Definitions

  • the present invention relates to a method of trimming an ophthalmic lens to a desired contour, for mounting in a spectacle frame.
  • It relates more specifically to the determination of a locking position of the lens on a locking medium on which the lens is maintained during its trimming.
  • This method is particularly suitable for trimming ophthalmic lenses whose contour has a complex shape, including negative curvature zones.
  • an ophthalmic lens for mounting on a circled, semi-rimless or no-circle (or "pierced") spectacle frame is achieved by acquiring the desired contour according to which the ophthalmic lens is to be cut off to fit to the shape of this eyeglass frame.
  • This contour is positioned on the lens according to the optical reference of the lens so that the latter is, when worn, properly positioned in front of the eyes of the wearer. The lens is then cut off following this desired contour.
  • ophthalmic lenses intended to be cut off according to contours of complex shapes including, for example, curved zones towards the center of the lens, called zones of negative curvature.
  • These negative curvature zones generally correspond to decorative details of the contour of the lens and need to be machined by a tool of diameter less than the diameter of the grinding wheel commonly used to cut the lens. We for example, uses a milling tool of a few millimeters in diameter.
  • the internal cutting limit is defined around the blocking support and corresponds to the zone around this support in which the machining tool in question can not access, because of the risk of interference between the tool (or the door tool) and the locking bracket.
  • the invention it is possible to detect, even before the setting of the blocking support on the lens (generally at the optical center or at the boxing center of the lens), the risks of interference between the tool of machining and blocking bracket.
  • envelope will be used to designate the surface that delimits a volume considered.
  • the envelope of an object in motion will in particular designate the surface in which is circumscribed all the positions of the object when it moves according to the movement considered.
  • the technical part of the optician's profession is to mount a pair of ophthalmic lenses on a frame selected by the future wearer of the pair of glasses.
  • This clipping operation is generally performed in three successive stages of roughing, finishing and finishing.
  • the roughing step consists of bringing the initial contour of the lens back to a near or identical contour of the desired contour.
  • the finishing operation consists of beveling the edge of the lens if it is intended to be mounted on a circled spectacle frame, or to groove the edge of the lens if it is intended to be mounted on a frame of semi-rimmed glasses.
  • the finishing step consists of polishing and chamfering as necessary the sharp edges of the edge of the lens.
  • the clipping method according to the invention applies here to all of these steps.
  • an ophthalmic lens 10 has two front 14 and rear 15 optical faces, and an initially circular wafer 16 which should be returned to the shape of the desired contour, so that the ophthalmic lens can then be attached to the selected eyeglass frame.
  • the method according to the present invention applies to any type of contour, regular or not. However, it applies particularly advantageously to ophthalmic lenses to be cut on desired contours of irregular shapes, and to assemble with frames of pierced type spectacles (In which the branches and the bridge of the frame have means for fixing to drilling holes made in the lenses).
  • the desired contour 11 considered in projection in a general mean plane of the ophthalmic lens not yet cut-off, comprises a regular lower sector and an irregular upper sector AD.
  • This upper sector is formed of several complex regions delimited respectively by the points A, B, C and D.
  • Each complex region A-B, B-C, C-D has one or more zones of negative curvature. These areas of negative curvature are areas in which the desired contour 11 is concave.
  • boxing center forms the origin of the benchmark of the reference of the ophthalmic lens.
  • the average plane of the ophthalmic lens is defined as the plane which contains the circular rear edge of the lens which has not yet been cut off.
  • the desired contour 11 then corresponds to the projection in this mean plane of the three-dimensional contour along which the lens must be cut off.
  • this ophthalmic lens 10 To cut off this ophthalmic lens 10, it is placed in a machining device 200 known in itself, such as that described in the document W02008 / 043910 .
  • this computing and control device 100 is integrated in the electronic and / or computer system of the grinder 200.
  • the support means 210 of the ophthalmic lens 10 here more specifically comprise two shafts and rotation drive 211 of the ophthalmic lens 10 to be cut. These two shafts 211 are aligned with each other along the blocking axis A2.
  • Each of these shafts 211 has a free end which faces the other, one of which is equipped with a locking nose 214 of the ophthalmic lens 10 and the other of which is equipped with a receiving means 213. a locking accessory 215 of the lens (prepositioned on the lens at the time of its blocking).
  • This locking accessory is conventionally positioned on the ophthalmic lens at a given point and with a given orientation, which makes it possible to locate the position of the reference frame of the ophthalmic lens relative to the reference frame of the frame 203 of the machining device 200.
  • this blocking accessory 215 comprises a body arranged to cooperate with the corresponding shaft 211 of the grinder 200, and an adhesive patch arranged to stick to the front optical face 14 of the ophthalmic lens.
  • the nose and the locking accessory 214, 215. It is then possible to define around the axis of blocking A2 a surface, called inaccessibility envelope B1, in which it is not possible to machine the ophthalmic lens 10. Since the nose and locking accessory 214, 215 here have the same contour of known transverse dimension (typically, a circular contour of known or rectangular diameter of known sides), the inaccessibility envelope B1 is defined as the cylinder of revolution about the locking pin A2, which has a diameter equal to that of the nose and locking accessory 214 215 (or slightly greater than this diameter, given the possible deformations of these nose and locking accessory).
  • a first of the two shafts 211 is fixed in translation along the blocking axis A2.
  • the second of the two shafts 211 is conversely mobile in translation along the blocking axis A2 to achieve the compression in axial compression of the ophthalmic lens 10 between the two shafts.

