Abstract
Description
[Technical Field]
[0001] The present invention relates to a gripping device for releasably holding a lens, a handling system including said gripping device and a handling device for movably transporting said gripping device, and a machine for processing lenses having the handling system and at least one processing unit for processing the lens. [Background technology]
[0002] The technical field of this application is the manufacture of lenses, such as eyeglass lenses and other optical lenses. Such manufacture typically takes place in an optical facility or similar facility through several processes. Lenses are typically provided uncut, i.e., as circular pieces of material, and then machined to accommodate a defined lens function (e.g., a specific prescription). The thus-machined lens body is then finally edged (i.e., machined to a desired peripheral contour), e.g., for fitting the lens into a corresponding eyeglass frame or similar. For machining, the lens is clamped or gripped at its circumferential edge, leaving the opposite lens surface exposed for machining. Lenses machined as described above are often cleaned before being edged. During edging, the lens is contoured along its circumference to fit the corresponding frame. After edging, the lens is typically cleaned (again). During several stages of processing, the lens is inspected to detect defects, irregularities, or imperfections that may affect the functionality of the lens. Before inspection, the lens is typically cleaned to prevent airborne particles (dust, debris, etc.) from being mistaken for optical defects. Therefore, both cleaning and inspection play a key role in ensuring lenses meet required specifications for clarity, precision, and performance. These processes are crucial to achieving high-quality lenses for a variety of applications, from eyeglasses to cameras to scientific instruments.
[0003] The processing process requires reliable transportation of the lenses to allow for accurate processing, cleaning, and inspection, and to avoid loss of the lenses due to improper holding.
[0004] There are known carriers designed to precisely receive conventional standardized initial circular lens blanks before they are edged. After edged, the processed lenses vary in shape, circumferential profile, and thickness, making transportation of each lens difficult and resulting in a substantial risk of losing the lenses from the carrier during transport to various processes. Summary of the Invention [Problem to be solved by the invention]
[0005] It is therefore an object of the present invention to provide a gripping device, handling system and machine that allows for securely and releasably holding lenses of any desired shape during the lens processing process (including machining, edging, cleaning and / or inspection).
[0006] This object is achieved by the subject matter of the independent claims. The dependent claims develop further the central idea of the invention. [Means for solving the problem]
[0007] According to a first aspect, the present invention relates to a gripping device for releasably holding a lens, preferably an eyeglass lens or any other type of optical lens, during a lens processing process (including cleaning and / or inspection and / or preferably machining and / or edging). The gripping device comprises two gripping parts facing each other and defining a receiving space extending in a receiving surface between the two gripping parts for receiving a lens. The gripping parts are configured to be movable relative to each other to change the distance between the gripping parts and thereby change, i.e., increase or decrease, the size of the receiving space for clamping a received lens between the gripping parts. One of the gripping parts comprises one or more gripping elements. The other gripping part comprises (at least) two gripping elements, spaced apart from each other, each gripping element facing the one or more gripping elements and all of the gripping elements being exposed towards the receiving space.
[0005] Thereby, all gripping elements cooperate to divide the receiving space into portions and contact the lens or lenses received in the receiving space so as to be clamped by the gripping parts. The other gripping part comprises a carrier, on which both gripping elements are arranged in fixed positions relative to each other. Preferably, the carrier is therefore arranged outside the receiving space. The carrier is arranged to be pivotable about a pivot axis extending (substantially) perpendicular to the receiving surface. Both gripping elements are arranged offset from the pivot axis so as to oscillate around the pivot axis when the carrier pivots around the pivot axis.
[0008] The two relatively movable gripping parts can accommodate lenses of different sizes and diameters. The presence of gripping elements on each gripping part allows for a designated clamping area or point, ensuring secure holding of the lens. Since one gripping part includes at least one gripping element and the other includes (at least) two gripping elements, at least three gripping elements are provided, ensuring highly precise gripping of the lens clamped between them. Furthermore, the pivotable design of the carrier with two gripping elements allows it to easily adapt to the shape of the lens to be clamped, ensuring precise and therefore secure gripping. The gripping device can therefore reliably and securely clamp lenses regardless of the lens's circumferential contour and / or thickness, etc.
