[0019] See also Figure 1-3 , the utility model provides a technical solution:

[0020] A 3D printing picking device, comprising a four-wheel platform 1 and a lifting picking hand, a mounting plate 2 is arranged on one side of the top of the four-wheel platform 1, a lifting column 3 is arranged at the top center of the mounting plate 2, the top of the lifting column 3 is connected to the bottom center of the mounting rod 4, placement blocks 5 are arranged at both ends of the front of the mounting rod 4, a monitoring camera 6 is fixedly connected to the top of the placement block 5, a rotating seat 7 is arranged at the center of the other side of the top of the four-wheel platform 1, an inner cavity is opened at the top of the rotating seat 7, a driving motor 18 is arranged at the bottom center of the inner cavity, the top output end of the driving motor 18 is connected to the rotating shaft, a through hole 20 is opened at the top center of the rotating seat 7, a rotating shaft is arranged inside the through hole 20, the top of the rotating shaft is located at the top of the rotating seat 7, and the top of the rotating shaft is connected to the rotating plate 8 is connected to the bottom center of the rotating plate 8, and a liftable picking hand is arranged on the top of the rotating plate 8, and the liftable picking hand includes a stand 9, a lifting cylinder 11, a lifting rod 12, and a lifting plate 13. The bottom of the stand 9 is fixedly connected to the top of the rotating plate 8, and a stand inner cavity 10 is opened inside the stand 9. A lifting rod 12 is arranged on the top of the stand inner cavity 10, and the lifting rod 12 is connected to the stand 9 through a damping shaft. Second fixed blocks 16 are arranged on both sides of the other end of the lifting rod 12, and a rotating block 17 is arranged between the two second fixed blocks 16. The rotating block 17 is connected to the two second fixed blocks 16 through a damping shaft. The top of the rotating block 17 is connected to the bottom center of the lifting plate 13, and a flexible picking hand 14 is arranged at the top center of the lifting plate 13.

[0021] Specifically, the flexible picking hand 14 is obtained by 3D printing. The flexible picking hand 14 includes a wrist, fingers, a grasping airbag, a swallowing airbag, and a base. The flexible picking hand 14 is driven pneumatically. The grasping airbag is used for driving during the bending of the wrist, and the swallowing airbag is used for driving during the grasping and swallowing of the fruit. The two airbags are driven in a coordinated manner to drive the flexible fingers to apply clamping force to the picking object. During the grasping and clamping process, the flexible fingers automatically bend and deform according to the shape of the fruit to achieve adaptive grasping and clamping in the picking process. When grasping begins, there is negative pressure gas in the grasping airbag and the swallowing airbag, the airbag is in a compressed state, and the flexible fingers are fully opened. When in contact with the picking object, the swallowing airbag continues to remain in a compressed state, and the grasping airbag is filled with positive pressure gas, which drives the lower part of the wrist to begin to bend, and drives the lower part of the flexible fingers to begin to gather, so as to clamp the picking object. The flexible fingers adaptively change their appearance shape to maintain a close fit with the picking object to complete the grasping.

[0022] It should also be noted that the base and wrist are made of titanium-magnesium alloy, which can meet the strength requirements during use, while reducing the weight of the structural design and the processing allowance during the manufacturing process. The flexible fingers are printed with aluminum alloy to ensure the elasticity and flexibility of the fingers during the picking process.

[0023] Finally, it should be noted that after printing is completed, the flexible picking hand 14 is fixedly connected to the lifting plate 13 .

[0024] Furthermore, a rotating slot 21 is provided on the top of the rotating seat 7 , and a snap ring 19 is snap-fittedly connected to the rotating slot 21 , and the top of the snap ring 19 is connected to the rotating plate 8 .

[0025] Furthermore, a lifting cylinder 11 is provided at the bottom of the seat inner cavity 10 , and the lifting cylinder 11 is connected to the seat 9 via a damping shaft, and the other end of the lifting cylinder 11 is located at the bottom of the lifting rod 12 .

[0026] Furthermore, first fixing blocks 15 are provided at both ends of the middle of the bottom of the lifting rod 12, and the other end of the lifting cylinder 11 is located between the two first fixing blocks 15, and the lifting cylinder 11 and the first fixing blocks 15 are connected via a damping shaft.

[0027] Working principle: When in use,

[0028] S1: The staff can control the four-wheel platform 1 to move forward, backward and turn, thereby making the new type of vehicle move.

[0029] S2: After moving to a suitable place, the staff can control the driving motor 18 to rotate through the controller. The rotation of the driving motor 18 will rotate the rotating shaft, and the rotation of the rotating shaft will rotate the rotating plate 8. The rotation of the rotating plate 8 will rotate the liftable picking hand, thereby rotating the liftable picking hand to a certain place.

[0030] S3: After rotating to a certain position, the staff can control the lifting cylinder 11 to extend through the controller. The extension of the lifting cylinder 11 will change the angle between the lifting rod 12 and the stand 9, and then lift the lifting plate 13, thereby moving the flexible picking hand 14 to a certain height for picking.

[0031] S4: During the picking process, the lifting plate 13 may touch objects around the picked objects, and then the lifting plate 13 will be acted upon by a force, so that the angle between the lifting plate 13 and the lifting rod 12 changes to a certain extent, so that the picked objects can be picked better.

[0032] Finally, it should be noted that the utility model can achieve remote control through two monitoring cameras 6, wherein how to achieve communication between the monitoring cameras 6 and the remote controller is a prior art, and its specific structure and working principle will not be described in detail here.

[0033] Although the embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
