[0026] The present invention is achieved through the following technical solutions:

[0027] The present invention provides a winding process for an inter-winding coil antenna, comprising the following steps:

[0028] S1: Design the number of corresponding positioning members 1 according to the shape of the coil 3;

[0029] S2: assembling a plurality of positioning members 1 together to complete the assembly of the forming mold;

[0030] S3: The wire is rotated and wound around the limiting feet 14 of the plurality of positioning members 1, and the coil 3 is wound and formed;

[0032] S5: Use the shaping film 21 to put the coil 3 on the shaping film 21 so that the coil 3 is bonded and shaped.

[0033] Please refer to Figure 1 — Figure 4 The inter-winding coil antenna winding process of the present invention only requires assembling multiple positioning members 1 together first, and then rotating the wire around the limiting feet 14 of the multiple positioning members 1 after completing the assembly of the forming mold, and the coil 3 is wound into shape. Then, the multiple positioning members 1 are removed, and the coil 3 is released from the limiting feet 14 to form; finally, the shaping film 21 is used to release the coil 3 on the shaping film 21 so that the coil 3 is bonded to form. The inter-winding coil antenna winding process of the present invention changes the original traditional process of making the coil 3 through the FPC soft board circuit to winding the coil 3 antenna in the forming mold, which improves the winding efficiency, increases the application range of the wire, and simplifies the manufacturing process steps.

[0034] The winding process of the inter-wound coil antenna of the present invention is to use a molding mold to wind the coil 3, and according to the number of layers of the coil 3 required, prepare positioning members 1 with the same number of layers as the coil 3, and push out the limiting feet 14 of multiple positioning members 1 one by one so that multiple limiting feet 14 are fixed on the molding mold fixing member 2.

[0035] After the forming mold is assembled, the wire is wound around the outer periphery of the plurality of limiting legs 14 to form the coil 3 .

[0036] Then, the positioning members 1 of the molding die are all removed, and the coil 3 is released from the limiting legs 14 to be molded.

[0037] Finally, a shaping film 21 is used to bond the product onto the shaping film 21 for shaping.

[0038] Furthermore, a molding die for a winding process of an inter-wound coil antenna comprises a fixing member 2 and a plurality of positioning members 1 , wherein the plurality of positioning members 1 are plugged into each other and installed above the fixing member 2 .

[0039] The molding die of the present invention can be assembled by simply plugging a plurality of the positioning members 1 together, and has a simple structure and is easy to assemble.

[0040] Please refer to Figure 1 — Figure 4 The positioning member 1 includes a first positioning member 10 and a second positioning member 11. Both the first positioning member 10 and the positioning member 1 are provided with a limiting foot 14 and a socket 15. The limiting foot 14 of the second positioning member 11 is inserted into the socket 15 of the first positioning member 10, thereby making the second positioning member 11 and the first positioning member 10 plugged together.

[0041] In this embodiment, the molding die is provided with one first positioning member 10 and four second positioning members 11 .

[0042] In this embodiment, please refer to Figure 1 and Figure 2 The second positioning member 11 includes a first pressing plate 110 , a second pressing plate 111 , a third pressing plate 112 and a fourth pressing plate 113 .

[0043] Furthermore, the positions of the limiting feet 14 are expanded outward layer by layer, so that there is a winding space 142 between the multiple limiting feet 14 assembled together, and the wire is wound in the winding space 142.

[0044] Please refer to Figure 1 — Figure 3 The sockets 15 of the second pressing plate 111 , the third pressing plate 112 , and the fourth pressing plate 113 include a first socket 151 , a second socket 152 , a third socket 153 , and a fourth socket 154 .

[0045] In this embodiment, the first pressing plate 110 , the second pressing plate 111 , the third pressing plate 112 , and the fourth pressing plate 113 are identical in structure except for the length and position of the limiting foot 14 .

[0046] The limiting foot 14 of the fourth pressing plate 113 is inserted into the fourth socket 154 of the third pressing plate 112, the fourth socket 154 of the second pressing plate 111, the fourth socket 154 of the first pressing plate 110, and the fourth socket 154 of the first positioning member 10, thereby connecting the second pressing plate 111, the third pressing plate 112 and the first positioning member 10 together.

