[0016] Reference Figure 1-7This application proposes an embodiment of the common-mode winding machine with opposing clamping, which includes: The frame 10 is provided with a feeding station 11 and a winding station 12. The magnetic ring feeding mechanism 20 has a magnetic ring positioning head 21 that can be inserted into the ring of the magnetic ring. The magnetic ring feeding mechanism 20 can drive the magnetic ring positioning head 21 to move to the feeding station 11 or away from the feeding station 11. The magnetic ring clamping mechanism 30 has two oppositely distributed clamping arms 31, which can open or close. A conveying mechanism 40 is disposed on the frame 10. The magnetic ring clamping mechanism 30 is mounted on the conveying mechanism 40. The conveying mechanism 40 can convey two clamping arms 31 to the loading station 11 so that the two clamping arms 31 are distributed on opposite sides of the magnetic ring positioning head 21. The two clamping arms 31 close to clamp the magnetic ring positioning head 21 on the magnetic ring positioning, or convey two clamping arms 31 to the winding station 12. See attached document Figure 1 As shown, when the magnetic ring feeding mechanism 20 is feeding the magnetic ring, it drives the magnetic ring positioning head 21 with the inserted magnetic ring to move to the feeding station 11. The two clamping arms 31 open so that the distance between them is greater than the outer diameter of the magnetic ring. At this time, the conveying mechanism 40 conveys the two clamping arms 31 to move to the feeding station 11. The two clamping arms 31 are distributed on opposite sides of the magnetic ring positioning head 21. The magnetic ring clamping mechanism 30 then drives the two clamping arms 31 to approach to close and clamp the magnetic ring on the magnetic ring positioning head 21. After that, the magnetic ring feeding mechanism 20 drives the magnetic ring positioning head 21 away from the feeding station 11, so that the magnetic ring can be stably clamped between the two clamping arms 31, thus completing the feeding of the magnetic ring.
[0017] After the magnetic ring is loaded, the conveying mechanism 40 then conveys the magnetic ring clamping mechanism 30 to the winding station 12. The frame 10 is also provided with a winding mechanism 50, which is used to wind the part of the magnetic ring at the winding station 12 that is not clamped by the clamping arm 31, so as to facilitate the production of electronic components such as inductors with notches.
[0018] When the winding mechanism 50 winds the magnetic ring, the winding mechanism 50 winds the area outside the clamping arm 31 at the winding station 12, so that the winding mechanism 50 and the clamping arm 31 do not interfere with each other, thereby realizing the automated production of electronic components such as inductors with notches and improving production efficiency. Furthermore, the clamping position of the clamping arm 31 corresponds to the position of the notch, which can ensure that the wire is wound within the designed effective area and avoid the wire being accidentally wound to the notch. This ensures that the key parameters of the inductor, such as permeability and impedance characteristics, meet the design standards and improve the consistency of product performance.
[0019] The winding mechanism 50 has adjustable winding parameters, including the number of turns, winding speed, and conductor arrangement density, to meet different production needs.
[0020] Specifically, the magnetic ring clamping mechanism 30 includes a bracket 32 and a telescopic member 33. The two clamping arms 31 are a movable clamping arm and a fixed clamping arm, respectively. The bracket 32 is mounted on the conveying mechanism 40, the telescopic member 33 is mounted on the bracket 32, the fixed clamping arm is mounted on the bracket 32, and the movable clamping arm is mounted on the telescopic member 33. The telescopic member 33 can drive the movable clamping arm to move closer to or away from the fixed clamping arm.
[0021] In one embodiment, the bracket 32 is provided with two telescopic members 33, and two clamping arms 31 are respectively installed on the two telescopic members 33. The two telescopic members 33 extend and retract synchronously to realize the opening and closing of the two clamping arms 31.
[0022] In this embodiment, a structure of movable clamping arms and fixed clamping arms is adopted to reduce the number of parts and reduce costs.
[0023] Preferably, each clamping arm 31 is provided with a limiting boss 34 at the positions corresponding to both ends of the magnetic ring, and the magnetic ring extends between the two limiting bosses 34 of each clamping arm 31.
