[0016] The present invention will be described in more detail below with reference to the accompanying drawings and embodiments.

[0017] The utility model discloses a special-shaped nut flip feeding device, combined with Figures 1 to 3As shown, it includes an upper platform 1 and a lower platform 2, at least one feeding mechanism 3 is provided on the top of the upper platform 1, a discharge switch mechanism 4 connected to the discharge end of the feeding mechanism 3 is provided on the edge of the upper platform 1, a forward and backward moving slide 5 and a slide driving mechanism 6 for driving the forward and backward moving slide 5 to translate forward and backward are provided on the top of the lower platform 2, a hand-gripping positioning platform 7 is provided in the middle of the forward and backward moving slide 5, a vertical bracket 8 is provided at the edge of the forward and backward moving slide 5, a flip arm 9 which can be flipped within an angle range of 90° is provided on the top of the vertical bracket 8, a plurality of feeding rods 10 which can be inserted into the lower end opening of the discharge switch mechanism 4 and a feeding cylinder 11 for driving the feeding rod 10 to move up and down are provided on the flip arm 9.

[0018] In the above structure, the feeding mechanism 3 can continuously convey the special-shaped nuts to the discharging switch mechanism 4 by means of vibration feeding or the like. When picking up materials, the slide drive mechanism 6 drives the forward and backward moving slide 5 to move downwardly toward the discharging switch mechanism 4 until the vertical picking rod 10 is aligned with the lower opening of the discharging switch mechanism 4, and the picking cylinder 11 drives the picking rod 10 to insert into the lower opening of the discharging switch mechanism 4, and then the discharging switch mechanism 4 performs a switching action to fit a special-shaped nut onto the picking rod 10. The slide drive mechanism 6 drives the forward and backward motion slide 5 to move step by step until all the multiple material picking rods 10 on the flip arm 9 are covered with special-shaped nuts. Then, the slide drive mechanism 6 drives the forward and backward motion slide 5 to move to the side away from the feeding mechanism 3. After the robot gripper is placed on the gripper positioning platform 7 and positioned with each other, the flip arm 9 is flipped 90° from the vertical state, and the material picking rod 10 is horizontally aligned with the material discharge rod on the robot gripper. The material picking cylinder 11 drives the material picking rod 10 to telescopically move, completing the loading process of the robot gripper. Compared with the prior art, the utility model can automatically supply special-shaped nuts and automatically install nuts on the robot gripper. The whole process not only saves time and effort, but also greatly improves work efficiency.

[0019] To achieve batch feeding, in this embodiment, see Figure 1 , two feeding mechanisms 3 are arranged on the top of the upper machine table 1, and vertical brackets 8 are arranged at the edges of both sides of the front and rear moving slide 5, respectively. Each vertical bracket 8 is provided with a flip arm 9, and the flip arm 9 corresponds to the feeding mechanism 3 one by one. Based on the above structure, this embodiment can simultaneously supply special-shaped nuts to the pick-up rods 10 on the left and right sides, and then the pick-up rods 10 on the left and right sides simultaneously grab the special-shaped nuts to the robot hand, which can significantly improve the working efficiency of picking and installing nuts.

[0020] In order to position the robot gripper reliably and ensure that the special-shaped nut is reliably installed in place, in this embodiment, please refer to Figure 3, two hand-grasping positioning blocks 70 are arranged on the hand-grasping positioning platform 7. Further, the two hand-grasping positioning blocks 70 are arranged at the front and rear ends of the hand-grasping positioning platform 7.

[0021] As a preferred embodiment, the feeding mechanism 3 is a vibrating plate feeding mechanism. However, this is only a preferred application of the present invention. In actual applications, the feeding mechanism 3 can be replaced by other types of feeding mechanisms.

[0022] See also Figure 2 In this embodiment, two vertical material guide mechanisms 30 are provided at the edge of the upper machine table 1, and the material discharging switch mechanism 4 is provided at the lower end of the vertical material guide mechanism 30, and the upper end of the vertical material guide mechanism 30 is connected to the material discharging end of the feeding mechanism 3 through the material pipe 31. The special-shaped nuts conveyed by the feeding mechanism 3 in a vibration manner slide into the vertical material guide mechanism 30 through the material pipe 31, and then the special-shaped nuts are mounted on the material taking rod 10 one by one by controlling the material discharging switch mechanism 4 to gradually perform the opening and closing state.

[0023] Furthermore, the material discharging switch mechanism 4 includes a material guiding cylinder 40 fixed to the side of the vertical material guiding mechanism 30, and the moving end of the material guiding cylinder 40 is provided with two switch control claws 41, and the two switch control claws 41 are both extended into the material guiding channel of the vertical material guiding mechanism 30. In this embodiment, the material guiding cylinder 40 is preferably used to control the synchronous opening and closing movement of the two switch control claws 41, see Figure 2 When the two switch control claws 41 are opened, the channel of the vertical material guiding mechanism 30 can be opened, so that a special-shaped nut is mounted on the material picking rod 10. When the material guiding cylinder 40 controls the two switch control claws 41 to clamp, the vertical material guiding mechanism 30 can be closed. At this time, no special-shaped nut is sent out, thereby realizing automatic feeding control.

[0024] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions or improvements made within the technical scope of the present invention should be included in the scope of protection of the present invention.
