Definitions
- the present invention relates to the drilling of optical glasses for the production of so-called glasses with pierced glasses and without surrounding frame.
- BACKGROUND OF THE INVENTION There have been structures of wire frames for a long time on which the spectacle lenses have been fixed by bolting or other systems, the lenses then being not surrounded by the frame. Each spectacle lens then has one or more holes and / or a through notch at the level of the nasal zone and the temporal zone of said lens.
- various mechanical fixing means have been proposed, the most common of which are bolting.
- Document JP-A-8 155 945 describes a unit for drilling optical glasses making it possible to make two through holes in the vicinity of opposite edges of each spectacle lens. This document describes a machining assembly with a very complex structure and a high cost. Document JP-A-8 155 806 also describes a drilling assembly with oscillating glass supports. For the drilling of particular holes in optical glasses, reference may also be made to documents WO-A-00/68 729 describing a drilling assembly intended to make oblong through holes, and to document OA-99/37 449 describing a set of drilling adapted to the machining of blind holes made in the thickness of the glass.
- Each support is mounted to slide in horizontal translation, which makes it possible to carry out, by two successive machining operations, a hole and a notch, or two holes, along a rectilinear path.
- the identification of the machining points is always carried out from an indexing calibrated on the center of the glass, said center being considered as a zero point of coordinate system forming the center of two coordinate axes in a horizontal plane.
- the machine is calibrated, so that any new movement in XY makes it possible to exactly position the tool for drilling at a given point in the glass .
- the aim of the present invention is to devise a technique for piercing optical glasses which does not have the aforementioned drawbacks and limitations, while calling upon a drill with digital control.
- the object of the invention is therefore to design a drilling method and a device for implementing said method which are both simple and easy to implement, while guaranteeing optimum precision in the production of the desired holes or notches, and this without being in any way limited to a particular form of glasses.
- a method of piercing optical glasses for the production of glasses called pierced glasses and without surrounding frame by means of a numerically controlled drill having a support of tool displaceable in translation in three directions of coordinates X, Y, Z, the associated drilling tool being driven in rotation and displaceable in translation along its axis which is parallel to one of said directions, comprising the successive steps following: a) a glass is positioned, by moving it in a plane substantially perpendicular to the axis of the drilling tool, with respect to a reference needle, whose position in said plane is known to the corn drill - digital command, until bringing a previously marked reference point on an edge of the glass bearing against the reference needle, after which said glass is immobilized in this position; b) the drilling tool is then brought closer to the glass still immobilized, and the reference needle is retracted to release the support zone from the glass; c) the drilling tool is controlled to carry out pre
- the zero point of the machining sequences is constituted for the drill with numerical control by a reference point of the edge of the glass. It is easy to understand that the prior marking of such a reference point on an edge of the glass is completely independent of the profile of said glass, in particular of the shape of its outline which can adopt all imaginable shapes of fantasy going well beyond the geometrical shapes usually used for spectacle lenses. We have therefore managed to abandon the tracking with respect to a glass center, which makes it possible to carry out machining of glasses of any shape without having to memorize all the shapes concerned beforehand. The only memorization then concerns the types of machining sequences to be carried out with the drill with digital control, according to the mode of connection between the lenses and the frame concerned.
- the right and left lenses of the glasses to be produced are positioned side by side, each lens having a reference point which is brought into abutment against an associated reference needle, after which each lens is immobilized in its respective position, each marker needle is then retracted during step b) for the prepro- respective grammages.
- the marker needles are part of the same retractable piece on either side from which the right and left glasses are brought in order to perform symmetrically the piercings of the nasal zone or of the temporal zone of the two glasses. .
- step a) the positions are replaced in a new step a) in order to then carry out the sequences relating to the other zone.
- step a) the or each glass is moved then immobilized on a plane slightly inclined laterally so that the drilling tool approaches the glass concerned perpendicular to the concerned face of said glass. Provision may also be made for two juxtaposed inclined planes, the inclination of which is adjusted symmetrically for the right lens and the left lens.
- the retraction of the marker needle (s) is carried out automatically or manually, in a direction parallel to the vertical direction Z.
- the se - Machining quences are taken from a memory into which a plurality of sequences have entered, each comprising a plurality of notches and / or holes, through or not, arranged according to a predetermined pattern.
