[0002] With increasing global demand for high-end jewelry and fashion accessories, the diamond earring industry is becoming a key segment of the luxury goods market, and diamond stud earrings are an important component of diamond earrings. Diamond stud earrings mainly consist of an ear post, a diamond setting, and diamonds. During the production process, the ear post and diamond setting need to be welded together. In existing technology, the diamond setting and ear post are placed after being welded to a positioning block, such as... Figure 1 As shown, the two are often not centered and aligned, and the diamond setting is crooked, which causes the welded earring post to also be crooked, resulting in scrap. This leads to a high scrap rate, wastes production materials, and increases production costs. Utility Model Content
[0003] The technical problem to be solved by this utility model is to provide a diamond setting alignment mechanism that addresses the above-mentioned shortcomings of the prior art, ensuring that the diamond setting and the ear post are centered and aligned, which is beneficial for subsequent welding, improves product quality, and is convenient to use and highly practical.
[0004] The technical solution adopted by this utility model is as follows: a diamond setting straightening mechanism, 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 and earrings on the turntable, the positioning blocks having a hollow structure, a positioning post for placing earrings inside the positioning block, an installation hole for placing diamond settings on the positioning block above the positioning post, a circular hole penetrating the turntable at the lower end of the positioning post, a column on one side of the worktable, a positioning device for straightening diamond settings on the column, and a lifting device for pushing earrings upward below the turntable.
[0005] As a further improvement, the positioning device includes a slide cylinder, a connecting plate, a push rod, and a baffle. The slide cylinder is mounted on a column, the lower end of the slide cylinder's output end is connected to the connecting plate, the upper end of the slide cylinder's output end is connected to the baffle, and the push rod is movably inserted into the connecting plate.

[0009] Furthermore, the workbench is provided with a guide rod, one end of which is slidably connected to the support plate.
[0010] Beneficial effects
[0011] Compared with the prior art, this utility model has the following advantages:
[0012] This utility model discloses a diamond holder straightening mechanism. A rotary motor rotates a turntable, causing a positioning block containing the diamond holder and ear pin to rotate to a position below the positioning device and above the lifting device. The lifting cylinder of the lifting device then operates, lifting the support plate and causing the top rod to insert into the circular hole. During the upward movement, the top rod pushes against the ear pin and diamond holder, allowing the diamond holder to reposition itself under gravity. Simultaneously, the upper sliding cylinder moves downward, causing the connecting plate, top rod, and baffle to move downward together. When the top rod reaches the diamond holder, it moves upward, encountering a proximity sensor which acts as a stop. The sliding cylinder continues to move downward, causing the top rod to tap the diamond holder, thus straightening it within the mounting hole. This ensures the diamond holder and ear pin are aligned on the same central axis, facilitating subsequent welding, improving welding quality, and enhancing overall product quality. This mechanism is highly practical and has a wide range of applications. Attached Figure Description

Detailed Implementation
[0017] The present invention will be further described below with reference to specific embodiments shown in the accompanying drawings.
[0018] See Figure 2-3 As shown, the present invention discloses a diamond setting straightening mechanism, comprising a worktable 1, a rotary motor 4 on the worktable 1, a turntable 5 at the output end of the rotary motor 4, and multiple positioning blocks 6 for placing diamond settings 12 and earrings 13 on the turntable 5. Each positioning block 6 is hollow, and a positioning post 14 for placing the earrings 13 is located inside the positioning block 6. An installation hole 11 for placing the diamond settings 12 is opened on the positioning block 6 above the positioning post 14, and a circular hole 15 penetrating the turntable 5 is opened at the lower end of the positioning post 14. A column 7 is provided on one side of the worktable 1 of the turntable 5, and a positioning device 2 for straightening the diamond settings 12 is provided on the column 7. A lifting device 3 for pushing the earrings 13 upward is provided below the turntable 5. By rotating the turntable 5 through the rotary motor 4, the positioning blocks 6 containing the diamond settings 12 and earrings 13 are moved to the position below the positioning device 2. Located above the lifting device 3, the lifting cylinder 33 of the lifting device 3 starts working, lifting the support plate 32 and driving the top column 21 to insert into the round hole 15. During the upward movement, it pushes the ear pin 13 and the diamond support 12, causing the diamond support 12 to be repositioned under the action of gravity. At the same time, the upper slide cylinder 23 moves downward, driving the connecting plate 22, the top rod 21 and the stop 24 to move downward together. When the top rod 21 pushes the diamond support 12, the top rod 21 moves upward and encounters the proximity sensor 8, which acts as a blockage. The slide cylinder 23 continues to move downward, causing the top rod 21 to tap the diamond support 12, so that the diamond support 12 is aligned in the mounting hole 11, thereby making the diamond support 12 and the ear pin 13 on the same central axis, which is beneficial for subsequent welding, improves the subsequent welding quality, and helps to improve product quality.
