Description
Technical field
The present invention is the device of relevant grinding work-piece end face, the especially relevant tool of putting of settling optical fiber end face to be ground.
Background technology
Optical-fibre communications has been to reach the indispensable instrument of following communication science and technology at present, as the communication element of line communication system, needs signal wire and signal connector to connect together.Fiber Optical Communication System also needs the joints of optical fibre.The joints of optical fibre mainly are that optical fiber is passed the lasso that there is the hole centre, cling with the agent of sticking work to form again.This kind lasso can be plastic cement, glass or ceramic.To place resilient abrasive surface pressurization with the fiber end face of lasso, form the protrusion sphere through corase grind, fine grinding, polishing.This protrudes sphere must be the minute surface that does not have flaw.This optical axis that protrudes sphere can parallelly with the center line of optical fiber also may become a little oblique angle.
For the grinding of fiber end face, at least in fine grinding and when polishing, use the elastic grinding face in its process.As shown in Figure 1.The workpiece 1 that needs are ground places elasticity flour milling 2 tops, exerts pressure 3 above workpiece 1, makes elasticity flour milling 2 produce concave surface, and is ground out the workpiece 1 with protruding end face.Because the cross section of optical fiber is less, so corase grind, fine grinding and polish the required time and be approximately tens seconds to tens of second, it is short a lot of to grind required time than the traditional optical eyeglass.When grinding fiber end face, fiber end face is put each fiber end face severity of grind at one time on the tool, or in the relative short period, average severity of grind must be identical, otherwise have uneven phenomenon after grinding.
Basically, the wear intensity of workpiece is relevant with several factors, and is mainly for following two factors:
1. the average relative of flour milling and workpiece; And
2. the pressure size between flour milling and workpiece.
Traditional fiber end face grinds, and it is actionless that fiber end face is put tool, and flour milling then is to have rotation to add the motion of revolution.As shown in Figure 2, ψ is the rotation angle, and θ is the revolution angle, by No. the 485863rd, Taiwan patent announcement that the inventor invented, the mathematical analysis that " milling apparatus of fiber end face " disclosed learns, fiber end face is put on the tool certain and a bit with the average relative of abrasive surface is:
Average relative=(r
1)
2ψ
2+ R
2(ψ-θ)
2... (1), wherein
R: be the distance of the revolution center of circle to the rotation center of circle; ψ
ψ: the angular velocity of rotation;
θ: the angular velocity of revolution;
r
1: fiber end face is put certain some distance to the revolution center of circle on the tool.
In process of lapping, revolve round the sun usually angular velocity θ and spin velocity ψ are fixing.By (1) formula as can be known, the average relative of difference is different on fiber end face.And if r
1Identical, just with the revolution mid point be r then on the circumference in the center of circle
1Identical, if the pressure of each point is identical on this moment circumference, then the wear intensity of each point is identical on this circumference.If allow ψ=0, just abrasive surface has only revolution, does not have rotation, then average relative=R
2θ
2If this moment, fiber end face put that the pressure of each fiber end face and flour milling is uniform on the tool, then the wear intensity of each end face is identical.
Above-mentioned in addition patent proposes again, if abrasive surface is made strip, and make the abrasive grains on one side of strip thicker, and the another side particle is thinner.Through proper arrangement, it is uniform can making and be placed in fiber end face and the pressure between the flour milling of putting diverse location on the tool.Then fiber end face can be put tool by thicker the grinding and the polishing program of particle while sliding to the thinner thickness of directly once finishing of particle.
As shown in Figure 3.Several fiber end faces are put tool 4,5,6, on the abrasive surface 7 of strip, slide simultaneously.The particle of the flour milling 8 on the right is thicker, and the particle of the flour milling 9 on the left side is thinner.This invention can solve flour milling and put between the tool, and the light of diverse location is knitted the problem that the pressure of end face is evenly distributed.
