Specific implementation mode
[0024] Before and after different jewelry rough stones are processed, it is necessary to classify and judge the suitable cutting shapes and transparent color conditions of the jewelry rough stones, and it is also necessary to judge and detect the internal defects, surface defects, color spots, and color patches of different rough stones. The existing technology generally screens by manual labor, with low sorting efficiency, and it is easy for workers to make sorting errors after working for a long time.
[0025] As Figures 1-6 shown, the device includes a workbench 1. A driving motor 11 is installed on the top of the workbench 1. A guiding glass disk 2 is installed on the top of the driving motor 11. A feeding hole 21 is opened on the top of the guiding glass disk 2. The top of the guiding glass disk 2 can be selected to open the feeding hole 21 or replace it with a flat glass according to the material situation. A blanking sleeve 3 is arranged on the top of the workbench 1. A discharge port 31 is opened at the bottom of the blanking sleeve 3. A detection component 4 is installed on the top of the workbench 1. The detection component 4 is used to take pictures and detect the jewelry rough stones on the guiding glass disk 2. A classification component 5 is arranged on the top of the workbench 1. The classification component 5 is used to classify and screen the detected jewelry rough stones;
[0026] First, considering the problem of how to place the jewelry rough stones on the guiding glass disk 2, show Figure 3 and Figure 4 , there are multiple feeding holes 21. The multiple feeding holes 21 are arranged in a circumferential array on the top of the guiding glass disk 2. The blanking sleeve 3 is arranged on the top of the feeding hole 21 and is used to drop the jewelry rough stones into the feeding hole 21.
[0027] The improvement of this embodiment lies in: driving the feeding glass disk 2 to rotate by the driving motor 11, placing the loose gemstones into the vibrating disk, so that the loose gemstones can fall from the top of the blanking sleeve 3 through the conveying plate, and the loose gemstones fall into the feeding hole 21 opened at the top of the feeding glass disk 2 at the bottom of the blanking sleeve 3. The feeding glass disk 2 rotates, driving the gemstones in the feeding hole 21 to rotate. The discharge port 31 opened at the bottom of the blanking sleeve 3 allows the loose gemstones to rotate out of the blanking sleeve 3, so that the loose gemstones can rotate on the feeding glass disk 2. After passing through the detection component 4, the loose gemstones are photographed and detected. After the detection is completed, the loose gemstones of different qualities are screened by the classification component 5.
[0028] It should be noted that the feeding glass disk 2 can be replaced with a flat glass disk without the feeding hole 21, which is suitable for the detection of different loose gemstones.
[0029] Secondly, considering the problem of how to detect the loose gemstones, present Figure 1 And Figure 5 , the specific structure of the detection component 4 is disclosed. The detection component 4 includes a support frame 401 fixedly installed on the top of the workbench 1. A high-definition camera 402 is installed on the outside of the support frame 401. The high-definition camera 402 is installed on the top of the feeding glass disk 2 and is used to photograph the loose gemstones in the feeding hole 21 at the top of the feeding glass disk 2.
[0030] There are two high-definition cameras 402. The two high-definition cameras 402 are symmetrically staggered at the top and bottom of the feeding glass disk 2, and can photograph the loose gemstones from the upper and lower directions. Multiple high-definition cameras 402 can also be installed according to the needs of gemstone detection, and different detection parts and angles can be set according to specific inspection requirements.
[0031] By arranging high-definition cameras 402 on both the top and bottom of the feeding glass disk 2, when the loose gemstones entering the feeding hole 21 pass through the two high-definition cameras 402, the two high-definition cameras 402 can respectively photograph the top and bottom of the loose gemstones. The photographed photo images are then transmitted to the computer system, and the computer system will analyze these images to identify the characteristics of the gemstone such as color, transparency, shape, and size. The structure and characteristics of the product can be compared with the known gemstone quality characteristics in the database, and the system can automatically judge the color and quality of the gemstone and classify it, so as to detect the loose gemstones.
