Referring to fig. 1, an embodiment of the present invention provides a metal nut feeding mechanism 5, including a vibration plate 51 and a conveying pipe 52 connected to a tail end of the vibration plate 51, wherein a hopper 511 is disposed at a central position of the vibration plate 51, a spiral conveying track 5111 is disposed at a bottom of the hopper 511 in an upward extending manner, a sorting track 5112 is connected to a tail end of the spiral conveying track 5111, a screening pipe 5113 is connected to a tail end of the sorting track 5112, and the screening pipe 5113 is connected to the conveying pipe 52. The metal nuts 10 placed in the hopper 511 continuously move forward along the spiral conveying track 5111, and then are arranged into the sorting track 5112 one by one, the metal nuts 10 entering the sorting track 5112 are in different directions, some metal nuts 10 have central holes facing the extending direction of the sorting track 5112, and some metal nuts 10 are tilted upwards; and only the metal nut 10 having a central hole toward the extension direction of the sorting track 5112 is correct. When the metal nuts 10 are moved to the screening tube 5113, only the metal nuts 10 having the central holes facing the extension direction of the sorting track 5112 can smoothly enter the screening tube 5113, and the metal nuts 10 facing the other direction are blocked by the entrance of the screening tube 5113, thereby falling back into the screw conveying track 5111. Finally, the metal nuts 10 entered into the screen pipe 5113 are conveyed to the next process mechanism through the conveying pipe 52.

Specifically, in the embodiment, the screening pipes 5113 and the conveying pipes 52 have the same pipe diameter, and the pipe diameters of the screening pipes 5113 and the conveying pipes 52 are slightly larger than the outer diameter of the metal nut 10, so that the metal nut 10 can smoothly screen the pipes 5113 and the conveying pipes 52, and the orientations of the pipes in the screening pipes 5113 and the conveying pipes 52 will not change.

Specifically, the sorting track 5112 is integrally arc-shaped, and an upper portion of the sorting track 5112 is open to form an upper opening 51121, as shown in fig. 2, some of the metal nuts 10 tilting upward can fall out of the upper opening 51121 in the process that the metal nuts 10 continuously move forward.

In the present embodiment, the vibrating plate 51 having the combination of the sorting track 5112 and the screening pipe 5113 is used to perform feeding sorting and orientation screening on the metal nuts 10, so that the metal nuts 10 can enter the conveying pipe 52 in a correct orientation one by one, thereby preventing occurrence of phenomena such as disordered sorting of the metal nuts 10, wrong orientation of the metal nuts 10, blockage of the conveying pipe 52, and the like, and facilitating subsequent accurate implantation of the metal nuts 10 into the plastic strip 20, as shown in fig. 7, which is beneficial to improving the implantation efficiency and accuracy.

The metal nut feeding mechanism 5 provided in this embodiment is particularly suitable for a full-automatic metal nut implanting machine to complete the feeding operation of the metal nut 10, as shown in fig. 3.

The full-automatic metal nut implanting machine of this embodiment includes a machine 1, at least one carrying tray 2 disposed on the machine 1, a lifting driving mechanism 3 erected on the machine 1, a nut implanting mechanism 4 connected to the lifting driving mechanism 3 and located above the carrying tray 2, and the metal nut feeding mechanism 5 connected to the nut implanting mechanism 4. The metal nut feeding mechanism 5 feeds the metal nuts 10 to the nut implanting mechanism 4, the lifting driving mechanism 3 drives the metal nut feeding mechanism 5 to wholly move up and down, so that the nut implanting mechanism 4 implants the metal nuts 10 into the plastic strips 20 on the carrying disc 2 one by one, as shown in fig. 7, automatic implanting operation of the metal nuts 10 is completed, and compared with manual operation, the automatic implanting device is high in automation degree and obviously improves working efficiency.

In this embodiment, as shown in fig. 4 and fig. 5, the nut implanting mechanism 4 includes a horizontal mounting substrate 41 disposed on the side of the lifting driving mechanism 3, a blanking base 42 connected to the lower end of the horizontal mounting substrate 41, a hollow blanking heating tube 43 disposed below the blanking base 42, a nut positioning component 44 disposed on the blanking base 42, and a blanking control component 45 slidably disposed on the side of the blanking base 42, wherein a longitudinal blanking chamber 421 located between the nut positioning component 44 and the hollow blanking heating tube 43, and a horizontal moving chamber 422 for movably inserting one end of the blanking control component 45 and communicating with the longitudinal blanking chamber 421 are respectively formed in the blanking base 42, and the conveying pipe 52 of the metal nut feeding mechanism 5 is communicated with the side of the longitudinal blanking chamber 421. The metal nuts 10 conveyed by the metal nut feeding mechanism 5 enter the longitudinal blanking chamber 421 one by one from the side, and only one metal nut 10 enters the longitudinal blanking chamber 421 at the same time. After the metal nuts 10 enter the longitudinal blanking cavity 421, the metal nuts 10 are controlled by the blanking control assembly 45 to fall into the hollow blanking heating tube 43 one by one; then, the metal nut 10 enters the mounting hole of the plastic strip 20 on the carrying disc 2 through the hollow blanking heating tube 43; next, the nut positioning assembly 44 positions the metal nut 10; since the metal nut 10 falls through the hollow blanking heating tube 43, in the falling process, the hollow blanking heating tube 43 transfers heat to the metal nut 10, the temperature of the metal nut 10 entering the mounting hole of the plastic strip 20 rises, the plastic part on the side wall of the mounting hole is melted, and the metal nut 10 is adhered to the inner wall of the mounting hole.