[0009] To releasably hold—e.g., grab, clamp, or transport—a lens, the two gripping elements move to define the size of the receiving space capable of receiving the lens. Thus, the two gripping elements can be moved to an open position or a spaced-apart position, e.g., a maximum distance position and / or a position in which the receiving space is at its most expanded size. The gripping device is then positioned so that all gripping elements face the periphery of the lens to be clamped, and the lens is placed between the two gripping elements so that the lens can be received within the receiving space. The two gripping elements can then be moved closer to each other and to the periphery of the lens, i.e., narrowing the receiving space. At least one of the gripping elements has a pivotally arranged carrier, so that when the gripping element contacts the lens (i.e., the edge of the lens), the carrier pivots about its pivot axis, causing the two gripping elements arranged on the carrier to swing about the pivot axis until they contact the lens (i.e., the edge of the lens). The fixed relative positions of these two gripping elements, plus one other gripping element located on the opposite side of the lens relative to the receiving space, result in the lens being securely clamped at three points around its circumference, thereby ensuring a releasable retention of the lens during the lens processing process (including machining, edging, cleaning, and / or inspection), regardless of the lens shape.
[0010] Furthermore, one gripping part can be configured such that two of the one or more gripping elements are spaced apart from each other and face the two gripping elements of the other gripping part. The one gripping part includes another carrier, and the two gripping elements of the one gripping part are arranged on the other carrier in fixed positions relative to each other. The other carrier is also arranged to be rotatable about another pivot axis extending (substantially) perpendicular to the receiving surface. Furthermore, both of the two gripping elements of the one gripping part are arranged offset from the other pivot axis so as to oscillate about the other pivot axis when the other carrier pivots about the other pivot axis. Thus, both gripping parts are similarly designed to have a carrier and two corresponding gripping elements, which allows the gripping device to adapt with high precision to any shape of the lens to be clamped.
[0011] The one and / or the other gripping part is / are each arranged on one gripping finger, preferably at its distal end, which allows the gripping part to be positioned as desired and is large enough for the receiving space to receive lenses of any desired size.
[0012] The gripping fingers of said one and / or the other gripping part are movably arranged so that the size of the receiving space can be changed. Since it is the gripping fingers that are movable to change the size of the receiving space, a corresponding movement can be easily applied to the gripping parts via the respective gripping fingers. The gripping fingers can be designed in any desired way, so that the movement of the gripping fingers can be easily transmitted to the gripping parts without affecting or interfering with the receiving space.
[0013] The gripping elements, preferably the gripping fingers of the gripping elements, if any, are arranged to be movable about their respective pivot axes so that the size of the receiving space can be varied. This allows a defined and highly precise movement and therefore a highly precise gripping function. In combination with the corresponding gripping fingers, an effective movement can be achieved which corresponds to the length of the gripping fingers or the distance between the pivot axis of the gripping element and the other gripping element.
[0014] The pivot axis can be located at the proximal end of each gripping finger, thus allowing for very effective mobility of the gripping fingers.
[0015] The pivot axis can extend (substantially) perpendicular to the receiving surface, so that the gripping parts or elements can be moved effectively in the plane in which the receiving space preferably spans, thus allowing a highly precise gripping function regardless of the distance between the gripping parts.
[0016] If both the one gripping part and the other gripping part, preferably both their associated gripping fingers, are pivotally arranged, their associated pivot axes can be offset relative to one another in the receiving plane. Thus, the receiving space can be precisely defined and a corresponding mobility can be effectively provided, allowing for a very effective clamping function. Furthermore, the receiving space can be set according to the desired lens dimensions of the lens to be processed.
