AUTOMATICALLY MANUFACTURING APPARATUS OF PLATE COIL ELEMENT FOR TRANSFORMER

The present invention relates to an apparatus for manufacturing a transformer for a communication terminal, and more particularly, to an automatic manufacturing apparatus for a flat coil element for a transformer suitable for automatically manufacturing a flat coil element for a transformer in one production line .

In general, a transformer has a primary side and a secondary side, and in general, the primary side is used as an input stage and the secondary side is used as an output stage.

Among transformers, a coil component wound with a triple insulated wire is used (especially, used as a secondary side) for a small transformer used in a mobile phone charger.

However, the coil parts wound with the triple insulated wire have a problem in mass production, such as the need to directly peel the coating of the wire, and the triple insulated wire is not wound uniformly, so there is a problem with a high defect rate. In addition, if a coil component wound with triple insulated wire is used as the secondary side of the small transformer, the primary side and the secondary side must be spaced apart by a predetermined distance to ensure sufficient dielectric withstand voltage of the small transformer. As the size increases, there is a problem in that the leakage inductance of the small transformer increases accordingly.

In addition, in the current situation that requires improvement of the output of small transformers for high-speed charging of mobile phones, etc., when using a coil component wound with triple insulated wire on a small transformer as the secondary side, sufficient In order to secure the dielectric breakdown voltage, since the primary side and the secondary side of the small transformer must be further spaced apart than in the prior art, the size of the small transformer becomes larger, and accordingly, the leakage inductance also increases. In addition, as the primary side and the secondary side are further spaced apart, the efficiency of the small transformer also decreases.

Accordingly, recently, attempts have been made to utilize a plate coil in a transformer.

A method of manufacturing such a flat coil will be briefly described.

After inserting the flat coil into the primary injection mold, insert injection is performed, the first punching operation is performed to remove unnecessary parts for the flat coil that has been subjected to the insert injection operation, and the second injection is performed after the first punching operation is performed. The secondary injection operation was performed by inserting it into the mold, and the secondary punching operation was performed to separate the product by cutting the terminal for the flat coil that had completed the secondary injection operation.

However, in the conventional flat coil manufacturing method, after each injection operation or punching operation is performed, the operator has to insert the semi-finished product one by one in the next step.
