[0029] To make the objectives and advantages of this utility model clearer, the following detailed description is provided in conjunction with embodiments. It should be understood that the following text is merely used to describe one type of goods sorting robot or several specific implementations of this utility model, and does not strictly limit the scope of protection specifically claimed by this utility model. As used herein, the terms up / down and left / right are not limited to their strict geometric definitions, but rather include tolerances for reasonable and inconsistent machining or human errors. The specific features of this goods sorting robot are described in detail below:

[0030] Reference Figures 1-11According to an embodiment of the present invention, a cargo sorting robot includes a body 1, several rollers 2 are installed at the bottom of the body 1, at least one connecting rod 4 is rotatably installed at the top of the body 1, and a tray 3 is installed on the connecting rod 4. The edge of the tray 3 is provided with an upwardly angled barrier to prevent cargo from falling. This is a conventional structure of a cargo sorting robot.

[0031] Current cargo sorting robots lack a structure to secure the cargo. During transportation, the cargo may shake or even tip over when encountering sudden stops or other situations. To solve this problem, the inventors considered making the following improvements.

[0032] A connecting block 10 is installed inside the pallet 3. A groove 5 is formed on the connecting block 10. A threaded rod 7 is rotatably installed inside the groove 5. A motor 13 is installed at one end of the groove 5 and is connected to the threaded rod 7. The threaded rod 7 has a double-ended reverse thread. A slider 6 and a slider 11 are slidably installed inside the groove 5. An internal thread 8 is formed inside the slider 6, and an internal thread 12 is formed inside the slider 11. The threaded rod 7 is threadedly connected to the slider 6 and the slider 11. A clamping plate 9 is fixedly installed on the slider 6 and the slider 11. After the goods are placed inside the pallet 3, the motor 13 is started to drive the threaded rod 7 to rotate, controlling the slider 6 and the slider 11 to move synchronously towards the center, causing the clamping plate 9 to move inward to clamp the goods. Finally, the robot is controlled to transport the goods according to the corresponding route, which can effectively avoid the risk of the goods falling during transportation and improve the picking efficiency.

[0033] Furthermore, inclined plates 19 are fixedly installed inward on the clamping plate 9, and infrared sensors 15 are installed on the top of the inner sides of the two inclined plates 19. After the goods are placed on the pallet 3, the clamping plate 9 is controlled to clamp inward. The inclined plates 19 can prevent bagged goods from falling off. When the infrared sensor 15 detects the goods, the motor 13 is controlled to stop running to complete the fixation of the goods. This can effectively avoid excessive movement of the clamping plate 9 and damage to the shape of the goods.

[0034] Furthermore, two sliding grooves 21 are formed on both sides of the connecting block 10, and a slider 22 is slidably installed in the sliding grooves 21. A clamping plate 20 is fixedly installed inwardly on the slider 22. Two sliding grooves 24 are formed on the connecting block 10, and sliders 29 are respectively installed at the bottom of both ends of the clamping plate 29. The sliders 29 are slidably connected to the sliding grooves 24. A groove 23 is formed on the inner side of the sliding grooves 24. A connecting rod 30 is rotatably installed at different heights of the sliders 29 on both sides. A connecting rod 31 is installed on the slider 22. The connecting rod 30 and the... The other end of the connecting rod 31 is connected and placed in the groove 23. A through hole 32 is opened on the inner side of the groove 21, and the connecting rod 31 is slidably connected to the through hole 32. When the slider 6 and the slider 11 are controlled to slide inward, the two connecting rods 30 are driven to rotate inward. The connection between the connecting rod 30 and the connecting rod 31 moves inward and drives the connecting rod 31 to move inward. The connecting rod 31 drives the slider 22 to slide inward, so that the clamping plate 20 clamps the goods, realizing all-round protection of the goods and improving the stability of goods transportation.

[0035] Furthermore, in order for the robot to drop the goods into the designated position after reaching the designated position, the above structure requires first controlling the clamp 9 to slide outward, and then controlling the tray 3 to flip so that the goods fall into the designated position. In order to improve the picking efficiency, the inventors considered making the following improvements.

[0036] Hinges 16 are fixedly installed on slider 1 (6) and slider 2 (11) respectively. Rotating shafts 18 are fixedly installed on both sides of the hinges 16. A rotating groove 17 is opened at the bottom of clamping plate 1 (9). The hinges 16 are installed in the rotating groove 17. The clamping plate 1 (9) is rotatably connected to the rotating shaft 18. A motor 2 (14) is installed on the rotating shaft 18. After reaching the designated position, the motor 2 (14) is controlled to rotate, causing the clamping plate 1 (9) to rotate outward. Then, the pallet 3 is controlled to rotate, causing the goods to fall to the corresponding position. After completion, the motor 2 (14) is controlled to rotate, causing the clamping plate 1 (9) to return to its original position, making the clamping plate 1 (9) perpendicular to the connecting block 10. This method is faster and more convenient than controlling slider 1 (6) and slider 2 (11) to slide outward, thus improving the efficiency of goods sorting.

[0037] Furthermore, to ensure that the rotation of the clamping plate 9 is not affected by the slider 29, rotation grooves 25 are respectively opened at the bottom of both ends of the clamping plate 9. Connecting members 28 are slidably installed in the rotation grooves 25, and fixing rods 27 are fixedly installed on both sides of the connecting members 28. Rotation grooves 36 are opened on both sides of the rotation grooves 25, and the fixing rods 27 are slidably connected to the rotation grooves 36. The slider 29 is fixedly installed at the bottom of the connecting members 28. The clamping plate 9 is controlled to rotate outward by the motor 14, the connecting members 28 slide in the rotation grooves 25, and the fixing rods 27 slide in the rotation grooves 36, ensuring that the clamping plate 9 can rotate normally.

[0038] The specific implementation process is as follows:

[0039] The goods are placed in the tray 3. The motor 13 drives the two clamping plates 9 to move inward to clamp the goods. When the clamping plates 9 move, the connecting rods 30 on both sides move towards the center, which in turn drives the connecting rod 31 to move towards the center, causing the slider 22 to move towards the center and the clamping plate 20 to clamp the goods. After the infrared sensor 15 detects the goods, the motor 13 stops running, stopping the clamping plates 9 and 20. After reaching the designated position, the motor 14 drives the clamping plates 9 to rotate outward, and then the tray 3 is flipped so that the goods fall into the designated position.

All such modifications fall within the protection scope of this utility model. The protection scheme of this utility model is defined by the appended claims.
