Abstract

The invention discloses an online weighing system being suitable for an OVD process, which includes an upper gripper mechanism, a lower support mechanism, and a weighing unit. The upper gripper mechanism includes a pedestal, a linear slide rail, and an upper rod-holding gripper which is connected to upper end of a powder rod and is connected to the lower end of a rotary shaft; the upper end of the rotary shaft is connected to the weighing unit through a horizontal bearing and a horizontal bearing base; a rotary outer sleeve tube is arranged outside the rotary shaft and is connected to the pedestal through the linear slide rail; the pedestal is connected to a chamber wall of a deposition chamber; the lower support mechanism includes a lower gripper pedestal which is connected to a bottom board of the deposition chamber, and a lower gripper elastic member arranged around the lower end of the powder rod; and the lower gripper elastic member is connected to the lower gripper pedestal through a connection mechanism. The system is free of interference between weighing function and self-rotational movement, so that high rotation precision of the powder rod is maintained and the weight of the rotating powder rod can be accurately measured in real time.

Description

technical field [0001] The invention relates to an online weighing system suitable for OVD technology, which belongs to the technical field of optical fiber preform rod manufacturing equipment. Background technique [0002] In the field of optical fiber preform manufacturing, the OVD (Outside Vapor Deposition) process is usually used to manufacture the outer cladding of optical fiber preforms. Due to its high deposition efficiency and low requirements for raw materials such as water peak and purity, it has been more and more widely used. . The deposition equipment of the OVD process can be roughly divided into two structural forms, the axis horizontal arrangement and the axis vertical arrangement. For the latter, due to the vertical arrangement of the axis, during the deposition process, as the diameter of the powder rod becomes larger and larger, the influence of gravity on the axis of the preform is not as great as that of the equipment arranged horizontally, so there is ...
