Abstract

The application discloses a self-winding annular inductor winding device and a winding method, and belongs to the technical field of annular inductors. In order to solve the problem that the uniformity of annular inductor winding is poor due to the blocking of the clamping assembly of the annular inductor, the complex and changeable movement direction of the winding mechanism, and the fact that the clamping position on the surface of the annular inductor cannot be wound, the single winding of the coil has obvious gaps. The four groups of driving gears of the application are used to alternately drive the arc-shaped matching bars to slide, the splicing end penetrates the inner side of the annular inductor, and the winding of the annular inductor wire body is realized. The arc-shaped matching bars are rotated multiple times and penetrate the inner side of the annular inductor multiple times, and the rotation of the annular inductor is matched, so that the wire body is uniformly wound on the surface of the annular inductor. After the annular inductor is unidirectionally rotated for one round, the winding operation of the annular inductor is realized, and the annular inductor is convenient for mass processing.

Description

Technical Field

[0001] This invention relates to the field of toroidal inductor technology, and in particular to a toroidal inductor winding device and method that can spontaneously wind toroidal inductors. Background Technology

[0002] A toroidal coil inductor is an electronic component mainly composed of a toroidal magnetic core. A soft magnetic inductor is an electronic component that primarily consists of a toroidal magnetic core around which wires made of iron powder, ferrite, or other materials are wound to form a horn inductor. Longitudinal field coils are used in a wide range of applications, such as high-frequency coils and transformers. Soft magnetic inductors can have a higher inductance factor and a higher inductance than electromagnetic coils of the same type. A toroidal coil inductor is formed by winding wires of material around the surface of a toroidal magnetic core.

[0003] However, existing technologies for winding coils in toroidal inductors involve clamping and fixing them, and then installing a winding mechanism on their outer side. This winding mechanism itself needs to perform circular motion, making the winding operation quite cumbersome. At the same time, due to the obstruction of the clamping components of the toroidal inductor, the movement direction of the winding mechanism is complex and variable, resulting in a lack of uniformity in the winding of the toroidal inductor coil. Furthermore, if the clamping position on the surface of the toroidal inductor cannot be used for coil winding, then each winding of the coil will have obvious gaps.

[0004] To address the above problems, improvements were made to the existing device, and a self-winding toroidal inductor winding device and winding method were proposed. Summary of the Invention

[0016] Another technical solution proposed by this invention: a winding method for a self-winding toroidal inductor winding device, comprising the following steps:

[0017] S1: The to-be-wound ring inductor is placed on the outside of the central rotating column, and its edge end is fitted between the sliding docking rod and the vertical bar. The protective pad is used for anti-wear protection. By controlling the swing of the swinging push rod, a squeezing force is applied to the sliding docking rod. The vertical bar and the sliding docking rod clamp the edge end of the ring inductor.

[0018] S2: The arc-shaped matching bar slides along the inner side of the fixed ring, causing the four sets of drive gears to alternately drive the arc-shaped matching bar to slide. One end of the toroidal inductor passes through the opening slot, and then the splicing end passes through the inner side of the toroidal inductor. The wire coil end is in a continuous unwinding state. After the arc-shaped matching bar passes through the toroidal inductor as a whole, the wire coil end wraps around the surface of the toroidal inductor, thereby realizing one-round winding of the toroidal inductor wire.

[0019] S3: Start the drive guide rod, which drives the toroidal inductor to rotate around the drive guide rod as the axis. Through the multiple rotations of the arc-shaped matching bar and its multiple passes through the inner side of the toroidal inductor, combined with the rotation of the toroidal inductor itself, the wire is evenly wound on the surface of the toroidal inductor.

[0020] S4: When the remaining thread of the wire coil is used up, when replacing the new splicing clip, press the pressing rod, squeeze the control piece to slide to the bottom of the reserved sliding inner cavity, move the adjusting rod to maintain the initial state, and then drive the piece to make the inner rod smoothly insert into the inner side of the matching slot.

[0021] S5: Release the pressing rod, the squeezing control piece moves back quickly along the reserved sliding inner cavity, one end of the movable adjusting rod passes through the lifting sliding cavity and corresponds to the matching slot, and the movable adjusting rod engages with the locking notch. At this point, all implementation steps are completed.

