[0002] Diamond is a very precious gemstone and has always been considered a valuable and value-preserving investment option in the market. Due to the stability and extraordinary beauty of diamonds themselves, diamond earrings have always been one of the popular choices in the jewelry market.

[0003] Diamond earrings are mainly composed of ear pins, diamond holders and diamonds. During the production process, the ear pins and diamond holders need to be accurately welded together first, and then the diamonds are set on the diamond holders.

The pneumatic conveying mechanism 2, the loading device 3, the straightening mechanism 4, the welding device 5, the assembly device 6, and the clamping mechanism 7 are arranged in sequence around the turntable 8. The ear needles 13 are first loaded, and the rotating downward pressure cylinder 23 of the pneumatic device is rotated to rotate and press the material taking tube 24 down to the top of the ear needles 13 of the ear needle loader 21. At this time, the dual-purpose vacuum pump 25 is pumped for vacuum suction. Under the action of atmospheric pressure, the ear needles 13 enter the suction hole, so that the material taking tube 24 absorbs and picks up the ear needles 13. After the rotating downward pressure cylinder 23 is rotated 90°, the material taking tube 24 is just above the spray needle tube 22. The dual-purpose vacuum pump 25 is pumped for jetting. The air pressure transports the ear needle 13 along the needle tube 22 to the positioning column 14 in the positioning block 9, and then the diamond holder 12 is loaded. Under the action of the vibration plate 31, the diamond holder 12 is orderly output through the discharge chute. The rotating swing cylinder 34 of the paste taking device rotates the dipping rod 35 to the material tank 36 to dip the solder paste. After the dipping is completed, it rotates 180° under the action of the rotating swing cylinder 34, so that the dipping rod 35 is arranged upward. The diamond holder 12 is grabbed by the first manipulator 32 and placed on the positioning block 9 after being dipped in the paste. Then, the diamond holder 12 is straightened by the straightening mechanism 4, and the first lifting cylinder 44 starts to work. The output end passes through the round hole and then pushes up. The lower ear needle 13 and the diamond holder 12 are arranged so that the diamond holder 12 is repositioned under the action of gravity. At the same time, the upper slide cylinder 42 moves downward, driving the push rod 43 to move downward together, so that the push rod 43 knocks the diamond holder 12, so that the diamond holder 12 is straightened in the installation hole. The two are welded by the welding device 5, and then the diamond is loaded into the diamond holder 12 for assembly by the assembling device 6. Finally, the diamond ear stud is unloaded by the clamping mechanism 7. This process realizes multiple steps such as fully automatic ear needle loading, diamond holder loading, welding, diamond inlay and removal, effectively improves production efficiency, thereby meeting large-scale production needs, and the products produced have high consistency, thereby ensuring product quality.

The material taking pipe 24 is connected to the dual-purpose vacuum pump 25 through an air pipe. The other end of the needle tube 22 is arranged below the material taking pipe 24. The rotary downward-pressing cylinder 23 of the pneumatic device rotates, and the material taking tube 24 is rotated and pressed down to the top of the ear needle 13 of the ear needle loader 21. At this time, the dual-purpose vacuum pump 25 is pumped for vacuum suction. Under the action of atmospheric pressure, the ear needle 13 enters the suction hole, so that the material taking tube 24 absorbs and picks up the ear needle 13. After the rotary downward-pressing cylinder 23 rotates 90°, the material taking tube 24 is just above the spray needle tube 22. The dual-purpose vacuum pump 25 is pumped for jetting, and the ear needle 13 is transported along the spray needle tube 22 to the positioning column 14 in the positioning block 9 by air pressure.

The rotating swing cylinder 34 rotates the dipping rod 35 into the material trough 36 to dip the solder paste by rotating the rotating head. After the dipping is completed, it rotates 180° under the action of the rotating swing cylinder 34, so that the dipping rod 35 is arranged upward. The diamond holder 12 is grabbed by the first manipulator 32 and placed above the dipping rod 35 for dipping in the paste and then placed on the positioning block 9. Dipping in the solder paste is conducive to more firm welding.

The mounting frame 64 is arranged on the workbench 1, and the punching cylinder 62 is installed above the mounting frame 64. The output end of the punching cylinder 62 is connected to the punching head 63. The punching gas 62 works downward to drive the punching head 63 to squeeze the buckle ears of the diamond holder 12 downward, so that the buckle ears are bent inward to buckle the diamond, so that the diamond is firmly assembled on the diamond holder. The whole process is fully automatic in loading and squeezing and bending the buckles of the diamond holder, effectively improving production efficiency.

The whole process is realized by rotating the turntable by a rotating motor to realize the flow of workstations, thereby realizing fully automatic production of diamond ear studs.

10. The control method of a rotary table type welding and drilling machine according to claim 9, characterized in that: The specific steps are as follows: S1 Ear needle loading: The pneumatic device rotates the rotary downward pressure cylinder to rotate and press the material taking tube down onto the ear needle of the ear needle loading machine. At this time, the dual-purpose vacuum pump is used to vacuum and suck air. Under the action of atmospheric pressure, the ear needle enters the suction hole, so that the material taking tube absorbs and picks up the ear needle. After the rotary downward pressure cylinder is rotated 90°, the material taking tube is just above the spray needle tube. The dual-purpose vacuum pump is used to spray air, and the ear needle is transported along the spray needle tube to the positioning column in the positioning block by air pressure. S2 Diamond holder dipping paste loading: Under the action of the vibration plate, the diamond holder is discharged in an orderly manner through the discharge chute. The rotating swing cylinder of the paste taking device rotates the rotating head to rotate the dipping rod into the material tank to dip the solder paste. After the dipping is completed, it rotates 180° under the action of the rotating swing cylinder, so that the dipping rod is arranged upward. The diamond holder is grabbed by the first manipulator to the top of the dipping rod for dipping and then placed on the positioning block; S3: Straightening the diamond holder: The first lifting cylinder starts to work. The output end passes through the round hole and pushes the ear pin and the diamond holder, so that the diamond holder is repositioned under the action of gravity. At the same time, the upper slide cylinder moves downward, driving the push rod to move downward together, so that the push rod knocks the diamond holder, so that the diamond holder is straightened in the installation hole; S4 diamond holder and ear stud are welded: the upper electrode and the lower electrode are in contact with the diamond holder and the lower electrode is in contact with the ear stud under the action of the pneumatic welding machine. Under the action of the micro cylinder, the electrode needle is inserted into the connection between the diamond holder and the ear stud, and the pneumatic welding machine is used to discharge and weld. S5 Diamonds are mounted on the diamond holder: Under the action of the vibration plate, the diamonds are orderly discharged through the discharge chute, and the diamonds are grabbed by the second manipulator and placed on the diamond holder. The punching cylinder works downward, driving the punching head to press the buckle ears of the diamond holder downward, so that the buckle ears bend inwards and buckle the diamonds tightly, so that the diamonds are firmly assembled on the diamond holder; S6 discharges the diamond earrings: the output end of the second lifting cylinder rises upward, the diamond earrings are lifted up by the lifting sleeve, and the diamond earrings are clamped and taken into the receiving trough for storage by the third manipulator.
