AI Technical Summary

Problems solved by technology

In CWDM coupling equipment, the coupling method used is the common manual coupling method, which is inefficient and needs to be tested separately after coupling
The clamping and positioning fixtures of FA and CHIP are mostly designed for a single product, and the clamping method is relatively primitive, and the clamping force cannot be controlled
[0004] In addition, during the coupling process, since the tail connector is directly inserted into the jumper, there is no fixing device, and the test and coupling values ​​have a certain probability of deviating from the normal value

Abstract

The invention provides a CWDM coupling device, which includes an FA clamping mechanism, a CCD displacement mechanism, a CHIP clamping mechanism and a PD displacement mechanism. The FA clamping mechanism includes an FA clamping component and an FA sliding component. The FA sliding component can move the FA with a pigtail to one end of the CHIP to couple the FA with a pigtail to the CHIP; the PD displacement mechanism includes a PD displacement component and a PD, The PD displacement component can move the PD to the upper side of the other end of the CHIP, so that the PD receives the light transmitted by the CHIP, and detects the power of the light; the CCD displacement mechanism includes a gantry, a single-axis robot, a manual adjustment component, a slider, CCD, UV lamp assembly and red light assembly. The automatic coupling is automatically controlled by the control system, which improves the coupling efficiency and coupling accuracy. And the coupling process is provided by the force sensor and the light received by the PD to provide feedback, and the light beam emitted by the red light confirms that the position meets the requirements.

Description

technical field [0001] The invention relates to the technical field of CWDM coupling equipment, in particular to a CWDM coupling device. Background technique [0002] CWDM is a sparse wavelength division multiplexer, also known as a coarse wavelength division multiplexer. CWDM uses an optical multiplexer to multiplex optical signals of different wavelengths into a single optical fiber for transmission. the receiving device. [0003] At present, the CWDM coupling process is mainly to manually adjust the coupling between FA and CHIP, and to assist the coupling process according to the observation results of the overlooking CCD; after the coupling is completed, manually dispense glue, then hold or push the UV lamp to realize the UV function, and then release the clamp after completion , unloading, and then adjust the knob to the initial position. In CWDM coupling equipment, the coupling method used is the commonly used manual coupling method, which is inefficient and needs t...
