Definitions
- the invention relates to a device for processing a bilaterally optically active lens with a cutting, milling and / or a polishing unit for machining at least a first side of the lens and a method for machining a bilaterally optically active lens with a cutting, Milling and / or a polishing unit for processing at least a first side of the lens, the lens being held by a first holding device assigned to a second side.
- a lens blank made of plastic or glass is used, one or first side of which already shows the final optically effective shape.
- Such lens blanks are stored in increments with regard to the radii of curvature of the spherical surface.
- the lens blank is blocked, that is to say it is fastened with the front surface or first side to a block piece which is clamped into the chuck of a lens grinding machine.
- the front or first side is usually provided with an individual varifocal surface by means of a cutting process.
- a progressive surface is understood to mean a surface that deviates in parts from a symmetrical - generally spherical - base surface, so that a progressive lens with near and far vision areas and the corresponding transition areas is created.
- the base surface of the front surface or first side is tilted, offset and / or phase-shifted relative to the rear surface or second side.
- the lens blank has previously been attached to a block by means of a metallic paste with the rear surface.
- the lens blocked in this way is clamped into the head of a workpiece spindle for processing. Since the lens blank is attached directly to the block piece, the tilt, the offset and / or the phase position during the blocking must be taken into account by attaching the lens blank to the block piece at an incline or offset. Blocking takes a long time. A separate machine is also required for this. Despite all care, this additional step results in certain, unavoidable inaccuracies.
- a machine for producing lenses is already known from EP 0 849 038 A3.
- the machine has a cutting unit and a polishing unit for processing one side of a lens.
- a Complete machining of the lens on both sides is not intended.
- a method is known from US Pat. No. 5,205,076, in which a jacket surface is also worked out when machining the first side of the lens blank for a plastic contact lens, but no contact surface for clamping the turned lens blank.
- the axis of the lateral surface coincides with the workpiece spindle axis, so that when the lens blank is received in a holding device for machining the second side, the lens blank is not tilted, so that the method is not suitable for producing lenses in a simple manner in which the optical axes on both sides do not coincide.
- the invention is based on the object of designing and designing a device and a method in such a way that complete processing of the lens is ensured on both sides.
- a reclamping unit is provided for reclamping the lens from the first side to the second side for the purpose of processing the second side of the lens. This ensures that the lens is picked up or clamped on this side after the processing of the first side, the unprocessed second side being separated from a recording adapter and then processed.
- the processing of the first side by means of a mounting adapter has the advantage that, regardless of the shape of the first surface to be produced, there is optimal space available for processing.
- the lens can be used Machining can also be clamped directly over their cylindrical basic shape.
- the transformer unit has a second holding device for the lens and the lens can be supported relative to the second holding device via at least one positioning feature, the positioning feature having a reference to the first and / or to the second side of the lens for its alignment ,
- the reference between the positioning feature and the first side serves to align the lens in the second holding device with respect to an optical axis of the first side.
- the positioning feature is generated in the same setup while processing the first page.
- the first side or the first holding surface or the support part, which is used to process the first side can also be used as a positioning feature.
- the relationship between this first holding surface or the support part to the first side is given.
- the relationship between the first page and the second page is there anyway.
- the support member is then removed by the second holding device after tensioning.
- a robot arm can also be used as the second holding device or for reclamping.
- the position feature is designed as a reference surface, the reference surface being aligned with respect to an optical axis of the first side and / or the second side.
- the reference surface is a part of the edge of the lens that remains after processing the first side of the lens. With or after editing the second page, this reference surface is removed.
- the second reference surface can be designed as a side or lateral surface of the lens and is arranged perpendicular to the reference surface, that is to say essentially parallel to the optical axis of the first side and / or the second side.
- the reference surface designed as a side surface ideally represents the later outer surface of the lens for a frame, i. h
- the lens does not have to go through any subsequent edge processing.
- the first holding surface or the supporting part, which is used for machining the first side, or the axis position of the robot, which fixes the lens position, can also be used as a positioning feature.
- the second holding device has at least two holding parts, each with at least one system assigned to at least one reference surface.
- the uniform design of the system and the holding part ensures precise positioning of the lens without additional reference between the system and the holding part.
- the contact of the lens holder is designed as a counter surface to the ring surface or reference surface of the lens blank and extends perpendicular to the workpiece spindle axis.
- a support part which can be brought into contact with the first side of the lens, the support part having a plastically and / or elastically deformable surface which can be applied to the first side of the lens and the surface made of a bandage - And / or filler is formed and / or curable.
- This provides support for the lens, which is used to process the second side guaranteed.
- a device for signing and / or marking the lens is provided. This ensures that the lens is positioned later in a component, such as an eyeglass frame.
- the signing takes place either in a cutting unit by a tool and / or in a transformer unit by a laser.
- the marking also serves to position the lens relative to the holding device, provided that the reference is not guaranteed by the reclamping device during reclamping.
- a washing and / or rinsing device is provided for the lens.
- the first side of the lens can thus be cleaned before reclamping and the finished lens before removal.
- the washing and / or rinsing device is provided in a polishing unit.
- the reference surface is arranged orthogonally or parallel to the optical axis of the first side and / or the second side of the lens.
