Description

The present invention relates to an apparatus for processing, in particular polishing, an optical lens according to the preamble of claim 1 and a method for processing, in particular polishing, an optical lens.

An optical lens, for example for glasses, should have certain optical properties. The associated desired optical data of the lens are determined, for example, by an optometrist. The lenses are then machined or fabricated depending on the respective desired optical data, wherein the lenses are provided in particular with so-called free-form surfaces (for example, progressive lenses, etc.). The following description and the present invention preferably relate to such lenses or lens blanks which are processed in accordance with the desired, individualized optical data and in particular provided with so-called free-form surfaces.

The present invention is particularly preferably concerned with the machining or polishing of an optical lens. In general, this also applies to the processing or polishing of another optical component, such as a mirror or the like. Accordingly, the term "optical lens" is preferably also to be understood in a broad sense as meaning that it also includes other optical components. In the following, however, the focus is always only on the processing or polishing of an optical lens. The relevant explanations and explanations therefore preferably also apply correspondingly for the processing or polishing of another optical component.

The DE 10 2007 042 667 A1 shows an optical lens polishing apparatus. The polishing apparatus has two receptacles for holding the blocked lenses to be polished and associated motors for rotating the lenses during processing. The lenses, with their surface to be polished during processing at least substantially down and are located in a working space. The receptacles and the associated motor are each arranged on a U-shaped pivot arm, which is outside the working space stored and very limited pivotable about a horizontal pivot axis. The motors are arranged on the pivot arms outside the working space. The polishing apparatus has polishing tools arranged under the lenses, which are each rotatable by an associated rotary drive. The axes of rotation are vertical. The polishing tools are axial, so deliverable in the vertical direction. The pivot arms are arranged on a carriage and movable in the horizontal direction, so that a transverse adjustment of the lenses is made possible relative to the polishing tools.

The present invention has for its object to provide an apparatus and a method for processing, in particular polishing, an optical lens, wherein a simple and / or robust construction is made possible or facilitated, wherein a change of the lens is facilitated or simplified and / or a larger pivoting of the lens to be machined relative to the associated tool is made possible or facilitated with a simultaneously compact construction of the device.

The above object is achieved by a device according to claim 1 or a method according to claim 14. Advantageous developments are the subject of the dependent claims.

One aspect of the present invention is that a receptacle for a lens by means of a push rod adjustment about a pivot axis transverse to the axis of rotation of the lens is pivotable. In particular, the motor is arranged together with the receptacle in a working space and particularly preferably pivotable together with the receptacle. This allows a compact construction and over the prior art greater pivoting of the lens to be processed. In particular, lenses and / or lenses with longer side areas, such as sports glasses or fashion eyewear, which are better adapted to a head shape, can be machined or polished, since, according to the proposal, larger machining and pivoting paths are made possible than in the prior art. Furthermore, a simple and / or robust construction is made possible.

According to a further aspect of the present invention, the lens changing lens is pivoted upward such that the recording has upwards and / or the lens is changeable from above. This significantly facilitates changing the lens, especially when changing the lens manually. Furthermore, this allows or facilitates a compact construction.

According to another aspect of the present invention, the tool is rotated about an at least substantially horizontal axis, wherein the lens rotates about an axis of rotation that is tilted or tilted relative to the axis of rotation, and wherein the lens is displaced or displaced in the vertical direction. This allows a simple, robust and / or compact design. Furthermore, a change of lens and tool is facilitated or simplified. In particular, the lens and the tool for changing in the vertical direction can be moved apart and / or pivoted to each other, in particular pivoted away from each other.

According to yet another aspect of the present invention, the receptacle or lens is pivotable relative to the rotational axis of the tool, particularly preferably substantially at 90 °, so that a lateral change of the lens or a change of the lens is facilitated or made possible from above. This facilitates or enables a compact construction. In particular, in fact a linear extension of the receptacle or lens on the one hand and the tool or rotary drive of the tool on the other hand is only required to a limited extent. Furthermore, an independent change of lens on the one hand and tool on the other hand, particularly preferably by means of corresponding changing devices for automated changing, made possible or facilitated.

