Description

Technical Field

[0001] The invention relates to the technical field of jewelry processing, in particular to an automatic stone setting machine for ring-shaped jewelry. Background Art

[0002] By inlaying gemstones on jewelry, the decorativeness and aesthetics of jewelry can be effectively improved. Claw setting is a common and relatively simple gemstone inlay process, and the specific method is to fasten the gemstone on the bracket with a metal claw. In the prior art, the claw setting of gemstones is generally operated manually, by clamping the gemstone with tweezers, placing it in the metal claw, and then clamping the metal claw with tweezers to fix the gemstone. The efficiency of this method is very low, and the inlay quality is uneven, and the gemstone is prone to tilting or loosening. Some technologies use machines to assist in inlaying. For example, when performing a gemstone claw setting operation on a ring, first manually place the ring on the positioning fixture of the machine, then adjust the fixture to tighten the ring, then use tweezers or a pneumatic suction nozzle to take out the gemstone, and place the gemstone in the metal claw, then manually operate the machine, use the fork head to clamp the metal claw to fix the gemstone, and finally rotate the fixture to switch to the next gemstone inlay position. Although the machine can improve a certain efficiency compared to pure manual operation, due to the low degree of automation of the machine, a large amount of manual operation is still required, so the effect of improving the inlay efficiency is limited.

[0027] Working principle: When using the present invention, the feeding assembly 2 on the machine 1 is used to provide annular ornaments for the stone setting assembly 3, and the material taking assembly 4 is used to transport the gems on the feeding rack 11 to the stone setting assembly 3, and the stone setting assembly 3 fixes the annular ornaments and sets the gems. Specifically, the first motor 219 on the bracket 21 is started, and the first motor 219 drives the first connecting shaft 220 to rotate a set angle, and the first connecting shaft 220 drives the push plate 213 through the threaded rod 22, and the push plate 213 moves forward one station, pushing the annular ornament placed on the support rod 210 to one station, so that the frontmost annular ornament is inserted between the two clamping claws 217, and under the elastic action of the spring 218, the clamping claw 217 automatically clamps the annular ornament The first cylinder 214 is then started to drive the first moving seat 215. The clamping claw 217 on the first moving seat 215 moves to one side of the flange 36, and the annular ornament is blocked by the flange 36. At this time, the second cylinder 311 is started, and the second cylinder 311 is retracted, and the second connecting member 313 is driven by the first connecting member 312. The second connecting member 313 deflects on the second fixed block 314. The other end of the second connecting member 313 drives the second connecting shaft 38. The second connecting shaft 38 slides along the hollow shaft 33, and the tilting block 310 is driven to deflect in the first fixed seat 34 through the rotating member 39. The other end of the tilting block 310 lifts the supporting block 37, and the supporting block 37 slides outward along the through groove 35, thereby supporting the annular ornament;The first linear module 41, the second linear module 42 and the third linear module 43 are started, and the position of the fifth cylinder 44 is adjusted, so that the suction nozzle 46 on the fourth movable seat 45 is transferred to the top of the feeding rack 11 to suck the gemstone, and then the gemstone is transferred and placed in the metal claw of the ring-shaped ornament. At this time, the position of the fifth cylinder 44 is adjusted by the second linear module 42, and the first pressing head 47 is transferred to the top of the gemstone, and the fifth cylinder 44 is started. The fifth cylinder 44 drives the fourth movable seat 45 to press down, so that the first pressing head 47 pre-presses the gemstone in the center of the metal claw, and then the material picking component 4 is reset and the next material picking action is performed. The third cylinder 316 on the second fixed seat 315 extends, and the third fixed seat 317 drives the third fixed seat 317 to move the gemstone. The third movable seat 320 on the third fixed seat 318 moves accordingly, and the fork head 321 and the second pressing head 322 on the third movable seat 320 move to the setting position. At this time, the fourth cylinder 319 extends out, driving the third movable seat 320 to press down, and the second pressing head 322 is used to position the gemstone, and the fork head 321 forces the metal claws to close toward the center to clamp the gemstone, thereby completing the claw setting of the gemstone, and then the third cylinder 316 and the fourth cylinder 319 are reset in turn, the second motor 32 is started, and the divider 31 rotates one station, so that the hollow shaft 33 drives the first fixed seat 34 to rotate one station, and the support block 37 on the first fixed seat 34 rotates accordingly, thereby switching the annular ornament to the next gem setting position. After completing the gemstone inlay in all positions, the second cylinder 311 and the first cylinder 214 are reset in sequence. The second cylinder 311 extends to reset the support block 37, and the first cylinder 214 retracts to bring the annular ornament away from the support block 37 through the clamp 217. Since the annular ornament in this process is only pushed by the clamp 217, it will not be stuck in the clamp 217, but will fall onto the blanking inclined plate 222 through the discharge port 221 to realize automatic discharge. The clamp 217 is reset to the material taking position of the annular ornament, waiting for the next loading. Among them, if the position of the support rod 210 needs to be adjusted to adapt to annular ornaments of different specifications, the hollow screw 23 on the first fixed block 24 can be rotated, and the hollow screw 23 drives the first slider 27, and the first slider 27 is rotated. The second connecting rod 28 on a slider 27 drives the first connecting rod 25. The cross connecting rod structure formed by the first connecting rod 25 and the second connecting rod 28 can adjust the distance between the support rod 210 and the hollow screw 23. The sliding sleeve 26 is used to connect the first connecting rod 25 and the support rod 210. The fixed sleeve 29 is used to connect the second connecting rod 28 and the support rod 210. The second slider 211 cooperates with the sliding groove 212 to guide the support rod 210. The guide rod 216 is used to install the clamping claw 217. The divider 31 adopts the existing technology, and only the output shaft is replaced by the hollow shaft 33. Therefore, the specific principle of the divider 31 will not be repeated. The main parts of the two clamping claws 217 are two symmetrical semicircles, and the opening position is provided with a guiding round table surface. ;

[0028] It will be apparent to those skilled in the art that the invention is not limited to the details of the exemplary embodiments described above and that the invention can be implemented in other specific forms without departing from the spirit or essential features of the invention. Therefore, the embodiments should be considered exemplary and non-limiting in all respects, and the scope of the invention is defined by the appended claims rather than the foregoing description, and it is intended that all variations falling within the meaning and scope of the equivalent elements of the claims be included in the invention. Any reference numeral in a claim should not be considered as limiting the claim to which it relates.
