Description

Technical Field

[0001] The invention belongs to the technical field of anchor rods, in particular to a continuous winding device for an annular magnetic core. Background Art

[0002] A magnetic core refers to a sintered magnetic metal oxide composed of a mixture of various iron oxides. In the production of annular magnetic cores, the annular magnetic cores need to be wound, which requires the use of an annular winding machine, which is a special equipment used to produce annular coils such as toroidal transformers, current transformers, and magnetic toroidal inductors.

[0003] A patent with publication number CN114360896B discloses a ring-shaped inductor winding device and a winding method thereof, including an operating table, wherein the upper surface of the operating table is provided with a fixing mechanism for assisting the winding of the equipment, the fixing mechanism is provided with a mounting mechanism for fixing the coil, the fixing mechanism is provided with a power mechanism for assisting the movement of the cable, and the groove formed by the circular fixing disk and the circular cover plate can be engaged with the inductor coil body to ensure the stability of the inductor coil body. After the fixing is completed, the first motor is started, and the rotation of the output shaft of the first motor drives the rotation of the friction sleeve, thereby driving the rotation of the inductor coil body. The device uses three first threaded rods that can be adjusted. By changing the position of the first threaded rods, the distance between the friction sleeves is changed, so that the equipment can fix inductor magnetic rings of different sizes and improve the range of inductance processing of the equipment.

[0004] There are still some problems in the actual application of the above scheme. In the process of winding the annular magnetic core, the annular rotating sleeve is driven by starting the second motor to drive the pay-off roller to pay out the wire. The pay-off roller will rotate during the process of winding the magnetic core, thereby performing the pay-off operation. However, because the annular rotating sleeve rotates at high speed during the winding process, after the winding is completed and an emergency stop is made, the pay-off roller connected to the inside of the annular rotating sleeve may continue to rotate for several circles due to the inertia of rotation, thereby continuing to pay out the wire. At this time, since there is no need to wind the wire anymore, it is necessary to reel in the excess copper wire that has been released. At the same time, the reeling of the copper wire is also unstable. Because the copper wire is metal, creases are prone to occur during the reeling process, resulting in low production quality of the copper wire.

[0005] To this end, the present invention provides a toroidal magnetic core continuous winding device. Summary of the invention

[0006] In order to make up for the deficiencies of the prior art, at least one technical problem raised in the background technology is solved.

[0009] A second motor is disposed on the upper surface of the base, and the second motor is used to drive the rotating ring to rotate;

[0010] The inner wall of the rotating ring is provided with a self-locking component, and the self-locking component can timely complete self-locking of the pay-off roller when the rotating ring stops suddenly, so as to prevent the pay-off roller from releasing excess wire due to inertial rotation;

[0011] An alarm component is provided on one side of the self-locking component, and the alarm component is used for automatically monitoring the remaining amount of the copper wire. Through the cooperation of the self-locking component and the alarm component, the copper wire pay-off status can be fed back in time during the winding process.

[0012] Preferably, the limiting assembly includes a sliding frame slidably connected to the two guide rails, a first motor is fixedly connected to the interior of the sliding frame, a rotating roller is fixedly connected to the output end of the first motor, and an auxiliary roller is slidably connected to each of the two guide rails. The magnetic ring is limited by the cooperation of the rotating roller and the two auxiliary rollers. At the same time, the first motor is started to drive the rotating roller to rotate, which can drive the magnetic ring to rotate, thereby winding the entire ring surface of the magnetic ring.

[0013] Preferably, the upper surfaces of the two auxiliary rollers are provided with coating components, and the coating components are used to coat glue on the surface of the wound copper wire, so that it can be more stably fixed on the magnetic ring after being wound on the magnetic ring.

[0015] Preferably, the cross-sections of both ends of the fixing plate are right-angled triangles. The setting of the triangles at the ends of the fixing plate can guide the winding of the copper wire, which not only automatically applies glue but also guides it, thereby improving the uniformity of the copper wire winding.

