Problems solved by technology
[0010]Because there are working sections with different heights and different feeding requirements during the real-time adjustment process of the intelligent production line, the single-height roller structure cannot meet the needs of this scene. The lifting AGV is completely unable to realize the function of flexible feeding
In addition, the previous AGVs were mostly command-based operations, lacking dynamic interaction with the production line, making it difficult to respond to changes in production line operations in a timely manner, and unable to fully meet the operational needs of intelligent production lines

The invention discloses an AGV self-adaptive feeding system capable of actively integrating intelligent production line edge side state information. The AGV self-adaptive feeding system comprises an AGV main body and a feeding and discharging mechanism installed on the top of the AGV main body in a matched mode. The feeding and discharging mechanism comprises a lifting unit, a conveying belt unit, a height inspection unit and a camera. The AGV main body comprises an information integration unit, a mapping navigation unit, a movement unit and a control unit, and the information integration unit interacts with intelligent production line edge side equipment to obtain operation information; the mapping navigation unit is used for building a map for the intelligent production environment and carrying out multi-stage interval hybrid navigation on the AGV main body according to the map; the movement unit is used for moving the AGV main body according to a movement instruction; and the control unit sends the movement instruction to the movement unit according to the navigation information of the navigation unit and controls the feeding and discharging mechanism to operate according to the operation information. The AGV technology and the intelligent dynamic production line are combined, the industrial automation level is improved, the movement and feeding control precision is high, the application range is wide, and the edge side flexible feeding and discharging requirements of the intelligent production line can be met.
Description
technical field [0001] The invention relates to the field of AGV and its transportation technology, in particular to an AGV self-adaptive feeding system that actively integrates state information on the edge side of an intelligent production line. Background technique [0002] In the production line scenario, the use of AGV automatic guided vehicles for material transportation instead of labor is the trend of automation development today. The AGVs that exist on the market today generally have the following functions: [0003] (1) It can replace manual work, automatically load and carry materials; [0004] (2) Able to use vision, laser and other sensors to independently plan the route and proceed; [0005] (3) It can replace manual labor, and realize automatic loading and unloading through mechanisms such as lifting and rollers. [0006] Intelligent production line is a flexible, mobile and variable production line concept. This production line can realize product manufact...
