Definitions
- the present invention relates generally to the supports for optical lens, and, more particularly, for ophthalmic lens.
- any ophthalmic lenses As is known, it is usual, after their manufacture, to apply any ophthalmic lenses to any treatment, in order to give them particular characteristics, and, for example, abrasion resistance properties and / or anti-reflective properties.
- ophthalmic lens is meant here, more particularly, conventionally, a puck from which is then derived, by trimming, a spectacle lens to be mounted on any spectacle frame. Most often, this puck has, peripherally, a circular contour, but it is not always necessarily so.
- the application of a treatment to an ophthalmic lens most often involves the deposition of at least one layer of material on the surface thereof, and it is obviously important that this deposition do with very good uniformity.
- This treatment in practice involves a rotation of these ophthalmic lenses at a relatively moderate speed, which is of the order of 50 revolutions / min, relative to the axis of rotation of the collective support on which the assembly is then attached.
- the individual support comprises, overall, a base, and, carried by the latter, for gripping such an ophthalmic lens by its edge, three support pads, one of which is fixed relative to to the base while possibly being adjustable in position relative thereto, and the other two of which are each individually carried by elastically deformable arms themselves carried by the base.
- this base is in the general form of a generally circular contour ring whose radial dimension, that is to say the dimension according to its thickness, and therefore, according to the plane of its edges, is very much lower than its height, that is to say its dimension along a perpendicular to this plane.
- spin coating according to which the substrate to be treated is rotated and a small amount of the material to be used is deposited on its surface.
- the speed of rotation of the substrate during the spreading phase of this material is relatively high, being in practice always greater than 1500 revolutions / min, for ensure an adequate distribution of the material over the entire surface of the substrate.
- a general subject of the present invention is a support for an optical lens capable, on the contrary, of ensuring simply a suitable maintenance of such an optical lens, even within an apparatus implementing the technique of deposition by "spin coating".
- This support for optical lens which is of the kind comprising at least a first base, and, carried by the latter, for the maintenance of such an optical lens, at least three support pads is generally characterized in that, the base comprising, for its own seat, a support surface, which is planar, and whose peripheral contour is generally circular, its radial dimension along any radius of this support surface is at least equal to its axial dimension along a perpendicular to the plane thereof.
- the support can in particular be fixed by its sole bearing surface on a rotating plate of "spin coating” apparatus forming a pneumatic suction cup, that is to say having a plurality of suction orifices maintaining the base against said plate by suction from its bearing surface.
- the present invention also relates to a method of implementing this support, characterized in that it involves a rotation of this support and of the optical lens which it carries at a speed of rotation greater than 500 rpm.
- a rotation of this support and of the optical lens which it carries at a speed of rotation greater than 500 rpm.
- at least one is fixed relative to the base, and another, at least, is carried by an elastically deformable element itself carried by the base.
- At least two of the support pads that the support for optical lens according to the invention comprises are fixed, only the third of these support pads being carried by an elastically deformable element.
- the support studs that the support for optical lens according to the invention comprises take place along an eccentric circumference relative to the periphery of the base, that is to say relative to the periphery of the surface. the latter, the center of this circumference being located closer to the fixed support stud (s) than the center of this periphery.
- the base of the support for optical lens according to the invention is perforated by a central opening, and the fixed support stud (s) are at the edge thereof, while the support stud (s) carried by an elastically deformable element extend in the very contour of this central opening.
- the relative thinness of the base of the support for an optical lens according to the invention is also advantageously favorable for storing this support by its edge in any storage bin, of basket type, comprising, from place to place, following a regular pitch, grooves in favor of each of which can be engaged such a support.
- the three support pads are fixed on the base and each have a radial support face and an axial support face, the axial support faces of the different pads providing at the periphery of the lens a seat along a given plane parallel to the bearing surface of the base. This results, in particular at high rotational speeds, more rigid and more reliable support of the lens.
- the base being in the form of a solid disc, the seat plane offered by the axial bearing faces of the studs extends slightly away from this other face of the base.
- the base being in the general form of a perforated disc by a central opening delimited by an inner border substantially of the same shape and the same dimension as the lens, the support pads are each made in two parts, with a first part which projects from the other face of the base and has the radial bearing face of the stud concerned and a second part which extends radially from the inner edge of the base.