[0017] When the one gripping part and the other gripping part, preferably both of their associated gripping fingers, are movably arranged, their movement can be linked together, preferably so that both can be selectively moved towards or away from each other. By linking the gripping parts or gripping fingers movably, a single movement action is obtained that effectively allows relative movement between the gripping parts. Thus, the size of the receiving space can be easily and effectively changed.
[0018] Both the one gripping part and the other gripping part, preferably both their associated gripping fingers, can be mechanically and movably connected at a connecting shaft, which can be radially shifted to move the gripping parts and change the size of the receiving space. Therefore, the mobility of the gripping parts or gripping fingers after connection can be achieved with high precision, thereby achieving precise gripping and clamping functions. Furthermore, by moving the connecting shaft, movement can be easily applied to this very single connecting shaft, resulting in a very effective and easy control function of the gripping parts or gripping fingers.
[0019] The connecting shaft can extend parallel to each pivot shaft, which allows for easy layout and effective clamping function. The connecting axis can preferably be arranged between the pivot axes, so that the gripping device can provide effective control of the movement function and thus the change of the receiving space in a compact manner, preferably with low applied forces.
[0020] The gripping device may further comprise an actuator for moving the gripping parts relative to one another, so that the gripping device has an actuator which is sufficient and therefore effective and precisely arranged to simplify the functioning of the gripping device.
[0021] The actuator can be configured to radially shift the connecting shaft and preferably has a rod for acting radially on the connecting shaft, thus allowing easy control of the gripping device, preferably by means of simple and common means such as a rod.
[0022] The gripping device may further comprise a spring element for spring-biasing the gripping parts relative to one another, so that the lens is securely clamped by the gripping device, the clamping force is easily applied, and the gripping parts are provided pre-tensioned in the direction of the closed position or the position with the smallest receiving space, and thus in the clamping direction, preferably without the need for additional and / or external supporting clamping force.
[0023] The gripping elements can be made of a high-friction material, preferably rubber, so that a high frictional force acts on the lens, enabling a secure gripping function. When made of rubber or a similar soft, high-friction material, the gripping elements can be designed to have both a high clamping capacity and a low risk of damaging the lens during handling.
[0024] The gripping device may further comprise a base for carrying the gripping parts, preferably via gripping fingers connected, preferably movably connected, to the base, In this way the gripping device can be easily adapted and operated, for example for storage, handling, shipping, assembly, etc.
[0025] The gripping device further includes a sealing barrier, which is arranged to spatially separate the gripping element side of the gripping part from a distal portion of the gripping part (e.g., the proximal end of the gripping fingers) away from the receiving space. Therefore, the gripping device can be easily and safely used even in an environment where a liquid is used on the lens side (e.g., for cleaning or processing the lens). Therefore, the gripping device, e.g., its mounting portion and actuator side, can be protected, and the life of the gripping device can be extended.
[0026] The gripping device may further comprise a connection for attaching the gripping device to a handling device, preferably a conveyor such as a carousel, thereby allowing the gripping device to be easily attached to a corresponding handling device and thus facilitating assembly.
[0027] The base may include the connecting portion, whereby the connecting portion can be provided on a stable support, resulting in a stable and therefore highly accurate gripping and clamping function.
[0028] According to another aspect, the invention relates to a handling system comprising a gripping device as described hereinabove and a handling device for movably transporting said gripping device.
[0029] The advantages described for the gripping device can therefore be applied to any type of handling system that allows the gripping device to be movably mounted, thus allowing an effective and precise gripping function to be applied to any mobile handling system.
[0030] The gripping device can be attached to the handling device by a connection, which allows the gripping device to be easily attached to the handling device and therefore provides a stable connection, allowing for accurate clamping and manipulation, i.e. handling, of the lens.
[0031] The handling device can be a conveyor, preferably a carousel, so that the gripping device can be installed in known conveyor systems and its function can be easily adapted to retrofit existing conveyors.
[0032] The handling system may further comprise actuators for moving the gripped parts relative to one another, whereby the actuator functions can be provided separately from the gripping device, resulting in a simpler layout of the gripping device, a reduced number of parts and therefore easier to use.
