Description

Automatic assembly device and assembly method for passive devices

Technical Field

The application relates to the technical field of passive device assembly equipment, in particular to an automatic passive device assembly device and an assembly method.

Background

The passive devices mainly include WDM devices, isolators, circulators, mixers, and the like, and the WDM devices are described in detail below as examples. The core component of a WDM system is a WDM device whose characteristics determine to a large extent the performance of the overall system. WDM devices are devices for synthesizing and separating optical wavelengths, and the devices for synthesizing and separating are called wave combiners. The most commonly used devices are two types, namely, fiber-fused-taper WDM devices and thin-film filter WDM devices.

The filter type WDM device is composed of twenty layers of dielectric films with different materials, refractive indexes and thicknesses according to design requirements, and the effects of synthesizing and separating different wavelengths are achieved by forming pass bands and stop bands for the different wavelengths. The device has the advantages of compact structure, almost no relation with optical fiber parameters, flat signal passband, low insertion loss, and 0.4dB. The disadvantage is that the design and manufacture are cumbersome, the yield is low, and the price is higher than that of a fuse cone device.

At present, the finished WDM device forming the film filter type can be generally divided into two parts which are butted and combined, namely a reflecting end with a wave-dividing filter function and a collimator with a light collimation function. The reflecting end comprises a filter (Fi l ter), a double-fiber tail fiber, a G-l ens (self-focusing lens) and a small glass tube, and the collimator comprises a C-l ens (collimating lens), a single-fiber tail fiber and a small glass tube. After the two parts of the reflecting end and the collimator are optically coupled, the two parts are packaged and fixed into a whole through glue and a glass tube, and a finished product of the film filter type WDM device is obtained.

The main working unit of the reflecting end is a filter (Fi later), and the transmission of the spectrum with the specified wavelength is obtained mainly by utilizing the interference principle of light, and the spectrums with the other wavelengths are reflected and absorbed. The filter is deposited on the optical substrate through the vacuum coating machine to achieve different optical effects. When the mixed light of multiple wavelengths passes through the filter, interference effect is generated due to different refractive indexes, so that the light of specific wavelength has very high transmittance and the light of other wavelengths is reflected and absorbed. The filter (Fi l ter) is assembled with the G-Lens and the double-fiber tail fiber to form a reflecting end, so that the reflecting end becomes an important unit capable of finishing the transmission of light with specified wavelength and the reflection and absorption of light with other wavelengths.

However, the light with the specified wavelength transmitted from the reflecting end needs to be guided into the optical fiber by a carrier for transmission, the light with the specified wavelength transmitted from the reflecting end can be gradually dispersed in the air, a unit with a light focusing and collimating function is needed to be coupled and butted with the reflecting end, and the light with the specified wavelength is collimated and then is converged into the optical fiber, so that the transmission of the light with the specified wavelength is completed, and the unit is a collimator.

The main working unit of the collimator is C-Lens, which is a single refractive index Lens with a certain curvature radius, and when divergent light passes through the curved surface of the C-Lens, the convergence and collimation of light rays are completed due to the refraction effect of the light. The C-Lens and the single fiber pigtail are assembled to form the collimator, so that the converged and collimated designated optical waveguide can be introduced into the optical fiber to complete the transmission of the designated optical wavelength.

The operation steps of butt coupling and dispensing packaging are performed between the produced reflecting end and the collimator, and are hereinafter referred to as an assembly step.

Taking the WDM assembling process as an example, in the existing apparatus for manufacturing the WDM assembling process, except that the butt coupling portion of the reflecting end and the collimator is completed by using an electric sliding table, the rest operations are completed manually, such as dispensing, packaging, curing, etc.

In the existing post operation, after the collimator and the reflecting end are manually put on the shelf, staff needs to manually follow up and confirm the butt coupling parameters of the product in real time and adjust the materials. After the personnel judges and confirms that the butt coupling parameters are qualified, glue needs to be manually smeared on the pipe walls of the reflecting end and the collimator, then the glass pipe is manually penetrated to sleeve the reflecting end and the collimator into the reflecting end and the collimator, and then the glass pipe is rotated and the adjusting frame is repeatedly pushed to conduct glue sucking operation, so that the glue appearance is uniform. After the glue sucking is finished, staff is required to judge the appearance condition of the glue sucking in the glass tube on line, then the butt coupling of the primary reflecting end and the collimator is carried out to enable the final parameters to be qualified, and finally the ultraviolet light source is manually pushed to irradiate the glue to enable the glue to be solidified, so that the WDM product is finished.

The operation related to the above process is basically completed manually, so that the operation of manual participation on line is too much, great effort is required to be consumed, the production efficiency of the product is low, and meanwhile, the consistency problem caused by human factors also exists.
