Detailed implementation manners

[0014] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0015] Please refer to Figures 1-8, an embodiment of the present invention is: a three-dimensional laser welding device applied to annular gold jewelry, including a base 1, a bracket 2 is fixedly connected to the top of the base 1, a three-dimensional welding machine 3 is fixedly connected to the top of the base 1, a dust-proof protection mechanism 4 is arranged on both sides of the bracket 2, a pushing mechanism 5 for part discharging is arranged on the top of the base 1, a bidirectional motor 6 is fixedly connected to the inner wall of the base 1, a sliding long plate 7 is slidably connected to the inner wall of the bracket 2, a first elastic telescopic rod 8 is fixedly connected to the top of the sliding long plate 7, a telescopic end of the first elastic telescopic rod 8 is fixedly connected to a bottom support 9. Before the device is started, the operator first places the annular gold jewelry to be welded on the top of the bottom support 9. The annular gold jewelry can be easily positioned and placed through the two bottom supports 9. After the operator finishes placing, the sliding long plate 7 needs to be pushed into the slot of the bracket 2. The movement of the sliding long plate 7 will drive the first elastic telescopic rod 8 to move, and the movement of the first elastic telescopic rod 8 will drive the bottom support 9 to move. At this time, the bottom support 9 can reach the welding area for subsequent laser welding. Through manual placement and positioning, the gold jewelry can be adjusted more flexibly, especially when facing complex or non-standard jewelry designs. The craftsman can manually adjust the position according to the actual situation to ensure the accuracy and perfect docking of the welding parts, which can improve the welding accuracy and welding efficiency. The output end of the bidirectional motor 6 is fixedly connected to a reciprocating lead screw 10, a limiting column 11 is fixedly connected to the inner wall of the base 1, the circumferential surface of the reciprocating lead screw 10 is movably connected to a moving plate 12, a hollow block 13 is fixedly connected to the inner wall of the moving plate 12, a second elastic telescopic rod 14 is fixedly connected to the inner wall of the hollow block 13, a telescopic end of the second elastic telescopic rod 14 is fixedly connected to a connecting block 15, the circumferential surface of the connecting block 15 is rotatably connected to a fixed block 16 through a torsion spring, the moving plate 12 is in contact with the base 1, and the moving plate 12 is slidably connected to the circumferential surface of the limiting column 11. When the gold jewelry on the top of the bottom support 9 reaches the welding area, the bidirectional motor 6 will be started, and the output end of the bidirectional motor 6 will drive the reciprocating lead screw 10 to rotate. The rotation of the reciprocating lead screw 10 will drive the moving plate 12 to rotate. However, at this time, the moving plate 12 will be limited by the limiting column 11. At this time, the moving plate 12 can only move horizontally through the reciprocating groove on the surface of the reciprocating lead screw 10. The movement of the moving plate 12 will drive the hollow block 13 to move, the movement of the hollow block 13 will drive the second elastic telescopic rod 14 to move, the movement of the second elastic telescopic rod 14 will drive the connecting block 15 to move, and the movement of the connecting block 15 will drive the fixed block 16 to move. After the fixed block 16 moves a certain distance, the fixed block 16 will fix the annular gold jewelry through its own inclined surface, ensuring that the gold jewelry cannot move during welding, improving the welding quality of the device, reducing welding errors, and being able to reduce welding costs.

[0016] The protection mechanism 4 includes a connecting column 401 and a dust-proof cover 402. The connecting column 401 is fixedly connected to the inner wall of the hollow block 13, and the dust-proof cover 402 is fixedly connected to the circumferential surface of the connecting column 401. When the device is started, the movement of the hollow block 13 will drive the connecting column 401 to move, and the connecting column 401 will drive the dust-proof cover 402 to move during the movement. At this time, after the two dust-proof covers 402 move a certain distance, the two dust-proof covers 402 can approach and fit each other. At this time, the dust-proof cover 402 can isolate the welding area of the device from the outside to a certain extent, avoid the welding area of the device from being polluted, ensure that during the welding of gold jewelry, external sundries and dust cannot contact it, avoid poor fusion of the welding parts, resulting in voids, pores or uneven seams, and ensure the welding quality. The protection mechanism 4 also includes a connecting round block 403, an L-shaped rod 404, an upper brush rod 405, an L-shaped rod 406, and a lower brush rod 407. The connecting round block 403 is fixedly connected to the circumferential surface of the connecting column 401, the L-shaped rod 404 is fixedly connected to the circumferential surface of the connecting round block 403, the upper brush rod 405 is fixedly connected to the inner wall of the L-shaped rod 404, the L-shaped rod 406 is fixedly connected to the circumferential surface of the connecting round block 403, and the lower brush rod 407 is fixedly connected to the inner wall of the L-shaped rod 406. The dust-proof cover 402 contacts the bracket 2, and the L-shaped rod 406 contacts the bracket 2. At the same time, during the movement of the connecting column 401, the movement of the connecting column 401 will drive the connecting round block 403 to move, the movement of the connecting round block 403 will drive the L-shaped rod 404 to move, the movement of the L-shaped rod 404 will drive the upper brush rod 405 to move, and at the same time, the connecting round block 403 on the other side will drive the L-shaped rod 406 to move, and the movement of the L-shaped rod 406 will drive the lower brush rod 407 to move. At this time, the lower brush rod 407 and the upper brush rod 405 can approach each other. After the lower brush rod 407 and the upper brush rod 405 move a certain distance, the lower brush rod 407 and the upper brush rod 405 can clean the surface of the gold jewelry to be welded of dust and sundries, avoid the reduction of welding quality caused by the presence of dust and sundries on the surface of the gold jewelry during the welding process, and improve the welding efficiency of the device.