- the base being in the form general of a perforated disc by a central opening delimited by an inner border substantially of the same shape and the same dimension as the lens
- the support pads are each made in two parts, with a first part which projects from the other face of the base and has the radial bearing face of the stud concerned and a second part which extends radially from the inner edge of the base.
- each stud is made in one piece with the base.
- These beveled axial bearing faces thus provide the lens with a pseudo-conical seat which reduces its contact with these axial bearing faces to a line, or even a single point, situated on its peripheral edge.
- the support comprises a second base similar to the first, provided with at least three support pads for holding the lens and comprising, for its own seat, a flat support surface whose peripheral contour is generally circular, its radial dimension along any radius of this support surface being at least equal to its axial dimension along a perpendicular to the plane thereof;
- the studs of the second base have axial bearing faces providing the lens with a seat along a plane parallel to the support surface of the base for its own seat;
- the two bases are provided with means of their superimposed assembly, with the bearing surface of each base turned opposite to the other base, so that the two seats offered by the axial bearing faces of the pads of the two bases take the periphery of the sandwich lens.
- the lens is thus sandwiched between the two bases which each offer it, by the axial bearing faces of their studs, a seat in a plane parallel to their bearing surface.
- the entire support, with its two bases and the lens placed between it, can thus be turned over for the successive treatment of the two faces of the lens.
- the support is arranged so that the first base is located below the first, with its bearing surface resting on the turntable of the apparatus, the lens resting on the axial bearing faces of the pads of this first base.
- the entire support is turned over so that its second base is found below the first, with its support surface resting on the turntable of the apparatus.
- the lens then rests on the axial bearing face of the studs of this second base and its second face can be treated.
- the two planes of the seats offered by the axial bearing faces of the pads of the two bases are distant from each other by a distance slightly greater than the thickness of the lens, so that the latter has a certain axial clearance between the two seat planes associated with the two bases.
- the upper face of the lens is entirely disengaged from the axial bearing faces of the studs of the base which are located above it and is only in contact by its face. lower, which is not treated, with the axial bearing faces of the studs of the base which rest on the turntable of the "spin coating" apparatus.
- the means of assembling the two bases one on the other involve the support pads.
- the support pads are thus made to exercise a second function contributing to the assembly of the two bases.
- the support pads of the first base each have a lug which extends parallel to the central axis, opposite the support surface of the base , and which carries the radial bearing face of the stud concerned
- the studs of the second base each comprise a terminal carrying the axial bearing face of the stud concerned and having an axial housing for receiving the lug of a stud correspondent of the first base.
- axial of their stud is determined by the stop of the free end of the pins of the studs of the first base against a bottom of the housing of the terminals of the studs of the second base.
- the axial bearing faces of the pads of the second base are beveled.
- the fact that the axial bearing faces of the studs of the second base are bevelled makes it possible to offer the lens a pseudo-conical seat which reduces its contact with these faces d 'axial support to a line, or even to a single point, located on its peripheral edge. Its underside, which may have just been treated before the support is turned over, is thus preserved from any contact which could damage its surface treatment.
- each of the two bases is in the general form of a perforated disc by a central opening delimited by an inner border substantially of the same shape and the same size as the lens.

- the radial dimension D 1 is between 50 and 60 mm, and the axial dimension D2 between 1 and 5 mm.
- the base 1 3 is a flat and full disc, the lower surface of which forms the bearing surface 1 6. Let C1 be its center.
- this is the center of the peripheral contour P1 of its support surface 1 6, and it corresponds to the center of rotation of the support 1 2.
- the fixed support pads 1 4A are cylindrical bosses, whose cross section is circular, and whose generatrixes extend perpendicularly to the base 1 3.
- the two fixed support pads 14A are identical to each other, and these are straight cylinder sections which are each duly attached to the base 1 3 by any means of fixing 1 8, a screw for example, figure 3.
- the elastically deformable arm 1 5 carrying the third support pad 14B is anchored at its root in one of the fixed support pads 1 4A.
- this elastically deformable arm 1 5 is formed by a leaf spring whose width extends perpendicular to the plane of the bearing surface 1 6 of the base 1 3.