[0032] It should be noted that there are various types of jewelry data in the computer system database, such as natural gemstones: diamonds, rubies, sapphires, emeralds, cat's-eye stones (i.e., chrysoberyl), tourmalines, garnets, aquamarines, amethysts, citrines, peridots, tanzanites, topazes, andalusites, moonstones, obsidians, agates, jaspers, pearls, ambers; natural jade: Hetian jade, jadeite (including Burmese jadeite and Guatemalan jadeite), Dushan jade, Xiu jade, Lantian jade, turquoise, lapis lazuli, malachite, Shoushan stone, coral jade, rice yellow jade, ivory jade, honey wax yellow jade, Xixia jade, purple robe jade, crystal, Kawashi, siliconized wood, tiger's eye stone, gold star stone, fluorite; and various unprocessed raw materials, semi-processed blanks of natural diamonds, natural gemstones, synthetic gemstones, cultivated gemstones, cultivated diamonds, etc., as well as classified synthetic cubic zirconia and alumina products in the form of loose stones produced and processed in various regions of China. This device can detect the above-mentioned loose stone jewelry.
[0033] It should also be noted that multiple high-definition cameras 402 can be added outside the guiding glass disk 2 according to the specific detection requirements of different loose stone jewelry to inspect specific parts, positions of the loose stone jewelry or to meet the detection requirements of special requirements. The high-definition cameras 402 can take clear pictures of the loose stone jewelry, which is convenient for the computer to compare with the pictures in the database for detection. The high-definition cameras 402 are prior art, and their working principles are common knowledge for those skilled in the art, so they will not be elaborated here.
[0034] Finally, considering the problem of how to classify and screen the loose stone jewelry, Figure 5 and Figure 6 , the specific structure of the classification component 5 is disclosed. The classification component 5 includes a first support column 501 fixedly installed on the top of the workbench 1. The top of the first support column 501 is fixedly installed with a first placement plate 502. A plurality of material receiving blocks 503 are installed on one side of the first placement plate 502 close to the guiding glass disk 2. A second support column 504 is fixedly installed on the top of the first placement plate 502. The top of the second support column 504 is fixedly installed with a second placement plate 505. A plurality of connecting rods 506 are installed on the top of the second placement plate 505. High-frequency air valves 507 are fixedly installed at the bottoms of the plurality of connecting rods 506.
[0035] A plurality of material receiving blocks 503 are all arranged outside the guiding glass disk 2. A plurality of high-frequency air valves 507 are all arranged on the top of the discharge hole 21. The high-frequency air valves 507 can blow the detected loose stone jewelry into the corresponding material receiving blocks 503.
[0036] The improvement of this embodiment lies in that the photos taken by the high-definition camera 402 are transmitted into the computer system to determine the quality of the loose gemstones. When the loose gemstone rotates to the high-frequency air valve 507, the computer system controls the high-frequency air valve 507 corresponding to the quality of the loose gemstone to blow, so that the loose gemstone enters the corresponding receiving block 503. A built-in receiving box is installed at the bottom of the receiving block 503 or it is connected to an external receiving box through a pipeline to pick up and store the sorted loose gemstones, achieving the effect of screening the loose gemstones.
[0037] It should be noted that the high-frequency air valve 507 is a kind of air valve device that can quickly realize the on-off control of gas and has a relatively high action frequency. The internal circuit structure of the high-frequency air valve 507 is the prior art, and its working principle is common knowledge for those skilled in the art, so it will not be elaborated here.
[0038] In summary, the working principle of this solution is as follows:
[0039] The driving motor 11 drives the guiding glass disk 2 to rotate, and the loose gemstones are placed in the vibrating disk, so that the loose gemstones can fall from the top of the feeding sleeve 3 through the conveying plate of the vibrating disk, and the loose gemstones fall into the feeding hole 21 opened at the top of the guiding glass disk 2 at the bottom of the feeding sleeve 3. The guiding glass disk 2 rotates, driving the gemstones in the feeding hole 21 to rotate. The discharge port 31 opened at the bottom of the feeding sleeve 3 allows the loose gemstones to rotate out of the feeding sleeve 3, so that the loose gemstones can rotate on the guiding glass bottle disk;
[0040] When the loose gemstones in the feeding hole 21 rotate past the two high-definition cameras 402, the two high-definition cameras 402 can respectively take pictures of the top and bottom of the loose gemstones. The taken photo images are then transmitted to the computer system, and the computer system will analyze these images to judge the quality of the loose gemstones. Then, the computer system controls the high-frequency air valve 507 corresponding to the quality of the loose gemstone to blow, so that the loose gemstone enters the corresponding receiving block 503, achieving the effect of screening the loose gemstones.
[0041] The above shows and describes the basic principle, main features and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited by the above embodiments.
