Description

Technical Field

[0001] This utility model relates to the technical field of gemstone grinding and polishing equipment, specifically to a turning device and an automatic gemstone feeding device for gemstone processing. Background Technology

[0002] Gemstones, used as decorative items, are loved and welcomed by people from all walks of life, ranging from jewelry (rings, bracelets, necklaces, etc.), pendants, and earrings to home decorations. To enhance the appearance of gemstones, their surfaces need to be polished to improve their aesthetic appeal and ornamental value.

[0003] In the grinding and polishing process of sheet-like gemstones (such as jade slices and crystal slices), the traditional method of grinding and polishing individual sheet-like structures manually is slow, labor-intensive, and costly, and cannot meet the needs of batch processing. To address these issues, a method was invented that uses a jig to clamp multiple sheet-like gemstones and then grind and polish the same side of multiple sheet-like gemstones simultaneously, improving efficiency. However, this method has the following problems: after grinding and polishing, each sheet-like gemstone needs to be manually flipped over one by one. This method is labor-intensive and costly. Manual flipping can easily cause positional deviations, and hand operation can easily introduce impurities, resulting in the grinding surface not being parallel to the equipment reference surface (tilt angle error >3°), requiring repeated calibration and affecting processing efficiency.

[0019] For examples, see the appendix. Figures 1-4A gemstone turning device 1 is installed on a workbench. The turning device 1 is used for turning sheet-like gemstones. The turning device 1 includes a platform 2 and two opposing pushing mechanisms 7. A turning mechanism 8 for turning gemstone materials is provided between the two pushing mechanisms. A channel 6 is provided between one of the pushing mechanisms 7 and the turning mechanism 8. The platform 2 has a first support 3, a second support 4, and a third support 5 arranged sequentially. The two pushing mechanisms 7 are respectively mounted on the first support 3 and the third support 5. The turning mechanism 8 is... On the second support, the channel 6 is disposed between the first support 3 and the second support 4. The channel 6 is provided with a platform 60 for placing gemstone materials. The platform 60 is disposed on a moving mechanism, which can be one of a conveyor belt or a pusher slide module. The pusher mechanism 7 on the first support 3 is used to push the gemstone materials from the platform 60 into the flipping mechanism 8. The flipping mechanism 8 is used to perform a flipping action on the gemstone materials. The pusher mechanism 7 on the third support 5 is used to push the gemstone materials in the flipping mechanism 8 away from the flipping mechanism 8 onto the platform 60.

[0020] Each of the pushing mechanisms 7 is equipped with a pusher block 712b. The moving direction of the platform 60 is perpendicular to the pushing direction of the pusher block 712b of the pushing mechanism 7. The flipping mechanism 8 is equipped with a channel 810 for pushing or pushing gemstone materials. The channel 810 is oriented in the same direction as the movement of the pusher block 712b, and the channel 810 is connected to the output plane of the platform 60. The output plane is the plane on which the gemstone material moves or is pushed out towards the channel 810. Both ends of the channel 810 are provided with openings. The size of the openings is larger than the size of the pusher block 712b, thereby ensuring the insertion of the pusher block 712b. The channel 810 is a strip-shaped channel, and the pusher block 712b is a strip-shaped pusher block. The upper and lower edges of the openings are provided with inclined surfaces or arc surfaces, which serve as guides.

One end of the slide rail 71 has a mounting block 710, and the other end has a stabilizing block 711. The first driving component 70 is mounted and fixed on the mounting block 710. The slide rail 71 has a slidably connected slide table 712, which is fixedly connected to the driving end of the first driving component. The slide table 712 is provided with a fixed seat 712a, and the push block 712b is fixed on the fixed seat 712a. The first driving member 70 is a cylinder. The pushing mechanism 7 is used to realize the automatic pushing action, thereby realizing the movement of the gemstone material towards the flipping mechanism 8 or the push of the flipped gemstone material from the flipping mechanism 8, improving automation efficiency, increasing cycle efficiency by 50%, and improving subsequent processing efficiency. The first driving member 70 is provided with a sensor, which is used to detect the extension amount of the first driving member 70, thereby ensuring the pushing stroke of the gemstone material.