- this elastically deformable arm 1 5 is fitted, at its root, into the fixed support stud 14A which carries it, by means of a groove 20 of this fixed support stud 14A, and it extends freely cantilevered from the latter, along a contour which is, globally, a circular arc contour, and along a circular sector whose angle at the center is greater than 45 °, being for example of the order of 90 °.
- the support stud 1 4B thus carried by an elastically deformable arm 1 5 is integral with it, forming a single piece with this elastically deformable arm 1 5.
- the support stud 14B is simply formed by a square return to the free end of the elastically deformable arm 1 5, directed towards the center C1 of the base 1 3.

- the eccentric ent thus intervening between the center C2 of the circumference P2 on which the support pads 14A, 14B lie at rest and the center C1 of the peripheral contour P1 of the support surface 1 6 of the base
- 1 3 is between 1 and 5 mm, preferably being of the order of 1 to
- the base 1 3 is for example metallic, and it is the same for the elastically deformable arm 1 5.
- the base 1 3 can be made of aluminum. But it can also be made of synthetic material, if the temperature allows it. As for the fixed support pads 14A, they can for example also be made of synthetic material, if the temperature allows.
- the optical lens 10 to be maintained is simply inserted, by its edge 1 1, between the fixed support pads 14A and the support pad 14B carried by an elastically deformable arm 1 5, and, under the bias of the latter, it comes to bear positively against the support pads 14A fixed along a generator of each of these.
- the radial force deployed for this purpose by the elastically deformable arm 1 5 is between 1 and 1 0 N, preferably being of the order of 2 N.
- the base 1 3 is perforated by a large central opening 23, and therefore it has the general shape of a washer.
- the bearing surface 1 6 is then formed by its lower or upper surface.

- the support stud (s) 14B carried by an elastically deformable arm 1 5 extending in the very outline thereof.
- the fixed support pads 14A extend entirely on the same side of the base 1 3, and the same is true for the support pad 1 4B carried by an elastically deformable arm 1 5.
- the fixed support pads 1 4A are each individually secured to a flange 24 by which they are attached to the base 1 3. As before, these are straight and smooth cylinder sections . As a corollary, in the embodiment shown, between its root and the support stud 14B which it carries, the elastically deformable arm 1 5 is folded back on itself, following in practice a V-bend.
- the elastically deformable arm 1 5 is secured, at its root, to a flange 25 by which it is attached to the base 1 3, in the manner of the support pads 1 4A fixed.
- this flange 25 may have an extension 26, which extends circularly along the base 1 3 on the side along which the arm itself extends elastically deformability 1 5, to possibly counterbalance the latter.
- the support stud 14B carried by the elastically deformable arm 1 5 is in one piece with the latter, being formed by a square return from its free end.
- the fixed support studs 14A extend on either side of the base 1 3, being simply attached, and secured, to the internal edge of the 'central opening 23 thereof.
- At least one of these fixed support pads 14A is notched over its entire height, and, if desired, the same is true for the associated support pad 14B.
- this support stud 14B also extends on either side of the base 1 3.
- the movable support stud 14B is carried by an elastically deformable element 1 5.
- this element 1 5 is in the form of a simple straight blade or slightly curved which cooperates by each of its two ends with the edge of the central opening 23 and which carries in its middle the movable support stud 14B.
- the blade 1 5 has two ends 27, 28 which are integral with the base 1 3 and which are for this purpose embedded in two corresponding mounting blocks 29, 30 attached to the base 1 3. More precisely, the end 28 of the blade 1 5 is not strictly embedded in the block 30, but enjoys freedom of movement in the longitudinal direction of the blade 1 5.
- the blade 1 5 can thus bending with a high elasticity stiffness proper to a firm hold of a lens between the movable support pad 14B and the two fixed support pads 14A.
- the movable support stud 14B is in the form of a straight cylindrical section, smooth or provided with asperities.
- the base 1 3 is a solid disc, as in the embodiment shown in Figures 1 to 4.
- this base 1 3 is stepped, with, in its central region, a part of greater thickness 1 3 ′, which carries the support pads 14A, 14B.
- the radial dimension D1 of this base 1 3 remains at least equal to its axial dimension D2.
- the arrangements are moreover substantially the same type as those described with reference to FIGS. 1 to 4.