- the invention also relates to a device for implementing a drilling method having at least one of the preceding characteristics, said device being remarkable in that it comprises: - an essentially horizontal plate carrying a drill with digital control having an overhanging tool support movable in translation in three directions of coordinates X, Y, Z and the drilling tool of which is driven in rotation and displaceable in translation along its axis which remains essentially vertical; - a marker needle mounted on the plate, being movable between an active glass support position and a retracted position released from the glass; and a glass support arranged to hold a glass in an essentially horizontal plane, said support resting on a plane integral with the above-mentioned plate and being immobilizable in position relative to said plane.
- the marker needle comprises a vertical baluster fixed on the plate, and a mobile slider on said baluster between a high active position and a low retracted position, said slider having at least one lateral edge serving to support the edge of the glass. concerned at a reference point thereof.
- the slide of the marker needle has a lateral support edge on each side of the axis of the support column, and two glass supports are provided in order to place the right and left glasses one next to the other. the other.
- the lateral support edge provided on one or on each side of the slide is a rib extending vertically.
- the plate is surmounted by two support plates forming a dihedral, and whose inclination upwards or downwards is symmetrically adjustable by an associated common adjustment means. This makes it possible for the drilling tool to land on the glass perpendicular to the face concerned of said glass.
- the glass support comprises a disengageable magnetic locking block, immobilizable in any position on the plane or the inclined plates surmounting the plate, the upper face of which is made of ferro-magnetic material, said block being surmounted by a means for holding a glass in a substantially horizontal plane.
- the glass support is subject to the plate to move in two orthogonal directions corresponding to the directions of coordinates X, Y.
- FIG. 1 is a perspective view showing a drilling assembly of optical glasses according to the invention, implementing the drilling method of the invention
- - Figure 2 is a partial view on an enlarged scale, illustrating in perspective a glass support fitted to the device of Figure 1, here of the disengageable magnetic locking type, with the associated guide means in X, Y
- - Figure 3 is a schematic top view illustrating the successive steps of the drilling method according to the invention implemented on a single glass
- - Figure 4 is a schematic top view similar to that of Figure 3, illustrating a setting work of the process of the invention on the right lens and the left lens of the spectacles to be produced
- - Figures 5A and 5B are two elevational views illustrating the placement of the glasses on planes slightly inclined laterally, so that the drilling tool approaches the glass perpendicular to the respective convex or concave face concerned.
- FIG. 1 there is distinguished an assembly for drilling optical glasses denoted 10.
- the assembly 10 comprises a plate 11 essentially horizontal, carrying a drill with digital control 12.
- the digital drill 12 here comprises sub-assemblies 13.1, 13.2, 13.3, the latter including an electric drive motor not visible here, motor whose output shaft is coupled to a mandrel 14 used for fixing a drilling tool 15 such than a strawberry.
- the drilling tool is rotated about its axis 16 by the associated motorized means.
- the digitally controlled drill 12 comprises a lower block 13.1 which is mounted on the plate 11 so as to be able to move in two directions of coordinates X, Y, which block is surmounted by a tool support 13.3 mounted on a mobile vertical column 13.2.
- the tool support 13.3 is thus movable in a controlled manner in a direction of essentially vertical Z coordinate, in addition to the directions of coordinates X, Y due to its mounting on the block 13.1.
- the drilling tool 15 can be moved both in the directions X, Y of a horizontal plane, and in the direction of its axis in the direction of the Z coordinate, as shown schematically by the double arrow 100.
- the drill tool 15 is a cutter pe ⁇ tit diameter, for example of the order of 1 mm, in preference to a drill, to make holes larger diameter by milling without changing the tool, and more generally to realize any form of drilling or milling, through or not.
- the movement control of the drilling tool 15 can be carried out directly on the apparatus by means of adjustment buttons and associated switches provided on the front face of the plate 11, these buttons and switches being referenced 17.1, 17.2, 17.3, 17.4, 17.5 and 17.6.
- a PC computer 18 associated with a keyboard 19, the assembly being connected by a cable 18.1 to the digital drill 12. This assembly of computer is therefore capable of sending movement instructions to make carry out a predetermined trajectory by the drilling tool 15.
- the drilling assembly 10 also comprises a horizontal plate 20 mounted on the plate 11, said plate forming a support plane and being in this case constituted by a unitary plate of ferro-magnetic material.
- a glass support denoted 50 arranged to hold a glass V in an essentially horizontal plane, said support resting on the plate 20 being immobilizable in position relative to said plate.
- FIG. 1 We also distinguish in Figure 1 certain equipment associated with the glass support 50, which is here produced in the form of a block 51 with disengageable magnetic locking, immobilizable in any position on the plate 20.
- a button 53 used to control the immobilization in position of support block 51, and a holding means 55 serving to ensure the positioning of the glass to be machined.
