Description
Technical field
The present invention relates to the grinding method of optical fiber ceramic lock pin, particularly based on the grinding technics of built-in type quick connector ceramic insertion core.
Background technology
Ceramic insertion core (English name: ferrule) is the one of fiber stub, it is the ceramic cylinder tubule fired with zirconium dioxide, quality is hard, the pure white exquisiteness of color and luster, its finished product accuracy reaches submicron order, the most frequently used in Networks of Fiber Communications, that quantity is maximum precision positioning parts, usually for the manufacture of the joints of optical fibre, the optically-coupled etc. of device.The main effect of ceramic insertion core be realize optical fiber physics docking (also referred to as optical fiber cold connection), usually with porcelain bushing (English name: sleeve) with the use of.In communication industry standard YD/T 1198-2002 " requirement of fiber-optical movable connector pin body technique ", fiber stub body is defined as follows: the cylinder of precise centering in fiber active linker plug, there is a micropore at center, as fixed fiber.Its Main Function and requirement are: the docking 1, ensureing two optical fiber, and single mode requires that axial deviation is less than 1 μm, and multimode will require that axial deviation is less than 4 μm; 2, product is wear-resistant, repeatedly can repeat plug; 3, termination easily processes, and can grind to form sphere, tiltedly sphere; 4, product is anti-aging, more than 30 years service life; 5, material coefficient of thermal expansion and contraction is little, and environmental adaptability is strong.
Because the measure of precision for ceramic insertion core requires higher, therefore need to carry out attrition process to ceramic insertion core, conventional grinders adopts U.S.'s grinder, and grinder running orbit is figure of eight track, and face machined flat easily occurs white point, blackspot, line under 400 times of magnifying glasses; When detecting with 3D, the grinding object of 85% is defective.Conventional ceramic lock pin is first remove photoresist with carborundum in grinding technics, time 60S; Again with the pouncing paper corase grind time 60S of 6 μm; Use the pouncing paper fine grinding time 60S of 3 μm again; Again with the pouncing paper fine grinding time 60S of 16 μm; Finally carry out polishing time 60S with ADS; And it is not high to grind yield.
Summary of the invention
The object of the invention is to the shortcoming overcoming prior art, provide a kind of and grind that qualification rate is high, grinding efficiency is high, save grinding-material and the low grinding technics based on built-in type quick connector ceramic insertion core of production cost.
Object of the present invention is achieved through the following technical solutions: based on the grinding technics of built-in type quick connector ceramic insertion core, it comprises the following steps:
Prepare before S1, grinding: by four of corner pressure grinding machine pressurization stress point furnishing corner relative status, make four stress point uniform force of pressurizeing;
S2, sabot: inserted by ceramic insertion core in abrasive disk, guarantee that ceramic insertion core exposes abrasive disk and the height exposed of each ceramic insertion core is identical;
S3, grinding, specifically comprise following sub-step:
S31, to remove photoresist: remove photoresist to ceramic insertion core with the diamond lap paper of 30 μm, the duration is 20 ~ 40s;
S32, corase grind: the pouncing paper fixing 9 μm on grinding pad, arranging grinder running orbit is " O " font, and rotating speed is 60 ~ 120r/min, corase grind 30 ~ 40s;
S33, fine grinding: taken out by the pouncing paper in step S32, retighten the pouncing paper of 1 μm, arranging grinder running orbit is " O " font, and rotating speed is 160 ~ 200r/min, fine grinding 30 ~ 40s;
S34, polishing: carry out polishing by ADS polished silicon wafer, arranging rotating speed is 160 ~ 200r/min, polishing 30 ~ 40s;
S4: detect: the face machined flat of ceramic insertion core is placed on respectively on 400 times of magnifying glasses and 3D interferometer and detects, after qualified, obtain product.
Lapping liquid in described step S32 and step S33 is distilled water.
The step of grinder maintenance is also comprised after step S3.
The present invention has the following advantages:
1, the present invention has selected the grinder of domestic corner pressurization, and reduce production cost, grinder running orbit is " O " zag trajectory, and face machined flat is more than 93% qualified under 400 magnifying glasses, and when detecting with 3D, the grinding object of more than 90% is qualified.By continuous test, ceramic insertion core is first remove photoresist with the diamond lap paper of 30 μm, then roughly grind with rough lapping paper in grinding technics; Use the fine grinding of fine lapping paper again, finally carry out polishing with ADS, a grinding-material of saving, single set product also a saving milling time simultaneously, improves grinding yield simultaneously.
2, ADS polished silicon wafer on the one hand self has the more common polished silicon wafer longer life-span, and it can realize the minimized of face machined flat cut and spot on the other hand, there will not be simultaneously and sticks together phenomenon.
