FIELD OF THE INVENTION
The present invention relates to the field of gemstones and jewelry, and in particular to systems for handling and analyzing gemstones with security and ease of repeatability.
BACKGROUND
Due to the large intrinsic value and small size of gemstones, it has long been difficult to ensure security and repeatability in terms of handling, analyzing, and identifying gemstones. One can classify and identify one particular gemstone, but scaling up the volume of gemstones handled increases the risk that one or several of the gemstones already identified and evaluated may be swapped out for lesser stones. Additionally when gemstones are cleaned and analyzed by hand, the process is timely and introduces further risk of human error.
This invention relates to improvements to existing systems and to solutions to some of the issues raised or not solved thereby.

DETAILED DESCRIPTION
Referring now to FIG. 1, there is shown a gemstone handling and analysis system 10 constructed according to one embodiment of the present invention. In this embodiment, the system 10 includes an enclosure 11 surrounding a platform 18. In the embodiment shown, the enclosure 11 includes a frame 14. The frame 14 supports side panels 16, enclosing the platform 18, and a top panel 17, positioned above the platform 18. Certain embodiments could also include a bottom panel that supports the platform 18. In the embodiment shown, the platform 18 is supported within the enclosure 11 by other means, as will be described more fully below. A small gap 18a may exist between the edges of the platform 18 and the side panels 16, but any such gap must be small enough, such as one inch or less, that a person could not reach through such a gap and access the platform without authority to do so.
The side panels 16 and top panel 17 of the enclosure 11 may be clear, so as to permit an operator to inspect operations on the platform 18. Alternatively, the side panels 16 and top panel 17 may be opaque, so as to maintain confidentiality regarding operations on the platform 18. Preferably at least one panel of the enclosure 11 is openable. In this embodiment, each openable panel comprises two panel portions that may slide past each other and form an overlap 19. In the embodiment shown, there are three panel sets that are openable, with overlaps 19a, 19b and 19c. In some embodiments, the openable panels may additionally be lockable, at least by means of some locking mechanism, or by utilizing a detector, such as a proximity reed switch, to detect the opening of the enclosure 11. This increases security in relation to gemstone insertion and removal. Some embodiments may further include an alarm that sounds whenever one of the panels is opened, or whenever one of the panels is broken. Alternatively, some embodiments may include openable panels that are not lockable.
The system 10 includes at least one gemstone imaging device 12 positioned below the platform 18. In some embodiments the gemstone imaging devices(s) 12 support the platform 18 in position, within the enclosure 11. In certain embodiments, two or more gemstone imaging devices 12a, 12b may be included. In some embodiments, the gemstone imaging devices 12a, 12b may be Brilliance Scope® imaging devices from GemEx Systems.
Mounted on the platform 18, within the enclosure 11, is an automated positioning system 20. While any suitable system, such as a conventional X-Y positioning system, may be used, the automated positioning system 20 in the embodiment shown is a robotic arm system. The inventors have found that the Model R12 robot from ST Robotics works suitably well.
FIG. 2 shows the platform 18 as shown in FIG. 1, without the enclosure 11. In this embodiment, the platform 18 may include the robotic arm 20, along with a plurality of processing stations, such as a repository station 30, a cleaning station 40, gemstone imaging stations 50a, 50b, and a holding plate 60. As will be explained in further detail below, the robotic arm 20 includes a working hand 24, having several tools or elements mounted thereon, to accomplish the various tasks described herein.
The embodiment shown in FIG. 2 may include two gemstone imaging stations 50a, 50b. This allows one gemstone to be analyzed at the first gemstone imaging station 50a while another gemstone is cleaned and taken to the second gemstone imaging station 50b for analysis. In other embodiments, more or fewer gemstone imaging stations may be included. As shown in FIG. 2, the platform 18 may also include a repository station 30. In addition to the processing stations shown in FIG. 2, FIGS. 21-24 schematically depict examples of further processing stations that the platform 18 may include, such as a scale 70, a gemstone color analyzer 80, a gemstone clarity analyzer 90, and/or a gemstone origin analyzer 100.
