When fixing the button on the sewing machine 52, the telescopic end of the third electric telescopic rod 50 pushes the top platform 51 to move upward, so that the clothing on the top platform 51 moves to the sewing position for sewing. Then, the telescopic end of the third electric telescopic rod 50 drives the top platform 51 to move downward, and the coiling box 10 continues to convey the button.

[0025] In summary, when using the hanging button positioning feeder, put the button into the vibrating feeder 2, and then the vibrating feeder 2 guides the button to the top of the bottom rail 3, and moves the button under the top plate 56. At this time, the first pump 33 pumps out the gas inside the gas tank 34, and then discharges the gas into the first rotary joint 32 through the other end of the first pump 33, and then inputs the gas into the expansion belt 14 through the second pipeline 58, so that the expansion belt 14 expands. One end of the expanded expansion belt 14 enters the hole in the button, and then the expanded expansion belt 14 contacts the bottom of the pressure plate 57. The piezoelectric sensor installed inside the pressure plate 57 detects the position of the pressure point to check whether it is at the required position. Then, the output end of the second motor 44 drives the winding box 10 to rotate, so that the winding box 10 drives the button to rotate through the friction belt 15, and adjusts the position of the threading hole on the button until the position of the pressure point corresponds to the required position. Then, the first pump 33 starts, and the first pump 33 pumps out the gas inside the first rotary joint 32, the second pipeline 58 and the expansion belt 14, and then discharges the gas into the gas tank 34 for collection and storage; Make the expansion belt 14 contract. Then, the output end of the first motor 37 drives the first winding roller 12 to rotate, so that the first winding roller 12 winds the first connecting belt 13 and the expansion belt 14. At the same time, the output end of the second servo motor 39 drives the driving gear 40 to drive the second winding roller 18 to rotate, so that the second winding roller 18 releases the adsorption belt 17 and the third connecting belt 19, and makes the adsorption belt 17 located under the button. Then, the electromagnet 25 starts, and a mutually repulsive magnetic field is generated between the two vertical electromagnets 25, so that the electromagnet 25 pushes the annular plate 24 and the top column 28 to move upward. If the pressure sensor 30 on the top column 28 detects a pressure value, it proves that there is no button above the first rotary joint 32. At this time, the top end of the plug 26 is inserted into the first rotary joint 32 to seal the inside of the first rotary joint 32. If the pressure sensor 30 on the top column 28 does not detect a pressure value, it proves that there is a button above the first rotary joint 32. At this time, the electromagnet 25 is turned off, and the mutually repulsive magnetic field between the two vertical electromagnets 25 disappears. At this time, the support spring 27 pushes one end of the annular plate 24 and the plug 26 out of the suction hole 22, so that the inside of the suction hole 22 is opened; Then, the second pump 35 extracts the air inside the hollow cavity 21 through the second rotary joint 36 and the first pipeline 20, so as to generate suction force inside the suction holes 22, adsorb the top of the adsorption belt 17 to the bottom of the button, and adsorb the bottom of the adsorption belt 17 to the top of the winding box 10. Then, the telescopic end of the second electric telescopic rod 48 drives the fixed block 45, the second motor 44 and the winding box 10 to move downward. Then, the output end of the third motor 46 drives the rotating block 47, the second electric telescopic rod 48 and the winding box 10 to move below the sewing machine 52. Then, the telescopic end of the fourth electric telescopic rod 54 pushes the clamping blocks 55 to move, so that the two clamping blocks 55 clamp the outside of the knob. At this time, the other end of the second pump 35 inhales the outside air through the filter head, and then inputs it into the hollow cavity 21 through the second rotary joint 36 and the first pipeline 20, so that the suction force inside the hollow cavity 21 and the suction holes 22 disappears, and the adsorption of the button is released. Then, the output end of the first motor 37 drives the first winding roller 12 to rotate back to its original position, so that the first connecting belt 13 and the expansion belt 14 are released. At the same time, the output end of the second servo motor 39 drives the driving gear 40 to rotate, so that the driving gear 40 drives the second winding roller 18 to wind the third connecting belt 19, the adsorption belt 17 and the second connecting belt 16, so that the expansion belt 14 is located above the winding box 10. At the same time, the output end of the third motor 46 drives the rotating block 47 to rotate, so that the rotating block 47 drives the second electric telescopic rod 48 and the winding box 10 to rotate below the bottom rail 3. Then, the telescopic end of the second electric telescopic rod 48 pushes the top of the winding box 10 into the positioning groove 9 for the subsequent feeding work of the button.

[0026] The above is only a preferred specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution and inventive concept of the present invention, makes equivalent substitutions or changes, and all should be covered by the protection scope of the present invention.