During machining of the lens, these tool holders are therefore not likely to interfere with the 211 locking shafts of the ophthalmic lens.
  • the cutter 230 is however supported by a mandrel 240, itself supported by the finisher 235, whose dimensions (transverse to the axis A6) are greater than those of the cutter. More specifically here, the cutter 230 is positioned in such a way on the finishing module 235 that the latter may interfere with the locking shafts 211 of the ophthalmic lens.

  • the safety shells of the large grinding wheel 220 and the grinder 231 are formed by their cutting shells since their tool holders are not likely to interfere with the shafts 211 for blocking the ophthalmic lens.
  • the security envelope B2 must never intersect the envelope of inaccessibility B1 in order to avoid, on the one hand, any risk of machining of the nose and locking accessory 214, 215, and, on the other hand, any risk of interference between the tool in question (or the door tool) and the locking shafts 211 of the ophthalmic lens.

  • the algorithm calculates for this purpose the position of the cutting envelope 30 of the grinding wheel 220 when it is tangent to the contour at this point. This position corresponds to the position of the grinding wheel 220 when it is in position to machine the lens 10 according to the desired contour 11 at this point.
  • the algorithm searches for the points of the desired contour 11 that are inside this first cutting envelope, that is to say located on the side of the arc corresponding to the wheel 220, if exists. These points correspond to the additional points trimmed by the grinding wheel 220 when it is machining the lens 10 at the considered point of the desired contour 11.

It is therefore understood that by placing the locking accessory 215 on the ophthalmic lens 10 in such a way that it is centered on the boxing center P 1 , it will appear during the machining of the lens a problem of interference between the shafts 211 of locking the lens and the tools or tool holders of the grinder 200.

