Definitions
- a mount usually has circles, or surrounds, having an inner bezel forming a groove.
- the trimming of a lens for mounting in the frame chosen by the future carrier then consists in modifying the contour of the lens to adapt it to this frame.
- the clipping of the lens has a finishing step called beveling which consists in ensuring the formation of a nesting rib on the edge of the ophthalmic lens.
- This nesting rib is usually called bevel, because it has in general (but not necessarily) the shape of a profile of triangular cross section.
- This bevel is intended to be engaged in a peripheral inner groove, called bezel, formed in the frame of the frame.
- each of its circles most often has an open junction portion which, when mounted, is closed around the lens using a barrel.
- This barrel comprises an upper portion and a lower portion which are arranged on either side of the junction portion of the contour of the circle and which are secured to one another by means of a screw.
- the mounting circle has a discontinuity and, therefore, the bevel does not fit properly into the portion of the bezel of the circle corresponding to the connecting portion of the barrel. to the circle of the mount.
- This portion of the bevel that does not fit into the portion corresponding to the bezel of the circle forms an obstacle to the interlocking of the lens in the circle.

- the control means are programmed to control the clipping means and / or the support means so that the nesting rib formed is narrowed in width and / or height locally on the recorded singular portion of the desired contour.
- the localized narrowing of all or part of the singular portions of the interlocking rib of the lens makes it possible to eliminate the parts of the interlocking rib which obstruct its proper interlocking in the bezel of the hoop of the frame.
- the resulting nesting rib on the edge of the lens can then be properly nested in the bezel of the frame of the frame without undergoing excessive stress.
- the mounting of the lens in the frame of the frame is then reliable and more accurate.
- the determination means are designed to determine and memorize said singular portion of the desired contour of the lens prior to the formation of the engagement rib of the lens. It is therefore not a matter of determining a portion to be retouched on the basis of a bad fit in the bezel of the frame or an unsatisfactory machining, but of the predictive determination, that is to say to a priori, a clipping setpoint for the formation of a direct fitting rib satisfactory from the first machining without any recovery.
- the determination means are able to determine:
- the interlocking rib having a width in the direction of the axis of the lens, the narrowing of the interlocking rib comprises a reduction in the width of the interlocking rib.
- the cutting means comprising a machining tool for forming the interlocking rib, reducing the width of the interlocking rib is achieved by moving the tool in a direction substantially parallel to the axis of the lens, offset transversely to the longitudinal direction of the interlocking rib.
- the machining tool having a groove for forming the interlocking rib, the movement of the tool is made in one direction and then in the opposite direction in transverse offset with respect to the longitudinal direction of the interlocking rib, so that to narrow the width of the interlocking rib.
- control means are programmed to control the shaping means and / or the support means so that the narrowing of the engagement rib is made simultaneously with the formation of the nesting rib.
- control means are programmed to control the shaping means and / or the support means so that the engagement rib is made in two stages with a first rib formation step. uniformly nesting and a local narrowing step of this nesting rib on the particular singular portion.
- the step of shrinking is carried out by means of a grinding, milling or cutting tool with a diameter of less than 40 mm.
- the narrowing can thus be achieved accurately and over a small area.
- the determination means are designed to:
- the determination means are designed to:
- the identification of the singular point of the circle of the frame is performed automatically by image processing and by means of a search algorithm of the singular point as point of attachment of the circle of the mount to the branches and the nasal bridge of the mount.
- the determination means are designed to:
- the identification of the singular point of the desired contour of the lens is performed automatically by means of a point search algorithm. singular as a point of discontinuity of first or second order on the desired contour of the lens.

- This singular portion 314 of the desired contour 112 of the lens 400 corresponds to the singular portion 304 of junction between the circle 12 and the barrel 324 of the frame 10.
- the determination device 199 comprises a man-machine interface 110.
- This man-machine interface 110 is provided with a touch screen 100 and selection buttons 102, 103 which are in the form of icon allowing the operator to interact with the method of determining the singular portion described below.
- the selection button 102 has a barrel icon.
- the pressure of this selection button 102 informs the computer and electronic processing unit 198 that the singular portion 301, 304 relative to the barrel 321, 324 will be defined on the touch screen 100 by the operator.
- the electronic and computer processing unit 198 then stores, in a memory field associated with the singular portion relative to the barrel, the point or the portion of the screen that is pointed by the operator as explained below.
- the selection button 103 has a wafer icon.
- the pressure of this selection button 102 informs the electronic and computer processing unit 198 that the singular portion 302, 303 relative to the junction portion of the bridge, close to one of the platelets, will be defined on the 100 touch screen by the operator.
- the electronic and computer processing unit 198 then provides for storing in a memory field, associated with the singular portion relating to the nasal bridge, the point or portion of the screen that is pointed by the operator as explained further.
- This trimming device 6 comprises a train of several grinding wheels 614 mounted coaxially on an axis A3, for roughing and finish of the edging of the ophthalmic lens 400 to be machined.