[0016] Preferably, the self-locking assembly includes a fixed groove body opened inside the rotating ring, a spring is fixedly connected to the inside of the fixed groove body, a fixed rod is fixedly connected to one end of the spring away from the fixed groove body, an insertion rod is fixedly connected to one end of the fixed rod away from the spring, and a plurality of insertion holes are opened at the end of the pay-off roller, and the insertion holes are used to insert the insertion rods.

[0017] Preferably, two connection frames are fixedly connected to the inner wall of the rotating ring, and a same connection shaft is fixedly connected inside the two connection frames by bolts, and a pay-off roller is rotatably connected to the circumferential surface of the connection shaft.

When the copper wire is wound down to the last layer, the spring sheet is perpendicular to the positioning plate, and at this time the spring sheet abuts against the abutment block. After the abutment, the spring sheet and the abutment block are energized, and the signal is transmitted to the system, an alarm is issued in time, and the rotating ring is stopped to replace the new wire-paying roller.

[0021] The beneficial effects of the present invention are as follows:

[0022] 1. The present invention discloses a continuous winding device for an annular magnetic core, which is connected to the pay-off roller by rotation through a rotating ring on one side of a fixed frame, so that the copper wire can be wound on the magnetic ring as the rotating ring rotates, wherein the second motor serves as a power source to drive the rotating ring to rotate at a set speed, thereby controlling the winding speed, and the self-locking component arranged on the inner wall of the rotating ring can respond quickly when the rotating ring stops suddenly, and self-lock the pay-off roller, thereby effectively preventing excessive release of the copper wire due to inertial rotation, and ensuring the stability of the winding quality, and at the same time, the alarm component on one side of the self-locking component can monitor the remaining amount of the copper wire in real time, and automatically trigger an alarm once the copper wire is close to being used up, reminding the operator to replace or replenish the copper wire in time, thereby avoiding winding interruption caused by insufficient copper wire, realizing continuous and stable winding of the annular magnetic core, and greatly improving production efficiency.

[0023] 2. The invention relates to a continuous winding device for an annular magnetic core, wherein the fast rotation of the rotating ring causes the fixed rod to slide out of the fixed groove body under the action of centrifugal force in an instant, and the fixed rod that slides out of the fixed groove body will pull the spring, and at the same time, the plug rod fixedly connected to one end of the fixed rod will disengage from the insertion hole, thereby unlocking the wire-releasing roller, and then the wire-releasing roller can self-rotate and wind and release the wire under the drive of the rotating ring. When the winding is completed and the rotating ring is closed, the rotating ring will stop immediately. At this time, the fixed rod loses centrifugal force, and the rebound force of the spring will drive the fixed rod to retract into the fixed groove body. At this time, the plug rod at one end of the fixed rod will immediately be inserted into the insertion hole again, achieving the effect of immediately self-locking the wire-releasing roller at the same time, preventing it from rotating several circles for wire-releasing under the action of inertia, resulting in excessive copper wire release, which increases the work for subsequent winding, and once the copper wire is released, it will cause certain damage to the copper wire through manual rewinding, thereby improving the winding accuracy.

[0038] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further explained below in conjunction with specific implementation methods. Embodiment 1

[0039] like Figures 1 to 7 As shown, a ring-shaped magnetic core continuous winding device described in an embodiment of the present invention includes a base 1, and two guide rails 2 are arranged on the upper surface of the base 1. Limiting components are slidably arranged on the two guide rails 2, and the limiting components are used to limit the magnetic ring 3; a fixing frame 4 is fixedly connected to the upper surface of the base 1, and a rotating ring 6 is rotatably connected to one side of the fixing frame 4, and a pay-off roller 61 is rotatably fixed inside the rotating ring 6; a second motor 5 is arranged on the upper surface of the base 1, and the second motor 5 is used to drive the rotating ring 6 to rotate; a self-locking component is arranged on the inner wall of the rotating ring 6, and the self-locking component can timely complete self-locking of the pay-off roller 61 when the rotating ring 6 stops suddenly, so as to prevent the pay-off roller 61 from releasing excess wire due to inertial rotation; an alarm component is arranged on one side of the self-locking component, and the alarm component is used to automatically monitor the remaining amount of copper wire. Through the cooperation of the self-locking component and the alarm component, the copper wire pay-off status can be fed back in time during the winding process.