[0048] Similarly, the limiting foot 14 of the second pressing plate 111 can pass through the second insertion hole 152 of the first pressing plate 110 and the second insertion hole 152 of the first positioning member 10 , so that the second pressing plate 111 is installed on the first pressing plate 110 .

[0049] Please refer to Figure 1 — Figure 4 After the first pressing plate 110, the second pressing plate 111, the third pressing plate 112 and the fourth pressing plate 113 are plugged into each other, multiple second positioning members 11 are installed on the first positioning member 10, and the limiting feet 14 of the second positioning members 11 are inserted into the sockets 15 of the first positioning member 10.

[0050] Since the limiting feet 14 expand outward layer by layer, there is a winding space 142 between the limiting feet 14 of the first pressure plate 110 fixed on the first positioning member 10 and the limiting feet 14 of the second pressure plate 111, there is a winding space 142 between the limiting feet 14 of the second pressure plate 111 and the limiting feet 14 of the third pressure plate 112, and there is also a winding space 142 between the limiting feet 14 of the third pressure plate 112 and the limiting feet 14 of the fourth pressure plate 113, thereby facilitating the winding of the wire around the limiting feet 14 in the winding space 142.

[0051] In this embodiment, the length of the limiting foot 14 of the second pressing plate 111 is shorter than the length of the limiting foot 14 of the third pressing plate 112 . Similarly, the length of the limiting foot 14 of the third positioning member 1 is shorter than the length of the limiting foot 14 of the fourth pressing plate 113 .

[0052] Furthermore, the positioning member 1 further comprises a fixing plate 12 , the fixing plate 12 is provided with a plurality of positioning holes 121 , and the limiting legs 14 sequentially penetrate the insertion holes 15 and the positioning holes 121 and stop at the fixing member 2 .

[0053] In this embodiment, the fixing plate 12 is used to fix the limiting foot 14 and limit the wire from being wound under the fixing plate 12 .

[0054] Furthermore, a pressing block 120 is installed on the fixing plate 12 , and the pressing block 120 is located on one side of the fixing plate 12 .

[0056] Furthermore, the molding die is provided with a pin-out component 13 , and the pin-out component 13 includes a positioning pin 130 and a pin-out clamping pin 131 , and the positioning pin 130 and the pin-out clamping pin 131 are fixedly connected.

[0057] Furthermore, the positioning foot 130 is installed on the fourth positioning member 1 , the first positioning member 10 , the second positioning member 11 and the fixing plate 12 are all provided with a through hole 144 , and the pin-out pin 131 passes through the through hole 144 and stops at the fixing member 2 .

[0058] In this embodiment, the positioning foot 130 is installed on the fourth pressing plate 113 .

[0059] In this embodiment, each of the second positioning members 11 is provided with four limiting pins 14, and the first positioning member 10 is provided with three limiting pins 14. The first positioning member 10 is not provided with limiting pins 14 in the direction close to the pressing block 120, so that the guide limiting pins 140 of the second positioning member 11 pass through the insertion hole 15 and are fixed to the fixing plate 12, and the coil 3 can enter from the through hole 143 in the guide limiting pin 140 of the second positioning member 11, and be wound around the limiting pin 14 of the first positioning member 10, and after completing the winding of one layer of the coil 3, the wire is wound around the limiting pin 14 of the second pressing plate 111, and so on, after completing the winding of multiple layers of the coil 3, the wire is wound out from the pin-out clamping pin 131, and then the winding of one coil 3 is completed.

[0060] Furthermore, the limiting foot 14 includes a guiding limiting foot 140 and a limiting limiting foot 141 . The guiding limiting foot 140 is provided with a through hole 143 . The wire enters through the through hole 143 and is wound around the limiting limiting foot 141 .

[0061] In this embodiment, the wire enters under the fixed plate 12, passes through the through hole 143 of the guide limit pin 140, is then wound around the periphery of the limit pin 141, and is finally bent out through the outlet pin 131 to complete the winding of a coil 3.

[0062] After the coil 3 is wound, the plurality of positioning members 1 of the molding die are first removed from the fixing member 2, the wound coil 3 falls off from the limiting foot 14, and then the wound coil 3 is fitted with the shaping film 21, thereby completing the production of a finished product.

[0063] In this embodiment, after a finished product is completed, the plurality of positioning members 1 are moved back together and mounted on the fixing member 2 to continue winding the next coil 3 .
