In this embodiment, the automatic lifting platform 15 is a hydraulic scissor lifting platform in the prior art.

[0034] The movable end of the translation and rotation mechanical arm is fixedly provided with a grab disc mechanism for grabbing the outer protective box 2. The translation and rotation mechanical arm is used to drive the grab disc mechanism to move up and down and rotate and translate in the horizontal plane, and the translation and rotation mechanical arm can translate the outer protective box 2 to the directly above of the automatic lifting platform 15.

[0035] The automatic lifting platform 15 is used to push the left-opened middle protective box 16 on the automatic lifting platform 15 into the outer protective box 2, and the anti-falling mechanism 7 is used to prevent the middle protective box 16 from falling out of the outer protective box 2.

[0036] Specifically, as shown in Figure 1 The translation and rotation mechanical arm includes a support rod 8 vertically arranged on the ground, and a rotation driving device 9 is fixedly arranged at the top of the support rod 8. In this embodiment, the rotation driving device 9 is a servo motor.

The lifting arm 11 is used to raise or lower the height of the grab disc mechanism.

[0037] As shown in Figure 4 The grab disc mechanism includes a fixed disc 12, a plurality of first telescopic devices 13 are vertically fixedly arranged on the circumferential side of the fixed disc 12, the end of the first telescopic device 13 away from the fixed disc 12 is fixedly connected with a hooking plate 14, the hooking plate 14 is a vertically arranged L-shaped plate structure, and the lower bent part of the hooking plate 14 is used to hook the bottom of the convex ring 4.

[0038] A plurality of boxes 18 are arranged on the second conveying device 17, and a box pushing mechanism is arranged on the left side of the second conveying device 17. The box pushing mechanism is used to push the boxes 18 on the second conveying device 17 into the middle protective box 16. Specifically, as shown in Figure 1As shown, the goods pushing mechanism includes a fixed frame 19 fixedly arranged on the ground, a second telescopic device 20 fixedly arranged on the right side of the fixed frame 19, and a pushing plate 21 fixedly arranged on the right end of the second telescopic device 20.

[0039] In this embodiment, the motion time control of the translational rotary mechanical arm and the goods pushing mechanism can be automatically controlled by the light emitting device and the light receiving device of the photoelectric sensor arranged on the left and right sides of the first conveying device 1 and the second conveying device 17, and the controller (such as a single-chip microcomputer or a PLC controller). This technology is prior art, and the specific connection and structure thereof will not be described in detail.

[0040] In this embodiment, the first telescopic device 13, the second telescopic device 20 and the lifting arm 11 are all gas cylinders, which can be replaced by hydraulic cylinders or electric push rods in other embodiments.

[0041] In this embodiment, the middle protective box 16 and the outer protective box 2 are both made of hard plastic or metal to improve the anti-collision and rainproof effects.

[0042] Working principle: when in use, the outer protective boxes 12 carried by the unmanned aerial vehicle are placed on the first conveying device 1 at intervals, so that the first conveying device 1 drives the unmanned aerial vehicle and the outer protective boxes 12 to move backward, at the same time, the goods boxes 18 packed with goods are placed on the second conveying device 17 at intervals, and the middle protective boxes 16 are placed on the automatic lifting platform 15.

[0043] When the goods box 18 moves to the left side of the automatic lifting platform 15, the second conveying device 17 is paused, the second telescopic device 20 of the goods pushing mechanism is extended, and the goods box 18 is pushed into the left opening middle protective box 16 through the pushing plate 21. The goods pushing mechanism is retracted, and the second conveying device 17 continues to move.

[0044] Then, after the outer protective box 2 is conveyed to the position by the first conveying device 1, the first conveying device 1 is paused, the translational rotary mechanical arm grasps the outer protective box 2 in position through the grabbing disc mechanism, and moves the outer protective box 2 to the position directly above the automatic lifting platform 15. The automatic lifting platform 15 is controlled to rise, and the middle protective box 16 is pushed into the outer protective box 2. In the process of pushing the middle protective box 16 into the outer protective box 2, the movable rod 702 is automatically pushed outwards. After the bottom of the middle protective box 16 moves to the position above the movable rod 702, the movable rod 702 is automatically popped out to the bottom of the middle protective box 16 under the pushing of the spring 705, so as to support the middle protective box 16 and prevent the middle protective box 16 from falling out of the outer protective box 2.

[0045] During transportation, since the middle protective box 16 adopts a left opening mode, the bottom of the goods box 18 will not be deformed by the extrusion of the movable rod 702, and the protection effect on the goods is better.

[0046] After being delivered to the site, the operator pulls the outer end of the movable rod 702, and the middle protective box 16 and the goods box 18 are automatically dropped from the outer protective box 2 under the action of gravity.

[0047] After the goods box 18 is taken out from the middle protective box 16, the middle protective box 16 is reloaded into the outer protective box 2, and the unmanned aerial vehicle returns automatically with the empty middle protective box 16 and the outer protective box 2.

[0048] Embodiment 2: unmanned aerial vehicle goods box loading line, the difference between this embodiment and embodiment 1 is that the middle protective box 16 is no longer arranged. In use, the goods pushing mechanism is used to push the goods box 18 on the second conveying device 17 to the automatic lifting platform 15, and the automatic lifting platform 15 is used to push the goods box 18 on it into the outer protective box 2. The other use mode is the same as that of embodiment 1.

[0049] It is obvious for those skilled in the art that the present application is not limited to the details of the above exemplary embodiments, and can be realized in other specific forms without departing from the spirit or essential characteristics of the present application. Therefore, from any point of view, the embodiments should be regarded as exemplary and non-limiting, the scope of the present application is defined by the appended claims rather than the above description, and therefore all changes falling within the meaning and scope of the equivalent elements of the claims are intended to be included in the present application.
