For those skilled in the art, the specific meanings of the above terms in the embodiments of the present application can be understood according to the specific circumstances.

[0040] In order to reduce the cost of production and manufacturing, the present application no longer uses the traditional way of inlaying diamonds or gems to enhance the light and shadow effect of jewelry, but considers that the surface of the precious metal substrate itself is processed in a special way, so that it can present a good light and shadow effect under light irradiation, and ensure the beauty of the jewelry.

[0041] Based on this, through research and practice, the present application processes a plurality of light-reflecting portions on the surface of the precious metal substrate, the light-reflecting portions comprising a plurality of circular ring grooves, so as to reflect light in different directions by the surface of the circular ring grooves, so that the jewelry made of the precious metal substrate presents a good light and shadow effect, and such a way does not need to inlay diamonds or gems on the precious metal substrate, which can effectively save the processing and manufacturing cost of the jewelry and improve the product competitiveness.

[0042] According to one aspect of the embodiments of the present application, a kind of jewelry is provided, please refer to Figure 1 And Figure 2 , Figure 1 The front structure of the jewelry provided by the embodiments of the present application is shown in Figure 2 The cross-sectional structure along A-A is shown in Figure 1 As shown in the figure, the jewelry 100 comprises a precious metal substrate 110, at least one side of the precious metal substrate 110 is provided with a plurality of light-reflecting portions 111, the light-reflecting portions 111 comprise a plurality of circular ring grooves 112, the plurality of circular ring grooves 112 in each light-reflecting portion 111 are concentrically arranged, that is, the plurality of circular ring grooves 112 are concentric circles.

[0043] The precious metal base 110 can be gold, platinum, silver, etc. The precious metal base 110 can be a circular sheet structure as shown in Figure 1 and Figure 2 , or a circular column, a square sheet, a square block, a circular ring, etc. The specific shape can be set according to the type of jewelry or other requirements, which is not limited here.

[0044] The light-reflecting part 111 refers to a set of multiple concentric circular grooves 112. The surface of the circular grooves 112 can reflect light to make the surface of the precious metal base 110 present a good light and shadow effect.

[0045] In order to better understand and show the real structure of the light-reflecting part 111, please refer to the picture of the precious metal base 110 under the electron microscope as shown in Figures 3 to 5 , from which it can be clearly seen that each light-reflecting part 111 has multiple concentric circular grooves 112.

[0046] For specific light and shadow effects, please refer to Figures 6 to 9 , which shows the light and shadow effects of different shapes of precious metal base 110 under the irradiation of a surface light source. Due to the existence of the circular grooves 112 in the light-reflecting part 111, the surface of the precious metal base 110 is uneven, and the surface of each circular groove 112 at different positions in a circle is also different. These factors make the surface of the precious metal base 110 present a light and shadow effect under the irradiation of sunlight or a surface light source, and the whole jewelry 100 presents a three-dimensional light and shadow effect with better aesthetics.

[0047] The jewelry 100 can be a pendant as shown in Figure 6 or Figure 7 , or a ring as shown in Figure 8 or Figure 9 . Of course, in other embodiments, the jewelry 100 can also be a bracelet, a necklace, an earring, etc. The specific shape is not limited here.

[0048] Please refer to Figures 10 to 12 , which shows the light and shadow effects of different shapes of precious metal base 110 under the irradiation of a yellow point light source under an electron microscope, Figure 10 and Figure 11 , Figure 12The image shows the light and shadow effects of the precious metal substrate 110 under a normal lens. As shown, similarly, because the surface of the precious metal substrate 110 is uneven and the surface orientation of each position on each annular groove 112 is different, when the precious metal substrate 110 is illuminated by a point light source, the areas on its surface illuminated by more light along the optical axis of the point light source appear as bright spots, while the remaining areas appear as elongated fan-shaped spots spreading outward from the bright spots. These elongated fan-shaped spots gradually darken and become thinner from the position closer to the bright spots to the position further away. This light and shadow effect makes the surface of the jewelry 100 appear as if light is converging inward from the bright spots around the edges, creating a visually appealing light and shadow effect.

[0049] In addition, with Figure 10 For example, in Figure 10 Based on the state shown, when the relative position between the precious metal substrate 110 and the point light source is continuously adjusted and the precious metal substrate 110 is observed simultaneously, the position of the bright spot on the precious metal substrate 110 will also change accordingly, presenting a "light chasing" effect, that is, the bright spot will chase the light source, so that the jewelry 100 presents a good dynamic light and shadow effect.

