Description

Technical Field

[0001] This invention belongs to the field of inductor winding technology, and particularly relates to an inductor winding device. Background Technology

[0002] Inductors are among the most common components in circuits, playing a crucial role. As circuit integration increases, inductors are becoming smaller and smaller. Among them, wire-wound inductors are increasingly widely used due to their miniaturization, high quality, high energy storage, and low resistance.

[0003] During the manufacturing process of inductors, a winding operation is required. In actual winding operations, the type of winding is often selected according to the actual usage requirements of the inductor. Currently, round wire or flat wire is often used to wind inductors to form corresponding round wire inductors or flat wire inductors.

[0004] In the winding process of a round wire inductor, a certain winding angle is required to form a spiral winding structure. However, in the winding process of a flat wire inductor, the winding operation can be performed directly on a horizontal plane without the need to form a winding angle.

[0005] Existing inductor winding equipment can only perform winding operations on a single type of round wire inductor or flat wire inductor, and cannot be compatible with winding operations of both types of inductors. Furthermore, the inductor winding process requires multiple steps such as winding and welding, and requires numerous operating mechanisms. Existing winding equipment suffers from defects such as low production efficiency, poor finished product stability, and low pass rate. Summary of the Invention

Detailed Implementation

[0044] The following drawings disclose several embodiments of the present invention. For clarity, many practical details will be described in the following description. However, it should be understood that these practical details are not intended to limit the invention. That is, in some embodiments of the invention, these practical details are not essential. Furthermore, for the sake of simplicity, some conventional structures and components will be shown in the drawings in a simple schematic manner.

[0045] Furthermore, in this invention, the use of terms such as "first" and "second" is for descriptive purposes only and does not specifically refer to any order or sequence, nor is it intended to limit the invention. They are merely used to distinguish components or operations described using the same technical terms, and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features. Therefore, a feature defined with "first" or "second" may explicitly or implicitly include at least one of those features. Additionally, the technical solutions of various embodiments can be combined with each other, but only if they are feasible for those skilled in the art. If a combination of technical solutions is contradictory or impossible to implement, such a combination should be considered nonexistent and not within the scope of protection claimed by this invention.

[0046] Combination Figure 1 and Figure 2 As shown, this embodiment provides an inductor winding device that winds a coil onto an inductor. The winding device 1 includes, in sequence, a coil tensioning assembly 10 for guiding the coil feed, a coil output assembly 20 for pulling out the coil, a winding assembly 30 for winding the coil, and a spot welding assembly 40 for welding the wound inductor. The coil tensioning assembly 10 guides the fed coil, then the coil output assembly 20 pulls out the coil, and the winding assembly 30 winds the coil onto the inductor. The spot welding assembly 40 then spot welds the wound inductor. Specifically:

[0047] like Figure 3As shown, the coil tensioning assembly 10 includes a tensioning lifting module 11 and a tensioning structure 12 that moves along the height direction of the tensioning lifting module 11. The tensioning structure 12 includes a tensioning moving block 121, a tensioning cylinder 122 located at the end of the tensioning moving block 121, and a tensioning push block 123 located at the piston rod end of the tensioning cylinder 122. A flat wire block 1211 is provided on the tensioning moving block 121, and a flat wire hole is provided on the flat wire block 1211 for the flat wire to pass through. A round wire block 1231 is provided on the tensioning push block 123. The coil tensioning assembly 10 of this embodiment is compatible with both flat wire inductor winding and round wire inductor winding, and has a round wire hole for the round wire to pass through. When the coil is a flat wire, the coil can pass through the flat wire hole of the flat wire block 1211 without adjusting the winding angle. When the coil is a round wire, the coil passes through the round wire hole of the round wire block 1231. The round wire block 1231 swings at an angle relative to the tensioning push block 123 to meet the winding requirements of the round wire. The coil tensioning assembly 10 of this embodiment is compatible with both flat wire inductor winding and round wire inductor winding, and has stronger applicability.

[0048] Specifically, the circular wire block 1231 is hinged to the tensioning push block 123. The circular wire block 1231 is an L-shaped structure. The longer end of the circular wire block 1231 is provided with an arc groove. The circular wire block 1231 swings along the arc direction of the arc groove. The circular wire hole is located at the shorter end of the circular wire block 1231. When the winding angle of the circular wire block 1231 is adjusted, it can be adjusted along the arc direction of the arc groove, thereby meeting the winding requirements of the circular wire.