[0040] Specifically, in the process of winding the annular magnetic core, the annular rotating sleeve is driven by starting the second motor 5 to drive the pay-off roller 61 to pay-off the wire. The pay-off roller 61 will rotate during the winding process of the magnetic ring 3, thereby performing the pay-off operation. However, because the annular rotating sleeve rotates at a high speed during the winding process, after the winding is completed and the emergency stop is performed, the pay-off roller 61 connected to the inside of the annular rotating sleeve may continue to rotate for several circles due to the inertia of rotation, thereby continuing to pay-off the wire. At this time, since no more winding is required, it is necessary to reel in the excess copper wire that has been released. At the same time, the reeling of the copper wire is also unstable. Because the copper wire is metal, creases are easily generated during the reeling process, resulting in the problem of low production quality of the copper wire.

[0041] Therefore, the present invention solves these two problems by setting a certain structure. First, the guide rail 2 and the limit assembly on the base 1 realize stable limiting of the magnetic ring 3, which can drive the magnetic ring 3 to rotate slowly during the winding process, thereby ensuring the accuracy and efficiency of the winding process. Then, the rotating ring 6 on one side of the fixed frame 4 is connected with the pay-off roller 61, so that the copper wire can be wound on the magnetic ring 3 as the rotating ring 6 rotates. The second motor 5 is used as a power source to drive the rotating ring 6 to rotate at a set speed, thereby controlling the winding speed. The self-locking assembly arranged on the inner wall of the rotating ring 6 can respond quickly when the rotating ring 6 stops suddenly, and self-lock the pay-off roller 61, effectively preventing the excessive release of copper wire due to inertial rotation, and ensuring the stability of the winding quality. At the same time, the alarm assembly on one side of the self-locking assembly can monitor the remaining amount of copper wire in real time. Once the copper wire is close to being exhausted, it will automatically trigger an alarm to remind the operator to replace or replenish the copper wire in time, avoiding the winding interruption caused by insufficient copper wire, and realizing continuous and stable winding of the annular magnetic core, thereby greatly improving the production efficiency.

[0042] The problem of excessive release of copper wire due to inertial rotation of the rotating ring 6 is solved, and the problem of the copper wire requiring the operator to always observe the amount of wire on the pay-off roller 61 is solved.

[0043] like Figure 1 As shown, the limiting assembly of this embodiment includes a sliding frame 21 slidably connected to the two guide rails 2, a first motor 22 is fixedly connected to the interior of the sliding frame 21, a rotating roller 23 is fixedly connected to the output end of the first motor 22, and an auxiliary roller 24 is also slidably connected to each of the two guide rails 2. The magnetic ring 3 is limited by the cooperation of the rotating roller 23 and the two auxiliary rollers 24. At the same time, the first motor 22 is started to drive the rotating roller 23 to rotate, which can drive the magnetic ring 3 to rotate, thereby winding the entire ring surface of the magnetic ring 3.

[0044] Specifically, the limiting component realizes flexible adjustment of the position of the magnetic ring 3 by sliding the sliding frame 21 on the two guide rails 2. First, the first motor 22 inside the sliding frame 21 is started to drive the rotating roller 23 to rotate, and an auxiliary roller 24 slidably connected to each of the two guide rails 2 cooperates with the rotating roller 23 to form a three-point limit for the magnetic ring 3, ensuring the stability of the magnetic ring 3 during the winding process. In addition, after starting the first motor 22, the rotation of the rotating roller 23 can drive the magnetic ring 3 to rotate slowly and synchronously, thereby realizing uniform winding of the entire ring surface of the magnetic ring 3. The setting of the limiting component not only improves the stability of the magnetic ring 3 during the winding process, but also realizes all-round limit of the magnetic ring 3 through the cooperation of the rotating roller 23 and the auxiliary roller 24, effectively preventing the magnetic ring 3 from deflecting or shaking during the winding process. At the same time, the driving mode of the first motor 22 makes the rotation speed of the magnetic ring 3 controllable, further improving the uniformity and quality of the winding, and improving the overall work efficiency.