[0050] In order to extend the lighting effect all the way to the edge of the precious metal substrate 110, such as Figure 1 and Figures 6-9 As shown, the annular grooves 112 in the reflective portion 111 located in the middle region of the surface of the precious metal substrate 110 are all complete annular rings, while the annular grooves 112 in the reflective portion 111 located in the edge region of the surface of the precious metal substrate 110 are at least partially arc-shaped. That is, not all grooves in the reflective portion 111 in the edge region are complete annular grooves 112; some grooves or all of the grooves do not form a complete ring. Figure 1 The part that does not form a complete circle is marked as an arc-shaped groove 113. The purpose of this design is to enable the reflective part 111 to cover the edge of the surface of the precious metal substrate 110, so as to ensure that the edge can also present the corresponding light and shadow effect.

[0051] Furthermore, to make the light and shadow distribution on the surface of the jewelry 100 dense and regular, and to improve the light and shadow effect, such as... Figures 3 to 5 as well as Figure 13 As shown, the edges of all adjacent reflective portions 111 are adjacent to each other. Specifically, a plurality of reflective portions 111 fill at least one entire surface of the noble metal substrate 110.

[0052] Specifically, if the light-reflecting part 111 of the middle area only includes a plurality of complete annular grooves 112, there will be a certain gap between the outermost annular grooves 112 of different light-reflecting parts 111, which makes several light-reflecting parts 111 unable to cover the entire surface of the precious metal base 110.

[0053] Therefore, in addition to the annular grooves 112 or the arc grooves 113, the outermost position of the light-reflecting part 111 also includes some smaller connecting grooves 114, which can be arc-shaped or strip-shaped. Adjacent light-reflecting parts 111 are connected to each other through the outermost annular grooves 112 or arc grooves 113 and the connecting grooves 114 at the outer edge, so that several light-reflecting parts 111 fill the entire surface of the precious metal base 110. After filling, as shown in Figures 10 to 12 , the light and shadow effect on the surface of the precious metal base 110 is regularly distributed, and the light change is uniform and smooth, and the overall light and shadow effect is good.

[0054] As shown in Figure 2 , the surface of the precious metal base 110 provided with the light-reflecting part 111 can be concave, which has a better light collecting effect and can make the light and shadow effect on the surface of the precious metal base 110 more intense. Of course, in other embodiments, the surface of the precious metal base 110 provided with the light-reflecting part 111 can also be flat.

[0055] Similarly, as shown in Figure 2 , the plurality of annular grooves 112 in each light-reflecting part 111 can be concave from the outermost to the innermost, which can make each light-reflecting part 111 have a certain light collecting effect, and the surface of the plurality of annular grooves 112 in each light-reflecting part 111 has a more intense contrast between light and shadow, and the light and shadow effect on the surface of the precious metal base 110 is better and more obvious. Of course, in other embodiments, the plurality of annular grooves 112 in each light-reflecting part 111 can also be distributed in a flat state.

[0056] Considering that after a long time of wearing, if the light-reflecting part 111 on the surface of the precious metal base 110 is worn or the like, it may cause the light and shadow effect to weaken, thereby affecting the subsequent aesthetics of the jewelry 100. For this purpose, please refer to Figures 14 to 17 , Figure 14 shows the front structure of the jewelry 100 provided by another embodiment of the present application, Figures 15 to 17 shows the structure of the jewelry 100 provided by several embodiments of the present application. As shown in the figure, the jewelry 100 can also include a frame 120, which is wrapped around the edge of the precious metal base 110. The frame 120 can be made of the same precious metal material as the precious metal base 110, or other metals, alloys or plastics with better hardness and wear resistance.

[0057] By surrounding the frame 120 around the edge of the noble metal base 110, the edge of the noble metal base 110 can be protected from being damaged due to collision, friction, etc.

[0058] In order to further improve the appearance, as shown in Figure 15 and Figure 16 , the frame 120 can be provided with a first decorative part 121, which can be a protrusion with a specific shape as shown in Figure 15 , or a hollow structure as shown in Figure 16 , and of course can also be a plane or a three-dimensional pattern, etc., which is not limited here.

[0059] As shown in Figure 17 , the surface of the noble metal base 110 can also be provided with a second decorative part 122 by welding or other methods, which can be a protrusion with a specific shape, a plane or a three-dimensional pattern, etc.