[0049] Combination Figure 4 and Figure 5As shown, the coil feeding assembly 20 in this embodiment includes a feeding transfer module 21 and a feeding structure 22 that moves along the driving direction of the feeding transfer module 21. After the feeding structure 22 fixes the coil, the feeding transfer module 21 feeds the coil out. The feeding structure 22 includes a feeding mounting block 221, a feeding cylinder 222 located on the feeding mounting block 221, and a feeding pressure block 223 and a feeding cutter 224 located at the piston rod end of the feeding cylinder 222. A feeding stop block 2211 is provided at the end of the feeding mounting block 221. The feeding pressure block 223 presses the coil tightly, and the feeding cutter 224 cuts the coil simultaneously. During the coil feeding process, the feeding cylinder 222 drives the feeding pressure block 223 and the feeding cutter 224 to move. The coil is pressed together by the discharge pressure block 223 and the discharge stop block 2211. The front section of the coil is cut off by the discharge cutter 224 and the discharge stop block 2211. Then the discharge transfer module 21 drives the discharge structure 22 to move longitudinally and then laterally. The longitudinal movement can misalign the discharge structure 22 to facilitate the pull-out of the coil, while the lateral movement can pull out a coil of a fixed length. After the front end clamps the coil, the coil is released to proceed to the next discharge step. The coil discharge component 20 in this embodiment can stably discharge the coil. The discharge length of the coil is determined according to the actual winding requirements, which can ensure that the discharge length of each section of the coil is fixed, thereby ensuring the consistency of the product.

[0050] Combination Figure 6 and Figure 7 As shown, the winding assembly 30 in this embodiment includes a rotating stop post 31, a rotating winding clamp 32 located on one side of the rotating stop post 31, and a rotating collet 33 for clamping the inductor. The rotating winding clamp 32 clamps the coil and rotates circumferentially around the rotating stop post 31. The rotating collet 33 is located on the same straight line as the rotating stop post 31 and rotates synchronously with the rotating stop post 31. The inductor on the rotating collet 33 contacts the top surface of the rotating stop post 31. When the coil unloading assembly 20 pulls out the coil, the rotating winding assembly 30 rotates... The wire clamp 32 clamps the front end of the coil. After clamping, the rotating stop post 31 and the rotating collet 33 with the inductor rotate synchronously. The rotating winding clamp 32 clamps the coil and rotates it to wind the coil onto the inductor. During the winding process, the inductor on the rotating collet 33 contacts the top surface of the rotating stop post 31. When the coil is wound to the bottom of the inductor, the rotating stop post 31 can block the winding and prevent over-winding. The winding assembly 30 in this embodiment can accurately and stably wind the inductor.

[0051] Furthermore, the winding device 1 in this embodiment also includes a winding lifting module 50. The rotating stop column 31 is connected to the winding lifting module 50 through the winding bracket 51 and moves along the height direction of the winding lifting module 50. When the winding coil is a round wire, the winding lifting module 50 drives the rotating stop column 31 to move up and down through the winding bracket 51, so that the coil forms a spiral structure on the inductor, thereby meeting the winding requirements of the round wire inductor.

[0052] Combination Figure 8 and Figure 9 As shown, the spot welding assembly 40 in this embodiment includes a spot welding gripper 41 for positioning the inductor and a spot welding module 42 for spot welding the inductor. The rotating collet 33 moves the inductor onto the spot welding gripper 41, and the spot welding module 42 performs spot welding on the inductor. A spot welding head 43 and a spot welding cutter 44 are provided on the spot welding module 42. After the spot welding head 43 performs spot welding on the wound inductor, the spot welding cutter 44 cuts off the excess wire to facilitate the subsequent processing of the excess wire.

[0053] Furthermore, the winding device 1 in this embodiment also includes a feeding assembly 100, which is located at the spot welding gripper 41. The feeding assembly 100 includes a feeding lifting cylinder 101, an air blowing head 102 located at the piston rod end of the feeding lifting cylinder 101, and a feeding pipe 103 for feeding inductors. The air blowing head 102 blows the inductors on the spot welding gripper 41 into the feeding pipe 103. After the product is formed, the feeding lifting cylinder 101 lifts the air blowing head 102, and the air blowing head 102 blows the finished product into the feeding pipe 103, thus completing the feeding operation of the finished product.

[0054] like Figure 10 As shown, the winding device 1 in this embodiment also includes a collet transfer module 60. The rotating collet 33 is located on the collet transfer module 60 and moves along the driving direction of the collet transfer module 60. A cooperating gripper 61 is provided on one side of the rotating collet 33. The cooperating gripper 61 clamps the excess wire at the end of the inductor after winding. During the inductor feeding process and after winding is completed, the collet transfer module 60 can drive the collet to move and realize the transfer of the inductor. The presence of the cooperating gripper 61 can clamp the excess wire of the wound inductor, avoid interference between the excess wire and other structures, and ensure the processing effect of the product.