[0022] Compared with the prior art, the beneficial effects of the present invention are:

[0023] 1. This invention proposes a self-winding toroidal inductor winding device and method. By controlling the swing of the swinging push rod, the vertical bar and sliding docking rod clamp the edge end of the toroidal inductor. The toroidal inductor to be wound enters the inner side of the receiving side slot, and one side end of it corresponds to the side slot. Because the length of the arc-shaped matching bar is greater than the inner arc circumference of the two sets of drive gears, the four sets of drive gears alternately drive the arc-shaped matching bar to slide. The splicing end passes through the inner side of the toroidal inductor, thereby realizing one round of winding of the toroidal inductor wire. Through multiple rotations of the arc-shaped matching bar and multiple passes through the inner side of the toroidal inductor, combined with the rotation of the toroidal inductor itself, the wire is evenly wound on the surface of the toroidal inductor. After the toroidal inductor rotates once in one direction, the winding operation of the toroidal inductor can be realized, which is convenient for mass production of toroidal inductors.

[0024] 2. The present invention proposes a self-winding toroidal inductor winding device and method. When the remaining wire of the coil is exhausted, and a new splicing clip is replaced, the pressing rod is pressed, and the squeezing control slides to the bottom of the reserved sliding inner cavity. The movable adjusting rod separates from the interior of the matching slot, and then the plate is driven to smoothly insert the inner rod into the inner side of the matching slot. Then the pressing rod is released, and the squeezing control squeezes the movable adjusting rod. One end of the movable adjusting rod passes through the lifting sliding cavity and corresponds to the matching slot. The movable adjusting rod also engages with the locking notch, thereby completing the replacement of the splicing clip and realizing the winding operation of a new batch of toroidal inductors.

Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0037] Please see Figures 1-10 To address the technical problem that the winding mechanism's movement direction is complex and variable due to the obstruction of the toroidal inductor's clamping components, resulting in insufficient uniformity of the toroidal inductor coil winding and the inability to wind the coil at the clamping positions on the toroidal inductor surface, thus causing significant gaps in the single winding of the coil, the following preferred technical solution is provided:

The four sets of drive gears 77 mesh with the outer surface of the arc-shaped matching bar 73. The length of the arc-shaped matching bar 73 is greater than the distance between the two sets of drive gears 77.

[0040] The upper surface of the extended splicing channel 3 is provided with a pushing open long groove 31, and the inner bottom surface of the pushing open long groove 31 is provided with a displacement long groove 32. A drive screw 33 is installed inside the displacement long groove 32. The sliding block 4 includes a sliding base 41 connected to the bottom end of the central rotating column 51 and a sliding bottom block 42 installed on the lower surface of the sliding base 41. The sliding base 41 matches the pushing open long groove 31, and the sliding bottom block 42 matches the displacement long groove 32. The sliding bottom block 42 is sleeved on the surface of the drive screw 33. The side surface of the sliding docking column 55 is provided with a vertical side-opening guide groove 551, and a T-shaped limiting block 552 is provided inside the vertical side-opening guide groove 551. A movable connector 553 is installed on the outer surface. One end of the swing push rod 56 is connected to the movable connector 553. Both sides of the other end of the swing push rod 56 are provided with a sleeve gear disk 5322. A sleeve shaft 5321 is provided on the inner side of the swing open groove 532. The swing push rod 56 and the sleeve gear disk 5322 are both sleeved on the surface of the sleeve shaft 5321. A drive gear 5323 is provided on one side of the sleeve gear disk 5322. The sleeve gear disk 5322 is meshed with the drive gear 5323. Both ends of the lower surface of the anti-tipping splicing slider 58 are provided with anti-slip parts 581.

[0041] Specifically, the to-be-wound annular inductor is sleeved on the outside of the central rotating column 51, with its edge end fitted between the sliding docking rod 55 and the vertical bar 54. A protective pad 57 is used for wear protection. The drive gear 5323 is activated, causing the sleeved gear disk 5322 to swing. Utilizing the mobility of both ends of the swinging push rod 56, the swinging of the push rod 56 is controlled to apply a compressive force to the sliding docking rod 55. The sliding docking rod 55 slides along the sliding groove 531 via the anti-tipping splicing slider 58. The vertical bar 54... 4. The sliding docking rod 55 clamps the edge end of the toroidal inductor. Then, the drive screw 33 is activated, and the sliding base 42 slides along the shifting long groove 32. The sliding base 41 slides along the pushing open long groove 31, and the sliding base 41 drives the rotating clamping part 5 to slide towards the inside of the receiving side slot 2. The toroidal inductor to be wound enters the inside of the receiving side slot 2, and one end of it aligns with the side opening slot 6. The drive gear 77 is activated, and the meshing connection between the drive gear 77 and the outer surface of the arc-shaped matching bar 73 makes the arc-shaped matching bar 73... The bar 73 slides along the inner side of the fixed ring 71. Because the length of the arc-shaped matching bar 73 is greater than the inner arc circumference of the two sets of drive gears 77, the four sets of drive gears 77 alternately drive the arc-shaped matching bar 73 to slide. One end of the ring inductor passes through the opening slot 72, and then the splicing end 74 passes through the inner side of the ring inductor. When the arc-shaped matching bar 73 rotates, the first connecting block 75 and the second connecting block 76 gradually separate.