- the angle at the center of the circular sector along which the elastically arms deformability 1 5 is much less than 90 °, being for example of the order of
- the fixed support pads 14A have a smooth cylindrical base with a diameter greater than that of their upper part, which itself has grooves or notches.
- two support pads 14A, 14B are each carried respectively by an elastically deformable arm 1 5, only the third being fixed.
- the corresponding support 1 2 has been applied to the maintenance of an optical lens 10 whose contour is not circular.
- the support designated by the general reference 50, comprises a base 51 which is in the form of a solid disc having a central axis 52 and having a circular outline
- the base disc 51 has a first face 54, which is in practice its lower face and which constitutes a bearing surface for its own seat on the turntable of a "spin coating" apparatus.
- the base disc 51 has a radius very much greater than its thickness.
- the base disc 51 thus offers a sufficiently large bearing surface 54 to allow its stable fixing, for example by a pneumatic suction cup system fitted to the turntable of the "spin coating" apparatus.
- the base disc 51 has, on the side opposite its first face 54, a second face 55 which is in practice its upper face. Projecting from its upper face 55, the base disc 51 is provided with three identical support pads 56 which are regularly distributed around the central axis 52 to form a seat for holding the lens 10.
- each of the three studs 56 consists of a lug 57 in the form of a cylindrical bar, the lower end of which is embedded in the base disc 51 which extends parallel to the axis 52, that is to say -to say vertically, and of a block 59 which is fixed at its base on the upper face 55 of the base disc 51 and which has an upper face 60 cut in a bevel, that is to say extending in a oblique plane with respect to the faces 54 and 55 of the base disc 51, that is to say with respect to the horizontal.
- the upper face 60 of the block 59 is inclined at an angle of approximately
- the upper faces 60 of the blocks 59 are also arranged so as to converge in the direction of the central axis 52, towards the base disc 51, that is to say downwards, so as to provide the lens 10 a pseudo-conical seat.
- Each stud 56 thus has, for the lens 10, on the one hand a radial bearing face formed by the lateral surface of the lugs 57 and on the other hand an axial bearing face formed by the upper face 60 of the blocks 59.
- the axial bearing faces 60 presented by the blocks 59 offer the lens 10 a seat in a plane which is parallel to the upper face 55 of the base disc 51 and which is slightly raised relative to that -this.
- the lower face of the lens 10 is therefore kept at a distance from the upper face 55 of the base disc 51.
- Figures 1 4 to 1 6 there is shown yet another embodiment comprising two bases with fixed studs taking the sandwich lens.
- the support presented here designated by the general reference 70, comprises two bases in the general form of a disc, including a first base 71 and a second base 72.
- the two bases 71 and 72 are identical and have a common central axis 73 vertical.
- Each base 71, 72 has a circular contour 74, 75 centered on the axis 73, a first face 76, 77 and a second face 78, 79, opposite the first.
- the base discs 71, 72 are further perforated by a central opening delimited by an inner edge 80, 81 which is of substantially circular shape, centered on the axis 73 and which, more precisely, has substantially the same shape and the same dimension as lens 10.
- the inner edges 80, 81 of the base discs 71, 72 are not, however, strictly circular: they have rounded radial projections 82, 83 which are three in number here, regularly distributed around the central axis 73.
- Each of the base discs 71, 72 has three fixed support pads used to hold the lens 1 0 and arranged projecting from their second face
- the studs equipping the first base disc 71 differ from those equipping the second base disc 72.
- the studs of the first base disc 71 each consist on the one hand of a lug 85 formed by a cylindrical bar embedded at one of its ends in the base disc 71 and extending parallel to the central axis 73, that is to say vertically, and on the other hand of the corresponding projection 82 of the base disc 71.
- the lug 85 of each support stud 84 thus has a cylindrical peripheral surface which constitutes a radial support face for the edge 1 1 of the lens 1 0.
- the lug 85 of each stud 84 is arranged so that its peripheral surface, which constitutes the radial bearing face of the stud 84 concerned, is flush with an imaginary cylinder of axis 73 containing the inner edge 80 of the base disc 71. In this way, the lens 1 0 is housed almost without radial clearance between the lugs 85 of the studs 84.
- the projections 82 of the base disc 71 have meanwhile, in the continuity of the second face 78 of this base disc, an axial bearing face 86.
