Technical Field
[0001] This invention relates to the field of jewelry and gemstone chain production technology, and in particular to an automatic assembly and diamond setting machine for gemstone chains and its control method. Background Technology
[0002] In jewelry design, the gemstone setting is a crucial component used to secure gemstones and set them into the jewelry. Multiple gemstone settings are interconnected through a specific connecting structure, incorporating clasps and end caps, and finally, diamonds are set into the settings to form complete chain-like jewelry such as gemstone bracelets and necklaces. Traditionally, gemstone settings are assembled primarily by welding, followed by manual setting of the gemstones. This method is not only cumbersome and inefficient but also requires highly skilled operators, making it unsuitable for modern large-scale production.
[0003] like Figure 1 As shown, to overcome the aforementioned shortcomings, a new snap-fit gemstone setting connection structure has been developed on the market. This structure allows for a quick and stable connection between adjacent gemstone settings through a simple snap-fit action, effectively improving the assembly speed of individual connection points. However, connecting multiple gemstone settings sequentially into a chain of predetermined length, precisely installing buckles and clasps at both ends of the chain to form a closed loop, and finally performing hand-setting of diamonds—this series of operations still mainly relies on manual labor. Manual operation is not only labor-intensive and inefficient, but also makes it difficult to guarantee the consistency and stability of product assembly quality. This has become a bottleneck restricting further increases in the production capacity of the entire jewelry industry. Summary of the Invention

[0013] Furthermore, the workbench is equipped with a PLC touch screen all-in-one machine for controlling the operation of the entire device.
[0014] A control method for an automated gemstone chain assembly and diamond setting machine, the specific operation steps of which are as follows: Step S1: The operator pours the chain buckle head, snap-on gemstone drag and chain buckle tail into the first vibrating plate, the second vibrating plate and the third vibrating plate in batches respectively; after the three vibrating plates are started, the disorderly piled materials are arranged in an orderly manner through high-frequency vibration, and are transported to the predetermined grab position through their respective discharge chute, so as to realize the automated queuing and feeding of three different materials. Step S2: Start the gripping and feeding assembly. The second electric slide rail drives the second slide cylinder to move above the discharge port of the first vibrating plate. The second slide cylinder drives the pneumatic finger to descend. The pneumatic finger drives the gripper to grab the chain buckle. Then the second slide cylinder rises and resets. The second electric slide rail drives the gripping and feeding assembly to move above the corresponding station of the assembly slide rail. The second slide cylinder descends again. The gripper releases the chain buckle and places it in the slide groove of the assembly slide rail. Step S3: The propulsion component located at the front end of the assembly slide rail is activated. The first cylinder pushes the plug rod to extend, so that the plug rod is inserted into the long slot of the assembly slide rail and into the hole of the chain buckle. The first slide cylinder moves forward, pushing the chain buckle to move forward along the assembly slide rail to move one station. Step S4: The grabbing and feeding component moves sequentially to above the discharge port of the second vibrating plate, grabs the snap-on gemstone slings with the grippers, and transfers them into the assembly slide rail to engage with the pre-positioned chain buckle. The propulsion component located below the first assembly station is activated, pushing the snap-on gemstone slings forward. Subsequently, the grabbing and feeding component continues to pick up materials from the second vibrating plate, sequentially placing multiple snap-on gemstone slings into the assembly slide rail one by one. Each time a snap-on gemstone sling is placed, the insertion rod of the propulsion component extends and inserts into the hole of the placed snap-on gemstone sling, advancing one station forward, realizing the sequential end-to-end engagement of multiple snap-on gemstone slings. This process is repeated until the predetermined number of snap-on gemstone slings are all assembled. Step S5: Use the gripping and feeding assembly to move to the top of the discharge port of the third vibrating plate, use the grippers to grab the chain buckle tail and transfer it into the assembly slide rail, so that the chain buckle tail is engaged with the last snap-on gemstone