Problems solved by technology

[0006] It can be seen that the main problems of the traditional mechanical grinding and polishing method are: ①The damage of the fiber end face and the thickness of the degenerated layer cause the reflected wave intensity at the connection interface; Directly affect the insertion loss and return loss transmission performance of the optical fiber connector; ③Low grinding efficiency, large consumption of diamond abrasive paper, high grinding cost

Abstract

The present invention relates to an ultrasonic mechanical composite grinding / polishing method for optical fibre connector end face and its equipment. It is characterized by that the oscillating ultrasonic signal with 20-30 kHz which is produced by ultrasonic source can be transmitted from energy transducer, and passed through amplitude-changing bar and clamp and transferred onto interface between the optical fiber connector end face and grinding / polishing medium on the grinding / polishing disk: the self-rotation motor and revolution motor controlled by control system can by used for driving grinding / polishing disk, so that the ultrasonic / mechanical composite grinding / polishing process for processing optical fibre connector end face can be implemented.

Description

Technical field: [0001] The invention relates to the field of grinding and polishing machinery, in particular to an ultrasonic mechanical composite grinding and polishing method and device for the end face of an optical fiber connector. Background technique: [0002] After the optical fiber connector is assembled with the optical fiber, the insertion loss should be as low as possible, and the return loss should be as high as possible. Therefore, the end face of the connector needs to be ground and polished to ensure accurate and effective physical contact between the end face of the optical fiber connector and the end face of the optical fiber in the optical connector when the connector is inserted into the optical connector. [0003] The current processing technology for the end face of the optical fiber connector is to use the traditional mechanical grinding and polishing process, that is, use a special fixture to press the end face of the fiber optic connector ferrule on ...
