Detailed Implementation

[0017] The present invention will be further described below with reference to specific embodiments shown in the accompanying drawings.

[0018] See Figure 1-3 As shown, this utility model discloses an automatic earring polishing device, comprising a machine frame 1, an earring feeder 2 for feeding earrings is provided at one end of the machine frame 1, a first cylinder 5 is provided on one side of the machine frame 1 of the earring feeder 2, a pneumatic rotary cylinder 6 is provided on the output end of the first cylinder 5, a pneumatic gripping device for picking up and placing earrings 16 is provided on the pneumatic rotary cylinder 6, and a clamping device 3 for fixing earrings 16 is provided on one side of the machine frame 1 of the pneumatic rotary cylinder 6. A grinding device 4 is located below the clamping device 3. A photoelectric sensor 7 is located on one side of the clamping device 3 to detect whether the earring 16 is in position. The pneumatic rotary cylinder 6 rotates one end of the rotating rod 8 with the picking tube 9 to the top of the earring feeding machine 2. The first cylinder 5 operates, driving the pneumatic rotary cylinder 6 and the picking tube 9 to descend. At the same time, the air compressor 11 starts working, and the vacuum generator 10 evacuates the picking tube 9, thereby allowing the picking tube 9 to pick up the earring 16. After the ear pin 16 is picked up, the first cylinder 5 drives the pneumatic rotary cylinder 6 and the material picking tube 9 to rise. Then, the pneumatic rotary cylinder 6 rotates one end of the rotating rod 8 with the material picking tube 9 above the grinding device 4. The first cylinder 5 descends, inserting the ear pin 16 into the needle placement hole 18 between the first fixing block 32 and the second fixing block 31. At the same time, the second cylinder 34 is activated, pushing the slider 33 to clamp the ear pin 16. Then, the motor 43 is activated, driving the rotating shaft 42 to rotate through the belt drive mechanism. The grinding head 41 grinds the lower end of the ear needle 16. After grinding, with the cooperation of the first cylinder 5 and the pneumatic rotary cylinder 6, when the material picking pipe 9 reaches the discharge port 14, the air compressor 11 stops working, the vacuum generator 10 stops vacuuming, and the ear needle 16 falls from the material picking pipe 9 into the collection box 13 for collection. The whole movement process is simple and effective, and the ear needle 16 is quickly and effectively picked up and ground into the grinding device, thus realizing automated production and effectively improving production efficiency.

[0019] Specifically, a feeding port 14 is provided inside the frame 1 on one side of the first cylinder 5, and a collection box 13 is provided below the feeding port 14. The collection box 13 is used to collect the polished ear pins 16, which is convenient for operators to operate.

[0020] Preferably, the pneumatic gripping device includes a rotating rod 8, a material picking tube 9, an air compressor 11, and a vacuum generator 10. The middle part of the rotating rod 8 is connected to the output end of the pneumatic rotary cylinder 6. The material picking tube 9 is installed at one end of the rotating rod 8. The air intake of the vacuum generator 10 is connected to the material picking tube 9 through a hose 17. The air inlet of the vacuum generator 10 is connected to the air compressor 11. When the first cylinder 5 operates, it drives the pneumatic rotary cylinder 6 and the material picking tube 9 to descend. At the same time, the air compressor 11 starts to operate and uses the vacuum generator 10 to evacuate the material picking tube 9, so that the material picking tube 9 can pick up the ear needle 16. After the material picking tube 9 picks up the ear needle 16, the first cylinder 5 drives the pneumatic rotary cylinder 6 and the material picking tube 9 to rise. Then, the pneumatic rotary cylinder 6 rotates one end of the rotating rod 8 with the material picking tube 9 to the top of the grinding device 4. By using the vacuum needle suction method, the ear needle 16 can be quickly and accurately adsorbed and picked up.

[0021] Furthermore, the clamping device 3 includes a first fixing block 32, a second fixing block 31, a slider 33, and a second cylinder 34. The first fixing block 32 and the second fixing block 31 are respectively fixed on the machine frame 1. A needle placement hole 18 for placing the ear needle 16 is opened between the first fixing block 32 and the second fixing block 31. The second cylinder 34 is installed on the machine frame 1. The output end of the second cylinder 34 is connected to the slider 33. The slider 33 is slidably installed at the bottom of the first fixing block 32. When the ear needle 16 is inserted into the needle placement hole 18 between the first fixing block 32 and the second fixing block 31, the second cylinder 34 is activated, pushing the slider 33 to clamp the ear needle 16, making the ear needle 16 more stable during the polishing process.

[0022] Furthermore, the polishing device 4 includes a motor 43, a rotating shaft 42, and a polishing head 41. The motor 43 is mounted on the body frame 1 via a support plate. The rotating shaft 42 is rotatably mounted on the mounting base 44 of the body frame 1. The polishing head 41 is mounted on the upper end of the rotating shaft 42. The lower end of the rotating shaft 42 is connected to the output end of the motor 43 via a belt drive mechanism. When the motor 43 is started, it drives the rotating shaft 42 to rotate via the belt drive mechanism, thereby driving the polishing head 41 to polish the lower end of the ear stud 16, thus preventing the lower end of the ear stud 16 from poking the ear.

[0023] Furthermore, a miniature cylinder 15 for moving the ear pin is provided on the machine frame 1 above the feeding port 14. After the ear pin 16 is polished, when the pneumatic rotary cylinder 6 drives the rotating rod 8 to rotate to the feeding port 14, the ear pin 16 may stick to it. At this time, the miniature cylinder 15 extends out. During the rotation, the ear pin 16 will touch the output end of the miniature cylinder 15 and thus loosen, causing the ear pin 16 to fall off.

[0024] In this embodiment, an automatic earring polishing device rotates one end of a rotating rod 8 with a picking tube 9 above the earring feeder 2 via a pneumatic rotary cylinder 6. The first cylinder 5 then operates, causing the pneumatic rotary cylinder 6 and the picking tube 9 to descend. Simultaneously, the air compressor 11 starts operating, using a vacuum generator 10 to create a vacuum in the picking tube 9, allowing it to pick up the earring 16. After the picking tube 9 picks up the earring 16, the first cylinder 5 raises the pneumatic rotary cylinder 6 and the picking tube 9. Then, the pneumatic rotary cylinder 6 rotates one end of the rotating rod 8 with the picking tube 9 above the polishing device 4. The first cylinder 5 then descends, inserting the earring 16 into the first fixing block 32. The ear needle 16 is placed in the needle-releasing hole 18 between the second fixed block 31. Simultaneously, the second cylinder 34 is activated, pushing the slider 33 to clamp the ear needle 16. Then, the motor 43 is activated, driving the rotating shaft 42 to rotate through the belt drive mechanism, thereby driving the grinding head 41 to grind the lower end of the ear needle 16. After grinding, with the cooperation of the first cylinder 5 and the pneumatic rotary cylinder 6, when the material picking tube 9 reaches the discharge port 14, the air compressor 11 stops working, the vacuum generator 10 stops vacuuming, and the ear needle 16 falls from the material picking tube 9 into the collection box 13 for collection. The entire movement process is simple and effective, quickly and efficiently picking up the ear needle 16 and placing it into the grinding device for grinding, thus realizing automated production and effectively improving production efficiency. This utility model provides an automatic ear needle grinding device that can grind ear needles in an orderly and rapid manner, effectively improving production efficiency. It is convenient to use and highly practical.
