Autonomous Mobile Cart Robot Arm for Board Work Object Transport
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In board manufacturing systems, operators face a significant workload in transporting objects such as nozzles, backup pins, and calibration jigs into and out of board work devices, which can lead to decreased productivity and requires dedicated storage space, increasing the complexity of the device structure.
Innovation Solution
An autonomous mobile cart equipped with a robot arm and a controller that automates the transportation of these objects within the movable range of board work devices, allowing the robot arm to deliver and receive objects without operator intervention, reducing the need for manual handling and storage space.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If an operator manually transports objects (nozzles, backup pins, calibration jigs) into and out of board work devices, then the board work devices can be simplified without additional storage structures, but the operator's work burden increases and productivity decreases
Solution Approach 1:
The autonomous mobile cart with robot arm performs the task of transporting objects into and out of board work devices automatically, without requiring operator intervention. The system serves itself by autonomously delivering objects to the working unit and receiving returned objects, thereby reducing operator workload while maintaining productivity.
Solution Approach 2:
The autonomous mobile cart acts as an intermediary between the object storage location and the board work devices. It receives objects from external storage and delivers them to the working unit, and vice versa for returned objects, thereby eliminating the need for manual transport by the operator while maintaining continuous manufacturing operations.
2Productivity
If dedicated storage space is provided for objects (nozzles, backup pins, calibration jigs) near board work devices, then object transport becomes faster and easier, but the device structure becomes more complex and occupies more space
Solution Approach 1:
The storage function is extracted from the board work device itself and placed externally. The autonomous mobile cart serves as a mobile storage unit that can deliver objects to the working unit when needed, eliminating the need for permanent dedicated storage structures within or near the board work devices, thereby maintaining structural simplicity while enabling fast object transport.
Solution Approach 2:
Instead of providing static dedicated storage spaces fixed near board work devices, the system uses a dynamic mobile cart that can move objects on demand. This dynamic approach allows fast object delivery when needed while avoiding the permanent structural complexity of fixed storage installations, as the cart can be repositioned or removed as needed.
3Device complexity
If the robot arm transports objects within the movable range of the working unit, then no additional storage structures are needed and device complexity is reduced, but the robot arm must be precisely controlled to deliver objects to the correct position
Solution Approach 1:
The working unit's movable range is designed to serve dual purposes: both performing the primary board work function and receiving objects delivered by the robot arm. By making the working unit's space universally usable for both operations, the system avoids the need for separate storage structures while maintaining the precision required for object delivery through coordinated control of the robot arm and working unit positioning.

AI summary
A board manufacturing system includes an autonomous mobile cart configured to transport an object used in board work devices of a mounting line, a robot arm provided on the autonomous mobile cart and configured to transport the object used in the board work devices to the board work devices, and a controller provided in the autonomous mobile cart and configured or programmed to control driving of the robot arm. The controller is configured or programmed to control the driving of the robot arm such that the robot arm transports the object used in the board work devices into and out of the board work devices within a movable range of a working unit in the board work devices in a plan view.