[0045] like Figure 1 and Figure 3 As shown, the upper surfaces of the two auxiliary rollers 24 of this embodiment are provided with coating components, and the coating components are used to coat glue on the surface of the wound copper wire, so that it can be more stably fixed on the magnetic ring 3 after being wound on the magnetic ring 3.

[0046] Specifically, by providing a coating component on the two auxiliary rollers 24, glue can be evenly coated on the surface of the copper wire while it is wrapped around the magnetic ring 3. In this way, the wound copper wire can be more stably fixed on the magnetic ring 3 to prevent the winding effect from being affected by loosening or falling off. This not only improves the stability of the winding, but also simplifies the subsequent process of fixing the copper wire, thereby improving the overall production efficiency and product quality.

[0047] like Figure 4 As shown, the coating assembly of this embodiment includes a fixed plate 25 fixedly connected to the upper surface of the auxiliary roller 24, the fixed plate 25 and the auxiliary roller 24 are not directly fixed, the fixed plate 25 is fixedly connected to the outer shell above the auxiliary roller 24, the upper surface of the fixed plate 25 is fixedly connected to a storage box 26, a connecting pipe 29 is opened inside the fixed plate 25, one side of the fixed plate 25 is fixedly connected to a limiting plate 27, one side of the limiting plate 27 is rotatably connected to a plurality of rotating columns 28, a first cavity 210 is opened inside the limiting plate 27, and the glue in the storage box 26 flows into the first cavity 210 through the connecting pipe 29.

[0048] Specifically, the coating component is arranged on the winding path of the copper wire, so that the glue is cleverly coated on the copper wire. First, the fixed plate 25 is fixed to the outer shell to ensure the stable installation of the storage box 26 and the connecting pipe 29. Under the action of gravity, the glue in the storage box 26 flows into the first cavity 210 in the limit plate 27 through the connecting pipe 29. As the auxiliary roller 24 rotates, several rotating columns 28 roll in the first cavity 210 to evenly coat the glue on the copper wire, which not only realizes the continuous and uniform coating of the copper wire, but also avoids the waste and pollution caused by the glue dripping directly on the magnetic ring 3. At the same time, the rolling method of the rotating column 28 also ensures the uniformity and stability of the glue coating, thereby improving the coating efficiency.

[0049] like Figure 4 As shown, the cross-sections at both ends of the fixing plate 25 of this embodiment are right-angled triangles. The setting of the triangles at the ends of the fixing plate 25 can guide the winding of the copper wire, which not only automatically applies glue but also guides it, thereby improving the uniformity of the copper wire winding.

[0050] Specifically, the two ends of the fixing plate 25 are designed to have right-angled triangular cross-sections, which can play a guiding role when the copper wire is wound. The copper wire can automatically align with the central axis of the magnetic ring 3 during the winding process to prevent the deviation of the winding due to the angle of the wire release. At the same time, the uniform glue coating from the coating component and the setting of the fixing plate 25 can not only improve the uniformity of the winding, but also better fix the copper wire coated with glue on the magnetic ring 3. Embodiment 2

[0051] like Figures 1 to 7 As shown, compared with Example 1, another embodiment of the present invention is: the self-locking component includes a fixed groove body 65 opened inside the rotating ring 6, a spring 67 is fixedly connected to the inside of the fixed groove body 65, a fixed rod 68 is fixedly connected to the end of the spring 67 away from the fixed groove body 65, and an insertion rod 610 is fixedly connected to the end of the fixed rod 68 away from the spring 67, and a plurality of insertion holes 69 are opened at the end of the wire-releasing roller 61, and the insertion holes 69 are used to insert the insertion rod 610.

