The embodiment is an automatic nut loading device, and the specific structure of the automatic nut loading device is shown in figures 1-7.

As shown in fig. 1, the automatic nut loading apparatus includes a material distributing mechanism 20, a robot 30, and a pushing mechanism 40. The three can be arranged on the same machine table 10. The robot 30 may employ a multi-axis robot. The material distributing mechanism 20 mainly realizes synchronous material distribution of nuts with different sizes. The separate material is then transferred by the robot 30 to the pusher mechanism 40, which in turn transfers the nuts of different sizes to an external gripper (not shown) that interfaces with the pusher mechanism 40.

As shown in fig. 2, the feed mechanism 20 includes a vibratory tray set 21, a temporary storage plate 23, a diverter plate 22, and a linear vibrator 24. The temporary storage board 23 is fixed on a supporting board 232, and the temporary storage 231 is disposed on the temporary storage board 23. The temporary storage 231 is used to store the nut transferred from the vibrating disk pack 21. The temporary storage plate 23 shown in fig. 2 is provided with 6 temporary storage locations 231, which are used for temporarily storing nuts of 6 different shapes and sizes. The vibrating disk group 21 includes two single-layer vibrating disks 211 and two double-layer vibrating disks 212. The double-layer vibrating plate 212 can fully utilize the height space and reduce the occupation of the plane space. The splitter plate 22 is provided with material flow channels 221 which are in one-to-one correspondence communication with the temporary storage locations 231. The output ends of the vibrating disk group 21 are respectively communicated with the material flow passages 221 of the splitter plate 22. Diverter plate 22 is secured to a vertical vibrator 24. The nuts sequentially flowing out of the vibrating disk set 21 pass through the material flow passage 221 of the diversion plate 22 and enter the temporary storage position 231. In addition, as shown in fig. 2, a pressing strip 222 extending along the length direction of the material flow channel 221 is disposed on a part of the material flow channel 221, so as to prevent the nut in the material flow channel 221 from being forced to displace upwards.

As shown in fig. 3, a vertical first cylinder 25 is provided below the position where the temporary storage plate 23 and the diversion plate 22 are butted. The first cylinder 25 is fixed to the side of the support plate 232. The output shaft of the first cylinder 25 faces upward. A horizontal plate 26 is fixed on the output shaft of the first cylinder 25, and 6 vertical barrier strips 261 are arranged on the horizontal plate 26. When the output shaft of the first cylinder 25 extends, the blocking strip 261 penetrates through the diversion plate 22 and is inserted into the nut of the material flow passage 221 adjacent to the temporary storage 231, that is, into the nut adjacent to the nut in the temporary storage 231, so that the nut of the material flow passage 221 is prevented from generating a pressing force on the nut in the temporary storage 231. After the manipulator removes the nut in the temporary storage position 231, the output shaft of the first cylinder 25 retracts, the material flow channel 221 transfers a nut into the temporary storage position 231, and the output shaft of the first cylinder 25 extends again to insert the barrier 261 into the nut adjacent to the nut in the temporary storage position 231.

As shown in fig. 4, the robot 30 is provided with a rotating head 31, and the rotating head 31 is provided with a plurality of second air cylinders 32.

The movable plate 42 is provided with push cylinders 422 corresponding to the material storage columns 412 one by one, and the push cylinders 422 and the movable plate 42 move synchronously. The stock column 412 extends through the pusher 422. When the movable plate 42 is gradually away from the fixed plate 41, the pushing cylinder 422 pushes the nut on the material storage column 412 outward, so that the nut is separated from the material storage column 412. When the outer gripper is engaged with the pushing mechanism 40, the nut is moved into the corresponding position by the pusher 422.

As shown in fig. 5, the pushing mechanism 40 further includes a rotating motor 43. The rotary motor 43 is fixed to a support 44. An output shaft 431 of the rotating electric machine 43 is fixedly connected to the fixed plate 41. The rotary motor 43 is used to control the fixed plate 41 to switch between the horizontal position and the vertical position. The fixed plate 41 is shown in a horizontal position in fig. 5, with the stock column 412 waiting for the robot to transfer the nut. The fixed plate 41 is shown in fig. 6 in an upright position, where the pushing mechanism 40 may be docked with the external gripper and the pushing mechanism may push the nut into a position corresponding to the external gripper.

As shown in fig. 6, the pushing mechanism 40 further includes two pushing cylinders 45. The pushing cylinders 45 are all fixed on the fixing plate 41. The output shaft of the pushing cylinder 45 is fixedly connected with the movable plate 42.

When the fixed plate 41 is in the vertical position shown in fig. 6, the output shafts of the two pushing cylinders 45 extend out synchronously to push the movable plate 42 away from the fixed plate 41, the pushing cylinder 422 moves along with the movable plate 42, and the pushing cylinder 422 pushes the nut into the corresponding position of the external paw.

As shown in fig. 7, the pushing mechanism 40 further includes a secondary cylinder 46, a secondary fixed plate 47, a secondary movable plate 48, and a tertiary cylinder 49. Two guide posts 413 are provided on the fixed plate 41 in parallel, and the guide posts 413 are perpendicular to the fixed plate 41. The guide pillar 413 penetrates the secondary movable plate 48 and the secondary fixed plate 47 in sequence. The secondary fixed plate 47 and the secondary movable plate 48 are parallel to each other. The translation directions of the secondary fixed plate 47 and the secondary movable plate 48 are both the axial directions of the guide pillar 413. The fixed plate 41 is further provided with a cantilever plate 414, and the secondary cylinder 46 is fixed to the cantilever plate 414. The secondary cylinder 46 output shaft is perpendicular to the fixed plate 41. The output shaft of the secondary cylinder 46 is fixedly connected to a secondary stationary plate 47.

The fixed plate 41 and the movable plate 42 are both provided with an avoiding hole 401 corresponding to the secondary material storage column 471 and the secondary pushing cylinder 481. The secondary stock column 471 is used to place a larger sized nut. After the pushing mechanism 40 is engaged with the external gripper and the other small sized nut has been pushed to the external gripper, the secondary cylinder 46 and the tertiary cylinder 49 are activated again to push the larger sized nut. In operation, the output shaft of the secondary cylinder 46 extends, the secondary fixed plate 47 and the secondary movable plate 48 synchronously move to the right position, then the output shaft of the tertiary cylinder 49 extends to push the secondary movable plate 48 away from the secondary fixed plate 47, the secondary push barrel 481 translates along with the secondary movable plate 48, and the secondary push barrel 481 pushes the nut with the larger size on the secondary stock column 471 into the position corresponding to the external gripper.
