[0042] like Figure 2 and Figure 5 As shown, the continuous feeding device 100 for round nut stop washers includes a direct vibration feeding mechanism 1, a material dividing mechanism 2 and a material receiving mechanism 3. The direct vibration feeding mechanism 1 is arranged on a base 4, and the base 4 is provided with a material unloading assembly port 41 corresponding to the rotor 400 on the accompanying tooling plate 200; corresponding to the material unloading assembly port 41, a round nut stop washer transfer mechanism 5 is provided on the base 4.

[0043] like Figure 3 As shown, the direct vibration feeding mechanism 1 includes a low-frequency conveyor 11 and a limiting carrier 12 fixed on the low-frequency conveyor 11, and the limiting carrier 12 stacks the round nut stop washers to be taken; the limiting carrier 12 is provided with a first limiting groove 121 to position the inner stop ear of the round nut stop washer.

[0044] like Figure 4 As shown, the material dividing mechanism 2 is provided with a telescopic material dividing component 21. When discharging materials, the telescopic material dividing component 21 is extended and inserted between the current round nut stop washer to be taken and the next round nut stop washer to be taken; two telescopic material dividing components 21 are arranged along the straight vibration conveying direction and are driven by a cylinder.

[0045] like Figure 2 and Figure 5As shown, the material receiving mechanism 3 is arranged at the discharge end of the direct vibration feeding mechanism 1, and is fixed on the linear displacement moving part of the second linear displacement mechanism 31 of the Y-axis. The material receiving mechanism 3 receives the round nut stop washer to be taken from the direct vibration feeding mechanism 1 from the material receiving station and translates it to the transfer station of the transfer mechanism 5; in this embodiment, the round nut stop washer is made of magnetic conductive material; correspondingly, the material receiving mechanism adopts a magnetic material suction mechanism. The magnetic material suction mechanism includes a material receiving tray 32 and a plurality of micro magnets arranged on the back of the material receiving tray 32. The micro magnets absorb the round nut stop washer and are fixed on the material receiving tray 32. The material receiving tray 32 is provided with a second limiting groove to limit the inner stop ear of the round nut stop washer.

[0046] The transfer mechanism 5 includes an X-axis first linear displacement mechanism 51, a Z-axis first linear displacement mechanism 52, a first rotation mechanism 53 and a clamping mechanism 54, wherein the Z-axis first linear displacement mechanism 52 is arranged on the linear displacement motion component of the X-axis first linear displacement mechanism 51, the first rotation mechanism 53 is arranged on the linear displacement motion component of the Z-axis first linear displacement mechanism 52, the first rotation mechanism 53 is provided with an L-shaped adapter plate 55, the L-shaped adapter plate 55 is provided with a second rotation mechanism 56, and the clamping mechanism 54 is fixed on the second rotation mechanism 56; the clamping mechanism 54 includes a clamping claw 541 and a clamping claw cylinder 542, and the clamping claw cylinder drives the clamping claw to open and close to collect the round nut stop washer to be taken;

[0049] When the embodiment is working, the low-frequency conveyor 11 conveys the round nut stop washers 300 to the material receiving station; the material separation mechanism 2 screens and blocks, so that the round nut stop washers 300 are separated in order;

[0050] The separated round nut stop washer 300 is automatically transferred to the receiving tray 32 through the micro magnet and is limited by the second limiting groove 33 on the receiving tray to ensure the accurate direction when transferring the round nut stop washer;
