Description
Technical Field

[0002] In the inductor manufacturing process, the precise positioning and tension control of the copper wire are crucial factors affecting the winding quality. In traditional processes, the copper wire needs to be accurately drawn to the designated position on the magnetic core and maintained with appropriate tension, which places extremely high demands on the precision and stability of manual operation.
[0003] Currently, most production lines still rely on manual labor for copper wire positioning and tension adjustment, which has significant shortcomings: operators must manually pull both ends of the copper wire to the middle of the magnetic core, which is not only inefficient but also makes it difficult to ensure consistency in positioning each time; uneven force is easily caused when manually adjusting the tension, resulting in winding that is too tight or too loose. With the increasing requirements for winding accuracy in products such as high-frequency inductors and precision surface mount inductors, there is an urgent need to develop a wire pulling mechanism that can achieve automatic positioning and precise tension control.

For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or a connection through an intermediate medium; and they can refer to the internal communication between two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.
[0043] like Figures 1 to 9 As shown, this utility model has a wire pulling mechanism based on inductor winding, which is used to control the tension of copper wire. The wire pulling mechanism includes a clamping fixture 10, a wire clamping assembly 20, a release control assembly 30, and a clamping assembly 40.
[0044] Please see Figures 1 to 3 The clamping fixture 10 includes a magnetic core clamping module 11 and wire end clamping modules 12 symmetrically distributed on both sides of the magnetic core clamping module 11. For example... Figure 4 As shown, after the copper wire is wound around the outside of the magnetic core and then cut, the magnetic core with the copper wire wound around it is clamped in the magnetic core clamping module 11, and the ends of the copper wire are clamped in the end clamping module 12 respectively.
[0045] Specifically, the magnetic core clamping module 11 includes at least two elastic clamping arms 111 and a clamping member 112 sleeved on the outside of the elastic clamping arms 111. The outer wall of the elastic clamping arm 111 and the inner wall of the clamping member 112 are provided with corresponding conical inclined surfaces. The conical inclined surfaces of the two press against each other, causing the elastic clamping arm 111 to contract inward to clamp the magnetic core.
[0046] Specifically, the wire end clamping module 12 includes a connecting arm 121, a guide rod 122, a sliding member 123, and a first elastic element 124. The guide rod 122 is fixed to one end of the connecting arm 121, and a plug is provided at the end of the guide rod 122 away from the connecting arm 121. The sliding member 123 is slidably connected to the outside of the guide rod 122, and the first elastic element 124 is sleeved on the outside of the guide rod 122. One end of the first elastic element 124 is connected to the sliding member 123, and the other end of the first elastic element 124 is connected to the connecting arm 121. The first elastic element 124 drives the sliding member 123 to move along the guide rod 122 toward the plug side to clamp the end of the copper wire.
[0047] Please see Figure 5 and Figure 6The wire clamping assembly 20 includes a movable shaft 21, a telescopic drive module 22 driven by the movable shaft 21, and a rotation drive module 23 driven by the movable shaft 21. One end of the movable shaft 21 is fixedly provided with a first clamping arm 24 and a second clamping arm 25 arranged opposite to each other. The telescopic drive module 22 drives the first clamping arm 24 and the second clamping arm 25 to move linearly along the axial direction of the movable shaft 21, and the rotation drive module 23 drives the first clamping arm 24 and the second clamping arm 25 to rotate around the axis of the movable shaft 21. The first clamping arm 24 and the second clamping arm 25 are respectively used to clamp the wire ends. The telescopic drive module 22 and the rotation drive module 23 drive the first clamping arm 24 and the second clamping arm 25 to perform a combined linear and rotational motion to pull the wire ends at both ends of the copper wire, thereby adjusting the tension of the copper wire. Simultaneously, the position and angle of the wire ends can be adjusted to facilitate subsequent cutting and welding processes.
[0048] Specifically, the telescopic drive module 22 includes a push cylinder 221, the output end of which is connected to the movable shaft 21. The push cylinder 221 drives the movable shaft 21 to extend and retract linearly, thereby causing the first clamping arm 24 and the second clamping arm 25 to move closer to or away from the clamping fixture 10. The rotation drive module 23 includes a drive motor 231 and a first transmission wheel 232. A second transmission wheel 211 is provided on the outer wall of the movable shaft 21. A transmission belt (not shown in the figure) is sleeved on the outer side of the first transmission wheel 232 and the second transmission wheel 211. The rotation motor 231 drives the first transmission wheel 232 to rotate, and the second transmission wheel 211 rotates synchronously through the transmission belt, thereby driving the movable shaft 21 to rotate, realizing the rotation of the first clamping arm 24 and the second clamping arm 25 around the central axis of the movable shaft 21. Through the above-described drive mechanism, the combined movement of the first clamping arm 24 and the second clamping arm 25 can be realized, satisfying the complex movement path in the wire pulling process.
