Obviously, the described implementation mode is a part of the implementation mode of the utility model, not all of the implementation modes. Based on the implementation mode in the utility model, all other implementation modes obtained by ordinary technicians in this field without making creative work are within the scope of protection of the utility model. Therefore, the following detailed description of the implementation mode of the utility model provided in the drawings is not intended to limit the scope of the utility model for which protection is sought, but merely represents the selected implementation mode of the utility model. Based on the implementation mode in the utility model, all other implementation modes obtained by ordinary technicians in this field without making creative work are within the scope of protection of the utility model.

[0022] Depend on Figures 1 to 5As shown, the embodiment of the utility model provides a screw conveying and transferring device, including a guide rail conveying mechanism 1, a separation mechanism 2 and a clamping and transferring mechanism 3, wherein the separation mechanism 2 is provided with a transfer groove suitable for receiving a screw 5, and the transfer groove 10 can be connected to the output end of the guide rail conveying mechanism 1 to receive the screw 5 conveyed by the guide rail conveying mechanism 1; the separation mechanism 2 is used to transfer the received screw 5 from the output end port of the guide rail conveying mechanism 1 to the lower part of the output end of the clamping and transferring mechanism 3; and further includes an ejection assembly 6, which is arranged below the transfer groove 10 to eject the head end of the screw 5 from the transfer groove 10, so as to facilitate the clamping and transferring mechanism 3 to clamp and transfer the screw 5. The screws 5 are conveyed one by one in a queue to the transfer groove 10 of the guide rail conveying mechanism 1, and the separation mechanism 2 isolates the screws 5 by moving the position of the transfer groove 10, and then the screws 5 located in the transfer groove 10 are ejected out of the rod end by the ejection assembly 6, so that the head end of the screws 5 can be conveniently clamped by the clamping and transferring mechanism 3, and then transferred to the next process.

[0023] Preferably, the guide rail conveying mechanism 1 includes a straight vibrator 6 and a conveying track 7, and the conveying track 7 is arranged above the straight vibrator 6 to convey the screws 5 toward the direction of the separation mechanism 2. In this embodiment, the conveying track 7 is a straight track channel suitable for arranging the screws 5 individually, so that the screws 5 can be conveyed to the transfer groove 10 one by one through the straight vibrator 6.

[0024] In this embodiment, a plurality of conveying tracks 7 can be provided on a straight vibrator 6, and a plurality of transfer grooves 10 are also provided on the corresponding separation mechanism 2, so that a plurality of screws 5 can be separated at one time.

[0025] Preferably, the separation mechanism 2 includes a first movable table 8 and a transfer table 9, wherein the transfer table 9 is arranged at the output end of the first movable table 8, and the transfer slot 10 is arranged at one end side of the transfer table 9 close to the guide rail conveying mechanism 1. In this embodiment, the first movable table 8 is a combination of a cylinder and a slide rail slide table, which is connected to the transfer table 9 to control the transfer table 9 to move back and forth in the horizontal direction perpendicular to the conveying track. When the transfer slot 10 is aligned with the output port of the conveying track 7, it can receive and receive the screw 5. The transfer table 9 moves, so that the screw 5 in the transfer slot 10 is isolated, and the output port of the conveying track 7 is blocked by the end side of the transfer table 9, so that the screw 5 can be separated from other screws 5 in the queue after entering the transfer slot 10.

[0026] Furthermore, it also includes a connecting platform 11, which is arranged between the transfer platform 9 and the guide rail conveying mechanism 1. A connecting groove 12 suitable for the screw 5 to pass through is arranged on the connecting platform 11. The two ends of the connecting groove 12 correspond to the unmoved transfer groove 10 and the output port of the conveying track 7 respectively, playing a transition role between the two, and can prevent the vibration generated by the straight vibrator 6 from affecting the separation mechanism 2. At the same time, the side end of the transfer platform 9 is close to the side end of the connecting platform 11, so that when the transfer groove 10 moves, the side end of the connecting platform 11 can serve as a blockage for the side opening of the transfer groove 10.

[0027] Preferably, the transfer groove 10 is set through the transfer platform 9; the ejection assembly 6 includes a support block 13, a roller 14 and a screw moving assembly 15, the roller 14 is rotatably connected to one side end of the support block 13 through a rotating shaft, and the support block 13 is fixed on the output end of the screw moving assembly 15. In this embodiment, the support block 13 and the connecting platform 11 are provided with a protruding support block 13, and a slide rail is provided with the connecting platform 11 for sliding connection, as a problem of limiting the radial rotation of the screw moving assembly 15 when it acts. This is a conventional setting and will not be elaborated here; the roller 14 is set below the transfer groove 10. The roller 14 is located directly below the path of the transfer groove 10 when it moves. When the screw 5 moves, the exposed part below abuts against the roller 14, and moves upward along the roller 14 when moving, so that the head end of the screw 5 is exposed to facilitate clamping. It should be noted that the diameter of the roller 14 and the position of the bottom end of the screw 5, when the two are in contact, are preferably higher than the outer peripheral part above the radius of the roller 14, so as to avoid the screw 5 being damaged by the incorrect force position during contact. If necessary, the roller 14 can be further equipped with a rotating motor to drive the rotation, so as to better lift the screw 5. Preferably, the height of the roller 14 is controlled by the screw moving assembly 15 as the lifting support block 13, so as to make adjustments. The screw control is more precise and can also be adjusted for screws 5 of different models.

[0028] Preferably, the clamping and transferring mechanism 3 includes a second moving platform 16, a lifting cylinder 17, a connecting block 18 and a parallel cylinder clamp 19. The second moving platform 16 is horizontally arranged above the separation mechanism 2. The lifting cylinder 17 is fixed on the output end of the second moving platform 16. The connecting block 18 is fixedly connected between the output end of the lifting cylinder 17 and the parallel cylinder clamp 19. In this embodiment, the second moving platform 16 is a combination of a motor, a screw assembly and a slide, so that the parallel cylinder clamp 19 can be more accurately controlled to transfer back and forth between the screw 5 and the next process. The lifting cylinder 17 controls the parallel cylinder clamp 19 to move up and down to clamp the isolated and lifted screw 5. Among them, the parallel cylinder clamp 19 can be positioned by laser when clamping the screw 5, which will not be elaborated here.

[0029] Furthermore, in order to enable the parallel cylinder clamp 19 to clamp the screw 5 more stably, a clamping groove 20 suitable for clamping the screw 5 is provided between the claws of the parallel cylinder clamp 19 to correspond to the head end and the body end of the screw 5 respectively, so that the clamping and transfer are more stable.

[0030] The above description is only the preferred implementation of the utility model, and is not intended to limit the utility model. For those skilled in the art, the utility model can have various modifications and changes. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the utility model shall be included in the protection scope of the utility model.