    - d3) die Schritte d1) und d2) wiederholen, solange der Schritt d2) ein Schnittstellenergebnis (Q'11 - Q'12) ungleich null ergibt.
  4. Verfahren nach einem der Ansprüche 1 und 2, bei dem der Schritt d), wenn die in Schritt c) berechnete Schnittstelle (Q11 - Q12, Q21 - Q22) ungleich null ist, folgende Unterschritte umfasst:
    - d'1) eine Vielzahl von alternativen Einklemmpositionen ermitteln, die sich von der ursprünglichen Einklemmposition (P1) unterscheiden,
    - d'2) für jedes Werkzeug und für jede der alternativen Einklemmpositionen berechnen, ob mindestens ein Teil der gewünschten Kontur, so wie in der jeweiligen alternativen Einklemmposition positioniert, eine Schnittstelle ungleich null mit der dem jeweiligen Werkzeug zugeordneten internen Schnittgrenze aufweist,
    - d'3) unter diesen alternativen Einklemmpositionen die veränderte Einklemmposition auswählen.
  5. Verfahren nach Anspruch 4, bei dem im Schritt d) die veränderte Einklemmposition als die Einklemmposition des Brillenglases in der Einklemmhalterung definiert wird, die unter den alternativen Einklemmpositionen der ursprünglichen Einklemmposition am nächsten liegt.
  6. Verfahren nach Anspruch 4, bei dem im Schritt d) die veränderte Einklemmposition als die Einklemmposition des Brillenglases in der Einklemmhalterung definiert wird, die unter den alternativen Einklemmpositionen der dem Schwerpunkt der gewünschten Kontur (11) am nächsten gelegene Position ist.
  7. Verfahren nach einem der vorausgehenden Ansprüche, bei dem man im Schritt c) den Radiusabschnitt (S1, S2) um die ursprüngliche Einklemmposition (P1) berechnet, der sich innerhalb des Schnittpunktes (Q11-Q12, Q21-Q22) befindet und die größte Länge aufweist und bei dem im Schritt d) die veränderte Einklemmposition (PN) aus mindestens einer Translation der ursprünglichen Einklemmposition (P1) entlang der Richtung des Radiusabschnittes (S1, S2) hervorgeht.
  8. Verfahren nach Anspruch 7, bei dem diese Translation über eine Distanz ausgeführt wird, die der Länge des Radiusabschnittes entspricht.
  9. Verfahren nach einem der Ansprüche 7 und 8, bei dem man im Schritt c), während mindestens zwei Schnittstellen (Q11-Q12, Q21-Q22) ungleich null zwischen der gewünschten Kontur (11) und jeder internen Schnittgrenze (12, 13) resultieren, für jeden Schnittpunkt (Q11-Q12. Q21-Q22) den Radiusabschnitt (S1, S2) um die ursprüngliche Einklemmposition (P1) berechnet, der sich innerhalb der relevanten Schnittstelle (Q11-Q12' Q21-Q22) befindet und die größte Länge aufweist und bei dem im Schritt d) die veränderte Einklemmposition (PN) aus mindestens einer Kombinierung von Translationen der ursprünglichen Einklemmposition (P1) entlang der Richtungen der Radiusabschnitte (S1, S2), die jeweils den mindestens zwei Schnittstellen (Q11-Q12, Q21-Q22) zugeordnet sind, hervorgeht.
  10. Verfahren nach einem der vorausgehenden Ansprüche, das für ein Brillenglas angewendet wird, das mittels einem zweiten Bearbeitungswerkzeug gebohrt oder mit einem Wellenschliff versehen werden soll, um in eine rahmenlose Brillenfassung montiert zu werden und welches umfasst:
    - einen Schritt zum Erzielen einer internen Schnittgrenze des zweiten Bearbeitungswerkzeugs, die im Referenzsystem der Bearbeitungsvorrichtung definiert ist,
    - einen Schritt zum Erfassen der Randpositionen der Zacken oder Bohrlöcher in einem der gewünschten Kontur zugeordneten Referenzsystem,
    - zwischen den Schritten d) und e) einen Berechnungsschritt, um zu ermitteln, ob die Ränder der Zacken oder Bohrlöcher mit der internen Schnittgrenze, die diesem zweiten Werkzeug zugeordnet ist, eine Schnittstelle ungleich null aufweist, wenn die gewünschte Kontur wieder in der endgültigen Einklemmposition positioniert ist, und
    - einen Schritt zum Ermitteln einer neuen endgültigen Einklemmposition, wenn eine Schnittstelle erkannt worden ist, die sich von der besagten endgültigen Einklemmposition unterscheidet und derart ist, dass zum einen die gewünschte, neu in die neue endgültige Einklemmposition positionierte Kontur, keine Schnittstelle mit der dem zweiten Werkzeug zugeordneten internen Schnittgrenze aufweist, und derart, dass zum anderen die Ränder der Zacken oder Bohrlöcher keine Schnittstelle mit dieser internen Schnittgrenze aufweisen.
