Optical fiber drawing bad section automatic detection device and method

Abstract

The invention relates to an optical fiber drawing bad section automatic detection device and method. The device comprises a traction assembly, a detection assembly, a storage operation assembly and adisplay assembly; the detection assembly comprises a cladding diameter detector, a coating layer diameter detector and a pocking mark cutting detector; the traction assembly comprises a traction wheel; the traction wheel pulls an optical fiber to pass through the detection assembly and detect the optical fiber, the storage operation assembly comprises a database and a programmable logic controller, the programmable logic controller is connected with the database and the detection assembly, and the programmable logic controller processes a detection result of the detection assembly and uploadsthe detection result to the database. According to the invention, the positions of original unqualified optical fibers are stored to one position, the programmable controller can simultaneously process and calculate various unqualified optical fibers, and removes and automatically uploads the unqualified optical fibers to the database according to set unqualified optical fiber indexes and qualified optical fibers which do not meet the minimum segment length, thereby realizing automatic control.

Description

technical field [0001] The application belongs to the field of optical fiber production and manufacturing, and in particular relates to an automatic detection device and detection method for an optical fiber drawing broken section. Background technique [0002] In the process of optical fiber production, there will be some unqualified optical fibers such as cladding diameter, coating diameter, and pit cutting that do not meet the requirements. In order to ensure the performance of optical fibers, it is necessary to detect and remove these unqualified optical fibers. Accurate detection and removal of unqualified optical fibers is a key step in producing optical fibers and reducing the defective rate. [0003] The existing technology needs to report the kilometers of unqualified optical fibers according to different wire diameter meters, then remove them by manual calculation, and then enter them into the database. The workload is heavy and cumbersome, and the drawn optical f...

Problems solved by technology

[0003] The existing technology needs to report the number of kilometers of unqualified optical fibers according to different wire diameter meters, then remove them by manual calculation, and then enter them into the database. The workload is heavy and cumbersome, and the drawn optical fibers cannot be detected in time.

Omissions and miscalculations are also prone to occur when calculating the length of optical fibers in the existing technology, which makes qualified optical fibers scrapped, increases costs, and causes unqualified optical fibers to flow out and be put into use, reducing the overall service life and performance of optical fibers
