A large number of ear needles 14 are stored in the storage tank 7, and then the drum motor 24 is started to drive the outer gear drum 24 to rotate. When the outer gear drum 24 rotates, the ear needles are scooped into the V-shaped groove 12 of the needle feeding track 6 by the arc-shaped spoon plate 22. Under the action of gravity, the smaller ends of some ear needles will fall into the through groove 13, and the larger ends will be stuck on the V-shaped groove 12, and the brush is rotated by the servo motor 41 43 makes a reciprocating motion of left and right swing, so as to clean up the ear needles 14 that have not fallen into the through slots 13 to prevent them from being blocked in the front, so that the ear needles 14 are arranged in order on the needle feeding track 6 and transported outward under the vibration of the vibration motor 31. The ear needles 14 follow the through slots 13 into one of the receiving slots 9, and the stepper motor rotates the discharge plate 10, and the next receiving slot 9 is aligned with the through slot 13 to realize the discharge of the next ear needle 14. When the stepper motor rotates the ear needle to the front end, the manipulator removes the ear needle 14 on the receiving slot 9, and the photoelectric sensor 11 senses that there is no ear needle in the receiving slot 9. When there are ear needles, the signal is transmitted to the controller, and the controller controls the stepper motor to rotate. The stepper motor and the photoelectric sensor 11 cooperate to realize the repeated material taking of the receiving slot 9, so that the ear needles 14 are automatically and neatly arranged for loading, which is convenient for the robot to take, thereby realizing fully automated loading and effectively improving the overall production efficiency. There are four receiving slots 9, which are evenly distributed on the discharge tray 10, so that the stepper motor can discharge one ear needle 14 when it rotates 90°. When the ear needle 14 rotates 180° under the action of the discharge tray 10, it comes to the front end to facilitate the robot to take, thereby realizing automatic loading.

[0021] Specifically, a V-shaped groove 12 is opened at the upper end of the needle feeding track 6, and a through groove 13 is opened at the lower end of the needle feeding track 6. The V-shaped groove 12 is connected with the through groove 13, and the ear needles 14 are arranged on the through groove 13. The V-shaped groove 12 is convenient for accommodating more ear needles 14 that fall from the arc-shaped spoon plate 22, so that the ear needles 14 can fall into the through groove 13 in an orderly manner, thereby realizing arrangement and transportation.

[0022] Preferably, the rotary feeding mechanism 2 includes a mounting base 23, an external gear drum 21, a drum motor 24 and a plurality of arc-shaped spoon plates 22. The plurality of arc-shaped spoon plates 22 are evenly installed on the inner ring of the external gear drum 21. The external gear drum 21 is rotatably installed on the mounting base 23. The mounting base 23 is installed in the housing 1. The output end of the drum motor 24 is engaged with the external gear ring of the external gear drum 21 through a gear. The output end of the drum motor 24 drives the external gear drum 24 to rotate through the gear. When the external gear drum 24 rotates, the arc-shaped spoon plates 22 are used to scoop the ear pins into the V-shaped groove 12 of the needle feeding track 6, so as to realize the feeding of the small-sized ear pins 14.

[0023] Further, a photoelectric sensor 11 for detecting whether there is an ear pin 14 in the receiving groove 9 is provided at the front end of the discharging platform 8, which is used to detect whether the ear pin 14 is smoothly taken away by the manipulator. After being taken away, the stepping motor is controlled to work, so that the working connectivity is better and it is beneficial to improve the working efficiency.

[0024] Further, the needle feeding track 6 is arranged obliquely from inside to outside. The needle feeding track 6 passes through the rotary feeding mechanism 2. Under the action of the inclination, it is convenient for the ear pins 14 to slide to the lower place, so as to realize automatic discharging.

[0025] Further, the vibration device 3 includes a vibration motor 31 and a shock absorber 32. The vibration motor 31 is installed at the middle position of the bottom of the needle feeding track 6, and the shock absorber 32 is installed at both ends of the needle feeding track 6. Under the action of the shock absorber 32, the speed of the ear pins 14 moving outwards is accelerated, so that the ear pins 14 can be smoothly arranged and conveyed along the needle feeding track 6 in an orderly manner.

[0026] Further, the cleaning device 4 includes a rotating shaft 42, a brush 43 and a servo motor 41. The brush 43 is rotatably installed on the housing 1 through the rotating shaft 42. The servo motor 41 is installed in the housing 1. The output end of the servo motor 41 is connected to the rotating shaft 42. The brush 43 is arranged above the needle feeding track 6. The servo motor 41 rotates the brush 43 to make a reciprocating motion of swinging left and right, so as to realize cleaning most of the ear pins 14 that have not fallen into the through groove 13, and prevent the ear pins 14 from discharging before being arranged neatly, resulting in blockage of the equipment.

[0027] When the feeding device for auricular needles in this embodiment is in use, a large number of auricular needles 14 are stored in the storage tank 7. Then, the roller motor 24 is started to drive the external-tooth roller 24 to rotate. When the external-tooth roller 24 rotates, the arc-shaped spoon plate 22 is used to scoop the auricular needles into the V-shaped groove 12 of the needle feeding track 6. Under the action of gravity, the smaller ends of some auricular needles will fall into the through groove 13, and the larger ends are stuck on the V-shaped groove 12. The servo motor 41 rotates the brush 43 to make a reciprocating left-right swinging motion, so as to sweep down the auricular needles 14 that have not fallen into the through groove 13 and prevent blockage in the front, so that the auricular needles 14 are arranged in order on the needle feeding track 6 and are conveyed outward under the vibration of the vibration motor 31. The auricular needles 14 enter one of the receiving grooves 9 along the through groove 13. The discharging disc 10 is rotated by the stepping motor, and the next receiving groove 9 is aligned with the through groove 13 to realize the discharging of the next auricular needle 14. When the stepping motor rotates the auricular needle to the front end, the auricular needle 14 on the receiving groove 9 is taken away by the manipulator. When the photoelectric sensor 11 senses that there is no auricular needle in the receiving groove 9, it sends a signal to the controller, and the controller controls the stepping motor to rotate. Through the cooperation of the stepping motor and the photoelectric sensor 11, the receiving groove 9 repeatedly takes materials, so as to realize the full-automatic and neat arrangement of the auricular needles 14 for feeding, which is convenient for the manipulator to pick up, thus realizing full-automatic feeding and effectively improving the overall production efficiency. The feeding device for auricular needles of the present invention can quickly arrange the needles neatly, which is convenient for the manipulator to pick up, effectively improves the production efficiency, and has the characteristics of convenient use and strong practicability.

[0028] The above are only the preferred embodiments of the present invention. It should be pointed out that for those skilled in the art, without departing from the structure of the present invention, several deformations and improvements can be made, which will not affect the implementation effect of the present invention and the practicability of the patent.
