Abstract

The invention discloses an online loose body density measurement method and device and relates to the field of VAD (vapor axial deposition) of optical fiber preform rods. The device comprises a weight measurement module, a volume measurement module and a density calculation module, wherein the weight measurement module is fixedly arranged onto the lifting platform of VAD equipment for measuring the weight of a preform rod loose body; the volume measurement module is fixedly arranged outside a deposition cavity for scanning and calculating the volume of a preform rod loose body. The online loose body density measurement device implements measurement in a state that deposition of the preform rod loose body is completed. Therefore, the online loose body density measurement device can ensure safety of production of the preform rod loose body, timely and accurately feed density data of the preform rod loose body back, avoid rejection of a furnace tube due to the fact that low-density optical fiber preform rod loose bodies fall into the furnace tube, save offline testing operation, significantly reduce the workload and the working time of operators and effectively improve the production efficiency.

Description

technical field

[0001] The invention relates to the field of VAD manufacturing of optical fiber prefabricated rods, in particular to a method and device for on-line measuring the density of a loose body. Background technique

[0002] In recent years, the telecommunications industry has accelerated the construction of mobile base stations according to the "Twelfth Five-Year Plan", and due to factors such as anti-dumping of optical fiber preforms, the demand for the industry has grown rapidly, and there has been a huge shortage of optical fiber preforms in China, and this phenomenon Affected by the rapid growth of domestic telecommunications fixed asset investment, and the demand for optical fibers by domestic telecom operators will continue to grow rapidly in the next few years, it is extremely important for the current optical fiber preform production enterprises to stabilize and increase the production capacity of optical fiber preforms. meaning.
