[0002] With the continuous improvement of the economic level and the continuous progress of technology, communication technology and its services have developed rapidly, and data centers have also risen rapidly. The demand for optical devices such as planar waveguide silicon optical chips has increased sharply. Planar waveguide optical coupling is to fix the chip and the optical fiber on the tooling fixture, start the CCD imaging device, observe whether the chips are parallel, and then manually rotate the manual three-dimensional adjustment device to adjust the parallelism between the chip and the optical fiber in the three directions of θX, θY, and θZ; then, the optical fiber is optically coupled with the chip by controlling the movement of the electric three-dimensional adjustment device in the three directions of X, Y, and Z; finally, the optical device is fixed using UV optical glue.

[0003] At present, planar waveguide optical coupling uses a fixture to position the product, and the planar waveguide optical coupling is positioned by three-dimensional movement adjustment of the fixture. Although planar waveguide optical coupling can be achieved, the three-dimensional debugging operation of the planar waveguide optical coupling product is inconvenient, and the single-station design requires the planar waveguide optical coupling of the product to be gradually operated on a single station, such as loading, three-dimensional positioning coupling, and unloading, which not only has low efficiency but also poor safety.
