Automatic coating-collecting device after wiredrawing fiber breakage of optical fiber perform and collecting method thereof

Abstract

The invention provides an automatic coating-collecting device used in a way of matching with optical fiber perform wiredrawing equipment. The optical fiber perform wiredrawing equipment comprises a coating mold base and a dancer wheel for extension wiredrawing, wherein a wheel rod is supported on the dancer wheel, the tail end of the wheel rod is in pivot joint with a fixed shaft, and the wheel rod is driven to swing by taking a pivot joint point as a circle center when the dancer wheel reset. The automatic coating-collecting device is characterized by comprising a tray, a pushing mechanism for pushing the tray to be located right below a coating outlet of the coating mold base, a contact sensor and a controller electrically connected with the contact sensor and used for controlling the pushing mechanism to work, wherein the wheel rod can touch the contact sensor during reset swinging. The invention also provides an automatic coating-collecting method after collecting broken fiber by using the collecting device. The problem that after wiredrawing fiber breakage, residual coating in the coating mold base cannot be timely disposed, so that rear equipment is polluted is solved, and after the automatic coating-collecting device is used, the workload can be reduced, materials can be saved, time cost can be lowered, and the production efficiency can be improved.

Description

technical field [0001] The invention belongs to the technical field of optical fiber preform wire drawing, and in particular relates to an automatic collection device and a collection method for coating material after optical fiber preform wire drawing and fiber breakage. Background technique [0002] After fiber breakage occurs during the normal drawing process of optical fiber preform, there is still residual coating in the coating mold base. The existing optical fiber preform drawing equipment does not have the function of automatically collecting coating. Corresponding measures, this part of the paint will drip into the UV lamp, and even drip into the groove of the guide wheel and the surface of the caliper, causing pollution to the parts of the UV lamp, the guide wheel and the lens of the caliper. Production personnel must clean the UV lamp, guide wheel and caliper in time before threading the die again, which increases the workload, prolongs the waiting time for die th...

Problems solved by technology

[0002] After fiber breakage occurs during the normal drawing process of optical fiber preform, there is still residual coating in the coating mold base. The existing optical fiber preform drawing equipment does not have the function of automatically collecting coating. Corresponding measures, this part of the paint will drip into the UV lamp, or even drip into the groove of the guide wheel and the surface of the caliper, causing pollution to the parts of the UV lamp, the guide wheel and the lens of the caliper

The production personnel must clean the UV lamp, guide wheel and diameter measuring instrument in time before threading the die again, which increases the workload, prolongs the waiting time for die threading, and reduces production efficiency

If the production personnel do not clean the UV lamp and the caliper in place, re-drawing may cause quality problems such as poor curing of the optical fiber and many coating defects, resulting in a lot of waste of manpower, material resources and time, seriously affecting the production efficiency of optical fiber drawing
