[0002] Coils are important components in various electronic products. Before welding the coils to electronic products, it is usually necessary to press the tail of the wire in the coil into a specific shape so that the width and thickness of the tail of the wire meet the welding requirements.

[0003] At present, a mold is usually used to flatten the tail of the wire. After being flattened, the tail of the wire will be stretched and deformed in the width direction, which can easily cause the tail of the wire to be stuck in the mold, making it difficult to demold the flattened wire. In addition, since the flattened surface of the tail of the wire is the welding surface, the flatness of the flattened surface must be good to ensure the welding quality. If demolding is forced, the flattened surface of the tail of the wire is easily damaged, thereby affecting the welding quality. Summary of the invention

[0042] Referring to FIG1 , an embodiment of the present application provides a wire pressing device for pressing wires. The wires may be flat wires, round wires or wires of other shapes, which are not limited here. In the present embodiment, the wires refer to the tail ends of the wires in the flat wire coils 30. Specifically, in conjunction with FIG2 to FIG5 , a wire pressing device of an embodiment includes a first mold 10 and a second mold 20, wherein the first mold 10 is used to carry the wires, the first mold 10 is provided with a first limiting portion 113 for limiting one side of the wires, the second mold 20 is arranged opposite to the first mold 10, the second mold 20 includes a pressing block 21, and the pressing block 21 is provided with a second limiting portion; the second mold 20 can move in a direction close to or away from the first mold 10, so that the wire pressing device enters a mold closing state or a mold opening state. Referring to Figures 6 and 7, in the mold closing state, the pressing block 21 can press against the wire, and the second limiting portion is arranged opposite to the first limiting portion 113 and can limit the other side of the wire; referring to Figures 4 and 5, in the mold opening state, the pressing block 21 and the second limiting portion are separated from the wire.

[0043] In the above-mentioned wire pressing device, a first limiting portion 113 is provided on the first mold 10, and a second limiting portion is provided on the pressing block 21 of the second mold 20. When the second mold 20 moves toward the direction close to the first mold 10 to enter the mold closing state, the pressing block 21 can be pressed against the wire, and the second limiting portion and the first limiting portion 113 can respectively limit the wire from the opposite sides of the wire (for example, from the two sides in the width direction of the flat wire), so that the wire can be pressed into a required shape. When the second mold 20 moves toward the direction away from the first mold 10 to enter the mold separation state, the pressing block 21 and the second limiting portion are separated from the wire. At this time, the limiting of the wire by the first limiting portion 113 and the second limiting portion can be released, ensuring that the flattened wire is no longer constrained, avoiding the flattened wire from being stuck in the first mold 10, making it easier for the flattened wire to separate from the first mold 10, and preventing damage to the wire during demolding.

[0044] Referring to Fig. 5, optionally, in one embodiment, the first mold 10 is provided with an avoidance groove 112 and a receiving groove 111 for receiving the wire, the avoidance groove 112 is located on one side of the receiving groove 111 and is connected to the receiving groove 111, and the first limiting portion 113 is a side groove wall of the receiving groove 111 away from the avoidance groove 112. When pressing the wire, by placing the tail end of the wire into the receiving groove 111, the side groove wall of the receiving groove 111 away from the avoidance groove 112 can limit one side of the wire. It can be understood that in another embodiment, the first limiting portion 113 can also be a protrusion convexly provided on the first mold 10. When pressing the wire, the protrusion can be abutted against one side of the wire to limit one side of the wire. The avoidance groove 112 is used to cooperate with the second limiting portion on the pressing block 21 in the mold closing state.

[0045] Referring to Figure 7, specifically, in one embodiment, the second limiting portion includes a limiting block 23, which is connected to the pressing block 21, and at least part of the limiting block 23 protrudes from one end of the pressing block 21 close to the first mold 10. In the mold closing state, the limiting block 23 is inserted in the avoidance groove 112, thereby ensuring that the limiting block 23 can limit the other side of the wire when the mold is closed, and at the same time avoiding interference between the limiting block 23 and the second mold 20.

[0046] Furthermore, the depth of the avoidance groove 112 is greater than the depth of the accommodating groove 111, and the shape of the avoidance groove 112 matches the shape of the limit block 23. In the mold closing state, the limit block 23 fits with the groove wall of the avoidance groove 112. In this way, the limit block 23 cooperates with the avoidance groove 112 to guide and limit the downward pressing action of the second mold 20, and can ensure that the first mold 10 and the second mold 20 are better aligned and matched when the mold is closed to prevent interference and mold collapse.

[0047] Furthermore, a plurality of accommodating grooves 111 may be provided on the first mold 10, and the accommodating grooves 111 are arranged at intervals, and each accommodating groove 111 is connected to an avoidance groove 112. Correspondingly, a plurality of pressing blocks 21 may be provided on the second mold 20, and each pressing block 21 is provided with a limit block 23. By the one-to-one correspondence between the pressing blocks 21 and the accommodating grooves 111, multiple wires can be pressed simultaneously in one mold closing, thereby improving production efficiency.

