Description

Technical Field

[0001] This invention relates to the field of diamond earring assembly technology, and more particularly to a mechanism and control method for assembling diamonds and diamond settings. Background Technology

[0002] Diamonds are extremely precious gemstones and have long been considered a valuable investment with the potential to retain wealth. Due to their inherent stability and exceptional beauty, diamond earrings have consistently been a popular choice in the jewelry market.

[0003] Diamond earrings are mainly composed of ear posts, diamond settings, and diamonds. In the current production process, the diamond setting process for diamond earrings still requires workers to manually place the diamonds into the diamond settings and then use pliers to bend the clasps of the diamond settings to set the diamonds. This method is not only time-consuming, but also results in inconsistent processing techniques, leading to low production efficiency and an inability to supply large orders in a timely manner, thus failing to meet production needs. Summary of the Invention

[0004] The technical problem to be solved by the present invention is to address the above-mentioned shortcomings of the prior art by providing a mechanism and control method for assembling diamonds and diamond settings, which can automatically and accurately set diamonds on diamond settings, effectively improve production efficiency while maintaining product consistency, and has the characteristics of wide applicability and strong practicality.

[0005] The technical solution adopted in this invention is: a mechanism for assembling diamonds and diamond settings, including a worktable, a rotary motor on the worktable, a turntable at the output end of the rotary motor, a plurality of positioning blocks for placing diamond settings on the turntable, a vibrating plate for holding diamonds on the worktable, a discharge chute at the outlet end of the vibrating plate, a flipping mechanism for flipping diamonds on one side of the discharge chute, a column on the worktable, a gripping device for grabbing diamonds and placing them into diamond settings on the column, and a stamping device for bending the lugs of diamond settings on the worktable on one side of the gripping device.

[0006] As a further improvement, the flipping mechanism includes a mounting base, a first slide cylinder, a mounting plate, a rotary swing cylinder, and a drill bit taking device. The mounting base is mounted on the worktable, the first slide cylinder is mounted on the mounting base, the mounting plate is connected to the movable end of the first slide cylinder, the rotary swing cylinder is mounted on the mounting plate, and the output end of the rotary swing cylinder is connected to the drill bit taking device.

[0007] Furthermore, the drilling device includes a connecting sleeve and a suction pipe. One end of the connecting sleeve is connected to the output end of the rotary swing cylinder, and the other end of the connecting sleeve is connected to a vacuum pump. The suction pipe is vertically installed on the connecting sleeve and is connected to the vacuum pump through the connecting sleeve.

[0008] Furthermore, the gripping device includes an electric slide rail, a second slide cylinder, a mounting block, and a material picking tube. The electric slide rail is mounted on a column, the second slide cylinder is mounted on the slider of the electric slide rail, the mounting block is connected to the output end of the second slide cylinder, the material picking tube is mounted on the mounting block, and the upper end of the material picking tube is connected to a vacuum pump through an air pipe.

[0009] Furthermore, the stamping device includes a mounting frame, a stamping cylinder, and a stamping head. The mounting frame is arranged on a workbench, the stamping cylinder is mounted above the mounting frame, and the output end of the stamping cylinder is connected to the stamping head.

[0010] Furthermore, a lifting sleeve for lifting the diamond holder is slidably inserted into the positioning block and the turntable, and a lifting device is provided below the lifting sleeve.

[0011] Furthermore, the lifting device includes a lifting cylinder, and a push rod is connected to the output end of the lifting cylinder.

[0012] A method for controlling a mechanism for assembling diamonds and diamond settings, comprising the following specific control steps:

[0013] a. Diamond arrangement feeding: Diamonds are arranged in an orderly manner and conveyed to the discharge chute by a vibrating plate, with the larger end of the diamond facing downwards during the conveying process;

[0014] b. Diamond flipping: The mounting plate is lowered by the first slide cylinder, and at the same time the rotating swing cylinder rotates the connecting sleeve so that the suction pipe is downward and above the diamond. The vacuum pump works to make the suction pipe pick up a diamond. Then, after the first slide cylinder rises, the rotating swing cylinder rotates 180° so that the suction pipe and the diamond are upward, waiting for the gripping device to grab them.

[0015] c. Diamond loading to diamond holder: The slider is controlled by the electric slide rail to reach the top of the suction pipe. The output end of the second slide cylinder moves downward, driving the picking pipe downward. When the picking pipe comes into contact with the diamond, the vacuum pump starts to work to draw a vacuum, so that the picking pipe can adsorb the diamond. Then, under the control of the electric slide rail, the diamond is installed on the diamond holder.

[0016] d. Secure the diamond to the diamond setting: First, the lifting cylinder rises to push the lifting sleeve, which rises to hold the diamond setting. Then, the stamping cylinder works downward, driving the stamping head to press down on the diamond setting's buckle, causing the buckle to bend inward and secure the diamond, thus firmly assembling the diamond onto the diamond setting.