Particularly preferably, the axis of rotation of the tool extends at least substantially horizontally. This is conducive to a compact design.

The proposed device and the proposed method allow in particular the realization of a low structure and / or an operation from above, particularly preferably by a laterally adjacent or standing in front of users. This not only facilitates the operation but in particular also a cleaning of the work space.

Particularly preferably, the drive or the drives are arranged for the push rod adjustment outside the working space and in particular below the working space. This is the preferred accessibility or operation from above and / or a low construction conducive.

Some of the foregoing and following aspects and features of the present invention may be combined as desired, but also independently.

The device 1 preferably has a lens drive 5 for rotating the lens 2 to be processed, that is to be polished. The lens 2 is rotatable about an axis of rotation R by means of the lens drive 5.

In the illustrated example, the device 1 preferably has two lens drives 5 in order to be able to polish two lenses 2 at the same time in the illustrated example. In principle, however, a common lens drive 5 can also be provided for two lenses 2.

The or each lens drive 5 in the illustrated embodiment preferably has a receptacle 5A for holding or clamping the associated, preferably blocked lens 2, particularly preferably a block piece 2A of the lens 2, and an associated motor 5B for driving or rotating the associated receptacle 5A or Lens 2 on. Alternatively, the receptacle 5A may also directly receive, hold or clamp the lens 2.

The lens drive 5 or the motor 5B is preferably arranged together with the associated receptacle 5A in the working space 1A. In the illustrated example, therefore, two lens drives 5 or motors 5B for driving the lenses 2 are arranged in the working space 1A of the device 1.

The device 1 is preferably designed such that the receptacle 5 A or the lens drive 5 - that is, in particular, together with the associated motor 5 B - is pivotable about a pivot axis S. The pivot axis S preferably runs transversely, in particular perpendicular, to the rotation axis R. The pivot axis S preferably intersects the axis of rotation R or axes of rotation R.

In the illustrated example, the two receptacles 5A or lens drives 5 are preferably pivotable about the common pivot axis S and / or only together.

The device 1 preferably has a push rod adjustment 6 for holding and / or pivoting the lens drive 5 or motor 5B or the lens (s) 2, receptacle (s) 5A or lens drives 5 and / or motors 5B.

Fig. 2 shows the device 1 and the push rod adjustment 6 in a schematic section along line II-II of Fig. 1 So in a vertical section. Fig. 3 shows a schematic side view of a lower part of the push rod adjustment. 6

The push rod adjustment 6 preferably serves the already mentioned pivoting of the receptacle (s) 5A and the lens (s) 2 about the pivot axis S. The push rod adjustment 6 has for this purpose preferably a push rod 6A, as in Fig. 2 indicated. The push rod 6A may be formed in one or more parts.

The push rod 6A preferably engages an eccentric or pivot arm 6B to translate or convert the at least substantially linear push rod movement into a pivoting movement. The push rod 6A is pivotally connected to the pivot arm 6B in the illustrated example via a hinge 6C. The pivot arm 6B is rotatably connected, for example via a shaft portion 6D and / or a holder 6E with the lens drive 5 and two brackets 6E the lens drives 5 rotatably connected.

The brackets 6E are preferably formed angularly in the representation example, as in particular from Fig. 1 seen. The brackets 6E, for example, each fixed to the associated motor 5B and hold it. The motor 5B, in turn, rotatably supports the associated receptacle 5A.

The push rod adjustment 6 preferably has a retaining element 6F, which is particularly hollow and / or tubular in the illustrated embodiment, and / or a retaining head 6G, particularly preferably for pivotal mounting of the pivot arm 6B, here in particular via the shaft section 6D. In the illustrated example, the holding element 6F carries the holding head 6G at its end projecting into the working space 1A.

The pivot bearing or the pivot arm 6B and the push rod 6A are preferably encapsulated in the working space 1A or protected or covered, in the illustrated example by the push rod 6A receiving or giving holding element 6F and / or the holding head 6G. Particularly preferably, the holding head 6G is connected to the hollow holding element 6F such that it closes it. The holding head 6G is in the illustrated embodiment preferably in turn by a removable cover 6H or the like - particularly preferably on the top - closed.

