A base 31 is fixed on the servo motor 30. A through hole 310 is defined in the middle of the base 31. The rotating shaft 300 of the servo motor 30 is A through hole 310 is defined in the base 31. The base 31 is provided with a ring groove 312. The ring groove 311 is formed in the side wall of the base 31. The position of the feed slot 312 is provided with an electric eye hole 313 corresponding to the opposite direction (one hundred and eighty degrees) of the electric eye hole 313. There is a discharge hole 314 which is aligned with one of the receiving grooves 20 of the nut punching machine 2, and a turntable 32 is attached to the base 31 and rotatable on the base 31. A groove 320 corresponding to the rotating shaft 300 is disposed in the middle of the bottom of the rotating plate 32. A positioning slot 321 is defined in the groove 301 corresponding to the rotating shaft 300. The groove 320 corresponds to the rotating shaft 300. The bottom of the screw hole 302 is provided with a through hole 322. The bottom surface of the turntable 32 is oppositely disposed with two receiving slots 323. The receiving slot 323 is connected to the side wall surface of the turntable 32, and one of the receiving slots is received. The 323 is aligned with the receiving slot 312 of the base 31. The height of the receiving slot 323 is slightly larger than the thickness of the spacer 11. The receiving slot 323 is provided with a through hole 324. The inner wall surface of the through hole 324 is provided with a light guiding groove 325, wherein the light guiding groove 325 of the through hole 324 is aligned with the electric eye hole 313 of the base 31, and a plurality of screwing elements 33 are respectively extended on the rotating plate. The hole 322 of the 32 is inserted into the screw hole 302 of the rotating shaft 300, and the disk surface of the bottom of the rotating plate 32 is disposed on the ring groove 311 of the base 31. Wherein the lower eyelet 313 over the light guide opposite to a through hole 324 of the groove 325 of the turntable 32 An electric eye sensor 34 is disposed, and a push rod 35 is disposed above the discharge hole 314 of the base 31, and a gasket vibrating feeder 4 is disposed on the outer side of the automatic feeding device 3 (as shown in the second figure), The outer end of the feed rail 40 of the shim vibrating feeder 4 is aligned with the feed slot 312 of the base 31. The feed rail 40 is provided with a guide slot 400, and the outer end of the feed rail 40 is disposed. There is a pressing rod 401, and the end of the pressing rod 401 is located on the guiding groove 400 for holding the gasket 11 to the limit position. Thus, it is a gasket automatic feeding device for the anti-loose nut.

When in use, please refer to the second to seventh figures, the gasket 11 is placed in the gasket vibrating feeder 4, and the gaskets 11 are arranged one by one by the gasket vibrating feeder 4 to be transported to the mat through the feeding rail 40. In the automatic feeding device 3 (as shown in the second, fourth and fifth figures), the outer end of the feeding rail 40 via the gasket vibrating feeder 4 is aligned with the feeding slot of the base 31 of the automatic feeding device 3 of the gasket. At the position 312, the spacer 11 is pushed into the receiving slot 323 of the turntable 32 by the feed slot 312 of the base 31. Since the height of the receiving slot 323 is slightly larger than the thickness of a spacer 11, Only one spacer 11 can be provided, and no spacer 11 is inserted. When the spacer 11 is pushed into one of the slots 32 of the turntable 32, the electric eye sensor 34 is used. The light is projected into the ring groove 311 of the base 31 by the electric eye hole 323 of the base 31. If the spacer 11 has entered the receiving slot 323 of the turntable 32, the spacer 11 blocks the light source of the electric eye sensor 34. The light source of the electric eye sensor 34 cannot be projected by the light guide groove 325 of the turntable 32, and the electric eye sensor 34 above the turntable 32 cannot receive the light source. It indicates that the spacer 11 has been positioned, the servo motor 30 is actuated, and the rotating shaft 300 is rotated. The latch 301 of the rotating shaft 300 drives the turntable 32 to rotate at 180 degrees, and the receiving slot of the built-in spacer 11 is provided. The 323 is rotated to the opposite side and is opposite to the discharge hole 314 of the base 31. The spacer 11 in the receiving slot 323 is dropped from the discharge hole 314 of the base 31 into the discharge hole 314 located at the base 31. In the chamber 100 of the nut body 10, in order to ensure that the gasket 11 in the receiving groove 323 of the turntable 32 can be surely dropped from the discharge opening 314 of the base 31 into the nut placed on the nut punching machine 2 below. The body 10 is in the chamber 100, so it is aligned with the turntable 32. The push rod 35 above the through hole 324 is downwardly actuated and inserted into the through hole 324 (as shown in FIG. 6), so that the spacer 11 in the receiving slot 323 can be surely dropped from the discharge hole 314. In the chamber 100 of the nut body 10, another receiving slot 323 on the other turntable 32 is rotated to the outer end of the feed rail 40 corresponding to the spacer vibrating feeder 4, and as described above, The other gasket 11 is sent to the chamber 100 of the nut body 10 via the gasket automatic feeding device 3 for punching of the nut punching machine 2; and when the gasket 11 is in the feeding rail of the vibrating feeder 4 via the gasket When the 40 is transported into the automatic feeding device 3 of the gasket, if the gasket 11 fails to fully enter the receiving slot 323 of the turntable 32 (as shown in FIG. 7), the light source of the lower eye sensor 34 is The electric eye hole 313 of the base 31 is projected upward through the light guiding groove 325 of the turntable 32, and is received by the upper electric eye sensor 34. At this time, the servo motor 30 does not act, and the gasket 11 needs to be completely inserted into the receiving cut. In the slot 323, after the light source of the electric eye sensor 34 is shielded, the servo motor 30 can be actuated again, and the turntable 32 is rotated to complete the pad. The automatic conveying of the sheet 11 is such that, by the arrangement of the automatic feeding device 3 of the gasket of the present invention, the single gaskets 11 can be automatically fed into the respective nut bodies 10 of the nut punching machine 2 for the purpose of The nut punching machine 2 presses the nut body 10, and the gasket 11 of the present invention automatically feeds the material very conveniently and quickly, and the gasket 11 only conveys one to the nut body 10 at a time, and does not overlap each other. Produced to ensure the production yield of the product and effectively improve production efficiency.

In view of the above, the present invention has achieved the intended use and efficacy, and is more desirable and practical than the prior art, but the above embodiments are only specifically described for the preferred embodiment of the present invention. The present invention is not intended to limit the scope of the invention, and all other equivalents and modifications may be included in the scope of the invention covered by the invention.
