Description

Technical Field

[0001] The utility model relates to the technical field of logistics transportation, in particular to an AGV unloading positioning device. Background Technique

[0002] The full name of AGV is Automated Guided Vehicle, which means "automated guided transport vehicle". An AGV trolley refers to a transport vehicle equipped with automatic guidance devices such as electromagnetic or optical ones, capable of traveling along a specified guidance path and having safety protection and various transfer functions.

[0003] At present, for the existing AGV transport forklift, during the process of lifting and lowering the transported materials, the transported materials may have a slight deviation in position due to the movement or stop of the trolley, thus having a certain impact on the accuracy of the position during unloading. The materials may have a deviation in position on the unloading platform, resulting in the manipulator being unable to accurately unload the materials on the trolley. Moreover, anti-collision rubber strips are provided at the front end of the existing AGV trolley to buffer the collision during the trolley's movement. However, when encountering a relatively strong impact, the anti-collision rubber strips cannot meet the actual needs, resulting in insufficient safety of the trolley during actual movement.

[0004] Based on this, the utility model designs an AGV unloading positioning device to solve the above problems. Content of the Utility Model

[0005] The purpose of the utility model is to solve the deficiencies existing in the prior art and propose an AGV unloading positioning device.

[0006] To achieve the above purpose, the utility model provides the following technical solution: an AGV unloading positioning device, including a vehicle body, a man-machine interface, a warning light, walking wheels, a vehicle board, auxiliary wheels, a gantry, a cross frame, a lifting oil cylinder, a lifting frame, a fork, a positioning component, and an anti-collision component. At the bottom end of the back of the vehicle body, two vehicle boards are fixedly connected. Auxiliary wheels are arranged at the tails of the two vehicle boards. A gantry is arranged between the two vehicle boards. The gantry is connected to the vehicle body. A cross frame is fixedly connected to the top of the gantry. Two lifting oil cylinders are symmetrically arranged on the cross frame. The lower ends of the two lifting oil cylinders are connected to the lifting frame.

[0007] As a preferred technical solution of the utility model, the lifting frame is slidably arranged in the gantry. The upper and lower ends of the lifting frame are respectively fixedly connected with an upper fixing plate and a lower fixing plate. The two ends of the upper fixing plate and the lower fixing plate are respectively connected with two side plates. A fixing rod is fixedly connected between the two side plates.

[0008] As a preferred technical solution of the present utility model, positioning components are further provided on the two side plates, two forklift tines are provided on the fixed rod, and a plurality of rollers are provided on the bottom plates of the forklift tines.

[0009] As a preferred technical solution of the present utility model, the positioning component includes a positive and negative thread screw rod, a driving motor, a guide rod and a positioning clamping plate. The positive and negative thread screw rod is movably installed between the two side plates. One end of the positive and negative thread screw rod is fixedly connected to the output end of the driving motor, and the driving motor is fixedly installed on the right side plate.

[0010] As a preferred technical solution of the present utility model, two guide rods are symmetrically arranged above and below the positive and negative thread screw rod. Both of the two guide rods are fixedly connected between the two side plates, and a positioning clamping plate is movably connected to the positive and negative thread screw rod and the two guide rods.

[0011] As a preferred technical solution of the present utility model, the positioning clamping plate includes a plate body, a connecting plate, a sliding block and a guiding block. Three connecting plates are fixedly connected to one side of the plate body. A sliding block is connected to the middle connecting plate, and guiding blocks are connected to the upper and lower connecting plates. The sliding block is in threaded connection with the positive and negative thread screw rod, and the guiding block is slidably sleeved on the guide rod.

[0012] As a preferred technical solution of the present utility model, the human-machine interaction interface is arranged above the front of the vehicle body, the warning light is arranged at the upper end of the vehicle body, and an anti-collision component is fixedly installed below the front of the vehicle body.

[0013] As a preferred technical solution of the present utility model, the anti-collision component includes an inner mounting plate, a telescopic rod, a spring and an outer protection plate. The inner mounting plate is fixedly connected to the vehicle body by bolts. Three telescopic rods are fixedly connected to the inner mounting plate. Springs are arranged on the outer sides of the three telescopic rods, and the front ends of the three telescopic rods and the springs are fixedly connected to the outer protection plate.

[0014] Compared with the prior art, the beneficial effects of the present utility model are:

[0015] 1. When the present utility model is in use, after lifting the material by the forklift tine, the driving motor is used to drive the positive and negative thread screw rod to rotate. The rotation of the positive and negative thread screw rod makes the two positioning clamping plates respectively threadedly connected to its positive thread and negative thread move towards each other to abut against both sides of the material. The plurality of rollers provided at the bottom of the forklift tine facilitate the lateral movement of the material, so as to cooperate with the positioning component to make the lifted material be centered on the forklift tine for auxiliary positioning of the material. At the same time, during transportation, the two positioning clamping plates can limit the material. When unloading, after the material is lowered to the ground of the unloading platform, the two positioning clamping plates are moved in the reverse direction to reset, so that the material can be accurately placed at the designated position and is not prone to deviation;

[0016] 2. When the present utility model is in use, through the anti-collision component provided at the front end of the vehicle body, when a collision occurs, first, the collision will occur on the outer protection plate, causing the outer protection plate to displace. At the same time, the spring compresses and the extension rod of the telescopic rod retracts. Under the action of the telescopic rod and the spring, the impact force is buffered to achieve elastic collision, which can further improve the safety during travel and play a good protective effect on the vehicle body.