- the grinding wheel 614 is attached to a common shaft of axis A3 ensuring their driving in rotation during the edging operation.
- the wheel train 614 is also movable in translation along the axis A3. This translation movement is called “transfer” and is denoted TRA in FIG.
- the trimming device 6 also comprises two clamping shafts 612, 613 which are aligned with each other along an axis A2, called a locking pin which is parallel to the axis A3 of the gear train. millstones.
- the restitution movements RES, of the transfer transfer TRA of the wheel set 614 and the rotational movement ROT of the shafts 612, 613 for supporting the lens 400 are controlled in coordination by the electronic and computer processing unit 600, duly programmed for this purpose, so that all the points of the edge 409 of the lens 400 are successively brought back to the right radius.
- the operator selects the numerical models 111, 112 of the circles 11, 12 of the frame 10 chosen by the operator.
- the numerical models 111, 112 of the circles 11, 12 of the frame 10 constitute the desired contours 111, 112 of the lens 400 to be trimmed.
- the desired contours 111, 112 are then displayed on the touchscreen scale 1.
- the desired contours 111, 112 displayed are arranged along the horizontal axis H.
- the singular portion 314 of the desired contour 112 of the lens 400 is determined as a portion of that contour adjacent to or encompassing said singular point 204. As shown in FIG. 204, stored by the electronic and computer processing unit 198, the parameters of the corresponding singular portion 314 of the desired contour 112 of the circle 12. In fact, each singular portion of the desired contour corresponding to the singular portion 301, 302, 303, 304 of one of the circles 11, 12 of the frame is stored by the electronic and computer processing unit by a pair of values which has an angle value ALPHA and a length value D_ALPHA.
- the angle value ALPHA is the value of the angle formed between the horizontal axis H and a straight line passing through the center CB of the desired contour 112 and the central point 214 of the singular portion 314 determined.
- the central point 214 of the singular portion 314 is determined from the point 204 defined by the operator on the touch screen, as being the radial projection of the point 204 on the desired contour 112. It can also be considered for simplicity that the point central 214 of the singular portion 314 substantially corresponds to the point 204 defined by the operator.
- the center of the contour of the circle can be defined as the boxing center, well known to those skilled in the art, which is the point of intersection of the diagonals of the horizontal rectangle in which is inscribed the shape of the desired contour of the lens in the port configuration (defining the horizontality). As a variant, it is possible to choose another reference point for calculating the angle value ALPHA.
- the length value D_ALPHA is the length of the arc over which the singular portion 314 of the desired contour 112 extends.
- This length value D_ALPHA can be set by default or as a percentage of the perimeter of the desired contour 112. It can also be provide that this value of length D_ALPHA is provided by default but depends on the type of singular portion, that is to say according to whether the singular portion is associated with the barrel or nasal bridge. Finally, it can be provided that this length D_ALPHA is not defined by default and that the operator makes the pen scroll on the touch screen 100 the desired length of the singular portion which is then stored as the length D-ALPHA this singular portion.
- the pair of values D_ALPHA, ALPHA thus makes it possible to identify, on the one hand, the angular position of each singular portion 314 on each desired contour 111, 112 of the lens 400 and, on the other hand, the length of the bevel 410 to shrink around this angular position.
- a singular portion 404 of the edge of the lens 400 to be trimmed whose position parameters in the H mark, V are the angle values ALPHA and length D_ALPHA. The lens is then trimmed as follows.
- the uncut lens 400 is placed in the trimming device 6.
- the shaft 613 is displaced in translation along the blocking axis A2, facing the other shaft 612, in order to clamp in axial compression of the lens 400 between the two locking noses.
- the electronic and computer processing unit 198 of the determination device is connected with the electronic and computer processing unit 600 of the trimming device 6 and communicates to the latter the angle parameters ALPHA and length D_ALPHA of the singular portions 404. of the singing of the lens 400 to be cut out.
- the two electronic and computer processing units 600, 198 are provided with communication means by a network architecture.
- a step is performed for roughing the edge 409 of the lens on the cylindrical blank wheel 50 present on the grinding wheel 416.
- the lens is trimmed so as to approach the shape that one wishes to give to the lens.
- the finishing step is carried out.
- the desired shape of the periphery of the lens is reached precisely and the bevel 410 is formed by the beveling groove 57 which impregnates its shape on the edge 409 of the lens.
- the bevel 410 then comprises two inclined flanks 411, 412.
- the narrowing of the engagement rib 410 is performed simultaneously with the formation of this nesting rib 410.
- the electronic processing unit and computer 600 pilot the R2007 / 001,534
- the singular portion 404 corresponds to the singular portion 314 determined on the desired contour 112 from the singular portion 304 of the circle 12 of the frame 10.
- the steering of the displacement is achieved by moving the beveling wheel 50 according to its transverse displacement mobility TRA to reduce the width of the bevel along the length of the singular portion 404 of the lens corresponding to the singular portion 314 determined on the desired contour of the lens. This also results in a decrease in height of the bevel.