- the arrangement of the support block 51 will be better understood by referring to the description part given below with reference to FIG. 2.
- a further distinction is made between the presence, on the plate 20, of two C-shaped slides 25 , facing one another and each including a rack 26.
- each meshing with a respective rack serves to ensure the positioning X, Y of the support block 51 by virtue of an overlapping profile 52 passing without play on the crossbar 27.
- the displacements in X, Y of the support block 51 are here shown diagrammatically by double arrows 102 and 101 respectively.
- FIG. 1 also allows to distinguish another means whose function is essential in the context of the present invention. It is in fact a marker pointer generally constituted by an assembly 30, and whose position in the plane X, Y is known to the digitally controlled drill 12.
- the marker needle 30 comprises here a vertical column 31 fixed on the plate 11 (in this case directly on the plate 20), and a slide 32 movable vertically on said column, said slide having at least one lateral edge 33 constituted by a tapered rib extending vertically.
- a lateral edge 33 is provided on each side of the slide 32, this rib preferably being made of rigid plastic material, such as nylon or the like, to be both precise and not to risk splinters. or more generally to damage the edge of the glass which is brought to bear against said rib, in accordance with the procedure which will be described below in more detail.
- the assembly forming a marker needle 30 thus comprises a column of vertical axis 31, here of rectangular section, on which a slide 32 can move, projecting laterally, on each side of the axis of the column, a tapered vertical rib 33.
- This marker needle is mounted on the baluster 31 while being movable between a high position (illustrated in solid line) which corresponds to an active position of glass support, as illustrated in FIG. 2, and a low retracted position (as shown schematically by a portion of rib illustrated in phantom in Figure 2) which is released from the glass.
- Maintaining the high position of the slide 32 on its vertical column can be ensured by mechanical or electromagnetic means, which have not been shown here. It could for example be an erasable snap-on ball, or a magnet, or any other equivalent means.
- the passage from the high position to the low position of the slide 32 may also be carried out by mechanical, electrical, or electromagnetic means, linked to the descent of the drilling tool, or alternatively manually by acting directly on the slide to push it onto its baluster.
- a simple way to achieve automatic control of the downward movement of the slider 32 is to provide a vertical rod (not shown here) fixed on the tool support 13.3 and which comes to bear on the slider 32 at the lowering of the drilling tool, so that the marking needle is automatically retracted when the drilling tool arrives in a Work zone.
- any system based on cable or electromagnet can be used to control the automatic descent of the slide down.
- the reference needle illustrated here has two lateral support edges 33, on either side of the axis of the baluster, which makes it possible to support two glasses to be machined, on the share and on the other side of the marker needle.
- Figure 2 further illustrates in more detail the glass support 50, which is arranged to hold a glass V in an essentially horizontal plane. The glass support 50 is therefore produced in the form of a block
- a control button 53 can rotate, as shown schematically by the double arrow 105, between two positions corresponding respectively to the immobilization in position of the block 51 on the upper face of the plate 20, or to the release of the magnetic lock to allow the free sliding block 51 on the upper face of the plate 20.
- the displacement in a direction parallel to that of the racks 25 corresponds to a displacement in Y diagrammed by the double arrow 101
- the transverse displacement, along the axis of the bar 27, corresponds to a displacement in X diagrammed by the double arrow 102.
- the support 50 is thus secured to the plate 20 to move in two orthogonal directions 101, 102 forming a system of coordinates in X, Y.
- the block 51 with magnetic locking is also surmounted by a means 55 for holding a glass V in a substantially horizontal plane.
- This holding means 55 can in practice be produced in different ways, and a bracket 54 is illustrated here rigidly secured to the block 51, said bracket supporting a movable assembly forming a collet.
- This movable assembly comprises an operating element 60 constituted by a wheel 61 coupled in rotation to a rod 62 whose lower part 63 is threaded, so that the rotation in one direction or the other, as shown schematically by the double arrow 106 , allows to raise or lower a terminal holding buffer 59.
- the glass V rests on a fixed part constituted by a support 56 secured to the block 51, which support is here surmounted by a flexible assembly 57 ending in an O-ring washer 58.
- the flexible means 58, 59 used to tighten the glass it is possible to use the superimposed support ending in a clamping pad mounted on a ball joint, therefore making it possible to adapt naturally to the different curvatures of the internal and / or external faces.
- glasses to be tightened each shoe preferably being equipped with an O-ring washer ensuring contact with the glass without risk of scratching the surface thereof.
- one or other of the parts which comes into contact with the glass may include a suction cup accessory (not shown here) making it possible to receive, for example by interlocking, different models of suction cups used on glass grinders optics, and also a simple piece with an O-ring to tighten glasses not fitted with suction cups.