[0017] Beneficial effects

[0018] Compared with the prior art, the present invention has the following advantages:

[0019] The present invention relates to a mechanism and control method for assembling diamonds and diamond holders. First, a vibrating disc transports diamonds in an orderly fashion onto a discharge chute, with the larger ends of the diamonds facing downwards during transport. Then, a first sliding cylinder lowers the mounting plate, while a rotating swing cylinder rotates the connecting sleeve, causing the suction pipe to point downwards and above the diamonds. A vacuum pump operates, causing the suction pipe to pick up a diamond. After the first sliding cylinder rises, the rotating swing cylinder rotates 180°, raising the suction pipe and diamond, awaiting gripping by the gripping device. Next, an electric slide rail controls a slider to reach above the suction pipe, and the output end of a second sliding cylinder moves downwards, driving the pick-up pipe downwards. Once the pick-up pipe contacts the diamond, the vacuum pump starts working to create a vacuum, allowing the pick-up pipe to be gripped. The feed tube picks up the diamond, and then, under the control of the electric slide rail, the diamond is installed onto the diamond holder. Finally, the lifting cylinder rises to push the lifting sleeve, which rises to hold the diamond holder in place. Then, the stamping cylinder works downward, driving the stamping head to press down on the diamond holder's latch, causing the latch to bend inward and fasten the diamond, thus securing the diamond firmly onto the diamond holder. The entire process of feeding and pressing the diamond holder's latch is fully automated, effectively improving production efficiency. Furthermore, during the process of using the stamping head to bend the diamond holder, the action of first raising the diamond holder and then pressing it downward ensures the consistency of the action between the diamond holder and the diamond, effectively guaranteeing product consistency and improving product quality. It is characterized by strong practicality and wide applicability. Attached Figure Description

Detailed Implementation

[0026] The present invention will be further described below with reference to specific embodiments shown in the accompanying drawings.

[0027] See Figure 1-5As shown, a mechanism for assembling diamonds and diamond settings according to the present invention includes a worktable 1, on which a rotary motor 10 is provided. A turntable 17 is provided at the output end of the rotary motor 10. Multiple positioning blocks 6 for placing diamond settings 15 are provided on the turntable 17. A vibrating disk 7 for holding diamonds 14 is provided on the worktable 1. A discharge chute 8 is provided at the outlet end of the vibrating disk 7. A flipping mechanism 2 for flipping the diamonds 14 is provided on one side of the discharge chute 8. A column 9 is provided on the worktable 1, and a mechanism for gripping diamonds 14 and placing them into the diamond settings 15 is provided on the column 9. The gripping device 3 has a worktable 1 on one side equipped with a stamping device 4 for bending the buckle 16 of the diamond holder 15. First, the diamonds 14 are orderly arranged and conveyed to the discharge chute 8 by the vibrating plate 7. During the conveying process, the larger end of the diamonds 14 is arranged downwards to facilitate stable conveying. Then, the mounting plate 23 is lowered by the first slide cylinder 22. At the same time, the rotating swing cylinder 24 rotates the connecting sleeve 51, so that the suction pipe 52 is downwards and located above the diamonds 14. The vacuum pump works to make the suction pipe 52 pick up a diamond 14. Then, after the first slide cylinder 22 rises, the rotating swing cylinder 24 rotates the connecting sleeve 51. The cylinder 24 rotates 180°, causing the suction pipe 52 and diamond 14 to rise, awaiting grasping by the gripping device 3. Then, the electric slide rail 32 controls the slider 31 to reach above the suction pipe 52. The output end of the second slide cylinder 33 moves downward, driving the picking pipe 35 downward. When the picking pipe 35 contacts the diamond 14, the vacuum pump starts working to create a vacuum, causing the picking pipe 35 to adsorb the diamond 14. Then, under the control of the electric slide rail 32, the diamond 14 is installed onto the diamond holder 15. Finally, the lifting cylinder 13 rises to push the lifting sleeve 11, which rises and presses against the diamond holder 15. Then, the stamping cylinder 41 works downward, driving the stamping head 42 to press the ear buckle 16 of the diamond holder 15 downward, causing the ear buckle 16 to bend inward and fasten the diamond 14, thus making the diamond 14 firmly assembled on the diamond holder 15. The whole process of feeding and pressing and bending the ear buckle 16 of the diamond holder 15 is fully automatic, which effectively improves production efficiency. In addition, during the process of using the stamping head 42 to bend the diamond holder 15, by first raising the diamond holder 15 and then pressing it downward, the fitting of the diamond holder 15 and the diamond 14 can basically ensure the consistency of the action, effectively ensuring the consistency of the product and helping to improve the quality of the product.

