Solution Overview

Problem

Current robot picking mechanisms in warehouse logistics have complex structures, are heavy, and costly due to multiple joints and transmission mechanisms, which reduce warehouse space utilization and efficiency.

Innovation Solution

A hook mechanism with a carrier, driving component, and two hook pieces that move asynchronously, allowing simultaneous control of both pieces for picking and placing in different directions, simplifying the structure and reducing weight and costs.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If a mechanical hand with multiple joints and transmission mechanisms is used for picking and placing, then the robot can complete operations, but the structure becomes complex and weight increases

Engineering Contradiction:
Improvepicking and placing capabilityVSAvoidstructure complexity
Core Design Contradiction:
Ease of operationVSDevice complexity

Solution Approach 1:

The patent extracts and removes the complex mechanical hand with multiple joints and transmission mechanisms from the robot system. Instead, it introduces a simplified hook mechanism that directly performs picking and placing operations without requiring elaborate transmission systems, thereby reducing structural complexity while maintaining operational capability.

Inventive Principle:
Principle #2Taking out (Extraction)

Solution Approach 2:

The patent replaces the traditional mechanical hand system with a hook-based mechanism. This substitution eliminates multiple joints and transmission mechanisms, using a simpler mechanical configuration that achieves the same picking and placing function with reduced complexity and weight.

AI summary

The present disclosure provides a hook mechanism, a picking and placing device, a robot, a warehouse system, and a picking and placing method, and relates to the field of warehouse logistics technologies. The hook mechanism is used for picking and placing a container. The hook mechanism includes a carrier, a driving component, and two hook pieces. The driving component is disposed on the carrier. The two hook pieces are disposed at an interval along a first direction. The driving component is configured to drive at least two hook pieces to be respectively raised or lowered relative to the carrier, so that one drive can control two different hook pieces separately to pick and place the container in different directions, thereby simplifying a structure of the hook mechanism.
