Definitions

  • the present invention relates generally to the manufacture of optical lenses such as ophthalmic and / or sunglass lenses, objective lenses, and the like. It relates in particular to the blocking of such a lens during its surfacing or control and for this purpose relates to a pneumatic locking support which is intended to be fixed on the nose of one or more machine tools or measuring devices or control and which serves to ensure the locking on these machines or devices of the lens or a semi-finished blank of this lens.
  • a semi-finished lens also known as a preform or preform
  • a preform or preform is obtained by molding the synthetic or inorganic material that has been chosen to constitute the base substrate of the lens.
  • the molded semi-finished lens is surfaced on one and / or the other of its two main faces optically useful to satisfy the prescribed geometric model and correction. Due to the high precision and roughness requirements to which it is subjected, this surfacing operation is divided into several sub-steps associated with as many specific workstations, so that it is necessary to organize the circulation of the lens being surfaced from one station to another.
  • machining station for surfacing each face of the lens, there is a machining station providing both roughing and finishing with two separate tools and a polishing station, possibly preceded by a smoothing station. Between these stations or after them, other workstations or control of the lens are likely to intervene, for example engraving stations, shape control or cosmetics, etc.
  • lens lock Recurrent intermediate gripping and recovery part, commonly called lens lock, is particularly delicate and expensive and often induces positioning inaccuracies likely to significantly deteriorate the optical quality of the finished lens. In fact, this lens lock is subject to two cumulative and antagonistic constraints.
  • the lens made of transparent synthetic or mineral material not yet varnished, is relatively fragile and must be preserved from any marking or cracking, especially on that of its two faces which is finished, while its other face is in course of work.
  • the risk of marking is particularly pronounced with synthetic materials.
  • the lens must be positioned on each station concerned very precisely, with a known and stable spatial orientation in a specific reference system of the station concerned.
  • This constraint of geometric stability of the blocking is particularly sharp and difficult to respect with regard to the manufacture of lenses with complex surfaces such as progressive or customized lenses that do not admit symmetry of revolution. It will be understood that the surfacing of such lenses is accompanied by variations in the cutting forces according to intense gradients and thereby causes deformations with, consequently, a relative geometrical instability of the locking of the lens.
  • a blocking support is used, sometimes also called gripping block or mandrel, having on the one hand locking means for receiving and immobilizing the lens by one of its main faces and secondly means for the fixing this support on the nose of the various machine tools or measuring and control devices, so as to ensure the locking, with the possible rotational drive, of the lens on the machine or apparatus.
  • the main difficulty lies in how to block the lens on this support, because of the constraints mentioned above.
  • Such systems use a gripping block or pneumatic mandrel which, to form a sort of vacuum suction pad, has a cavity bordered by an annular seal against which the preform is placed in abutment to define with the cavity and the seal a room in which a relative vacuum is created.
  • the vacuum can be created either in a box containing, for the locking operation, the gripping block and the lens, or under the effect of a vacuum pump connected to the cavity of the block via a pneumatic valve.
  • This pneumatic blocking solution also called vacuum blocking, does not have the same economic and environmental disadvantages as the solutions of cast or glued blocks previously mentioned.
  • the implementation of this solution is indeed particularly simple and fast, both blocking and unlocking, and it does not involve any chemical consumables.
  • this type of blocking is little used in practice.
  • the solution proves particularly difficult to implement for complex surfaces (other than spherical or toric) vis-à-vis which the seal, elastically compressible, does not provide sufficiently precise and stable support.
  • the document US3794314 discloses a pneumatic blocking support of an optical lens on a machine or apparatus according to the preamble of claim 1, having on the one hand locking means for receiving and immobilizing a face of the optical lens and secondly means for fixing it to a corresponding member of the machine or apparatus, said locking means comprising a central cavity and a seal having at least one annular part against which the lens is placed in abutment in order to define with said cavity and said seal a chamber of depression , the locking means comprising stop means arranged to provide the optical lens a rigid seat after elastic deformation of the seal. But in this support, the seal is arranged to deform in flexion and thus acts in the manner of a lip seal.
  • This arrangement does not solve all the aforementioned drawbacks. It has three major drawbacks. First, it limits the contact area of the seal with the lens that abuts against the only free edge (inner edge) of the seal. This narrowness of the contact surface tends to reduce the maximum transmittable torque, so that the risk of slipping persists. Second, it does not facilitate the search for a satisfactory compromise between stiffness and coefficient of friction, because the work in bending tends to impose a high bending stiffness, while the search for a high coefficient of friction tends instead to limit the stiffness of the elastomer. The transmitted torque can therefore hardly be increased by the choice of a suitable material. Thirdly, the bending work generates a rapid wear of the elastomer, especially when it has a high stiffness.