The holding element 6F and the push rod 6A are preferably led out of the working space 1A or end outside.

The push rod adjustment 6 or, the holding element 6F is preferably through an opening, in particular a bottom 1B of the device first or the working space 1A, led out of the working space 1A. For sealing, a corresponding sealing element, here a bellows 6I is preferably provided, which is fastened on the one hand on the wall or the bottom 1B and on the other hand on the holding element 6F or holding head 6G end in the representation example. In particular, the sealing element or the bellows 6I is designed such that a linear or axial movement of the push rod adjustment 6 or holding element 6F, in the representation example in the vertical direction or in the X direction, as indicated by an arrow in FIG Fig. 2 implied, without affecting the seal is possible.

The device 1 or the push rod adjustment 6 preferably has a first drive 7 for at least substantially linear adjustment or displacement of the receptacle (s) 5A or lens (s) 2 or the push rod adjustment 6 or the pivot axis S, in particular transversely to the axis of rotation D, in the vertical direction and / or in the X direction, as shown in the schematic side view of a lower part of the device 1 and the push rod adjustment 6 according to Fig. 3 seen.

The first drive 7 thus enables the process or the transverse feed of the lens 2 relative to the associated tool 3. In particular, a calculated or controlled linear axis X is formed.

In the illustrated example, the first drive 7 is preferably arranged outside the working space 1A, in particular below the bottom 1B and / or in a lower area of the device 1.

The device 1, the push rod adjustment 6 or the first drive 7 preferably has a first slide 8 for the linear guidance of the push rod adjustment 6 or holding element 6F. The first carriage 8 thus allows the adjustment or displacement in the X direction. In the illustrated example, the holding element 6F is in particular in the region of its outer free end with the first carriage 8, optionally via a corresponding adapter, firmly connected, in particular screwed. Particularly preferably, the in particular plate-like formed first slide 8 connects laterally and / or in extension to the preferably elongated and / or hollow profile-like or tubular holding element 6F.

The first carriage 8 is in particular slidably guided on a base part 1C of the device 1 and / or a rail 8A, preferably in the X direction or in the longitudinal direction of the holding element 6F or push rod adjustment 6.

The first drive 7 is preferably designed as a linear drive.

In the illustrated embodiment, the first drive 7 preferably has a threaded spindle 7A for the linear adjustment of the first carriage 8. Particularly preferably, the first drive 7 has a ball screw drive, which is preferably formed by the threaded spindle 7A and an associated threaded part 7B, which engages with the threaded spindle 7A via at least one ball, not shown. The threaded portion 7B is connected to the first carriage 8 in the illustrated example.

The first drive 7 preferably has a first motor 7C for driving or rotating the threaded spindle 7A or the ball screw drive or another gearbox.

By corresponding rotation or rotation of the threaded spindle 7A, the first carriage 8 can thus be moved or displaced linearly or in the X direction in the illustrated example.

For detecting the position of the first carriage 8 and / or as a limit switch for limiting the maximum adjustment, the first drive 7 is preferably associated with a detection device 7D, which in the illustrated example comprises a particular motor-side switch and carriage-side stops, as in FIG Fig. 3 indicated schematically. However, other realizations are possible here.

The device 1 or the push rod adjustment 6 preferably has a second drive 9 for pivoting the receptacle (s) 5A or lens (s) 2 and / or for (linear) actuation or adjustment of the push rod 6A. The second drive 9 is preferably arranged outside the working space 1A, in particular below the bottom 1B and / or in a lower area of the device 1.

The device 1, the push rod adjustment 6 or the second drive 9 preferably has a second carriage 10 for linear movement or for actuating the push rod 6A. The second carriage 10 thus allows said pivoting about the pivot axis S.

Preferably, the second drive 9 engages the outer free end of the push rod 6A in order to be able to displace or displace the push rod 6A at least essentially in the X direction and thus to control the pivoting about the pivot axis S.

