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 following indispensable communication tool at present.The optical fiber connector that optical-fibre communications is used, its primary structure make optical fiber 11 pass lasso 12 as shown in Figure 1, stick with adhesive agent to form again.This kind lasso 12 can be plastics, glass or ceramic.The protrusion sphere 121 of lasso 12 end faces then is to pressurize on the elastic grinding face, forms through corase grind, fine grinding, polishing.This protrudes sphere 121 must be the cambered surface that does not have flaw.This optical axis that protrudes sphere 121 can parallelly with the center line of optical fiber 11 also can become a little oblique angle.
Tradition is ground the method for fiber end face, is to make the fiber end face transfixion, and flour milling is ground fiber end face do the motion that rotation adds revolution.Learn by No. 485863 " milling apparatus of fiber end face " disclosed mathematical analysis of TaiWan, China patent announcement that the inventor got permission.Add revolution if the motion mode of abradant surface is rotation, then put on the tool at fiber end face, fiber end face only should be arranged on the circumference.If but have only revolution, and there is not rotation, the wear intensity that then whole fiber end face is put on the tool and had a few all is identical.Fiber end face can on average be placed in whole fiber end face and put on the tool.Above-mentioned in addition patent is open again, if abradant surface is made strip, and make strip flour milling abrasive grains on one side thicker, and the another side particle is thinner, as shown in Figure 2, several fiber end faces is put tool 2,3,4 slide on the abradant surface 5 of strip simultaneously.The particle of the flour milling 6 on the right is thicker, and the particle of the flour milling 7 on the left side is thinner.Through proper arrangement, it is uniform can making and be placed in fiber end face and the pressure between the abradant surface 5 of putting diverse location on the tool.Then fiber end face can be put tool 2,3,4 by thicker thinner of abradant surface 5 particles, once finish thickness mill and polishing program continuously while sliding to particle.So if the uniform problem of pressure can solve between fiber end face and the abradant surface, in theory, can grind very a plurality of fiber end faces simultaneously.
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 produces torsion, makes and puts tool, and produce the uneven phenomenon of pressure.
If fiber end face put tool clamped fixing, abradant surface and put the not parallel uneven phenomenon of pressure that also can produce between the tool then.
See also Fig. 3, shown in Figure 4.Known Fiber Optic Polishing Machines comprises that abradant 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 4, 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 utilizes spacer (Spacer) to keep distance between workpiece and the flour milling.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.
United States Patent (USP) is US6039630 number in addition, utilizes pressure sensor to remove to measure instantaneous pressure, comes the inequality of compensatory pressure again with the method for electronics control spring.
U.S. Pat 6077154, US5351445 etc. propose fiber end face is clamped fixing design, as shown in Figure 5 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 is clamped fixingly because fiber end face is put tool 41, does not inscribe so do not have between the inclination that produces because of torsion.But a problem is arranged, clamped fixingly 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 automation.If the design of abradant surface is as shown in Figure 2 in addition, strip, and be that several fiber end faces are put tool, on the abradant 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.
No. the 222915th, the TaiWan, China patent of invention of getting permission the inventor " optical fiber end surface grinding device " in addition, it is disclosed that to reach two average principles of pressure as follows:
1. fiber end face is put tool and cannot be clamped fixingly, and to put tool must be that nature contacts with abradant surface.If just abradant 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 average 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 abradant surface forces in the force surface of putting tool, because in process of lapping, to put tool be not along with abradant 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 abradant surface to keep fiber end face to put tool on this force surface.
See also shown in Fig. 6 A, Fig. 6 B.Utilize the designed tool of putting of this principle to comprise as follows.This puts tool, comprises that the centre of a body 50 has the holddown groove 51 that is recessed in body 50 belows, with a ccontaining fixed bar 52; The body 50 outer sides that enclose have the storage tank 53 of plural number symmetry respectively with ccontaining counterweight 54.Storage tank 53 can be respectively arc groove shape, cylindric or long groove shape.Body 50 can be distinguished rounded and square.Body 50 and in conjunction with a plurality of anchor clamps 500.Each anchor clamps 500 is in conjunction with at least one fiber end face lasso 55, with in conjunction with optical fiber to be ground 56.Lasso 55 belows have flour milling 57, and flour milling 57 is incorporated into pedestal 58 tops.Fixed bar 52 upper ends are in conjunction with support body 59.The bottom of fixed bar 52 has the outstanding contact site 521 of external diameter.Contact site 521 and holddown groove 51 are corresponding male and fomale(M﹠F), as corresponding polygonal design, make between fixed bar 52 and the holddown groove 51 can not rotate.The fixed bar 52 of present embodiment is not bestowed body 50 pressure down.The function of fixed bar 52 just limits body 50, and it can not be moved or rotate.
The feature of originally putting tool is, in the process of lapping, fixed bar 52 only contacts with holddown groove 51 in contact site 521, and the contact-making surface of the face machined flat of contact zone and plural optical fiber 56 and flour milling 57 approximately at grade, make the support point of body 50, on the force surface that 57 frictions of optical fiber 56 bottoms and flour milling are produced, and can not produce torsion body 50 is tilted, produce the uneven phenomenon of pressure.
Utilize counterweight 54 to impose body 50 pressure down, the pressuring method that the face machined flat that makes optical fiber 56 and 57 one-tenth of flour millings contact naturally.When flour milling 57 swings up and down, body 50 also and then swings up and down, thereby contact pressure between face machined flat and the flour milling 57 of the optical fiber 56 of diverse location on the body 50, can keep identical size, make the face machined flat of same batch job obtain identical grinding shape, to promote the speed and the quality of grinding.
See also shown in Figure 7.Another embodiment of above-mentioned TaiWan, China patent of invention puts tool, its body 60 peripheries have the storage tank 61 of a plurality of symmetries with ccontaining counterweight 62, make body 60 have the strength that the end face that makes plural optical fiber 63 presses down flour milling 64, thereby body 60 is the pressuring method that nature contacts with flour milling 64.But body 60 does not have the holddown groove 51 of body 50 shown in Fig. 6 A, and the fixed bar 65 that has plural symmetric design below body 60 sides, and fixed bar 65 bottoms have outstanding contact site 651, place respectively in the holddown groove 661 of support body 66.The lower end of holddown groove 661 has outage 662, falls into the liquid in the storage tank 661 when grinding to discharge.The contact-making surface of contact site 651 and holddown groove 661, with the contact-making surface of the bottom of plural optical fiber 63 and flour milling 64 on same plane, the support point that makes body 60 is on the force surface that the bottom and the flour milling 64 of optical fiber 63 produced, therefore can not produce torsion body 60 is tilted, and produce the uneven phenomenon of pressure.
Present known fiber end face grinder mostly once can only grind 12 end faces, and is also more
But have only 48 or 64.If the following once very a large amount of end face of grinding that needs, if must will spending the more time to grind, the less part of pressure inequality and pressure finishes, thereby 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.
