Description

Technical Field

[0001] The utility model belongs to the technical field of magnetic ring processing, in particular to a magnetic ring winding clamping device and a magnetic ring winding machine. Background Art

[0002] An inductor coil is a device that works on the principle of electromagnetic induction. It is formed by winding a wire around an insulating magnetic ring (hereinafter referred to as the magnetic ring) in circles. The existing magnetic ring winding process of the inductor coil is mainly achieved by a winding machine.

[0003] For example, the Chinese patent document with publication number CN218631654U discloses a winding device, including a wire hanging module and a wire pressing and rotating module; the wire hanging module includes a first screw module, a second screw module, a third screw module, a winding module and a wire clamping module; the winding module includes a winding motor, a driving wheel, a driven wheel, a winding needle and a belt; the wire clamping module includes a wire clamp and a motor; the wire pressing and rotating module includes a support block, a clamping fixture, a first winding motor and a second winding motor; a through groove is provided on the support block; the support block is in a "concave" shape; the first winding motor is arranged on one side of the support block; the second winding motor is arranged on the other side of the support block.

[0004] The technical solution in the above patent document also includes a wire pressing post and a wire pressing cylinder. After the first rotating chuck and the second rotating chuck simultaneously fix the magnetic core, one end of the copper wire is moved to the wire pressing post under the traction of the wire clamp and the winding needle and the copper wire is fixed before winding. When multi-layer winding is performed, the wire pressing post will fix multiple copper wires, which may easily lead to unstable fixation of the copper wires. Then the wire clamp and the winding needle will pull and wind the copper wire. The huge pulling force generated will further affect the fixation of the copper wire by the wire pressing post, causing the copper wire to loosen, resulting in the copper wire not being able to be tightly wound around the magnetic core, affecting the quality of the winding. Utility Model Content

[0005] The purpose of the utility model is to provide a magnetic winding clamping device to solve the problem that when the existing magnetic core is wound in multiple layers, the wire pressing posts simultaneously press the ends of the copper wires, which easily leads to unstable fixation of the copper wires and thus affects the winding quality.

[0006] To achieve the above-mentioned purpose, an embodiment of the present invention provides a magnetic winding wire clamping device for clamping the end of the wound magnetic ring and the wire; it includes a support seat, a magnetic ring clamp, a wire clamp and a wire shifting mechanism; the support seat is arranged on the turntable, the magnetic ring clamp is arranged on the support seat, and the end of the magnetic ring clamp is provided with a first clamping position, and the first clamping position is used to clamp the magnetic ring; the upper end of the support seat is also provided with a mounting seat, the wire clamp is arranged on the mounting seat, and the wire clamp includes a clamping claw, one end of the clamping claw is provided with a clamping portion extending downward, the clamping portion is located on the top side of the magnetic ring clamp, and forms a second clamping position with the top side of the magnetic ring clamp, and a gap is formed between the bottom side of the clamping claw and the top side of the magnetic ring clamp; the wire shifting mechanism includes a transverse mechanism and a shifting claw, the transverse mechanism is connected to the support seat, and the shifting claw is arranged on the transverse mechanism and extends into the gap.

[0007] Furthermore, the magnetic ring clamp includes a fixed clamp, a movable clamp and a driving member. The fixed clamp is arranged on the support seat, and the side wall of the fixed clamp extends upward to have a connecting position, and the movable clamp is pivotally connected to the connecting position; the driving member is connected to the movable clamp to drive the movable clamp to rotate around the pivot; the clamping portion and the top side of the movable clamp form the second clamping position.

[0008] Furthermore, a clamping groove is provided on the top side of the movable clamp, and a side of the clamping groove closer to the gap is an inclined surface.

[0009] Furthermore, the wire-digging mechanism is arranged on the movable clamp and rotates together with the movable clamp.

[0010] Furthermore, the wire-driving mechanism further includes a horizontal pushing mechanism, which is arranged on the movable clamp, and the transverse movement mechanism is arranged on the horizontal pushing mechanism, and the horizontal pushing mechanism is used to push the transverse movement mechanism to move forward and backward.

[0011] Furthermore, the horizontal push mechanism and the horizontal movement mechanism are both telescopic cylinders.

