AI Technical Summary

Technical Problem

During the automatic loading and unloading of trucks, the variety of trucks and the complex carriage planes have led to the challenge of AGV's adaptability and versatility. In addition, the small gap between pollutants and cargo in the carriage requires high accuracy of AGV, which can easily lead to cargo damage or loading and unloading failure. Problems of over-holding, skewed pickup and misalignment of goods often occur, resulting in scratches or inability to pick up goods.

Method used

An automatic loading and unloading system for unmanned forklifts is designed, equipped with a cross-movable wishbone and multiple cameras. Through the information captured by the camera on the side and above, the control system calculates the relative distance between the cargo edge and the cargo wall, adjusts the cross-moving amount and driving path of the fork arm to ensure that the cargo is released close to the cargo wall, and reserves a gap when unloading to avoid scratches. The system also includes a hyper-bucket detection module and an autonomous planning path module for handling cargo misalignment and hyperbucketing situations.

Benefits of technology

By accurately calculating the relative position of the cargo and the car wall, the system can effectively avoid cargo scratches, improve loading and unloading accuracy and efficiency, solve the problems of cargo misalignment, over-holding and crooked pickup, and ensure the safety and integrity of the cargo.

Abstract

The present invention relates to the technical field of automatic loading and unloading of logistics forklifts, specifically to an anti-slip system for unmanned forklifts in the scene of automatic loading and unloading of vans, including: an unmanned forklift and a control system, wherein the unmanned forklift is equipped with a fork arm that can be moved laterally, and cameras are installed on both sides of the unmanned forklift for photographing goods and the walls of the carriage during loading and unloading. The invention adopts a design scheme of camera layout on both sides, which has significant advantages. Through the high-precision cameras installed on both sides of the AGV fork arm, the AGV can accurately calculate the relative position relationship between the goods and the carriage wall through image processing and algorithm analysis, thereby adjusting the lifting height and moving trajectory of the fork arm to ensure that the goods are placed stably and accurately inside the carriage, effectively avoiding the occurrence of the problem of slipping goods.
