Description

Technical Field

[0001] The invention belongs to the technical field of inductor manufacturing, and in particular relates to an inductor with good insulation effect and a manufacturing method thereof. Background Art

[0002] As a common electronic component, the inductor is mainly made of a spiral wire wound around a magnetic core and wrapped in an insulating shell. When current passes through the inductor, a magnetic field is generated, and an induced current is generated in the coil to hinder the change of current. Inductors are frequently used in many fields such as power electronic equipment, communication systems, and communication equipment.

[0003] Wire-wound inductors are the most basic and widely used inductors. The main structure of a wire-wound inductor is a metal core with a spiral wire wrapped around the core. The existing manufacturing equipment for wire-wound inductors has the following shortcomings:

[0004] 1. Existing manufacturing equipment for wound inductors cannot wrap metal cores of different diameters when wrapping wires around metal cores. When the size of the core changes, the device cannot make targeted adjustments to adapt to the problem of unstable fixation caused by changes in the core diameter.

[0005] 2. The existing manufacturing equipment for wound inductors has poor overall linkage when wrapping wires around metal cores. When processing the wires for winding, the wires are spirally mechanically deformed in batches before being matched with the metal cores. The problem caused by this operation is that when the wires are sleeved, the deformation of the wires needs to be strictly guaranteed to be stable, which often causes the metal core and the winding wire to not match.

[0006] 3. The existing wires used for inductor production are basically copper wires. After long-term stacking, the copper wires produced in batches will have an oxide layer and dirt on their outer surfaces due to oxidation and the influence of impurities in the environment, which will have a certain impact on the production of inductors. When winding the wires, the existing devices do not consider the synchronous cleaning of the wires to ensure the product stability of the inductors. Summary of the invention

[0007] In order to overcome the above defects, the present invention provides an inductor with good insulation effect and a manufacturing method thereof, which solves the problems in the prior art.

The combined sliding plate is provided with positioning bolts matching the arc-shaped through grooves, and the positioning bolts on the combined sliding plate are slidably connected to the arc-shaped through grooves on the corresponding side. An electric telescopic rod is fixedly connected to the clamping plate, and the output end of the electric telescopic rod is fixedly connected to the combined sliding plate on the corresponding side.

[0017] As a further solution of the present invention: the cooperative winding mechanism includes a positioning block, a second pulley, a transmission belt, a threaded rod, a limiting slide rod and a combined slide seat, the positioning block is fixedly connected to one side of the U-shaped seat, the second pulley is rotatably connected to one side of the positioning block, the transmission belt is sleeved between the first transmission belt and the second transmission belt, the threaded rod is rotatably connected in the U-shaped seat, the limiting slide rod is fixedly connected in the U-shaped seat, the combined slide seat is slidably connected to the limiting slide rod, and the combined slide seat is threadedly connected to the threaded rod.

[0050] When the wound copper wire 4 continuously moves from the combined slide 27 as the metal magnetic core 5 rotates, friction will continuously be generated between the wound copper wire 4 and the grinding sand ring 29. The grinding sand ring 29 can remove the oxide layer and impurities that may exist on the wound copper wire 4, thereby ensuring the quality of the wound copper wire 4. It should be noted that with the movement of the combined slide 27, the linkage gear 32 on the combined slide 27 will rotate under the action of the linkage tooth plate 33. Through the connection between the active pulley 31 and the passive pulley 30, the grinding sand ring 29 coaxially fixedly connected to the passive pulley 30 can rotate, thereby further improving the grinding efficiency.