[0060] It can be understood that in the specific implementation process, only the first decorative part 121 can be provided on the frame 120, or only the second decorative part 122 can be provided on the noble metal base 110, and of course the first decorative part 121 and the second decorative part 122 can be provided on both of them at the same time, and the decorative parts at different positions can be the same or different.

[0061] According to another aspect of the embodiment of the present application, a jewelry processing method is provided, please refer to Figure 18 , the flow chart of the jewelry processing method provided by the embodiment of the present application is shown, as shown in the figure, the jewelry processing method comprises the following steps:

[0062] Step 210: placing the noble metal base on the clamp of the processing equipment.

[0063] In this step, the noble metal base can be a preliminarily formed sheet, column, block, ring, etc., and its processing surface can be a flat plane or a smooth curved surface, and the processing equipment can be a numerical control machine tool.

[0064] Step 230: processing a plurality of arrayed light-reflecting parts on the surface of the noble metal base by the processing equipment, wherein the light-reflecting part comprises a plurality of circular ring grooves, and the plurality of circular ring grooves in each light-reflecting part are concentrically arranged.

[0065] The noble metal base 110 with a plurality of light-reflecting parts 111 processed in this step is shown in Figure 1 .

[0066] Step 250: obtaining the jewelry.

[0067] The jewelry manufacturing method provided in the embodiments of the present application comprises the following steps: a processing device is used to control a cutter head thereof to move to a plurality of preset coordinates on the surface of a precious metal base body in sequence, and after the cutter head moves to each preset coordinate, the cutter head is first controlled to descend and rotate synchronously, and then the cutter head is controlled to ascend and reset, so as to process a plurality of light-reflecting parts arranged in an array on the surface of the precious metal base body. Figures 6 to 9 The jewelry manufacturing method provided in the embodiments of the present application comprises the following steps: a processing device is used to control a cutter head thereof to move to a plurality of preset coordinates on the surface of a precious metal base body in sequence, and after the cutter head moves to each preset coordinate, the cutter head is first controlled to descend and rotate synchronously, and then the cutter head is controlled to ascend and reset, so as to process a plurality of light-reflecting parts arranged in an array on the surface of the precious metal base body. Figures 10 to 12 The jewelry manufacturing method provided in the embodiments of the present application comprises the following steps: a processing device is used to control a cutter head thereof to move to a plurality of preset coordinates on the surface of a precious metal base body in sequence, and after the cutter head moves to each preset coordinate, the cutter head is first controlled to descend and rotate synchronously, and then the cutter head is controlled to ascend and reset, so as to process a plurality of light-reflecting parts arranged in an array on the surface of the precious metal base body.

[0068] The step 230 can specifically comprise the following steps:

[0069] The step 231 comprises the following steps: the processing device is used to control the cutter head thereof to move to the plurality of preset coordinates in sequence, and after the cutter head moves to each preset coordinate, the cutter head is first controlled to descend and rotate synchronously, and then the cutter head is controlled to ascend and reset, so as to process the plurality of light-reflecting parts arranged in an array on the surface of the precious metal base body.

[0070] The cutter head 300 is used to process the light-reflecting parts 111 arranged in an array on the surface of the precious metal base body. Figure 19 The cutter head 300 is used to process the light-reflecting parts 111 arranged in an array on the surface of the precious metal base body. Figure 1 The cutter head 300 is used to process the light-reflecting parts 111 arranged in an array on the surface of the precious metal base body. Figure 2 The cutter head 300 is used to process the light-reflecting parts 111 arranged in an array on the surface of the precious metal base body. The cutter head 300 is used to process the light-reflecting parts 111 arranged in an array on the surface of the precious metal base body.

[0071] The cutter head 300 is used to process the light-reflecting parts 111 arranged in an array on the surface of the precious metal base body. The cutter head 300 is used to process the light-reflecting parts 111 arranged in an array on the surface of the precious metal base body.

[0072] The cutter head 300 adopts the serrated blade 310, and the machining is performed by rotating the cutter head, which can effectively ensure the concentricity of the multiple annular grooves in the plurality of light-reflecting parts, and further ensure the regularity of the light and shade distribution and brightness change in the light and shade effect presented by the precious metal substrate machined through the plurality of light-reflecting parts.