[0012] Furthermore, the wire clamp also includes a downward-pressing cylinder provided on the mounting seat, and the clamping claw is connected to the downward-pressing cylinder.

[0013] The above one or more technical solutions in the magnetic winding wire clamping device provided by the embodiment of the present invention have at least the following technical effects:

[0014] Because the first clamping position and the second clamping position are respectively located at the end and the top side of the magnetic ring clamp, the two clamping positions are adjacent to each other, which facilitates the rapid clamping and fixing of the wire after the magnetic ring is fixed and ensures the accuracy of the wire winding around the starting point of the magnetic ring.

[0015] Because a gap is formed between the bottom side of the clamp and the top side of the magnetic ring clamp, the traverse mechanism of the wire-moving mechanism is connected to the support base, and the traverse mechanism is provided on the traverse mechanism and extends into the gap. When the first wire completes winding around the magnetic ring, the traverse mechanism drives the traverse to move the end of the wire outside the clamp, facilitating the clamp's clamping portion to separately clamp and secure the end of the second wire to the top side of the magnetic ring clamp, thereby ensuring the stability of the second wire end and improving the winding quality. This prevents the clamp's clamping portion from simultaneously clamping the ends of two wires, which could easily cause the end of the second wire to loosen or even detach from the second clamping position during the winding process, resulting in the second wire being unable to be tightly wound around the magnetic ring and affecting the winding quality.

[0016] A magnetic winding machine comprises the magnetic winding clamping device.

[0017] The above one or more technical solutions in the magnetic winding machine provided by the embodiment of the present invention have at least the following technical effects:

[0018] When the magnetic ring completes winding of a wire, the wire-moving mechanism will move the end of the wire outside the wire clamp, and the wire clamp will then clamp and fix the end of the next wire separately, ensuring the clamping stability of the next wire and ensuring that the next wire can be tightly wound on the magnetic ring, thereby improving the winding quality.

[0033] In the embodiments of the present invention, unless otherwise expressly specified or limited, the terms "installed," "connected," "connected," "fixed," etc. should be understood in a broad sense. For example, they may refer to fixed connection, detachable connection, or integration; mechanical connection, electrical connection; direct connection, indirect connection through an intermediate medium; internal communication between two components, or interaction between two components. Those skilled in the art will understand the specific meanings of the above terms in the embodiments of the present invention based on specific circumstances.

[0034] In one embodiment of the magnetic winding machine of the present invention, please refer to Figures 1 to 3 The magnetic winding machine includes a magnetic winding clamping device 100. Specifically, when the magnetic ring 700 completes the winding of a wire, the wire-moving mechanism 500 will move the end of the wire to the outside of the wire clamp 400, and the wire clamp 400 will then clamp and fix the end of the next wire separately, ensuring the clamping stability of the next wire, ensuring that the next wire can be tightly wound on the magnetic ring 700, and improving the winding quality.

[0035] The magnetic ring winding clamping device 100 is used to clamp the winding magnetic ring 700 and the end of the wire. It includes a support base 200, a magnetic ring clamp 300, a wire clamp 400 and a wire dialing mechanism 500. The support base 200 is arranged on the turntable 600, and the magnetic ring clamp 300 is arranged on the support base 200. The end of the magnetic ring clamp 300 is provided with a first clamping position 310, and the first clamping position 310 is used to clamp the magnetic ring 700. The upper end of the support base 200 is also provided with a mounting base 210, and the wire clamp 400 is arranged on the mounting base 210. The wire clamp 400 includes a clamping claw 410, and one end of the clamping claw 410 is provided with a clamping portion 411 extending downward. The clamping portion 411 is located on the top side of the magnetic ring clamp 300 and forms a second clamping position 420 with the top side of the magnetic ring clamp 300. The bottom side of the clamping claw 410 forms a gap with the top side of the magnetic ring clamp 300. The wire shifting mechanism 500 includes a transverse movement mechanism 510 and a shifting claw 520 . The transverse movement mechanism 510 is connected to the support base 200 . The shifting claw 520 is disposed on the transverse movement mechanism 510 and extends into the gap.