[0017] Working principle: Before the device is started, the operator first places the ring-shaped gold jewelry to be welded on the top of the bottom bracket 9. The ring-shaped gold jewelry can be easily positioned and placed through the two bottom brackets 9. After the operator finishes placing, the sliding long plate 7 needs to be pushed into the slot of the bracket 2. The movement of the sliding long plate 7 will drive the first elastic telescopic rod 8 to move, and the movement of the first elastic telescopic rod 8 will drive the bottom bracket 9 to move. At this time, the bottom bracket 9 can reach the welding area for subsequent laser welding. Through manual placement and positioning, the gold jewelry can be more flexibly adjusted finely. Especially when facing complex or non-standard jewelry designs, the craftsman can manually adjust the position according to the actual situation to ensure the accuracy of the welding part and perfect docking, which can improve the welding accuracy and welding efficiency. When the gold jewelry on the top of the bottom bracket 9 reaches the welding area, the bidirectional motor 6 will start. The output end of the bidirectional motor 6 will drive the reciprocating lead screw 10 to rotate. The rotation of the reciprocating lead screw 10 will drive the moving plate 12 to rotate. However, at this time, the moving plate 12 will be limited by the limit post 11. At this time, the moving plate 12 can only move horizontally through the reciprocating groove on the surface of the reciprocating lead screw 10. The movement of the moving plate 12 will drive the hollow block 13 to move, the movement of the hollow block 13 will drive the second elastic telescopic rod 14 to move, the movement of the second elastic telescopic rod 14 will drive the connecting block 15 to move, and the movement of the connecting block 15 will drive the fixed block 16 to move. After the fixed block 16 moves a certain distance, the fixed block 16 will fix the ring-shaped gold jewelry through its own inclined surface, ensuring that the gold jewelry cannot move during welding, improving the welding quality of the device, reducing the welding error, and being able to reduce the welding cost.

[0018] When the device is started, the movement of the hollow block 13 drives the movement of the connecting column 401. During the movement, the connecting column 401 drives the movement of the dust-proof cover 402. At this time, after the two dust-proof covers 402 move a certain distance, the two dust-proof covers 402 can approach and fit with each other. At this time, the dust-proof cover 402 can isolate the welding area of the device from the outside world to a certain extent, avoid the welding area of the device from being polluted, ensure that during the welding of gold jewelry, foreign objects and dust in the outside world cannot contact it, avoid poor fusion at the welding part, resulting in voids, pores or uneven seams, ensure the welding quality. At the same time, during the movement of the connecting column 401, the movement of the connecting column 401 drives the movement of the connecting round block 403. The movement of the connecting round block 403 drives the movement of the first L-shaped rod 404. The movement of the first L-shaped rod 404 drives the movement of the upper brush rod 405. At the same time, the connecting round block 403 on the other side drives the movement of the second L-shaped rod 406. The movement of the second L-shaped rod 406 drives the movement of the lower brush rod 407. At this time, the lower brush rod 407 and the upper brush rod 405 can approach each other. After the lower brush rod 407 and the upper brush rod 405 move a certain distance, the lower brush rod 407 and the upper brush rod 405 can clean the dust and foreign objects on the surface of the gold jewelry to be welded, avoid the reduction of welding quality caused by the presence of dust and foreign objects on the surface of the gold jewelry during the welding process, and improve the welding efficiency of the device.