[0048] Referring to FIG. 1 , the first mold 10 includes a first mold frame 12 and a mold base 11 disposed on the first mold frame 12. The mold base 11 is used to carry the coil 30 formed by winding the wire. The first limit portion 113 is disposed on the mold base 11, that is, the accommodating groove 111 and the avoidance groove 112 are both provided on the mold base 11. Preferably, the accommodating groove 111 is a blind groove, and the avoidance groove 112 passes through the mold base 11. Further, the second mold 20 also includes a second mold frame 22, one end of the pressing block 21 is connected to the second mold frame 22, and the other end of the pressing block 21 extends toward the direction close to the first mold 10.

[0049] Continuing to refer to FIG. 1 , optionally, in one embodiment, the first mold frame 12 is provided with a guide column 13, the guide column 13 extends in the direction close to the second mold frame 22, the second mold frame 22 is provided with a guide hole (not shown), and the guide column 13 is inserted into the guide hole and slides with the guide hole. Through the guiding effect of the guide column 13, it can be ensured that the second mold 20 moves closer to or away from the first mold 10 more smoothly, and the first mold and the second mold 20 are aligned when the mold is closed, so as to avoid interference and mold collapse. Further, the first mold frame 12 is provided with a plurality of guide columns 13, and the second mold frame 22 is correspondingly provided with a plurality of guide holes, and each guide column 13 is correspondingly inserted into the guide hole. For example, in this embodiment, the first mold frame 12 is provided with four guide columns 13, and the four guide columns 13 are respectively arranged at the four corners of the first mold 10, and the second mold frame 22 is correspondingly provided with four guide holes, thereby improving the guiding and limiting effect of the second mold 20. It is understandable that in other embodiments, the guide column 13 may also be arranged on the second mold frame 22, and the guide hole may also be opened through the first mold frame 12, so that the second mold 20 can be guided and limited by the cooperation between the guide column 13 and the guide hole.

[0050] Continuing to refer to FIG. 1 , in one embodiment, the first mold frame 12 is provided with a height-limiting column 14, which extends in a direction close to the second mold frame 22, and in the mold-closing state, the height-limiting column 14 abuts and cooperates with the second mold frame 22, thereby limiting the downward pressing stroke of the second mold 20, ensuring that the wire is pressed to a suitable thickness, and preventing the second mold 20 from colliding with the first mold 10. Further, the first mold frame 12 can be provided with a plurality of height-limiting columns 14. For example, in the present embodiment, the first mold frame 12 is provided with two height-limiting columns 14, and the two height-limiting columns 14 are respectively arranged on both sides of the first mold frame 12, thereby improving the limiting effect on the second mold 20. It is understandable that in other embodiments, the height-limiting column 14 can also be provided on the second mold frame 22, and in the mold-closing state, the height-limiting column 14 abuts against the first mold frame 12, so that the downward pressing stroke of the second mold 20 can also be limited.

[0051] Referring to FIG8 , in one embodiment, a positioning post 15 is convexly provided on the mold base 11, and the positioning post 15 is used to penetrate into the coil 30, so as to realize the positioning of the coil 30 and prevent the displacement of the coil 30 during the pressing process. Further, a plurality of positioning posts 15 can be provided on the mold base 11, for example, two positioning posts 15 are provided in this embodiment, and the two positioning posts 15 are respectively penetrated into the two coils 30 to position the two coils 30.

[0052] Referring to Figure 9, the second mold 20 also includes a clamping assembly 24, which is arranged on the side of the second mold frame 22 close to the first mold 10. In the mold closing state, the clamping assembly 24 can press against the side of the coil 30 away from the first mold 10, thereby preventing the coil 30 from escaping from the positioning column 15, thereby improving the positioning stability of the coil 30 when pressing the wire.

[0053] Specifically, in one embodiment, the pressing assembly 24 includes a pressing plate 243, a connecting column 241 and an elastic member 242, wherein the pressing plate 243 is arranged on a side of the second mold frame 22 close to the mold base 11 and is arranged opposite to the mold base 11. One end of the connecting column 241 is connected to the pressing plate 243, and the other end is slidably connected to the second mold frame 22; the elastic member 242 is sleeved on the connecting column 241, and one end of the elastic member 242 abuts against the second mold frame 22, and the other end abuts against the pressing plate 243. In this way, the pressing plate 243 can move up and down relative to the second mold frame 22. In the mold closing state, the elasticity of the elastic member 242 is used to make the pressing plate 243 and the coil 30 form an elastic contact, which not only ensures that the pressing plate 243 can press the coil 30, but also prevents the coil 30 from being damaged by excessive pressure. Preferably, the coil 30 can be a spring.

[0054] The technical features of the above-described embodiments may be arbitrarily combined. To make the description concise, not all possible combinations of the technical features in the above-described embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0055] The above-described embodiments only express several implementation methods of the present application, and the descriptions thereof are relatively specific and detailed, but they cannot be construed as limiting the scope of the patent application. It should be pointed out that, for a person of ordinary skill in the art, several variations and improvements can be made without departing from the concept of the present application, and these all belong to the protection scope of the present application. Therefore, the protection scope of the patent application shall be subject to the attached claims.