Specifically, as shown in fig. 4, the blanking control assembly 45 includes a transverse pushing driving cylinder 451 transversely disposed on the transverse mounting substrate 41, an L-shaped guide plate 452 longitudinally disposed and connected to an end portion of an output shaft of the transverse pushing driving cylinder 451, a slide rail 453 disposed on a lower end surface of the transverse mounting substrate 41, a slide block 454 disposed on the slide rail 453 and connected to the L-shaped guide plate, a connecting block 455 connected to a lower end of the L-shaped guide plate 452, and a blanking control block 456 connected to an end portion of the connecting block 455 and inserted into the transverse movable chamber 422, wherein a blanking opening 4561 is formed on the blanking control block 456. The transverse pushing driving cylinder 451 provides a transverse driving force to drive the L-shaped guide plate 452 to transversely and linearly slide along the slide rail 453, so that the connecting block 455 drives the blanking control block 456 to slide in the transverse movable cavity 422, so that the blanking port 4561 on the blanking control block 456 is switched between being aligned with the longitudinal blanking cavity 421 and being away from the longitudinal blanking cavity 421. Specifically, as shown in fig. 5, in an initial state, the blanking port 4561 is staggered from the longitudinal blanking cavity 421, and the metal nut 10 cannot fall from the blanking port 4561 and enter the hollow blanking heating tube 43; when the blanking control block 456 slides leftwards to align the blanking opening 4561 with the longitudinal blanking cavity 421, as shown in fig. 6, the metal nut 10 can fall from the blanking opening 4561 into the hollow blanking heating tube 43; when the blanking control block 456 slides backward to the right so that the blanking opening 4561 is offset from the longitudinal blanking chamber 421, the metal nut 10 cannot fall from the blanking opening 4561 into the hollow blanking heat-generating tube 43, as shown in fig. 5.

In the present embodiment, the dropping motion of the metal nut 10 is controlled by controlling the sliding of the dropping control block 456 from side to side, thereby achieving the purpose of sequentially dropping and implanting the metal nuts 10 one by one.

Specifically, as shown in fig. 3 and 5, the nut positioning assembly 44 includes a lifting pushing cylinder 441, and a nut positioning thin rod 442 connected to the lower end of the output shaft of the lifting pushing cylinder 441 and located right above the longitudinal blanking chamber 421. When the metal nut 10 falls through the blanking port 4561, the lifting push cylinder 441 provides downward driving force to drive the nut positioning thin rod 442 to move downwards to enter the longitudinal blanking cavity 421 and closely follow the back of the metal nut 10, so that the next metal nut is blocked, and the next metal nut is prevented from falling along with the previous metal nut; when the metal nut 10 enters the plastic strip 20 on the carrying disc 2 through the hollow blanking heating tube 43, the nut positioning thin rod 442 also passes through the blanking port 4561, finally penetrates out of the hollow blanking heating tube 43, is inserted into the central hole of the metal nut 10, and positions the metal nut 10, so that the metal nut 10 can be accurately adhered to the mounting hole of the plastic strip 20, and therefore the accuracy of the position of the metal nut 10 implanted into the plastic strip 20 is improved.

In order to make the hollow blanking heating tube 43 generate heat and transmit the temperature to the metal nut 10, the hollow blanking heating tube 43 is connected with a plurality of heating wires 46 in the embodiment. In order to facilitate the hollow blanking heating tube 43 to smoothly transfer heat to the metal nut 10, preferably, the hollow blanking heating tube 43 is made of a metal material. Meanwhile, it should be noted that, since the plastic can be partially melted by heating, as long as the metal nut 10 has heat higher than normal temperature, the plastic on the inner wall of the mounting hole of the plastic strip 20 can be partially melted, and as long as the plastic is partially and slightly melted, the metal nut 10 can be stuck.

The embodiment adopts a hot melting mode, and the metal nuts 10 entering the plastic strip 20 are adhered and fixed to prevent the metal nuts 10 from shifting, so that the product quality is guaranteed.

The lifting driving motor 32 provides lifting driving force to drive the lifting screw 33 to move up and down, and the lifting screw sleeve 34 moves up and down along with the lifting driving force, so that the whole nut implanting mechanism 4 is driven to do lifting movement, and the nut implanting mechanism 4 can complete the implanting operation of the metal nut 10.

In order to facilitate the positioning of the plastic strip 20 on the carrier disc 2, as shown in fig. 3 and 7, the carrier disc 2 is formed with a plurality of carrier grooves 21 for the plastic strip 20 to be inserted into.

In this embodiment, the full-automatic metal nut implanting machine further includes a translation driving mechanism 6 erected on the machine table 1, as shown in fig. 3, the translation driving mechanism 6 includes a frame 61 erected on the machine table 1, a translation driving motor disposed in the frame 61, a connecting seat 63 respectively connected to an end of an output shaft of the translation driving motor and the lifting driving mechanism 3, a translation guiding seat 64 connected to the connecting seat 63, and a translation guiding drag chain 65 disposed on the frame 61 and connected to the translation guiding seat 64.