[0073] It should be noted that when the annular groove is machined by rotating the cutter head, in order to ensure that the annular groove is formed in the entire machining area and ensure the light and shade effect, the feed distance of the cutter head 300 is set to be relatively large, so that the entire blade can be in full contact with the precious metal substrate and cut, thereby machining the multiple annular grooves arranged closely. However, it is found in practice that when the feed distance of the cutter head 300 is too large, the inner circle is blocked by the outer circle, which causes problems such as chip removal and heat dissipation difficulty, and further causes problems such as chip jamming and cutter head overheating, thereby affecting the machining precision and success rate.

[0074] To this end, the present application considers using multiple cutting and gradually increasing the feed distance to overcome the above problems. Specifically, the above step 231 is repeatedly executed multiple times, and the feed distance of the cutter head 300 is gradually increased.

[0075] Suppose the cutting depth is 3 mm, and the feed amount of each time is 0.2 mm more than the previous time, and the specific process is as follows:

[0076] First, control the cutter head 300 to move to the first preset coordinate, then control the cutter head 300 to descend and rotate synchronously, after the cutter head 300 descends to the first height of contact with the surface of the precious metal substrate, continue to descend by 0.2 mm (this is the feed distance of the first machining), to preliminarily machine the first light-reflecting part, then the cutter head 300 is raised and reset and moved to the next preset coordinate, the cutter head 300 is lowered again and rotated synchronously, after contacting the surface of the precious metal substrate, continue to descend by 0.2 mm, to preliminarily machine the next light-reflecting part, and so on, until all the light-reflecting parts are preliminarily machined.

[0077] Then control the cutter head 300 to move to the first preset coordinate, then control the cutter head 300 to descend and rotate synchronously, after the cutter head 300 descends to the first height, continue to descend by 0.2 mm+0.2 mm=0.4 mm (this is the feed distance of the second machining), to machine the first light-reflecting part for the second time, then the cutter head 300 is raised and reset and moved to the next preset coordinate, the cutter head 300 is lowered again and rotated synchronously, after reaching the first height, continue to descend by 0.4 mm, to machine the next light-reflecting part for the second time, and so on, until all the light-reflecting parts are machined for the second time.

[0078] According to the steps described in the above two paragraphs, until each light-reflecting part is machined for 15 times, and the total cutting depth of 3 mm is reached, the machining is completed, and the jewelry is obtained.

[0079] It can be understood that the above specific values of the cutting depth, the feeding amount and the processing times are only exemplary and do not limit the specific values of the corresponding parameters.

[0080] In this way, the feeding distance is increased gradually, so that the cutting depth of each cutting is not too large, thereby preventing the problems of difficult chip removal and heat dissipation of the inner ring position.

[0081] In the processing, the straight line distance between the two adjacent preset coordinates can be set to be equal to the rotating diameter of the tool head. The two adjacent preset coordinates mentioned herein are not adjacent in the control sequence, but adjacent in the spatial sense, that is, not referring to the two preset coordinates reached by the tool head 300 in two consecutive movements, but referring to the two preset coordinates adjacent to each other in the movement plane of the tool head 300.

[0082] Therefore, the straight line distance between the two adjacent preset coordinates is equal to the rotating diameter of the tool head 300, which means that the outer circles of any two adjacent light reflection parts of the processed light reflection parts are tangent to each other, as shown in FIG. 6. Figure 1 In this way, the light reflection parts 111 are arranged uniformly and closely on the surface of the precious metal substrate 110, and the tightness and consistency of the light and shadow effect of the surface of the precious metal substrate 110 are ensured.

[0083] Of course, the straight line distance between the two adjacent preset coordinates can also be set to be less than the rotating diameter of the tool head 300, so that the two adjacent light reflection parts will overlap partially, and accordingly, in the actual processing, the light reflection part processed later will cut off part of the light reflection part processed earlier, and finally present the effect as shown in FIG. 7. Figures 3 to 5 and FIG. 8. Figure 13 In this way, the jewelry processed in this way includes the intermediate multiple-coil complete annular grooves 112, and the edge position also has some arc-shaped connection grooves 114, the adjacent light reflection parts 111 are closely adjacent through the outermost complete annular groove 112 and the connection grooves 114, the entire surface of the precious metal substrate 110 is filled with the light reflection parts 111, and the light and shadow effect of the surface of the precious metal substrate 110 is distributed regularly as shown in FIG. 9. Figures 10 to 12
