DETAILED DESCRIPTION OF THE EMBODIMENTS

[0022] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0023] Refer to Figure 1 and Figure 2, an embodiment provided by the present utility model: an automatic loading and unloading device for goods in a new logistics supply chain, including a base 1. Both the left and right ends of the top of the base 1 are fixedly connected with slide rails 2. Both the front and rear ends of the two slide rails 2 are fixedly connected with fixing blocks 3. The bottom ends of the four fixing blocks 3 are fixedly connected with the top end of the base 1. Slide blocks 5 are slidably connected to the slide rails 2. The top ends of the two slide blocks 5 are fixedly connected with connecting blocks 6. Both the left and right sides of the connecting blocks 6 are fixedly connected with strengthening blocks 8. The top of the connecting block 6 is provided with a top plate 7. The bottom end of the top plate 7 is fixedly connected with the top ends of the connecting block 6 and the strengthening blocks 8. The middle of the top end of the top plate 7 is rotatably connected with a turntable 9. The bottom end of the turntable 9 is fixedly connected with a first rotating shaft 10. The bottom end of the first rotating shaft 10 is fixedly connected with a first gear 11 at the bottom end of the top plate 7. A driving assembly is arranged at the left part of the top end of the top plate 7. The driving assembly is used to drive the first gear 11 to rotate. The top end of the turntable 9 is fixedly connected with a fixed seat 12. The middle of the fixed seat 12 is rotatably connected with a robotic arm 13. The end of the robotic arm 13 is fixedly connected with a fixing member 14. The bottom end of the fixing member 14 is rotatably connected with a suction assembly. The suction assembly is used to load and unload goods of different sizes and weights.

[0024] When the slide block 5 slides on the slide rail 2, it will drive the top plate 7 to move synchronously, changing the positions of the robotic arm 13 and the suction assembly. By driving the driving assembly to drive the first gear 11 to rotate, the first rotating shaft 10, the turntable 9 and the fixed seat 12 are driven to rotate synchronously, changing the direction of the robotic arm 13. Different sizes and weights of goods can be sucked through the suction assembly, and the possibility of the goods falling off is reduced.

[0025] Refer to Figure 1 and Figure 2 , the driving assembly includes a first motor 15. The first motor 15 is fixedly connected with the top of the top plate 7. The output end of the first motor 15 is fixedly connected with a second rotating shaft 16. The bottom end of the second rotating shaft 16 is fixedly connected with a second gear 17. The second gear 17 is located at the bottom end of the top plate 7. The outer end of the second gear 17 is meshed with the outer end of the first gear 11.

[0026] Start the first motor 15 to drive the second rotating shaft 16 and the second gear 17 to rotate. Since the second gear 17 is meshed with the first gear 11, the rotation of the second gear 17 will drive the first gear 11 to rotate in the opposite direction.

[0027] Refer to Figure 1 and Figure 3, the suction component includes a fixing plate 18. Both the left and right ends of the top of the fixing plate 18 are fixedly connected with connecting columns 19. The two connecting columns 19 are respectively rotatably connected to the bottoms of the left and right ends of the fixing member 14. T-shaped grooves 20 are opened on both the left and right sides of the bottom end of the fixing plate 18. A second motor 21 is fixedly connected to the right end of the fixing plate 18. The output end of the second motor 21 is fixedly connected with a bidirectional lead screw 22. T-shaped blocks 23 are threadedly connected inside the T-shaped grooves 20 of the bidirectional lead screw 22. The bottoms of the two T-shaped blocks 23 and the middle of the bottom end of the fixing plate 18 are all fixedly connected with electric telescopic rods 24. The output ends of the left and right electric telescopic rods 24 are fixedly connected with a first suction cup 25. The output end of the middle electric telescopic rod 24 is fixedly connected with a second suction cup 26. A vacuum pump 27 is arranged at the top end of the fixing plate 18. Both output ends of the vacuum pump 27 are fixedly connected with main pipes 28. Three branch pipes 29 are fixedly connected to the ends of the two main pipes 28. The ends of the branch pipes 29 are respectively communicated with the inside of the first suction cup 25 and the electric telescopic rod 24. The T-shaped block 23 is slidably connected with the T-shaped groove 20 on the same side. The bottom of the outer end of the vacuum pump 27 is fixedly connected with a support 30. The bottom end of the support 30 is fixedly connected with the top end of the fixing plate 18. A conveying device 4 is fixedly connected to the top end of the base 1. The width of the fixing plate 18 is less than or equal to the width of the conveying device 4. The slide rails 2 are respectively located at the left and right ends of the conveying device 4.

[0028] Since the connecting column 19 and the fixing member 14 are rotatably connected, the fixing plate 18 is always horizontal. Start the second motor 21 to drive the bidirectional lead screw 22 to rotate, so that the T-shaped block 23 moves in the reverse direction inside the T-shaped groove 20 on the same side, thereby driving the left and right electric telescopic rods 24 and the first suction cup 25 to move with the T-shaped block 23 on the same side. Starting the electric telescopic rod 24 can drive the first suction cup 25 and the second suction cup 26 to move up and down synchronously. When the first suction cup 25 and the second suction cup 26 are in contact with the top of the goods, the vacuum pump 27 can be started to pump out the air between the first suction cup 25, the second suction cup 26 and the goods, forming a vacuum environment to facilitate the adsorption of the goods. The first suction cup 25 and the second suction cup 26 cooperate with each other to adsorb goods of different sizes and weights.

[0029] Working principle: The goods are conveyed through the conveying device 4. By starting the second motor 21, the two first suction cups 25 can be moved in the reverse direction, so that the first suction cups 25 move to both ends of the top of the goods. Then start the electric telescopic rod 24 to make the first suction cup 25 and the second suction cup 26 move down synchronously to fit the goods. Then, the vacuum pump 27 is used to evacuate the first suction cup 25 and the second suction cup 26 to facilitate lifting large goods. The first suction cups 25 are on both sides of the goods, making the force on the goods uniform and preventing them from falling off. When the goods are small, only the second suction cup 26 can be used. By starting the first motor 15, the first gear 11, the first rotating shaft 10 and the turntable 9 can be driven to rotate, thereby driving the robotic arm 13 to rotate, changing the direction of the sucked goods, and facilitating the handling of the goods to different directions and heights.

[0030] Finally, it should be noted that the above are only the preferred embodiments of the present utility model and are not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions recorded in the foregoing embodiments or perform equivalent replacements for some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present utility model shall be included within the protection scope of the present utility model.
