Embodiment Construction

[0030] Such as figure 1 As shown, a miniature transformer coil bobbin fixing device includes a shaft body, the shaft body is divided into upper, middle and lower parts, and the shaft body diameters of the upper and lower parts of the shaft body are smaller than the shaft body diameter of the middle part. The upper part of the shaft body is the skeleton fixed shaft 1 that fixes the coil skeleton, and the peripheral surface of the skeleton fixed shaft 1 is provided with a locking device 2 to connect with the coil bobbin. A circle of tap fixing rods 4 is evenly arranged on the surface, and the described one ring of tap fixing rods 4 is preferably composed of six tap fixing rods 4, which are distributed on the tap fixing shaft 3 at an angle of 60 degrees for fixing the taps of the enameled wire; The lower part of the shaft body is the connecting shaft 5, which is used to connect the winding machine.

[0031] The locking device 2 includes holes arranged symmetrically in the radial...

Abstract

The invention relates to a fixing device of a coil framework of a miniature transformer and a method for winding coils. The fixing device of the coil framework consists of five parts, namely a framework fixing shaft, metal springs, steel balls, a tap fixing shaft, a tap fixing pin group and a connection shaft. A transformer framework is fixed and multi-winding taps are led out and fixed, the winding level of the miniature transformer is improved, and a method which is simple, high in efficiency, high in reliability and wide in application is provided for winding of the transformer. By adoption of the fixing device, the method for winding the coils is also improved. By performing the steps of installing a winding fixing device of the miniature transformer, installing the coil framework, winding the coils and fixing winding taps, the method has the advantages that: the winding efficiency of the miniature transformer is improved; the rate of finished products is improved from about 60 percent to above 95 percent, so that wasting is avoided; a transformer manufacturing process is simple and easy to operate; manufacturing efficiency is at least doubled; and the method is wide in application.

Description

technical field [0001] The invention relates to the field of miniature transformer coil winding production, in particular to a fixing device for a miniature transformer coil skeleton and a coil winding method. Background technique [0002] Transformer is a commonly used component in electronic products. Conventional transformers are made by using transformer winding machine or manual winding method. After manufacturing, put the magnetic core into it, and carry out the inductance test. After the specified inductance is met, the magnetic core is bonded and cured. [0003] With the development trend of miniaturization of electronic products, the application of miniature transformers is becoming more and more extensive. The area is small, there are many windings, and it is difficult to fix the coil bobbin and winding taps. [0004] In the production of conventional transformers, the coil bobbin and winding taps are wound by hand and fixed by sticking tape. During the winding p...
