Problems solved by technology

According to this method, a lot of manual labor is required in the test, especially when more points need to be tested, it will increase the labor intensity and increase the manufacturing cost of the optical fiber preform
In addition, when the number of test points increases, the test instability due to human factors will also increase

Embodiment Construction

[0026] Refer to attached Figure 1~2 , an optical fiber preform automatic testing system is composed of an automatic rod pushing device, an automatic filling and discharging device for matching oil and a preform tester. The automatic rod pushing device, the matching oil automatic filling and discharging device and the preform tester are connected to the computer PC control system through the programmable controller PLC. The PC control system controls the operation of each device according to the set program to realize the automatic test of the optical fiber preform. The preform tester can be a commercially available P104 optical fiber preform tester.

[0027] The automatic rod pushing device includes a test bench 1, a support frame 4, a servo motor 21 and a pushing arm 9. A guide rail 2 is installed on the test bench 1, a support frame 4 and a tester 3 are installed on the guide rail 2, and the support frame 4 can slide along the guide rail 2. The top of the test bench 1 is ...

Abstract

The invention relates to the technical improvement of optical fiber preforms production, in particluar to a system and a method for automatically measuring an optical fiber preform. The system consists of an automatic rod-pushing device, an automatic matched oil charging and discharging device and an preform tester, wherein the automatic rod-pushing device comprises a testboard, a carriage, a servo motor and a pushing arm, a guide rail is arranged on the testboard, the carriage and the tester are fixed on the guide rail, the carriage can slide along the guide rail, the upper part of the testboard is provided with a pushing arm track through a support, the servo motor is arranged in the pushing arm track and is connected with the pushing arm which is hinged with a push rod, the push rod is provided with a push rod head which moves forward and props against one end of the preform, the carriage is provided with a rolling shaft arranged on a central shaft, and the central shaft is fixed at the vertical axis of the carriage; and the automatic matched oil charging and discharging device comprises a measuring cavity, a lifting screw, a scaleplate, a motor and a matched oil bottle, and the measuring cavity is arranged in the preform tester.

Description

technical field [0001] The invention relates to an optical fiber preform automatic measurement system and its measurement method, which relate to the technological transformation of optical fiber preform production. More precisely, the invention relates to an automatic measurement optical fiber preform system and its test method. Background technique [0002] In the current production of optical fiber preforms, it is necessary to measure the preform core rod to obtain accurate refractive index profile distribution for process feedback and outer cladding design. Measuring such a preform core rod is a part of preform measurement, and currently it is mainly measured manually. [0003] The operator inserts the core rod of the optical fiber preform to be tested into the test cavity, and determines the position of the point to be tested. Squeeze the matching oil bottle to press the matching oil into the test chamber, keeping the matching oil full of the test chamber. Turn on the...