[0055] like Figure 2 As shown, the winding device 1 in this embodiment also includes

[0056] The coil feeding assembly 70 is connected to the coil tensioning assembly 10. The coil feeding assembly 70 feeds the coil using a feeding roller. The coil is tensioned by multiple tensioning rollers, guided by the coil tensioning assembly 10, and the coil discharge assembly 20 pulls the coil out.

[0057] Inductor feeding assembly 80 feeds inductors using a vibration feeding method.

[0058] like Figure 11 As shown, the inductor feeding assembly 80 in this embodiment is provided with a lifting platform 81 at its end. The lifting platform 81 is provided with a material slot 811 for accommodating inductors. The rotating collet 33 grabs the inductors in the material slot 811. A material platform cylinder 82 is provided below the lifting platform 81, which can drive the lifting platform 81 to move up and down. In this embodiment, the presence of the lifting platform 81 can buffer the incoming inductors and ensure the continuity of subsequent operations.

[0059] like Figure 12 As shown, the winding device 1 in this embodiment also includes a wire flipping assembly 90. The wire flipping assembly 90 includes a wire flipping module 91, a wire flipping cylinder 92 that moves along the driving direction of the wire flipping module 91, and a wire flipping gripper 93 located at the rotating end of the wire flipping cylinder 92. The wire flipping gripper 93 flips the excess wire at the end of the inductor. When the winding coil is a flat wire, the excess wire needs to be flipped after the winding is completed. At this time, the inductor after winding is located on the spot welding gripper 41. After the wire flipping assembly 90 flips the excess wire, the spot welding operation is performed.

[0060] In practical use, this embodiment is divided into two situations:

[0061] 1. When the winding coil is a flat wire

[0062] The flat wire is fed by the coil feeding assembly 70, and then pulled out by the coil output assembly 20 through the flat wire block 1211 of the coil tensioning assembly 10. After being pulled out, the winding assembly 30 winds the flat wire around the surface of the inductor, completing the initial winding operation. Then, the collet transfer module 60 transfers the wound inductor to the spot welding jaws 41 by rotating the collet 33. The spot welding jaws 41 hold the inductor. After holding, the wire flipping assembly 90 flips the excess wire on the inductor, completing the winding of the inductor. After the second winding operation, the spot welding module 42 of the spot welding assembly 40 drives the spot welding head 43 to spot weld the wound inductor. After spot welding, the spot welding cutter 44 is used to pre-cut the excess wire. After pre-cutting, the flipping claw 93 of the flipping assembly 90 clamps the excess wire, and the flipping module 91 drives the flipping claw 93 to pull the excess wire off, thus completing the spot welding and cutting operation of the wound inductor to form a finished product. Then, the air blowing head 102 of the unloading assembly 100 blows the finished product into the unloading pipe 103 for unloading.

[0063] II. When the winding coil is a round wire

[0064] The round wire is fed by the coil feeding assembly 70, and then pulled out by the coil output assembly 20 through the round wire block 1231 of the coil tensioning assembly 10. After being pulled out, the winding assembly 30 winds the round wire. During the winding process, the winding lifting module 50 drives the rotating stop column 31 of the winding assembly 30 to move vertically, so that the round wire forms a spiral structure on the inductor surface, completing the winding operation. Then, the collet transfer module 60 transfers the wound inductor to the spot welding clamp by rotating the collet 33. On the claw 41, the spot welding module 42 of the spot welding assembly 40 drives the spot welding head 43 to spot weld the wound inductor. After spot welding, the spot welding cutter 44 pre-cuts the excess wire. After pre-cutting, the flipping claw 93 of the flipping assembly 90 clamps the excess wire, and the flipping module 91 drives the flipping claw 93 to pull the excess wire off, completing the spot welding and cutting operation of the wound inductor to form a finished product. Then, the air blowing head 102 of the unloading assembly 100 blows the finished product into the unloading pipe 103, and the unloading is completed.

[0065] In summary, this invention provides an inductor winding device 1. A flat wire block 1211 and a round wire block 1231 are arranged on the coil tensioning assembly 10, enabling the winding device 1 to be applicable to both round and flat wire inductors, thus enhancing its applicability. Furthermore, this invention effectively performs winding and welding processes on inductors, resulting in high production efficiency and stable product quality. The presence of the winding lifting module 50 allows the winding assembly 30 to move vertically when the winding operation is for round wire, forming a spiral coil on the inductor, thus satisfying the winding operation for round wire inductors. When the winding operation is for flat wire, the winding lifting module 50 does not need to operate. The presence of the flipping assembly 90 allows the flat wire to be further flipped and attached to the inductor for welding when the winding operation is for flat wire. When the winding operation is for round wire, the flipping assembly 90 does not need to operate.