The push rod 6A is preferably articulated to the second drive 9 and second slide 10 via a hinge 6J. However, other constructive solutions are possible.

Preferably, the second drive 9 is arranged on the first carriage 8 and / or moved together with this. This ensures that no pivoting takes place about the pivot axis S in the linear adjustment in the X direction, ie in the cross feed, or when moving or by means of the first drive 7. Rather, the linear method or adjustment of the lens 2 relative to the tool 3 in the X direction on the one hand and the pivoting of the lens 2 relative to the tool 3 about the pivot axis S on the other hand independently by the first and second drive 7, 9.

Particularly preferably, a double slide arrangement is formed in the illustrated embodiment. The second carriage 10 is seated in particular on the first carriage 8.

The second carriage 10 is in particular slidably guided on the first carriage 8 or a rail 10A, preferably in the X direction or in the direction of the push rod 6A.

The second drive 9, in the illustrated embodiment, preferably has a threaded spindle 9A for the linear adjustment of the second carriage 10. The second drive 9 particularly preferably has a ball screw drive, which is preferably provided by the threaded spindle 9A and an associated threaded part 9B via at least one not shown Ball is engaged with the threaded spindle 9A, is formed.

The second drive 9 preferably has a motor 9C for driving or rotating the threaded spindle 9A or the ball screw drive or another gearbox.

By corresponding rotation or rotation of the threaded spindle 9A, the second carriage 10 can thus be moved or displaced linearly or in the X direction in the illustrated example.

For detecting the position of the second carriage 10 and / or as a limit switch for limiting the maximum adjustment, the second drive 9 is preferably associated with a detection device 9D, which in the illustrated example comprises a particular motor-side switch and carriage-side stops, as in Fig. 3 indicated schematically. However, other realizations are possible here.

It should be noted that the second drive 9 and second slide 10 in Fig. 2 in an upper position and in Fig. 3 is shown in a lower position.

Fig. 1 and 2 show the lenses 2 and lens drives 5 and recordings 5A and 5B motors in a processing position. The receptacles 5A and 2 have lenses to the associated tools 3 and at least substantially in the horizontal direction.

Fig. 4 shows in a schematic section similar to Fig. 2 an upper part of the device 1 and the working space 1A, wherein the lenses 2 or 5 or 5A recordings are pivoted upwards or 5 upward, ie in a change position.

To change the lenses 2 and / or tools 3, the working space 1A can be opened. The device 1 in particular has a cover 1D, which is preferably movable or pivotable on one side of the working space 1A and / or in the working space 1A, as in FIG Fig. 4 indicated by dashed lines. The cover 1D preferably forms a domed lid. However, other constructive solutions are possible.

The proposed device 1 and the proposed method provide particularly preferred that the shots 5A in particular together with the associated motors 5B - particularly preferably by means of the push rod adjustment 6 - from the processing position to the change position by an angle W, as in Fig. 4 indicated, are pivotable. The angle W is preferably at least substantially 90 °. In particular, pivoting takes place about the pivot axis S from the at least substantially horizontally aligned machining position, as in FIG Fig. 1 and 2 indicated in the at least substantially vertically oriented change position, as in Fig. 4 indicated, and vice versa.

The lenses 2 are therefore preferably insertable from above, removed and / or exchangeable. This facilitates changing the lenses 2.

In the illustrated example, the lenses 2 are particularly preferably held or clamped over their block piece 2A in the associated receptacle 5A. This can be done for example by a corresponding clamping device and / or by, for example, automated recording, clamping, suction, clamping or the like, for example by an electric motor, hydraulic or pneumatic drive.

Required supply lines 6K, for example, for the electrical power supply of the motors 5B and / or for automated recording, holding, sucking or clamping the lenses 2 or block pieces 2A or the like, in particular for electrical, pneumatic and / or hydraulic supply, are preferably by the push rod adjustment. 6 led into the working space 1A and / or inside the push rod adjustment 6, as in Fig. 2 indicated.