Basically the uneven reason of pressure has two:
1. fiber end face is put the support point of tool, not on the force surface that the friction of fiber end face and flour milling is produced.Thereby generation torsion, make and put tool, and produce the uneven phenomenon of pressure.
If fiber end face put tool clamped fixing, the then abrasive surface and the not parallel uneven phenomenon of pressure that also can produce of putting tool.
See also Fig. 4, shown in Figure 5.Known Fiber Optic Polishing Machines comprises that abrasive surface 21, fiber end face lasso 22, fiber end face are put tool 23, pressurization fixed bar 24 is formed.The end to be ground of optical fiber 25 is incorporated in the fiber end face lasso 22.When optical fiber 25 end faces and flour milling 21 had relative motion, this fiber end face was put tool 23, is subjected to a horizontal strength in the end.But fulcrum is in the position of contact point 31 or contact point 32 at this moment, therefore fiber end face is put tool 23 and is subjected to an anticlockwise torsion, produce heeling condition as shown in Figure 5, make fiber end face 251 low than fiber end face 252, just end face 251 suffered pressure want big than end face 252.
In order to address this problem, No. 5216846, U.S. Pat discloses to keep the distance between workpiece and the flour milling with spacer (spacer).Because flour milling is the elasticity flour milling, keep-up pressure so keep at a distance to be.This method, because some uneven pressure is born by spacer, thus have some improvement, but the not change of its basic structure, torsion still exists, so the unequal factor of pressure still exists.
No. 6039630 announcements of United States Patent (USP) US utilize pressure sensor to remove to measure instantaneous pressure in addition, come the inequality of compensatory pressure again with the method for electronics control spring.
U.S. Pat 6077154, US 5351445 etc. propose fiber end face is clamped fixing design, as shown in Figure 6 in addition.Wherein fiber end face is put tool 41 in conjunction with most fiber clamps 42, fiber clamp 42 fiber clampings 43.Anchor clamps 42 fixed fiber end faces are put the top of tool 41 in flour milling 45.This design because fiber end face put tool 41 clamped fixing, so do not have the tilt problem that produces because of torsion.But a problem is arranged, walk to be clamped fixing because put tool 41, and the direction of flour milling 45 is also fixed, so general situation is that putting that tool 41 and flour milling 45 are inevitable can be not parallel very accurately.At this moment common way is to adjust to make the angle of putting the fixing anchor clamps 42 of tool 41.But not the contact of a nature like this, always have not parallel.In addition, this design, the pressure between optical fiber 43 end faces and the flour milling 45 is exerted pressure upward by following, and this mode is too complicated first, moreover inconvenient robotization.If the design of abrasive surface is as shown in Figure 3 in addition, strip, and be that several fiber end faces are put tool, on the abrasive surface of this strip, slide simultaneously, then the pressure that will keep each to put the fiber end face of diverse location on the tool is that is just more difficult uniformly.
When pressure is unequal in addition, except the grinding quality that makes fiber end face not, especially, if put on the tool, grind very a large amount of fiber end faces simultaneously, the less part of pressure must need to spend the more time to grind to finish, thereby has influenced grinding efficiency, so when the fiber end face that once grinds simultaneously the more the time, it is important whether pressure distribution evenly just heals.
Summary of the invention
Via the analysis of aforementioned known techniques, the inventor invents optimal fiber end face and puts the principle of design of tool and be:
1. fiber end face is put tool and cannot be clamped fixingly, and to put tool must be that nature contacts with abrasive surface.If just abrasive surface has any swinging up and down, put tool and also will and then swing up and down, and when swinging up and down, if it is also uniform to put the mean pressure of the end face of diverse location on the tool.
2. the formed plane of fiber end face in process of lapping promptly is that abrasive surface forces in the force surface of putting tool.Because in process of lapping, to put tool be not along with abrasive surface moves to fiber end face in principle, or rotate.Put the fulcrum of tool so need one of design or several fiber end faces.For making pressure even, these fulcrums must not move or rotate along with abrasive surface to keep fiber end face to put tool on this force surface.
