, a bearing and a driver, or a hydraulic brake, a pneumatic brake …, etc., and the operation manner thereof may be similar to that of the first driving module 101, which is not described herein again. That is, the driving module known to those skilled in the art can be applied to the present application.

Please refer to fig. 1, 4 and 5, wherein fig. 4 and 5 are schematic views and cross-sectional views of a workpiece with a coil according to an embodiment of the present application. In some embodiments, when the workpiece 2 is composed of plastic, the winding device 1 may further include a heating module 104. The heating module 104 may be provided in the first driving module 101 of the wire winding assembly 10 and serves to heat the wire winding former 102. However, the present application is not limited thereto. In other embodiments, the heating module 104 may be disposed at other positions of the winding assembly 10 and connected to the winding former 102 to heat the winding former 102. For example, the heating module 104 may heat the winding former 102 by ultrasonic vibration. By heating the winding former 102, the workpiece 2 placed on the winding former 102 can be locally melted at a high temperature. Thus, the wires can be partially embedded in the workpiece 2 (as shown in fig. 5) or completely embedded in the workpiece 2 when disposed on the workpiece 2, instead of being connected by an adhesive. In addition, when the workpiece 2 and the coil 3 are applied to the wireless charging field, the distance between the wireless charging generating terminal and the receiving terminal can be shortened in a limited space by partially or completely embedding the coil 3 into the workpiece 2, thereby improving the charging efficiency.

As shown in fig. 5, in some embodiments, the coil 3 may have a first distance d1, the first distance d1 referring to a spacing between two adjacent line segments in the coil 3. Further, the present application may vary the first distance d1 by the first driving module 101. For example, the first distance d1 of the coil 3 is greater when the first driving module 101 drives the workpiece 2 to move faster. Conversely, the smaller the first distance d1 of the coil 3, the smaller the minimum first distance d1 may be zero, as the first drive module 101 drives the workpiece 2 to move more slowly.

As shown in fig. 5, in some embodiments, the coil 3 may also have a second distance d2 and an embedding amount, the second distance d2 referring to the diameter of the wire, and the embedding amount defined as the percentage of the second distance d2 embedded in the workpiece 2. That is, when the coil 3 is completely embedded (or embedded) in the workpiece 2, the embedding amount thereof is 100%. Preferably, the embedding amount may be between 10% and 100%. For example, the embedding amount may be 10%, 20%, 30%, 40%, 50%, 60%, 70%, 80%, 90%, or 100%, or a range consisting of any of the above values, which may be determined according to design requirements. Further, the present application may vary the embedding amount by the third driving module 112. For example, when the third driving module 112 drives the wire supplying module 113 closer to the workpiece 2, the stress applied to the workpiece 2 by the wire supplying module 113 is larger, and the portion of the coil 3 embedded in the workpiece 2 is larger (i.e., the embedding amount is larger). Conversely, when the third driving module 112 drives the wire supplying module 113 farther from the workpiece 2, the less the stress applied to the workpiece 2 by the wire supplying module 113, the less the coil 3 is embedded in the workpiece 2 (i.e., the lower the embedding amount).

In some embodiments, the material (wire) of the coil 3 may be an enameled wire (e.g., plastic for the outer layer and metal for the inner layer) or a pure metal wire. However, the present application is not limited thereto, and the material of the coil 3 may be any material known to those skilled in the art.

In the foregoing, the respective components of the winding device 1 of the present application and variations thereof have been explained in detail. Next, the entire operation of the winding device 1 will be further described below.

Referring to fig. 1, the operation of the winding device 1 is as follows: arranging a workpiece 2 on a winding former 102; the winding former 102 and the workpiece 2 positioned on the winding former are driven to rotate through the rotating former 103; providing wires through the wire supply module 113; driving the winding former 102 to move in a first direction DR1 by the first driving module 101, so that the wire is wound on the workpiece 2 to form a part of the coil 3; adjusting the wire supply module 113 to rotate coaxially in the second direction DR2 by the second driving module 111 so that the wire supply module 113 maintains an angle corresponding to the workpiece 2; adjusting the wire supply module 113 to move along the third direction DR3 by the third driving module 112 so that the wire supply module 113 maintains a distance corresponding to the workpiece 2; stopping rotating the winding former 102; the wire connected to the coil 3 is cut to obtain the workpiece 2 with the coil 3.

It should be noted that the above operation process is not all steps. In some embodiments, when the winding die 102 and the workpiece 2 thereon are driven to rotate by the rotating die 103, the workpiece 2 may also be heated by the heating module 104, so that the wire may be embedded in the workpiece 2 during the winding process.

To sum up, winding device in this application passes through the distance and the angle of first drive module, second drive module and third drive module adjustment work piece and wire to form the coil on curved work piece. In addition, the distance of each line segment in the coil can be accurately adjusted through the driving module. That is, the present application realizes a winding apparatus that can form a precise coil on an arc-shaped workpiece.

It should be noted that, in this document, the terms "comprises," "comprising," or any other variation thereof, are intended to cover a non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements does not include only those elements but may include other elements not expressly listed or inherent to such process, method, article, or apparatus. Without further limitation, an element defined by the phrase "comprising an … …" does not exclude the presence of other like elements in a process, method, article, or apparatus that comprises the element.

While the present embodiments have been described with reference to the accompanying drawings, it is to be understood that the invention is not limited to the precise embodiments described above, which are meant to be illustrative and not restrictive, and that various changes may be made therein by those skilled in the art without departing from the spirit and scope of the invention as defined by the appended claims.