FIGS. 2A-25 illustrate the processing stations in further detail, as the system carries out various processes. FIGS. 3-4 show a first gemstone imaging station 50a. In FIG. 3, the robotic arm 20, carrying a hook element 51, moves towards a cover 52a of the first gemstone imaging device 12a. FIG. 3A then shows the robotic arm 20 using the hook element 51 to remove the cover 52a, revealing a plate 54a of the first gemstone imaging device 12a (FIG. 2). In the embodiment shown, when removing the cover 52a, the hook element 51 interacts with a loop formed on the cover 52a. In FIG. 4, the robotic arm 20 sets aside the cover 52a, leaving at least part of the plate 54a exposed and ready to accept a gemstone for analysis.
FIG. 2A shows an enlarged view of the repository station 30 where, in this embodiment, a series of gemstones 22 are first deposited upon entering the system 10. The repository station 30 includes an initial repository 32 having a support surface 36 for receiving the gemstones 22. In the embodiment shown, the repository station 30 may further include an uprighting mechanism 34. In this embodiment, the uprighting mechanism 34 is a brush element having soft bristles 35. The uprighting mechanism 34 slidably connects to the repository station 30 via a slider track 37. The slider track 37 may attach to the platform 18 and/or to the initial repository 32. In other embodiments, other forms of uprighting mechanisms or attachment means that permit back-and-forth movement over the support surface 36 may suffice, such as a linear motor or other type of motor. In this embodiment, the support surface 36 is comprised of a non-reflective, low-friction material, such as anodized aluminum. The support surface 36 may further include one or more raised ledges or ridges 38 that may aid in the uprighting process. In the embodiment shown, when in use, the uprighting mechanism 34 is moved by a tab tool 39 of the robotic arm 20, back and forth over the support surface 36 at a height such that contact between the bristles 35 and the gemstones 22 causes the gemstones 22 to move and interact with the raised ledges or ridges 38.
FIGS. 5-7 show the gemstone repository station 30 as the gemstone uprighting mechanism 34 uprights the gemstones 22 deposited in the initial repository 32. In FIG. 5, the gemstones 22 are positioned on the support surface 36, each in no particular orientation, and the gemstone uprighting mechanism 34 is still in an initial position. FIG. 6 shows the position of the uprighting mechanism 34 after the robotic arm 20 moves the uprighting mechanism 34 over the gemstones 22 for the first time. In this embodiment, the robotic arm 20 moves the uprighting mechanism 34 by fitting the tab tool 39 into a slot 34a of the uprighting mechanism 34 and moving the tab tool 39 in a direction that pushes the uprighting mechanism 34 over the support surface 36 along the slider track 37. Subsequently, the tab tool 39 pulls the uprighting mechanism 34 back over the support surface 36, as shown in FIG. 7. As the uprighting mechanism 34 moves back and forth over the gemstones 22, the bristles 35 of the uprighting mechanism 34 cause the gemstones 22 to move and come into contact with the raised ridges 38. In this embodiment, the interaction between the bristles 35, the gemstones 22, and the raised ridges 38 tends to reorient the gemstones 22 to their most stable position—table side down, pavilion side up, and the culet at the highest point.
In the embodiment shown, once the uprighting mechanism 34 has operated a first time, the robotic arm 20 moves to the position shown in FIG. 7A. In that position, a camera 26 attached to the robotic arm 20 views the gemstones and determines which ones are in the upright position, along with the location of each such upright gemstone. By means of a gemstone gripper tool 41, robotic arm 20 picks up a first upright gemstone 22a from the initial repository 32, as shown in FIG. 7B, for processing as described below. Once all upright gemstones have been picked up, the uprighting mechanism 34 may be operated again, to upright more of the gemstones, which are then taken by the gemstone gripper tool 41 for processing. This part of the process happens iteratively until there are no more stones on the support surface 36.
