Embodiment 1

[0063] see Figure 1-7 , this embodiment provides an unmanned automatic guided vehicle, which can be called a mini unmanned AGV, which is mainly used to carry goods or materials, and does not need to be driven. Wherein, the unmanned automatic guided vehicle includes a car body 1, a fork leg 2, a driving wheel mechanism 3, a driven wheel mechanism 4, a hydraulic system 5 and an electric control system.

[0064] The car body 1 is the main part of the automatic guided vehicle. In this embodiment, the car body 1 is a shell structure, and other parts can be installed inside it. The car body 1 can adopt the car body 1 of existing AGV, and its specific size and shape can be set according to actual needs. Round corner design can be carried out around the car body 1, which can prevent the car body 1 from colliding with other objects and being damaged during driving. The surface of the vehicle body 1 can be coated with wear-resistant materials or other materials.

[0065] The number ...

Embodiment 2

[0084] This embodiment provides an unmanned automatic guided vehicle, which is similar to the unmanned automatic guided vehicle in Embodiment 1, except that the control unit 71 also has other functions. Wherein, the control unit 71 is used for judging whether the distance is smaller than a set threshold. When the distance is less than the set threshold, the control unit 71 drives the driving wheel mechanism 3 to stop, so as to protect the AGV from bumping into obstacles during operation, which can not only protect the automatic guided vehicle from damage, but also protect the moving path of the automatic guided vehicle surrounding objects.

Embodiment 3

[0086] This embodiment provides a cargo handling system, which includes a plurality of mini unmanned handling AGVs, and these mini unmanned handling AGVs cooperate with each other to transport a large amount of goods from different locations to the same point or multiple target locations. Wherein, the mini unmanned transport AGV is the unmanned transport automatic guided vehicle in embodiment 1 or embodiment 2. The path planning method between these mini unmanned handling AGVs adopts the existing path avoidance and operation mode between AGVs.

Abstract

The invention discloses an unmanned carrying automated guided vehicle and a guiding method thereof. The automated guided vehicle comprises a vehicle body, two fork legs, two driving wheel mechanisms,a driven wheel mechanism, a hydraulic system and a covering fork. Each driving wheel mechanism is installed in a corresponding fork leg. Each driving wheel mechanism comprises a servo motor, a drivingwheel, a bevel gear set, a driving shaft and a fixing plate. Each driving shaft is driven to rotate by the corresponding servo motor through the corresponding bevel gear set. The output shaft of eachservo motor is perpendicular to the corresponding driving shaft. The driving shafts are rotatably installed on the fixing plates. The fixing plates are fixed to corresponding fork legs. The driven wheel mechanism is installed in the vehicle body and comprises two driven wheels, a rotary frame, a rotary shaft and a first fixing seat. The hydraulic system comprises a pump station, a synchronous valve and two jacking devices. According to the unmanned carrying automated guided vehicle, the vehicle body does not move when the automated guided vehicle rises and falls, goods can be lifted and lowered smoothly, shaking of the goods is avoided, and stability of carrying can be improved; the overall dimension of the automatic guided vehicle (AGV) is lowered; and the navigation accuracy is improved.

Description

technical field [0001] The present invention relates to an automatic guided vehicle in the technical field of transport vehicles, in particular to an unmanned automatic guided vehicle, and also relates to a guiding method for the unmanned automatic guided vehicle of the automatic guided vehicle. Background technique [0002] AGV is an automatic guided vehicle. It is a battery-powered, unmanned automated handling vehicle equipped with a non-contact guiding device and an independent addressing system. A truck that does not require a driver in industrial applications is powered by a rechargeable battery. Generally, the computer can be used to control its travel path and behavior, or the electromagnetic track can be used to set up its travel path. The electromagnetic track is pasted on the floor, and the unmanned van relies on the information brought by the electromagnetic track to move and move. [0003] Among them, the pallet-type AGV is widely used and can be used in various...