drag. Step S6: The first electric slide rail is activated, driving the traction device to move along the assembly slide rail direction to the rear of the chain unit. The third slide cylinder drives the clamp to descend, so that the traction rod is aligned with the slide groove of the assembly slide rail and abuts against the chain unit. The first electric slide rail drives the traction device in the opposite direction, and the traction rod pushes the chain unit forward along the assembly slide rail by one step to the diamond setting position. Step S7: The fourth vibrating plate arranges the diamonds in an orderly manner and conveys them to the material picking position of the flipping mechanism; the flipping mechanism is started, the fourth slide cylinder drives the mounting base to descend, so that the lower end of the suction pipe of the diamond picking device contacts the diamond, the vacuum pump is started to create negative pressure in the suction pipe to adsorb the diamond; the fourth slide cylinder drives the mounting base to rise and reset, the rotary swing cylinder drives the diamond picking device to rotate 180°, flipping the diamond from a horizontal state to a vertical state; Step S8: The diamond-grabbing device is activated. The push-pull cylinder drives the fifth slide cylinder to move along the first slide rail to above the flipping mechanism. The fifth slide cylinder drives the mounting block to descend, so that the lower end of the pick-up tube contacts the diamond. The vacuum pump switches to create negative pressure in the pick-up tube to remove the diamond from the suction tube. The fifth slide cylinder rises to reset. The push-pull cylinder reverses and drives the fifth slide cylinder to move to above the snap-on gemstone holder at the diamond setting station. The fifth slide cylinder descends again, so that the pick-up tube places the diamond into the diamond setting slot of the snap-on gemstone holder. The vacuum pump is turned off to release the diamond. Step S9: The pressing devices on both sides of the assembly slide rail are activated simultaneously. The telescopic cylinder pushes the pressing plate to slide along the guide block towards the assembly slide rail. The pressing plates on both sides apply pressure to the buckles on both sides of the snap-on gemstone holder, causing the buckles to bend inward and press the edge of the diamond, thus completing the diamond setting and locking. During the diamond setting process, the device moves forward through the push component installed below. Step S10: The first electric slide rail is started again, and the traction device pushes the assembled chain unit to continue moving forward along the assembly slide rail to the discharge end, completing the automatic unloading.
[0015] Beneficial effects Compared with the prior art, the present invention has the following advantages: 1. This invention automatically sorts and feeds chain buckle heads, snap-on gemstone slings, and chain buckle tails by setting up a first vibrating plate, a second vibrating plate, and a third vibrating plate, respectively. Combined with a gripping and feeding component, it realizes fully automatic gripping and assembly of the three materials, which greatly reduces manual intervention and lowers the labor intensity of operators.
[0016] 2. This invention utilizes the insertion rod of the propulsion component to insert into the hole of the snap-fit gemstone holder and advance it one station, thereby realizing the sequential end-to-end snap-fit connection between multiple snap-fit gemstone holders. The entire process is carried out automatically in a cycle, which significantly improves assembly efficiency compared to the traditional manual snap-fit method.
[0017] 3. This invention integrates the automatic assembly functions of chain buckle head, snap-on gemstone tether, and chain buckle tail with the automatic diamond setting function on the same equipment. After the chain unit is assembled, it can be directly transferred to the diamond setting station for diamond setting operations via a traction device, without the need to transfer the workpiece in the middle, reducing the workpiece handling links and improving the overall production cycle.
[0018] 4. This invention automatically supplies diamonds through a fourth vibrating plate, a flipping mechanism flips the diamonds from a horizontal to a vertical position, a diamond gripping device accurately places the diamonds into the diamond setting slots of the snap-on gemstone holder, and finally, the two side squeezing devices simultaneously bend and lock the clasp. The entire diamond setting process is automated, effectively ensuring the consistency of the setting angle, depth and locking force of each diamond, and greatly improving the product yield.

Detailed Implementation
[0021] The present invention will be further described below with reference to specific embodiments shown in the accompanying drawings.
