Description

Technical Field

[0001] This utility model relates to the field of handling robot technology, specifically a handling robot with a lifting mechanism. Background Technology

[0002] Automated Guided Vehicles (AGVs) are transport vehicles equipped with electromagnetic or optical automatic guidance devices that enable them to travel along a predetermined path. They also feature safety protection and various transfer functions. These vehicles use fully automated control to replace manual labor, saving manpower and being easy to use. They have been widely used in the logistics and transportation industry. AGV robots can operate autonomously according to predetermined paths and tasks, reducing the risk of human error and accidents. They can also be integrated with other automated systems and equipment to automate and optimize logistics and production processes.

[0003] Chinese patent CN22067477U discloses an AGV handling robot with a lifting mechanism. It uses the forward and reverse rotation of a dual-head motor to drive the helical gear drive wheel to rotate through a connecting shaft, which in turn drives the helical gear driven wheel that meshes with it to rotate. This, in turn, drives the threaded screw to make a spiral upward or downward movement in the vertical direction. With the help of the bushing, it realizes the lifting or lowering function of the support platform, which makes it easier for the AGV handling robot to adapt to goods or workbenches of different heights, complete the load unloading task, and improve its applicability.

[0004] While the above-mentioned solution utilizes multiple screw rods for helical lifting to lift the support platform, the robot needs to be repositioned multiple times after transporting the goods to the unloading position to align the goods with the unloading point. This is not only inefficient but also poses a safety hazard of goods tipping over during repeated cornering adjustments. Therefore, we provide a handling robot with a lifting mechanism to solve these problems. Utility Model Content

[0005] To solve the above-mentioned technical problems, this utility model provides a handling robot with a lifting mechanism.

[0006] This utility model provides a handling robot with a lifting mechanism, comprising:

[0007] The vehicle body is equipped with a movable component for supporting the movement of the vehicle body.

[0008] A turntable is rotatably connected to the vehicle body, and a rotating assembly for driving the turntable to rotate is provided inside the vehicle body.

[0009] A support plate is installed above the vehicle body. The support plate has through holes. Two sets of linkage rods are fixedly connected to the bottom surface of the support plate. The bottom ends of the linkage rods penetrate the vehicle body and extend into the vehicle body. A lifting assembly is installed inside the vehicle body to drive the support plate to move up and down through the linkage rods.

[0010] Furthermore, the rotating assembly includes a first motor mounted on the vehicle body, and bevel gears are mounted on both the turntable and the output shaft of the first motor, with the two bevel gears meshing with each other.

[0011] Furthermore, the lifting assembly includes a second motor installed inside the vehicle body, a lead screw rotatably connected inside the vehicle body, transmission wheels installed on both the lead screw and the output shaft of the second motor, and the two transmission wheels are connected in a transmission manner. A linkage plate is threadedly connected to the lead screw, and the bottom end of the linkage rod is fixedly connected to the linkage plate.

[0012] Furthermore, two limiting blocks are installed on the bottom surface of the support plate, and the bottom end of the limiting blocks leaves space with the upper surface of the vehicle body.

[0013] Furthermore, the support plate is provided with two sets of rotating slots, each of which is rotatably connected to a connecting shaft, and each connecting shaft is fixedly connected to a shielding plate. The support plate is provided with an adjustment component for driving the shielding plate to rotate via the connecting shaft.

[0014] Furthermore, the adjustment assembly includes a control box fixedly connected to the support plate, an adjustment cavity is provided on the support plate, one end of the connecting shaft is located in the adjustment cavity, and a worm gear is fixedly connected to the connecting shaft. A worm is rotatably connected to the control box, and the worm meshes with the worm gear.

[0015] Compared with related technologies, the present invention provides the following beneficial effects:

[0016] I. This utility model, by setting a rotating component, allows the turntable to rotate independently when the support plate is lowered to a non-interference position, thereby achieving precise adjustment of the cargo position. This avoids the problem of traditional AGVs requiring multiple vehicle body movements to align with the unloading position, which not only greatly improves the efficiency of cargo loading and unloading, but also reduces the risk of cargo tipping due to frequent adjustments of the vehicle body angle, thus enhancing operational safety.

[0017] Second, by setting up a lifting component, this utility model enables the support plate to be raised and lowered, and the barrier plate can be flexibly adjusted to a vertical or parallel state according to actual needs, allowing the robot to complete load unloading tasks on workbenches at different heights, while supporting the handling of larger-sized goods, greatly expanding its application range. Furthermore, the self-locking mechanism of the worm gear and worm wheel ensures the stability of the barrier plate position in the non-operational state, further enhancing the reliability of the system.