[0033] The actuator may be arranged to move the connecting shaft radially, and more preferably comprises a rod for acting radially on the connecting shaft. The actuator can thus be provided for simply and effectively applying a respective actuation force to move the gripping parts. The use of a rod can provide a very simple yet effective actuation means.
[0034] According to another aspect, the present invention relates to a machine for processing lenses, the machine comprising a handling system as described hereinabove. Furthermore, the machine comprises at least one processing unit for processing, preferably machining and / or edging and / or cleaning and / or inspecting, lenses releasably held by the gripping device. The handling device is configured to move the lens held by the gripping device to the processing unit in order to enable corresponding processing of the lens while the lens is held by the gripping device.

[0036] Each figure shows a different perspective view of a gripping device 1 according to the invention for releasably holding a lens L, preferably a spectacle lens or any other type of optical lens, during the lens processing process.
[0037] The gripping device 1 comprises two gripping parts 2, 3 facing each other, which define a receiving space S extending to a receiving surface P between the gripping parts 2, 3 for receiving a lens L. This is clearly shown in Figures 1 to 5 and 10. The gripping parts 2, 3 are arranged to be movable relative to one another to vary the distance D therebetween, thereby varying, i.e. increasing or decreasing, the size of the receiving space S in which the lens L received between the gripping parts 2, 3 can be clamped. The relative mobility of the gripping parts 2, 3 is indicated, for example, by the two arrows A in Figure 3.
[0038] One of the two gripping parts (hereinafter also referred to as one gripping part) 2 includes at least one gripping element 20, as is clear from FIGS. The other of the two gripping parts (hereinafter also referred to as the other gripping part) 3 includes two gripping elements 30 arranged at a distance from each other (see Figures 3 to 5 and 10), and each gripping element 30 faces towards at least one gripping element 20. This allows the gripping elements 20, 30 to be exposed towards the receiving space S, i.e., the gripping elements 20, 30 partially delimit the receiving space S, and allow the lens L received in the receiving space S to be in contact with the lens L and clamped by the gripping parts 2, 3.
[0039] The gripping elements 20, 30 are preferably made from a high friction material such as rubber. The other gripping part 3 comprises a carrier 4. The two gripping elements 30 are both arranged on this carrier 4 in fixed positions relative to each other. The carrier 4 is arranged to be pivotable about a pivot axis X extending substantially perpendicular to the receiving surface P. When the carrier 4 pivots about the pivot axis X, both of the two gripping elements 30 are arranged offset from the pivot axis X so as to swing about the pivot axis X.
[0040] As shown in the figure, the at least one gripping element 20 is shown here as only one gripping element. Alternatively, one gripping part 2 may have two at least one gripping elements 20, spaced apart and facing the two gripping elements 30 of the other gripping part 3. The one gripping part 2 includes a separate carrier (not shown), on which the two gripping elements 20 of the one gripping part 2 are arranged in fixed positions relative to each other. The separate carrier is also arranged to be rotatable about a separate pivot axis (not shown) extending substantially perpendicular to the receiving surface P. Both of the two gripping elements 20 of the one gripping part 2 are offset from the separate pivot axis so that they oscillate about the separate pivot axis when the separate carrier pivots about the separate pivot axis. In other words, the two gripping parts 2, 3 may be designed or provided in a similar or identical configuration.
[0041] The one and / or the other gripping part 2, 3 is respectively arranged on the gripping finger 5, preferably on the distal end 50 of the gripping finger 5. One or both of the gripping fingers 5 of the one and / or other gripping parts 2, 3 are movably arranged so that the size of the receiving space S can be changed. In the embodiment shown, both of the gripping fingers 5 of the one and / or other gripping parts 2, 3 are movably arranged accordingly so as to change the size of the receiving space S.
[0042] One and / or the other gripping part 2, 3 and / or the respective gripping finger 5 can be arranged to be movable about a respective pivot axis Y in order to vary the size of the receiving space S. In the embodiment shown, both gripping parts 2, 3 or both gripping fingers 5 have a pivot axis Y as described above.