[0022] See Figure 1-11As shown, an automatic assembly and diamond setting machine for gemstone chains according to the present invention includes a worktable 1. The worktable 1 is equipped with a first vibrating plate 9, a second vibrating plate 10, and a third vibrating plate 11 for placing chain buckles 18, snap-on gemstone holders 17, and chain buckle tails 19, respectively. A gantry frame 12 is provided on the worktable 1, and a gripping and feeding assembly 3 for gripping the chain buckles, snap-on gemstone holders 17, and chain buckle tails is provided on the gantry frame 12. An assembly slide rail 13 is provided below the gantry frame 12, and a pushing assembly 2 for moving the chain forward is provided at the front end of the assembly slide rail 13. A side of the assembly slide rail 13 is provided with… A first electric slide rail 15 is arranged parallel to the assembly slide rail 13. The first electric slide rail 15 is equipped with a traction device 4 for pulling the chain to slide. On the other side of the assembly slide rail 13, a fourth vibrating plate 16 for holding diamonds is provided. On one side of the discharge chute of the fourth vibrating plate 16, a flipping mechanism 8 for flipping diamonds is provided. Above the flipping mechanism 8, a diamond grabbing device 6 for grabbing diamonds and placing them in the gemstone tray is provided. On both sides of the assembly slide rail 13, there are extrusion devices 7 for bending the buckles of the gemstone tray. Below the extrusion device 7 of the assembly slide rail 13, there is also a pushing component 2 for moving the chain forward.
[0023] In this embodiment, the first vibrating plate 9, the second vibrating plate 10, and the third vibrating plate 11 respectively arrange and transport the chain buckle head 18, the snap-on gemstone drag 17, and the chain buckle tail 19 to their respective gripping positions; the gripping and feeding assembly 3 moves back and forth on the gantry frame 12, sequentially gripping the chain buckle head 18, multiple snap-on gemstone drags 17, and chain buckle tail 19 from the discharge port of each vibrating plate and placing them into the groove of the assembly slide rail 13 for engagement; the pushing assembly 2 located at the front end of the assembly slide rail 13 inserts its insertion rod 24 into the holes of each workpiece sequentially, thus engaging each... The workpieces are advanced forward to achieve sequential locking, forming a complete chain unit; the traction device 4 pulls the assembled chain unit forward along the assembly slide rail 13 to the diamond setting station; the fourth vibrating plate 16 arranges the diamonds in an orderly manner and conveys them to the material picking position of the flipping mechanism 8, which flips the flat diamonds to a vertical position; the diamond grabbing device 6 removes the diamonds from the flipping mechanism 8 and places them into the diamond setting slot of the snap-on gemstone holder 17; the pressing device 7 applies pressure to the buckle lugs of the snap-on gemstone holder 17 from both sides, causing the buckle lugs to bend inward and press the edge of the diamond, completing the diamond setting and locking. By integrating the three major functions of automatic feeding, automatic assembly, and automatic diamond setting into the same equipment, fully automated continuous production from bulk materials to finished diamond-set chains is realized. The layout of multiple vibratory feeders allows for the simultaneous automated queuing and feeding of four different material forms: chain buckle heads, snap-on gemstone trolleys, chain buckle tails, and diamonds, without interference between them. The vertical arrangement of the gantry frame 12 and the assembly slide rail 13 minimizes the movement path of the gripping and feeding component 3, effectively shortening the feeding cycle of a single workpiece. The traction device 4 and diamond setting mechanisms are arranged on both sides of the assembly slide rail 13, allowing the assembly and diamond setting processes to proceed in parallel in space without interference, which is conducive to achieving streamlined operations. The propulsion component 2, located below the extrusion device 7, can simultaneously move the chain during the diamond setting process, achieving seamless connection between assembly and diamond setting, and significantly improving the overall production cycle.