[0049] Specifically, the clamping assembly 20 also includes an angle detection sensor 26. The detection end of the angle detection sensor 26 is provided with a U-shaped sensing groove 27. A coaxially arranged rotating ring 212 is fixedly provided on the outer wall of the movable shaft 21, and the radial portion of the rotating ring 212 extends into the sensing groove 27. A radially penetrating detection notch 213 is provided on the rotating ring 212. It should be noted that the angle detection sensor 26 is an infrared sensor or a laser sensor, and an optical path parallel to the movable shaft 21 is formed in the sensing groove 27. When the movable shaft 21 rotates to a preset angle, the detection notch 213 aligns with the optical path, at which point the angle detection sensor 26 is triggered to generate a signal. Understandably, when the movable shaft 21 does not rotate to the preset angle, the rotating ring 212 will cut off the optical path, and the angle detection sensor 26 cannot generate a signal. The aforementioned sensing structure can sense the rotation angle of the movable shaft 21. At the same time, the angle detection sensor 26 is electrically connected to the rotation drive module 23. The two work together to enable the movable shaft 21 to rotate precisely to the preset angle, thereby improving the rotation accuracy of the first clamping arm 24 and the second clamping arm 25, and thus improving the wire pulling accuracy.
[0050] Please see Figure 7 and Figure 8 The release control component 30 includes an axially movable pusher 31, a drive cylinder 32, and a connecting frame 33. The drive cylinder 32 is driven to connect with the connecting frame 33, and the pusher 31 is fixed on the connecting frame 33. The drive cylinder 32 drives the pusher 31 to push against the sliding member 123. The sliding member 123 overcomes the elastic force of the first elastic element 124, causing the sliding member 123 to move away from the plug. At this time, the clamped copper wire is released so that the wire clamping component 20 can clamp the end of the copper wire.
[0051] Specifically, the pusher 31 has a cylindrical structure, and its axial center line is coaxial with the guide rod 122. The outer periphery of the sliding member 123 is provided with a radially protruding annular abutment 125. The inner diameter of the pusher 31 is larger than the maximum outer diameter of the plug 126, and the inner diameter of the pusher 31 is smaller than the maximum outer diameter of the abutment 125. When the pusher 31 moves axially along the guide rod 122, the plug 126 does not interfere with the pusher 31, and the plug 126 extends into the inner side of the pusher 31. However, the pusher 31 and the abutment 125 form mechanical interference, pushing the sliding member 123 to overcome the first elastic element 124 and generate displacement. Furthermore, in order to match the cylindrical design of the pusher 31, the pusher 31 has two symmetrically arranged wire passage notches 311 on the side facing the wire end clamping module 12. The wire passage notches 311 provide space for the movement of the copper wire end. During operation, the wire clamping assembly 20 clamps and drives the copper wire end through the wire passage notches 311, and then is pulled out of the wire end clamping module 12 to facilitate subsequent tension and position adjustment.
[0052] Please see Figure 9The clamping assembly 40 includes a vertically arranged lifting cylinder 41, a lifting plate 42 driven and connected to the lifting cylinder 41, and pneumatic grippers 43 fixed on the lifting plate 42. During operation, the lifting cylinder 41 drives the lifting plate 42 downwards, while the pneumatic grippers 43 tighten to clamp the two sides of the elastic clamping arm 111. This prevents the magnetic core from loosening during wire pulling, further improving the stability and precision of the machining process.
[0053] The working principle of the wire-pulling mechanism based on inductor winding involved in this utility model is as follows:
[0054] 1. The wire clamping assembly 20 extends into the wire end clamping module 12 and clamps the end of the copper wire;
[0055] 2. The release control component 30 extends into the wire end clamping module 12. At this time, the sliding member 123 moves away from the plug, so that the wire end of the copper wire is released.
[0056] 3. The wire clamping assembly 20 pulls the end of the copper wire to adjust the tension of the copper wire; at the same time, it drives the end of the copper wire to adjust its position.
[0057] Compared to existing technologies, the inductor winding-based wire pulling mechanism of this utility model includes a clamping fixture 10, a wire clamping assembly 20, and a release control assembly 30, achieving precise control and automated adjustment of copper wire tension. The clamping fixture 10 adopts a symmetrical layout of wire end clamping modules 12 and magnetic core clamping modules 11 to ensure accurate positioning of the copper wire end and the magnetic core. The wire clamping assembly 20, through the combined motion control of the telescopic drive module 22 and the rotation drive module 23, enables the first clamping arm 24 and the second clamping arm 25 to both axially stretch and adjust the tension, and rotate to adjust the winding angle. The release control assembly 30, through the mechanical interference cooperation between the pusher 31 and the wire end clamping module 12, achieves rapid switching of the copper wire clamping state. The overall structure of this mechanism is compact, and the components work together to significantly improve the yield and production efficiency of inductor winding, making it particularly suitable for the automated production of precision components such as high-frequency inductors.
[0058] The above description merely illustrates the preferred technical solution of this utility model, and while the description is relatively specific and detailed, it should not be construed as limiting the scope of the utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and this utility model also intends to include these modifications and variations.