At the same time, the drive guide rod 52 is activated, causing the toroidal inductor to rotate around the drive guide rod 52 as the axis. Through multiple rotations of the arc-shaped matching bar 73 and multiple passes through the inner side of the toroidal inductor, combined with the rotation of the toroidal inductor itself, the wire is evenly wound on the surface of the toroidal inductor. After the toroidal inductor rotates one round in one direction, the winding operation of the toroidal inductor can be completed, which is convenient for mass production of toroidal inductors.

A wire reel end 765 is installed on the surface of the wire reel body 764. The end of the wire reel end 765 passes through... The outlet slot 762 is connected to the side surface of the splicing clip 752. The splicing clip 752 includes a piece 7521 corresponding to the positioning splicing block 751 and an inner rod 7522 installed on the inner surface of the piece 7521. There are two sets of inner rods 7522. The inner side of the inner rod 7522 is provided with a locking notch 7523. The pressing locking member 753 includes a pressing rod 7531 and a pressing control member 7532 installed at one end of the pressing rod 7531. Movable adjusting rods 7533 are provided on both sides of the pressing rod 7531. One end of the movable adjusting rod 7533 is connected to the locking notch 7523.

[0044] The positioning splicing block 751 has a reserved sliding inner cavity 7511 inside, which matches the extrusion control component 7532. Both the upper and lower surfaces of the reserved sliding inner cavity 7511 have lifting sliding chambers 7512, which match the movable adjustment rod 7533. The bottom end of the lifting sliding chamber 7512 has a matching slot 7513, which matches the inner rod 7522. The side surface of the positioning splicing block 751 has an outer through groove 7514, which matches the pressing rod 7531. Both side walls of the outer through groove 7514 have side-opening inner grooves 7515. Both side walls of the lifting sliding chamber 7512 have lifting side opening grooves 75121, and the first set of connecting sliding rods 75122 is installed inside the lifting side opening grooves 75121. Both sides of the rod 7533 are provided with a first connecting slider 75123, which is fitted onto the surface of the first connecting slide rod 75122.

[0045] Specifically, when the remaining thread in the wire reel 764 is exhausted, and a new splicing clip 752 is replaced, the pressing rod 7531 is pressed, causing the control piece 7532 to slide to the bottom of the reserved sliding inner cavity 7511. Utilizing the elastic structure of the first connecting spring 75124, the movable adjusting rod 7533 remains in its initial state, separating from the interior of the matching slot 7513. Then, the piece 7521 is moved to smoothly insert the inner rod 7522 into the inner side of the matching slot 7513. Finally, the pressing rod is released. The pressing rod 7531 utilizes the elastic structure of the second sleeve spring 75313 to cause the pressing control member 7532 to quickly move back along the reserved sliding inner cavity 7511, causing the pressing control member 7532 to press the movable adjusting rod 7533. One end of the movable adjusting rod 7533 passes through the lifting sliding cavity 7512 and corresponds to the matching slot 7513. The movable adjusting rod 7533 also engages with the locking notch 7523, thereby completing the replacement of the splicing locking piece 752 and realizing the winding operation of a new batch of toroidal inductors.

[0046] To further illustrate the above embodiments, the present invention also provides an implementation method for a self-winding toroidal inductor winding device, comprising the following steps:

[0047] Step 1: Place the ring-shaped inductor to be wound on the outside of the central rotating column 51, and let its edge end fit between the sliding docking rod 55 and the vertical bar 54. Protect it from wear by the protective pad 57. By controlling the swing of the swinging push rod 56, apply a squeezing force to the sliding docking rod 55. The vertical bar 54 and the sliding docking rod 55 clamp the edge end of the ring-shaped inductor.

[0048] Step 2: The arc-shaped matching bar 73 slides along the inner side of the fixed ring 71, causing the four sets of drive gears 77 to alternately drive the arc-shaped matching bar 73 to slide. One end of the toroidal inductor passes through the opening slot 72, and then the splicing end 74 passes through the inner side of the toroidal inductor. The wire coil end 765 is in a continuous unwinding state. After the arc-shaped matching bar 73 passes through the toroidal inductor as a whole, the wire coil end 765 wraps around the surface of the toroidal inductor, thereby realizing one-round winding of the toroidal inductor wire.

[0049] Step 3: Start the drive guide rod 52, which drives the toroidal inductor to rotate around the drive guide rod 52 as the axis.