[0024] Furthermore, the propulsion component 2 includes a support column 21, a first slide cylinder 23, a mounting plate 25, a first cylinder 22, and a connecting rod 24. The support column 21 is mounted on the worktable 1, the first slide cylinder 23 is mounted on the support column 21, the mounting plate 25 is mounted on the moving end of the first slide cylinder 23, the first cylinder 22 is mounted on the lower end of the mounting plate 25, and the connecting rod 24 is slidably inserted into the upper end of the mounting plate 25. One end of the connecting rod 24 is connected to the output end of the first cylinder 22, and the other end of the connecting rod 24 is inserted into the long slot of the assembly slide rail 8. Initially, the connector rod 24 is in the retracted position. When the workpiece needs to be pushed, the first cylinder 22 is activated, its output end extends, and pushes the connector rod 24 upward, so that the upper end of the connector rod 24 passes through the long slot of the assembly slide rail 13 and inserts into the hole of the workpiece. Then, the first slide cylinder 23 is activated, its movable end moves forward, driving the mounting plate 25 and the connector rod 24 forward together. The connector rod 24 drives the workpiece to slide forward one position along the assembly slide rail 13. After reaching the predetermined position, the first cylinder 22 reverses its action, pulling the connector rod 24 downward to retract, so that the connector rod 24 disengages from the hole of the workpiece. Finally, the first slide cylinder 23 reverses its action, driving the connector rod 24 to return to its original position, ready for the next push. This push assembly 2 has a compact structure and reliable operation, and can achieve precise stepping of one position each time, providing precise positional guarantee for the sequential end-to-end locking connection between multiple snap-fit gemstone drags 17. Furthermore, the gripping and feeding assembly 3 includes a second electric slide rail 31, a second slide cylinder 32, a pneumatic finger 33, and a gripper 34. The second electric slide rail 31 is mounted on the gantry frame 12, the second slide cylinder 32 is mounted on the slider of the second electric slide rail 31, the output end of the second slide cylinder 32 is provided with a pneumatic finger 33, and the gripper 34 is mounted on the two output ends of the pneumatic finger 33. The second electric slide rail 31 drives the second slide cylinder 32 and pneumatic fingers 33 to move above the discharge port of the target vibratory feeder; the second slide cylinder 32 drives the pneumatic fingers 33 to descend, so that the grippers 34 reach both sides of the workpiece; the pneumatic fingers 33 drive the grippers 34 to close, gripping the workpiece; the second slide cylinder 32 rises to reset, removing the workpiece from the discharge port; the second electric slide rail 31 drives the second slide cylinder 32 and the workpiece to move above the corresponding station of the assembly slide rail 13; the second slide cylinder 32 descends again, so that the workpiece reaches the groove of the assembly slide rail 13; the pneumatic fingers 33 drive the grippers 34 to open, releasing the workpiece, so that it falls into the groove of the assembly slide rail 13 and is engaged with the previous component. Through the above process, the gripping and feeding assembly 3 can transfer the chain buckle 18, the snap-on gemstone drag 17 and the chain buckle tail 19 from their respective vibratory feeder ports to the predetermined positions of the assembly slide rail 13 for engagement.
[0025] Furthermore, the traction device 4 includes a movable base plate 41, a third slide cylinder 42, a clamp 43, and a traction rod 44. The movable base plate 41 is mounted on the slider of the first electric slide rail 10, the third slide cylinder 42 is mounted on the movable base plate 41, the clamp 43 is connected to the output end of the third slide cylinder 42, one end of the traction rod 44 is mounted on the clamp 43, and the other end is aligned with the slide groove of the assembled slide rail 13. When the assembled chain unit needs to be pulled, the first electric slide rail 15 drives the moving base plate 41 to move along the first electric slide rail 15 to the rear position of the chain unit; the third slide cylinder 42 is activated, its output end extends downward, driving the clamp 43 and the traction rod 44 to descend, so that the end of the traction rod 44 aligns with the slide groove of the assembly slide rail 13 and abuts against the hole at the tail end of the chain unit; the first electric slide rail 15 reverses its drive, the moving base plate 41 moves forward, and the traction rod 44 pushes