The supply lines 6K extend in particular through the holding element 6F and the holding head 6G and / or shaft section 6D and the adjoining holders 6E, as shown schematically in FIG Fig. 2 indicated. The supply lines 6K can run along the push rod 6A and / or preferably surround it helically. If necessary, the supply line 6K can also be fastened to the push rod 6A. However, other constructive solutions are possible here.

When machining or polishing the lenses 2, these or the rotation axes R can also be tilted relative to the axes of rotation D of the tools 3. In the proposed structure, this tilting can take place at any angle, theoretically up to 90 °, so that in particular there is no limitation of the tilt angle during machining as in the prior art. Accordingly, especially lenses 2 with very high dioptres can be optimally processed or polished.

In the change position, the lenses 2 are pivoted away from the tools 3. Accordingly, a change of the tools 3 is facilitated.

The changing of the lenses 2 and / or tools 3 can be done either manually and / or automatically, particularly preferably by changing devices, not shown.

On the other hand, changing the lenses 2 on the one hand and the tools 3 on the other hand can be carried out independently or separately, if necessary also simultaneously, particularly preferably by means of corresponding changing devices.

As already mentioned, the illustrated device 1 is preferably designed for simultaneous processing or simultaneous polishing of two lenses 2 and accordingly preferably also has two tools 3 which can be crosslinked in rotation for processing the two lenses 2. However, the device 1 can basically also be designed only for processing a lens 2. In this case, a single lens drive 5 is sufficient. This is then in particular on one side of the push rod adjustment 6 or holding head 6G arranged. The arranged on the other side lens drive 5 can be omitted. Accordingly, then only a single tool drive 4 is sufficient with a single tool 3. The previous versions and explanations, however, apply accordingly.

The tool 3 is preferably attachable to the tool drive 4 via a coupling 4A. This is in particular a plug-in coupling or the like.

The tool 3 is preferably deliverable relative to the lens 2, in particular in the Z-direction or horizontal direction or in the direction of the axis of rotation D, as in Fig. 1 . 2 and 4 indicated. This can be done in particular by appropriate axial delivery or adjustment of the tool drive 4 or a spindle 4B of the tool drive 4 or the like. The Z axis preferably runs parallel to the axis of rotation D.

The clutch 4A or spindle 4B is, if necessary, directly or indirectly, for example via a belt drive 4C, preferably driven by a motor 4D of the tool drive 4. In the illustrated example, the engine 4D extends through a rear wall 1E of the working space 1A into the working space 1A, as in FIG Fig. 2 and 4 indicated. The belt drive 4C and / or other components are preferably arranged outside the working space 1A, particularly preferably behind the rear wall 1E. However, other constructive solutions are possible.

Preferably, the tool 3 is pressed with a predetermined or adjustable force against the lens 2 to be polished or employed, here in the Z direction. The pressing or adjusting can for example be done pneumatically, by spring force or in any other suitable manner.

Further, the tool 3 or the clutch 4A is preferably such articulated with the tool drive 4 and its spindle 4B or the like connected or held that tilt the tool 3 to the rotation axis D and / or Z-direction and thereby to the respective surface of the create lens 2 to be polished and / or can fit. This is especially true a corresponding joint, such as a ball joint or universal joint provided.

The polishing is preferably carried out by lapping, in particular thus using a corresponding friction fluid-containing liquid, such as a so-called polishing milk or the like. Alternatively or additionally, the polishing can also be done by fine grinding. In particular, instead of lapping, only a fine finish may be used to finish the lens 2, in particular before a subsequent coating of the lens 2.

Basically, workpieces (lens 2) and tool (polishing tool 3) can also be reversed or a kinematic reversal can be realized.

The term "axis" - in particular with respect to the linear axes X and Z - is preferably understood in terms of terminology in CNC controls (numerical or computer-aided controls) as a controlled or controlled or calculated movement axis.

The device 1 preferably has an unillustrated programmable logic controller, CNC control or the like.

The supply of a polishing agent, such as the polishing milk, preferably takes place from obliquely above, for example via an in Fig. 4 Dashed lines indicated feed 11, and / or by the tool 3 and the tool drive. 4
