Automatic adhesive dispensing device and method for coupling of planar waveguide type components

Abstract

The invention provides an automatic adhesive dispensing device and method for coupling of planar waveguide type components. The automatic adhesive dispensing device comprises a single-shaft movement controlling module, an air cylinder movement module and an adhesive dispensing module, wherein the single-shaft movement controlling module is used for driving the adhesive dispensing module to a predetermined adhesive dispensing position; the air cylinder movement module is used for driving the adhesive dispensing module to move up and down, so that adhesive dispensing syringe needles are alignedto the predetermined adhesive dispensing positions, and an air cylinder in the air cylinder movement module is connected with a movement end of the single-shaft movement controlling module; and the adhesive dispensing module comprises an adhesive dispensing syringe cylinder up-down position fine adjustment slipway, adhesive dispensing syringe cylinder front-rear position fine adjustment slipways,adhesive dispensing syringe cylinder left-right position fine adjustment slipways, adhesive dispensing syringe cylinders and adhesive dispensing syringe needles. According to the automatic adhesive dispensing device and method disclosed by the invention, the adhesive quantity and the adhesive dispensing quality are controlled through equipment, the automatic adhesive dispensing device has the advantages of being high in product consistency, reliable, capable of saving labor cost and the like, besides, automatic adhesive dispensing of various planar waveguide type components can be compatible.

Description

technical field [0001] The invention relates to an automatic glue dispensing technology, in particular to an automatic glue dispensing device and method for coupling planar waveguide devices in optical communications, belonging to the field of manufacturing equipment. Background technique [0002] Planar waveguide devices are widely used in the field of optical communication, mainly including arrayed waveguide grating (ArrayedWaveguide Grating, AWG), PLC type variable optical attenuation (VOA), MZI type attenuator, Y waveguide, etc. Chinese patent CN102540350A, "A temperature-insensitive arrayed waveguide grating that realizes bilinear temperature compensation", Chinese patent CN107608029A, "An array adjustable optical attenuator and its attenuation and manufacturing method" and other introductions to such devices Applications and advantages. [0003] These devices are all planar optical waveguide devices, and the chip forms of the devices are similar, so the same automatic...

AI Technical Summary

Problems solved by technology

[0005] For the manual dispensing process, it is greatly affected by human factors, such as the shape of the glue curing, the dosage is uncontrollable, bubbles introduced by multiple dispensing affect the propagation of light in the optical path, resulting in poor product consistency and unqualified device test parameters, etc.
