AI Technical Summary

Technical Problem

Existing bag palletizing devices suffer from problems such as easily scratching the bag body, inability to adapt to all sizes, difficulty in simultaneously performing gripping and inspection, and difficulty in identifying quality control defects online.

Method used

The device employs a flexible gripper based on octopus biomimicry, including a central base, multiple flexible extension arms, a negative pressure gripping unit, and a vision inspection unit, to achieve three-dimensional surround gripping, synchronous inspection, and palletizing. It also incorporates multimodal sensors for quality control defect identification.

Benefits of technology

It enables simultaneous, non-destructive grasping and inspection across the entire process, improving production line and quality control efficiency, reducing grasping defect rates and missed detection rates, and meeting export quality control requirements.

Abstract

This invention discloses a flexible gripper for bag palletizing based on octopus biomimicry and its control method. It employs a central base inspired by an octopus head, connecting multiple independently controllable three-segment biomimetic flexible extension arms. Each arm integrates a negative pressure suction cup, a miniature binocular vision module, and a multi-dimensional sensing unit at its end. The base integrates a main control, pneumatic, communication, and sensor processing unit. The control method includes three closed-loop controls: distributed multi-view collaborative shape reconstruction and feature recognition; integrated avoidance-adhesion non-destructive gripping planning; and synchronous gripping defect identification and traceability. This invention addresses the specific characteristics of bag palletizing scenarios, achieving full-area, non-destructive gripping, detection, gripping, and palletizing simultaneously, improving production line efficiency by over 40% and completely solving the core pain points of existing bag palletizing devices, such as high reliance on manual labor and high gripping defect rates.