  • the object of the present invention is to provide an improvement to the solution of the pneumatic lock which satisfies the requirements of accuracy, stability and torque transmission required.
  • the rigidity of the seat of the lens on the support provided by the abutment means which form a seat for the lens, thus ensures the stability and accuracy of the geometric positioning of the lens on its support.
  • the geometry of the lens lock is therefore not affected by the forces generated by the surfacing tools.
  • the rigid seat provided by the abutment means allows a repetitive positioning of constant geometry, or in any case determinable, of the lens in case of unlocking / re-locking.
  • this arrangement makes it possible to choose the stiffness of the seal as well and to obtain a relatively large contact area of the seal with the lens.
  • the seal immobilizes in rotation the optical lens exclusively by friction of the relevant face of said element, to the exclusion of any mechanical indexing means. Thanks to the existence of the abutment means combined with the work in compression of the seal, it is indeed possible to choose to make the seal in a relatively flexible material, having a high coefficient of friction and thus making it possible to obtain a sufficient transmitted torque without as much require too much crushing of the lens against the support. This avoids any inadvertent marking of the lens as well as the implementation of mechanical indexing means.
  • the abutment means may for example be made in the form of an annular support member or three non-aligned point support members forming a tripod.
  • a first embodiment of a support capable of blocking, by pneumatic action, an optical lens 200, in this case an ophthalmic spectacle lens, on a machine, is proposed.
  • tool or measuring device (not shown).
  • the support comprises a block 1 having a generally rotational shape about a central axis 100.
  • This block 1 consists of two main parts: a tray 2 for receiving the lens 200 to be blocked and arranged projecting from this plate means 3 for fixing the support on the nose of the machine tool or the measuring apparatus.
  • the fixing means 3 are of conventional type and are well known in themselves to those skilled in the art; It is therefore useless to detail here the constitution or the mode of action. It suffices to mention that, as illustrated by the figures, these means are in the form of a shaft 100, comprising two sections, one cylindrical adjacent to the plateau and noted 4, and the other conical noted 5 The end of the conical section 5 is provided at the end with indexing notches 6.
  • the support has on the other hand blocking means whose function is to receive and immobilize the lens 200 by its main face opposite to that to be surfaced. These locking means are arranged on an upper face 7 of the plate 3.
  • blocking means whose function is to receive and immobilize the lens 200 by its main face opposite to that to be surfaced.
  • These locking means are arranged on an upper face 7 of the plate 3.
  • the reception face 7 of the plate 2 is generally convex and in this case presents a quasi-conical shape.
  • the locking means comprise firstly a central cavity 8 and an annular seal 9.
  • the central cavity 8 is formed in recess of the receiving face 7 of the plate 2 to form a kind of crater.
  • the annular seal 9 is attached to the plate 3 and projects from the reception face 7 of this plate.
  • the seal 9 has a flattened crown shape, with a radial dimension, that is to say a width denoted I 9 in Figure 4, at least three times greater than its thickness e 9 .
  • the locking means further comprise stop means arranged to form a stable seat and accurate reception of the lens 200, as will be better explained later. More precisely, in the first example illustrated in FIGS. 1 to 5, these abutment means are in the form of an annular bead 10 of revolution about the axis 100. This annular bead is constituted by a circular ridge of 100 axis bordering the central cavity 8 and formed at the top of its side. It is preferable, in order not to mark the face 202 of the lens 200, that this ridge or bead does not have a sharp edge, but on the contrary has a second-order surface continuity.
  • the receiving face 7 On the outside of this abutment bead, the receiving face 7 has a recess 12 around which the inner edge of the seal 9 engages and which forms thus, a seat for setting the seal 9 on the axis 100.
  • the recess 12 has a depth e 12 that is substantially smaller than the thickness e 9 of the seal 9, so that the seal 9 It clearly projects from the reception face 7.
  • the seal 9 therefore protrudes from the reception face 7 by 0.7 mm.
  • Block 1 is made in one piece integrally molded from a rigid material such as metal or a rigid plastic material. Only the seal 9, for example rubber, is attached to this block.
  • the lens 200 is first resting on its concave face 202 against the seal 9 to delimit with the cavity 8 and the seal 9 a vacuum chamber 11.