[0019] Specifically, the positioning device 2 includes a sliding cylinder 23, a connecting plate 22, a push rod 21, and a baffle 24. The sliding cylinder 23 is mounted on the column 7. The lower end of the output end of the sliding cylinder 23 is connected to the connecting plate 22, and the upper end of the output end of the sliding cylinder 23 is connected to the baffle 24. The push rod 21 is movably inserted into the connecting plate 22 and can be inserted into the middle position of the diamond holder 12. When the sliding cylinder 23 moves downward, it drives the connecting plate 22, the push rod 21, and the baffle 24 to move downward together. When the push rod 21 hits the diamond holder 12, it moves upward and encounters the proximity sensor 8, which acts as a blockage. The sliding cylinder 23 continues to move downward, causing the push rod 21 to tap the diamond holder 12, thus straightening the diamond holder 12 in the mounting hole 11. Each time the proximity sensor 8 contacts the push rod 21, it transmits a signal to the back-end controller for feedback, thereby ensuring that the diamond holder 12 is tapped and straightened, ensuring the smooth progress of the process.
[0020] Preferably, a proximity sensor 8 is provided on the baffle 24. The proximity sensor 8 is located directly above the top rod 21. While the proximity sensor 8 acts as a blocker, it transmits a signal to the back-end controller for feedback every time it contacts the top rod 21, thereby ensuring that the diamond holder 12 is tapped and straightened, and ensuring the smooth progress of the process. The detection end of the proximity sensor 8 is provided with anti-collision silicone to protect it from damage.
[0021] Furthermore, the lower end of the top rod 21 is provided with a tapered body 9, which cooperates with the groove on the top of the diamond holder 12, so that it can be better inserted into the groove on the top of the diamond holder 12, and the diamond holder 12 can quickly return to the middle position of the mounting hole 11 after being subjected to force.
[0022] Furthermore, the lifting device 3 includes a lifting cylinder 33, a support plate 32, and a top column 31. The lifting cylinder 33 is installed on the workbench 1. The support plate 32 is connected to the output end of the lifting cylinder 33. The top column 31 is aligned with the round hole 15 on the support plate 32. When the lifting cylinder 33 starts working, it lifts the support plate 32, causing the top column 21 to be inserted into the round hole 15. During the upward movement, it pushes the ear pin 13 and the diamond holder 12, causing the diamond holder 12 to loosen slightly so that it can be repositioned under the action of gravity, thereby achieving the effect of straightening.
[0023] Furthermore, the workbench 1 is provided with a guide rod 10, one end of which is slidably connected to the support plate 32. The guide rod 10 plays a guiding role, making the support plate 32 run more stably.
[0024] In this embodiment, the diamond holder straightening mechanism rotates the turntable 5 via the rotary motor 4, thereby moving the positioning block 6, which contains the diamond holder 12 and the ear pin 13, to a position below the positioning device 2 and above the lifting device 3. The lifting cylinder 33 of the lifting device 3 then operates, lifting the support plate 32 and causing the top column 21 to insert into the round hole 15. During the upward movement, the top column 21 pushes against the ear pin 13 and the diamond holder 12, causing the diamond holder 12 to be repositioned under gravity. Simultaneously, the upper sliding cylinder 23 moves downward, causing the connecting plate 22, the top rod 21, and the stop 24 to move downward together. When the top rod 21 hits the diamond holder 12, it moves upward and encounters the proximity sensor 8, which acts as a stop. The sliding cylinder 23 continues to move downward, causing the top rod 21 to tap the diamond holder 12, thus straightening the diamond holder 12 in the mounting hole 11. This ensures that the diamond holder 12 and the ear pin 13 are on the same central axis, which is beneficial for subsequent welding, improves the welding quality, and enhances the overall product quality. This utility model provides a diamond setting alignment mechanism that ensures the diamond setting and ear post are centered and aligned, which is beneficial for subsequent welding, improves product quality, and is characterized by ease of use and strong practicality.
[0025] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several modifications and improvements can be made without departing from the structure of the present utility model. These modifications and improvements will not affect the effectiveness of the present utility model or the practicality of the patent.
