Abstract

The invention provides a device for automatically adjusting the straightness of a mandril of an optical fiber preform as well as and an adjustment method. The device comprises a fixed base, a controlcabinet, a heating device, a pressing device, and two support rotating wheels arranged above the fixed base, wherein the adjacent sides of the two support rotating wheels are used for supporting and placing the mandril, and the two support rotating wheels are driven to rotate along the same direction by means of a drive motor; the control cabinet is internally provided with a microcontroller, andthe microcontroller controls the drive motor to rotate by means of a drive circuit; the heating device is used for softening the mandril; the pressing device is used for applying downward pressure tothe mandril. The device for automatically adjusting the straightness of the mandril of the optical fiber preform as well as and the adjustment method are high in intelligence degree and have the advantages of being automatic in detection, high in adjustment accuracy, high in efficiency, and the like; the whole device does not need to be manually operated; a pressure sensor and a laser diameter measuring device are used for automatically detecting the straightness; the pressing device is used for carrying out pressing adjustment on abnormal points until the accuracy meets the standard position.

Description

technical field [0001] The invention belongs to the technical field of optical fiber equipment manufacturing, and in particular relates to an automatic adjustment device for straightness of an optical fiber prefabricated core rod. Background technique [0002] Straightness is the difference between the maximum value and the minimum value of the radial direction measured by the indicator when the bar rotates around the reference axis without axial movement. difference. [0003] In the field of optical fiber preforms, the straightness of glass core rods will seriously affect the production quality of optical fiber preforms and optical fibers, so it is necessary to accurately adjust the core rods with large straightness. At present, the domestic optical fiber preform manufacturing industry is developing relatively slowly. , the corresponding mandrel straightness adjustment equipment is also very little, mainly using the hydrogen-oxygen flame torch to heat it at high temperatur...