[0019] Please refer to Figures 1-8, on the basis of the above embodiments, in another embodiment of the present invention, the pushing mechanism 5 includes a nitrogen cylinder 501, a connecting pipe 502, and a gas nozzle 503. The nitrogen cylinder 501 is fixedly connected to the top of the base 1. The connecting pipe 502 is fixedly connected to the top of the nitrogen cylinder 501. The gas nozzle 503 is fixedly connected to the circumferential surface of the connecting pipe 502. When the device is started, the movement of the connecting column 401 will drive the movement of the dust cover 402. During the movement of the dust cover 402, the dust cover 402 can drive the gas nozzle 503 to move synchronously. After the movement state of the dust cover 402 ends, the gas nozzle 503 at this time can discharge the nitrogen inside the nitrogen cylinder 501 through the connecting pipe 502. The discharged nitrogen can reach the welding area, reduce the oxygen content in the welding area, protect the welding area from being polluted by water vapor and impurities in the air, can avoid the oxidation of the welding area, and can also prevent the interference of dust or other pollutants, which helps to protect the metal quality of the welding area, ensure the stability of the metal molten pool, and avoid the occurrence of pores or other defects. The pushing mechanism 5 further includes a groove block 504, a long pull rod 505, a rotating column 506, a slider 507, a transverse moving cylinder 508, and a force receiving block 509. The groove block 504 is fixedly connected to the outer surface of the dust cover 402. The long pull rod 505 is rotatably connected to the inner wall of the groove block 504. The rotating column 506 is rotatably connected to the inner wall of the long pull rod 505. The slider 507 is slidably connected to the inner wall of the bracket 2. The transverse moving cylinder 508 is fixedly connected to the front of the slider 507. The force receiving block 509 is fixedly connected to the bottom of the sliding long plate 7. The rotating column 506 is rotatably connected to the top of the slider 507. The nitrogen cylinder 501 is communicated with the connecting pipe 502, and the connecting pipe 502 is communicated with the gas nozzle 503. The connecting pipe 502 is fixedly connected to the inner wall of the dust cover 402. When the device is used up, the dust cover 402 will reciprocate through the hollow block 13 at this time. The reciprocation of the dust cover 402 can drive the movement of the groove block 504. The movement of the groove block 504 can drive the movement of the long pull rod 505. The movement of the long pull rod 505 will drive the movement of the rotating column 506. The movement of the rotating column 506 will drive the movement of the slider 507. The movement of the slider 507 will drive the movement of the transverse moving cylinder 508. After the transverse moving cylinder 508 moves a certain distance, the transverse moving cylinder 508 will contact and squeeze the force receiving block 509 to drive the force receiving block 509 to move. The movement of the force receiving block 509 will drive the movement of the sliding long plate 7, and can push the sliding long plate 7 and the gold jewelry above the sliding long plate 7 away from the welding area, and can avoid the safety hazard caused by the operator contacting the three-dimensional welding machine 3 when taking the completed welded gold jewelry, and improve the use safety of the device.

[0020] Working principle: When the device is started, the movement of the connecting column 401 drives the movement of the dust-proof cover 402. During the movement of the dust-proof cover 402, the dust-proof cover 402 can drive the gas nozzle 503 to move synchronously. After the movement state of the dust-proof cover 402 ends, the gas nozzle 503 at this time can discharge the nitrogen gas inside the nitrogen gas cylinder 501 through the connecting pipe 502. The discharged nitrogen gas can reach the welding area, reduce the oxygen content in the welding area, protect the welding area from being polluted by water vapor and impurities in the air, avoid oxidation of the welding area, prevent interference from dust or other pollutants, help protect the metal quality of the welding area, ensure the stability of the metal molten pool, and avoid the occurrence of pores or other defects. When the device is used up, the dust-proof cover 402 will reciprocate through the hollow block 13 at this time. The reciprocation of the dust-proof cover 402 can drive the movement of the groove block 504. The movement of the groove block 504 can drive the movement of the long pull rod 505. The movement of the long pull rod 505 will drive the movement of the rotating column 506. The movement of the rotating column 506 will drive the movement of the slider 507. The movement of the slider 507 will drive the movement of the transverse moving cylinder 508. After the transverse moving cylinder 508 moves a certain distance, the transverse moving cylinder 508 will contact and squeeze the force-receiving block 509 to push the force-receiving block 509 to move. The movement of the force-receiving block 509 will drive the movement of the sliding long plate 7, and can push the sliding long plate 7 and the gold jewelry above the sliding long plate 7 away from the welding area, and can avoid the safety hazard caused by the operator contacting the three-dimensional welding machine 3 when taking the welded gold jewelry, and improve the use safety of the device.
