Problems solved by technology

[0003] In the prior art, the patent 201420327137.3 proposes a method for online detection of concentricity. According to this method, after a deviation occurs, it is necessary to observe the deviation with the naked eye and adjust it manually, and the accuracy is insufficient.
Patent application 201510736454.X proposes a method to improve fiber screening strength and coating concentricity. This method needs to be carried out when the production line is shut down, and online detection cannot be performed
Patent application 201610429651.1 proposes a device and method for improving the concentricity of optical fiber drawing and coating online. This method also has the problems of visual observation, manual adjustment, and low precision.
It can be seen that there are three problems in the adjustment and monitoring methods in the prior art: 1. Since the length of the laser projection is observed with human eyes, there will inevitably be certain deviations; 2. It is impossible to monitor the concentricity of the optical fiber online in real time; 3. In the process of mechanically adjusting the coating cup, the precision is insufficient, the adjustment effect cannot be guaranteed, and manpower is wasted

The optical fiber coating concentricity canbe online monitored automatically and conveniently, and the two devices solve the problems of inconvenience and low precision of online monitoring and adjusting in the prior art, can conveniently andeffectively monitor and adjust the optical fiber coating concentricity, has good practicability and can be widely applied to the technical field of optical fiber coating and the like.

Description

technical field [0001] The invention relates to the field of optical fiber technology, in particular to an online adjustment device for optical fiber coating concentricity, an online monitoring and adjustment device. Background technique [0002] The optical fiber coating process is conducive to enhancing the strength of the optical fiber and is a necessary step in the optical fiber production process. During the coating process, due to the poor alignment of the production line, it is easy to cause a large deviation in the concentricity of the optical fiber cladding coating, which affects the performance of the optical fiber. At present, the measures to control the concentricity error of the coating layer during the wire drawing process are mainly: to ensure the concentricity of the coating during the wire drawing process by mechanically calibrating the center of the wire drawing tower and the center of the horizontal mold base. [0003] In the prior art, patent 20142032713...
