Embodiment 1
[0030] like Figure 1 to Figure 2 As shown, a self-rotating optical fiber coating mask device includes a fixed support structure 1, a drive structure 3 arranged on the fixed support structure 1 and used for optical fiber rotation, and a mask structure 4 for mask protection of the optical fiber during coating. The self-rotating optical fiber coating mask device in this embodiment has a uniform rotation speed during the coating process, and can uniformly sputter the film layer on the side of the optical fiber cylinder. The entire self-rotating optical fiber coating mask device has a separate closed structure, even if the The failure will not affect the environment of the coating chamber, the coating quality, and will not damage the coating device. The device is small in size and sturdy in structure, and is very suitable for a magnetron sputtering instrument with a small coating chamber space. The device is designed with a mask structure 4, which can realize a multi-film structu...
Embodiment 2
[0040] The present invention also provides a method for uniform coating on the side surface of an optical fiber cylinder, using the above self-rotating optical fiber coating mask device, including the following steps:
[0041] S1: Pass the optical fiber with the outer protective layer removed in sequence through the central hole 7 on the fixed shaft 6, the mask block through hole 43, and the central hole 7 on the fixed shaft 6, and fix both ends of the optical fiber to the driven gear through the screw structure 8 On the fixed shaft 6 on 32;
[0042] S2: Adjust the position of the mask block 42 on the support shaft 41, and perform mask protection on the optical fibers that do not require coating;
[0043] S3: Install the self-rotating optical fiber coating mask device in the chamber of the coating instrument;
[0044] S4: Turn on the instrument to evacuate. When the test requirements are met, turn on the stepper motor connected to the power take-off shaft 35 and adjust its sp...