[0036] Specifically, because the first clamping position 310 and the second clamping position 420 are respectively located at the end and the top side of the magnetic ring clamp 300, the two clamping positions are adjacent to each other, which facilitates the rapid clamping and fixing of the wire after the magnetic ring 700 is fixed, and ensures the accuracy of the wire winding at the starting point of the magnetic ring 700. Since a gap is formed between the bottom side of the clamping claw 410 and the top side of the magnetic ring clamp 300, the transverse movement mechanism 510 of the wire shifting mechanism is connected to the support seat 200, and the shifting claw 520 is provided on the transverse movement mechanism 510 and extends into the gap. When the first wire completes winding around the magnetic ring 700, the transverse movement mechanism 510 drives the shifting claw 520 to move the end of the wire to the outside of the wire clamp 400, so that the clamping portion 411 of the wire clamp can separately clamp and fix the end of the second wire to the top side of the magnetic ring clamp 300, thereby ensuring the stability of the end of the second wire and improving the winding quality. This prevents the clamping portion 411 of the wire clamp from clamping the ends of two wires at the same time, making the end of the second wire easily loose or even detached from the second clamping position during the winding process, resulting in the second wire being unable to be tightly wound around the magnetic ring, affecting the winding quality.

[0037] Furthermore, the magnetic ring clamp 300 includes a fixed clamp 320, a movable clamp 330, and a driving member 340. The fixed clamp 320 is disposed on the support base 200. The side wall of the fixed clamp 320 extends upward to form a connecting position 350, and the movable clamp 330 is pivotally connected to the connecting position 350. The driving member 340 is connected to the movable clamp 330 and is used to drive the movable clamp 300 to rotate about the pivot. The clamping portion 411 and the top side of the movable clamp 330 form a second clamping position 420. Specifically, because the movable clamp 330 is pivotally connected to the connecting position 350, the driving member 340 drives the movable clamp 330 to rotate up and down about the pivot, preventing the movable clamp 330 from deviating during rotation and affecting the clamping and stability of the magnetic ring 700.

[0038] Furthermore, the top side of the movable clamp 330 is provided with a clamping groove 331. The side of the clamping groove 331 closer to the gap is an inclined surface 332. Specifically, the clamping groove 311 cooperates with the clamping portion 411 of the clamping jaw, causing the end of the wire to tilt upward under the action of the clamping groove 311. Because the side of the clamping groove 311 closer to the gap is the inclined surface 332, the wire tilts and tilts within the gap, increasing the contact surface with the wire shifting mechanism 500 and ensuring that the wire can be moved by the wire shifting mechanism 500.

[0039] Furthermore, the wire-moving mechanism 500 is provided on the movable clamp 330 and rotates together with the movable clamp 330. Specifically, because the finger 520 of the wire-moving mechanism extends into the gap between the bottom side of the clamping jaw 410 and the top side of the magnetic ring clamp 300, the wire-moving mechanism 500 rotates together with the movable clamp 330, causing the finger 520 and the movable clamp 330 to rotate synchronously, thereby preventing the finger 520 from affecting the rotation angle of the movable clamp 330.

[0040] Furthermore, the wire-moving mechanism 500 also includes a horizontal push mechanism 530, which is disposed on the movable clamp 330. The transverse mechanism 510 is also disposed on the horizontal push mechanism 530. The horizontal push mechanism 530 is used to push the transverse mechanism 510 back and forth. Specifically, because the transverse mechanism 510 is provided with a pusher pawl 520, the horizontal push mechanism 530 pushes the transverse mechanism 510 and the pusher pawl 520 back and forth, causing the pusher pawl 520 to move into and out of the gap to avoid the wire clamp 400. Preferably, both the horizontal push mechanism 530 and the transverse mechanism 510 are telescopic cylinders, which have a simple structure and reliable movement.

[0041] Furthermore, the wire clamp 400 further includes a downward pressure cylinder 430 provided on the mounting base 210, and the clamping jaw 410 is connected to the downward pressure cylinder 430. Specifically, the downward pressure cylinder 430 drives the clamping jaw 410 to move up and down, so that the clamping jaw 410 can release the wire, making it easier for the wire-pulling mechanism 500 to move the wire.

[0042] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements and improvements made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
