Active coupling device for isolator

Abstract

The invention provides an active coupling device for an isolator. The active coupling device comprises a welding rotating base (6), a sliding table mounting plate (5), an adjusting ring positioning base (7), two linear sliding tables, an XMD positioning piece, a positioning base clamping piece (21), two guide supporting columns (8), two oil-free bushings (24), an adjusting ring chuck (11), a quick toggle clamp (16) and the like. The active coupling device for the isolator provided by the invention can be quickly positioned, can be integrally moved to a welding station after active coupling, and the automatic leveling is realized and the height consistency of welding spots is ensured through the adaptation of a bottom spring or an elastic material and a locking structure after leveling, so that a plurality of coupled welding spot rotating arrays can be realized. As the device has the advantages of mounting positions and quick positioning, the working time and material cost of a single product are reduced.

Description

technical field [0001] The invention relates to the field of manufacturing optical communication devices, in particular to an isolator active coupling device. Background technique [0002] In the placement of isolators, there are conventionally two working alignment methods in the prior art: passive coupling (alignment) and active coupling. It is usually called active coupling for products that require power-on to be coupled, and passive coupling for products that can be achieved without power-on. Among them, passive coupling can be positioned only through the aid of a fixture, and the operation is simple, but for the isolator The requirements are high and the cost of a single material is high. The advantage of active coupling is that it has low requirements for the isolator, the cost of a single material is low, and the best coupling position can be achieved. The disadvantage is that it needs to be realized by fine-tuning, and the production efficiency is low. In addition...

Problems solved by technology

[0003] In addition to the above active coupling requirements, BOX products also require laser welding and fixing after mounting. The above conventional active coupling cannot meet the requirements, and it lacks the following functions: 1 , does not interfere with the welding laser beam; 2, can be rotated as a whole (laser welding spots need to be made at a certain distance)

3. It is necessary to ensure that there is no gap between the isolator ring and the BOX (if there is a gap in laser welding, the optical power will change, and if there is a gap after laser welding, the parameters of the product will not meet the requirements, such as pulling force, air tightness properties, optical parameters, etc. do not meet the requirements
