COC optical fiber automatic coupling and packaging device and method

Abstract

The invention provides a COC optical fiber automatic coupling and packaging device and method. A base clamping mechanism is used for clamping a COC base, and the COC base is provided with a tail fibermounting groove, a laser chip and a lens. A tail fiber clamping mechanism is used for clamping the tail fiber and making the tail fiber coupled to the COC base, the tail fiber is composed of an optical fiber and a tail fiber fixing block, one end of the optical fiber penetrates through the tail fiber fixing block, and the other end of the optical fiber is connected with an optical power meter. Apower-up mechanism is used for supplying power to the laser chip, a monitoring mechanism is used for monitoring the relative position of the tail fiber and the COC base, and a laser welding mechanismis used for welding the tail fiber to the COC base. The method includes the steps of device clamping, optical fiber coupling, welding and fixing, and packaging. The device is reasonable in design, high in detection precision and high in equipment activation rate, the manual participation degree is reduced, the product damage phenomenon is avoided, and the production cost is effectively reduced.