the chain unit to slide forward along the assembly slide rail 13; when the chain unit reaches the predetermined position, the third slide cylinder 42 reverses its action, the traction rod 44 rises and resets, disengaging from the hole of the chain unit; the first electric slide rail 15 reverses its drive again, and the traction rod 44 moves backward and resets, preparing for the next pulling action. The pulling device 4 is set independently of the propulsion component 2 and is specifically responsible for transferring the assembled chain unit from the assembly area to the diamond setting area, realizing the automatic connection between the assembly process and the diamond setting process. Further, the flipping mechanism 8 includes a mounting base 83, a fourth sliding cylinder 82, a column 81, a rotary swing cylinder 84, and a drill-taking device 5. The column 81 is mounted on the worktable, the fourth sliding cylinder 82 is mounted on the column 81, the mounting base 83 is connected to the movable end of the fourth sliding cylinder 82, the rotary swing cylinder 84 is mounted on the mounting base 83, and the output end of the rotary swing cylinder 84 is connected to the drill-taking device 5. At the end of the discharge chute of the fourth vibrating plate 16, the diamond is output in a flat position and awaits collection; the fourth sliding cylinder 82 is activated, its movable end extends downward, driving the mounting base 83 and the rotary swing cylinder 84 and drill-taking device 5 mounted thereon to descend together, so that the lower end of the suction pipe 52 of the drill-taking device 5 contacts the diamond; the vacuum pump is activated, causing the suction pipe 52 to generate negative pressure to adsorb the diamond; the fourth sliding cylinder 82 reverses its action, its movable end retracts upward, taking the diamond out of the discharge chute; the rotary swing cylinder 84 is activated, its output end retracts upward, and the drill-taking device 5 continues to descend. The output end rotates 180°, causing the drill-grabbing device 5 and the diamond adsorbed on it to rotate 180° together, turning the diamond from a horizontal state to a vertical state, so that the drill-grabbing device 6 can take the diamond from above. Through the combined movement of the fourth slide cylinder 82 and the rotary swing cylinder 84, the two actions of diamond picking and turning are completed in one step, simplifying the equipment structure. Turning the diamond from a horizontal state to a vertical state allows the drill-grabbing device 6 to take the diamond vertically from directly above, which helps to improve the positioning accuracy and success rate of drill picking.
[0026] Furthermore, the diamond extraction device 5 includes a connecting sleeve 51 and a suction pipe 52. One end of the connecting sleeve 51 is connected to the output end of the rotary swing cylinder 84, and the other end of the connecting sleeve 51 is connected to a vacuum pump. The suction pipe 52 is vertically installed on the connecting sleeve 51 and is connected to the vacuum pump through the connecting sleeve 51. After the vacuum pump is started, a negative pressure environment is formed inside the connecting sleeve 51 and the suction pipe 52. When the lower end of the suction pipe 52 contacts the diamond surface, the diamond is tightly adsorbed at the adsorption port of the suction pipe 52 under atmospheric pressure. When it is necessary to release the diamond, the vacuum pump stops working or switches to blowing mode, the negative pressure in the suction pipe 52 disappears, and the diamond naturally detaches from the suction pipe 52 under gravity. The lower end of the suction pipe 52 is provided with an adsorption port that matches the shape of the diamond, which can form a good sealing contact with the diamond surface and ensure sufficient adsorption force. The suction pipe 52 is made of flexible material, which can effectively avoid damage to the diamond surface during adsorption and release.
[0027] Furthermore, the drilling device 6 includes a mounting frame 63, a first slide rail 64, a fifth slide cylinder 62, a mounting block 66, a material taking pipe 65, and a push-pull cylinder 61. The mounting frame 63 is mounted on the upright. The first slide rail 64 and the push-pull cylinder 61 are both mounted on the mounting frame 63. The fifth slide cylinder 62 is connected to the slider on the first slide rail 64. The output end of the push-pull cylinder 61 is connected to the slider. The mounting block 66 is connected to the movable end of the fifth slide cylinder 62. The material taking pipe 65 is mounted on the mounting block 66. The upper end of the material taking pipe 65 is connected to the vacuum pump through an air pipe.
