Example Embodiment

[0027] Example 1

[0028] Such as Figure 3~4 As shown, a magnetic field-driven high-precision inductor processing device. First, a special equipment is used to process sector-shaped copper wire coils 1, and two semi-circular annular shells 2 are rotatable on the inner circumference. The semi-circular annular shells 2 are engaged by a joint 8. The copper wire The coil 1 is assembled on the housing 2, and the magnetic strip 4 is wound into the rotatable part of the housing 2 through the window 3, that is, the inner circumferential groove 5, and its structure is similar to a tape measure. By applying an external magnetic field 7 (such as figure 1 As shown, the axial section of the semicircular annular housing 2 is placed in the magnetic field 9), and is wound by the height-adjustable brush 10, the number of turns is controlled by the inductance testing equipment, and the inductance testing equipment is connected to the winding On a good copper wire coil 1, when the inductance reach...

[0031] Example 2

[0032] Such as Figure 5~6 As shown, a mechanically driven high-precision inductor processing device uses a sector-shaped copper wire coil 1 processed by special equipment. There are two special inner-peripheral rotatable shells 2. That is, the inner circumferential part of the shell 2 has a groove 5, the groove There is a ring gear 6 in 5, the ring gear 6 meshes with a pair of gears 7, the copper wire coil 1 is assembled on the housing 2, and the magnetic strip 4 is wound onto the rotatable part of the housing 2 through the window 3, usually by glue The process of fixing the ring gear 6 and then winding it through the gear 7, the number of turns is connected to the wound coil 1 by the instrument for testing inductance. When the inductance reaches the actual required value, the gear is controlled by program instructions 7 Stop the rotation and complete the winding of the inductor.

[0033] Since the copper wire coil 1 used in the same batch of inductors is proc...

Abstract

The invention discloses a processing device and method for a high-precision inductor. The method comprises the following steps: 1, winding a copper coil (1); 2, assembling the copper coil well wound in the step 1 with casings (2); 3, winding a magnetic core in the casings (2). Winding of a magnetic strip is controlled through a rotatable part in the casings (2), so that the rotatable part is matched with inductance measurement equipment, connected with the copper coil (1), to measure the inductance value, when the inductance value meets the requirement, the rotatable part is stopped, and production of the inductor is finished. Electrical parameters of the inductor have high consistency, meanwhile, use of an inductor with a large wire diameter is not dependent on manual operation any more, and the production efficiency and the product quality are improved greatly.

Description

technical field [0001] The invention relates to a processing method and device for ring inductors, especially a method and device capable of automatic processing while realizing precise control of inductance. The invention can be used for common mode inductors (double windings), differential mode inductors (single winding ) and ring transformer (multi-winding) processing. Background technique [0002] The processing of existing ring inductors mostly relies on manual and automatic winding machines to process and wind enameled wire coils, but the above-mentioned processing technology is powerless when faced with the processing of ring inductors with a wire diameter above 0.5mm, and cannot break through the size limit. On the other hand, considering the deviation of the finished product due to the processing technology and material of the magnetic material itself, usually about 20%, it is necessary to design a device that can automatically process high-precision ring inductors....