[0052] Specifically, when the second motor 5 drives the rotating ring 6 to rotate, the rapid rotation of the rotating ring 6 will cause the fixing rod 68 to slide out of the fixing groove 65 under the action of centrifugal force in an instant, and the fixing rod 68 that slides out of the fixing groove 65 will pull the spring 67, and at the same time, the plug rod 610 fixed to one end of the fixing rod 68 will be separated from the plug hole 69, thereby unlocking the wire-releasing roller 61, and then the wire-releasing roller 61 can rotate and release the wire under the drive of the rotating ring 6. When the winding is completed, the rotating ring 6 is turned off, and the rotating ring 6 will stop immediately. At this time, the fixing rod 68 loses the centrifugal force, and the resilience of the spring 67 will drive the fixing rod 68 to retract into the fixing groove 65. At this time, the insertion rod 610 at one end of the fixing rod 68 will also be immediately inserted into the insertion hole 69 again, achieving the effect of immediately self-locking the wire-releasing roller 61, preventing it from rotating several circles for wire-releasing under the action of inertia, resulting in excessive copper wire being released, which increases the work of subsequent winding. Once the copper wire is released, it will cause certain damage to the copper wire through manual rewinding, thereby improving the winding accuracy.

[0053] like Figure 4 As shown, in this embodiment, two connection frames 62 are fixedly connected to the inner wall of the rotating ring 6, and the same connection shaft 64 is fixedly connected in the two connection frames 62 by bolts 63. The circumferential surface of the connection shaft 64 is rotatably connected to the pay-off roller 61.

[0054] Specifically, a connecting frame 62 is fixed to the inner wall of the rotating ring 6, and then the bolts 63 in the two fixed frames are rotated, and then the two ends of the connecting shaft 64 in the middle of the pay-off roller 61 are fixed between the two bolts 63, and then the bolts 63 are rotated again to fix the pay-off roller 61 to the rotating ring 6 for subsequent winding work.

[0055] like Figure 5As shown, in this embodiment, a telescopic rod 66 is fixedly connected in the fixed groove body 65, and a spring 67 is sleeved on the circumferential surface of the telescopic rod 66. The telescopic rod 66 is used to limit the spring 67 to prevent the spring 67 from deforming in any direction other than the longitudinal direction.

[0056] Specifically, the telescopic rod 66 is fixedly connected to the fixed groove body 65, and the spring 67 is sleeved thereon. The deformation direction of the spring 67 is limited by the circumferential surface of the telescopic rod 66 to ensure that the spring 67 only expands and contracts in the longitudinal direction, avoiding twisting or bending in other directions, thereby improving the working stability and service life of the spring 67.

[0057] like Figure 5 As shown, the alarm assembly of this embodiment includes a spring piece 611 fixedly connected to one side of the fixed rod 68. The spring piece 611 will bend when it abuts against the copper wire. When the copper wire gradually decreases, the spring piece 611 will gradually return to its original position. A positioning plate 612 is fixedly connected to one side of the inner wall of the rotating ring 6, and an abutment block 613 is fixedly connected to one side of the positioning plate 612.

[0058] Specifically, the alarm component realizes the alarm function by the interaction between the spring piece 611 fixed on one side of the fixed rod 68 and the copper wire. When the copper wire exists, the spring piece 611 bends due to the squeezing force of the copper wire; as the copper wire gradually decreases, the pressure on the spring piece 611 gradually decreases, and it gradually resets. At the same time, the positioning plate 612 fixed on one side of the inner wall of the rotating ring 6 and the abutment block 613 thereon, when the rotating ring 6 rotates, the fixed rod 68 will abut against the positioning plate 612. When the spring piece 611 is reset to a certain extent, it contacts therewith and sends out an alarm signal, indicating that the copper wire has been reduced to the warning level. The reduction of the copper wire can be detected in real time, and the alarm is realized through the reset of the spring piece 611 and the contact of the abutment block 613.

[0059] like Figure 5 As shown, in this embodiment, when the rotating ring 6 rotates at high speed for winding, the spring 67 is stretched under the centrifugal force, and the insertion rod 610 is pushed out of the insertion hole 69, thereby releasing the wire-releasing roller 61. At the same time, when the fixing rod 68 abuts against the positioning plate 612, the spring piece 611 does not abut against the abutment block 613 because the spring piece 611 is deformed under the limitation of the copper wire. When the copper wire is wound down to the last layer, the spring piece 611 is perpendicular to the positioning plate 612. At this time, the spring piece 611 abuts against the abutment block 613. After the abutment, the spring piece 611 and the abutment block 613 are energized, and the signal is transmitted to the system, an alarm is issued in time, and the rotating ring 6 is stopped to replace the new wire-releasing roller 61.