- the axial bearing faces 86 of the three projections 82 thus offer for the lens 10 sits in a horizontal plane which merges with that of the second face 78 of the first base disc 71. It is therefore understood that the projections 82 of the base disc 71 are an integral part of the pads 84 for holding the lens 10.
- the support pads of the second base disc 72 are in turn constituted by terminals 88 fixed by their base on the second face 79 of the second base disc 72, at the level of the radial projections 83.
- Each of these terminals 88 has at its top, that is to say opposite its base which is fixed to the base disc 72, an axial bearing face 89 which, in this case, is bevelled , that is to say which extends in an oblique plane with respect to the faces 77, 79 of the second base disc 76, that is to say with respect to the horizontal.
- this bevelled axial bearing face 89 forms with respect to the horizontal an angle a_ of approximately 50 °.
- the bevelled axial bearing faces 89 of the three terminals 88 converge towards the central axis 73 and towards the second base disc 72, so as to offer the lens 10 a pseudo-conical seat on which it rests exclusively by its edge peripheral, as will be better explained later.
- Each terminal 88 also has an axial housing arranged to receive with little play the lug 85 of the corresponding stud 84 of the first base disc 71.
- the pins 85 of the first base disc 71 and the terminals 88 of the second base disc 72 thus constitute homologous fitting means which produce an assembly of the two base discs 71 and 72 with a precise relative positioning of the latter. .
- the housings 90 of the terminals 88 are opening out on either side of the terminal and in particular at its base where it opens onto the second face 79 of the second base disk 72.
- the face 79 does it constitute the bottom of the housing 90 of the terminals 88.
- the first base disc 71 is arranged in the configuration shown in FIG. 14, that is to say horizontally, with its vertical central axis 73 and its bearing surface 76 facing downwards.
- the lens 10 is inserted between the pins 85 so as to come to rest on the axial support faces 86 presented by the radial projections 82.
- the underside of the lens 10 which has not yet been treated, and which is not yet subject to any treatment, is locally in contact with the projections 82.
- This contact is not, however, detrimental because, on the one hand, it extends over a very small surface, and on the other apart from the underside of the lens 10 is not coated with any surface treatment.
- the second base disc 72 is then placed over the first disc 71, as illustrated in FIG. 14.
- the second disc 72 is arranged horizontally, coaxially with the first disc 71, that is to say say along the central axis 73 common, with its bearing surface 77 facing upwards, the faces 78 and 79 of the two base discs 71 and 72 being opposite.
- the second disc 72 is wedged angularly, so that the housings 90 of the terminals 88 are substantially wedged on the axes of the lugs 85 of the studs 84 of the first base disc 71.
- the terminals 88 can then be fitted onto the lugs 85.
- the free end of the lugs 85 abuts in the bottom of the housings 90 of the terminals 88, that is to say against the face 79 of the second base disc 72 , without the axial bearing faces 89 of the terminals 88 coming into contact with the lens 1 0.
- the upper face of the lens 1 0 is thus preserved from any contact with the second base disc 72.
- the entire support, with its superimposed bases, and the lens 10 between them, can then be placed, in the configuration illustrated in FIGS. 14 and 15, on the turntable of a "spin coating" apparatus, with the bearing surface 76 of the first base disc 71 resting on this plate.
- the first face of the lens 10 which faces upwards can then be treated.
- the entire support with the lens is turned over and the bearing surface 77 of the second base disc 72 is placed on the rotating plate of the "spin coating" apparatus.
- the lens 10 which enjoys a certain clearance between the seat planes formed by the axial support surfaces associated with the two bases, descends slightly to come to rest on the axial support faces 89 presented. by the terminals 88 of the second base disc 72.
- the second face of the lens which is now oriented upwards, is then released from any contact with the first base disc 71.
- the other face of the lens 10 which is turned downwards and which has just undergone a treatment, rests on the axial bearing faces 89 in a bevel only by a line or a simple point of support situated on its periphery.
- This face of the lens 10 is therefore preserved from any contact with the second base disc 72, as can be seen in FIG. 1 6.
- the surface treatment which has just been deposited on this underside of the lens 10 therefore does not risk being damaged.
- the second face of the lens 10 which faces upwards can then be treated.
