Embodiment Construction

[0014] Combine below Figure 1 to Figure 4 , the specific steps of the transformer production process provided by the present invention are illustrated by an embodiment:

[0015] (1) Winding and taping process. figure 1 Shown is a commonly used transformer wire frame, the wire frame has a primary winding groove 11, a secondary winding groove 12 and a secondary winding groove 13, and pins 15 are arranged at the ends of the wire frame. combine figure 2 and image 3 As shown, the winding and wrapping process is specifically: the first group of winding 21 → the first group of wrapping tape → the second group of winding 22 → the second group of wrapping tape → the third group of winding 23 → the third group of wrapping tape → After each group of winding wires and each group of wrapping tapes, open the center window and wrap a circle of tapes 28 again (see image 3 , to prevent damage to the enameled wire when assembling the iron core). Since the primary winding is usually thi...

Abstract

The invention relates to a technique for producing a transformer, comprising the following steps: (1) winding wires and wrapping adhesive tapes; (2) assembling an iron core; (3) testing the electrical performance and the safety performance; (4) putting a semi-finished product into a mold of an injection molding machine and carrying out injection molding forming; (5) testing the electrical performance and the safety performance again; and (6) packaging. Compared with the prior art, the invention has the following advantages: the cleanness of the environment is ensured in the injection molding process, and the contamination of a factory is reduced; the invention adopts integrative formation and does not need a prefabricated casing, and the poor hidden dangers of poor binding force and falling-off do not exist; plastics can not be stuck on pins, scraping and washing are not needed, and the appearance is tidy and beautiful; the technique is simple and quick, the work efficiency is greatly enhanced, and the production cost is lowered; and the invention is suitable for large-scale production and can greatly meet the ever growing market demand.

Description

technical field [0001] The invention relates to basic electrical components in the field of electricity, in particular to the production process of transformers used in power audio, instruments and meters. Background technique [0002] The existing small transformers are produced by the potting process, and its main process includes: secondary winding, secondary wrapping, primary to secondary auxiliary, primary winding, primary wrapping, tinning, finishing assistance (in winding After the wire package is finished, open the center window and wrap it with tape to prevent damage to the enameled wire when assembling the iron core), assemble the iron core, withstand voltage test, voltage test, complete feet, install the shell, prepare epoxy resin, potting and vacuumize Repotting (pour epoxy resin into the shell to fill the gap between the wire package and the shell), withstand voltage test, clean the epoxy on the pins, clean the epoxy on the shell, check whether the epoxy is cure...
