Description

Technical Field

[0001] The utility model relates to the technical field of optical fiber welding, in particular to an optical fiber interface alignment device. Background Art

[0002] Fiber optic is short for optical fiber, which is a fiber made of glass or plastic that can be used as a light transmission tool. The fine fiber is encapsulated in a plastic sheath so that it can be bent without breaking. Usually, the transmitting device at one end of the fiber uses a light-emitting diode or a laser to transmit light pulses to the fiber, and the receiving device at the other end of the fiber uses a photosensitive element to detect the pulses.

[0003] According to a fiber optic interface alignment device disclosed in Chinese patent publication number CN 215067412 U, it is proposed that the existing fusion splicer needs to be manually installed on the hot melt machine for alignment during the fusion splicing process, and the fiber heat shrink tube needs to be manually installed at the fiber fusion splicing position after being sleeved, which is easy to cause the welded fiber to break and increase the work procedure. The patent peels the two ends of the optical fiber and installs it in the fiber optic groove on the push plate, drives the two ends of the optical fiber to align through the driving device, uses the tightening alignment device to align the two ends of the optical fiber, welds through the discharge electrode, and then pushes the heat shrink tube to be sleeved on the fiber welding position through the sleeve cover, which can achieve rapid alignment of the fiber fusion end, and can efficiently sleeve the heat shrink tube for heat melting, effectively avoiding the breakage caused by manual operation, reducing the operator's work procedures, and increasing work efficiency. However, in actual operation, the device still needs to manually adjust the optical fiber beyond the tightening alignment device by a certain distance to splice the two sections of the cable, which increases the difficulty of use and low work efficiency.

[0004] To this end, we propose a fiber optic interface alignment device to solve the problem that the above device requires manual installation and reduces work efficiency. Utility Model Content