  • a relative vacuum is then created in this chamber 11 to block the lens 200 by suction effect.
  • the vacuum can be created, in a manner known per se, either in a box containing, for the blocking operation, the support and the lens, or under the effect of a vacuum pump connected to the chamber 11 via an opening (not shown) provided in the block 1 and equipped with a pneumatic valve (not shown).
  • the intensity of the depression must result from a compromise between blocking strength and preservation of the optical integrity of the concave face 202 of the lens. In the tests, satisfactory results were obtained with a depression of the order of -0.9 bar.
  • seal 9 immobilizes in rotation the optical lens 200 exclusively by friction of its concave face 202, to the exclusion of any mechanical indexing means.
  • FIG. 6 there is shown a second embodiment of the invention.
  • the support proposed here comprises, as previously described with reference to FIGS. 1 to 5, a block 20 generally of revolution with a receiving plate 21 and an attachment sleeve 22 arranged along a common axis.
  • the handle 22 is identical to the handle 3 of the first embodiment.
  • the receiving tray 21 is provided, for the locking of a lens (not shown) such as the lens 200 of the first example, locking means having the function of receiving and immobilizing the lens by its face opposite to that to be surfaced. These locking means are arranged on an upper face 23 of the plate 21.
  • a lens such as the lens 200 of the first example
  • locking means having the function of receiving and immobilizing the lens by its face opposite to that to be surfaced.
  • These locking means are arranged on an upper face 23 of the plate 21.
  • the reception face 23 of the plate 21 is here generally flat or concave.
  • the locking means comprise a central cavity 24 formed in recess of the reception face 23 and an annular seal 25 attached to the plate 21 and projecting from the reception face 23 of this plate.
  • the seal 25 has a flattened crown shape, with a width much greater than its thickness, and has a conical inner flange which engages with the flank of the bowl 24.
  • the seal 25 matches the flat or concave shape of the face d 23. The latter does not present here any recess, the seal 25 is raised on this face of all its thickness.
  • the locking means further comprise stop means arranged to form a stable seat and accurate reception of the lens.
  • abutment means are here in the form of three non-aligned projecting studs 26 forming a tripod. These three studs 26 are arranged equidistantly on a circle of the same axis as the block 20 adjacent to the outer edge of the seal 25, which comes into wedging against these pads.
  • Each of the three studs 26 is conically shaped and has a vertex which, in order not to mark the lens, is blunted.
  • the vertices of the three studs 26 are inscribed in a plane perpendicular to the axis of the handle 22 of the block 20.
  • FIG. 7 illustrates a third example of execution of a support according to the invention.
  • the support proposed here comprises, as before, a block 30 generally of revolution with a receiving plate 31 and a fixing sleeve 32 arranged along a common axis.
  • the handle 32 is identical to the handle 3 of the first embodiment.
  • the receiving plate 31 is provided, for the locking of a lens (not shown) such as the lens 200 of the first example, locking means having the function of receiving and immobilizing the lens by its face opposite to the one to be surfaced.

  • the locking means comprise a central cavity 34 formed in recess of the receiving face 33 and an annular seal 35 attached to the plate 31 and completely covering the receiving face 33 of this plate.
  • the seal 35 has a raised washer shape, reminiscent of that of a container or cap, with a plurality of concentric annular portions.
  • annular portions there are thus, in this case, four annular portions, among which: an outer annular portion 36 generally conical, matching the reception face 33, an intermediate annular portion 37 which is also conical with a reduced apex angle with respect to the outer portion 36, a conical inner collar 38, of even smaller angle, which engages with the side of the bowl 34, and a central pellet 34 resting against the bottom of the bowl 34.
  • the bottom and the side of the bowl 34 are thus completely covered by the seal 35.
  • the locking means further comprise stop means arranged to form a stable and accurate seat for receiving the lens.
  • stop means are presented here, as in the second example, in the form of three non-aligned projecting studs 40 forming a tripod.
  • These three studs 40 are arranged equidistantly on a circle of the same axis as the block 30 located at the right of the intermediate annular portion 37 of the seal 35. This intermediate portion then has three days for the passage of the three studs 40, which thus project seal 35 through its intermediate portion 37.
  • Each of the three studs 40 is of conical shape and has a vertex which, to avoid marking the lens, is blunted.
  • the vertices of the three studs 40 are inscribed in a plane perpendicular to the axis of the handle 32 of the block 30.
