Description

Technical Field

[0001] The invention relates to the field of ear needle jewelry processing, and in particular to a laser welding device for an empty ring buckle chain. Background Art

[0002] As people's demand for material life continues to increase, there are more and more types of jewelry, such as crowns, earrings, jewelry and necklaces. As these accessories develop, they need to meet more and more needs of people. For earrings, in addition to color and style, earrings are also becoming more and more lightweight, so hollow ear needle tubes are produced. However, compared with traditional solid ear needle tubes, hollow ear needle tubes are thinner and not suitable for excessive shape modification, such as setting threads or buckles on the ear needle tubes, which will greatly increase the production cost. In order to control the production cost of hollow ear needle tubes, manufacturers generally produce straight ear needle tubes and will not make too many deformation modifications. This increases the difficulty of fixing the metal jewelry and the ear needles, especially in the modern production environment that increasingly requires automated production. At present, there is still a lack of a device that can automatically assemble hollow tube ear needles on the market. Summary of the Invention
