Manufacturing method of flyback transformer

Abstract

The invention discloses a manufacturing method of a flyback transformer. The manufacturing method comprises steps as follows: (1), the winding number of coils is set; (2), a to-be-wound primary magnetic bar is fixed on a jig; (3), a wire head with required length by a product is reserved; (4), the wire head winds tightly along the edge of the jig for one circle counterclockwise, and a wire tail presses the wire head which winds for one circle in a 1 / 2 position of a reverse side of the magnetic bar, is parallelly attached to the first circle of copper wire which finishes winding, and is fixed; (5), the wire head is perpendicularly guided out to the tail end of the magnetic bar along the surface of the magnetic bar and is fixed, and equipment is started for winding; (6), the wire tail is tightly attached to the tail end of a winding, a knot is tied in a cross manner, and the wire tail is cut off according to the required length after winding to form a semi-finished product for standby application; (7), during later process production, the knot tied on the primary magnetic bar is untied in the direction opposite to the tying direction, and the wire head or the wire tail is connected to the corresponding position according to requirements of a product; and (8), potting is performed. With the adoption of the manufacturing technology, the voltage withstanding property and the anti-ageing property of the product are improved, the production efficiency is high, and the service life of the product is prolonged remarkably.

Description

technical field [0001] The invention relates to a method for manufacturing a high-voltage bag, in particular to a high-voltage bag applied to a gas pulse igniter, an ozone generator, and an anion generator. Background technique [0002] The high-voltage pack is the energy supply device for the pulse igniter, ozone generator, and negative ion generator. Its first function is to provide high-voltage output for the pulse igniter, and its second function is to provide energy for the ozone generator and negative ion generator. The magnetic core provides energy for the high voltage pack. [0003] In the current production process of the high-voltage package primary magnetic core, after the enameled wire is wound on the magnetic rod, a layer of tape needs to be pasted on the wound enameled wire, and the primary winding is fixed with the tape. During the assembly process of the high-voltage package, the primary magnetic core and the secondary magnetic core need to be combined, and ...

AI Technical Summary

Problems solved by technology

[0005] 1. When the high-voltage package is filled with primary glue, since the tape is wound on the primary magnetic core, it is difficult for the epoxy resin to penetrate into the tape, which leads to the breakdown of the winding copper wire during the use of the product;

[0006] 2. When the primary magnetic core of the high-voltage package is wrapped with tape, the tape is easy to adhere to impurities, which may easily cause flash fire inside the product and cause the product to be scrapped;

[0007] 3. The primary wrapping tape of the high-pressure package, the product is exposed to high temperature of 80°C to 120°C and low temperature of -5°C to -20°C, the tape will age, which will easily lead to cracking of the potting resin of the product;

[0008] 4. The production efficiency of the primary rubber wrapping of the high-pressure package is low, resulting in a high unit price for a single labor;

[0009] 5. For the primary packaging tape, the glue on the tape is easy to dry, causing the tape to loosen and resulting in the scrapping of the product;

[0010] 6. The primary tape is not wrapped properly, and the tape exceeds both ends of the magnetic rod, resulting in poor appearance of the product;

[0011] 7. The knife used to cut the tape during the production of the primary tape is easy to cut the fingers;

[0012] 8. Packing tape wastes material