FIGS. 8-15 show the cleaning station 40 of the system 10. FIG. 8 shows the gemstone gripper tool 41 placing the first gemstone 22a on a cleaning stand 42. In this embodiment, the first gemstone 22a is held on the cleaning stand by means of vacuum, although other means of holding the first gemstone on the cleaning stand may be employed. The first gemstone 22a is oriented such that, when placed on the cleaning stand 42, the table side faces down on the stand and the pavilion side is exposed upward. FIG. 9 shows the robotic arm 20 with a cleaning tool 44, wetting the cleaning tool in a reservoir 45 filled with a cleaning solution 46. In practice, isopropyl alcohol is one cleaning solution that works well. In the embodiment shown, the reservoir 45 includes a sponge 47 positioned, at least partially, within the cleaning solution 46, so as to absorb the cleaning solution 46. To wet the cleaning tool 44, the robotic arm 20 presses the cleaning tool 44 into the sponge 47. Although a sponge is used in the present embodiment, other forms of absorbent materials may be used in other embodiments. Alternatively, some embodiments may utilize no absorbent material, and the robotic arm 20 may simply dip the cleaning tool 44 directly into the cleaning solution 46. In the embodiment shown in FIG. 9, the cleaning tool 44 is a brush. However, in other embodiments, the cleaning tool 44 may be a cloth or other form of cleaning tool. The important point is that the cleaning tool 44 polishes the gemstone and removes dirt and smudges.
In FIG. 10, the robotic arm 20 rubs the cleaning tool 44 against the pavilion side of the first gemstone 22a. In this embodiment, the cleaning stand 42 rotates at a suitable speed (by a suitable motor, such as a DC motor controlled by the same software that controls the robotic arm 20) as the robotic arm 20 moves the cleaning tool 44 to rub the first gemstone 22a. Alternatively, the cleaning stand 42 may remain stationary while the robotic arm 20 moves the cleaning tool 44 to rub the first gemstone 22a, or the robotic arm 20 may hold the cleaning tool 44 stationary against the pavilion side of the first gemstone 22a as the cleaning stand 42 rotates the first gemstone 22a at a suitable speed against the stationary cleaning tool 44. In this embodiment, cleaning tool 44 comprises a brush, although in other embodiments, another form of cleaning tool may be used. In FIGS. 11-12 the robotic arm 20 cleans the gemstone using a first polishing tool 48, rubbing the first polishing tool 48 against the pavilion side of the first gemstone 22a. In this embodiment, the cleaning stand 42 rotates at a suitable speed as the robotic arm 20 moves the first polishing tool 48 to rub the first gemstone 22a. Alternatively, the cleaning stand 42 may remain stationary while the robotic arm 20 moves the first polishing tool 48 to rub the first gemstone 22a, or the robotic arm 20 may hold the first polishing tool 48 stationary against the pavilion side of the first gemstone 22a as the cleaning stand 42 rotates the first gemstone 22a at a suitable speed against the (in this embodiment, stationary) first polishing tool 48. In the embodiment shown, the first polishing tool 48 comprises a cloth attached to one or more sides of a block, although in other embodiments, another form of polishing tool may be used.
FIG. 13 shows the robotic arm 20 removing the first gemstone 22a from the cleaning stand 42 by means of the gemstone gripper tool 41. In FIG. 14, the robotic arm 20 wets the first gemstone 22a, at least the table side, in the reservoir 45 of the cleaning solution 46. To wet the first gemstone 22a, the robotic arm 20 presses the first gemstone 22a into the sponge 47. Alternatively, the robotic arm 20 may simply dip at least the table side of the first gemstone 22a directly into the cleaning solution 46. In FIG. 15, the robotic arm 20 further cleans the first gemstone 22a by rubbing at least the table side of the first gemstone 22a against a second polishing tool 49. In the embodiment shown, the second polishing tool 49 is a cloth attached to a block, the block supported by the platform 18, although in other embodiments, another form of polishing tool may be used. Notice that, in this embodiment, the gemstone is maintained in substantially the same orientation throughout the cleaning process: the table side down, the pavilion side up, and the culet at the highest point.
In alternative embodiments, the cleaning station 40 may comprise different combinations of the above described cleaning and polishing tools. For example, in situations where the gemstones 22 have been pre-cleaned in cleaning solution before entering the system 10, the steps involving cleaning the gemstones 22 with the cleaning tool 44 and the cleaning solution 46 may be eliminated. Further, where the operator anticipates commonly pre-cleaning the gemstones 22 in cleaning solution 46 before depositing the gemstones 22 into the system 10, the reservoir 45 of cleaning solution 46 and the cleaning tool 44 may be eliminated altogether from the system 10. In such an embodiment, the first polishing tool 48 and/or the second polishing tool 49 can still be used to clean the gemstones 22 in order to remove any excess dust before the analysis process begins. The cleaning process improves the quality of the gemstone imaging analysis. When the gemstone clarity analyzer 90 is included on the platform 18 and it is desired to perform a clarity grading analysis, the cleaning process may also improve the clarity grading analysis.
