Detailed implementation mode

[0018] The following further describes the present utility model with reference to specific embodiments in the accompanying drawings.

[0019] Refer to Figures 1-4 As shown, a pneumatic conveying mechanism for ear pins of the present utility model includes a workbench 1. A turntable 3 is rotatably arranged on the workbench 1. A plurality of support blocks 4 arranged in a surrounding manner are provided on the turntable 3. A positioning hole 5 is provided on the support block 4. A first column 6 is provided on one side of the workbench 1. A first support plate 7 is provided on the first column 6. An injection needle tube 8 aligned with the positioning hole 5 is provided on the first support plate 7. A second column 9 is provided on the workbench 1. A second support plate 10 is provided on the second column 9. A needle receiving tube 11 is provided on the second support plate 10. The injection needle tube 8 and the needle receiving tube 11 are connected and communicated through a rubber tube 12. Above the needle receiving tube 11, there is a pneumatic device 2 for picking up and injecting ear pins 18. By rotating the rotary pressing cylinder 21 of the pneumatic device 2, the material taking tube 22 is rotated and pressed down onto the ear pins 18 of the ear feeding machine 17. At this time, the dual-purpose pumping and vacuuming pump 24 is used for vacuum suction. Under the action of atmospheric pressure, the ear pins 18 enter the material suction hole 16, so that the material taking tube 22 adsorbs and picks up the ear pins 18. After rotating 90° by the rotary pressing cylinder 21, the material taking tube 22 is located above the needle receiving tube 11. At this time, the second slide cylinder 14 starts to work, pushing the second support plate 10 upward, so that the material taking tube 22 is inserted into the needle receiving tube 11. At the same time, the first slide cylinder 13 works, pushing the first support plate 7 downward, so that the injection needle tube 8 is inserted into the positioning hole 5. Then, the dual-purpose pumping and vacuuming pump 24 is used for jetting air. Through the air pressure, the ear pins 18 are first jetted into the needle receiving tube 11, and then reach the injection needle tube 8 along the rubber tube 12, and quickly enter the positioning hole 5 through the injection needle tube 8. The whole movement process is simple and effective, quickly and effectively automatically conveying the ear pins 18 into the positioning hole 5 for the next process, thus realizing automated production and effectively improving production efficiency.

[0020] Specifically, the pneumatic device 2 includes a rotary pressing cylinder 21, a material taking pipe 22, and a dual-purpose pumping and blowing vacuum pump 24. The rotary pressing cylinder 21 is arranged at the front end of the earring needle feeding machine 17. The material taking pipe 22 is installed at the output end of the rotary pressing cylinder 21. The material taking pipe 22 is communicated with the dual-purpose pumping and blowing vacuum pump 24 through an air pipe 23. The rotary pressing cylinder 21 has a rotation angle of 90°. The outer diameter of the material taking pipe 22 is equal to the inner diameter of the needle receiving pipe 11. The rotary pressing cylinder 2 rotates 90°, rotates and presses the material taking pipe 22 onto the earring needle 18 of the ear feeding machine 17. Under the action of the dual-purpose pumping and blowing vacuum pump 24, the small-volume earring needle 18 can be adsorbed to achieve precise picking of the earring needle 18. After picking, it rotates 90°, aligns with the needle receiving pipe 11 and is connected, and then jets air through the dual-purpose pumping and blowing vacuum pump 24, so as to spray the earring needle 18 along the rubber tube 12 into the positioning hole 5, realizing the functions of automatic picking and conveying.

[0021] Preferably, a second sliding table cylinder 14 is provided between the second support plate 10 and the second column 9. The second sliding table cylinder 14 is installed on the second column 9. The output end of the second sliding table cylinder 14 is connected to the second support plate 10. When the material taking pipe 22 is located above the needle receiving pipe 11, the second sliding table cylinder 14 starts to work at this time, pushing the second support plate 10 to move upward, so that the material taking pipe 22 is inserted into the needle receiving pipe 11, preventing air pressure leakage and ensuring that the earring needle 18 can smoothly fall into the needle receiving pipe 11.

[0022] Further, a first sliding table cylinder 13 is provided between the first column 6 and the first support plate 7. The first sliding table cylinder 13 is installed on the first column 6. The output end of the first sliding table cylinder 13 is connected to the first support plate 7. The first sliding table cylinder 13 works, pushing the first support plate 7 to move downward, so that the injection needle pipe 8 is inserted into the positioning hole 5, preventing air pressure leakage and ensuring that the earring needle 18 can smoothly fall into the positioning hole 5.

[0023] Further, a ventilation hole 15 and a material suction hole 16 are opened in the material taking pipe 22. The material suction hole 16 is in clearance fit with the head of the earring needle 18. The diameter of the ventilation hole 15 is smaller than the diameter of the material suction hole 16, thus forming a step. While ensuring that the stud 18 will be adsorbed into the material suction hole 16 of the material taking pipe 22, it prevents passing through the ventilation hole 15, thereby ensuring that the material taking pipe 22 can firmly adsorb the stud 18 and realizing the picking function.

[0024] When the pneumatic conveying mechanism of an auricular needle in this embodiment is in use, the rotating and pressing cylinder 21 of the pneumatic device 2 rotates, rotating and pressing the material taking pipe 22 onto the auricular needle 18 of the auricular needle feeding machine 17. At this time, the pumping and blowing dual-purpose vacuum pump 24 is used to evacuate and suck air. Under the action of atmospheric pressure, the auricular needle 18 enters the material suction hole 16, so that the material taking pipe 22 adsorbs and picks up the auricular needle 18. After the rotating and pressing cylinder 21 rotates 90°, the material taking pipe 22 is located above the needle receiving pipe 11. At this time, the second sliding table cylinder 14 starts to work, pushing the second support plate 10 upward, so that the material taking pipe 22 is inserted into the needle receiving pipe 11. At the same time, the first sliding table cylinder 13 works, pushing the first support plate 7 downward, so that the injection needle pipe 8 is inserted into the positioning hole 5. Then, the pumping and blowing dual-purpose vacuum pump 24 is used to blow air. Through the air pressure, the auricular needle 18 is first sprayed into the needle receiving pipe 11, and then reaches the injection needle pipe 8 along the rubber tube 12, and quickly enters the positioning hole 5 through the injection needle pipe 8. The whole movement process is simple and effective, quickly and effectively automatically conveying the auricular needle 18 into the positioning hole 5 for the next process, thus realizing automatic production and effectively improving production efficiency. The pneumatic conveying mechanism of an auricular needle of the present utility model can convey auricular needles orderly and quickly, effectively improving production efficiency, and has the characteristics of wide application range and strong practicability.

[0025] The above are only the preferred embodiments of the present utility model. It should be pointed out that for those skilled in the art, without departing from the structure of the present utility model, several deformations and improvements can be made, which will not affect the implementation effect of the present utility model and the practicability of the patent.