[0028] Specifically, the flipping mechanism 2 includes a mounting base 21, a first sliding cylinder 22, a mounting plate 23, a rotary swing cylinder 24, and a drill-taking device 5. The mounting base 21 is mounted on the worktable 1, the first sliding cylinder 22 is mounted on the mounting base 21, the mounting plate 23 is connected to the movable end of the first sliding cylinder 22, the rotary swing cylinder 24 is mounted on the mounting plate 23, and the output end of the rotary swing cylinder 24 is connected to the drill-taking device 5. The drill-taking 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 24, and the other end of the connecting sleeve 51 is connected to a vacuum pump. The suction pipe 52 is vertically mounted on the connecting sleeve 51, and the suction pipe 52 is connected to the vacuum pump through the connecting sleeve 51. The mounting plate 23 is lowered by the first sliding cylinder 22, and at the same time, the rotating swing cylinder 24 rotates the connecting sleeve 51, so that the suction pipe 52 is downward and above the diamond 14. The vacuum pump works to make the suction pipe 52 pick up a diamond 14. Then, after the first sliding cylinder 22 rises, the rotating swing cylinder 24 rotates 180°, so that the suction pipe 52 and the diamond 14 are upward, waiting for the gripping device 3 to grab them, thereby realizing the flipping of the diamond 14, so that the smaller end of the diamond 14 can be set on the diamond holder 15, thus meeting the process requirements.

[0029] Furthermore, the gripping device 3 includes an electric slide rail 32, a second slide cylinder 33, a mounting block 34, and a material picking tube 35. The electric slide rail 32 is mounted on the column 9, the second slide cylinder 33 is mounted on the slider 31 of the electric slide rail 32, the mounting block 34 is connected to the output end of the second slide cylinder 33, and the material picking tube 35 is mounted on the mounting block 34. The upper end of the material picking tube 35 is connected to a vacuum pump through an air pipe. The electric slide rail 32 controls the slider 31 to reach above the suction tube 52, and the output end of the second slide cylinder 33 moves downward, driving the material picking tube 35 to move downward. When the material picking tube 35 contacts the diamond 14, the vacuum pump starts to work and draw a vacuum, so that the material picking tube 35 adsorbs the diamond 14. Then, under the control of the electric slide rail 32, the diamond 14 is installed on the diamond holder 15, thereby realizing the automatic and accurate automatic feeding of the diamond 14.

[0030] Furthermore, the stamping device 4 includes a mounting frame 43, a stamping cylinder 41, and a stamping head 42. The mounting frame 43 is arranged on the workbench 1, and the stamping cylinder 41 is installed above the mounting frame 43. The output end of the stamping cylinder 41 is connected to the stamping head 42. After the diamond 14 is installed on the diamond holder 15, the turntable 17 rotates to the next station. The lifting cylinder 13 rises and pushes the lifting sleeve 11. The lifting sleeve 11 rises and holds the diamond holder 15. Then the stamping cylinder 41 works downward, driving the stamping head 42 to press the buckle 16 of the diamond holder 15 downward, so that the buckle 16 bends inward and fastens the diamond 1. During this process, the up and down lifting action supports the diamond holder 15, so that the stamping head 42 can press the buckle 16 in the subsequent process.

[0031] Furthermore, a lifting sleeve 11 for lifting the diamond holder 15 is slidably inserted into the positioning block 6 and the turntable 17. A lifting device is provided below the lifting sleeve 11 to effectively avoid the ear pin and protect it, while also lifting the diamond holder 15.

[0032] Furthermore, the lifting device includes a lifting cylinder 13, the output end of which is connected to a push rod 12.

The vacuum pump works to make the suction pipe 52 pick up a diamond 14. Then, after the first slide cylinder 22 rises, the rotating swing cylinder 24 rotates 180°, so that the suction pipe 52 and the diamond 14 are upward, waiting for the gripping device 3 to grab them.

[0036] c. Loading diamond 14 onto diamond holder 15: The slider is controlled by electric slide rail 32 to reach above suction pipe 52. The output end of second slide cylinder 33 moves downward, driving the pick-up pipe 35 to move downward. When the pick-up pipe 35 contacts diamond 14, the vacuum pump starts to work to draw a vacuum, so that the pick-up pipe 35 adsorbs the diamond. Then, under the control of electric slide rail 32, diamond 14 is installed on diamond holder 15.

[0037] d. Secure the diamond 14 to the diamond holder 15: First, the lifting cylinder 13 rises to push the lifting sleeve 11, which rises to hold the diamond holder 15. Then, the stamping cylinder 41 works downward, driving the stamping head 42 to press the buckle 16 of the diamond holder 15 downward, causing the buckle 16 to bend inward and secure the diamond 14, thus making the diamond 14 firmly assembled on the diamond holder 15.