[0023] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0024] The specific implementation of this utility model will be described in detail below with reference to specific embodiments.

[0025] like Figure 1-4 As shown, this utility model provides a technical solution: a handling robot with a lifting mechanism, including a vehicle body 1, a turntable 2 and a support plate 3.

[0026] The vehicle body 1 is equipped with a moving component for supporting the movement of the vehicle body 1. This moving component is an existing structure and can support and move the vehicle body 1 by rotating the upper wheel on the motor-driven shaft.

[0027] The turntable 2 is rotatably connected to the vehicle body 1. The vehicle body 1 is equipped with a rotating assembly for driving the turntable 2 to rotate. The rotating assembly includes a first motor 9 mounted on the vehicle body 1. Both the turntable 2 and the output shaft of the first motor 9 are equipped with bevel gears 10, and the two bevel gears 10 mesh with each other.

[0028] When it is necessary to rotate and adjust the cargo, the upper surface of the support plate 3 should be positioned below the upper surface of the turntable 2, so that only the cargo contacts the turntable 2. After the output shaft of the first motor 9 rotates, the turntable 2 will rotate synchronously under the action of the two bevel gears 10, thereby completing the position adjustment when unloading the cargo.

[0029] The support plate 3 is located above the vehicle body 1. The support plate 3 has a through hole 4, which prevents the support plate 3 from contacting the turntable 2 when it is lowered. Two sets of linkage rods 7 are fixedly connected to the bottom surface of the support plate 3. The bottom end of the linkage rod 7 passes through the vehicle body 1 and extends into the vehicle body 1. The vehicle body 1 is equipped with a lifting assembly for moving the support plate 3 up and down through the linkage rods 7.

[0030] In this embodiment, the lifting assembly includes a second motor 12 installed inside the vehicle body 1. A lead screw 13 is rotatably connected inside the vehicle body 1. Both the lead screw 13 and the output shaft of the second motor 12 are equipped with transmission wheels 14, and the two transmission wheels 14 are connected in a transmission manner. The transmission wheels 14 can be connected in a transmission manner through a chain. A linkage plate 11 is threadedly connected to the lead screw 13, and the bottom end of the linkage rod 7 is fixedly connected to the linkage plate 11.

[0031] When it is necessary to adjust the loading height, unloading height, or unloading angle, the output shaft of the second motor 12 rotates, and under the action of the transmission wheel 14, the lead screw 13 rotates inside the vehicle body 1, and the linkage plate 11 drives the support plate 3 to move up and down through the linkage rod 7.

[0032] Since two limiting blocks 19 are installed on the bottom surface of the support plate 3, and there is a space between the bottom end of the limiting block 19 and the upper surface of the vehicle body 1, the limiting block 19 will abut against the vehicle body 1 when the support plate 3 is lowered to the lowest position, thereby preventing the support plate 3 from contacting the first motor 9.

[0033] In this embodiment, the support plate 3 is provided with two sets of rotating grooves 5, each rotating groove 5 is rotatably connected to a connecting shaft 16, and each connecting shaft 16 is fixedly connected to a shielding plate 6. The support plate 3 is provided with an adjustment component for driving the shielding plate 6 to rotate through the connecting shaft 16.

[0034] On the one hand, the barrier 6 can be rotated to a state perpendicular to the support plate 3, thereby limiting the goods placed on the support plate 3. On the other hand, the barrier 6 can be rotated to a state parallel to the support plate 3, thereby enabling the support plate 3 to transport larger goods.

[0035] In this embodiment, the adjustment assembly includes a control box 8 fixedly connected to the support plate 3. The support plate 3 has an adjustment cavity 15. One end of the connecting shaft 16 is located in the adjustment cavity 15, and a worm gear 17 is fixedly connected to the connecting shaft 16. A worm 18 is rotatably connected to the control box 8, and the worm 18 meshes with the worm gear 17.

[0036] By utilizing the meshing action of the worm 18 and the worm wheel 17, the worm 18 can drive the connecting shaft 16 to rotate through the worm wheel 17, and adjust the rotation of the baffle plate 6. Moreover, the meshing action of the worm 18 and the worm wheel 17 has a self-locking effect.

[0037] The above description is merely an embodiment of this utility model and does not limit the patent scope of this utility model. Any equivalent structural or procedural transformations made based on the content of this utility model specification and drawings, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this utility model.