[0028] After the flipping mechanism 8 flips the diamond to a vertical position, the push-pull cylinder 61 is activated, and its output end pushes the slider to slide along the first slide rail 64, causing the fifth slide cylinder 62 and the material picking tube 65 to move directly above the diamond picking device 5 of the flipping mechanism 8; the fifth slide cylinder 62 is activated, and its movable end extends downward, driving the mounting block 66 and the material picking tube 65 to descend, so that the lower end of the material picking tube 65 contacts the upper surface of the diamond; the vacuum pump switches its working state, creating negative pressure in the material picking tube 65, and removing the diamond from the suction tube 52; the fifth slide cylinder 62 reverses its action, and its movable end retracts upward, removing the diamond from the diamond picking device 5; the push-pull cylinder 61 reverses its action, driving the fifth slide cylinder 62 and the material picking tube 65 to move along the first slide rail 64 to the snap-fit position of the diamond setting station. Directly above the gemstone holder 17; the fifth slide cylinder 62 descends again, causing the pick-up tube 65 to place the diamond into the diamond setting slot of the snap-on gemstone holder 17; the vacuum pump is turned off, the negative pressure of the pick-up tube 65 is released, and the diamond is released into the diamond setting slot; the fifth slide cylinder 62 rises to reset, completing one diamond pick-up and drop-off action. The diamond gripping device 6 is set independently of the flipping mechanism 8, and achieves horizontal movement through the push-pull cylinder 61 and the first slide rail 64, and vertical lifting and lowering through the fifth slide cylinder 62. It has independent two-degree-of-freedom motion capability and can flexibly move back and forth between the diamond pick-up position of the flipping mechanism 8 and the diamond setting position; the pick-up tube 65 uses a vacuum adsorption method to pick up and drop diamonds, which is consistent with the adsorption method of the diamond pick-up device 5, realizing the non-destructive transfer of diamonds between different positions.
[0029] Furthermore, the extrusion device 7 includes a telescopic cylinder 72, an extrusion plate 73, and a guide block 74. The telescopic cylinder 72 is mounted on the workbench 1 via a vertical plate 71, and the guide block 74 is mounted on the assembly slide rail 13. One end of the extrusion plate 73 is slidably inserted into the guide block 74, and the other end is connected to the output end of the telescopic cylinder 72. When a diamond is placed into the setting slot of the snap-on gemstone holder 17, the telescopic cylinders 72 located on both sides of the assembly slide rail 13 are activated simultaneously. Their output ends extend and push the pressing plates 73 to slide along the guide block 74 towards the assembly slide rail 13. The pressing plates 73 on both sides simultaneously approach the snap-on gemstone holder 17, and their pressing slopes or pressing arc surfaces contact the buckles on both sides of the snap-on gemstone holder 17 and apply inward pressing force. Under the action of the pressing force, the buckles gradually bend inward from a vertical position, and finally bend and press against the edge of the diamond, firmly locking the diamond in the setting slot, completing the diamond setting. The telescopic cylinders 72 move in the opposite direction, and their output ends retract, driving the pressing plates 73 to reset in a direction away from the assembly slide rail 13, releasing the pressing force on the snap-on gemstone holder 17. The pressing devices 7 are symmetrically arranged on both sides of the assembly slide rail 13, which can apply uniform pressing force to the buckles of the snap-on gemstone holder 17 from both sides at the same time, ensuring that the buckle bending angle is consistent and the locking force is balanced, effectively improving the consistency of diamond setting quality.
[0030] Furthermore, the workbench 1 is equipped with a PLC touch screen all-in-one machine 14 that controls the operation of the entire device. The PLC touch screen all-in-one machine 14 integrates the control core and the human-machine interface into one, simplifying the structure of the electrical control system and reducing the space occupied by the equipment; operators can intuitively monitor the operating status of the equipment and adjust process parameters through the touch screen, realizing intelligent human-machine interaction of the equipment.
