Wire drawing online defect marking device

Abstract

The invention provides a wire drawing online defect marking device. The device is characterized by comprising a PLC control system, an ink jet system, a drying system and a bottom plate; the PLC control system is electrically connected with the ink jet system; the drying system is electrically connected with the PLC control system; the PLC control system is used for conducting linkage control and marking the path distance of a defective optical fiber; the ink jet system is used for controlling spraying of pigment and marking the defective optical fiber; the drying system is used for drying the marked optical fiber; the ink-jet pigment is uniformly smeared on the surface of the optical fiber; two symmetrical fixing plates are fixedly installed on the upper surface of the bottom plate; the PLC control system is convenient to perform linkage control and mark the path distance of the defective optical fiber; the ink jet system is convenient to perform control over pigment spraying and mark the defective optical fiber; the drying system is used for drying the marked optical fiber; and an optical fiber detector is convenient to detect defects of the optical fiber.

Description

technical field [0001] The invention relates to the technical field of wire drawing production, in particular to an online defect marking device for wire drawing. Background technique [0002] In the preform drawing production process, there will inevitably be optical fiber defects, such as excessive fluctuations in the diameter of the bare optical fiber, coating bubbling, and small bubbles in the coating, etc. These bad optical fibers must be cut and discarded in the subsequent screening process. [0003] For example, the Chinese patent whose authorized announcement number is CN111413350A discloses a method and device for detecting defects in optical fiber cables. The method is an image comparison method, including step 1: establishing a database, establishing a classification of cable quality, and marking the type of damage; Step 2: Take pictures in real-time production, number them according to the barcode of the small coil, compare the captured pictures with the standar...
