Problems solved by technology

like figure 1 , figure 2 As shown, the preparation of the toroidal skeleton coil adopts the toroidal winding principle. First, according to the calculation results, a toroidal skeleton 1 is prepared, and then the wound wire 2 is wound around the skeleton on the skeleton 1 by hand or machine winding. The method can complete the winding work of the coil better, but the diameter of the wound wire should not be too small, otherwise it is easy to cause the common problems of the ring winding method such as broken wires and knots. At the same time, due to human factors or machine precision, etc., Coils wound in this way have poor consistency

Embodiment Construction

[0020] In order to make the purpose, technical solutions and advantages of the present invention clearer, the implementation of the present invention will be further described in detail below in conjunction with the accompanying drawings:

[0021] This embodiment provides a winding method of a ring-shaped bobbin coil, such as image 3 As shown, the method mainly includes:

[0022] Step 10: Parallel winding on the straight strip-shaped skeleton;

[0023] Step 20 performs ring-shaped correction on the coils wound in parallel;

[0024] Step 30 cures the shaped toroidal coil.

[0025] Described also includes a step before carrying out step 10, skeleton blanking step: as Figure 4 As shown, according to the design requirements, the length l and cross-sectional area s of the skeleton 1 are calculated, and appropriate materials are selected, and a certain margin Δl is reserved on the basis of the calculated length l, and the skeleton 1 is l'=l+Δl The length of blanking.

Abstract

The invention discloses a method for winding a circular frame coil; the method mainly comprises the steps as follows: cutting off and straightening a circular frame, and paralleling a winding to a straight long strip shape frame; carrying out circular shape righting to the parallel winded coil; and curing the shape-righting circular coil. The method has simple process and high production efficiency, and is not easy to generate common adverse issues which appear in circular winding methods such as line broken, knot tied, and the like; and the winded coils are arranged closely and uniformly, therefore, the method is especially suitable for industrial mass production.

Description

technical field [0001] The invention relates to a winding method of a coil, in particular to a winding method of an annular skeleton coil. Background technique [0002] With the vigorous development of international electronic technology, the demand for various coils is increasing, and at the same time, higher requirements are placed on the precision of the coils. The toroidal bobbin coil is a hollow solenoid that is evenly and densely wound on the toroidal (magnetic / non-magnetic) bobbin. It is widely used in choke filtering, magnetic position measurement, transformer, current mutual inductance measurement and other fields. Typical toroidal bobbin coils are Rogowski Coils. [0003] In a nutshell, whether domestic or foreign, coil winding principles can be roughly divided into two types: parallel winding and circular winding. Among them, if the winding frame is rotated and the winding wire is translated to complete the winding, it is regarded as parallel winding, and on the...