- the steering of the displacement comprises a displacement of the finishing wheel 55 in a given direction along the axis A2 of the lens then in the opposite direction so as to narrow the two flanks 411, 412 of the bevel 410.
- the portion singular 404 of the bevel 410 can thus be narrowed more precisely by limiting the risk of discontinuity of the singular portion narrowed with the remainder of the bevel 410.
- this control of the movement of the beveling wheel makes it possible to keep the average position of the bevel 410 on the edge 409 of the lens 400.
- the narrowing of the bevel can be performed after the formation of the bevel 410 on the edge 409 of the lens 400.
- the first beveling pass is then made to form a bevel 410 whose width is that of the beveling groove 57, on the whole contour of the fast lens.
- a second pass is made with the beveling wheel 57 to precisely narrow the bevel according to the particular singular portions.
- the machining of the singular portion during the second pass is made with another grinding wheel having a smaller opening bevel groove, which makes it possible to dispense with a piloting of the transverse displacement of the finishing wheel to reduce the bevel already made.
- the step of shrinking is performed by means of a grinding tool, milling or cutting of reduced diameter, less than that of the large grinding wheel 55 (whose diameter is about 150 mm ). It is thus advantageously possible to use a tool with a reduced diameter of less than 40 mm. As illustrated in FIG. 6, a cut-off lens 400 is thus obtained, which presents on the singular portion 404 of the contour of the lens a cross-section of its reduced bevel.
- a second embodiment (not shown) of the determination of the singular portion of one of the desired contours.
- the elements of the first embodiment are repeated except the use of a stylus by the operator.
- a digital cursor is virtually attached to the desired digital outline that is displayed on the screen.
- a touch of the electronic processing unit and computer makes it possible to scroll to this cursor, by pressing this key, the perimeter of the desired contour displayed.
- the cursor attached to the desired contour is scrolled until it reaches the center of the singular portion of the circle of the mount. Since the mount, and in particular the singular portion of this frame, masks the corresponding portion of the desired contour, it can be provided that the cursor attached to the desired contour is of sufficient size to be marked when the desired contour is masked by the corresponding circle of Frame.
- the cursor is thus designed to extend over a sufficient area to not be hidden by the frame superimposed on the desired contour.
- the cursor may take the form of a square or a cross for example.
- a mouse with a pointer of shape and size adapted to be positioned and marked on the singular portion of the desired contour.
- a third embodiment (not shown) which incorporates the elements of the first embodiment, but according to which the frame is no longer physically superimposed on the desired contours of the circles displayed on the screen.
- the shape of the frame is digitized and stored in the determination device 6, by example by means of a digital image capture device associated with an image processing algorithm implemented on the electronic processing unit and computer 198 of the determination device for detecting and digitizing the outline of the frame.
- the digital image capture device may for example consist of a Kappa CTD® telescope lens centering device marketed since May 2004 by the Applicant.
- the digitized image of the circles of the frame is then superimposed on the computer to the desired contour of each lens, which as recalled above was obtained from a mount circle bezel reading device or a computer file provided. by the manufacturer of the frame.
- the operator points with a graphical pointer integrated in the user interface, for example a stylus, the center of the singular portion of the circle of the mount numerically superimposed on the desired contour.
- the length D_ALPHA of the singular portion of the desired contour can then be defined by default.
- the operator can also scroll with the stylet the length he wants to define the length D_ALPHA of the singular portion of the desired contour.
- the identification of the center of the singular portion, or singular point, of the circle of the frame can be carried out by image processing.
- the circles of the frame being digitally superimposed on the desired contours and the singular portions of the circles of the frame being identified, the electronic and computer processing unit stores, as described in the first embodiment, the corresponding pair of values ALPHA, D_ALPHA. to the singular portion of the desired contour.
- the determination device is designed to:
- the display screen of the desired contour and the representation of the circle are omitted.
- the superposition of the contour and the representation of the circle is then performed virtually by calculation.
- the identification of the singular point (s) is therefore performed by image processing.
- the determination, automatically by image processing, of the singular point of the rim of the frame is carried out by means of a search algorithm of the singular point as a point of attachment from the circle of the mount to the branches and the nasal bridge of the mount.
- the determination device is designed to:
- the physical frame or the memorization of the representation of the circle of the frame is dispensed with.
- the identification of the singular point is then performed not by image processing or by pointing, but by calculation from the digital data of the desired contour of the lens.
- the identification of the singular point of the desired contour of the lens is performed automatically by means of a singular point search algorithm as a first or second order discontinuity point on the desired lens contour.
- the algorithm may in particular search for a first order discontinuity point on the desired lens contour.
- the algorithm is designed to find the point of discontinuity exclusively in the nasal and / or temporal areas of the desired contour of the lens.
- the present invention is not limited to the embodiments described and shown, but the skilled person will be able to make any variant within his mind.
