An air flotation device for optical device coupling and using method

Abstract

The invention discloses an air flotation device for optical device coupling, which comprises a support table, a ball seat, a floating ball, a compressed air joint and a vacuum joint. The support table is a cylindrical support table, and the inside of the support table has an installation cavity. The ball seat is a cylindrical structure, and the inner side wall of the ball seat is provided with an annular groove, and the side wall of the ball seat is symmetrically provided with a first air path and a second air path, both of which are Connected with the annular groove, the floating ball is movably embedded inside the upper end of the ball seat, and the top of the floating ball extends to the outside of the upper end of the ball seat, the top of the floating ball is provided with a horizontal plane, and the top of the floating ball is provided with a working position slot . The invention can conveniently make the bottom of the optical fiber socket and the two surfaces of the upper part of the semi-finished product of the optical device completely flat, avoid the existence of angles, the relative position of the optical port and the optical device will not change after welding, and effectively ensure the performance of the optical device.

Description

technical field [0001] The invention belongs to the technical field of optical device production, and in particular relates to an air flotation device for coupling optical devices and a method of using the same. Background technique [0002] Optical devices are divided into active devices and passive devices. Optical active devices are optoelectronic devices that require additional energy to work in optical communication systems and can convert electrical signals into optical signals or convert optical signals into electrical signals. The heart of the transmission system. Optical passive devices are optoelectronic devices that do not require external energy to drive work. [0003] The optical port of the optical device is connected. After the coupling is completed, the optical port and the welding surface of the device need to be flattened before laser welding to ensure that the relative position of the two coupling components does not change during the welding process. The...

Problems solved by technology

[0005] For the coupling welding equipment existing in the prior art, the mechanical method is generally used for flattening. It is difficult for the mechanical flattening method to completely flatten the two surfaces, and there will always be a little angle, which will cause the relative position of the optical port and the optical device to change after welding. For the problem of affecting the performance of the optical device, the present invention provides a method that can easily flatten the bottom of the optical fiber socket and the upper part of the semi-finished optical device, avoiding the existence of angles, and the relative position of the optical port and the optical device will not change after welding , an air flotation device for optical device coupling that effectively guarantees the performance of the optical device and its use method