- the orthogonally arranged reference surface serves for vertical alignment, the parallel arranged reference surface determining the radial position of the lens. It is also possible to ensure the alignment of the lens in the vertical and radial directions over a shaped surface.
- the task is solved by the following process steps: Clamping the lens blank in a lens holder or holding device which can be rotated about a workpiece spindle axis. Working out a first optically active surface with an optical axis on the first side of the lens blank. Generating a clamping shoulder with a cylindrical lateral surface, the axis of which lies essentially in the workpiece spindle axis, this step also being able to take place before the first optically active surface is worked out.
- Another method therefore provides for the following steps. Clamping the lens blank in a lens holder rotatable about a workpiece spindle axis. Working out a first optically active surface with an optical axis on the first side of the lens blank, the optical axis of this surface lying essentially in the workpiece spindle axis. Generating a clamping shoulder with a cylindrical outer surface and an annular support surface, the axis defined by the outer surface and the annular surface being offset and / or tilted relative to the optical axis of the first optically active surface, this step also taking place before the first optically active surface is worked out can. Removal and turning of the previously processed lens blank.
- the second surface is now machined, with its optical axis coinciding with the workpiece spindle axis.
- the description of the invention speaks of an optical axis of a varifocal surface, it means an axis that describes the mean curvature of the varifocal surface and is based on the optical axis of the underlying symmetrical base surface.
- the clamping shoulder has a cylindrical outer surface and an annular support surface running perpendicular thereto.
- the outer surface is gripped by pliers or holding parts of a lens holder or holding device in order to hold the lens blank in a rotationally fixed manner, the bearing surface resting on the systems of the holding parts. Since the normal of the support surface is tilted with respect to the blank axis and the upper end or the contact of the holding parts or their contact lies in a counter surface running perpendicular to the workpiece spindle axis, the lens blank is held in the lens holder with an axis tilted with respect to the workpiece spindle axis.
- the main surface axes of the two sides must be correlated with one another. This can also be taken into account in the clamping shoulder by incorporating a phase marking, which interacts mechanically or optically with a corresponding counter marking on the lens holder, into the clamping shoulder. This makes it possible to insert the turned lens blank into the lens holder precisely in phase to be used so that the control, which knows the relative position of the workpiece spindle to the machining tool, thus also receives information about the phase alignment of the lens blank and can thus effect phase-correct machining of the second side.
- one or more line markings or signatures are also incorporated, which make it possible to set and check the angular position of the two optical surfaces relative to one another for processing the second page.
- Such line markings also called signatures, are also applied on the second page.
- the line markings contain in particular information about the position of the major and minor axes of the lens base. Markings on both sides are mainly required for edge processing of spectacle lenses, which have to be inserted in the spectacle frames precisely in phase.
- the lens is optionally provided with a position feature having a reference to the first side and / or the second side by means of the cutting process and the lens after the cutting and / or after the polishing of a first side and before removal from the first holding device or before the first holding device is released from a second holding device and aligned relative to the second holding device by means of the positioning feature.
- the positioning feature can also be used here be incorporated as a phase marker in the clamping shoulder, so that a precise insertion of the turned lens blank is possible.
- polishing includes the finest diamond processing or processing without additives, only with water. As a result, minimal cutting marks are revised or removed.
- a receiving adapter arranged on the second side of the lens for processing the first side is possibly detached from the second side of the lens and the second side of the lens is processed by the cutting and / or polishing unit.
- the first side or the first receiving surface or the support part for processing the first side serves as a position feature for processing the second side.
- the lens is clamped in the radial direction by holding parts of the second holding device, the positioning feature of the lens designed as a reference surface being brought into contact with at least one holding part or a contact of the holding part.
- the system is point-shaped, line-shaped or flat, so that the reference surface can be created.
- the reference surface is arranged perpendicular or parallel to an optical axis of the lens and that a support part is brought into contact on the first side.
- the support part has a plastic elastic surface, which is hardened after application, so that the lens is supported without tension.
- a marking and / or signing for later alignment of the lens is placed or incorporated on the first side and / or on the second side, a protective layer or a protective film being arranged on the first side after processing .
- the signing can be done by a laser immediately before reclamping or with the cutting or milling process.
- the marking also serves to position the lens relative to the holding device, provided that the reference is not guaranteed by the reclamping device during reclamping.
- the phase position of the lens relative to a further lens or relative to the spectacle frame or to the transformer device is ensured by the signature.
- the lens is washed after processing the first side or after polishing and before applying the protective layer or the protective film, and the first side and / or the second side is provided with a coating. For practical reasons, coating both sides at once is of greater importance.
- the lens is held by the clamping jaws of the second holding device after the processing of the first side and before removal from the first holding device.
- the position of the lens relative to the first holding device is thus from the system control to the second holding device transferable.
- the use of signatures and / or markings can be omitted.
- the lens is detached from a receiving adapter after processing the first side and / or is detached from a support part after processing of the second side. This ensures the processing or completion of the lens after the respective processing step.
- edge processing is carried out before or after coating for later positioning and attachment of the lens to the spectacle frame.
- Edge processing after coating removes critical coating areas in the edge area and creates special attachment options by rounding the shape, grooving and drilling the lens for attachment to the eyeglass frame.