[0024] The slot structure formed by the two limiting bosses 34 can constrain the end of the magnetic ring. Together with the clamping arm 31, it can effectively prevent the magnetic ring from tilting due to uneven force during clamping. The stability of the magnetic ring's posture can ensure that the winding shaft and the magnetic ring axis are strictly collinear. During the winding process, even if the tension of the wire generates axial thrust or there is slight vibration during equipment operation, the magnetic ring can maintain a stable axial position, avoid axial displacement of the wire on the magnetic ring, and ensure production stability.
[0025] Preferably, the conveying mechanism 40 includes a first conveying component 41 and a second conveying component 42. The first conveying component 41 is mounted on the frame 10, the second conveying component 42 is mounted on the first conveying component 41, and the magnetic ring clamping mechanism 30 is mounted on the second conveying component 42. The first conveying component 41 is used to drive the magnetic ring clamping mechanism 30 to move along a first direction between the loading station 11 and the winding station 12, and the second conveying component 42 is used to drive the magnetic ring clamping mechanism 30 to move along a second direction, wherein the first direction and the second direction are perpendicular to each other.
[0026] When clamping and winding magnetic rings of different diameters, the positions of the fixed clamping arm and the movable clamping arm can be adjusted by the second conveying assembly 42 so that when the two clamping arms 31 move to the loading station 11, the two clamping arms 31 can be accurately distributed on the opposite sides of the magnetic ring.
[0027] In this embodiment, the magnetic ring feeding mechanism 20 includes a telescopic component 22 and a magnetic ring feeding component 23. The magnetic ring feeding component 23 is provided with a feeding channel 231, which has an inlet end and a feed end. The magnetic ring feeding component 23 is provided with a feed hole 233 that passes through the feed end. The telescopic component 22 is disposed on the side of the magnetic ring feeding component 23 away from the feeding station 11. The magnetic ring positioning head 21 is mounted on the telescopic end of the telescopic component 22. The telescopic component 22 is used to drive the magnetic ring positioning head 21 to extend and move through the feed hole 233 to the feeding station 11.
[0028] Referring to the attached drawings, several magnetic rings are stacked in the feeding channel 231. In the initial state, the magnetic ring positioning head 21 is located on the side of the feeding channel 231 away from the loading station 11. When the magnetic ring needs to be loaded, the telescopic end of the telescopic component 22 extends and drives the magnetic ring positioning head 21 to extend from the feeding hole 233 into the feeding channel 231 and insert into the ring of the magnetic ring. Then, the telescopic end of the telescopic component 22 continues to extend and causes the magnetic ring positioning head 21 to drive the magnetic ring to pass through the feeding hole 233 and move to the loading station 11.
[0029] Alternatively, the magnetic ring feeding mechanism 20 also includes a vibratory feeder (not shown in the figure), which is connected to the feed end and is used to supply magnetic rings into the feeding channel 231.
[0030] In this application, the magnetic ring clamping mechanism 30 further includes a rotary drive 35, which is connected to two clamping arms 31. It is used to drive the two clamping arms 31 and the clamped magnetic ring to rotate synchronously around the central axis of the magnetic ring. By controlling the rotation angle of the rotary drive 35, the coil range on the magnetic ring can be adjusted, which has a high degree of freedom.
[0031] In one embodiment, after the conveying mechanism 40 conveys the magnetic ring held by the two clamping arms 31 to the winding station 12, the winding mechanism 50 begins to wind the magnetic ring at the winding station 12. In this embodiment, the two clamping arms 31 are driven by the rotary drive 35 to rotate the magnetic ring for winding. For magnetic rings with different winding parameters, only the rotation speed and rotation angle of the rotary drive 35 need to be adjusted.
[0032] Of course, this utility model is not limited to the above-described embodiments. Those skilled in the art can make equivalent modifications or substitutions without departing from the spirit of this utility model. All such equivalent modifications and substitutions are included within the scope defined by the claims of this application.
