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 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. It consists of an automatic rod pushing device, an automatic filling and discharging device for matching oil, and a preform tester; the automatic rod pushing device includes a test bench, a support frame, a servo motor and a push arm, and a guide rail is installed on the test bench, and the support frame and tester are fixed on the guide rail , the support frame slides along the guide rail, the upper part of the test bench is equipped with a push arm track through the bracket, the servo motor is installed in the push arm track, the servo motor is connected to the push arm, the push arm is hinged with the push rod, and the push rod is equipped with a push rod head. The rod head pushes forward against one end of the preform rod; the support frame has a roller, which is installed on the central axis, and the central axis is fixed on the longitudinal axis of the support frame. The automatic filling and matching oil device includes a test chamber, a lifting screw, a scale, a motor and a matching The oil bottle and the test chamber are set 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...
