Description

Technical Field

[0001] This application proposes a flip-plate mechanism for three-dimensional sorting and a sorting robot using the mechanism, belonging to the field of logistics warehousing and automation control. Background Technology

[0002] Currently, in the logistics and warehousing field, sorting robots, also known as self-navigating sorting carts, have been widely used for cargo transportation and unloading. In practical applications, goods are typically unloaded at a predetermined exit as needed. For example, packages are unloaded at different exits based on geographical location, and then packages at the same exit are packaged and transported together.

[0003] Existing sorting robots typically use flip-plate mechanisms driven by electric push rods or hydraulic combined mechanical mechanisms, which are relatively complex in structure. In addition, increasing the load capacity of the flip-plate requires a large amount of equipment space, which is a significant limitation for small equipment with limited space. Moreover, the existing flip-plate mechanisms have a small flip angle range, which directly affects the sorting efficiency.

[0004] In view of the above, this patent application is hereby filed. Utility Model Content

[0005] The flipping mechanism and sorting robot using the mechanism described in this application aim to solve the problems existing in the prior art by proposing a gear and rack-and-pinion gearbox drive structure to achieve the flipping of heavy materials in a confined space, thereby increasing the flipping load and the flipping angle.

[0006] To achieve the above design objectives, the flipping mechanism includes a flipping base connected to the main body of the sorting robot. A gearbox drive assembly is installed on the flipping base. The gearbox drive assembly drives the flipping body to flip vertically via the flipping bracket to achieve goods sorting. A set of concave slide rails are respectively provided on both sides of the top of the flipping base. A set of drive shafts is pivotally connected between the two sets of slide rails. A first drive gear and a second drive gear are respectively sleeved at both ends of the drive shafts. The gearbox drive assembly includes a drive motor and an idler gear installed on the flipping base. The output end of the drive motor is driven and connected to the drive gear. The drive gear is driven and transmitted to the first drive gear or the second drive gear through the idler gear.

[0007] Furthermore, a position sensor and a zero position sensor are respectively provided on the flip plate base and on the two ends of the flip plate body's flipping trajectory.

[0008] Furthermore, the flap support includes an arc-shaped frame that is fixedly connected to the flap body. The end of the arc-shaped frame is sleeved on the transmission shaft through a bearing. Two sets of arc-shaped racks are provided on both sides of the arc-shaped frame. The first transmission gear and the second transmission gear are each meshed with a set of arc-shaped racks.

[0009] Furthermore, arrays of driven bearings and arrays of side guide wheels are slidably nested in slide rails on both sides of the arc-shaped frame.

[0010] Furthermore, sensing plates for triggering position sensors and zero-position sensors are installed on the arc-shaped frame.

[0011] This application also proposes a sorting robot, which is equipped with a flip-plate mechanism designed with the features described above.

[0012] In summary, the advantages and benefits of this application are that it has the characteristics of simple structure and strong practicality, can significantly increase cargo load while saving limited equipment space, and can realize adjustable flip angle based on position detection, thus having strong promotional value.

Detailed Implementation

[0015] Example 1, such as Figures 1 to 3 As shown, this application proposes a novel flipping mechanism, including a flipping base 1-1 connected to the main body of the sorting machine robot, and a gearbox drive assembly installed on the flipping base 1-1. The gearbox drive assembly drives the flipping body 4 to flip vertically through the flipping bracket 3-1 to achieve cargo sorting. A set of recessed slide rails 1-9 are respectively provided on both sides of the top of the flip plate base 1-1. A set of transmission shafts 1-2 is pivotally connected between the two sets of slide rails 1-9. A first transmission gear 2-3 and a second transmission gear 2-4 are respectively sleeved at both ends of the transmission shaft 1-2. On the flip plate base 1-1, at both ends of the flip plate body 4, there are rotatable shafts with position sensors 1-4 installed by position detection sensor bracket 1-5 and zero position sensors 1-7 installed by zero position detection sensor bracket 1-6, thereby realizing the controllability of the flip angle adjustment. The gearbox drive assembly includes a drive motor 1-8 and an idler gear 2-2 mounted on the flip plate base 1-1. The output end of the drive motor 1-8 is driven and connected to the drive gear 2-1. The drive gear 2-1 is driven and transmitted to the first transmission gear 2-3 or the second transmission gear 2-4 through the idler gear 2-2. The flip plate base 1-1 provides the installation foundation for the entire flip plate mechanism. Driven by the drive motor 1-8, the drive gear 2-1 transmits torque and motion from the idler gear 2-2 through two sets of first transmission gears 2-3 and second transmission gears 2-4 to the flip plate bracket 3-1. The flip plate bracket 3-1 then drives the flip plate body 4 to flip.

[0016] The flip-plate bracket 3-1 includes an arc-shaped frame that is fixedly connected to the flip-plate body 4. The end of the arc-shaped frame is sleeved on the transmission shaft 1-2 through bearings. Two sets of arc-shaped racks 3-5, an array of driven bearings 3-4 and an array of side guide wheels 3-2 are provided on both sides of the arc-shaped frame, which are slidably nested in the slide rail 1-9, so as to be driven by the drive motor 1-8 to provide a standardized and smooth trajectory when the flip-plate bracket 3-1 flips. The driven bearing 3-4 and the side guide wheel 3-2, nested in the slide rail 1-9, slide or slide on the inner wall of the track when the flip plate bracket 3-1 moves to increase the smoothness of the flipping and reduce friction. The first transmission gear 2-3 and the second transmission gear 2-4 are each meshed with a set of arc-shaped racks 3-5 to realize the transmission of the flipping power. After the drive motor 1-8 drives the gearbox, the motion and torque are transmitted to the flip plate bracket 3-1. The arc-shaped racks 3-5 on the flip plate bracket 3-1 transmit the motion and torque to the flip plate body 4. The flip plate body 4 moves with the movement of the flip plate bracket 3-1 to realize the transportation and unloading of goods.

[0017] A sensor plate 3-3 is installed at the end of the arc-shaped frame to trigger the position sensor 1-4 and the zero position sensor 1-7 to adjust the angle of the flip plate.

[0018] Based on this, this application proposes a novel sorting robot, the top of which is equipped with a flip-plate mechanism designed in the above scheme.

[0019] The sorting process of the sorting robot is described below: After the drive motor 1-8 is powered on, the drive gear 2-1 rotates accordingly, and the idler gear 2-2 transmits the motion and torque of the drive gear 2-1 to the two sets of first transmission gears 2-3 and second transmission gears 2-4. Because the arc-shaped rack 3-5 on the flap support 3-1 meshes with two sets of transmission gears, the flap support 3-1 rotates along the rotation center, and the flap body 4 rotates accordingly. When the flap support 3-1 rotates to the zero position, the sensing plate 3-3 will align with the zero position detection sensor 1-7, and the flap support will stop at the zero position; when the flap support 3-1 rotates to the position, the sensing plate 3-3 will align with the position sensor 1-4, and the flap support 3-1 will stop rotating to the position; this process realizes the adjustable position of the flap. During the aforementioned flipping motion, the follower bearing 3-4 and the side guide wheel 3-2 will move along the slide rail 1-9 on the flip plate base 1-1, thereby reducing the friction between the flip plate base 1-1 and the flip plate bracket 3-1 and making the motion smoother.

[0020] In summary, the embodiments shown in the accompanying drawings are merely preferred solutions. Those skilled in the art can draw inspiration from these embodiments and directly derive other alternative structures that conform to the design concept of this utility model; all such alternative structures should fall within the scope of protection described in this application.
