Description

Technical Field

[0001] The present invention relates to the technical field of power adapter production lines, and in particular to a power adapter complete line. Background Art

[0002] With the development of the times and the continuous progress of science and technology, various electronic and digital products are widely used. They are becoming more and more popular and have become an indispensable part of modern life, such as mobile phones, computers, MP3, MP4, PAD, etc. When digital products are working, they need power supply. Now many electronic and digital products rely on the DC power adapter plug to charge their built-in rechargeable batteries and then rely on the built-in batteries, or directly rely on the DC power adapter plug to connect to the DC power supply to achieve power supply and transmission. Regardless of the above methods, most electronic and digital products often need to work directly with the DC power adapter. Therefore, with the widespread popularity of electronic and digital products, the use and demand of DC power adapters are increasing.

[0003] In the production process of general power adapters, due to the large number of complex processing procedures, many steps are performed manually. With the development of industrial automation, manual operation is time-consuming and labor-intensive, which affects work efficiency and can no longer meet the needs of existing industrial production.