[0031] A control method for an automated gemstone chain assembly and diamond setting machine, the specific operation steps of which are as follows: Step S1: The operator pours the chain buckle head 18, the snap-on gemstone drag 17 and the chain buckle tail 19 into the first vibrating plate 9, the second vibrating plate 10 and the third vibrating plate 11 in batches respectively; after the three vibrating plates are started, the randomly piled materials are arranged in an orderly manner through high-frequency vibration, and are transported to the predetermined grab position through their respective discharge chute, so as to realize the automated queuing and feeding of three different materials. Step S2: Start the gripping and feeding assembly 3. The second electric slide rail 31 drives the second slide cylinder 32 to move above the discharge port of the first vibrating plate 9. The second slide cylinder 32 drives the pneumatic finger 33 to descend. The pneumatic finger 33 drives the gripper 34 to grip the chain buckle 18. Then the second slide cylinder 32 rises and resets. The second electric slide rail 31 drives the gripping and feeding assembly 3 to move above the corresponding station of the assembly slide rail 13. The second slide cylinder 32 descends again. The gripper 34 releases the chain buckle 18 and places it in the groove of the assembly slide rail 13. Step S3: The push assembly 2 located at the front end of the assembly slide rail 13 is activated. The first cylinder 22 pushes the plug rod 24 to extend, so that the plug rod 24 is inserted into the long slot of the assembly slide rail 13 and into the hole of the chain buckle 18. The first slide cylinder 23 moves forward, pushing the chain buckle 18 to move forward along the assembly slide rail 13 to move one station. Step S4: The grabbing and feeding component 3 moves sequentially to the outlet of the second vibrating plate 10, and uses the gripper 34 to grab the snap-on gemstone drag 17 and transfer it into the assembly slide rail 13 to engage with the positioned chain buckle 18; the push component 2 located below the first assembly station is activated, pushing the snap-on gemstone drag 17 forward. Then, the grabbing and feeding component 3 continues to pick up materials from the second vibrating plate 10 and sequentially places multiple snap-on gemstone drags 17 into the assembly slide rail 13 one by one. Each time a snap-on gemstone drag 17 is placed, the insertion rod 24 of the push component 2 extends and inserts into the hole of the placed snap-on gemstone drag 17, and moves forward one station, realizing the sequential head-to-tail engagement connection between multiple snap-on gemstone drags 17. This cycle is repeated until the predetermined number of snap-on gemstone drags 17 are all assembled. Step S5: Use the gripping and feeding component 3 to move above the discharge port of the third vibrating plate 11, use the gripper 34 to grip the chain buckle 19 and transfer it into the assembly slide rail 13, so that the chain buckle 19 is engaged with the last snap-on gemstone drag 17. Step S6: The first electric slide rail 15 is activated, driving the traction device 4 to move along the assembly slide rail 13 to the rear of the chain unit. The third slide cylinder 42 drives the clamp 43 to descend, so that the traction rod 44 is aligned with the slide groove of the assembly slide rail 13 and abuts against the chain unit. The first electric slide rail 15 drives the traction device 4 in the opposite direction, and the traction rod 44 pushes the chain unit to move forward one step along the assembly slide rail 13 to the diamond setting position. Step S7: The fourth vibrating plate 16 arranges the diamonds in an orderly manner and conveys them to the material picking position of the flipping mechanism 8; the flipping mechanism 8 is started, the fourth slide cylinder 82 drives the mounting base 83 to descend, so that the lower end of the suction pipe 52 of the diamond picking device 5 contacts the diamond, the vacuum pump is started to generate negative pressure in the suction pipe 52 to adsorb the diamond; the fourth slide cylinder 82 drives the mounting base 83 to rise and reset, and the rotary swing cylinder 84 drives the diamond picking device 5 to rotate 180°, flipping the diamond from a horizontal state to a vertical state; Step S8: The diamond-grabbing device 6 is activated. The push-pull cylinder 61 drives the fifth slide cylinder 62 to move along the first slide rail 64 to above the flipping mechanism 8. The fifth slide cylinder 62 drives the mounting block 66 to descend, so that the lower end of the pick-up tube 65 contacts the diamond. The vacuum pump switches to generate negative pressure in the pick-up tube 65 to remove the diamond from the suction tube 52. The fifth slide cylinder 62 rises to reset. The push-pull cylinder 61 drives the fifth slide cylinder 62 in the opposite direction to move it to above the snap-on gemstone holder 17 in the diamond setting station. The fifth slide cylinder 62 descends again, so that the pick-up tube 65 puts the diamond into the diamond setting slot of the snap-on gemstone holder 17. The vacuum pump is turned off to release the diamond. Step S9: The pressing devices 7 located on both sides of the assembly slide rail 13 are activated simultaneously. The telescopic cylinder 72 pushes the pressing plate 73 to slide along the guide block 74 towards the assembly slide rail 13. The pressing plates 73 on both sides apply pressing force to the buckles on both sides of the snap-on gemstone holder 17, causing the buckles to bend inward and press the edge of the diamond, thus completing the diamond setting and locking. During the diamond setting process, the device moves forward through the push component 2 installed below. Step S10: The first electric slide rail 15 is started again, and the traction device 4 pushes the assembled chain unit to continue moving forward along the assembly slide rail 13 to the discharge end, completing the automatic unloading.