- a first step can be distinguished, denoted a1), during which an optical glass V is placed, on one edge of which has been marked a particular point denoted PR which is a reference point for the machining sequences which must be performed later on the glass.
- PR a particular point for the machining sequences which must be performed later on the glass.
- the glass V is of course fixed on its magnetic type support not shown here.
- the support is movable by sliding support on the plate 20 in X, Y, which allows the glass V to be gradually displaced until the reference point PR is brought exactly to the point of the rib forming the marker needle 33, as illustrated in a2).
- the glass V is positioned by moving it in a plane substantially perpendicular to the axis 16 of the drilling tool, with respect to the marker needle 33 whose position in said plane is known to the drill. digitally controlled 12, until bringing the reference point PR, previously marked on the edge of the glass V, in abutment against the marker needle 30, 33, after which said glass is immobilized in this position.
- the immobilization is carried out very simply, by turning the control button 53 of the magnetic support 50.
- step b) the drilling tool 15 (not shown) is then brought closer to the glass V still immobilized, and the marker needle 30, 33 is retracted to clear the support area of the glass as is shown schematically by the representation in dashed lines of said marker needle.
- the drilling tool 15 can then carry out any desired trajectory previously established relative to the glass whose position is known by the reference point PR.
- step c) the drilling tool 15 is controlled to carry out pre-programmed machining sequences, using the position of the reference point. rence PR of glass V as zero point of said sequences.
- the machining sequences are preferably taken from a memory into which a plurality of sequences have entered, each comprising a plurality of notches and / or holes, through or not, arranged according to a predetermined pattern. These sequences will in this case relate to the nasal zone ZN of the lens concerned V.
- pattern Ml a through hole PI and a through notch El
- pattern M2 two through holes P2.1, P2.2 which are substantially superimposed
- pattern M3 two through holes P3.1, P3.2 substantially aligned horizontally
- motif M4 an elongated through hole L4 in a substantially vertical direction
- motif M5 a through hole P5 and a non-opening notch E5
- motif M6 surface machining without opening P6 in accordance with a motif for technical and / or aesthetic purposes.
- the drilling tool 15 is controlled to carry out preprogrammed machining sequences, using the position of the reference point PR of the glass V as the zero point of said sequences.
- step a ' the glass support V has been moved again in the plane X, Y until bringing another reference point PR' previously marked on the edge opposite of glass V resting against the marker needle 30, 33, after which the glass is again immobilized in this position.
- FIG. 4 We will now illustrate an advantageous variant of the method described above, which makes it possible to work directly on the right lens and the left lens of the spectacles to be produced, with reference to FIG. 4.
- the marker needle 30 in this case imperatively comprises two projecting support ribs 33, on either side the axis of the fixed baluster 31. Each support will then be moved until bringing the reference point PR of each glass VD or VG against a lateral support edge 33, as illustrated in a2).
- step a ′ This is illustrated in step a ') where it can be seen that the right and left glasses have been replaced.
- step a ′ the process resumes as before, with retraction of the double marker needle, and control of the preprogrammed machining sequences for each of the glasses, in the time zone thereof.
- the procedure which has just been described is perfectly suitable for the machining of corrective or non-corrective lenses, of all forms of contours, and of all thicknesses or materials.
- FIGS. 5A and 5B The device of the invention has been designed for this purpose, and we will refer to this in FIGS. 5A and 5B.
- the main modification resides in the presence of one or two (here two) support plates 41 whose inclination is adjustable. Indeed, by tilting laterally the bearing surface on which the glass support 50 rests, one can modify the inclination of the glass fixed on said support, so that the face to be machined locally has a substantially horizontal tangent plane.
- two support plates 41 are provided, articulated at the level of a central pivot 42 extending in the direction Y, and thus forming a dihedral.
- the inclination of the two support plates 41 upwards or downwards is symmetrically adjustable by an associated common adjustment means 45, here constituted by an assembly of superimposed washers 46 and an operating wheel 47 allowing, by rotation of the latter around a vertical axis, to modify the inclination of the support plates 41, while retaining the symmetry with respect to a median vertical plane.

- FIG. 5B the central parts of the plates support 41 have been lowered, with a view to a perpendicular attack on the concave face of the two glasses by the drilling tool 15.
- the screen systematically presents an icon of the machining pattern selected, to avoid any error in the machining of the glasses.
- the machining patterns are to be memorized, it being understood once again that the drilling method according to the invention is in no way dependent on the shape of the contour of the glass.