[0043] The pivot axis Y may be located at the proximal end 51 of each gripping finger 5, as exemplarily shown in FIGS. The pivot axis Y can extend substantially perpendicular to the receiving space S or the receiving surface P, as can be seen in FIGS. If both the one and the other gripping parts 2, 3, and preferably both their associated gripping fingers 5, are arranged to be pivotable, the pivot axes Y can be offset from one another in the receiving plane P, as can be inferred from Figures 3, 5 and 9.
[0044] If both the one and the other gripping parts 2, 3, preferably both their associated gripping fingers 5, are arranged to be movable, their movements can preferably be coupled to one another so that both can be selectively moved towards or away from one another. Both the one and the other gripping parts 2, 3, and preferably both their associated gripping fingers 5, can be mechanically movably connected at a connecting axis Z, so that the connecting axis Z can be shifted radially to move the gripping parts 2, 3 and change the size of the receiving space S.
[0045] The connecting axis Z may extend parallel to each pivot axis X. Preferably, the connecting axis Z may be located between both pivot axes X, as can be seen from Figures 3 and 9.
[0046] The gripping device 1 may further comprise an actuator for moving the gripping parts 2, 3 relative to one another, which may be arranged to radially shift the connecting axis Z and preferably has a rod for acting radially on the connecting axis Z.
[0047] The gripping device 1 may further include a spring element 6 for spring-biasing the gripping parts 2, 3 relative to one another. The spring element 6 is exemplarily shown in FIGS. 3 and 9. Here, a spring 60 acts on a plate 61, which in turn acts on both the fingers 5 or the gripping parts 2, 3, spring-biasing them relative to one another. That is, in the closed position, the size of the receiving space S is defined to be smallest. Therefore, clamping of the lens L can be achieved without the application of additional active external forces.
[0048] The gripping device 1 may further comprise a base 7, which carries the gripping parts 2, 3, preferably via gripping fingers 5 connected (preferably movably connected) to the base 7. This can be seen in the exemplary views of Figures 4-10.
[0049] The gripping device 1 may further comprise a sealing barrier 8 arranged to spatially separate the gripper parts 2, 3 or their gripping elements 20, 30 and a distal part of the gripping device 1, e.g., the proximal end 51 of the gripping fingers 5, from the receiving space S. This can be seen in the exemplary illustrations of Figures 4 and 9.
[0050] The gripping device 1 may further comprise a coupling 9 for attaching the gripping device 1 to a handling device 11, preferably a conveyor such as a carousel. The base 7 may also comprise the coupling 9.
[0051] 1-3 are diagrams illustrating a handling system 10 according to the present invention. The handling system 10 comprises a gripping device 1 according to the invention and a handling device 11 for movably transporting the gripping device 1 . The gripping device 1 can be attached to a handling device 11 by means of a connection 9, as exemplarily shown in FIG.
[0052] The handling device 11 may include a conveyor 12, preferably a carousel. The handling system 10 may further comprise an actuator 13 for moving the gripping parts 2, 3 relative to one another. The actuator 13 is preferably arranged to radially shift the connecting axis Z by having a rod 14 for acting radially on the connecting axis Z, as exemplarily shown in Figure 3.
[0053] 1-3 illustrate a machine 100 for processing a lens L according to the present invention. The machine 100 comprises a handling system 10 with a gripping device 1. The machine 100 further comprises at least one processing unit 101, 102, 103, 104 for processing, preferably machining and / or edging and / or cleaning and / or inspecting, the lens L releasably held by the gripping device 1. The handling device 11 is configured to move the lens L held by the gripping device 1 to the (at least one) processing unit 101, 102, 103, 104, allowing a corresponding processing treatment of the lens L while it is held by the gripping device 1.
[0054] The present invention is not limited to the above-described embodiments, provided that it falls within the scope of the appended claims.