[0022] The third bracket 5 is also provided with a fourth bracket 50, and the fourth bracket 50 is disposed above the slide rail 71. The flipping mechanism 8 includes a second driving member 500 and a mounting base 40. The second driving member 500 is fixed vertically on the fourth bracket 50 by means of a threaded connection. The driving end of the second driving member 500 is a rotating shaft. The second driving member 500 can be a rotary cylinder or a servo motor. The second driving member 500 is used to provide a driving source. The mounting base 40 is mounted on the second bracket 4. The mounting base 40 has bearings 400 arranged opposite each other, with a gap between the two bearings 400 to accommodate the synchronous pulley 310a or gear. A rotating shaft 80 is provided between the two bearings 400. The rotating shaft 80 has through holes 800, and each through hole 800 has a placement platform 81. The placement platform 81 and the through hole 800 can be an integrally formed structure or a detachable connection structure. The placement platform 81 has a channel 810 for placing gemstone materials. The flipping mechanism 8 is used to achieve rotation, thereby flipping the gemstone materials in the channel 810, realizing automatic flipping, saving manual operation time and cost, and improving the efficiency of subsequent polishing and processing. The clearance fit tolerance between the rotating shaft 80 and the bearing 400 is ≤0.01mm, ensuring that the 180° flipping angle error is ≤±0.1°.

[0023] The linkage component 301 includes two synchronous pulleys 310a, which are respectively disposed at the driving end of the second driving member 500 and sleeved on the rotating shaft 80; a belt 310b is sleeved between the two synchronous pulleys 310a to form a linkage connection, and the belt 310b is a synchronous toothed belt. The linkage component 301 is used to control the rotation of the rotating shaft 80.

[0024] In another embodiment, the linkage component 301 includes two gears, which are respectively disposed at the driving end of the second driving member 500 and sleeved on the rotating shaft 80, and the two gears mesh with each other to form an engagement connection.

[0025] See appendix Figure 2 The mounting base 40 is provided with a support block 401. The slide rail 71 on the first bracket 3 extends to the support block 401 of the second bracket 4, and the stabilizing block 711 is fixed on the support block 401. The support block 401 is used to support the end of the slide rail 71 on the first bracket 3 to ensure that the slide rail 71 is placed horizontally, thereby ensuring the efficiency and smoothness of the subsequent push block 712b pushing the gemstone material.

[0026] See appendix Figure 4 The stabilizing block 711 is provided with a first slot 711a for the push block 712b to push out or retract; the push block 712b has a strip structure, and the stabilizing block 711 is used to ensure the stable placement of the push block 712b.

[0027] The first slot 711a and the channel 810 are both set on the same horizontal axis, thereby ensuring the stability of the gemstone material pushing or pushing action and ensuring that the gemstone material pushing path is not deviated; the surface of the platform 60 and the inner wall of the channel 810 are provided with an adhesive oil film, which is used to ensure that the gemstone material is attached to the surface of the platform 60 or the inner surface of the channel 810, so that the gemstone material is on the surface of the platform 60 after flipping.

[0028] See appendix Figure 5 An automatic gemstone feeding device 10 includes the aforementioned turning device 1 for gemstone processing.

[0029] The working principle of this utility model is as follows: After the gemstone material placed on the feeding mechanism is polished on the first side, it is pushed between the first support 3 and the second support 4. After it is in place, the pushing mechanism 7 on the first support 3 is activated, and the first driving member 70 controls the pushing block 712b to push the gemstone material towards the channel 810 of the rotating shaft 80. After it is pushed into place, the pushing mechanism 7 on the first support 3 is reset, and the second driving member 500 drives the rotating shaft 80 to rotate 180°, so that the gemstone material in the channel 810 is flipped 180°. After the flipping is completed, the pushing mechanism 7 on the third support 5 is activated, and the first driving member 70 on the third support 5 controls the pushing block 712b to move towards the channel 810. The pushing block 712b pushes the gemstone material in the channel 810 onto the feeding mechanism. After it is pushed into place, the pushing mechanism 7 is reset, and the entire flipping process is completed.

[0030] This invention utilizes a flipping mechanism to achieve rotation, simultaneously flipping multiple gemstone materials within the channel. This automatic flipping saves manual operation time and costs, and improves subsequent polishing efficiency. A pushing mechanism automatically pushes the gemstone materials towards the flipping mechanism or pushes them out after flipping, further enhancing automation and subsequent processing efficiency.
