Dual-Arm Robot Conveyor Transfer for Extended Workpiece Reach
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional robots with movable conveyors are limited in their ability to transfer workpieces outside the range of their robotic arms, restricting the flexibility and efficiency of workpiece installation locations.
Innovation Solution
A robot system comprising a base with a first robotic arm and a second robotic arm, where the second robotic arm is movable in the longitudinal and width directions via a pivotable movable part, allowing it to place workpieces on a conveyor attached to the first robotic arm, enabling flexible workpiece transfer without location constraints.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the conveyor is fixed to the base and the robotic arm places workpieces on it, then the workpiece transfer is straightforward, but the installing location is limited and the system lacks flexibility
Solution Approach 1:
The conveyor is made movable by attaching it to the robotic arm instead of fixing it to the base. This dynamic configuration allows the conveyor to be positioned at different locations and angles, enabling the system to adapt to various installing locations and workpiece transfer requirements without being constrained by a fixed setup.
Solution Approach 2:
The robotic arm serves multiple functions: it acts as both the manipulator for placing workpieces and the mounting structure for the conveyor. This multi-functionality eliminates the need for separate fixed conveyor installations at different locations, allowing a single robotic arm-conveyor combination to handle various transferring destinations and configurations.
2Adaptability or versatility
If the second robotic arm has a fixed base position, then the system structure is simple, but the robotic arm cannot reach workpieces located outside its movable range
Solution Approach 1:
The base of the second robotic arm is made movable through a movable part that can change position relative to the base body. This allows the robotic arm to reach workpieces located outside its original movable range by repositioning its base, thereby expanding the effective work area without requiring a completely new robotic arm installation.
Solution Approach 2:
The base structure is divided into a base body and a movable part that can independently change position. This segmentation allows the robotic arm's base to be repositioned as needed while keeping the rest of the system structure relatively simple, achieving extended reach capability without overwhelming structural complexity.
3Productivity
If the conveyor is attached to the first robotic arm, then the conveyor can be moved within the arm's range, but the system requires coordination between two robotic arms
Solution Approach 1:
The functions of the first robotic arm (conveyor positioning) and the second robotic arm (workpiece placement) are merged into a coordinated system. The conveyor attached to the first arm moves to the appropriate position, and the second arm places workpieces on it, creating an integrated transfer system that improves productivity through automated coordination between the two arms.

AI summary
A robot is provided, which includes a base, a first robot fixed to the base at a base end thereof, and a second robot fixed to the base at a base end thereof. The first robot has a first robotic arm and a first robot hand attached to a tip end of the first robotic arm. The second robot has a second robotic arm and a second robot hand attached to a tip end of the second robotic arm. The first robot hand includes a conveyor, and the second robot hand includes a holding part configured to hold a workpiece. The second robot places the workpiece held by the holding part on a transferring surface of the conveyor of the first robot and releases the workpiece.
