For product packaging, the optical fiber coupling process has always been a very important operation process. Therefore, it is very necessary to develop an optical fiber coupling platform with low cost, high operation efficiency, and stable product qualification rate. Summary of the Utility Model

The laser receiver loading jig is connected to the coupling platform. In front of the laser receiver loading jig is a welding heating clamp for heating solder wire. In front of the welding heating clamp is an optical fiber loading jig installed on the three-axis coupling stage. The optical fiber loading jig is used to fix the optical fiber, and the three-axis coupling stage is used to couple the optical fiber to the position where the response current of the laser receiver is the largest.

The heating clamp locking rod is used to connect and lock the heating clamp to the laser receiver loading jig base. The positive and negative electrodes of the power supply are connected to both sides of the heating clamp, and the welding position is heated and welded through the Joule heat effect.

An optical fiber locking buckle is connected above the optical fiber limiting groove to fix the optical fiber in the groove. The optical fiber is connected to a return loss tester that provides a light source for the coupling of the laser receiver.

[0010] The three-axis coupling platform includes an X-axis screw rod, a Y-axis screw rod, and a Z-axis screw rod for realizing movement in three directions. By rotating the screw rods, the position of the optical fiber relative to the laser receiver is moved to achieve coupling.