FIGS. 16-17 show the first gemstone imaging station 50a. In FIG. 16, the robotic arm 20 places the first gemstone 22a on the plate 54a. In FIG. 17, the robotic arm 20 uses the hook element 51 to replace the cover 52a, covering the plate 54a and the first gemstone 22a. The first gemstone imaging device 12a (FIG. 2) then proceeds to perform its analysis, at least identifying the gemstone 22a by means of finding and storing an identification indicator, such as a number or set of alphanumeric characters, etched into the surface of the gemstone. While the first gemstone imaging device 12a (FIG. 2) analyzes the first gemstone 22a, the robotic arm 20 selects a second gemstone 22b from the initial repository 32, moves the second gemstone 22b to the cleaning station 40 to be cleaned in the manner described above, and then places the gemstone on a plate 54b of the second gemstone imaging device 12b, as shown in FIG. 18. In FIG. 18, a cover 52b has already been removed, at least partially, from the plate 54b. In FIG. 19, the robotic arm 20 uses the hook element 51 to replace the cover 52b, covering the plate 54b and the second gemstone 22b. The second gemstone imaging device 12b (FIG. 2) then proceeds to view and identify the second gemstone 22b. In certain embodiments, the system 10 further stores the information obtained from the analysis. In certain embodiments the gemstone imaging devices may also conduct a light return analysis. While the second gemstone imaging device 12b (FIG. 2) analyzes the second gemstone 22b, the robotic arm 20 returns to the first gemstone imaging station 50a, sets aside the cover 52a, and removes the gemstone 22a, as shown in FIG. 20.
In embodiments where the system 10 includes additional processing stations, the robotic arm 20 will additionally move the first gemstone 22a to each additional processing station for further analysis. FIG. 21 shows the robotic arm 20 placing the first gemstone 22a onto the scale 70, depicted schematically. The scale 70 measures the weight of the first gemstone 22a. In certain embodiments, the system 10 further stores the measured weight. FIG. 22 shows the robotic arm 20 placing the first gemstone 22a onto the gemstone color analyzer 80, again depicted schematically. The gemstone color analyzer 80 assigns a color grade to the first gemstone 22a. In certain embodiments, the system 10 further stores the assigned color grade. FIG. 23 shows the robotic arm 20 placing the first gemstone 22a onto the gemstone clarity analyzer 90, again depicted schematically. The gemstone clarity analyzer assigns a clarity grade to the first gemstone 22a. In certain embodiments, the system 10 further stores the assigned clarity grade. FIG. 24 shows the robotic arm 20 placing the first gemstone 22a onto the gemstone origin analyzer 100, again depicted schematically. The gemstone origin analyzer 100 determines whether the first gemstone 22a is a natural or a man-made stone. In certain embodiments, the system 10 further stores the determination.
Finally, once the first gemstone 22a has been cleaned and analyzed at each desired processing station, the robotic arm 20 places the first gemstone 22a at a particular location on the holding plate 60, as shown in FIG. 25. In certain embodiments, any information stored by the system 10 in relation to the first gemstone 22a is then associated with the particular location on the holding plate 60 where that first gemstone is placed.
The second gemstone 22b is then taken to any desired additional processing stations and placed at a second particular location on the holding plate 60. The above process is further repeated for each of a plurality of the remaining gemstones 22 located in the initial repository 32. When it is desired to remove a particular gemstone from the system 10, the operator communicates to the system 10 an input associated with a particular location on the holding plate 60. For example, in certain embodiments, the operator could input a code into a touchscreen, key pad, bar code scanner, or other input mechanism capable of receiving a form of code input, the input corresponding to the particular gemstone, which the system knows is at a particular location on the holding plate 60. The robotic arm 20 then selects the particular gemstone from the corresponding particular location on the holding plate 60 and delivers the particular gemstone to the operator.
Although the invention has been herein described in what is perceived to be the most practical and preferred embodiments, it is to be understood that the invention is not intended to be limited to the specific embodiments set forth above. Rather, it is recognized that modifications may be made by one of skill in the art of the invention without departing from the spirit or intent of the invention and, therefore, the invention is to be taken as including all reasonable equivalents to the subject matter of the appended claims and the description of the invention herein.
