The polishing is carried out after the optical fiber is positioned by the clamp and the straightness is controlled, the spray blowing device is used for blowing off fragments during the polishing, and the polishing stability is improved; and in addition, the combination of two kinds of abrasive paper is utilized for polishing, the finish degree is improved, visually visible optical fiber end paraboloids and saw tooth surfaces after the original polishing are eliminated, and the frequently generated optical fiber communication fault problems of a control system are solved.

Description

technical field [0001] The invention relates to the field of communication optical fiber repairing and polishing, in particular to a high-frequency communication optical fiber repairing method and a repairing device. Background technique [0002] Many welding machines used in cold rolling use laser welding machines. The high-frequency communication optical fiber is used as the communication medium between the terminal control system of the welding machine and the high-frequency drive control system. This optical fiber is a special communication for high-frequency communication. Before the optical fiber is used, its optical fiber head must be polished.

Problems solved by technology

In the prior art, grinding is to pinch the head of the optical fiber by hand, and then keep the vertical posture to repeatedly grind the head of the fiber on the sandpaper. When it is relatively flat visually, insert the smoothed head of the fiber into the fiber to fix it. The plug can be connected to the optical communication receiving end. Due to the rough grinding method, the straightness and smoothness of the grinding cannot be guaranteed, resulting in unstable optical fiber communication. In addition, when the laser control communication is abnormal, the optical fiber head is often repeatedly ground. , Repeated installation and repeated failures, the fault processing time is long, the general grinding time is more than 3 hours, and the faults often occur repeatedly, which seriously affects the production of the unit; other similar control systems using this high-frequency communication optical fiber also often occur. question
