[0023] The utility model is further described below in conjunction with the accompanying drawings and implementation modes.

[0024] Reference Figure 1-4 , please refer to Figure 1-Figure 4 ,in, Figure 1 A three-dimensional structure diagram of a precise automatic feeding mechanism for plastic parts proposed in the utility model Figure 1 ; Figure 2 A three-dimensional structure diagram of a precise automatic feeding mechanism for plastic parts proposed in the utility model Figure 2 ; Figure 3 A three-dimensional structure diagram of a precise automatic feeding mechanism for plastic parts proposed in the utility model Figure 3 ; Figure 4 The figure is a schematic diagram of the disassembly of the three-dimensional structure inside the connecting rod. A precise automatic feeding mechanism for plastic parts comprises: a plastic parts feeding platform 1, a rotating shaft 2 is rotatably mounted on the plastic parts feeding platform 1, a support 6 is fixedly mounted on the rotating shaft 2, a plastic parts guide groove 7 is arranged on the upper side of the support 6, a notch 8 is provided on the outer side of the support 6, a feeding bin 9 is rotatably mounted inside the notch 8, a toothed disc 3 and a mounting ring 12 are fixedly mounted on the outer side of the rotating shaft 2, an electric telescopic rod 11 is installed between the mounting ring 12 and the bottom of the feeding bin 9, a servo motor 4 is fixedly mounted on the upper side of the plastic parts feeding platform 1, a gear 5 is fixedly mounted on the output end of the servo motor 4, a shaft seat 10 is fixedly mounted on the bottom of the feeding bin 9, the shaft seat 10 is rotatably connected to the output end of the electric telescopic rod 11, a shaft groove 13 is provided on the side of the mounting ring 12, the shaft groove 13 is rotatably connected to the bottom of the electric telescopic rod 11, and an automatic feeding component is arranged on the side of the rotating shaft 2.

[0025] By setting up in the above manner, starting the servo motor 4 can drive the gear 5 to rotate, and then the gear 5 drives the rotating shaft 2 to rotate through the meshing action with the toothed disc 3, and further provides a rotational driving action on the support platform 6 on the upper side of the rotating shaft 2, so that the support platform 6 drives the feed bin 9 set thereon to rotate, thereby realizing the continuous rotation feeding function.

[0026] In this method, the automatic feeding assembly includes a connecting rod 14 and a conductive contact 16. A cylindrical groove 19 is opened at the end of the connecting rod 14. A spherical contact head 20 is slidably installed inside the cylindrical groove 19. A spring 21 is fixedly connected between the spherical contact head 20 and the bottom of the cylindrical groove 19. The conductive contact 16 is fixedly installed on the side of the rotating shaft 2.

[0027] Through the arrangement in the above manner, when the conductive contact 16 rotates to the spherical contact head 20, the spring 21 arranged on the inner side of the spherical contact head 20 retracts under the contact force, and at the same time, the spherical contact head 20 maintains sufficient contact with the conductive contact 16 in the contact area under the action of the rebound force of the spring 21, so that the circuit is stably turned on. When the conductive contact 16 passes through the spherical contact head 20, the spherical contact head 20 rebounds and resets under the action of the rebound force of the spring 21, waiting for contact with the next conductive contact 16.

[0028] In this embodiment, the toothed disc 3 is meshed with the gear 5 , and the diameter of the toothed disc 3 is greater than the diameter of the gear 5 .

[0029] In this embodiment, several groups of notches 8 and feed bins 9 are equidistantly arranged along the circumference of the support platform 6 , and several groups of conductive contacts 16 are equidistantly arranged along the outer circumference of the rotating shaft 2 , and the distribution positions of the conductive contacts 16 correspond one-to-one to the feed bins 9 .

[0030] Through the above-mentioned arrangement, the distribution positions of the conductive contacts 16 correspond one-to-one with the feed bin 9, so that the conductive contacts 16 maintain a one-to-one control relationship with the electric telescopic rod 11 at the bottom of the feed bin 9. When the feed bin 9 rotates to the feeding point, the conductive contacts 16 turn on the electric telescopic rod 11, so that the electric telescopic rod 11 completes a contraction and reset operation, thereby realizing the automatic flipping and resetting of the feed bin 9, and further realizing the automatic feeding function.

[0031] In this embodiment, the conductive contact 16 is provided with an arc-shaped guide edge 17, and both the conductive contact 16 and the spherical contact head 20 are connected to the power supply circuit.

[0032] By the above arrangement, the arc-shaped guide edge 17 of the conductive contact 16 is arranged so that when the conductive contact 16 contacts the spherical contact head 20, contact scratches are reduced under the contact guidance of the arc surface.

[0033] In this embodiment, a mounting base 18 is fixedly connected to the bottom of the connecting rod 14, and the mounting base 18 is screwed and installed on the plastic parts feeding platform 1. A shell 15 is fixedly installed on the side of the connecting rod 14. The shell 15 is sleeved on the outside of the spherical contact head 20 and the conductive contact 16, and the inner side of the shell 15 is in rotational contact with the side wall of the rotating shaft 2.

[0034] Through the above-mentioned arrangement, the arrangement of the housing 15 protects the conductive contact 16 and the spherical contact head 20, prevents the conductive contact pole from leaking out, and improves the safety of use.

[0035] The working principle of a precise automatic feeding mechanism for plastic parts provided by the utility model is as follows:

[0036] When in use, start the servo motor 4, and the output end of the servo motor 4 drives the gear 5 to rotate. The gear 5 drives the rotating shaft 2 to rotate through the meshing action with the toothed disc 3, and the rotating shaft 2 further drives the supporting platform 6 at its upper end to rotate, and the plastic parts are input into the feeding bin 9 through the plastic parts guide groove 7. The feeding bin 9 drives the plastic parts to follow the supporting platform 6 to rotate and feed. When the feeding bin 9 rotates to the loading point, the conductive contact 16 corresponding to the lower side of the feeding bin 9 contacts the spherical contact head 20, thereby realizing the power supply function of the electric telescopic rod 11 arranged on the lower side of the feeding bin 9, so that the electric telescopic rod 11 completes a contraction and reset work, realizes the automatic flipping and resetting function of the feeding bin 9, and dumps the plastic parts in the feeding bin 9 to the feeding point, thereby realizing the automatic feeding function.

[0037] Compared with the related art, the precise automatic feeding mechanism for plastic parts provided by the utility model has the following beneficial effects:

[0038] The utility model provides a precise automatic feeding mechanism for plastic parts. The utility model arranges a plurality of groups of feeding bins 9 equidistantly on the circumference of a base 6, and adopts a rotating continuous feeding method, thereby maintaining continuity during the feeding process. Compared with the traditional intermittent feeding method, the feeding efficiency is greatly improved. In addition, the matching automatic feeding component realizes a fully automatic feeding function, thereby improving practicality.