[0060] Specifically, when the rotating ring 6 rotates at a high speed to perform the winding operation, the spring 67 in the fixed groove 65 is stretched due to the centrifugal force, and this stretching action pushes the insertion rod 610 out of its insertion hole 69 position, thereby smoothly releasing the wire-releasing roller 61, so that the copper wire can be wound freely. During this process, if the fixed rod 68 contacts the positioning plate 612, the spring piece 611 will not immediately contact the abutment block 613 because the spring piece 611 is physically restricted by the copper wire and deformed, maintaining a certain interval.

[0061] As the copper wire continues to wind and gradually descends to the last layer close to the pay-off roller 61, the position change of the copper wire no longer restricts the spring 611, so the spring 611 can return to its original state and gradually form a vertical posture with the positioning plate 612. At this critical moment, the spring 611 just contacts the abutment block 613. This contact action triggers the electrical connection, so that a path is formed between the spring 611 and the abutment block 613, thereby sending an electrical signal to the system.

[0062] After receiving this signal, the system can quickly identify that the copper wire is close to being wound, and immediately trigger an alarm, while taking measures to stop the rotation of the rotating ring 6. This series of responses is intended to ensure that the operator can promptly learn the need to replace the new pay-off roller 61 and take corresponding replacement operations, thereby avoiding production interruptions or copper wire winding chaos and other problems.

[0063] Working principle: first, through the guide rails 2 and the limit assembly on the base 1, the sliding frame 21 slides on the two guide rails 2 to achieve flexible adjustment of the position of the magnetic ring 3. First, the first motor 22 inside the sliding frame 21 is started to drive the rotating roller 23 to rotate, and an auxiliary roller 24 slidably connected to each of the two guide rails 2 cooperates with the rotating roller 23 to form a three-point limit for the magnetic ring 3, ensuring the stability of the magnetic ring 3 during the winding process. In addition, after starting the first motor 22, the rotation of the rotating roller 23 can drive the magnetic ring 3 to rotate synchronously and slowly, thereby achieving uniform winding of the entire ring surface of the magnetic ring 3. The setting of the limit assembly not only improves the stability of the magnetic ring 3 during the winding process, but also achieves all-round limit of the magnetic ring 3 through the cooperation of the rotating roller 23 and the auxiliary roller 24.

[0064] Then, the rotating ring 6 on one side of the fixed frame 4 is connected with the rotation of the pay-off roller 61, so that the copper wire can be wound on the magnetic ring 3 as the rotating ring 6 rotates, wherein the second motor 5 serves as a power source to drive the rotating ring 6 to rotate at a set speed. When the second motor 5 drives the rotating ring 6 to rotate, the spring 67 in the fixed groove 65 is stretched due to the centrifugal force, and this stretching action pushes the insertion rod 610 out of its insertion hole 69 position, thereby smoothly releasing the pay-off roller 61, so that the copper wire can be freely wound. During this process, if the fixed rod 68 contacts the positioning plate 612, the spring 611 will not immediately contact the abutment block 613 because the spring 611 is deformed by the physical restriction of the copper wire and maintains a certain interval.

[0065] As the copper wire continues to wind and gradually descends to the last layer close to the pay-off roller 61, the position change of the copper wire no longer restricts the spring 611, so the spring 611 can return to its original state and gradually form a vertical posture with the positioning plate 612. At this critical moment, the spring 611 just contacts the abutment block 613. This contact action triggers the electrical connection, so that a path is formed between the spring 611 and the abutment block 613, thereby sending an electrical signal to the system.

[0066] After receiving this signal, the system can quickly identify that the copper wire is close to being wound, and immediately trigger an alarm, while taking measures to stop the rotation of the rotating ring 6.
